description: Charge separation induced by the chiral magnetic effect suggested that some ${\cal P}$- or ${\cal CP}$-odd metastable domains could be produced in a QCD vacuum in the early stage of relativistic heavy-ion collisions. Based on a multi-phase transport model, our results suggest that a domain-based scenario with final state interactions can describe the solenoidal tracker at RHIC detector (STAR) measurements of both same- and opposite-charge azimuthal angle correlations, $$, in Au+Au collisions at $\sqrt{s_{_{\rm NN}}}=200$ GeV. The occupancy factor of the total volume of domains over the fireball volume is small, which indicates that the size and number of metastable domains should be relatively small in the early stage of a quark-gluon plasma.

Day Care Centers in Lesotho
Creators: name: Bhila, Takura
Publisher: name: figshare
Year: 2022
Subjects: Environmental management

description: For the average working class family in Lesotho, the children spend eight to ten hours per day in day care centres for the first five years of their lives. With the rise in problems linked to the environment, health and development in children, creating a conducive, nurturing and healthy living space in day care centres is paramount. In the construction of day care centres, care should be exercised to avoid exposing children to substances like chemicals, toxins in building materials and interior finishes. These pose danger to children’s neurological (nervous) system’s development. This study therefore explores the green design alternative since it is an approach to building that minimizes negative impacts on human health and the natural environment by choosing eco-friendly building materials and building practices. The study was a case study of Lesotho Daycare Community Preschool (LDCP) as well as document analysis of day care center development in Lesotho. This included descriptions and explanations from studies related to the subject. Observations, interviews with day care centre owners, interviews with ministry of education and training officials and study of visual documents of community preschool general designs also helped gather information. Findings suggested that the use of non toxic building materials and good designs for ventilation systems enhance children’s physical and mental development.

description: We derive a semi-classical effective action and the kinetic equation for massive Dirac fermions in electromagnetic fields. The non-Abelian Berry phase structure emerges from two helicity states of massive fermions with positive energy. The classical spin emerges as a vector in SU(2) helicity space. The continuity equations for the fermion number and the classical spin are derived. The fermion number is conserved while the spin charge is not conserved by anomaly. Previous results about the coefficients of the chiral magnetic effect for the fermion and axial currents in the chiral limit can be reproduced after including the anti-fermion contributions. This provides an example for the emerging spin and non-Abelian Berry phase of Dirac fermions arising from the fermion mass.

HUME COME TEORICO DELLA VIRTÙ: VARIETÀ E DIFFERENZE D’INTERPRETAZIONE
Creators: name: GRECO, LORENZO
Publisher: name: Dipartimento di Scienze Umane, Università di Ferrara
Year: 2019
Subjects: Hume, Virtue Ethics, Neo-Aristotelians, Response-Dependence, Situationism, Pluralism.

description: This essay compares various attempts of interpreting Hume’s morality as a form of virtue ethics, focusing in particular on those ones recently made by some neo-Aristotelian philosophers. It considers Philippa Foot, Rosalind Hursthouse, Julia Annas, and Alasdair MacIntyre, and it maintains that they all misunderstand Hume as a virtue theorist. It also examines, and rejects, Christine Swanton’s response-dependent take on Hume. This essay offers an alternative understanding of Humean virtue ethics that depends on contingency, pluralism, and the mixed nature of human character. By doing this, it highlights the importance individuality plays in Humean virtue ethics as a value to be preserved and defended.

Publisher: name: arXiv

Subjects: subject: Disordered Systems and Neural Networks (cond-mat.dis-nn)
subject: FOS: Physical sciences

description: We study the dynamics of excitations in a system of $O(N)$ quantum rotors in the presence of random fields and random anisotropies. Below the lower critical dimension $d_{\mathrm{lc}}=4$ the system exhibits a quasi-long-range order with a power-law decay of correlations. At zero temperature the spin waves are localized at the length scale $L_{\mathrm{loc}}$ beyond which the quantum tunneling is exponentially suppressed $ c \sim e^{-(L/L_{\mathrm{loc}})^{2(θ+1)}}$. At finite temperature $T$ the spin waves propagate by thermal activation over energy barriers that scales as $L^θ$. Above $d_{\mathrm{lc}}$ the system undergoes an order-disorder phase transition with activated dynamics such that the relaxation time grows with the correlation length $ξ$ as $τ\sim e^{C ξ^θ/T}$ at finite temperature and as $τ\sim e^{C' ξ^{2(θ+1)}/\hbar^2}$ in the vicinity of the quantum critical point.

title: An Evaluation of U.S. Horseback Riding Instruction Certifications: Availability, Acquisition, Barriers, and Industry Need
Creators: name: Osborne, Makenna L.
Publisher: name: Utah State University
Year: 2023

description: The purpose of this mixed-methods study is to analyze the U.S. equine industry’s availability of riding instruction certification options, describe the relationship between professional certification and the self-efficacy of horseback riding instructors in the U.S., and explore the expectations that consumers have of instructors and instructor selection criteria. Two surveys were developed and sent out to instructors and consumers aligned with the research objectives designed to collect information on instructors’ self- perception of self-efficacy after certifying their perceived barriers to receiving certification, and consumers’ selection criteria for instructors. The average certified instructor was extremely satisfied with their decision to pursue certification and achieve certification, and the perception of improvement of self-efficacy for the average certified instructor showed that the respondent believed very strongly that the process of receiving a certification improved their self-efficacy. The top three barriers perceived by instructors to obtaining certification were the expense, time, and geographic inaccessibility to workshops. Consumers seek instructors with high levels of horsemanship skills and soft skills, as well as competition experience in specific disciplines, with certification being the fifth most important out of seven characteristics. The results of this study will help professional organizations, third-party stakeholders, and post-secondary education in the development of programming aimed toward certification acquisition for professional riding instruction.
title: Differential Cross Section for Electron Positron Pair Production From Neutron Proton Scattering
Creators: name: Wheeler, Robert Dalton
Publisher: name: Utah State University
Year: 1968

description: The differential cross section for a neutron-proton collision forming an electron-positron pair is calculated. The interaction between the neutron and proton is assumed to be pseudo-scalar and that between the proton and the pair electromagnetic. The interaction between the pair and the neutron is assumed negligible.
The methods used to obtain the matrix elements of the process follows that of Möller. The calculation is therefore based on retarded interaction and is relativistic. In obtaining the square of the matrix elements the initial and final polarization states were not considered. The usual projection operator methods were then applied to the intermediate states which led to traces and trace products.
The traces were calculate on an IBM 7090 computer with the read-out being of alphabetic form. The output consisted of dot products of four vectors, with the four factors specifying the energy and momentum of the various particle states.
A second computer program was written to determine the momentum and energy among the particle states for a special symmetrical scattering case. The data obtained from this program was used as input for a third computer program which obtained a plot of differential cross section versus incident proton energy, the proton energy running from 960 Mev to 1065 Mev.
The results depicted by the graphs are discussed and additional work recommended.

title: A Study of Controlled Attention in Children With and Without Developmental Language Disorder
Creators: name: Alva, Logan
Publisher: name: Utah State University
Year: 2023

description: This study compared school-aged children with and without developmental language disorder (DLD) on five measures of language, auditory working memory (AWM), and controlled attention (CATT) accuracy, and CATT response time (RT). These measures were gathered from twenty-eight children, between 9 and 14 years of age, and were analyzed using crossed random effect analyses and Pearson correlations. The results suggest that children with DLD are significantly less accurate in their CATT abilities, but not necessarily slower when compared to their typically developing (TD) peers. Also, significant relationships were revealed between CATT accuracy and the language measures used for both children with and without DLD. This supports the idea that children with DLD have general limitations in their attentional control abilities, not necessarily a slower processing speed, and provides evidence in support of theories of language development and language disorder that highlight the role of cognitive abilities.

description: Peripheral nerve blocks (PNB) play nowadays an important role in perioperative pain management, both in human and in veterinary medicine. Several approaches have been described and validated in companion animals undergoing especially orthopaedic surgeries. Thus, considering the state of art in veterinary medicine, studies presented in this dissertation focus on pain management relate to soft tissue surgeries and medical conditions. An ultrasound-guided approach was used to assess cervical plexus block (US-CPB) in dog cadavers and to preliminary assess spermatic cord block (US-SCB) in dogs undergoing orchiectomy. A Neurostimulated approach to mandibular and facial nerves was assessed in dogs and rabbits undergoing total ear canal ablation and lateral bulla osteotomy (TECALBO). Furthermore, a different technique was described as a case report in a rabbit undergoing partial ear canal ablation and lateral bulla osteotomy (PECA-LBO), considering the different surgical technique used and the individual and specie-specific characteristics. Blind celiac plexus block is reported in a dog to manage severe pain related to acute pancreatitis irresponsive to conventional systemic analgesia. All these new techniques resulted to be feasible and those assessed in a clinical setting showed enhancement in anaesthetic stability and pain management, appearing to have promising application in clinical practice.

description: Let I be an ideal of a regular local ring Q with residue field k. The length of the minimal free resolution of R=Q/I is called the codepth of R. If it is at most 3, then the resolution carries a structure of a differential graded algebra, and the induced algebra structure on $Tor_Q(R,k) provides for a classification of such local rings. We describe the Macaulay2 package CodepthThree that implements an algorithm for classifying a local ring as above by computation of a few cohomological invariants.

RESUMMATION AND MACHINE LEARNING TECHNIQUES TOWARDS PRECISION PHENOMENOLOGY AT THE LHC
Creators: name: RABEMANANJARA, TANJONA RADONIRINA
Publisher: name: Universit� degli Studi di Milano
Year: 2021

description: The present thesis focuses on three distinct yet complementary areas in QCD. The first area concerns the resummation of large logarithmic contributions appearing in transverse momentum distributions. In particular, we focus on the hadroproduction of colour singlet final states such as Higgs boson produced via gluon fusion and the production of a lepton-pair via Drell--Yan mechanism. We present phenomenological studies of a combined resummation formalism in which standard resummation of logarithms of Q/pT is supplemented with the resummation of logarithmic contributions at large x. In such a formalism, small-pT and threshold logarithms are resummed up to NNLL and NNLL* respectively. The second area concerns the construction of an approximate NNLO expression for the transverse momentum spectra of the Higgs boson production by exploiting the analytical structure of various resummed formulae in Mellin space. The approximation we construct relies on the combination of two types of resummations, namely threshold and high-energy (or small-x). Detailed phenomenological studies, both at the partonic and hadronic level, are presented. And finally, the third area concerns the a posteriori treatment of Parton Distribution Functions (PDFs), specifically the compression of Monte Carlo PDF replicas using techniques from deep generative models such as generative adversarial models (or GANs in short). We show that such a GAN-based methodology results in a compression methodology that is able to provide a compressed set with smaller number of replicas and a more adequate representation of the original probability distribution. The possibility of using this methodology to address the problem of finite size effects in PDF determination is also investigated.
title: Patterns and Processes of Population Differentiation in the Chuckwalla (Sauromalus obesus) in Southern Nevada

Publisher: name: Utah State University
Year: 2002

description: I examined both present-day and historical patterns in the herbivorous desert lizard, Sauromalus obesus (chuckwalla), within the Mojave Desert ecoregion in Nevada. My goal was to determine the process or processes that led to their present-day distribution. I expected to recover distinct haplotypes unique to each mountain range. These unique haplotypes were expected to reveal a pattern of geographic partitioning with sequence divergence among populations increasing as a function of distance. I characterized the distribution of chuckwallas in Nevada by means of a simple model using a geographic information system (GIS). This simple model was used to enhance sampling efficiency for the genetic study over a broad geographic area. The model predicted chuckwalla habitat to be patchy and within mountain ranges. The model correctly predicted habitat that contained chuckwallas with 86% accuracy. I used areas predicted by the model as my sample units for a phylogenetic analysis of mitochondrial DNA (mtDNA) haplotypes using maximum parsimony and likelihood methods. These traditional methods revealed support for two clades: one including chuckwallas largely from the Newberry Mountains and the other including all the other populations surveyed. Apart from these two clades, the analyses were unable to resolve relationships among the populations within the two major clades. In order to resolve any relationships within the clades, I used an analytical method that involves an overlay of geography on an estimated gene tree in a rigorous statistical framework that measures the strength of any geography/phylogeny associations. I inferred from the analysis two major events for chuckwalla populations surveyed in this study: a recent post-Pleistocene contiguous range expansion from southern Sonoran refugia north into the Mojave by way of the Muddy and Virgin river drainages, followed by local differentiation because of lack of present-day gene flow. This pattern is supported by paleoecological evidence from packrat middens that indicates chuckwallas have only been in the northern Mojave during the last 10,000 years.

description: Since the time of Socrates, there has been no shortage of important philosophers who have not written anything. Only Hume, however, left us a story of his life, before publishing anything. The intellectual bibliography of James Harris is a remarkable feat and A.M. Stewart is the author of essays of exceptional value. However, the author of this paper disagrees with both on the ge­nesis of his Treatise of human nature. In his critical edition, David Fate Norton has left us 300 pages of references to texts that may have inspired the Trea­­tise. The author discovers some serious gaps. Similar is the case of a note by Beauchamp on sympathy in Hume’s Inquiry concerning the Principle of Morals.

description: Hume’s reception in German philosophy is rather important throughout the 18thand 19thcentury, where the Scottish philosopher plays different roles. Schelling too refers to Hume and most interestingly in his late lessons on the Philosophy of Mythology. Here Schelling revaluates the importance of Hume’s position on mythology – presented in the Dialogues concerning Natural Religion– stating that he correctly acknowledges the religious origin of mythology. Nonetheless, Schelling judges Hume’s position eventually equivocal, as he would be unable to free himself from his conception that correct religiosity is uniquely expressed by “philosophical theism”. Thanks to the critique to the limits of Hume’s position Schelling can ultimately formulate his own philosophical proposal for interpreting the origin of both polytheism and monotheism from a previous form of “monotheolatrism”.

description: A linearised kinetic equation describing electrostatic perturbations of a Maxwellian equilibrium in a weakly collisional plasma forced by a random source is considered. The problem is treated as a kinetic analogue of the Langevin equation and the corresponding fluctuation-dissipation theorem is derived. This kinetic fluctuation-dissipation theorem reduces to the standard "fluid" one in the regime where the Landau damping rate is small and the system has no real frequency; in this case the simplest possible Landau-fluid closure of the kinetic equation coincides with the standard Langevin equation. Phase mixing of density fluctuations and emergence of fine scales in velocity space is diagnosed as a constant flux of free energy in Hermite space; the fluctuation-dissipation theorem for the perturbations of the distribution function is derived, in the form of a universal expression for the Hermite spectrum of the free energy. Finite-collisionality effects are included. This work is aimed at establishing the simplest fluctuation-dissipation relations for a kinetic plasma, clarifying the connection between Landau and Hermite-space formalisms, and setting a benchmark case for a study of phase mixing in turbulent plasmas.

Higgs vacua with potential barriers

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Scenarios in which the Higgs vacuum arises radiatively and is separated from the origin by a potential barrier at zero temperature are known to be attainable in models with extra singlet scalars, which in the limit of zero barrier height give rise to Coleman-Weinberg realizations of electroweak symmetry breaking. However, this requires large values of Higgs-portal couplings or a large number N of singlets. This is quantified in detail by considering, for varying N, the full two-loop effective potential at zero temperature, as well as finite temperature effects including the dominant two-loop corrections due to the singlets. Despite the large couplings, two-loop effects near the electroweak scale are under control, and actually better behaved in models with larger couplings yet fewer singlets. Strong first-order phase transitions are guaranteed even in the Coleman-Weinberg scenarios. Cubic Higgs couplings and Higgs associated-production cross sections exhibit deviations from the Standard Model predictions which could be probed at a linear collider.

title: A Generative Neural Network for Discovering Near Optimaldynamic Inductive Power Transfer Systems
Creators: name: Chowdhury Oni, Md Shain Shahid
Publisher: name: Utah State University
Year: 2023

description: An urgent need is to electrify transportation to lower carbon emissions into the atmosphere. Wireless charging makes electrical vehicles (EVs) more convenient and cheaper because energy is transferred to the vehicle without the need to plug it in. Dynamic wireless charging is particularly interesting, where the vehicle does not need to stop to receive the energy. This technology requires the EV and the roadway to include coils of wire, where the roadway coil is energized as the vehicle passes over it to induce an electrical current in the EV coil through electromagnetic induction. However, the problem of designing the two coils (EV and road) is complex due to the many configurations possible, the need to maximize power transfer, and the need to minimize stray, possibly dangerous, electromagnetic fields during operation.
Current methods for designing inductive power transfer (IPT) coils rely heavily on FEM (finite-element methods) simulations to evaluate each potential design. Dynamic IPT design requires multiple simulation runs as the EV coil passes over the roadway coil. Identifying optimal designs is difficult because of the many conflicting specifications and objective functions that need to be considered, such as maximizing the output power while minimizing stray magnetic fields and the volume of windings and magnetic cores.
This work introduces a new design optimization method for dynamic IPT systems that utilize generative neural networks. Deep learning is applied to create a generator of near-optimal design alternatives from random noise. Two neural networks are employed in the approach. The first neural network is trained from multiple FEM results through random sampling of the design space and then replaces FEM calculations, allowing rapid simulation and evaluation of alternative designs. By using the neural network as a surrogate model rather than FEM to evaluate designs, differentiable programming approaches may be applied to train the second neural network to generate better designs. This generative network is trained by minimizing a loss function based on the optimization criteria listed earlier. Alternative loss function based on combining multi-objective optimization methods are explored, including applying the following mathematical operations over the objective functions: the sum of squares, a product of means, and sums of combinations of pair-wise products.
Compared to previous work [1], which employed genetic algorithm approaches, the generative network quickly learned to produce designs that pass all objective functions using the product of means, however, the design solutions lacked diversity. Interestingly, when considering all pairwise product combinations only a few worked in quickly learning to produce satisfactory solutions. Those combinations that worked had a lower solution production rate than the product of means but exhibited a higher diversity of solutions.

description: We show injectivity of the X-ray transform and the $d$-plane Radon transform for distributions on the $n$-torus, lowering the regularity assumption in the recent work by Abouelaz and Rouvière. We also show solenoidal injectivity of the X-ray transform on the $n$-torus for tensor fields of any order, allowing the tensors to have distribution valued coefficients. These imply new injectivity results for the periodic broken ray transform on cubes of any dimension.

description: Problematic and challenging student behavior has a myriad of negative outcomes for both educators and students. Although the implementation of Evidence Based Practices for classroom management have decreased these negative outcomes, educators are not utilizing them. The purpose of this study was to investigate which resources K-6 General Educators and Special Educators access to find information on behavior management strategies and procedures, as well as, their perceptions on those resources. We surveyed teachers from fourteen states in regards to what resources they used and the level in which they trusted, could implement, could understand and could find information on behavior management procedures from the resources they reported accessing. Results indicated that educators primarily accessed information from building/district administrators and colleagues due to their perceived accessibility, understandable, trustworthy and usable

 Abstract and figures
 The dimensional, geometrical, thermal and tool deflection errors which have a big portion of the overall error of machined parts need more attention in precision of components produced by using CNC machine tools. As a result, it is essential to simulate and compensate the errors in the machined components in order to increase accuracy of machined parts. In order to simulate and analyze the real manufactured components in virtual environments, virtual machining systems are proposed. In this paper, application of virtual machining system is investigated in order to simulate and compensate dimensional, geometrical, thermal and tool deflection errors in 5-axis milling operations of free form surfaces. The volumetric error vectors regarding the dimensional, geometrical, thermal and tool deflection errors at each cutting tool location throughout the machining pathways are calculated and compensated utilizing the study's created virtual machining technology. In order to validate the study, a sample workpiece with free from surfaces is milled by using the 5-axis CNC machine tool. The machine part is then measure by suing the CMM machine in order to obtain the dimensional, geometrical, thermal and tool deflection errors during milling operations of free form surfaces. Thermal sensors are also installed to the different locations of CNC machine tool in order to measure the thermal error of CNC machine tool during machining operations. Finally, in order to improve accuracy in 5-axis milling operations of free form surfaces, new cutting tool paths regarding the compensated volumetric errors of dimensional, geometrical, thermal, and tool deflection errors are generated. As a result, by utilizing the proposed virtual machining system in the research work, precision as well as reliability during 5-axis milling operations of free form surfaces can be enhanced. 1-Introduction 5-Axic CNC machine tools are utilized in machining operations of complex parts with free form surfaces such as turbine blades, airplane parts, dies and molds. Machining operations of free form surfaces using 5 axis CNC machine tools are always with complexities and challenges which is analyzed in order to be modified in numerous research works. There are errors and inaccuracies in CNC machining operations which can decrease quality and reliabilities of machined parts using CNC machine tools. The errors are due to geometrical deviation of machine tools, cutting force

description: The First G-APD Cherenkov Telescope (FACT) is the first in-operation test of the performance of silicon photo detectors in Cherenkov Astronomy. For more than two years it is operated on La Palma, Canary Islands (Spain), for the purpose of long-term monitoring of astrophysical sources. For this, the performance of the photo detectors is crucial and therefore has been studied in great detail. Special care has been taken for their temperature and voltage dependence implementing a correction method to keep their properties stable. Several measurements have been carried out to monitor the performance. The measurements and their results are shown, demonstrating the stability of the gain below the percent level. The resulting stability of the whole system is discussed, nicely demonstrating that silicon photo detectors are perfectly suited for the usage in Cherenkov telescopes, especially for long-term monitoring purpose.

description: For a generalized super KdV equation, three Darboux transformations and the corresponding Bäcklund transformations are constructed. The compatibility of these Darboux transformations leads to three discrete systems and their Lax representations. The reduction of one of the Bäcklund-Darboux transformations and the corresponding discrete system are considered for Kupershmidt's super KdV equation. When all the odd variables vanish, a nonlinear superposition formula is obtained for Levi's Bäcklund transformation for the KdV equation.

This study examines the relationship between the sustainability of financial technology (FinTech) and financial fraud deterrence. FinTech has chance to promote sustainable finance and condense financial fraud, which ultimately contributes to the financial system's integrity. Many reports and other sources of information regarding financial service providers and regulators in the FinTech industry were utilized to collect the secondary data. FinTech can improve the sustainability of economic systems and reduce the incidence of fraud by providing advanced security features as well as effective payment systems, according to the outcomes of the study. FinTech may improve financial transaction transparency, accountability, and ecological sustainability. In addition, the study demonstrates that regulatory organizations play a crucial role in promoting the viability of FinTech and preventing financial fraud. The study suggests that sources of financial services ought to develop FinTech solutions that incorporate advanced security features, efficient payment systems, transparency, and environmental sustainability. In addition, regulatory agencies should provide a robust legal and regulatory structure to promote the sustainability of FinTech. Additionally, consumers should be offered education and awareness programs regarding FinTech sustainability and fraud prevention. The key finding of the study is that FinTech has the potential to completely transform the financial system by increasing sustainability and decreasing fraud. However, stakeholders in the FinTech industry must collaborate to surmount the challenges and capitalize on all the possibilities that FinTech presents.
