Auditory areas are recruited for naturalistic visual meaning in early deaf people
Authors: Zimmermann Maria , Cusack Rhodri , Bedny Marina , Szwed Marcin 
Published: May 2023

Abstract

Early deafness enhances responses of auditory cortices to non-auditory tasks, yet the nature of the reorganization is not well understood. Here, naturalistic stimuli were used to induce neural synchrony across early deaf and hearing individuals. Participants watched a silent animated film in an intact version and three versions with gradually distorted meaning. Differences between groups were observed in higher-order auditory cortices in all stimuli, with no significant effects in the primary auditory cortex. Comparison between levels of scrambling revealed a heterogeneity of function in secondary auditory areas. Both hemispheres showed greater synchrony for the intact movie than for low-level variants. However, the right hemisphere showed an increased inter-subject synchrony for the low-level movie variants, which was not present on the left. An event segmentation validated these results: the dynamics of the right secondary auditory cortex unfolded as shorter length events with more transitions than the left. It also uncovered a further left-right asymmetry: Only left-hemisphere patterns matched the patterns of the hippocampus, a brain region situated at the top of cortical hierarchy. Our results reveal how deaf subjects use their auditory cortex to process visual meaning.
Analysis of pore structure characteristics of coal and permeability sensibility based on CT scanning technology

Published: May 2023

Abstract
Complex pores and fissures are the main transportable channels of coal reservoir resources and key factors affecting the permeability of coal seams. Owing to different tectonic stresses, the development characteristics of pores and fissures in coal can differ significantly, which also results in differences in reservoir permeability. Therefore, analysing the influence of pore structure characteristics on coal-rock permeability is needed. In this study, four samples from the DaTong Coal Mine in the central and southern Qinshui Basin of Shanxi Province were selected for analysis. Combined computerised tomography (CT) scanning and digital image processing technology revealed the development characteristics, distribution rules, morphology, and structural differences of different coals. Based on the capillary seepage channel model and fractal geometry theory combined with the pore structure parameters obtained by CT scanning, the permeability was predicted. Furthermore, the control mechanism of the pore structure on coal permeability is discussed. The results showed that the coal porosity is positively correlated with pore diameter, pore volume, connectivity factor, and connectivity strength at the micrometer scale. Coal reservoir permeability is controlled by multiple factors, including pore size, pore volume, porosity, connectivity factor, connectivity strength, and fractal dimension, among which pore size has the most significant influence. After the complexity and connectivity of the micropore structure in coal rock were considered, the accuracy and applicability of the pore structure parameters obtained by CT scanning to predict the permeability were verified by comparing with the measured permeability.

Published: May 2023

Abstract
Background Laparoscopic cholecystectomy (LC) is a common surgical procedure. Intraoperative fluoroscopic visualisation of the extrahepatic bile duct using indocyanine green (ICG) shows great advantage in LC. However, most studies used small sample sizes and rarely included complex cases, such as acute cholecystitis or reoperation. We analysed the feasibility and safety of using ICG in the complex LC of 70 patients.Methods All patients were administered intravenously with 5 mg of ICG and divided into a long-term group and a short-term group according to the time of administration. The general condition, laboratory results, intraoperative fluorescence visualisation and surgical video of the patients were analysed.Results The two groups showed no significant differences in sex, age, body mass index, American society of anesthesiologists (ASA)score and laboratory results. No significant differences in the rates of gallbladder visualisation (P = 0.622), cystic duct visualisation (P = 0.782) and common bile duct visualisation (P = 0.073). The visualisation of the liver was better in the short-term group (P < 0.001), and the gallbladder bed dissection time (P = 0.026) was better in the short-term group than in the long-term group.Conclusions ICG-assisted complex LC can visualise the bile duct better than the cystic duct. It still has an obvious guiding role in the anatomy of triangulation. The short-term group is better in the visualisation of the liver and in the dissection of the gallbladder from the liver bed. So maybe the short duration of administration is more suitable for patients with complex LC.

Abstract
Background Repurposing dantrolene as a potential disease-modifying treatment for Alzheimer’s disease has been shown to be effective in amyloid transgenic mouse models but has not been examined in a model of tauopathy.Objective The effects of a nanoparticle intranasal formulation, the Eagle Research Formulation of Ryanodex (ERFR), in young adult and aged wild type and PS19 tau transgenic mice was investigated.Methods The bioavailability of intranasal ERFR was measured in 2 months and 9–12 month old C57BL/6J male mice. Mice received a single intranasal dose of ERFR and, after 20 min, blood and brain samples were collected. Dantrolene concentrations in the plasma and brain were analyzed by High Performance Liquid Chromatography. Animal behavior was examined in PS19 tau transgenic mice, with/without acrolein treatment to exacerbate cognitive deficits. Behavioral tests included cognition (cued and contextual fear conditioning, y-maze), motor function (rotarod), and olfaction (buried food test).Results Dantrolene concentration in the blood and brain decreased with age, though the decrease was greater in the blood resulting in a higher brain to blood concentration ratio. The behavioral assays showed no significant changes in cognition, olfaction or motor function in the PS19 mice compared to controls after chronic ERFR treatment even with acrolein treatment.Conclusion Our studies suggest that while we did not find PS19 mice to be a reliable Alzheimer animal model to test the therapeutic efficacy of dantrolene, the results suggest a potential for ERFR to be an effective chronic therapy for Alzheimer’s disease and that further studies are indicated.
Spin-Dependent Graph Neural Network Potential for Magnetic Materials

Published: May 2023

Abstract
The development of machine learning interatomic potentials has immensely contributed to the accuracy of simulations of molecules and crystals. However, creating interatomic potentials for magnetic systems that account for both magnetic moments and structural degrees of freedom remains a challenge. This work introduces SpinGNN, a spin-dependent interatomic potential approach that employs the graph neural network (GNN) to describe magnetic systems. SpinGNN consists of two types of edge GNNs: Heisenberg edge GNN (HEGNN) and spin-distance edge GNN (SEGNN). HEGNN is tailored to capture Heisenberg-type spin-lattice interactions, while SEGNN accurately models multi-body and high-order spin-lattice coupling. The effectiveness of SpinGNN is demonstrated by its exceptional precision in fitting a high-order spin Hamiltonian and two complex spin-lattice Hamiltonians with great precision. Furthermore, it successfully models the subtle spin-lattice coupling in BiFeO3 and performs large-scale spin-lattice dynamics simulations, predicting its antiferromagnetic ground state, magnetic phase transition, and domain wall energy landscape with high accuracy. Our study broadens the scope of graph neural network potentials to magnetic systems, serving as a foundation for carrying out large-scale spin-lattice dynamic simulations of such systems.

Authors: Yang HuaiZhi , Wang Lei , Zhao XinYi 
Published: May 2023

Abstract
The evolution of the vegetation growing season in the context of global warming is an important topic. This study investigates the evolution of climatic growing season of different land cover types in temperate China with 5°C as the limiting temperature in the past (1971–2010) and future (under RCP4.5 scenario). Results indicate that from 1971 to 2010, the length of climatic growing season in most regions of temperate China increased slightly, with earlier start dates of growing season as a feature. In RCP4.5, larger changes in the start of the climatic growing season can be found in East China and the Qinghai-Tibet Plateau; whereas area with predominant, changes in the end of growing season entail the central, southern and eastern parts of the Qinghai-Tibet Plateau and the mountains regions of Xinjiang, the number of days of change is more than 30 days. Woodland and grassland have similar mean growing season variation while grassland has a significantly larger scale of growing season lengthening due to its 30 + day delay in the end of the growing season.

Abstract
Fluorescence lifetime imaging microscopy (FLIM) is a powerful imaging technique that enables the visualization of biological samples at the molecular level by measuring the fluorescence decay rate of fluorescent probes. This provides critical information about molecular interactions, environmental changes, and localization within biological systems. However, creating high-resolution lifetime maps using conventional FLIM systems can be challenging, as it often requires extensive scanning that can significantly lengthen acquisition times. This issue is further compounded in three-dimensional (3D) imaging because it demands additional scanning along the depth axis. To tackle this challenge, we developed a novel computational imaging technique called light field tomographic FLIM (LIFT-FLIM). Our approach allows for the acquisition of volumetric fluorescence lifetime images in a highly data-efficient manner, significantly reducing the number of scanning steps required compared to conventional point-scanning or line-scanning FLIM imagers. Moreover, LIFT-FLIM enables the measurement of high-dimensional data using low-dimensional detectors, which are typically low-cost and feature a higher temporal bandwidth. We demonstrated LIFT-FLIM using a linear single-photon avalanche diode array on various biological systems, showcasing unparalleled single-photon detection sensitivity. Additionally, we expanded the functionality of our method to spectral FLIM and demonstrated its application in high-content multiplexed imaging of lung organoids. LIFT-FLIM has the potential to open up new avenues in both basic and translational biomedical research.

Published: May 2023

Abstract
Background Pituitary tumors are among the rare tumors of the central nervous system. With advances in screening, the incidence of pituitary tumors is increasing every year. The symptoms of pituitary tumors are similar to those of some common diseases, and it is common to miss the diagnosis, which can lead to serious complications, affect life expectancy and quality of life, and lead to poor prognosis due to side effects of adjuvant chemotherapy and radiotherapy. Therefore, the search for new biomarkers is important for the early diagnosis and treatment .Methods Datasets related to pituitary tumors from the GEO database were collected and integrated, firstly, DEG screening and GO, KEGG and GSEA enrichment analysis were performed, then LASSO and SVM-RFE algorithms were used to identify pituitary tumor-related signature genes in the training set, and ROC performance and gene expression differences were verified in the test set. Based on this, the immune infiltration differences were analyzed, and the correlation between signature genes and immune cells was studied.Results We finally screened 6 signature genes, including CNTNAP2, LHX3, RAB11FIP3, SOX9, TBX19 and TGFBR, whose expression showed differences, and the expression of signature genes was correlated with tumor infiltrating immune cells abundance gene expression.Conclusion In this study, 6 signature genes were screened to contribute to the development of immune-targeted therapeutic agents for the early diagnosis of pituitary tumor patients.

Published: May 2023

Abstract
A fundamental understanding of the electrochemical behavior of hybrid perovskite and nitrogen-doped (N-doped) carbon is essential for the development of perovskite-based electrocatalysts in various sustainable energy device applications. In particular, the selection and modification of suitable carbon support are important for enhancing the oxygen reduction reaction (ORR) of non-platinum group metal electrocatalysts in fuel cells. Herein, we address hybrid materials composed of three representative N-doped carbon supports (BP-2000, Vulcan XC-72 and P-CNF) with valid surface areas and different series of single, double and triple perovskites: Ba0.5Sr0.5Co0.8Fe0.2O3−δ (BSCF), (Pr0.5Ba0.5)CoO3−δ (PBCO), and Nd1.5Ba1.5CoFeMnO9−δ (NBCFM), respectively. The combination of NBCFM and N-doped BP-2000 produces a half-wave potential of 0.74 V and a current density of 5.42 mA cm− 2 at 0.5 V vs. reversible hydrogen electrode, comparable to those of the commercial Pt/C electrocatalyst (0.76 V, 5.21 mA cm− 2). Physicochemical and electrochemical investigations indicate that carbon successfully overcomes the insulating properties of perovskite. Simultaneously, N-doped carbon is essential to accelerate the ORR performance of hybrid perovskite-carbon materials.
Spatial-Temporal Evolution and Influencing Factors of Rural Financial Resource Allocation Efficiency in China
Authors: Zhang Yang , Guo Hua 
Published: May 2023

Abstract
China is faced with challenge of improving efficiency in rural financial resource allocation in rural revitalization. This research examines the spatial-temporal evolutions of the static and dynamic allocation efficiency (SAE and DAE) of financial resources in rural China and their influencing factors. The combination of a super-slack-based measure (SBM) model with the Malmquist productivity index (MPI) is used to evaluate SAE and DAE from 2000 to 2019, respectively. Also, the spatial econometric models are applied to estimate spatial effects and effects of influencing factors on SAE or DAE. The result shows that SAE and DAE has been fluctuant de-creasing from a temporal perspective, while the differences in SAE or DAE among provinces from a spatial perspective are gradually decreasing. In particular, SAE shows a spatial distribution pattern of "high in the south and low in the northwest" and spatial siphon effect, while DAE gradually evolved into three high-efficiency poles in Xinjiang, Inner Mongolia and Sichuan. Further analysis shows that the development of economy significantly limited SAE and DAE; the ratio of deposits to loans significantly increased SAE, while the proportion of agriculture and the convenience of commodity market transactions adversely affected SAE. In addition, the regional education level significantly increased DAE. This research may help to formulate a reasonable allocation of limited rural financial resources.
