description: A theory of integer quantum Hall effect(QHE) in realistic systems based on von Neumann lattice is presented. We show that the momentum representation is quite useful and that the quantum Hall regime(QHR), which is defined by the propagator in the momentum representation, is realized. In QHR, the Hall conductance is given by a topological invariant of the momentum space and is quantized exactly. The edge states do not modify the value and topological property of $σ_{xy}$ in QHR. We next compute distribution of current based on effective action and find a finite amount of current in the bulk and the edge, generally. Due to the Hall electric field in the bulk, breakdown of the QHE occurs. The critical electric field of the breakdown is proportional to $B^{3/2}$ and the proportional constant has no dependence on Landau levels in our theory, in agreement with the recent experiments.

description: Data on kaon and $Φ$ production in nuclear collisions as a function of centrality are analysed both at AGS and SPS energy range. We compare the results of several experiments, looking for common trend in `participant scaling' of production yields. We find a smooth description of scaled kaon and $Φ$ yields as a function of participant density. We also show a participant density dependence of kaons and $Φ$ produced in the forward hemisphere for proton-nucleus collisions.

description: Exclusive nonleptonic bottom meson decays are studied in the covariant osillator quark model using the factorization assumption. The main feature of this model is that it can simultaniously be applied to both heavy to heavy and heavy to light transitions, satisfying the constraints of the heavy quark effective theory (HQET) in the appropriate limit. The results obtained are in overall agreement with the present experimental data for various B decays.

Evidence for Charge Symmetry Violation in Parton Distributions

description: By comparing structure functions measured in neutrino and charged lepton deep inelastic scattering, one can test the validity of parton charge symmetry. New experiments allow us to make such tests, which set rather tight upper limits on parton charge symmetry violation [CSV] for intermediate Bjorken $x$, but which appear to show sizable CSV effects at small $x$. We show that neither nuclear shadowing nor contributions from strange and antistrange quark distributions can account for the experimentally observed difference between the two structure functions. We are therefore forced to consider the possibility of a large CSV effect in the nucleon sea quark distributions. We discuss the consequences of this effect for other observables, and we propose an experiment which could detect a large CSV component in the nucleon sea.

description: The development and identification of effective optimization algorithms for non-convex real-world problems is a challenge in global optimization. Because theoretical performance analysis is difficult, and problems based on models of real-world systems are often computationally expensive, several artificial performance test problems and test function generators have been proposed for empirical comparative assessment and analysis of metaheuristic optimization algorithms. These test problems however often lack the complex function structures and forthcoming difficulties that can appear in real-world problems. This communication presents a method to systematically build test problems with various types and degrees of difficulty. By weighted composition of parameterized random fields, challenging test functions with tunable function features such as, variance contribution distribution, interaction order, and nonlinearity can be constructed. The method is described, and its applicability to optimization performance analysis is described by means of a few basic examples. The method aims to set a step forward in the systematic generation of global optimization test problems, which could lead to a better understanding of the performance of optimization algorithms on problem types with particular characteristics. On request an introductive MATLAB implementation of a test function generator based on the presented method is available.

description: This thesis examines the "freak show" in American history and analyzes how shifts in medical knowledge and the public's perception of that knowledge changed attitudes about people's physical and mental abnormalities. Through a study of popular culture, medical discourse, and the freak show itself, it is possible to uncover how freakishness came to be medicalized and treated as a medical problem. In doing so, it explores the often-racialized view of freaks as well as the birth of notions of disability in the American context. As medical science progressed and revealed the causes behind human abnormalities, curiosity transformed into disability. Resulting in a change in how audiences regarded the freak shows that were once extremely popular.

description: Making kirigami-inspired cuts into a sheet has been shown to be an effective way of designing stretchable materials with metamorphic properties where the 2D shape can transform into complex 3D shapes. However, finding the optimal solutions is not straightforward as the number of possible cutting patterns grows exponentially with system size. Here, we report on how machine learning (ML) can be used to approximate the target properties, such as yield stress and yield strain, as a function of cutting pattern. Our approach enables the rapid discovery of kirigami designs that yield extreme stretchability as verified by molecular dynamics (MD) simulations. We find that convolutional neural networks (CNN), commonly used for classification in vision tasks, can be applied for regression to achieve an accuracy close to the precision of the MD simulations. This approach can then be used to search for optimal designs that maximize elastic stretchability with only 1000 training samples in a large design space of $\sim 4\times10^6$ candidate designs. This example demonstrates the power and potential of ML in finding optimal kirigami designs at a fraction of iterations that would be required of a purely MD or experiment-based approach, where no prior knowledge of the governing physics is known or available.

description: Cabibbo allowed two-body hadronic weak decays of Lambda b baryons are analyzed in the factorization approximation. We use the covariant oscillator quark model to evaluate the heavy to heavy and heavy to light form factors. When applied in the heavy quark limit, our form factors satisfy all the constraints imposed by heavy quark symmetry. The decay rates and up-down asymmetries for Lambda b baryon decaying into Lambda c +P(V) are calculated. It is found that the up-down asymmetry is negative in all these decay modes. Furthermore, the prediction Br(Lambda b to Lambda+J/psi)=2.49 times 10^-4 is consistent with the recent experimental data. Finally it is pointed out that the CKM-Wolfenstein parameter rho^2+eta^2, where eta is the CP phase, can be determined from the ratio of the widths Lambda b to Lambda bar D^0 and Lambda b to Lambda J/psi, independent of the QCD parameter. The value of (rho^2 +eta^2)^1/2 calculated in our model agrees very well with the value recently predicted by Rosner.

title: Applications of Secure Computation to Set Intersection
Creators: name: (:Unkn) Unknown
Publisher: name: George Mason University
Year: 2021

description: Secure multi-party computation protocols allow many parties to compute a function over their private data without revealing their data to other parties. We look at a concrete example of secure multi-party computation in real world applications: private set intersection (PSI). We design more efficient private set intersection protocols with different flavors: two-party PSI with an untrusted third party, two-party asymmetric PSI via vector OLE, and PSI via MPC-in-the-head. Our PSI protocols are designed to meet different needs. The PSI via MPC-in-the-head protocols allow two or more parties to compute the intersection between their input sets, and the output is learned by all the parties. The other two focus on the two-party setting with a clear use case for each. The PSI via vector OLE protocols focus on the problem of mobile contact discovery. They are executed in two-party setting between a server that has a large input set (billions of items) and a client with much smaller input set (a few thousand items). The two-party PSI with an untrusted third party protocols allow the two parties, which provide input, to securely compute an arbitrary function over the intersection.

Interplay of spectral components in timing properties of accreting compact objects
Creators: name: Veledina, Alexandra
Publisher: name: arXiv
Year: 2018
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: X-ray variability of accreting black hole binaries is believed to be produced by the fluctuations propagating towards the compact object. Observations suggest the light curves in different energy bands are connected, but the fluctuations at harder energies are delayed with respect to the softer ones. The standard interpretation involves dependence of the X-ray spectral hardness on the radial distance, with harder spectra emitted closer to the black hole. Recently, a number of challenges to this scenario have been found, both at qualitative and quantitative level. The model does not predict the large magnitude of the delay between different energies, as well as the dependence of variability amplitude on the spectral range and frequency. We study timing properties of accreting black hole X-ray binaries taking into account peculiarities of spectral formation in these sources. We show that the simultaneous presence of two components leads to a complex shape of power spectra and phase lags between the X-ray bands: the amplitude of the phase lag becomes independent of the delay between the components, and the power spectra show an artificial decrease or, on the contrary, enhancement of power at low Fourier frequencies. This provides an essential ingredient for the reinstatement of the propagating fluctuations model. The work draws attention to the importance of considering conditions of spectral formation when studying timing properties.

description: Investigating the ``physics'' of food crises consists in identifying features which are common to all large-scale food crises. One element which stands out is the fact that during a food crisis there is not only a surge in deaths but also a correlative temporary decline in conceptions and subsequent births. As a matter of fact, birth reduction may even start several months before the death surge and can therefore serve as an early warning signal of an impending crisis. This scenario is studied in three cases of large-scale food crises. Finland (1868), India (1867--1907), China (1960--1961). It turns out that between the regional amplitudes of death spikes and birth troughs there is a power law relationship. This confirms what was already observed for the epidemic of 1918 in the United States (Richmond et al. 2018b). In a second part of the paper we explain how this relationship can be used for the investigation of mass-mortality episodes in cases where direct death data are either uncertain or nonexistent.

A major unsolved challenge in this kind of social science research is to devise a systematic way to compare, contrast, and communicate different models of social dynamics along relevant dimensions and characteristics, given the inherent complexity of most computational agent-based models. This article proposes a viable systematic framework for comparing models and illustrates its application using some of the models that Mel helped inspire and develop as senior project participant.

description: The high-confidence detection and identification of very low abundance, subpixel quantities of solid materials in nonlinear (intimate) mixtures are still significant challenges for HSI data analysis. Machine learning with convolutional neural networks (CNN) has proven to be an accurate means of identifying and typing features for various forms of data including estimating nonlinear functions and detecting features in one-dimensional data series. The application of CNNs to low abundance intimate mixtures, could improve minimum detectable quantities (MDQs) compared to current algorithms by processing spectra such that subtle features are enhanced and more discriminable. To test this, microscenes of three different intimate mixtures at varying abundance ratios (weight percent) were generated and measured using a benchtop shortwave infrared (SWIR) hyperspectral imager. A microscene is a hyperspectral image of a small-scale human-generated landscape measured in a laboratory. The 3 mixtures measured consisted of silicate sand + Nd2O3, silicate sand + powdered sugar, and soil + aspartame. Several hundred thousand labeled spectra are easily and rapidly generated in one HSI cube of a microscene for neural network training and testing. The mixture detection abilities of several processing methods were compared including deep learning (DL) CNNs in TensorFlow, shallow (non-convolutional) neural networks in both TensorFlow and MATLAB, and ENVI’s matched filter (MF), support vector machine (SVM), and linear spectral unmixing (LSU) functions. The CNN models for each mixture have >98 % average validation accuracies for detecting mixtures of varying abundances, including the lowest abundances measured. Both the DL/CNN and shallow neural networks tested showed increased detection capabilities compared to some more traditional ENVI methods. The networks were able to identify the lowest weight percent of sand + Nd2O3, but the MF and LSU methods did not yield results that would be considered reliable detections. The results establish confidence in using CNNs as a means of detecting low abundance intimate mixtures in real-world scenarios.

Publisher: name: Zenodo
Year: 2021

description: Cloud-Optimized Access to HDF5/NetCDF4 Files using Zarr and OPeNDAP

This presentation discusses optimizing cloud access for scientific data stored in HDF5/NetCDF4 formats.

Challenges:

Cloud storage has high latency compared to local storage, making frequent small reads inefficient.

Traditional file formats like NetCDF4 don't provide optimal chunking for cloud access.

Solutions:

Zarr format: Stores data in chunks with byte offsets, allowing direct access to specific data sections without reading the entire file.

OPeNDAP DMR++: Extends the Dataset Metadata Response protocol to include Zarr chunk information.

Hyrax server: Reads data from S3 using OPeNDAP DMR++ and Zarr metadata, enabling efficient data subsetting and retrieval.

Optimizations:

Combining adjacent chunks: Reduces the number of requests needed to retrieve larger data sections.

Parallel reads: Improves data transfer speed by reading multiple chunks simultaneously.

Decompressing chunks in parallel: Further optimizes data processing.

Caching handshake information: Avoids redundant authentication and redirection steps for subsequent requests.

Benefits:

Reduced latency: Faster data access compared to traditional methods.

Efficient data transfer: Minimizes unnecessary data downloads.

Improved scalability: Supports large datasets effectively.

Overall, this approach combines Zarr, OPeNDAP, and Hyrax to provide optimized cloud access for scientific data analysis.

Additional information:

The zarr-eosdis-store library is open-source and available on GitHub.

The presentation emphasizes the importance of read latency optimization for cloud data access.

description: In an attempt to bridge the gap between atomistic and continuum plasticity simulations of hydrogen in iron, we present three dimensional discrete dislocation plasticity simulations incorporating the hydrogen elastic stress and a hydrogen dependent dislocation mobility law. The hydrogen induced stress is incorporated following the formulation derived by Gu and El-Awady (2018) which here we extend to a finite boundary value problem, a microcantilever beam, via the superposition principle. The hydrogen dependent mobility law is based on first principle calculations by Katzarov et al. (2017) and was found to promote dislocation generation and enhance slip planarity at a bulk hydrogen concentration of 0.1 appm; which is typical for bcc materials. The hydrogen elastic stress produced the same behaviour, but only when the bulk concentration was extremely high. In a microcantilever, hydrogen was found to promote dislocation activity which lowered the flow stress and generated more pronounced slip steps on the free surfaces. These observations are consistent with the hydrogen enhanced localized plasticity (HELP) mechanism, and it is concluded that both the hydrogen elastic stress and hydrogen increased dislocation mobility are viable explanations for HELP. However it is the latter that dominates at the low concentrations typically found in bcc metals.

description: Much of the structure in social networks has been explained by two seemingly independent network evolution mechanisms: triadic closure and homophily. While it is common to consider these mechanisms separately or in the frame of a static model, empirical studies suggest that their dynamic interplay is the very process responsible for the homophilous patterns of association seen in off- and online social networks. By combining these two mechanisms in a minimal solvable dynamic model, we confirm theoretically the long-held and empirically established hypothesis that homophily can be amplified by the triadic closure mechanism. This research approach allows us to estimate how much of the observed homophily in various friendship and communication networks is due to amplification for a given amount of triadic closure. We find that the cumulative advantage-like process leading to homophily amplification can, under certain circumstances, also lead to the widely documented core-periphery structure of social networks, as well as to the emergence of memory of previous homophilic constraints (equivalent to hysteresis phenomena in physics). The theoretical understanding provided by our results highlights the importance of early intervention in managing at the societal level the most adverse effects of homophilic decision-making, such as inequality, segregation and online echo chambers.

description: A generalized Feynman-Kac formula based on the Wiener measure is presented. Within the setting of a quantum particle in an electromagnetic field it yields the standard Feynman-Kac formula for the corresponding Schrödinger semigroup. In this case rigorous criteria for its validity are compiled. Finally, phase-space path-integral representations for more general quantum Hamiltonians are derived. These representations rely on a generalized Lie-Trotter formula which takes care of the operator-ordering multiplicity, but in general is not related to a path measure.

description: The paper is an excursus on potential acid-base adducts formed by an unsaturated main group or transition metal species and P atoms of phosphorene (P n ), which derives from the black phosphorus exfoliation. Various possibilities of attaining a realistic covalent functionalization of the 2D material have been examined via DFT solid state calculations. The distribution of neighbor P atoms at one side of the sheet and the reciprocal directionalities of their lone pairs must be clearly understood to foreshadow the best possible acceptor reactants. Amongst the latter, the main group BH3 or I2 species have been examined for their intrinsic acidity, which favors the periodic mono-hapto anchoring at Pn atoms. The corresponding adducts are systematically compared with other molecular P donors from a phosphine to white phosphorus, P4. Significant variations emerge from the comparison of the band gaps in the adducts and the naked phosphorene with a possible electronic interpretation being offered. Then, the Pn covalent functionalization has been analyzed in relation to unsaturated metal fragments, which, by carrying one, two or three vacant sigma hybrids, may interact with a different number of adjacent P atoms. For the modelling, the concept of isolobal analogy is important for predicting the possible sets of external coligands at the metal, which may allow the anchoring at phosphorene with a variety of hapticities. Structural, electronic, spectroscopic and energy parameters underline the most relevant pros and cons of some new products at the 2D framework, which have never been experimentally characterized but appear to be reasonably stable.

description: According to the Department of Veterans Affairs’ 2018 Suicide Data Report, an average of 20 veterans commit suicide every day. The Army ACE Suicide Intervention Training is based on a battle buddy system and methods of observation for other soldiers in attempt to prevent suicide. The increasing number of suicides among soldiers indicates that the training is not persuasive enough for soldiers to overcome the stigma and seek help. This paper presents research into different methods of formulating suicide intervention training using a rhetorical approach to find improved ways to persuade soldiers who are dealing with intense stress or mental illness to speak up and ask for help.
title: The Differentiation of Muscle Containing Myofascial Trigger Points from Healthy Muscle Using Shear Wave Elastography

description: Myofascial trigger points (MTrPs) are palpable, painful nodules that develop in skele- tal muscle and are a characteristic finding in myofascial pain syndrome (MPS), a common chronic pain condition. Symptomatic MTrPs are frequently the target of therapeutic treat- ment for the management of MPS. However, the pathophysiology of MTrPs is poorly under- stood and the diagnostic criteria remain inconsistent. Based on previous investigations into MTrPs using ultrasound imaging, we hypothesized that muscles containing MTrPs have heterogeneous fiber orientation within the affected zone and surrounding areas compared to palpably normal muscle. For this study, we sought to utilize the known variation of shear wave speed with muscle fiber orientation as a method of determining anisotropy in muscle fibers. We developed a standardized method of acquiring shear wave elastography images at different transducer orientations using a custom transducer holder with a fixed imaging window. The holder was fitted over palpable MTrPs in the upper trapezius of patients suf- fering from chronic neck pain (>3 months). The transducer holder allowed for registration of the palpable MTrPs to any collected images. The variation of the shear wave speed of the muscle, as a function of the transducer angle, was used as a surrogate for muscle fiber orientation. The asymmetry of the fiber orientation was then determined and compared between active (spontaneously painful) MTrPs, latent (not spontaneously painful) MTrPs, and normal muscle tissue. The results of this study showed an increase in muscle fiber asymmetry with increasingly symptomatic muscle, with normal muscle having the lowest asymmetry (6.64 ± 7.23 °, N = 11), then latent MTrPs (11.51 ± 9.86 °, N = 22), and finally active MTrPs (14.19 ± 11.76 °, N = 40). A statistically significant difference was found between the normal and active MTrPs groups (p<0.014). This data suggests that disruption of muscle fiber architecture may be an important feature that distinguished active MTrPs from normal muscle tissue.
