Constraints on the Generalized Uncertainty Principle from black-hole thermodynamics

In this paper, we calculate the modification to the thermodynamics of a Schwarzschild black hole in higher dimensions due to the Generalized Uncertainty Principle (GUP). We use the fact that the leading-order corrections to the entropy of a black hole has to be logarithmic in nature to restrict the form of the GUP. We observe that in six dimensions, the usual GUP produces the correct form for the leading-order corrections to the entropy of a black hole. However, in five and seven dimensions a linear GUP, which is obtained by a combination of DSR with the usual GUP, is needed to produce the correct form of the corrections to the entropy of a black hole. Finally, we demonstrate that in five dimensions, a new form of GUP containing quadratic and cubic powers of the momentum also produces the correct form for the leading-order corrections to the entropy of a black hole.
Single Document Summarization Using BertSum and Pointer Generator Network

: The rapid development of textual data requires an automated text summarization system to obtain shortened versions of documents quickly and accurately. This paper investigates the performances of BertSum and Pointer Generator Network (PGN) on the IndoSum corpus containing Indonesian news articles. We compare these methods to NeuralSum, which is claimed to outperform other methods when working with the IndoSum dataset. In our experiment, BertSum with Indonesian's pre-trained model outperformed NeuralSum in extractive summarization. NeuralSum, on the other hand, tends to select the leading sentences as a summary and occasionally produces a blank summary. Meanwhile, PGN effectively prevents word repetition by using a coverage mechanism, although the summary results are sometimes out of context.
Unification and new extensions of the no-pumping theorems of stochastic pumps

From molecular machines to quantum dots, a wide range of mesoscopic systems can be modeled by periodically driven Markov processes, or stochastic pumps. Currents in the stochastic pumps are delimited by an exact no-go condition called the no-pumping theorem (NPT). This letter presents a unified treatment of all the adaptations of NPT known so far, and further extends it to systems with many species of interacting particles.
Reduced glomerular filtration rate is associated with ascending aortic dilatation in South African chronic kidney disease patients

Background: Ascending aortic dilatation (AAD) is an adverse prognostic cardiovascular marker in the general population. There are few data reporting its presence or clinical significance in chronic kidney disease (CKD) patients. The aim of this study was to evaluate ascending aorta dimensions and their correlates in a population of South African CKD patients.Methods: A total of 124 CKD patients and 40 healthy controls were enrolled. Cardiac dimensions, systolic and diastolic function indices, and aortic root diameters were assessed by transthoracic echocardiography. The ascending aorta was measured at four levels (aortic annulus, sinuses of Valsalva, sino-tubular junction, and ascending aorta) and was normalised for body surface area. The prevalence of AAD was assessed in CKD patients compared with the control group.Results: In CKD patients, the ascending aorta dimension was significantly larger than in controls at all four sites of the aorta that were measured. The prevalence of AAD was 6.5% at the annulus, 12.9% at the sinuses, 15.3% at the sino-tubular junction, and 8.9% at the ascending aorta. Overall, 29 patients (23%) had AAD. On multivariate analyses, eGFR was independently associated with AAD (odds ratio 0.980; 95% confidence interval 0.965–0.996; P = 0.014). Conclusion: AAD is a common cardiovascular phenotype in South African CKD patients. Low eGFR was independently associated with AAD, suggesting a direct link between CKD and the development of AAD in South African CKD patients. Keywords: chronic kidney disease, cardiovascular disease, ascending aortic dilatation
Theory of neutral and charged excitons in monolayer transition metal dichalcogenides

We present a microscopic theory of neutral excitons and charged excitons (trions) in monolayers of transition metal dichalcogenides, including molybdenum disulfide. Our theory is based on an effective mass model of excitons and trions, parametrized by ab initio calculations and incorporating a proper treatment of screening in two dimensions. The calculated exciton binding energies are in good agreement with high-level many-body computations based on the Bethe-Salpeter equation. Furthermore, our calculations for the more complex trion species compare very favorably with recent experimental measurements, and provide atomistic insight into the microscopic features which determine the trion binding energy.

Influence of Shallow Groundwater Evapotranspiration on Recharge Estimation Using the Water Table Fluctuation Method

Groundwater recharge moves downward from the land surface and reaches the groundwater to replenish aquifers. Despite its importance, methods to directly measure recharge remain cost and time‐intensive. Recharge is usually estimated using indirect methods, such as the widely used water‐table fluctuation (WTF) method, which is based on the premise that rises in groundwater levels are due to recharge. In the WTF method, recharge is calculated as the difference between the observed groundwater hydrograph and the hydrograph obtained in the absence of water input. The hydrograph in the absence of rise‐producing input is estimated based on a characteristic master recession curve (MRC), which describes an average behavior for a declining water‐table. Previous studies derive MRC using recession data from all seasons. We hypothesize that for sites where groundwater table is shallow, using recession data from periods with high groundwater‐influenced evapotranspiration (ET) rates versus all periods will yield significantly different MRC, and consequently different estimates of recharge. We test this hypothesis and show that groundwater recession rates are significantly greater in warm months when the groundwater‐influenced ET rates are higher. Since obtaining seasonal recession rates is challenging for locations with a limited amount of data and is prohibitive if it is to be obtained for any given season of a particular year, we propose two novel parsimonious methods to obtain recession time constants for distinct seasons. The proposed methods show the potential to significantly improve the estimates of seasonal recession time constants and provide a better understanding of seasonal variations in recharge estimates.
Unveiling the radio counterparts of two binary AGN candidates: J1108+0659 and J1131-0204

The sources SDSS\,J113126.08-020459.2 and SDSS\,J110851.04+065901.4 are two double-peaked [O III] emitting AGN, identified as candidate binary AGNs by optical and near infrared (NIR) observations. We observed the two sources with high resolution Very Long Baseline Interferometry (VLBI) using the European VLBI Network at 5\,GHz, reduced VLA observations at three frequencies available for one of the sources, and used archival HST observations. For the source SDSS\,J113126.08-020459.2, the VLBI observations detected only one single compact component associated with the eastern NIR nucleus. In SDSS\,J110851.04+065901.4, the VLBI observations did not detect any compact components, but the VLA observations allowed us to identify a possible compact core in the region of the north-western optical/NIR nucleus. In this source we find kpc-scale extended radio emission that is spatially coincident to the ultraviolet continuum and to the extended emission narrow line region. The UV continuum is significantly obscured since the amount of extended radio emission yields a star formation rate of about 110 \msunyr, which is an order of magnitude larger than implied by the observed ultraviolet emission. Our analysis confirms the presence of only one AGN in the two candidate binary AGNs.
On Supermembrane in D=4, multiple M0-brane in D=11 and Supersymmetric Higher Spin Theories

In this thesis we have obtained and studied the complete set of superfield equations of motion for the interacting system of four-dimensional supermembrane and dynamical scalar multiplet. This study provides the first example of superfield equations for interacting system involving matter superfields and extended supersymmetric object, as well as the first set of superfield equations of motion for a dynamical system which includes supermembrane. The action for a supermembrane in a N = 1 D = 4 chiral superfield background has been also presented for the first time. We have obtained the complete set of equations of motion in spacetime components for the interacting system of dynamical D = 4 N = 1 supergravity and supermembrane from the superfield equations. To this end we have developed the Wess - Zumino approach type to Grisaru - Siegel - Gates - Ovrut - Waldram special minimal supergravity characterized by a dynamically generated cosmological constant. We have also found the superfield equations in N-extended tensorial superspaces with N = 2,4 and 8, which describe the D = 4 supermultiplets of massless conformal higher spin theory with N-extended supersymmetry. On the other hand, we have obtained the equations of motion of the system of multiple M0-brane derived from the covariant, supersymmetric and kappa-symmetric action proposed for such a system . We have also studied the gauge symmetries of the action which allows us to find the final form of the bosonic equations of motion for the center of energy coordinate functions. We have also shown that all BPS states of the system are (1/2)BPS states and have the same properties as the BPS states of a single M0-brane.
THE ACOUSTIC CUTOFF FREQUENCY OF THE SUN AND THE SOLAR MAGNETIC ACTIVITY CYCLE

The acoustic cutoff frequency—the highest frequency for acoustic solar eigenmodes—is an important parameter of the solar atmosphere as it determines the upper boundary of the p-mode resonant cavities. At frequencies beyond this value, acoustic disturbances are no longer trapped but are traveling waves. Interference among them gives rise to higher-frequency peaks—the pseudomodes—in the solar acoustic spectrum. The pseudomodes are shifted slightly in frequency with respect to p-modes, making possible the use of pseudomodes to determine the acoustic cutoff frequency. Using data from the GOLF and VIRGO instruments on board the Solar and Heliospheric Observatory spacecraft, we calculate the acoustic cutoff frequency using the coherence function between both the velocity and intensity sets of data. By using data gathered by these instruments during the entire lifetime of the mission (1996 until the present), a variation in the acoustic cutoff frequency with the solar magnetic activity cycle is found.
Interactive Machine Learning on Edge Devices With User-in-the-Loop Sample Recommendation

Interactive machine learning (IML) aims to make machine learning an easy-to-use tool for novice users to solve personalized tasks. However, despite the recent popularity of edge AI, research into interactive machine learning on edge devices has not been conducted actively. Existing IML designs cannot be directly applied to small edge devices due to interface and computational resource limitations. In this paper, we propose a method for efficient model personalization on a small interactive object recognition camera device by combining sample recommendations with an IML workflow. The proposed method recommends training data candidates from unlabeled samples in addition to the usual annotation operations. Our method interactively trains a noise filter to handle a noisy sample pool obtained while using the device. The user can indicate whether the recommended sample corresponds to 1) the recommended class; 2) other classes; or 3) noise unrelated to the recognition task by providing ternary feedback. Our system is designed to gradually update both the target classifier and the noise filtering recommendation modules on the basis of feedback. We show that our feedback design achieves more efficient model training while improving system usability through a systematic evaluation and user study using a prototype device.
(In)visible powers: witnessing the ‘tourist-waters’ of Nämforsen

This artistic research reflection explores Sweden’s legally-mandated ‘tourist-release’ at the Ångermanälven River’s storied site of Nämforsen. Against World Wars and calls for energy independence of the mid 1940s, the iconic Ångermanälven River was industrialised from a free-flowing salmon river to eventually a series of 44 dams and hydropower plants. Later, a unique environmental court legal judgement resulted in ‘tourist-water’ at Nämforsen that gives the illusion of a free-flowing river during summer months. Existing for solely aesthetic purposes, tourist-water is an unexplored example of the (in)visible powers perpetuating myths associated with hydropower and place in Sweden. Through text and images, this piece reflects on witnessing this tourist-water phenomena through place-based documentary arts practice. The fieldwork is part of a doctoral project in artistic practice focusing on how photography can mediate complex issues in places of environmental change through the case of Nämforsen. Strategies such as framing, time-scaling and montage have emerged from this practice at the same time as ethical concerns related to representation are raised. This case is especially pertinent as hydropower in Sweden comes under increased scrutiny, simultaneously as it is marketed as a sustainable energy solution. The piece furthermore highlights the lasting implications of conservation efforts centred historically on aesthetic rather than ecologic values.

This work presents a fully integrated 140-GHz transmitter (TX) achieving a data rate of 160 Gb/s with ~1-pJ/b efficiency in the 22-nm Intel FinFET technology. The TX leverages a wideband radio frequency digital to analog converter (RF-DAC) architecture with embedded 4:1 multiplexer, and it is integrated with a sub-sampling quadrature phase-locked loop (PLL), frequency tripler, local oscillator (LO) buffers, wideband two-stage power amplifier (PA), and on-chip SRAM/pseudorandom binary sequence (PRBS) for high-speed data generation. The TX achieves 120/160-Gb/s 16 quadratic-amplitude modulation (QAM) with −19/−17-dB error vector magnitude (EVM) at an output power of +1.5/+0.8 dBm.
Psychologists’ perceptions of assessing and treating trauma-exposed clients

ABSTRACT Objective Psychologists are primary care professionals responsible for providing treatment to people exposed to trauma. However, there has been limited research exploring psychologists’ perceptions of their practice and trauma-informed care when treating people exposed to trauma. The current study aimed to investigate: 1) psychologists’ perceptions of assessing and treating trauma-exposed clients; and 2) psychologists’ perceptions of trauma-informed practice and their need for further training in this area. Method Surveys were completed by 99 psychologists, and the data were analysed using thematic analysis. Results Psychologists reported the importance of further trauma-related training and showed an inconsistent understanding of trauma-informed practice. Conclusions Changes in tertiary education for psychologists were recommended to assist future psychologists to develop competency and confidence in assessing and treating trauma-exposed clients. It was also recommended that psychologists with insufficient knowledge in this field to undertake further training in this area. Key Points What is already known about this topic: (1) Psychologists are primary care professionals responsible for diagnosing and treating clients exposed to trauma. (2) Working with trauma-exposed clients presents a burden for psychologists in terms of their mental health and wellbeing. (3) There is limited Australian and international research concerning the experiences and needs of psychologists when assessing and treating trauma-exposed clients. What this topic adds: (1) This study demonstrated Australian psychologists’ mixed knowledge and confidence when assessing and treating clients exposed to trauma. (2) Mixed understanding of trauma-informed care and ways to implement trauma-informed practice were also presented. (3) More professional development for some psychologists is recommended regarding assessing and treating trauma, and regarding trauma-informed practice.
Reconstruction of the Structure of Accretion Disks in Dwarf Novae from the Multi-Band Light Curves of Early Superhumps

We propose a new method to reconstruct the structure of accretion disks in dwarf novae using multi-band light curves of early superhumps. Our model assumes that early superhumps are caused by the rotation effect of non-axisymmetrically flaring disks. We have developed a Bayesian model for this reconstruction, in which a smoother disk-structure tends to have a higher prior probability. We analyzed simultaneous optical and near-infrared photometric data of early superhumps of the dwarf nova, V455 And using this technique. The reconstructed disk has two flaring parts in the outermost region of the disk. These parts are responsible for the primary and secondary maxima of the light curves. The height-to-radius ratio is h/r=0.20-0.25 in the outermost region. In addition to the outermost flaring structures, flaring arm-like patterns can be seen in an inner region of the reconstructed disk. The overall profile of the reconstructed disk is reminiscent of the disk structure that is deformed by the tidal effect. However, an inner arm-like pattern, which is responsible for the secondary minimum in the light curve, cannot be reproduced only by the tidal effect. It implies the presence of another mechanism that deforms the disk structure. Alternatively, the temperature distribution of the disk could be non-axisymmetric. We demonstrate that the disk structure with weaker arm-like patterns is optimal in the model including the irradiation effect. However, the strongly irradiated disk gives quite blue colors, which may conflict with the observation. Our results suggest that the amplitude of early superhumps depends mainly on the height of the outermost flaring regions of the disk. We predict that early superhumps can be detected with an amplitude of >0.02 mag in about 90% of WZ Sge stars.
Numerical Simulation of the Nonlinear Propagation of Ultrashort Pulses in Fiber Amplifiers Using Time-Frequency Representations

To predict the behavior of high power pulsed lasers, fine numerical simulations of nonlinear propagation of short chirped pulses in fiber amplifiers are needed. In particular, the gain used in the nonlinear Schrödinger equation (NLSE) should take into account the simultaneous dependence of the gain with frequency (i.e. gain dispersion) and time (i.e. gain saturation). We propose here a method using a time-frequency representation (TFR) of the pulse to compute the gain that can be used in the NLSE. Basic TFRs can be computed by estimating the group delay or the instantaneous frequency of the pulse but the low numerical complexity of these methods introduce some limitations in term of cases that can be properly simulated. We show that the more time-consuming computation of the reassigned spectrogram (RS) of the pulse allows to obtain a gain more suitable for general cases than can be encountered in high energy ultrafast lasers.
Superconductivity and Intercalation Statein the Lithium-Hexamethylenediamine-Intercalated Superconductor Li$_x$(C$_6$H$_{16}$N$_2$)$_y$Fe$_{2-z}$Se$_2$: Dependence on the Intercalation Temperature and Lithium Content

The superconductivity and intercalation statein the lithium-and hexamethylenediamine (HMDA)-intercalated superconductor Li$_x$(C$_6$H$_{16}$N$_2$)$_y$Fe$_{2-z}$Se$_2$ have been investigated from powder x-ray diffraction, thermogravimetric and magnetic susceptibility measurements, changing the intercalation temperature, $T_i$, and the Li content, $x$. Both Li and HMDA have been co-intercalated stably up to $x$ = 2 roughly in the molar ratio of $x : y = 2 : 1$. In the case of $T_i$ = 45$^\circ$C, it has been found that both Li and HMDA are co-intercalated locally at the edge of FeSe crystals, indicating that both Li and HMDA are hard to diffuse into the inside of FeSe crystals at 45$^\circ$C. In the case of $T_i$ = 100$^\circ$C, on the other hand, it has been found that both Li and HMDA diffuse into the inside of FeSe crystals, so that $T_c$ tends to increase with increasing $x$ from ~30 K at $x$ = 1 up to 38 K at $x$ = 2 owing to the increase of electron carriers doped from Li into the FeSe layers.
COULD SXP 1062 BE AN ACCRETING MAGNETAR?

In this work we explore the possible evolutionary track of the neutron star in the newly discovered Be/X-ray binary SXP 1062, which is believed to be the first X-ray pulsar associated with a supernova remnant. Although no cyclotron feature has been detected to indicate the strength of the neutron star's magnetic field, we show that it may be ≳ 1014 G. If so, SXP 1062 may belong to the accreting magnetars in binary systems. We attempt to reconcile the short age and long spin period of the pulsar taking account of different initial parameters and spin-down mechanisms of the neutron star. Our calculated results show that to spin down to a period ∼1000 s within 10–40 kyr requires efficient propeller mechanisms. In particular, the model for angular momentum loss under energy conservation seems to be ruled out.
Elements Selection for Auxiliary Array in the Adaptive Sidelobe Canceller Radar System

In a recent paper, the conventional sidelobe canceller radar system was developed by replacing the separate auxiliary antennas by few elements at the center of the main antenna array. The modified system with reused elements was associated with some attenuation in the desired signal due to the emerging correlation between the signals that exists in the main and the reused array elements. This problem was solved by imposing some constraints on the array pattern of the reused elements. In this paper, few of the side elements of the main array are employed as the auxiliary antennas. This new proposed configuration is called sided-elements. Unlike the previous centered-elements configuration, the proposed sided-elements configuration offers more desired features since the pattern of the side elements has sidelobes of similar widths of those of the main array. Moreover, a better diversity is obtained due to the wider separation between the two groups of elements at both sides of the main array. Simulation results fully confirm the effectiveness of the new proposed sided-elements configuration for suppressing the undesired interfering signals and retaining the desired signal undistorted.
