Silicon has ultrahigh capacity,dendrite-free alloy lithiation mechanism and low cost and has been regarded as a promising anode candidate for solid-state battery.Owing to the low infiltration of solid-state electrolyte(SSE),not the unstable solid-electrolyte interphase(SEI),but the huge stress during lithiation-and delithiation-induced particle fracture and conductivity lost tend to be the main issues.In this study,starting with micron-Si,a novel monothetic carbon conductive framework and a MgO coating layer are designed,which serve as electron pathway across the whole electrode and stress releasing layer,respectively.In addition,the in situ reaction between Si and SSE helps to form a LiF-rich and mechanically stable SEI layer.As a result,the mechanical stability and charge transfer kinetics of the uniquely designed Si anode are significantly improved.Consequently,high initial Coulombic efficiency,high capacity and durable cycling stability can be achieved by applying the Si@MgO@C anode in SSB.For example,high specific capacity of 3224.6 mAh·g^(-1)and long cycling durability of 200 cycles are achieved.This work provides a new concept for designing alloy-type anode that combines surface coating on particle and electrode structure design.

图卷积由于其对图数据的强大表示能力被广泛应用于基于骨架的动作识别任务中.但是现有的图卷积方法在所有帧或通道上都使用共享的图拓扑进行特征聚合,这极大限制了图卷积网络的表示能力.为了解决这些问题,本文提出多维动态拓扑学习图卷积用于动态建模具有时序与通道特异性的拓扑结构.多维动态拓扑学习图卷积主要包含三个组成部分:纯粹节点拓扑学习图卷积(pure Joint topology learning Graph Convolution,J-GC)、动态时序特异性拓扑学习图卷积(Dynamic Temporal-Wise topology learning Graph Convolution,DTW-GC)和通道特异性拓扑学习图卷积(Channel-Wise topology learning Graph Convolution,CW-GC).特别地,在DTW-GC中使用了动态骨架拓扑建模方法(Dynamic Skeleton Topology Learning,DSTL),以高效地建模富含全局时空拓扑特征的动态骨架拓扑.将多维动态拓扑学习图卷积与多尺度时间卷积(Multi-Scale Temporal Convolution,MS-TC)相结合,本文构建了具有强大建模能力的图卷积网络.此外,为了对骨架数据的空间信息进行补充,本文额外引入了相对节点数据和相对骨骼数据进行多流网络的融合.本文所提出的方法在NTU-RGB+D与NTU-RGB+D 120数据集上分别取得了92.64%和89.29%的准确率,超过了当前最先进方法.

目的探讨Chir99021对大鼠牙髓干细胞(DPSCs)成骨诱导分化的影响及机制。方法原代分离大鼠DPSCs,利用荧光免疫法进行验证。设置不同浓度的Chir99021,通过CCK-8检测细胞增殖情况挑选最适浓度。利用茜素红染色验证细胞成骨诱导分化。最后通过Real-time PCR、Western blotting检测成骨诱导分化相关基因与蛋白无翅型MMTV整合位点家族成员1(Wnt1)、无翅型MMTV整合位点家族成员3A(Wnt3a)、β-连环蛋白(β-catenin)、轴抑制蛋白2抗体(Axin2)、骨钙素(OCN)、牙本质基质蛋白1(DMP1)的mRNA和蛋白表达情况。结果牙本质涎磷蛋白(DSPP)和干细胞标记物波形蛋白(vimentin)阳性表达,说明大鼠DPSCs分离成功。大鼠DPSCs成骨诱导后钙沉积物显著上升,加入糖原合成酶激酶-3β(GSK-3β)的小分子抑制剂Chir99021后钙沉积物明显减少。大鼠DPSCs成骨诱导分化后Wnt1、Wnt3a、β-catenin、Axin2、OCN和DMP1表达明显上升,而加入Chir99021后Wnt1、Wnt3a、β-catenin、Axin2、OCN和DMP1蛋白表达均显著下降。结论Chir99021对诱导7 d后的大鼠DPSCs成骨诱导分化有一定的抑制作用。

Objective This study aimed to summarize the characteristics and methodological quality of systematic reviews on the application of artificial intelligence(AI)in clinical diagnosis and treatment.Methods We systematically searched seven English-and Chinese-language literature databases to identify sys-tematic reviews on the application of AI,deep learning,or machine learning in the diagnosis and treatment of any disease published in 2020.We evaluated the methodological quality of the included systematic reviews using“A Measurement tool for the assessment of multiple systematic reviews”(AMSTAR).We also conducted meta-analyses on the diagnostic accuracy of AI on selected disease categories with a large number of included studies and low clinical heterogeneity.Results A total of 40 systematic reviews reporting 1,083 original studies were included,covering 31 diseases from 11 groups of diseases.Eleven systematic reviews were related to neoplasms and nine were systematic reviews related to diseases of the digestive system.We selected digestive system diseases for the meta-analysis.The pooled sensitivities(with 95%confidence interval(CI))of AI to assist the diagnosis of helicobacter pylori,gastrointestinal ulcers,hemorrhage,esophageal tumors,gastric tumors,and intestinal tumors(with 95%CI)were 0.91(0.83-0.95),0.99(0.76-1.00),0.95(0.83-0.99),0.90(0.85-0.93),0.90(0.82-0.95),and 0.93(0.88-0.96),respectively,and the pooled specificities were 0.82(0.77-0.87),0.97(0.86-1.00),1.00(0.99-1.00),0.80(0.71-0.87),0.93(0.87-0.97),and 0.89(0.85-0.92),respectively.The AMSTAR items“the list of included studies”(n=39,97.5%)and“the characteristics of the included studies”(n=39,97.5%)had the highest compliance among the reviews;the compliance was relatively low to the items“the consideration of publication status”(n=1,2.5%),“the consideration of scientific quality”(n=19,47.5%),“data synthesis methods”(n=18,45.0%),and“the evaluation of publication bias”(n=13,32.5%).Conclusions The main subjects of systematic reviews on AI applications in cli

Light perception at dawn plays a key role in coordinating multiple molecular processes and in entraining the plant circadian clock.The Arabidopsis mutant lacking the main photoreceptors,however,still shows clock entrainment,indicating that the integration of light into the morning transcriptome is not well understood.In this study,we performed a high-resolution RNA-sequencing time-series experiment,sampling every 2 min beginning at dawn.In parallel experiments,we perturbed temperature,the circadian clock,photoreceptor signaling,and chloroplast-derived light signaling.We used these data to infer a gene network that describes the gene expression dynamics after light stimulus in the morning,and then validated key edges.By sampling time points at high density,we are able to identify three light-and temperature-sensitive bursts of transcription factor activity,one of which lasts for only about 8 min.Phytochrome and cryptochrome mutants cause a delay in the transcriptional bursts at dawn,and completely remove a burst of expression in key photomorphogenesis genes(HY5 and BBX family).Our complete network is available online(http://www-users.***.ac.uk/∼de656/dawnBurst/dawnBurst.html).Taken together,our results show that phytochrome and cryptochrome signaling is required for fine-tuning the dawn transcriptional response to light,but separate pathways can robustly activate much of the program in their absence.

Acute kidney injury(AKI),characterized by acute renal dysfunction,is an increasingly common clinical problem and an important risk factor in the subsequent development of chronic kidney disease(CKD).Regardless of the initial insults,the progression of CKD after AKI involves multiple types of cells,including renal resident cells and immune cells such as macrophages.Recently,the involvements of macrophages in AKI-to-CKD transition have garnered significant attention.Furthermore,substantial progress has also been made in elucidating the pathophysiological functions of macrophages from the acute kidney to repair or fibrosis.In this review,we highlight current knowledge regarding the roles and mechanisms of macrophage activation and phenotypic polarization,and transdifferentiation in the development of AKI-to-CKD transition.In addition,the potential of macrophage-based therapy for preventing AKI-to-CKD transition is also discussed.
