Cyclic-anion salt for high-voltage stable potassium-metal batteriesOA

Electrolyte anions are critical for achieving high-voltage stable potassium-metal batteries(PMBs).However,the common anions cannot simultaneously prevent the formation of ’dead K’ and the corrosion of Al current collector,resulting in poor cycling stability.Here,we demonstrate cyclic anion of hexafluoropropane-1,3-disulfonimide-based electrolytes that can mitigate the ’dead K’ and remarkably enhance the high-voltage stability of PMBs.Particularly,even using low salt concentration(0.8 M) and addi...     

Rollback,scissor-like closure of the Mongol-Okhotsk Ocean and formation of an orocline:magmatic migration based on a large archive of age dataOA

Tracing the closure of oceans with irregular margins and the formation of an orocline are crucial for understanding plate reconstruction and continental assembly.The eastern Central Asian Orogenic Belt,where the Mongol-Okhotsk orocline is situated,is one of the world’s largest magmatic provinces.Using a large data set of U-Pb zircon ages,we updated the timing of many published igneous rocks,which allowed us to recognize tightly ’folded’ linear Carboniferous-Jurassic magmatic belts that wrap arou...     

新闻专业精神不可或缺

新冠肺炎疫情发生以后.人们迫切期待获知更多信息。以往在单一事件中较为活跃的自媒体此次“退居二线”,未能提供更多让公众感到“解渴”的信息。而专业机构媒体由于具备专业的素材收集能力,调查采访能力、信息呈现能力,在疫情报道中凸显了自身的价值,也给新闻从业者以信心,更充分证明新闻专业精神在融媒体时代的不可或缺。以武汉“封城”为标志.疫情防控的应急机制被充分激活。

新浪微博替代计量指标特征分析

通过对新浪微博替代计量指标进行统计分析,探索中文环境下替代计量指标的特征和规律。研究发现:新浪微博替代计量指标覆盖率不足1%,但由于追踪时间和追踪对象的局限,该数字可能被严重低估;新浪微博关注和讨论较多的论文来自"综合""生物化学、遗传学与分子生物学""保健科学""医学"及"生命科学"等学科;新浪微博替代计量指标的期刊分布满足对数曲线规律,除著名的综合性期刊如Nature等,预印本平台arXiv和开放存取期刊PLoS ONE等也获得了较多关注,生物学和医学的"明星期刊"最多;新浪微博主要关注最新论文,正式出版180天内受到关注的论文比例高达68.66%,同时也会关注经典论文;新浪微博发布者倾向宣传、推介和评论贴近生活、趣味性强、实用性高、涉及生命健康的学术论文,传递出引文无法体现的社会价值和学术价值;新浪微博替代计量指标呈现出显著的离散和集中分布特点,5.1%的学术论文获得了50%的新浪微博关注。此外,受新浪微博关注的论文在全球范围内获得远高于平均水平的关注度。     

利益论视角下的高校学术腐败问题

高校学术腐败有多种成因因素,其根本原因关涉到人生存和发展的根本性问题——利益问题。本文在对利益冲突与学术腐败泛化的基本阐述之上,对高校教师的利益需求和高校学术评价机制进行深入分析,最后提出合理利用利益机制,整体化、制度化解决高校学术腐败问题的基本思想。并强调,利益协调是社会和谐发展的基础,是制约我们有效解决学术腐败问题的关键所在。     

Impaired motor control after sport-related concussion could increase risk for musculoskeletal injury: Implications for clinical management and rehabilitation

This review presents a conceptual framework and supporting evidence that links impaired motor control after sport-related concussion(SRC)to increased risk for musculoskeletal injury.Multiple studies have found that athletes who are post-SRC have higher risk for musculoskeletal injury compared to their counterparts.A small body of research suggests that impairments in motor control are associated with musculoskeletal injury risk.Motor control involves the perception and processing of sensory information and subsequent coordination of motor output within the central nervous system to perform a motor task.Motor control is inclusive of motor planning and motor learning.If sensory information is not accurately perceived or there is interference with sensory information processing and cognition,motor function will be altered,and an athlete may become vulnerable to injury during sport participation.Athletes with SRC show neuroanatomic and neurophysiological changes relevant to motor control even after meeting return to sport criteria,including a normal neurological examination,resolution of symptoms,and return to baseline function on traditional concussion testing.In conjunction,altered motor function is demonstrated after SRC in muscle activation and force production,movement patterns,balance/postural stability,and motor task performance,especially performance of a motor task paired with a cognitive task(i.e.,dual-task condition).The clinical implications of this conceptual framework include a need to intentionally address motor control impairments after SRC to mitigate musculoskeletal injury risk and to monitor motor control as the athlete progresses through the return to sport continuum.
