description: Graphyne is a planar two-dimensional carbon allotrope formed by atoms in sp, sp2, and sp3 hybridized states. Topologically graphyne nanotubes (GNTs) can be considered as cylindrically rolled up graphyne sheets, similarly as carbon nanotubes (CNTs) can be considered rolled up graphene sheets. Due to the presence of single, double, and triple bonds, GNTs exhibit porous sidewalls that can be exploited in many diverse applications. In this work, we investigated the mechanical behavior of GNTs under torsional strains through reactive molecular dynamics simulations. Our results show that GNTs are more flexible than CNTs and exhibit 'superplasticity', with fracture angles that are up to 35 times higher than the ones reported to CNTs. This GNT 'superplastic' behavior can be explained in terms of irreversible reconstruction processes (mainly associated with the triple bonds) that occur during torsional strains.

description: The growing interest in new applications involving co-located heterogeneous requirements, such as the Industrial Internet of Things (IIoT) paradigm, poses unprecedented challenges to the uplink wireless transmissions. Dedicated scheduling has been the fundamental approach used by mobile radio systems for uplink transmissions, where the network assigns contention-free resources to users based on buffer-related information. The usage of contention-based transmissions was discussed by the 3rd Generation Partnership Project (3GPP) as an alternative approach for reducing the uplink latency characterizing dedicated scheduling. Nevertheless, the contention-based approach was not considered for standardization in LTE due to limited performance gains. However, 5G NR introduced a different radio frame which could change the performance achievable with a contention-based framework, although this has not yet been evaluated. This paper aims to fill this gap. We present a contention-based design introduced for uplink transmissions in a 5G NR IIoT scenario. We provide an up-to-date analysis via near-product 3GPP-compliant network simulations of the achievable application-level performance with simultaneous Ultra-Reliable Low Latency Communications (URLLC) and Federated Learning (FL) traffic, where the contention-based scheme is applied to the FL traffic. The investigation also involves two separate mechanisms for handling retransmissions of lost or collided transmissions. Numerical results show that, under some conditions, the proposed contention-based design provides benefits over dedicated scheduling when considering FL upload/download times, and does not significantly degrade the performance of URLLC.

description: We consider the asymmetric simple exclusion process (ASEP) on a finite lattice with periodic boundary conditions, conditioned to carry an atypically low current. For an infinite discrete set of currents, parametrized by the driving strength $s_K$, $K \geq 1$, we prove duality relations which arise from the quantum algebra $U_q[\mathfrak{gl}(2)]$ symmetry of the generator of the process with reflecting boundary conditions. Using these duality relations we prove on microscopic level a travelling-wave property of the conditioned process for a family of shock-antishock measures for $N>K$ particles: If the initial measure is a member of this family with $K$ microscopic shocks at positions $(x_1,\dots,x_K)$, then the measure at any time $t>0$ of the process with driving strength $s_K$ is a convex combination of such measures with shocks at positions $(y_1,\dots,y_K)$. which can be expressed in terms of $K$-particle transition probabilities of the conditioned ASEP with driving strength $s_N$.

description: Ferroelectricity, a spontaneous and reversible electric polarization, is found in certain classes of van der Waals (vdW) material heterostructures. The discovery of ferroelectricity in twisted vdW layers provides new opportunities to engineer spatially dependent electric and optical properties associated with the configuration of moiré superlattice domains and the network of domain walls. Here, we employ near-field infrared nano-imaging and nano-photocurrent measurements to study ferroelectricity in minimally twisted WSe2. The ferroelectric domains are visualized through the imaging of the plasmonic response in a graphene monolayer adjacent to the moiré WSe2 bilayers. Specifically, we find that the ferroelectric polarization in moiré domains is imprinted on the plasmonic response of the graphene. Complementary nano-photocurrent measurements demonstrate that the optoelectronic properties of graphene are also modulated by the proximal ferroelectric domains. Our approach represents an alternative strategy for studying moiré ferroelectricity at native length scales and opens promising prospects for (opto)electronic devices.

Evaluating the Implementation of Rapid HIV Testing for Women with Undocumented Status at Labor and Delivery at North Carolina Facilities
Creators: name: Crowley, Christy
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: Abstract Objectives: Documenting HIV status for women in labor is key in the prevention of perinatal transmission from mother to child. Rapid HIV testing at intake for Labor and Delivery (L D) allows for a quick result and the opportunity to implement short course antiretroviral therapy to the mother during labor to interrupt HIV transmission. This survey was designed to evaluate how well the activity of Rapid HIV testing of pregnant women with undocumented status at L D has been operationalized by North Carolina (NC) medical facilities in accordance with NC law. For women presenting at L D, these practices should include confirming HIV status, Rapid HIV testing if status is unavailable, and referral of positive patients and newborns to an HIV disease specialist. In addition, facilities should have established formal policies to ensure that Rapid HIV testing is uniformly conducted for women with undocumented status at L D. Design / Methods: This survey was administered online to Nurse Managers or Nurse Supervisors at NC facilities that had at least one birth recorded in 2010. Each facility was contacted by phone and requested to participate in the survey. Of the 94 facilities identified as having had a birth in 2010, a total of 61 facilities had respondents that completed the survey. Results: The main findings were that 93% of surveyed facilities indicated they do review a woman’s prenatal record to confirm previous HIV testing. However, only 72% of respondents selected that they would always perform an HIV test if previous testing history is unavailable. Additionally, based on the lengths of time respondents indicated for the return of test results (14% said greater than 12 hours), many facilities do not appear to be utilizing Rapid HIV testing. Respondents selected perceived barriers to testing such as lack of patient consent and inadequate time to perform a test that indicate they aren’t fully cognizant of NC law. Approximately 70% of respondents indicated their facility had formal policies regarding HIV testing. Some differences were noted between facilities based on geographical location as well as number of births per facility. Conclusions: Based on the survey results, Rapid HIV testing is not uniformly conducted in NC facilities for women with undocumented status at L D. In order to achieve uniform standard facility practices, the NC Department of Health Human Services (NC DHHS) should at a minimum develop a best practices document that can be distributed to facilities to educate their staff on their responsibilities under the law particularly in the utilization of Rapid HIV testing. Ensuring the availability of Rapid HIV tests at all facilities is also recommended.

description: Arrays of coupled photonic cavities driven by external lasers represent a highly controllable setup to explore photonic transport. In this paper we address (quasi)-steady states of this system that exhibit photonic currents introduced by engineering driving and dissipation. We investigate two approaches: in the first one, photonic currents arise as a consequence of a phase difference of applied lasers and in the second one, photons are injected locally and currents develop as they redistribute over the lattice. Effects of interactions are taken into account within a mean-field framework. In the first approach, we find that the current exhibits a resonant behavior with respect to the driving frequency. Weak interactions shift the resonant frequency toward higher values, while in the strongly interacting regime in our mean-field treatment the effect stems from multiphotonic resonances of a single driven cavity. For the second approach, we show that the overall lattice current can be controlled by incorporating few cavities with stronger dissipation rates into the system. These cavities serve as sinks for photonic currents and their effect is maximal at the onset of quantum Zeno dynamics.

description: We derive and investigate several hydrodynamic formalisms that emerge from a system of classical, ultra-relativistic scalar particles self-interacting via a quartic potential. The specific form of the total cross-section enables the analytical computation of all transport coefficients that appear in Navier-Stokes (NS), Bemfica-Disconzi-Noronha-Kovtun (BDNK), and second-order transient hydrodynamic theories. We solve all these formalisms in a Bjorken flow scenario and show that NS and BDNK theories display unphysical features when gradients become sufficiently large. This implies that these hydrodynamic approaches may not be suitable to describe the early stages of heavy ion collisions.

The Role of the Occupational Health Nurse in Employer Sponsored Substance Abuse Programs:
Creators: name: Hartgens, Janice
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: ABSTRACTAlcohol and drug abuse cost the American workplace an estimated $100 billion per year in lost time (absenteeism), Workers’ Compensation claims, medical costs, lost productivity, and employee turnover. The workforce constitutes 75% of adults struggling with a substance use disorder. Employer sponsored employee treatment - which an employee is more likely to undergo - can save the employer up to $2,607 per worker annually. Contingency Management (CM), a behavioral psychosocial intervention, is among the most effective evidence-based approaches for Substance Use Disorder (SUD) treatment. CM interventions utilize a system of incentives that reward the adoption of targeted behaviors verified by objective measurements. Contingency Management is based on the principles of operant conditioning. The primary premise of operant conditioning is that external events will either increase or decrease the likelihood that a behavior will be repeated.  United Parcel Service (UPS) has used CM to create a therapeutic workplace for over 20 years with an 80% success rate for employees completing the program. The UPS program is similar to the cooperative employer model using continued employment as the reward. In the UPS program, employees are referred to a Substance Abuse Professional (SAP) for evaluation. The UPS occupational health nurse supervisor (OHN) along with a third party administrator (TPA) follow the employee through the successful completion of treatment and follow-up, or termination for failure to successfully complete the program. The occupational health nurse has proven to be valuable in the management of the program. Substance abuse is not just a personal problem; it effects not only the individual, but also their family, friends, co-workers and the employer. Therefore it is a societal problem and employers have a responsibility to the communities they serve to be compliant with the law and to act in the best interest of their employees. Employers who implement a therapeutic workplace are giving their employees an opportunity to overcome a personal challenge, re-engage in the workplace and be successful

description: We introduce MHVAE, a deep hierarchical variational auto-encoder (VAE) that synthesizes missing images from various modalities. Extending multi-modal VAEs with a hierarchical latent structure, we introduce a probabilistic formulation for fusing multi-modal images in a common latent representation while having the flexibility to handle incomplete image sets as input. Moreover, adversarial learning is employed to generate sharper images. Extensive experiments are performed on the challenging problem of joint intra-operative ultrasound (iUS) and Magnetic Resonance (MR) synthesis. Our model outperformed multi-modal VAEs, conditional GANs, and the current state-of-the-art unified method (ResViT) for synthesizing missing images, demonstrating the advantage of using a hierarchical latent representation and a principled probabilistic fusion operation. Our code is publicly available \url{https://github.com/ReubenDo/MHVAE}.

The dynamical evolution of low-mass hydrogen-burning stars, brown dwarfs and planetary-mass objects formed through disc fragmentation

description: Theory and simulations suggest that it is possible to form low-mass hydrogen-burning stars, brown dwarfs and planetary-mass objects via disc fragmentation. As disc fragmentation results in the formation of several bodies at comparable distances to the host star, their orbits are generally unstable. Here, we study the dynamical evolution of these objects. We set up the initial conditions based on the outcomes of the SPH simulations of Stamatellos & Whitworth, and for comparison we also study the evolution of systems resulting from lower-mass fragmenting discs. We refer to these two sets of simulations as set 1 and set 2. At 10 Myr, approximately half of the host stars have one companion left, and approximately 22% (set 1) to 9.8% (set 2) of the host stars are single. Systems with multiple secondaries in relatively stable configurations are common (about 30% and 44%, respectively). The majority of the companions are ejected within 1 Myr with velocities mostly below 5 km/s, with some runaway escapers with velocities over 30 km/s. About 6% (set 1) and 2% (set 2) of the companions pair up into very low-mass binary systems. The majority of these pairs escape as very low-mass binaries, while others remain bound to the host star in hierarchical configurations (often with retrograde inner orbits). Physical collisions with the host star (0.43 and 0.18 events per host star for set 1 and set 2) and between companions (0.08 and 0.04 events per host star for set 1 and set 2) are relatively common and their frequency increases with increasing disc mass. Our study predicts observable properties of very low-mass binaries, low-mass hierarchical systems, the brown dwarf desert, and free-floating brown dwarfs and planetary-mass objects in and near young stellar groupings, which can be used to distinguish between different formation scenarios of very low-mass stars, brown dwarfs and planetary-mass objects.

A GEANT4 based Monte Carlo simulation was performed for background estimation in the first-phase the AMoRE-I detector and shield configuration. Background sources such as $^{238}$U, $^{232}$Th, $^{40}$K, $^{235}$U, and $^{210}$Pb were simulated from inside the crystals, surrounding materials, outer shielding walls of the Y2L cavity. The estimated background rate in the region of interest was found to be $< 1.5 \times 10^{-3}$ counts/keV/kg/yr (ckky). The effects of random coincidences between background and two-neutrino double beta decay of $^{100}$Mo were estimated as a potential background source and its estimated rate was $< 2.3 \times 10^{-4}$ ckky.

The Utility of an Electronic Patient Portal in Improving Patient Engagement and Outcomes in Elderly Patients

description: Danielle Day: The Utility of an Electronic Patient Portal in Improving Patient Engagement and Outcomes in Elderly Patients (Under the Direction of Sue Tolleson-Rinehart) Introduction: ED use for ambulatory sensitive conditions (ASCs) accounts for a third of annual ED visits. Addressing this issue has the potential to reduce costs, improve patient outcomes and prevent ED overcrowding. Electronic patient portals (EPPs) are widely implemented and can improve access to care. Since some older patients use the Internet less regularly than others, the utility of EPPs especially needs to be investigated in this population. The aim of this study was to identify whether the UNC EPP, My UNC Chart, is associated with emergency department visits for ASCs in geriatric patients. Methods: This was a survey study design of a cross sectional convenience sample from the waiting room of the Geriatrics Specialty Clinic at UNC performed in June 2017. The primary outcome was recent ED visit for an ASC. Secondary outcomes included ED visits and hospital admissions in the past year. The exposure variable was use of My UNC Chart, an online patient portal. Bivariate and multivariate analyses included important covariates and the outcomes of interest. Results: PCP contact type via My UNC Chart was statistically significantly associated with the primary outcome (R:-0.5, CI: -0.99, -0.01). The additional covariates investigated in the bivariate analysis included whether, how often, and via what kind of device patients used My UNC Chart. I also measured opinions about My UNC Chart (helpfulness, enjoyability, assistance with managing care), patients' general health status, and change in that status over the past month and past year. I created a general technology use score, and asked participants about their most recent ED visit, primary care provider contact before ED visit, and, finally, their sex, race, age. and education level. I found no significant associations between My UNC Chart use and the secondary outcomes of frequency of ED visits and hospitalizations in the past year. The multivariate analysis also failed to produce significant relationships. I did not find a correlation between the technology use score and use of My UNC Chart. Conclusion: My UNC Chart use did not predict lower numbers of recent ED visit for ASCs, ED visit frequency in the past year, or hospitalizations in the past year in this study. Contact with PCPs via My UNC Chart before recent ED visits was associated with increased use of the ED for ambulatory sensitive conditions, although these data are difficult to interpret. Future research should focus on understanding these relationships in larger, more geographically diverse elderly populations.

description: Vectorial partners of the Standard Model quarks and leptons are predicted in many dynamical models of electroweak symmetry breaking. The most easily accessible of these new particles, either due to mass or couplings, are typically expected to be the partners of the third-generation fermions. It is therefore essential to explore the signatures of these particles at future high-energy colliders. We study the potential of a high-energy muon collider to singly produce a vector-like top-quark partner via an electroweak dipole moment operator, such an operator being typical of composite constructions beyond the Standard Model. We use a phenomenological model for third-generation quarks and their partners that satisfies an extended custodial symmetry. This automatically protects the $W$-boson and $Z$-boson masses from receiving large electroweak corrections, and it allows the model to be viable given current electroweak data. We demonstrate that cross sections associated with dipole-induced vector-like quark production can easily exceed those inherent to more conventional single-production modes via ordinary electroweak couplings. We then explore the associated phenomenology, and we show that at least one (and often more than one) of the extra vector-like states can be studied at high-energy muon colliders. Typical accessible masses are found to range up to close to the kinematic production threshold, when the vector-like partners are produced in combination with an ordinary top quark.

subject: FOS: Mathematics

description: We recall criteria on the spectrum of Jacobi matrices such that the corresponding isospectral torus consists of periodic operators. Motivated by those known results for Jacobi matrices, we define a new class of operators called GMP matrices. They form a certain Generalization of matrices related to the strong Moment Problem. This class allows us to give a parametrization of almost periodic finite gap Jacobi matrices by periodic GMP matrices. Moreover, due to their structural similarity we can carry over numerous results from the direct and inverse spectral theory of periodic Jacobi matrices to the class of periodic GMP matrices. In particular, we prove an analogue of the remarkable "magic formula" for this new class.

Methods: Eligible women enrolled who were attending family medicine or obstetric/gynecology clinics in Central North Carolina between February 2001 and May 2003, had quit smoking (cotinine verified) before thirty weeks gestation, and agreed to a face-to-face interview assessment 4 months postpartum. This reports documents interviews with the first 57 women (24 smoke-free, 33 relapse) who completed the study. Results: While similar themes explained the cessation process for women who relapsed and those remaining smoke-free, different factors explained relapse and relapse prevention. Fetal health was the motivating factor for cessation before and during pregnancy. Stress, socializing with smokers, cravings, weight gain and return to work postpartum tempted both groups to smoke. The smoke-free group overcame temptations through strong social/spousal support, growing self-confidence, and internalized beliefs in improved maternal and infant health. The relapse group lacked this level of social support and perception of maternal health benefits. Both groups established rules to limit infant exposure to second-hand smoke. Conclusion: Recommendations for relapse prevention include clinically emphasizing maternal and infant health, advice on resisting smoking temptations, increasing the incentive to remain quit, providing stress relief alternatives, providing support services, and reducing access to cigarettes. Community interventions targeting pregnant women and postpartum mothers who have quit smoking should compensate for varying levels of support, incorporate family, friends and spouses, and connect women with other ex-smokers.

description: In previous works, we proposed to estimate cosmological parameters with the artificial neural network (ANN) and the mixture density network (MDN). In this work, we propose an improved method called the mixture neural network (MNN) to achieve parameter estimation by combining ANN and MDN, which can overcome shortcomings of the ANN and MDN methods. Besides, we propose sampling parameters in a hyper-ellipsoid for the generation of the training set, which makes the parameter estimation more efficient. A high-fidelity posterior distribution can be obtained using $\mathcal{O}(10^2)$ forward simulation samples. In addition, we develop a code-named CoLFI for parameter estimation, which incorporates the advantages of MNN, ANN, and MDN, and is suitable for any parameter estimation of complicated models in a wide range of scientific fields. CoLFI provides a more efficient way for parameter estimation, especially for cases where the likelihood function is intractable or cosmological models are complex and resource-consuming. It can learn the conditional probability density $p(\boldsymbolθ|\boldsymbol{d})$ using samples generated by models, and the posterior distribution $p(\boldsymbolθ|\boldsymbol{d}_0)$ can be obtained for a given observational data $\boldsymbol{d}_0$. We tested the MNN using power spectra of the cosmic microwave background and Type Ia supernovae and obtained almost the same result as the Markov Chain Monte Carlo method. The numerical difference only exists at the level of $\mathcal{O}(10^{-2}σ)$. The method can be extended to higher-dimensional data.

A Recommendation for Expanding Teen Pregnancy Prevention Programs and Pregnancy Support Services in North Carolina Colleges & Universities
Creators: name: Pless, Laura

Year: 2008

description: Both the national and North Carolina teen birth rates are increasing for the first time in over a decade. Most of the statistics reported lump pregnant adolescents into a 15-19 year old age group, but the rate of increase can be primarily attributed to the older 18-19 year olds ("Reported Pregnancies," 2007). While teen pregnancy prevention programs have been largely successful in continually lowering birth rates and pregnancy rates over the last 20 years ("NC Teen Pregnancy," 2007), there is a gap or deficiency in pregnancy prevention programs and pregnancy support services offered at colleges and universities. This may be responsible for the recent increase in the number of pregnant adolescents attending college, and if left unchecked, could have significant financial implications for both the taxpayer and the pregnant young women. Pregnant adolescents often face birth complications, physical and psychological stress and financial hardships that jeopardize their health and pregnancy. Without adequate support services a pregnant teen often feels they have no choice but to abort their pregnancy or drop out of school. It is imperative that funds are appropriated by legislative action specifically aimed at creation and funding of new primary and secondary pregnancy prevention programs and pregnancy support services for this 18-19 year old age group. While some colleges have responded appropriately to this new challenge and should be looked at as model examples, many are as yet, unprepared, unwilling or unable to deal with this special needs population. Programs should be comprehensive and have specific goals, measurable objectives, and a means of evaluation. Successful programs should be considered for renewable multi-year funding based on outcomes.
