Too nice to put my dirty clothes in! This laundry basket is way too nice to put my dirty clothes in! I bought it with every intention of using it as a laundry basket, but it’s so so pretty, I opted to use it in my family room to put my throw blankets in. It was very easy to assemble and very nicely made. I couldn’t be happier with this purchase
In the catalytic addition of water to propyne the Au(III) catalyst is not stable under non-relativistic conditions and dissociates into a Au(I) compound and Cl2. This implies that one link in the chain of events in the catalytic cycle is broken and relativity may well be seen as the reason why Au(III) compounds are effective catalysts.
Electron transmission through chiral molecules induced by circularly polarized light can be very different for mirror-image structures, a peculiar fact given that the electronic energy spectra of the systems are identical. We propose that this asymmetry - as large as 10% for resonance transport- arises from different dynamical responses of the mirrored structures to coherent excitation. This behaviour is described in the context of a general novel phenomenon, current transfer, transfer of charge with its momentum information, that is outlined in terms of a simple tight binding model. This analysis makes it possible to account for the observed asymmetry in and off resonance, to characterize its dependence on the length of the molecular bridge and to examine effects of dephasing processes.
Love Sonicare I have been using Sonicare since I first saw them advertised many years ago; I got my whole family hooked on them and my recent order makes 3 of the cordless/battery powered units that I have bought. I would definitely recommend them My first battery powered unit is still as good as new and I have only changed batteries once since I purchased it about 5 years ago...great for those who travel a lot.
Hearing is a fundamental sense of many animals, including all mammals, birds, some reptiles, amphibians, fish, and arthropods. The auditory organs of these animals are extremely diverse in anatomy after hundreds of millions of years of evolution, yet all are made up of cellular tissues and are morphologically part of bodies of animals. Here we show hearing in the orb-weaving spider, Larinioides sclopetarius is not constrained by the organisms body but is extended through outsourcing hearing to its extended phenotype, the proteinaceous, self-manufactured orb-web. We find the wispy, wheel-shaped orb-web acts as a hyperacute acoustic "antenna" to capture the sound-induced air particle movements that approach the maximum physical efficiency, better than the acoustic responsivity of all previously known eardrums. By sensing the motion of web threads, the spider remotely detects and localizes the source of an incoming airborne acoustic wave such as those emitted by approaching prey or predators. By outsourcing its acoustic sensors to its web, the spider is released from body size constraints and permits the araneid spider to increase its sound-sensitive surface area enormously, up to 10,000 times greater than the spider itself. The spider also enables the flexibility to functionally adjust and regularly regenerate its "external eardrum" according to its needs. The "outsourcing" and "supersizing" of auditory function in spiders provides unique features for studying extended and regenerative sensing, and designing novel acoustic flow detectors for precise fluid dynamic measurement and manipulation.
Most existing channel pruning methods formulate the pruning task from a perspective of inefficiency reduction which iteratively rank and remove the least important filters, or find the set of filters that minimizes some reconstruction errors after pruning. In this work, we investigate the channel pruning from a new perspective with statistical modeling. We hypothesize that the number of filters at a certain layer reflects the level of 'redundancy' in that layer and thus formulate the pruning problem from the aspect of redundancy reduction. Based on both theoretic analysis and empirical studies, we make an important discovery: randomly pruning filters from layers of high redundancy outperforms pruning the least important filters across all layers based on the state-of-the-art ranking criterion. These results advance our understanding of pruning and further testify to the recent findings that the structure of the pruned model plays a key role in the network efficiency as compared to inherited weights.
Decent Work Pant I have two pair of this pant. One pair I bought in the store to give them a try. I liked them well enough to order another pair here on Amazon. The second pair I received were identical (other than color) than the store bought pair, except the fit much tighter. I suspect that the pair I ordered were mis-labeled at the factory. They fit like they are one size smaller than the label indicates
Angle-resolved second harmonic generation (SHG) spectra of ZnO microwires show characteristic Fano resonances in the spectral vicinity of exciton-polariton modes. The output SHG spectra after SHG interacting with exciton polariton shows a resonant enhancement peak accompanied by a suppression dip originating from the constructive and destructive interference respectively. It is demonstrated that the Fano line shape, and thus the Fano asymmetry parameter q, can be tuned by the phase-shift of the two channels. The phase-dependent q was calculated and the model describes our experimental results well. In particular, the phase-to-q relation unveil the crucial information about the dynamics of the system, e.g., defining the line shape of output SHG spectra in a superposition of quantum states.
With contemporary infrared spectroscopic surveys like APOGEE, red-giant stars can be observed to distances and extinctions at which Gaia parallaxes are not highly informative. Yet the combination of effective temperature, surface gravity, composition, and age - all accessible through spectroscopy - determines a giant's luminosity. Therefore spectroscopy plus photometry should enable precise spectrophotometric distance estimates. Here we use the APOGEE-Gaia-2MASS-WISE overlap to train a data-driven model to predict parallaxes for red-giant branch stars with $0<\log g\leq2.2$ (more luminous than the red clump). We employ (the exponentiation of) a linear function of APOGEE spectral pixel intensities and multi-band photometry to predict parallax spectrophotometrically. The model training involves no logarithms or inverses of the Gaia parallaxes, and needs no cut on the Gaia parallax signal-to-noise ratio. It includes an L1 regularization to zero out the contributions of uninformative pixels. The training is performed with leave-out subsamples such that no star's astrometry is used even indirectly in its spectrophotometric parallax estimate. The model implicitly performs a reddening and extinction correction in its parallax prediction, without any explicit dust model. We assign to each star in the sample a new spectrophotometric parallax estimate; these parallaxes have uncertainties of a few to 15 percent, depending on data quality, which is more precise than the Gaia parallax for the vast majority of targets, and certainly any stars more than a few kpc distance. We obtain 10-percent distance estimates out to heliocentric distances of $20\,$kpc, and make global maps of the Milky Way's disk.
We investigate Higgs-radion mixing scenario through single radion photoproduction process $pp\to p\gamma p\to pRqX$ at the LHC where $X$ represents the remnants of one of the initial protons. We consider high luminosity values of $L_{int}=200\;fb^{-1}$, $500\;fb^{-1}$ and $3000\;fb^{-1}$. We obtain bounds on the mixing parameter space by considering $R\to \gamma\gamma$, $R\to W^+ W^-$ and $R\to ZZ$ decay channels of the radion as the signal. We also perform a similar analysis for a 100 TeV future proton-proton collider and compare its potential with that of LHC.
In natural language processing, word-sense disambiguation (WSD) is an open problem concerned with identifying the correct sense of words in a particular context. To address this problem, we introduce a novel knowledge-based WSD system. We suggest the adoption of two methods in our system. First, we suggest a novel method to encode the word vector representation by considering the graphical semantic relationships from the lexical knowledge-base. Second, we propose a method for extracting the contextual words from the text for analyzing an ambiguous word based on the similarity of word vector representations. To validate the effectiveness of our WSD system, we conducted experiments on the five benchmark English WSD corpora (Senseval-02, Senseval-03, SemEval-07, SemEval-13, and SemEval-15). The obtained results demonstrated that the suggested methods significantly enhanced the WSD performance. Furthermore, our system outperformed the existing knowledge-based WSD systems and showed a performance comparable to that of the state-of-the-art supervised WSD systems.
Burlinson and Thornton give an outstanding performance in this movie, along with Dennehy. Although it is at first thought to be only about love, it really goes down deeper than that. The beauty of nature captures this movie, placing among one of the best I have ever seen. The horse scenes are absolutely fantastic!! Any horse-lovers out there will love this movie!<br /><br />
TANAMI (Tracking Active Galactic Nuclei with Austral Milliarcsecond Interferometry) is a monitoring program to study the parsec-scale structures and dynamics of relativistic jets in active galactic nuclei (AGN) of the Southern Hemisphere with the Long Baseline Array and associated telescopes. Extragalactic jets south of -30 degrees declination are observed at 8.4 GHz and 22 GHz every two months at milliarcsecond resolution. The initial TANAMI sample is a hybrid radio and gamma-ray selected sample since the combination of VLBI and gamma-ray observations is crucial to understand the broadband emission characteristics of AGN.
Just kidding, I rented 12 Monkeys the other day because I am a huge Bruce Willis fan and I heard some things about the film. Some good and some bad, but it was one of those films you had to pay attention to every second, so I was a bit worried. Just because I felt like for a minute if this was going to be one of those films that I had to watch several times to get. But I watched it last night and I was really impressed, this movie had everything in it: action, drama, sci-fi, history, dark humor, and even a little romance. The actors all did a terrific job, I give a lot of credit to Bruce, during his scene in the car with his psychiatrist, he really got to me. But Brad Pitt, I'm just amazed with how much of a great job he did. He didn't over do his character, who was crazy, and just made it work and was extremely believable. The story was just scary, but very good and a wake up call.<br /><br />James Cole is a man in the future where a virus broke out in the past and killed 5 billion people and only 1% of the population survived including him. Animals are now ruling the ground above while the humans are down below, but scientists send James to the past of 1990(really meaning to send him to '96), to find out about information of the virus. James gets put into a mental institution meeting his new psychiatrist, Dr. Kathryn Raily and another mental patient, Jeffrey Goines. He tells them the future, of course no one believes him, he goes back to the future. But the scientists send him back to the correct year to where the doctor is kidnapped by James, but he tells her more, and believes him. Now they are set on trying to prevent the virus from ever happening.<br /><br />12 Monkeys was an incredible film. Like I said the story was so scary just because it's not at all hard to believe that we are not far from that happening. But the whole movie was just great, the cast, the sets, just the whole picture was a great one. It had a Terminator type of feel to it where we might loose something precious one day, ourselves if we don't listen to others. What is right and what is wrong? Who knows? But I would highly recommend 12 Monkeys, it's a great movie that if you give it the proper chance, I'm sure you'll enjoy it.<br /><br />9/10
"The RMS ""Lancastria"" was the subject of the worst single loss of life in British maritime history and the bloodiest single engagement for UK forces in World War II; she was sunk by German bombers on 17 June 1940 when taking part in an operation to evacuate 150,000 troops from where?"
Dogs loved them so much they were destroyed in 4 hours. My dogs love these! Of all the toys they have, I would say these are their favorite. In fact, the dogs liked them so much that they destroyed them by the end of the first night. I have 3 dogs, and the pack came with 3 balls. All three were torn apart within 4 hours. So unfortunately, my review is bad because it sucks to spend $20 on a toy that doesn't make it through the night.
In recent years, the Tian-Zelditch asymptotic expansion for the equivariant components of the Szeg\"{o} kernel of a polarized complex projective manifold, and its subsequent generalizations in terms of scaling limits, have played an important role in algebraic, symplectic, and differential geometry. A natural question is whether there exist generalizations in which the projector onto the spaces of holomorphic sections can be replaced by the projector onto more general (non-complete) linear series. One case that lends itself to such analysis, and which is natural from the point of view of geometric quantization, is given by the linear series determined by imposing spectral bounds on an invariant self-adjoint Toeplitz operator. In this paper we focus on the asymptotics of the spectral projectors associated to slowly shrinking spectral bands.
HORRIBLE Representation! What an absolute waste of $8. I understand "you get what you paid for" in terms of quality, but given this company does business through Amazon, I expected MUCH better than the crap I received. I threw out 8 of the 12 pairs as completely worthless. I'm not even sure the 4 I kept will survive more than one wearing. Never again. And Amazon, you ought to be ashamed for attaching your name to such a load of manure. If I can't trust you with 'fashion' jewelry, what makes you think I'd ever trust you for the REAL???
Lorentz's reciprocity lemma and Feld-Tai reciprocity theorem show the effect of interchanging the action and reaction in Maxwell's equations. We derive a free-space version of these reciprocity relations which generalizes the conservation of the momentum-energy tensor. This relation corresponds to the interference conservation of electromagnetic waves. We show that for any transformation or symmetry that leaves Maxwell's equations invariant, we can modify the reciprocity relation to introduce a conserving density, optical flux and stress tensor extending Noether's theorem to a different context. We apply this method to transformations that can be expressed as Hermitian operators and more specifically we define the operators associated with the optical energy, spin, linear and angular momentum.
Ermakov systems have attracted enormous treatments in recent times particularly in symmetry analysis. In this paper we consider three classes of the Ermakov systems by using a simple algebraic reduction process with imposed conditions on the magnitude of the angular momentum of each system class to obtain new generalized symmetries. We note that this imposed condition transforms the Kepler-Ermakov systems to the generalized Ermakov systems.
In the leader-follower approach, one or more agents are selected as leaders who do not change their states or have autonomous dynamics and can influence other agents, while the other agents, called followers, perform a simple protocol based on the states of their neighbors. This approach provides a natural link between control theory and networked agents with their input data. Despite the fact that the leader-follower approach is widely used, the fundamental question still remains: how to choose leaders from a set of agent. This question is called the problem of choosing leaders. There is still no selection algorithm that is both optimal under a natural criterion and fast. In this paper, for agents that obey a linear consensus protocol, we propose to choose leaders using graph nodes' clustering algorithms and show that this method is the most accurate among the fast existing algorithms of choosing leaders.
The exact solutions of spherically symmetric space-times are explored by using Noether symmetries in $f(R,\phi,X)$ gravity with $R$ the scalar curvature, $\phi$ a scalar field and $X$ the kinetic term of $\phi$. Some of these solutions can represent new black holes solutions in this extended theory of gravity. The classical Noether approach is particularly applied to acquire the Noether symmetry in $f(R,\phi,X)$ gravity. Under the classical Noether theorem, it is shown that the Noether symmetry in $f(R,\phi,X)$ gravity yields the solvable first integral of motion. With the conservation relation obtained from the Noether symmetry, the exact solutions for the field equations can be found. The most important result in this paper is that, without assuming $R=\textrm{constant}$, we have found new spherically symmetric solutions in different theories such as: power-law $f(R)=f_0 R^n$ gravity, non-minimally coupling models between the scalar field and the Ricci scalar $f(R,\phi,X)=f_0 R^n \phi^m+f_1 X^q-V(\phi)$, non-minimally couplings between the scalar field and a kinetic term $f(R,\phi,X)=f_0 R^n +f_1\phi^mX^q$ , and also in extended Brans-Dicke gravity $f(R,\phi,X)=U(\phi,X)R$. It is also demonstrated that the approach with Noether symmetries can be regarded as a selection rule to determine the potential $V(\phi)$ for $\phi$, included in some class of the theories of $f(R,\phi,X)$ gravity.
Jenny Neumann (from the sexploitation flick MISTRESS OF THE APES, the American slasher HELL NIGHT and others) is Helen Selleck, an American actress who gets a lead role in an Australian stage production. She's a virgin because as a little girl she saw her mom having sex and then accidentally caused the car accident that killed her. Meanwhile, a black-gloved killer prowls around the theater slashing up people with shards of glass.<br /><br />*MAJOR SPOILER*<br /><br />The killer is obviously Helen (she speaks in her dead mother's voice, washes blood off her hands after the murders and is seen killing a child molester with a broken bottle as a little girl!), but this has gratuitous heavy-breathing POV camera-work and conceals the identity of the murderer until the very end like it's supposed to be some big surprise.<br /><br />The entire cast seems obsessed with talking about, having or trying to have sex, and, in one case, even blackmailing their way into getting laid. There's quite a bit of nudity and blood, but there's no sense of continuity, the photography is murky and the editing (by Colin Eggleston, who also scripted and produced) is terrible. The theater setting for a slasher film predates Soavi's film of the same name and Argento's OPERA (both of which are better than this one ) by five years though, and Neumann is pretty hot.
Susceptibility measurements of patterned thin films at sub-K temperatures were carried out using a scanning SQUID microscope that can resolve signals corresponding to a few hundred Bohr magnetons. Several metallic and insulating thin films, even oxide-free Au films, show a paramagnetic response with a temperature dependence that indicates unpaired spins as the origin. The observed response exhibits a measurable out-of-phase component, which implies that these spins will create 1/f-like magnetic noise. The measured spin density is consistent with recent explanations of low frequency flux noise in SQUIDs and superconducting qubits in terms of spin fluctuations, and suggests that such unexpected spins may be even more ubiquitous than already indicated by earlier measurements. Our measurements set several constraints on the nature of these spins.
We describe a versatile planar Penning trap structure, which allows to dynamically modify the trapping conguration almost arbitrarily. The trap consists of 37 hexagonal electrodes, each with a circumcirle-diameter of 300 m, fabricated in a gold-on-sapphire lithographic technique. Every hexagon can be addressed individually, thus shaping the electric potential. The fabrication of such a device with clean room methods is demonstrated. We illustrate the variability of the device by a detailed numerical simulation of a lateral and a vertical transport and we simulate trapping in racetrack and articial crystal congurations. The trap may be used for ions or electrons, as a versatile container for quantum optics and quantum information experiments.
How could they take such a beautifully animated gem like Don Bluth's All Dogs go to Heaven and bastardize it with a charmless, cheesy, uninspired sequel. The haunting music and delightful characters are gone, now replaced with tacky animation and an unimaginative plot.<br /><br />The Pros: Charlie Sheen is sometimes fun as Charlie, but he lacks the charming tough guy attitude that brought him to life by Burt Reynolds. I did particularly enjoy the songs "I will always be with you" and "It's too Heavenly here".<br /><br />The Cons: There seems to be no connection between this and the original. In the beginning Charlie is chums with Carface, but wait a minute. Isn't this the same character who was responsible for Charlie's murder and kidnapped the sweet little orphan he loved? I guess that all changes in Heaven but why isn't Anne-Marie even mentioned? If Itchy makes it to Heaven, wouldn't Flo and Killer make it too? What is with Annabelle the whippet's voice? In the original it sounded feminine and charming and in the sequel it sounds like a whiny, bitchy, parrot. The new characters aren't all that great (except Sasha). And the animation is better compared to a generic Saturday morning cartoon. The constant cartoony "humor" is flat and unfunny and the "heart" just doesn't work when compare to the original, which had such a moving unsubtle touch that makes me cry every time.<br /><br />All Dogs go to Heaven is one of my all-time favorite films. How Don Bluth allowed this sequel to be made is beyond me.<br /><br />BOTTOM LINE: Not all sequels go to Heaven.
Nice at first- Does not last Overall, great purchase. I had been looking for a while for a band decently priced for the gear fit 2 pro. Comfort is great, no hair snags yet. The edges are clean. I have only had for one week but the finish is holding up nicely. Wear every day for the most part, most of the day. Great purchase, as there were no reviews wanted to provide something for others. *** UPDATE 6 WEEKS later, product broke, band slipped out of watch connection. Started to fade shortly after this review. Overall don't waste your money, unless you're looking for a band that will last you about 2-3 months
We present a novel thermodynamically guided, low-noise, time-scale bridging, and pertinently efficient strategy for the dynamic simulation of microscopic models for complex fluids. The systematic coarse-graining method is exemplified for low-molecular polymeric systems subjected to homogeneous flow fields. We use established concepts of nonequilibrium thermodynamics and an alternating Monte-Carlo--molecular dynamics iteration scheme in order to obtain the model equations for the slow variables. For chosen flow situations of interest, the established model predicts structural as well as material functions beyond the regime of linear response. As a by-product, we present the first steady state equibiaxial simulation results for polymer melts. The method is simple to implement and allows for the calculation of time-dependent behavior through quantities readily available from the nonequilibrium steady states.
Thanks for the tip, Chuck! Based on a friend's recommendation, I've been using Topo Maps + (free, downloadable topo maps you can use offline). Directionality is the tiniest bit off, but about 99% of the way there. I'd be interested in comparing how it stacks up against MotionX-GPS — there are so many navigational apps out there, I only listed Gaia because it appears to be one of the most popular.
Web service technology has gained more important role in developing distributed applications and systems on the Internet. Rapid growth of published Web services makes their discovery more and more difficult. There exist many web services which exhibit similar functional characteristics. It is imperative to provide service consumers with facilities for selecting required web services according to their non-functional characteristics or QoS. The QoS-based web service discovery mechanisms will play an essential role in SOA, as e-Business applications want to use services that most accurately meet their requirements. However, representing and storing the values of QoS attributes are problematic, as the current UDDI was not designed to accommodate these emerging requirements. To solve the problems of storing QoS in UDDI and aggregating QoS values using the tModel approach. The aim is to study these approaches and other existing QoS tModel representation for their efficiency and consistency in service discovery. This paper discusses a broad range of research issues such as web service discovery or web service selection based on QoS in the E-Business domain.
Orbital angular momentum (OAM) of photons is carried upon the wave front of an optical vortex and is important in physics research due to its fundamental degree of freedom. As for the interaction with materials, the optical OAM was shown to be transferred to the valence electron based on modified selection rules where a single ion is carefully aligned to the center of a vortex [Schmiegelow et al.(2016)]. We here demonstrate an elaborate way of extracting the distributed OAMs in the two-dimensional x-ray wave field at the exit-face of the specimen by a vorticity-sensitive microscopy, which detects vorticity in the reciprocal-space wave field downstream of the optical vortices. This method enables us to measure the distributed topological charges and OAMs by a single image with the wide field of view over 300 $\mu$m. Among various wavelength, the research of x-ray OAM is especially interesting since it could be closely related to the predicted OAM-induced x-ray dichroism [Veenendaal et al.(2007)].
Cheap socks from Adidas. Worn once, washed once ... Cheap socks from Adidas. Worn once, washed once, and fibers are broken all over the sock from the top of the foot to the heel to the top of the sock itself. I'll probably get two more wears from these socks...if I don't bother to wash them again. Cost was less than $10 but the socks aren't worth $5.
High energy inclusive hadron production in the central kinematical region is analyzed within the models of unitarized pomeron. It is shown that the sum of multipomeron exchanges with intercept $\alpha_P(0)>1$ reproduce qualitatively contribution of the triple pole (at $t=0$) pomeron to inclusive cross section. Basing on this analogy we then suggest a general form of unitarized pomeron contributions (in particular the dipole or tripole pomeron) to inclusive cross section. They lead to a parabolic form of the rapidity distribution giving $<n>\propto \ln^3s$ (tripole) or $<n>\propto \ln^2s$ (dipole). The models considered with suggested parametrization of $p_t$-dependence for cross sections well describe the rapidity distributions data in $pp$ and $\bar pp$ interactions at energy $\sqrt{s}\geq 200$ GeV. The predictions for one particle inclusive production at LHC energies are given.
We demonstrate ultrashort pulse generation from a fluoride fiber laser co-doped with holmium and praseodymium. To date the majority of work focused on short pulse generation from this class of fiber laser has employed loss modulators in the cavity, both real and artificial. In this work we alternatively employ a frequency shifting element: an acousto-optic modulator (AOM) in the cavity. This results in mode-locked output of sub-5 ps pulses with 10 nJ of energy at a center wavelength of 2.86 {\mu}m, and a pulse repetition frequency of 30.1 MHz, equating to a peak power of 1.9 kW. Additional experimental investigation of the relationship between frequency shift and cavity round trip offer insight into the complex underlying dynamics. As a complementary mode-locking technique to conventional loss modulation, this method of pulse formation may greatly expand the design flexibility of pulsed mid-infrared fiber lasers.
While sleeping, Mr. Eko is assigned by his brother Yemi (Adetokumboh McCormack) in a dream to go with John Locke to disclose the meaning of the "?" symbol. With the pretext of chasing Henry, Mr. Eko brings John with him and they find a second hatch called "Pearl" underground the question mark symbol marked on the field, where a video explains that the other hatch is a psychological experiment and people behavior pressing the buttons of the computer every 108 minutes are actually subjects. Meanwhile, Jack unsuccessfully tries to save Libby.<br /><br />In this episode, John Locke loses his faith in the island when he finds that they have been monitored in the hatch. The disgusting Michael sees the anguishing Libby wishing that she was dead, while Hurley, Jack, Kate and Sawyer are suffering her pain, in a deep emotional contrast. My vote is eight.<br /><br />Title (Brazil): Not Available
Turning my ears black The ear rings came in very cute packaging. But what I’m concerned with is that they are turning black and turning my ears black. I ordered these because it says they are sterling silver so I thought that they wouldn’t turn my ears any color. They are a super cute design but not something I can wear on a regular basis because of the quality.
You get what you pay for. Not very good quality. I have purchased 2 of these over the past few years. The first set lasted 2 years with frequent Mic use. I bought a second pair 2 months ago only to have the mic stop working within the last week. The mic itself has lots of echo so I would not recommend it for Discord use. The on and off switch also begins to deteriorate after frequent use with audio from the mic being captured regardless of what mode it is on. While the price is enticing I'd recommend spending your money on a head set that is built to last because with this one you really get what you pay for.
Searches are performed for both prompt-like and long-lived dark photons, $A'$, produced in proton-proton collisions at a center-of-mass energy of 13 TeV. These searches look for $A'\!\to\!\mu^+\mu^-$ decays using a data sample corresponding to an integrated luminosity of 5.5/fb collected with the LHCb detector. Neither search finds evidence for a signal, and 90% confidence-level exclusion limits are placed on the $\gamma$-$A'$ kinetic-mixing strength. The prompt-like $A'$ search explores the mass region from near the dimuon threshold up to 70 GeV, and places the most stringent constraints to date on dark photons with $214 < m(A') \lesssim 740$ MeV and $10.6 < m(A') \lesssim 30$ GeV. The search for long-lived $A'\!\to\!\mu^+\mu^-$ decays places world-leading constraints on low-mass dark photons with lifetimes $\mathcal{O}(1)$ ps.
“No Freakin’ battery”!!!!!!! I did a lot of shopping around and decided on this light because it was the cheapest of the ones with the features I wanted. Not till it arrived with no battery did I find in listing that battery was not included. Perhaps that’s my fault because I didn’t read thoroughly, but I am still pissed because now I have the light I wanted but still can’t use it till I spend more money
This film is roughly what it sounds like: a futuristic version of the Cinderella legend but with songs and (fairly tame) sex scenes! The film is not sure what it wants to be and pretty much ends up a mess. It's more expensive looking than most of director Al Adamson's films but it's not at the same budget level that viewers have come to expect from sci-fi films. The actors are pretty bad and unlike most Adamson films, there are no former big namers or B actors. Some of the music is OK but it's easy to see why Cinderella 2000 has been forgotten for so many years.
This expository review is devoted to fish swimming and bird/insect flight. (i) The simple waving motion of an elongated flexible ribbon plate of constant width, immersed in a fluid at rest, propagating a wave distally down the plate to swim forward is first considered to provide a fundamental concept on energy conservation. It is generalized to include variations in body width and thickness, vortex shedding from appended dorsal, ventral and caudal fins to closely simulate fish swimming for which a nonlinear theory is presented for large-amplitude propulsion. (ii) For bird flight, the pioneering studies on oscillating rigid wings are briefed, followed by presenting a nonlinear unsteady theory for flexible wing with arbitrary variations in shape and trajectory with a comparative study with experiments. (iii) For insect flight, more recent advances are reviewed under aerodynamic theory and modeling, computational methods, and experiments, on forward and hovering flights with producing leading-edge vortex to give unsteady high lift. (iv) Prospects are explored on extracting intrinsic flow energy by fish and bird to gain thrust for propulsion. (v) The mechanical and biological principles are drawn together for unified studies on the energetics in deriving metabolic power for animal locomotion, leading to a surprising discovery that the hydrodynamic viscous drag on swimming fish is largely associated with laminar boundary layers, thus drawing valid and sound evidences for a resolution to the fish-swim paradox proclaimed by Gray (1936, 1968).
You could pretty much put on a pair of winter gloves and ... This product is absolutely bullshit. You can not even grab a cookie sheet out of the oven that has been baking at 350 degrees without getting burned. You could pretty much put on a pair of winter gloves and be better off. A complete and utter waste of money. Extremely disappointing! The description states 932 degrees F????!!!!
Notes of lectures for graduate students that were given at Lake Como in 1999, covering the theory of linearized gravitational waves, their sources, and the prospects at the time for detecting gravitational waves. The lectures remain of interest for pedagogical reasons, and in particular because they contain a treatment of current-quadrupole gravitational radiation (in connection with the r-modes of neutron stars) that is not readily available in other sources.
We prove a general theorem that gives a non trivial relation in the group of derived autoequivalences of a variety (or stack) X, under the assumption that there exists a suitable functor from the derived category of another variety Y admitting a full exceptional sequence. Applications include the case in which X is Calabi-Yau and either X is a hypersurface in Y (this extends a previous result by the author and R.L. Karp, where Y was a weighted projective space) or Y is a hypersurface in X. The proof uses a resolution of the diagonal of Y constructed from the exceptional sequence.
The question of encoding movements such as those produced by human gestures may become central in the coming years, given the growing importance of movement data exchanges between heterogeneous systems and applications (musical applications, 3D motion control, virtual reality interaction, etc.). For the past 20 years, various formats have been proposed for encoding movement, especially gestures. Though, these formats, at different degrees, were designed in the context of quite specific applications (character animation, motion capture, musical gesture, biomechanical concerns...). The article introduce a new file format, called GMS (for 'Gesture and Motion Signal'), with the aim of being more low-level and generic, by defining the minimal features a format carrying movement/gesture information needs, rather than by gathering all the information generally given by the existing formats. The article argues that, given its growing presence in virtual reality situations, the "gesture signal" itself must be encoded, and that a specific format is needed. The proposed format features the inner properties of such signals: dimensionality, structural features, types of variables, and spatial and temporal properties. The article first reviews the various situations with multisensory virtual objects in which gesture controls intervene. The proposed format is then deduced, as a mean to encode such versatile and variable "gestural and animated scene".
We present results from long-term optical photometric and spectroscopic observations of 5 pre-main sequence stars, located in the vicinity of the bight nebula NGC 7129. We obtained UBVRI photometric observations in the field centered on the star V391 Cep, north-west of the bright nebula NGC 7129. Our multicolor CCD observations spanned the period from February 1998 to November 2016. At the time of our photometric monitoring, a total of thirteen medium-resolution optical spectra of the stars were obtained. The results from our photometric study show that all stars exhibit strong variability in all optical passbands. Long-term light curves of the five stars indicate the typical of classical T Tauri stars variations in brightness with large amplitudes. We did not find any reliable periodicity in the brightness variations of all five stars. The results from spectral observations showed that all studied stars can be classified as a classical T Tauri stars with reach emission line spectra and strong variability in the profiles and intensity of emission lines.
We provide a moment map interpretation for the coupled K\"ahler-Einstein equations introduced by Hultgren and Witt Nystr\"om, and in the process introduce a more general system of equations, which we call coupled cscK equations. A differentio-geometric formulation of the corresponding Futaki invariant is obtained and a notion of K-polystability is defined for this new system. Finally, motivated by a result of Sz\'ekelyhidi, we prove that if there is a solution to our equations, then small K-polystable perturbations of the underlying complex structure and polarizations also admit coupled cscK metrics.
The interplay between two-dimensional percolation growth models and one-dimensional particle processes has been a fruitful source of interesting mathematical phenomena. In this paper we develop a connection between the construction of Busemann functions in the Hammersley last-passage percolation model with i.i.d. random weights, and the existence, ergodicity and uniqueness of equilibrium (or time-invariant) measures for the related (multi-class) interacting fluid system. As we shall see, in the classical Hammersley model, where each point has weight one, this approach brings a new and rather geometrical solution of the longest increasing subsequence problem, as well as a central limit theorem for the Busemann function.
Wynne will not be cutting health care spending before the elections, she will do it after because it's not a popular choice. She already has a new source of income from carbon tax to cover the shortage until that time, so she will be balancing the books before the elections from our pockets.
We present \texttt{ESpinS} (Esfahan Spin Simulation) package to evaluate the thermodynamic properties of spin systems described by a spin model Hamiltonian. In addition to the Heisenberg exchange term, the spin Hamiltonian can contain interactions such as bi-quadratic, Dzyaloshinskii-Moriya, and single-ion anisotropy. By applying the classical Monte-Carlo simulation, \texttt{ESpinS} simulates the behavior of spin systems versus temperature. \texttt{ESpinS} ables to calculate the specific heat, susceptibility, staggered magnetization, energy histogram, fourth-order Binder cumulants, and the neutron scattering structure factor. Further, it can compute the user-defined magnetic order parameter i.e. summation of projection of spins on the user-defined directions and the physical quantities based on it. \texttt{ESpinS} works by either local update algorithm or parallel tempering algorithm. The latter feature is an appropriate option for considering the frustrated and spin glass magnetic systems. \texttt{ESpinS} is written in Fortran 90 and can be run in single or parallel mode. The package is freely available under the GPL license (see https://github.com/nafiserb/ESpinS ).
The reversible kinetics of copolymerization is solved analytically for the multistate mechanism proposed by B. D. Coleman and T. G. Fox [J. Chem. Phys. 38, 1065 (1963)] under low conversion conditions where the concentrations of monomeric species are chemostatted and stay constant in time. Although the rates of this mechanism only depends on the currently attached or detached monomer, the growing macromolecular chain forms a nonMarkovian sequence that is characterized by matrices associated with every monomeric unit composing the sequence. These matrices are obtained by solving the kinetic equations and they determine the growth velocity of the copolymers, the statistical properties of its possible sequences, as well as the thermodynamics of the copolymerization process.
The other viewpoint illustrated by the rapporteur' s initial statement and shared by a number of members is to promote regulations and codes of conduct which are needed in order to establish among insurers ways of organising costs on a mutual basis providing everybody with guaranteed access to high-quality care and to counter the risk of discriminatory practices developing together with risk and client selection.
We are investigating mass fractions on the crust of a neutron star which would remain after one year of cooling. We use cooling curves corresponding with various densities, or depths, of the neutron star just after its formation. We assume the modified Urca process dominates the energy budget of the outer layers of the star in order to calculate the temperature of the neutron star as a function of time. Using a nuclear reaction network up to technetium, we calculate how the distribution of nuclei quenches at various depths of the neutron star crust. The initial results indicate that $^{28}$Si is the lightest isotope to be optically thick on the surface after one year of cooling.
Bitmap indexes must be compressed to reduce input/output costs and minimize CPU usage. To accelerate logical operations (AND, OR, XOR) over bitmaps, we use techniques based on run-length encoding (RLE), such as Word-Aligned Hybrid (WAH) compression. These techniques are sensitive to the order of the rows: a simple lexicographical sort can divide the index size by 9 and make indexes several times faster. We investigate reordering heuristics based on computed attribute-value histograms. Simply permuting the columns of the table based on these histograms can increase the sorting efficiency by 40%.
Hey Sanders, a free people and a free press don't bow down to titles like 'general.' Where do you think you live, China, Russia? Read some of the history of your own country. Trump said that awful thing, Wilson did not take credit for a building, you are all wrong, they are right, and proto-fascistic sabre-rattling doesn't magically change facts nor change the fact you've hooked your star to a disgrace and earned yourself a grim spot in the history books. Good luck with your legacy projects.
In the emerging field of magnonics, spin waves are considered for information processing and transmission at high frequencies. Towards this end, the manipulation of propagating spin waves in nanostructured waveguides for novel functionality has recently been attracting increasing focus of research. Excitations with uniform magnetic fields in such waveguides favors symmetric spin wave modes with odd quantization numbers. Interference between multiple odd spin wave modes leads to a periodic self-focusing effect of the propagating spin waves. Here we demonstrate, how antisymmetric spin wave modes with even quantization numbers can be induced by local magnetic fields in a well-controlled fashion. The resulting interference patterns are discussed within an analytical model and experimentally demonstrated using microfocused Brillouin light scattering ({\mu}-BLS).
Let $X_\Sigma$ be a complete toric variety. The coherent-constructible correspondence $\kappa$ of \cite{FLTZ} equates $\Perf_T(X_\Sigma)$ with a subcategory $Sh_{cc}(M_\bR;\LS)$ of constructible sheaves on a vector space $M_\bR.$ The microlocalization equivalence $\mu$ of \cite{NZ,N} relates these sheaves to a subcategory $Fuk(T^M_\bR;\LS)$ of the Fukaya category of the cotangent $T^M_\bR$. When $X_\Si$ is nonsingular, taking the derived category yields an equivariant version of homological mirror symmetry, $DCoh_T(X_\Si)\cong DFuk(T^M_\bR;\LS)$, which is an equivalence of triangulated tensor categories. The nonequivariant coherent-constructible correspondence $\bar{\kappa}$ of \cite{T} embeds $\Perf(X_\Si)$ into a subcategory $Sh_c(T_\bR^\vee;\bar{\Lambda}_\Si)$ of constructible sheaves on a compact torus $T_\bR^\vee$. When $X_\Si$ is nonsingular, the composition of $\bar{\kappa}$ and microlocalization yields a version of homological mirror symmetry, $DCoh(X_\Sigma)\hookrightarrow DFuk(T^T_\bR;\bar{\Lambda}_\Si)$, which is a full embedding of triangulated tensor categories. When $X_\Si$ is nonsingular and projective, the composition $\tau=\mu\circ \kappa$ is compatible with T-duality, in the following sense. An equivariant ample line bundle $\cL$ has a hermitian metric invariant under the real torus, whose connection defines a family of flat line bundles over the real torus orbits. This data produces a T-dual Lagrangian brane $\mathbb L$ on the universal cover $T^M_\bR$ of the dual real torus fibration. We prove $\mathbb L\cong \tau(\cL)$ in $Fuk(T^M_\bR;\LS).$ Thus, equivariant homological mirror symmetry is determined by T-duality.
The Imaging Atmospheric Cherenkov Telescope MAGIC I has recently been extended to a stereoscopic system by adding a second 17 m telescope, MAGIC-II. One of the major improvements of the second telescope is an improved camera. The Camera Control Program is embedded in the telescope control software as an independent subsystem. The Camera Control Program is an effective software to monitor and control the camera values and their settings and is written in the visual programming language LabVIEW. The two main parts, the Central Variables File, which stores all information of the pixel and other camera parameters, and the Comm Control Routine, which controls changes in possible settings, provide a reliable operation. A safety routine protects the camera from misuse by accidental commands, from bad weather conditions and from hardware errors by automatic reactions.
In the algebra Sym(gl(m)) we consider Poisson pencils generated by the linear Poisson-Lie bracket {,}_{gl(m)} and that corresponding to the so-called Reflection Equation Algebra. Each bracket of such a pencil has the Poisson center coinciding with that of the bracket {,}_{gl(m)}. Consequently, any bracket from this pencil can be restricted to a generic GL(m)-orbit O in gl(m)*. Quantization of such a restricted bracket can be done in the frameworks of braided affine geometry. In the paper we consider these Poisson structures, their super-analogs as well as their quantum (braided) counterparts. Also, we exhibit some detailed examples.
Without fail, Netflix has become my winding down after a long workday ritual — and while the streaming-induced trance is pleasant at the moment, my bad habit has had an overall negative effect on my well-being. My daily binging has manifested itself into a less productive, less healthy (due to snacking and late nights), and less happy lifestyle. So, I've decided to press pause on my Parks and Recreation marathon and deep-dive into some self-care books post nine-to-five. Instead of catching up with Leslie Knope and the Pawnee gang, I'm investing my time in myself with the following self-help reads. Each will supply me with the tools to live an all-around better life — starting with how I feel about myself.
Imagine a woman alone in a house for forty five minutes in which absolutely nothing happens. Then this goes on twice more. The writing is flat and lifeless, and jokes unfunny, and the bad acting keeps you from caring about any of the characters, even when they battle wolf packs and get beaten up by fraternity goons. Anyone that ranked this movie higher than a two is not fully sane.
I'm always interested to see neglected movies that appear to have good credentials, but in this case the film's neglect appears justified. Evidently based on some actual incidents during WWII, the film just doesn't connect with the viewer for some reason that it is not quite clear to me. One very likely reason is that - in the print I saw on TCM, anyway - none of the scenes where the Germans talked among themselves were given titles. This interesting directorial concept - to let the non-German speaking viewer just guess from "context" what the Germans are saying to each other - is, in my book, an utter flop and helps to lock the viewer out. Also, the way the movie begins - just dropping us into a very confused situation without much setup - is disorienting. Brian Keith is pretty good here, but the reputations of "The Great Escape" and "Stalag 17" will not be challenged by this flick.
What you see is what you get I just wanted a cheap pair of ripped jeans for summer and that's pretty much what I got. Don't buy these expecting them to last through frequent washes or heavy wear and tear though. Mine have been through ONE WASH and they're already splitting at the seam.
We ask what determines the (small) angle of turbulent jets. To answer this question we first construct a deterministic vortex-street model representing the large scale structure in a self-similar plane turbulent jet. Without adjustable parameters the model reproduces the mean velocity profiles and the transverse positions of the large scale structures, including their mean sweeping velocities, in a quantitative agreement with experiments. Nevertheless the exact self similar arrangement of the vortices (or any other deterministic model) necessarily leads to a collapse of the jet angle. The observed (small) angle results from a competition between vortex sweeping tending to strongly collapse the jet and randomness in the vortex structure, with the latter resulting in a weak spreading of the jet.
We present numerical simulations for unpolarized and polarized structure functions in a chiral soliton model. The soliton is constructed self-consistently from quark fields from which the structure functions are extracted. Central to the project is the implementation of regularizing the Dirac sea (or vacuum) contribution to structure functions from first principles. We discuss in detail how sum rules are realized at the level of the quark wave-functions in momentum space. The comparison with experimental data is convincing for the polarized structure functions but exhibits some discrepancies in the unpolarized case. The vacuum contribution to the polarized structure functions is particularly small.
We report on new measurements of the luminosity function (LF) and mass function (MF) of field low-mass dwarfs derived from Sloan Digital Sky Survey (SDSS) Data Release 6 (DR6) photometry. The analysis incorporates ~15 million low-mass stars (0.1 Msun < M < 0.8 Msun), spread over 8,400 square degrees. Stellar distances are estimated using new photometric parallax relations, constructed from ugriz photometry of nearby low-mass stars with trigonometric parallaxes. We use a technique that simultaneously measures Galactic structure and the stellar LF from 7 < M_r < 16. We compare the LF to previous studies and convert to a MF using the mass-luminosity relations of Delfosse et al., 2000. The system MF, measured over -1.0 < log M/Msun < -0.1, is well-described by a log-normal distribution with Mo = 0.25 Msun. We stress that our results should not be extrapolated to other mass regimes. Our work generally agrees with prior low-mass stellar MFs and places strong constraints on future star-formation studies of the Milky Way.
Superpermutations are words over a finite alphabet containing every permutation as a factor. Finding the minimal length of a superpermutation is still an open problem. In this article, we introduce superpermutations matrices. We establish a link between the minimal size of such a matrix and the minimal length of a universal word for the quotient of the symmetric group $S_n$ by an equivalence relation. We will then give non-trivial bounds on the minimal length of such a word and prove that the limit of their ratio when $n$ approaches infinity is 2.
A space-time dependent node separation in Weyl semimetals acts as an axial vector field. Coupled with domain wall motion in magnetic Weyl semimetals, this induces axial electric and magnetic fields localized at the domain wall. We show how these fields can activate the axial (chiral) anomaly and provide a direct experimental signature of it. Specifically, a domain wall provides a spatially dependent Weyl node separation and an axial magnetic field $\textbf{B}_5$, and domain wall movement, driven by an external magnetic field, gives the Weyl node separation a time dependence, inducing an axial electric field $\textbf{E}_5$. At magnetic fields beyond the Walker breakdown, $\textbf{E}_5\cdot\textbf{B}_5$ becomes nonzero and activates the axial anomaly that induces a finite axial charge density -- imbalance in the number of left- and right-handed fermions -- moving with the domain wall. This axial density, in turn, produces, via the chiral magnetic effect, an oscillating current flowing along the domain wall plane, resulting in a characteristic radiation of electromagnetic waves emanating from the domain wall. A detection of this radiation would constitute a direct measurement of the axial anomaly induced by axial electromagnetic fields.
Bwana Devil is reputedly the first major studio, full length feature filmed entirely in the 3D process. Supposedly producer Oboler went to Africa to shoot a different movie, but after hearing the tale of two man-eating lions, terrorizing railway builders, decided on this one. It's a good story too, almost Hemmingway-like; fear, redemption, the great white hunter and all. It's the telling of the story that seems to drag, almost as though filming in the new process was too weighty for the crew. The action scenes are stiff, almost too staged. But these technical problems appear small in light of the film's dramatic conclusion.
For $k\geqslant 1$, denote by $p_k(n)$ the number of partitions of an integer $n$ into $k$-th powers. In this note, we apply the saddle-point method to provide a new proof for the well-known asymptotic expansion of $p_k(n)$. This approach turns out to significantly simplify those of Wright (1934), Vaughan (2015) and Gafni (2016).
Some really good comments here. I think it's important to note that especially outside the US now, this atrocity is still going on in very remote areas of China, South America and Africa. From what I've read, its mostly fundamentalist missionaries like the Baptists who are forcing indigenous people to live in little plywood shacks. They are punished if they are caught singing, dancing or playing a traditional instrument. One can only imagine what else is going on. People would be surprised if they understood the degree that this is happening, and the missionaries are getting away with it because they're remote. This needs to end now.
Leaking from the bottom I really loved this bottle until, whaddya know, it started leaking from the bottom! What a genius design to have an opening at the bottom of a water bottle! Guess I should’ve known, but figured I’d trust the design and give it a shot. Reached out to the company and never heard back.
Reconsider before purchasing I am so disappointed with this product I was very pleased with my previous vivoactive I just wanted a different style of watch to look more feminine while still having a Garmin. And that is about the only good thing about this particular watch it's battery life is horrible any little bump will have the thing flying to a whole different screen I would never buy this product again
We study the one-dimensional (1D) quantum compass model with two independent parameters by means of an exact mapping to the quantum Ising model. This allows us to uncover hidden features of the quantum phase transition in the ordinary one-parameter quantum compass model, showing that it occurs at a multicritical point where a line of first-order transitions intersects a line of second-order symmetry-breaking transitions of Ising type. We calculate the concurrence and the block entanglement entropy in the four ground state phases, and find that these entanglement measures accurately signal the second-order, but not the first-order, transitions.
Fluctuating-charge models are computationally efficient methods of treating polarization and charge-transfer phenomena in molecular mechanics and classical molecular dynamics simulations. They are also theoretically appealing as they are minimally parameterized, with parameters corresponding to the chemically important concepts of electronegativities and chemical hardness. However, they are known to overestimate charge transfer for widely separated atoms, leading to qualitative errors in the predicted charge distribution and exaggerated electrostatic properties. We present the charge transfer with polarization current equilibration (QTPIE) model, which solves this problem by introducing distance-dependent electronegativities. A graph-theoretic analysis of the topology of charge transfer allows us to relate the fundamental quantities of charge transfer back to the more familiar variables that represent atomic partial charges. This allows us to formulate a unified theoretical framework for fluctuating-charge models and topological charge descriptors. We also demonstrate the important role of charge screening effects in obtaining correct size extensivity in electrostatic properties. Analyzing the spatial symmetries of these properties allows us to shed light on the role of charge conservation in the electronegativity equalization process. Finally, we develop a water model for use in classical molecular dynamics simulations that is capable of treating both polarization and charge transfer phenomena.
In the article, we investigate the influence of spring on the large deflections and stability of a spring-hinged cantilever subject to conservative tip force. Using the closed form solution of the equilibrium equation and closed form solution of Jacobi accessory equation, we determine the beam equilibrium forms and their stability. Also, the solution for spring-hinged cantilever bema subject to a follower force is given. Results are present in the graphical and the tabular form.
This paper has been withdrawn because Theorem 21 and Corollary 22 are in error; The modeling idea is OK, but it needs 9-dimensional variables instead of the 8-dimensional variables defined in notations 6.9. Examples of the correct model (with 9-index variables) are: (1) Diaby, M., "Linear Programming Formulation of the Set Partitioning Problem," International Journal of Operational Research 8:4 (August 2010) pp. 399-427; (2) Diaby, M., "Linear Programming Formulation of the Vertex Coloring Problem," International Journal of Mathematics in Operational Research 2:3 (May 2010) pp. 259-289; (3) Diaby, M., "The Traveling Salesman Problem: A Linear Programming Formulation," WSEAS Transactions on Mathematics, 6:6 (June 2007) pp. 745-754.
Let X be a smooth, linearly normal n dimensional complex projective variety. Assume that the projective dual of X has codimension one with defining polynomial D(X). In this paper the log of the norm of D(X) is expressed as the restriction to the Bergman metrics of an energy functional on X. We show how, for smooth plane curves, this energy functional reduces to the standard action functionals of Kahler geometry.
Polycyclic aromatic hydrocarbon (PAH) emission has long been proposed to be a potential star formation rate indicator, as it arises from the photodissociation region bordering the Str\"omgren sphere of young, massive stars. We apply a recently developed technique of mid-infrared spectral decomposition to obtain a uniform set of PAH measurements from Spitzer low-resolution spectra of a large sample of star-forming galaxies spanning a wide range in stellar mass ($M_\star \approx 10^6-10^{11.4}\,M_{\odot}$) and star formation rate ($\sim 0.1- 2000\,M_{\odot}\rm\,yr^{-1}$). High-resolution spectra are also analyzed to measure [Ne II] 12.8 $\mu$m and [Ne III] 15.6 $\mu$m, which effectively trace the Lyman continuum. We present a new relation between PAH luminosity and star formation rate based on the [Ne II] and [Ne III] lines. Calibrations are given for the integrated $5-15$ $\mu$m PAH emission, the individual features at 6.2, 7.7, 8.6, and 11.3 $\mu$m, as well as several mid-infrared bandpasses sensitive to PAH. We confirm that PAH emission is suppressed in low-mass, dwarf galaxies, and we discuss the possible physical origin of this effect.
I am very happy. Before ordering, I looked at customer satisfaction and their comments on this low-end metal detector. After reading a few comments from many different detectors, I decided to choose this one. First of all, it's ahead of schedule, it's a surprise. I checked other people's prices online. It has the highest price / performance ratio. I am very happy.
We consider the initial boundary value problem for the time-fractional diffusion equation with a homogeneous Dirichlet boundary condition and an inhomogeneous initial data $a(x)\in L^{2}(D)$ in a bounded domain $D\subset \mathbb{R}^d$ with a sufficiently smooth boundary. We analyze the homogenized solution under the assumption that the diffusion coefficient $\kappa^{\epsilon}(x)$ is smooth and periodic with the period $\epsilon>0$ being sufficiently small. We derive that its first order approximation has a convergence rate of $\mathcal{O}(\epsilon^{1/2})$ when the dimension $d\leq 2$ and $\mathcal{O}(\epsilon^{1/6})$ when $d=3$. Several numerical tests are presented to show the performance of the first order approximation.
We define the spherical Hecke algebra for an (untwisted) affine Kac-Moody group over a local non-archimedian field. We prove a generalization of the Satake isomorphism for these algebras, relating it to integrable representations of the Langlands dual affine Kac-Moody group. In the next publication we shall use these results to define and study the notion of Hecke eigenfunction for the group $G_{\aff}$
In this paper we propose a new provenance model which is tailored to a class of workflow-based applications. We motivate the approach with use cases from the astronomy community. We generalize the class of applications the approach is relevant to and propose a pipeline-centric provenance model. Finally, we evaluate the benefits in terms of storage needed by the approach when applied to an astronomy application.
PROteolysis Targeting Chimeras (PROTACs) are bifunctional molecules that degrade target proteins through recruiting E3 ligases. However, their application is limited in part because few E3 ligases can be recruited by known E3 ligase ligands. Through competitive activity-based protein profiling, we found that piperlongumine (PL), a natural product, binds multiple E3 ligases. To evaluate whether PL can be used as an E3 ligase ligand, we generated a series of PL and SNS-032 (a selective CDK9 inhibitor) conjugates and found that the lead conjugate 955 can potently degrade CDK9 in a ubiquitin-proteasome dependent manner. In addition, 955 is more potent than SNS-032 against various tumor cells in vitro. Through TurboID-based proteomics and mechanistic studies, we identified KEAP1 as the E3 ligase recruited by PL to degrade CDK9. These findings demonstrate that PL is a novel E3 ligase ligand that can be used to generate potent anticancer PROTACs.
Normally I don't like series at all. They're all to predictable and they tend to become boring and dull very fast.<br /><br />These series however, are well played, the story follows through all episodes and even if you miss one, the story will still be catching your mind.<br /><br />The episodes are all filmed on a hospital and takes you further and further in to the mysteries of dark and old secrets that lies just beneath the surface of the mighty hospital.
I must question how the feedback from users is pertinent to whether decisions made in 2013 to improve the course are still valid. The decline in numbers of players is noted....but no reasoned discussion of why that is occuring. Golf is widely being discussed a dying sport due to changes in demographic and economic forces, issues that are discussed in business and investment publications. Course closures are happening in great numbers all over the country, sports equipment retailers are writing off million$ in stale merchandise and laying off their golf professionals from retail outlets. Four years of change is not trivial in any business cycle and an honest appraisal should take that into account. And rather than a fresh look at the viability we get a questionaire to only the users and not the community who has to foot the bill. Wonderful.
On New Year's eve, the youth skipped their parties and the elderly shun the comfort of watching TV at home, as thousands of people protesting against the Citizenship Amendment Act (CAA) rang in 2020 with the singing of the national anthem at Delhi's Shaheen Bagh. People roamed around the venue and thronged kiosks for chai to bear the winter chill, while many more stayed put under the tarpaulin shed listening to speakers who got on the stage one after the other. Several roamed around waving national flags while others displayed creative placards against the new law and chanted "Aazadi, Aazadi". As the clock struck midnight, the protesting crowd burst into a cheer to greet the fellow protesters the new year, and moments later broke into the national anthem in unison which was followed by the slogan "Inquilab Zindabad". A city-based artist, who identified herself as Phool Kumari, used the platform to also protest against the arrests of some artists in south India who were held by the police over their anti-CAA kolams recently. "We are living in an Orwellian reality. Absurdity is the new normal. The government is using its brute force at wrong places. Arts and protests, in general, should not be held against the citizens," the 26-year-old artist said, busy writing with chalk the captions of the posters that the protesters used at the venue. Shaheen Bagh, near Jamia Millia Islamia university, has been the protest venue for a section of people opposed to the CAA and the NRC since December 15. At Jamia Millia Islamia on Wednesday, Bollywood actress Swara Bhasker and her co-star from 'Raanjhanaa', Mohammed Zeeshan Ayyub, attended a public meeting and lauded the protesters' efforts in continuing the agitation. "We have woken up late but now we have woken up. You have woken up the entire country. We are here to thank you," Swara told the protesters.
The intracellular pathogen Shigella flexneri, which is the causative agent of bacillary dysentery, significantly influences the worldwide implication of diarrheal infections, consequentially causing about 1.1 million deaths each year. Due to a non-availability of an authorized vaccine and the upsurge of multidrug resistance amongst Shigella strains, there has been a huge demand for further genetic analyses which could help in the advancement of new/improved drugs, and finding vaccine candidates against the pathogen. Whilst many features about the invasion of colonic cells by Shigella have been identified, fundamental gaps in information concerning in what way the bacteria transit, survive, and control gene expression, remain. The present study aims to illustrate the role of yfiB gene in Shigella virulence, which is a part of the periplasmic YfiBNR tripartite signaling system. This system is involved in the regulation of cyclic-di-GMP levels inside the bacterial cells, which is a vital messenger molecule impacting varied cellular processes such as biofilm formation, cytotoxicity, motility, synthesis of exopolysaccharide, and other virulence mechanisms like adhesion and invasion of the bacteria. Through a combination of genetic, biochemical, and virulence assays, we show how knocking out the yfiB gene can disrupt the entire YfiBNR system and affect biofilm formation, bacterial invasion, host-surface attachment, and the overall virulence of Shigella. This study eventually improves our understanding of the in-vivo persistence and survival of Shigella, brings light to the c-di-GMP lead regulation of Shigella virulence, and provides a prospective new target to design anti-infective drugs and vaccines against S. flexneri and other bacterial pathogens.
We investigate the use of entropy-regularized optimal transport (EOT) cost in developing generative models to learn implicit distributions. Two generative models are proposed. One uses EOT cost directly in an one-shot optimization problem and the other uses EOT cost iteratively in an adversarial game. The proposed generative models show improved performance over contemporary models for image generation on MNSIT.
Wow, I haven't seen a movie this bad since "Fire Down Below". Wait, that's a Seagal movie too. Like "On Deadly Ground" and "Fire Down Below", Seagal centers the movie around his environmental awareness message and how the military, FBI, and CIA are incompetent idiots. Problem is that both reality and a sensible plot are secondary to whatever gobbleygook social commentary Seagal is trying to get across.
We present the first determination of the Hubble constant $H_0$ from strong lensing time delay data and type Ia supernova luminosity distances that is independent of the cosmological model. We also determine the spatial curvature model-independently. We assume that light propagation over long distances is described by the FLRW metric and geometrical optics holds, but make no assumption about the contents of the Universe or the theory of gravity on cosmological scales. We find $H_0=75.7^{+4.5}_{-4.4}$ km/s/Mpc and $\Omega_{K0}=0.12^{+0.27}_{-0.25}$. This is a 6\% determination of $H_0$. A weak prior from the cosmic microwave background on the distance to the last scattering surface improves this to $H_0=76.8^{+4.2}_{-3.8}$ km/s/Mpc and $\Omega_{K0}=0.18^{+0.25}_{-0.18}$. Assuming zero spatial curvature, we get $H_0=74.2^{+3.0}_{-2.9}$ km/s/Mpc, a precision of $4\%$. The measurements also provide a consistency test of the FLRW metric: we find no evidence against it.
They're great WHEN THEY WORK...and that's the problem... These are great WHEN THEY WORK...and that's the rub....I've now ordered 4 of them and 2 have been returned for the same reason....they both worked one time...then both times the motor ran, but no lights.....again when they work...they're awesome I'll review them again later...
Using numerical simulations, we show that smooth migration of the giant planets through a planetesimal disk leads to an orbital architecture that is inconsistent with the current one: the resulting eccentricities and inclinations of their orbits are too small. The crossing of mutual mean motion resonances by the planets would excite their orbital eccentricities but not their orbital inclinations. Moreover, the amplitudes of the eigenmodes characterising the current secular evolution of the eccentricities of Jupiter and Saturn would not be reproduced correctly; only one eigenmode is excited by resonance-crossing. We show that, at the very least, encounters between Saturn and one of the ice giants (Uranus or Neptune) need to have occurred, in order to reproduce the current secular properties of the giant planets, in particular the amplitude of the two strongest eigenmodes in the eccentricities of Jupiter and Saturn.
This paper considers the problem of resource allocation in stream processing, where continuous data flows must be processed in real time in a large distributed system. To maximize system throughput, the resource allocation strategy that partitions the computation tasks of a stream processing graph onto computing devices must simultaneously balance workload distribution and minimize communication. Since this problem of graph partitioning is known to be NP-complete yet crucial to practical streaming systems, many heuristic-based algorithms have been developed to find reasonably good solutions. In this paper, we present a graph-aware encoder-decoder framework to learn a generalizable resource allocation strategy that can properly distribute computation tasks of stream processing graphs unobserved from training data. We, for the first time, propose to leverage graph embedding to learn the structural information of the stream processing graphs. Jointly trained with the graph-aware decoder using deep reinforcement learning, our approach can effectively find optimized solutions for unseen graphs. Our experiments show that the proposed model outperforms both METIS, a state-of-the-art graph partitioning algorithm, and an LSTM-based encoder-decoder model, in about 70% of the test cases.
The usage of numerical models to study the evolution of particle beams is an essential step in the design process of particle accelerators However, uncertainties of input quantities such as beam energy and magnetic field lead to simulation results that do not fully agree with measurements, hence the final machine will behave slightly differently than the simulations In case of cyclotrons such discrepancies affect the overall turn pattern or may even alter the number of turns in the machine Inaccuracies at the PSI Ring cyclotron facility that may harm the isochronism are compensated by additional magnetic fields provided by 18 trim coils These are often absent from simulations or their implementation is very simplistic In this paper a newly developed realistic trim coil model within the particle accelerator framework OPAL is presented that was used to match the turn pattern of the PSI Ring cyclotron Due to the high-dimensional search space consisting of 48 design variables (simulation input parameters) and 182 objectives (i.e turns) simulation and measurement cannot be matched in a straightforward manner Instead, an evolutionary multi-objective optimisation with a population size of more than 8000 individuals per generation together with a local search approach were applied that reduced the maximum absolute error to 4.54 mm over all 182 turns.
Generalizing the ideas of $\mathbb{Z}_k$-manifolds from Morgan-Sullivan and the theory of stratifolds from Kreck, we define $\mathbb{Z}_k$-stratifolds. We introduce the bordism theory of $\mathbb{Z}_k$-stratifolds in order to represent every homology class with $\mathbb{Z}_k$-coefficients. We present a geometric interpretation of the Bockstein long exact sequences and the Atiyah-Hirzebruch spectral sequence for $\mathbb{Z}_k$-bordism ($k$ an odd number). Finally, we give geometric constructions of the homology classes $H_*(B\mathbb{Z}_p ;\mathbb{Z}_p)$ ($p$ odd prime) in terms of $\mathbb{Z}_k$-stratifolds.
The aim of this paper is to introduce a new design of experiment method for A/B tests in order to balance the covariate information in all treatment groups. A/B tests (or "A/B/n tests") refer to the experiments and the corresponding inference on the treatment effect(s) of a two-level or multi-level controllable experimental factor. The common practice is to use a randomized design and perform hypothesis tests on the estimates. However, such estimation and inference are not always accurate when covariate imbalance exists among the treatment groups. To overcome this issue, we propose a discrepancy-based criterion and show that the design minimizing this criterion significantly improves the accuracy of the treatment effect(s) estimates. The discrepancy-based criterion is model-free and thus makes the estimation of the treatment effect(s) robust to the model assumptions. More importantly, the proposed design is applicable to both continuous and categorical response measurements. We develop two efficient algorithms to construct the designs by optimizing the criterion for both offline and online A/B tests. Through simulation study and a real example, we show that the proposed design approach achieves good covariate balance and accurate estimation.
In theories with discrete Abelian gauge groups, requiring that black holes be able to lose their charge as they evaporate leads to an upper bound on the product of a charged particle's mass and the cutoff scale above which the effective description of the theory breaks down. This suggests that a non-trivial version of the Weak Gravity Conjecture (WGC) may also apply to gauge symmetries that are discrete, despite there being no associated massless field, therefore pushing the conjecture beyond the slogan that `gravity is the weakest force'. Here, we take a step towards making this expectation more precise by studying $\mathbb{Z}_N$ and $\mathbb{Z}_2^N$ gauge symmetries realised via theories of spontaneous symmetry breaking. We show that applying the WGC to a dual description of an Abelian Higgs model leads to constraints that allow us to saturate but not violate existing bounds on discrete symmetries based on black hole arguments. In this setting, considering the effect of discrete hair on black holes naturally identifies the cutoff of the effective theory with the scale of spontaneous symmetry breaking, and provides a mechanism through which discrete hair can be lost without modifying the gravitational sector. We explore the possible implications of these arguments for understanding the smallness of the weak scale compared to $M_{Pl}$.
A theoretical scheme for the analysis of experimental data on IR spectroscopy for a quantum particle in a double well potential (DWP) is suggested. The analysis is based on the trigonometric DWP for which the exact analytic solution of the Schr\"odinger equation is available. The corresponding energy levels along with their wave functions are expressed via special functions implemented in {\sl {Mathematica}} (spheroidal function and its spectrum of eigenvalues). As a result trigonometric DWP makes the calculation of the energy levels an extremely easy procedure. It contains three parameters allowing one to model the most important characteristics of DWP (barrier height and the distance between the minima of the potential) along with the required asymmetry. Our approach provides an accurate calculation of the energy spectrum for hydrogen bonds in chromous acid (CrOOH) and potassium dihydrogen phosphate (${\rm{KH_2PO_4}}$) along with their polarizability in agreement with available experimental data.
