description: A new type of gaseous micropattern particle detector based on a closed-cell microcavity plasma panel sensor is reported. The first device was fabricated with 1 x 1 x 2 mm cells. It has shown very clean signals of 0.6 to 2.5 volt amplitude, fast rise time of approximately 2 ns and FWHM of about 2 ns with very uniform signal shapes across all pixels. From initial measurements with beta particles from a radioactive source, a maximum pixel efficiency of greater than 95% is calculated, for operation of the detector over a 100V wide span of high voltages (HV). Over this same HV range, the background rate per pixel was measured to be 3 to 4 orders of magnitude lower than the rate with the cell illuminated by the beta source. Pixel-to-pixel count rate uniformity is within 3% and stable within 3% for many days. The time resolution is 2.4 ns, and a very low cell-to-cell crosstalk has been measured between cells separated by 2 mm.

description: Our knowledge of the equation of state of the quark gluon plasma has been continuously growing due to the experimental results from heavy ion collisions, due to recent astrophysical measurements and also due to the advances in lattice QCD calculations. The new findings about this state may have consequences on the time evolution of the early Universe, which can estimated by solving the Friedmann equations. The solutions of these equations give the time evolution of the energy density and also of the temperature in the beginning of the Universe. In this work we compute the time evolution of the QGP in the early Universe, comparing several equations of state, some of them based on the MIT bag model (and on its variants) and some of them based on lattice QCD calculations. Among other things, we investigate the effects of a finite baryon chemical potential in the evolution of the early Universe.
Classification of Periodicity in Subtraction Game Sequences

Subjects: game theory, parallelism, high-performance computing, batch processing

description: Periodic nim sequences produced by subtraction games are interesting because they have distinct patterns. Calculating periodicity that was highly variant from the mean required a large cache size and was computationally costly. Unnecessary use of such resources was best avoided by batch processing the majority of the data with a smaller cache size. Utilizing this method to expand the data to include larger set element values may be critical to comprehensively classifying such relationships. After enlarging the data set, more work is needed to codify these characterizations. In the future, the creation of one or more dynamic visualization programs may be critical to the human digestion of these expansive five dimensional data sets.

description: The Next-to-Minimal Supersymmetric Standard Model (NMSSM) contains a singlet-like pseudoscalar Higgs boson in addition to the doublet-like pseudoscalar of the Minimal Supersymmetric Standard Model. This new pseudoscalar can have a very low mass without violating the LEP exclusion constraints and it can potentially provide a hallmark signature of non-minimal supersymmetry at the LHC. In this analysis we revisit the light pseudoscalar in the NMSSM with partial universality at some high unification scale. We delineate the regions of the model's parameter space that are consistent with the up-to-date theoretical and experimental constraints, from both Higgs boson searches and elsewhere (most notably $b$-physics), and examine to what extent they can be probed by the LHC. To this end we review the most important production channels of such a Higgs state and assess the scope of its observation at the forthcoming Run-2 of the LHC. We conclude that the $b\bar{b}$-associated production of the pseudoscalar, which has been emphasised in previous studies, does not carry much promise anymore, given the measured mass of the Higgs boson at the LHC. However, the decays of one of the heavier scalar Higgsbosons of the NMSSM can potentially lead to the discovery of its light pseudoscalar. Especially promising are the decays of one or both of the two lightest scalar states into a pseudoscalar pair and of the heaviest scalar into a pseudoscalar and a $Z$ boson. Since the latter channel has not been explored in detail in the literature so far, we provide details of some benchmark points which can be probed for establishing its signature.

description: A longstanding question in stellar evolution is which massive stars produce black holes (BHs) rather than neutron stars (NSs) upon death. It has been common practice to assume that a given zero-age main sequence (ZAMS) mass star (and perhaps a given metallicity) simply produces either an NS or a BH, but this fails to account for a myriad of other variables that may effect this outcome, such as spin, binarity, or even stochastic differences in the stellar structure near core collapse. We argue that instead a probabilistic description of NS versus BH formation may be better suited to account for the current uncertainties in understanding how massive stars die. We present an initial exploration of the probability that a star will make a BH as a function of its ZAMS mass, $P_{\rm BH}(M_{\rm ZAMS})$. Although we find that it is difficult to derive a unique $P_{\rm BH}(M_{\rm ZAMS})$ using current measurements of both the BH mass distribution and the degree of chemical enrichment by massive stars, we demonstrate how $P_{\rm BH}(M_{\rm ZAMS})$ changes with these various observational and theoretical uncertainties. We anticipate that future studies of Galactic BHs and theoretical studies of core collapse will refine $P_{\rm BH}(M_{\rm ZAMS})$ and argue that this framework is an important new step toward better understanding BH formation. A probabilistic description of BH formation will be useful as input for future population synthesis studies that are interested in the formation of X-ray binaries, the nature and event rate of gravitational wave sources, and answering questions about chemical enrichment.

description: We study in-plane magnetic tunnel junctions with additional perpendicular polarizer for subnanosecond-current-induced switching memories. The spin-transfer-torque switching dynamics was studied as a function of the cell aspect ratio both experimentally and by numerical simulations using the macrospin model. We show that the anisotropy field plays a significant role in the dynamics, along with the relative amplitude of the two spin-torque contributions. This was confirmed by micromagnetic simulations. Real-time measurements of the reversal were performed with samples of low and high aspect ratio. For low aspect ratios, a precessional motion of the magnetization was observed and the effect of temperature on the precession coherence was studied. For high aspect ratios, we observed magnetization reversals in less than 1 ns for high enough current densities, the final state being controlled by the current direction in the magnetic tunnel junction cell.

description: We provide a detailed insight into piezoelectric energy generation from arrays of polymer nanofibers. For sake of comparison, we firstly measure individual poly(vinylidenefluoride-co-trifluoroethylene) (P(VDF-TrFe)) fibers at well-defined levels of compressive stress. Under an applied load of 2 mN, single nanostructures generate a voltage of 0.45 mV. We show that under the same load conditions, fibers in dense arrays exhibit a voltage output higher by about two orders of magnitude. Numerical modelling studies demonstrate that the enhancement of the piezoelectric response is a general phenomenon associated to the electromechanical interaction among adjacent fibers, namely a cooperative effect depending on specific geometrical parameters. This establishes new design rules for next piezoelectric nano-generators and sensors.

description: We propose a new type of experimentally feasible quantum quench protocol in which a quantum system is prepared in a coherent, localized excited state of a Hamiltonian. During the evolution of this solitonic excitation, the microscopic interaction is suddenly changed. We study the dynamics of solitons after this interaction quench for a wide class of systems using a hydrodynamic approach. We find that the post-quench dynamics is universal at short times, i.e. it does not depend on the microscopic details of the physical system. Numerical support for these results is presented using generalized non-linear Schroedinger equation, relevant for the implementation of the proposed protocol with ultracold bosons, as well as for the integrable Calogero model in harmonic potential. Finally, it is shown that the effects of integrability breaking by a parabolic potential and by a power-law non-linearity do not change the universality of the short-time dynamics.

description: Group field theories represent a 2nd quantized reformulation of the loop quantum gravity state space and a completion of the spin foam formalism. States of the canonical theory, in the traditional continuum setting, have support on graphs of arbitrary valence. On the other hand, group field theories have usually been defined in a simplicial context, thus dealing with a restricted set of graphs. In this paper, we generalize the combinatorics of group field theories to cover all the loop quantum gravity state space. As an explicit example, we describe the GFT formulation of the KKL spin foam model, as well as a particular modified version. We show that the use of tensor model tools allows for the most effective construction. In order to clarify the mathematical basis of our construction and of the formalisms with which we deal, we also give an exhaustive description of the combinatorial structures entering spin foam models and group field theories, both at the level of the boundary states and of the quantum amplitudes.

title: Die Bedeutung von Selbstfürsorge für Menschen mit hohem Unterstützungsbedarf aufgrund von Lernschwierigkeiten und psychischen Beeinträchtigungen
Creators: name: Theissler, Judith
Year: 2021

description: Gesundheit und Wohlbefinden werden wesentlich von der individuellen Lebensführung beeinflusst. In der vorliegenden Arbeit konnte gezeigt werden, dass Menschen mit hohem Unterstützungsbedarf aufgrund von Lernschwierigkeiten und psychischen Beeinträchtigungen im Vergleich zur Allgemeinbevölkerung ein erhöhtes Krankheitsrisiko haben und häufig von gesundheitlichen Benachteiligungen betroffen sind. Diese äußern sich unter anderem darin, dass diese Menschen häufig eine mangelhafte Gesundheitskompetenz sowie riskantes Gesundheitsverhalten aufweisen und es für sie kaum adäquate Maßnahmen zur Gesundheitsförderung und -prävention gibt. Da durch Selbstfürsorge ein Beitrag zur eigenen physischen und psychischen Gesundheit geleistet werden kann, ist diese im Hinblick auf das Wohlbefinden und die gesundheitliche Lage dieser Personengruppe von entscheidender Relevanz. Die vorliegende Masterarbeit widmet sich daher folgender Forschungsfrage: ‚Welche Bedeutung hat Selbstfürsorge für Menschen mit hohem Unterstützungsbedarf aufgrund von Lernschwierigkeiten und psychischen Beeinträchtigungen?‘. Dieser Frage soll in einer theoretischen und empirischen Auseinandersetzung nachgegangen werden. Dabei soll ermittelt werden, welche Relevanz der eigene Beitrag zur Förderung des physischen und psychischen Wohlbefindens für diese Menschen hat. Zunächst erfolgt eine theoretische Betrachtung der unterschiedlichen Begriffe und Theorien, die im Hinblick auf die Förderung von Gesundheit und Wohlbefinden durch Selbstfürsorge relevant sind, sowie der gesundheitlichen Lage der Zielgruppe dieser Arbeit. Diese Auseinandersetzung bildet die Grundlage für die anschließende empirische Untersuchung. Um die Forschungsfrage zu beantworten, wurden in Anlehnung an das Vorgehen des Life History Research die Lebensgeschichten von vier betroffenen Personen in Leichter Sprache erarbeitet. Anschließend wurde mit jeder Interviewperson ein problemzentriertes Interview zur Bedeutung von Selbstfürsorge geführt. Die Auswertung der Interviewdaten erfolgte in Anlehnung an die Grounded Theory nach Kathy Charmaz. Im Zuge der Auswertung konnte gezeigt werden, dass alle vier Interviewpersonen über mehrere Selbstfürsorgestrategien verfügen, mithilfe derer sie selbst Einfluss auf ihr physisches und psychisches Wohlbefinden nehmen können. Darüber hinaus liefert diese Arbeit Hinweise darauf, dass das individuelle Selbstfürsorgeverhalten von den eigenen Beziehungs- und Selbstfürsorgeerfahrungen geprägt wird.

description: Keywords: Social science education, Sweden, curriculum, teacher practice, research practice Highlights: • Social science education is the core subject assigned responsibility for citizenship education and holds a strong position in Swedish schools (policy and teaching). • Two reforms of curricula and syllabi through years 1–9 and 10–12 are upcoming. • There is a growing community of researchers investigating the purpose, design and conditions of social science education. • Research is mainly small-scale and qualitative and there is a lack of large-scale and/or quantitative studies. Purpose: This report provides an overview of social science education in primary and secondary education in Sweden with the purpose of introducing the international research community to policy-related issues concerning citizenship education, educational institutions and the scholarly state of the art. The principal topics are: a context of Sweden and its educational setting, the current policy documents and upcoming reforms, the state of teaching and teacher education, and the state of the art of Swedish social science education theory and research. Findings: Social science education holds a strong position as the main agent of citizenship education in Swedish schools and is a mandatory subject in every school year. The current and upcoming syllabi both emphasise disciplinary knowledge as well as citizenship education. Sweden has a growing community of researchers, but this community is somewhat fragmented because researchers originate from different disciplines.

Year: 2022

description: Keywords: School Community Assembly (SCA), direct democracy, school democratic governance Highlights: • Only 5% of Greek secondary education students are satisfied with the modus operandi of student communities and councils. • 5% of Greek adolescents are not interested in politics. • The School Community Assembly (SCA) is a new decision-making and deliberative institution in which all high school students and all faculty members participate under conditions of equality. • SCA promotes student’s direct participation in democratic decision-making and democratic school governance. • SCA serves educational goals such as making students more considerate and public-spirited, more respectful of others and more responsible concerning their relation with the school community. Purpose: We discuss and preliminarily evaluate the SCA, a novel educational experiment that takes place in a Greek high school. Drawing on contemporary educational and political theory as well as the rich history of democratic ideas SCA has a twofold aim: to enable students to substantially participate in direct democratic decision-making procedures and to engage them along with their teachers in democratic school governance. Design/methodology/approach: SCA operates under conditions of democratic equality and mutual respect, since all students and teachers have one vote and the same speech rights, and its decisions are binding for the school community. The preliminary results that SCA has yielded so far, are based on the systematic observation of the SCA proceedings and a structured self-report questionnaire for students. Findings: SCA promotes democratic school governance, improves the school’s social climate, contributes to the development of certain democratic attitudes and skills, and helps students to become more responsible and public-spirited citizens.

Publisher: name: JSSE - Journal of Social Science Education
Year: 2022

description: Keywords: citizenship competence, language, compositional effects, primary education Highlights: • Is acquiring individual citizenship knowledge also associated with peer language environment? • Students in classes with lower language achievement attain higher civic knowledge scores • High language-achievement students do better if part of lower language achievement class • Students with lower achievement level do better when part of a better performing class • Also the variance in language skills in the class influences citizenship knowledge Purpose: The degree to which inequalities in citizenship outcomes of students develop, may depend on the composition of the classroom. We investigate to what degree language competences of the students’ class mates are associated with youth citizenship knowledge. Design/methodology/approach: A Dutch nationally representative data was used. Given the nested structure of the data, multilevel analyses were performed. Findings: Inequalities in citizenship knowledge may be reduced when low language ability students are surrounded with classroom peers who display both variation in and high average levels of language ability. Being surrounded with high language ability peers was shown to have a negative general effect on citizenship knowledge of lower performing students, in line with the big-fish-little-pond effect. Research limitations/implications: Before recommending our findings as a basis for policy-making within schools, additional evidence must be gathered to establish the causal nature of the relationships suggested by our analyses.

description: Scholarly Communication today exists in a state we might best describe as ‘revolutionary stasis’. On the one hand, it is hard not to be impressed by the disruptive potential networked computing brings to the way researchers disseminate their results. The development of the Web twenty-six years ago ushered in a period in which scholars could organise, collaborate, and publish in fundamentally different ways than any time previously. There are new economic models for scholarly publishing, new models for career evaluation and progress, and new understandings of the relationship between scholars and the general public. At the same time, however, given this revolutionary potential, it is also hard not to be impressed equally by the difficulty these new ideas have had in actually disrupting pre-web ways of working. Indeed, in many cases, traditional markers of success and prestige have become if anything even more tenacious and entrenched than they were before Tim Berners-Lee first rolled out the Word Wide Web in early 1991. While there has been a slow-but-steady rise in the number of Open Access journals, academic publishing is still dominated by the same few presses (e.g., in the Humanities, Oxford, Cambridge, Blackwells, Routledge). Groups like the Modern Language Association (MLA) have worked to develop new forms of evaluation to accommodate new digital and collaborative forms of scholarship, even as measures of impact that focus on secondary and more traditional markers of use or prestige—such as the citation count or journal impact—have become increasingly important through national evaluation schemes such as the United Kingdom’s Research Excellence Framework or the Excellence in Research for Australia. In this paper, I argue that this frustrating state of affairs stems from a misunderstanding of how technological change works in Scholarly Communication. Although it is very tempting to assume that new platforms, methods of working, or economic models will replace their traditional counterparts, the experience of the last thirty years has demonstrated that new developments in this space tend to be complementary rather than competitive—that is to say that they introduce additional channels of communication or ways of working rather than replace existing ones. In this sense, our frustration with the degree to which technology has not changed scholarly communication may be because we are looking for the change in the wrong places: it is by supplementing and building on what came before, rather than, for the most part, replacing previous methods in fundamental ways, that such innovations ultimately change the way we work.
Using TV to teach?
Creators: name: Toll, Benjamin T
Publisher: name: JSSE - Journal of Social Science Education
Year: 2022

description: Keywords: classroom engagement, political interest, political knowledge, television drama Highlights: • Combining television shows allows us to increase student interest and knowledge of politics • Use of only one show can increase either interest or knowledge, but not both. Purpose: The typical Introduction to American Politics course has a plurality (if not majority) of students who take the course to satisfy a general education requirement rather than having a deep interest in the subject. It is also difficult because students lack interest and knowledge about the topic. Yet, many believe they know everything they need to in order to have opinions on the topic. This paper seeks a way to increase political interest and knowledge among students who are taking an introductory course. Design/methodology/approach: Using two well-known television programs, The West Wing and House of Cards, the study tests whether students gain an interest in politics and learn more about the topic when a class incorporates clips from popular shows. The study consists of 4 semesters with different treatments to determine the effects of each show and when the shows are combined on student interest, knowledge, and perceived political engagement. Findings: Students report being more interested in politics in a course that uses The West Wing because of its positive views toward American democracy. Yet, they are not necessarily more knowledgeable or feel that participation is important for doing well in courses. On the other hand, students in the House of Cards condition felt more knowledgeable about politics but were actually less interested in politics. Research limitations/implications: This study was completed in a small, rural, and largely conservative liberal arts college in the United States. While the students accurately reflected the student body at the institution, they were not representative of college students overall.

description: Few studies have investigated whether the utility of social support for patients with a relapsing, remitting illness varies by activity level of the disease.

description: Keywords: Citizenship education; Measuring citizenship competences; Output-driven approach; Data-use in education; Social outcomes of education Highlights: • Research on effective characteristics of citizenship education is still scarce. • An output-driven approach may improve the effectiveness of citizenship education. • We reflect on the feasibility of an output-driven approach to citizenship education. • We conclude that such an approach seems feasible for citizenship education. • Normativity and the availability and quality of measurement instruments need attention. Purpose: Scholars are increasingly paying attention to the characteristics of effective citizenship education. The systematic use of data to maximise student learning, also called an output-driven approach, is often presented as a powerful predictor of student outcomes. However, its effectiveness has not been studied in citizenship education. Therefore, this paper aims to theoretically reflect on whether an output-driven approach is also feasible for citizenship education. Methodology: We distinguish five building blocks of an output-driven approach and elaborate on their applicability in citizenship education. While doing so, we draw attention to the normative notion in citizenship education and the quality and availability of measurement instruments for citizenship competences. Both may challenge the application of an output-driven approach, particularly given the relatively young tradition of measuring citizenship competences. Findings: We conclude that an output-driven approach in citizenship education seems feasible, provided that the characteristics of citizenship education are carefully considered.

description: Housing is an issue that affects all individuals in society. People have firsthand experiences with housing daily. Housing is also a macro issue that is affected by and has implications for the nation’s economy and public policy. Despite the centrality of housing for individuals and society, few scholars have examined media coverage of housing issues and housing policy. This gap is especially problematic when considering the critical role of the housing market collapse in the 2008 Great Recession, the landmark housing policies instituted during the start of the Covid-19 pandemic, and the media's potential to shape perceptions of housing policy and the economy. In this study, I use content analysis to examine the media agenda-setting and framing of housing and housing policies from 2005 to 2010 and 2020 in the New York Times. I investigate whether housing is framed in episodic or thematic ways and how housing media frames changed in response to the economic collapse and the pandemic. I also examine the context of media agenda-setting using housing topics. Lastly, I pay particular attention to whether housing media frames and housing topics are racialized. The data for this project was collected from the New York Times between 2005 - 2010 and 2020. The search terms used to identify relevant news articles were housing policy, subprime, affordable housing, foreclosure, homeownership, and eviction. The articles identified are all from the front page of the New York Times.

description: Im Fokus dieser Dissertation steht der Prozess der subjektiven Bewertung der Beziehungsqualität. Im Zuge dieses Prozesses nutzen Personen ihr beziehungsrelevantes Wissen, um zu einem Urteil über die Qualität ihrer romantischen Paarbeziehung zu kommen.
 Entsprechend einer zweidimensionalen Konzeptualisierung der Beziehungsqualität wurde angenommen, dass der in der Vergangenheit präsentierte Prototyp der guten Paarbeziehung als Repräsentant der positiven Beziehungsqualität durch einen Prototyp der schlechten Paarbeziehung als Repräsentant der negativen Beziehungsqualität ergänzt werden muss, um die Bewertungsprozesse in romantischen Beziehungen ganzheitlich betrachten zu können.
 Mittels einer klassischen Prototypenanalyse wurde der Prototyp der schlechten Paarbeziehung etabliert (Studie 1, N = 130; Studie 2, N = 389).
 Aufbauend auf einem in dieser Arbeit erstmals postulierten kognitiv-motivationalen Modell der Beziehungsbewertung sollte die Rolle der Prototypen der guten und schlechten Paarbeziehung als kognitive Referenzpunkte für die Bewertung der Beziehungsqualität herausgestellt werden.
 In diesem Zusammenhang wurde angenommen, dass die Prototypen in Abhängigkeit der Verfolgung einer romantischen Annäherungs- oder Vermeidungsmotivation als Referenzpunkte im Bewertungsprozess eine unterschiedliche Bedeutung erhalten. Die Annahmen des Modells wurden in drei empirischen Studien geprüft.
 Es konnte gezeigt werden, dass die Prototypen der guten und schlechten Paarbeziehung einen Einfluss auf die Informationsverarbeitung haben, der in Abhängigkeit der romantischen Annäherungs- und Vermeidungsmotivation unterschiedlich ausgestaltet war (Studie 3, N = 202).
 Zudem beeinflussten die Orientierungen an den Prototypen auf einer impliziten (Studie 4, N = 268) und expliziten Ebene (Studie 5, N = 278) die Bewertung der Beziehungsqualität der eigenen Paarbeziehung.
 Jedoch ergaben sich uneinheitliche Ergebnisse bezüglich des Einflusses der Annäherungs- und Vermeidungsmotivation auf die Orientierungen an den Prototypen. Die kritische Reflexion der Ergebnisse der vorliegenden Arbeit führt zu möglichen Ansätzen für die weiterführende Forschung zum kognitiv-motivationalen Modell der Beziehungsbewertung.

description: The polarization of the light scattered by an optically dense, random solution of dielectric nanoparticles shows peculiar properties when the scatterers exhibit strong electric and magnetic polarizabilities. While the distribution of the scattering intensity in these systems shows the typical irregular speckle patterns, the helicity of the incident light can be fully conserved when the electric and magnetic polarizabilities of the scatterers are equal. We show that the multiple scattering of helical beams by a random dispersion of "dual" dipolar nano-spheres leads to a speckle pattern exhibiting a perfect isotropic constant polarization, a situation that could be useful in coherent control of light as well as in lasing in random media.

description: The use of Machine Learning has grown in popularity in various disciplines. Despite the popularity, the apparent ‘black box’ nature of such tools continues to be an area of concern. In this article, we attempt to unravel the complexity of this black box by exploring the use of artificial neural networks (ANNs), coupled with graph theory, to model and interpret the spatial distribution of building damage from extreme wind events at a community level. Structural wind damage is a topic that is mostly well understood for how wind pressure translates to extreme loading on a structure, how debris can affect that loading and how specific social characteristics contribute to the overall population vulnerability. While these themes are widely accepted, they have proven difficult to model in a cohesive manner, which has led primarily to physical damage models considering wind loading only as it relates to structural capacity. We take advantage of this modelling difficulty to reflect on two different ANN Models for predicting the spatial distribution of structural damage due to wind loading. Through graph theory analysis, we study the internal patterns of the apparent black box of Artificial Intelligence of the models and show that social parameters are key to predict structural damage.
Quantitative study of the AMS-02 electron/positron spectra: implications for the pulsar and dark matter properties

description: The AMS-02 has just published the unprecedentedly precise measurement of the cosmic electron and positron spectra. In this paper we try to give a quantitative study on the AMS-02 results by a global fitting to the electron and positron spectra, together with the updated positron fraction data. The Markov Chain Monte Carlo algorithm is adopted to do the fitting. The primary electron spectrum and the parameters for pulsars or dark matter which contribute extra positrons are determined simultaneously. We find that there is a hardening of the primary electron spectrum at $\sim 60$ GeV. With such a new feature at the background spectrum both the pulsars and dark matter can explain the AMS-02 results very well. The dark matter scenario shows a drop at positron fraction at $\sim 300$ GeV, however, suffers very strong constraints from Fermi $γ$-ray observations. The fitting results also suggest that the propagation model with convection may be more favored by the lepton data than the reacceleration model.

description: The Disease Activity Score based on 28 joints (DAS28) has been increasingly used in clinical practice and research studies of rheumatoid arthritis (RA). Studies have reported discordance between DAS28 based on erythrocyte sedimentation rate (ESR) versus C-reactive protein (CRP) in RA patients. However such comparison is lacking in African-Americans with RA.

description: In this work, we numerically demonstrate an infrared frequency-tunable selective thermal emitter made of graphene covered SiC deep gratings. Full-wave simulation shows temporally-coherent emission peak associated with magnetic polariton, whose resonance frequency can be dynamically tuned within the phonon absorption band of SiC by varying graphene chemical potential. An analytical inductor-capacitor circuit model is introduced to quantitatively predict the resonance frequency and further elucidate the mechanism for the tunable emission peak. Moreover, by depositing multiple layers of graphene sheets onto the SiC deep gratings, a large tunability of 8.5% in peak frequency can be obtained to yield the coherent emission covering a broad frequency range from 820 1/cm to 890 1/cm. The novel tunable met-amaterial could pave the way to a new class of tunable thermal sources in the infrared region.

description: Unusual transport properties deviating from the Fermi liquid are observed in ruthenates near a magnetic quantum-critical point (QCP). To understand the electronic properties of the ruthenates near and away from an antiferromagnetic (AF) QCP, I study the electronic structure and magnetic and transport properties for the $t_{2g}$-orbital Hubbard model on a square lattice in fluctuation-exchange approximation including Maki-Thompson (MT) current vertex correction (CVC). The results away from the AF QCP reproduce several experimental results of Sr$_{2}$RuO$_{4}$ qualitatively and provide new mechanisms about the enhancement of spin fluctuation at $Q_{\textrm{IC-AF}}\approx (0.66π,0.66π)$, larger mass enhancement of the $d_{xy}$ orbital than that of the $d_{xz/yz}$ orbital, and nonmonotonic temperature dependence of the Hall coefficient. Also, the results near the AF QCP explain the $T$-linear inplane resistivity in Sr$_{2}$Ru$_{0.075}$Ti$_{0.025}$O$_{4}$ and give an experimental test on the obtained temperature dependence of the Hall coefficient. I reveal spatial correlation including the self-energy of electrons beyond mean-field approximations is essential to determine the electronic properties of the ruthenates. I also show several ubiquitous transport properties near an AF QCP and characteristic transport properties of a multiorbital system by comparison with results of a single-orbital system near an AF QCP.
