This movie is really bad. Most of it looks like it was filmed either in a park or a basement. There's a giant spider but all we see of it is one leg. There are some worms that live in a cave that are just cheap sock puppets with cardboard teeth. And the plot is a bunch of post-apocalyptic mumbo jumbo that makes no sense at all. The whole thing is just laughable.
1- Stephen Baldwin doesn't care about his involvement in Stephen Baldwin vehicles.<br /><br />2- The acting in any Stephen Baldwin vehicle ranges from horrible to mildly passable.<br /><br />3- Writers don't write Stephen Baldwin vehicles, children do.<br /><br />4- Most of the Stephen Baldwin vehicles revolve around one genre- the Actionless Action genre. It basically consists of crappy action sequences made with little to no effort whatsoever. <br /><br />5- The director doesn't care about Stephen Baldwin vehicles; he passes his job to an orangutan from time to time.<br /><br />And now you know.
Quantum algorithms can deliver asymptotic speedups over their classical counterparts. However, there are few cases where a substantial quantum speedup has been worked out in detail for reasonably-sized problems, when compared with the best classical algorithms and taking into account realistic hardware parameters and overheads for fault-tolerance. All known examples of such speedups correspond to problems related to simulation of quantum systems and cryptography. Here we apply general-purpose quantum algorithms for solving constraint satisfaction problems to two families of prototypical NP-complete problems: boolean satisfiability and graph colouring. We consider two quantum approaches: Grover's algorithm and a quantum algorithm for accelerating backtracking algorithms. We compare the performance of optimised versions of these algorithms, when applied to random problem instances, against leading classical algorithms. Even when considering only problem instances that can be solved within one day, we find that there are potentially large quantum speedups available. In the most optimistic parameter regime we consider, this could be a factor of over $10^5$ relative to a classical desktop computer; in the least optimistic regime, the speedup is reduced to a factor of over $10^3$. However, the number of physical qubits used is extremely large, and improved fault-tolerance methods will likely be needed to make these results practical. In particular, the quantum advantage disappears if one includes the cost of the classical processing power required to perform decoding of the surface code using current techniques.
The paper is a continuation of our previous work on the spatially homogeneous Boltzmann equation for Bose-Einstein particles with quantum collision kernel that includes the hard sphere model. Solutions $F_t$ under consideration that conserve the mass, momentum, and energy and converge at least weakly to equilibrium $F_{{\rm be}}$ as $t\to\infty$ have been proven to exist at least for radially symmetric and non-singular initial data, and for the case of low temperature, $F_t$ have to be positive Borel measures. The new progress is as follows: we prove that the long time convergence of $F_t(\{0\})$ to the Bose-Einstein condensation $F_{{\rm be}}(\{0\})$ for low temperature holds for all radially symmetric and non-singular initial data $F_0$. This immediately implies the long time strong convergence to equilibrium. We also obtain an algebraic rate of the strong convergence for arbitrary temperature. Our proofs are based on the entropy control, Villani's inequality for the entropy dissipation, a suitable time-dependent convex combination between the solution and a fixed positive function (in order to overcome the lack of positive lower bound), the convex-positivity of the cubic collision integral, and an iteration technique for obtaining a positive lower bound of condensation.
We studied the magnetic properties, in particular dynamics, of the correlated spins associated with natural defects in the organic spin chain compounds ($o$-DMTTF)$_2X$ ($X$ = Br, Cl) by means of electron spin resonance (ESR) spectroscopy. Both materials exhibit spin-Peierls transitions at temperatures around 50 K [P. Foury-Leylekian et al. Phys. Rev. B 84, 195134 (2011)], which allow a separation of the properties of defects inside the chains from the magnetic response of the spin chains. Indeed, continuous wave ESR measurements performed over a wide temperature range evidence the evolution of the spin dynamics from being governed by the spins in the chains at elevated temperatures to a low-temperature regime which is dominated by defects within the spin-dimerized chains. Such defects polarize the antiferromagnetically coupled spins in their vicinity, thereby leading to a finite local alternating magnetization around the defect site which can be described in terms of a soliton, i.e. a spin 1/2 quasiparticle built of many correlated spins, pinned to the defect. In addition, contributions of triplon excitations of the spin-dimerized state to the ESR response below the transition temperature were observed which provides a spectroscopic estimate for the spin-gap of the studied systems. Moreover, details of spin dynamics deep in the spin-Peierls phase were investigated by pulse ESR experiments which revealed Rabi-oscillations as signatures of coherent spin dynamics. From a comparison of the characteristic damping times of the Rabi oscillations with measurements of the spin relaxation times by means of primary-echo decay and CPMG methods it becomes evident that inhomogeneities in local magnetic fields strongly contribute to the soliton decoherence.
In 1934 B. Berggren first discovered the surprising result that every Pythagorean triplet is the pre product of the triplet (3, 4, 5) presented as a column by a product of three matrices, that every triplet is obtained in this manner exactly once and in primitive form. In this paper we show a similar result for integer triangles with an angle of 60 degrees (also known as Eisensteinian triplets). We show that any such triangle is obtained by pre-multiplication (7,8,5) or (13,15,7) by a product of five matrices. The result might have applications in enumerating points with rational distance from the origin on the hexagonal lattice.
Fun but lacking I love the never touch books but this one is my least favorite. It has the word hate in it so I have to keep reading doesn't appreciate to make it still rhyme. The rhymes are off and incorrect (rhyming Bye and by) and doesn't flow as nicely as the other books. My daughter still likes to play with the silicone pages though.
Nice putter, great price! I found this while searching for a 2 ball style putter. I figured for the cost it was no big loss of I didn't like it. Well i like it very much. The grip is very comfortable. I did have to shorten the shaft to fit my height. I was able to remove and reinstall the grip without damaging it. It would be nice if it were available in a different color scheme. I'm not crazy about lime green but it is growing on me. I like the feel of the ball off the face of the putter. The alignment system works well. Some of the reviews talk about the finish not holding up. I'm not sure what surface people are using it to putt on but I putt on grass. I have hundreds of putts on mine and there is not one single blemish, scratch or chip on it. Putting tip: It's really hard to control your speed of you drag the putter on the ground on the putting stroke. I put the cover on it when it is in my bag. I guess some people are just hard on equipment. If your looking for a two ball style putter give it a shot.
We report the results of a numerical simulation of a lattice formulation of the two-dimensional N=(2,2) super Yang-Mills theory proposed by Suzuki and Taniguchi. We measure the 1-point functions and 2-point functions. The scenario is that only tuning of the scalar mass to a specific value gives a supersymmetric continuum limit. Our results are consistent with this scenario although conclusive results on the restoration of supersymmetry have not been obtained.
My first impression when I read the synopsis for the upcoming movie was that it was going to be very, very different from the book. The movie trailer said that the movie is supposed to take place when Vivian is 19 years old after her parents were killed in a fire in America. She meets Aiden, an aspiring graphic novelist. Working in a chocolate shop in the day, she must accept that she will never be normal, because every full moon, she becomes a loup-garou--a thought-to-be mythical creature that can be closely compared to a werewolf.<br /><br />Most of the little changes didn't sound too bad to me, even though I am a fan of the book with the shared titled by Annette Curtis Klause. I knew it would be different, but I wanted to see it to support the book, thinking that an age change, a setting change, and a few little occupation changes wouldn't impact the storyline as a whole enough to make me want to tear my eyes out of their sockets and leave myself bleeding on the movie theatre ground.<br /><br />The movie unnecessarily killed off many important characters, one being Esme, Vivan's mother, right off the bat in the fire that was supposed to have killed her father. I pushed that aside and ventured forth into the movie, weary and slightly annoyed. Running through Romania, the camera angles were decent, the scenery was beautiful, and the music was... interesting... but it left me with the impression of, "Why does Vivian look like that, and why is she wearing a hoodie?" Jumping to later parts of the movie, I must say that I am surprised that the screenplay writers seemed to support incest in a way and rather than sticking to the character relationship from the book between Vivian and Rafe, the leader of The Five now became her cousin through her (surprise!) Aunt Astrid, who, in the novel, was the bitter and hated rival of Vivan's mother, and, might I add, no way related to either of them.<br /><br />To top off character distortions, Gabriel had somehow become the leader of the pack and obsessed over Vivian being his mate so they could fulfill some nonexistent prophecy. Not only did his physical appearance take a complete 180 from the description in the book, he was, apparently, also the father of Rafe. Yes, that's right, it's a nice little incestuous knot of wolfies all bundled up tight.<br /><br />Little things that irked me were scenes like the forest hunts. There was a red-head that stood out from the rest of the crowd, the one who "kissed their enemy" before their prey was set free to run and be hunted. Why was she there? Why did she look like Astrid? I suppose my mind is not vast enough to understand why such a character had to exist in the movie without any explanation as to WHY she existed other than to kiss pretty victims.<br /><br />I loved how the Amoeba was completely cut out of the movie. I loved how legally entwined Aiden's past was, what between the supposedly dramatic scene where he was telling Vivian about how his father wanted him to learn self-defense, and then beat his father up "in self-defense" to make him seem like such a tragic character.<br /><br />Character 180s are a lot of fun when they are completely unnecessary. At the end of the movie, I felt as if some person skimmed over the novel, scribbled down half the list of character names, drew a few connections here and there, mentioned that Gabriel was a bit of a jerk, Vivian fell in love with Aiden, he fears her when he finds out she is a loup-garou of the legends, and "somebody" is "killed by a silver bullet" and there is some sort of happy ending because Vivian finally feels accepted by somebody who loves her for who she is.<br /><br />I gave this movie a 2/10 because the camera shots were relatively decent, and the casting could have been worse, but as far as directing goes, why do the loup-garous leap into the air in human form as if they want to fly (with their arched backs and penchant to leap from high places), shimmer briefly, and then fall onto the ground as wolves? The only aspects of this movie that even had me watch it through to the very-sordid, sorry ending were the wolves, the beautiful scenery, and the eye-candy boys.<br /><br />All-together, I must say that in order to enjoy this film at all, one must be ready for misconceptions, strange happenings that are not always explained, incestuous innuendos, and have either not liked the book, or have not read the book.
Very expensive problems are very common in practical system that one fitness evaluation costs several hours or even days. Surrogate assisted evolutionary algorithms (SAEAs) have been widely used to solve this crucial problem in the past decades. However, most studied SAEAs focus on solving problems with a budget of at least ten times of the dimension of problems which is unacceptable in many very expensive real-world problems. In this paper, we employ Voronoi diagram to boost the performance of SAEAs and propose a novel framework named Voronoi-based efficient surrogate assisted evolutionary algorithm (VESAEA) for very expensive problems, in which the optimization budget, in terms of fitness evaluations, is only 5 times of the problem's dimension. In the proposed framework, the Voronoi diagram divides the whole search space into several subspace and then the local search is operated in some potentially better subspace. Additionally, in order to trade off the exploration and exploitation, the framework involves a global search stage developed by combining leave-one-out cross-validation and radial basis function surrogate model. A performance selector is designed to switch the search dynamically and automatically between the global and local search stages. The empirical results on a variety of benchmark problems demonstrate that the proposed framework significantly outperforms several state-of-art algorithms with extremely limited fitness evaluations. Besides, the efficacy of Voronoi-diagram is furtherly analyzed, and the results show its potential to optimize very expensive problems.
If light hidden sector photons exist, they could be produced through kinetic mixing with solar photons in the eV energy range. We propose to search for this hypothetical hidden photon flux with the Super-Kamiokande and/or upgraded CAST detectors. The proposed experiments are sensitive to mixing strengths as small as 10^-9 for hidden photon masses in the sub eV region and, in the case of non-observation, would improve limits recently obtained from photon regeneration laser experiments in this mass region.
We show that when TiO$_2$ anatase (001) is exposed to hydrogen plasma that the pristine surface termination becomes unfavorable to another, slightly modified, surface. On this modified surface the topmost TiO$_2$ layer is intact but out of registry with the bottom layers. Nevertheless, the modified surface has significantly improved ability to split water under exposure to sunlight. We show by explicit calculation of the water splitting reaction that the energy barrier that exists on a pristine surface is not present on the modified surface. The valence band maximum of the surface is raised relative to the pristine surface, which is a favorable way of adjusting the band gap in TiO$_2$ to the solar spectrum.
Pedestrians in videos have a wide range of appearances such as body poses, occlusions, and complex backgrounds, and there exists the proposal shift problem in pedestrian detection that causes the loss of body parts such as head and legs. To address it, we propose part-level convolutional neural networks (CNN) for pedestrian detection using saliency and boundary box alignment in this paper. The proposed network consists of two sub-networks: detection and alignment. We use saliency in the detection sub-network to remove false positives such as lamp posts and trees. We adopt bounding box alignment on detection proposals in the alignment sub-network to address the proposal shift problem. First, we combine FCN and CAM to extract deep features for pedestrian detection. Then, we perform part-level CNN to recall the lost body parts. Experimental results on various datasets demonstrate that the proposed method remarkably improves accuracy in pedestrian detection and outperforms existing state-of-the-arts in terms of log average miss rate at false position per image (FPPI).
Too small for my dogs tag The product seems good. I gave it to my mom for her dog because I didn’t realize it was the smaller bone so I couldn’t use it, but it seemed like good quality. But bummed it didn’t specify small bone, or at least I didn’t notice.
Jim Henson's The Muppet Movie is a charming, funny and brilliant film that can be watched AND enjoyed by adults and kids. I feel this is my favorite childhood film because it combines great characters, great story, and great wit that it is irresistable. The plot involves Kermit the frog (puppeteered and voiced by Henson) in his odyssey across America to follow his dream in Hollywood. Along the way, he meets Fozzie Bear, The Great Gonzo (my favorite), Miss Piggy, Rolf, and DR. Teeth and the electric mayhem.<br /><br />This film has so many good things I can't even say them. But it is memorable and every time I think of a puppet or muppet, I will think of this film. Look for cameos from Mel Brooks, Dom DeLouise, Paul Williams, Madeline Kahn, Bob Hope, Richard Pryor, Steve martin, Edgar Bergen (and Charlie McCarthey), Elliot Gould, Carol Kane and the great Orson Welles. Excellent and spectacular, one of the best films of the 70's. A++
On your own for installation, to an extent There were no instructions, and the video included on the Amazon site doesn’t show this exact model of rack. The video shows a different style of side brace than the parts with the blue ends. There also are thin rubbery pieces that might be to cushion where the side supports attach to the frame, but the video doesn’t show them being used. The video is somewhat helpful, but you’ll still have to guess with parts of the install.
This stuff is awesome. I drink it every evening after dinner to ... This stuff is awesome. I drink it every evening after dinner to help with digestion and general stomach uneasiness if it occurs. I've noticed that it also works great for stomach aches. It's great for detoxing as well, as half of the ingredients have been recommended for light detoxing.
Horrible Seller and experience BEWARE DO NOT BUY!!! I bought this and after 3 months of messaging the seller and amazon dozens of times, it took forever to get a refund because they either never sent the fridge or it was delayed several weeks without notice. Who knows, I just know the seller would not contact me!!
In a weakly ionized plasma, the evolution of the magnetic field is described by a "generalized Ohm's law" that includes the Hall effect and the ambipolar diffusion terms. These terms introduce additional spatial and time scales which play a decisive role in the cascading and the dissipation mechanisms in magnetohydrodynamic turbulence. We determine the Kolmogorov dissipation scales for the viscous, the resistive and the ambipolar dissipation mechanisms. The plasma, depending on its properties and the energy injection rate, may preferentially select one of the these dissipation scales. thus determining the shortest spatial scale of the supposedly self-similar spectral distribution of the magnetic field. The results are illustrated taking the partially ionized part of the solar atmosphere as an example. Thus the shortest spatial scale of the supposedly self-similar spectral distribution of the solar magnetic field is determined by any of the four dissipation scales given by the viscosity, the Spizer resistivity (electron-ion collisions), the resistivity due to electron-neutral collisions and the ambipolar diffusivity. It is found that the ambipolar diffusion dominates for resonably large energy injection rate. The robustness of the magnetic helicity in the partially ionized solar atmosphere would facilitate the formation of self-organized vortical structures.
In a family of drums used in the Indian subcontinent, the circular drum head is made of material of non-uniform density. Remarkably, and in contrast to a circular membrane of uniform density, the low eigenmodes of the non-uniform membrane are harmonic. In this work we model the drum head by a non-uniform membrane whose density varies smoothly between two prescribed values. Using a Fourier-Chebyshev spectral collocation method we obtain the eigenmodes and eigenvalues of the drum head. For a suitable choice of parameters, which we find by optimising a cost function, the eigenspectra obtained from our model are in excellent agreement with experimental values. Our model and the numerical method should find application in numerical sound synthesis.
The last few years have seen gamma-ray astronomy maturing and advancing in the field of time-domain astronomy, utilizing source variability on timescales over many orders of magnitudes, from a decade down to a few minutes and shorter, depending on the source. This review focuses on some of the key science issues and conceptual developments concerning the timing characteristics of active galactic nuclei (AGN) at gamma-ray energies. It highlights the relevance of adequate statistical tools and illustrates that the developments in the gamma-ray domain bear the potential to fundamentally deepen our understanding of the nature of the emitting source and the link between accretion dynamics, black hole physics, and jet ejection.
We present VULCAN/2D multi-group flux-limited-diffusion radiation hydrodynamics simulations of binary neutron star (BNS) mergers, using the Shen equation of state, covering ~100 ms, and starting from azimuthal-averaged 2D slices obtained from 3D SPH simulations of Rosswog & Price for 1.4 Msun (baryonic) neutron stars with no initial spins, co-rotating spins, and counter-rotating spins. Snapshots are post-processed at 10 ms intervals with a multi-angle neutrino-transport solver. We find polar-enhanced neutrino luminosities, dominated by $\bar{\nu}_e$ and ``$\nu_\mu$'' neutrinos at peak, although $\nu_e$ emission may be stronger at late times. We obtain typical peak neutrino energies for $\nu_e$, $\bar{\nu}_e$, and ``$\nu_\mu$'' of ~12, ~16, and ~22 MeV. The super-massive neutron star (SMNS) formed from the merger has a cooling timescale of ~1 s. Charge-current neutrino reactions lead to the formation of a thermally-driven bipolar wind with <$\dot{M}$> ~10$^{-3}$ Msun/s, baryon-loading the polar regions, and preventing any production of a GRB prior to black-hole formation. The large budget of rotational free energy suggests magneto-rotational effects could produce a much greater polar mass loss. We estimate that ~10$^{-4}$ Msun of material with electron fraction in the range 0.1-0.2 become unbound during this SMNS phase as a result of neutrino heating. We present a new formalism to compute the $\nu_i\bar{\nu}_i$ annihilation rate based on moments of the neutrino specific intensity computed with our multi-angle solver. Cumulative annihilation rates, which decay as $t^{-1.8}$, decrease over our 100 ms window from a few 10$^{50}$ to ~10$^{49}$ erg/s, equivalent to a few 10$^{54}$ to ~10$^{53}$ $e^-e^+$ pairs per second.
For every $m\in\mathbb{N}$, we establish the equidistribution of the sequence of the averaged pull-backs of a Dirac measure at any given value in $\mathbb{C}\setminus\{0\}$ under the $m$-th order derivatives of the iterates of a polynomials $f\in \mathbb{C}[z]$ of degree $d>1$ towards the harmonic measure of the filled-in Julia set of $f$ with pole at $\infty$. We also establish non-archimedean and arithmetic counterparts using the potential theory on the Berkovich projective line and the adelic equidistribution theory over a number field $k$ for a sequence of effective divisors on $\mathbb{P}^1(\overline{k})$ having small diagonals and small heights. We show a similar result on the equidistribution of the analytic sets where the derivative of each iterate of a H\'enon-type polynomial automorphism of $\mathbb{C}^2$ has a given eigenvalue.
Smelly and weak These SMELL. It's a very odd smell. I've no idea why they smell so bad/weird, but I'm hoping it goes away, as I threw the box away due to the fact that we we're moving and I just threw all the cardboard away at once. Also they're not very strong. Dont store anything heavy in them, but they're ok for lighter items.
The main result of the paper is a definition of possible ways of the confirmation of the Riemann hypothesis based on the properties of the vector system of the second approximate equation of the Riemann Zeta function. The paper uses a feature of calculating the Riemann Zeta function in the critical strip, where its approximate value is determined by partial sums of the Dirichlet series, which it is given. These expressions are called the first and second approximate equation of the Riemann Zeta function. The representation of the terms of the Dirichlet series by vectors allows us when analyzing the polyline formed by these vectors: 1) explain the geometric meaning of the generalized summation of the Dirichlet series in the critical strip; 2) obtain formula for calculating the Riemann Zeta function; 3) obtain the functional equation of the Riemann Zeta function based on the geometric properties of vectors forming the polyline; 4) explain the geometric meaning of the second approximate equation of the Riemann Zeta function; 5) obtain the vector equation of non-trivial zeros of the Riemann Zeta function; 6) determine why the Riemann Zeta function has non-trivial zeros on the critical line; 7) understand why the Riemann Zeta function cannot have non-trivial zeros in the critical strip other than the critical line.
It is shown, within classical mechanics, that the field of an electromagnetic vortex is capable of capturing and guiding neutral molecules endowed with a permanent electric dipole moment (PEDM). Similarly as in the case of the magnetic field applied to elementary particles or atoms, this effect turns out to be very delicate because of the small values of PEDM observed in real molecules. They amount to $2\times10^{5}\, e{\mathrm{fm}}$ (electron charge $\times$ fermi) or less, which requires the use of very strong electric fields. It has also been observed that there exists a threshold in field strength above which the particles are ejected from the trap. Trajectories of guided particles are usually quite chaotic, which is a consequence of non-linearity of the equations of motion. With a very special and precise adjustment of parameters, a regular (i.e., circular, in the transverse plane) trajectory can be obtained. The presence of an additional constant electric field pointing along the direction of the wave propagation might help to achieve the necessary tuning and realize such trajectories.
This contribution deals with identification of fractional-order dynamical systems. System identification, which refers to estimation of process parameters, is a necessity in control theory. Real processes are usually of fractional order as opposed to the ideal integral order models. A simple and elegant scheme of estimating the parameters for such a fractional order process is proposed. This method employs fractional calculus theory to find equations relating the parameters that are to be estimated, and then estimates the process parameters after solving the simultaneous equations. The data used for the calculations are intentionally corrupted to simulate real-life conditions. Results show that the proposed scheme offers a very high degree of accuracy even for erroneous data.
Not bad for the optical zoom amount Honestly did not expect much because we all know how good the Iphone quality is as far as pictures go, but I thought adding this would just make it a little better like the length at which I can capture good pictures. I was really surprised to see that not only did it maintain the quality of the Iphone camera, but it also allowed me to zoom in quite a bit and capture some really nice pictures. If you are my friend you would know what a picture fanatic I am, and this product really brightened my day! Thank you guys.
Recently, important updates were made for the hadronic contribution to the theoretical prediction of g-2. The isospin-breaking-corrections, needed in the comparison of the two pion spectral functions from tau decays and e+e- annihilations, were improved using new experimental and theoretical input. The recently published BABAR data were included in the global average of e+e- spectral functions. These data, as well as the ones from tau decays, were combined using newly developed software, featuring improved data interpolation and averaging, more accurate error propagation and systematic validation. The discrepancy between the e+e- and the tau-based result is reduced from previously 2.4 to 1.5 sigma. The full Standard Model prediction of g-2, obtained using e+e- data, differs from the experimental value by 3.2 standard deviations.
In the present note, we address the question about behavior of $L_3$-norm of the velocity field as time $t$ approaches blow-up time $T$. It is known that the upper limit of the above norm must be equal to infinity. We show that, for blow-ups of type I, the lower limit of $L_3$-norm equals to infinity as well.
Starting from H. Fr\"ohlich's second-quantized Hamiltonian for a $d$-dimensional electron gas in interaction with lattice phonons describing the quantum vibrations of a metal, we present a rigorous mathematical derivation of the superconducting state, following the principles laid out originally in 1957 by J. Bardeen, L. Cooper and J. Schrieffer. As in the series of papers written on the subject in the 90es, of which the present paper is a continuation, the representation of ions as a uniform charge background allows for a $(1+d)$-dimensional fermionic quantum-field theoretic reformulation of the model at equilibrium. For simplicity, we restrict in this article to $d=2$ dimensions and zero temperature, and disregard effects due to electromagnetic interactions. Under these assumptions, we prove transition from a Fermi liquid state to a superconducting state made up of Cooper pairs of electrons at an energy level $\Gamma_{\phi}\sim \hbar\omega_D e^{-\pi/m\lambda}$ equal to the mass gap, expressed in terms of the Debye frequency $\omega_D$, electron mass $m$ and coupling constant $\lambda$. The dynamical $U(1)$-symmetry breaking produces at energies lower than the energy gap $\Gamma_{\phi}$ a Goldstone boson, a non-massive particle described by an effective $(2+1)$-dimensional non-linear sigma-model, whose parameters and correlations are computed. The proof relies on a mixture of general concepts and tools (multi-scale cluster expansions, Ward identities), adapted to this quantum many-body problem with its extended infra-red singularity located on the Fermi circle, and a specific $1/N$-expansion giving the leading diagrams at intermediate energies. Ladder diagrams are proved to provide the leading behavior in the infra-red limit, in agreement with mean-field theory predictions.
The customer service is great! Couldn't ask for more Originally I gave this one star because it did not recover my 6 volt batteries. The seller (without me asking) refunded the entire amount, including shipping. To be fair, these were 6 year old batteries and I was hoping that I didn't have to buy new ones. The customer service is great! Couldn't ask for more. Sorry it didn't work out. I would try it again with the company backing its product this way.
Wireless Network-on-Chip (WNoC) appears as a promising alternative to conventional interconnect fabrics for chip-scale communications. The study of the channel inside the chip is essential to minimize latency and power. However, this requires long and computationally-intensive simulations which take a lot of time. We propose and implement an analytical model of the EM propagation inside the package based on ray tracing. This model could compute the electric field intensity inside the chip reducing the computational time several orders of magnitude with an average mismatch of only 1.7 dB.
The deformation of a loaded bike tire has been analyzed with a model consisting of a toroid of thin inextensible walls mounted on a central rim. If the tire radius is much shorter than the rim radius, the deflection, d, of the tire can be calculated as a function of the applied load, F. The solution can be approximated to a power law dependennce F proportional to d^(3/2) for small loads. The theoretical predictions compare well with the experiments carried out on two bicycle tires.
Wealthy businessman Bill Compton (played by Dennis Patrick) accidentally kills his daughter's hippie boyfriend after an argument. Panic-stricken, he retreats to a bar, and meets Joe Curran (played by Peter Boyle): a loud-mouth, angry, bigot who is bitter over how his beloved country has become. Unintentionally, Bill allows Joe to find out that he just killed a hippie. And this is only the beginning. "Joe" is a classic film of an unlikely friendship. A bond between two men, one of a white-collar background, the other of a blue-collar background. Bill & Joe have one thing in common, they are disgraced over how crazy the world has become. Dennis Patrick & Peter Boyle have both given very realistic portrayals of their characters. Director John G. Avidsen with this "pre-Rocky" effort, directs this low-budget gem with the same finesse as a movie with a $100 million budget. The script is loaded with excellent character development and very snappy, realistic dialog. In spite of its strengths this film does have its weaknesses. The script falls asleep roughly 3/4 of the way through, but it wakes up just in time for the jarring climax. This film also features a very early and uninspiring performance by a 24-year old Susan Sarandon as Bill's daughter Melissa, along with her hippie boyfriend Frank, portrayed very blandly by Patrick Mc Dermott. One could only be thankful that he was killed off early in the film. In spite of its few flaws this is one of those forgotten films of the 70's that should not be. Even though "Joe" is very dated to today's standards, the chemistry between Dennis Patrick & Peter Boyle is completely relevant today, and it is the glue that holds the whole film together.
This show is totally worth watching. It has the best cast of talent I have seen in a very long time. The premise of the show is unique and fresh ( I guess the executives at ABC are not used too that, as it was not another reality show). However this show was believable with likable characters and marvelous story lines. I am probably not in the age group they expect to like the show, as I am in my forty's, but a lot of my friends also loved it (Late 30's - mid 40's) and are dying for quality shows with talented cast members. I do not think this show was given enough time to gain an audience. I believe that given more time this show would have done very well. Once again ABC is not giving a show with real potential a real chance. With so many shows given chance after chance and not nearly worth it! They need to give quality shows a real chance and the time to really click and gain an audience. I really loved the characters and looked forward to watching each episode. I have been watching the episodes on ABC videos and the show keeps getting better and better. Although I think they owe us one more episode (Number 13?). We want to watch what we can! Bombard ABC with emails and letters and see if its possible to save this show from extinction. It certainly worked for Jerico. Some things are just worth saving and this show is definitely one of them. SIGN THE ONLINE PETITION TO ABC AT: http://www.PetitionOnline.com/gh1215/petition.html
This is a nice quality hose that is compact This is a nice quality hose that is compact, yet expands quickly when water is turned on. I love the length of the hose because I can water plants in my front yard, side yard and all the way to my back yard. There are a number of different nozzle options so you can change the spray force when watering delicate plants or filling up watering can. The grip on the nozzle is easy to hold and the right size so that your hand doesn’t get tired when watering plants.I love this items very much.
I had a close encounter of the black bear kind once in a campground in Seward Alaska. I had nothing but a coffee cup. But I did remember my "bear class" so i jumped up and down and screamed and yelled and waved my coffee cup. The bear looked at me and wandered off. My wife got a photo from inside the RV. I have seen bears run and they are FAST. Unless you have the gun loose in your hand A fast moving bear coming from cover will be on you before you can pull in out. In Kruger in South Africa all work crews are guarded by a ranger with a .404 bolt action rifle. Very sad .
Greybox fuzzing is a lightweight testing approach that effectively detects bugs and security vulnerabilities. However, greybox fuzzers randomly mutate program inputs to exercise new paths; this makes it challenging to cover code that is guarded by complex checks. In this paper, we present a technique that extends greybox fuzzing with a method for learning new inputs based on already explored program executions. These inputs can be learned such that they guide exploration toward specific executions, for instance, ones that increase path coverage or reveal vulnerabilities. We have evaluated our technique and compared it to traditional greybox fuzzing on 26 real-world benchmarks. In comparison, our technique significantly increases path coverage (by up to 3X) and detects more bugs (up to 38% more), often orders-of-magnitude faster.
Using methods of computer algebra, especially Gr\"obner bases for submodules of free modules over polynomial rings, we solve a classification problem in theory of algebraic operads: we show that the only nontrivial (possibly inhomogeneous) distributive law between the operad of Lie algebras and the operad of commutative associative algebras is given by the Livernet-Loday formula deforming the Poisson operad into the associative operad.
How does one represent an action? How does one describe an action that we have never seen before? Such questions are addressed by the Zero Shot Learning paradigm, where a model is trained on only a subset of classes and is evaluated on its ability to correctly classify an example from a class it has never seen before. In this work, we present a body pose based zero shot action recognition network and demonstrate its performance on the NTU RGB-D dataset. Our model learns to jointly encapsulate visual similarities based on pose features of the action performer as well as similarities in the natural language descriptions of the unseen action class names. We demonstrate how this pose-language semantic space encodes knowledge which allows our model to correctly predict actions not seen during training.
Two replicas of spatially extended chaotic systems synchronize to a common spatio-temporal chaotic state when coupled above a critical strength. As a prototype of each single spatio-temporal chaotic system a lattice of maps interacting via power-law coupling is considered. The synchronization transition is studied as a non-equilibrium phase transition, and its critical properties are analyzed at varying the spatial interaction range as well as the nonlinearity of the dynamical units composing each system. In particular, continuous and discontinuous local maps are considered. In both cases the transitions are of the second order with critical indexes varying with the exponent characterizing the interaction range. For discontinuous maps it is numerically shown that the transition belongs to the {\it anomalous directed percolation} (ADP) family of universality classes, previously identified for L{\'e}vy-flight spreading of epidemic processes. For continuous maps, the critical exponents are different from those characterizing ADP, but apart from the nearest-neighbor case, the identification of the corresponding universality classes remains an open problem. Finally, to test the influence of deterministic correlations for the studied synchronization transitions, the chaotic dynamical evolutions are substituted by suitable stochastic models. In this framework and for the discontinuous case, it is possible to derive an effective Langevin description that corresponds to that proposed for ADP.
A little too long It seems about two links two long for the 10" bar. I had to set the tightening screw to the furthest setting, so once it stretches out some (which it will do quickly) it won't be able to stay tight. This is on a Remington Pole Saw. Quick ship. Got it on time.
Super uncomfortable Even after wearing these for a while they still hurt far too much wear for any extended period of time. Whatever the breaking in period of these is, it isn't worth it. One of the worst purchases I've ever made. I suppose it depends what you intend to use these for, but I personally can't stand these.
In this paper we investigate learning visual models for the steps of ordinary tasks using weak supervision via instructional narrations and an ordered list of steps instead of strong supervision via temporal annotations. At the heart of our approach is the observation that weakly supervised learning may be easier if a model shares components while learning different steps: `pour egg' should be trained jointly with other tasks involving `pour' and `egg'. We formalize this in a component model for recognizing steps and a weakly supervised learning framework that can learn this model under temporal constraints from narration and the list of steps. Past data does not permit systematic studying of sharing and so we also gather a new dataset, CrossTask, aimed at assessing cross-task sharing. Our experiments demonstrate that sharing across tasks improves performance, especially when done at the component level and that our component model can parse previously unseen tasks by virtue of its compositionality.
An antidictionary code is a lossless compression algorithm using an antidictionary which is a set of minimal words that do not occur as substrings in an input string. The code was proposed by Crochemore et al. in 2000, and its asymptotic optimality has been proved with respect to only a specific information source, called balanced binary source that is a binary Markov source in which a state transition occurs with probability 1/2 or 1. In this paper, we prove the optimality of both static and dynamic antidictionary codes with respect to a stationary ergodic Markov source on finite alphabet such that a state transition occurs with probability $p (0 < p \leq 1)$.
The look is nice. It assembled pretty easy The look is nice. It assembled pretty easy. Cushions are super hard. Although I like the look and this is exactly what I was looking for it is uncomfortable and don't like that the cushions are not water resistant. I would not recommend this if you are looking for comfort.
It is believed that no information can be stored in Hawking radiation, because correlations between quanta of different field modes vanish. However, such correlations have been defined only with reference to a single moment of time. In this article, we develop a method for the evaluation of {\em multi-time} correlations. We find that these correlations are highly non-trivial: for a scalar field in the Schwarzschild black hole, multi-time correlations have an explicit dependence on angular variables and on the scattering history of Hawking quanta. This result leads us to the conjecture that some pre-collapse information can be stored in multi-time correlations after backreaction effects have been incorporated in the physical description.
The radiative induction of the CPT and Lorentz violating Chern-Simons (CS) term is reassessed. The massless and massive models are studied. Special attention is given to the preservation of gauge symmetry at higher orders in the background vector $b_\mu$ when radiative corrections are considered. Both the study of the odd and even parity sectors of the complete vacuum polarization tensor at one-loop order and a non-perturbative analysis show that this symmetry must be preserved by the quantum corrections. As a complement we obtain that transversality of the polarization tensor does not fix the value of the coefficient of the induced CS term.
We modify the Glauber dynamics of the Curie-Weiss model with dissipation in Dai Pra, Fischer, Regoli[2013] by considering arbitrary transition rates and we analyze the phase-portrait as well as the dynamics of moderate fluctuations for macroscopic observables. We obtain path-space moderate deviation principles via a general analytic approach based on the convergence of non-linear generators and uniqueness of viscosity solutions for associated Hamilton-Jacobi equations. The moderate asymptotics depend crucially on the phase we are considering and, moreover, their behavior may be influenced by the choice of the rates.
In the perturbative approach, substructures in the lens can be reduced to their effect on the two perturbative fields $f_1$ and $\frac{d f_0}{d\theta}$. A simple generic model of elliptical lens with a substructure situated near the critical radius is investigated in details. Analytical expressions are derived for each perturbative field, and basic properties are analyzed. The power spectrum of the fields is well approximated by a power-law, resulting in significant tails at high frequencies. Another feature of the perturbation by a substructure is that the ratio of the power spectrum at order $n$ of the 2 fields $R_n$ is nearly 1. The ratio $R_n \simeq 1$ is specific to substructures, for instance an higher order distortion ($n>2$) but with auto-similar isophotes will result in $R_n \propto \frac{1}{n^2}$. Finally, the problem of reconstructing the perturbative field is investigated. Local field model are implemented and fitted to maximize image similarity in the source plane. The non-linear optimization is greatly facilitated, since in the perturbative approach the circular source solution is always known. Examples of images distortions in the subcritical regime due to substructures are presented, and analyzed for different source shapes. Provided enough images and signal is available, the substructure field can be identified confidently. These results suggests that the perturbative method is an efficient tool to estimate the contribution of substructures to the mass distribution of lenses.
Box had been previously opened and some items used. The screen protector is perfect, however the box had been opened and the alcohol pads had been used. Whoever is packing needs to look more closely at the box. Again screen protector was unused so we didn't return. Other than that great product.
Claudine was one of the very first movies that gave positive role models for both Black men and women. I appreciated this movie even more as I got older. This movie shows that men didn't always turn away from responsibility. An excellent movie I'd always recommend for anyone who appreciates a good inner city love story.
The true face of liberalism is starting to show. They know which groups are too busy to organize protests and use these same groups as an escape goat to divert attention away from their own ideology and incompetenance. Unions, left wing groupies and those that won't work can organize protests on a moments notice and are rarely picked by liberals...disgusting that the harder you work, the less free time you have, the more your attacked by this government.
O_LIPositive Darwinian selection is the driving force underpinning local adaptation, and leaves footprints of selective sweeps at the underlying major genes. Quantifying the timing of selection and revealing the genetic bases of local adaptation in plants species occurring in steep and varying environmental gradients is crucial to predict a species ability to respond to climate changes and explore new niches. C_LIO_LIWe use whole genome sequence data from six populations across three different habitats of the wild tomato species Solanum chilense, to 1) infer the past demographic history, and 2) search for genes under strong positive selection. We then correlate current and past climatic projections with the demographic history, allele frequencies in space and time, the age of selection events, and changes in habitat suitability. C_LIO_LIWe find evidence for several selective sweeps targeting regulatory networks involved in root hair development in low altitude, and response to photoperiod and vernalization in high altitude populations. These sweeps occur in a concerted fashion in a given regulatory gene network at particular periods of substantial climatic change. C_LIO_LIWe decipher the genetic bases and the timing of local adaptation during plant colonization of semi-arid habitats using a unique combination of genome scans for selection and modelling of past climatic data.

Excellent Product! Only one minor issue Very satisfied so far - Does the job perfectly well! Already tested under various weather conditions including Partly Cloudy... Have used on a highway under a bright Sun and everything was fine, drove into the tunnel - and everything was still great... Alleys with trees on the sides have always been a big issue for me.... Now they are not! Only one downside so far is that when you fold it after use, its legs are touching the lens - might create scratches as time passes - That's the ONLY reason why only 4 stars... This is something the developers of the product have to think in the future. Everything else is just great!
We use an effective Markovian description to study the long-time behaviour of a nonlinear second order Langevin equation with Gaussian noise. When dissipation is neglected, the energy of the system grows as with time a power-law with an anomalous scaling exponent that depends both on the confining potential and on the high frequency distribution of the noise. The asymptotic expression of the Probability Distribution Function in phase space is calculated analytically. The results are extended to the case where small dissipative effects are taken into account.
You weren't banned because you were challenging. You were banned because you were BORING and you kept regurgitating the same left-wing slop. Since you aren't a real Catholic, banning you wasn't that big a deal. By your own admissions, you don't follow the teachings of the Church. Sorry, but some of us believe in truth-in-advertising, Colch.
My aim in this talk is to make clear that there are two sides to galaxy formation: the properties of the galaxies themselves, and the properties of the material that is left over from the galaxy formation process. To date, galaxy formation studies have focused on correctly predicting the properties of galaxies, and I will review the tremendous level of success in this area. However, these models usually ignore the ``flip side'' of galaxy formation: the intergalactic medium and the intra-group/intra-cluster medium (ICM). Yet, Chandra and XMM have given us a good view of the ICM and their results present an equally important challenge for theoretical models. I will show that this challenge is far from easy to meet, but describe the Bower et al 2008 model of galaxy formation which successfully combines both sides of the observational constraints.
Nice description of the situation in the US, it explains different kinds of Islam, not just show terrorist and extremist. Islam can be other thing that killing, they show why some people become terrorist and how to be Muslim without being extremist. It is a great series that Muslims and no-Muslims should see. Now we hope that other series or films will be done to change the idea of all Muslims are terrorist and all Americans want to destroy Islam. It gave me the interest to discover what Islam is exactly and what the US and also European government do to help cohabitation between people of different religion.
A central issue in the physics of high temperature superconductors is to understand superconductivity within a single copper-oxide layer or bilayer, the fundamental structural unit in the cuprates, and how it is lost with underdoping. As mobile holes are removed from the CuO_2 planes, the transition temperature T_C and superfluid density n_S decrease in a surprisingly correlated fashion in crystals and thick films. We seek to elucidate the intrinsic physics of bilayers in the strongly underdoped regime, near the critical doping level where superconductivity disappears. We report measurements of n_S(T) in films of Y_{1-x}Ca_xBa_2Cu_3O_{7-\delta} as thin as two copper-oxide bilayers with T_C's as low as 3 K. In addition to seeing the two-dimensional (2D) Kosterlitz-Thouless-Berezinski transition at T_C, we observe a remarkable scaling of T_C with n_S(0) that demonstrates that the disappearance of superconductivity with underdoping is due to quantum fluctuations near a T = 0 2D quantum critical point.
We show in this paper that the Z(3) flavor symmetry, which can successfully produce the tri-bimaximal mixing and flavor pattern of neutrino sector, has a possible explanation in the framework of gauge symmetry by constructing a wavefunction of flavor state particles with the help of the Wilson loop. In this implementation of Z(3) flavor symmetry, we suggest that the flavor charge in weak interaction can be interpreted as a topological charge. Its possible implications and generalizations to the quark sector are also discussed.
Explicit generators are found for the group $G_2$ of automorphisms of the algebra $\mS_2$ of one-sided inverses of a polynomial algebra in two variables over a field of characteristic zero. Moreover, it is proved that $$ G_2\simeq S_2\ltimes \mT^2\ltimes \Z\ltimes ((K^\ltimes E_\infty (\mS_1))\boxtimes_{\GL_\infty (K)}(K^\ltimes E_\infty (\mS_1)))$$ where $S_2$ is the symmetric group, $\mT^2$ is the 2-dimensional torus, $E_\infty (\mS_1)$ is the subgroup of $\GL_\infty (\mS_1)$ generated by the elementary matrices. In the proof, we use and prove several results on the index of operators, and the final argument in the proof is the fact that ${\rm K}_1 (\mS_1) \simeq K^*$ proved in the paper. The algebras $\mS_1$ and $\mS_2$ are noncommutative, non-Noetherian, and not domains. The group of units of the algebra $\mS_2$ is found (it is huge).
In a class of the gauge-Higgs unification models the 4D neutral Higgs boson, which is a part of the extra-dimensional component of the gauge fields, becomes absolutely stable as a consequence of the gauge invariance and dynamically generated new parity, serving as a promising candidate for cold dark matter (CDM). We show that the observed relic abundance of cold dark matter is obtained in the SO(5) x U(1) model in the warped space with the Higgs mass around 70 GeV. The Higgs-nucleon scattering cross section is found to be close to the current CDMS II and XENON10 bounds in the direct detection of dark matter.
A subset $A$ of a given finite abelian group $G$ is called $(k,l)$-sum-free if the sum of $k$ (not necessarily distinct) elements of $A$ does not equal the sum of $l$ (not necessarily distinct) elements of $A$. We are interested in finding the maximum size $\lambda_{k,l}(G)$ of a $(k,l)$-sum-free subset in $G$. A $(2,1)$-sum-free set is simply called a sum-free set. The maximum size of a sum-free set in the cyclic group $\mathbb{Z}_n$ was found almost forty years ago by Diamanda and Yap; the general case for arbitrary finite abelian groups was recently settled by Green and Ruzsa. Here we find the value of $\lambda_{3,1}(\mathbb{Z}_n)$. More generally, a recent paper of Hamidoune and Plagne examines $(k,l)$-sum-free sets in $G$ when $k-l$ and the order of $G$ are relatively prime; we extend their results to see what happens without this assumption.
Given a connected graph $G$ whose vertices are perfectly reliable and whose edges each fail independently with probability $q\in[0,1],$ the \textit{(all-terminal) reliability} of $G$ is the probability that the resulting subgraph of operational edges contains a spanning tree (this probability is always a polynomial in $q$). The location of the roots of reliability polynomials has been well studied, with particular interest in finding those with the largest moduli. In this paper, we will discuss a related problem -- among all reliability polynomials of graphs on $n$ vertices, which has a root of smallest modulus? We prove that, provided $n \geq 3$, the roots of smallest moduli occur precisely for the cycle graph $C_n$, and the root is unique.

We investigate the behavior of massless scalar, electromagnetic, and linearized gravitational perturbations near null infinity in d \geq 4 dimensional Minkowski spacetime (of both even and odd dimension) under the assumption that these fields admit a suitable expansion in 1/r. We also investigate the behavior of asymptotically flat, nonlinear gravitational perturbations near null infinity in all dimensions d\geq 4. We then consider the memory effect in fully nonlinear general relativity. We show that in even dimensions, the memory effect first arises at Coulombic order--i.e., order 1/r^{d-3}--and can naturally be decomposed into `null memory' and `ordinary memory.' Null memory is associated with an energy flux to null infinity. We show that ordinary memory is associated with the metric failing to be stationary at one order faster fall-off than Coulombic in the past and/or future. In odd dimensions, we show that the total memory effect at Coulombic order and slower fall-off always vanishes. Null memory is always of `scalar type', but the ordinary memory can be of any (i.e., scalar, vector, or tensor) type. In 4-spacetime dimensions, we give an explicit example in linearized gravity which gives rise to a nontrivial vector (i.e., magnetic parity) ordinary memory effect at order 1/r. We show that scalar memory is described by a diffeomorphism; vector and tensor memory cannot be. In d=4 dimensions, we show that there is a close relationship between memory and the charge and flux expressions associated with supertranslations. We analyze the behavior of solutions that are stationary at Coulombic order and show how these suggest `antipodal matching' between future and past null infinity, which gives rise to conservation laws. The relationship between memory and infrared divergences of the `out' state in quantum gravity is analyzed, and the nature of the `soft theorems' is explained.
Not even close to what’s advertised I just opened this and returned it immediately. Should’ve trusted my instincts and the other reviews on this one. Don’t buy unless you want embarrassing garbage. The picture I’m sharing is the advertised piece on top with what was delivered on the bottom. As you can see, there’s white paint mixed in with the blues in the middle, there’s no balance at all of the blues (it’s light blue over dark blue), the shading on the bark is all wrong. It’s what you get for $100, I guess. Shame on me.
A fundamental problem in distributed computing is the task of cooperatively executing a given set of $t$ tasks by $p$ processors where the communication medium is dynamic and subject to failures. The dynamics of the communication medium lead to groups of processors being disconnected and possibly reconnected during the entire course of the computation furthermore tasks can have dependencies among them. In this paper, we present a randomized algorithm whose competitive ratio is dependent on the dynamics of the communication medium and also on the nature of the dependencies among the tasks.
We propose to revisit the diffusion of atoms in the Knudsen regime in terms of a complex dynamical reflection process. By means of molecular dynamics simulation we emphasize the asymptotic nature of the cosine law of reflection at the atomic scale, and carefully analyze the resulting strong correlations in the reflection events. A dynamical interpretation of the accomodation coefficient associated to the slip at the wall interface is also proposed. Finally, we show that the first two moments of the stochastic process of reflection non uniformly depend on the incident angle.
Human language is a rich multimodal signal consisting of spoken words, facial expressions, body gestures, and vocal intonations. Learning representations for these spoken utterances is a complex research problem due to the presence of multiple heterogeneous sources of information. Recent advances in multimodal learning have followed the general trend of building more complex models that utilize various attention, memory and recurrent components. In this paper, we propose two simple but strong baselines to learn embeddings of multimodal utterances. The first baseline assumes a conditional factorization of the utterance into unimodal factors. Each unimodal factor is modeled using the simple form of a likelihood function obtained via a linear transformation of the embedding. We show that the optimal embedding can be derived in closed form by taking a weighted average of the unimodal features. In order to capture richer representations, our second baseline extends the first by factorizing into unimodal, bimodal, and trimodal factors, while retaining simplicity and efficiency during learning and inference. From a set of experiments across two tasks, we show strong performance on both supervised and semi-supervised multimodal prediction, as well as significant (10 times) speedups over neural models during inference. Overall, we believe that our strong baseline models offer new benchmarking options for future research in multimodal learning.
In Baker and Lorscheid's paper, they introduce a new hyperstructure: the polynomial hyperstructure Poly$(\mathbb{F})$ over a hyperfield $\mathbb{F}$. In this work, the author focuses on associativity of hypermultiplications in those hyperstructures and gives elementary propositions. The author also shows examples of polynomial hyperstructures over hyperfields with non-associative hypermultiplications. Then, he proves that though the hypermultiplication in Poly$(\mathbb{T})$ is associative for linear polynomials, it is not associative in general. Moreover, he shows that if $1\boxplus_{\mathbb{F}}1$ is not a singleton for hyperfield $\mathbb{F}:=(\mathbb{F},\odot,\boxplus_{\mathbb{F}},1,0)$, the hypermultiplication in Poly$(\mathbb{F})$ is not associative.
Metro-Goldwyn-Mayer is a very lost player in the short cartoon market. This market is essentially dominated by the Looney Tunes and the Merry Melodies shorts, coming from Warner Bros. But MGM is also able of releasing hidden gems, like "To Spring", an astonishing story about the most beautiful season of the year.<br /><br />In the environment depicted here, spring isn't caused by natural cycles, but is fabricated. And by who? By little male elves who live below ground. Each spring, when the snow begins to melt, they start working. They begin by felling rainbow rock columns, then reducing them to rubble and using this rubble to turn it into color fluids, which will be moved up to the ground and bearing grass, flowers... In other words, spring! The first half of the cartoon depicts spring's fabrication, but the second part is a little bit different. Old Man Winter comes back and he tries to extend winter by destroying the elves' work. So from this point, we assist to a battle between the elves and Old Man Winter.<br /><br />The music heard here is deliciously wonderful. The melodic parts stick in the head like an ink spot on a paper sheet. The second part melodies are thrilling and they perfectly fit with the action. This is just fantastico, Giorgio! The animation sequences are also a delight. The colors are well mixed and every little detail is shown into a massive, epic environment. The concept itself is brilliant. The elves are attracting characters, so is Old Man Winter, who effectively portrays the cold and ruthless feelings of the white season.<br /><br />There's also a strong message included here. The battle seems lost for the elves at the end, until a single late arriving elf jump into the action and it leads to the elves' victory over winter. So the point is: only one single person can make the difference.<br /><br />In conclusion, "To Spring" is a remarkable lost classic from short cartoon era. What is even more remarkable is that this cartoon's director made his debut here. And who is "To Spring"'s director? It's a certain William Hanna...
We consider the perturbative computation of the N-point function of chiral densities of massive free fermions at finite temperature within the thermofield dynamics approach. The infinite series in the mass parameter for the N-point functions are computed in the fermionic formulation and compared with the corresponding perturbative series in the interaction parameter in the bosonized thermofield formulation. Thereby we establish in thermofield dynamics the formal equivalence of the massive free fermion theory with the sine-Gordon thermofield model for a particular value of the sine-Gordon parameter. We extend the thermofield bosonization to include the massive Thirring model.
Scooby Doo is undoubtedly one of the most simple, successful and beloved cartoon characters in the world. So, what happens when you've been everywhere and done everything with the formula? You switch it up right? Wrong. You stop production and let it rest for a decade or so and then run it again, keeping the core of its success intact. That is to say, stick with the formula for the most part but add your particular flavour to it. This to me is why "What's New Scooby Doo" worked, they want back to the classic Scooby Doo formula which had only successfully resurfaced a decade earlier in "A Pup Named Scooby Doo" but for the most part had not been tapped since the original "Scooby Doo Where Are You".<br /><br />The first sign (to me) of a weak offering is the inclusion of extraneous characters; there might be a few fond memories from past iterations but generally if you think "Scooby Doo" you aren't thinking of Film-Flam, Scrappy Doo or Scooby Dum. Even worse, the exclusion of the other core members of "Mystery Inc" generally indicate a group of production people who don't understand from a kids point of view how the show works. The basic premise has always been a group of people who are diametrically opposed getting together and through their own individual, stereotyped qualities manage to surmount the tasks given at hand.<br /><br />This next paragraph is just my theorizing so skip it if you want: I hope that I can explain why I think fiddling around with the basic elements of the show are detrimental with my interpretation of what the gang represents and how they contribute to the whole; Fred represents the Driver, I think in general it is the purpose of Fred to give the group direction, organization and sub-tasks. Fred isn't a happy-go-lucky teenager, he's your boss, your teacher, your dad, your authority figure. Fred moves without hesitation and is driven by tasks (problem always equals solution for Fred). In many ways Fred is the antithesis to Shaggy. Shaggy is your best friend, that guy who is just a little more afraid of things than you are, he enables you to be brave, to not be at the back of the pack. Shaggy represents emotion and is frequently showing emotional extremes from elation to fear. Velma represents rational thought, she applies logic but as we see time and again on the show she requires clues that for the most part are collected in pieces by the other members of the show. Left on her own would Velma solve a mystery? The group often finds itself in situations where truths aren't obvious and only through chance encounters do they achieve the necessary information to complete their task, chance is represented by Daphne. At one point (I think it is the first Scooby Doo series) she was known as "danger prone". Writers have used Daphne to link unrelated events together through accident. She frequently is the one who finds the secret door, collection of objects or some other detail that can help the gang link clues together. Finally Scooby himself represents us, the participant. He is always in the centre of events, capable of all the things the rest of the gang are capable of, yet handicapped because he is not human and much like us the television viewer is unable to truly participate. Scooby Doo works because all these personified elements of problem solving are immediately identifiable and entertaining.<br /><br />Maybe I'm over thinking things but, in my life I've seen a lot of Scooby Doo (being a 30 year old self-proclaimed nerd, it kind of rolls with the territory). To me there is a magic with the classic "Scooby Doo" formula that should never be messed with.<br /><br />As many have pointed out; Scooby Doo is not a great work of art nor is it completely trite, it falls into the category of programming that can be watched by young eyes with a hearty bowl of breakfast cereal. Messing about with the raw simplicity transforms it into something else, something lesser.
We propose a simple non-supersymmetric grand unified theory (GUT) based on the gauge group $SO(10) \times U(1)_\psi$. The model includes 3 generations of fermions in ${\bf 16}$ ($+1$), ${\bf 10}$ ($-2$) and ${\bf 1}$ ($+4$) representations. The ${\bf 16}$-plets contain Standard Model (SM) fermions plus right-handed neutrinos, and the ${\bf 10}$-plet and the singlet fermions are introduced to make the model anomaly-free. Gauge coupling unification at $M_{GUT} \simeq 5 \times 10^{15}-10^{16}$ GeV is achieved by including an intermediate Pati-Salam breaking at $M_{I} \simeq 10^{12}-10^{11}$ GeV, which is a natural scale for the seesaw mechanism. For $M_{I} \simeq 10^{12}-10^{11}$, proton decay will be tested by the Hyper-Kamiokande experiment. The extra fermions acquire their masses from $U(1)_\psi$ symmetry breaking, and a $U(1)_\psi$ Higgs field drives a successful inflection-point inflation with a low Hubble parameter during inflation, $H_{inf} \ll M_{I}$. Hence, cosmologically dangerous monopoles produced from $SO(10)$ and PS breakings are diluted away. The reheating temperature after inflation can be high enough for successful leptogenesis. With the Higgs field contents of our model, a ${\bf Z}_2$ symmetry remains unbroken after GUT symmetry breaking, and the lightest mass eigenstate among linear combinations of the ${\bf 10}$-plet and the singlet fermions serves as a Higgs-portal dark matter (DM). We identify the parameter regions to reproduce the observed DM relic density while satisfying the current constraint from the direct DM detection experiments. The present allowed region will be fully covered by the future direct detection experiments such as LUX-ZEPLIN DM experiment. In the presence of the extra fermions, the SM Higgs potential is stabilized up to $M_{I}$.
In this paper we extend the setting of the online prediction with expert advice to function-valued forecasts. At each step of the online game several experts predict a function, and the learner has to efficiently aggregate these functional forecasts into a single forecast. We adapt basic mixable (and exponentially concave) loss functions to compare functional predictions and prove that these adaptations are also mixable (exp-concave). We call this phenomena integral mixability (exp-concavity). As an application of our main result, we prove that various loss functions used for probabilistic forecasting are mixable (exp-concave). The considered losses include Sliced Continuous Ranking Probability Score, Energy-Based Distance, Optimal Transport Costs & Sliced Wasserstein-2 distance, Beta-2 & Kullback-Leibler divergences, Characteristic function and Maximum Mean Discrepancies.
The results of the election can be summed up in a partial sentence from above " ...in a failed effort to fix the budget deficit." They failed. They put party ahead of state, didn't listen to their constituents, and now they are out. We will finish cleaning house during the November elections.
DOG FENCE Easy to use. First one I bought, the receiver didn't beep. I asked for a return, before I could return the old one, the new one had come in-great customer service. So far, I have no issues with it. I have a Catahoula that I like to keep in my yard of 15 acres, works great. I would recommend this product.
Buyers beware do not purchase First of all the assemble process is a not even worth writing about. As we opened the box and placed all the parts on my wood floor. The first thing was one of the boards look like it was stripped. Then as we start to examine all the boards we found termites in the wood. What the hell I have wood floors all over my house. I can’t believe this. Do not purchase this item I will never buy from this company again.
Recently, it is observed [Md. Nurujjaman et al, Phy. Rev. E \textbf{80}, 015201 (R) (2009)] that in an excitable system, one can maintain noise induced coherency in the coherence resonance by blocking the destructive effect of the noise on the system at higher noise level. This phenomenon of constant coherence resonance (CCR) cannot be explained by the existing way of simulation of the model equations of an excitable system with added noise. In this paper, we have proposed a general model which explains the noise induced resonance phenomenon CCR as well as coherence resonance (CR) and stochastic resonance (SR). The simulation has been carried out considering the basic mechanism of noise induced resonance phenomena: noise only perturbs the system control parameter to excite coherent oscillations, taking proper precautions so that the destructive effect of noise does not affect the system. In this approach, the CR has been obtained from the interference between the system output and noise, and the SR has been obtained by adding noise and a subthreshold signal. This also explains the observation of the frequency shift of coherent oscillations in the CCR with noise level.
Rip-off for what you get? Maybe or maybe not. The shampoo is terrible. It does not lather and leaves hair feeling greasy and grimy, because it doesn't seem to actually wash the hair, but just put another layer of grime on. The shampoo is also supposed to help prevent hair loss, but I am still losing just as much hair every day as I always have. The conditioner is okay, but nothing special. I cannot believe I paid that much money for products that do not work. I will not be buying this brand again, it's terrible. UPDATE: One month later... I figured out if I use three pumps of shampoo (it is very thin and watery) I can get a decent lather. My hair does feel less grimy these days. Maybe I am getting used to the product. My hair does feel pretty soft and healthy. I guess I will keep giving these products a try.
We present a deep learning framework based on a generative adversarial network (GAN) to perform super-resolution in coherent imaging systems. We demonstrate that this framework can enhance the resolution of both pixel size-limited and diffraction-limited coherent imaging systems. We experimentally validated the capabilities of this deep learning-based coherent imaging approach by super-resolving complex images acquired using a lensfree on-chip holographic microscope, the resolution of which was pixel size-limited. Using the same GAN-based approach, we also improved the resolution of a lens-based holographic imaging system that was limited in resolution by the numerical aperture of its objective lens. This deep learning-based super-resolution framework can be broadly applied to enhance the space-bandwidth product of coherent imaging systems using image data and convolutional neural networks, and provides a rapid, non-iterative method for solving inverse image reconstruction or enhancement problems in optics.
Providing assurances for self-adaptive systems is challenging. A primary underlying problem is uncertainty that may stem from a variety of different sources, ranging from incomplete knowledge to sensor noise and uncertain behavior of humans in the loop. Providing assurances that the self-adaptive system complies with its requirements calls for an enduring process spanning the whole lifetime of the system. In this process, humans and the system jointly derive and integrate new evidence and arguments, which we coined perpetual assurances for self-adaptive systems. In this paper, we provide a background framework and the foundation for perpetual assurances for self-adaptive systems. We elaborate on the concrete challenges of offering perpetual assurances, requirements for solutions, realization techniques and mechanisms to make solutions suitable. We also present benchmark criteria to compare solutions. We then present a concrete exemplar that researchers can use to assess and compare approaches for perpetual assurances for self-adaptation.
We consider the problem of designing control laws for stochastic jump linear systems where the disturbances are drawn randomly from a finite sample space according to an unknown distribution, which is estimated from a finite sample of i.i.d. observations. We adopt a distributionally robust approach to compute a mean-square stabilizing feedback gain with a given probability. The larger the sample size, the less conservative the controller, yet our methodology gives stability guarantees with high probability, for any number of samples. Using tools from statistical learning theory, we estimate confidence regions for the unknown probability distributions (ambiguity sets) which have the shape of total variation balls centered around the empirical distribution. We use these confidence regions in the design of appropriate distributionally robust controllers and show that the associated stability conditions can be cast as a tractable linear matrix inequality (LMI) by using conjugate duality. The resulting design procedure scales gracefully with the size of the probability space and the system dimensions. Through a numerical example, we illustrate the superior sample complexity of the proposed methodology over the stochastic approach.
I love Sarah Plain and Tall:Winters End. Its such a good movie. It tells of the hardships of living on a farm.I live on a farm so I know what its like to have hardships.<br /><br />I love the setting in Kansas. Its such a beautiful place. My favorite country star is from Kansas. I love the country in Kansas its just so beautiful. I would love to live in Kansas.<br /><br />Sarah Plain and Tall:Winters End I think is a love story. I love love stories they are so fun to watch. I like to watch them because it is nice to watch people fall in love. Falling in love is not as hard as most people think. I've fallen in love once. Sarah Plain and Tall: Winters End is my favorite love story
We identify and explore differential access to population-level signaling (also known as information design) as a source of unequal access to opportunity. A population-level signaler has potentially noisy observations of a binary type for each member of a population and, based on this, produces a signal about each member. A decision-maker infers types from signals and accepts those individuals whose type is high in expectation. We assume the signaler of the disadvantaged population reveals her observations to the decision-maker, whereas the signaler of the advantaged population forms signals strategically. We study the expected utility of the populations as measured by the fraction of accepted members, as well as the false positive rates (FPR) and false negative rates (FNR). We first show the intuitive results that for a fixed environment, the advantaged population has higher expected utility, higher FPR, and lower FNR, than the disadvantaged one (despite having identical population quality), and that more accurate observations improve the expected utility of the advantaged population while harming that of the disadvantaged one. We next explore the introduction of a publicly-observable signal, such as a test score, as a potential intervention. Our main finding is that this natural intervention, intended to reduce the inequality between the populations' utilities, may actually exacerbate it in settings where observations and test scores are noisy.
I recently watched this film on The Sundance Channel and it kept me interested from the start. However, it seems to take forever getting itself where it wants to go and in the end, I felt somewhat cheated. In a nutshell, Noble Willingham (of Walker, Texas Ranger fame) plays a boat salesman who starts getting harassed by telephone from a man claiming to be his son. According to the mysterious caller, Willingham has a dark, dirty little secret that affects the son and he (the son) is enjoying reminding him of it. I won't spoil anything for anyone but for me three things kept me from liking this movie a great deal. One, the movie has more foul language than Goodfellas, Scarface, Casino, and Glengarry Glen Ross combined. 99% of it is spewed from Willingham himself. It didn't take long to wear me out with constant four-letter words. Two, I simply could not believe that anyone would answer the telephone that many times, especially when one knows that a crank caller is on the other end of the line. No matter where Willingham is in the movie whether it be at work, home, a diner, etc., the phone rings and he always answers it spewing venom at the "son", and then hanging up ONLY TO ANSWER IT AGAIN WHEN THE CALLER CALLS BACK IN ABOUT TEN SECONDS! How many of us would do that? Now I realize that we probably do not have a movie if he doesn't keep answering, but I just could not suspend disbelief on that particular matter. Three, and this is the most minor of the criticisms, why is the director so opposed to showing us the "Corndog Man" (a.k.a. the caller/son)? Most of the time he's just a redneck sounding voice on the other end of the phone. I could have lived with that one if other things had fallen into place, but since they didn't it's just one more to tack on. I do give the movie credit for being a somewhat original idea and for holding my attention with suspense from the beginning but that's about it. Do see it, if only one time. However, if you're like me, you'll be saying "Triple K Marine!" in your sleep for a night or two after you finish watching it.
The aim of this paper is to determine the logical and computational strength of instances of the Bolzano-Weierstra{\ss} principle (BW) and a weak variant of it. We show that BW is instance-wise equivalent to the weak K\"onig's lemma for $\Sigma^0_1$-trees ($\Sigma^0_1$-WKL). This means that from every bounded sequence of reals one can compute an infinite $\Sigma^0_1$-0/1-tree, such that each infinite branch of it yields an accumulation point and vice versa. Especially, this shows that the degrees d >> 0' are exactly those containing an accumulation point for all bounded computable sequences. Let BW_weak be the principle stating that every bounded sequence of real numbers contains a Cauchy subsequence (a sequence converging but not necessarily fast). We show that BW_weak is instance-wise equivalent to the (strong) cohesive principle (StCOH) and - using this - obtain a classification of the computational and logical strength of BW_weak. Especially we show that BW_weak does not solve the halting problem and does not lead to more than primitive recursive growth. Therefore it is strictly weaker than BW. We also discuss possible uses of BW_weak.
The pp -> pp gamma reaction has been measured at a beam energy of 310 MeV by detecting both final protons in the PROMICE-WASA facility and identifying a missing-mass peak. For those events where the pp excitation is less than 3 MeV, the final diproton is almost purely in the 1S0 state and, under these conditions, there is complete coverage in the photon c.m. angle theta_gamma. The linear behaviour observed in cos^2(theta_gamma) shows that there is almost no influence of an E2 multipole at this energy, though the E1 and M2 must be rather similar in size.
Using the stochastic thermodynamics, we determine the entropy production and the dynamic heat capacity of systems subject to a sinusoidally time dependent temperature, in which case the systems are permanently out of thermodynamic equilibrium inducing a continuous generation of entropy. The systems evolve in time according to a Fokker-Planck or to a Fokker-Planck-Kramers equation. Solutions of these equations, for the case of harmonic forces, are found exactly from which the heat flux, the production of entropy and the dynamic heat capacity are obtained as functions of the frequency of the temperature modulation. These last two quantities are shown to be related to the real an imaginary parts of the complex heat capacity.
The complete fusion of $^9$Be with $^{144}$Sm and $^{208}$Pb targets is calculated in the coupled-channels approach. The calculations include couplings between the 3/2$^-$, 5/2$^-$, and 7/2$^-$ states in the $K=3/2$ ground state rotational band of $^9$Be. It is shown that the $B(E2)$ values for the excitation of these states are accurately described in the rotor model. The interaction of the strongly deformed $^9$Be nucleus with a spherical target is calculated using the double-folding technique and the effective M3Y interaction, which is supplemented with a repulsive term that is adjusted to optimize the fit to the data for the $^{144}$Sm target. The complete fusion is described by in-going-wave boundary conditions. The decay of the unbound excited states in $^9$Be is considered explicitly in the calculations by using complex excitation energies. The model gives an excellent account of the complete fusion (CF) data for $^9$Be+$^{144}$Sm, and the cross sections for the decay of the excited states are in surprisingly good agreement with the incomplete fusion (ICF) data. Similar calculations for $^9$Be+$^{208}$Pb explain the total fusion data at high energies but fail to explain the CF data, which are suppressed by 20%, and the calculated cross section for the decay of excited states is a factor of three smaller than the ICF data at high energies. Possible reasons for these discrepancies are discussed.
This movie basically is a very well made production and gives a good impression of a war situation and its effects on those involved. It's always interesting to see the story from the 'other' side for a change. This movie concentrates on a group of German soldiers who after fighting in the North Africa campaign are send to Stalingrad, Russia, where one of the most notorious and bloodiest battles of WW II is being fought.<br /><br />It's interesting to see the other side of this battle, since we mainly just always see the Germans simply as the 'villains'. In this movie those 'villains' are given an humane face and voice and it sort of makes you realize that the only true enemy in war is war itself and not necessarily those who you're fighting against. At first it's kind of hard to concentrate on the movie because you always just have in the back of your mind that the German's are the evil villains. But of course you get accustomed to it quickly and you soon adapt the Germans as the main characters of the movie and you even start to care -and be interested in them.<br /><br />The way this story is told isn't however the best. It's hard to keep track of the story at times, as it jumps from the one sequence and location to the other. The movie isn't always logic in its storytelling and features a bit too many sequences that remain too vague. It also is most of the time pretty hard to keep the characters apart and see who is who. It doesn't always makes this movie an easy on to watch but than again on the other hand, there are plenty enough sequences and moments present in this movie to make it worthwhile and an interesting one, just not the most coherent one around. In that regard Hollywood movies are always better than European movies.<br /><br />The production values are high and features some good looking sets and locations, though the movie wasn't even shot in Russia itself. It helps to create a good war time situation atmosphere.<br /><br />The character are mostly interesting although perhaps a tad bit formulaic. But I don't know, for some reason formulaic characters always work out fine in war movies and strenghtens the drama and realism. It also helps that they're being played by well cast actors. All of the actors aren't the best known actors around (Thomas Kretschmann was also at the time still a fairly unknown actor) but each of them fit their role well and gives its characters an unique face and personality.<br /><br />All in all not the best or most consistent WW II drama around but definitely worth a look, due to its original approach of the German side of the battle of Stalingrad and its good production values.<br /><br />7/10
First the seller and delivery were great. The bracelet itself was lovely First the seller and delivery were great. The bracelet itself was lovely. I was sensitive to the material in it. My wrist started to swell after a few hours. Pain went up my arm and the palm of my hand felt like it was burning. Weird, but I do have problems with being sensitive to odd things. I started to feel better after taking it off and within a couple of days all symptoms were gone. All of that being said...I gave the bracelet to my neighbor and she loves it. She has no problems at all.
In this publication we investigate dynamics of a flat FRW cosmological model with a non-minimally coupled scalar field with the coupling term $\xi R \psi^{2}$ in the scalar field action. The quadratic potential function $V(\psi)\propto \psi^{2}$ is assumed. All the evolutional paths are visualized and classified in the phase plane, at which the parameter of non-minimal coupling $\xi$ plays the role of a control parameter. The fragility of global dynamics with respect to changes of the coupling constant is studied in details. We find that the future big rip singularity appearing in the phantom scalar field cosmological models can be avoided due to non-minimal coupling constant effects. We have shown the existence of a finite scale factor singular point (future or past) where the Hubble function as well as its first cosmological time derivative diverges.
It wasn't very long ago that Tommie Smith and John Carlos were ostracized for doing a black power fist pump during the Olympic ceremonies. I guess it doesn't count when Trump brings this same insult to the national anthem up. Well he's Trump, so he must be wrong, but in this instance he is not. This is what he refers to, when he says "fake news". Pretending to be insulted by what he stated is fake/false/B.S.
A wide variety of tilted washboard potentials based on acoustic waves, electric fields, optical patterns and so on have been applied to sort particles in microchannels. In this paper, we present a theoretical analysis of the particles trajectory in a washboard potential making a tilt angle $\theta$ with the flow. Depending on the sorting to drag force ratio $\epsilon$, we identified a transition threshold $\epsilon = \cos(\theta)$ between two distinct regimes of particles motion: drift and locked modes. In drift mode, the particles follow an oscillating trajectory which slope is given by $\frac{\epsilon^2}{2}\tan(\theta)$, while in locked mode the trajectory slope is given by $1/\tan(\theta)$. These theoretical predictions agree quantitatively well with previously published experimental data and may help in the design of high-performance microfluidic sorting devices.
Jack Webb's movie 'The D.I' came about from the real life investigation into the deaths of several trainees in a swamp in Paris Isle in the 50's. As always, Webb, being the patriot that he is, came to the defense much like all the rest of his shows. I actually found this movie tame by 1957 standards. I served in the Army and can understand the intensity of the training at Parris Island (Camp Death by some)so this movie can never come close as does 'Full Metal Jacket'. I think this is a good movie which is more patriot than it is actual. But again, think of the time period it was made (1957) and what could be allowed and said on film at that time. I have always found Jack Webb to be clean cut and very loyal. I know many have criticized the film as one-sided and government propaganda. If you feel this way, watch 'Full Metal Jacket' with R Lee Ermey. I am a Webb fan and enjoy the movie for it's merit, not accuracy. As I have said, Webb believed in this country and held institutions to high moral standards (LAPD-Dragnet,Adam 12, Emergency etc). Just sit back and enjoy this one from a very strict moral time period in this country. Don't be too judgemental of Mr. Webb. Mark Lockwood Lubbock Texas..
