description: A highly porous metal–organic frame work Cu3 BTC2 (copper(II)-benzene-1,3,5-tricarboxylate) that is known as MOF-199 was synthesized from the reaction of 1,3,5-benzenetricarboxylic acid and Cu(OAc)2·H2O by a solvothermal method and characterized by several techniques including FT-IR, XRD, EDX and scanning electron microscopy. The MOF-199 used as an efficient catalyst for one-pot synthesis of thiols by domino reactions of aryl halides and thiourea, and subsequently conversion to aryl alkyl sulfides and diaryl disulfides in polyethylene glycols (PEGs). A variety of aryl alkyl sulfides can be obtained in good to excellent yields in a relatively short reaction time and in the presence of the trace amount of catalyst. Also, the catalyst can be separated from the reaction mixture by decanting, and be reused without significant degradation in catalytic activity.

description: Given a conical affine special Kähler (CASK) manifold together with a compatible mutually local variation of BPS structures, one can construct a quaternionic-Kähler (QK) manifold. We call the resulting QK manifold an instanton corrected c-map space. Our main aim is to study the isometries of a subclass of instanton corrected c-map spaces associated to projective special real (PSR) manifolds with a compatible mutually local variation of BPS structures. We call the latter subclass instanton corrected q-map spaces. In the setting of Calabi-Yau compactifications of type IIB string theory, instanton corrected q-map spaces are related to the hypermultiplet moduli space metric with perturbative corrections, together with worldsheet, D(-1) and D1 instanton corrections. In the physics literature, it has been shown that the hypermultiplet metric with such corrections must have an $\mathrm{SL}(2,\mathbb{Z})$ acting by isometries, related to S-duality. We give a mathematical treatment of this result, specifying under which conditions instanton corrected q-map spaces carry an action by isometries by $\mathrm{SL}(2,\mathbb{Z})$ or some of its subgroups. We further study the universal isometries of instanton corrected q-map spaces, and compare them to the universal isometries of tree-level q-map spaces. Finally, we give an explicit example of a non-trivial instanton corrected q-map space with full $\mathrm{SL}(2,\mathbb{Z})$ acting by isometries and admitting a quotient of finite volume by a discrete group of isometries.

description: Two new complexes, bis(N-(2-phenylethyl)-N-(4-fluorobenzyl)dithiocarbamato-S,S′)zinc(II) (1) and bis(N-(2-phenylethyl)-N-(4-chlorobenzyl)dithiocarbamato-S,S′)zinc(II) (2), have been synthesized and characterized by various physicochemical techniques. Structure of 1 has been determined by single crystal X-ray diffraction. Complex 1 is a dimer. Zinc atom is four coordinated with a distorted tetrahedral environment. Geometry optimization, geometrical parameters, molecular electrostatic potential (MEPs) and frontier molecular orbital analysis of dimeric and monomeric structures of 1 have been carried out by DFT methods and compared with the experimental X-ray diffraction data. The noncovalent interactions in the complex 1 have been analyzed using Hirshfeld surface analysis. 1 and 2 have been used as single source precursors for the preparation of zinc sulfide and zinc oxide nanoparticles. As-prepared zinc sulfides and zinc oxides have been characterized by powder X-ray diffraction (PXRD), scanning electron microscope (SEM), UV–vis absorption, photoluminence and energy dispersive X-ray spectroscopy (EDS). X-ray diffraction study reveals that zinc sulfides and zinc oxides are composed of rhombohedral and hexagonal phases, respectively. Photocatalytic activities of zinc sulfides and zinc oxides were evaluated by degradation of rhodamine B in aqueous solution under UV light irradiation. The results demonstrated the capability of zinc sulfides and zinc oxides as photocatalyst under UV irradiation to degrade the dye.

description: Here, we study the generalized second law (GSL) of thermodynamics in the framework of massive gravity. To do this, we consider a FRW universe filled only with matter and enclosed by the apparent horizon. In addition, we consider two models including generalized massive gravity (GMG) as well as dRGT massive gravity on de Sitter. For both models, we first study the dynamics of background cosmology and then explore the validity of GSL. We conclude that for the selected values of model parameters the GSL is respected.

description: Arbuscular mycorrhizal fungi (AMF) proliferate in soils and are known to affect soil structure. Although their contribution to structure is extensively investigated, the consequences of those processes for soil water extractability and transport has, so far, gained surprisingly little attention. Therefore we asked, whether AMF can affect water retention and unsaturated hydraulic conductivity under exclusion of root ingrowth, in order to minimize plant driven effects. We carried out experiments with tomato inoculated with Rhizoglomus irregulare in a soil substrate with sand and vermiculite that created variation in colonization by mixed pots with wild type (WT) plants and mycorrhiza resistant (RMC) mutants. Sampling cores were introduced and used to assess substrate moisture retention dynamics and modeling of substrate water retention and hydraulic conductivity. AMF reduced the saturated water content and total porosity, but maintained air filled porosity in soil spheres that excluded root ingrowth. The water content between field capacity and the permanent wilting point (6–1500 kPa) was only reduced in mycorrhizal substrates that contained at least one RMC mutant. Plant available water contents correlated positively with soil protein contents. Soil protein contents were highest in pots that possessed the strongest hyphal colonization, but not significantly affected. Substrate conductivity increased up to 50% in colonized substrates in the physiologically important water potential range between 6 and 10 kPa. The improvements in hydraulic conductivity are restricted to substrates where at least one WT plant was available for the fungus, indicating a necessity of a functional symbiosis for this effect. We conclude that functional mycorrhiza alleviates the resistance to water movement through the substrate in substrate areas outside of the root zone.
Gilbert damping in metallic ferromagnets from Schwinger-Keldysh field theory: Intrinsically nonlocal and nonuniform, and made anisotropic by spin-orbit coupling

description: Understanding the origin of damping mechanisms in magnetization dynamics of metallic ferromagnets is a fundamental problem for nonequilibrium many-body physics of systems where quantum conduction electrons interact with localized spins assumed to be governed by the classical Landau-Lifshitz-Gilbert (LLG) equation. It is also of critical importance for applications, as damping affects energy consumption and speed of spintronic and magnonic devices. Since the 1970s, a variety of linear-response and scattering theory approaches have been developed to produce widely used formulas for computation of spatially-independent Gilbert scalar parameter as the magnitude of the Gilbert damping term in the LLG equation. The largely unexploited for this purpose Schwinger-Keldysh field theory (SKFT) offers additional possibilities, such as to rigorously derive an extended LLG equation by integrating quantum electrons out. Here we derive such equation whose Gilbert damping for metallic ferromagnets is nonlocal, i.e., dependent on all localized spins at a given time, and nonuniform, even if all localized spins are collinear and spin-orbit coupling (SOC) is absent. This is in sharp contrast to standard lore, where nonlocal damping is considered to emerge only if localized spins are noncollinear; for such situations, direct comparison on the example of magnetic domain wall shows that SKFT-derived nonlocal damping is an order of magnitude larger than the previously considered one. Switching on SOC makes such nonlocal damping anisotropic, in contrast to standard lore where SOC is usually necessary to obtain nonzero Gilbert damping scalar parameter. Our analytical formulas, with their nonlocality being more prominent in low spatial dimensions, are fully corroborated by numerically exact quantum-classical simulations.

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.

description: Using the near-detailed-balance distribution function obtained in our recent work, we present a set of covariant gravito-thermal transport equations for neutral relativistic gases in a generic stationary spacetime. All relevant tensorial transport coefficients are worked out and are presented using some particular integration functions in $(α,ζ)$, where $α= -βμ$ and $ζ=βm$ is the relativistic coldness, with $β$ being the inverse temperature and $μ$ being the chemical potential. It is shown that the Onsager reciprocal relation holds in the gravito-thermal transport phenomena, and that the heat conductivity and the gravito-conductivity tensors are proportional to each other, with the coefficient of proportionality given by the product of the so-called Lorenz number with the temperature, thus proving a gravitational variant of the Wiedemann-Franz law. It is remarkable that, for strongly degenerate Fermi gases, the Lorenz number takes a universal constant value $L=π^2/3$, which extends the Wiedemann-Franz law into the Wiedemann-Franz-Lorenz law.

description: The shear viscosity of quark gluon plasma is customarily estimated in the literature using kinetic theory, which, however, is well known to break down for dense interacting systems. Here we propose an alternative theoretical approach based on recent advances in the physics of dense interacting liquid-like systems, which is valid for strongly-interacting and arbitrarily dense relativistic systems. With this approach, the viscosity of strongly interacting dense heavy-quarks plasma is evaluated analytically, at the level of special relativity. For QGP well above the confinement temperature, the theory predicts that the viscosity increases with the cube of temperature, in agreement with evidence.

description: A new series of ruthenium(II) carbonyl complexes, [RuCl(CO)(EPh3)2(L1-2)] (1–4) (E = P or As; H2L1 = salicylaldazine, H2L2 = 2-hydroxynaphthaldazine), have been assembled from ruthenium(II) precursors [RuHCl(CO)(EPh3)3] and bidentate ON donor Schiff base ligands (H2L1-2). Both ligands and their new ruthenium(II) complexes have been characterized by elemental analyses, spectroscopic methods (UV, IR, NMR (1H, 13C, 31P) as well as ESI mass spectrometry. The molecular structures of H2L1 and 1 have been confirmed by single crystal X-ray diffraction. Based on the above studies, an octahedral coordination geometry around the metal center has been proposed for 1–4. To investigate the catalytic effectiveness of 1–4, the complexes have been used as catalysts in β-alkylation of secondary alcohols with primary alcohols and synthesis of quinolines. The effect of solvent, time, base, catalyst loading, and substituent of the ligand moiety on the reaction was studied. Notably, 1 was a more efficient catalyst toward alkylation of a wide range of alcohols and quinolines synthesis. The reusability of the catalyst was checked and the results showed up to six catalytic runs without significant loss of activity.

description: Meso-tetrakis(N-methyl pyridinium-4-yl)porphyrin (TMPyP) intercalates between the base-pairs of DNA at a low [TMPyP]/[DNA base] ratio in aqueous solutions and molecular crowding conditions, which is induced by the addition of Poly(ethylene glycol) (PEG). Studied DNA-binding drugs, including TMPyP, 9-aminoacridine, ethidium bromide, and DAPI (4′,6-diamidino-2-phenylindole) showed similar binding properties in the presence or absence of PEG molecules which is examined by circular and linear dichroism. According to the LDr (reduced linear dichroism) results of the binding drugs examined in this work, PEG molecules induced no significant change compared to their binding properties in aqueous buffering systems. These results suggest that the transition moments are not expected to be perturbed significantly by PEG molecules. In this study, the experimental conditions of PEG 8000 were maintained at 35% (v/v) of total reaction volume, which is equal to the optimal molar concentration (0.0536 M as final concentration for PEG 8000) to maintain suitable cell-like conditions. Therefore, there was no need to focus on the conformational changes of the DNA helical structure, such as forming irregular aggregate structures, induced by large quantities of molecular crowding media itself at this stage.

description: We perform the first global quantum chromodynamics (QCD) analysis of dihadron production for a comprehensive set of data in electron-positron annihilation, semi-inclusive deep-inelastic scattering, and proton-proton collisions, from which we extract simultaneously the transversity distributions of the nucleon and $π^+π^-$ dihadron fragmentation functions. We incorporate in our fits known theoretical constraints on transversity, namely, its small-$x$ asymptotic behavior and the Soffer bound. We furthermore show that lattice-QCD results for the tensor charges can be successfully included in the analysis. This resolves the previously reported incompatibility between the tensor charges extracted from dihadron production data and lattice QCD. We also find agreement with results for the transversity and tensor charges obtained from measurements on single-hadron production. Overall, our work demonstrates for the first time the universal nature of all available information for the transversity distributions and the tensor charges of the nucleon.

Subjects: Organizational Behavioral Psychology

description: This program of research explored the organisational determinants of work-related road traffic injury in light vehicle fleets. The landscape of risk management in workplace road safety in Australia and organisational practices that influence safe driver behaviour were investigated. Key findings included that safe driving is influenced by factors at multiple levels, including senior managers, supervisors and individual fleet drivers and workplace road safety is not well integrated within current risk management practices or operational activities within organisations. The findings encourage reform in prevention approaches to workplace road safety, where intervention needs to focus at the driver, employer and regulatory levels.

description: The identification of protein crystals naturally occurring inside cells and organisms has opened a window for a new type of macromolecular crystallography (MX) and structural biology, referred to as in vivo MX. In the past decade, efforts were provided in getting deeper insights into the yet uncontrollable events dictating in vivo crystal growth, by further developing sample handling and delivery procedures and applying these techniques to the structure determination and analysis of readily available ivMX systems. To facilitate the use of ivMX by the larger community, milestones for the implementation of a complete pipeline has been set at Synchrotron SOLEIL (France). In the current presentation, I will be introducing the hows and whys of ivMX, the basics behind the platform and the promising results obtained while attempting to fully characterize the events involved in these fascinating natural events.

Parallel framework for Dynamic Domain Decomposition of Data Assimilation problems a case study on Kalman Filter algorithm

description: We focus on Partial Differential Equation (PDE) based Data Assimilatio problems (DA) solved by means of variational approaches and Kalman filter algorithm. Recently, we presented a Domain Decomposition framework (we call it DD-DA, for short) performing a decomposition of the whole physical domain along space and time directions, and joining the idea of Schwarz' methods and parallel in time approaches. For effective parallelization of DD-DA algorithms, the computational load assigned to subdomains must be equally distributed. Usually computational cost is proportional to the amount of data entities assigned to partitions. Good quality partitioning also requires the volume of communication during calculation to be kept at its minimum. In order to deal with DD-DA problems where the observations are nonuniformly distributed and general sparse, in the present work we employ a parallel load balancing algorithm based on adaptive and dynamic defining of boundaries of DD -- which is aimed to balance workload according to data location. We call it DyDD. As the numerical model underlying DA problems arising from the so-called discretize-then-optimize approach is the constrained least square model (CLS), we will use CLS as a reference state estimation problem and we validate DyDD on different scenarios.

description: Processes involving ultrafast laser driven electron-phonon dynamics play a fundamental role in the response of quantum systems in a growing number of situations of interest, as evidenced by phenomena such as strongly driven phase transitions and light driven engineering of material properties. To show how these processes can be captured from a computational perspective, we simulate the transient absorption spectra and high harmonic generation signals associated with valley selective excitation and intra-band charge carrier relaxation in monolayer hexagonal boron nitride. We show that the multi-trajectory Ehrenfest dynamics approach, implemented in combination with real-time time-dependent density functional theory and tight-binding models, offers a simple, accurate and efficient method to study ultrafast electron-phonon coupled phenomena in solids under diverse pump-probe regimes which can be easily incorporated into the majority of real-time ab-initio software packages.

OPTIMIZATION OF SUPERPLASTICIZER DOSAGE AND EFFECTS WITH LOCALLY PRODUCED CEMENTS ON READY-MIX CONCRETE PROPERTIES
Creators: name: DANIEL MAMO

Year: 2020
Subjects: Superplasticizer, dosage, cement, concrete strength, a ready-mixed concrete.

description: Concrete is the most common building material that is used prominently in construction industry. It
 can be cast in any desired shape and fashion and should be workable whether on- site or in ready mix
 concrete production. To achieve better performance and desired proprieties of concrete, the use of
 chemical admixtures is priceless choice in concrete production. While, there are common problems
 facing to optimize superplasticzer dosage with various types of cement to produce desirable
 properties of fresh and hardened concrete due to lack of practices in construction industry in our
 country.
 The purpose of this research was determining optimum Superplasticizer dosage for desired
 workability using Marsh Cone Test at pre-determined water cement ratio. It was also analysis the
 effect and influences of Superplasticizer dosage on concrete properties. Slump Cone test and testing
 machine were used to determine such properties of concrete. The first conclusion that was drawn
 from the research was deciding optimum dosage on cement slurry which was prepared using different
 types of Super plasticizer and Cements for variable water cement ratio. Secondly, the test were
 carried out to see effects of Superplasticizer dosage on improvement of workability and flowablity of
 fresh concrete in specified doses. Also, it was also noticed changes of hardened concrete properties
 using mechanical tests.
 Using 0.45 and 0.40 water-cement ratio, optimum dosage of Superplasticizer (ODS) has found out,
 with respect to different Superplasticzers on different brand of cement paste mix.
 Secondly, it also observed the effect of superplasticzer dosage for pre- determined quantity (0.5%,
 1.0%, 1.5% and 2.0%) on hardened concrete strength in addition to fresh concrete characteristics.
 Thirdly, the demand of water reduced by 20%, 23%, 27% and 30% from total mix water using
 0.5%,1.0%,1.5% and 2.0% of Superplasticizer respectively in concrete mix.
 Generally, Superplasticzer is playing vitally role to achieve better physical properties and quality of
 concrete, and resolving challenges in undesirable conditions during concrete work operations. Despite
 these facts, over dosage of SP were found to deteriorate the properties of concrete with indication of
 lower compressive strength and higher porosity due to bleeding and segregation occurrences.

description: Orbital angular momentum of light is regarded as a valuable resource in quantum technology, especially in quantum communication and quantum sensing and ranging. However, the OAM state of light is susceptible to undesirable experimental conditions such as propagation distance and phase distortions, which hinders the potential for the realistic implementation of relevant technologies. In this article, we exploit an enhanced deep learning neural network to identify different OAM modes of light at multiple propagation distances with phase distortions. Specifically, our trained deep learning neural network can efficiently identify the vortex beam's topological charge and propagation distance with 97% accuracy. Our technique has important implications for OAM based communication and sensing protocols.

description: Minor mergers are common in galaxy clusters. They have the potential to create sloshing cold fronts (SCFs) in the intracluster medium (ICM) of the cluster. However, the resilience of SCFs to subsequent minor mergers is unknown. Here we investigate the extent to which SCFs established by an off-axis minor merger are disrupted by a subsequent minor merger. We perform a suite of 13 hydrodynamic + N-body simulations of idealised triple cluster mergers in which we vary the approach direction and impact parameter of the tertiary cluster. Except for ~1 Gyr after the first core passage of the tertiary cluster, clear SCFs are present in all merger configurations. Subsequent head-on minor mergers reduce the number of SCFs significantly, while subsequent off-axis minor mergers only moderately reduce the number of SCFs. In particular, outer (>~500 kpc) SCFs are resilient. The results of this work indicate that SCFs are easily formed in the course of a minor merger and are long-lived even if a further minor merger takes place. SCFs thus should be ubiquitous, but deriving the merger history of a given cluster based on its observed SCFs might be more complex than previously thought.

description: Introduction. La pandémie actuelle de COVID-19 est due à l’apparition d’un nouveau coronavirus émergent SARS-CoV-2, famille des Coronaviridae et sous-famille des Orthocoronavirinae. Ce virus a été signalé pour la première fois en décembre 2019 en Chine. Bien que signalée par plusieurs pays chez plusieurs espèces animales, la COVID-19 est une maladie transmise principalement d’humain à humain. Par ailleurs, le SARS-CoV-2 ainsi que son ARN ont été détectés dans des excrétions corporelles autres que la salive, telles les urines et les matières fécales déversées dans les eaux usées. Revue bibliographique. Dans ce cadre, cet article présente une synthèse des revues bibliographiques sur le SARS-CoV-2 en milieu aquatique, tout en soulignant les généralités sur le SARS-CoV-2, les éventuelles sources de contaminations potentielles du SARS-CoV-2 dans les milieux hydriques, la viabilité du SARS-CoV-2 dans le milieu aquatique, les espèces réceptrices et les impacts du SARS-CoV-2 sur les écosystèmes aquatiques. Conclusion. Nous rassemblons les principales informations relatives au SARS-CoV-2 jugées importantes à retenir, et nous soulignons l’intérêt de poursuivre les recherches dans ce domaine pour évaluer les dangers que représente le SARS-CoV-2 pour les écosystèmes aquatiques. The hazards of SARS-CoV-2 for aquatic ecosystems Abstract Introduction. The current COVID-19 pandemic is due to a new emerging coronavirus SARS-CoV-2, belonging to the Coronaviridae family and to the Orthocoronavirinae subfamily. This virus was first reported in December 2019 in China. Although reported by several countries in several animal species, COVID-19 is a disease transmitted from human to human. Moreover, SARS-CoV-2 virus and its RNA were detected in body excretions besides saliva, such as urine and fecal matter discharged into sewage. Bibliographic review. Within this framework, this article aims to synthesize the bibliographical reviews on SARS-CoV-2 in aquatic environment. It will underline the generalities on SARS-CoV-2, the possible sources of potential contaminations of SARS-CoV-2 in water environment, the viability of SARS-CoV-2 in aquatic environment, the receptive species and the impacts of SARS-CoV-2 on the aquatic ecosystems. Conclusion. We compile key information about SARS-CoV-2 that are considered important to remember and highlight the importance of further research in this area in order to assess the hazards of SARS-CoV-2 on aquatic ecosystems.

description: Quantum phase estimation (QPE) serves as a building block of many different quantum algorithms and finds important applications in computational chemistry problems. Despite the rapid development of quantum hardware, experimental demonstration of QPE for chemistry problems remains challenging due to its large circuit depth and the lack of quantum resources to protect the hardware from noise with fully fault-tolerant protocols. In the present work, we take a step towards fault-tolerant quantum computing by demonstrating a QPE algorithm on a Quantinuum trapped-ion computer. We employ a Bayesian approach to QPE and introduce a routine for optimal parameter selection, which we combine with a $[[ n+2,n,2 ]]$ quantum error detection code carefully tailored to the hardware capabilities. As a simple quantum chemistry example, we take a hydrogen molecule represented by a two-qubit Hamiltonian and estimate its ground state energy using our QPE protocol. In the experiment, we use the quantum circuits containing as many as 920 physical two-qubit gates to estimate the ground state energy within $6\times 10^{-3}$ hartree of the exact value.

Chronique d’une mort annoncée : le destin funeste des disciplines de médecine tropicale françaises et ses conséquences dans la lutte contre les inégalités sanitaires en Afrique

description: Depuis la fin des années 1990, nous assistons en France à une évolution lente conduisant à la disparition des disciplines liées aux maladies tropicales. Au niveau hospitalier, elle se traduit par la dilution progressive des services cliniques consacrés au traitement des maladies infectieuses et tropicales au sein d’un pôle infectieux ou de médecine interne, et, en biologie médicale, par le remplacement des biologistes parasitologues ayant acquis une spécialisation en mycologie, par des biologistes mycologues ayant acquis une spécialisation en parasitologie. Cette orientation peut sembler normale, la réduction des compétences en diagnostic parasitologique et clinique étant liée au succès des mesures d’hygiène et de contrôle des produits alimentaires, qui ont entraîné la quasi-disparition, dans notre pays, de parasitoses autochtones telles que la fasciolose, le tæniasis, ou l’amibiase. Priorité est donc donnée à la mycologie, en particulier aux infections respiratoires, prédominantes dans une population protégée et vieillissante. Fallait-il pour autant le faire au détriment des compétences en diagnostic et en soin des maladies touchant les populations des pays à ressources limitées ? Chronicle of a death foretold: the fateful fate of French tropical medicine disciplines and its consequences in the fight against health inequalities in Africa Abstract Since the end of the 1990s, we have witnessed a slow evolution in France leading to the disappearance of disciplines related to tropical diseases. At the hospital level, this is reflected by the progressive inclusion of clinical services dedicated to the treatment of infectious and tropical diseases within an infectious diseases or internal medicine pole, and, in medical biology, by the replacement of parasitological biologists having acquired a specialization in mycology, by mycological biologists having acquired a specialization in parasitology. This orientation may seem normal, the reduction of skills in parasitological and clinical diagnosis being linked to the success of hygiene and food control measures, which have led to the virtual disappearance, in our country, of autochthonous parasitic diseases such as fasciolosis, taeniasis, or amoebiasis. Priority is therefore given to mycology, especially respiratory infections, which are predominant in protected and aging populations. However, should this be done at the expense of diagnostic and treatment skills for diseases affecting populations in countries with limited resources?

description: Early diagnosis of mental disorders and intervention can facilitate the prevention of severe injuries and the improvement of treatment results. Using social media and pre-trained language models, this study explores how user-generated data can be used to predict mental disorder symptoms. Our study compares four different BERT models of Hugging Face with standard machine learning techniques used in automatic depression diagnosis in recent literature. The results show that new models outperform the previous approach with an accuracy rate of up to 97%. Analyzing the results while complementing past findings, we find that even tiny amounts of data (like users' bio descriptions) have the potential to predict mental disorders. We conclude that social media data is an excellent source of mental health screening, and pre-trained models can effectively automate this critical task.

description: We investigate the holographic complexity of CFTs compactified on a circle with a Wilson line, dual to magnetized solitons in AdS$_4$ and AdS$_5$. These theories have a confinement-deconfinement phase transition as a function of the Wilson line, and the complexity of formation acts as an order parameter for this transition. Through explicit calculation, we show that proposed complexity functionals based on volume and action obey a scaling relation with radius of the circle and further prove that a broad family of potential complexity functionals obeys this scaling behavior. As a result, we conjecture that the scaling law applies to the complexity of conformal field theories on a circle in more general circumstances.

description: Quantum inverse problem is defined as how to determine a local Hamiltonian from a single eigenstate? This question is valid not only in Hermitian system but also in non-Hermitian system. So far, most attempts are limited to Hermitian systems, while the possible non-Hermitian solution remains outstanding. In this work, we generalize the quantum covariance matrix method to the cases that are applicable to non-Hermitian systems, through which we are able to explicitly reconstruct the non-Hermitian parent Hamiltonian from an arbitrary pair of biorthogonal eigenstates. As concrete examples, we successfully apply our approach in spin chain with Lee-Yang singularity and a non-Hermitian interacting fermion model. Some generalization and further application of our approach are also discussed. Our work provides a systematical and efficient way to construct non-Hermitian Hamiltonian from a single pair of biorthogonal eigenstates and shed light on future exploration on non-Hermitian physics.
