description: Classical thermodynamics is unrivalled in its range of applications and relevance to everyday life. It enables a description of complex systems, made up of microscopic particles, in terms of a small number of macroscopic quantities, such as work and entropy. As systems get ever smaller, fluctuations of these quantities become increasingly relevant, prompting the development of stochastic thermodynamics. Recently we have seen a surge of interest in exploring the quantum regime, where the origin of fluctuations is quantum rather than thermal. Many questions, such as the role of entanglement and the emergence of thermalisation, lie wide open. Answering these questions may lead to the development of quantum heat engines and refrigerators, as well as to vitally needed simple descriptions of quantum many-body systems.

description: We report on measurements of the differential cross section $dσ/dΩ$ in the energy region of $\sqrt{s}$ = 2.5-2.9 GeV of the reaction $pp \to \{pp\}_s π^0$ where $\{pp\}_s$ is a $^1\!S_0$ proton pair. The experiment has been performed with the ANKE spectrometer at COSY-Jülich. The data reveal a peak in the energy dependence of the forward $\{pp\}_s$ differential cross section at the energy $\sqrt{s}$ = 2.65 GeV with the width $Γ$ = 0.26 GeV, and also the cross section slope changes its sign in the region of the observed peak. This is an indication for the excitation of a new $D(2650)$ resonant state, that may be a dibaryon resonance system consisting of two excited baryons $Δ(1232)$ and $N^*(1440)$.

description: In a changing climate, a key role may be played by the response of convective-type cloud and precipitation to temperature changes. Yet, it is unclear if precipitation intensities will increase mainly due to modified thermodynamic forcing or due to stronger convective dynamics. In gradual self-organization, convective events produce highest intensities late in the day. Tracking rain cells throughout their life cycles, we find that interacting events respond strongly to changes in boundary conditions. Conversely, events without interaction remain unaffected. Increased surface temperature indeed leads to more interaction and higher precipitation extremes. However, a similar intensification occurs when leaving temperature unchanged but simply granting more time for self-organization.Our study implies that the convective field as a whole acquires a memory of past precipitation and inter-cloud dynamics, driving extremes. Our results implicate that the dynamical interaction between convective clouds must be incorporated in global climate models to describe convective extremes and the diurnal cycle more realistically.

Year: 2006

description: Background: Pediatric preventive health services, including screening, counseling, chemoprophylaxis, and immunization, are an essential part of health care for children; these services prevent disease and injury and promote the health of children. However, despite the widely recognized importance of pediatric preventive health services, the rate of delivery of many of these services remains low. Objectives: To examine the magnitude and extent of the problem oflow delivery rates of recommended pediatric preventive health services and to evaluate policy alternatives to address this problem. Methods: I examined the extent to which all U.S. children 0-5 years old receive preventive health services recommended by the AAP, Bright Futures, AAFP, USPSTF, and CDC. I focused on the following policy alternatives to increase delivery rates of recommended pediatric preventive health services: increased Medicaid and/or SCHIP coverage of uninsured children, patient reminder and recall systems, increased provider reimbursement for preventive health services, provider assessment and feedback, and provider reminder systems. I evaluated each of these policy alternatives using the following criteria: effectiveness, efficiency, equity, timeliness, patient-centeredness, ease of implementation, and political acceptability. I gathered data for the evaluation through a literature review of the MEDLINE database and the Cochrane Library. Results: Increased Medicaid and/or SCHIP coverage was highly equitable and moderately politically acceptable but had low effectiveness. Increased provider reimbursement for preventive health services was moderately effective and highly efficient but had low political acceptability. Patient reminder and recall systems, provider assessment and feedback, and provider reminder systems were highly effective, efficient, and politically acceptable. Conclusions: A synthesis of patient reminder and recall systems, provider assessment and feedback, and provider reminder systems is recommended to increase the delivery of preventive health services for U.S. children 0-5 years old.
Threat messages in Hate speech on Social media

Subjects: subject: Social and Behavioral Sciences

description: Empirical data suggests that social media platforms such as Twitter are strategically used by supporters of extremist ideologies to promote hate speech and facilitate radicalization processes, but underlying psychological mechanisms remain unclear. What is more, the impact of hate speech messages on Twitter users has to the best of my knowledge not yet been examined. The present project aims to provide a more nuanced picture of the content and impact of tweets with hate speech content on their readers by detecting systematic patterns. The project examines the following research questions: 1. Does hate speech on German twitter contain messages paint immigrants and Muslims as a symbolic, realistic or safety threat? 2. How do these threat messages differ with regards to their content and wording? 3. Does the prevalence of threat messages in hate speech predict readers’ reactions in form of likes? The study will use two data subsets from the POLLY dataset which together contain over 40.000 German tweets collected in 2017 and wereas made publicly available for academic purposes by the researchers Jaki & De Smedt and has been anonymized in line with the EU’s new General Data Protection Regulation. Drawing on the concepts of Integrated Threat Theory, I expect content on German twitter, which is classified as hate speech, to contain significantly more threat perceptions than tweets which are not classified as hate speech. I also expect that the impact of these messages is reflected in form of an increased number of likes in comparison with tweet messages that are not classified as hate speech.
Military Veterans as a Health Disparity Population: Is Service a Determinant of Health?
Creators: name: Huse, Lindsay
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Millions of military Veterans live in the United States (U.S.), with service spanning decades of global conflicts. Despite rigorous health requirements while on active duty and access to one of the largest health systems in the U.S., Veterans report poorer overall health and experience a number of risk factors that can cause adverse health outcomes. Health disparities occur within the Veteran population, similar to those experienced within civilian populations. However, Veterans can also be considered a distinct group that suffers health inequities when compared to their civilian counterparts, with military service being a future determinant of health. As such, this paper will explore Veteran disparities, identify risk factors leading to them, and describe existing programs to address them. Research, policy, and program recommendations to further address Veterans' health inequities are included. Key words: Veterans, Health disparity, Access to care

description: We revisit the main HI-to-stellar mass ratio (gas fraction) scaling relations, taking advantage of the HI spectral stacking technique to understand the dependence of gas content on the structural and star formation properties of nearby galaxies. This work uses a volume-limited, multi-wavelength sample of ~25,000 galaxies, selected according to stellar mass (10^9 M_sol < M_* < 10^11.5 M_sol) and redshift (0.02 < z < 0.05) from the Sloan Digital Sky Survey, and with HI data from the Arecibo Legacy Fast ALFA survey. We bin according to multiple parameters of galaxies spanning the full gas-poor to -rich regime in order to disentangle the dominance of different components and processes in influencing gas content. For the first time, we show that the scaling relations of gas fraction with stellar mass and stellar surface density are primarily driven by a combination of the underlying galaxy bimodality in specific star formation rate and the integrated Kennicutt-Schmidt law. Finally, we produce tentative evidence that the timescales of HI depletion are dependent upon galaxy mass and structure, at fixed specific star formation rate.

Dynamical Friction in fuzzy dark matter: circular orbits

description: We investigate the dynamical friction (DF) acting on circularly-moving perturbers in fuzzy dark matter (FDM) backgrounds. After condensation, FDM is described by a single wave function satisfying a Schrödinger-Poisson equation. An equivalent, hydrodynamic formulation can be obtained through the Madelung transform. Here, we consider both descriptions and restrict our analysis to linear response theory. We take advantage of the hydrodynamic formulation to derive a fully analytic solution to the DF in steady-state and for a finite time perturbation. We compare our prediction to a numerical implementation of the wave approach that includes a non-vanishing FDM velocity dispersion $σ$. Our solution is valid for both a single and a binary perturber in circular motion as long as $σ$ does not significantly exceed the orbital speed $v_\text{circ}$. While the short-distance Coulomb divergence of the (supersonic) gaseous DF is no longer present, DF in the FDM case exhibits an infrared divergence which stems from the (also) diffusive nature of the Schrödinger equation. Our analysis of the finite time perturbation case reveals that the density wake diffuses through the FDM medium until it reaches its outer boundary. Once this transient regime is over, both the radial and tangential DF oscillate about the steady-state solution with an exponentially decaying envelope. Steady-state is thus never achieved. We use our results to revisit the DF decay timescales of the 5 Fornax globular clusters. We also point out that the inspiral of compact binary may stall because the DF torque about the binary center-of-mass sometimes flips sign to become a thrust rather than a drag (abridged).

Thermalization and dynamics in the single impurity Anderson model

description: We analyze the process of thermalization, dynamics and the eigenstate thermalization hypothesis (ETH) for the single impurity Anderson model, focusing on the Kondo regime. For this we construct the complete eigenbasis of the Hamiltonian using the numerical renormalization group (NRG) method in the language of the matrix product states. It is a peculiarity of the NRG that while the Wilson chain is supposed to describe a macroscopic bath, very few single particle excitations already suffice to essentially thermalize the impurity system at finite temperature, which amounts to having added a macroscopic amount of energy. Thus given an initial state of the system such as the ground state together with microscopic excitations, we calculate the spectral function of the impurity using the microcanonical and diagonal and grand canonical ensembles. By adding or removing particles at a certain Wilson energy shell on top of the ground state, we find qualitative agreement between the spectral functions calculated for different ensembles. This indicates that the system thermalizes in the long-time limit, and can be described by an appropriate statistical-mechanical ensemble. Moreover, by calculating the impurity spectral density at the Fermi level and the dot occupancy for energy eigenstates relevant for microcanonical ensemble, we find good support for ETH. The ultimate mechanism responsible for this effective thermalization within the NRG can be identified as Anderson orthogonality: the more charge that needs to flow to or from infinity after applying a local excitation within the Wilson chain, the more the system looks thermal afterwards at an increased temperature. For the same reason, however, thermalization fails if charge rearrangement after the excitation remains mostly local.

description: Tasked by the government through the Deficit Reduction Act (DRA) of2005 to transform Medicare from a passive payer into an active purchaser of care, the Centers for Medicare and Medicaid Services (CMS) has been investigating methods of incorporating payfor- performance (P4P) models into Medicare. When CMS published its Value-Based Purchasing (VBP) proposal for overhaul of Medicare inpatient reimbursements in November of2007, the proponents and skeptics alike had much to say about the new plan. Some approved strongly. Some disapproved vehemently, while most others were somewhere in between. Certain themes surrounding VBP continue to surface. What do stakeholders believe are the key issues surrounding P4P and the VBP proposal? How and why do payers and providers differ in their support for VBP? Do all stakeholders find common ground in the VBP, or are some aspects ofVBP particularly agreeable or distasteful? Has CMS structured the VBP proposal in ways that will maximize VBP's chances of success? Does VBP pose a threat to small and rural hospitals already struggling to stay afloat? Does the literature support CMS's claim that VBP can improve quality of health care while reducing costs? In order to address these questions, I performed a systematic review of the literature, reviewed media accounts, interviewed key stakeholders, and studied the stakeholder responses provided to the Senate Finance Committee Roundtable on Hospital Value-Based Purchasing. I found that payer groups were eager to introduce VBP, while the hospital and professional groups were concerned that VBP threatened their own interests, especially regarding budget neutrality. However, I also found some important items of consensus as well that could lay the groundwork for the future ofVBP.

Outcomes of Hip Fractures at Teaching Hospitals Versus Non-Teaching Hospitals
Creators: name: Schreier, Star L., MD
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: Hip fractures in adults are associated with a large burden of suffering in the United States and are a major focus of various advocacy groups, professional organizations and government agencies. Strategies for prevention of hip fractures include primary prevention of osteoporosis, secondary prevention of fractures in patients with asymptomatic osteoporosis, tertiary prevention of complications in patients with hip fractures, and quarternary prevention of long-term disability from hip fracture. As a tertiary prevention option, surgery to repair a hip fracture has many benefits but is still associated with negative outcomes. This research establishes the evidence base and proposes a secondary analysis for determining whether patients treated for hip fracture at teaching hospitals experience fewer negative outcomes than do patients treated at non-teaching hospitals. A systematic review of the literature does not permit the drawing of firm conclusions about teaching hospital status, but a secondary analysis of data from the Nationwide Inpatient Sample (NIS) database could advance our understanding of the context of hip fracture outcomes. A study sample, based on patients with ICD-9 diagnosis codes for hip fracture, can be drawn from admissions represented in the NIS database, and outcomes including rates of mortality, rates of various postoperative complications, lengths of stay, cost, and discharge dispositions can be correlated with forms of treatment and teaching hospital status.

TED, Europarl, and OPUS parallel text corpora were used as the basis for training of language models, for developmental tuning and testing of the translation system. We also conducted experiments involving part of speech tagging, compound splitting, linear language model interpolation, TrueCasing and morphosyntactic analysis. We evaluated the effects of variety of data preparations on the translation results using the BLEU, NIST, METEOR and TER metrics and tried to give answer which metric is most suitable for PL-EN language pair.

Excitation spectra of strongly interacting bosons in the flat-band Lieb lattice

Year: 2022
Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: The strongly correlated bosons in flat band systems are an excellent platform to study a wide range of quantum phenomena. Such systems can be realized in optical lattices filled with ultracold atomic gases. In this paper we study the Bose-Hubbard model in the Lieb lattice by means of the time-dependent Gutzwiller mean-field approach. We find that in the Mott insulator phase the excitation modes are gapped and display purely particle or purely hole character, while in the superfluid phase the excitation spectrum is gapless. The geometry of the Lieb lattice leads to a non-uniform order parameter and non-uniform oscillation energy in the ground state. This results in additional anti-crossings between dispersive bands in the excitation spectra, while the flat bands remain insensitive to this effect. We analyze the oscillations of the order parameter on the sublattices as well as the particle-hole character of the excitations. For certain model parameters we find simultaneous pure phase and pure amplitude oscillations within the same mode, separated between the sublattices. Also, we propose a simple method to differentiate between the hole- and particle superfluid regions in the Lieb lattice by in-situ measurement of the atom population on the sublattices.

description: The arise of disagreement is an emergent phenomenon that can be observed within a growing social group and, beyond a certain threshold, can lead to group fragmentation. To better understand how disagreement emerges, we introduce an analytically tractable model of group formation where individuals have multidimensional binary opinions and the group grows through a noisy homophily principle, i.e., like-minded individuals attract each other with exceptions occurring with some small probability. Assuming that the level of disagreement is correlated with the number of different opinions coexisting within the group, we find analytically and numerically that in growing groups disagreement emerges spontaneously regardless of how small the noise in the system is. Moreover, for groups of infinite size, fragmentation is inevitable. We also show that the model outcomes are robust under different group growth mechanisms.

description: Accurate and precise measurements of the Hubble constant are critical for testing our current standard cosmological model and revealing possibly new physics. With Hubble Space Telescope (HST) imaging, each strong gravitational lens system with measured time delays can allow one to determine the Hubble constant with an uncertainty of $\sim 7\%$. Since HST will not last forever, we explore adaptive-optics (AO) imaging as an alternative that can provide higher angular resolution than HST imaging but has a less stable point spread function (PSF) due to atmospheric distortion. To make AO imaging useful for time-delay-lens cosmography, we develop a method to extract the unknown PSF directly from the imaging of strongly lensed quasars. In a blind test with two mock data sets created with different PSFs, we are able to recover the important cosmological parameters (time-delay distance, external shear, lens mass profile slope, and total Einstein radius). Our analysis of the Keck AO image of the strong lens system RXJ1131-1231 shows that the important parameters for cosmography agree with those based on HST imaging and modeling within 1-$σ$ uncertainties. Most importantly, the constraint on the model time-delay distance by using AO imaging with $0.045"$resolution is tighter by $\sim 50\%$ than the constraint of time-delay distance by using HST imaging with $0.09"$when a power-law mass distribution for the lens system is adopted. Our PSF reconstruction technique is generic and applicable to data sets that have multiple nearby point sources, enabling scientific studies that require high-precision models of the PSF.

The central element is a displacement sensor with an integrated electromagnetic actuator known as a BOSEM and its readout and drive electronics required to integrate them into LIGO's control and data system. In this paper we report on improvements to the sensors and testing procedures undertaken to meet enhanced performance requirements set out by the A+ upgrade to the detectors. The best devices reach a noise level of $4.5\times 10^{-11}{\rm m}/\sqrt{\rm Hz}$ at a measurement frequency of 1 Hz.

description: We present an updated version of the 2015-Atlas of Nuclear Isomers \cite{jain2015}, compiling and evaluating experimental data for the isomers with half-life $\ge 10$ $\it{ns}$, together with their spectroscopic properties such as excitation-energies, half-lives, decay modes, spins and parities, energies and multipolarities of isomeric transitions, along with the relevant original references in literature. The current version of Atlas presents many re-evaluated half-lives as compared to the 2015 edition, where values were referred to Nuclear Data Sheets publications, when no new data existed. The ENSDF database \cite{Ensdf}, together with the XUNDL \cite{Xundl} and the NUBASE2020 \cite{Kondev2021} databases have been consulted for completeness, yet, data from original papers from journals were considered in the present evaluation, and the NSR bibliographic database \cite{Nsr} has been searched to ensure that this work is as complete and current as possible. Several useful systematic features of nuclear isomers covered in this Atlas have been discussed. Literature cutoff date for the extraction of data is October 31, 2022.

description: A Lorentzian manifold endowed with a time function, $τ$, can be converted into a metric space using the null distance, $\hat{d}_τ$, defined by Sormani and Vega. We show that if the time function is a proper regular cosmological time function as studied by Andersson, Galloway and Howard, and also by Wald and Yip, or if, more generally, it satisfies the anti-Lipschitz condition of Chruściel, Grant and Minguzzi, then the causal structure is encoded by the null distance in the following sense: $$ \hat{d}_τ(p,q)=τ(q)-τ(p) \iff q \textrm{ lies in the causal future of } p. $$ As a consequence, in dimension $n+1$, $n\ge 2$, we prove that if there is a bijective map between two such spacetimes, $F: M_1\to M_2$, which preserves the cosmological time function, $ τ_2(F(p))= τ_1(p)$ for any $ p \in M_1$, and preserves the null distance, $\hat{d}_{τ_2}(F(p),F(q))=\hat{d}_{τ_1}(p,q)$ for any $p,q\in M_1$, then there is a Lorentzian isometry between them, $F_*g_1=g_2$. This yields a canonical procedure allowing us to convert such spacetimes into unique metric spaces with causal structures and time functions. This will be applied in our upcoming work to define Spacetime Intrinsic Flat Convergence.

Probing interactions between Rydberg atoms with large electric dipole moments in amplitude modulated electric fields

description: Dipole-dipole interactions between helium atoms in Rydberg-Stark states with principal quantum number $n=53$ and approximately linear Stark energy shifts, resulting from induced electric dipole moments of approximately 7900 D, have been investigated experimentally. The experiments were performed in pulsed supersonic metastable helium beams, with particle number densities of up to $\sim10^9$ cm$^{-3}$. In the presence of amplitude-modulated, radio-frequency electric fields, changes in the spectral intensity distributions associated with the transitions to these states that are attributed to dipole-dipole interactions within the ensembles of excited atoms have been observed. The experimental results are in excellent agreement with calculations of the Rydberg energy level structure carried out using Floquet methods, and excitations shared by up to 4 atoms. The use of these Rydberg-Stark states as sensors for non-resonant broadband radio-frequency electrical noise is also discussed.

Quantifying the Effect of Pill-taking on Quality of Life
Creators: name: Hutchins, Robert

description: Utility measures are used in cost-effectiveness studies to represent the effect a given outcome or intervention has on quality of life. Pills are common interventions used to try to reduce the risk of an adverse health outcome. The utility value for taking pills is often estimated or assumed to be 1.0, suggesting no effect on quality of life, but I wondered whether any studies had been published that quantified this utility value. This master’s paper has two goals. In the systematic review portion, I searched for published articles that quantified the utility of taking pills for preventive purposes. In the original research portion, I report the results of a study that quantified the utility value of taking pills to prevent an adverse health outcome. For the review, I systematically searched PUBMED using strategically selected keywords. This strategy was supplemented with a search of the Cochrane database, a hand search of bibliographies, and questioning of experts. Studies that calculated a utility value were included. I expanded the inclusion criteria to any article that cited a utility value for pill-taking for preventive purposes in adults. In the original research, we invited healthcare system employees to participate in an online survey about taking pills. We calculated mean utility values for taking pills and compared utility values across several demographic characteristics and by numeracy level. I found two published articles that quantified the utility value of taking aspirin and warfarin. I found a total of nineteen additional published articles that cite a utility value for taking pills for preventive purposes. All these values ranged from 0.95 – 1.0, depending on the type of pills. Through our original research project involving 708 adults, we found that the average utility value for taking one pill per day is 0.997. This value did not vary significantly by age, sex, race, education level, income level, or number of pills taken per day. Those with low numeracy level tended to have slightly lower utility values.

Immunoglobulin G and Immunoglobulin M Seronegative Q Fever: A Hypothesis for Gulf War Veterans' Illnesses
Creators: name: Chagaris, Michael
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: This article presents Q fever as a credible hypothesis for Gulf War Veterans' Illnesses (GWVIs) and as a possible etiology for prevalent symptomologies affecting currently serving service members. Q fever is caused by the bacteria Coxiella burnetii, which is endemic throughout the Middle East. Q fever may manifest in many forms of widely varying and often inconstant symptoms. Due to false-negative interpretations in current and past diagnostic testing, Q fever has not received appropriate consideration as a possible causative agent for medically unexplained veterans' illnesses. Review of current literature invites us to consider that a form of Q fever, involving an incomplete immune response, is a potential cause of these debilitating illnesses. This article presents the hypothesis that C. burnetii infection coincidental to exposures suppressing antibody-specific immune response results in infection mediated by immunoglobulin D (IgD). Literature indicates that successful treatment for this form of Q fever requires the concurrent administration of doxycycline and hydroxychloroquine.
