description: We present 3D general relativistic magnetohydrodynamic(GRMHD) simulations of zero angular momentum accretion around a rapidly rotating black hole, modified by the presence of initially uniform magnetic fields. We consider serveral angles between the magnetic field direction and the black hole spin. In the resulting flows, the midplane dynamics are governed by magnetic reconnection-driven turbulence in a magnetically arrested (or a nearly arrested) state. Electromagnetic jets with outflow efficiencies ~10-200% occupy the polar regions, reaching several hundred gravitational radii before they dissipate due to the kink instability. The jet directions fluctuate in time and can be tilted by as much as ~30 degrees with respect to black hole spin, but this tilt does not depend strongly on the tilt of the initial magnetic field. A jet forms even when there is no initial net vertical magnetic flux since turbulent, horizon-scale fluctuations can generate a net vertical field locally. Peak jet power is obtained for an initial magnetic field tilted by 40-80 degrees with respect to the black hole spin because this maximizes the amount of magnetic flux that can reach the black hole. These simulations may be a reasonable model for low luminosity black hole accretion flows such as Sgr A* or M87.

description: The search for the first stars formed from metal-free gas in the universe is one of the key issues in astronomy because it relates to many fields, such as the formation of stars and galaxies, the evolution of the universe, and the origin of elements. It is not still clear if metal-free first stars can be found in the present universe. These first stars are thought to exist among extremely metal-poor stars in the halo of our Galaxy. Here we propose a new scenario for the formation of low-mass first stars that have survived until today and observational counterparts in our Galaxy. The first stars in binary systems, consisting of massive- and low-mass stars, are examined using stellar evolution models, simulations of supernova ejecta colliding with low-mass companions, and comparisons with observed data. These first star survivors will be observed as metal-rich halo stars in our Galaxy. We may have identified a candidate star in the observational database where elemental abundances and kinematic data are available. Our models also account for the existence of several solar-metallicity stars in the literature having space velocities equivalent to the halo population. The proposed scenario demands a new channel of star formation in the early universe and is a supplementary scenario for the origin of the known metal-poor stars.

description: Fuel subsidies, which artificially lower consumer prices through government spending, are frequently targeted for removal by economists and international organizations. What accounts for the variable outcomes of attempts to cut fuel subsidies in Latin America? Previous research attributes reform failure to the government’s poor strategic choices. While the government’s decisions are important, they depend on a functioning bureaucratic state apparatus for implementation. This article widens the lens of inquiry, theorizing that the presence of a Weberian bureaucracy creates the institutional preconditions that allow leaders latitude in designing and implementing politically optimal reform strategies, while a politicized and unprofessional bureaucracy limits leaders’ choices, driving politically volatile reforms. Through a pair of case studies, this article demonstrates that, in Brazil and Bolivia, state strength was causally prior to strategic choices in the reform process. In Brazil, the historically strong state was necessary in facilitating a gradual and multi-step reform process that ended in success, while in Bolivia, the deeply politicized state forced the government into adopting a “big-bang” approach that quickly failed after protests. My study shows that leaders in weak states have a narrower array of reform strategy choices available than their strong state counterparts. This finding propounds that the state is a crucial first mover in policy reform, casting doubt on the prospects of reforms that do not first address the deeper problem of state weakness.

description: We present K-band imaging of two ~30'x30' fields covered by the MUSYC Wide NIR Survey. The 1030 and 1255 fields were imaged with ISPI on the 4m Blanco telescope at CTIO to a 5 sigma point-source limiting depth of K~20 (Vega). Combining this data with the MUSYC Optical UBVRIz imaging, we created multi-band K-selected source catalogs for both fields. These catalogs, together with the MUSYC K-band catalog of the ECDF-S field, were used to select K<20 BzK galaxies over an area of 0.71 deg^2. This is the largest area ever surveyed for BzK galaxies. We present number counts, redshift distributions and stellar masses for our sample of 3261 BzK galaxies (2502 star-forming (sBzK) and 759 passively evolving (pBzK)), as well as reddening and star formation rate estimates for the star-forming BzK systems. We also present 2-point angular correlation functions and spatial correlation lengths for both sBzK and pBzK galaxies and show that previous estimates of the correlation function of these galaxies were affected by cosmic variance due to the small areas surveyed. We have measured correlation lengths r_0 of 8.89+/-2.03 Mpc and 10.82+/-1.72 Mpc for sBzK and pBzK galaxies respectively. This is the first reported measurement of the spatial correlation function of passive BzK galaxies. In the LambdaCDM scenario of galaxy formation, these correlation lengths at z~2 translate into minimum masses of ~4x10^{12} M_sun and ~9x10^{12} M_sun for the dark matter (DM) halos hosting sBzK and pBzK galaxies respectively. The clustering properties of the galaxies in our sample are consistent with them being the descendants of bright LBG at z~3, and the progenitors of present-day >1L* galaxies.

description: Im Kerameikos befindet sich am Südrand der Heiligen Straße, unmittelbar vor dem Heiligen Tor, ein klassischer Altar aus dem 5. Jahrhundert v. Chr. (heute unter einem Schutzdach aufgestellt). Bereits Ende des 19. Jahrhunderts wurde der marmorne Altar an anderer Stelle und auf wesentlich höherem Niveau, nämlich auf der Ecke des Proteichisma-Turms, aufgefunden. Bei Ausgrabungen 2002 konnte der ursprüngliche Platz des marmornen Altares innerhalb des Proteichisma-Turmes identifiziert werden. Er war in einem kleinen Temenos auf einer zweistufigen Kalksteinbasis aufgestellt. Die Basis wurde dann von dem Turm überbaut. Das warf die Frage auf, wo sich der Altar befunden hat, solange das Proteichisma (und damit sein Turm vor dem Heiligen Tor) verteidigungstechnisch für Athen relevant waren. Im Verlauf der Dokumentationskampagne 2022 konnte diese Frage teilweise geklärt werden.

description: The conventional framework for defining and understanding phases of matter requires thermodynamic equilibrium. Extensions to non-equilibrium systems have led to surprising insights into the nature of many-body thermalization and the discovery of novel phases of matter, often catalyzed by driving the system periodically. The inherent heating from such Floquet drives can be tempered by including strong disorder in the system, but this can also mask the generality of non-equilibrium phases. In this work, we utilize a trapped-ion quantum simulator to observe signatures of a non-equilibrium driven phase without disorder: the prethermal discrete time crystal (PDTC). Here, many-body heating is suppressed not by disorder-induced many-body localization, but instead via high-frequency driving, leading to an expansive time window where non-equilibrium phases can emerge. We observe a number of key features that distinguish the PDTC from its many-body-localized disordered counterpart, such as the drive-frequency control of its lifetime and the dependence of time-crystalline order on the energy density of the initial state. Floquet prethermalization is thus presented as a general strategy for creating, stabilizing and studying intrinsically out-of-equilibrium phases of matter.

Drama and its role in the integration of mentally challenged students : a case study
Creators: name: Powell, Jane E
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this study was to build up a picture of what was happening to two mildly mentally challenged students in an integrated Grade 9 Drama class. A case-study design was employed and the students were observed over one semester. References were also made to related events in the second semester. After analysing the files of the subjects, the teacher-researcher kept journals to track her thinking, planning, and responses to the events of the classroom. A videotape of two classes was made and a checklist was used to obtain feedback from an observer. A District Counsellor interviewed the subjects at the end of the first semester. The regular students in the subject class also wrote about the integration process and its effect on them. Because the study was descriptive, the objective was not to make conclusive statements that would apply to other classrooms. However, the issues that emerged concerned teacher and regular student readiness for the integration of the mentally challenged, the need to respond to the mentally challenged as individuals, the necessity for flexibility in programming, and the possibilities that mainstreaming offers for the growth of all those involved in the process.

description: The dispersion relation of surface plasmon polaritons in graphene that includes optical losses is often obtained for complex wave vectors while the frequencies are assumed to be real. This approach, however, is not suitable for describing the temporal dynamics of optical excitations and the spectral properties of graphene. Here, we propose an alternative approach that calculates the dispersion relation in the complex frequency and real wave vector space. This approach provides a clearer insight into the optical properties of a graphene layer and allows us to find the surface plasmon modes of a graphene sheet in the full frequency range, thus removing the earlier reported limitation (1.667 < $\hbarω/μ$ < 2) for the transverse-electric mode. We further develop a simple analytic approximation which accurately describes the dispersion of the surface plasmon polariton modes in graphene. Using this approximation, we show that transverse-electric surface plasmon polaritons propagate along the graphene sheet without losses even at finite temperature.

description: Необходимость прецедентного регулирования общественных отношений основывается и на многообразии общественной жизни и свободе человеческой инициативы. Свободное человеческое поведение влечет за собой настолько быстрое изменение общественных систем и структур, что адекватное законодательное регулирование этих изменений чаще всего невозможно. Авторы в статье делают вывод о том, что в российской правовой системе, как и в любой континентальной системе права, в той или иной форме прецедент как источник права существовал всегда. Более того, опосредованно он неизменно таковым и признавался, но при этом в научных работах метафора «источник права» к результатам судебной деятельности не применилась. Так, применение закона или права по аналогии, допускаемое и советским, и российским законодательством, возможно, следует рассматривать как элемент прецедентного регулирования. Западная доктрина рассматривает аналогию как разновидность прецедентного регулирования.

Review of John Gennari. 2006. Blowin’ Hot and Cool: Jazz and Its Critics. Chicago and London: University of Chicago Press

Publisher: name: Current Musicology
Year: 2007

description: John Gennari’s Blowin’ Hot and Cool: Jazz and Its Critics is a comprehensive history of American jazz criticism since the 1930s, centered on the foremost cultural achievement of the jazz critical field: “jazz’s canonization as an art”. The conceptual and historical framework of Blowin’ Hot and Cool: Jazz and Its Critics originated in Gennari’s 1991 article “Jazz Criticism: Its Development and Ideologies,” which was written at a time when the jazz canonization process still seemed incomplete. In the fifteen years or so since Gennari’s assessment, the canonization of jazz has been assure, largely because of the Jazz at Lincoln Center juggernaut and its affiliated critics and cultural output, but also through the intellectual work of what Gennari calls the “new interdisciplinary ‘jazz studies'”. In Blowin’ Hot and Cool, Gennari explains how “critics have been among the most important jazz mediators” between musicians and audiences.

description: The shapes of galaxy N-point correlation functions can be used as standard rulers to constrain the distance-redshift relationship and thence the expansion rate of the Universe. The cosmological density fields traced by late-time galaxy formation are initially nearly Gaussian, and hence all the cosmological information can be extracted from their 2-Point Correlation Function (2PCF) or its Fourier-space analog the power spectrum. Subsequent nonlinear evolution under gravity, as well as halo and then galaxy formation, generate higher-order correlation functions. Since the mapping of the initial to the final density field is, on large scales, invertible, it is often claimed that the information content of the initial field's power spectrum is equal to that of all the higher-order functions of the final, nonlinear field. This claim implies that reconstruction of the initial density field from the nonlinear field renders analysis of higher-order correlation functions of the latter superfluous. We here show that this claim is false when the N-point functions are used as standard rulers. Constraints available from joint analysis of the galaxy power spectrum and bispectrum (Fourier-space analog of the 3-Point Correlation Function) can, in some cases, exceed those offered by the initial power spectrum even when the reconstruction is perfect. We provide a mathematical justification for this claim and also demonstrate it using a large suite of N-body simulations. In particular, we show that for the z = 0 real-space matter field in the limit of vanishing shot noise, taking modes up to k_max = 0.2 h/Mpc, using the bispectrum alone offers a factor of two reduction in the variance on the cosmic distance scale relative to that available from the power spectrum.

description: We study the stability of topological order against local perturbations by considering the effect of a magnetic field on a spin model -- the toric code -- which is in a topological phase. The model can be mapped onto a quantum loop gas where the perturbation introduces a bare loop tension. When the loop tension is small, the topological order survives. When it is large, it drives a continuous quantum phase transition into a magnetic state. The transition can be understood as the condensation of `magnetic' vortices, leading to confinement of the elementary `charge' excitations. We also show how the topological order breaks down when the system is coupled to an Ohmic heat bath and discuss our results in the context of quantum computation applications.

description: We find a class of four dimensional deformed conformal field theories which appear extra dimensional when their gauge symmetries are spontaneously broken. The theories are supersymmetric moose models which flow to interacting conformal fixed points at low energies, deformed by superpotentials. Using a-maximization we give strong nonperturbative evidence that the hopping terms in the resulting latticized action are relevant deformations of the fixed point theories. These theories have an intricate structure of RG flows between conformal fixed points. Our results suggest that at the stable fixed points each of the bulk gauge couplings and superpotential hopping terms is turned on, in favor of the extra dimensional interpretation of the theory. However, we argue that the higher dimensional gauge coupling is generically small compared to the size of the extra dimension. In the presence of a brane the topology of the extra dimension is determined dynamically and depends on the numbers of colors and bulk and brane flavors, which suggests phenomenological applications. The RG flows between fixed points in these theories provide a class of tests of Cardy's conjectured a-theorem.

Electron teleportation between quantum dots using virtual dark exciton

description: We here propose a mechanism to teleport electrons between quantum dots through the transformation of a virtual bright exciton into a dark exciton. This mechanism relies on the interactions of two composite bosons: a pair of electrons with opposite spins, trapped in two dots and an electron-hole pair in a free exciton coupled to an unabsorbed pump pulse, which makes it ``bright'' but virtual. This bright exciton first turns ``dark'' by dropping its electron and stealing the trapped electron with opposite spin through an exchange Coulomb process with the trapped pair. In a second step, the dark exciton ``flies'' with its electron to the other dot where it turns bright again, by the inverse process. The ``Shiva diagrams'' for composite boson many-body effects that we have recently introduced, enlighten this understanding.

description: This collection of essays announces the assembly of music scholars who have incorporated disability studies into their research. Although the hybridization of disciplinary perspectives is hardly new, the careful preparatory arguments in the introduction and elsewhere throughout this collection nevertheless remind us of who the palpable schism between “tradition” music scholars and those who have embraced more liberally the intersections of music and cultural theory, literary criticism, gender, ethnicity, and sexuality. The seeming impenetrability that historical musicology and theory have represented in the past may well be further refuted by the addition of disability studies into the field of musical scholarship.

description: This paper investigates applications of eye tracking in transport aircraft design evaluations. Piloted simulations were conducted for a complete flight profile including take off, cruise and landing flight scenario using the transport aircraft flight simulator at CSIR National Aerospace Laboratories. Thirty-one simulation experiments were carried out with three pilots and engineers while recording the ocular parameters and the flight data. Simulations were repeated for high workload conditions like flying with degraded visibility and during stall. Pilots visual scan behaviour and workload levels were analysed using ocular parameters; while comparing with the statistical deviations from the desired flight path. Conditions for fatigue were also recreated through long duration simulations and signatures for the same from the ocular parameters were assessed. Results from the study found correlation between the statistical inferences obtained from the ocular parameters with those obtained from the flight path deviations. The paper also demonstrates an evaluators console that assists the designers or evaluators for better understanding of pilots attentional resource allocation.
Pergamon, Türkei. Ein großer Berg Arbeit? Konstruktionsprinzipien und Aufwand beim Bau des Yığma Tepe. Die Forschungsarbeiten von August bis Dezember 2022
Creators: name: Meinecke, Matthias
Publisher: name: e-Forschungsberichte des DAI
Year: 2023

description: Die Erdschüttungen von Tumuli konstituieren die Monumentalität der Grabform, sind aber erst in den letzten Jahrzehnten stärker beachtet worden. Am hellenistischen Yığma Tepe von Pergamon ist erkennbar, dass bestimmte Konstruktionsprinzipien angewendet wurden, die eine gute Kenntnis der Eigenschaften von Erdbaustoffen zeigen. Wie hoch der Aufwand für den Bau eines solchen Großtumulus war, lässt sich nur durch eine Schätzung unter Zuhilfenahme von Analogien im Rahmen der antiken Bauökonomie annäherungsweise bestimmen. Dadurch wird zwar ein hoher Aufwand für die Schüttung deutlich, der aber vor allem in den gewaltigen Dimensionen begründet ist. Insofern dürfen Erdbewegungen auch nicht überschätzt
werden, da sie einfach zu realisieren sind.

Living with Neighbors. III. The Origin of the Spin$-$Orbit Alignment of Galaxy Pairs: A Neighbor versus the Large-scale Structure

description: Recent observations revealed a coherence between the spin vector of a galaxy and the orbital motion of its neighbors. We refer to the phenomenon as "the spin$-$orbit alignment (SOA)" and explore its physical origin via the IllustrisTNG simulation. This is the first study to utilize a cosmological hydrodynamic simulation to investigate the SOA of galaxy pairs. In particular, we identify paired galaxies at $z = 0$ having the nearest neighbor with mass ratios from 1/10 to 10 and calculate the spin$-$orbit angle for each pair. Our results are as follows. (a) There exists a clear preference for prograde orientations (i.e., SOA) for galaxy pairs, qualitatively consistent with observations. (b) The SOA is significant for both baryonic and dark matter spins, being the strongest for gas and the weakest for dark matter. (c) The SOA is stronger for less massive targets and for targets having closer neighbors. (d) The SOA strengthens for galaxies in low-density regions, and the signal is dominated by central$-$satellite pairs in low-mass halos. (e) There is an explicit dependence of the SOA on the duration of interaction with its current neighbor. Taken together, we propose that the SOA witnessed at $z = 0$ has been developed mainly by interactions with a neighbor for an extended period of time, rather than tidal torque from the ambient large-scale structure.

Superfluid neutron star turbulence

Year: 2007

description: We analyse the implications of superfluid turbulence for neutron star physics. We begin by extending our previous results for the mutual friction force for a straight vortex array to account for the self-induced flow which arises when the vortices are curved. We then discuss Vinen's phenomenological model for isotropic turbulence, and derive the associated (Gorter-Mellink) form for the mutual friction. We compare this derivation to a more recent analysis of Schwarz, which sheds light on various involved issues. Having discussed isotropic turbulence, we argue that this case is unlikely to be relevant for neutron stars. Instead we expect a rotating neutron star to exhibit polarised turbulence, where relative flow drives the turbulence and rotation counteracts it. Based on recent results for superfluid Helium, we construct a phenomenological model that should have the key features of such a polarised turbulent system.

description: Two-dimensional transition metal dichalcogenides (TMDCs) integrated to photonic structures provide an intriguing playground for the development of novel optoelectronic devices with improved performance. Here, we show the enhanced light emission from TMDC based van der Waals heterostructures through coupling with microsphere cavities. We observe cavity-induced emission enhancement of TMDC materials which varies by an order of magnitude, depending on the size of the microsphere and thickness of the supporting oxide substrate. Furthermore, we demonstrate microsphere cavity-enhanced electroluminescence of van der Waals light emitting transistor, showing the potential of 2D material based hybrid optoelectronic structures.

description: В статье автор на исторических примерах античности, Нового времени и Новейшего времени исследует становление и развитие традиции разграничения прав человека на естественные и приобретенные, а также пяти поколений прав человека и основы становления шестого поколения прав человека (цифровых прав). Права и свободы личности (осмысленные, классифицированные в поколения прав человека) только тогда становятся реальностью, только тогда могут быть реализованы, когда гарантируются государством. Вся история юридической практики различных стран, включая и Россию, является подтверждением того, что реализация принятых законов гораздо более сложная задача, чем их декларация.
Children's conceptions of drama in education
Creators: name: Harpe, Sabina Dorothea
Publisher: name: University of British Columbia
Year: 2011

description: This study has been an investigation of children's views of drama in education. It invited children to reflect on the dramatic process as used by a classroom teacher in the context of integrated units of study. The specific research question addressed was: What are children's conceptions of drama when used by a non-specialist classroom teacher as an integral part of learning? Children, ages 10-12 years, were observed and then interviewed in a semi-structured manner. The data were analyzed according to the phenomenographical research methodology. This suited the intent of the study in that the aim of phenomenography is to discover and describe the world as seen by participants. The results were presented in the form of conceptions which are descriptions representing the various ways people view, experience or conceptualize their experiences. Seven such conceptions, falling into three different groups, were discovered. The first group identified three ways in which children viewed drama as a purposeful strategy used by a teacher: (a) drama is a tool, (b) drama is a way of linking, and (c) drama is a novel way of teaching. The second group identified three ways in which children viewed themselves participating in the dramatic process: (a) drama is something one must take part in, (b) drama is play, and (c) drama takes on a life of its own. The third group dealt with one specific area of drama and identified role taking as being like the donning of a cloak. Insights from the study centered around three major observations: (a) the importance of understanding the meaning making of learners, (b) the importance of reflection, and (c) the power of drama in education as an educational strategy. Implications for educators and recommendations for further research were derived from these themes.
