description: In this paper we investigate the property (HLUR), a generalisation of (LUR) property of a Banach space. A Banach space having the property (HLUR) is called an HLUR space. We characterise (HLUR) property with the help of known geometric properties and study various properties of HLUR spaces. We show that for any finite dimensional Banach space, the property (HLUR) coincides with anti-Daugavet property of the space. We also show some applications of HLUR spaces in connection with farthest points of sets.

description: We study the mechanism of dynamical nuclear spin polarization by hyperfine interaction in spin-blocked double quantum dot system. We calculate the hyperfine transition rates and solve the master equations for the nuclear spins. Specifically, we incorporate the effects of the nuclear quadrupole coupling due to the doping-induced local lattice distortion and strain. Our results show that nuclear quadrupole coupling induced by the 5% indium substitution can be used to explain the recent experimental observation of missing arsenic NMR signal in the spin-blocked double dots.

description: In this work, long-chain hexadecyl siloxane groups were introduced into hydroxylated multi-walled carbon nanotubes (MWCNTs-OH) to obtain modified carbon nanotubes (CNTs) with super-hydrophobic characteristics. A novel super-hydrophobic/super-oleophilic polyurethane sponge (SH-MWCNTs@PU sponges) was achieved by performing further surface-modification with the super-hydrophobic CNTs via the immersion-coating process. The results showed that SH-MWCNTs@PU sponges exhibited excellent super-hydrophobic properties, with a water contact angle of 157.4 ± 1.1°, and water droplets roll-off angle of only 6.7°. In addition, its mechanical strength was greatly improved by the introduction of CNTs. Significantly, it exhibits excellent adsorption capability for different oils and organic solvents. The initial oil adsorption capacity is still maintained with a contact angle of 152.2° after 10 oil adsorption cycles, demonstrating good reusability of the SH-MWCNTs@PU sponges. The low-cost (the used MWCNTs-OH are industrial-grade), durable, and super-hydrophobic sponge is a promising material for oil–water separation with high efficiency and selectivity.

description: The successful detection of continuous gravitational waves from spinning neutron stars (NSs) will shape our understanding of the physical properties of dense matter under extreme conditions. Binary population synthesis simulations show that forthcoming space-borne gravitational wave detectors may be capable of detecting some tight Galactic double NSs with 10-min orbital periods. Successfully searching for continuous waves from the individual NS in such a close binary demands extremely precise waveform templates considering the interaction between the NS and its companion. Unlike the isolated formation channel, double NS systems from the dynamical formation channel have moderate to high orbital eccentricities. To accommodate these systems, we generalize the analytical waveforms from triaxial nonaligned NSs under spin-orbit coupling derived by Feng \textit{et al.} [\href{https://journals.aps.org/prd/abstract/10.1103/PhysRevD.108.063035}{Phys. Rev. D 108, 063035 (2023)}] to incorporate the effects of the orbital eccentricity. Our findings suggest that for binaries formed through isolated binary evolution, the impact of eccentricity on the continuous waves of their NSs can be neglected. In contrast, for those formed through dynamical processes, it is necessary to consider eccentricity, as high-eccentricity orbits can result in a fitting factor of $\lesssim 0.97$ (0.9) within approximately 0.5 (1) to 2 (5) yr of a coherent search (at wave frequencies of 100 and 200 Hz). Once the continuous waves from spinning NSs in tight binaries are detected, the relative measurement accuracy of eccentricity can reach $Δe / e \sim O(10^{-7})$ for a signal-to-noise ratio of $O(100)$ based on the Fisher information matrix, bearing significant implications for understanding the formation mechanisms of double NS systems.

description: This paper explores the link between learner autonomy and critical thinking and aims to propose a practical approach to promote both skills in English classes at Japanese universities. Based upon the relevant literature review and examination of two survey questionnaires, the conclusion indicates that autonomous learning skills play an essential role in developing critical thinking skills among university students. In addition, more emphasis needs to be placed on the role of the teacher as a facilitator in order to enhance the quality of English education at Japanese universities.

description: The purpose of the study is to examine the pedagogical usability of interactive e-learning materials for foreign language practice. It is based upon two studies of the expected between-group and within-group differences among participants in the educational process. The sample consists of two groups – lecturers and students, a total of 100 participants, each evaluating four materials specifically prepared for this study. Two consecutive repeated measures ANOVA were conducted in which the gender/age, the position of the participants in the educational process, and usability dimensions were the independent variables. Results indicated that all independent variables and their interactions have a significant effects on the evaluations of the pedagogical usability. Women tend to assign higher values than men. Аge groups generally differ in their evaluations, although there is a tendency to give similar ratings for the individual dimensions of pedagogical usability. The 31-40 years age group evaluates the materials higher while the lowest evaluations are given by the groups of 21-30 and 50+ year old participants. Students tend to rate the pedagogical usability systemically higher than the lecturers. Usability dimensions also have a significant effect on evaluations. The most prominent feature of the materials, by a great margin, is their Applicability. The findings corroborate previous research which show age and gender differences in web usability do exist. We conclude that these differences exist as much in pedagogical usability as in technical usability. Further investigations are suggested to explore more deeply the differences in the perceived pedagogical value of e-learning materials as this has implications for instructional designers, teachers and learners alike.

description: The paper examines poverty in urban Ethiopia using household survey data for 1994 and 2000. Consumption poverty is found to be high, with an overall head count of 47 per cent, in 1994, and 40 per cent, in 2000. As monetary measures may not appropriately capture welfare in non-monetary dimensions of life, non-monetary indicators, such as, subjective welfare status, nutritional status of children and housing characteristics are also examined. The findings indicate that there is a significant association between consumption poverty and subjective welfare status, but a weak agreement in ranking of households. Non poor households, in terms of consumption, are found to enjoy better housing amenities. However, the association between consumption poverty and child nutritional status is not strong. Poverty dynamics is also analysed using transition matrices and multivariate regression techniques. It was found that over 58 per cent of panel households had experienced poverty at least once during the period. Of these, over half had been chronically poor. The poverty transition was also quite significant with over a quarter of households experiencing a change in their poverty status. The results also showed that households with higher dependency ratio and whose heads are self employed, casual workers, pensioners and unemployed have a lower probability of exiting poverty. Those that are educated and belong to major ethnic groups have a higher probability of exit. Similar factors are significant in affecting the probability of entry.

description: In this paper, we present a machine learning approach for estimating the number of incident wavefronts in a direction of arrival scenario. In contrast to previous works, a multilayer neural network with a cross-entropy objective is trained. Furthermore, we investigate an online training procedure that allows an adaption of the neural network to imperfections of an antenna array without explicitly calibrating the array manifold. We show via simulations that the proposed method outperforms classical model order selection schemes based on information criteria in terms of accuracy, especially for a small number of snapshots and at low signal-to-noise-ratios. Also, the online training procedure enables the neural network to adapt with only a few online training samples, if initialized by offline training on artificial data.

description: The use of protected areas as a fishery management tool has been suggested as a hedge against management failures and variation in harvests. A stochastic bioeconomic model of a two-species fishery will be used to test the performance of protected areas as a management tool in a fishery with heterogenous environments. Protected areas are analysed under density-dependent and sink-source dispersal relationships between environments within the fishery. Differing levels of management control over fishery resource extraction are analysed. The model is applied to Manning Bioregion in NSW. The focus of the study is placed on the biological and institutional characteristics that yield benefits to the fishery.

description: Marine protected areas have been advocated as a useful tool in fisheries management. However, as protected areas they are a ‘blunt’ tool to manage fishery operations; in the sense that they do not alter the incentives of individual fishers, the outcomes from protected area creation are likely to be dependent on other management mechanisms which alter incentives. Implementing protected area management of fisheries has also been viewed as beneficial in the sense that they provide a low cost management tool. In this paper, the optimal fishery management structure, in light of transaction costs, and which integrates protected areas and effort controls as a mechanism used to control the extraction of fishery resources, is explored. The policy implications of the results are also discussed.

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.

Close-in giant-planet formation via in-situ gas accretion and their natal disk properties

description: The origin of close-in Jovian planets is still elusive. We examine the in-situ gas accretion scenario as a formation mechanism of these planets. We reconstruct natal disk properties from the occurrence rate distribution of close-in giant planets, under the assumption that the occurrence rate may reflect the gas accretion efficiency onto cores of these planets. We find that the resulting gas surface density profile becomes an increasing function of the distance from the central star with some structure at $r \simeq 0.1$ au. This profile is quite different from the standard minimum-mass solar nebula model, while our profile leads to better reproduction of the population of observed close-in super-Earths based on previous studies. We compute the resulting magnetic field profiles and find that our profiles can be fitted by stellar dipole fields ($\propto r^{-3}$) in the vicinity of the central star and large-scale fields ($\propto r^{-2}$) at the inner disk regions, either if the isothermal assumption breaks down or if nonideal MHD effects become important. For both cases, the transition between these two profiles occurs at $r \simeq 0.1$ au, which corresponds to the period valley of giant exoplanets. Our work provides an opportunity to test the in-situ gas accretion scenario against disk quantities, which may constrain the gas distribution of the minimum-mass {\it extra}solar nebula.

description: In this paper we discuss the definition, the construction and the implementation of \textit{generalised antenna functions} for final-state radiation up to Next-to-Next-to-Leading Order (NNLO) in QCD. Generalised antenna functions encapsulate the singular behaviour of unresolved emissions when these occur within multiple hard radiators and not just two of them, as for traditional antenna functions. The construction of such objects is possible thanks to the recently proposed algorithm for building \textit{idealised antenna functions} from a target set of infrared limits. Generalised antenna functions bring major simplifications in the assemblage of subtraction terms in the context of the antenna scheme at NNLO and beyond, as well as a substantial computational speedup of higher-order calculations. We discuss in detail the improvements on the formal and practical side for the computation of the NNLO correction to three-jet production at electron-positron colliders, providing a thorough numerical validation of the newly proposed scheme. For this calculation one can expect almost an order of magnitude speedup with respect to the original implementation.

description: The Great Gerbil, Rhombomys opimus, is widely distributed in degraded and fragmented desert and semi-desert habitats of the Iranian Plateau. Recent habitat fragmentation from overgrazing by livestock and a government-sponsored rodent control programme threaten to isolate populations and increase their susceptibility to inbreeding and loss of genetic diversity. We examined genetic data of the Great Gerbil in a region where they are data deficient to understand how distance, geography, and anthropogenic factors influence genetic population structure and genetic diversity at the landscape level. We extracted genomic DNA from 109 blood samples collected from nine populations across the Iran’s landscape and amplified four microsatellite loci to examine levels of genetic diversity and genetic population structure. Our analysis revealed two genetic clusters (K=2) that corresponded to R. opimus sodalis in the north slope of the Alborz Mountains (AM) and Kopet-Dagh Mountains (KDM) and R. opimus sargadensis in the south slope of AM and KDM. However, the observed genetic population structure could not be fully explained by north and south slopes of AM and KDM. Genetic variation was low to relatively high (FST ranged from 0.015 to 0.167) and was significant among some populations. We did not find a correlation between genetic distance and geographic distance, which indicates that the geographical distance was not an influential factor in genetic differentiation of the species in Iran. Genetic diversity within the populations studied appears to be the result of a complex mixture of limited local dispersal, social structure favoring female philopatry, and common ancestral frequencies.

description: We report on the first near-simultaneous X-ray and optical observations of RX J0806.3+1527. The source is believed to be a 321s orbital period ultra-compact binary system hosting an X-ray emitting white dwarf. Data were obtained with Chandra and the ESO Very Large Telescope (VLT) in November 2001. We found an optical/X-ray phase-shift in the periodic modulation of about 0.5, strongly favoring the existance of two distinct emission regions in the two bands (for the pulsed fluxes). The Chandra data allow us to study, for the first time, the spectral continuum of RX J0806.3+1527 in soft X-rays. This was well fitted by a blackbody spectrum with kT about 65eV and hydrogen column density of N_H about 5 x 10^20 cm^-2. The average (unabsorbed) source 0.1-2.5 keV luminosity during the modulation-on is L_X about 5 x 10^32 erg s^-1 (assuming a distance of 500pc). Such a value is lower than the luminosity expected if stable mass transfer between two white dwarfs were driven by gravitational radiation. Evidence for absorption-like features are present in the phase-averaged spectrum at about 0.53, 0.64, and 1.26 keV, which may be attributed to heavy elements (C and N). We compare and discuss these findings with other binary systems hosting an accreting white dwarf.

description: The one-electron spectral function of the Holstein-Hubbard bipolaron in one dimension is studied using cluster perturbation theory together with the Lanczos method. In contrast to other approaches, this allows one to calculate the spectrum at continuous wave vectors and thereby to study, for the first time, the dispersion and the spectral weight of quasiparticle features. The formation of polarons and bipolarons, and their manifestation in the spectral properties of the system, is studied for the cases of intermediate and large phonon frequencies, with and without Coulomb interaction. A good agreement is found with the most accurate calculations of the bipolaron dispersion available, over a large range of the electron-phonon coupling strength. Additionally, pronounced deviations of the bipolaron dispersion from a simple tight-binding band are found, which can be attributed to next-nearest-neighbor hopping processes.

description: This study aimed to compare the difference in maximum speech discrimination score (SDSmax) of the worse-hearing ear in asymmetric hearing loss (ASHL) patients with that in symmetric hearing loss (SHL) patients. We retrospectively reviewed medical records of patients with suspected hearing loss (HL) who underwent audiometric examinations. Patients were divided into two groups according to the difference in air conduction (AC) threshold between the right and left ears: the SHL group and the ASHL group. Of the 102 patients (204 ears), 74 (148 ears) had SHL, and 28 had ASHL. The worse-hearing ear of ASHL patients exhibited a statistically significantly higher AC threshold and lower SDSmax, compared with ears of SHL patients and better-hearing ears of ASHL patients, and SDSmax exhibited a statistically significant negative correlation with AC threshold. The SDSmax was statistically significantly lower in the worse-hearing ear of the ASHL group than in moderate to severe HL ears of the SHL group, even though these groups had comparable AC thresholds. ASHL patients’ worse-hearing ear exhibited a lower SDSmax than SHL patients’ ears, despite a comparable AC threshold. Management of hearing impairment in ASHL patients should receive more attention.

description: Recently, discussion about the appropriate estimation of gravity trade models has started in agriculture. Here, we are going to review recent developments in the literature. It appears that fixed effects Poisson Pseudo Maximum Likelihood is not only the only consistent estimator [Santos Silva and Tenreyro, 2006] but also it already allows for a structural fit [Fally, 2012]. Fixed effects in conjunction with the adding-up property of Poisson Pseudo Maximum Likelihood - which has been so far neglected - can be harnessed to directly deduce multilateral resistance indexes (i.e. general equilibrium effects) from reduced-form estimation. This innovation made by Fally will ease comparative statics and incidence analysis, making Poisson Pseudo Maximum Likelihood even more preferable in practice.

description: We study X-ray and variability and distance of GX 339-4. We derive d>7 kpc, based on recent determination of the binary parameters. We study data from the Ginga/ASM, the CGRO/BATSE, and the RXTE/ASM, PCA and HEXTE. From 1987 to 2004, GX 339-4 underwent 15 outbursts and went through all known states of black-hole binaries. We also present the PCA data from the initial stage of the 2004 outburst. We then study colour-colour and colour-flux correlations. In the hard state, there is a strong anticorrelation between the 1.5-5 and 3-12 keV spectral slopes, which we explain by thermal Comptonization of disc photons. There is also a softening of the spectrum above 3 keV with the increasing flux that becomes stronger with increasing energy up to 200 keV. This indicates an anticorrelation between the electron temperature and luminosity, explained by hot accretion models. In addition, we see a variable broad-band slope with a pivot at 200 keV. We confirm the presence of pronounced hysteresis, with the hard-to-soft state transitions occurring at much higher (and variable) luminosities than the soft-to-hard transitions. We fit the ASM data with a model consisting of an outer accretion disc and a hot inner flow. State transitions are associated then with variations in the disc truncation radius, which we fit as 6GM/c^2 in the soft state and several times that in the hard state. The disappearence of the inner disc takes place at a lower accretion rate than its initial appearance due to the dependence of the transitions on the source history. We provide further evidence against the X-ray emission in the hard state being nonthermal synchrotron, and explain the observed radio-X-ray correlation by the jet power being correlated with the accretion power.

description: We numerically investigate the stress distribution in pastes after horizontal rotation by using an elasto-plastic model. Residual stress remains as a memory of rotation. The stress in the circumferential direction increases after the rotation, whereas that in the radial direction decreases. The residual stress is analytically related to the plastic deformation induced by the rotation. Based on the time evolution of plastic deformation, we theoretically describe the mechanism of the changes in the stress distribution.

description: To determine if exposure to organic solvents and noise is associated with audiometric results among workers from a printing press in Mexico City. Cross-sectional study. One hundred and seventy-six male workers at a printing press in Mexico City exposed to noise and organic solvents, including xylene, and 103 non-exposed male workers as reference group. Hearing thresholds were assessed with pure-tone audiometry. Poorer hearing thresholds were observed among printing workers than non-exposed controls, particularly among groups with over 5 years of exposure. Hearing thresholds differences were observed in the frequencies above 500 Hz, especially in 4000 Hz in all exposure groups compared to the reference. Adjusted models for age and previous exposure to noise and organic solvents showed worse hearing thresholds as years of seniority increased –β coefficients (95% CI): ≤5 years: 3.06 dB (0.01, 6.10); >5–10 years: 4.51 dB (1.13, 7.89); >10 years: 4.58 dB (1.20, 7.96). Further analyses showed no interaction between noise and organic solvents on hearing thresholds, considering both current and previous occupational exposures. Exposure to noise levels that were below recommended exposure limits and organic solvents were associated with poorer hearing thresholds than those observed among non-exposed study participants. This suggests that workers exposed to solvents should be included in hearing conservation programmes, even when noise exposures are below 85 dB. If only noise levels were taken into consideration in the risk assessment of this worker population, the risk of hearing effects could have been overlooked.

description: Sulfonation is an important high affinity elimination pathway for phenolic compounds.In this study sulfonation of 7-hydroxycoumarin and 13 its derivatives were evaluated in liver cytosols of human and six animal species. 7-hydroxycoumarin and its derivatives are strongly fluorescent, and their sulfate conjugates are nonfluorescent at excitation 405 nm and emission 460 nm. A convenient fluorescence based kinetic assay of sulfonation was established.The sulfonation rate of most of the 7-hydroxycoumarin derivatives was low in liver cytosol of human and pig, whereas it was high with most compounds in dog and intermediate in rat, mouse, rabbit, and sheep. Sulfonation of the 7-hydroxycoumarin derivatives followed Michaelis-Menten kinetics with Km values of 0.1–12 µM, Vmax of 0.005–1.7 µmol/(min * g protein) and intrinsic clearance (Vmax/Km) of 0.004–1.9 L/(min * g cytosolic protein).Fluorescence based measurement of sulfonation of 7-hydroxycoumarin derivatives provides a sensitive and convenient high-throughput assay to determine sulfonation rate in different species and tissues and can be applied to evaluate sulfonation kinetics and inhibition.

Operation Video. The Use of Images as Visual Agents in Struggles over Representation

description: This paper focuses on the notions of the gaze and proximity in visual culture, and their relation to the sense of distancing on the one hand and tactile sensations on the other. Jean Baudrillard, a representative agent of postmodernism, argues in his video studies that the circulation of electronic images causes external reality as a subject to vanish. For Baudrillard, the screen aesthetics of close-ups have an inherent obscenity, which he compares with the effect of gender change as a disturbingly unstable notion. Based on the analysis of various video works, among others by Lisa Steele, Lili Dujourie, Lynn Hershman, Adrian Piper and Eleanor Antin, this paper argues that some of these works, above all those from the 1970s, run counter to Baudrillard’s basic claim. Rather than foregrounding a dissolving or vanishing subject, these works feature a subject that discovers itself – albeit differently. Discussing selected examples of early video discourse, and its different mode of seeing, the paper delineates some of the shifts that have occurred in the discourse on subjectivity. This essay is based on my doctoral dissertation (Operation Video. Eine Technik des Nahsehens und ihr spezifisches Subjekt: die Videokünstlerin der 1970er Jahre. Bielefeld, Transcript, 2008). The present version was first delivered at the ASCA Workshop Engaging Objects at the University of Amsterdam in March 2008, and has not been previously published in English.

description: We provide approximate solutions for the mobility edge (ME) that demarcates localized and extended states within a specific class of one-dimensional non-Hermitian (NH) quasicrystals. These NH quasicrystals exhibit a combination of nonreciprocal hopping terms and complex quasiperiodic on-site potentials. Our analytical approach is substantiated by rigorous numerical calculations, demonstrating significant accuracy. Furthermore, our ansatz closely agrees with the established limiting cases of the NH Aubry-Andr{é}-Harper (AAH) and Ganeshan-Pixley-Das Sarma (GPD) models, which have exact results, thereby enhancing its credibility. Additionally, we have examined their dynamic properties and discovered distinct behaviors in different regimes. Our research provides a practical methodology for estimating the position of MEs in a category of NH quasicrystals that break duality.

description: The prompt muon contribution to the deep-sea atmospheric muon flux can serve as a tool for probing into the small-x feature of the gluon density inside of a nucleon, if the muon energy threshold could be lifted to 100 TeV. The prompt muon flux underwater is calculated taking into consideration predictions of recent charm production models in which the small-x behaviour of the gluon distribution is probed. We discuss the possibility of distinguishing the PQCD models of the charm production differing in the small-x exponent of the gluon distribution, in measurements of the muon flux at energies 10-100 TeV with neutrino telescopes.

description: In forecasting multiple time series, accounting for the individual features of each sequence can be challenging. To address this, modern deep learning methods for time series analysis combine a shared (global) model with local layers, specific to each time series, often implemented as learnable embeddings. Ideally, these local embeddings should encode meaningful representations of the unique dynamics of each sequence. However, when these are learned end-to-end as parameters of a forecasting model, they may end up acting as mere sequence identifiers. Shared processing blocks may then become reliant on such identifiers, limiting their transferability to new contexts. In this paper, we address this issue by investigating methods to regularize the learning of local learnable embeddings for time series processing. Specifically, we perform the first extensive empirical study on the subject and show how such regularizations consistently improve performance in widely adopted architectures. Furthermore, we show that methods attempting to prevent the co-adaptation of local and global parameters by means of embeddings perturbation are particularly effective in this context. In this regard, we include in the comparison several perturbation-based regularization methods, going as far as periodically resetting the embeddings during training. The obtained results provide an important contribution to understanding the interplay between learnable local parameters and shared processing layers: a key challenge in modern time series processing models and a step toward developing effective foundation models for time series.

The Mott transition as a topological phase transition

description: We show that the Mott metal-insulator transition in the standard one-band Hubbard model can be understood as a topological phase transition. Our approach is inspired by the observation that the mid-gap pole in the self-energy of a Mott insulator resembles the zero-energy spectral pole of the localized surface state in a topological insulator. We use NRG-DMFT to solve the infinite-dimensional Hubbard model, and represent the resulting local self-energy in terms of the boundary Green's function of an auxiliary tight-binding chain without interactions. The auxiliary system is of generalized SSH model type; the Mott transition corresponds to a dissociation of domain walls.
