description: The verification of quantum devices is an important aspect of quantum information, especially with the emergence of more advanced experimental implementations of computation and secure communication. Within this, the theory of device-independent robust self-testing via Bell tests has reached a level of maturity now that many quantum states and measurements can be verified without direct access to the quantum systems: interaction with the devices is solely classical. However, the requirements for this robust level of verification are daunting and require high levels of experimental accuracy. In this paper we discuss the possibility of self-testing where we have direct access to part of the quantum device. This motivates the study of self-testing via EPR-steering, an intermediate form of entanglement verification between full state tomography and a Bell test. Quantum non-locality implies EPR-steering so results in the former can apply in the latter, but we ask what advantages may be gleaned from the latter over the former given that one can do partial state tomography. We show in the case of self-testing a maximally entangled two-qubit state, or ebit, EPR-steering allows for simpler analysis and better error tolerance than in the case of full device-independence. On the other hand, this improvement is only a constant improvement and (up to constants) is the best one can hope for. Finally, we indicate that the main advantage in self-testing based on EPR-steering could be in the case of self-testing multi-partite quantum states and measurements. For example, it may be easier to establish a tensor product structure for a particular party's Hilbert space even if we do not have access to their part of the global quantum system.

Thermodynamics of weakly coupled Falicov-Kimball chains from renormalization-group theory

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: The linear perturbation renormalization group is used to study spinless two-band fermion chains at half-filling. The model consists of two species of spinless fermions, namely localized f and extended p, and it takes into account the following: the kinetic energy of fermions p, the on-site Coulomb repulsion V between p and f fermions, chemical potentials μp and μf adjusted in such a way that the average of the site occupation = 1, and a weak interchain hopping tx . The average occupation number, the specific heat, and the correlation functions are studied as functions of temperature. For a single chain the occupation number is a smooth function of T and the specific heat displays two maxima. The weak interchain hopping triggers a discontinuity in the occupation number of fermions as a function of temperature. A long-standing controversy on whether the Falicov-Kimball model can describe a discontinuous transition of nf is also addressed.

description: Dynamic nucleation of dislocations caused by a stress front ('shock') of amplitude $σ_{\rm a}$ moving with speed $V$ is investigated by solving numerically the Dynamic Peierls Equation with an efficient method. Speed $V$ and amplitude $σ_{\rm a}$ are considered as independent variables, with $V$ possibly exceeding the longitudinal wavespeed $c_{\rm L}$. Various reactions between dislocations take place such as scattering, dislocation-pair nucleation, annihilation, and crossing. Pairs of edge dislocation are always nucleated with speed $v\gtrsim c_{\rm L}$ (and likewise for screws with $c_{\rm L}$ replaced by $c_{\rm S}$, the shear wavespeed). The plastic wave exhibits self-organization, forming distinct `bulk' and `front' zones. Nucleations occur either within the bulk or at the zone interface, depending on the value of $V$. The front zone accumulates dislocations that are expelled from the bulk or from the interface. In each zone, dislocation speeds and densities are measured as functions of simulation parameters. The densities exhibit a scaling behavior with stress, given by $((σ_a/σ_{\rm th})^2-1)^β$, where $σ_{\rm th}$ represents the nucleation threshold and $0<β<1$.

description: Ferrimagnets have received renewed attention as a promising platform for spintronic applications. Of particular interest is the Mn4N from the $ε$-phase of the manganese nitride as an emergent rare-earth-free spintronic material due to its perpendicular magnetic anisotropy, small saturation magnetization, high thermal stability, and large domain wall velocity. We have achieved high-quality (001)-ordered Mn$_{4}$N thin film by sputtering Mn onto $η$-phase Mn$_{3}$N$_{2}$ seed layers on Si substrates. As the deposited Mn thickness varies, nitrogen ion migration across the Mn$_{3}$N$_{2}$/Mn layers leads to a continuous evolution of the layers to Mn$_{3}$N$_{2}$/Mn$_{2}$N/Mn$_{4}$N, Mn$_{2}$N/Mn$_{4}$N, and eventually Mn$_{4}$N alone. The ferrimagnetic Mn$_{4}$N indeed exhibits perpendicular magnetic anisotropy, and forms via a nucleation-and-growth mechanism. The nitrogen ion migration is also manifested in a significant exchange bias, up to 0.3 T at 5 K, due to the interactions between ferrimagnetic Mn$_{4}$N and antiferromagnetic Mn$_{3}$N$_{2}$ and Mn$_{2}$N. These results demonstrate a promising all-nitride magneto-ionic platform with remarkable tunability for device applications.

Vacuum radiation versus shortcuts to adiabaticity

description: The nonadiabatic dynamic of the electromagnetic field triggers photons generation from the quantum vacuum. Shortcuts to adiabaticity, instead, are protocols that mimic the field's adiabatic dynamic in a finite time. Here, we show how the counterdiabatic term of the transitionless tracking algorithm cancels out, exactly, the term responsible for the photon production in the dynamical Casimir effect. This result suggests that the energy of producing photons out of the vacuum is related to the energetic cost of the shortcut. Furthermore, if the system operates under a quantum thermodynamic cycle, we confirm the equivalence between the adiabatic and nonadiabatic work outputs. Finally, our study reveals that identifying these unreported observations can only be possible using the so-called effective Hamiltonian approach.

Examining practice-level factors influencing rate of clinical quality improvement with practice facilitation
Creators: name: Hines, Rachel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: Studies of medical care in the United States consistently show inconsistent quality and access among Americans. In an effort to improve healthcare while decreasing disparities, there has been a push to implement evidence-based practices more consistently in primary care settings. The use of practice facilitators, individuals whose role is to help get guidelines into practice, has become more common in quality improvement interventions. Here, we reviewed the literature on the effectiveness of practice facilitation in controlled trials and also analyzed some of the results of a program – the North Carolina Improving Performance in Practice (IPIP) program – that relies on practice facilitation. Studies, including a recent meta-analysis, support the use of facilitation in diverse clinical settings and for a variety of evidence-based practice. In North Carolina, more patients received guideline-based care and had better outcomes while practices were enrolled in IPIP; this did not appear to generally depend on practice demographics. Rather, the rate of improvement across measures depended on the length of a practice’s enrollment in the program. This rate of change method provides important information about the natural history of improvement in practices but also has many limitations. Future studies should develop better, standardized ways to measure the impact of quality improvement programs like IPIP using data that was collected for providers’ rather than researchers’ purposes.

The Epidemic of Opioid Abuse and Diversion: Public Health Implications, Primary Care Needs and Usage of Prescription Drug Monitoring Databases
Creators: name: Cook, Elizabeth
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: The last two decades have seen a dramatic rise in the abuse, diversion, and overdose rates of opiate medications. This paper will look at the reasons behind the surge, and the concerning statistics about overdoses and deaths resulting from significantly expanded use of these medications. In order to stem the epidemic, three key stakeholders have an opportunity to align interests in decreasing abuse and overdoses. Primary care providers are major prescribers of opiate prescriptions, yet they lack adequate training in chronic pain management, screening for addiction, and counseling patients with opiate addiction. Collaboration between public health organizations and primary care providers working to expand addiction recovery services in the community, as well as to address the underlying socioeconomic determinants of health, will be vital to the interventions. The Prescription Drug Monitoring Database is a technological tool that is utilized to track prescriptions of controlled substances. Improvement in interstate sharing and interoperability with primary care providers' electronic medical records will be needed to ensure widespread usage by providers.

description: Transverse momentum spectra of different particles produced in mid-rapidity interval in lead-lead (Pb-Pb) collisions with different centrality intervals, measured by the ALICE Collaboration at center-of-mass energy per nucleon pair $\sqrt{s_{NN}}=2.76$ TeV, are conformably and approximately described by the Tsallis distribution. The dependences of parameters (effective temperature, entropy index, and normalization factor) on event centrality and particle rest mass are obtained. The source temperature at the kinetic freeze-out is obtained to be the intercept in the linear relation between effective temperature and particle rest mass, while the particle transverse flow velocity is approximately extracted to be the slope in the linear relation between mean transverse momentum and particle rest mass. It is shown that the source temperature increases with increase of particle rest mass, which exhibits an evidence of mass dependent differential kinetic freeze-out scenario or multiple kinetic freeze-out scenario.

photoinduced Hydrogen-Atom-Transfer reaction

description: Hydrogen atom transfer provides straightforward methods to generate open-shell radical intermediates from C-H bonds and offers unique opportunities for green and sustainable synthesis. Visible-light-induced C-H functionalization enabled by HAT is an emerging strategy for substrate activation in photocatalyzed organic synthesis. In recent years, photoinduced HAT reactions have seen substantial development of their versatility, efficiency, and selectivity. However, asymmetric photocatalysis via hydrogen atom transfer has rarely been reported. In the first section, a visible-light-induced asymmetric rearrangement of 3-(2-formylphenyl)-1-pyrazol-1-yl-propenones to benzo-[d]cyclopropa[b]pyranones with up to > 99% ee is introduced, which is catalyzed by a bis-cyclometalated chiral-at-metal rhodium complex (RhS). Mechanistic experiments and DFT calculations support a mechanism whereby the photoexcited catalyst/substrate complex generates triplet excited-state species through photoiduced intersystem crossing, which triggers an intramolecular hydrogen atom transfer subsequent highly stereocontrolled hetero-Diels–Alder reaction. In this reaction scheme, the rhodium catalyst fulfills multiple functions by 1) enabling visible-light π→π* excitation of the catalyst-bound enone substrate, 2) facilitating the hydrogen atom transfer, and 3) providing the asymmetric induction for the hetero-Diels–Alder reaction. In the second section, a visible light driven deracemization of ketones as a new type of deprotonation and asymmetric protonation is demonstrated for the first time, which leads to the formation of chiral carbonyl compounds in an efficient way with high yield (up to 97%) and high enantioselectivity (up to 97%). This new photoinduced deprotonation process is achieved by single electron transfer and subsequent hydrogen atom transfer. A bis-cyclometalated chiral-at-metal rhodium complex (RhInd) is used as the photocatalyst to induce the redox process and is responsible for the asymmetric induction, while the amine acts as the single electron reductant, HAT reagent and proton source. This conceptually simple light-driven strategy of coupling a photoredox deprotonation with a stereocontrolled protonation serves as a blueprint for other deracemizations of ubiquitous carbonyl compounds.
An In-Depth Program Evaluation: Weigh To Wellness, UNC Wellness Center at Meadowmont, 2010

Year: 2010

description: The Centers for Disease Control and Prevention (CDC) characterize American society as “obesogenic”; a society characterized by environments that promote increased food intake, nonhealthful foods, and physical inactivity. (The Centers for Disease Control and Prevention: obesity statistics http://www.cdc.gov/obesity/index.html) Policy changes and environmental initiatives that promote healthy eating, physical activity and nutrition as well as making them accessible, affordable and easy are the best way to combat obesity and reduce the risk factors that are closely associated with it such as diabetes, heart disease and certain cancers. Successful weight loss programs must focus on lifestyle modification, not diet alone. There is some evidence to support that lifestyle modification programs are more successful than weight loss programs in that they promote healthy living, not just healthy eating. Lifestyle modification programs for weight loss generally include proper nutrition, proper exercise in terms of frequency, type, and duration; stress management, smoking cessation and even psychological assessment and/or treatment in order to create an environment of wellness both physically and environmentally. The overall goal of lifestyle modification programs is therefore lifestyle modification, not necessarily weight loss. However, while lifestyle modification and weight loss are different, they are not mutually exclusive. Weight loss programs are geared towards weight loss but should include lifestyle modification techniques so that the weight loss can be maintained. This is because losing weight as a product of dietary and exercise changes is often not the issue; making those changes a way of life is crucial to the maintenance of those changes. For example, if a person chooses to stop smoking but continues to spend time participating in the kinds of activities that were conducive to smoking for them, they are less likely to be able to continue with cessation. It is one thing to lose the weight and quite another tokeep it off over time. This paper will address the evaluation of the UNC Wellness Center program Weigh To Wellness. It is the goal of UNC Wellness Center to create a weight loss program that offers lifestyle modification techniques for weight loss that can be expanded beyond UNC Wellness Center and offered to UNC Hospital employees.

Consensus-ADMM for General Quadratically Constrained Quadratic Programming

Year: 2016

description: Non-convex quadratically constrained quadratic programming (QCQP) problems have numerous applications in signal processing, machine learning, and wireless communications, albeit the general QCQP is NP-hard, and several interesting special cases are NP-hard as well. This paper proposes a new algorithm for general QCQP. The problem is first reformulated in consensus optimization form, to which the alternating direction method of multipliers (ADMM) can be applied. The reformulation is done in such a way that each of the sub-problems is a QCQP with only one constraint (QCQP-1), which is efficiently solvable irrespective of (non-)convexity. The core components are carefully designed to make the overall algorithm more scalable, including efficient methods for solving QCQP-1, memory efficient implementation, parallel/distributed implementation, and smart initialization. The proposed algorithm is then tested in two applications: multicast beamforming and phase retrieval. The results indicate superior performance over prior state-of-the-art methods.

Association between Exercise Frequency and Healthcare Costs Within an Employee Population at Duke University
Creators: name: Caretto, David
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Background: Several analyses indicate that employee populations with a body mass index (BMI) > 25 are associated with higher healthcare expenditures, increased workers' compensation and disability claims, and greater levels of absenteeism compared with normal weight employees. Modifiable risk factors, such as obesity and physical inactivity, are proposed to account for the greatest proportion of these costs. Objective: To determine if increased exercise frequency is associated with decreased healthcare costs among an employee population. Methods: This study used an integrated database linking employee demographics, health risk appraisal (HRA) information, and health insurance claims. Negative binomial regression, with a generalized estimated equations (GEE) approach, was used to analyze the relationship between self-reported exercise frequency and cost, adjusting for important covariates such as age, sex, race/ethnicity, calendar time period and BMI category. In addition, this report is supplemented with a limited review of the literature assessing the effect of workplace wellness programs on healthcare costs (Appendix). Results: This cohort contained 16154 individuals and 32044 person-years of health claims experience over ten years of data. A statistically significant association was found between exercise frequency and reductions in total annual medical and pharmacy costs paid independent of BMI category (p<0.05). For medical costs, the reduction in healthcare costs demonstrated a nadir in expenditures for employees who exercise 4-5 days per week and a moderate rise among employees who exercise 6-7 days per week. This effect was not observed among pharmacy costs paid, where increased exercise frequency was associated with decreased expenditures. These reductions in healthcare costs were associated with several major diagnostic category (MDC) and prescription drug class subgroups. These results are consistent with findings from the limited review of the literature, which demonstrate decreased healthcare costs among employee populations that participate in workplace wellness programs. Conclusions: This cohort demonstrates a broad trend of decreased healthcare costs, including annual medical and pharmacy costs paid, in employee populations with increased exercise frequency. This association exhibits a statistically significant reduction in pharmacy costs and a clinically significant lowering of costs generated by MDC subgroups. In promoting higher levels of exercise frequency, employers may lower modifiable risk factors for chronic disease and reduce healthcare costs among their employee population.

Mitigating the Risk of Knowledge Leakage in Knowledge Intensive Organizations: a Mobile Device Perspective

description: In the current knowledge economy, knowledge represents the most strategically significant resource of organizations. Knowledge-intensive activities advance innovation and create and sustain economic rent and competitive advantage. In order to sustain competitive advantage, organizations must protect knowledge from leakage to third parties, particularly competitors. However, the number and scale of leakage incidents reported in news media as well as industry whitepapers suggests that modern organizations struggle with the protection of sensitive data and organizational knowledge. The increasing use of mobile devices and technologies by knowledge workers across the organizational perimeter has dramatically increased the attack surface of organizations, and the corresponding level of risk exposure. While much of the literature has focused on technology risks that lead to information leakage, human risks that lead to knowledge leakage are relatively understudied. Further, not much is known about strategies to mitigate the risk of knowledge leakage using mobile devices, especially considering the human aspect. Specifically, this research study identified three gaps in the current literature (1) lack of in-depth studies that provide specific strategies for knowledge-intensive organizations based on their varied risk levels. Most of the analysed studies provide high-level strategies that are presented in a generalised manner and fail to identify specific strategies for different organizations and risk levels. (2) lack of research into management of knowledge in the context of mobile devices. And (3) lack of research into the tacit dimension of knowledge as the majority of the literature focuses on formal and informal strategies to protect explicit (codified) knowledge.

description: The MAJORANA Collaboration is constructing the MAJORANA DEMONSTRATOR, an ultra-low background, 40-kg modular HPGe detector array to search for neutrinoless double beta decay in 76Ge. In view of the next generation of tonne-scale Ge-based 0nbb-decay searches that will probe the neutrino mass scale in the inverted-hierarchy region, a major goal of the MAJORANA DEMONSTRATOR is to demonstrate a path forward to achieving a background rate at or below 1 count/tonne/year in the 4 keV region of interest around the Q-value at 2039 keV. The background rejection techniques to be applied to the data include cuts based on data reduction, pulse shape analysis, event coincidences, and time correlations. The Point Contact design of the DEMONSTRATOR 0s germanium detectors allows for significant reduction of gamma background.

description: Software architecture has been an active research field for nearly four decades, in which previous studies make significant progress such as creating methods and techniques and building tools to support software architecture practice. Despite past efforts, we have little understanding of how practitioners perform software architecture related activities, and what challenges they face. Through interviews with 32 practitioners from 21 organizations across three continents, we identified challenges that practitioners face in software architecture practice during software development and maintenance. We reported on common software architecture activities at software requirements, design, construction and testing, and maintenance stages, as well as corresponding challenges. Our study uncovers that most of these challenges center around management, documentation, tooling and process, and collects recommendations to address these challenges.

description: Das differenzierte Schilddrüsenkarzinom präsentiert sich bei Patienten oft vor dem 60. Lebensjahr und hat in der Regel eine gute Prognose. Dies führt dazu, dass bei der Indikationsstellung der Radioiodtherapie auch langfristige Nebenwirkungen im Rahmen einer Risiko-Nutzen-Abwägung berücksichtigt werden müssen. Daher wurde in den vergangenen Jahrzehnten wiederholt das Auftreten von Sekundärmalignomen nach einer Radioiodtherapie in der Behandlung von differenzierten Schilddrüsenkarzinomen untersucht. Im Rahmen einer ersten Publikation aus dem Jahr 2020 konnte ich bei Veröffentlichungen der letzten 10 Jahre teils deutliche Defizite feststellen. Deswegen erarbeitete ich daraufhin in einer 2022 veröffentlichten Publikation einen umfassenden Überblick über vorliegende Studien, um dann mittels validierter Werkzeuge die Qualität der Evidenz zu bewerten. Im Zuge dieser Arbeit wurden 5 269 Artikel identifiziert, von denen 69 als relevant eingestuft und begutachtet wurden. Nach Anwenden von vorher definierten Ein- und Ausschlusskriterien konnten 10 Artikel in die Analyse eingeschlossen werden. Diese wurden zunächst einzeln auf das Risiko für systematische Fehler untersucht, um anschließend die Qualität der Evidenz über alle Studien hinweg zu beurteilen. Getrennt voneinander bewertet wurde die Qualität der Evidenz bezüglich Sekundärmalignomen und sekundären hämatologischen Malignomen nach Radioiodtherapie sowie im Hinblick auf eine Dosis-Wirkungs-Beziehung. Im Mittel fanden die eingeschlossenen Studien ein um 14 % bis 84 % erhöhtes Risiko für Sekundärmalignome nach Radioiodtherapie. Das Risiko für sekundäre hämatologische Malignome war im Mittel um 30 % bis 150 % erhöht. In zahlreichen Studien konnten jedoch systematische Fehler identifiziert werden. Die Qualität der Evidenz in Bezug auf Sekundärmalignome nach Radioiodtherapie und einer Dosis-Wirkungs-Beziehung wurde als very low und hinsichtlich sekundären hämatologischen Malignomen als low bewertet. Die vorliegende Evidenz bezüglich des Auftretens von Sekundärmalignomen und sekundären hämatologischen Malignomen nach Radioiodtherapie sollte also mit Blick auf die Indikationsstellung mit großer Vorsicht interpretiert werden.
Student't mixture models for stock indices. A comparative study

description: We perform a comparative study for multiple equity indices of different countries using different models to determine the best fit using the Kolmogorov-Smirnov statistic, the Anderson-Darling statistic, the Akaike information criterion and the Bayesian information criteria as goodness-of-fit measures. We fit models both to daily and to hourly log-returns. The main result is the excellent performance of a mixture of three Student's $t$ distributions with the numbers of degrees of freedom fixed a priori (3St). In addition, we find that the different components of the 3St mixture with small/moderate/high degree of freedom parameter describe the extreme/moderate/small log-returns of the studied equity indices.

description: This work considers reasons for and implications of discarding the assumption of transitivity, which (transitivity) is the fundamental postulate in the utility theory of Von Neumann and Morgenstern, the adiabatic accessibility principle of Caratheodory and most other theories related to preferences or competition. The examples of intransitivity are drawn from different fields, such as law, biology, game theory, economics and competitive evolutionary dynamic. This work is intended as a common platform that allows us to discuss intransitivity in the context of different disciplines. The basic concepts and terms that are needed for consistent treatment of intransitivity in various applications are presented and analysed in a unified manner. The analysis points out conditions that necessitate appearance of intransitivity, such as multiplicity of preference criteria and imperfect (i.e. approximate) discrimination of different cases. The present work observes that with increasing presence and strength of intransitivity, thermodynamics gradually fades away leaving space for more general kinetic considerations. Intransitivity in competitive systems is linked to complex phenomena that would be difficult or impossible to explain on the basis of transitive assumptions. Human preferences that seem irrational from the perspective of the conventional utility theory, become perfectly logical in the intransitive and relativistic framework suggested here. The example of competitive simulations for the risk/benefit dilemma demonstrates the significance of intransitivity in cyclic behaviour and abrupt changes in the system. The evolutionary intransitivity parameter, which is introduced in the Appendix, is a general measure of intransitivity, which is particularly useful in evolving competitive systems. Quantum preferences are also considered in the Appendix.

description: In this work we examine the use of metal-organic framework (MOF) systems as host materials for the investigation of glassy dynamics in confined geometry. We investigate the confinement of the molecular glass former glycerol in three MFU-type MOFs with different pore sizes and study the dynamics of the confined liquid via dielectric spectroscopy. In accord with previous reports on confined glass formers, we find different degrees of deviations from bulk behavior depending on pore size, demonstrating that MOFs are well-suited host systems for confinement investigations.

description: We study the distribution of strike size, which we measure as lost person days, for a long period in several countries of Europe and America. When we consider the full samples, the mixtures of two or three lognormals arise as very convenient models. When restricting to the upper tails, the Pareto power law becomes almost indistinguishable of the truncated lognormal.
