description: Gauge invariant regularization of quantum field theory in the framework of Light-Front (LF) Hamiltonian formalism via introducing a lattice in transverse coordinates and imposing boundary conditions in LF coordinate $x^-$ for gauge fields on the interval $|x^-|\le L$ is considered. The remaining ultraviolet divergences in the longitudinal momentum $p_-$ are removed by gauge invariant finite mode regularization. We find that LF canonical formalism for the introduced regularization does not contain usual most complicated second class constraints connecting zero and nonzero modes of gauge fields. The described scheme can be used either for the regularization of conventional gauge theory or for gauge invariant formulation of effective low-energy models on the LF. The lack of explicit Lorentz invariance in our approach leads to difficulty with defining the vacuum state. We discuss this difficulty, particulary, in the connection with the problem of taking the limit of continuous space.

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: The ground-state and low-energy properties of the two-dimensional $J_1{-}J_2$ Heisenberg model in the collinear phase are investigated using finite-size spin-wave theory [Q. F. Zhong and S. Sorella, {\em Europhys. Lett.} {\bf 21}, 629 (1993)], and Lanczos exact diagonalizations. For spin one-half -- where the effects of quantization are the strongest -- the spin-wave expansion turns out to be quantitatively accurate for $J_2/J_1\gtrsim 0.8$. In this regime, both the magnetic structure factor and the spin susceptibility are very close to the spin-wave predictions. The spin-wave estimate of the order parameter in the collinear phase, $m^\dagger\simeq 0.3$, is in remarkable agreement with recent neutron scattering measurements on ${\rm Li_2VOSiO_4}$.

description: One of the sources of incompatibility between general relativity and quantum mechanics is perturbative non-renormalizability of quantum gravity in $3+1$ spacetime dimensions. Here, we show that in the presence of disorder induced by random networks of observers measuring covariant quantities (such as scalar curvature) $(3+1)$-dimensional quantum gravity exhibits an effective dimensional reduction at large spatio-temporal scales, which is analogous to the Parisi-Sourlas phenomenon observed for quantum field theories in random external fields. After averaging over associated disorder and focusing on the infrared dynamics of the theory we find that the upper critical dimension of quantum gravity is lifted from $D_{\rm cr}=1+1$ to $D_{\rm cr}=3+1$ dimensions.

description: This study used administrative records for 50,067 applications and 34,914 benefit spells in South Carolina for the period October 1996-November 2007 to examine households’ applications to and participation in the Supplemental Nutrition Assistance Program (SNAP). We modeled application resolutions where the possible outcomes were acceptance, denial due to income ineligibility, denial due to a failure to provide sufficient information, and denial for other reasons. For cases with successful applications, we modeled the durations of participation spells to distinguish among exits that result from missed recertifications, financial ineligibility, incomplete or missing information, and other reasons. The results indicate that a household’s application and participation history affect its subsequent application success and program tenure. Applicants with recent SNAP program experience are more likely to have their applications accepted than other applicants. Among the applicants with recent program experience, the way in which a previous spell ends helps to predict how their next application will be resolved and how their next participation spell will end. Households face an increased risk of having a SNAP participation spell end for financial ineligibility if an earlier participation spell ended for that reason. Similarly, households face an increased risk of having their applications denied or participation spells end for information deficiencies if an earlier spell ended that way.

description: Recent revisions to the food packages provided by the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) added healthy foods and required WIC-authorized stores to make these foods available. This study examined the availability, variety, and prices of healthy foods before and after implementation of the food package revisions in 252 convenience and nonchain grocery stores in Connecticut. The findings provide strong evidence that stores responded to the food package revisions by improving the availability and variety of healthy foods in both urban and suburban settings. Most of these improvements occurred in WIC-authorized convenience and grocery stores, especially those in low-income neighborhoods. Some positive changes in the availability of whole-grain products were also observed in non-WIC convenience and grocery stores. The policy change, which targets WIC participants, improved access to healthy foods for both WIC and non-WIC consumers.
Major Mergers of Galaxy Haloes: Cuspy or Cored Inner Density Profile?

description: We present the results from a series of collisionless N-body simulations of major mergers of galaxy dark matter haloes with density profiles having either inner cusps or cores. Our simulations range from 2x10^5 to 10^7 particles, allowing us to probe the phase-space distribution of dark matter particles in the innermost regions (less than 0.005 virial radii) of cold dark matter haloes, a subject of much recent debate. We find that a major merger of two cored haloes yields a cored halo and does not result in a cuspy profile seen in many cosmological simulations. This result is unchanged if we consider mergers with parent mass ratios of 3:1 instead of 1:1. Mergers of a cuspy halo with either a cored halo or a second cuspy halo of equal mass, on the other hand, produce cuspy haloes with a slightly reduced inner logarithmic slope. Cuspy haloes, once formed, therefore appear resilient to major mergers. We find the velocity structure of the remnants to be mildly anisotropic, with a Maxwellian velocity distribution near the centre but not in the outer portions of the final haloes. Violent relaxation is effective only during the early phase of mergers, with phase mixing likely to be the dominant relaxation process at late times.

description: We investigate a lattice-fluid model defined on a two-dimensional triangular lattice, with the aim of reproducing qualitatively some anomalous properties of water. Model molecules are of the "Mercedes Benz" type, i.e., they possess a D3 (equilateral triangle) symmetry, with three bonding arms. Bond formation depends both on orientation and local density. We work out phase diagrams, response functions, and stability limits for the liquid phase, making use of a generalized first order approximation on a triangle cluster, whose accuracy is verified, in some cases, by Monte Carlo simulations. The phase diagram displays one ordered (solid) phase which is less dense than the liquid one. At fixed pressure the liquid phase response functions show the typical anomalous behavior observed in liquid water, while, in the supercooled region, a reentrant spinodal is observed.

A new method for measurement and quantification of tracer diffusion in nanoconfined liquids

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We report development of a novel instrument to measure tracer diffusion in water under nano-scale confinement. A direct optical access to the confinement region, where water is confined between a tapered fiber and a flat substrate, is made possible by coating the probe with metal and opening a small aperture( 0.1 $μ$m to 1 $μ$m) at its end. A well-controlled cut using an ion beam ensures desired lateral confinement area as well as adequate illumination of the confinement gap. The probe is mounted on a tuning-fork based force sensor to control the separation between the probe and the substrate with nm precision. Fluctuations in fluorescence intensity due to diffusion of a dye molecule in water confined between probe and the sample are recorded using a confocal arrangement with a single photon precision. A Monte-Carlo method is developed to determine the diffusion coefficient from the measured autocorrelation of intensity fluctuations which accommodates the specific geometry of confinement and the illumination profile. The instrument allows measurement of diffusion laws under confinement. We found that the diffusion of a tracer molecule is slowed down by more than ten times for the probe-substrate separations of 5 nm and below.

description: This study uses administrative records from participants in a longitudinal study of low-income families in three U.S. cities to determine whether enrollment in the Food Stamp Program increased in households with U.S.-born children and foreign-born heads after legal immigrants’ access to the program was restored under the Farm Bill Act of 2002. The analysis includes cross-tabulation, graphical comparisons, and multivariate Cox proportional hazard models predicting the risk of program entry and program exit. Results indicate that there was a short-term spike in the likelihood of enrollment by households headed by noncitizen parents immediately after the Farm Bill Act was fully implemented in October 2003. For this population, the likelihood of enrollment declined by April 2004, but participation in the post-Farm Bill Act era remained elevated through 2006 compared with prior periods.
Momentum-dependent potential and collective flows within the relativistic quantum molecular dynamics approach based on relativistic mean-field theory

description: Relativistic quantum molecular dynamics based on the relativistic mean field theory (RQMD.RMF) is extended by including momentum-dependent potential. The equation of state (EoS) dependence of the directed and the elliptic flow of protons in the beam energy range of $2.3 < \sqrt{s_{NN}}< 20$ GeV is examined. It is found that the directed flow depends strongly on the optical potential at high energies,$\sqrt{s_{NN}} > 3 $ GeV, where no information is available experimentally. The correlation between effective mass at saturation density and the optical potential is found: smaller values of effective mass require smaller strengths of the optical potential to describe the directed flow data.This correlation can also be seen in the beam energy dependence of the elliptic flow at $\sqrt{s_{NN}}>3$ GeV, although its effect is rather weak. On the other hand, stiff EoS is required to describe the elliptic flow at lower energies.Experimental constraints on the optical potential from $pA$ collisions will provide important information on the EoS at high energies.The proton directed and the elliptic flow are well described in the RQMD.RMF model from $\sqrt{s_{NN}}=2.3$ to 8.8 GeV. In contrast,to reproduce the collapse of the directed flow above 10 GeV, pressure has to be reduced, which indicates a softening of the EoS around $\sqrt{s_{NN}} =10 $ GeV.

description: We study the finite-temperature properties of the supersymmetric version of (2+1)D Georgi-Glashow model. As opposed to its nonsupersymmetric counterpart, the parity symmetry in this theory at zero temperature is spontaneously broken by the bilinear photino condensate. We find that as the temperature is raised, the deconfinement and the parity restoration occur in this model at the same point $T_c=g^2/8π$. The transition is continuous, but is not of the Ising type as in nonsupersymmetric Georgi-Glashow model, but rather of the Berezinsky-Kosterlitz-Thouless type as in $Z_4$-invariant spin model.

description: We link causally the riskiness of men's management of their finances with the probability of their experiencing a divorce. Our point of departure is that when comparing single men to married men, the former manage their finances in a more aggressive (that is, riskier) manner. Assuming that single men believe that low relative wealth has a negative effect on their standing in the marriage market and that they care about their standing in that market more than married men do, we find that a stronger distaste for low relative wealth translates into reduced relative risk aversion and, consequently, into riskier financial behavior. With this relationship in place we show how this difference varies depending on the "background" likelihood of divorce and, hence, on the likelihood of re-entry into the marriage market: married men in environments that are more prone to divorce exhibit risk-taking behavior that is more similar to that of single men than married men in environments that are little prone to divorce. We offer a theoretical contribution that helps inform and interpret empirical observations and regularities and can serve as a guide for follow-up empirical work, having established and identified the direction of causality.

description: The experimentally observed difference of superconducting critical temperature $T_{c}$ in hole-doped cuprates is studied by using an extended interlayer coupling model for layered d-wave superconductors. We show that the change of the maximum $T_{c}$ from series to series is determined by the next nearest neighboring hopping $t^{\prime}$, while the difference of the maximum $T_{c}$ among the compounds in a homogeneous series is controlled by the interlayer pairing strength. Our results provide helpful guidelines in the search for new high-$T_{c}$ superconductors.

Publisher: name: Zenodo
Year: 2024

description: This research is aimed at conducting a sensitivity study, evaluating the performance of Bayesian estimators against Bayesian ridge methods under conditions of multicollinearity. The Bayesian schemes involves the introduction of a prior together with the likelihood which resulted in the posterior distribution that is not tractable, hence the use of numerical method i.e Gibbs sampler. Different ridge parameters k were introduced to remedy the effect of multicollinearity .Pena data was used  to carry out Sensitivity analysis varying the priors with Bayesian estimate only ,Bayesian with Hoerl and Kennard ridge, Bayesian with Fayose and Ayinde ridge and Lukman and Ayinde ridge. The trace plot was draw for convergence.The sensitivity of the different priors were examined  to know the impact of the priors, how sensitive the estimators are in the presence of multicollinearity. The introduction of Bayesian ridge estimators using different ridge parameter estimators shows promising improvement since the values of the estimates become more stable than the Bayesian estimator without multicolinearity, especially, for Lukman and Ayinde (2017) estimators which makes a good estimator to be used. The Trace plot shows relatively stable horizontal mean and variance, indicating convergence.

description: Morphometric analysis of the inner ear of mammals can provide information for cochlear frequency mapping, a species-specific designation of locations in the cochlea at which different sound frequencies are encoded. Morphometric variation occurs in the hair cells of the organ of Corti along the cochlea, with the base encoding the highest frequency sounds and the apex encoding the lowest frequencies. Changes in cell shape and spacing can yield additional information about the biophysical basis of cochlear tuning mechanisms. Here, we investigate how morphometric analysis of hair cells in mammals can be used to predict the relationship between frequency and cochlear location. We used linear and geometric morphometrics to analyze scanning electron micrographs of the hair cells of the cochleae in Parnell’s mustached bat (Pteronotus parnellii) and Wistar rat (Rattus norvegicus) and determined a relationship between cochlear morphometrics and their frequency map. Sixteen of twenty-two of the morphometric parameters analyzed showed a significant change along the cochlea, including the distance between the rows of hair cells, outer hair cell width, and gap width between hair cells. A multiple linear regression model revealed that nine of these parameters are responsible for 86.9% of the variation in these morphometric data. Determining the most biologically relevant measurements related to frequency detection can give us a greater understanding of the essential biomechanical characteristics for frequency selectivity during sound transduction in a diversity of animals.

Generalisations of that theorem and the Nullstellensatz to symmetric products are discussed.Applications to the theory of multi-symmetric functions are also discussed. It is proved that the first three characters determine the Jordan algebra associated to a Frobenius algebra and as a corollary one obtains the theorem of Hoehnke and Johnson that a finite group is determined by the first three characters of its regular representation.

This article analyzes the manifestations of customer communication culture through traditional business forms (such as craft villages) and modern business forms (such as e-commerce platforms). It highlights significant changes in the communication culture of small businesses and companies. These changes demonstrate that the digital economy is a strong driver for evolving customer communication culture in particular and business culture in general in Vietnam. The research also proposes recommendations to promote customer communication culture for traditional products that embody Vietnam’s cultural identity and advantages.

description: Many fundamental biological processes are regulated by protein-DNA complexes called {\it synaptosomes}, which possess multiple interaction sites. Despite the critical importance of synaptosomes, the mechanisms of their formation remain not well understood. Because of the multi-site nature of participating proteins, it is widely believed that their search for specific sites on DNA involves the formation and breaking of DNA loops and sliding in the looped configurations. In reality, DNA in live cells is densely covered by other biological molecules that might interfere with the formation of synaptosomes. In this work, we developed a theoretical approach to evaluate the role of obstacles in the target search of multi-site proteins when the formation of DNA loops and the sliding in looped configurations are possible. Our theoretical method is based on analysis of a discrete-state stochastic model that uses a master equations approach and extensive computer simulations. It is found that the obstacle slows down the search dynamics in the system when DNA loops are long-lived, but the effect is minimal for short-lived DNA loops. In addition, the relative positions of the target and the obstacle strongly influence the target search kinetics. Furthermore, the presence of the obstacle might increase the noise in the system. These observations are discussed using physical-chemical arguments. Our theoretical approach clarifies the molecular mechanisms of formation of protein-DNA complexes with multiple interactions sites.

description: In 2018, China retaliated to U.S. trade action by levying a 25% retaliatory tariff on U.S. soybean exports. That tariff shifted market preferences so that Chinese buyers favored Brazilian soybeans. We use the relative price of a substitute (RPS) method to estimate that the resulting trade disruption effectively drove a wedge into the world soybean market, lowering U.S. prices at Gulf export locations by $0.65/bu on average for about five months, and increasing Brazilian prices by about $0.95/bu, compared to what would have been observed without the tariff in place. It is likely that the impact of China’s tariff on producers and purchasers of soybeans across the United States was heterogeneous and affected by local factors like transportation infrastructure, storage capacity, and crush facility proximity.

description: This report describes the individual and household characteristics of low-income middle-aged and older women with childrearing responsibilities and documents the extent to which they receive food stamps and other public assistance benefits. The analysis is based on 1,756 low-income women in Boston, Chicago, and San Antonio who were primary caretakers of minor children when first surveyed in 1999, and who were subsequently interviewed again in 2001 and 2005. We find that older and younger low-income women in this sample were similar in most respects but that women in the older age group were more likely than the younger women to be grandmothers caring for grandchildren and reported more health and disability issues. The analysis also indicates that food stamps were the most common public benefit received but was received more by women in the younger cohort, suggesting that greater outreach may be worth considering for older caregiver women.

description: We discuss systematic approaches to the classification of string/M theory vacua, and physical questions this might help us resolve. To this end, we initiate the study of ensembles of effective Lagrangians, which can be used to precisely study the predictive power of string theory, and in simple examples can lead to universality results. Using these ideas, we outline an approach to estimating the number of vacua of string/M theory which can realize the Standard Model.

description: The USDA Economic Research Service has developed national and state-level agricultural productivity measures. These productivity measures are widely referred to and used, and international sectoral comparisons rely on the ERS production accounts for foundation methodology in constructing agricultural productivity accounts in other countries. ERS engaged an external review committee to examine the data sources, methodology, ongoing research, documentation, and reporting of the ERS agricultural productivity accounts. This report represents the outcome of that review.

description: Superconductivity arises from two distinct quantum phenomena: electron pairing and long-range phase coherence. In conventional superconductors, the two quantum phenomena generally take place simultaneously, while the electron pairing occurs at higher temperature than the long-range phase coherence in the underdoped high-Tc cuprate superconductors. Recently, whether electron pairing is also prior to long-range phase coherence in single-layer FeSe film on SrTiO3 substrate is under debate. Here, by measuring Knight shift and nuclear spin-lattice relaxation rate, we unambiguously reveal a pseudogap behavior below Tp ~ 60 K in two layered FeSe-based superconductors with quasi-two-dimension. In the pseudogap regime, a weak diamagnetic signal and a remarkable Nernst effect are also observed, which indicate that the observed pseudogap behavior is related to superconducting fluctuations. These works confirm that strong phase fluctuation is an important character in the two-dimensional iron-based superconductors as widely observed in high-Tc cuprate superconductors.

description: Οι ψυχιατρικές εκδηλώσεις στην Πολλαπλή Σκλήρυνση (ΠΣ) αποτελούν αξιοσημείωτη πλευρά της νόσου. Από την εποχή που ο Charcot περιέγραψε την Πολλαπλή Σκλήρυνση ως ξεχωριστή νοσολογική οντότητα (19ος αιώνας) , συμπεριέλαβε στην περιγραφή της ψυχωσικά συμπτώματα. Από τότε, και κυρίως μετά την καθιέρωση της MRI ως εξέταση εκλογής για την ΠΣ (μετά τη δεκαετία του ‘90) , πραγματοποιήθηκαν μελέτες που αφορούν τις ψυχιατρικές εκφάνσεις της νόσου και πώς αυτές επηρεάζουν τη ζωή των ΠΣ ασθενών. Οι συχνότερα εμφανιζόμενες συννοσηρότητες είναι το σύμπτωμα της χρόνιας κόπωσης (“fatigue”) και η κατάθλιψη, με διάφορες άλλες ψυχικές νόσους να ακολουθούν πχ. άγχος, σχιζοφρένεια, διπολική διαταραχή κλπ. Ακόμα, ρόλο στην εμφάνιση ψυχιατρικών συμπτωμάτων στην ΠΣ φαίνεται να διαδραματίζουν και οι θεραπείες τη ΠΣ(DMTs). Στην παρούσα εργασία, πραγματοποιήθηκε βιβλιογραφική ανασκόπηση των ψυχιατρικών εκδηλώσεων της ΠΣ και ταξινόμηση τους ανάλογα με τη συχνότητα και τη βαρύτητα τους. Αναλυτικότερα, έγινε προσπάθεια περιγραφής της αλληλεπίδρασης ΚΝΣ-ανοσοποιητικού συστήματος , όσον αφορά την εκδήλωση ψυχικών νόσων και πώς αυτό πιθανώς συσχετίζεται με την ΠΣ. Επιπρόσθετα, προτάθηκαν οι πιθανοί τρόποι αντιμετώπισης των ψυχιατρικών εκφάνσεων της ΠΣ. Τέλος, εξάχθηκαν ορισμένα συμπεράσματα όσον αφορά την ψυχιατρική πλευρά της ΠΣ
description: Psychiatric manifestations in Multiple Sclerosis are a remarkable aspect of the disease. When Charcot first described MS as a seperate pathological entity (19th century), he included psychotic symptoms in his description. Since then, and especially after the establishment of MRI as the examination of choice for MS(after the 90s), studies have been carried out regarding the psychiatric manifestations of the disease and how they affect lives of MS patients. The most frequently occurring comorbidities are the symptom of chronic “fatigue” and depression, with various other psychiatric diseases following , e.g., anxiety, schizophrenia, bipolar disease etc. Furthermore , the development of DMTs and their establisment as a primary therapy of MS have also played role in psychiatric disturbances of this disease. In this MSc thesis, a literature review of psychiatric manifestations of MS and their classification according to their frequency and severity were carried out. More specifically, interactions between CNS and immune system were described to show the immunological pathways of psychiatric diseases and how they relate with the onset, outcome, and severity of MS. Additionally, possible treatments for the psychiatric disturbances of MS were suggested. Finally, some conclusions were drawn reagarding the psychiatric side of MS

description: The Economic Research Service’s (ERS’s) Loss-Adjusted Food Availability (LAFA) data series is derived from ERS’s Food Availability (FA) data by adjusting for food spoilage, plate waste, and other losses to more closely approximate actual intake. ERS refers to the LAFA data series as preliminary and recognizes the need to systematically update and improve the loss assumptions underlying the LAFA per capita availability estimates. The goal of this project was to develop recommendations to improve the integrity, transparency, and validity of the LAFA data series and build on lessons learned from prior efforts. The overall objective was to research and recommend workable, concrete solutions to technical questions underlying the data and to close data gaps. In collaboration with RTI International, a team of four academic experts reviewed background materials, examined current data, searched for and analyzed alternative data sources, and developed recommendations for the set of technical questions and data gaps provided by ERS. We prioritized the recommendations based on our assessment of ease of implementation and effect on improving the LAFA data series.
