The Spallation Neutron Source (SNS), located at Oak Ridge Laboratory in the United States, will be coming online over the next few years. In addition to producing fluxes of high-intensity neutrons, the interaction of the proton beam with the liquid mercury target produces copious pions. The pi+ and subsequent mu+ decay at rest, providing a neutrino beam comprising numu, nue, and anti-numu components. This neutrino beam is ideal for high-precision neutrino experiments. OscSNS is a proposed multi-purpose experiment that will perform a search for light sterile neutrinos, search for beyond the Standard Model interactions using neutrino oscillations, and provide tests of Standard Model predictions through world-record precision neutrino cross section measurements. OscSNS plans to submit a full proposal for funding in 2009.
Like many other commentators here, I went in expecting a taste of music that would satisfy my curiosity - and got more than I asked for. I heard and saw a powerful, exquisite, sometimes haunting, sometimes touching, lyrical, sentimental (in the truest way) and absolutely stunning blend of music and musicians. Reminded me a lot of some forms of Indian music (East Indian) but at the same time was very very different.<br /><br />Starting from the the first track by Baba Zula to the Kurdish singer Aynur (what a voice) to Siyasiyabend to the jam session (or 'Jugalbandhi ' as we call it in India) in the small Turkish bar ft. Selim Seslar (Big fan now :) ), I enjoyed every minute and wished it wouldn't end.<br /><br />One of the best music commentaries I have seen and heard in a long time. <br /><br />I am craving for a CD of the sound-track and hope I can find it online somewhere soon and also for old and latest albums from Baba Zula.<br /><br />A day later, the music is still etched in my brain and I don't want it to go away. Turkey and specifically Istanbul now seem such beautiful and exciting places - and I am going to start saving today to go take it in.<br /><br />Faith Akin - this is a gem.
Solar flares are extremely energetic phenomena in our Solar System. Their impulsive, often drastic radiative increases, in particular at short wavelengths, bring immediate impacts that motivate solar physics and space weather research to understand solar flares to the point of being able to forecast them. As data and algorithms improve dramatically, questions must be asked concerning how well the forecasting performs; crucially, we must ask how to rigorously measure performance in order to critically gauge any improvements. Building upon earlier-developed methodology (Barnes et al, 2016, Paper I), international representatives of regional warning centers and research facilities assembled in 2017 at the Institute for Space-Earth Environmental Research, Nagoya University, Japan to - for the first time - directly compare the performance of operational solar flare forecasting methods. Multiple quantitative evaluation metrics are employed, with focus and discussion on evaluation methodologies given the restrictions of operational forecasting. Numerous methods performed consistently above the "no skill" level, although which method scored top marks is decisively a function of flare event definition and the metric used; there was no single winner. Following in this paper series we ask why the performances differ by examining implementation details (Leka et al. 2019, Paper III), and then we present a novel analysis method to evaluate temporal patterns of forecasting errors in (Park et al. 2019, Paper IV). With these works, this team presents a well-defined and robust methodology for evaluating solar flare forecasting methods in both research and operational frameworks, and today's performance benchmarks against which improvements and new methods may be compared.
Arguments on PL,(=piecewise linear) topology work over any ordered field in the same way as over the real field, and those on differential topology do over a real closed field R in an o-minimal structure that expands (R,<,0,1,+,cdot). One of the most fundamental properties of definable sets is that a compact definable set in R^n is definably homeomorphic to a polyhedron (see [v]). We show uniqueness of the polyhedron up to PL homeomorphisms (o-minimal Hauptvermutung). Hence a compact definable topological manifold admits uniquely a PL manifold structure and is, so to say, tame. We also see that many problems on PL and differential topology over R can be translated to those over the real field.
Motivated by the realisation of Yang-Baxter equation of 2d Integrable models in the 4d gauge theory of Costello-Witten-Yamazaki (CWY), we study the embedding of integrable 2d Toda field models inside this construction. This is done by using the Lax formulation of 2d integrable systems and by thinking of the standard Lax pair $L_{\pm }$ in terms of components of CWY gauge connection propagating along particular directions in the gauge bundle. We also use results of the CWY theory to build quantum line operators for 2d Toda models and compute the one loop contribution of two intersecting lines exchanging one gluon. Other features like local symmetries and comments on extension of our method to other 2d integrable models are also discussed. We also comment on\textrm{\ }some basic points that still need a refinement before talking about a fully consistent embedding of Lax pairs into CWY theory.
Global pairwise network alignment (GPNA) aims to find a one-to-one node mapping between two networks that identifies conserved network regions. GPNA algorithms optimize node conservation (NC) and edge conservation (EC). NC quantifies topological similarity between nodes. Graphlet-based degree vectors (GDVs) are a state-of-the-art topological NC measure. Dynamic GDVs (DGDVs) were used as a dynamic NC measure within the first-ever algorithms for GPNA of temporal networks: DynaMAGNA++ and DynaWAVE. The latter is superior for larger networks. We recently developed a different graphlet-based measure of temporal node similarity, graphlet-orbit transitions (GoTs). Here, we use GoTs instead of DGDVs as a new dynamic NC measure within DynaWAVE, resulting in a new approach, GoT-WAVE. On synthetic networks, GoT-WAVE improves DynaWAVE's accuracy by 25% and speed by 64%. On real networks, when optimizing only dynamic NC, each method is superior ~50% of the time. While DynaWAVE benefits more from also optimizing dynamic EC, only GoT-WAVE can support directed edges. Hence, GoT-WAVE is a promising new temporal GPNA algorithm, which efficiently optimizes dynamic NC. Future work on better incorporating dynamic EC may yield further improvements.
in continuance: perhaps an example would make this more clear: If you have a female receptionist being refused to speak during board meeting, this is clearly not sexist, because the receptionist, regardless of gender, is not a member of the board and has no right to speak during the meeting. However, if a female board-member is not allowed to voice her opinion during the board meeting and is constantly interrupted by her male colleagues and, if her male colleagues are not treated similarly, one could plausibly claim sexism. If you are to be taken seriously as a writer, you must learn to distinguish between like and unlike scenarios. It may be profitable to try and push a "liberal hypocrisy" narrative, but at least make some attempt at intellectual honesty while doing so.
We give an efficient solution to the following problem: Given $X_1, \ldots X_d$ and $Y$ some $n$ by $n$ matrices can we determine if $Y$ is in the unital algebra generated by $X_1, \ldots, X_d$ as a subalgebra of all $n$ by $n$ matrices? The solution also gives an easy method for computing the dimension of this algebra.
We realize four-dimensional N=2 superconformal quiver gauge theories with alternating SO and USp gauge groups as compactifications of the six-dimensional D_N theory with defects. The construction can be used to analyze infinitely strongly-coupled limits and S-dualities of such gauge theories, resulting in a new class of isolated four-dimensional N=2 superconformal field theories with SO(2N)^3 flavor symmetry.
In IEEE 802.11 Wireless Local Area Networks (WLANs), network nodes experiencing collisions on the shared channel need to backoff for a random period of time, which is uniformly selected from the Contention Window (CW). This contention window is dynamically controlled by the Backoff algorithm. First step to design a an efficient backoff algorithm for multi-hop ad hoc network is to analysis of the existing backoff algorithms in multi-hop ad hoc networks. Thus, in this paper, we considered two important multi-hop adhoc network scenarios: (a) Node Mobility Scenario and (b) Transmission Range Scenario and analyze and evaluate both the impact of mobility (i.e. node speed) and the impact of transmission range of nodes on the performance of various backoff algorithms
I love this shampoo and conditioner I’m rating both the product and the packaging. I love this shampoo and conditioner, my stylist uses it when I visit her at the beauty salon and it leaves my hair super soft and shiny. The packaging however, was bad. I think when packing the product, the shampoo wasn’t closed tight enough and it spilled inside the box. I just washed it off and it was all good. Happy with my product.
Microscopic studies of nuclear matter under diverse conditions of density and asymmetry are of great contemporary interest. Concerning terrestrial applications, they relate to future experimental facilities that will make it possible to study systems with extreme neutron-to-proton ratio. In this talk, I will review recent efforts of my group aimed at exploring nuclear interactions in the medium through the nuclear equation of state (EoS). The approach we take is microscopic and relativistic, with the predicted EoS properties derived from realistic nucleon-nucleon potentials. I will also discuss work in progress. Most recently, we completed a DBHF calculation of the $\Lambda$ hyperon binding energy in nuclear matter.
The performance of a machine learning system is usually evaluated by using i.i.d.\ observations with true labels. However, acquiring ground truth labels is expensive, while obtaining unlabeled samples may be cheaper. Stratified sampling can be beneficial in such settings and can reduce the number of true labels required without compromising the evaluation accuracy. Stratified sampling exploits statistical properties (e.g., variance) across strata of the unlabeled population, though usually under the unrealistic assumption that these properties are known. We propose two new algorithms that simultaneously estimate these properties and optimize the evaluation accuracy. We construct a lower bound to show the proposed algorithms (to log-factors) are rate optimal. Experiments on synthetic and real data show the reduction in label complexity that is enabled by our algorithms.
Traditional grid/neighbor-based static pooling has become a constraint for point cloud geometry analysis. In this paper, we propose DAR-Net, a novel network architecture that focuses on dynamic feature aggregation. The central idea of DAR-Net is generating a self-adaptive pooling skeleton that considers both scene complexity and local geometry features. Providing variable semi-local receptive fields and weights, the skeleton serves as a bridge that connect local convolutional feature extractors and a global recurrent feature integrator. Experimental results on indoor scene datasets show advantages of the proposed approach compared to state-of-the-art architectures that adopt static pooling methods.
Wague returns for Barcelona's final session of the year Barcelona The squad have January 1 off Barcelona trained for the last time in 2019 on Tuesday morning and Moussa Wague took part. Wague had missed out in recent days, battling a dose of conjunctivitis, but he was back to work on New Year's Eve. Ousmane Dembele, Arthur Melo and Marc-Andre ter Stegen all sat out the day's work with injury. Inaki Pena, Ronald Araujo, Oscar Mingueza, Alex Collado, RIqui Puig, Carles Perez and Ansu Fati also took part in the session. The squad will rest on New Year's Day before returning to work on Thursday afternoon at 17:00 CET ahead of their derby with Espanyol on Saturday.
Too bulky Did not like this case. It makes the iPad too bulky with the totally enclosed back. I guess if you want major protection it would be good, but I much prefer the simple magnetic flap that just covers the front. I didn’t want to pay the totally inflated $35 for the simple flap cover, but after I tried this hard plastic case I changed my mind and bought the good one.
The recently discovered correspondence between the distribution of rapidity gaps in electron-nucleus diffractive processes and the statistics of the height of genealogical trees in branching random walks is reviewed. In addition, a new comparison of numerical solutions of exact equations for diffraction on the one hand, and for ancestry on the other hand, both established in the framework of the color dipole model, is presented.
We present an extension of the FKS subtraction scheme beyond next-to-leading order to deal with soft singularities in fully differential calculations within QED with massive fermions. After a detailed discussion of the next-to-next-to-leading order case, we show how to extend the scheme to even higher orders in perturbation theory. As an application we discuss the computation of the next-to-next-to-leading order QED corrections to the muon decay and present differential results with full electron mass dependence.
While the IEEE 802.11 protocol is being widely used, it is not specifically designed to handle multimedia traffic, which covers an important portion of the Internet traffic today. Voice and video multicast streaming is inefficient, as there is lack of transmission reliability in such approaches where delay is not guaranteed. In this work, we focus on the performance of Enhanced Distributed Channel Access (EDCA) mechanism proposed by IEEE 802.11e which provides traffic prioritization and since most of the previous works are done based on simulation results, we test the performance of this protocol in a real platform using sofware Defined Networks. We then validate the impact of different EDCA parameters ( e.g., AIFS and TXOP) by tuning them to see their impact on the delay of the network and eventually on network traffic.
It's just one of those films, you're either love it or hate it, my girlfriend and me loved it, told my brother to rent it and he hated it, said it was too flashy and colloquial, then again he only usually goes to see big action movies, so probably not enough explosions left him disappointed. There were some great new talent (I'd never heard of the leads before anyway)? Des Brady (the directors brother?) was especially good. Playing a right dick at the start I thought he never would redeem himself but he managed to crawl out of the dark hole he had created and by the end I was really routing for him. A very surprising film with a whole lot of heart, if you can live without a body count and explosions then this one is very original. Yashimo. Brixton in the UK.
The title above is used to introduce the film "Gen" to its audience. Gen is about a young doctor(Doga Rutkay) with an ill mother. The film starts with her leaving her mother behind to start her new job. While she drives, we realise that she is not that close home as the hospital is in a remote area. As soon as she steps into the garden of the hospital, she sees the death body of a patient. This is the beginning of a nightmare for the next few days.<br /><br />Two policemen comes to the hospital so as to investigate the suicide. In fact, they will have to stay in the hospital because all roads are cut off due to bad weather conditions. All their communication with outside world is cut off too. There is no way out!! In those few days, there will be more nasty murders. Now everybody suspects from each other.<br /><br />In my opinion, the idea is brilliant. It could have been very scary indeed. There are positive sides of the movie of course. I really like the beginning of the movie. Especially, when she drives to the hospital and her first moments in the hospital. Actings are okay. Some of them are trying too hard to be mysterious and scary though. I think the final shock should have been spread into the through out of the movie. What I am saying is, it was a good twist but instead of showing it as a parody in the end, we should have realised that was coming when we see what is happening. The director needed to explain it altogether which I think didn't work well. Also the most dangerous patient in the movie is supposed to be at least 48 years old but his body looks so young and fit for someone who spends most of his life in this hospital. Lastly, I would like to say a few things about the director. I am sure he will improve. This is his first attempt. I have recently found out that he is only 21 years old. That made me feel more positive about him and his future films. I am not going to rate this film * out of ***** though.
We investigate impact of a sphere onto a floating elastic sheet and the resulting formation and evolution of wrinkles in the sheet. Following impact, we observe a radially propagating wave, beyond which the sheet remains approximately planar but is decorated by a series of radial wrinkles whose wavelength grows in time. We develop a mathematical model to describe these phenomena by exploiting the asymptotic limit in which the bending stiffness is small compared to stresses in the sheet. The results of this analysis show that, at a time $t$ after impact, the transverse wave is located at a radial distance $r\sim t^{1/2}$ from the impactor, in contrast to the classic $r\sim t^{2/3}$ scaling observed for capillary--inertia ripples produced by dropping a stone into a pond. We describe the shape of this wave, starting from the simplest case of a point impactor, but subsequently addressing a finite-radius spherical impactor, contrasting this case with the classic Wagner theory of impact. We show also that the coarsening of wrinkles in the flat portion of the sheet is controlled by the inertia of the underlying liquid: short-wavelength, small-amplitude wrinkles form at early times since they accommodate the geometrically-imposed compression without significantly displacing the underlying liquid. As time progresses, the liquid accelerates and the wrinkles grow larger and coarsen. We explain this coarsening quantitatively using numerical simulations and scaling arguments, and we compare our predictions with experimental data.
We address a problem of generating a robust entangling gate between electronic and nuclear spins in the system of a single nitrogen-vacany centre coupled to a nearest Carbon-13 atom in diamond against certain types of systematic errors such as pulse-length and off-resonance errors. We analyse the robustness of various control schemes: sequential pulses, composite pulses and numerically-optimised pulses. We find that numerically-optimised pulses, produced by the gradient ascent pulse engineering algorithm (GRAPE), are more robust than the composite pulses and the sequential pulses. The optimised pulses can also be implemented in a faster time than the composite pulses.
During winter and springtime, the flow above Antarctica at high altitude (upper troposphere and stratosphere) is dominated by the presence of a vortex centered above the continent. It lasts typically from August to November. This vortex is characterized by a strong cyclonic jet centered above the polar high. In a recent study of our group (Hagelin et al., 2008) of four different sites in the Antarctic internal plateau (South Pole, Dome C, Dome A and Dome F), it was made the hypothesis that the wind speed strength in the upper atmosphere should be related to the distance of the site to the center of the Antarctic polar vortex. This high altitude wind is very important from an astronomical point of view since it might trigger the onset of the optical turbulence and strongly affect other optical turbulence parameters. What we are interested in here is to localize the position of the minimum value of the wind speed at high altitude in order to confirm the hypothesis of Hagelin et al. (2008).
I've only seen about a half dozen films starring Lino Ventura, but this one seems very much like the others. He plays a laconic criminal--one who is short on words and subdued yet occasionally explosive. Given his quiet persona in such films as ARMY OF SHADOWS and SECOND BREATH, I've noticed that his minimalist style of acting is extremely effective. In other words, because he is so quiet and mannered, when he does bad things you tend to notice. And, like these other films, he also has a very strong, though twisted, moral code.<br /><br />Abel Davos (Ventura) and his partner, Lilane, are both living in Italy and are career criminals. Both grew up in France and eventually had to flea due to their criminal activities. Now in Italy as the film begins, they continue to live the life of thugs and the heat is on to catch them. Oddly, instead of running to yet a third country, they decide to go back to France--even though Davos has been tried and convicted in absentia--and if he's caught it could mean a life in prison or the death penalty. Much of the first third of the film concerns their covert return.<br /><br />Unfortunately for Davos, the return doesn't go perfectly and now it seems as if every cop in France is looking for him. Additionally, the reaction of his old compatriots in crime is not at all what he'd expect. In fact, their tepid response to his return ends up unleashing a series of terrible events towards the end of the film.<br /><br />Along the way, Davos meets and is taken in my a stranger, Eric Stark (Jean-Paul Belmondo). Despite Davos seemingly having no friends, Stark and his lady friend try their best to make his return successful. What throws another monkey wrench into this, though, is Davos' two very young sons--what is Davos to do with them--keep them with him in his hiding place? <br /><br />Overall, this is a very good crime film--sort of like French Film Noir. Unlike American Noir, the many French versions I have seen have a more realistic as well as bleak outlook to them. Fatalism reigns supreme, that's for sure! The acting is first-rate (especially from Ventura and Belmondo), the direction very sure and the writing very nice, though I am sure many won't like the ending. It just seems to be tacked on--like an afterthought. I understood why they did it this way, but can also see how it might leave many unsatisfied. As for me, it did leave me a tad flat. Otherwise, an exceptional film.
George Burns returns as the joshing Almighty after enjoying a big success with 1977's "Oh, God!", an upbeat fantasy made successful by a sudden need in the 1970s to switch from devil-driven thrillers to comedic redemption (although it made money, the original was more in line with the "Topper" comedies of the '30s than a return to feel-good religious cinema). Here, God appears to a young girl (Louanne, who had earlier starred in a stage production of "Annie") and asks her to spread his Divine Word, causing her nothing but trouble from grown-ups in the process. Peculiar, family-oriented film appears to be warm-hearted enough, and Burns gets to chime in with a nice barrage of wry jibes, but the writing is half-slapstick and half-seriousness, with the adults of the piece considering putting little Louanne away, all of which makes God seem more like a troublemaker than an elderly friend. Louanne is another problem: a perky kid with wizened little eyes, she is untrained for screen-acting and occasionally seems awkward. The medium-budget production has a gloppy, TV-movie appearance, with few graceful touches. The final scene mimics the climax of the first "Oh, God!" in that it brings a wistful sentiment to the mix, which is welcomed. It's the most subtle moment in the movie. ** from ****
There's been a spate of recent surfing movies that I seem to haphazardly run across without advance warning. I caught this treasure on digital cable this week and what a pleasant surprise it was! The focus is on the pioneers of big wave surfing from the 60's Greg Noll to our current Laird Hamilton, from Waimea Bay to Mavericks to Jaws. Hell, I could watch a movie just about Laird Hamilton - one of this generation's great athletes - so the rest is just gravy. There's loads of good surfing mixed in with interviews of past and present surfing stars, in pleasant, relaxed and unpretentious fashion. Of all the surfing movies I've seen this tells the big-wave story the best, and I think it's my favorite. Enjoy!
Radiation pressure from the absorption and scattering of starlight by dust grains may be a crucial feedback mechanism in starburst galaxies and the self-gravitating parsec-scale disks that accompany the fueling of active galactic nuclei. I review the case for radiation pressure in both optically-thin and highly optically-thick contexts. I describe the conditions for which Eddington-limited star formation yields a characteristic flux of ~10^{13} L_sun/kpc^2, and I discuss the physical circumstances for which the flux from radiation pressure supported disks is below or above this value. In particular, I describe the young stellar disk on ~0.1 pc scales at the Galactic Center. I argue that its bolometric flux at formation, ~10^{15} L_sun/kpc^2, and the observed stellar mass and scale height imply that the disk may have been radiation pressure supported during formation.
It is an easy observation that every residuated lattice is in fact a semiring because multiplication distributes over join and the other axioms of a semiring are satisfied trivially. This semiring is commutative, idempotent and simple. The natural question arises if the converse assertion is also true. We show that the conversion is possible provided the given semiring is, moreover, completely distributive. We characterize semirings associated to complete residuated lattices satisfying the double negation law where the assumption of complete distributivity can be omitted. A similar result is obtained for idempotent residuated lattices.
Using the Kerr-Schild formalism to solve the Einstein-Maxwell equations, we study energy transport due to time-dependent electromagnetic perturbations around a Kerr black hole, which may work as a mechanism to illuminate a disk located on the equatorial plane. For such a disk-hole system it is found that the energy extraction from the hole can occur under the well-known superradiance condition for wave frequency, even though the energy absorption into the hole should be rather dominant near the polar region of the horizon. We estimate the efficiency of the superradiant amplification of the disk illumination. Further we calculate the time-averaged energy density distribution to show explicitly the existence of a negative energy region near the horizon and to discuss the possible generation of a hot spot on the disk.
To implement a blockchain, the trend is now to integrate a non-trivial Byzantine fault tolerant consensus algorithm instead of the seminal idea of waiting to receive blocks to decide upon the longest branch. After a decade of existence, blockchains trade now large amounts of valuable assets and a simple disagreement could lead to disastrous losses. Unfortunately, Byzantine consensus solutions used in blockchains are at best proved correct "by hand" as we are not aware of any of them having been formally verified. In this paper, we propose two contributions: (i) we illustrate the severity of the problem by listing six vulnerabilities of blockchain consensus including two new counter-examples; (ii) we then formally verify two Byzantine fault tolerant components of Red Belly Blockchain using the ByMC model checker. First, we specify a simple broadcast primitive in 116 lines of code that is verified in 40 seconds on a 2-core Intel machine. Then, we specify a blockchain consensus algorithm in 276 lines of code that is verified in 17 minutes on a 64-core AMD machine using MPI. To conclude, we argue that it has now become both relatively simple and crucial to formally verify the correctness of blockchain consensus protocols.
In the second section "Courant-Gelfand theorem" of his last published paper (Topological properties of eigenoscillations in mathematical physics, Proc. Steklov Institute Math. 273 (2011) 25--34), Arnold recounts Gelfand's strategy to prove that the zeros of any linear combination of the $n$ first eigenfunctions of the Sturm-Liouville problem $$-\, y"(s) + q(x)\, y(x) = \lambda\, y(x) \mbox{ in } ]0,1[\,, \mbox{ with } y(0)=y(1)=0\,,$$divide the interval into at most $n$ connected components, and concludes that "the lack of a published formal text with a rigorous proof \dots is still distressing." Inspired by Quantum mechanics, Gelfand's strategy consists in replacing the ana\-lysis of linear combinations of the $n$ first eigenfunctions by that of their Slater determinant which is the first eigenfunction of the associated $n$-particle operator acting on Fermions. In the present paper, we implement Gelfand's strategy, and give a complete proof of the above assertion. As a matter of fact, refining Gelfand's strategy, we prove a stronger property taking the multiplicity of zeros into account, a result which actually goes back to Sturm (1836).
On hot Jupiter exoplanets, strong horizontal and vertical winds should homogenize the abundances of the important absorbers CH$_4$ and CO much faster than chemical reactions restore chemical equilibrium. This effect, typically neglected in general circulation models (GCMs), has been suggested as explanation for discrepancies between observed infrared lightcurves and those predicted by GCMs: On the nightsides of several hot Jupiters, GCMs predict outgoing fluxes that are too large, especially in the Spitzer 4.5 $\mu$m band. We modified the SPARC/MITgcm to include disequilibrium abundances of CH$_4$, CO and H$_2$O by assuming that the CH$_4$/CO ratio is constant throughout the simulation domain. We ran simulations of hot Jupiter HD 189733b with 8 CH$_4$/CO ratios. In the more likely CO-dominated regime, we find temperature changes $\geq$50-100 K compared to the equilibrium chemistry case across large regions. This effect is large enough to affect predicted emission spectra and should thus be included in GCMs of hot Jupiters with equilibrium temperatures between 600K and 1300K. We find that spectra in regions with strong methane absorption, including the Spitzer 3.6 and 8 $\mu$m bands, are strongly impacted by disequilibrium abundances. We expect chemical quenching to result in much larger nightside fluxes in the 3.6 $\mu$m band, in stark contrast to observations. Meanwhile, we find almost no effect on predicted observations in the 4.5 $\mu$m band, as the opacity changes due to CO and H$_2$O offset each other. We thus conclude that disequilibrium carbon chemistry cannot explain the observed low nightside fluxes in the 4.5 $\mu$m band.
We present optical photometry and spectroscopy of SN2005ip for the first 3yr after discovery, showing an underlying Type II-L SN interacting with a steady wind to yield an unusual Type IIn spectrum. For the first 160d, it had a fast linear decline from a modest peak absolute magnitude of about -17.4 (unfiltered), followed by a plateau at roughly -14.8 for more than 2yr. Initially having a normal broad-lined spectrum superposed with sparse narrow lines from the photoionized CSM, it quickly developed signs of strong CSM interaction with a spectrum similar to that of SN1988Z. As the underlying SNII-L faded, SN2005ip exhibited a rich high-ionization spectrum with a dense forest of narrow coronal lines, unprecedented among SNe but reminiscent of some active galactic nuclei. The line-profile evolution of SN 2005ip confirms that dust formation caused its recently reported infrared excess, but these lines reveal that it is the first SN to show clear evidence for dust in both the fast SN ejecta and the slower post-shock gas. SN2005ip's complex spectrum confirms the origin of the strange blue continuum in SN2006jc, which also had post-shock dust formation. We suggest that SN2005ip's late-time plateau and coronal spectrum result from rejuvenated CSM interaction between a sustained fast shock and a clumpy stellar wind, where X-rays escape through the optically thin interclump regions to heat the pre-shock CSM to coronal temperatures.
The transition magnetic dipole and electric quadrupole moments of the radiative decays of the sextet heavy flavored spin 3/2 to the heavy spin 1/2 baryons are calculated within the light cone QCD sum rules approach. Using the obtained results, the decay rate for these transitions are also computed and compared with the existing predictions of the other approaches.
In the space of C^k piecewise expanding unimodal maps, k>=1, we characterize the C^1 smooth families of maps where the topological dynamics does not change (the "smooth deformations") as the families tangent to a continuous distribution of codimension-one subspaces (the "horizontal" directions) in that space. Furthermore such codimension-one subspaces are defined as the kernels of an explicit class of linear functionals. As a consequence we show the existence of C^{k-1+Lip} deformations tangent to every given C^k horizontal direction, for k>=2.
Finally! An Iranian film that is not made by Majidi, Kiarostami or the Makhmalbafs. This is a non-documentary, an entertaining black comedy with subversive young girls subtly kicking the 'system' in its ass. It's all about football and its funny, its really funny. The director says "The places are real, the event is real, and so are the characters and the extras. This is why I purposely chose not to use professional actors, as their presence would have introduced a notion of falseness." The non-actors will have you rooting for them straightaway unless a. your heart is made of stone b. you are blind. Excellently scripted, the film challenges patriarchal authority with an almost absurd freshness. It has won the Jury Grand Prize, Berlin, 2006. Dear reader, it's near-perfect. WHERE, where can I get hold of it?
What a piece of junk this movie was. The premise was okay, but even in the beginning with crappy effects to blend in a giant with normal sized people (even the effects in Hercules was better) I knew this would be bad. But the really awful part of the movie is the dialogs. It's completely incoherent, silly and stupid. I felt like it had been written by some 9th grader in creative class and gotten a D-. I want to slap Casper van Diem and the other actors for following this movie through.<br /><br />I've had my share of cheesy and bad movies (I love the tremors series), but this... I do not recommend it at all. It's silly and the totally flabbergastingly bad dialogs will make you cringe.
Okay like most Steven Seagal fans I know I not going expect a masterpiece every time he makes a film but I do expect the film to at least have some sorter budget. The main problem with the copy I watched was the terrible over dubbing I know that in some films this has to be done and I accept that but when they overdub with a totally different actors voice and keep doing this thru out the film it does take the magic of overdubbing away. Also the sets seem to be built with no care as in one scene the sliding glass top in a top secret lab has a massive crack going thru it. I was truly disappointed with this film and only hope Stevens next project will be more finished off before sending the film out for buying/renting. The story of this film had me wondering if I was watching a sci-fi film or not some parts seemed alien like but they never fully explained what was going on I found it very confusing.
Skipping right out of the package This seems like it would be a great workout but I cant use the warm up on phase 1 due to the disk skipping terribly not sure if it happens on any other selections or just this one but I'm pretty bummed about spending money and not being able to utilize the whole disk.
PKS 2155-304 is a blazar located in the Southern Hemisphere, monitored with the High Energy Stereoscopic System (H.E.S.S.) at very high energy (VHE, E>100 GeV) $\gamma$ rays every year since 2002. Thanks to the large data set collected in the VHE range and simultaneous coverage in optical, ultraviolet (UV), X-ray and high energy $\gamma$-ray ranges, this object is an excellent laboratory to study spectral and temporal variability in blazars. However, despite many years of dense monitoring, the nature of the variability observed in PKS 2155-304 remains puzzling. In this paper, we discuss the complex spectral and temporal variability observed in PKS 2155-304. The data discussed include VHE $\gamma$-ray data collected with H.E.S.S. between 2013 and 2016, complemented with multiwavelength (MWL) observations from Fermi-LAT, Swift-XRT, Swift-UVOT, SMARTS, and the ATOM telescope. During the period of monitoring, PKS 2155-304 was transitioning from its lower state to the flaring states, and exhibiting different flavors of outbursts. For the first time, orphan optical flare lasting a few months was observed. Correlation studies show an indication of correlation between the X-ray and VHE $\gamma$-ray fluxes. Interestingly, a comparison of optical and X-ray or VHE $\gamma$-ray fluxes does not show global correlation. However, two distinct tracks in the diagram were found, which correspond to the different flaring activity states of PKS 2155-304.
Swift J1753.5-0127 (J1753) is a candidate black hole low-mass X-ray binary (BH-LMXB) that was discovered in outburst in May 2005. It remained in outburst for $\sim12$ years, exhibiting a wide range of variability on various timescales, before entering quiescence after two short-lived, low-luminosity "mini-outbursts" in April 2017. The unusually long outburst duration in such a short-period ($P_{\rm orb}\approx3.24$ hrs) source, and complex variability observed during this outburst period, challenges the predictions of the widely accepted disc-instability model, which has been shown to broadly reproduce the behaviour of LMXB systems well. The long-term behaviour observed in J1753 is reminiscent of the Z Cam class of dwarf novae, whereby variable mass transfer from the companion star drives unusual outbursts, characterized by stalled decays and abrupt changes in luminosity. Using sophisticated modelling of the multi-wavelength light curves and spectra of J1753, during the $\sim12$ years the source was active, we investigate the hypothesis that periods of enhanced mass transfer from the companion star may have driven this unusually long outburst. Our modelling suggests that J1753 is in fact a BH-LMXB analogue to Z Cam systems, where the variable mass transfer from the companion star is driven by the changing irradiation properties of the system, affecting both the disc and companion star.
Awesome product! It’s cute and very functional my only ... Awesome product! It’s cute and very functional my only complaint is I wish the hook on top was larger because it doesn’t fit on my rods. This picture is my bathroom shower rod granted it’s a sturdy rod. It’s the closest one that fits
We use particle-in-cell (PIC) simulations and simple analytic models to investigate the laser-plasma interaction known as ponderomotive steepening. When normally incident laser light reflects at the critical surface of a plasma, the resulting standing electromagnetic wave modifies the electron density profile via the ponderomotive force, which creates peaks in the electron density separated by approximately half of the laser wavelength. What is less well studied is how this charge imbalance accelerates ions towards the electron density peaks, modifying the ion density profile of the plasma. Idealized PIC simulations with an extended underdense plasma shelf are used to isolate the dynamics of ion density peak growth for a 42 fs pulse from an 800 nm laser with an intensity of 10$^{18}$ W cm$^{-2}$. These simulations exhibit sustained longitudinal electric fields of 200 GV m$^{-1}$, which produce counter-steaming populations of ions reaching a few keV in energy. We compare these simulations to theoretical models, and we explore how ion energy depends on factors such as the plasma density and the laser wavelength, pulse duration, and intensity. We also provide relations for the strength of longitudinal electric fields and an approximate timescale for the density peaks to develop. These conclusions may be useful investigating the phenomenon of ponderomotive steepening as advances in laser technology allow shorter and more intense pulses to be produced at various wavelengths. We also discuss the parallels with other work studying the interference from two counter-propagating laser pulses.
The Spallation Neutron Source (SNS) is a pulsed source of neutrons and, as a byproduct of this operation, an intense source of neutrinos via stopped-pion decay. The COHERENT collaboration uses this source to investigate coherent elastic neutrino-nucleus scattering (CEvNS) with a suite of detectors. To enable precise cross-section measurements, we must address an estimated 10\% uncertainty in our flux calculation associated with the lack of data for $\pi^\pm$ production from 1 GeV protons on an Hg target. We present here our Geant4 simulation of neutrino production at the SNS and our plans to experimentally normalize this flux with the development of a 670 kg D$_2$O detector. Using the precise cross section calculations for neutrino interactions on deuterium, we will dramatically reduce our flux uncertainty.
Its not a bad product but its for beginners This is not a bad product, but definitely its not as good as the Fastlane from Endless Pool. When you compare the prices this one costs 20% or 30% of the Fastlane, so it much cheaper. Before buying it I tested the Fastlane and loved it, but it was very expensive, so I found this option here on amazon and bought it. My considerations are: - It does not generate enough water flow for an experienced swimmer. - Most of the times when I turn it on, it shows an error on the screen so I have to reset it. - The power transformer is big and has a short cord. I wish I could I could hide it in the engine room, but It was not possible because of the cord's length, so I wrote an email to the manufacturer but unfortunately the answer was that they do not sell a larger cable. If you are looking for an equipment to have fun and swim for a while, this is a good option. Nevertheless, if you want to train for a competition (in my case for triathlon) maybe this is not the most suitable option. Best. Rafael
The Skyrme model, an effective low energy theory rooted in large $N_c$ QCD, has been applied to the study of dense matter. Matter is described by various crystal structures of skyrmions. When this system is heated, the dominating thermal degrees of freedom are the fluctuating pions. Taking these mechanisms jointly produces a description of the chiral phase transition leading to the conventional phase diagram with critical temperatures and densities in agreement with expected values.
We consider the use of look-up tables (LUT) to simplify the hardware implementation of a deep learning network for inferencing after weights have been successfully trained. The use of LUT replaces the matrix multiply and add operations with a small number of LUTs and addition operations resulting in a completely multiplier-less implementation. We compare the different tradeoffs of this approach in terms of accuracy versus LUT size and the number of operations and show that similar performance can be obtained with a comparable memory footprint as a full precision deep neural network, but without the use of any multipliers. We illustrate this with several architectures such as MLP and CNN.
G_2 Yang--Mills theory is an interesting laboratory to investigate non-perturbative effects. On one hand, no conventional quark confinement via a linearly rising potential is present. On the other hand, its thermodynamic properties are similar to ordinary SU(N) Yang--Mills theory. Finally, it has been conjectured that gluons are removed from the physical spectrum in the same way as in SU(N) Yang--Mills theory. The last claim will be explored by determining the Landau-gauge ghost and gluon propagators, as well as the Faddeev--Popov operator eigenspectrum, in G_2 lattice gauge theory in two and three dimensions. The results are found to agree qualitatively with the SU(2) and SU(3) case. Therefore, the conjecture that Yang--Mills theories with different gauge groups are qualitatively similar on the level of their Landau gauge Green's functions is supported.
In this paper, we report the enhanced stability of induced synchronization by transient uncoupling observed in certain unidirectionally coupled second-order chaotic systems. The stability of synchronization observed in the coupled systems subjected to transient uncoupling is analyzed using the {\emph{Master Stability Function}}. The existence of the coupled systems in stable synchronized states over a certain range of the clipping fraction of the driven system is identified. The enhanced stable synchronized states are obtained for fixed values of clipping fraction in certain second-order chaotic systems. The two-parameter bifurcation diagram indicating the parameter regions over which stable synchronization occurs is presented. The negative eigenvalue regions of the driven system enabling induced synchronization is studied for all the systems. The enhancement of synchronization through transient uncoupling observed in coupled second-order non-autonomous chaotic systems is reported in the literature for the first time.
We have all been asking ourselves "why don't they remake the slasher films that were only OK instead of remaking the ones that were great already, that way they can only make it better?" well with Prom Night they have remade the average but trashy fun 80s Jamie Lee Curtis film and made it even WORSE. Its a paint by numbers slasher film which is clearly trying to attract the young teens (hence no violence etc), the knife in this slasher flick is blunt.The director spends so much time focusing on trying to make the rather attractive killer look somewhat creepy that anything else goes out of the window.The cast who include Britney Snow (who was superb in Hairspray) try their hardest but the material gives them nothing to do but pout and look scared.More annoying is how the death scenes are handled (we will hear the attack but wont see it). It also looks like the only place the knife in this film worked was in the editing suite since the film looks like it has been butchered (im guessing anything remotely scary ended up on the cutting room floor so as not to scare the kids) Yet in pours the money from Americans sending this film to number 1 at the box office!!! Slasher movies are a lot of fun but in Prom Nights case it made me want to download the original.I've seen scarier OC and Dawsons Creek episodes
A design tool was formulated for optimizing the efficiency of inorganic, thin-film, photovoltaic solar cells. The solar cell can have multiple semiconductor layers in addition to antireflection coatings, passivation layers, and buffer layers. The solar cell is backed by a metallic grating which is periodic along a fixed direction. The rigorous coupled-wave approach is used to calculate the electron-hole-pair generation rate. The hybridizable discontinuous Galerkin method is used to solve the drift-diffusion equations that govern charge-carrier transport in the semiconductor layers. The chief output is the solar-cell efficiency which is maximized using the differential evolution algorithm to determine the optimal dimensions and bandgaps of the semiconductor layers.
We present a non-perturbative expression for the scattering matrix of $N$ particles interacting inside a quantum dot. Characterizing the dot by its resonances, we find a compact form for the scattering matrix in a real-time representation. We study the transmission probabilities and interaction-induced orbital entanglement of two electrons incident on the dot in a spin-singlet state.
Read a bit about this. Michael Eisner was head of Disney when his company bought Weinstein's. A few years later, Disney fired the guy. Eisner's recall: Weinstein was an "unmitigated bully." We don't hear a lot about what might be called, "boardroom bashing," because to complain or protest is, well, unmanly.
Consider a random walk in random environment on a supercritical Galton--Watson tree, and let $\tau_n$ be the hitting time of generation $n$. The paper presents a large deviation principle for $\tau_n/n$, both in quenched and annealed cases. Then we investigate the subexponential situation, revealing a polynomial regime similar to the one encountered in one dimension. The paper heavily relies on estimates on the tail distribution of the first regeneration time.
There is no evidence that Mr. McGugan understands anything about the subject matter he expounds upon except for the 3rd hand garbage the Globe and Mail exchanges on their journalists network. There is no rational way to interpret the Canadian, British, and European central banks update on their respective economies inclusive of openness to raising their economic jurisdiction's interest rates as "a co-ordinated global effort." The effects of globalization lends itself to reducing the amount of independence between trading economies but hardly eliminating it. Modern monetary economic policy of economic jurisdictions subscribing to floating currency exchange rates works largely via the central bank purchasing and/or selling central bank short term notes (Treasure Bills, if you speak American,) and never "stocks, bonds, and real estate." bonds will be most directly effected by change in interest rate policy; the remainder indirectly as a currency's foreign exchange rates.

We have performed a detailed study of thermal annealing of the moment configuration in artificial spin ice. Permalloy (Ni$_{80}$Fe$_{20}$) artificial spin ice samples were examined in the prototypical square ice geometry, studying annealing as a function of island thickness, island shape, and annealing temperature and duration. We also measured the Curie temperature as a function of film thickness, finding that thickness has a strong effect on the Curie temperature in regimes of relevance to many studies of the dynamics of artificial spin ice systems. Increasing the interaction energy between island moments and reducing the energy barrier to flipping the island moments allows the system to more closely approach the collective low energy state of the moments upon annealing, suggesting new channels for understanding the thermalization processes in these important model systems.
MA: Go spout your communism in another country. If public sector unions quit using taxpayer dollars to support legislation and political candidates that do not represent the taxpayers, if unions quit forcing workers to join, if union leaders were not corrupt, if Democrats would quit advocating wealth redistribution, if unions quit forcing members to vote certain ways, etc, etc. Bullies, gangs, and violence are mostly a thing of the past and were tactics used by both sides. You should be proud of your union brothers and sisters, I am also. Unions, particularly in the private sector, are necessary and useful. In the public sector not so much. "Right to work" produces goods and services that union members utilize. As you can see there are two sides to this issue.
Gurinda Chada's semi-autobiographical film (2002) is a gentle, poignant comedy set in the ethnically diverse community near Heahthrow Airport in West London.<br /><br />Like the airliners which constantly arrive and depart from overhead, we follow the ups and downs of the two main characters Jess Bhamra (Parminder Nagra) and Jules Paxton (Keira Knightley) as they strike up an unlikely friendship which centres around their mutual passion for soccer and their technical infatuation with David Beckham.<br /><br />Much of the comedy grows out of the misunderstandings of the families of these two talented girls as they break all the expectations and conventions of their very different family backgrounds.<br /><br />Somewhere in the middle, as broker, peacemaker and blighted athlete, Joe (Jonathan Reece-Myers) - team coach for the Hounslow Harriers - intercedes in times of crisis, while at the same time remaining the main object of affection of both the main characters.<br /><br />Eventually, and not without many obstacles and triumphs on the way, we finally see our dedicated and beloved soccer heroines soaring away to realise their dreams.<br /><br />With great performances from Bollywood veteran Anupam Kher (Mr Bhamra), Shaheen Khan (Mrs Bhamra), Juliet Stevenson (Mrs Paxton) and Frank Harper (Mr Paxton) this really is a film that captures the urgent passion of adolescence and crosses all ethnic frontiers.<br /><br />Pinky Bamrha (Archie Panjabi) and (Taz) Trey Farley are struggling their own struggles, but nevertheless contribute greatly to our understanding of the main characters in the film.<br /><br />In it's own special way, this film tells an important story that in quite incidental the football. It celebrates the evolution in the understanding of ordinary people in ordinary families and the innate ability of the young to teach the old.
This assumption will also lead us to underpredict benefits since it is likely that increases in real U.S. income would also result in increased cost-of-illness (due, for example, to increases in wages paid to medical workers) and increased cost of work loss days (reflecting that if worker incomes are higher, the losses resulting from reduced worker production would also be higher).
Over the past decade, new data from HERMES, Jefferson Lab, Fermilab, and RHIC that connect to parton propagation and hadron formation have become available. Semi-inclusive DIS on nuclei, the Drell-Yan reaction, and heavy-ion collisions all bring different kinds of information on parton propagation within a medium, while the most direct information on hadron formation comes from the DIS data. Over the next decade one can hope to begin to understand these data within a unified picture. We briefly survey the most relevant data and the common elements of the physics picture, then highlight the new Jefferson Lab data, and close with a prospective for the future.
A previously found definition of complexity for spherically symmetric fluid distributions [1], is extended to axially symmetric static sources. In this case there are three different complexity factors, defined in terms of three structure scalars obtained from the orthogonal splitting of the Riemann tensor. All these three factors vanish, for what we consider the simplest fluid distribution, i.e a fluid spheroid with isotropic pressure and homogeneous energy density. However, as in the spherically symmetric case, they can also vanish for a variety of configurations, provided the energy density inhomogeneity terms cancel the pressure anisotropic ones in the expressions for the complexity factors. Some exact analytical solutions of this type are found and analyzed. At the light of the obtained results, some conclusions about the correlation (the lack of it) between symmetry and complexity, are put forward.
Sequels have a nasty habit of being disappointing, and the best credit I can give this is that it maintains that old tradition. These three tales aren't anything as good as any from the original Creepshow.<br /><br />By far the best of the trio involves a wooden idol which comes to life to take revenge on the thugs who killed its owners. The second story is about a lake monster which seems to be nothing more than a lot of floating slop, makes you wonder how anybody could possibly be scared of it. The third story includes a cameo from Stephen King as a truck driver, but other than that is a pretty unmemorable tale concerning the victim of a road traffic accident who comes back from the dead for the person who knocked him down.<br /><br />Watch the original Creepshow instead, or if you already have done then be happy with that.
We present long-term optical and RXTE data of two X-ray binary pulsars in the Small Magellanic Cloud, SXP46.6 and SXP6.85. The optical light curves of both sources show substantial (~0.5-0.8 mag) changes over the time span of the observations. While the optical data for SXP6.85 do not reveal any periodic behaviour, by detrending the optical measurements for SXP46.6 we find an orbital period of ~137 days, consistent with results from the X-ray data. The detection of Type I X-ray outbursts from SXP46.6, combined with the fact that we also see optical outbursts at these times, implies that SXP46.6 is a high orbital eccentricity system. Using contemporaneous optical spectra of SXP46.6 we find that the equivalent width of the H_alpha emission line changes over time indicating that the size of the circumstellar disc varies. By studying the history of the colour variations for SXP6.85 we find that the source gets redder as it brightens which can also be attributed to changes in the circumstellar disc. We do not find any correlation between the X-ray and optical data for SXP6.85. The results for SXP6.85 suggest that it is a low eccentricity binary and that the optical modulations are due to the Be phenomenon.

Seoul, Jan 14 (IANS) South Korean President Moon Jae-in said on Tuesday that it was premature to be pessimisic about the Korean peace process, pointing out the relatively good personal relationship between the leaders of North Korea and the US. In his New Year’s press conference at the presidential palace, he said: “I think we are not at the stage for now to be pessimistic about South-North dialogue and North Korea-US dialogue, although it’s not a stage be optimistic,” reports Yonhap News Agency. He mentioned US President Donald Trump’s birthday greetings to North Korean leader Kim Jong-un last week, which were sent in a personal letter, while concerns about Pyongyang’s provocations were running high. Moon called the letter, through which Trump emphasized his relationship with Kim once again, “very positive” and a “good idea”. “North Korea accepted it and immediately released a response. It stressed the relationship between the two leaders,” he said. Even if dialogue between Pyongyang and Washington was not active, Trump and Kim were maintaining mutual trust, with efforts for the resumption of talks under way, Moon said, adding that his government is continuing a push for expanding inter-Korean cooperation with an “optimistic prospect”. –IANS ksk/

In this paper we study the asymptotic behaviour of a nonlocal nonlinear parabolic equation governed by a parameter. After giving the existence of unique branch of solutions composed by stable solutions in stationary case, we gives for the parabolic problem $L^\infty $ estimates of solution based on using the Moser iterations and existence of global attractor. We finish our study by the issue of asymptotic behaviour in some cases when $t\to \infty$.
"Death Wish 3" is the movie equivalent of a shooting gallery. All the characters (apart from Bronson's Paul Kersey, of course) exist merely to be killed, either as "provocation" (the good guys) or as "retribution" (the villains). The director simply pours on the mindless violence (people even get burned alive and blown up), turning this into an urban version of "Commando" (and Charlie, like Arnold, rarely bothers to protect himself from the enemy gunfire). Fans of this short of thing (and, apparently, there are many) will enjoy it, others....beware. (*1/2)
The first two sequences of this movie set up the two conflicts: the -thematic- conflict between the soldier Todd and his suppressed humanity, and the -physical- conflict between Todd and his bio-engineered replacement. Both sequences are quite gripping in different ways.<br /><br />Peoples' screenplay falters somewhat by resolving the first of these arcs half-way through the movie, which means the second half is little more than a straightforward action romp.<br /><br />Nonetheless, kudos to the makers for creating an genre action piece with heart and even a bit of soul and especially to Kurt Russell who conveys much with very little.<br /><br />Not a great film, but one worth seeing.
Massively multi-label prediction/classification problems arise in environments like health-care or biology where very precise predictions are useful. One challenge with massively multi-label problems is that there is often a long-tailed frequency distribution for the labels, which results in few positive examples for the rare labels. We propose a solution to this problem by modifying the output layer of a neural network to create a Bayesian network of sigmoids which takes advantage of ontology relationships between the labels to help share information between the rare and the more common labels. We apply this method to the two massively multi-label tasks of disease prediction (ICD-9 codes) and protein function prediction (Gene Ontology terms) and obtain significant improvements in per-label AUROC and average precision for less common labels.
We propose a symmetric version of the multi-scale entanglement renormalization Ansatz (MERA) in two spatial dimensions (2D) and use this Ansatz to find an unknown ground state of a 2D quantum system. Results in the simple 2D quantum Ising model on the $8\times8$ square lattice are found to be very accurate even with the smallest non-trivial truncation parameter.
This paper describes an improved mapmaking approach with respect to the one used for the Planck High Frequency Instrument 2018 Legacy release. The algorithm SRoll2 better corrects the known instrumental effects that still affected mostly the polarized large-angular-scale data by distorting the signal, and/or leaving residuals observable in null tests. The main systematic effect is the nonlinear response of the onboard analog-to-digital convertors that was cleaned in the Planck HFI Legacy release as an empirical time-varying linear detector chain response which is the first-order effect. The SRoll2 method fits the model parameters for higher-order effects and corrects the full distortion of the signal. The model parameters are fitted using the redundancies in the data by iteratively comparing the data and a model. The polarization efficiency uncertainties and associated errors have also been corrected based on the redundancies in the data and their residual levels characterized with simulations. This paper demonstrates the effectiveness of the method using end-to-end simulations, and provides a measure of the systematic effect residuals that now fall well below the detector noise level. Finally, this paper describes and characterizes the resulting SRoll2 frequency maps using the associated simulations that are} released to the community at http://sroll20.ias.u-psud.fr.
I would put Death Wish 3 in the same box as Stallone's Cobra and Commando. The box that I would sell for $2 at a garage sale with all the videos inside. The story is about the main character coming back from the previous movies' success to ruin it all with this load of trash. Why did the makers want to destroy the reputation of the past 2 films with this cheap junk. The story is so lame that had to be a outrageous sequel. I mentioned Cobra earlier because it has the same mood, that one man can kill 20 or 30 gang members without a scratch. Both this movie and Cobra were bent on showing the hero firing his guns at hip level and the enemy falling in large numbers. Police officers spend hours at the shooting range so why did they get gunned down by gang members firing aimlessly from their hips? This movie was so bad I thought for a minute it was Death Wish 4.
Book listed as new, questionable. This book is awesome and a must have for any Kanye fan. Only problem is this is not a “new” item. Or if it is, the packaging and delivery method needs to be changed. I had to order two because the first one was delivered damaged and unfortunately the second one was too.
After recalling standard nonlinear port-Hamiltonian systems and their algebraic constraint equations, called here Dirac algebraic constraints, an extended class of port-Hamiltonian systems is introduced. This is based on replacing the Hamiltonian function by a general Lagrangian submanifold of the cotangent bundle of the state space manifold, motivated by developments in Barbero-Linan et al., and extending the linear theory as developed in Van der Schaft et al., Beattie et al.. The resulting new type of algebraic constraints equations are called Lagrange constraints. It is shown how Dirac algebraic constraints can be converted into Lagrange algebraic constraints by the introduction of extra state variables, and, conversely, how Lagrange algebraic constraints can be converted into Dirac algebraic constraints by the use of Morse families.
Let H be a complex Hilbert space of dimension no less than 2 and B(H) be the algebra of all bounded linear operators on H. We give the form of surjective maps on B(H) preserving c-numerical range of operator products when the maps satisfy preserving weak zero products. As a result, we obtain the characterization of surjective maps on Mn(C) preserving c-numerical range of operator products. The proof of the results depends on some propositions of operators in B(H), which are of different interest.
We study a finite spin-$\frac{1}{2}$ Ising chain with a spatially alternating transverse field of period 2. By means of a Jordan-Wigner transformation for even and odd sites, we are able to map it into a one-dimensional model of free fermions. We determine the ground-state energies in the positive- and negative-parity subspaces (subspaces with an even or odd total number of down spins, respectively) and compare them in order to establish the ground-state energy for the entire Hamiltonian. We derive closed-form expressions for this energy gap between the different parity subspaces and analyze its behavior and dependence on the system size in the various regimes of the applied field. Finally, we suggest an expression for the correlation length of such a model that is consistent with the various values found in the literature for its behavior in the vicinity of critical points.
Saw this movie in my English class this afternoon and was surprised by how bad this version was. Don't get me wrong, George C. Scott was terrific as Scrooge, but the rest of the cast fails so very badly. Sometimes I couldn't stop laughing at the stupid acting and the repeated line: "Merry Christmas to everyone!" Other times I almost fell asleep.<br /><br />The movie is based on a Charles Dickens short story about a rich guy, who don't think Christmas is nothing but humbug. After 30 minutes, the rich guy is visited by three ghosts, who persuade him to celebrate Christmas after all.<br /><br />I can not understand how this movie, with a script so bad it must have been written in five minutes, can be so well-rated. Instead of this piece of garbage, I recommend to you, the Bill Murray comedy Scrooged. That at least, was funny...
I recently got the chance to view "The Waterdance", and quite liked it. I don't really understand why its called that as there isn't really any dancing going on there, except maybe for the dancing at the strip club near the end. We are introduced to the main characters throughout the movie, invalids in a hospital. The story shows a love affair between a physically sisabled guy and a healthy woman, which is a very sweet story.Unfortunately, you don't get to see movies like that today. Im not "stuck in a time warp", im not saying that everything during the 80s and early 90s was better than today, but I really think the movie industry is deteriorating and there's much we can learn from old movies-by old movies i mean anything from 1920-1998.
you know and so um the thing is is that once you've done something wrong which is nationally you know internationally recognized then you're going to try to get out of it and the there's no way you know and especially since he's got inside Iraq for using you know chemical weapons and stuff
I had to get this movie, since it didn't come to where I live. I waited patiently and it was worth the wait. I totally fell in love with this movie. The chemistry between Walters and Grint you could see, since they also worked together on the Harry Potter movies.The woman who plays his overbearing, righteous mother really had me convinced all right and how much of a hypocrite she is, I think she did a great job playing the role. I only wish we could of had seen the actually sex scene or more of it. LOL, but of course we just have to use our imagination on how it went down. (snickers) I totally thought the movie was worth the wait and if you want a good movie to watch. Rent this movie. I do have to say that Rupert really did a great job and it's nice to see that he's doing movies outside of Harry Potter,even though I totally love him as Ron Weasley. The whole cast did a great job and I hope Rupert continues to act outside of Harry Potter to broaden his skill!
Atmospheric parameters determined via spectral modelling are unavailable for many of the known magnetic early B-type stars. We utilized high-resolution spectra together with NLTE models to measure effective temperatures $T_{\rm eff}$ and surface gravities $\log{g}$ of stars for which these measurements are not yet available. We find good agreement between our $T_{\rm eff}$ measurements and previous results obtained both photometrically and spectroscopically. For $\log{g}$, our results are compatible with previous spectroscopic measurements; however, surface gravities of stars previously determined photometrically have been substantially revised. We furthermore find that $\log{g}$ measurements obtained with HARPSpol are typically about 0.1 dex lower than those from comparable instruments. Luminosities were determined using Gaia Data Release 2 parallaxes. We find Gaia parallaxes to be unreliable for bright stars ($V<6$ mag) and for binaries; in these cases we reverted to Hipparcos parallaxes. In general we find luminosities systematically lower than those previously reported. Comparison of $\log{g}$ and $\log{L}$ to available rotational and magnetic measurements shows no correlation between either parameter with magnetic data, but a clear slow-down in rotation with both decreasing $\log{g}$ and increasing $\log{L}$, a result compatible with the expectation that magnetic braking should lead to rapid magnetic spindown that accelerates with increasing mass-loss.
Very good pen and great value! I actually ordered two of these pens, the beautiful blue and the traditional classy black. The nibs are smooth, the ink flow is nice and the converters are included - so many pens make you pay extra to get a converter for bottled inks, which I find a bit rude, and even moreso if you are paying for a premium pen. The shipping was prompt. Altogether, I would recommend these pens to anyone looking for a reasonably priced everyday fountain pen.
This paper revisits the physical meaning of linear, time-domain constitutive models with complex parameters that have been presented in the literature and concludes that such models are not physically realizable. While complex-parameter phenomenological models (including those with complex-order time derivatives) may be efficient in capturing in the frequency domain the frequency-dependent behavior of viscoelastic materials over a finite frequency band, they do not possess physically acceptable time-response functions. The paper first reviews the intimate relation between the causality of a physically realizable constitutive model and the analyticity of its frequency-response function and explains that in theory it is sufficient to conduct a nonlinear regression analysis for estimating the model parameters either on only the real part or on only the imaginary part of its frequency-response function, given that they are related with the Hilbert transform. Consequently, the resulting model-parameters are real-valued; therefore, there is no theoretical justification to conduct the nonlinear regression analysis for estimating the model parameters in the complex space. The paper concludes with an example by showing that the relaxation modulus of the complex-coefficient Maxwell model is a divergent function at all positive times; therefore it is not a physically realizable constitutive model.
the Mooch and I would have a really good time.....He would have been a challenge to be sure.....but it would have been fun....I'm retired, but if you see him, tell him there's still hope and I'm still available. I've tweeted the same offer to The Donald, but haven't heard back yet. Cheers, Gary Crum
"Unconscious bias explains why the higher echelons of government and business are still so pale and male. It explains why women are still so woefully shortchanged in STEM jobs (science, technology, engineering and mathematics). It explains why we need to move even more aggressively to recruit women and minorities... When Canadian STEM schools graduate a diverse blend of 50% females and males for 35 or 40 years then in 35 or 40 years take a snap shot of the workplace and I strongly suggest there will still remain statistical inequities between men and women but it won't be because the higher echelons are significantly pale and male...there will be many other cultural/religious/ethnic factors in play that already hold both men and women back. If as Margaret suggests we need to "more aggressively recruit women and minorities" and Canadian STEM schools aren't yet graduating a representative mix of the Canadian mosaic, will immigration policy support largely STEM female & minority hires?
uh-huh um i haven't really read anything like that in in in years there was a time when i was really into the home things and i did uh had my own garden and i did canning all those kind of things that was when i was about uh ten years younger
The presence of submicron grains has been inferred in several debris discs, despite the fact that these particles should be blown out by stellar radiation pressure on very short timescales. So far, no fully satisfying explanation has been found for this apparent paradox. We investigate the possibility that the observed abundances of submicron grains could be "naturally" produced in bright debris discs, where the high collisional activity produces them at a rate high enough to partially compensate for their rapid removal. We also investigate to what extent this potential presence of small grains can affect our understanding of some debris disc characteristics. We use a code following the collisional evolution of a debris disc down to submicron grains far below the limiting blow-out size $s_{blow}$. We explore different configurations: A and G stars, cold and warm discs, "bright" and "very bright" systems. We find that, in bright discs (fractional luminosity $>10^{-3}$) around A stars, there is always a high-enough amount of submicron grains to leave detectable signatures, both in scattered-light, where the disc's color becomes blue, and in the mid-IR ($10<\lambda<20\mu$m), where it boosts the disc's luminosity by at least a factor of 2 and induces a pronounced silicate solid-state band around $10\mu$m. We also show that, with this additional contribution of submicron grains, the SED can mimic that of two debris belts separated by a factor of 2 in radial distance. For G stars, the effect of $s<s_{blow}$ grains remains limited in the spectra, in spite of the fact that they dominate the system's geometrical cross section. We also find that, for all considered cases, the halo of small (bound and unbound) grains that extends far beyond the main disc contributes to $\sim50$% of the flux up to $\lambda\sim50\mu$m wavelengths.
We present a systematic and detailed study of the robustness of directed networks under random and targeted removal of links. We work with a set of network models of random and scale free type, generated with specific features of clustering and assortativity. Various strategies like random deletion of links, or deletions based on betweenness centrality and degrees of source and target nodes, are used to breakdown the networks. The robustness of the networks to the sustained loss of links is studied in terms of the sizes of the connected components and the inverse path lengths. The effects of clustering and 2-node degree correlations, on the robustness to attack, are also explored. We provide specific illustrations of our study on three real-world networks constructed from protein-protein interactions and from transport data.
The movie opens up with a long single shot of aisles in factory crammed with workers. My, what we've done to the planet you might think. I hope we get to see other things like this.<br /><br />That's very rare. When you're not looking at a horribly filmed angle of the narrator at a lecture hall, you're watching him set up his camera to take pictures in different locations. It'd be nice if chose areas that were more fitting with his topic but he doesn't. So, then you'll hear some more narration, watch a few pictures go by and watch him set up his camera. Why not use the filming camera to show more of the landscapes instead? It really kills any sense of pacing and paints the guy as more of vain jerk.<br /><br />I could read tips on how someone set up their camera, fast forward through this whole movie and waste a lot less time.
Account of an intrinsic spin-orbit coupling in the valence bands of common semiconductors yields the scalar spin-orbit-rotation term in the effective-mass Hamiltonian of the conduction-band electron. This result is obtained within the multiband envelope function approximation. Fundamentally, the spin-orbit-rotation coupling can be described in purely geometric terms as a consequence of the difference in the Berry phase acquired by the components of the spin-orbitally mixed Kramers-doublet during its cyclic evolution in the reciprocal momentum space.
Ok for the big stuff. So for some this might work perfectly. For us, this starfish looking thing worked but only for the larger stuff and even then it likes to collect on the edges instead of on the top, so some of the food particles do end up going down the drain. Update: we stopped using them because the bend would let to much though and they got stained. Im not entirely sure what they got stained with, but the picture shows the blue one and white one after about 2 months of use...which wasn't daily use to begin with. It does hold it place just fine, and it's not a complete wash, but we are already reverting back to using the normal circular metal inlay for the sink instead, and I'm not even risking using this to try and catch hair on the tub.
A method evaluating the sensitivity of a given parameter to topological changes is proposed within the method of moments paradigm. The basis functions are used as degrees of freedom which, when compared to the classical pixeling technique, provide important advantages, one of them being impedance matrix inversion free evaluation of the sensitivity. The devised procedure utilizes port modes and their superposition which, together with only a single evaluation of all matrix operators, leads to a computationally effective procedure. The proposed method is approximately one hundred times faster than contemporary approaches, which allows the investigation of the sensitivity and the modification of shapes in real-time. The method is compared with known approaches and its validity and effectiveness is verified using a series of examples. The procedure can be implemented in up-to-date EM simulators in a straightforward manner. It is shown that the iterative repetition of the topology sensitivity evaluation can be used for gradient-based topology synthesis. This technique can also be employed as a local step in global optimizers.
In this paper we consider nodes in network are heterogeneous and the link between nodes is caused by the potential dynamical demand of the nodes. Such demand can be measured by gravitation which increases with the heterogeneous strength of node and decreases with the geographical distance. Based on this, we propose a new model for spatial network from the view of gravitation. The model is to maximize the potential dynamical demand of the whole network, indicating the possible maximal efficiency of the network and the highest profits that operators may gain. The model can vary its topology by changing two parameters. A simulation for the Chinese city airline network is completed. In the end of this article we discuss the significance and advantage of the heterogeneous nodes.
The widely-adopted discretisation of the horizontal pressure gradient term formulated by Simmons and Burridge (1981) for atmospheric models on $\sigma$-$p$ hybrid vertical coordinate is found to incur spectral blocking for rotational wind components at high vertical levels when used in a spectral semi-Lagrangian model run on a linear grid. A remedy to this issue is proposed and tested using a spectral semi-implicit semi-Lagrangian hydrostatic primitive equations model. The proposed method removes aliasing errors at high wavenumbers by ensuring that the rotation-free property of the pressure gradient term on isobaric surface, a feature possessed by the continuous system, is preserved in the discretised system, which highlights the significance of mimetic discretisation within the context of numerical weather prediction models.
Let $G/K$ be a simply connected compact irreducible symmetric space of real rank one. For each $K$-type $\tau$ we compare the notions of $\tau$-representation equivalence with $\tau$-isospectrality. We exhibit infinitely many $K$-types $\tau$ so that, for arbitrary discrete subgroups $\Gamma$ and $\Gamma'$ of $G$, if the multiplicities of $\lambda$ in the spectra of the Laplace operators acting on sections of the induced $\tau$-vector bundles over $\Gamma\backslash G/K$ and $\Gamma'\backslash G/K$ agree for all but finitely many $\lambda$, then $\Gamma$ and $\Gamma'$ are $\tau$-representation equivalent in $G$ (i.e.\ $\dim \operatorname{Hom}_G(V_\pi, L^2(\Gamma\backslash G))=\dim \operatorname{Hom}_G(V_\pi, L^2(\Gamma'\backslash G))$ for all $\pi\in \widehat G$ satisfying $\operatorname{Hom}_K(V_\tau,V_\pi)\neq0$). In particular $\Gamma\backslash G/K$ and $\Gamma'\backslash G/K$ are $\tau$-isospectral (i.e.\ the multiplicities agree for all $\lambda$). We specially study the case of $p$-form representations, i.e. the irreducible subrepresentations $\tau$ of the representation $\tau_p$ of $K$ on the $p$-exterior power of the complexified cotangent bundle $\bigwedge^p T_{\mathbb C}^*M$. We show that for such $\tau$, in most cases $\tau$-isospectrality implies $\tau$-representation equivalence. We construct an explicit counter-example for $G/K= \operatorname{SO}(4n)/ \operatorname{SO}(4n-1)\simeq S^{4n-1}$.
Here are the facts foreign buyers get an automatic 25% discount off the price of a home due to exchange. Vancouver is the second least affordable city in the world primarily due to house prices and although a buyer's tax was put in place and sales have slowed but prices are still up. Vancouver's problem is no land, a problem the Toronto region does not have. Will a 15% tax help in TO, no as we are only on sale at a 10% off. The first step is stopping the option flippers that are selling a contract without buying the house. Require all accepted offers to be registered on title including assignments of options with the realtor being required to get a clearance certificate from Canada Revenue for each transaction. Increase the capital gains tax on options profits to 80%. As for the foreign buyer that actually purchases a home add a non-occupancy tax if the home is unoccupied for any period over 30 days and require the realtor to register the property with the city as foreign owned.
