1Inclusion Modification with Mg Treatment for 35CrNi3MoV Steel显示文摘The effects of Mg on the inclusion characteristics of 35CrNi3MoV steel have been studied. The results show that Mg treatment reduces obviously the amount of inclusion in the steel.Magnesiurn and oxygen in liquid steel form dispersed fine particles of MgO, to which other oxides or sulphides nucleated at heterogeneity and grown during solidification. In this way the inclusions are modified. The small spherical inclusions containing MgO have been observed in the Mg treated steel in contrast to the large angular inclusions with Al2O3 in the conventional steel. Especially the elongated MnS inclusion is replaced by small MgS·MgO or MgS. MnS·MgO complex inclusion. The formation of inclusions have been discussed.Fu, J Yu, YG Wang, AR Chen, BP Sun, WS 1998Journal of Materials Science & Technology1998,14,1:22
2High-performance modified uni-traveling carrier photodiode integrated on a thin-film lithium niobate platform显示文摘Lithium niobate on insulator(LNOI)has become an intriguing platform for integrated photonics for applications in communications,microwave photonics,and computing.Whereas,integrated devices including modulators,resonators,and lasers with high performance have been recently realized on the LNOI platform,high-speed photodetectors,an essential building block in photonic integrated circuits,have not been demonstrated on LNOI yet.Here,we demonstrate for the first time,heterogeneously integrated modified uni-traveling carrier photodiodes on LNOI with a record-high bandwidth of 80 GHz and a responsivity of 0.6 A/W at a 1550-nm wavelength.The photodiodes are based on an n-down In GaAs/InP epitaxial layer structure that was optimized for high carrier transit time-limited bandwidth.Photodiode integration was achieved using a scalable wafer die bonding approach that is fully compatible with the LNOI platform.XIANGWEN GUO LINBO SHAO LINGYAN HE KEVIN LUKE JESSE MORGAN KEYE SUN JUNYI GAO TA-CHING TZU YANG SHEN DEKANG CHEN BINGTIAN GUO FENGXIN YU QIANHUAN YU MASOUD JAFARI MARKO LONčAR MIAN ZHANG ANDREAS BELING 2022Photonics Research2022,10,6:2
3糖尿病、糖尿病前期与亚临床心肌损害发生率显示文摘众所周知,处于糖尿病前期者和糖尿病患者存在较高的心血管事件发生风险。然而,糖尿病前期和糖尿病与亚临床心肌损害发生间的关系尚不明确。方法与结果:应用高敏心肌肌钙蛋白T (highly sensitive cardiac troponin T hs-cTnT)分析,测定社区动脉粥样硬化风险研究中9331例受试者两个时间点(间隔6年)的心肌肌钙蛋白T(cardiac troponin T,cTnT)水平,所有受试者为无糖尿病或处于糖尿病前期,或糖尿病不伴心血管疾病(包括心电图检测出来的无临床症状的心肌梗死)。Selvin E Lazo M Chen Y Shen L Rubin J McEvoy JW Hoogeveen RC Sharrett AR Ballantyne CM Coresh J 刘莉 2014中华高血压杂志2014,22,9:2
