description: Astrophysical tests of the stability of fundamental couplings, such as the fine-structure constant $α$, are becoming an increasingly powerful probe of new physics. Here we discuss how these measurements, combined with local atomic clock tests and Type Ia supernova and Hubble parameter data, constrain the simplest class of dynamical dark energy models where the same degree of freedom is assumed to provide both the dark energy and (through a dimensionless coupling, $ζ$, to the electromagnetic sector) the $α$ variation. Specifically, current data tightly constrains a combination of $ζ$ and the present dark energy equation of state $w_0$. Moreover, in these models the new degree of freedom inevitably couples to nucleons (through the $α$ dependence of their masses) and leads to violations of the Weak Equivalence Principle. We obtain indirect bounds on the Eötvös parameter $η$ that are typically stronger than the current direct ones. We discuss the model-dependence of our results and briefly comment on how the forthcoming generation of high-resolution ultra-stable spectrographs will enable significantly tighter constraints.

description: We address the issue of identifying the mediators of effective interactions in cuprates superconductors. Specifically, we use inversion theory to analyze Raman spectra of optimally and over-doped La$_{2-x}$Sr$_x$CuO$_4$ samples. This allows us to extract the so-called glue function without making any a priori assumption based on any specific model. We use instead two different techniques, namely the singular value decomposition and a multi-rectangle decomposition. With both techniques we find consistent results showing that: i) two distinct excitations are responsible for the glue function, which have completely different doping dependence. One excitation becomes weak above optimal doping, where on the contrary the other keeps (or even slightly increases) its strength; ii) there is a marked temperature dependence on the weight and spectral distribution of these excitation, which therefore must have a somewhat critical character. It is quite natural to identify and characterize these two distinct excitations as damped antiferromagnetic spin waves and damped charge density waves, respectively. This sets the stage for a scenario in which superconductivity is concomitant and competing with a charge ordering instability.

description: Using the Ultra-relativistic Quantum Molecular Dynamics ({\tt UrQMD}) model, we investigate the azimuthal correlations in p--Pb collisions at $\sqrt{s_{_{\rm NN}}}=5.02$ TeV. It is shown that the simulated hadronic p--Pb system can not generate the collective flow signatures, but mainly behaves as a non-flow dominant system. However, the characteristic $v_{2}(p_{\rm T})$ mass-ordering of pions, kaons and protons is observed in {\tt UrQMD} simulations, which is the consequence of hadronic interactions and not necessarily associated with strong fluid-like expansions.

description: The purpose of this particular study was to examine the DiSC styles of intercollegiate football players. This study observed the DiSC assessment results of 127 collegiate football players, categorized into Dominance (D), influence (i), Steadiness (S), and Conscientiousness (C). There were 127 points of data used to analyze DiSC style based on the eight different positions as well as offense compared to defense. After completing chi-square analyses, there were two outputs that were significantly different from the sample mean. Most notably, it was shown that the Dominance based quarterbacks were significant. While no significance was found between offensive and defensive units. Overall, this study adds to the literature demonstrating the vast heterogeneity of members of a football team.

description: Brueckner theory is used to investigate the properties of hyperons in nuclear matter. The hyperon-nucleon interaction is taken from chiral effective field theory at next-to-leading order with SU(3) symmetric low-energy constants. Furthermore, the underlying nucleon-nucleon interaction is also derived within chiral effective field theory. We present the single-particle potentials of Lambda and Sigma hyperons in symmetric and asymmetric nuclear matter computed with the continuous choice for intermediate spectra. The results are in good agreement with the empirical information. In particular, our calculation gives a repulsive Sigma-nuclear potential and a weak Lambda-nuclear spin-orbit force.

description: Strong laser pulses can control superconductivity, inducing non-equilibrium transient pairing by leveraging strong-light matter interaction. Here we demonstrate theoretically that equilibrium ground-state phonon-mediated superconductive pairing can be affected through the vacuum fluctuating electromagnetic field in a cavity. Using the recently developed ab initio quantum electrodynamical density-functional theory approximation, we specifically investigate the phonon-mediated superconductive behavior of MgB$_2$ under different cavity setups and find that in the strong light-matter coupling regime its superconducting transition temperature can be, in principles, enhanced by $\approx 73\%$ ($\approx 40\%$) in an in-plane (out-of-plane) polarized cavity. However, in a realistic cavity, we expect the T$_{\rm{c}}$ of MgB$_2$ can increase, at most, by $5$ K via photon vacuum fluctuations. The results highlight that strong light-matter coupling in extended systems can profoundly alter material properties in a non-perturbative way by modifying their electronic structure and phononic dispersion at the same time. Our findings indicate a pathway to the experimental realization of light-controlled superconductivity in solid-state materials at equilibrium via cavity-material engineering.

description: A celebrated result due to Wolff says if $E$ is a compact subset of ${\Bbb R}^2$, then the Lebesgue measure of the distance set $Δ(E)=\{|x-y|: x,y \in E \}$ is positive if the Hausdorff dimension of $E$ is greater than $\frac{4}{3}$. In this paper we improve the $\frac{4}{3}$ barrier by a small exponent for Cartesian products. In higher dimensions, also in the context of Cartesian products, we reduce Erdogan's $\frac{d}{2}+\frac{1}{3}$ exponent to $\frac{d^2}{2d-1}$. The proof uses a combination of Fourier analysis and additive comibinatorics.

description: Massive B-type stars with strong magnetic fields and fast rotation are very rare and provide a mystery for theories of both star formation and magnetic field evolution. Only two such stars, called sigma Ori E analogs, were previously known. Recently, a team involved in APOGEE, one of the Sloan Digital Sky Survey III programs, announced the discovery of two additional rigidly rotating magnetosphere stars, HD23478 and HD345439. The presence of magnetic fields in these newly discovered sigma Ori E analogs was not investigated in the past. In the framework of our ESO Large Programme, and one normal ESO programme, we carried out low-resolution FORS2 spectropolarimetric observations of HD23478 and HD345439. From the measurements using hydrogen lines, we discover a rather strong longitudinal magnetic field of the order of up to 1.5kG in HD23478, and up to 1.3kG using the entire spectrum. The analysis of HD345439 using four subsequent spectropolarimetric subexposures does not reveal the presence of a magnetic field at a significance level of 3sigma. On the other hand, the inspection of individual subexposures indicates that HD345439 may host a strong magnetic field, rapidly varying over 88 minutes. A hint at the fast rotation of HD345439 is also given by the behaviour of several metallic and He I lines in the low-resolution FORS2 spectra, showing profile variations already on such a short time scale.

description: A primary problem for perturbative QCD analyses is how to set the renormalization scale of the QCD running coupling in order to achieve maximally precise fixed-order predictions for physical observables. The Principle of Maximum Conformality (PMC) eliminates the ambiguities associated with the conventional renormalization scale-setting procedure, giving predictions which are independent of the choice of renormalization scheme. The scales of the QCD couplings and the effective number of quark flavors are set order by order in the pQCD series. The PMC has a solid theoretical foundation, satisfying the standard renormalization group invariance and all of the the self-consistency conditions derived from the renormalization group......In this brief report, we summarize the results of our recent PMC applications for a number of collider processes, emphasizing their generality and applicability....... These results demonstrate that the application of the PMC systematically eliminates a major theoretical uncertainty for pQCD predictions, thus increasing the sensitivity of the colliders to possible new physics beyond the Standard Model.

Understanding the Implications: Tensions between Federal versus State and Technology-driven versus Technology-agnostic Renewable Energy Policies
Creators: name: Kaiser, Leah C.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: Energy generation is inextricably linked to climate change but there is debate concerning the most effective policies for “greening” our system. Federal-level polices are ideally situated to take advantage of economies of scale while rising above jurisdictional constraints. Yet state-level policies often are more politically feasible and allow for greater flexibility. Thus far, states have pursued renewable energy policies that can be broadly categorized as either technology-driven policies or technology-agnostic polices. Technology-driven policies are well-situated to target market barriers and historical subsidizations but are hindered by limited flexibility and cost constraints. Conversely, technology-agnostic policies are often more immediately actionable but contain hidden externalities. While the best solution is likely a matter of circumstance and opinion, it is critical that policymakers contemplate the implications behind these policy choices. These implications could determine whether electrification is a key part of the solution to global climate change or a deeply aggravating factor.

description: The present work deals with an interacting dark energy model in the framework of f(T) cosmology. A cosmologically viable form of f(T) is chosen (T is the torsion scalar in teleparallelism) in the background of flat homogeneous and isotropic Friedmann-Robertson-Walker (FRW) space-time model of the universe. The matter content of the universe is chosen as dust interacting with minimally coupled scalar field. The evolution equations are reduced to an autonomous system of ordinary differential equations by suitable transformation of variables. The nature of critical points are analyzed by evaluating the eigenvalues of the linearized Jacobi matrix and stable attractors are examined from the point of view of cosmology. Finally, both classical and quantum stability of the model have been discussed.

Performance evaluation of an emergency call center: tropical polynomial systems applied to timed Petri nets

description: We analyze a timed Petri net model of an emergency call center which processes calls with different levels of priority. The counter variables of the Petri net represent the cumulated number of events as a function of time. We show that these variables are determined by a piecewise linear dynamical system. We also prove that computing the stationary regimes of the associated fluid dynamics reduces to solving a polynomial system over a tropical (min-plus) semifield of germs. This leads to explicit formulæ expressing the throughput of the fluid system as a piecewise linear function of the resources, revealing the existence of different congestion phases. Numerical experiments show that the analysis of the fluid dynamics yields a good approximation of the real throughput.

description: Here we report experimental results on the fluctuations of injected power in confined turbulence. Specifically, we have studied a von Kármán swirling flow with constant external torque applied to the stirrers. Two experiments were performed at nearly equal Reynolds numbers, in geometrically similar experimental setups. Air was utilized in one of them and water in the other. With air, it was found that the probability density function of power fluctuations is strongly asymmetric, while with water, it is nearly Gaussian. This suggests that the outcome of a big change of the fluid density in the flow-stirrer interaction is not simply a change in the amplitude of stirrers' response. In the case of water, with a density roughly 830 times greater than air density, the coupling between the flow and the stirrers is stronger, so that they follow more closely the fluctuations of the average rotation of the nearby flow. When the fluid is air, the coupling is much weaker. The result is not just a smaller response of the stirrers to the torque exerted by the flow; the PDF of the injected power becomes strongly asymmetric and its spectrum acquires a broad region that scales as $f^{-2}$. Thus, the asymmetry of the probability density functions of torque or angular speed could be related to the inability of the stirrers to respond to flow stresses. This happens, for instance, when the torque exerted by the flow is weak, due to small fluid density, or when the stirrers' moment of inertia is large. Moreover, a correlation analysis reveals that the features of the energy transfer dynamics with water are qualitatively and quantitatively different to what is observed with air as working fluid.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: There is limited evidence concerning effective concussion education. Objective: The study purpose was to evaluate the effectiveness of a theory-driven, concussion-specific education platform. Participants: 38 college-aged recreational athletes. Methods: The study was a single blind randomized control trial. Participants completed a survey assessing concussion knowledge, attitudes, perceived norms, and behavioral intentions pre- and post-intervention. Intervention arms included: an interactive concussion education platform with a concussion education sheet and a concussion education sheet with a sham intervention. A general linear mixed model was used to identify the effect of arm and time (pre-post intervention) on outcome variables.  Results: Preliminary analysis included 38 participants. There were no significant interactions of arm by time. Concussion-related attitudes (p<0.001) and perceived norms (p=0.014) were significantly higher at post-intervention than pre-intervention. Conclusion: The results of this study suggest current education content, provided with supplemental information, may improve attitudes and perceived norms.

Both models include a gauge-fixing term and a power-law potential. A dynamical system is formulated and it is found that one of the critical points, for each model, corresponds to inflation, the origin of these critical points being the respective gauge-fixing terms. The conditions for the existence of an inflationary era which lasts for at least 60 efolds are studied.

While all systems show essentially the same type of thermomechanical response-irrespective of their particular structural details-the magnitude of this response is shown to be a function of AI and MII cation radii, as well as the molecular anisotropy of AI. Flexibility is maximised for large MII and small AI, while the shape of AI has implications for the direction of framework hingeing.

description: Statistical mediation analysis is used to uncover intermediate variables, known as mediators [M], that explain how a treatment [X] changes an outcome [Y]. Often, researchers examine whether baseline levels of M and Y moderate the effect of X on posttest M or Y. However, there is limited guidance on how to estimate baseline-by-treatment interaction (BTI) effects when M and Y are latent variables, which entails the estimation of latent interaction effects. In this paper, we discuss two general approaches for estimating latent BTI effects in mediation analysis: using structural models or scoring latent variables prior to estimating observed BTIs and correcting for unreliability. We present simulation results describing bias, power, type 1 error rates, and interval coverage of the latent BTIs and mediated effects estimated using these approaches. These methods are also illustrated with an applied example. R and Mplus syntax are provided to facilitate the implementation of these approaches.

description: Measurement invariance (MI) describes the equivalence of a construct across groups. To be able to meaningfully compare latent factor means between groups, it is crucial to establish MI. Although methods exist that test for MI, these methods do not perform well when many groups have to be compared or when there are no hypotheses about them. We suggest a method called Exploratory Factor Analysis Trees (EFA trees) that are an extension to SEM trees. EFA trees combine EFA with a recursive partitioning algorithm that can uncover non-invariant subgroups in a data-driven manner. An EFA is estimated and then tested for parameter instability on multiple covariates (e.g., age, education, etc.) by a decision tree based method. Our goal is to provide a method with which MI can be addressed in the earliest stages of questionnaire development or prior to analyses between groups. We show how EFA trees can be implemented in the software R using lavaan and partykit. In a simulation, we demonstrate the ability of EFA trees to detect a lack of MI under various conditions. Our online material contains a template script that can be used to apply EFA trees on one’s own questionnaire data. Limitations and future research ideas are discussed.

description: This paper reports on a theoretical analysis of the rich variety of spatio-temporal patterns observed recently in inclined layer convection at medium Prandtl number when varying the inclination angle $γ$ and the Rayleigh number $R$. The present numerical investigation of the inclined layer convection system is based on the standard Oberbeck-Boussinesq equations. The patterns are shown to originate from a complicated competition of buoyancy-driven and shear-flow driven pattern forming mechanisms. The former are expressed as \rm{longitudinal} convection rolls with their axes oriented parallel to the incline, the latter as perpendicular \rm{transverse} rolls. Along with conventional methods to study roll patterns and their stability, we employ direct numerical simulations in large spatial domains, comparable with the experimental ones. As a result, we determine the phase diagram of the characteristic complex 3D convection patterns above onset of convection in the $γ-R$ plane, and find that it compares very well with the experiments. In particular we demonstrate that interactions of specific Fourier modes, characterized by a resonant interaction of their wavevectors in the layer plane, are key to understanding the pattern morphologies.

description: The Navier-Stokes equations are paradigmatic equations describing hydrodynamics of an interacting system with microscopic interactions encoded in transport coefficients. In this work we show how the Navier-Stokes equations arise from the microscopic dynamics of nearly integrable $1d$ quantum many-body systems. We build upon the recently developed hydrodynamics of integrable models to study the effective Boltzmann equation with collision integral taking into account the non-integrable interactions. We compute the transport coefficients and find that the resulting Navier-Stokes equations have two regimes, which differ in the viscous properties of the fluid. We illustrate the method by computing the transport coefficients for an experimentally relevant case of coupled $1d$ cold-atomic gases.

A Possible Mechanism for Overcoming the Electrostatic Barrier Against Dust Growth in Protoplanetary disks

description: The coagulation of dust particles under the conditions in protoplanetary disks is investigated. The study focuses on the repulsive electrostatic barrier against growth of charged dust grains. Taking into account the photoelectric effect leads to the appearance of a layer at intermediate heights where the dust has a close to zero charge, enabling the dust grains to grow efficiently. An increase in the coagulation rate comes about not only due to the lowering of the Coulomb barrier, but also because of the electrostatic attraction between grains of opposite charge due to the non-zero dispersion of the near-zero charge. Depending on the efficiency of mixing in the disk, the acceleration of the evolution of the dust in this layer could be important, both in the quasi-stationary stage of the disk evolution and during its dispersal.
Do subconcussive impacts cause balance deficits in athletes?
Creators: name: Booth, Matthew Stephen
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: We systematically identified the effects of acute and cumulative subconcussive head impact exposure on balance in athletes. We searched eleven indexed scientific databases for articles pertaining to subconcussive impacts and outcomes related to balance. Eligible articles were reviewed and evaluated with three quality assessment tools. Articles (n=26,117) were screened and 21 met inclusion criteria. Articles demonstrated no conclusive evidence that balance/postural control is affected following acute and cumulative head impact exposure. We concluded the following given the reviewed evidence: 1) Balance/postural deficits are not seen following acute HIE but may be apparent following single-season exposure in collision, 2) generally low budget tests such as the BESS are similar to tests with advanced metrics, which is beneficial for clinicians who do not have the resources necessary for force plates and 3) consistent experimental protocols should be developed based on each balance/postural control outcome measure to allow for greater generalizability of results.

description: Rescaled Mellin-type transforms of the exponential functional of the Bourgade-Kuan-Rodgers statistic of Riemann zeroes are conjecturally related to the distribution of the total mass of the limit lognormal stochastic measure of Mandelbrot-Bacry-Muzy. The conjecture implies that a non-trivial, log-infinitely divisible probability distribution is associated with Riemann zeroes. For application, integral moments, covariance structure, multiscaling spectrum, and asymptotics associated with the exponential functional are computed in closed form using the known meromorphic extension of the Selberg integral.

description: ABSTRACT      Judith A. Beck: Student Wellness: Stress Among Undergraduate Dental Hygiene Students      (Under the direction of Ceib Phillips)      Purpose: The purpose of this study is to assess stress among dental hygiene students in two intensive programs.      Methods:  All dental hygiene (DH) students at the University of North Carolina at Chapel Hill, Adam’s School of Dentistry (UNC ASoD) and a North Carolina community college (NCCC) were provided an anonymous Qualtrics survey link. Screening for depression (PHQ-9), anxiety (GAD-7), and a modified version of the Medical Outcomes Study Social Support Survey were included. Chi-square and Mantel Haenszel statistics were used in the analysis depending on scale of measurement.      Results:  Participants (n=136) included 69 DH students from UNC ASoD and 54 DH students from a NCCC. There were no statistically significant differences between respondents for demographics or personal lifestyles (all p>0.05). There was a statistically significant difference in the proportion of students reporting moderately-severe or severe anxiety (p=0.007) with 56% of NCCC respondents and 36% of UNC ASoD reporting these anxiety levels. There was no statistically significant difference in depression (P=0.07). Overall, 42.6% reported moderately-severe or severe depression. Of all respondents, 7.8%  reported suicidal ideation in the last 12 months.        Conclusion:  The proportion of dental hygiene students enrolled in these two programs were substantially higher than the clinical cut points for mental and emotional concerns and suicidal ideation.

description: Radiation-induced pulmonary fibrosis (RIPF) is one of the serious complications and fatal disorder in radiotherapy of thoracic tumors. Radiation damage is to a large extent caused by overproduction of reactive oxygen species (ROS), which is crucial for tumor killing but harmful to induce lung injury and RIPF. Although pirfenidone was approved for the treatment of idiopathic pulmonary fibrosis, its inhibitory effect on ROS is limited. Hence, using 10-carboxyl-pirfenidone and 1,10-phenanthroline as the ligand, a nanoscale complex with Cerium(III) was designed (NPs Ce(phen)Pirf3) in the present study. Using the irradiation fibrosis model of RLE-6TN cell strain and C57 mice, the complex significantly improved ROS scavenging and alleviated radiation-induced lung pathological changes, showed improvement in lung function during 4~16 weeks, and regulated the expression of N-cadherin, E-cadherin, α-SMA, and TGF-β1 to alleviate RIPF. Cerium(III) and 1,10-phenanthroline endow NPs Ce(phen)Pirf3 with blue fluorescence, and the nanostructures enable NPs Ce(phen)Pirf3 sustained release for 4h. In addition, benefiting from Ce-containing, the role of NPs Ce(phen)Pirf3 in reducing the growth of two typical thoracic tumor models (A549 and 4T1) was investigated. Taken together, our research highlighted the differential effect of NPs Ce(phen)Pirf3 on RIPF treatment and tumor destruction, which would provide a new promise for radioprotection.

description: Let $\mathcal A\subset\mathbb P^{k-1}$ be a rank $k$ arrangement of $n$ hyperplanes, with the property that any $k$ of the defining linear forms are linearly independent (i.e., $\mathcal A$ is called $k-$generic). We show that for any $j=0,\ldots,k-2$, the subspace arrangement with defining ideal generated by the $(n-j)-$fold products of the defining linear forms of $\mathcal A$ is a set-theoretic complete intersection, which is equivalent to saying that star configurations have this property.
description: 5 pages. In this version we present an update with an example answering negatively the question asked previously whether or not, for ANY hyperplane arrangement, all the ideals generated by a-fold products of the defining linear forms are set-theoretic complete intersections
