Subjects: subject: High Energy Physics - Theory (hep-th)

description: Using holography, we study non-perturbative effects in M-theory on orientifolds from the analysis of the S^3 partition functions of dual field theories. We consider the S^3 partition functions of N=4 Yang-Mills theory with O(n) gauge symmetry coupled to one (anti)symmetric and N_f fundamental hypermultiplets from the Fermi gas approach. In addition to the worldsheet instanton and membrane instanton corrections to the grand potential, which are also present in the U(n) Yang-Mills case, we find that there exist "half instanton" corrections coming from the effect of orientifold plane.

description: We report the detection of steady radio emission from the known X-ray source X9 in the globular cluster 47 Tuc. With a double-peaked C IV emission line in its ultraviolet spectrum providing a clear signature of accretion, this source had been previously classified as a cataclysmic variable. In deep ATCA imaging from 2010 and 2013, we identified a steady radio source at both 5.5 and 9.0 GHz, with a radio spectral index (defined as $S_ν\proptoν^α$) of $α=-0.4\pm0.4$. Our measured flux density of $42\pm4$ microJy/beam at 5.5 GHz implies a radio luminosity ($νL_ν$) of 5.8e27 erg/s, significantly higher than any previous radio detection of an accreting white dwarf. Transitional millisecond pulsars, which have the highest radio-to-X-ray flux ratios among accreting neutron stars (still a factor of a few below accreting black holes at the same X-ray luminosity), show distinctly different patterns of X-ray and radio variability than X9. When combined with archival X-ray measurements, our radio detection places 47 Tuc X9 very close to the radio/X-ray correlation for accreting black holes, and we explore the possibility that this source is instead a quiescent stellar-mass black hole X-ray binary. The nature of the donor star is uncertain; although the luminosity of the optical counterpart is consistent with a low-mass main sequence donor star, the mass transfer rate required to produce the high quiescent X-ray luminosity of 1e33 erg/s suggests the system may instead be ultracompact, with an orbital period of order 25 minutes. This is the fourth quiescent black hole candidate discovered to date in a Galactic globular cluster, and the only one with a confirmed accretion signature from its optical/ultraviolet spectrum.

description: We study the spin transport in the low temperature regime (often referred to as the precession-dominated regime) between a ferromagnetic Fermi liquid (FFL) and a normal metal metallic Fermi liquid (NFL), also known as the F/N junction, which is considered as one of the most basic spintronic devices. In particular, we explore the propagation of spin waves and transport of magnetization through the interface of the F/N junction where nonequilibrium spin polarization is created on the normal metal side of the junction by electrical spin injection. We calculate the probable spin wave modes in the precession-dominated regime on both sides of the junction especially on the NFL side where the system is out of equilibrium. Proper boundary conditions at the interface are introduced to establish the transport of the spin properties through the F/N junction. A possible transmission conduction electron spin resonance (CESR) experiment is suggested on the F/N junction to see if the predicted spin wave modes could indeed propagate through the junction. Potential applications based on this novel spin transport feature of the F/N junction are proposed in the end.

description: Mittelalterliche Glasmalereifenster, aber auch die in den letzten Jahrzehnten in ihrer Bedeutung wieder entdeckten Glasmalereien des 19. und 20. Jahrhunderts sind von unschätzbarem Wert und gehören zu dem bedeutenden Teil des europäischen Kulturerbes, den es zu bewahren gilt. Im heutigen Polen waren häufig - geschichtsbedingt - bei der Errichtung von Bauten und der Schaffung ihrer künstlerischen Ausstattung deutsche Architekten und Künstler beteiligt. Die so entstandenen Meisterwerke zu erhalten, ist eine große Aufgabe, die bei den von Jahr zu Jahr bedenklich zunehmenden Umweltschäden nicht unterschätzt werden darf. Dies gilt nicht nur für die schlesischen Regionen, sondern ebenso für die angrenzenden Gebiete, wie z. B. in Kujawien mit bedeutenden, aber gleichzeitig durch Umweltschadstoffe stark gefährdeten Kunstdenkmälern. Dazu gehören auch frühe Glasmalereien aus dem 13. bis 14. Jahrhundert in der zum Weltkulturerbe gehörenden Johanniskirche zu Thorn (Torun) und im Dom zu Leslau (Wloclawek)

Year: 2008

description: In North Carolina, the annual teacher turnover rate for school districts averages more than 12%, with some districts as high as 24%. Research suggests that lowering class sizes improves educational indicators such as student achievement, student behavior, and teacher workload. This study used data from the 2006 North Carolina Governor's Working Condition Survey and from one Southeastern school district to investigate the relationship between class size and teacher turnover for the district's Kindergarten teachers during the school year 2005-2006. This study examined the effects of teachers' class size on job retention. It also compared the effects of student achievement, minority and poverty enrollment, and English Language Learners on teacher retention. No significant relationships were found for teacher class size and retention. However, as students achieve higher scores on state tests, teachers are more likely to stay in their current positions. Implications for future research and educational policy are discussed.

description: This is a pre-registration of a study examining why people explore negative news articles related to the COVID-19 crisis. Our sample was divided into an exploration dataset and a validation dataset. The exploration dataset was used to explore which motivational dimensions predicted choices to read personal stories and factual news about the COVID-19 crisis. The validation dataset will be used to test confirmatory, pre-registered hypotheses that follow from the exploratory analysis of the exploration dataset. This pre-registration documents the confirmatory hypotheses that we will test in the validation dataset, including our exact statistical approach.

description: Marina Apollonio (b. 1940) was part of the historical movement known as ‘programmed art’ in the 1960s and 1970s. Like other members of optic and kinetic art, she tends towards a depersonalised approach to art making in opposition with expressive abstraction. Her works are ‘calculated’ dynamic objects and spaces for the viewer’s experience.In 2021, the work Fusione Circolare was redesigned and combined with Endings, an electroacoustic music composition made from the sounds of worn grooves in vinyl records. Acoustic fragments are juxtaposed in a layered mosaic that creates a complex and oscillating musical text reminiscent of mid-twentieth century musique concrète but also rooted in the polyrhythmic architectures of techno music. The visual-kinetic part of the work is a double spiral of black and white lines. A straight-line radius crosses the image from center to perimeter, indicating the beginning and end of the cyclic period. When rotating at the right speed, the visual and musical texts are synchronised and share a common time and cyclical tactus. The result is a graphical/conceptual score of music and a visual concretisation of what is heard. It is impossible to separate the music from the work’s optical-kinetics: the moving shape seems to dictate – rather than describe – what is heard. The article presents an analysis of the practise-based research and artistic collaboration between Marina Apollonio and the author.

description: A radio-guided surgery technique exploiting $β^-$ emitters is under development. It aims at a higher target-to-background activity ratio implying both a smaller radiopharmaceutical activity and the possibility of extending the technique to cases with a large uptake of surrounding healthy organs. Such technique requires a dedicated intraoperative probe detecting $β^-$ radiation. A first prototype has been developed relying on the low density and high light yield of the diphenylbutadiene doped para-therphenyl organic scintillator. The scintillation light produced in a cylindrical crystal, 5 mm in diameter and 3 mm in height, is guided to a photo-multiplier tube by optical fibres. The custom readout electronics is designed to optimize its usage in terms of feedback to the surgeon, portability and remote monitoring of the signal. Tests show that with a radiotracer activity comparable to those administered for diagnostic purposes the developed probe can detect a 0.1 ml cancerous residual of meningioma in a few seconds.

description: We report early optical linear polarization observations of two gamma-ray bursts made with the MASTER robotic telescope network. We found the minimum polar- ization for GRB150301B to be 8% at the beginning of the initial stage, whereas we detected no polarization for GRB150413A either at the rising branch or after the burst reached the power-law afterglow stage. This is the earliest measurement of the polarization (in cosmological rest frame) of gamma-ray bursts. The primary intent of the paper is to discover optical emission and publish extremely rare (unique) high- quality light curves of the prompt optical emission of gamma-ray bursts during the non-monotonic stage of their evolution. We report that our team has discovered the optical counterpart of one of the bursts, GRB150413A.

description: An optically thin $p$-$^{11}$B plasma loses more energy to bremsstrahlung than it gains from fusion reactions, unless the ion temperature can be elevated above the electron temperature. In thermal plasmas, the temperature differences required are possible in small Coulomb logarithm regimes, characterized by high density and low temperature. The minimum Lawson criterion for thermal $p$-$^{11}$B plasmas and the minimum $ρR$ required for ICF volume ignition are calculated. Ignition could be reached more easily if the fusion reactivity can be improved with nonthermal ion distributions. To establish an upper bound for this utility, we consider a monoenergetic beam with particle energy selected to maximize the beam- thermal reactivity. Channeling fusion alpha energy to maintain such a beam facilitates ignition at lower densities and $ρR$, improves reactivity at constant pressure, and could be used to remove helium ash. The gains realized with a beam thus establish an upper bound for the reductions in ignition threshold that can be realized with any nonthermal distribution; these are evaluated for $p$-$^{11}$B and DT plasmas.

description: We give a complete and explicit description of the kinematical data of higher gauge theory on principal 2-bundles with the string 2-group model of Schommer-Pries as structure 2-group. We start with a self-contained review of the weak 2-category Bibun of Lie groupoids, bibundles and bibundle morphisms. We then construct categories internal to Bibun, which allow us to define principal 2-bundles with 2-groups internal to Bibun as structure 2-groups. Using these, we Lie-differentiate the 2-group model of the string group and we obtain the well-known string Lie 2-algebra. Generalizing the differentiation process, we find Maurer-Cartan forms leading us to higher non-abelian Deligne cohomology, encoding the kinematical data of higher gauge theory together with their (finite) gauge symmetries. We end by discussing an example of non-abelian self-dual strings in this setting.

Environmental Controls on the Growth of Dune-Building Grasses and the Effect of Plant Morphology on Coastal Foredune Formation

description: Vegetated coastal foredunes protect habitats and infrastructure from storm-driven flooding. To improve understanding of foredune formation and morphology by quantifying the relationship between plant growth and position (cross-shore and elevation), I planted and monitored 180 individuals (Ammophila breviligulata, Spartina patens, Uniola paniculata) on Hog Island, Virginia. Growth in all species was correlated with change in elevation, and varied with position in S. patens and U. paniculata. Relationships were most predictive in A. breviligulata and U. paniculata. Transplant basal area and lateral spreading was greater at low elevations (340 cm2, 48%) than at intermediate (95, 17%) or high elevations (107, 20%). I derived allometric scaling relationships relating longest visible leaf length to basal and frontal area and found that the empirical ratio of basal-to-frontal area (~0.8, all species) maximized dune height in a morphodynamic foredune growth model. Model results suggest that plant morphology exerts a nonlinear control on dune morphology.

description: We address the problem of optimally controlling connected and automated vehicles (CAVs) crossing an urban intersection without any explicit traffic signaling, so as to minimize energy consumption subject to a throughput maximization requirement. We show that the solution of the throughput maximization problem depends only on the hard safety constraints imposed on CAVs and its structure enables a decentralized optimal control problem formulation for energy minimization. We present a complete analytical solution of these decentralized problems and derive conditions under which feasible solutions satisfying all safety constraints always exist. The effectiveness of the proposed solution is illustrated through simulation which shows substantial dual benefits of the proposed decentralized framework by allowing CAVs to conserve momentum and fuel while also improving travel time.

La vida jaibera: the gendered work and migration experiences of female guestworkers in the rural southeast
Creators: name: Straut Eppsteiner, Holly K.
Publisher: name: University of North Carolina at Chapel Hill
Year: 2014

description: Recruitment of female guestworkers by the U.S. seafood processing industry provides Mexican women with opportunities to support their families financially through legal, seasonal labor migration--but at the cost of family separation. Interviews with workers from two plants in the rural Southeast and two formers workers demonstrate that the separation of production and reproduction means that women must negotiate migration within gendered models of marriage and motherhood across borders. Their accounts indicate that family contexts interact with precarious legal status to shape women's migration experiences, possibilities for permanent settlement, and U.S. labor market opportunities. Despite classification as temporary nonimmigrants, I find that crab pickers, or jaiberas, use seasonal migration to the United States as a long-term strategy to support families in Mexico, and are held in temporary positions in both locations. Political and labor market contexts and family arrangements subject them systems of control that have important policy implications.

description: We perform an updated analysis on the searches for the anomalous FCNC Yukawa interactions between the top quark, the Higgs boson, and either an up or charm quark ($\rm tqh,\ q=u,\ c$). We probe the observability of the FCNC top-Higgs couplings through the processes $\rm e^- p\rightarrow ν_e \bar{t} \rightarrow ν_e h \bar{q}$ (signal.I) and $\rm \ e^- p \to ν_e h b$ (singal.II) at the proposed electron proton (ep) colliders, where the Higgs boson decays to a $\rm b\bar{b}$ pair. We find that at the high luminosity (1 $\rm ab^{-1}$) ep colliders where the electrons have a polarisation of $\rm 80\%$ and electron energy is typical 60 GeV, the 2$σ$ upper limit on $\rm Br(t\to uh)$ are $0.15\times 10^{-2}$($2.9\times 10^{-4}$) at the 7TeV@LHeC(50TeV@FCC-eh) for signal.I and $0.15\times 10^{-2}$($2.2\times 10^{-4}$) for signal.II. We also give an estimate on how the sensitivity (take signal.I as examples) would change when we reduce the electron beam energy from 60 GeV to 50 GeV or even 40 GeV due to the cost reason. The conclusion is that the discovery potential reduce $8.7\%$($29.4\%$) if the electron beam change from 60GeV to 50(40) GeV at the 7TeV LHeC, and $16.8\%$($19.8\%$) at the 50 TeV FCC-eh.

description: We investigate one-dimensional (1D) Majorana bound states (MBSs) realized in terms of the helical edge states of a 2D quantum spin-Hall insulator (QSHI) in a heterostructure with a superconducting substrate and two ferromagnetic insulators (FIs). By means of Bogoliubov-de Gennes approach we demonstrate that there is a helical spin texture in the MBS wave function with a pitch proportional to the Fermi momentum of the helical edge states of QSHI. Moreover, simultaneous detection on local density of states by scanning tunneling microscopy and spectroscopy at a position close to one FI edge and at the midpoint between two FIs can not only map out the energy spectrum $\pm E \cos(ϕ/2)$, but also prove experimentally that the two quasiparticle excitations do not mix with each other as protected by the parity conservation associated with the MBSs.

description: The equilibrium structure and functional properties exhibited by brownmillerite oxides, a family of perovskite-derived structures with alternating layers of $B$O$_6$ octahedra and $B$O$_4$ tetrahedra, viz., ordered arrangements of oxygen vacancies, is dependent on a variety of competing crystal-chemistry factors. We use electronic structure calculations to disentangle the complex interactions in two ferrates, Sr$_2$Fe$_2$O$_5$ and Ca$_2$Fe$_2$O$_5$, relating the stability of the equilibrium (strain-free) and thin film structures to both previously identified and newly herein proposed descriptors. We show that cation size and intralayer separation of the tetrahedral chains provide key contributions to the preferred ground state. We show the bulk ground state structure is retained in the ferrates over a range of strain values; however, a change in the orientation of the tetrahedral chains, i.e., a perpendicular orientation of the vacancies relative to the substrate, is stabilized in the compressive region. The structure stability under strain is largely governed by maximizing the intraplane separation of the `dipoles' generated from rotations of the FeO$_4$ tetrahedra. Lastly, we find that the electronic band gap is strongly influenced by strain, manifesting as an unanticipated asymmetric-vacancy alignment dependent response. This atomistic understanding establishes a practical route for the design of novel functional electronic materials in thin film geometries.

description: The theory of two-dimensional linear quaternion-valued differential equations (QDEs) was recently established (see Kou and Xia, SAPM). Some profound differences between QDEs and ODEs were observed. Also, an algorithm to evaluate the fundamental matrix by employing the eigenvalues and eigenvectors was presented in [Kou and Xia, SAPM]. However, the fundamental matrix can be constructed providing that the eigenvalues are simple. If the linear system has multiple eigenvalues, how to construct the fundamental matrix? In particular, if the number of independent eigenvectors might be less than the dimension of the system. That is, the numbers of the eigenvectors is not enough to construct a fundamental matrix. How to find the "missing solutions"? The main purpose of this paper is to answer this question. Furthermore, Caley determinant for Quaternion-valued matrix was adopted to proceed the theory of QDEs in [Kou and Xia, SAPM]. One big disadvantage of Caley determinant is that it can be expanded along the different rows and columns. This may lead to different results due to non-commutativity of the quaternions. This approach is not convenient to be used. The novel definition of determinant for Quaternion-valued matrix based on permutation is introduced to analyze the theory. This newly definition of determinant has great advantage compare to Calay determinant.

OLONITE SAMPLING TECHNIQUE AND TARO YAMANE SAMPLING METHOD: THE PARADIGM SHIFT
Creators: name: OLONITE, Oluyemi Ayodele

Year: 2022
Subjects: Olonite, Sampling, Technique, Taro, Yamane, Population

description: The Olonite Sampling Technique is a sampling method that is used for small and large population. It was developed as a solution to the short comings of the Taro Yamane Sampling Technique. OST ranges
 from “1 – 1,280,000,000 (one - one billion two hundred and eighty million) population” and 1 - 59,500, having two (2) categories with five (5) versions each. OST asserts that for some set of levels of significance, a particular category and version of sampling formulae should be adopted; level of significance 0.15, 0.1, 0.05, 0.2, 0.01, 0.002 and 0.001 should focus on the category 1 and use the total population to know the version to be considered. For level of significance 0.4, 0.3, and 0.2, the category
 2 should be considered and the total population should be used to determine the version to be considered. The Olonite Sampling Technique supports the 2/3 rule to a logical extent. Taro Yamane Sampling Method can only be used for populations below “four hundred (400)” and using Taro Yamane for a population above 400 might not give us a result closer to reality as the half value will not be attained using the Taro Yamane Sampling Technique but the Olonite Sampling Technique.
description: It is only the Olonite Sampling Technique that support the 2/3 rule to a reasonable extent for the significance level 0.15, 0.05, 0.02, 0.01, 0.002 & 0.001. The higher the Multiplier, the higher the sample size, however, this claim is to a specific extent because when the multiplier reaches a certain level, the diminishing the sample size becomes. For the full sampling size selection for each observed confidence level and population, check the "Olonite Sampling Table".

description: In an attempt to constrain and understand the emission mechanism of gamma rays, we perform a cross-correlation analysis of 15 blazars using light curves in millimetre, optical and gamma rays. We use discrete correlation function and consider only correlations significant at 99 per cent level. A strong correlation was found between 37 and 95 GHz with a near-zero time delay in most of the sources, and ~1 month or longer in the rest. A similar result was obtained between the optical and gamma-ray bands. Of the 15 sources, less than 50 per cent showed a strong correlation between the millimetre and gamma-ray or millimetre and optical bands. The primary reason for the lack of statistically significant correlation is the absence of a major outburst in the millimetre bands of most of the sources during the 2.5 yr time period investigated in our study. This may indicate that only the long-term variations or large flares are correlated between these bands. The variability of the sources at every waveband was also inspected using fractional rms variability. The fractional rms variability displays an increase with frequency reaching its maximum in the gamma rays.

Are We There Yet? Conceptualizing a Lighter Destination for Dark Tourism
Creators: name: Wisler, Caroline Michele
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: This thesis explores the contemporary phenomenon of dark tourism, defined by Lennon and Foley as the visitation of sites associated with the themes of death, dying, and atrocity. I present an analysis of identified patterns in the use of photography and film, the manipulation of landscape, and general exhibit presentation at dark tourism sites that focuses on dark tourism concerned with the events of the Holocaust, with particular attention given to the United States Holocaust Memorial Museum, Auschwitz-Birkenau, and the Holocaust Museum of Southwest Florida. These patterns contribute to the overall effect of distorting the history and compartmentalizing both spatially and temporally the events presented at dark tourism sites. This effect creates an artificial distancing between the tourist and the events depicted by situating them in a past more distant than to which they actually belong, in turn fostering a perspective that the events central to dark tourism are irrelevant to contemporary society. This artificial distancing, in conjunction with prevalent attitudes toward the tourist community, impacts the potential and purpose of dark tourism sites. Drawing on Nietzsche and Todorov, I conclude that the incorporation of alternative approaches to the presentation and use of history, integrated with the educational methodology presented by Freire and Reardon, may assist in developing the positive potential of dark tourism sites as well as transforming the negative reputation with which dark tourism sites are currently associated.

description: This paper investigates the possibility of the motion control of a ball with a pendulum mechanism with non-holonomic constraints using gaits - the simplest motions such as acceleration and deceleration during the motion in a straight line, rotation through a given angle and their combination. Also, the controlled motion of the system along a straight line with a constant acceleration is considered. For this problem the algorithm for calculating the control torques is given and it is shown that the resulting reduced system has the first integral of motion.

description: Multi-wavelength monitoring of Sgr A* flaring activity confirms the presence of embedded structures within the disk on size scales commensurate with the innermost accretion region, matching size scales that are derived from observed light curves within a broad range of wavelengths. We explore here a few of the observational signatures for an orbiting spot in non-keplerian motion near the event horizon of Sgr A* and model light curves from plunging emitting material near the marginally stable orbit of Sgr A*. All special and general relativistic effects (relativistic beaming, redshifts and blue-shifts, lensing effect, photon time delays) for unpolarized synchrotron emission near a Schwarzschild and Kerr black hole are all taken into consideration.

description: Centuries of devastating, recurrent outbreaks made the plague the archetypical disease of late medieval and early modern societies. Yet explanations of where it came from changed significantly over time. This dissertation examines how portrayals of the plague’s origins and place in society evolved separately in England and France, from the fourteenth to the eighteenth centuries. It relies in particular on plague tracts, a long-lasting literary genre that offered standardized therapeutic and curative advice. Medical historians have studied these sources to trace the development of medical thinking and practice over time. This dissertation focuses instead on the tracts’ changing discourses about the nature of the plague that are unique to time and to place. The study elaborates a new analytical method to investigate the materiality and contents of these historical documents: it involves close reading and a codicological/bibliographical comparison of approximately 180 tracts in manuscript and printed form, set into their appropriate historical contexts. Tract producers influenced how the plague was understood locally. England’s centralised print industry fostered the idea that London was the de facto site and source of the disease; France’s diffused industry, by contrast, encouraged the discussion and tracking of outbreaks in multiple cities. Understanding of the plague’s origins also evolved: belief in malevolent celestial events gave way, in turn, to blaming unhealthy local landscapes, then the living conditions of the poor, and finally the Ottoman Empire. By the mid-seventeenth century, tract writers pointed to the Ottoman Empire as the historical and geographical source of the disease. Especially during the tumultuous sixteenth century, religious discord, dynastic factionalism, and incapable rulers also appeared in the tracts as causes and effects of the plague. Plague tracts are direct expressions and reflections of the short- and medium-term historical waves in which they appeared. It is possible to trace through them shifts in political, cultural, and intellectual worldviews. The spread of humanism in particular influenced how tract writers discussed the plague’s origins and influence in society. This study thus demonstrates that understanding disease is a cultural construct specific to time and place. Observing the unique aspects of plague tracts enhances our ability to understand the place of disease in past human societies.
