description: As the first intrinsic antiferromagnetic topological insulator, MnBi$_2$Te$_4$ has provided a platform to investigate the interplay of band topology and magnetism as well as the emergent phenomena arising from such an interplay. Here we report the chemical-vapor-transport (CVT) growth and characterization of MnBi$_2$Te$_4$, as well as the observation of the field-induced quantized Hall conductance in 6-layer devices. Through comparative studies between our CVT-grown and flux-grown MnBi$_2$Te$_4$ via magnetic, transport, scanning tunneling microscopy, and angle-resolved photoemission spectroscopy measurements, we find that CVT-grown MnBi$_2$Te$_4$ is marked with higher Mn occupancy on the Mn site, slightly higher Mn$_{\rm{Bi}}$ antisites, smaller carrier concentration and a Fermi level closer to the Dirac point. Furthermore, a 6-layer device made from the CVT-grown sample shows by far the highest mobility of 2500 cm$^2$V$\cdot$s in MnBi$_2$Te$_4$ devices with the quantized Hall conductance appearing at 1.8 K and 8 T. Our study provides a new route to obtain high-quality single crystals of MnBi$_2$Te$_4$ that are promising to make superior devices and realize emergent phenomena, such as the layer Hall effect and quantized anomalous hall effect, etc.

Dipole-dipole interaction between orthogonal dipole moments in time-dependent geometries

Year: 2007
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: In two nearby atoms, the dipole-dipole interaction can couple transitions with orthogonal dipole moments. This orthogonal coupling accounts for a number of interesting effects, but strongly depends on the geometry of the setup. Here, we discuss several setups of interest where the geometry is not fixed, such as particles in a trap or gases, by averaging over different sets of geometries. Two averaging methods are compared. In the first method, it is assumed that the internal electronic evolution is much faster than the change of geometry, whereas in the second, it is vice versa. We find that the orthogonal coupling typically survives even extensive averaging over different geometries, albeit with qualitatively different results for the two averaging methods. Typically, one- and two-dimensional averaging ranges modelling, e.g., low-dimensional gases, turn out to be the most promising model systems.

description: A dark Friedman-Robertson-Walker fluid governed by a non-linear inhomogeneous equation of state is considered which can be viewed as a conveniently simple paradigm for a whole class of models which exhibit phase transitions from a non-phantom towards a phantom era (superacceleration transition). From another side, such dark fluid models may describe also quintessence-like cosmic acceleration. Thermodynamical considerations for the processes involved, which are of great importance in the characterization of the global evolution of the corresponding universe, are given too. Connecting the proposed equation of state with an anisotropic Kasner universe with viscosity, we are led to the plausible conjecture of a dark fluid origin of the anisotropies in the early universe.

subject: Three-River Headwater Region, Ecological environment, Humanistic environment, Topographic heterogeneity

description: The ecological environment of the Three-River Headwater Region is primitive and unique, and sensitive and complex to external influences. The Three-River Headwater Region is the largest nature reserve in China, and is also a nature reserve with the highest concentration of biodiversity in the world’s high-altitude areas, so the protection of ecological diversity in this region is particularly important. Ecological diversity is the material basis on which the entire humanity depends to survive and develop. It not only provides humans with basic needs such as food, energy and materials, and is also extremely important for maintaining ecological balance, regulating the climate and promoting the sustainable development of the region. Studying the topographical heterogeneity of the region is first of all a true grasp of the topography of the region, which has certain guiding significance for people's production and life. In addition, studying the impact of topographical heterogeneity on the climate of the region will help to study the formation and variation of regional climate.

description: The replica wormholes are a key to the existence of the islands that play a central role in a recent proposal for the resolution of the black hole information paradox. In this paper, we study the replica wormholes in the JT gravity, a model of two-dimensional quantum gravity coupled to a non-dynamical dilaton, by making use of the 2$d$ conformal field theory (CFT) description, namely, the Liouville theory coupled to the $(2,p)$ minimal matter in the $p\to\infty$ limit. In the Liouville CFT description, the replica wormholes are created by the twist operators and the gravitational part of the bulk entanglement entropy can be reproduced from the twist operator correlators. We propose the precise dictionary and show how this correspondence works in detail.

Naturalistic antecedent control as a positive factor in the generalisation of newly acquired "play" behaviors in autistic children
Creators: name: Woods, Thomas Sheldon
Publisher: name: University of British Columbia
Year: 2010

description: Four developmentally handicapped (autistic) boys in a treatment centre for behavior disordered children were taught to perform colouring and block-assembly "play" responses within the discrete trial format training paradigm. Two specific training strategies were compared, one using naturalistic, materials-presentation antecedent cues, and the other contrived, verbal ones. Generalisation across comparable tasks with only naturalistic cueing was probed. Findings indicated that, with all participants, the choice of antecedent cues for training which were found in the generalisation condition was strongly related to the degree to which learning carried over. These results are discussed in context of a behavioural contrast account of failures to generalise, and suggestions for future remedial practice based upon the related topics of behavioural contrast and antecedent control are offered.

description: Following the introduction of the concepts of apathy, sympathy, empathy, metapathy, and their correspondence with emotioncy, the present study aimed to present the concept of transpathy, and its respective type of concern, transvolvement, as the highest level of concern about others. Additionally, it sought to investigate which types of emotions are typically experienced with different concern types, and which one is deemed as the most desirable one among students. As the first step, five different scenarios measured the emotions experienced by each type of concern (i.e., apathy, sympathy, empathy, metapathy, and transpathy). The scenarios’ validity was verified with the consolation of professionals. The data obtained from 104 participants revealed that transpathy enjoys the highest percentage of positive emotions, and subsequently, transpathic teachers are deemed as the most successful ones. However, despite being overly concerned, negative emotions were also attributed to metapathatic and transpathic teachers, reaffirming the friction previously mentioned in studies.
Initial correlations in nonequilibrium Falicov-Kimball model
Creators: name: Tran, Minh-Tien
Publisher: name: arXiv
Year: 2008
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: The Keldysh boundary problem in a nonequilibrium Falicov-Kimball model in infinite dimensions is studied within the truncated and self-consistent perturbation theories, and the dynamical mean-field theory. Within the model the system is started in equilibrium, and later a uniform electric field is turned on. The Kadanoff-Baym-Wagner equations for the nonequilibrium Green functions are derived, and numerically solved. The contributions of initial correlations are studied by monitoring the system evolution. It is found that the initial correlations are essential for establishing full electron correlations of the system and independent on the starting time of preparing the system in equilibrium. By examining the contributions of the initial correlations to the electric current and the double occupation, we find that the contributions are small in relation to the total value of those physical quantities when the interaction is weak, and significantly increase when the interaction is strong. The neglect of initial correlations may cause artifacts in the nonequilibrium properties of the system, especially in the strong interaction case.

description: The Rastall theory of gravity is the generalized form of the Einstein theory which describes the conservation law of energy and momentum tensor. In our work, we compute the charged black strings solution in the background of Rastall theory by applying the Newman-Janis approach. After computing the charged black strings solution in the background of Rastall theory, we study the thermodynamical property (i.e., Hawking temperature) for the charged black strings. Furthermore, we investigate the graphical representation of Hawking temperature via event horizon to check the stability conditions of charged black strings under the influence of Rastall theory. Moreover, we examine the modified Hawking temperature for charged black strings in Rastall theory by taking into account the quantum gravity effects. We also discuss the physical state of charged black strings under the effects of quantum gravity and spin parameter (appears due to Rastall theory in charged black strings solution).

Cephalopods with longiconic orthoconic or weakly cyrtoconic conchs, with cyrtoconic or coiled apical part. Siphuncle tubular, narrow (up to 0.20 of whorl height). Septal necks straight (orthochoanitic), rarely cyrtochoanitic in apical conch parts, and long (usually 0.25–0.30 of chamber length but over 0.50 in some taxa). Connecting rings often disaggregated and covered with cameral deposits that extend to cover the septal neck and inner parts of the connecting ring. Cameral deposits often consist of longitudinal lamellae or sheets that longitudinally divide chambers. Initial chamber small (length = 0.4 mm), subspherical, without cicatrix (after Kröger et al. 2007, emended).

description: We consider entanglement entropies of finite spatial intervals in Minkowski radiation baths coupled to the eternal black hole in JT gravity, and the related problem involving free fermion BCFT in the thermofield double state. We show that the non-monotonic entropy evolution in the black hole problem precisely matches that of the free fermion theory in a high temperature limit, and the results have the form expected for CFTs with quasiparticle description. Both exhibit rich behaviour that involves at intermediate times, an entropy saddle with an island in the former case, and in the latter a special class of disconnected OPE channels. The quantum extremal surfaces start inside the horizon, but can emerge from and plunge back inside as time evolves, accompanied by a characteristic dip in the entropy also seen in the free fermion BCFT. Finally an entropy equilibrium is reached with a no-island saddle.

description: Exploiting the full computational power of always deeper hierarchical multiprocessor machines requires a very careful distribution of threads and data among the underlying non-uniform architecture. The emergence of multi-core chips and NUMA machines makes it important to minimize the number of remote memory accesses, to favor cache affinities, and to guarantee fast completion of synchronization steps. By using the BubbleSched platform as a threading backend for the GOMP OpenMP compiler, we are able to easily transpose affinities of thread teams into scheduling hints using abstractions called bubbles. We then propose a scheduling strategy suited to nested OpenMP parallelism. The resulting preliminary performance evaluations show an important improvement of the speedup on a typical NAS OpenMP benchmark application.

description: We have developed a microcavity single-photon source based on a single quantum dot within a planar cavity in which wet-oxidation of a high-aluminium content layer provides lateral confinement of both the photonic mode and the injection current. Lateral confinement of the optical mode in optically pumped structures produces a strong enhancement of the radiative decay rate. Using microcavity structures with doped contact layers, we demonstrate a single-photon emitting diode where current may be injected into a single dot.

description: We constructed the most general N=4 superconformal 3-particles systems with translation invariance. In the basis with decoupled center of mass the supercharges and Hamiltonian possess one arbitrary function which defines all potential terms. We have shown that with the proper choice of this function one may describe the standard, $A_2$ Calogero model as well as $BC_2, B_2,C_2$ and $D_2$ Calogero models with N=4 superconformal symmetry. The main property of all these systems is that even with the coupling constant equal to zero they still contain nontrivial interactions in the fermionic sector. In other words, there are infinitely many non equivalent N=4 supersymmetric extensions of the free action depending on one arbitrary function. We also considered quantization and explicitly showed how the supercharges and Hamiltonian are modified.

description: In this report, we discuss the dynamics of photons in a five-dimensional Schwarzschild black hole. We find that the corresponding Eddington-Finkelstein-like coordinate admits two time-coordinate singularities for a particular condition. This condition is due to the existence of a non-zero angular momentum related to the extra spatial dimension. By introducing a new Regge-Wheeler tortoise coordinate, both singularities can be removed from the Eddington-Finkelstein-like coordinate. It is identified that the additional singularity is related to the photon sphere in a hyperplane, and we analyze it using a dynamical system approach. Simulation results of photon motion based on numerical calculation are presented. It is suggested that the related bending motion characteristic can probably be considered as a signature for probing the existence of the extra spatial dimension.

description: One of the most important tasks in high energy physics is search for the exotic states, such as glueball, hybrid and multi-quark states. The transitions $ψ(ns)\to ψ(ms)+ππ$ and $Υ(ns)\to Υ(ms)+ππ$ attract great attentions because they may reveal characteristics of hybrids. In this work, we analyze those transition modes in terms of the theoretical framework established by Yan and Kuang. It is interesting to notice that the intermediate states between the two gluon-emissions are hybrids, therefore by fitting the data, we are able to determine the mass spectra of hybrids. The ground hybrid states are predicted as 4.23 GeV (for charmonium) and 10.79 GeV (for bottonium) which do not correspond to any states measured in recent experiments, thus it may imply that very possibly, hybrids mix with regular quarkonia to constitute physical states. Comprehensive comparisons of the potentials for hybrids whose parameters are obtained in this scenario with the lattice results are presented.

Validation of the WISC-R for grade two French immersion students
Creators: name: Neilsen, Barbara Jean
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of the present study was to investigate the appropriateness of the use of the Wechsler Intelligence Scale for Children-Revised (WISC-R) for assessment of French immersion students whose language of instruction at school has been solely French. To investigate this problem, the WISC-R performance of 29 grade two French immersion students was compared to that of 29 regular (English) program peers. The rationale for the present study was based on the fact that the WISC-R has been commonly administered to French immersion children and interpreted as if this group of children were identical to the population on whom the test was standardized. While previous research has indicated that British Columbia students attain higher WISC-R means and less variance than American students, no data were available to suggest how the performance of this linguistically different group, French immersion students, compared to that of students who received all formal education in their first language, English. All students obtained parental consent to participate in the study, came from homes in which English was the dominant language, and had been continuously enrolled from kindergarten through the end of grade two in their current academic programs. Groups were matched for gender and educational level of the head of the household. All testing and scoring were done by graduate students who had been trained and supervised in the use of the WISC-R. A multivariate analysis of variance was used to test the hypotheses of equal means and variances between the two groups on the 12 subtests and the Verbal and Performance factors. A univariate analysis was used to test the hypotheses of equal Full Scale means and variances between groups. Comparative results indicated that the central tendancies and variance-covariance structure for both the French immersion and the regular program groups, matched for educational level of parents, were essentially the same. Both the immersion and regular program groups had Verbal, Performance and Full Scale IQs in Wechsler's High Average category. Results of an ancillary analysis indicated that the 58 children in the present study had significantly higher Full Scale IQs than did a more representative British Columbia sample whose mean IQs were significantly higher than those published in the WISC-R manual. It was concluded that although interpretation of the results is confounded by possible initial differences between groups, the use of the WISC-R appears not to be disadvantageous to higher SES French immersion children whose main language of the home is English. Further, it was concluded that, for British Columbia children, use of the British Columbia norms for the age groups, 7½, 9½ and 11½ is more appropriate than use of the 1974 Wechsler norms.
Measuring stellar magnetic fields with the low resolution spectropolarimeter of the William Herschel Telescope
Creators: name: Leone, F.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Despite the influence of magnetic fields on the structure and evolution of stars is largely demonstrated from the theoretical point of view, their observational evidence in non-degenerated stars is still rather scanty and mainly circumscribed to bright objects (V<10). Stellar magnetic fields are commonly measured on the basis of circular spectropolarimetry at high/middle resolution across the profile of metal lines. The present sensitivity of telescopes and spectrographs makes this still an almost prohibitive method for faint stars. In principle, stellar magnetic fields can be also measured on the basis of low resolution spectropolarimetry, with very important results obtained at the 8 m ESO telescopes with FORS1. The trade off between S/N and spectral resolution in measuring stellar magnetic fields justify an attempt, here presented, to perform these measurements at the 4.5 m William Herschel Telescope. HD3360, one of the stars with the weakest known magnetic field, and the magnetic chemically peculiar stars HD10783, HD74521 and HD201601 have been observed with the spectropolarimeter ISIS in the 3785-4480 A range. Measured stellar magnetic fields, from Stokes I and V spectra with S/N > 600, show an internal error of <50 G selecting the whole interval and <200 G within a Balmer line. Ripples in the Stokes V spectra of HD3360 result in an instrumental positive magnetic field certainly not larger than 80 G.

description: Recently, many arbitrary-oriented object detection (AOOD) methods have been proposed and attracted widespread attention in many fields. However, most of them are based on anchor-boxes or standard Gaussian heatmaps. Such label assignment strategy may not only fail to reflect the shape and direction characteristics of arbitrary-oriented objects, but also have high parameter-tuning efforts. In this paper, a novel AOOD method called General Gaussian Heatmap Label Assignment (GGHL) is proposed. Specifically, an anchor-free object-adaptation label assignment (OLA) strategy is presented to define the positive candidates based on two-dimensional (2-D) oriented Gaussian heatmaps, which reflect the shape and direction features of arbitrary-oriented objects. Based on OLA, an oriented-bounding-box (OBB) representation component (ORC) is developed to indicate OBBs and adjust the Gaussian center prior weights to fit the characteristics of different objects adaptively through neural network learning. Moreover, a joint-optimization loss (JOL) with area normalization and dynamic confidence weighting is designed to refine the misalign optimal results of different subtasks. Extensive experiments on public datasets demonstrate that the proposed GGHL improves the AOOD performance with low parameter-tuning and time costs. Furthermore, it is generally applicable to most AOOD methods to improve their performance including lightweight models on embedded platforms.

description: The possibility of having an extension of the cosmological standard model with a Hubble expansion rate $H$ constrained to a finite interval is considered. Two periods of accelerated expansion arise naturally when the Hubble expansion rate approaches to the two limiting values. The new description of the history of the universe is confronted with cosmological data and with several theoretical ideas going beyond the standard cosmological model.

description: In image retrieval, standard evaluation metrics rely on score ranking, e.g. average precision (AP). In this paper, we introduce a method for robust and decomposable average precision (ROADMAP) addressing two major challenges for end-to-end training of deep neural networks with AP: non-differentiability and non-decomposability. Firstly, we propose a new differentiable approximation of the rank function, which provides an upper bound of the AP loss and ensures robust training. Secondly, we design a simple yet effective loss function to reduce the decomposability gap between the AP in the whole training set and its averaged batch approximation, for which we provide theoretical guarantees. Extensive experiments conducted on three image retrieval datasets show that ROADMAP outperforms several recent AP approximation methods and highlight the importance of our two contributions. Finally, using ROADMAP for training deep models yields very good performances, outperforming state-of-the-art results on the three datasets.
Bianchi Model CMB Polarization and its Implications for CMB Anomalies

description: We derive the CMB radiative transfer equation in the form of a multipole hierarchy in the nearly-Friedmann-Robertson-Walker limit of homogeneous, but anisotropic, universes classified via their Bianchi type. Compared with previous calculations, this allows a more sophisticated treatment of recombination, produces predictions for the polarization of the radiation, and allows for reionization. Our derivation is independent of any assumptions about the dynamical behaviour of the field equations, except that it requires anisotropies to be small back to recombination; this is already demanded by observations. We calculate the polarization signal in the Bianchi VIIh case, with the parameters recently advocated to mimic the several large-angle anomalous features observed in the CMB. We find that the peak polarization signal is ~ 1.2 micro K for the best-fit model to the temperature anisotropies, and is mostly confined to multipoles l<10. Remarkably, the predicted large-angle EE and TE power spectra in the Bianchi model are consistent with WMAP observations that are usually interpreted as evidence of early reionization. However, the power in B-mode polarisation is predicted to be similar to the E-mode power and parity-violating correlations are also predicted by the model; the WMAP non-detection of either of these signals casts further strong doubts on the veracity of attempts to explain the large-angle anomalies with global anisotropy. On the other hand, given that there exist further dynamical degrees of freedom in the VIIh universes that are yet to be compared with CMB observations, we cannot at this time definitively reject the anisotropy explanation.

Ejecta Exchange, Color Evolution in the Pluto System, and Implications for KBOs and Asteroids with Satellites

description: We examine the ability of impacts by Kuiper Belt debris to cause regolith exchange between objects in the Pluto system. We find that ejecta velocities from KB impacts are too low to escape from Pluto and Charon. However, ejecta can escape Nix and Hydra, and is capable of covering one another to depths as high as 10s of meters, and Charon and Pluto, perhaps to depths up to several 10s of cm. Although Pluto's annual atmospheric frost deposition cycle will cover such imported debris on timescales faster than it is emplaced, no such masking mechanism is available on Hydra, Nix, and Charon. As a result, ejecta exchange between these bodies is expected to evolve their colors, albedos, and other photometric properties to be similar. We examined the ability of ejecta exchange to work for other Kuiper Belt binaries and found the process can be effective in many cases. This process may also operate in asteroid binary systems.

description: Politikberatung erfreut sich einer immer größeren Bedeutung aber auch Aufmerksamkeit. Dabei ist diese Form der Beratung der politisch Verantwortlichen sehr unterschiedlich und wird durch verschiedene Stakeholder ermöglicht. Eine Besonderheit dabei ist die Beratung durch die Verwaltung. Insbesondere gilt dies für Berichte wie Verfassungsschutzberichte und Risikobilder als mögliches Beratungsinstrument. Beide Berichte stellen mögliche Informationen für Bedrohungen und zukünftige Herausforderungen dar. Inwiefern speziell diese Berichte im politischen Handeln berücksichtigt werden, wurde mittels Expert:inneninterviews versucht zu ergründen. Zuerst wurde das Forschungsfeld anhand der vorhandenen Literatur eingebettet und notwendige Begriffe definiert. Ebenfalls wurde der Policycycle und die Wirkungssteuerung im öffentlichen Dienst in Österreich für ein vertiefendes Verständnis von Zusammenhängen von Beratungsleistungen seitens der Verwaltung dargelegt. Durch die Analyse der Interviews konnte mit Blick auf die Theorie festgestellt werden, dass diese Berichte tatsächlich Berücksichtigung finden. Allerdings wurden ebenso Verbesserungsmöglichkeiten wie stärkere Interdisziplinarität oder eine einfache Lesbarkeit der Berichte erkannt. Darüber hinaus konnte festgestellt werden, dass klare Publikationsrichtlinien gewünscht wären und damit auch eine höhere Transparenz sichergestellt werden könnte.
description: The field of political consulting is gaining increasing significance and attention. The advice provided to political decision-makers in this realm varies widely and involves collaboration with diverse stakeholders. A notable aspect is the counsel provided by administrative bodies, particularly in reports like those addressing constitutional protection and risk assessments. These reports offer potential insights into threats and forthcoming challenges. The degree to which these reports impact political decision-making was explored through expert interviews. Initially, the research field was contextualized using existing literature, and essential terms were defined. Additionally, the policy cycle and impact control within the public service in Austria were elucidated to enhance understanding of the connections between advisory services offered by the administration. The analysis of the interviews revealed that, in accordance with theoretical expectations, these reports are indeed taken into consideration. Nevertheless, areas for improvement, such as fostering greater interdisciplinary collaboration and enhancing the readability of these reports, were also identified. Moreover, the need for clear publication guidelines was highlighted, aiming to enhance transparency.
A Finite Semantics of Simply-Typed Lambda Terms for Infinite Runs of
 Automata

description: Model checking properties are often described by means of finite automata. Any particular such automaton divides the set of infinite trees into finitely many classes, according to which state has an infinite run. Building the full type hierarchy upon this interpretation of the base type gives a finite semantics for simply-typed lambda-trees. A calculus based on this semantics is proven sound and complete. In particular, for regular infinite lambda-trees it is decidable whether a given automaton has a run or not. As regular lambda-trees are precisely recursion schemes, this decidability result holds for arbitrary recursion schemes of arbitrary level, without any syntactical restriction.

description: The discovery of community structure is a common challenge in the analysis of network data. Many methods have been proposed for finding community structure, but few have been proposed for determining whether the structure found is statistically significant or whether, conversely, it could have arisen purely as a result of chance. In this paper we show that the significance of community structure can be effectively quantified by measuring its robustness to small perturbations in network structure. We propose a suitable method for perturbing networks and a measure of the resulting change in community structure and use them to assess the significance of community structure in a variety of networks, both real and computer generated.
