We propose to combine the advantages of graphene, such as easy tunability and long coherence times, with Josephson physics to manufacture qubits. If these qubits are built around a 0 and $\pi$ junction they can be controlled by an external flux. Alternatively, a d-wave Josephson junction can itself be tuned via a gate voltage to create superpositions between macroscopically degenerate states. We show that ferromagnets are not required for realizing $\pi$ junction in graphene, thus considerably simplifying its physical implementation. We demonstrate how one qubit gates, such as arbitrary phase rotations and the exchange gate, can be implemented.
Due to its hereditary nature, genomic data is not only linked to its owner but to that of close relatives as well. As a result, its sensitivity does not really degrade over time; in fact, the relevance of a genomic sequence is likely to be longer than the security provided by encryption. This prompts the need for specialized techniques providing long-term security for genomic data, yet the only available tool for this purpose is GenoGuard (Huang et al., 2015). By relying on Honey Encryption, GenoGuard is secure against an adversary that can brute force all possible keys; i.e., whenever an attacker tries to decrypt using an incorrect password, she will obtain an incorrect but plausible looking decoy sequence. In this paper, we set to analyze the real-world security guarantees provided by GenoGuard; specifically, assess how much more information does access to a ciphertext encrypted using GenoGuard yield, compared to one that was not. Overall, we find that, if the adversary has access to side information in the form of partial information from the target sequence, the use of GenoGuard does appreciably increase her power in determining the rest of the sequence. We show that, in the case of a sequence encrypted using an easily guessable (low-entropy) password, the adversary is able to rule out most decoy sequences, and obtain the target sequence with just 2.5\% of it available as side information. In the case of a harder-to-guess (high-entropy) password, we show that the adversary still obtains, on average, better accuracy in guessing the rest of the target sequences than using state-of-the-art genomic sequence inference methods, obtaining up to 15% improvement in accuracy.
In network tomography, one goal is to identify a small set of failed links in a network, by sending a few packets through the network and seeing which reach their destination. This problem can be seen as a variant of combinatorial group testing, which has been studied before under the moniker "graph-constrained group testing." The main contribution of this work is to show that for most graphs, the "constraints" imposed by the underlying network topology are no constraint at all. That is, the number of tests required to identify the failed links in "graph-constrained" group testing is near-optimal even for the corresponding group testing problem with no graph constraints. Our approach is based on a simple randomized construction of tests, to analyze our construction, we prove new results about the size of giant components in randomly sparsified graphs. Finally, we provide empirical results which suggest that our connected-subgraph tests perform better not just in theory but also in practice, and in particular perform better on a real-world network topology.
Quantum droplets are ultradilute liquid states which emerge from the competitive interplay of two Hamiltonian terms, the mean-field energy and beyond-mean-field correction, in a weakly interacting binary Bose gas. We relate the formation of droplets in symmetric and asymmetric two-component one-dimensional boson systems to the modulational instability of a spatially uniform state driven by the beyond-mean-field term. Asymmetry between the components may be caused by their unequal populations or unequal intra-component interaction strengths. Stability of both symmetric and asymmetric droplets is investigated. Robustness of the symmetric solutions against symmetry-breaking perturbations is confirmed.
What a start to the Will Trent series. I like this series. The main characters are unusual and very damaged from a terrible childhood. Will is an excellent investigator but due to a disability he believes he is illiterate. Slaughter does a very good job showing how people with dyslexia learn ways to hide their limitations. It will be interesting to see how these characters play out in the future. I understand that Slaughter brings some of the characters from the Grant County series to this series. The crimes are brutal. I'm sure this is a good representation of what police come across in their career. The procedural is well done and kept me interested from start to finish. I'm looking forward to reading more of this series soon.
I give this movie a 4 cause I'm a die hard fan of the video game series. the graphics and animation are excellent and its nice to see the whole gang in CG form Sephiroth's still cool<br /><br />now the reasons it only got a 4 well the characters feel like planks of wood with some of the worst voice acting I've ever seen(I've watched epic movie)<br /><br />the movie just seems cloud orientated so much so that it make even the fans embarrassed with cloud this and cloud that. clouds mentioned so much that it make you not want to see him in this movie <br /><br />the villains have the award for the worst villains ever (i was more scared by the wicked witch of the west) <br /><br />all the other characters in this movie are simply put in the movie for a nod to the fans and doesn't take it further then that<br /><br />wtf's with the chilly chally???<br /><br />summary: waited 9 years for this movie and this is what i get a large pointless and boring cut scene i beg the head of square cenix to shoot the man responsible for this burn every copy of the movie and any one involved in it and create a new movie from the ashes's (it would be nice to make the movie in live action and based on the original game)
We present the first study of treating b, c, and s quarks as Dirac fermions in lattice QCD with exact chiral symmetry. For 100 gauge configurations generated with single-plaquette action at beta = 7.2 on the 32^3 x 60 lattice, we compute point-to-point quark propagators for 33 quark masses in the range 0.01 < m_q a < 0.85, and measure the time-correlation function of (pseudo-)scalar, (pseudo-)vector, and tensor mesons, for symmetric and asymmetric quark masses respectively. The lowest-lying mass spectra of mesons with quark contents b_bbar, c_bbar, s_bbar, and c_cbar are determined, together with the pseudoscalar decay constants. Our results are sumarized in Tables 1-5. Furthermore, we also determine the b and c quark masses in the MS_bar scheme, m_b = 4.65(5) GeV, and m_c = 1.16(4) GeV.
I've had a lot of experience with women in Russia, and this movie portrays what a lot of them are like, unfortunately. They are very cunning, ruthless, and greedy, as well as highly unfair. From the robotic sex, the hustling for gifts, to the lies and betrayal, I've experienced it all in Russia.<br /><br />I know what I'm talking about. And here are my qualifications: Here are the photojournals of my three trips to Russia in search of a bride. It includes thousands of pics of many hot Russian girls I met, black comedy, scams I was privy to, and the story of my mugging and appearance on Russian national TV.<br /><br />http://www.happierabroad.com/Photojournals.htm<br /><br />It's like Reality TV. You will love it. I spent a ton of time putting it together. So check it out. The Russian woman that Nicole Kidman plays is a lot like the Julia and Katya in my photojournals.<br /><br />My 3 bride seeking trips in Russia happen to be very exciting and would sell, so why don't they make a movie out of my bride seeking adventures in Russia? However, there is one factual impossibility in this film, and that is the way which the guy orders his bride from a catalog and having her arrive at an airport. It doesn't work that way at all, so I don't understand why the media likes to perpetuate this. There isn't a single Russian bride introduction website that works this way, and I challenge anyone to find one that does. The fact is, you can only order the Russian lady's CONTACT INFO (email, address, phone number, etc.) from the website. From there, you correspond and then visit her, and if you want to bring her to your country, you start the immigration process at your INS office, and wait months after that. That's how it works in real life. You can't just order her to arrive at your airport. US Immigration would NEVER allow such a thing to happen.<br /><br />WuMaster <br /><br />- I got everything I wanted by going abroad! You can too! http://www.happierabroad.com
Given vector representations for individual words, it is necessary to compute vector representations of sentences for many applications in a compositional manner, often using artificial neural networks. Relatively little work has explored the internal structure and properties of such sentence vectors. In this paper, we explore the properties of sentence vectors in the context of automatic summarization. In particular, we show that cosine similarity between sentence vectors and document vectors is strongly correlated with sentence importance and that vector semantics can identify and correct gaps between the sentences chosen so far and the document. In addition, we identify specific dimensions which are linked to effective summaries. To our knowledge, this is the first time specific dimensions of sentence embeddings have been connected to sentence properties. We also compare the features of different methods of sentence embeddings. Many of these insights have applications in uses of sentence embeddings far beyond summarization.
We determine the time dependence of pressure and shear stress distributions on the surface of a pitching and deforming hydrofoil from measurements of the three dimensional flow field. Period-averaged stress maps are obtained both in the presence and absence of steady flow around the foil. The velocity vector field is determined via volumetric three-component particle tracking velocimetry and subsequently inserted into the Navier-Stokes equation to calculate the total hydrodynamic stress tensor. In addition, we also present a careful error analysis of such measurements, showing that local evaluations of stress distributions are possible. The flapping foil used in the experiments is designed to allow comparison with a small trapezoidal fish fin, in terms of the scaling laws that govern the oscillatory flow regime. Unsteady Euler-Bernoulli beam theory is employed to derive instantaneous transversal force distributions on the deflecting hydrofoil from its deflection and thereby validate the spatial distributions of hydrodynamic stresses obtained from the fluid velocity field. The consistency of the force time-dependence is verified using a control volume analysis.
I've known this young lady and her mom since she was a little girl playing with my sister. She has turned into a dynamic individual and a great community leader. She is indeed an inspiration to all, that with goals and hard work anyone in America can be successful. Way to go Jasmine
Not for me Tried these 5-6 times before work outs with and without meals and ending up feeling nauseous for 90% of the time I was at the gym. NOT WORTH IT! I'd rather do my workout a little tired than feeling like I'm going to throw up the entire time. Overall this product was not for me.
This work presents a detailed analysis of the combinatorics of modular operads. These are operad-like structures that admit a contraction operation as well as an operadic multiplication. Their combinatorics are governed by graphs that admit cycles, and are known for their complexity. In 2011, Joyal and Kock introduced a powerful graphical formalism for modular operads. This paper extends that work. A monad for modular operads is constructed and a corresponding nerve theorem is proved, using Weber's abstract nerve theory, in the terms originally stated by Joyal and Kock. This is achieved using a distributive law that sheds new light on the combinatorics of modular operads.
Infrared-active phonons in LaMnO_{3+\delta} were studied by means of the reflection and transmission spectroscopy from 50 to 800 cm^{-1} at room temperature. Powder and ceramic samples of the phases of Pnma-2 (\delta=0.02), Pnma-1 (\delta=0.08), and R3c (\delta=0.15) were investigated. Besides, energies of the dipole-active phonons in Pnma-2, Pnma-1 phases were obtained by lattice-dynamics calculations. The transformations of IR-active phonons with the increase of \delta in the sequence of Pnma-2, Pnma-1, R3c are discussed.
Order 1 Size Up and Polyester Design and colors were great, but the fabric was very clingy and tight. I usually wear a medium, and it was too small. Also, the fabric is very polyester, and not light. It didn't feel great, and would not have felt comfortable wearing this in hot weather at a beach or pool.
We theoretically study the nonlinear dynamics of the instability of counter-superflow in two miscible Bose-Einstein condensates. The condensates become unstable when the relative velocity exceeds a critical value, which is called counter-superflow instability. We reveal that the counter-superflow instability can lead to quantum turbulence by numerically solving the coupled Gross-Pitaevskii equations. The modes amplified by the instability grow into solitons and decay into quantized vortices.Eventually, the vortices become tangled and quantum turbulence of two superfluids. We show that this process may occur in experiments by investigating the dynamics in a 2D trapped system.
We consider a class of interaction terms that describes correlated tunneling of composite fermions between effective Landau levels. Despite being generic and of similar strength to that of the usual density-density couplings, these terms are not included in the accepted theory of the edges of fractional quantum Hall systems. Here we show that they may lead to an instability of the edge towards a new reconstructed state with additional channels, and thereby demonstrate the incompleteness of the traditional edge theory.
Bandwidth hungry video content has become the dominant contributor to the data traffic world over. Cellular networks are constantly evolving to meet the growing traffic demands. Over the past few years, wireless multicast has been garnering a lot of attention as a means of efficient resource utilization. Multicast transmission lets spectral resources to be shared between users streaming the same content. Even though multicast transmission allows to serve multiple users on the same resources, in order to serve all these users successfully, the base station cannot transmit the content at a rate greater than that decodable by the user with the worst channel conditions. In this paper, we propose a way to overcome this bottleneck. Video streaming services can sustain a certain amount of packet loss without any significant degradation in the quality experienced by the users. We leverage this loss tolerant nature of video streaming applications to improve the performance of multicast video services in LTE and 5G. We convert the problem of resource allocation for loss tolerant multicasting into the problem of stabilizing a queueing system. We then propose two throughput optimal Maximum Weight (MW) policies that successfully stabilize the constructed queueing system. However, brute force implementation of MW policies is mostly NP-hard. To overcome this, we propose a maximum weight bipartite matching approach that results in a polynomial time implementation of the proposed policies. We also evaluate the performance of our policies via extensive simulations.
Do not BUY!! I ordered this product, excited for the case and it was delivered to the wrong address. The location was across the country from me and I am disappointed. I did in fact put that this item was to be delivered to my location but somehow the case was delivered some where out of the blue. Final result- DONT WASTE YOUR MONEY.
Wishing many good returns on this investment of her time and efforts. She is making a difference; but the only lasting difference will be training internally so these jobs can be filled by trained doctors and nurses from local people. While education is completely paid for indigenous people who choose to attend university, it is unfortunate that higher education seems not to be encouraged. Perhaps that perception is what needs to be changed.
...Plain to me he just didn`t pay enough attention to some chapters in his darned old history classes. There are enough monuments around the world Mr. Spicer, even if you missed school that day, to assure any educated person will not forget that a fellow named Hitler used poison gas to murder millions of men, women, and children..
We present Chandra X-ray Observatory ACIS-S3 X-ray imaging observations and VLT/FORS2 and Hubble Space Telescope optical observations of two low-density Galactic globular clusters; NGC 6366 and M55. We detect 16 X-ray sources with 0.5-6.0 keV luminosities above Lx=4E30 erg/s within the half-mass radius of M55, of which 8 or 9 are expected to be background sources, and 5 within the half-mass radius of NGC 6366, of which 4 are expected to be background sources. Optical counterparts are identified for several X-ray sources in both clusters and from these we conclude that 3 of the X-ray sources in M55 and 2 or 3 of the X-ray sources in NGC 6366 are probably related to the cluster. Combining these results with those for other clusters, we find the best fit for a predicted number of X-ray sources in a globular cluster Nc=1.2 Gamma+1.1 Mh, where Gamma is the collision number and Mh is (half of) the cluster mass, both normalized to the values for the globular cluster M4. Some sources tentatively classified as magnetically active binaries are more luminous in X-rays than the upper limit of Lx~0.001Lbol of such binaries in the solar neighbourhood. Comparison with XMM and ROSAT observations lead us to conclude that the brightest X-ray source in M55, a dwarf nova, becomes fainter in X-rays during the optical outburst, in accordance with other dwarf novae. The brightest X-ray source in NGC 6366 is a point source surrounded by a slightly offset extended source. The absence of galaxies and Halpha emission in our optical observations argues against a cluster of galaxies and against a planetary nebula, and we suggest that the source may be an old nova.
Anything but Super absorbency is what the product is sold as, yet is anything but super absorbing. For someone who is looking to find something that can super absorb for more than 4 hours this is not it. Stick with name brand. The packaging is hard to get into. The applicator and plunger are difficult compared to other brands. You have to grip the sides just to detach the two of you know what I mean. These probably last two hours. Got these last minute and am not stuck with them. Will only use them on lighter days. Not worth it unless one wants a mess and doesn’t stay on top of them. For those who suffer from blood issues don’t bother.
To approach a more reliable observational signature of a high-spin Kerr black hole, one should take into account the effects of its surroundings. To this end we study in this paper the influence of a surrounding plasma. We consider its refractive and dispersive effects on photon trajectories and ignore the gravitational effects of plasma particles as well as the absorption or scattering processes of photons. With two specific plasma models, we obtain analytical formulae for the black hole shadow and for the observational quantities of an orbiting "hot spot" seen by an observer located far away from the black hole. We find that the plasma has a frequency-dependent dispersive effect on the size and shape of the black hole shadow and on the image position and redshift of the hot spot. These results may be tested by the Event Horizon Telescope in the future.
Nice socks, but not for large legs The socks are nicely made and well priced, but they don't work for overweight people, or people with swollen feet/ankles. I originally bought them for myself, but they cut into my calves so deeply, I gave them to my mother, who loves them. Use your weight as a guide before buying.
Cheap Junk We use our fog machine twice a year. Once on Halloween and once at a Halloween party. I am familiar with fog machines and do clean them out before putting them back in storage in their "Halloween bins". This one failed after two years (4 uses total). I will not buy again and do not recommend. Junk.
The CMS Detector consists of a large volume silicon tracker immersed in a high four Tesla magnetic field, together with a high resolution/granularity electromagnetic calorimeter and a nearly full solid angle coverage hadronic calorimeter. Particle flow reconstruction provides a global pp-collision event description by exploiting the combined information across all CMS sub-detectors, optimizing the reconstruction and the identification of each particle (photons, electrons, muons, unstable neutral hadrons, charged hadrons and neutral hadrons) in an event. This summary introduces the CMS particle flow algorithm, discusses the challenges associated with the LHC environment, and presents some first example results in the context of hadronic decays of taus as well as missing transverse energy.
We consider a thermal quantum harmonic oscillator weakly coupled to a heat bath at a different temperature. We analytically study the quantum heat exchange statistics between the two systems using the quantum-optical master equation. We exactly compute the characteristic function of the heat distribution and show that it verifies the Jarzynski-W\'ojcik fluctuation theorem. We further evaluate the heat probability density in the limit of long thermalization times, both in the low and high temperature regimes, and investigate its time evolution by calculating its first two cumulants.
Now I know what not to buy... As a bathroom fan this thing is ok...certainly quiet enough seems to move enough air. As a light it is not good. It’s is bright enough but I had to modify it to fit LED bulbs. The main issue with this light fixture is the globe/cover what ever you call it. It’s way too heavy and the install is blind. You have to try to thread it into a hollow threaded rod. It can be done...but only a thousand better ways to do it. I need 7 more bathroom exhaust fans for an up grade job I’m doing. There will be no more of these.
We study the excitation of mutual inclination between planetary orbits by a novel secular-orbital resonance in multiplanet systems perturbed by binary companions which we call "ivection". The ivection resonance happens when the nodal precession rate of the planet matches a multiple of the orbital frequency of the binary, and its physical nature is similar to the previously-studied evection resonance. Capture into an ivection resonance requires encountering the resonance with slowly increasing nodal precession rate, and it can excite the mutual inclination of the planets without affecting their eccentricities. We discuss the possible outcomes of ivection resonance capture, and we use simulations to illustrate that it is a promising mechanism for producing the mutual inclination in systems where planets have significant mutual inclination but modest eccentricity, such as Kepler-108. We also find an apparent deficit of multiplanet systems which would have nodal precession period comparable to binary orbital period, suggesting that ivection resonance may inhibit the formation or destablize multiplanet systems with external binary companion.
Sturdy, great service but should include spare end caps They replaced a part that was broken right away. Very responsive. I took away 1 star because the end caps that the top attach to are plastic and easily broken and they really should include a few extras of those. Everything else is very sturdy and should hold up nicely for a while
The role of frequency is very important in electromagnetics since it may significantly change how a material interacts with an incident wave if the frequency spectrum varies. Here, we demonstrate a new kind of microwave window that has the unique property of controlling transmission and reflection based not only on the frequency of an incoming wave but also on the waveform or pulse width. This surface can preferentially pass or reject different kinds of signals, such as short pulses or continuous waves, even if they occur at the same frequency. Such a structure can be used, for example, to allow long communication signals to pass through, while rejecting short radar pulses in the same frequency band. It is related to the classic frequency selective surface, but adds the new dimension of waveform selectivity, which is only possible by introducing nonlinear electronics into the surface. Thus, our study is expected to provide new solutions to both fundamental and applied electromagnetic issues ranging from traditional antenna design and wireless communications to emerging areas such as cloaking, perfect lenses, and wavefront shaping.
We have used the Spitzer 22-um peakup array to observe thermal emission from the nucleus and trail of comet 103P/Hartley 2, the target of NASA's Deep Impact Extended mission. The comet was observed on UT 2008 August 12 and 13, while the comet was 5.5 AU from the Sun. We obtained two 200-frame sets of photometric imaging over a 2.7-hour period. To within the errors of the measurement, we find no detection of any temporal variation between the two images. The comet showed extended emission beyond a point source in the form of a faint trail directed along the comet's anti-velocity vector. After modeling and removing the trail emission, a NEATM model for the nuclear emission with beaming parameter of 0.95 +/- 0.20 indicates a small effective radius for the nucleus of 0.57 +/- 0.08 km and low geometric albedo 0.028 +/- 0.009 (1 sigma). With this nucleus size and a water production rate of 3 x 10^28 molecules s-1 at perihelion (A'Hearn et al. 1995) we estimate that ~100% of the surface area is actively emitting volatile material at perihelion. Reports of emission activity out to ~5 AU (Lowry et al. 2001, Snodgrass et al. 2008) support our finding of a highly active nuclear surface. Compared to Deep Impact's first target, comet 9P/Tempel 1, Hartley 2's nucleus is one-fifth as wide (and about one-hundredth the mass) while producing a similar amount of outgassing at perihelion with about 13 times the active surface fraction. Unlike Tempel 1, it should be highly susceptible to jet driven spin-up torques, and so could be rotating at a much higher frequency. Barring a catastrophic breakup or major fragmentation event, the comet should be able to survive up to another 100 apparitions (~700 yrs) at its current rate of mass loss.
It is nice to see Suraj Barjatya back at what he is best at.A story woven around a marriage.It feels nice to have a movie in which there is no single scene which you would avoid watching with your family. Though the story is simple and does not contain any new elements,you still like the movie,because of the presentation, performances,and actually the over all treatment. Hats Off to Suraj.. The movie is about the fact that engagement leads to love. The depiction of the changes in the way of thinking,behaving once you get engaged is excellent. Director has definitely given it much thought and actors have done it to perfection.Though the movie is slow,you don't mind it,because you kind of get so much involved with the story that you just wanna continue watching the joy of this newly engaged couple. As a typical RajShree stuff it has many sentimental scenes which are highly likely to make viewer burst into tears(specially ladies). But when you come out of the cinema hall you are very much satisfied and feel that the ticket was worth :-).
I am uncertain what to make of this misshapen 2007 dramedy. Attempting to be a new millennium cross-hybrid between On Golden Pond and The Prince of Tides, this film ends up being an erratic mess shifting so mercurially between comedy and melodrama that the emotional pitch always seems off. The main problem seems to be the irreconcilable difference between Garry Marshall's sentimental direction and Mark Andrus' dark, rather confusing screenplay. The story focuses on the unraveling relationship between mother Lilly and daughter Rachel, who have driven all the way from San Francisco to small-town Hull, Idaho where grandmother Georgia lives. The idea is for Lilly to leave Rachel for the summer under Georgia's taskmaster jurisdiction replete with her draconian rules since the young 17-year old has become an incorrigible hellion.<br /><br />The set-up is clear enough, but the characters are made to shift quickly and often inexplicably between sympathetic and shrill to fit the contrived contours of the storyline. It veers haphazardly through issues of alcoholism, child molestation and dysfunctional families until it settles into its pat resolution. The three actresses at the center redeem some of the dramatic convolutions but to varying degrees. Probably due to her off-screen reputation and her scratchy smoker's voice, Lindsay Lohan makes Rachel's promiscuity and manipulative tactics palpable, although she becomes less credible as her character reveals the psychological wounds that give a reason for her hedonistic behavior. Felicity Huffman is forced to play Lilly on two strident notes - as a petulant, resentful daughter to a mother who never got close to her and as an angry, alcoholic mother who starts to recognize her own accountability in her daughter's state of mind. She does what she can with the role on both fronts, but her efforts never add up to a flesh-and-blood human being.<br /><br />At close to seventy, Jane Fonda looks great, even as weather-beaten as she is here, and has the star presence to get away with the cartoon-like dimensions of the flinty Georgia. The problem I have with Fonda's casting is that the legendary actress deserves far more than a series of one-liners and maternal stares. Between this and 2005's execrable Monster-in-Law, it does make one wonder if her best work is behind her. It should come as no surprise that the actresses' male counterparts are completely overshadowed. Garrett Hedlund looks a little too surfer-dude as the naïve Harlan, a devout Mormon whose sudden love for Rachel could delay his two-year missionary stint. Cary Elwes plays on a familiar suspicious note as Lilly's husband, an unfortunate case where predictable casting appears to telegraph the movie's ending.<br /><br />There is also the omnipresent Dermot Mulroney in the morose triple-play role of the wounded widower, Lilly's former flame and Rachel's new boss as town veterinarian Dr. Simon Ward. Laurie Metcalf has a barely-there role as Simon's sister Paula, while Marshall regular Hector Elizondo and songsmith Paul Williams show up in cameos. Some of Andrus' dialogue is plain awful and the wavering seriocomic tone never settles on anything that feels right. There are several small extras with the 2007 DVD, none all too exciting. Marshall provides a commentary track that has plenty of his trademark laconic humor. There are several deleted scenes, including three variations on the ending, and a gag reel. A seven-minute making-of featurette is included, as well as the original theatrical trailer, a six-minute short spotlighting the three actresses and a five-minute tribute to Marshall.
We propose a novel algorithm for the solution of mean-payoff games that merges together two seemingly unrelated concepts introduced in the context of parity games, small progress measures and quasi dominions. We show that the integration of the two notions can be highly beneficial and significantly speeds up convergence to the problem solution. Experiments show that the resulting algorithm performs orders of magnitude better than the asymptotically-best solution algorithm currently known, without sacrificing on the worst-case complexity.
Solar p-mode frequencies vary with solar activity. It is important to take this into account when comparing the frequencies observed from epochs that span different regions of the solar cycle. We present details of how to correct observed p-mode frequencies for the effects of the solar cycle. We describe three types of correction. The first allows mode frequencies to be corrected to a nominal activity level, such as the canonical quiet-Sun level. The second accounts for the effect on the observed mode frequencies, powers, and damping rates of the continually varying solar cycle and is pertinent to frequencies obtained from very long data sets. The third corrects for Sun-as-a-star observations not seeing all components of the modes. Suitable combinations of the three correction procedures allow the frequencies obtained from different sets of data to be compared and enable activity-independent inversions of the solar interior. As an example of how to apply the corrections we describe those used to produce a set of definitive Sun-as-a-star frequencies.
The carrier spin coherence in a p-doped GaAs/(Al,Ga)As quantum well with a diluted hole gas has been studied by picosecond pump-probe Kerr rotation with an in-plane magnetic field. For resonant optical excitation of the positively charged exciton the spin precession shows two types of oscillations. Fast oscillating electron spin beats decay with the radiative lifetime of the charged exciton of 50 ps. Long lived spin coherence of the holes with dephasing times up to 650 ps. The spin dephasing time as well as the in-plane hole g factor show strong temperature dependence, underlining the importance of hole localization at cryogenic temperatures.
We show that several integrable (i.e., exactly solvable) scalar cosmologies considered by Fr\'e, Sagnotti and Sorin (Nuclear Physics \textbf{B 877}(3) (2013), 1028--1106) can be generalized to include cases where the spatial curvature is not zero and, besides a scalar field, matter or radiation are present with an equation of state $p^{(m)} = w\, \rho^{(m)}$; depending on the specific form of the self-interaction potential for the field, the constant $w$ can be arbitrary or must be fixed suitably.
We use Gaia DR2 data to show that the globular cluster NGC5634 is physically associated with an arm of the Sagittarius Stream, the huge system of tidal tails created by the ongoing disruption of the Sagittarius dwarf spheroidal galaxy (Sgr dSph). Two additional arms of the Stream are also detected along the same line of sight, at different distances. We show that the Sgr Stream stars surrounding NGC5634 are more metal-poor, on average, than those found in the more distant Stream arm lying behind the cluster and in the main body of Sgr~dSph, confirming that a significant metallicity (and, presumably, age) gradient is present along the Stream. This analysis demonstrates the potential of the Gaia DR2 catalogue to directly verify if a cluster is physically associated to the Stream or not, without the need to rely on models of the tidal disruption of this system.

The world saw a different side of Pope Francis on New Year’s Eve after the pontiff tore himself free from a woman who had grabbed his hand and pulled him toward her. A woman seeking the Pope’s blessing on New Year’s Eve instead ended up enraging the pontiff after grabbing his arm to get his attention. A video of the altercation shows Francis walking through Vatican City as he greeted pilgrims. After reaching out to touch a child, a nearby woman seized his hand, jerking the religious leader around – a yank that appeared to cause him pain. Pope Francis repeatedly SLAPS woman’s hand after she YANKS him toward herDETAILS: https://t.co/V6taO9Jc9vpic.twitter.com/Iw7KrEdyuz — RT (@RT_com) 1 января 2020 г. After slapping her hand several times, the Pope freed himself of her grip. The usually serene Francis scowled as he walked away. According to reports, the Pope later acknowledged that he had “lost patience” with the admiring pilgrim. Francis has a history of repelling unwanted contact. In March, he was criticized for refusing to allow members of the faithful to kiss his papal ring during a visit to an Italian shrine. Like this story? Share it with a friend!
Recurrent neural network (RNN) based joint intent classification and slot tagging models have achieved tremendous success in recent years for building spoken language understanding and dialog systems. However, these models suffer from poor performance for slots which often encounter large semantic variability in slot values after deployment (e.g. message texts, partial movie/artist names). While greedy delexicalization of slots in the input utterance via substring matching can partly improve performance, it often produces incorrect input. Moreover, such techniques cannot delexicalize slots with out-of-vocabulary slot values not seen at training. In this paper, we propose a novel iterative delexicalization algorithm, which can accurately delexicalize the input, even with out-of-vocabulary slot values. Based on model confidence of the current delexicalized input, our algorithm improves delexicalization in every iteration to converge to the best input having the highest confidence. We show on benchmark and in-house datasets that our algorithm can greatly improve parsing performance for RNN based models, especially for out-of-distribution slot values.
In one-dimensional quantum lattice models with open boundaries, we find and study localization at the lattice edge. We show that edge-localized eigenstates can be found in both bosonic and fermionic systems, specifically, in the Bose-Hubbard model with on-site interactions and in the spinless fermion model with nearest-neighbor interactions. We characterize the localization through spectral studies via numerical diagonalization and perturbation theory, through considerations of the eigenfunctions, and through the study of explicit time evolution. We concentrate on few-particle systems, showing how more complicated edge states appear as the number of particles is increased.
In this paper an application of the recently introduced pre-Lie Magnus expansion to Jackson's q-integral and q-exponentials is presented. Twisted dendriform algebras, which are the natural algebraic framework for Jackson's q-analogues, are introduced for that purpose. It is shown how the pre-Lie Magnus expansion is used to solve linear q-differential equations. We also briefly outline the theory of linear equations in twisted dendriform algebras.
Very cute and flattering skirt! This skirt is super cute and very flattering. I had bought 2 different styles at the same time. One I hated and was to short and seemed for kids but this skirt was very cute! The buttons on side are nice addition and the slit is flattering. I'm 5'1 and 115lbs and got the medium because I saw it runs small.
Let $\phi:G\to G$ be an automorphism of a group which is a free-product of finitely many groups each of which is freely indecomposable and two of the factors contain proper finite index characteristic subgroups. We show that $G$ has infinitely many $\phi$-twisted conjugacy classes. As an application, we show that if $G$ is the fundamental group of a three-manifold that is not irreducible, then $G$ has property $R_\infty$, that is, there are infinitely many $\phi$-twisted conjugacy classes in $G$ for every automorphism $\phi$ of $G$.
This is possibly the most perfect film I have ever seen - in acting, adaptation and direction. It is self-contained and of a kind, so there is no point in saying that it is better or worse than other great films, just that it can stand by itself as a perfect work of art.<br /><br />And it was fun watching confused horror fans getting up and walking out!
"A Texas community is beset with a rash of mysterious killings involving some of the students from the local college. The sheriff investigating the death discovers the startling identity of the killer responsible for the murders. A NASA experiment involving cosmic rays has mutated an ape and turned it into an unstoppable killing machine with a thirst for blood," according to the DVD sleeve's synopsis.<br /><br />Or, could the creature really be a mutated alligator returning from a space-bound "Noah's Ark"? <br /><br />A long opening, with laughably straight 1960s couple Ralph Baker Jr. (as Chris) and Dorothy Davis (as Judy), suggests "Night Fright" might be a joyously bad movie; but, don't get your hopes up. After some innocent cavorting, the attractive collegiates discover another couple has encountered a monster; naturally, the creature is hell-bent on terrorizing young romantics. Sheriff John Agar (as Clint Crawford) isn't trusted by the younger set; but, he really wants to help.<br /><br />Mr. Agar was a friend of my aunt; he spoke about very few movies, and this wasn't one of them.
In this paper we obtain new effective results on the Halpern iterations of nonexpansive mappings using methods from mathematical logic or, more specifically, proof-theoretic techniques. We give effective rates of asymptotic regularity for the Halpern iterations of nonexpansive self-mappings of nonempty convex sets in normed spaces. The paper presents another case study in the project of {\em proof mining}, which is concerned with the extraction of effective uniform bounds from (prima-facie) ineffective proofs.
We generalize Penrose's notion of conformal infinity of spacetime, to situations with anisotropic scaling. This is relevant not only for Lifshitz-type anisotropic gravity models, but also in standard general relativity and string theory, for spacetimes exhibiting a natural asymptotic anisotropy. Examples include the Lifshitz and Schrodinger spaces (proposed as AdS/CFT duals of nonrelativistic field theories), warped AdS_3, and the near-horizon extreme Kerr geometry. The anisotropic conformal boundary appears crucial for resolving puzzles of holographic renormalization in such spacetimes.
*Warning - no plot spoilers ahead, but movie spoilers nonetheless...* My significant other rented this for me thinking it would be a terrific romance with an all-star cast. Wow - very, very wrong. This movie is an overdone, overwrought, and overly sentimental excuse to theatrically release a student film 15 years after it was shot! The copyright date on the box said 2005, yet during the very first flashback sequence I was looking at the clothes and hairdos that were supposed to be the early 1960s, and noticed that the girls especially were wearing late 80s/early 90s dresses and hairdos. It looked as if it had been shot a good 15 or 20 years before the rest of the film! I tried to convenience myself that it was a flashback, and therefore supposed to look old, but it looked WWWWWWWAAAAAAAAAAAAYYYYYYYYYYY more 80s than 60s or even 21st century trying to be 60s... then an adult coworker of the lead character turns up, and he looks just like the boy featured in the flashback sequences (yet it's a different, much older character whose youth is featured in the flashbacks). I was completely confused until I saw in the special features the short film included - it was all the flashback sequences, shot in 1990 as a complete student film of the same title as this movie! It also features commentary that includes the little boy all grown up (and indeed acting the co-worker in the 2005 scenes). Thus, this movie is just a shell of story woven around an old, re-cut student film put together as an obvious excuse to get it up to theatrical running time. The shell story, shot in 2005, is mostly about a man who has lost his wife and finds healing and redemption at the dance class that he promises a dying man he will attend in his stead (something about a promise made by the dying man in the early 60's to his girl that they would meet on the "fifth day of the fifth month of the fifth year of the new millennium - an excuse to shoot the segments around the old film in 2005?) These new scenes and plot might have been OK except the awful, overly sentimental score that repeats ad nauseum over almost every single new scene and the clichéd action that permeates the new movie. Don't bother. There's a reason why you've never heard of this movie even though it has a well-known cast - it's terrible.
but this is pathetic, not at all what my other flashlights can ... OK, so I laughed when I got this and put batteries in it and turned it on. I think a candle is brighter. I wasn't expecting a high powered spotlight, but this is pathetic, not at all what my other flashlights can do.
Proton-proton interaction and photo-hadronic interaction in cosmic accelerators are the two main channels for the production of cosmic ultra-high energy photons and neutrinos (TeV-PeV). In this Letter, we use FWW approach to obtain the production of cosmic ultra-high energy photons and neutrinos from the collision between UHE proton with magnetic field which could be considered as the virtualphoton in the rest frame of UHE proton. We name this as $pB$ process. The threshold for the occurrence of the $pB$ process is that the combination of the Lorentz factor of proton and the strength of the magnetic field is about $\gamma_p B \simeq 5\times 10^{18}$Gauss. Beyond this threshold, the rate of energy loss of proton due to the $pB$ process is about three orders higher than that due to the synchrotron radiation of proton in the same magnetic field. The $pB$ process might potentially happen in the atmosphere of white dwarfs, neutron stars or even that of stellar massive black holes.
Sweetener on the go. Such a convenience! It is really nice to have my favorite sugar alternative packaged in little take along packets! I LOVE swerve, and it is so convenient to have these to throw in my purse for dining out, or to use at a friend’s house. While they are a bit pricey, I cannot stand Equal or the pink stuff in my iced tea. Swerve or nothing, so i am thrilled to have my sweetener on the go!
Color centers in diamond micro and nano structures are under investigation for a plethora of applications. However, obtaining high quality color centers in small structures is challenging, and little is known about how properties such as spin population lifetimes change during the transition from bulk to micro and nano structures. In this manuscript, we studied various ways to prepare diamond samples containing silicon vacancy centers and measured how population lifetimes of orbital states change in pillars as we varied their dimensions from approximately 1 $\mu$m to 120 nm. We also researched the influence of the properties of the diamond substrate and the implantation and annealing methods on the silicon vacancy inhomogeneous linewidth and orbital lifetime. Our measurements show that nominally identical diamond samples can display significantly distinct inhomogeneous broadening. We observed weak indications that restricted vibrational modes in small structures may extend population lifetimes. However, imperfections in the crystal lattice or surface damage caused by etching reduce population lifetimes, especially in the smallest structures.
In this article we present the design and implementation of the Logoscope, the first tool especially developed to detect new words of the French language, to document them and allow a public access through a web interface. This semi-automatic tool collects new words daily by browsing the online versions of French well known newspapers such as Le Monde, Le Figaro, L'Equipe, Lib\'eration, La Croix, Les \'Echos. In contrast to other existing tools essentially dedicated to dictionary development, the Logoscope attempts to give a more complete account of the context in which the new words occur. In addition to the commonly given morpho-syntactic information it also provides information about the textual and discursive contexts of the word creation; in particular, it automatically determines the (journalistic) topics of the text containing the new word. In this article we first give a general overview of the developed tool. We then describe the approach taken, we discuss the linguistic background which guided our design decisions and present the computational methods we used to implement it.
This is a sad movie about this woman who thought her ex who she loved so much was probably dead, but really his scientist dad had just put a spell on him to turn him into this really cute shark-guy. Kind of like in Beauty and the Beast. It could probably use a ballroom dance scene and maybe some singing candlesticks, but there are some pretty gross plants instead. They make this one girl really itchy, so she lets herself get eaten by the shark-guy instead of scratching through the whole movie. The scientist guy is a good dad who tries to reunite his fishy shark son with the woman he was engaged to, he even arranges for them to have private time for s-e-x, but the woman in this is a really shallow snob and thinks the shark-guy is an ugly, icky monster and wants nothing to do with him. She gave up on love! Just because he was a shark! I thought it was pretty sad how all she had to do was kiss him and he'd turn back to normal and they'd live happily ever after, but it's not that kind of movie.
Steering waves in elastic solids is more demanding than steering waves in electromagnetism or acoustics. As a result, designing material distributions which are the counterpart of optical invisibility cloaks in elasticity poses a major challenge. Waves of all polarizations should be guided around an obstacle to emerge on the downstream side as though no obstacle were there. Recently, we have introduced the direct-lattice-transformation approach. This simple and explicit construction procedure led to extremely good cloaking results in the static case. Here, we transfer this approach to the dynamic case, i.e., to elastic waves or phonons. We demonstrate broadband reduction of scattering, with best suppressions exceeding a factor of five when using cubic coordinate transformations instead of linear ones. To reliably and quantitatively test these cloaks efficiency, we use an effective-medium approach.
Rob in Calgary - do you know that tuition for non-Canadians is about double that of Canadians? That is the real reason that overseas students are given preferential treatment. The government funds post-secondary education based on the number of CANADIAN students enrolled. All post-secondary institutions make their "real" money by charging foreign students significantly more to pursue an education. It makes sense financially for post-secondary institutions to accept more foreign students. A quick fix? Maintain the foreign tuition at its current price and deduct the amount paid by all foreign students from the government funding.
Fractional Hamiltonian Monodromy is a generalization of the notion of Hamiltonian Monodromy, recently introduced by N. N. Nekhoroshev, D. A. Sadovskii and B. I. Zhilinskii for energy-momentum maps whose image has a particular type of non-isolated singularities. In this paper, we analyze the notion of Fractional Hamiltonian Monodromy in terms of the Gauss-Manin Monodromy of a Riemann surface constructed from the energy-momentum map and associated to a loop in complex space which bypasses the line of singularities. We also prove some propositions on Fractional Hamiltonian Monodromy for 1:-n and m:-n resonant systems.
I appear to be in the minority on this one, but I found One True Thing to be schmaltzy, contrived and generally unpleasant. Not that the acting was all that bad, but the characters seemed little more than archetypes (the bad father, oh, but wait, maybe he's not unredeemably bad; maybe there can be a resolution at the end . . .). Admittedly, the woman I was with loved the movie, so maybe you'll like it. But I didn't.
With this Liberal government we will soon be bankrupt, first surfer boy brings all these refugees over saying they will be funded by federal gov. but after a year they become the province and city responsibilities where the monies are coming from you guessed it ..Instead of paying for abortions oversees we have two other alternatives !. Mind our own business which the bleeding hearts never seem to be able to do. 2. Spike the water and make them unable to reproduce, it would be a much easier and cheaper solution. Oh, another one would be to ship the politicians and bleeding hearts oversees to explain the hardships and hazards of raising children and maybe also teach them safe sex.
Dermont, Charley, Walker and a few others seems to think our current fiscal situation can be resolved simply by new taxes and restructuring the PF. It might in the very short term but after that pension liabilities, Medicaid and employee health insurance increases will have us talking about a lot more than cutting hockey, let alone entire sports department. Toss in government induced inflation and suddenly a restructured PF is a drop in the bucket. Contrary to what these guys are saying, they're really hoping oil goes back to 80/bbl and gas goes to 8/bbtu in a short span of less than ten years. All I can say is a magician can easily persuade the mind into believing anything.
Data compression is an efficient technique to save data storage and transmission costs. However, traditional data compression methods always ignore the impact of user preferences on the statistical distributions of symbols transmitted over the links. Notice that the development of big data technologies and popularization of smart devices enable analyses on user preferences based on data collected from personal handsets. This paper presents a user preference aware lossless data compression method, termed edge source coding, to compress data at the network edge. An optimization problem is formulated to minimize the expected number of bits needed to represent a requested content item in edge source coding. For edge source coding under discrete user preferences, DCA (difference of convex functions programming algorithm) based and k-means++ based algorithms are proposed to give codebook designs. For edge source coding under continuous user preferences, a sampling method is applied to give codebook designs. In addition, edge source coding is extended to the two-user case and codebooks are elaborately designed to utilize multicasting opportunities. Both theoretical analysis and simulations demonstrate the optimal codebook design should take into account user preferences.
50th Anniversary Remaster of a Classic Album This music has been around for a long time, as most folks reading this review know, and it's super-engaging. The CD history is: original US release in 1987, remastered in 2009, then remastered again by Giles Martin in 2019. This is my least-favorite of The Beatles' albums that Giles has remastered. He did succeed in bringing the vocal harmonies more forward, which I love, and also the guitars especially when George, Sir Paul, and John are all playing. However, I don't think this a bug step-change improvement from the 2009 remaster. Giles' recent remasters of Sgt. Peppers and The White Album had more impact, IMO, especially Sgt. Peppers which is fantastic. BTW, I just bought the original album remaster, not the Deluxe version with all the out-takes and stuff.
In my life I have seen many great and awful movies. I am not an expert in professional reviews, but I have definitely something to say about this one. Firstly, these actors are the worst I have seen... Their acting is so unreal that you even want to throw away the DVD in the first 2 minutes. I think that these actors were not interested in the quality. <br /><br />Another awful thing is about these dialogs - they are so lame. You sometimes feel uncomfortable when you hear them. It seems that your 14 year old son could act better. I feel that this movie had a budget similar to the cost of my 14 year old European car...<br /><br />Please, if my message reaches you - save your time and money.
The coherent interaction with ultrashort light pulses is a powerful strategy for monitoring and controlling the dynamics of wave packets in all states of matter. As light presents an oscillation period of a few femtoseconds ($T=2.6$~fs in the near infrared spectral range), the fundamental light-matter interaction occurs on the sub-cycle timescale, i.e. in a few hundred attoseconds. In this work, we resolve the dynamics of autoionizing states on the femtosecond timescale and observe the sub-cycle evolution of a coherent electronic wave packet in a diatomic molecule, exploiting a tunable ultrashort extreme ultraviolet pulse and a synchronized infrared field. The experimental observations are based on measuring the variations of the extreme ultraviolet radiation transmitted through the molecular gas. The different mechanisms contributing to the wave packet dynamics are investigated through theoretical simulations and a simple three level model. The method is general and can be extended to the investigation of more complex systems.
At SwissFEL, a fully non-invasive characterization of the beam energy distribution can be performed by means of a Synchrotron-Radiation-Monitor (SRM) imaging in the visible the transverse profile of the electron beam in a magnetic chicane. Under conditions of off-crest acceleration in the SwissFEL injector, according to a first order Taylor series expansion, the distribution of the relative energy of the electron beam can be linearly expressed as a function of the distribution of the electron longitudinal coordinates via the coefficient of the rf induced beam energy chirp. It is hence possible to express the distribution of the electron longitudinal coordinates at the entrance of the magnetic chicane of SwissFEL as a function of the distribution of the dispersed electron trajectories in the horizontal plane of the magnetic chicane. Machine parameters and instrument data at SwissFEL can be beam-synchronously acquired. A shot-by-shot correlation between the analysis results of the SRM camera images and the linear coefficient of the beam energy chirp resulting from the rf parameters of the injector can be hence established. Finally, taking into account the compression factor of the magnetic chicane, the electron bunch length at the exit of the magnetic chicane can be expressed as a function of the horizontal size of the electron beam imaged by the SRM. Bunch-length measurements performed by means of the SRM in the first magnetic chicane of SwissFEL will be presented.
In this paper, linearly structured partial polynomial inverse eigenvalue problem is considered for the $n\times n$ matrix polynomial of arbitrary degree $k$. Given a set of $m$ eigenpairs ($1 \leqslant m \leqslant kn$), this problem concerns with computing the matrices $A_i\in{\mathbb{R}^{n\times n}}$ for $i=0,1,2, \ldots ,(k-1)$ of specified linear structure such that the matrix polynomial $P(\lambda)=\lambda^k I_n +\sum_{i=0}^{k-1} \lambda^{i} A_{i}$ has the given eigenpairs as its eigenvalues and eigenvectors. Many practical applications give rise to the linearly structured structured matrix polynomial. Therefore, construction of the linearly structured matrix polynomial is the most important aspect of the polynomial inverse eigenvalue problem(PIEP). In this paper, a necessary and sufficient condition for the existence of the solution of this problem is derived. Additionally, we characterize the class of all solutions to this problem by giving the explicit expressions of solutions. The results presented in this paper address some important open problems in the area of PIEP raised in De Teran, Dopico and Van Dooren [SIAM Journal on Matrix Analysis and Applications, $36(1)$ ($2015$), pp $302-328$]. An attractive feature of our solution approach is that it does not impose any restriction on the number of eigendata for computing the solution of PIEP. The proposed method is validated with various numerical examples on a spring mass problem.
The error pattern correcting code (EPCC) can be constructed to provide a syndrome decoding table targeting the dominant error events of an inter-symbol interference channel at the output of the Viterbi detector. For the size of the syndrome table to be manageable and the list of possible error events to be reasonable in size, the codeword length of EPCC needs to be short enough. However, the rate of such a short length code will be too low for hard drive applications. To accommodate the required large redundancy, it is possible to record only a highly compressed function of the parity bits of EPCC's tensor product with a symbol correcting code. In this paper, we show that the proposed tensor error-pattern correcting code (T-EPCC) is linear time encodable and also devise a low-complexity soft iterative decoding algorithm for EPCC's tensor product with q-ary LDPC (T-EPCC-qLDPC). Simulation results show that T-EPCC-qLDPC achieves almost similar performance to single-level qLDPC with a 1/2 KB sector at 50% reduction in decoding complexity. Moreover, 1 KB T-EPCC-qLDPC surpasses the performance of 1/2 KB single-level qLDPC at the same decoder complexity.
We study electron transport through a semiconductor quantum ring with one input and two output terminals for an elastic scatterer present within one of the arms of the ring. We demonstrate that the scatterer not only introduces asymmetry in the transport probability to the two output leads but also reduces the visibility of the Aharonov-Bohm conductance oscillations. This reduction occurs in spite of the phase coherence of the elastic scattering and is due to interruption of the electron circulation around the ring by the potential defect. The results are in a qualitative agreement with a recent experiment by Strambini et al. [Phys. Rev. B {\bf 79}, 195443 (2009)]. We also indicate that the magnetic symmetry of the sum of conductance of both the output leads as obtained in the experiment can be understood as resulting from the invariance of backscattering to the input lead with respect to the magnetic field orientation.
AO_SCPLOWBSTRACTC_SCPLOWArtificial reefs (ARs) have been used to support fishing activities. Sessile invertebrates are essential components of trophic networks within ARs, supporting fish productivity. However, colonization by sessile invertebrates is possible only after effective larval dispersal from source populations, usually in natural habitat. While most studies focused on short term colonization by pioneer species, we propose to test the relevance of geographic location, shape, age and depth of immersion on the ARs long term colonization by species found in natural stable communities in the Gulf of Lion. We recorded the presence of five sessile invertebrates species, with contrasting life history traits and regional distribution in the natural rocky habitat, on ARs with different shapes deployed during two immersion time periods (1985 and the 2000s) and in two depth ranges (<20m and >20m). At the local level ([~]5kms), neither shape, depth nor immersion duration differentiated ARs assemblages. At the regional scale (>30kms), colonization patterns differed between species, resulting in diverse assemblages. This study highlights the primacy of geographical positioning over shape, immersion duration and depth in ARs colonization, suggesting it should be accounted for in maritime spatial planning.
Motivated by study of the autoequivalence group of triangulated categories via isometric actions on metric spaces, we consider curvature properties (CAT(0), Gromov hyperbolic) of the space of Bridgeland stability conditions with the canonical metric defined by Bridgeland. We then prove that the metric is neither CAT(0) nor hyperbolic, and the quotient metric by the natural $\mathbb{C}$-action is not CAT(0) in case of the Kronecker quiver. Moreover, we also show the hyperbolicity of pseudo-Anosov functors defined by Dimitrov-Haiden-Katzarkov-Kontsevich, which yields the lower-bound of entropy by the translation length. Finally, pseudo-Anosov functors in case of curves have completely been classified.
Curves in Lagrange Grassmannians appear naturally in the intrinsic study of geometric structures on manifolds. By a smooth geometric structure on a manifold we mean any submanifold of its tangent bundle, transversal to the fibers. One can consider the time-optimal problem naturally associate with a geometric structure. The Pontryagin extremals of this optimal problem are integral curves of certain Hamiltonian system in the cotangent bundle. The dynamics of the fibers of the cotangent bundle w.r.t. this system along an extremal is described by certain curve in a Lagrange Grassmannian, called Jacobi curve of the extremal. Any symplectic invariant of the Jacobi curves produces the invariant of the original geometric structure. The basic characteristic of a curve in a Lagrange Grassmannian is its Young diagram. The number of boxes in its kth column is equal to the rank of the kth derivative of the curve (which is an appropriately defined linear mapping) at a generic point. We will describe the construction of the complete system of symplectic invariants for parameterized curves in a Lagrange Grassmannian with given Young diagram. It allows to develop in a unified way local differential geometry of very wide classes of geometric structures on manifolds, including both classical geometric structures such as Riemannian and Finslerian structures and less classical ones such as sub-Riemannian and sub-Finslerian structures, defined on nonholonomic distributions.
Neural responses are often highly heterogeneous non-linear functions of multiple task variables, a signature of a high-dimensional geometry of the neural representations. We studied the representational geometry in the somatosensory cortex of mice trained to report the curvature of objects using their whiskers. High-speed videos of the whisker movements revealed that the task can be solved by linearly integrating multiple whisker contacts over time. However, the neural activity in somatosensory cortex reflects a process of non-linear integration of spatio-temporal features of the sensory inputs. Although the responses at first appear disorganized, we could identify an interesting structure in the representational geometry: different whisker contacts are disentangled variables represented in approximately, but not fully, orthogonal subspaces of the neural activity space. The observed geometry allows linear readouts to perform a broad class of tasks of different complexities without compromising the ability to generalize to novel situations.
We present results obtained from near-infrared JHK spectroscopic observations of novae V2491 Cyg and V597 Pup in the early declining phases of their 2007 and 2008 outbursts respectively. In both objects, the spectra displayed emission lines of HI, OI, HeI and NI. In V597 Pup, the HeI lines were found to strengthen rapidly with time. Based on the observed spectral characteristics, both objects are classified as He/N novae. We have investigated the possibility of V2491 Cyg being a recurrent nova as has been suggested. By studying the temporal evolution of the line widths in V2491 Cyg it appears unlikely that the binary companion is a giant star with heavy wind as in recurrent novae of the RS Oph type. Significant deviations from that of recombination case B conditions are observed in the strengths of the HI lines. This indicates that the HI lines, in both novae, are optically thick during the span of our observations. The slope of the continuum spectra in both cases was found to have a \lambda^-(3-3.5) dependence which deviates from a Rayleigh-Jeans spectral distribution. Both novae were detected in the post-outburst super-soft X-ray phase; V2491 Cyg being very bright in X-rays has been the target of several observations. We discuss and correlate our infrared observations with the observed X-ray properties of these novae.
By the acting in this movie, it is sometimes hard NOT to imagine that the cast are who they portray themselves to be. Unbridled passion and acting at times make this a very enjoyable and engaging movie. Wouldn't even have known about it except for HBO late night. And the biggest reason I like UK films much better than American ones are that the actors aren't afraid to act out what is needed.
Recent experiments reported an unusual nematic behavior of heavily hole-doped pnictides $A$Fe$_{2}$As$_{2}$, with alkali $A$ = Rb, Cs. In contrast to the $B_{2g}$ nematic order of the parent $Ae$Fe$_{2}$As$_{2}$ compounds (with alkaline earth $Ae$ = Sr, Ba), characterized by unequal nearest-neighbor Fe-Fe bonds, in the hole-doped systems nematic order is observed in the $B_{1g}$ channel, characterized by unequal next-nearest-neighbor Fe-Fe (diagonal Fe-As-Fe) bonds. In this work, using density functional theory, we attribute this behavior to the evolution of the magnetic ground state along the series $Ae_{1-x}A_{x}$Fe$_{2}$As$_{2}$, from single stripes for small $x$ to double stripes for large $x$. Our simulations using the reduced Stoner theory show that fluctuations of Fe moments are essential for the stability of the double-stripe configuration. We propose that the change in the nature of the magnetic ground state is responsible for the change in the symmetry of the vestigial nematic order that it supports.
Very tight waistband *edit Leggings themselves are a good material and and fit is good; but the waistband has a thick elastic band that is very very tight. *update* Customer service contacted me after I wrote the initial review. I was very happy with the treatment I received and was sent replacement pair of leggings in the same size that fit perfect. The pockets are a great size and these are excellent for running!
Recently, the CDF and D0 collaborations measured indirect CP violation in Bs -> J/psi phi and found a hint of a signal. If taken at face value, this can be interpreted as a nonzero phase of Bs-Bsbar mixing (beta_s), in disagreement with the standard model, which predicts that beta_s ~= 0. In this paper, we argue that this analysis may be incomplete. In particular, there can be new physics (NP) in the bbar -> sbar c cbar decay. If so, the value of beta_s is different than for the case in which NP is assumed to be present only in the mixing. We have examined several models of NP and found that, indeed, there can be significant contributions to the decay. These effects are consistent with measurements in B -> J/psi K* and Bd -> J/psi Ks. Due to the NP in the decay, polarization-dependent indirect CP asymmetries and triple-product asymmetries are predicted in Bs -> J/psi phi.
The emergence of the Pomeranchuk instability (PI) in a Helical Fermi liquid (HFL) residing on the surface of a three-dimensional topological insulator (3D TI) is addressed at the mean-field level. An expression for the PI condition is derived in terms of a few microscopic parameters in each angular momentum channel corresponding to a central interaction between the helical electrons. It is found that because of the presence of strong spin-orbit coupling (SOC) the Landau parameter, $\bar{F}_{l}$ corresponding to a particular angular momentum channel $l$ depends not only on the electron-electron interaction in the same channel but also interactions in $(l+1)$ and $(l-1)$ channels. The formalism automatically excludes the $l=1$ PI in the HFL where the Galilean invariance is broken because of the presence of strong SOC. It is also found that the competing PIs can only be avoided until the appearance of $l=2$ PI. In this case, the corresponding nematic instability can even be achieved in the $l=1$ angular momentum channel of interaction between the electrons. The range of interaction between the electrons plays a pivotal role in bringing out the PIs. This is established by analysing a few realistic profiles of the interaction. Another class of instability, involving a change in the topology of the Fermi surface without breaking the rotational symmetry, is found which competes with the PIs. Quantum phase transition originating from this instability is quite similar to the Lifshitz transition but is driven by electron-electron interaction. Possible connections of this instability with experiments are also described briefly.
but i had a cousin of mine that was in a different nursing home which was sort of nicer you know and until really close to the end she was able to go out and take walks and things and they took her outside and in some ways i think it might have even
In this paper, we prove an isoperimetric inequality for lower order eigenvalues of the Dirichlet Laplacian on bounded domains of a Euclidean space which strengthens the well-known Ashbaugh-Beguria inequality conjectured by Payne-P\'olya-Weinberger on the ratio of the first two Dirichlet eigenvalues and makes an important step toward the proof of a conjecture by Ashbaugh-Benguria.
We propose a technique for achieving large improvements in carrier mobilities in 2- and 1-dimensional semiconductor nanostructures by modifying their dielectric environments. We show that by coating the nanostructures with high-$\kappa$ dielectrics, scattering from Coulombic impurities can be strongly damped. Though screening is also weakened, the damping of Coulombic scattering is much larger, and the resulting improvement in mobilities of carriers can be as much as an order of magnitude for thin 2D semiconductor membranes, and more for semiconductor nanowires.
The measure and conquer approach has proven to be a powerful tool to analyse exact algorithms for combinatorial problems, like Dominating Set and Independent Set. In this paper, we propose to use measure and conquer also as a tool in the design of algorithms. In an iterative process, we can obtain a series of branch and reduce algorithms. A mathematical analysis of an algorithm in the series with measure and conquer results in a quasiconvex programming problem. The solution by computer to this problem not only gives a bound on the running time, but also can give a new reduction rule, thus giving a new, possibly faster algorithm. This makes design by measure and conquer a form of computer aided algorithm design. When we apply the methodology to a Set Cover modelling of the Dominating Set problem, we obtain the currently fastest known exact algorithms for Dominating Set: an algorithm that uses $O(1.5134^n)$ time and polynomial space, and an algorithm that uses $O(1.5063^n)$ time.
"We are called to promote a culture of dialogue by every possible means and thus to rebuild the fabric of society." I agree. Pope Francis then goes on to talk about "the foreigner, the immigrant and people from different cultures as worthy of being listened to." And he is quite right. But there is also the laity and women and LGBTQI people. When will the Church build structures that enable the hierarchy to listen to those who are outside their own closed circle? When will they get the courage to establish lay councils and open themselves to really listening to the lived experiences of those who are right there in front of them Sometimes the stranger is not someone from far away, but someone sitting right in front of you, who's story is also worthy of being listened to. Your might learn a thing or two, bishops, if you listened to those right in your own community.
Long enough to use the phone in bed while charging! I can use my phone in bed while charging it!! The original Apple cable wasn't long enough so I had to lean over to the night stand to use my phone. This cable is PERFECT!! Long enough to use it anywhere is bed. I love it!!
We define a closure operation for rings of mixed characteristic and verify that the closure is a ring. We then show that this closure produces a ring with good properties with respect to its Fontaine ring and give an example to show that rings that are not closed in this sense do not satisfy these properties.
Please refrain from attempting to conflate your irrational beliefs with substantiated fact. I have the same natural right of self defense on the 16th Street Mall as I do within the walls of my own home. Now, I might not have a right to display my discontent with the government by standing in front of the State Capitol with the stock of an AR-15 pressed against my cheek and the barrel pointed at the governor's office window (as was written in the SCOTUS decision pertaining to bearing arms in any manner for any purpose not being protected actions under the Constitution) but that is quite a different matter than the Constitution not protecting my right to have that AR-15 in my car or at my place of business.
Proceeding like Newton with a discrete time approach of motion and a geometrical representation of velocity and acceleration, we obtain Kepler's laws without solving differential equations. The difficult part of Newton's work, when it calls for non trivial properties of ellipses, is avoided by the introduction of polar coordinates. Then a simple reconsideration of Newton's figure naturally leads to en explicit expression of the velocity and to the equation of the trajectory. This derivation, which can be fully apprehended by beginners at university (or even before) can be considered as a first application of mechanical concepts to a physical problem of great historical and pedagogical interest.
A great performance by Emily Grace! I stumbled upon this movie while browsing my satellite listings and was curious by the summary of the plot giving by my satellite service provider. I was high entertained and had much compassion for the character "Alice" played by Emily Grace. The story had me guessing in what would happen to Alice and was not predicable. The overall story was refreshing and had some great twists to the supporting characters. The ending of the story ended on a rather fair way. I will purchase this DVD to add to my library. I am a new fan of Emily Grace and I high anticipate in seeing more from her performances.
We have combined multi-wavelength observations of a selected sample of starforming galaxies with galaxy evolution models in order to compare the results obtained for different SFR tracers and to study the effect that the evolution of the starforming regions has on them. We also aimed at obtaining a better understanding of the corrections due to extinction and nuclear activity on the derivation of the SFR. We selected the sample from Chandra data for the well studied region Chandra Deep Field South (CDFS) and chose the objects that also have UV and IR data from GALEX and GOODS-Spitzer respectively. Our main finding is that there is good agreement between the extinction corrected SFR(UV) and the SFR(X), and we confirm the use of X-ray luminosities as a trustful tracer of recent star formation activity. Nevertheless, at SFR(UV) larger than about 5Msol/year there are several galaxies with an excess of SFR(X) suggesting the presence of an obscured AGN not detected in the optical spectra. We conclude that the IR luminosity is driven by recent star formation even in those galaxies where the SFR(X) is an order of magnitude higher than the SFR(UV) and therefore may harbour an AGN. One object shows SFR(X) much lower than expected based on the SFR(UV); this SFR(X) `deficit' may be due to an early transient phase before most of the massive X-ray binaries were formed. An X-ray deficit could be used to select extremely young bursts in an early phase just after the explosion of the first supernovae associated with massive stars and before the onset of massive X-ray binaries.
We present improved circuits intended for building a universal computer based on Random Pulse Computing (RPC) paradigm, a biologically-inspired way of computation in which variable is represented by a frequency of a Random Pulse Train (RPT) rather than a logic state. The RPC we mention here is also known as "stochastic unipolar computation" in newer literature. Unlike in previous art, where randomness is obtained from electronics noise or a pseudorandom shift register while processing circuitry is deterministic, in our approach both variable generation and signal processing rely on the random flip-flop (RFF) whose randomness is derived from a fundamentally random quantum process. This offers advantage in better precision and faster calculation.
In the present note, we show that, as a priori bounds, the vorticity dynamics derived from Leray's backward self-similarity hypothesis admits only trivial solution in viscous as well as inviscid flows. By analogy, there is no non-zero solution in the forward self-similar equation. Since the Navier-Stokes or Euler equations are invariant under space translation in the whole space, our analysis establishes that technically flawed arguments have been exploited in a number of past papers, notably in Necas, Ruzicka & Sverak (1996); Tsai (1998); and Pomeau (2016), where the presumed decays or bounds at infinity are ill-defined and non-existent. Furthermore, an effort has been made to exemplify an inappropriate application of the familiar extremum principles in the theory of linear elliptic equation.
We consider interaction effects in quantum point contacts on the first quantization plateau, taking into account all non momentum-conserving processes. We compute low-temperature linear and non-linear conductance, shot noise, and thermopower by perturbation theory, and show that they are consistent with experimental observations on the so-called "0.7 anomaly". The full temperature-dependent conductance is obtained from self-consistent second-order perturbation theory and approaches ~ e^2/h at higher temperatures, but still smaller than the Fermi temperature.
Broke before I could even use it once The first one I purchased broke after about a year so I went and order another one. The new one snapped in half while attached it to the hose. I barely tightened the thing at all and I'm not an olympic body builder or something. Very low quality.
Symmetry problems in harmonic analysis are formulated and solved. One of these problems is equivalent to the refined Schiffer's conjecture which was recently proved by the author. Let $k=const>0$ be fixed, $S^2$ be the unit sphere in $\mathbb{R}^3$, $D$ be a connected bounded domain with $C^2-$smooth boundary $S$, $j_0(r)$ be the spherical Bessel function. The harmonic analysis symmetry problems are stated in the following theorems: {\bf Theorem A.} {\em Assume that $\int_S e^{ik\beta \cdot s}ds=0$ for all $\beta\in S^2$. Then $S$ is a sphere of radius $a$, where $j_0(ka)=0$. } {\bf Theorem B.} {\em Assume that $\int_D e^{ik\beta \cdot x}dx=0$ for all $\beta\in S^2$. Then $D$ is a ball.
Picosecond carrier dynamics in indium antimonide (InSb) following excitation by below-bandgap broadband far infrared radiation were investigated at 200 K and 80 K. Using a novel THz-pump/THz-probe scheme with pump THz fields of 100 kV/cm and an intensity of 100 MW/cm^2, we observed carrier heating and impact ionization. The number of carriers produced exceeds 10^16 cm-3, corresponding to a change in carrier density Delta N/N of 700% at 80K. The onset of a well defined absorption peak at 1.2 THz is an indication of changes in LO and LA phonon populations due to cooling of the hot electrons.
As a serious attempt for constructing a new foundation for describing micro-incidents from a local causal standpoint, I explained before that each micro-entity can be assumed to be composed of a probability field joined to a particle (called a particle-field or PF system) which is endowed with energy, having an objective character. In this essay, some odd quantum phenomena including the tunneling effect, the measurement problem and the EPR theorem are reexamined in detail from the standpoint of the new theory.
The relation between force and stretch in the worm-like chain model of entropic elasticity is examined. Although no closed-form expression is valid for all values of forcing, solutions in the form of asymptotic series can be obtained under conditions of small and large applied force. The small and large stretch limits correspond to regular and boundary layer perturbation problems, respectively. The perturbation problems are solved and series solutions obtained for force as a function of stretch. The form of the asymptotic series suggest a uniform approximation valid for all stretch that is an improvement on existing approximations.
