A criterion for M\"uger centralizer of a fusion subcategory of a braided non-degenerate fusion category is given. Along the way we extend some identities on the space of class functions of a fusion category introduced by Shimizu in \cite{scalg}. We also show that in a modular tensor category the product of two conjugacy class sums is a linear combination of conjugacy class sums with rational coefficients.
We present a model in which the dark matter particle is frozen-in at MeV scale. In this model, the mediator between the standard model sector and the dark sector can automatically provide a self-interaction for dark matter. The interaction strength is naturally to be the in the region in favor of the cluster mass deficit anomaly. Due to the self-scattering, the Lyman-$\alpha$ constraint can be relaxed to $m_D \gtrsim 2 $ keV. In this region the self-interaction and the Fermi pressure both play roles on forming a dark matter core at the center of the dwarf galaxies.
We propose a scenario in which the Planck scale is dynamically linked to the electroweak scale induced by top condensation. The standard model field content, without the Higgs, is promoted to a 5D warped background. There is also an additional 5D fermion with the quantum numbers of the right-handed top. Localization of the zero-modes leads, at low energies, to a Nambu-Jona-Lasinio model that also stabilizes the radion field dynamically thus explaining the hierarchy between the Planck scale and v_EW = 174 GeV. The top mass arises dynamically from the electroweak breaking condensate. The other standard model fermion masses arise naturally from higher-dimension operators, and the fermion mass hierarchies and flavor structure can be explained from the localization of the zero-modes in the extra dimension. If any other contributions to the radion potential except those directly related with electroweak symmetry breaking are engineered to be suppressed, the KK scale is predicted to be about two orders of magnitude above the electroweak scale rendering the model easily consistent with electroweak precision data. The model predicts a heavy (composite) Higgs with a mass of about 500 GeV and standard-model-like properties, and a vector-like quark with non-negligible mixing with the top quark and mass in the 1.6 - 2.9 TeV range. Both can be within the reach of the LHC. It also predicts a radion with a mass of a few GeV that is very weakly coupled to standard model matter.
The Laser Interferometer Gravitational Wave Observatory (LIGO) and Virgo Collaboration's Observing Run 3 has demanded the development of widely-applicable tools for gravitational wave follow-up. These tools must address the main challenges of the multi-messenger era, namely covering large localisation regions and quickly identifying decaying transients. To address these challenges, we present a public web interface to assist astronomers in conducting galaxy-targeted follow-up of gravitational wave events by offering a fast and public list of targets post-gravitational wave trigger. After a gravitational wave trigger, the back-end galaxy retrieval algorithm identifies and scores galaxies based on the LIGO and Virgo computed probabilities and properties of the galaxies taken from the Galaxy List for the Advanced Detector Era (GLADE) V2 galaxy catalogue. Within minutes, the user can retrieve, download, and limit ranked galaxy lists from the web application. The algorithm and website have been tested on past gravitational wave events, and execution times have been analysed. The algorithm is being triggered automatically during Observing Run 3 and its features will be extended if needed. The web application was developed using the Python based Flask web framework. The web application is freely available and publicly accessible at gwtool.watchertelescope.ie.
One of the biggest problems holding back health care in Canada is that, the moment anyone so much as HINTS at copying something that is working well in somewhere like the U.K. or France there is instantly a massive outcry of "We don't want a U.S. style health care system!!!". As a result we can't change to copy what places like France or Sweden might have done because of problems in the U.S. system. Obviously this makes no sense at all to anyone who spends a microsecond thinking logically about things, yet one need only read the comments above mine to see examples of this exact behaviour. Somehow ANY change to health care is viewed as moving us toward that boogeyman of the U.S. health care system and, as a result, we're stuck with our poorly performing system.
Mirror is built well, but light is dim & batteries die FAST The mirror itself seems to be very good quality and is very easy to adjust to find the right angle. The lighting is my only issue and doesn't really work. To be dairy, I don't remember seeing a mirror with LED lights that other reviewers were satisfied with, so I tried this one since it was a good price. I've only used the lights about 5 times, and the batteries already died. The remote is a nice feature, but considering how fast the batteries died, you probably have to turn the switch off on the mirror after you finish driving, which kinda defeats the purpose of having a remote. As a mirror, it's great, but I don't know if there is one on Amazon with proper lighting.
In colored graphs, node classes are often associated with either their neighbors class or with information not incorporated in the graph associated with each node. We here propose that node classes are also associated with topological features of the nodes. We use this association to improve Graph machine learning in general and specifically, Graph Convolutional Networks (GCN). First, we show that even in the absence of any external information on nodes, a good accuracy can be obtained on the prediction of the node class using either topological features, or using the neighbors class as an input to a GCN. This accuracy is slightly less than the one that can be obtained using content based GCN. Secondly, we show that explicitly adding the topology as an input to the GCN does not improve the accuracy when combined with external information on nodes. However, adding an additional adjacency matrix with edges between distant nodes with similar topology to the GCN does significantly improve its accuracy, leading to results better than all state of the art methods in multiple datasets.
In 1996 Jespers and Wang classified finite semigroups whose integral semigroup ring has finitely many units. In a recent paper, Iwaki-Juriaans-Souza Filho continued this line of research by partially classifying the finite semigroups whose rational semigroup algebra %over a field of characteristic zero, contains a ${\mathbb{Z}}$-order with hyperbolic unit group. In this paper we complete this classification by handling the case in which the semigroup is semi-simple.
Easy to use While this little gadget has been helpful during nursing school for recording lectures, it is now not working (2 years of use)-I haven't finished nursing school yet, and am right in the middle of a semester :'( Pros: extremely easy to use! Cons: can sometimes be accidentally switched on in a bag; always has to have the time/date reset
The existence and properties of an exact universal excitation waveform for optimal enhancement of directed ratchet transport are deduced from the criticality scenario giving rise to ratchet universality, and confirmed by numerical experiments in the context of a driven overdamped Brownian particle subjected to a vibrating periodic potential. While the universality scenario holds regardless of the waveform of the periodic vibratory excitations involved, it is shown that the enhancement of directed ratchet transport is optimal when the impulse transmitted by those excitations (time integral over a half-period) is maximum. Additionally, the existence of a frequency-dependent optimal value of the relative amplitude of the two excitations involved is illustrated in the simple case of harmonic excitations.
We show that the exact ground state of the Lieb-Mattis Hamiltonian is an equal-weight superposition of all possible classical N\'{e}el states, and provide an exact formulation of this superposition in the $z$-spin basis for both $S=1/2$ and general $S$ using Schwinger bosons. In general, a superposition of possible rotations on a general initial state is symmetric if and only if the initial state has a nonzero overlap with a singlet state and is otherwise made up of states that vanish due to the symmetrization. Most notably, $\|s, m=0 \rangle$ states will vanish if symmetrized, which explains how a superposition of N\'{e}el states projects onto its singlet component.
We describe an efficient near-field to far-field transformation for optical quasinormal modes, which are the dissipative modes of open cavities and plasmonic resonators with complex eigenfrequencies. As an application of the theory, we show how one can compute the reservoir modes (or regularized quasinormal modes) outside the resonator, which are essential to use in both classical and quantum optics. We subsequently demonstrate how to efficiently compute the quantum optical parameters necessary in the theory of quantized quasinormal modes [Franke et al., Phys. Rev. Lett. 122, 213901 (2019)]. To confirm the accuracy of our technique, we directly compare with a Dyson equation approach currently used in the literature (in regimes where this is possible), and demonstrate several order of magnitude improvement for the calculation run times. We also introduce an efficient pole approximation for computing the quantized quasinormal mode parameters, since they require an integration over a range of frequencies. Using this approach, we show how to compute regularized quasinormal modes and quantum optical parameters for a full 3D metal dimer in under one minute on a standard desktop computer. Our technique is exemplified by studying the quasinormal modes of metal dimers and a hybrid structure consisting of a gold dimer on top of a photonic crystal beam. In the latter example, we show how to compute the quantum optical parameters that describe a pronounced Fano resonance, using structural geometries that cannot practically be solved using a Dyson equation approach. All calculations for the spontaneous emission rates are confirmed with full-dipole calculations in Maxwell's equations and are shown to be in excellent agreement.
...then they will have a proper place to file this crap. Sorry, not a "mystery" as claimed, it is religious mumbo-jumbo. I kept waiting for the "unimaginable evil" that was promised me, but the "evil" in this flick would only be unimaginable by a five year old with learning disabilities.<br /><br />I can't believe that they actually managed to find some bigger name actors willing to be involved in this embarrassment. Unfortunately it has forevermore changed my opinion of them, and I will likely avoid anything they do in the future. I'm also a little cheesed off that I now have a writer's name and director's name to memorize as I'll be avoiding anything they do like the plague from now on too.<br /><br />It's really unfortunate that all the religious fanatics posting on here and saying that this movie is 10 out of 10, etc. will get their reviews posted first. This could lead to more people getting tricked, as I was, into believing this movie was something other than religious preaching.<br /><br />Well, it's off to the video store to get my money back for false advertising. Too bad they can't give me back the 105 minutes I wasted watching this thinking that it was actually a Hollywood horror/supernatural film.
The renormalization of the Wiedemann-Franz (WF) ratio in strongly correlated electron systems is analyzed within the Landau quasiparticle picture. We demonstrate that the WF law is violated: (i) at the quantum critical point, where the effective mass diverges, and (ii) beyond a point of fermion condensation, where the single-particle spectrum $\epsilon(p)$ becomes flat. Results of the analysis are compared with available experimental data.
I want to start by stating I am a republican, even though I don't agree with a lot of the things bush has done in office. And I love the daily show and Colbert report. They have to be two of my favorite shows on TV. I enjoy the bush jokes on Conan, Letterman, Leno, because I admit that W is not the smartest guy to ever walk the earth(I do believe he's not the dumbest either.) But it comes to a point when enough is enough and it's not really that funny anymore. I see where it can be funny and it is(hey he's making fun of our authority figure he's hilarious.). Comedy central though is just trying to hard to poke fun at him. I mean maybe one special episode, but an entire series is just dumb. It seems CC is just saying the same bush jokes that we've heard WAY to many times. I really cannot see this show going past 1 season.
We study the inverse problem in the difference Galois theory of linear differential equations over the difference-differential field $\mathbb{C}(x)$ with derivation $\frac{d}{dx}$ and endomorphism $f(x)\mapsto f(x+1)$. Our main result is that every linear algebraic group, considered as a difference algebraic group, occurs as the difference Galois group of some linear differential equation over $\mathbb{C}(x)$.
We study the statistics of large deviations of the intensive work done in an interaction quench of a one-dimensional Bose gas with a large number N of particles, system size L and fixed density. We consider the case in which the system is initially prepared in the non-interacting ground state and a repulsive interaction is suddenly turned on. For large deviations of the work below its mean value, we show that the large deviation principle holds by means of the quench action approach. Using the latter, we compute exactly the so-called rate function, and study its properties analytically. In particular, we find that fluctuations close to the mean value of the work exhibit a marked non- Gaussian behavior, even though their probability is always exponentially suppressed below it as L increases. Deviations larger than the mean value, instead, exhibit an algebraic decay, whose exponent can not be determined directly by large-deviation theory. Exploiting the exact Bethe ansatz representation of the eigenstates of the Hamiltonian, we calculate this exponent for vanishing particle density. Our approach can be straightforwardly generalized to quantum quenches in other interacting integrable systems.
This is an extremely boring film. If you grew up during the Vietnam Was, as I did, then you've seen and heard all of the film footage and arguments here a hundred times by now. But what really makes this film boring is the narration by director Carlton Sherwood. The majority of the film is shot with Sherwood talking directly into the camera about his opinion of this conflicting time in the history of our nation.<br /><br />If you're old enough to remember Vietnam, then you won't find anything new here. There is no new evidence to condemn John Kerry or new evidence worthy of another documentary on Vietnam. Younger viewers who are interested in the subject should see George Butler's excellent film Going Upriver! Stolen Honor was clearly meant to be a hatchet job on John Kerry, but it fails miserably at accomplishing that goal.
She is a rusted out movie star and Oil towns will be rusted out wrecks of towns. Each similar. You know you will grow old and "Rust", and we know that Oil towns will die and rust out. The one difference is Mrs. Fonda (whether right or wrong in her stance) knows she is going to die. Northern Oil Towns, are still in denial. Sad sight really.
A mathematical analysis of the distribution of voting power in the Council of the European Union operating according to the Treaty of Lisbon is presented. We study the effects of Brexit on the voting power of the remaining members, measured by the Penrose--Banzhaf Index. We note that the effects in question are non-monotonic with respect to voting weights, and that some member states will lose power after Brexit. We use the normal approximation of the Penrose--Banzhaf Index in double-majority games to show that such non-monotonicity is in most cases inherent in the double-majority system, but is strongly exacerbated by the peculiarities of the EU population vector. Furthermore, we investigate consequences of a hypothetical "generalized Brexit", i.e., NN-exit of another member state (from a 28-member Union), noting that the effects on voting power are non-monotonic in most cases, but strongly depend on the size of the country leaving the Union.
We introduce the notions of boundary vertex, linear equivalence and effective boundary vertex in the context of Viennot's heaps of pieces. We prove that in the heap of a fully commutative element in a star reducible Coxeter group, every boundary vertex is linearly equivalent to an effective boundary vertex. Using this result, we establish Property W (in the sense of math.QA/0509363) for star reducible Coxeter groups; this corrects a mistake in the latter paper.
This was really a pleasure to see; the dialogue was - for the most part - absolutely outstanding (I thought the women's roles were a little better written, which is a nice surprise). The performances were uniformly very good, too. Frank Gorshin overdoes it a little when he goes into his various cons, but this might be his overcompensating for what I see as weaknesses in how the character is written; he's VERY good otherwise. Harry Groener does similarly well with a slightly underwritten character (Tony), overdoing some of the character's angrier scenes slightly. Ursula Burton is excellent as Sister Theresa, really carrying the film through some of its weaknesses. Seymour Cassel and Louise Fletcher are a little underused here, though I liked their work as always. Shirley Jones, Wendie Malick, Jill Eikenberry and Faye Grant are very good also (I couldn't help thinking Grant reminded me a little of Catherine O'Hara here); Cloris Leachman rather tears into her role, with reasonably good results.<br /><br />I wish there had been more of a sure hand behind the camera, though. Sometimes the framing or staging seemed a bit off, or awkward. The closeups seemed overused (or erratically used) to me. And we don't always go from scene to scene as smoothly as we'd like. Some of the "tough guy" approach to the federal agent (music, costuming) was too over the top for me as well. And the few fantasy sequences didn't really work. But there are things that were VERY well done; the opening sequence set in Buffalo around 1970, for example. And, frankly, all of the scenes regarding Theresa's church work (I suspect the writer and actress liked the character a lot, which helps). The scenes between Malick and Eikenberry are VERY good.<br /><br />The plot is probably a bit overcontrived - there seem to be a few too many schemes going on at once to keep them all straight at times, and the coincidences got to be a little too much. And I was a little bothered by the ending (should we REALLY be rooting for their biggest con yet to succeed?), but the ride along the way is very enjoyable. It would be nice to see more independent movies like this one made.<br /><br />7 of 10
Not worth it I really like the design of the backpack, but it is not practical for a college student. This is a good backpack to hold maybe 2 books. There’s days where I walk almost 2 miles because of my classes and my back is hurting and aching. It’s a very bulky backpack and doesn’t fit much in it. I have to shove things back in if I take something out. I also cannot have my 15” laptop in it without taking something else out. It also smelled strong of plastic when I first got it. I’m going to be upgrading from this backpack.
Various statistical analysis methods are studied for years to extract accurate trends of network traffic and predict the future load mainly to allocate required resources. Besides, many stochastic modeling techniques are offered to represent fundamental characteristics of different types of network traffic. In this study, we analyze autoregressive traffic forecasting techniques considering their popularity and wide-use in the domain. In comparison to similar works, we present important traffic characteristics and discussions from the literature to create a self-consistent guidance along with the survey. Then, we approach to techniques in the literature revealing which network characteristics they can capture offering a characteristic-based framework. Most importantly, we aim to fill the gap between the statistical analysis of those methods and their relevance with networking by discussing significant aspects and requirements for accurate forecasting from a network-telemetric perspective.
We consider a minimal Lee-Wick (LW) extension to the Standard Model in which the fields providing the most important contributions to the cancellation of quadratic divergences are the lightest. Partners to the SU(2) gauge bosons, Higgs, top quark, and left-handed bottom quark are retained in the low-energy effective theory, which is valid up to approximately 10 TeV; the remaining LW partners appear above this cutoff and complete the theory in the ultraviolet. We determine the constraints on the low-energy spectrum from the electroweak parameters S and T, and find LW states within the kinematic reach of the LHC at the 95% confidence level.
GRS 1915+105 was observed by BeppoSAX for about 10 days in October 2000. For about 80% of the time, the source was in the variability class $\rho$, characterised by a series of recurrent bursts. We describe the results of the timing analysis performed on the MECS (1.6--10 keV) and PDS (15--100 keV) data. The X-ray count rate from \grss showed an increasing trend with different characteristics in the various energy bands. Fourier and wavelet analyses detect a variation in the recurrence time of the bursts, from 45--50 s to about 75 s, which appear well correlated with the count rate. From the power distribution of peaks in Fourier periodograms and wavelet spectra, we distinguished between the {\it regular} and {\it irregular} variability modes of the $\rho$ class, which are related to variations in the count rate in the 3--10 keV range. We identified two components in the burst structure: the slow leading trail, and the pulse, superimposed on a rather stable level. We found that the change in the recurrence time of the regular mode is caused by the slow leading trails, while the duration of the pulse phase remains far more stable. The evolution in the mean count rates shows that the time behaviour of both the leading trail and the baseline level are very similar to those observed in the 1.6--3 and 15--100 keV ranges, while that of the pulse follows the peak number. These differences in the time behaviour and count rates at different energies indicate that the process responsible for the pulses must produce the strongest emission between 3 and 10 keV, while that associated with both the leading trail and the baseline dominates at lower and higher energies
Quantum error correction is widely thought to be the key to fault-tolerant quantum computation. However, determining the most suited encoding for unknown error channels or specific laboratory setups is highly challenging. Here, we present a reinforcement learning framework for optimizing and fault-tolerantly adapting quantum error correction codes. We consider a reinforcement learning agent tasked with modifying a family of surface code quantum memories until a desired logical error rate is reached. Using efficient simulations with about 70 data qubits with arbitrary connectivity, we demonstrate that such a reinforcement learning agent can determine near-optimal solutions, in terms of the number of data qubits, for various error models of interest. Moreover, we show that agents trained on one setting are able to successfully transfer their experience to different settings. This ability for transfer learning showcases the inherent strengths of reinforcement learning and the applicability of our approach for optimization from off-line simulations to on-line laboratory settings.
Ultranonocrystalline diamond/hydrogenated amorphous carbon composite thin films consist of three different components; ultrananocrystalline diamond crystallites, hydrogenated amorphous carbon, and grain boundaries between them. Since grain boundaries contain a lot of dangling bonds and unsaturated bonds, they would be a cause of carrier trap center degrading device performance in possible applications such as UV photo-detectors. We experimentally demonstrate hydrogen atoms preferentially incorporate at grain boundaries and terminate dangling bonds by means of several spectroscopic techniques. XPS measurements cannot detect quantitative transitions of sp^2- and sp^3-hybridized carbons in the films, resulting in 55-59 % of sp^3 contents. On the other hand, FT-IR and NEXAFS exhibit some variations of the amounts of certain carbon hybridization for sure. The former confirms the transformation from sp^2 to sp^3 hydrocarbons by ~10 % by additional hydrogenation, and the latter represents chemical configuration changes from {\pi}* C{\equiv}C and {\pi}* C=C to {\sigma}* C-H. These results can be an evidence of localized hydrogen at grain boundaries, which plays a part in terminating dangling bonds and unsaturated bonds, and they are correlated with the optical and electrical properties of the films investigated in some previous research. Our spectroscopic studies on the hydrogenation effects combined with the discussion on the optical and electrical characteristics confirm that the hydrogenation can be an effective tool of an enhancement of photovoltaic performance in the above sensing applications.
Biomedical researchers are moving towards high-throughput screening, as this allows for automatization, better reproducibility and more and faster results. High-throughput screening experiments encompass drug, drug combination, genetic perturbagen or a combination of genetic and chemical perturbagen screens. These experiments are conducted in real-time assays over time or in an endpoint assay. The data analysis consists of data cleaning and structuring, as well as further data processing and visualisation, which, due to the amount of data, can easily become laborious, time consuming, and error-prone. Therefore, several tools have been developed to aid researchers in this data analysis, but they focus on specific experimental set-ups and are unable to process data of several time points and genetic-chemical perturbagen screens together. To meet these needs, we developed HTSplotter, available as web tool and Python module, that performs automatic data analysis and visualisation of either endpoint or real-time assays from different high-throughput screening experiments: drug, drug combination, genetic perturbagen and genetic-chemical perturbagen screens. HTSplotter implements an algorithm based on conditional statements in order to identify experiment type and controls. After appropriate data normalization, HTSplotter executes downstream analyses such as dose-response relationship and drug synergism by the Bliss independence method. All results are exported as a text file and plots are saved in a PDF file. The main advantage of HTSplotter over other available tools is the automatic analysis of genetic-chemical perturbagen screens and real-time assays where results are plotted over time. In conclusion, HTSplotter allows for the automatic end-to-end data processing, analysis and visualisation of various high-throughput in vitro cell culture screens, offering major improvements in terms of versatility, convenience and time over existing tools. Author summaryAcademic researchers are moving towards high-throughput screenings, where the experiments execution follows an automatic approach, such as robotic seeding, liquid dispensing and/or automatics readouts. This grants more flexible and reproducible experimental set ups. The type of high-throughput experiment can vary from drug, drug combination, genetic perturbagen to genetic-chemical perturbagen screens. These can be assessed through endpoint assays, measuring the effect at one time point, or real-time assays, assessing the phenotypic effect over time. High-throughput screening results in large amounts of data, requiring laborious, time consuming and error-prone data handling and analysis. These challenges hamper the biological interpretation of data and the fast progress in drug development programs. Hence, we developed HTSplotter, a web tool and Python module, to allow researchers to conduct a fast and flexible end-to-end data processing, analysis and visualisation of different high-throughput experiments, assessed either by endpoint or real-time assays, relieving the high-throughput analysis bottleneck. In this way, HTSplotter, directly contributes to a faster identification of drugs and drug combinations, with potential practical applications, or novel targets for therapies.
CS: Thank you for your kind words. We often disagree on issues but that doesn't mean we can't discuss issues in a civil fashion. The Russian involvement has been investigated and, according to the FBI and NSA, has been validated. The possible involvement of Trump Campaign officials has been alleged but, as you say, not established. I do think a special counsel investigation would be merited. As I said before, investigations can establish both innocence and/or guilt...A truly independent investigation would clear the air. "This is not a thirld world country where political opponents are persecuted on allegations" I agree on this. That's why Trump's comments and Trump followers chanting "Lock Her Up" bother me. regards, Gary Crum
Wigner functions provide a way to do quantum physics using quasiprobabilities, that is, "probability" distributions that can go negative. Informationally complete POVMs, a much younger subject than phase space formulations of quantum mechanics, are less familiar but provide wholly probabilistic representations of quantum theory. In this paper, we show that the Born Rule links these two classes of structure and discuss the art of interconverting between them. In particular, we demonstrate that the operator bases corresponding to minimal discrete Wigner functions (Wigner bases) are orthogonalizations of minimal informationally complete measurements (MICs). By not imposing a particular discrete phase space structure at the outset, we push Wigner functions to their limits in a suitably quantified sense, revealing a new way in which the symmetric informationally complete measurements (SICs) are significant. Finally, we speculate that astute choices of MICs from the orthogonalization preimages of Wigner bases may in general give quantum measurements conceptually underlying the associated quasiprobability representations.
'When one team of researchers interviewed fourth-, fifth- and sixth-graders at an urban California high school, they found that more than half of them didn’t know pickles were cucumbers, or that onions and lettuce were plants'. Anyone living in more rural areas would know chocolate milk doesn't comes from brown cows. Rural area are typically Republican voters. On the other hand urban individuals would be more likely to think something along those lines typically Democrat voters. Common sense and logic!!
We investigate deep learning autoencoders for the unsupervised recognition of phase transitions in physical systems formulated on a lattice. We focus our investigation on the 2-dimensional ferromagnetic Ising model and then test the application of the autoencoder on the anti-ferromagnetic Ising model. We use spin configurations produced for the 2-dimensional ferromagnetic and anti-ferromagnetic Ising model in zero external magnetic field. For the ferromagnetic Ising model, we study numerically the relation between one latent variable extracted from the autoencoder to the critical temperature $T_c$. The proposed autoencoder reveals the two phases, one for which the spins are ordered and the other for which spins are disordered, reflecting the restoration of the $\mathbb{Z}_2$ symmetry as the temperature increases. We provide a finite volume analysis for a sequence of increasing lattice sizes. For the largest volume studied, the transition between the two phases occurs very close to the theoretically extracted critical temperature. We define as a quasi-order parameter the absolute average latent variable ${\tilde z}$, which enables us to predict the critical temperature. One can define a latent susceptibility and use it to quantify the value of the critical temperature $T_c(L)$ at different lattice sizes and that these values suffer from only small finite scaling effects. We demonstrate that $T_c(L)$ extrapolates to the known theoretical value as $L \to \infty$ suggesting that the autoencoder can also be used to extract the critical temperature of the phase transition to an adequate precision. Subsequently, we test the application of the autoencoder on the anti-ferromagnetic Ising model, demonstrating that the proposed network can detect the phase transition successfully in a similar way.
Use of an error correction code in a given transmission channel can be regarded as the statistical experiment. Therefore, powerful results from the theory of comparison of experiments can be applied to compare the performances of different error correction codes. We present results on the comparison of block error correction codes using the representation of error correction code as a linear experiment. In this case the code comparison is based on the Loewner matrix ordering of respective code matrices. Next, we demonstrate the bit-error rate code performance comparison based on the representation of the codes as dichotomies, in which case the comparison is based on the matrix majorization ordering of their respective equivalent code matrices.
We analyze two dedicated NuSTAR observations with exposure ${\sim}190$ ks located ${\sim}10^\circ$ from the Galactic plane, one above and the other below, to search for x-ray lines from the radiative decay of sterile-neutrino dark matter. These fields were chosen to minimize astrophysical x-ray backgrounds while remaining near the densest region of the dark matter halo. We find no evidence of anomalous x-ray lines in the energy range 5--20 keV, corresponding to sterile neutrino masses 10--40 keV. Interpreted in the context of sterile neutrinos produced via neutrino mixing, these observations provide the leading constraints in the mass range 10--12 keV, improving upon previous constraints in this range by a factor ${\sim}2$. We also compare our results to Monte Carlo simulations, showing that the fluctuations in our derived limit are not dominated by systematic effects. An updated model of the instrumental background, which is currently under development, will improve NuSTAR's sensitivity to anomalous x-ray lines, particularly for energies 3--5 keV.
If you've never experienced the thing that is Zasu Pitts, here is a Zasu zinger! In 1933 Mae Questel caricatured Pitt's voice for the character Olive Oyl for the Fleischer Studios animated cartoon version of the comic strip Popeye. Zasu (pronounced Zay-Sue) does her best "Olive Oyl" impersonation walking around whining and ringing her hands or attaching herself to the policeman's laynard. I kept waiting for her to say "ohhh myyyy", but instead it's "something always happens to somebody." The first time I saw this film I loved Zasu and found her character really funny. I've since seen her in other films where she does this same whining, uptight, fragile-flower routine. So, upon watching this film again I started getting a little annoyed with the constant whining and near hysteria over a piece of dust. But, there are some funny comedy bits here, and it's also a mystery movie as well. It's an interesting mix of mystery and comedy that actually works. The mystery plot holds together well through the camp of Zasu Pitts and James Gleason who plays Arthur Crimmer the policeman. The haunted House is fun with many a secret passage and even a skeleton in the attic! Well worth the watch. Read more public domain movie reviews at: http://pdmoviereview.blogspot.com/
A delight mini movie, a musical short based on three of Cole Porter's Broadway smash songs. Bob Hope's first credited film is a delight! He plays an American playboy millionaire on vacation in Paris. The film opens with him sitting at a table of an out door café telling his friends about this beauty that takes his breath away. Suddenly he spots her a few yards away. he is so over come his friends tease him and suggest "just show her your bank book." But Hope claims he can win her in less than 30 days with "no" money! They bet polo ponies over the issue and take all his cash and ID's. Hope follows her and when they are alone gushes out a proposal she does not believe he is sincere until he sings to her, "You Do Something to Me" by Cole Porter. But she must leave and he tries to earn money as a tour guide so he can pursue her. But when she sees him showing another girl around town, disillusioned she wants to drop him. He continues to chase her and catches up to her and her family at a race track where he bets his meager earnings on the last race hoping to win enough to impress her. Through a series of events and large synchronized dance numbers he loses the winning ticket and she decides to marry him rich or poor. So he wins the girl, the race and the bet and sings two more songs!
Most of current neural network models in quantum chemistry (QC) exclude the molecular symmetry, separate the well-correlated real space (R space), and momenta space (K space) into two individuals, which lack the essential physics in molecular chemistry. In this work, by endorsing the molecular symmetry and elementals of group theory, we propose a comprehensive method to apply symmetry in the graph neural network (SY-GNN), which extends the property-predicting coverage to all the orbital symmetry for both ground and excited states. SY-GNN shows excellent performance in predicting both the absolute and relative of R and K spaces quantities. Besides the numerical properties, SY-GNN also can predict the orbitals distributions in real space, providing the active regions of chemical reactions. We believe the symmetry endorsed deep learning scheme covers the significant physics inside and is essential for the application of neural networks in QC and many other research fields in the future.
Recomputation algorithms collectively refer to a family of methods that aims to reduce the memory consumption of the backpropagation by selectively discarding the intermediate results of the forward propagation and recomputing the discarded results as needed. In this paper, we will propose a novel and efficient recomputation method that can be applied to a wider range of neural nets than previous methods. We use the language of graph theory to formalize the general recomputation problem of minimizing the computational overhead under a fixed memory budget constraint, and provide a dynamic programming solution to the problem. Our method can reduce the peak memory consumption on various benchmark networks by 36%~81%, which outperforms the reduction achieved by other methods.
We show a correspondence between simple continued fraction expansions of irrational numbers and irreducible permutative representations of the Cuntz algebra ${\cal O}_{\infty}$. With respect to the correspondence, it is shown that the equivalence of real numbers with respect to modular transformations is equivalent to the unitary equivalence of representations. Furthermore, we show that quadratic irrationals are related to irreducible permutative representations of ${\cal O}_{\infty}$ with a cycle.
Adversarial attacks on deep neural networks (DNNs) have been found for several years. However, the existing adversarial attacks have high success rates only when the information of the victim DNN is well-known or could be estimated by the structure similarity or massive queries. In this paper, we propose to Attack on Attention (AoA), a semantic property commonly shared by DNNs. AoA enjoys a significant increase in transferability when the traditional cross entropy loss is replaced with the attention loss. Since AoA alters the loss function only, it could be easily combined with other transferability-enhancement techniques and then achieve SOTA performance. We apply AoA to generate 50000 adversarial samples from ImageNet validation set to defeat many neural networks, and thus name the dataset as DAmageNet. 13 well-trained DNNs are tested on DAmageNet, and all of them have an error rate over 85%. Even with defenses or adversarial training, most models still maintain an error rate over 70% on DAmageNet. DAmageNet is the first universal adversarial dataset. It could be downloaded freely and serve as a benchmark for robustness testing and adversarial training.
We study the asymptotic behavior of solutions to the Vlasov equation in the presence of a strong external magnetic field. In particular we provide a mathematically rigorous derivation of the guiding-center approximation in the general three dimensional setting under the action of large inhomogeneous magnetic fields. First order corrections are computed and justified as well, including electric cross field, magnetic gradient and magnetic curvature drifts. We also treat long time behaviors on two specific examples, the two dimensional case in carte-sian coordinates and a poloidal axi-symmetric geometry, the former for expository purposes. Algebraic manipulations that underlie concrete computations make the most of the linearity of the stiffest part of the system of characteristics instead of relying on any particular variational structure.
The effectiveness of various dilution schemes in the evaluation of baryonic two-point functions is compared. The error of a representative set of observables as a function of the number of Dirac matrix inversions is used as a basis for comparison. To achieve an equivalent reduction in error, we demonstrate that an increase in the number of dilution projectors on a single noise source usually requires fewer inversions than the use of multiple noise sources. This exploratory study was performed on 100 quenched gauge configurations and will be applied to the calculation of low-lying hadron spectra.
Poor packing missing usb charging cable. Product arrived in very damaged box with no outside packaging. I Original product packaging box is very thin cardboard that should have never been shipped that way. It was taped together in several places which immediately told me something would go wrong and in fact it did, the charging cable is missing for the USB charger. The item is now useless and a very expensive caddy. I can’t review the charging capability. I can say it is cheaply made and I would have preferred it to be all one color. I also would have added another tablet slot. Most households have at least one other tablet so another slot would have made sense. The phone slots are just barely big enough for an 6plus sized phone. I do like that there is an extra compartment for any accessories or keys etc. It would have been nice to have one more slot from the extra compartment so you charge other small items like iPhone watch.
Great product, but check the listings and buy the one with 2 adapters included Speaker is outstanding! Only negative is the purchasing options - if you look at ALL of the listings for the product, there is an option to purchase the unit with 2 adapters for $1 more. If you don’t notice that when ordering, the 2nd power adapter will cost you $15
Zombie Nation 2004 R<br /><br />Hey, I was bored. I looked in my Comcastic little box to find a movie to watch. Zombie Nation? Hey, I love zombie movies. Says the filmmaker has some sort of cult following in the description. Funny how it doesn't warn me not to watch this film. I could've used that advice.<br /><br />Zombie Nation is just like Troll 2 in that it's completely misnamed. It has little (if anything, depending on your point of view) to do with zombies, and takes place all within one city. This film revolves around a crooked cop, who acts as badly as possible (he has to be trying to suck this much), while he arrests women for trivial bullshit and then kills them. Yup, he's a serial killer cop. Not only is this film flawed in thinking that it's a zombie flick, it also gets its serial killer facts completely wrong. Serial killers enjoy killing, they live for it and they get down and personal with it. This guy knocks out the women, and injects them with some poison. He doesn't even have sex with the corpse or dismember it. Talk about boring! Eventually, one of the whopping five women he kills has Voodoo protection done to her and for no apparent reason, all five come back to life and head off to kill this guy. They were all buried or tossed into the ocean, but you wouldn't know it buy the sharp clean clothes they're all wearing. The women then act very poorly and take their revenge. Oh yay.<br /><br />This film was crap in every category. Crap acting, crap writing, crappier sets, and crappier make-up effects. The women don't look zombie-like, unless you count really dark make-up around the eyes to be the de facto definition of what makes a zombie. They can all talk, behave, think, and act perfectly human. The gore is weak compared to even many PG-13 films and the nudity is beyond brief. You see glimpse of breasts in the opening sequence... Then the exact same breasts later! Go figure. Guess only one actress was willing to go topless for this trite. The police station is so badly constructed that you can see where they stopped painting the walls of the warehouse they're obviously filming in. You can see the pipes and the bad lighting and the overly sparse set-up and even, unless you are blind, you can see the director failing. Steer clear, it's a waste of time.<br /><br />1/10
The author in $($On the order of Schur multiplier of non-abelian $p$-groups. J. Algebra (2009).322: 4479--4482$)$ showed that for any $p$-group $G$ of order $p^n$ there exists a nonnegative integer $s(G)$ such that the order of Schur multiplier of $G$ is equal to $p^{\f{1}{2}(n-1)(n-2)+1-s(G)}$. Furthermore, he characterized the structure of all non-abelian $p$-groups $G$ when $s(G)=0$. The present paper is devoted to characterization of all $p$-groups when $s(G)=2$.
Disappointed I love what this product is suppose to offer but falls short. While it does hold my phone (iPhone X Max) in the cradle while driving and going over bumps in the road. (important) but it with each bump it chirps as if it quits charging then chirps again to start charging. The buttons to open the side arms is very awkward and behind the phone. Therefore only 3 stars.
A relativistic version of the effective charge model for computation of observable characteristics of multi-electron atoms and ions is developed. A complete and orthogonal Dirac hydrogen basis set, depending on one parameter -- effective nuclear charge $Z^{*}$ -- identical for all single-electron wave functions of a given atom or ion, is employed for the construction of the secondary-quantized representation. The effective charge is uniquely determined by the charge of the nucleus and a set of electron occupation numbers for a given state. We thoroughly study the accuracy of the leading-order approximation for the total binding energy and demonstrate that it is independent of the number of electrons of a multi-electron atom. In addition, it is shown that the fully analytical leading-order approximation is especially suited for the description of highly charged ions since our wave functions are almost coincident with the Dirac-Hartree-Fock ones for the complete spectrum. Finally, we evaluate various atomic characteristics, such as scattering factors and photoionization cross-sections, and thus envisage that the effective charge model can replace other models of comparable complexity, such as the Thomas-Fermi-Dirac model for all applications where it is still utilized.
Mixed reality (MR) ethics occupies a space that intersects with web ethics, emerging tech ethics, healthcare ethics and product ethics (among others). This paper focuses on how we can build an immersive web that encourages ethical development and usage. The technology is beyond emerging (footnote: generally, the ethics of emerging technologies are focused on ethical assessments of research and innovation), but not quite entrenched. We're still in a position to intervene in the development process, instead of attempting to retrofit ethical decisions into an established design. While we have a wider range of data to analyze than most emerging technologies, we're still in a much more speculative state than entrenched technologies. This space is a challenge and an opportunity.
THE ZOMBIE CHRONICLES <br /><br />Aspect ratio: 1.33:1 (Nu-View 3-D)<br /><br />Sound format: Mono<br /><br />Whilst searching for a (literal) ghost town in the middle of nowhere, a young reporter (Emmy Smith) picks up a grizzled hitchhiker (Joseph Haggerty) who tells her two stories involving flesh-eating zombies reputed to haunt the area.<br /><br />An ABSOLUTE waste of time, hobbled from the outset by Haggerty's painfully amateurish performance in a key role. Worse still, the two stories which make up the bulk of the running time are utterly routine, made worse by indifferent performances and lackluster direction by Brad Sykes, previously responsible for the likes of CAMP BLOOD (1999). This isn't a 'fun' movie in the sense that Ed Wood's movies are 'fun' (he, at least, believed in what he was doing and was sincere in his efforts, despite a lack of talent); Sykes' home-made movies are, in fact, aggravating, boring and almost completely devoid of any redeeming virtue, and most viewers will feel justifiably angry and cheated by such unimaginative, badly-conceived junk. The 3-D format is utterly wasted here.
Excitation energies of light-emitting organic conjugated polymers have been investigated with time-dependent density functional theory (TDDFT) within the adiabatic approximation for the dynamical exchange-correlation potential. Our calculations show that the accuracy of the calculated TDDFT excitation energies largely depends upon the accuracy of the dihedral angle obtained by the geometry optimization on ground-state DFT methods. We find that, when the DFT torsional dihedral angles between two adjacent phenyl rings are close to the experimental dihedral angles, the TDDFT excitation energies agree fairly well with experimental values. Further study shows that, while hybrid density functionals can correctly respect the thumb rule between singlet-singlet and singlet-triplet excitation energies, semilocal functionals do not, suggesting inadequacy of the semilocal functionals in predicting triplet excitation energies of conjugated polymers.
In this work we show how a double-cover (DC) extension of the Cachazo, He and Yuan formalism (CHY) can be used to provide a new realization for the factorization of the amplitudes involving gluons and scalar fields. First, we propose a graphic representation for a color-ordered Yang-Mills (YM) and special Yang-Mills-Scalar (YMS) amplitudes within the scattering equation formalism. Using the DC prescription, we are able to obtain an algorithm (integration-rules) which decomposes amplitudes in terms of three-point building-blocks. It is important to remark that the pole structure of this method is totally different to ordinary factorization (which is a consequence of the scattering equations). Finally, as a byproduct, we show that the soft limit in the CHY approach, at leading order, becomes trivial by using the technology described in this paper.
We define higher quantum Airy structures as generalizations of the Kontsevich-Soibelman quantum Airy structures by allowing differential operators of arbitrary order (instead of only quadratic). We construct many classes of examples of higher quantum Airy structures as modules of $\mathcal{W}(\mathfrak{g})$ algebras at self-dual level, with $\mathfrak{g}= \mathfrak{gl}_{N+1}$, $\mathfrak{so}_{2 N }$ or $\mathfrak{e}_N$. We discuss their enumerative geometric meaning in the context of (open and closed) intersection theory of the moduli space of curves and its variants. Some of these $\mathcal{W}$ constraints have already appeared in the literature, but we find many new ones. For $\mathfrak{gl}_{N+1}$ our result hinges on the description of previously unnoticed Lie subalgebras of the algebra of modes. As a consequence, we obtain a simple characterization of the spectral curves (with arbitrary ramification) for which the Bouchard-Eynard topological recursion gives symmetric $\omega_{g,n}$s and is thus well defined. For all such cases, we show that the topological recursion is equivalent to $\mathcal{W}(\mathfrak{gl})$ constraints realized as higher quantum Airy structures, and obtain a Givental-like decomposition for the corresponding partition functions.
False Flag. That is the narrative you are going for? From an agency that has been called internal by other agencies Trumpland. But it was just Comey being a big old False Flag Plant. Yeah that is some long game thinking right there. Obama appoints Comey. Either super genius levels of planning or super stupid, those that hate him can't decide.
Start with 1/2 scoop for a while or you may get the toots I like that this powder has no flavor and can be mixed in to soup or savory dishes just as easily as I can mix it in to my morning oatmeal. I have also struggled with finding a protein powder with no artificial sweetener or stevia in it. This fit those requirements and I wanted the collagen because I have autoimmune and osteoarthritis. Supposedly the collagen will help with that but after 3 weeks of using it, I can’t tell a significant difference. Part of that is because I can only use 1/2 scoop at a time or I get the toots. I had read reviews about others experiencing that and considering that this powder is a derivative of cows and I don’t eat beef, I was cautious right from the start. I will use the remainder of the container but I will also look for a replacement due to the fact that there is only 10g protein per scoop. So since I’m only able to do 1/2 scoop at a time, it’s really only adding 5g protein
We consider the Polyakov Nambu Jona Lasinio model with three massless quarks at high density and moderate temperature in the superconductive color flavor locking phase. We compute the critical temperature $T_c$ as a function of the baryonic chemical potential for the phase transition from the superconductive state to the normal phase. We find that $T_c$ is higher by a factor 1.5 -2 in comparison to the model containing no Polyakov loop. We also compute the specific heat $C_v$ near the second order phase transition and we show that the inclusion of the Polyakov loop does not change the value of the critical exponent.
Don't expect good quality I had hoped this product would at the very least look nice. Unfortunately, I was wrong. It has the potential to be a good product but when predrilled holes don't match and it tilts back and to the left I can't give it a good rating. Very disappointing. d holes don't match up,
We introduce vector space norms associated to the Mahler measure by using the L^p norm versions of the Weil height recently introduced by Allcock and Vaaler. In order to do this, we determine orthogonal decompositions of the space of algebraic numbers modulo torsion by Galois field and degree. We formulate L^p Lehmer conjectures involving lower bounds on these norms and prove that these new conjectures are equivalent to their classical counterparts, specifically, the classical Lehmer conjecture in the p = 1 case and the Schinzel-Zassenhaus conjecture in the p = infinity case.
Certain oscillatory features in the primordial scalar power spectrum are known to provide a better fit to the outliers in the cosmic microwave background data near the multipole moments of $\ell=22$ and 40. These features are usually generated by introducing a step in the popular, quadratic potential describing the canonical scalar field. Such a model will be ruled out, if the tensors remain undetected at a level corresponding to a tensor-to-scalar ratio of, say, $r\simeq 0.1$. In this work, in addition to the popular quadratic potential, we investigate the effects of the step in a small field model and a tachyon model. With possible applications to future datasets (such as PLANCK) in mind, we evaluate the tensor power spectrum exactly, and include its contribution in our analysis. We compare the models with the WMAP (five as well as seven-year), the QUaD and the ACBAR data. As expected, a step at a particular location and of a suitable magnitude and width is found to improve the fit to the outliers (near $\ell=22$ and 40) in all these cases. We point out that, if the tensors prove to be small (say, $r\lesssim 0.01$), the quadratic potential and the tachyon model will cease to be viable, and more attention will need to be paid to examples such as the small field models.
An increasing number of proteins with intrinsically disordered domains have been shown to phase separate in buffer to form liquid-like phases. These protein condensates serve as simple models for the investigation of the more complex membrane-less organelles in cells. To understand the function of such proteins in cells, the material properties of the condensates they form are important. However, these material properties are not well understood. Here, we develop a novel method based on optical traps to study the frequency-dependent rheology and the surface tension of PGL-3 condensates as a function of salt concentration. We find that PGL-3 droplets are predominantly viscous but also exhibit elastic properties. As the salt concentration is reduced, their elastic modulus, viscosity and surface tension increase. Our findings show that salt concentration has a strong influence on the rheology and dynamics of protein condensates suggesting an important role of electrostatic interactions for their material properties.
Very pretty, and I was hoping this would fit well Very pretty, and I was hoping this would fit well, but it did not. I have a short waist, curvey, and the sides of this corset were too high cutting into the under arm, even after carefully measuring before ordering. Shame, as it is beautiful fabric and is made well. Refund took along time.
Having lived in the 2 municipalities of Greater Vancouver I can readily imagine that many, many crimes are not reported. Why bother? The RCMP is so politicized, it is not humorous at all. Or it is so stretched, that the RCMP cannot afford to send officers to an active B&E conducted with a stolen vehicle........ Just to name one of many, many examples. Besides, the RCMP has the implicit mandate of protecting budget-generous politicians who get drunk, run red lights and hit others.
Warning: contains a spoiler. Corny plot and in many cases terrible acting. Fontaine is great, but some others, particularly Richard Ney, Ivy's husband, are exceedingly wooden. Ney lies in bed, dying of arsenical poisoning, with every hair in place. Yet the movie is so juicy and so suspenseful. More faithful to the book than most movies of its era. Casting Joan Fontaine as a poisoner (and an adulteress, which was just as shocking then - I'm not kidding, kids) was a masterful stroke. She's just her usual Joan Fontainey self. As murderers were supposed to, she dies by falling "feet foremost through the floor into an empty space."
Hard to solder to Perhaps it’s because I had new solder, but I had a great deal of difficulty soldering to these pads. I think the pads didn’t heat up readily, making it difficult to get the solder to flow in to. In the end, I used way more solder than I would use normally, and my joints are all blobby. It does cut well and I like the arrangement of the rails.
The distribution of eccentricities e of extra-solar planets with semi-major axes a > 0.2 AU is very uniform, and values for e are generally large. For a < 0.2 AU, eccentricities are much smaller (most e < 0.2), a characteristic widely attributed to damping by tides after the planets formed and the protoplanetary gas disk dissipated. We have integrated the classical coupled tidal evolution equations for e and a backward in time over the estimated age of each planet, and confirmed that the distribution of initial e values of close-in planets matches that of the general population for reasonable tidal dissipation values Q, with the best fits for stellar and planetary Q being ~ 10^5.5 and ~ 10^6.5 respectively. The current small values of a were only reached gradually due to tides over the lifetimes of the planets, i.e., the earlier gas disk migration did not bring all planets to their current orbits. As the orbits tidally evolved, there was substantial tidal heating within the planets. The past tidal heating of each planet may have contributed significantly to the thermal budget that governed the planet's physical properties, including its radius, which in many cases may be measured by observing transit events. Here we also compute the plausible heating histories for a few planets with anomalously large measured radii, including HD 209458 b. We show that they may have undergone substantial tidal heating during the past billion years, perhaps enough to explain their large radii. Theoretical models of exoplanet interiors and the corresponding radii should include the role of large and time-variable tidal heating. Our results may have important implications for planet formation models, physical models of "hot Jupiters", and the success of transit surveys.

I was not very pleased with this purchase since I had wanted to git this to someone, and the package arrived a month after track the package said it would.
Kate is a jaded young woman who has trouble meeting and dating guys. Throughout the movie, you get to meet several of her loser boyfriends. And throughout the movie, you are subjected to Kate's cynical negative outlook on love and relationships. This negative viewpoint is continued throughout and presented as Ultimate Truth. I had a real problem with this. Why would anyone want to be taught about love, life, and dating from someone who is obviously so messed up? It would work if that was the joke, but it is not. For the jokes in the movie (which are neither funny nor original) to work at all, you have to believe what Kate is saying: that all relationships inevitably end up with bad or no sex, that the highest level a relationship can evolve to is when you are able to fart in front of your partner... You get the idea.<br /><br />There is no movie in recent memory that comes close to upsetting the stomach as much as Love & Sex. Why did the filmmakers waste their time on such trash? Every joke in Love & Sex is something that I have experienced in another movie or in my own life. There is NOTHING original or creative about the story, the production, or the style. It is cynical, dumb and pointless. Mind numbing!
The relationship (guanxi 关系） that was developed by Prime Minister Justin Trudeau between Premier Li Keqiang was astounding in its complexity and efficacy. Their families were able to enjoy each other's company. This is the way one should relate to the Chinese on all levels. Trudeau has been to China many times. Xiao Tudou - 小土豆 - Small Potato is a name that endears him to the Chinese. When people insult the prime minister by making fun of this lovely name, they insult the Chinese. Why? Because it's a form of bullying. Anyone who really knows anything substantial about the Chinese as opposed to ephemeral ranting knows this is true.
I once made a "on the phone" gesture by putting my spread fingers to my head when a driver was looking at her phone rather than noticing the left turn signal was green. As she did a U-turn she leaned over across the passenger seat (I was standing on the corner) to flip me off. Of course, one hand had the cell phone and the other was now flipping me off, so her driving wheel started spinning freely and her SUV straightened out in the middle of the turn. I loved the look of shock as her vehicle careened around before she got it back under control!
We study a holographic gauge theory dual to the D3/D5 intersection. We consider a pure gauge B-field flux through the internal two-sphere wrapped by the probe D5--brane, which corresponds to a non-commutative configuration of adjoint scalars. There is a domain wall separating the theory into regions with different ranks of the adjoint group. At zero temperature the theory is supersymmetric and at finite temperature there is a critical point of a second order phase transition. We study the corresponding critical exponents and find that the second derivatives of the free energy, with respect to the bare mass and the magnetic field, diverge with a critical exponent of -2/3.
The nonlinear properties of quasiperiodic photonic crystals based on the Thue-Morse sequence are investigated. The intrinsic spatial asymmetry of these one-dimensional structures for odd generation numbers results in bistability thresholds which are sensitive to the propagation direction. Along with resonances of perfect transmission, this feature allows to achieve strongly non-reciprocal propagation and to create an all-optical diode. The salient qualitative features of such optical diode action is readily explained through a simple coupled resonator model. The efficiency of a passive scheme, which does not necessitate of an additional short pump signal, is compared to an active scheme, where such a signal is required.
The most satisfying element about "Dan in Real Life" is that the relationship between Dan (Steve Carell) and Marie (Juliette Binoche) makes sense and is beautifully realistic. The casting of Oscar-winner Juliette Binoche as Dan's love interest was a superb decision; she is exceptionally talented, intelligent, naturally attractive and, thank goodness, appropriately aged for the part! Had this movie been made with Jessica Alba or Scarlett Johansson, it would have been a disaster.<br /><br />Another wonderful aspect about "Dan in Real Life" is that it is a perfect film for adults who are interested in a mature comedy that leaves out the three pillars of the "frat pack" formula: dumb chicks, chauvinistic guys, and sleazy jokes. "Dan in Real Life" is witty and has fun, intelligent laughs throughout. Whereas other comedies incorporate or are almost entirely based on jokes that shock the audience into laughing, the jokes from "Dan in Real Life" are more natural and clever, and involve some thinking on the part of the audience.<br /><br />My only problem with "Dan in Real Life" is that the rebellious, middle daughter is played too outrageously by actress Brittany Robertson. It's difficult to say if this was a personal choice on her part or a choice by the director. Either way, her character is unrealistic and annoying. But, this is only a minor flaw in the film, and does not take away from the story as a whole.<br /><br />All in all, "Dan in Real Life" is a great film, a fantastic escape from the redundancy of offensive and dumbed-down comedies. The quality of the writing, directing, acting, and (especially) cinematography is excellent. It is simply a beautiful, light-hearted comedy.
One of the more satisfying Western all'italiana, Johnny Yuma has the freshness of many WAI made during the heyday of the genre and is highly recommended for fans of the genre or offbeat, intelligent cinema.<br /><br />Johnny Yuma is, in most respects, not terribly original, but this actually does not count against it. The success of a genre film depends on how well it meets the audience's expectations as well as provides surprising variations on these expected elements. Earlier, pleasing experiences are recreated but with subtle (or major) twist that provide continuing interest. The quality of the execution is also, obviously, important. A tired retread will be less successful than a sincere attempt to entertain or move the audience.<br /><br />Given these criteria, Johnny Yuma succeeds. There are numerous reprises of elements from earlier films. The setting is the brutal, twisted semi-feudal twilight world of shared by many of the best "Gothic family" westerns made 1964-1968 such as Tempo di massacre (1966). The plot is a combination of the basic Fistful of Dollars (1964) plot and the Ringo films, a fact not surprising as screenwriter Fendiando di Leo was involved in both. Di Leo was one of the best screenwriters in the popular cinema coming out of Cinecitta in the 1960s-70s and his work helped provide much of the thematic continuities and coherency to the genre (Along with a couple of other personalities in a few distinct circles of actors, directors, and screenwriters). In the FOD plot, the protagonist arrives in town, stirs up a tense situation, then undergoes a near-death followed by a resurrection (in some films, like Quella sporca storia nel west (1968) it is quite literally a crucifixion). The Catholic undertone to the narrative and the symbolism is intriguing, especially given the implicit populist/explicit socialist leanings of the filmmakers and their films. The Ringo plot, developed more fully by screenwriter Ernesto Gastaldi in a series of films starring Guliano Gemma, a egoistic protagonist chooses the interest of a community over his own through the medium of a relationship with a member of that community (with a healthy dash ironic uncertainty).<br /><br />The relationship between Carradine and Johnny is clearly based on that of Manco/Mortimer from a Fistful of Dollar (1965). The two scene of the exchange of the gun belts provides a clever dialog and understanding between the two. Numerous films, including Da uomo a uomo (1968) or even El Chuncho, quién sabe? (1967), use this relationship between an older and younger man (father/son, older/younger brother, Anglo adviser/adversary and peasant revolutionary) as a central dynamic to the plot.<br /><br />Additionally, there is the focus on deception and misdirection, mazes and mirrors, that recur throughout the best early WAI. The canons and pueblos of Almeria become literal mazes through which protagonist and antagonist play shifting games of cat and mouse.<br /><br />What distinguishes Johnny Yuma from other WAI is the quality of director Romolo Guerriri's use of visual/psychological space together arrangement with the script's intelligent mechanisms to forward the plot. Dialogue was never very important to the WAI and often absurdly unintelligible (thought there are exceptions, such as the cynical commentaries in Django (1966) or Faccia a faccia (1967).<br /><br />Psychological depth of character is created almost entirely through iconic imagery, it's juxtapositions, and it's description of the overall narrative situation. See how the presence of the deadly Samantha is felt during the beating scene watching from the roof or from the background of the action. Or how Johnny strips Samantha and Pedro of their security and confidence in their power through his stealthy invasions of their ranch, hotel, even bedroom (this, again, is a theme from FOD). Finally, note how there is a focus on the search for information. Like many elements, this is borrowed from FOD which was ultimately based on the hard-boiled mystery novel Red Harvest. It is through incidental contacts, wanted posters, overheard conversations, glances out of windows, watches left in the dust, or mistaken identities and movements through the ripples created by the actions of Pedro and Samantha within this surreal and absurd reality that the narrative tacks forward to it's conclusion.<br /><br />The movie was notable in it's time for what were perceived of as excesses in violence. Of course, these films were hardly more violent than many American westerns. What was different was the psychological intensity of the violence and the causes to which it was attributed, which is to say that it was not the violence but it's meaning that had changed. Johnny Yuma is distinct and interesting in it's use and portrayal of violence and this is another interesting aspect of the film.<br /><br />What I personally find most interesting about most of this genre is the link it provides to the anonymous, nameless audiences in Italy and Spain to whom these recurrent narratives held some significance and interest. The artifact may have no intrinsic worth in and of itself some flint debitage from a prehistoric site, a shard of cruse pottery, or a moldering piece of leather and rusted metal but it is reference to some nameless presence, lives, that were significant simply because they existed. While Johnny Yuma has intrinsic worth, much of it's interest for me derives from this connection and mystery.<br /><br />Top spaghetti western list http://imdb.com/mymovies/list?l=21849907<br /><br />Average SWs http://imdb.com/mymovies/list?l=21849889<br /><br />For fanatics only (bottom of the barrel) http://imdb.com/mymovies/list?l=21849890
In the context of individual-level causal inference, we study the problem of predicting whether someone will respond or not to a treatment based on their features and past examples of features, treatment indicator (e.g., drug/no drug), and a binary outcome (e.g., recovery from disease). As a classification task, the problem is made difficult by not knowing the example outcomes under the opposite treatment indicators. We assume the effect is monotonic, as in advertising's effect on a purchase or bail-setting's effect on reappearance in court: either it would have happened regardless of treatment, not happened regardless, or happened only depending on exposure to treatment. Predicting whether the latter is latently the case is our focus. While previous work focuses on conditional average treatment effect estimation, formulating the problem as a classification task rather than an estimation task allows us to develop new tools more suited to this problem. By leveraging monotonicity, we develop new discriminative and generative algorithms for the responder-classification problem. We explore and discuss connections to corrupted data and policy learning. We provide an empirical study with both synthetic and real datasets to compare these specialized algorithms to standard benchmarks.
We analyse type IIA Calabi-Yau orientifolds with backgroud fluxes, taking into account the effect of perturbative $\alpha'$-corrections. In particular, we consider the $\alpha'$-corrections that modify the metrics in the K\"ahler sector of the compactification. As it has been argued in the literature, including such $\alpha'$-corrections allows to construct the mirror duals of type IIB Calabi-Yau flux compactifications, in which the effect of flux backreaction is under control. We compute the $\alpha'$-corrected scalar potential generated by the presence of RR and NS fluxes, and reformulate it as a bilinear of the flux-axion polynomials invariant under the discrete shift symmetries of the compactification. The use of such invariants allows to express in a compact and simple manner the conditions for Minkowski and AdS flux vacua, and to extract the effect of $\alpha'$-corrections on them.
The goal of this paper is to provide a numerically fast and stable description for the microlensing amplification of an extended source (either uniform or limb-darkened) that holds in any amplification regime. We show that our method of evaluating the amplification can be implemented into a light-curve fitting routine using the Levenberg-Marquardt algorithm. We compare the accuracy and computation times to previous methods that either work in the high-amplification regime only, or require special treatments due to the singularity of elliptic integrals. In addition, we also provide the equations including finite lens effects in microlensing light curves. We apply our methods to the MACHO-1995-BLG-30 and the OGLE-2003-BLG-262 events and obtain results consistent to former studies. We derive an upper limit for the OGLE-2003-BLG-262 event lens size. We conclude that our method allows to simultaneously search for point-source and finite-source microlensing events in future large area microlensing surveys in a fast manner.
In a previous paper [Phys. Rev. D 97, 104044 (2018)] we pointed out some shortcomings of the standard approach to chameleon theories consisting in treating the small bodies used to test the weak equivalence principle (WEP) as test particles, whose presence do not modify the chameleon field configuration. In that paper we developed an alternative method to determine the relevant field configuration which takes into account the influence of both test and source bodies, and computed the chamaleon mediated force. Relying on that analysis we showed that the effective acceleration of test bodies is composition dependent even when the model is based on universal couplings. In this paper, we improve our method by using a more suitable approximation for the effective chameleon potential in situations where the bodies are in the so-called "thick shell regime". We then find new and more restrictive bounds on the model' s parametres by confronting the new theoretical predictions with the empirical bounds on E\"otv\"os parameter comming from the lunar laser ranging experiments.
Recently, Point of interest (POI) recommendation has gained ever-increasing importance in various Location-Based Social Networks (LBSNs). With the recent advances of neural models, much work has sought to leverage neural networks to learn neural embeddings in a pre-training phase that achieve an improved representation of POIs and consequently a better recommendation. However, previous studies fail to capture crucial information about POIs such as categorical information. In this paper, we propose a novel neural model that generates a POI embedding incorporating sequential and categorical information from POIs. Our model consists of a check-in module and a category module. The check-in module captures the geographical influence of POIs derived from the sequence of users' check-ins, while the category module captures the characteristics of POIs derived from the category information. To validate the efficacy of the model, we experimented with two large-scale LBSN datasets. Our experimental results demonstrate that our approach significantly outperforms state-of-the-art POI recommendation methods.
I should have been charged less for something that looks used It came in fast and the shipping box was in mint condition but for the product I ordered that’s a different story. When ordering I was hoping for by ordering something new the packaging would be in great or even better mint condition for being a collector of sorts but it looks like it took an old school WWF Attitude era beat down, very disappointed. The figure it’s self looks excellent and in good condition, in the end I’d rather been told upfront that it was in a damaged package and it was at least $6 less than what I payed.
In a smooth semiparametric estimation problem, the marginal posterior for the parameter of interest is expected to be asymptotically normal and satisfy frequentist criteria of optimality if the model is endowed with a suitable prior. It is shown that, under certain straightforward and interpretable conditions, the assertion of Le Cam's acclaimed, but strictly parametric, Bernstein-von Mises theorem [Univ. California Publ. Statist. 1 (1953) 277-329] holds in the semiparametric situation as well. As a consequence, Bayesian point-estimators achieve efficiency, for example, in the sense of H\'{a}jek's convolution theorem [Z. Wahrsch. Verw. Gebiete 14 (1970) 323-330]. The model is required to satisfy differentiability and metric entropy conditions, while the nuisance prior must assign nonzero mass to certain Kullback-Leibler neighborhoods [Ghosal, Ghosh and van der Vaart Ann. Statist. 28 (2000) 500-531]. In addition, the marginal posterior is required to converge at parametric rate, which appears to be the most stringent condition in examples. The results are applied to estimation of the linear coefficient in partial linear regression, with a Gaussian prior on a smoothness class for the nuisance.
Anisotropy of atomic states is characterized by population differences and coherences between Zeeman sublevels. It can be efficiently created and probed via resonant interactions with light, the technique which is at the heart of modern atomic clocks and magnetometers. Recently, nonlinear magneto-optical techniques have been developed for selective production and detection of higher polarization moments, hexadecapole and hexacontatetrapole, in the ground states of the alkali atoms. Extension of these techniques into the range of geomagnetic fields is important for practical applications. This is because hexadecapole polarization corresponding to the $\Delta M=4$ Zeeman coherence, with maximum possible $\Delta M$ for electronic angular momentum $J=1/2$ and nuclear spin $I=3/2$, is insensitive to the nonlinear Zeeman effect (NLZ). This is of particular interest because NLZ normally leads to resonance splitting and systematic errors in atomic magnetometers. However, optical signals due to the hexadecapole moment decline sharply as a function of magnetic field. We report a novel method that allows selective creation of a macroscopic long-lived ground-state hexadecapole polarization. The immunity of the hexadecapole signal to NLZ is demonstrated with F=2 $^{87}$Rb atoms at Earth's field.
Most people don't even know directional drilling exists. Let alone know that it has no impact at all to the ground thousands of feet above it. I do give you credit for knowing about directional drilling though. Nonetheless, the headline is still written to leave a gross misrepesentation. For instance, a simply "2 miles underneath HS" would leave a much less dire (and far more accurate) impression.
The presence of a body in an orbit around a close eclipsing binary star manifests itself through the light time effect influencing the observed times of eclipses as the close binary and the circumbinary companion both move around the common centre of mass. This fact combined with the periodicity with which the eclipses occur can be used to detect the companion. Given a sufficient precision of the times of eclipses, the eclipse timing can be employed to detect substellar or even planetary mass companions. The main goal of the paper is to investigate the potential of the photometry based eclipse timing of binary stars as a method of detecting circumbinary planets. In the models we assume that the companion orbits a binary star in a circular Keplerian orbit. We analyze both the space and ground based photometry cases. In particular, we study the usefulness of the on-going COROT and Kepler missions in detecting circumbinary planets. We also explore the relations binding the planet discovery space with the physical parameters of the binaries and the geometrical parameters of their light curves. We carry out detailed numerical simulations of the eclipse timing by employing a relatively realistic model of the light curves of eclipsing binary stars. We study the influence of the white and red photometric noises on the timing precision. We determine the sensitivity of the eclipse timing technique to circumbinary planets for the ground and space based photometric observations. We provide suggestions for the best targets, observing strategies and instruments for the eclipse timing method. Finally, we compare the eclipse timing as a planet detection method with the radial velocities and astrometry.
Best customer care EVER I must say that this company is the best I've dealt with! The product I purchased was not as expected for my needs, not only did the reach out and offer a better heating pad but once they found out I had already purchased another product, they offered a full refund. This is the best customer service I have ever received and I highly recommend using them. If I'm ever in need of another, I will be going through them ONLY.
Enabled by the Fermi Large Area Telescope, we now know young and recycled pulsars fill the gamma-ray sky, and we are beginning to understand their emission mechanism and their distribution throughout the Galaxy. However, key questions remain: Is there a large population of pulsars near the Galactic center? Why do the most energetic pulsars shine so brightly in MeV gamma rays but not always at GeV energies? What is the source and nature of the pair plasma in pulsar magnetospheres, and what role does the polar cap accelerator play? Addressing these questions calls for a sensitive, wide-field MeV telescope, which can detect the population of MeV-peaked pulsars hinted at by Fermi and hard X-ray telescopes and characterize their spectral shape and polarization.
We prove that the local $\mathbb{A}^1$-degree of a polynomial function at an isolated zero with finite separable residue field is given by the trace of the local $\mathbb{A}^1$-degree over the residue field. This fact was originally suggested by Morel's work on motivic transfers and by Kass and Wickelgren's work on the Scheja-Storch bilinear form. As a corollary, we generalize a result of Kass and Wickelgren's relating the Scheja-Storch form and the local $\mathbb{A}^1$-degree.
The ending of this movie made absolutely NO SENSE. What a waste of 2 perfectly good hours. If you can explain it to me...PLEASE DO. I don't usually consider myself unable to "get" a movie, but this was a classic example for me, so either I'm slower than I think, or this was a REALLY bad movie.
Mobility-on-Demand (MoD) systems require load balancing to maintain consistent service across regions with uneven demand subject to time-varying traffic conditions. The load-balancing objective is to jointly minimize the fraction of lost customer requests due to vehicle unavailability and the fraction of time when vehicles drive empty during load balancing operations. In order to bypass the intractability of a globally optimal solution to this stochastic dynamic optimization problem, we propose a parametric threshold-based control driven by the known relative abundance of vehicles available in and en route to each region. This is still a difficult parametric optimization problem for which one often resorts to trial-and-error methods where multiple sample paths are generated through simulation or from actual data under different parameter settings. In contrast, this paper utilizes concurrent estimation methods to simultaneously construct many sample paths from a single nominal sample path. The performance of the parametric controller for intermediate size systems is compared to that of a simpler single-parameter controller, a state-blind static controller, a policy of no control, and a theoretically-derived lower bound. Simulation results show the value of state information in improving performance.
The gravitational waves (GWs) emitted by inspiraling binary black holes, expected to be detected by the Laser Interferometer Space Antenna (LISA), could be used to determine the luminosity distance to these sources with the unprecedented precision of <~ 1%. We study cosmological parameter constraints from such standard sirens, in the presence of gravitational lensing by large-scale structure. Lensing introduces magnification with a probability distribution function (PDF) whose shape is highly skewed and depends on cosmological parameters. We use Monte-Carlo simulations to generate mock samples of standard sirens, including a small intrinsic scatter, as well as the additional, larger scatter from lensing, in their inferred distances. We derive constraints on cosmological parameters, by simultaneously fitting the mean and the distribution of the residuals on the distance vs redshift (d_L - z) Hubble diagram. We find that for standard sirens at redshift z ~ 1, the sensitivity to a single cosmological parameter, such as the matter density Omega_m, or the dark energy equation of state w, is ~ 50%-80% tighter when the skewed lensing PDF is used, compared to the sensitivity derived from a Gaussian PDF with the same variance. When these two parameters are constrained simultaneously, the skewness yields a further enhanced improvement (by ~ 120%), owing to the correlation between the parameters. The sensitivity to the amplitude of the matter power spectrum, sigma_8 from the cosmological dependence of the PDF alone, however, is ~ 20% worse than that from the Gaussian PDF. At higher redshifts, the PDF resembles a Gaussian more closely, and the effects of the skewness become less prominent. These results highlight the importance of obtaining an accurate and reliable PDF of the lensing convergence, in order to realize the full potential of standard sirens as cosmological probes.
In the near future we will have ground- and space-based telescopes that are designed to observe and characterize Earth-like planets. While attention is focused on exoplanets orbiting main sequence stars, more than 150 exoplanets have already been detected orbiting red giants, opening the intriguing question of what rocky worlds orbiting in the habitable zone of red giants would be like and how to characterize them. We model reflection and emission spectra of Earth-like planets orbiting in the habitable zone of red giant hosts with surface temperatures between 5200 and 3900 K at the Earth-equivalent distance, as well as model planet spectra throughout the evolution of their hosts. We present a high-resolution spectral database of Earth-like planets orbiting in the red giant habitable zone from the visible to infrared, to assess the feasibility of characterizing atmospheric features including biosignatures for such planets with upcoming ground- and space-based telescopes such as the Extremely Large Telescopes and the James Webb Space Telescope.
Proceeded from the gravitation equations proposed by one of authors it was argued in a previous paper that there can exist supermassive compact configurations of degenerated Fermi-gas without events horizon. In the present paper we consider the stability of these objects by method like the one used in the theory of stellar structure. It is shown that the configurations with an adiabatic equation of state with the power 4/3 are stable.
We built an optimal basis of low resolution templates for galaxies over the wavelength range from 0.2 to 10 $\mu$m using a variant of the algorithm presented by Budavari et al. (2000). We derived them using eleven bands of photometry from the NDWFS, FLAMEX, zBo\"otes and IRAC Shallow surveys for 16033 galaxies in the NDWFS Bo\"otes field with spectroscopic redshifts measured by the AGN and Galaxy Evolution Survey. We also developed algorithms to accurately determine photometric redshifts, K corrections and bolometric luminosities using these templates. Our photometric redshifts have an accuracy of $\sigma_z/(1+z) = 0.04$ when clipped to the best 95%. We used these templates to study the spectral type distribution in the field and to estimate luminosity functions of galaxies as a function of redshift and spectral type. In particular, we note that the 5-8$\mu$m color distribution of galaxies is bimodal, much like the optical g--r colors.
Another great musical from Hollywoods Golden Age! I liked this movies story about a trio of friends who are performers at a small nightclub that is far from Broadway and all its glitter. Although not the big time they are very content with their lives and the small club where they perform. Gene Kelly plays the owner of the small club and is also the boyfriend of one of its dancers, Rita Hayworth who happens to garner some attention when she's given an opportunity to be on a cover of a magazine. Trouble begins for Gene Kelly as his girlfriend is now the talk of the town. Phil Silvers plays one of the three friends and does a good job. Of course there is the music and the dancing. One dance performance by Gene Kelly stands out. He is walking along the street at night alone and he see his reflection in a shop window. His reflection soon starts dancing along with him in the streets, great cinematography. Don't miss this one, great entertainment.
The movie opens with Charlie (Jeff Daniels), a business man just finishing his lunch in a neighborhood deli. It appears he doesn't have enough cash to cover the check. Instead of reaching for his plastic, he furtively glances around to see if the coast is clear and ducks out of the place without paying. Unbeknownst to Charlie, "Lulu" (Melanie Griffith) had been observing him from the other side of the deli.<br /><br />"Lulu" is decked out in what passed for cool back in the 1980's with a brunette page-boy cut. She follows him out to let him know that she saw what he did. He tries to deny it but can't escape her accusation. Thinking he's in it, Charlie is surprised when "Lulu" says she doesn't work for the deli and then offers him a ride back to work.<br /><br />When she heads in the opposite direction, thus begins their cavorting across the Middle Atlantic Seaboard.<br /><br />We're supposed to get titillated as thoroughly modern "Lulu" puts straight-laced Charlie into humiliating situations. It's all right when the two consenting adults get a little kinky in a motel room but off-putting when they wriggle out of paying the check at a family-style restaurant. Stealing the labor from hard-working people is not my idea of "wild". Charlie is a jerk.<br /><br />"Lulu" is a loony jerk. She starts to pass off Charlie as her husband. First to her mom (who blithely tolerates the charade) and then at her conveniently timed 10-year high school reunion (an event used later by another too-cool-for-its-own-good movie "Grosse Pointe Blank").<br /><br />The "marriage" comes as a surprise to "Lulu"'s real husband (Ray Liotta)who's just been recently released from prison for armed robbery. Ray gives the two a welcome comeuppance and shows them how nasty crime really is.<br /><br />I can't add any irony by writing that I first watched this by sneaking in the movie theater. No, I don't do that sort of thing. I taped it off of cable TV and assure you I view it strictly in the privacy of my own home.<br /><br />So I got to thinking why I taped it when I don't like it very much and conclude that 20 years ago I was on a reggae kick and the soundtrack of "Something Wild" does prominently feature reggae. The closing credits start with the treat of Sister Carol performing her version of "Wild Thing".
This paper considers the nonparametric regression model with negatively super-additive dependent (NSD) noise and investigates the convergence rates of thresholding estimators. It is shown that the term-by-term thresholding estimator achieves nearly optimal and the block thresholding estimator attains optimal (or nearly optimal) convergence rates over Besov spaces. Additionally, some numerical simulations are implemented to substantiate the validity and adaptivity of the thresholding estimators with the presence of NSD noise.
The effects of flavor mixing in electroweak baryogenesis is investigated in a generalized semiclassical WKB approach. Through calculating the nonadiabatic corrections to the particle currents it is shown that extra CP violation sources arise from the off-diagonal part of the equation of motion of particles moving inside the bubble wall. This type of mixing-induced source is of the first order in derivative expansion of the Higgs condensate, but is oscillation suppressed. The numerical importance of the mixing-induced source is discussed in the Minimal Supersymmetric Standard Model and compared with the source term induced by semiclassical force. It is found that in a large parameter space where oscillation suppression is not strong enough, the mixing-induced source can dominate over that from the semiclassical force.
We present the results of parsec-scale circular polarization (CP) measurements based on VLBA data for a number of radio-bright, core-dominated AGN obtained simultaneously at 15, 22 and 43 GHz. The degrees of CP $m_c$ for the VLBI core region at 15 GHz are similar to values reported earlier at this wavelength, with typical values of a few tenths of a percent.We find that $m_c$ as often rises as falls with increasing frequency between 15 and 22 GHz, while $m_c$ at 43 GHz is in all cases higher than at 22 and 15 GHz. This behaviour seems contrary to expectations, since the degree of CP from both synchrotron radiation and Faraday conversion of linear to circular polarization should {\em decrease} towards higher frequencies if the source is homogeneous. The increase in $m_c$ at 43 GHz may be due to the presence of regions of both positive and negative CP with different frequency dependences on small scales within the core region; alternatively, it may be associated with the intrinsic inhomogeneity of a Blandford-K\"onigl-like jet. In several objects, the detected CO appears to be near, but not coincident with the core, although further observations are needed to confirm this. We find several cases of changes in sign with frequency, most often between 22 and 43 GHz. We find tentative evidence for transverse structure in the CP of 1055+018 and 1334$-$127 that is consistent with their being generated by either the synchrotron mechanism or Faraday conversion in a helical magnetic field. Our results confirm the earlier finding that the sign of the CP at a given observing frequency is generally consistent across epochs separated by several years or more, suggesting stability of the magnetic field orientation in the innermost jets.
Visual Cryptography is a special encryption technique to hide information in images, which divide secret image into multiple layers. Each layer holds some information. The receiver aligns the layers and the secret information is revealed by human vision without any complex computation. The proposed algorithm is for color image, that presents a system which takes four pictures as an input and generates three images which correspond to three of the four input pictures. The decoding requires only selecting some subset of these 3 images, making transparencies of them, and stacking them on top of each other, so the forth picture is reconstructed by printing the three output images onto transparencies and stacking them together. The reconstructed image achieved in same size with original secret image.
We address the challenging issue of how CP violation is realized in higher dimensional gauge theories without higher dimensional elementary scalar fields. In such theories interactions are basically governed by a gauge principle and therefore to get CP violating phases is a non-trivial task. It is demonstrated that CP violation is achieved as the result of compactification of extra dimensions, which is incompatible with the 4-dimensional CP transformation. As a simple example we adopt a 6-dimensional U(1) model compactified on a 2-dimensional orbifold $T^{2}/Z_{4}$. We argue that the 4-dimensional CP transformation is related to the complex structure of the extra space and show how the $Z_{4}$ orbifolding leads to CP violation. We confirm by explicit calculation of the interaction vertices that CP violating phases remain even after the re-phasing of relevant fields. For completeness, we derive a re-phasing invariant CP violating quantity, following a similar argument in the Kobayashi-Maskawa model which led to the Jarlskog parameter. As an example of a CP violating observable we briefly comment on the electric dipole moment of the electron.
