description: Using the model of Nambu and Jona-Lasinio to provide a microscopic description of both the structure of the nucleon and of the quark to hadron elementary fragmentation functions, we investigate the transverse momentum dependence of the unpolarized quark distributions in the nucleon and of the quark to pion and kaon fragmentation functions. The transverse momentum dependence of the fragmentation functions is determined within a Monte Carlo framework, with the notable result that the average $P_\perp^2$ of the produced kaons is significantly larger than that of the pions. We also find that $$ has a sizable $z$ dependence, in contrast with the naive Gaussian ansatz for the fragmentation functions. Diquark correlations in the nucleon give rise to a non-trivial flavor dependence in the unpolarized transverse momentum dependent quark distribution functions. The $$ of the quarks in the nucleon are also found to have a sizable $x$ dependence. Finally, these results are used as input to a Monte Carlo event generator for semi-inclusive deep inelastic scattering (SIDIS), which is used to determine the average transverse momentum squared of the produced hadrons measured in SIDIS, namely $$. Again we find that the average $P_T^2$ of the produced kaons in SIDIS is significantly larger than that of the pions and in each case $\la P_T^2 \ra$ has a sizable $z$ dependence.

description: Fundamental frequency contours for speech, as obtained by common pitch tracking algorithms, contain a great deal of fine detail that is unlikely to hold much perceptual significance for listeners. In our experiments, a radically reduced pitch contour consisting of a single linear segment for each syllable was found to judged as equally natural as the original pitch track by listeners, based on high-quality analysis-synthesis. We describe the algorithms both for segmenting speech into syllables based on fitting Gaussians to the energy envelope, and for approximating the pitch contour by independent linear segments for each syllable. We report our web-based test in which 40 listeners compared the stylized pitch contour resyntheses to equivalent resyntheses based on the original pitch track, and also to pitch tracks stylized by the existing Momel algorithm. Listeners preferred the original pitch contour to the linear approximation in only 60% of cases, where 50% would indicate random guessing. By contrast, the original was preferred over Momel in 74% of cases.

description: The time series of normalized difference vegetation index (NDVI) and interferometric coherence extracted from optical and Synthetic Aperture Radar (SAR) images, respectively, have strong responses to sudden landslide failures in vegetated regions, which is expressed by a sudden increase or decrease in the values of NDVI and coherence. Compared with optical sensors, SAR sensors are not affected by cloud and daylight conditions and can detect the occurrence time of failure in near real-time. The purpose of this paper is to automatically determine the time of failure occurrence using time series coherence values. We propose, based on some existing anomaly detection algorithms, a deep neural network-based anomaly detection strategy that combines supervised and unsupervised learning without a priori knowledge about failure time. Our experiment using July 21, 2020 Shaziba landslide in China shows that in comparison to widely used unsupervised methodology, the use of our algorithm leads to a more accurate detection of the timing of the landslide failure.

description: Republicans and other right wingers are not troubled by class warfare in the abstract, otherwise they would have said something during the last three decades when the political and financial leadership of the U.S., with the close support of the Republican, and too frequently, Democratic parties, have waged class warfare on the poor on behalf of the wealthy. Deregulation, cutting social programs and increasingly regressive tax structures have all been part of an effort to shift wealth from the poor and middle class to the wealthy. This kind of class warfare has been met with no concern at all from the right. When Republicans get upset about class warfare, what they are really angry about is that poor and working people are fighting back. That may be beginning now on Wall Street and elsewhere.

description: Data management systems have traditionally been designed to support either long-running analytics queries or short-lived transactions, but an increasing number of applications need both. For example, online games, socio-mobile apps, and e-commerce sites need to not only maintain operational state, but also analyze that data quickly to make predictions and recommendations that improve user experience. In this paper, we present Minuet, a distributed, main-memory B-tree that supports both transactions and copy-on-write snapshots for in-situ analytics. Minuet uses main-memory storage to enable low-latency transactional operations as well as analytics queries without compromising transaction performance. In addition to supporting read-only analytics queries on snapshots, Minuet supports writable clones, so that users can create branching versions of the data. This feature can be quite useful, e.g. to support complex "what-if" analysis or to facilitate wide-area replication. Our experiments show that Minuet outperforms a commercial main-memory database in many ways. It scales to hundreds of cores and TBs of memory, and can process hundreds of thousands of B-tree operations per second while executing long-running scans.

description: Romney is, by the standards of most of the post-war period, a very ordinary candidate for his party's nomination. His relative lack of experience on foreign policy and singularly uninspiring style are clear weaknesses. However, he looks presidential, can speak fluently on most major issues, works hard and presents himself as bright and mature. He will be a strong opponent for President Obama, but his path to the nomination has been a strange one revealing the hollowness of today's Republican Party.

description: The determination of quark angular momentum requires the knowledge of the generalized parton distribution E in the forward limit. We assume a connection between this function and the Sivers transverse-momentum distribution, based on model calculations and theoretical considerations. Using this assumption, we show that it is possible to fit at the same time nucleon magnetic moments and semi-inclusive single-spin asymmetries. This imposes additional constraints on the Sivers function and opens a plausible way to quantifying quark angular momentum.

Surface codes, the 2D classical Ising model, and non-interacting fermions
Creators: name: Goff, Leonard Thomas
Publisher: name: University of British Columbia
Year: 2011

description: In this thesis, we consider the task of simulating measurement-based quantum computation (MBQC) on surface code states: the generalization of Kitaev's toric code to graphs embedded on a surface of higher genus. We define a family of higher genus graphs and a simple ordering of single qubit measurements, and find that simulating MBQC on any of the associated surface code states is equivalent to evaluating the inner-product between a product state and a surface code state on another graph. We further find that such an inner-product can always be written as a sum of one or more 2D classical Ising model partition functions, with appropriate couplings. For certain higher genus square lattices, we develop a means to evaluate this partition function in a number of steps that scales polynomially in the number of qubits, but exponentially in the genus of the embedded graph. The method makes use of the transfer matrix formalism for the Ising partition function, and a subsequent mapping to fermion operators. We synthesize these results to relate the simulation of MBQC on certain surface code states to a system of fermions interacting with the encoded qubits of the surface code. We identify a family of states in the code space of the surface code on our higher genus graphs for which MBQC can be simulated efficiently in all parameters, including the genus of the embedded graph. Finally, we identify two connections between the complexity of this task and entanglement.
Interplay between chiral and axial symmetries in a SU(2) Nambu--Jona-Lasinio Model with the Polyakov loop

description: We consider a two flavor Polyakov--Nambu--Jona-Lasinio (PNJL) model where the Lagrangian includes an interaction term that explicitly breaks the U$_A(1)$ anomaly. At finite temperature, the restoration of chiral and axial symmetries, signaled by the behavior of several observables, is investigated. We compare the effects of two regularizations at finite temperature, one of them, that allows high momentum quarks states, leading to the full recovery of chiral symmetry. From the analysis of the behavior of the topological susceptibility and of the mesonic masses of the axial partners, it is found in the SU(2) model that, unlike the SU(3) results, the recovery of the axial symmetry is not a consequence of the full recovery of the chiral symmetry. Thus, one needs to use an additional idea, by means of a temperature dependence of the anomaly coefficient, that simulates instanton suppression effects.

description: Traffic regulators at intersections act as an essential factor that influences traffic flow and, subsequently, the route choices of commuters. A digital map that provides up-to-date traffic control information is beneficial not only for facilitating the commuters’ trips, but also for energy-saving and environmental protection. In this paper, instead of using expensive surveying methods, we propose an automatic way based on a Conditional Variational Autoencoder (CVAE) to recognize traffic regulators, i. e., arm rules at intersections, by leveraging the GPS data collected from vehicles and the satellite imagery retrieved from digital maps, i. e., Google Maps. We apply a Long Short-Term Memory to extract the motion dynamics over a GPS sequence traversed through the intersection. Simultaneously, we build a Convolutional Neural Network (CNN) to extract the grid-based local imagery information associated with each step of the GPS positions. Moreover, a self-attention mechanism is adopted to extract the spatial and temporal features over both the GPS and grid sequences. The extracted temporal and spatial features are then combined for detecting the traffic arm rules. To analyze the performance of our method, we tested it on a GPS dataset collected by driving vehicles in Hannover, a medium-sized German city. Compared to a Random Forest model and an Encoder-Decoder model, our proposed model achieved better results with both accuracy and F1-score of 0.90 for the three-class (arm rules of uncontrolled, traffic light, and priority sign) task. We also carried out ablation studies to further investigate the effectiveness of the GPS input branch, the image input branch, and the self-attention mechanism in our model.

Hurricane Katrina (2005)

description: This article talks about the programs that were developed post-Katrina in accordance with the mental health facilities and care programs.
The Children’s Health Fund was funded 20 years ago to provide medical services to underserved children and families through mobile units. We have found mobile units to be effective ways of delivering services to people in need post-trauma or post-disaster as well as for primary care. The mental health component had not been a part of it, and I will tell you about how we began that post-9/11. As far as a public health agenda, we also felt that there was a need to make sure that the work we do is informed by research, by an understanding of what happens post-trauma, and also by a desire to understand more how can we do this in a better way next time. So research and evaluation have always been an important component of what we do.
We currently have three programs in the Gulf Coast, one in Mississippi and two in Louisiana. They are comprised of a mental health unit and a medical unit. The units are big blue vans that go to places where we have identified need, and they park in sites of need, and medical and mental health professionals provide services. We use electronic records, so that is one way in which we are able to serve people who might need to move or who do not know exactly where they will be. Our goal is to serve as a “medical home.”

description: We study the dynamics of two types of pairs of excitations which are bound despite their strong repulsive interaction. One corresponds to doubly occupied sites in one-dimensional Bose-Hubbard systems, the so-called doublons. The other is pairs of neighboring excited spins in anisotropic Heisenberg spin-1/2 chains. We investigate the possibility of decay of the bound pairs due to resonant scattering by a defect or due to collisions of the pairs. We find that the amplitudes of the corresponding transitions are very small. This is a result of destructive quantum interference and explains the stability of the bound pairs.

description: Der Übergang von der Trächtigkeit zur Frühlaktation (Transitzeit) stellt aufgrund einer sprunghaften Steigerung des Energiebedarfs eine hohe metabolische Belastung für die Milchkuh dar, wodurch inflammatorische Prozesse im tierischen Stoffwechsel aktiviert werden. Dies ist verbunden mit einer Induktion von Stress im endoplasmatischen Retikulum (ER) in der Leber von hochleistenden Milchkühen, welcher zur Entwicklung des Fettlebersyndroms und zur Ketose führen kann. Durch Hinzugabe eines polyphenolreichen Pflanzenextrakts (Traubentrester, Pflanzenprodukt aus Grüntee und Curcuma) kann sowohl die Inflammation, als auch der ER Stress in der Leber von Hochleistungskühen in der Frühlaktation verringert werden, was zur Verbesserung der Tiergesundheit und somit zu einer verbesserten Milchleistung führt.
description: The transition period, spanning the period of 3 weeks pre-partum to 3 weeks post-partum, is widely recognised as the most metabolically challenging time in the production cycle of high-yielding dairy cows due to metabolic and inflammatory stimuli, which are associated with the development of stress of the endoplasmic reticulum (ER) in the liver, which contributes to the development of liver-associated diseases. Supplementing a plant extract rich in flavonoids (grape seed and grape marc meal extract (GSGME), plant product consisting of green tea and curcuma extract) attenuates inflammation and ER stress in the liver of dairy cows in early lactation which leads to an enhancement of animal health associated with a significantly improved milk yield.

description: Planning realizable and stable grasps on 3D objects is crucial for many robotics applications, but grasp planners often ignore the relative sizes of the robotic hand and the object being grasped or do not account for physical joint and positioning limitations. We present a grasp planner that can consider the full range of parameters of a real hand and an arbitrary object, including physical and material properties as well as environmental obstacles and forces, and produce an output grasp that can be immediately executed. We do this by decomposing a 3D model into a superquadric 'decomposition tree' which we use to prune the intractably large space of possible grasps into a subspace that is likely to contain many good grasps. This subspace can be sampled and evaluated in GraspIt!, our 3D grasping simulator, to find a set of highly stable grasps, all of which are physically realizable. We show grasp results on various models using a Barrett hand.

description: General relativistic corrections to the galaxy power spectrum appearing at the horizon scale, if neglected, may induce biases on the measured values of the cosmological parameters. In this paper, we study the impact of general relativistic effects on non standard cosmologies such as scenarios with a time dependent dark energy equation of state, with a coupling between the dark energy and the dark matter fluids or with non-Gaussianities. We then explore whether general relativistic corrections affect future constraints on cosmological parameters in the case of a constant dark energy equation of state and of non-Gaussianities. We find that relativistic corrections on the power spectrum are not expected to affect the foreseen errors on the cosmological parameters nor to induce large biases on them.

description: Existing cover song detection systems require prior knowledge of the number of cover songs in a test set in order to identify cover(s) to a reference song. We describe a system that does not require such prior knowledge. The input to the system is a reference track and test track, and the output is a binary classification of whether the inputs are either a reference and a cover or a reference and a non-cover. The system differs from state-of-the-art detectors by calculating multiple input features, performing a novel type of test song normalization in order to combat against "impostor" tracks, and performing classification using either a support vector machine (SVM) or multi-layer perceptron (MLP). On the covers80 test set, the system achieves an equal error rate of 10%, compared to 21.3% achieved by the 2007 LabROSA cover song detection system.

description: The human hand is unrivaled in its ability to grasp and manipulate objects, but we still do not understand all of its complexities. One benefit it has over traditional robot hands is the fact that our fingers conform to a grasped object's shape, giving rise to larger contact areas and the ability to apply larger frictional forces. In this paper, we demonstrate how we have extended our simulation and analysis system with finite element modeling to allow us to evaluate these complex contact types. We also propose a new contact model that better accounts for the deformations and show how grasp quality is affected. This work is part of a larger project to understand the benefits the human hand has in grasping.

description: The formal deformation space of a supersingular Barsotti-Tate group over of dimension two equipped with an action of Z_{p^2} is known to be isomorphic to the formal spectrum of a power series ring in two variables. If one chooses an extra Z_{p^2}-linear endomorphism of the p-divisible group then the locus in the formal deformation space formed by those deformations for which the extra endomorphism lifts is a closed formal subscheme of codimension two. We give a complete description of the irreducible components of this formal subscheme, compute the multiplicities of these components, and compute the intersection numbers of the components with a distinguished closed formal subscheme of codimension one. These calculations, which extend the Gross-Keating theory of quasi-canonical lifts, are used in the companion article "Intersection theory on Shimura surfaces II" to compute global intersection numbers of special cycles on the integral model of a Shimura surface.

description: This paper considers the extreme type-II Ginzburg--Landau equations, a nonlinear PDE model for describing the states of a wide range of superconductors. Based on properties of the Jacobian operator and an AMG strategy, a preconditioned Newton--Krylov method is constructed. After a finite-volume-type discretization, numerical experiments are done for representative two- and three-dimensional domains. Strong numerical evidence is provided that the number of Krylov iterations is independent of the dimension $n$ of the solution space, yielding an overall solver complexity of O(n).

A Perry or Bachmann Nomination May Not Be Good for Democrats
Creators: name: Mitchell, Lincoln A.
Publisher: name: Columbia University
Year: 2011
Subjects: subject: Political science
subject: FOS: Political science

description: Perry and Bachmann have a great deal in common and, accordingly, can both be easily portrayed as dangerous, and probably slightly nutty, extremists in a general election. For this reason, many Democrats are hopeful that one of these two will be the eventual Republican nominee, rather than Romney who is more moderate and would probably be a stronger candidate against President Obama in the general election.
Democrats should be wary of this kind of thinking for several reasons.

Do storytelling podcasts build social capital? An exploration of Krista Tippett’s On Being Project podcasts
Creators: name: Anderson, Sonja
Publisher: name: CQUniversity
Year: 2023
Subjects: Communication and media studies not elsewhere classified

description: Podcasts are the digital form of the traditional practice of oral storytelling, the customary method for human beings to share experience through the societal ritual of translating individual and collective understandings into narrative form. Stories transfer knowledge and insight, an important practice for social cohesion and human survival. In the current technologically-driven environment, podcasters (those who create and distribute podcasts) have become the oracles of the digital epoch, delivering stories and informing through globally accessible networks. The aims of this study include the exploration of a specific type of podcast and whether they work to create social solidarity (social capital) in members of a listening audience. The digital platform, On Being Project, states that the intention of its podcasts is to offer opportunity to listeners to be informed by the stories told, of new pathways for living and surviving. The research explores whether listeners respond to the site’s encouragement to interact through discussion and sharing individual ideas on the podcasted content, to create a better understanding of current cultural challenges framed by new ideas heard, and the commonality of human beings: in other words, the elements of Putnam’s theory of social capital. The research used an audience member survey to collate responses to the listening experience and the analysis of the ideas expressed in answers. Evaluation of results demonstrated that audience members were responsive to innovative approaches to alternative cultural ideologies and a willingness for reciprocal social interaction. The results are presented as a foundation for further research into the effectiveness of podcasts as a tool for social network building.
Determination of the refractive index of the Black Sheet for the T2K experiment
Creators: name: Sabouri, Shirin
Publisher: name: University of British Columbia
Year: 2011

description: “Black Sheet” is a thin layer of polyethylene terephthalate mixed with carbon. It is used as a light absorber surface in the inner structure of the Super-Kamiokande (SK) detector for the T2K experiment. To make a full event reconstruction in the SK detector, knowing the optical properties of the Black Sheet is required. Specifically, it is very important to know the complex refractive index as a function of the wave length of the incident light. In this thesis, the experimental results leading to the calculation of the refractive index of the Black Sheet for three different wave lengths are provided. The accuracy of the experiments is validated by testing two control samples. The results show that the real and imaginary parts of the refractive index of the control samples can be determined with tolerances of about 0.02 and 0.1 with 90% confidence level, respectively.
Bridging the gap by shaking superfluid matter

description: In cold compact stars, Cooper pairing between fermions in dense matter leads to the formation of a gap in their excitation spectrum and typically exponentially suppresses transport properties. However, we show here that weak Urca reactions become strongly enhanced and approach their ungapped level when the star undergoes density oscillations of sufficiently large amplitude. We study both the neutrino emissivity and the bulk viscosity due to direct Urca processes in hadronic, hyperonic and quark matter and discuss different superfluid and superconducting pairing patterns.

description: The influence of repeated projective measurements on the dynamics of the state of a quantum system is studied in dependence of the time lag $τ$ between successive measurements. In the limit of infinitely many measurements of the occupancy of a single state the total system approaches a uniform state. The asymptotic approach to this state is exponential in the case of finite Hilbert space dimension. The rate characterizing this approach undergoes a sharp transition from a monotonically increasing to an erratically varying function of the time between subsequent measurements.
A Classification Approach to Melody Transcription

description: Melodies provide an important conceptual summarization of polyphonic audio. The extraction of melodic content has practical applications ranging from content-based audio retrieval to the analysis of musical structure. In contrast to previous transcription systems based on a model of the harmonic (or periodic) structure of musical pitches, we present a classification-based system for performing automatic melody transcription that makes no assumptions beyond what is learned from its training data. We evaluate the success of our algorithm by predicting the melody of the ISMIR 2004 Melody Competition evaluation set and on newly-generated test data. We show that a Support Vector Machine melodic classifier produces results comparable to state of the art model-based transcription systems.
