2Al matrix composites fabricated by solid-state cold spray deposition:A critical review显示文摘Cold spraying(CS),or cold gas dynamic spray(CGDS),is an emerging solid-state powder deposition process,allowing fast and mass production and restoration of metallic components.CS of metal matrix composites(MMCs)has attracted increasing attention from academia and industry over the last decades,especially in the area of Al matrix composites(AMCs),which have demonstrated a high potential for applications in aerospace,automotive,and electronics industries.This article aims to summarize the recent development of CS-processed AMCs in terms of composite powder preparation,deposition processing,microstructure evolution,mechanical and corrosion properties.Furthermore,this review also reports the relevant research progress with the focus on post-treatments of the AMCs for CS additive manufacturing applications including heat treatment,hot rolling,and friction stir processing.Finally,the challenges and perspectives on the fabrication of advanced AMCs by CS are addressed.Xinliang Xie Shuo Yin Rija-nirina Raoelison Chaoyue Chen Christophe Verdy Wenya Li Gang ji Zhongming Ren Hanlin Liao 2021Journal of Materials Science & Technology2021,,27:8
3面向并行文件系统的性能评估及相对预测模型显示文摘基于Lustre文件系统,对并行文件系统的性能评估和性能建模进行了研究.通过对性能因子的调研,进行了一系列性能评估实验,并提出性能相关性模~(PRModel).在实验评估和PRModel分析中发现,在不同的性能因子之间存在着紧密的性能相关性,为了挖掘并利用这种相关性信息,提出了一种相对性能预测模(RPPModel)来预测不同性能因子条件下的性能.为了验证RPPModel的有效性,设计了大量实验用例.结果表明,预测结果的平均相对误差能够控制在170/o---28%的范围内,易于使用且具有较好的预测准确度.赵铁柱 董守斌 Verdi MARCH Simon SEE 2011软件学报2011,22,9:7
4基于机器学习的并行文件系统性能预测显示文摘并行文件系统能有效解决高性能计算系统的海量数据存储和I/O瓶颈问题.由于影响系统性能的因素十分复杂,如何有效地评估系统性能并对性能进行预测成为一个潜在的挑战和热点.以并行文件系统的性能评估和预测作为研究目标,在研究文件系统的架构和性能因子后,设计了一个基于机器学习的并行文件系统预测模型,运用特征选择算法对性能因子数量进行约简,挖掘出系统性能和影响因子之间的特定的关系进行性能预测.通过设计大量实验用例,对特定的Lustre文件系统进行性能评估和预测.评估和实验结果表明:threads/OST、对象存储器(OSS)的数量、磁盘数目和RAID的组织方式是4个调整系统性能最重要因子,预测结果的平均相对误差能控制在25.1%~32.1%之间,具有较好预准确度.赵铁柱 董守斌 董守斌 Verdi March Simon See 2011计算机研究与发展2011,48,7:5
5Thermal transport and phase transitions of zirconia by on-the-fly machine-learned interatomic potentials显示文摘Machine-learned interatomic potentials enable realistic finite temperature calculations of complex materials properties with firstprinciples accuracy.It is not yet clear,however,how accurately they describe anharmonic properties,which are crucial for predicting the lattice thermal conductivity and phase transitions in solids and,thus,shape their technological applications.Here we employ a recently developed on-the-fly learning technique based on molecular dynamics and Bayesian inference in order to generate an interatomic potential capable to describe the thermodynamic properties of zirconia,an important transition metal oxide.This machine-learned potential accurately captures the temperature-induced phase transitions below the melting point.We further showcase the predictive power of the potential by calculating the heat transport on the basis of Green–Kubo theory,which allows to account for anharmonic effects to all orders.This study indicates that machine-learned potentials trained on the fly offer a routine solution for accurate and efficient simulations of the thermodynamic properties of a vast class of anharmonic materials.Carla Verdi Ferenc Karsai Peitao Liu Ryosuke Jinnouchi Georg Kresse 2021npj Computational Materials2021,,1:5
6Synthesis and characterization of boron-doped NiO thin films pro-duced by spray pyrolysis显示文摘Boron-doped NiO thin flms were prepared on glass substrates at 400 C by airbrush spraying method using a solution of nickel nitrate hexahydrate.Their physical properties were investigated as a function of dopant concentration.From X-ray difraction patterns,it is observed that the flms have cubic structure with lattice parameters varying with boron concentration.The morphologies of the flms were examined by using scanning electron microscopy,and the grain sizes were measured to be around 30-50 nm.Optical measurements show that the band gap energies of the flms frst decrease then increase with increasing boron concentration.The resistivities of the flms were determined by four point probe method,and the changes in resistivity with boron concentration were investigated.U.Alver H.Yayka sh S.Kerli A.Tanr verdi 2013International Journal of Minerals,Metallurgy and Materials2013,20,11:3
7Citalopram increases the differentiation efficacy of bone marrow mesenchymal stem cells into neuronal-like cells显示文摘Several studies have demonstrated that selective serotonin reuptake inhibitor antidepressants can promote neuronal cell proliferation and enhance neuroplasticity both in vitro and in vivo. It is hypothesized that citalopram, a selective serotonin reuptake inhibitor, can promote the neuronal differentiation of adult bone marrow mesenchymal stem cells. Citalopram strongly enhanced neuronal characteristics of the cells derived from bone marrow mesenchymal stem cells. The rate of cell death was decreased in citalopram-treated bone marrow mesenchymal stem cells than in control cells in neurobasal medium. In addition, the cumulative population doubling level of the citalopram-treated cells was significantly increased compared to that of control cells. Also BrdU incorporation was elevated in citalopram-treated cells. These findings suggest that citalopram can improve the neuronal-like cell differentiation of bone marrow mesenchymal stem cells by increasing cell proliferation and survival while maintaining their neuronal characteristics.Javad Verdi Seyed Abdolreza Mortazavi-Tabatabaei Shiva Sharif Hadi Verdi Alireza Shoae-Hassani 2014Neural Regeneration Research2014,9,8:2
8COVID-19:Gastrointestinal manifestations,liver injury and recommendations显示文摘Coronavirus disease 2019(COVID-19)has caused a pandemic that affected all countries with nearly 270 million patients and 5 million deaths,as of as of December,2021.The severe acute respiratory syndrome coronavirus 2 virus targets the receptor,angiotensin-converting enzyme 2,which is frequently found in human intestinal epithelial cells,bile duct epithelial cells,and liver cells,and all gastrointestinal system organs are affected by COVID-19 infection.The aim of this study is to review the gastrointestinal manifestations and liver damage of COVID-19 infection and investigate the severe COVID-19 infection risk in patients that have chronic gastrointestinal disease,along with current treatment guidelines.A literature search was conducted on electronic databases of PubMed,Scopus,and Cochran Library,consisting of COVID-19,liver injury,gastrointestinal system findings,and treatment.Liver and intestinal involvements are the most common manifestations.Diarrhea,anorexia,nausea/vomiting,abdominal pain are the most frequent symptoms seen in intestinal involvement.Mild hepatitis occurs with elevated levels of transaminases.Gastrointestinal involvement is associated with long hospital stay,severity of the disease,and intensive care unit necessity.Treatments and follow-up of patients with inflammatory bowel diseases,cirrhosis,hepatocellular carcinoma,or liver transplant have been negatively affected during the pandemic.Patients with cirrhosis,hepatocellular carcinoma,auto-immune diseases,or liver transplantation may have a greater risk for severe COVID-19.Diagnostic or therapeutic procedures should be restricted with specific conditions.Telemedicine should be used in non-urgent periodic patient follow up.COVID-19 treatment should not be delayed in patients at the risk group.COVID-19 vaccination should be prioritized in this group.Zulal Ozkurt EsraÇınar Tanrıverdi 2022World Journal of Clinical Cases2022,10,4:2
