| 1 | Technological Exploration of RRAM Crossbar Array for Matrix-Vector Multiplication显示文摘矩阵向量增加是为许多计算地集中的算法的关键操作。抵抗切换的随机的存取存储器(RRAM ) 设备和 RRAM 闩穿的新兴的金属氧化物表明了模拟矩阵向量增加的一条有希望的硬件认识与超离频精力效率。在这篇论文,我们分析设备水平和电路水平的影响非理想的因素包括 RRAM 设备的非线性的当前电压的关系,设备制造的变化并且给操作,和 interconnect 抵抗以及另外的闩数组写参数。在那上,我们建议工艺的探索流动让设备参数配置克服非理想的因素的影响并且为各特定的申请在性能,精力,和可靠性之中完成一宗更好的交易。我们向量机器(SVM ) 和混合公民标准和技术(MNIST ) 模式识别数据集开创的支持的模拟结果证明那个 RRAM 闩数组基于 SVM 是柔韧的输入信号变化但是对通道差距偏差敏感。进一步的抵抗决定测试一台 6 位的 RRAM 设备对有能力的礼品在 90% 附近认识到识别精确性,显示 RRAM 闩数组的物理可行性基于 SVM。另外,建议工艺的探索流动能与以前的工作相比在 MNIST 数据集和 26.4% 精力积蓄上完成识别精确性的 10.98% 改进。试验性的结果也证明节省的超过 84.4% 力量能以很少精确性减小的成本被完成。 | Lixue Xia Peng Gu Boxun Li Tianqi Tang Xiling Yin Wenqin Huangfu Shimeng Yu Yu Cao Yu Wang Huazhong Yang | 2016 | Journal of Computer Science & Technology2016，31，1： | 2 |
| 2 | Use of angiotensin-converting enzyme inhibitors and angiotensin Ⅱ receptor blockers in context of COVID-19 outbreak:a retrospective analysis显示文摘The possible effects of angiotensin-converting enzyme inhibitors(ACEIs)or angiotensin Ⅱ receptor blockers(ARBs)on COVID-19 disease severity have generated considerable debate.We performed a single-center,retrospective analysis of hospitalized adult COVID-19 patients in Wuhan,China,who had definite clinical outcome(dead or discharged)by February 15,2020.Patients on anti-hypertensive treatment with or without ACEI/ARB were compared on their clinical characteristics and outcomes.The medical records from 702 patients were screened.Among the 101 patients with a history of hypertension and taking at least one anti-hypertensive medication,40 patients were receiving ACEI/ARB as part of their regimen,and 61 patients were on antihypertensive medication other than ACEI/ARB.We observed no statistically significant differences in percentages of in-hospital mortality(28%vs.34%,P=0.46),ICU admission(20%vs.28%,P=0.37)or invasive mechanical ventilation(18%vs.26%,P=0.31)between patients with or without ACEI/ARB treatment.Further multivariable adjustment of age and gender did not provide evidence for a significant association between ACEI/ARB treatment and severe COVID-19 outcomes.Our findings confirm the lack of an association between chronic receipt of reninangiotensin system antagonists and severe outcomes of COVID-19.Patients should continue previous antihypertensive therapy until further evidence is available. | Jiuyang Xu Chaolin Huang Guohui Fan Zhibo Liu Lianhan Shang Fei Zhou Yeming Wang Jiapei Yu Luning Yang Ke Xie Zhisheng Huang Lixue Huang Xiaoying Gu Hui Li Yi Zhang Yimin Wang Frederick G.Hayden Peter W.Horby Bin Cao Chen Wang | 2020 | Frontiers of Medicine2020，14，5： | 2 |

| 4 | Impact of corticosteroids on initiation and half-year durability of humoral response in COVID-19 survivors显示文摘Background:The impact of corticosteroids on humoral responses in coronavirus disease 2019(COVID-19)sur-vivors during the acute phase and subsequent 6-month period remains unknown.This study aimed to determine how the use of corticosteroids influences the initiation and duration of humoral responses in COVID-19 survivors 6 months after infection onset.Methods:We used kinetic antibody data from the lopinavir-ritonavir trial conducted at Jin Yin-Tan Hospital in January 2020,which involved adults hospitalized with severe COVID-19(LOTUS,ChiCTR2000029308).Anti-body samples were collected from 192 patients during hospitalization,and kinetic antibodies were monitored at all available time points after recruitment.Additionally,plasma samples were collected from 101 COVID-19 survivors for comprehensive humoral immune measurement at the half-year follow-up visit.The main focus was comparing the humoral responses between patients treated with systemic corticosteroid therapy and the non-corticosteroid group.Results:From illness onset to day 30,the median antibody titre areas under the receiver operating characteristic curve(AUCs)of nucleoprotein(N),spike protein(S),and receptor-binding domain(RBD)immunoglobulin G(IgG)were significantly lower in the corticosteroids group.The AUCs of N-,S-,and RBD-IgM as well as neutralizing antibodies(NAbs)were numerically lower in the corticosteroids group compared with the non-corticosteroid group.However,peak titres of N,S,RBD-IgM and-IgG and NAbs were not influenced by corticosteroids.During 6-month follow-up,we observed a delayed decline for most binding antibodies,except N-IgM(��−0.05,95%CI[−0.10,0.00])in the corticosteroids group,though not reaching statistical significance.No significant difference was observed for NAbs.However,for the half-year seropositive rate,corticosteroids significantly accelerated the decay of IgA and IgM but made no difference to N-,S-,and RBD-IgG or NAbs.Additionally,corticosteroids group showed a trend towards delayed viral clearance compared with the non-corticosteroid group,but the results were not statistically significant(adjusted hazard ratio 0.71,95%CI 0.50-1.00;P=0.0508).Conclusion:Our findings suggested that corticosteroid therapy was associated with impaired initiation of the antibody response but this did not compromise the peak titres of binding and neutralizing antibodies.Throughout the decay phase,from the acute phase to the half-year follow-up visit,short-term and low-dose corticosteroids did not significantly affect humoral responses,except for accelerating the waning of short-lived antibodies. | Yeming Wang Li Guo Guohui Fan Yang Han Qiao Zhang Lili Ren Hui Zhang Geng Wang Xueyang Zhang Tingxuan Huang Weiyang Wang Lan Chen Lixue Huang Xiaoying Gu Xinming Wang Jingchuan Zhong Ying Wang Hui Li Jiapei Yu Zhibo Liu Chaolin Huang Bin Cao Jianwei Wang | 2024 | Chinese Medical Journal Pulmonary and Critical Care Medicine2024，2，1： | 0 |
| 5 | Juvenile cardiomyopathy with dystrophin deficiency显示文摘Pseudohypertrophic muscular dystrophy is a lethal X-linked recessive neuromuscular disorder caused by mutations in the dystrophin gene.This gene encodes a cytoskeletal protein that is extensively expressed in muscle cells and that enables the strength,stability,and functionality of myofibers.Muscular dystrophy can be grouped into two different categories based on the mutational rate and clinical severity,Duchenne muscular dystrophy(DMD)and Becker muscular dystrophy(BMD).DMD is the most common and the more severe type of dystrophy.DMD patients usually become wheelchair-bound by the age of 12 years and die in their late teens to early twenties.^(1)In contrast,BMD is relatively less severe and the patients can potentially have alonger lifeexpectancy. | Yuhui Luo Qinglan Shu Yi Wang Min Gu Hao Zhang Siqi Hong Rui Wang Lixue Yin | 2024 | Genes & Diseases2024，11，3： | 0 |
