Spintronics,which employs electrons'spin degree of freedom in data storage and transmision,acts as a promising candidate for next-generation information technology owing to its improved processing speed and reduced power *** seek and design materials with highly spin polarized carriers and find an efficient way to control the spin polarization direction of carriers are critical and urgent to spintronics *** this aspect,the bipolar magnetic semiconductor(BMS)serves as an ideal solution since it can generate currents with 100%spin polarization,and the direction of spin polarization is easily tunable by an external gate voltage,Up to now,there have been lots of BMSs predicted by first-principles calculations,however,most of them are extrinsically induced by chemical or physical modifications,and a generalized scheme for designing BMS materials is stil lacking,This paper is aimed to briefly review the existing BMS materials designed by theoretical simulations,analyze the main obstacles to experimental realization,and put forward suggestions for future development.

BACKGROUND： Some scholars think that hypertension is the major risk factor to cause Binswanger disease （BD）, however, BD is also found in some persons with normal blood pressure, so we presume that some other factors, such as diabetes mellitus, hyperlipemia, coronary heart disease and transient ischemic attacks and so on, might participant in the onset of BD. OBJECTIVE： To comparatively observe the difference in accompanying diseases, transcranial doppler （TCD） performance, blood glucose and blood lipid level between BD patients and healthy subjects who received health examination, and between BD patients with different disease condition. DESIGN ： Case-control analysis SETTING ： Department of Emergency, Qingdao Municipal Hospita PARTICIPANTS： Totally 126 patients with BD, 65 male and 61 female, aged from 67 to 85 years old, who hospitalized in the Medical School Hospital of Qingdao University and Qingdao Municipal People＇s Hospital, were chosen, serving as BD patients group. All the patients met the clinical diagnostic criteria of BD introduced by Bennett et al. Another 126 persons, 65 male and 61 female, aged ranging from 67 to 80 years, who received health examination in the same hospital, were homeochronously chosen, serving as control group. Informed consents were obtained from all the subjects. METHODS ： After being admitted, all the subjects including BD patients and persons who homeochrenously received health examination in the same hospital were given examinations of blood pressure, blood lipid, blood glucose, electrocardiogram （ECG） and TCD. Fifty-seven patients with BD were in the stable period and 69 in the progressive period （Stable period： no local or subcortical function disorder found, and no changes in the range of white matter lesion showed by CT and/or MRI in recent 3 months; Progressive period： with local or subcortical function disorder and increase in the range of white matter lesion showed by CT and/or MRI in recent 3 months）.

Objective To review the studies investigating the increased risk of lung cancer in patients with idiopathic pulmonary fibrosis （IPF）.Data sources Data cited in this review were obtained mainly from PubMed and Medline from 1999 to 2013 and highly regarded older publications were also *** selection We identified,retrieved and reviewed the information on the frequency,risk factors,anatomical features,histological types,clinical manifestations,computed tomography findings and underlying mechanisms of lung cancer in IPF *** The prevalence rates of lung cancer in patients with IPF （4.8％ to 48％） are much higher than patients without IPF （2.0％ to 6.4％）.The risk factors for lung cancer in IPF include smoking,male gender,and *** cancers often occur in the peripheral lung zones where fibrotic changes are *** and squamous cell carcinoma are the most common types of lung cancer in patients with *** features of these patients include peripherally located,ill-defined mass mimicking air-space *** underlying mechanisms of the development of lung cancer in patients with IPF have not been fully understood,but may include the inflammatory response,epithelial injury and/or abnormalities,aberrant fibroblast proliferation,epigenetic and genetic changes,reduced cell-to-cell communication,and activation of specific signaling *** These findings suggest that IPF is associated with increased lung cancer *** is necessary to raise the awareness of lung cancer risk in IPF patients among physicians and patients.

针对遥感图像背景复杂及有监督场景分类算法无法利用无标签数据的问题,提出一种基于生成对抗网络的半监督遥感图像场景分类方法。首先,引入谱归一化残差块代替传统生成对抗网络中的二维卷积,利用残差块的跳跃连接解决梯度消失问题;其次,引入特征融合思想,将浅层特征与深层特征进行融合,从而减少特征损失;最后,在生成对抗网络的判别器中加入结合门控的注意力模块,以增强特征判别能力。在EuroSAT和UC Merced数据集上的实验结果表明,该方法能够有效提取判别力更强的特征,提高半监督分类性能。

通过固相反应法制备了MLnBO_4(M=Ba,Sr,Ca;Ln=La,Nd,Sm,Y;B=(Zn0.5Ti0.5),(Mg_(0.5)Ti_(0.5)))陶瓷粉末,使用X射线衍射仪(XRD)分析其相组成,并结合文献中B位为Ga和Al时的结果,探讨了MLnBO_4中K_2NiF_4型层状钙钛矿结构的稳定性。当M^(2+)和B^(3+)固定时,K_2NiF_4型结构的稳定性随钙钛矿层许容因子t偏离1程度的增加而降低;但当M^(2+)或B^(3+)改变时,两者之间并无直接联系。而考虑M^(2+)、Ln^(3+)、B^(3+)离子半径的对比时,则发现K_2NiF_4型结构均出现在以r(M^(2+))/r(Ln^(3+))=1.1、r(Ln^(3+))/r(B^(3+))=2为中心的一定范围内。因此,用M^(2+)、Ln^(3+)、B^(3+)离子半径的对比衡量MLnBO_4中K_2NiF_4型层状钙钛矿结构的稳定性远较用钙钛矿层的许容因子更可靠,这对于相关材料的设计和开发具有重要意义。

近年来,完美涡旋光束被提出并得到了研究。结合完美涡旋光束和偏振奇异以生成完美偏振奇异光场。将2束正交圆偏振的拓扑荷数不同的完美拉盖尔-高斯光束叠加,得到完美偏振奇异光场,实验结果表明:完美偏振奇异光场的半径比传统的偏振奇异光场半径小得多。此外,研究了不同情形的正交圆偏振的完美拉盖尔-高斯光束与传统拉盖尔-高斯光束的叠加,其叠加光场的偏振态表现各异,并且出现了“准高阶偏振奇异”的现象。完美奇异点的模拟生成拓宽了奇异光学的理论研究范畴。
