description: We use computer simulations to probe the thermodynamic and dynamic properties of a glass-former that undergoes an ideal glass-transition because of the presence of randomly pinned particles. We find that even deep in the equilibrium glass state the system relaxes to some extent because of the presence of localized excitations that allow the system to access different inherent structures, giving thus rise to a non-trivial contribution to the entropy. By calculating with high accuracy the vibrational part of the entropy, we show that also in the equilibrium glass state thermodynamics and dynamics give a coherent picture and that glasses should not be seen as a disordered solid in which the particles undergo just vibrational motion but instead as a system with a highly nonlinear internal dynamics.

Counteroffers and Efficiency in Labor Markets With Asymmetric Information

description: This paper considers the effect of offer matching on labor market outcomes when the current employer has better information about his worker’s productivity than potential employers. Previous research found that when current employers have better information than potential employers, the later use job assignment to infer an employed worker’s qualifications. As a result, assignment of workers to jobs is inefficient. I find that when current employers can match outside offers the equilibrium outcome may be efficient despite the asymmetric information. I then analyze the effect of the asymmetric information on investment in human capital made by employers and workers, and find these investment levels to be first best.
Estimates of multipolar coefficients to search for cosmic ray anisotropies with non-uniform or partial sky coverage

description: We study the possibility to extract the multipolar moments of an underlying distribution from a set of cosmic rays observed with non-uniform or even partial sky coverage. We show that if the degree is assumed to be upper bounded by $L$, each multipolar moment can be recovered whatever the coverage, but with a variance increasing exponentially with the bound $L$ if the coverage is zero somewhere. Despite this limitation, we show the possibility to test predictions of a model without any assumption on $L$ by building an estimate of the covariance matrix seen through the exposure function.

description: Quantum phase transition in topological insulators has drawn heightened attention in condensed matter physics and future device applications. Here we report the magnetotransport properties of single crystalline (Bi0.92In0.08)2Se3. The average mobility of about 1000 cm2/Vs is obtained from the Lorentz law at the low field up to 50 K. The quantum oscillations rise at a field of about 5 T, revealing a high mobility of 1.4*10^4 cm2/Vs at 2 K. The topological Dirac fermions are evident by the nontrivial Berry phase in the Landau Fan diagram. The properties make the (Bi0.92In0.08)2Se3 a promising platform for the investigation of quantum phase transition in topological insulators.

description: The properties of higher-dimensional black holes can differ significantly from those of black holes in four dimensions, since neither the uniqueness theorem, nor the staticity theorem or the topological censorship theorem generalize to higher dimensions. We first discuss black holes of Einstein-Maxwell theory and Einstein-Maxwell-Chern-Simons theory with spherical horizon topology. Here new types of stationary black holes are encountered. We then discuss nonuniform black strings and present evidence for a horizon topology changing transition.

Systematic investigation of the structure of the Si(553)-Au surface from first principles

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: We present here a comprehensive search for the structure of the Si(553)-Au reconstruction. More than two hundred different trial structures have been studied using first-principles density-functional calculations with the SIESTA code. An iterative procedure, with a step-by-step increase of the accuracy and computational cost of the calculations, was used to allow for the study of this large number of configurations. We have considered reconstructions restricted to the topmost bilayer and studied two types: i) "flat" surface-bilayer models, where atoms at the topmost bilayer present different coordinations and registries with the underlying bulk, and ii) nine different models based on the substitution of a silicon atom by a gold atom in different positions of a $π$-bonded chain reconstruction of the Si(553) surface. We have developed a compact notation that allows us to label and identify all these structures. This is very useful for the automatic generation of trial geometries and counting the number of inequivalent structures, i.e., structures having different bonding topologies. The most stable models are those that exhibit a honeycomb-chain structure at the step edge. One of our models (model f2) reproduces the main features of the room temperature photoemission and scanning-tunneling microscopy data. Thus we conclude that f2 structure is a good candidate for the high temperature structure of the Si(553)-Au surface.

description: The field of plasmonics seeks to find materials with an intensive plasmon (large plasmon pole weight) with low Landau, phonon and other losses (small decay width). In this paper we propose a new class of materials that show exceptionally good plasmonic properties. These materials consist of van der Waals stacked 'plasmon active' layers (atomically thin metallic layers) and 'supporting' layers (atomically thin wide band gap insulating layers). One such material that can be experimentally realized - lithium intercalated hexagonal boron-nitride is studied in detail. We show that its 2D plasmon intensity is superior to intensity of well studied Dirac plasmon in heavy doped graphene which is hard to achieve. We also propose the method for computationally very cheap, but accurate analysis of plasmon spectra in such materials, based on one band tight-binding approach and effective background dielectric function.
Structure and bonding of water molecules in zeolite hosts: Benchmarking plane-wave DFT against crystal structure data

description: Density-functional theory (DFT) calculations are widely employed to study the interaction of water molecules with zeolite frameworks. However, there have been only few attempts to assess whether these computations reproduce experimental structure data sufficiently well, especially with regard to the hydrogen positions of the water molecules. In this work, a detailed comparison between experimental crystal structures and DFT-optimised structures is made for six water-loaded natural zeolites. For each system, high-quality structure determinations from neutron diffraction data have been reported (bikitaite/Li–BIK, edingtonite/Ba–EDI, gismondine/Ca–GIS, scolecite/Ca–NAT, natrolite/Na–NAT, yugawaralite/Ca–YUG). Using a plane-wave DFT approach, the performance of six pure and three dispersion-corrected exchange-correlation functionals is compared, focusing on an optimisation of the atomic coordinates in a fixed unit cell (with cell parameters taken from experiment). It is found that the PBE and the PW91 functional give the smallest overall deviation between experiment and computation. Of the dispersion-corrected approaches, the PBE–TS functional exhibits the best performance. For the PBE and PBE–TS functionals, the agreement between experiment and DFT is analysed in more detail for different groups of interatomic distances. Regarding the OW–H distances in the water molecules, the DFT optimisations lead to physically realistic bond lengths. On the other hand, DFT has a systematic tendency to underestimate the length of hydrogen bonds. The cation-oxygen distances are mostly in very good agreement with experiment, although some exceptions indicate the necessity of further studies.

description: CARMENES is a spectrograph built for the 3.5 m telescope at the Calar Alto Observatory. The main aim is to detect low mass planets around M dwarfs. In order to achieve this goal, it is critical to characterize the monitored stars, especially their activity and rotation. Using Quick-Look Pipeline TESS data from its first two cycles, we studied the rotation and activity in the 2-min cadence time series of 1249 M dwarfs in the CARMENES input catalog. Next, with generalised Lomb-Scargle (GLS) periodograms, we measured 231 rotation periods between 0.11 d and 10.52 d. Of them, 147 are consistent with their literature counterparts and 74 were previously unknown. Using splines and Fourier polynomials, we detrended the light curves of the stars for which we found a rotational period in order to look for flaring activity. We measured energies between \( 10^{30}\) erg and \(10^{35}\) erg of 1922 flares of 225 periodic M dwarfs. We fitted the cumulative frequency distribution of flares with energies greater than \(10^{33}\) erg to a power law of the form \(NdE∝E^{-\alpha}dE\) and determined \(\alpha = 2.119^{+0.075}_{-0.105}\). We also found α to increase for later spectral types.

description: We study symmetry breaking and gap generation for fermions in the 2D space of constant negative curvature (the Lobachevsky plane) in an external covariantly constant magnetic field in a four-fermion model. It is shown that due to the magnetic and negative curvature catalysis phenomena the critical coupling constant is zero and there is a symmetry breaking condensate in the chiral limit even in free theory. We analyze solutions of the gap equation in the cases of zero, weak, and strong magnetic fields. As a byproduct we calculate the density of states and the Hall conductivity for noninteracting fermions that may be relevant for studies of graphene.

description: We study an interacting two-component hard-core bosons on square lattice for which, in the presence of staggered magnetic flux, the ground state is a bosonic integer quantum Hall (BIQH) state. Using a coupled-wire bosonization approach, we analytically show this model exhibits a BIQH state at total charge half filling associated with a symmetry-protected topological phase under $U(1)$ charge conservation. These theoretical expectations are verified, using the infinite density matrix renormalization group method, by providing numerical evidences for: (i) a quantized Hall conductance $σ_{xy}=\pm2$, and (ii) two counter-propagating gapless edge modes. Our model is a bosonic cousin of the fermionic Haldane model and serves as an additional case of analogy between bosonic and fermionic quantum Hall states.

description: This article discusses the application of thermoelectric (TE) materials in building facade systems, which can be used to create active exterior enclosures. TEs are semiconductors that have the ability to produce a temperature gradient when electricity is applied, exploiting the Peltier effect, or to generate a voltage when exposed to a temperature gradient, utilizing the Seebeck effect. TEs can be used for heating, cooling, or electricity generation. In this research, heating and cooling applications of these novel systems were explored. We designed and constructed two prototypes, where one prototype was used to study integration of TE modules (TEMs) as stand-alone elements in the facade, and one prototype was used to explore integration of TEMs and heat sinks in facade assemblies. Both prototypes were tested for heating and cooling potential, using a thermal chamber to represent four different exterior environmental conditions (−18°,−1°,16°, and 32°C). The interior ambient conditions were kept constant at room temperature. The supplied voltage to facade-integrated TEMs varied from 1 to 8 V. We measured temperature outputs of TEMs for all investigated thermal conditions using thermal imaging, which are discussed in this article. The results indicate that while stand-alone facade-integrated TEMs are not stable, addition of heat sinks improves their performance drastically. Facade-integrated TEMs with heatsinks showed that they would operate well in heating and cooling modes under varying exterior environmental conditions.

description: Due to the infrared problem of high-temperature field theory, a robust study of the electroweak phase transition (EWPT) requires use of non-perturbative methods. We apply the method of high-temperature dimensional reduction to the two Higgs doublet model (2HDM) to obtain three-dimensional effective theories that can be used for non-perturbative simulations. A detailed derivation of the mapping between the full four-dimensional and the effective three-dimensional theories is presented. The results will be used in future lattice studies of the 2HDM. In the limit of large mass mixing between the doublets, existing lattice results can be recycled. The results of such a study are presented in a companion paper.

We derive analytically the asymptotic behavior of the solutions and confirm it numerically by solving the field equations. Finally, we show that these solutions can be embedded in realistic theories like the two-doublet extension of the standard model.

description: The Sentinel-2 satellite mission delivers multi-spectral imagery with 13 spectral bands, acquired at three different spatial resolutions. The aim of this research is to super-resolve the lower-resolution (20 m and 60 m Ground Sampling Distance - GSD) bands to 10 m GSD, so as to obtain a complete data cube at the maximal sensor resolution. We employ a state-of-the-art convolutional neural network (CNN) to perform end-to-end upsampling, which is trained with data at lower resolution, i.e., from 40->20 m, respectively 360->60 m GSD. In this way, one has access to a virtually infinite amount of training data, by downsampling real Sentinel-2 images. We use data sampled globally over a wide range of geographical locations, to obtain a network that generalises across different climate zones and land-cover types, and can super-resolve arbitrary Sentinel-2 images without the need of retraining. In quantitative evaluations (at lower scale, where ground truth is available), our network, which we call DSen2, outperforms the best competing approach by almost 50% in RMSE, while better preserving the spectral characteristics. It also delivers visually convincing results at the full 10 m GSD. The code is available at https://github.com/lanha/DSen2

description: We present a self-consistent Schroedinger-Poisson scheme for simulation of electrostatic quantum dots defined in gated two-dimensional electron gas formed at n-AlGaAs/GaAs heterojunction. The computational method is applied to a quantitative description of transport properties studied experimentally by Elzermann et al. [Appl. Phys. Lett. {\bf 84}, 4617 (2004)]. The three-dimensional model describes the electrostatics of the entire device with a quantum dot that changes shape and floats inside a gated region when the applied voltages are varied. Our approach accounts for the metal electrodes of arbitrary geometry and configuration, includes magnetic field applied perpendicular to the growth direction, electron-electron correlation in the confined electron system and its interaction with the electron reservoir surrounding the quantum dot. We calculate the electric field, the space charge distribution as well as energies and wave functions of confined electrons to describe opening of two transport channels between the reservoir and the confined charge puddle. We determine the voltages for charging the dot with up to 4 electrons. The results are in a qualitative and quantitative agreement with the experimental data.

description: Density-functional theory (DFT) calculations incorporating a pairwise dispersion correction were employed to optimize the structures of various neutral-framework compounds with zeolite topologies. The calculations used the PBE functional for solids (PBEsol) in combination with two different dispersion correction schemes, the D2 correction devised by Grimme and the TS correction of Tkatchenko and Scheffler. In the first part of the study, a benchmarking of the DFT-optimized structures against experimental crystal structure data was carried out, considering a total of 14 structures (8 all-silica zeolites, 4 aluminophosphate zeotypes, and 2 dense phases). Both PBEsol-D2 and PBEsol-TS showed an excellent performance, improving significantly over the best-performing approach identified in a previous study (PBE-TS). The temperature dependence of lattice parameters and bond lengths was assessed for those zeotypes where the available experimental data permitted such an analysis. In most instances, the agreement between DFT and experiment improved when the experimental data were corrected for the effects of thermal motion and when low-temperature structure data rather than room-temperature structure data were used as a reference. In the second part, a benchmarking against experimental enthalpies of transition (with respect to α-quartz) was carried out for 16 all-silica zeolites. Excellent agreement was obtained with the PBEsol-D2 functional, with the overall error being in the same range as the experimental uncertainty. Altogether, PBEsol-D2 can be recommended as a computationally efficient DFT approach that simultaneously delivers accurate structures and energetics of neutral-framework zeotypes.

description: As expenditures on health continue to increase it becomes important to determine the effectiveness of health care programs. In this paper we outline an approach to evaluating health care programs with particular emphasis on preventive programs. We argue that the most important and most difficult step in the process is assessing the differential impact a measure has on health status. Some specific programs including environmental control, the search for healthful life-styles, and screening programs are briefly considered.

We argue that, if these predictions turn out to be correct, either these quantities are insensitive to the state of matter created in high energy heavy ion collisions or the observed simplicity and universality of the data must be telling us something profound about the mechanism of particle production, which to this date is not well understood.

description: Variations in the chemical structures of kerogens From highly volatile bituminous coal located near two igneous dike intrusions in the Illinois Basin were examined in detail by advanced solid-state 13C nuclear magnetic resonance (NMR) spectroscopy. Spectral-editing techniques were used to identify specific functional groups. Direct polarization was used to quantify different functional groups. 1H-13C two- dimensional heteronuclear NMR was used to examine connectivities and proximities, and 1H-13C long-range recoupled dipolar dephasing was used to estimate aromatic cluster sizes. With decreasing distance to dike contacts and increasing thermal maturity (vitrinite reflectance R0 from 0.62% to 5.03%), new insights into the chemical structural changes in coal kerogens include (i) the C(CH2)C groups were removed faster than CCH3 groups, suggesting that the major cleavage of aliphatics should not occur at aryl rings, (ii) a progressive decrease of the relative abundance of protonatcd aromatic carbons, possibly due to replacement of aromatic hydrogens by aryl groups via cross-linking, and (iii) an increase in the aromatic cluster size, in addition to the well-known changes of the elimination of aliphatics and aromatic C-0 groups and an increase in aromaticity. For the first time, the growth of aromatic cluster sizes with increasing maturity was quantitatively estimated. Another novel finding is that coal kerogen (kerogen ¹22) directly in contact with the large dike retained considerable aliphatic components. This kerogen could have

been entrapped and would have failed to diffuse out rapidly enough due to intense and rapid heating, rendering this kerogen partially fluidized. Thermal maturation of kerogens due to magmatic intrusions may be different from that of long-term geologic heating. Type III coal kerogens used in the present study show documentation that the increase of aromaticity with increasing R0, is due to the removal of aliphatics accompanied by the increase in aromatic cluster sizes. In contrast, our previous NMR study on a series of Type II kerogens (R0, from 0.29% to to 1.27 %), that have experienced long-term heating, indicate that the increase of aromaticity with increasing R, was mainly related to the shortening of aliphatic chains attached to the aromatic cores, without significant growth of fused aromatic rings.

description: We demonstrate that the Hagedorn-like growth of the number of observed meson states can be used to constrain the degrees of freedom of the underlying effective QCD string. We find that the temperature relevant for such string theories is not given by the usual Hagedorn value $T_H\approx 160$ MeV, but is considerably higher. This resolves an apparent conflict with the results from a static quark-potential analysis, and suggests that conformal invariance and modular invariance are indeed reflected in the hadronic spectrum. We also find that the $D_\perp=2$ scalar string is in excellent agreement with data.

Using AstroImageJ, a software package for image processing, our team reduced, platesolved and performed aperture photometry on images of targets. Apertures were chosen through accounting for seeing, nearby companions, and target brightness. Comparison stars were then reviewed, and target light curves were detrended using various observation parameters. AstroImageJ was used to run a NEB star check, and transits of the target were modeled through ExoFASTv2. Findings from this data analysis have contributed to multiple TOI detections and continue to expand the validation of candidates from the TESS mission.

description: Density functional theory (DFT) calculations using sixteen different approaches, fourteen of which were designed to include dispersion interactions [DFT + D and van der Waals (vdW)-DF methods], were performed for a set of sixteen framework compounds with either SiO2 or AlPO4 composition. The compounds include four dense structures (α-quartz, α-cristobalite, and their AlPO4 analogues), eight all-silica zeolites, and four aluminophosphate zeotypes (AlPOs). We analyzed the performance in reproducing the equilibrium structure for all systems, and computed bulk moduli and relative stabilities were compared to experiments for those compounds where experimental data are available. We found that the results obtained with functionals that take into account dispersive interactions are closer to experiments than those obtained with a bare generalized gradient functional. However, the variation among individual methods is considerable, and functionals that perform well for one quantity may give rather large deviations for another. Taking together the whole body of results, it appears that the Perdew-Burke-Ernzerhof functional including a many-body dispersion correction and the rev-vdW-DF2 methods present the best performance for the description of SiO2 and AlPO4 materials.

description: Rightly or wrongly government plays an important role in the investment and operating decisions of transport firms. The Interstate Commerce Commission oversees a complicated structure of rates and a point-to-point system of operating licenses. For inland waterway transport, additional complications stem from the fact that the construction and maintenance of navigable waterways are controlled by Congress through the Army Corps of Engineers. It is necessary for Congress, the ICC, and the Army Corps of Engineers to cooperate and to pursue the national interest rather than the interest of any particular industry or company. These agencies therefore require knowledge of the underlying cost and demand functions. This paper is designed to provide some information on waterway cost functions.

title: Being Subjunctively Liminal: Performing Soliloquy in Contemporary Kunju Theatre
Creators: name: Meng, Ke
Publisher: name: School of Oriental and African Studies, University of London
Year: 2023

description: In this thesis, I construct a theatrical concept of “being subjunctively liminal”, which is derived both from solid cases of contemporary kunju 崑劇(kun drama) performances and from an interdisciplinary investigation of performance studies and modern philosophies. I argue that when the performer is left bare on stage, speaking/singing soliloquies, the moments of direct address elicit a state of being subjunctively liminal that denotes an intersubjective relationship between the performer and the audience, which will alter the ways of thinking about theatre as a method to reflect upon the eternally sophisticated issue between self and society. This thesis also theorises the convention of direct address in kunju. Using the concept as a new way of interpretation, contemporary kunju performances are rejuvenated as a useful site to re-examine some widely discussed issues in kunju studies. For dramatic characters, subjunctive liminality is a problematic state caused by authoritarian Confucian ideology, but this state also exposes their predicaments to the audience through direct address. Their soliloquies showcase their choices in a metaphysical sense: while for some dramatic characters, the subjunctive means to be again reassured and secured by the very same ideology, for others, the subjunctive means to imagine beyond current system and to push the boundary. “Being subjunctively liminal” works as a platform for each living individual to find their own contemporary relevance and resonance through their experiences of watching kunju.
Corruption from a Cross-Cultural Perspective

description: This paper views corruption as activity that tends to undermine a cultural system. Because cultures operate in very different ways, different activities are corrupting in different parts of the world. The paper analyzes real-life situations in Japan, Taiwan, India, China, North America, sub-Saharan Africa, the Middle East, and Korea to distinguish actions that structurally undermine a cultural system from those that are merely inefficient or are actually supportive. Activities such as nepotism or cronyism that are corrupting in the rule-based cultures of the West may be functional in relationship-based cultures. Behavior that is normal in the West, such as bringing lawsuits or adhering strictly to a contract, may be corrupting elsewhere. Practices such as bribery that are often corrupting across cultures are nonetheless corrupting for very different reasons. This perspective provides culturally-sensitive guidelines not only for avoiding corruption but for understanding the mechanisms that make a culture work.
Ultra-High Energy Cosmic Ray production in the polar cap regions of black hole magnetospheres

description: We develop a model of ultra-high energy cosmic ray (UHECR) production via acceleration in a rotation-induced electric field in vacuum gaps in the magnetospheres of supermassive black holes (BH). We show that if the poloidal magnetic field near the BH horizon is misaligned with the BH rotation axis, charged particles, which initially spiral into the BH hole along the equatorial plane, penetrate into the regions above the BH "polar caps" and are ejected with high energies to infinity. We show that in such a model acceleration of protons near a BH of typical mass 3e8 solar masses is possible only if the magnetic field is almost aligned with the BH rotation axis. We find that the power of anisotropic electromagnetic emission from an UHECR source near a supermassive BH should be at least 10-100 times larger then UHECR power of the source. This implies that if the number of UHECR sources within the 100 Mpc sphere is ~100, the power of electromagnetic emission which accompanies proton acceleration in each source, $10^{42-43}$ erg/s, is comparable to the typical luminosities of active galactic nuclei (AGN) in the local Universe. We also explore the acceleration of heavy nuclei, for which the constraints on the electromagnetic luminosity and on the alignment of magnetic field in the gap are relaxed.

description: When explaining others’ behaviors, achievements, and failures, it is common for people to attribute too much influence to the individual’s disposition and too little influence to the structural and situational influences impinging on the actor. Although performance is a joint function of ability and situational facilitation or impediments, dispositional inference ascribes too much to individual ability. We hypothesize that this tendency leads university admissions decisions to favor students coming from institutions with lenient grading because they will have their high performance mistaken for evidence of high ability. In four studies using both laboratory experiments and actual admissions decisions, we show that those who display high performance simply due to lenient grading or to an easy task are favored in selection. These results have implications for research on attribution, because they provide a more stringent test of the correspondence bias, and allow for a more precise measure of its size. Implications for admissions and personnel selection decisions are also discussed.
Strong coupling expansion of Baxter equation in N=4 SYM

description: The anomalous dimensions of single-trace local Wilson operators with covariant derivatives in maximally supersymmetric gauge theory are believed to be generated from a deformed noncompact sl(2) Baxter equation. We perform a systematic expansion of this equation at strong coupling in the single-logarithmic limit of large conformal spin to overcome the limitation of the asymptotic nature of the equation. The analysis is reduced to Riemann-Hilbert problems for corresponding resolvents of Bethe roots in each order of the quasiclassical expansion. We explicitly construct the resolvents in the lowest two orders in strong coupling and find all local conserved charges of the underlying long-range spin chain.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.
