description: Time-domain thermoreflectance (TDTR) and frequency-domain thermoreflectance (FDTR) have been widely used for non-contact measurement of anisotropic thermal conductivity of materials with high spatial resolution. However, the requirement of high thermoreflectance coefficient restricts the choice of metal coating and laser wavelength. The accuracy of the measurement is often limited by the high sensitivity to the radii of the laser beams. We describe an alternative frequency-domain pump-probe technique based on probe beam deflection. The beam deflection is primarily caused by thermoelastic deformation of the sample surface with a magnitude determined by the thermal expansion coefficient of the bulk material to measure. We derive an analytical solution to the coupled elasticity and heat diffusion equations for periodic heating of a multilayer sample with anisotropic elastic constants, thermal conductivity, and thermal expansion coefficients. In most cases, a simplified model can reliably describe the frequency dependence of the beam deflection signal without knowledge of the elastic constants and thermal expansion coefficients of the material. The magnitude of the probe beam deflection signal is larger than the maximum magnitude achievable by thermoreflectance detection of surface temperatures if the thermal expansion coefficient is greater than 5x10^(-6) /K. The sensitivity to laser beam radii is suppressed when a larger beam offset is used. We find nearly perfect matching of the measured signal and model prediction, and measure thermal conductivities within 6% of accepted values for materials spanning the range of polymers to gold, 0.1 - 300 W/(m K).

description: Motivated by the recent resonant inelastic x-ray scattering (RIXS) experiment for the electron-doped cuprates Nd_{2-x}Ce_{x}CuO_{4} with x around 0.15, we compute the density-density correlation function in the t-J model on a square lattice by including interlayer hopping and the long-range Coulomb interaction. We find that collective charge excitations are realized not inside the particle-hole continuum, but above the continuum as plasmons. The plasmon mode has a rather flat dispersion near the in-plane momentum q=(0,0) with a typical excitation energy of the order of the intralayer hopping t when the out-of-plane momentum qz is zero. However, when qz becomes finite, the plasmon dispersion changes drastically near q=(0,0), leading to a strong dispersive feature with an excitation gap scaled by the interlayer hopping tz. We discuss that the mode recently observed by RIXS near q=(0,0) can be associated with the plasmon mode with a finite qz.

description: We derive new sum rules for the form factors of the $B_c\to J/ψ\, \ell \barν_\ell$ semileptonic transitions, employing the vacuum-to-$B_c$ correlation function of the $J/ψ$-interpolating and $b\to c$ weak currents. In the heavy quark limit and at a space-like momentum transfer to the weak current, a local operator-product expansion is valid for this correlation function. As a result, in the leading power, the non-perturbative input is reduced to the decay constant of $B_c$ meson. Furthermore, applying hadronic dispersion relation in the $J/ψ$ channel, we find that a non-vanishing OPE spectral density in the duality interval of $J/ψ$ emerges only at $\mathcal{O}(α_s)$. We calculate this density in the relevant kinematic regime. The $B_c\to J/ψ$ form factors at space-like momentum transfer are then calculated from the new sum rules.

description: A pair density wave (PDW) is a superconductor whose order parameter is a periodic function of space, without an accompanying spatially-uniform component. Since PDWs are not the outcome of a weak-coupling instability of a Fermi liquid, a generic pairing mechanism for PDW order has remained elusive. We describe and solve models having robust PDW phases. To access the intermediate coupling limit, we invoke large $N$ limits of Fermi liquids with repulsive BCS interactions that admit saddle point solutions. We show that the requirements for long range PDW order are that the repulsive BCS couplings must be non-monotonic in space and that their strength must exceed a threshold value. We obtain a phase diagram with both finite temperature transitions to PDW order, and a $T=0$ quantum critical point, where non-Fermi liquid behavior occurs.

description: We formulate a self-consistent model of the integer quantum Hall effect on an infinite strip, using boundary conditions to investigate the influence of finite-size effects on the Hall conductivity. By exploiting the translation symmetry along the strip, we determine both the general spectral properties of the system for a large class of boundary conditions respecting such symmetry, and the full spectrum for (fibered) Robin boundary conditions. In particular, we find that the latter introduce a new kind of states with no classical analogues, and add a finer structure to the quantization pattern of the Hall conductivity. Moreover, our model also predicts the breakdown of the quantum Hall effect at high values of the applied electric field.

description: The violent merger of two carbon-oxygen white dwarfs has been proposed as a viable progenitor for some Type Ia supernovae. However, it has been argued that the strong ejecta asymmetries produced by this model might be inconsistent with the low degree of polarisation typically observed in Type Ia supernova explosions. Here, we test this claim by carrying out a spectropolarimetric analysis for the model proposed by Pakmor et al. (2012) for an explosion triggered during the merger of a 1.1 M$_{\odot}$ and 0.9 M$_{\odot}$ carbon-oxygen white dwarf binary system. Owing to the asymmetries of the ejecta, the polarisation signal varies significantly with viewing angle. We find that polarisation levels for observers in the equatorial plane are modest ($\lesssim$ 1 per cent) and show clear evidence for a dominant axis, as a consequence of the ejecta symmetry about the orbital plane. In contrast, orientations out of the plane are associated with higher degrees of polarisation and departures from a dominant axis. While the particular model studied here gives a good match to highly-polarised events such as SN 2004dt, it has difficulties in reproducing the low polarisation levels commonly observed in normal Type Ia supernovae. Specifically, we find that significant asymmetries in the element distribution result in a wealth of strong polarisation features that are not observed in the majority of currently available spectropolarimetric data of Type Ia supernovae. Future studies will map out the parameter space of the merger scenario to investigate if alternative models can provide better agreement with observations.

Outcomes Research Using Claims Databases: A Critical Review and Case Study
Creators: name: Wittbrodt, Eric
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: Outcomes research (OR) is an evolving and critical part of health sciences research due to its focus on the improvement of patient care in the practice setting. Evidence included in OR spans all available clinical information, from data generated by randomized controlled trials to real-world clinical, economic, humanistic, patient-reported, and patient satisfaction data. Comparative effectiveness research (CER) is a branch of OR that compares the overall benefit or cost of two active interventions. The use of claims databases has emerged as a valid, rigorous, and efficient source of data for CER. Due to the inability to control for all confounders, techniques such as propensity score matching and quality checks are necessary to maintain data accuracy and validity. A case study comparing two oral medications used in the treatment of gout will be used to illustrate the techniques, advantages, and disadvantages of using claims databases in OR.

description: Heavy elements (beyond iron) are formed in neutron capture nucleosynthesis processes. We have proposed a simple unified model to investigate the neutron capture nucleosynthesis in arbitrary neutron density environment. We have also investigated what neutron density is required to reproduce the measured abundance of nuclei assuming equilibrium processes. We found both of these that the medium neutron density has a particularly important role at neutron capture nucleosynthesis. About these results most of the nuclei can formed at medium neutron capture density environment e.g. in some kind of AGB stars. Besides these observations our model is capable to use educational purpose.

Association between Physical Activity and Risk of Occupational Injury
Creators: name: Feltner, Cindy, MD
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: Background: Physical activity is associated with lower rates of chronic diseases and injuries in the elderly. The objective of this study was to determine whether self-reported physical activity and participation in a workplace physical fitness program are associated with lower rates of Workers’ Compensation (WC) claims, controlling for other risk factors. Methods: This retrospective cohort study examined data from 22,831 health care and university employees (72,633 full-time equivalents [FTE]) with at least 1 health risk appraisal between 2003 and 2009. The main outcome measure was stratified rates of WC claims per FTE. Independent variables included self-reported physical activity, participation in a workplace fitness program, BMI, sex, age, race/ethnicity, smoking status, employment duration, and occupational group. Results of bivariate analyses and multivariate Poisson regression models are reported. Results: Moderately physically active employees had fewer injuries over time than did those who reported no regular activity, in a generally linear relationship ranging from 6.53 claims per 100 FTEs for sedentary persons to 4.53 claims per 100 FTEs for those who exercise 4-5 days per week. Those who exercise every day; their claims approached those who reported no regular physical activity. Controlling for other independent variables, employees who exercised for 30 minutes 2-3 days per week or 4-5 days per week had lower rates of injury than did the sedentary (IRR= 0.85 and 0.86 respectively). Participation in a workplace physical activity program had no apparent effect. Conclusions: Moderate levels of self-reported physical activity appear to predict lower rates of workplace injury.
Scattering theory for the radial $\dot H^{1/2}$-critical wave Equation with a cubic convolution

description: In this paper, we study the global well-posedness and scattering for the wave equation with a cubic convolution $\partial_{t}^2u-Δu=\pm(|x|^{-3}\ast|u|^2)u$ in dimensions $d\geq4$. We prove that if the radial solution $u$ with life-span $I$ obeys $(u,u_t)\in L_t^\infty(I;\dot H^{1/2}_x(\mathbb R^d)\times\dot H^{-1/2}_x(\mathbb R^d))$, then $u$ is global and scatters. By the strategy derived from concentration compactness, we show that the proof of the global well-posedness and scattering is reduced to disprove the existence of two scenarios: soliton-like solution and high to low frequency cascade. Making use of the No-waste Duhamel formula and double Duhamel trick, we deduce that these two scenarios enjoy the additional regularity by the bootstrap argument of [Dodson,Lawrie, Anal.PDE, 8(2015), 467-497]. This together with virial analysis implies the energy of such two scenarios is zero and so we get a contradiction.

description: Electrically controllable quantum coherence in quantum dot clusters and arrays based on graphene stripes with zigzag atomic edges (ZZ-stripes) is studied using the Dirac equation and S-matrix technique. We find that respective multiqubit circuits promise stable operation up to room temperatures when the coherence time is prolonged up by a few orders of magnitude through the intrinsic spectral narrowing owing to electron transport between at bands in adjacent sections. Respectively, the coupling of qubits to a noisy environment is diminished, while the inelastic electron-phonon scattering is suppressed. The Stark splitting technique enables a broad range of operations such as all{electrical tuning of the energy level positions and width, level splitting, controlling of the inter-qubit coupling, and the coherence time. At the resonant energies, the phase coherence spreads over thousands of periods. Such phenomena potentially can be utilized in quantum computing and communication applications at room temperature.

description: Continuing medical education must stimulate and maintain the interest and participation of physicians, by identifying and meeting their educational needs. Educational material for busy professionals must be concise with a format suited to the reading audience. Public Health newsletters have the potential to reach a large audience, and are not costly to prepare. There has never been such a Public Health newsletter available for community healthcare workers in our regional city of Geelong, in Victoria, Australia. This thesis explores the key stages involved in planning, developing, and evaluating a Public Health newsletter for healthcare Workers in this region. A working party, developed in 2008, oversaw the creation of a vision, format and content for the monthly newsletter which launched in February 2009. An evaluation of the newsletter was undertaken in February 2010 via a survey to gauge the utility and relevance of the newsletter. More than 80% of respondents found the newsletter useful, interesting, informative and relevant to their practice, and nearly 90% thought the bulletin was the right length. Positive feedback was also received about the inclusion of pictures and graphs in the newsletter. The newsletter continues to expand both its list of contributing authors and its distribution list. Further evaluations may be required in the future to determine the direction of the newsletter.

description: Rare giant low surface brightness galaxies (gLSBGs) act as a stress test for the current galaxy formation paradigm. To answer the question `How rare are they?' we estimate their volume density in the local Universe. A visual inspection of 120~sq.~deg. covered by deep Subaru Hyper Suprime-Cam data was performed independently by four team members. We detected 42 giant disky systems (30 of them isolated) at $z\leq0.1$ with either $g$-band 27.7~mag~arcsec$^{-2}$ isophotal radius or four disc scalelengths $4h \geq 50$~kpc, 37 of which (including 25 isolated) had low central surface brightness ($μ_{0,g}\ge 22.7$ mag~arcsec$^{-2}$). This corresponds to volume densities of 4.70$\times 10^{-5}$ Mpc$^{-3}$ for all galaxies with giant extended discs and 4.04$\times 10^{-5}$ Mpc$^{-3}$ for gLSBGs, which converts to $\sim $12,700 such galaxies in the entire sky out to $z<0.1$. These estimates agree well with the result of the EAGLE cosmological hydrodynamical simulation. Giant disky galaxies represent the large-size end of the volume density distribution of normal-sized spirals, suggesting the non-exceptional nature of giant discs. We observe a high active galactic nucleus fraction among the newly found gLSBGs.

The HIV Crisis in African Americans
Creators: name: Anderson, Jennifer A.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: Human Immunodeficiency Virus infection (HIV) has reached alarming proportions in the African American or black population. According to the Centers for Disease Control and Prevention (CDC), HIV has affected African American men, women, and children at a much higher rate than any other racial or ethnic population and continues to be a serious public health threat (Fact Sheet: HIV/AIDS Among African Americans, 2009). The combinations of factors contributing to this health disparity are complex. Social determinants such as poverty, unemployment and underemployment, and lack of access to health care and treatment all contribute to the problem. Problems unique to minorities, especially African Americans, include historical and current racism and discrimination, high rates of illicit drug use, incarceration, the dynamics of sexual networks, and stigma related to HIV diagnoses. In order to address this problem, public health leaders will need to collaborate with leaders in African American communities to design HIV prevention initiatives that involve strategies which are culturally acceptable and effective for this population. The interventions need to go beyond individual level interventions, and will need to address the societal and structural factors that exacerbate this disease.

description: We present a multi-wavelength analysis of the dwarf Seyfert-2 galaxy J$144013+024744$, a candidate obscured active galactic nucleus (AGN) thought to be powered by an intermediate-mass black hole (IMBH, $M_\bullet \approx 10^{4-6} M_\odot$) of mass $M_{\bullet} \sim 10^{5.2}M_\odot$. To study its X-ray properties, we targeted J$144013+024744$ with NuSTAR for $\approx 100$ ks. The X-ray spectrum was fitted with absorbed power law, Pexmon and a physical model (RXTorus). A Bayesian X-ray analysis was performed to estimate the posteriors. The phenomenological and the physical models suggest the AGN to be heavily obscured by a column density of $N_{\rm H} = (3.4-7.0)\times10^{23}$ cm$^{-2}$. In particular, the RXTorus model with a sub-solar metallicity suggests the obscuring column to be almost Compton-thick. We compared the $2-10$ keV intrinsic X-ray luminosity with the inferred X-ray luminosities based on empirical scaling relations for unobscured AGNs using $L_{\rm [OIV](25.89μ{\rm m})}$, $L_{[{\rm OIII}](5007 {\rm angstrom})}$, and $L_{6\rm μm}$ and found that the high-excitation $[{\rm OIV}]$ line provides a better estimate of the intrinsic $2-10$ keV X-ray luminosity ($L_{2-10}^{\rm int} \sim 10^{41.41}{\rm erg s}^{-1}$). Our results suggest that J$144013+024744$ is the first type-2 dwarf galaxy that shows X-ray spectroscopic evidence for obscuration. The column density that we estimated is among the highest measured to date for IMBH-powered AGNs, implying that a typical AGN torus geometry might extend to the low-mass end. This work has implications for constraining the black hole occupation fraction in dwarf galaxies using X-ray observations.

description: Single ionization of H$_2$ molecules exposed to strong and short laser pulses is investigated by a semi-classical method. Three laser characteristics are considered: i) The carrier-wave frequency corresponds to wavelengths covering and bridging the two ionization regimes: From tunnel ionization (TI) at 800 nm to multiphoton ionization (MPI) at 266 nm. ii) Values of the peak intensity are chosen within a window to eliminate competing double ionization processes. iii) Particular attention is paid to the polarization of the laser field, which can be linearly or circularly polarized. The results and their interpretation concern two observables, namely the end-of-pulse total ionization probability and vibrational distribution generated in the cation H$_2^+$. The most prominent findings are an increased ionization efficiency in circular polarization and a vibrational distribution of the cation that favors lower-lying levels than those that would be populated in a vertical (Franck-Condon) ionization, leading to non Franck-Condon distributions, both in linear and circular polarizations.

A Community's Response to Infant Mortality: Forsyth County, North Carolina
Creators: name: Gonwa, Joanne Gail
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: Disparities in infant mortality health rates are a persistent problem in today’s world. Infant mortality rates within the United States do not compare favorably with similar industrialized nations worldwide. Efforts to reduce infant mortality rates in the United States have shown some progress yet have failed to significantly impact the disparities in infant mortality among ethnic/racial groups. Forsyth County, North Carolina has made a comprehensive community wide effort to address these disparities in infant mortality. This paper purposes to examine the root causes of infant mortality within Forsyth County, describe the efforts to reduce overall infant mortality within the county, and explore further solutions to this continuing health problem.
The Origin of Condensation Energy Scaling of the Fe-based superconductors

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: Motivated by the recent experiment of the non-BCS scaling relation of the condensation energy $ΔCE$ vs. $T_c$ ($ΔCE \sim T_c ^β, β\approx 3.5$) [PRB 89 140503 (2014)] for the Fe-based superconductors, we studied the CE and $T_c$ of the multiband BCS superconductors. We showed that the experimentally observed anomalous scaling relation $ΔCE \sim T_c ^{3.5}$ is well reproduced by the two-band BCS superconductor paired by a dominant interband interaction ($V_{inter} > V_{intra}$). Our result implies that this seemingly non-BCS-like scaling behavior, on the contrary to the common expectation, is in fact a strong experimental evidence that the pairing mechanism of the Fe-based superconductors is genuinely a BCS mechanism, meaning that "the Cooper pairs are formed by the itinerant carriers glued by a pairing interaction."

Universal topological marker

description: We elaborate that for topological insulators and topological superconductors described by Dirac models in any dimension and symmetry class, the topological order can be mapped to lattice sites by a universal topological marker. Deriving from a recently discovered momentum-space universal topological invariant, we introduce a topological operator that consists of alternating projectors to filled and empty lattice eigenstates and the position operators, multiplied by the Dirac matrices that are omitted in the Hamiltonian. The topological operator projected to lattice sites yields the topological marker, whose form is explicitly constructed for every topologically nontrivial symmetry class from 1D to 3D. The off-diagonal elements of the topological operator yields a nonlocal topological marker, which decays with a correlation length that diverges at topological phase transitions, and represents a Wannier state correlation function. Various prototype examples, including Su-Schrieffer-Heeger model, Majorana chain, Chern insulators, Bernevig-Hughes-Zhang model, 2D chiral and helical $p$-wave superconductors, lattice model of $^{3}$He B-phase, and 3D time-reversal symmetric topological insulators, etc, are employed to demonstrate the ubiquity of our formalism.

description: After in quiescence for 49 years, 4U~1730--22 became active and had two outbursts in 2021 \& 2022; ten thermonuclear X-ray bursts were detected with Insight-HXMT. Among them, the faintest burst showed a double-peaked profile, placing the source as the 5th accreting neutron star (NS) exhibiting double/triple-peaked type-I X-ray bursts; the other bursts showed photospheric radius expansion (PRE). The properties of double-peaked non-PRE burst indicate that it could be related to a stalled burning front. For the five bright PRE bursts, apart from the emission from the neutron star (NS) surface, we find the residuals both in the soft ($<$3 keV) and hard ($>$10 keV) X-ray band. Time-resolved spectroscopy reveals that the excess can be attributed to an enhanced pre-burst/persistent emission or the Comptonization of the burst emission by the corona/boundary-layer. We find, the burst emission shows a rise until the photosphere touches down to the NS surface rather than the theoretical predicted constant Eddington luminosity. The shortage of the burst emission in the early rising phase is beyond the occlusion by the disk. We speculate that the findings above correspond to that the obscured part (not only the lower part) of the NS surface is exposed to the line of sight due to the evaporation of the obscured material by the burst emission, or the burst emission is anisotropic ($ξ>1$) in the burst early phase. In addition, based on the average flux of PRE bursts at their touch-down time, we derive a distance estimation as 10.4 kpc.

description: The work is focused on the characterization of a long-range interacting complex in the reaction between atomic oxygen, in its ground state O(3P) and acrylonitrile CH2CHCN, also known as vinyl cyanide or cyano ethylene, through electronic structure calculations. Different ab initio methods have been used in order to understand which functional provides a better description of the long-range interaction. The results of the work suggest that B2PLYPD3 gives the best description of the long-range interaction, while CAM-B3LYP represents the best compromise between chemical accuracy and computational cost.

Lorentz symmetry violating Lifshitz-type field theories
Creators: name: Rizza, Emiliano

Publisher: name: arXiv
Year: 2022
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We discuss the ultraviolet sector of 3+1 dimensional Lifshitz-type anisotropic higher derivative scalar, fermion and gauge field theories, with anisotropy exponent z=3 and with explicit breaking of Lorentz symmetry. By discarding from the action all momentum dependent vertex operators, which is essential to avoid phenomenologically unacceptable deformations of the light cone, we find that renormalizable scalar self-interaction and Yukawa-like couplings are, in general, asymptotically free. However, the requirement of cancelling momentum dependent vertex operators is incompatible with gauge symmetry and, therefore, for this kind of theories, gauge symmetry as well as Lorentz symmetry are recovered only as emergent properties below some energy scale M, that must be constrained from experiments. The quantum corrections to the scalar mass and their impact on the hierarchy problem are also analyzed.

description: An abundance decrease in carbon- and oxygen-bearing species relative to dust has been frequently found in planet-forming disks, which can be attributed to an overall reduction of gas mass. However, in the case of TW Hya, the only disk with gas mass measured directly with HD rotational lines, the inferred gas mass ($\lesssim$0.005 solar mass) is significantly below the directly measured value ($\gtrsim$0.05 solar mass). We show that this apparent conflict can be resolved if the elemental abundances of carbon and oxygen are reduced in the upper layers of the outer disk but are normal elsewhere (except for a possible enhancement of their abundances in the inner disk). The implication is that in the outer disk, the main reservoir of the volatiles (CO, water, ...) resides close to the midplane, locked up inside solid bodies that are too heavy to be transported back to the atmosphere by turbulence. An enhancement in the carbon and oxygen abundances in the inner disk can be caused by inward migration of these solid bodies. This is consistent with estimates based on previous models of dust grain dynamics. Indirect measurements of the disk gas mass and disk structure from species such as CO will thus be intertwined with the evolution of dust grains, and possibly also with the formation of planetesimals.
