采用基于密度泛函理论的第一性原理计算方法,研究了VA族元素(N、P、As、Sb、Bi)对二维AlN电磁性质的影响.研究发现,VA族元素修饰后,二维AlN的能带结构发生显著劈裂,表明体系转变为磁性材料.同时,导带底部向低能量区域移动,使得二维AlN的吸收阈值从紫外线区域扩展至可见光区域.因此,VA族元素的修饰显著调控了二维AlN的电子结构和磁性,为实现可见光响应的光电子和自旋电子器件提供了新思路和可能性.

2d hierarchical lattices' imperfection sensitivity to missing bars defect

引用

Theoretical & Applied Mechanics Letters 2015年第4期5卷 141-145页

作者： Bo Wang Yunfeng Shi Rui Li Youwei Chen Yihua mo State Key Laboratory of Structural Analysis for Industrial Equipment Department of Engineering Mechanics Dalian University of Technology Beijing Institute of Astronautical Systems Engineering

Commercially available lattices contain various kinds of morphological imperfections which result in great degradation in lattices＇ mechanical properties, therefore, to obtain imperfection insensitive lattice structure is obviously a practical research subject. Hierarchical structure materials were found to be a class of promising anti-defect materials, This paper builds hierarchical lattice by adding soft adhesion to lattice＇s cell edges and numerical results show that its imperfection sensitivity to missing bars is minor compared with the classic lattice. Soft adhesion with appropriate properties reinforce cell edge＇s bending stiffness and thus reduce the bending deformation in lattice caused by missing bars defect, which is confirmed by statistical analysis of normalized node displacements of imperfect lattices under hydrostatic compression and shear loads.

背景抑郁障碍(Mdd)在青少年人群中的发病率逐年增高,非自杀性自伤(NSSI)行为也是其常见的临床表现。有研究结果显示维生素d和血脂水平与Mdd有关,但是其是否与NSSI有关尚不明确。目的比较伴或不伴有NSSI行为青少年Mdd患者的25羟维生素d_(3)[25(OH)d_(3)]和血脂水平,并探索其对NSSI的诊断价值。方法选取2020年10月-2022年3月在安徽医科大学附属巢湖医院精神科和合肥市第四人民医院就诊的青少年Mdd患者129例,参考《精神障碍诊断与统计手册》第5版(dSM-5)中NSSI的诊断标准将其分为NSSI组(77例)和非NSSI组(52例)。采用青少年自杀意念量表(PANSI)、失眠严重指数(ISI)、流调用抑郁量表(CES-d)评估患者的临床症状。采集空腹静脉血,检测样本中25(OH)d_(3)和血脂水平,并进行两两比较。进一步采用多因素Logistic回归分析探究青少年Mdd患者发生NSSI行为的影响因素,并绘制受试者工作特征(ROC)曲线评估25(OH)d_(3)和血脂水平对NSSI行为的诊断价值。结果NSSI组的年龄低于非NSSI组,而PANSI总分、ISI总分、CES-d总分高于非NSSI组(Pd_(3)水平低于非NSSI组,而总胆固醇(TC)、高密度脂蛋白胆固醇(HdL-C)和低密度脂蛋白胆固醇(LdL-C)水平高于非NSSI组(PdL-C(OR=5.695,95%CI=2.422~13.388,Pd_(3)(OR=0.871,95%CI=0.768~0.987,Pdd患者伴有NSSI行为的影响因素。LdL-C和25(OH)d_(3)评估青少年Mdd患者NSSI行为发生风险的ROC曲线下面积(AUC)分别为0.73(95%CI=0.65~0.82,Pmol/L、19.15μg/L;LdL-C联合25(OH)d_(3)水平[ln(p/1-p)=1.364X1-0.143X2-0.161,其中X1、X2分别为LdL-C、25(OH)d_(3)]预测青少年Mdd患者NSSI行为的AUC为0.77(95%CI=0.69~0.85,Pdd患者存在一定水平的25(OH)d_(3)和血脂水平紊乱,且LdL-C联合25(OH)d_(3)水平对评估青少年Mdd患者NSSI行为的发生有一定的参考价值,临床应定期检测其动态变化并对症处理。

An Analytic model of Galactic Winds and Mass Outflows

引用

Chinese Journal of Astronomy and.a.trophysics 2005年第4期5卷 327-346页

作者： Cheng-Gang Shu Hou-Jun mo Shu-de Mao Joint Center for Astrophysics Shanghai Normal University Shanghai 200234 Shanghai Astronomical Observatory Chinese Academy of Sciences Shanghai 200030 Max-Planck-Institut fuer Astrophysik Karl-Schwarzschild-Strasse 1 Postfach 1317 D-85741 Garching Germany Astronomy department University of Massachusetts Amherst MA 01003 USA Jodrell Bank Observatory Univ. of Manchester Macclesfield Cheshire SK11 9DL UK

Galactic winds and mass outflows are observed both in nearby starburst galaxies and in high-redshiff star-forming galaxies. We develop a simple analytic model to understand the observed superwind phenomenon with a discussion of the model uncertainties. Our model is built upon the model of McKee ＆ Ostriker for the interstellar medium. It allows one to predict how properties of a superwind,such as wind velocity and mass outflow rate, are related to properties of its starforming host galaxy, such as size, gas density and star formation rate. The model predicts a threshold of star formation rate density for the generation of observable galactic winds. Galaxies with more concentrated star formation activities produce superwinds with higher velocities. The predicted mass outflow rates are comparable to （or slightly larger than） the corresponding star formation rates. We apply our model to both local starburst galaxies and high-redshift Lyman break galaxies,and find its predictions to be in good.a.reement with current observations. Our model is simple and so can be easily incorporated into numerical simulations and semi-analytical models of galaxy formation.

AIM:To investigate the inhibitory effect of hepatitis C virus internal ribosome entry site (HCV IRES) specific inhibitor RNA(IRNA) on gene expression med.a.ed by HCV IRES in ***:By using G418 screening system, hepatoma cells constitutively expressing IRNA or mutant IRNA (mIRNA) were established.a.d characterized, and HCV replicons containing the 5′ untranslated region (5′UTR) were constructed by using the same method. Cotransfection of pCMVNCRluc containing HCV 5′UTR-Iuc fusion genes and eukaryotic vector of IRNA into human hepatic carcinoma cells (HepG2) was performed.a.d the eukaryotic expression plasmid of IRNA was transfected transiently into HCV replicons, pCMVNCRluc or pCd.a.luc was cotransfected with pSV40-β Gal into IRNA expressing hepatoma cells by using lipofectamine 2000 in vitro. Then the reporting gene expression level was examined.a. 48h after transfection by using a luminometer and the expressing level of HCV C antigen was analysed with a confocal ***: Transient expression of IRES specific IRNA could significantly inhibit the expression of reporter gene and viral antigen med.a.ed by HCV IRES by 50% to 90% in vivo, but mIRNA lost its inhibitory activity completely. The luciferase gene expression med.a.ed by HCV IRES was blocked in the HHCC constitutively expressing IRNA. At 48h after transfection, the expression level of reportor gene descreased by 20%, but cap-dependent luciferase gene expression was not affected. IRNA could inhibit the HCV replicon expression 24h after transfection and the highest inhibitory activity was 80% by 72h, and the inhibitory activity was not increased until 7d.a.ter ***:IRNA can inhibit HCV IRES med.a.ed gene expression in vivo.
