description: Context: The Mira variable LX Cyg showed a dramatic increase of its pulsation period in the recent decades and appears to undergo an important transition in its evolution. Aims: We aim at investigating the spectral type evolution of this star over the recent decades as well as during one pulsation cycle in more detail and discuss it in connection with the period evolution. Methods: We present optical, near- and mid-IR low-resolution as well as optical high-resolution spectra to determine the current spectral type. The optical spectrum of LX Cyg has been followed for more than one pulsation cycle. Recent spectra are compared to archival spectra to trace the spectral type evolution and a Spitzer mid-IR spectrum is analysed for the presence of molecular and dust features. Furthermore, the current period is derived from AAVSO data. Results: It is found that the spectral type of LX Cyg changed from S to C sometime between 1975 and 2008. Currently, the spectral type C is stable during a pulsation cycle. It is shown that spectral features typical of C-type stars are present in its spectrum from ~0.5 to 14 $μ{\rm{m}}$. An emission feature at 10.7 $μ{\rm{m}}$ is attributed to SiC grains. The period of LX Cyg has increased from ~460 d to ~580 d within only 20 years, and is stable now. Conclusions: We conclude that the change in spectral type and the increase in pulsation period happened simultaneously and are causally connected. Both a recent thermal pulse (TP) and a simple surface temperature decrease appear unlikely to explain the observations. We therefore suggest that the underlying mechanism is related to a recent third dredge-up mixing event that brought up carbon from the interior of the star, i.e. that a genuine abundance change happened. We propose that LX Cyg is a rare transition type object that is uniquely suited to study the transformation from O- to C-rich stars in detail.

description: We present a general methodology for electromagnetic homogenization and characterization of bianisotropic metasurfaces formed by regular or random arrangements of small arbitrary inclusions at the interface of two different isotropic media. These topologies can provide the most general electric and magnetic surface-bound dipolar responses to incident electromagnetic waves. The approach unites and generalizes the earlier theories developed independently by two research groups: the joint group of profs. Holloway and Kuester and the joint group of profs. Simovski and Tretyakov. We demonstrate the use of both formalisms in several example cases and discuss the differences between the two approaches. Furthermore, we generalize the known theories for the bianisotropic metasurfaces located at interfaces between two different media or on a substrate. The generalized framework allows characterization of both periodical or amorphous metasurfaces. The developed analytical theory can be used in the analysis and synthesis of metasurfaces for a wide variety of applications.

description: Given an exceptional compact simple Lie group $G$ we describe new left-invariant Einstein metrics which are not naturally reductive. In particular, we consider fibrations of $G$ over flag manifolds with a certain kind of isotropy representation and we construct the Einstein equation with respect to the induced left-invariant metrics. Then we apply a technique based on Gröbner bases and classify the real solutions of the associated algebraic systems. For the Lie group ${\rm G}_2$ we obtain the first known example of a left-invariant Einstein metric, which is not naturally reductive. Moreover, for the Lie groups ${\rm E}_7$ and ${\rm E}_8$, we conclude that there exist non-isometric non-naturally reductive Einstein metrics, which are ${\rm Ad}(K)$-invariant by different Lie subgroups $K$.

description: A randomized controlled trial was conducted to examine the effectiveness of Adherence-Coping-Education (ACE) Therapy. Twenty-four individuals were randomized to receive 14 sessions of either ACE therapy in addition to treatment as usual (TAU), or Supportive Therapy (ST) in addition to TAU. Participants were assessed on measures of medication attitudes, insight, symptoms, and social functioning. ACE therapy was well tolerated, with comparable attrition rates between the two interventions and high therapy attendance. ACE Therapy was associated with significant improvements in medication attitudes as well as psychotic symptoms, insight and functioning. A greater proportion of individuals in the ACE condition had clinically significant change on positive symptom scores than did those in the ST condition. These results lend initial support for the feasibility of ACE Therapy, and suggest that it may facilitate recovery from an initial psychotic episode. Findings are discussed within the context of the study’s limitations.

description: We study ten galaxy groups and clusters suggested in the literature to be "fossil system (FS)" based on \chandra\ observations. According to the $M_{500}-T$ and $L_{\rm X}-T$ relations, the gas properties of FSs are not physically distinct from ordinary galaxy groups or clusters. We also first study the $f_{\rm gas,~2500}-T$ relation and find that the FS exhibits same as ordinary systems. The gas densities of FSs within $0.1r_{200}$, are $\sim 10^{-3}$ cm$^{-3}$, which is the same order as galaxy clusters. The entropies within $0.1r_{200}$ ($S_{0.1r_{200}}$) of FSs are systematically lower than those in ordinary galaxy groups which is consistent with previous report, but we find their $S_{0.1r_{200}}-T$ relation is more similar to galaxy clusters. The derived mass profiles of FSs are consistent with the Navarro, Frenk, \& White model in $(0.1-1)r_{200}$, and the relation between scale radius $r_{\rm s}$ and characteristic mass density $ta_{\rm c}$ indicates the self-similarity of dark matter halos of FSs. The range of $r_{\rm s}$ and $ta_{\rm c}$ of FSs are also close to those of galaxy clusters. Therefore, FSs share more common characteristics with galaxy clusters. The special birth place of the FS makes it as a distinct galaxy system type.

description: The coronal magnetic field directly or indirectly affects a majority of the phenomena studied in space physics. It provides energy for coronal heating, controls the release of coronal mass ejections (CMEs), and drives heliospheric and magnetospheric activity, yet the coronal magnetic field itself has proven difficult to measure. This difficulty has prompted a decades-long effort to develop accurate, timely, models of the field - an effort that continues today. We have developed a method for improving global coronal magnetic field models by incorporating the type of morphological constraints which could be derived from coronal images. Here we report promising initial tests of this approach on two theoretical problems, and discuss opportunities for application.

description: An open problem in evolutionary game dynamics is to understand the effect of peer pressure on cooperation in a quantitative manner. Peer pressure can be modeled by punishment, which has been proved to be an effective mechanism to sustain cooperation among selfish individuals. We investigate a symmetric punishment strategy, in which an individual will punish each neighbor if their strategies are different, and vice versa. Because of the symmetry in imposing the punishment, one might expect intuitively the strategy to have little effect on cooperation. Utilizing the prisoner's dilemma game as a prototypical model of interactions at the individual level, we find, through simulation and theoretical analysis, that proper punishment, when even symmetrically imposed on individuals, can enhance cooperation. Besides, we find that the initial density of cooperators plays an important role in the evolution of cooperation driven by mutual punishment.

description: Rare-earth elements (REEs) have long been believed to play a crucial role in a wide variety of several modern technologies, but insignificant roles for biological processes. In recent days, a growing body of evidence shows a variety of enzymes with REEs-dependent activities. For example, the soil-dwelling bacterium Pseudomonas putida KT2440 employs the REEs-dependent alcohol dehydrogenase (ADH), PedH (PP_2679), in order to degrade plant-, fungal-, and bacteria-derived volatiles. Mechanistically, PedH resides in the periplasm of P. putida and exhibits activity on a similar set of substrates as its strictly calcium-dependent counterpart PedE (PP_2674). As members of quinoproteins family, both enzymes strictly rely on the redox cofactor pyrroloquinoline quinone (PQQ), which plays an essential role in direct electron transfer towards a c-type cytochrome in the electron transport chain for bacterial ATP synthesis during the periplasmic oxidation process. There is no clear evidence till now why PedH could be REEs-dependent in its ADH activity while its counterpart PedE utilizes calcium to perform the same function. In the first part of this work, I have tried to get in-depth insights into the structural and mechanistic characterization of PedE and PedH. Structure analysis clearly showed that an aspartate amino acid residue (D325PedH) plays a significant role in the optimization of PedH towards the REEs-dependence. The functional analysis of both ADHs revealed that both enzymes use a cognate c-type cytochrome (PedF) in their periplasmic oxidation process where the REEs-dependent PedH has more catalytical efficiency compared to the calcium-dependent PedE. On the other hand, understanding the structure and mechanistic background of PedH enables me in collaboration with 2 research groups to engineer PedH as a novel tool for biocatalysis in the second part of this work. In our publication, PedH has been established for a biosynthetic pathway of 2,5-furandicarboxylic acid (FDCA), one of the top 12 value-added renewable chemicals that provides a promising alternative to the petroleum-based terephthalic acid to produce polymers, to reach the goal of net-zero greenhouse gas emissions.

description: Formulas for the solutions of initial value problems for ordinary differential equations with singular $δ^{(n)}$-like driving terms are derived in the framework of an algebra of generalized functions (of Colombeau type) over a field of generalized scalars. Some of the solutions might have physical meaning - such as of the electrical current after lightning or under superconductivity - but do not have counterparts in the theory of Schwartz distributions. What is somewhat unusual (compared with other similar works) is the involvement of infinitely large constants, such as $δ(0)$, in some of the formulas for the solutions.

description: We present a characterization of the completeness of the field of real numbers in the form of a \emph{collection of several equivalent statements} borrowed from algebra, real analysis, general topology, and non-standard analysis. We also discuss the completeness of non-Archimedean fields and present several examples of such fields. As an application, we exploit the characterization of the reals to argue that the Leibniz-Euler infinitesimal calculus in the $17^\textrm{th}$-$18^\textrm{th}$ centuries was already a rigorous branch of mathematics -- at least much more rigorous than most contemporary mathematicians prefer to believe. By advocating our particular historical point of view, we hope to provoke a discussion on the importance of mathematical rigor in mathematics and science in general. This article is directed to all mathematicians and scientists who are interested in the foundations of mathematics and the history of infinitesimal calculus.

description: We developed an algorithm to find and characterize gravitationally lensed galaxies (arcs) to perform a comparison of the observed and simulated arc abundance. Observations are from the Cluster Lensing And Supernova survey with Hubble (CLASH). Simulated CLASH images are created using the MOKA package and also clusters selected from the high resolution, hydrodynamical simulations, MUSIC, over the same mass and redshift range as the CLASH sample. The algorithm' s arc elongation accuracy, completeness and false positive rate are determined and used to compute an estimate of the true arc abundance. We derive a lensing efficiency of $4 \pm 1$ arcs (with length $\ge 6"$ and length-to-width ratio $\ge 7$) per cluster for the X-ray selected CLASH sample, $4 \pm 1$ arcs per cluster for the MOKA simulated sample and $3 \pm 1$ arcs per cluster for the MUSIC simulated sample. The observed and simulated arc statistics are in full agreement. We measure the photometric redshifts of all detected arcs and find a median redshift $z_s = 1.9$ with 33% of the detected arcs having $z_s > 3$. We find that the arc abundance does not depend strongly on the source redshift distribution but is sensitive to the mass distribution of the dark matter halos (e.g. the $c-M$ relation). Our results show that consistency between the observed and simulated distributions of lensed arc sizes and axial ratios can be achieved by using cluster-lensing simulations that are carefully matched to the selection criteria used in the observations.

description: Fractional repetition (FR) codes are a family of repair-efficient storage codes that provide exact and uncoded node repair at the minimum bandwidth regenerating point. The advantageous repair properties are achieved by a tailor-made two-layer encoding scheme which concatenates an outer maximum-distance-separable (MDS) code and an inner repetition code. In this paper, we generalize the application of FR codes and propose heterogeneous fractional repetition (HFR) code, which is adaptable to the scenario where the repetition degrees of coded packets are different. We provide explicit code constructions by utilizing group divisible designs, which allow the design of HFR codes over a large range of parameters. The constructed codes achieve the system storage capacity under random access repair and have multiple repair alternatives for node failures. Further, we take advantage of the systematic feature of MDS codes and present a novel design framework of HFR codes, in which storage nodes can be wisely partitioned into clusters such that data reconstruction time can be reduced when contacting nodes in the same cluster.

ASSOCIATIONS BETWEEN MATERNAL BODY DISSATISFACTION AND INFANT FEEDING STYLE AMONG A COHORT OF LOW-INCOME, NON-HISPANIC BLACK MOTHER-INFANT DYADS
Creators: name: Boley, Kayla

description: The prevalence of childhood and adolescent obesity has increased in the last several decades, with no evidence of plateau or decrease. Infant feeding style has been found to be associated with an increased risk of overweight and obesity in childhood and adolescence. This study sought to determine if maternal body dissatisfaction was associated with infant feeding style among a cohort of non-Hispanic black mother-infant dyads. A cross-sectional preliminary study found significant associations with non-responsive feeding styles early in the postpartum period. The current study explored this association longitudinally from 3- to 18-months of infant age. Multilevel mixed effects models indicate that maternal body dissatisfaction is positively associated with restrictive-diet-quality, and negatively associated with responsive-satiety throughout the postpartum period. Early feeding interventions should be tailored toward mothers to educate on postpartum body changes, positive body image, and appropriate infant feeding practices. This association should be explored in a larger, heterogeneous sample.

description: The iconographic history of the myth of Prometheus is strongly connected with literary tradition. However, the ways of representing the myth seem to undergo a sudden interference phenomenon starting from the third quarter of the fifth century BC as compared to the previous figurative tradition, whose first attestations date to the end of the seventh century BC. From the examination of textual and vascular occurrences, it appears that Attic theatre once again plays a leading role.

В данной работе проведены исследования усиления электрических полей и ГКР света в периодически профилированных диэлектрических метаповерхностях с поверхностным слоем серебра нанометровой толщины. Построена аналитическая теория и компьютерная модель плазмонных возбуждений в открытом резонаторе, образованном металлической нанорешеткой с синусоидальным профилем. При резонансных условиях электромагнитное поле многократно усиленно, что позволяет повысить чувствительность ГКР спектроскопии. Модулированная плазмонная метаповерхность изготовлена методом голографической интерференционной литографии, которая позволяет массово производить такие структуры [2]. Мы полагаем, что использование таких метаповерхностей в ГКР-спектроскопии для определения био-патогенов позволит повысить чувствительность обнаружения до сверхмалых концентраций, на порядки меньших требуемого порога обнаружения в биологических средах. Исследовано ГКР света от рецептор-связывающего домена (RBD) SARS-CoV-2, размещенного на металлической пленке без использования каких-либо молекулярных маркеров.

The ferromagnetic transition temperature of the SrRu0.9Cr0.1O3 film (166 K) was higher than that of the SrRuO3 film (147 K). Resonant photoemission spectroscopy experimentally revealed that the Cr 3dt2g orbital is hybridized with the Ru 4dt2g orbital in the SrRu0.9Cr0.1O3 film, supporting the assumption that the enhancement of the ferromagnetic transition temperature through Cr substitution stems from the widening of energy bands due to the hybridization of Cr 3dt2g and Ru 4dt2g orbitals. Furthermore, we found that the Hall resistivity of the SrRu0.9Cr0.1O3 film at low temperature is not a linear function of magnetic field in the high-field region where the out-of-plane magnetization was saturated; this result suggests that the SrRu0.9Cr0.1O3 film undergoes a structural transition at low temperature accompanied with the modulation of the Fermi surface.

description: We study the properties of heavy quarks as probes of strongly coupled plasmas with and without chemical potential by means of the gauge/gravity (AdS/CFT) duality. We compute the screening distance of a heavy quark-antiquark pair, its free energy, and the running coupling in large classes of non-conformal models arising as deformations of pure AdS space. We further investigate the energy loss of a heavy quark moving on a circular orbit as an example of an accelerated motion. These observables exhibit universal features independent of the deformation, pointing to strong-coupling universality. Our results should be relevant for processes involving heavy quarks and their bound states in the quark-gluon plasma, including the case of finite net baryon density.

description: STEM has attracted great consideration. The purpose of research is: (1) study STEM education, (2) explore STEM education with the creative and experiential activity, (3) suggest applying STEM education by designing technical toys for the middle school student. This study used a qualitative approach to carry out teaching integration for STEM education. The study applied to teaching the technological field in Vietnamese middle schools. The design performed at the Faculty of Technology Education, Hanoi National University of Education, Vietnam in April 2015. This study used the integrated approach to design subjects for STEM education. Two procedures for integration undertook with analysis. A sample of producing technical toy was consistent with developing students competencies. Integrated approach to STEM education through designing technical toys is possible. Recently, there has been a booming interest in Integrated Science, Technology, Engineering and Mathematics (STEM) education, but the approaches to STEM still remains controversial in diverse educational contexts. This study addressed this issue by exploring STEM education with the use of creative and experiential activities in a Vietnamese educational context. It also proposed a practical model for integrating STEM into teaching technology in secondary schools by designing technical toys. The implementation of the practical model suggests the possibility in using the integrated approach to STEM education through designing technical toys for middle school students in Vietnam. By applying the subject knowledge domains to solve real world problems and settings, the students can experience the benefits of a concrete and active learning in a meaningful and practical context. The multidisciplinary and interdisciplinary integration approaches are consistent with the development of the students competencies.

description: This paper studies a multi-period demand response management problem in the smart grid where multiple utility companies compete among themselves. The user-utility interactions are modeled by a noncooperative game of a Stackelberg type where the interactions among the utility companies are captured through a Nash equilibrium. It is shown that this game has a unique Stackelberg equilibrium at which the utility companies set prices to maximize their revenues (within a Nash game) while the users respond accordingly to maximize their utilities subject to their budget constraints. Closed-form expressions are provided for the corresponding strategies of the users and the utility companies. It is shown that the multi- period scheme, compared with the single-period case, provides more incentives for the users to participate in the game. A necessary and sufficient condition on the minimum budget needed for a user to participate is provided.

WEARING HIGH-HEELED SHOES: THE DISCUSSION OF MODERN "FOOTBINDING" IN REPUBLICAN CHINA
Creators: name: Liang, Yue
Publisher: name: University of North Carolina at Chapel Hill Graduate School
Year: 2015
Subjects: History

description: This thesis focuses on the discussion of women wearing high-heeled shoes in the Republican period (1912-1949), particularly the analogy drawn by Chinese intellectuals between footbinding and the wearing of high-heeled shoes. From the late 1910s onward, Chinese women appreciated having high-heeled shoes as part of their everyday wardrobes, not just as imported commercial objects, but more importantly, as signs of modern feminine beauty and a new fashionable lifestyle. The popularity of high-heeled shoes between the 1920s and the 1940s, however, sparked great debate over their impact on women’s health. Some intellectuals compared the wearing of high-heeled shoes to footbinding, based upon the assumption that both inflicted harmful effects on women’s bodies, and social lives, which in turn led to the ‘failure’ of the nation. Dissenters in this debate, on the other hand, considered such comparisons unfounded and ridiculous. They believed that women’s feelings, demands, and daily practice of wearing high-heeled shoes deserved more attention from intellectuals. This thesis argues that these different voices reflect the anxiety that Chinese intellectuals shared in the face of the changing world around them during the Republican period.

description: Die Verknüpfung zwischen Gericht und antikem Drama entstand, weil das Publikum den gerichtlichen Agon (Redewettstreit) mit stark formalisierten Reden im Theater wiedererkennen konnte. Er war ein fester Bestandteil vieler Dramen, jedoch nur selten als Gerichtsverhandlung. Aischylos' Eumeniden gelten als das gattungsbegründende Stück für das moderne Rechtsdrama. Sie weichen vom klassischen tragischen Format ab, da der zentrale Konflikt durch eine Gerichtsverhandlung aufgelöst wird. Aischylos vergleicht zwei Arten von Gerechtigkeit miteinander: Die Blutrache der Erinnyen und die institutionelle Rechtsprechung des Areopags. Aristophanes' Komödie Die Wespen kritisiert die politische Einflussnahme auf die athenischen Gerichte, zeigt aber keine seriöse Verhandlung, sondern eine Parodie einer solchen. Im antiken griechischen Roman werden Gerichtsverhandlungen in einzelnen Episoden dazu verwendet, um einschneidende Veränderungen im Schicksal einer Figur auszulösen, z. B. eine Verbannung.
description: The link between court and ancient drama arose because the audience could recognise the judicial agon (oratory contest) with highly formalised speeches in the theatre. It was an integral part of many dramas, but rarely as a court trial. Aeschylus' Eumenides are considered the genre-founding play for modern legal drama. It departs from the classical tragic format in that the central conflict is resolved through a court trial. Aeschylus compares two types of justice: the blood vengeance of the Erinyes and the institutional jurisdiction of the Areopagus. Aristophanes' comedy The Wasps criticises the political influence on the Athenian courts and shows a parody of a trial, but not a serious one. In the ancient Greek novel, court hearings are used in individual episodes to trigger drastic changes in a character's fate, e.g. exile.

A Steadying Hand or a Strike in the Night: Proliferation, Preemption, and Intervention in the Nuclearization of Second-Tier States
Creators: name: Dittmeier, Christopher R.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: Nuclear proliferation has in part led to a vastly-different security environment from that which existed during the Cold War. While Schelling's theory of deterrence through mutually-assured destruction established a precarious stability for forty years among the great powers, its assumptions render it of limited utility for evaluating the effects of nuclear proliferation below this level. Using an elaboration on Powell's bargaining models of conflict, this paper shows that the introduction of nuclear weapons in second-tier states radically alters the future distribution of power. These states therefore face a commitment problem vis-vis conventionally-stronger neighbors, inviting preemptive attacks on soon-to-be nuclear powers. This paper analyzes the dynamics behind this problem, as well as offers a theory of great-power intervention that explains the empirical lack of preemption.
