description: We investigate a stochastic search process in one dimension under the competing roles of mortality, redundancy, and diversity of the searchers. This picture represents a toy model for the fertilization of an oocyte by sperm. A population of $N$ independent and mortal diffusing searchers all start at $x=L$ and attempt to reach the target at $x=0$. When mortality is irrelevant, the search time scales as $τ_D/\ln N$ for $\ln N\gg 1$, where $τ_D\sim L^2/D$ is the diffusive time scale. Conversely, when the mortality rate $μ$ of the searchers is sufficiently large, the search time scales as $\sqrt{τ_D/μ}$, independent of $N$. When searchers have distinct and high mortalities, a subpopulation with a non-trivial optimal diffusivity are most likely to reach the target. We also discuss the effect of chemotaxis on the search time and its fluctuations.

description: The Education domain of the social determinants of health (SDOH) impacts length of life and general health over an individual’s lifetime (Healthy People 2030). Early childhood reading proficiency is an aspect of education in the public school system that can influence the academic, emotional, and social wellbeing of children (Reading Foundation, 2023). In Durham County, North Carolina, the reading proficiency test scores for elementary students are lower than that for the state of North Carolina, with a further disparity observed in Black and Hispanic students compared to white students in Durham Public Schools (Durham Public Schools, 2023). Nutrition status is an indicator of a child’s overall health, which is associated with their attentiveness and receptiveness to school lessons (Cadiz-Gabjan & Quirino, 2021). Dietary habits formed in childhood influence the habits continued into adulthood, which consequently influences overall health (Chaudhary et al., 2020). Poor nutrition will also negatively influence school attendance, which leads to decreased academic performance (Virginia Commonwealth, 2015). This proposal aims to create a program designed for Durham County Public Schools integrating various school subjects into hands-on nutrition lessons aiming to increase attendance rates and standardized test scores in mathematics, reading, and science among Black and Hispanic students in Durham Public Schools.

description: We propose two strategies to improve economic stability as a social determinant of health by improving the accessibility of early childhood education in Durham County. The first strategy would create a Spanish-speaking teacher development program to address the lack of adequate teacher support for Spanish-speaking dual-language learners in Durham PreK classrooms. The program will provide entry-level Durham PreK teachers with training and peer support to advance in the early childhood education workforce. The second strategy is to deliver biweekly nutritious family-sized meals for 36 weeks and provide a standard cookware set for low-income families who qualify for Head Start and Early Head Start services. The meals will be prepared through a partnership with Meals on Wheels and supplemented with commercial delivery services. Community partners would include low-income families in Durham County and Durham PreK. We urge the Durham County Commissioners to carefully consider these evidence-based strategies for local implementation.
Rashba coupling and magnetic order in correlated helical liquids

description: We study strongly correlated helical liquids with and without Rashba coupling using quantum Monte Carlo simulations of the Kane-Mele model with a Hubbard interaction at the edge. Independent of the Rashba coupling, we find that interactions enhance spin correlations and suppress the spectral weight at the Fermi level. For sufficiently strong interactions, a gap can be observed in the single-particle spectral function. However, based on a finite-size scaling analysis and theoretical arguments, we argue that this gap is closed by order parameter fluctuations in the Luttinger liquid phase even at zero temperature, and filled in by thermally induced kinks in the order parameter in the Mott phase at finite temperatures. While the bosonization suggests an umklapp-driven Mott transition only in the presence of Rashba coupling and hence a significant impact of the latter, our numerical results are almost unaffected by Rashba coupling even at low temperatures.

description: The hunter-gatherer groups represent the oldest and perhaps most successful human adaptation on this planet. Until 12,000 years ago, before the starting of cultivation system in the Fertile Crescent, virtually all humanity lived as hunters and gatherers. Therefore, investigations on present day hunter-gatherer societies may hold the key to some of the central questions about humans’life in nature before urbanization. Moreover, they may hold information about the processes which shifted people from their natural habitat. The Munda people of Palkichara village are still observed to be unique with their ancestral way of life despite of being socio-economically controlled by the local tea estate. Hunting and gathering are the two main ways of subsistence which reflect in their every aspects of family, social and cultural practices. Therefore, being completely attached with nature and almost untouched by rest of the world, the Munda people of Palkichara village may provide some pictures of prehistoric hunter gatherer societies. This study is aimed to focus on some significant aspects of the traditional hunting-gathering methods and techniques as well as the questions on how and why the primitive way of life is still active in Munda tribal people of Palkichara village.

description: In the world of extreme media consumption and a plethora of messages being directed at every internet user, new media literacy is arguably an important skill for any consumer to possess. This honors thesis seeks to examine the relationship between new media literacy and students’ critical consumption of health and wellness content on the popular social media platform TikTok. Through survey research, the relationship between students’ levels of new media literacy and their perception of credibility of content pulled from TikTok was examined. The research found that the NML scale used may not valid for use in the United States and that further analysis should be conducted to help further research in this relevant field of study.

description: Magnetic refrigeration based on the magnetocaloric effect (MCE) of materials is a potential technique that has prominet advantages over the currently used gas compression-expansion technique in the sense of its high efficiency and environment friendship. In this article, our recent progress in explorating effective MCE materials is reviewed with the emphasis on the MCE in the LaFe13-xSix-based alloys with a first order magnetic transition discovered by us. These alloys show large entropy changes in a wide temperature range near room temperature. Effects of magnetic rare-earth doping, interstitial atom, and high pressure on the MCE have been systematically studied. Special issues such as appropriate approaches to determining the MCE associated with the first-order magnetic transition, the depression of magnetic and thermal hystereses, and the key factors determining the magnetic exchange in alloys of this kind are discussed. The applicability of the giant MCE materials to the magnetic refrigeration near ambient temperature is evaluated. A brief review of other materials with significant MCE is also presented in the article.

description: The Read and Feed program in Durham County aims to increase the health literacy of elementary public-school students of low socioeconomic status. The program addresses disparities in the county by focusing on two short-term outcomes: improving reading attitude or confidence and serving at least 600 meals to participating children. The program will provide health literacy education through books, along with a nutritious meal at each session. Community partners, including parents, Durham Public Schools, Durham’s Partnership for Children, and the Durham County Commissioners, will play a key role in supporting the program. This program recommendation is to establish a health literacy program based on Wake County’s Read and Feed program for Durham County School’s elementary school students who have low SES. The program will teach nutrition, improve overall reading skills, and provide further reading opportunities, with all books on health and well-being topics. The program is aimed at increasing health literacy and promoting equity through the accessible provision of books with health topics and nutritional meals to children with low socioeconomic status (SES).

description: In the extreme high intensity regime of electromagnetic (EM) waves in plasma, the acceleration process is found to be dominated by the ponderomotive acceleration (PA). While the wakefields driven by the ponderomotive force of the relativistic intensity EM waves are important, they may be overtaken by the PA itself in the extreme high intensity regime when the dimensionless vector potential $a_0$ of the EM waves far exceeds unity. The energy gain by this regime (in 1D) is shown to be (approximately) proportional to $a_0^2$. Before reaching this extreme regime, the coexistence of the PA and the wakefield acceleration (WA) is observed where the wave structures driven by the wakefields show the phenomenon of multiple and folded wave-breakings. Investigated are various signatures of the acceleration processes such as the dependence on the mass ratio for the energy gain as well as the energy spectral features. The relevance to high energy cosmic ray acceleration and to the relativistic laser acceleration is considered.

description: Economic stability is a social determinant of health that impacts a wide range of health risks and outcomes through the environment in which people are born, live, learn, and work. A lack of affordable housing as a factor contributing to economic instability forces many Durham County residents to spend a large portion of their income on rent, leaving many people in poverty. Having fewer economic resources prevents people from affording healthy food and preventative healthcare and puts them at greater risk of chronic conditions and premature mortality. The proposed program and policy aim to prevent Durham County residents from making trade-offs between affording housing and obtaining nutritious food. The program will partner with the Inter-Faith Food Shuttle to expand their mobile market model to the McDougald Terrace public housing community, and the policy will expand the Durham Community Land Trust (DCLT) with permanent municipal funding in the Durham County budget.

description: The low energy spectrum of a spin chain with $OSp(3|2)$ supergroup symmetry is studied based on the Bethe ansatz solution of the related vertex model. This model is a lattice realization of intersecting loops in two dimensions with loop fugacity $z=1$ which provides a framework to study the critical properties of the unusual low temperature Goldstone phase of the $O(N)$ sigma model for $N=1$ in the context of an integrable model. Our finite-size analysis provides strong evidence for the existence of continua of scaling dimensions, the lowest of them starting at the ground state. Based on our data we conjecture that the so-called watermelon correlation functions decay logarithmically with exponents related to the quadratic Casimir operator of $OSp(3|2)$. The presence of a continuous spectrum is not affected by a change to the boundary conditions although the density of states in the continua appears to be modified.

Publisher: name: arXiv

description: The article is devoted to the developement of the method of expansion and mean-square approximation of iterated Ito stochastic integrals based on generalized multiple Fourier series converging in the sense of norm in the space $L_2([t, T]^k)$ ($k$ is the multiplicity of the iterated Ito stochastic integral). We obtain the exact and approximate expressions for the mean-square approximation error of iterated Ito stochastic integrals of multiplicity $k$ ($k\in\mathbb{N}$) from the stochastic Taylor-Ito expansion. As a result, we do not need to use redundant terms of expansions of iterated Ito stochastic integrals that complicate the numerical methods for Ito stochastic differential equations. Moreover, we proved the convergence with propability 1 for the method of expansion of iterated Ito stochastic integrals based on generalized multiple Fourier series for the cases of multiple Fourier-Legendre series and multiple trigonometric Fourier series. Mean-square approximation of iterated Stratonovich stochastic integrals is also considered in the article. The results of the article can be applied to the high-order strong numerical methods for Ito stochastic differential equations as well as for non-commutative semilinear stochastic partial differential equations with multiplicative trace class noise.

description: In several smart city applications, multiple resources must be allocated among competing agents that are coupled through such shared resources and are constrained --- either through limitations of communication infrastructure or privacy considerations. We propose a distributed algorithm to solve such distributed multi-resource allocation problems with no direct inter-agent communication. We do so by extending a recently introduced additive-increase multiplicative-decrease (AIMD) algorithm, which only uses very little communication between the system and agents. Namely, a control unit broadcasts a one-bit signal to agents whenever one of the allocated resources exceeds capacity. Agents then respond to this signal in a probabilistic manner. In the proposed algorithm, each agent makes decision of its resource demand locally and an agent is unaware of the resource allocation of other agents. In empirical results, we observe that the average allocations converge over time to optimal allocations.

description: An intelligent optical performance monitor using multi-task learning based artificial neural network (MTL-ANN) is designed for simultaneous OSNR monitoring and modulation format identification (MFI). Signals' amplitude histograms (AHs) after constant module algorithm are selected as the input features for MTL-ANN. The experimental results of 20-Gbaud NRZ-OOK, PAM4 and PAM8 signals demonstrate that MTL-ANN could achieve OSNR monitoring and MFI simultaneously with higher accuracy and stability compared with single-task learning based ANNs (STL-ANNs). The results show an MFI accuracy of 100% and OSNR monitoring root-mean-square error of 0.63 dB for the three modulation formats under consideration. Furthermore, the number of neuron needed for the single MTL-ANN is almost the half of STL-ANN, which enables reduced-complexity optical performance monitoring devices for real-time performance monitoring.

The article considers innovative technologies in professional education from the point of view of their definitions, essence, forms, and influence on the competence of future specialists in economic disciplines. The importance of the discipline “Finance and credit” is noted both for students in the system of professional education, and for everyone who faces issues of financing and lending in everyday life. As a didactic tool that contributes to the individualization of training, a workbook on the discipline “Finance and credit” is offered. In this regard, the application issues of innovative educational technologies in the teaching of economic disciplines are relevant.

description: Internet-of-Things (IoT) enables the development of sharing economy applications. In many sharing economy scenarios, agents both produce as well as consume a resource; we call them prosumers. A community of prosumers agrees to sell excess resource to another community in a prosumer market. In this chapter, we propose a control theoretic approach to regulate the number of prosumers in a prosumer community, where each prosumer has a cost function that is coupled through its time-averaged production and consumption of the resource. Furthermore, each prosumer runs its distributed algorithm and takes only binary decisions in a probabilistic way, whether to produce one unit of the resource or not and to consume one unit of the resource or not. In the proposed approach, prosumers do not explicitly exchange information with each other due to privacy reasons, but little exchange of information is required for feedback signals, broadcast by a central agency. In the proposed approach, prosumers achieve the optimal values asymptotically. Furthermore, the proposed approach is suitable to implement in an IoT context with minimal demands on infrastructure. We describe two use cases; community-based car sharing and collaborative energy storage for prosumer markets. We also present simulation results to check the efficacy of the algorithms.

description: Bent-tailed (BT) radio sources have long been known to trace over densities in the Universe up to z ~ 1 and there is increasing evidence this association persists out to redshifts of 2. The morphology of the jets in BT galaxies is primarily a function of the environment that they have resided in and so BTs provide invaluable clues as to their local conditions. Thus, not only can samples of BT galaxies be used as signposts of large-scale structure, but are also valuable for obtaining a statistical measurement of properties of the intra-cluster medium including the presence of cluster accretion shocks & winds, and as historical anemometers, preserving the dynamical history of their surroundings in their jets. We discuss the use of BTs to unveil large-scale structure and provide an example in which a BT was used to unlock the dynamical history of its host cluster. In addition to their use as density and dynamical indicators, BTs are useful probes of the magnetic field on their environment on scales which are inaccessible to other methods. Here we discuss a novel way in which a particular sub-class of BTs, the so-called `corkscrew' galaxies might further elucidate the coherence lengths of the magnetic fields in their vicinity. Given that BTs are estimated to make up a large population in next generation surveys we posit that the use of jets in this way could provide a unique source of environmental information for clusters and groups up to z = 2.

description: We describe the main ingredients needed to create, from the smooth lagrangian density, a variational principle for discrete motions of a discrete rod, with corresponding conserved Noether currents. We describe all geometrical objects in terms of elements on the linear Atiyah bundle, using a reduced forward difference operator. We show how this introduces a discrete lagrangian density that models the discrete dynamics of a discrete rod. The presented tools are general enough to represent a discretization of any variational theory in principal bundles, and its simplicity allows to perform an iterative integration algorithm to compute the discrete rod evolution in time, starting from any predefined configurations of all discrete rod elements at initial times.

By analyzing the full Kepler dataset and 34 Keck/HIRES radial velocity observations, we measure both the observed transit depth and Doppler semiamplitude to 0.5% precision. With Robo-AO and Palomar/PHARO adaptive optics imaging as well as TripleSpec spectroscopy, we measure a model-dependent mass for LHS 6343 C of 62.1 +/- 1.2 M_Jup and a radius of 0.783 +/- 0.011 R_Jup. We detect the secondary eclipse in the Kepler data at 3.5 sigma, measuring e cos omega = 0.0228 +/- 0.0008. We also derive a method to measure the mass and radius of a star and transiting companion directly, without any reliance on stellar models. The mass and radius of both objects depend only on the orbital period, stellar density, reduced semimajor axis, Doppler semiamplitude, eccentricity, and inclination, as well as the knowledge that the primary star falls on the main sequence. With this method, we calculate a model-independent mass and radius for LHS 6343 C to a precision of 3% and 2%, respectively.

description: We give a twistorial interpretation of geometric structures on a Riemannian manifold, as sections of homogeneous fibre bundles, following an original insight by Wood (2003). The natural Dirichlet energy induces an abstract harmonicity condition, which gives rise to a geometric gradient flow. We establish a number of analytic properties for this flow, such as uniqueness, smoothness, short-time existence, and some sufficient conditions for long-time existence. This description potentially subsumes a large class of geometric PDE problems from different contexts. As applications, we recover and unify a number of results in the literature: for the isometric flow of ${\rm G}_2$-structures, by Grigorian (2017, 2019), Bagaglini (2019), and Dwivedi-Gianniotis-Karigiannis (2019); and for harmonic almost complex structures, by He (2019) and He-Li (2019). Our theory also establishes original properties regarding harmonic flows of parallelisms and almost contact structures.

1D accretion discs around eccentric planets: observable near-infrared variability
Creators: name: Dunhill, Alex
Publisher: name: arXiv
Year: 2014
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: I present the results of 1D models of circumplanetary discs around planets on eccentric orbits. I use a classical viscous heating model to calculate emission fluxes at the wavelengths targeted by the NIRCam instrument on JWST, and compare the variability of this signal with the published NIRCam sensitivity specifications. This variability is theoretically detectable by JWST for a sufficiently viscous disc ($α\sim 10^{-2}$) around a sufficiently eccentric planet ($e \sim 0.1-0.2$) and if the circumplanetary disc accretes material from its parent disc at a rate $\dot{M} \gtrsim 10^{-7}\, \mathrm{M}_{\odot}\,\mathrm{yr}^{-1}$. I discuss the limitations of the models used, and the implications of the result for probing the effectiveness of disc interactions for growing a planet's orbital eccentricity.

description: We investigate the effect of non-paraxiality in the dynamics of dispersive shock waves in the defocusing nonlinear Schroedinger equation. We show that the problem can be described in terms of a relativistic particle moving in a potential. Lowest order corrections enhance the wave-breaking and impose a limit to the highest achievable spectrum in an amount experimentally testable.

description: To better address the broad spectrum of health in Durham County, North Carolina, this capstone offers a series of housing and nutritional policy reforms that aim to improve the economic security of Durham County residents by addressing the bidirectional nature of housing and food insecurity. The following proposal explains the impact economic precarity and instability has on Durham County residents’ health and how it impacts how residents live, work, and play. The proposal details how reforming zoning laws for affordable housing, coupled with community gardens and nutrition education can help improve economic security for Durham County residents and how such policies will improve the County’s public health. These proposals also include a detailed budget its zoning reform policy and program evaluation for its community gardens program. The proposal also includes an appendix with an additional housing reform policy to build additional permanent low-income housing.

description: Observations with the Fermi Large Area Telescope (LAT) indicate an excess in gamma rays originating from the center of our Galaxy. A possible explanation for this excess is the annihilation of Dark Matter particles. We have investigated the annihilation of neutralinos as Dark Matter candidates within the phenomenological Minimal Supersymmetric Standard Model (pMSSM). An iterative particle filter approach was used to search for solutions within the pMSSM. We found solutions that are consistent with astroparticle physics and collider experiments, and provide a fit to the energy spectrum of the excess. The neutralino is a Bino/Higgsino or Bino/Wino/Higgsino mixture with a mass in the range $84-92$~GeV or $87-97$~GeV annihilating into W bosons. A third solutions is found for a neutralino of mass $174-187$~GeV annihilating into top quarks. The best solutions yield a Dark Matter relic density $0.06 < Ωh^2 <0.13$. These pMSSM solutions make clear forecasts for LHC, direct and indirect DM detection experiments. If the MSSM explanation of the excess seen by Fermi-LAT is correct, a DM signal might be discovered soon.

Near Infrared Spectroscopy of M Dwarfs. II. H2O Molecule as an Abundance Indicator of Oxygen

description: Based on the near infrared spectra (R~20000) of M dwarfs, oxygen abundances are determined from the ro-vibrational lines of H2O. Although H2O lines in M dwarfs are badly blended each other and the continuum levels are depressed appreciably by the collective effect of numerous H2O lines themselves, quantitative analysis of H2O lines has been carried out by referring to the pseudo-continua both on the observed and theoretical spectra. For this purpose, the pseudo-continuum on the theoretical spectrum has been evaluated by the use of the recent high-precision H2O line-list. Then, we propose a simple and flexible method of analyzing equivalent widths (EWs) of blended features by the use of a mini curve-of-growth (CG), which is a small portion of the usual CG around the observed EW. The mini CG is generated by using the theoretical EWs evaluated from the synthetic spectrum by exactly the same way as the EWs are measured from the observed spectrum. The observed EW is converted to the abundance by the use of the mini CG, and the process is repeated for all the observed EWs line-by-line or blend-by-blend. In cool M dwarfs, almost all the oxygen atoms left after CO formation are in stable H2O molecules, which suffer little change for the uncertainties due to imperfect modelling of the photospheres. Then the numerous H2O lines are excellent abundance indicators of oxygen. The oxygen abundances are determined to be logAo between -3.5 and -3.0 in 38 M dwarfs. The resulting O/C ratios plotted against logAc appear to be systematically smaller in the carbon-rich M dwarfs, showing the different formation histories of oxygen and carbon in the chemical evolution of the Galactic disk. Also, O/Fe ratios in most M dwarfs are closer to the solar O/Fe ratio based on the classical high oxygen abundance rather than on the recently downward revised low value.

Research on the Trend and Influencing Factors of Residential Property Sales Prices in Charlotte City, North Carolina
Creators: name: Wang, Jiayin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2023

description: This study mainly focuses on the changing trend of residential properties value in and around Charlotte City, North Carolina from 2000 to 2020. We selected a local repeated sales record database and screened it, ultimately retaining 492,888 valid results. By spatially joining it with the Block Groups map of Mecklenburg County, we obtained the average sales price data for each block over 20 years (adjusted for inflation). We used two methods for processing advanced calculations. The YoY Growth Rate method is mainly used to reflect the changes in the overall price growth rate between different regions, while the Average Increment Accumulation method is used to visualize data in geospatial view, and its distribution trend is more obvious.
