The Causal Impact of Educational Attainment on Self-Rated Health
Creators: name: Emch, Sadie
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: There are growing health disparities across educational levels among young and middle-aged adults in the United States; however, it is not clear whether there is a causal relationship between educational attainment and health. This study examines this relationship by determining the causal impact of educational attainment on self-rated health in the United States and estimates whether this relationship is different for population subgroups, i.e., White women, White men, 
Black women and Black men. We use data on 17,643 individuals from five waves (1994–2018) of the National Longitudinal Study of Adolescent to Adult Health (Add Health). Self-rated health 
is measured on a 1 to 5 scale from excellent to poor health. Educational attainment is measured both as a continuous variable of years of education and as credential milestones (e.g., high school, college, graduate degree). The functional form that best describes the relationship between educational attainment and self-rated health is determined by assessing model fit using Bayesian Information Criterion (BIC). Correlated random effects regression is used to estimate 
the impact of educational attainment on self-rated health using the optimal functional form for educational attainment for each population subgroup. The findings show that educational attainment improves self-rated health; however, the effect size is reduced by the correction for 
endogeneity. A combination of educational milestones and benefits from each additional year of education best fit the total sample, White men, and White women, while a solely continuous education model is the best fit for both Black men and Black women. More specifically, 
credentials are particularly important for White women and continuous education for White men. This study shows that health and education policy are connected and should include the goal of having students reach educational milestones as well as keep students in school for as long as possible in order to improve their health across the life course.

description: In this review, we discuss a relation between quantum communication complexity and a long-standing debate in quantum foundation concerning the interpretation of the quantum state. Is the quantum state a physical element of reality as originally interpreted by Schrodinger? Or is it an abstract mathematical object containing statistical information about the outcome of measurements as interpreted by Born? Although these questions sound philosophical and pointless, they can be made precise in the framework of what we call classical theories of quantum processes, which are a reword of quantum phenomena in the language of classical probability theory. In 2012, Pusey, Barrett and Rudolph (PBR) proved, under an assumption of preparation independence, a theorem supporting the original interpretation of Schrodinger in the classical framework. Recently, we showed that these questions are related to a practical problem in quantum communication complexity, namely, quantifying the minimal amount of classical communication required in the classical simulation of a two-party quantum communication process. In particular, we argued that the statement of the PBR theorem can be proved if the classical communication cost of simulating the communication of n qubits grows more than exponentially in 'n'. Our argument is based on an assumption that we call probability equipartition property. This property is somehow weaker than the preparation independence property used in the PBR theorem, as the former can be justified by the latter and the asymptotic equipartition property of independent stochastic sources. The equipartition property is a general and natural hypothesis that can be assumed even if the preparation independence hypothesis is dropped. In this review, we further develop our argument into the form of a theorem.
Bioinspired Navigation Based on Distributed Sensing in the Leech using Dynamic Neural Fields

description: Leeches use various sensory stimuli to navigate around their environment and perform survival behaviors. Water wave disturbances serve as an important source of environmental information for aquatic animals as they can be the distinguishing factor between a predator or prey. Previous studies show that certain leech species prefer specific frequencies of water waves, suggesting that the leech’s sensory receptors have been evolutionarily calibrated to respond to wave frequencies in the safest way. While these animal studies provide important discoveries about the relationship between sensory information and animal behavior, the internal neural mechanisms driving the leech’s decision-making are still unknown. In this study, we present a model that mimics the navigational behavior of the leech using dynamic neural fields and an agent-based simulation. The modeled leech (agent) was placed in virtual environments containing simulated stimuli based on the actual stimuli a leech detects in their natural environment. Sensors placed around the agent detected the stimulus and sent the sensory information to a neural field, which was responsible for calculating navigational behaviors. Data produced by the model matched real-world observed behaviors found in previous leech studies. The development and validation of this model offer a fast and low-cost way to study leech behavior, compliment animal experiments, and provide insights into the mechanics behind distributed sensing in animals. Additionally, the findings may provide insights into novel data-processing methods and architectures for man-made sensory systems that rely on multiple sensors.

Conservation laws and laser cooling of atoms

description: The straightforward application of energy and linear momentum conservation to the absorption/emission of photons by atoms allows to establish the essential features of laser cooling of two levels atoms at low laser intensities. The lowest attainable average kinetic energy of the atoms depends on the ratio $Γ/E_R$ between the natural linewidth and the recoil energy and tends to $E_R$ as $Γ$ tends to zero. This treatment, as the quantum mechanical ones, is valid for any value of the ratio $Γ/E_R$ and contains the semiclassical theory of laser cooling as the limiting case in which $E_R\ll Γ$.
description: The dimensionless parameter $B_D$ have been redefinied as $\Gamma/\Delta E_M$ (instead of $\Gamma/2\Delta E_M$) in order to avoid a factor of two when compared with a similar parameter used in literature. Consequently, some equations have been rewritten and some figures modified accordingly. Of Course, the physics does not change. Some minor changes aimed at improving the clarity of the text

description: It is a well-established fact that intranuclear-cascade models generally fail to consistently reproduce the cross sections for one-proton and one-neutron removal from stable nuclei by a high-energy proton beam. We use simple shell-model calculations to investigate the reasons of this deficiency. We find that a refined description of the neutron skin and of the energy density in the nuclear surface is crucial for the aforementioned observables, and that neither ingredient is sufficient if taken separately. As a by-product, the predictions for removal of several nucleons are also improved by the refined treatment.

description: Since the preparation of labeled data for training semantic segmentation networks of point clouds is a time-consuming process, weakly supervised approaches have been introduced to learn from only a small fraction of data. These methods are typically based on learning with contrastive losses while automatically deriving per-point pseudo-labels from a sparse set of user-annotated labels. In this paper, our key observation is that the selection of what samples to annotate is as important as how these samples are used for training. Thus, we introduce a method for weakly supervised segmentation of 3D scenes that combines self-training with active learning. The active learning selects points for annotation that likely result in performance improvements to the trained model, while the self-training makes efficient use of the user-provided labels for learning the model. We demonstrate that our approach leads to an effective method that provides improvements in scene segmentation over previous works and baselines, while requiring only a small number of user annotations.

description: Nanowire double quantum dots occupied by an even number of electrons are investigated in the context of energy level structure revealed by electric dipole spin resonance measurements. We use numerically exact configuration interaction approach up to 6 electrons for systems tuned to Pauli spin blockade regime. We point out the differences between the spectra of systems with two and a greater number of electrons. For two-electrons the unequal length of the dots results in a different effective $g$-factors in the dots as observed by the recent experiments. For an increased number of electrons the $g$-factor difference between the dots appears already for symmetric systems and it is greatly amplified when the dots are of unequal length. We find that in the lowest energy states all except of two electrons form a frozen core of singlet shells that can be separated away for description of the properties of the system.
Piedmont Health COVID-19 Task Order Response Evaluation
Creators: name: Liborio, Julia
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Objectives: North Carolina COVID-19 task orders were designed to increase statewide testing access. This study explored how CHAMP and OP-9 task orders issued by NC Department of Health and Human Services (DHHS) and the Community Health Center (CHC) Association influenced Piedmont Health Services’ (PHS) COVID-19 testing target populations, location priorities, and patient services.

Methods: The researcher conducted a quantitative secondary data analysis using descriptive statistics and a time series evaluation. This assessed how PHS’s target populations, location priorities, and patient services were influenced by task order implementation. This analysis utilized COVID-19 testing administration data to determine how each task order influenced these elements of COVID-19 testing access at PHS during specified task order implementation stages. 

Findings: This study found that the implementation of CHAMP and OP-9 task orders influenced PHS to improve COVID-19 testing access to Black and Latinx populations and more rural areas of North Carolina. Most findings also suggest a major influence from both task orders on PHS’s fulfillment of required patient services, including collecting race and ethnicity data, providing linguistically appropriate services, and connecting patients to a primary care provider.

Implications: This research has concluded that both task orders have influenced COVID-19 testing accessibility at PHS. These findings could be applicable to additional CHCs across North Carolina and other states. Future studies should examine the collective impact of task orders on multiple CHCs in order to analyze their effect on health care accessibility on a larger scale.

description: We investigate the electronic structure of (Sr$_{1-x}$La$_x$)$_2$RhO$_4$ using a combination of the density functional and dynamical mean-field theories. Unlike the earlier local density approximation plus Hubbard $U$ (LDA+U) studies, we find no sizable enhancement of the spin-orbit splitting due to electronic correlations and show that such an enhancement is a spurious effect of the static mean-field approximation of the LDA+U method. The electron doping suppresses the importance of electronic correlations, which is reflected in quasi-particle bandwidth increasing with $x$. (Sr$_{1-x}$La$_x$)$_2$RhO$_4$ can be classified as weakly correlated metal, which becomes an itinerant in-plane ferromagnet (but possibly A-type antiferromagnet) due to Stoner instability around $x=0.2$.

description: In observational astronomy, noise obscures signals of interest. Large-scale astronomical surveys are growing in size and complexity, which will produce more data and increase the workload of data processing. Developing automated tools, such as convolutional neural networks (CNN), for denoising has become a promising area of research. We investigate the feasibility of CNN-based self-supervised learning algorithms (e.g., Noise2Noise) for denoising astronomical images. We experimented with Noise2Noise on simulated noisy astronomical data. We evaluate the results based on the accuracy of recovering flux and morphology. This algorithm can well recover the flux for Poisson noise ( $98.13${\raisebox{0.5ex}{\tiny$^{+0.77}_{-0.90} $}$\large\%$}) and for Gaussian noise when image data has a smooth signal profile ($96.45${\raisebox{0.5ex}{\tiny$^{+0.80}_{-0.96} $}$\large\%$}).

description: We investigated the strange hadrons transverse momentum ($p_T$) spectra in Au-Au collision at $\sqrt {s_{NN}}$ = 54.4 GeV in the framework of modified Hagedorn function with embedded flow. We extracted the kinetic freeze-out temperature $T_0$, transverse flow velocity $β_T$, kinetic freeze-out volume $V$, mean transverse momentum $$, the entropy parameter $n$ and the multiplicity parameter $N_0$. We reported that all these parameters increase towards the central collisions. The larger kinetic freeze-out temperature , transverse flow velocity, kinetic freeze-out volume and the entropy parameter (n) in central collisions compared to peripheral collisions show the early decoupling of the particles in central collisions. In addition, all the above parameters are mass dependent. The kinetic freeze-out temperature ($T_0$), the entropy parameter $n$ and mean transverse momentum ($$) are larger for massive particles, while the transverse flow velocity ($β_T$), kinetic freeze-out volume ($V$) and the multiplicity parameter ($N_0$) show the opposite behavior. Larger $T_0$, $n$ and smaller $β_T$ as well as $V$ of the heavier particles indicates the early freeze-out of the heavier particles, while larger $$ for the heavier particles evince that the effect of radial flow is stronger in heavier particles. The separate set of parameters for each particle shows the multiple kinetic freeze-out scenario, where the mass dependent kinetic freeze-out volume shows the volume differential freeze-out scenario. We also checked the correlation among different parameters, which include the correlation of $T_0$ and $β_T$, $T_0$ and $V$, $β_T$ and $V$, $$ and $T_0$, $$ and $β_T$, $$ and $V$, $n$ and $T_0$, $n$ and $β_T$, and $n$ and $V$, and they all are observed to have positive correlations with each other which validates our results.

description: Study Objective: This study evaluated the virtual implementation of the Child-Adult Relationship in Primary Care (PriCARE) Parenting Program after it shifted online due to the COVID-19 pandemic. Specifically, acceptability, feasibility, and appropriateness of the virtual implementation were studied. 

Intervention: PriCARE is a positive parenting program that is six weeks long and delivered in pediatric primary care clinics by mental health professionals for parents of preschool-aged children.

Methods: This was a mixed methods study consisting of a quantitative survey and a qualitative interview. It involved primary data collection from a study sample of trainers who facilitated and caregivers who attended virtual PriCARE. Quantitative data analysis included descriptive statistics and qualitative data analysis included qualitative coding of themes relating to barriers and facilitators of participation and engagement in the virtual format.

Findings: The final study sample was 8 (4 trainers and 4 caregivers). Both groups found the intervention appropriate, feasible, and acceptable as they had high and consistent scores on both implementation and telehealth usability measures. The largest barrier was the lack of interaction and the largest facilitator was accessibility.

Conclusions: This study concluded that the virtual implementation of PriCARE was acceptable, feasible, and appropriate for both trainers and caregivers. This study provides support for virtual PriCARE sessions to continue with this format for the remainder of the COVID-19 pandemic at a minimum.

description: Background: While many infectious disease epidemics are initially characterized by an exponential growth in time, we show that district-level Ebola virus disease (EVD) outbreaks in West Africa follow slower polynomial-based growth kinetics over several generations of the disease. Methods: We analyzed epidemic growth patterns at three different spatial scales (regional, national, and subnational) of the Ebola virus disease epidemic in Guinea, Sierra Leone and Liberia by compiling publicly available weekly time series of reported EVD case numbers from the patient database available from the World Health Organization website for the period 05-Jan to 17-Dec 2014. Results: We found significant differences in the growth patterns of EVD cases at the scale of the country, district, and other subnational administrative divisions. The national cumulative curves of EVD cases in Guinea, Sierra Leone, and Liberia show periods of approximate exponential growth. In contrast, local epidemics are asynchronous and exhibit slow growth patterns during 3 or more EVD generations, which can be better approximated by a polynomial than an exponential. Conclusions: The slower than expected growth pattern of local EVD outbreaks could result from a variety of factors, including behavior changes, success of control interventions, or intrinsic features of the disease such as a high level of clustering. Quantifying the contribution of each of these factors could help refine estimates of final epidemic size and the relative impact of different mitigation efforts in current and future EVD outbreaks.

description: We investigate hypothesis testing in nonparametric additive models estimated using simplified smooth backfitting (Huang and Yu, Journal of Computational and Graphical Statistics, \textbf{28(2)}, 386--400, 2019). Simplified smooth backfitting achieves oracle properties under regularity conditions and provides closed-form expressions of the estimators that are useful for deriving asymptotic properties. We develop a generalized likelihood ratio (GLR) and a loss function (LF) based testing framework for inference. Under the null hypothesis, both the GLR and LF tests have asymptotically rescaled chi-squared distributions, and both exhibit the Wilks phenomenon, which means the scaling constants and degrees of freedom are independent of nuisance parameters. These tests are asymptotically optimal in terms of rates of convergence for nonparametric hypothesis testing. Additionally, the bandwidths that are well-suited for model estimation may be useful for testing. We show that in additive models, the LF test is asymptotically more powerful than the GLR test. We use simulations to demonstrate the Wilks phenomenon and the power of these proposed GLR and LF tests, and a real example to illustrate their usefulness.

description: We study, for $SU(2)$ Yang-Mills theories discretized on a lattice, a non-local topological order parameter, the center flux ${z}$. We show that: i) well defined topological sectors classified by $π_1(SO(3))=\mathbb{Z}_2$ can only exist in the ordered phase of ${z}$; ii) depending on the dimension $2 \leq d\leq 4$ and action chosen, the center flux exhibits a critical behaviour sharing striking features with the Kosterlitz-Thouless type of transitions, although belonging to a novel universality class; iii) such critical behaviour does not depend on the temperature $T$. Yang-Mills theories can thus exist in two different continuum phases, characterized by an either topologically ordered or disordered vacuum; this reminds of a quantum phase transition, albeit controlled by the choice of symmetries and not by a physical parameter.

O estudo foi desenvolvido de maneira interdisciplinar , cujas fronteiras disciplinares percorreram o âmbito da filosofia, história e antropologia. Os resultados obtidos a partir das análises de cunho qualitativo e quantitativo, demonstram que o contexto do cemitério não poderia poderia seguir em análise apenas pelo viés das representações sociais em coletividade. Foi considerado que as variações tumulares seriam a materialização das representações do espírito (inconsciente), proporcionando uma espécie de coexistência entre passado e presente, o novo. Os padrões de demarcações dos enterramentos, ou maneiras específicas de organização dos corpos inseridos no espaço do cemitério, foram associados às ações imediatas do consciente em relação ao espaço, o espaço vazio e homogêneo no qual a inteligência humana se realiza. É nele que conseguimos organizar as externas a nós. A extensão dos corpos em relação ao espaço possibilitou compreender que uma das condições do ser-no-mundo- é o ser-no-espaço, representações mútuas do inconsciente e consciente.

Usually in layered superconductors resistivity drops anisotropically. Our analysis also explains that, this behaviour is due to flat or needle shape of the superconducting samples.

description: Nonlinear spatial encoding magnetic (SEM) fields have been studied to complement multichannel RF encoding and accelerate MRI scans. Published schemes include PatLoc, O-Space, Null Space, 4D-RIO, and others, but the large variety of possible approaches to exploiting nonlinear SEMs remains mostly unexplored. Before, we have presented a new approach, Fast ROtary Nonlinear Spatial ACquisition (FRONSAC) imaging, where the nonlinear fields provide a small rotating perturbation to standard linear trajectories. While FRONSAC encoding greatly improves image quality, at the highest accelerations or weakest FRONSAC fields, some undersampling artifacts remain. However, the under-sampling artifacts that occur with FRONSAC encoding are relatively incoherent and well suited to the compressed sensing (CS) reconstruction. CS provides a sparsity-promoting convex strategy to reconstruct images from highly undersampled datasets. The work presented here combines the benefits of FRONSAC and CS. Simulations illustrate that this combination can further improve image reconstruction with FRONSAC gradients of low amplitudes and frequencies.

description: We develop an approach to treat magnetic energy of a ferromagnet for arbitrary curved wires and shells on the assumption that the anisotropy contribution much exceeds the dipolar and other weak interactions. We show that the curvature induces two effective magnetic interactions: effective magnetic anisotropy and effective Dzyaloshinskii-like interaction. We derive an equation of magnetisation dynamics and propose a general static solution for the limit case of strong anisotropy. To illustrate our approach we consider the magnetisation structure in a ring wire and a cone surface: ground states in both systems essentially depend on the curvature excluding strictly tangential solutions even in the case of strong anisotropy. We derive also the spectrum of spin waves in such systems.

description: The size of a data structure (i.e., the number of elements in it) is a widely used property of a data set. However, for concurrent programs, obtaining a correct size efficiently is non-trivial. In fact, the literature does not offer a mechanism to obtain a correct (linearizable) size of a concurrent data set without resorting to inefficient solutions, such as taking a full snapshot of the data structure to count the elements, or acquiring one global lock in all update and size operations. This paper presents a methodology for adding a concurrent linearizable size operation to sets and dictionaries with a relatively low performance overhead. Theoretically, the proposed size operation is wait-free with asymptotic complexity linear in the number of threads (independently of data-structure size). Practically, we evaluated the performance overhead by adding size to various concurrent data structures in Java$-$a skip list, a hash table and a tree. The proposed linearizable size operation executes faster by orders of magnitude compared to the existing option of taking a snapshot, while incurring a throughput loss of $1\%-20\%$ on the original data structure's operations.

description: Context. Many ellipticals are surrounded by round stellar shells probably stemming from minor mergers. A new method for constraining gravitational potential in elliptical galaxies has recently been suggested. It uses the spectral line profiles of these shells to measure the circular velocity at the edge of the shell and the expansion velocity of the shell itself. MOND is an alternative to the dark matter framework aiming to solve the missing mass problem. Aims. We study how the circular and expansion velocities behave in MOND for large shells. Methods. The asymptotic behavior for infinitely large shells is derived analytically. The applicability of the asymptotic results for finitely sized shells is studied numerically on a grid of galaxies modeled with Sérsic spheres. Results. Circular velocity settles asymptotically at a value determined by the baryonic mass of the galaxy forming the baryonic Tully-Fisher relation known for disk galaxies. Shell expansion velocity also becomes asymptotically constant. The expansion velocities of large shells form a multibranched analogy to the baryonic Tully-Fisher relation, together with the galactic baryonic masses. For many - but not all - shell galaxies, the asymptotic values of these two types of velocities are reached under the effective radius. If MOND is assumed to work in ellipticals, then the shell spectra allow many details of the history to be revealed about the formation of the shell system, including its age. The results pertaining to circular velocities apply to all elliptical galaxies, not only those with shells.

description: In tonal languages, the role of intonation in information-structuring has yet to be fully investigated. Intuitively, one would expect intonation to play only a small role in expressing communicative functions. However, experimental studies with Vietnamese native speakers show that intonation contours vary across different contexts and are used to mark certain types of information, for example, focus (Jannedy, 2007). In non-tonal languages (e.g., English), the marking of focus by intonation can influence the processing of focus alternatives (Fraundorf, Watson, & Benjamin, 2010). If Vietnamese also uses intonation to mark focus, the question arises whether the behavioral consequences of prosodic focus marking in Vietnamese are comparable to languages such as English or German. To test this, we replicate a study on memory for focus alternatives, originally carried out in German (Koch & Spalek, in progress), with Vietnamese language stimuli. In the original study, memory for focus alternatives was improved in a delayed recall task for focused elements produced with contrastive intonation in female speakers. Here, we replicate this finding with Northern Vietnamese native speakers: Contrastive intonation seems to improve later recall for focus alternatives in Northern Vietnamese, but only for female participants, in line with the findings by Koch and Spalek (in progress). These results indicate that prosodic focus marking in Vietnamese makes alternatives to the focused element more salient.

The Impact of Intimate Partner Violence on Children's Emotional Development: A Cross-Sectional Analysis in South Africa
Creators: name: Monge, Victoria
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Over recent years, research has focused increasing attention on factors influencing children’s emotional developmental milestones. However, relatively little of this research has focused on children in low and middle-income countries (LMICs), or on the youngest cohorts of children who have not yet reached school age. This secondary data analysis is based on the HPTN 068 HIV prevention study and evaluates the impact of exposure to intimate partner violence (IPV) on Child Behavior Checklist (CBCL) scores for a cohort of children living in the Mpumalanga province of South Africa. Intimate partner violence is measured through a historical variable, in which having ever experienced IPV results in a positive exposure. The data analysis studies the association between a history of IPV and mean CBCL scores, and examines means for the attention and emotional CBCL sub-scores separately utilizing T-tests to analyze differences. We also examined differences across different tertiles of the CBCL scores. The primary results found a slight and statistically insignificant but consistent positive correlation between exposure to intimate partner violence and higher CBCL scores for both the attention and emotional subscores. Furthermore, logistic regressions measuring the effect of IPV on only the highest tertile of CBCL scorers also found a positive correlation, although also statistically insignificant. These results emphasize the importance of identifying and aiding those who may be experiencing intimate partner violence. Moreover, this sheds light on the importance of aiding not only those experiencing intimate partner violence, but also providing resources for children who may be affected. As this is still a relatively new field of research, further studies, particularly in LMICs, will be necessary to confirm and expand upon these results.
Holographic Two-Point Functions in Conformal Gravity

description: In this paper we compute the holographic two-point functions of four dimensional conformal gravity. Precisely we calculate the two-point functions for Energy- Momentum (EM) and Partially Massless Response (PMR) operators that have been identified as two response functions for two independent sources in the dual CFT. The correlation function of EM with PMR tensors turns out to be zero which is expected according to the conformal symmetry. The two-point function of EM is that of a transverse and traceless tensor, and the two-point function of PMR which is a traceless operator contains two distinct parts, one for a transverse-traceless tensor operator and another one for a vector field, both of which fulfill criteria of a CFT. We also discuss about the unitarity of the theory.

Detecting Tripartite Steering via Quantum Entanglement

description: Einstein-Podolsky-Rosen steering is a kind of powerful nonlocal quantum resource in quantum information processing such as quantum cryptography and quantum communication. Many criteria have been proposed in the past few years to detect steerability, both analytically and numerically, for bipartite quantum systems. We propose effective criteria for tripartite steerability and genuine tripartite steerability of three-qubit quantum states by establishing connections between the tripartite steerability (resp. genuine tripartite steerability) and the tripartite entanglement (resp. genuine tripartite entanglement) of certain corresponding quantum states. From these connections, tripartite steerability and genuine tripartite steerability can be detected without using any steering inequalities. The ``complex cost'' of determining tripartite steering and genuine tripartite steering can be reduced by detecting the entanglement of the newly constructed states in the experiment. Detailed examples are given to illustrate the power of our criteria in detecting the (genuine) tripartite steerability of tripartite states.
Allocating New Grantees of the Rural Residency Planning and Development Program: implications for evaluation and policy
Creators: name: Long, Julianna
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Background: Rural-urban disparities in health outcomes and access to care are pervasive. A key solution to these disparities is investment in the rural primary care physician workforce. The Rural Residency Planning and Development Program (RRPD) awards grants to rural health facilities to establish residency programs to train rural physicians.
Objective: To optimally locate rural health facilities eligible for an RRPD grant that would serve populations most in need of rural physician workforce investment.
Methods: A Location-Allocation (L-A) model was used to find 15 additional sites for an RRPD program. Inputs to the model included 7,334 potential hospitals, rural health clinics, and federally qualified health centers, as well as four iterations of population in need (ranging from 8 to 26 million people). Populations were weighted for need based on poverty, access, and rurality. Two L-A criteria were evaluated, minimize distance traveled and maximize coverage.
Results: Eight models of family medicine rural residency demand produced 104 unique facilities in 28 states as being optimal for serving populations with high poverty, high rurality, and low access to primary care. Models differed most between definition of rural used. Eleven facilities were identified in more than one model as being optimal for serving high-need populations.
Implications: RRPD can fill a high need for a stronger primary care workforce by investing in new family medicine rural residency sites primarily in the Southeast and in the West. This analysis can also be applied to other federal grant programs seeking to expand the capacity of facilities to strengthen the rural health workforce.

Low-energy phenomenology of trinification: an effective left-right-symmetric model

description: The trinification model is an interesting extension of the Standard Model (SM) based on the gauge group $SU(3)_C\times SU(3)_L\times SU(3)_R$. We study its low-energy phenomenology by constructing a low-energy effective field theory, thereby reducing the number of particles and free parameters that need to be studied. The resulting model predicts that several new scalar particles have masses in the $\mathcal{O}\left(100\text{ GeV}\right)$ range. We study a few of the interesting phenomenological scenarios, such as the presence of a light fermiophobic scalar in addition to a SM-like Higgs, or a degenerate (twin) Higgs state at 126 GeV. We point out regions of the parameter space that lead to measurable deviations from SM predictions of the Higgs couplings. Hence the trinification model awaits crucial tests at the Large Hadron Collider in the coming years.
