    Abstract Hydrogen sulïŹde (H2S) is recognized as one of three gasotransmitters together with nitric oxide (NO) and carbon monoxide (CO). As a signaling molecule, H2S plays an important role in physiology and shows great potential in pharmaceutical applications. Along this line, there is a need for the development of H2S prodrugs for various reasons. In this review, we summarize different H2

    Les quatre textes ont en commun de prĂ©senter certaines Ă©volutions rĂ©centes de l’histoire politique en Allemagne. Ils prennent tous position face Ă  trois tournants historiographiques. La notion d’histoire culturelle du politique peut servir d’emblĂšme au premier de ces tournants : le politique est envisagĂ© non plus comme une succession d’évĂ©nements ni comme le fruit de dĂ©terminations structurelles dont il serait la superstructure ou l’écume, mais comme l’expression de valeurs et de procĂ©dures o..

    The influence of metabolic syndrome on age-related hearing loss from the perspective of mitochondrial dysfunction

    Get PDF
    With the increase in life expectancy in the global population, aging societies have emerged in many countries, including China. As a common sensory defect in the elderly population, the prevalence of age-related hearing loss and its influence on society are increasing yearly. Metabolic syndrome is currently one of the main health problems in the world. Many studies have demonstrated that metabolic syndrome and its components are correlated with a variety of age-related diseases of the peripheral sensory system, including age-related hearing loss. Both age-related hearing loss and metabolic syndrome are high-prevalence chronic diseases, and many people suffer from both at the same time. In recent years, more and more studies have found that mitochondrial dysfunction occurs in both metabolic syndrome and age-related hearing loss. Therefore, to better understand the impact of metabolic syndrome on age-related hearing loss from the perspective of mitochondrial dysfunction, we reviewed the literature related to the relationship between age-related hearing loss and metabolic syndrome and their components to discern the possible role of mitochondria in both conditions

    Alignment of the ATLAS Inner Detector in Run 2

    The performance of the ATLAS Inner Detector alignment has been studied using pp collision data at v s = 13 TeV collected by the ATLAS experiment during Run 2 (2015-2018) of the Large Hadron Collider (LHC). The goal of the detector alignment is to determine the detector geometry as accurately as possible and correct for time-dependent movements. The Inner Detector alignment is based on the minimization of track-hit residuals in a sequence of hierarchical levels, from global mechanical assembly structures to local sensors. Subsequent levels have increasing numbers of degrees of freedom; in total there are almost 750,000. The alignment determines detector geometry on both short and long timescales, where short timescales describe movementswithin anLHCfill. The performance and possible track parameter biases originating from systematic detector deformations are evaluated. Momentum biases are studied using resonances decaying to muons or to electrons. The residual sagitta bias and momentum scale bias after alignment are reduced to less than similar to 0.1 TeV-1 and 0.9 x 10(-3), respectively. Impact parameter biases are also evaluated using tracks within jets

    Search for Higgs boson decays into two new low-mass spin-0 particles in the 4b channel with the ATLAS detector using pp collisions at √s = 13 TeV

    This paper describes a search for beyond the Standard Model decays of the Higgs boson into a pair of new spin-0 particles subsequently decaying into b -quark pairs, H → a a → ( b ÂŻ b ) ( b ÂŻ b ) , using proton-proton collision data collected by the ATLAS detector at the Large Hadron Collider at center-of-mass energy √ s = 13     TeV . This search focuses on the range 15     GeV ≀ m a ≀ 30     GeV , where the decay products are collimated; it is complementary to a previous search in the same final state targeting the range 20     GeV ≀ m a ≀ 60     GeV , where the decay products are well separated. A novel strategy for the identification of the a → b ÂŻ b decays is deployed to enhance the efficiency for topologies with small separation angles. The search is performed with 36     fb − 1 of integrated luminosity collected in 2015 and 2016 and sets upper limits on the production cross section of H → a a → ( b ÂŻ b ) ( b ÂŻ b ) , where the Higgs boson is produced in association with a Z boson

    A Skeleton-Based Rehabilitation Exercise Assessment System With Rotation Invariance

    No full text
    Automated exercise assessment is of great importance for patients under rehabilitation exercise who require professional guidance. Among the existing approaches, the skeleton-based assessment model that classifies the correctness of the exercise has attracted much attention due to its relative ease of implementation and convenience in use. However, there are two problems with this approach. The first problem is its sensitivity to the orientation of the human skeleton. To solve this problem, we propose a novel rotation-invariant descriptor, the dot product matrix of the human skeleton, and prove mathematically that this descriptor discards only the orientation message that we do not expect while preserving all other useful information. Lack of feedback from the system is the second problem, because the exercisers do not know which parts of their exercises are incorrect. Therefore, we develop a visualization method for our system based on Gradient-Weighted Class Activation Mapping (Grad-CAM) and an quantitative metric called Overlap Ratio (OvR) to measure the quality of the visualization result. To demonstrate the effect of our method, we conduct experiments on two public datasets and a self-generated push-up dataset. The experimental results show that our rotation-invariant descriptor can achieve absolute robustness to orientation even under severe angle perturbations. In terms of accuracy and OvR, our method even outperforms previous works in most cases, indicating that the rotation-invariant descriptor helps the assessment model to extract more stable features. The visualization results are also informative to correct the movements; some examples are presented in this paper. The code of this paper and our push-up dataset are publicly available at https://github.com/Kelly510/RehabExerAssess
