军队院校群际关系存在的问题及对策

院校群际关系是院校教、管、学三方在日常教育训练活动中形成的相互作用的心理机制与行为模式。和谐的院校群际关系对于提升院校集体凝聚力具有重要的作用。研究表明：当前军队院校群际关系存在一些问题,已经成为影响院校全面建设和可持续发展的重要因素。军队院校要加强文化管理,重视群际沟通,推进群际参与,改善院校群际关系,把院校建设成公平正义、诚信友爱、充满活力、安定有序的和谐军营。     

Atomic packing and short-to-medium range order evolution of Zr-Pd metallic glass

A larger-scale Zr₇₀Pd₃₀ alloy system has been simulated using molecular dynamics (MD) to investigate structure evolution in Zr₇₀Pd₃₀ metallic glass. The simulated pair distribution function of Zr₇₀Pd₃₀ metallic glass agrees well with the experimental results. Voronoi polyhedron analysis indicates that the icosahedra are not randomly distributed in space, but form characteristic intercrossed icosahedral clusters with medium-range order. Intercrossed icosahedral clusters are the dominant local configurations in Zr₇₀Pd₃₀ metallic glass and probably cause the quasicrystalline phase discovered in Zr₇₀Pd₃₀ metallic glass.     

基于数值模拟的语言计算方法

为了描述模糊信息并建立模糊逻辑,研究了基于扩展原理和符号化模型的语言计算方法,提出基于数值模拟的对称分布语言变量表示及计算模型.该模型用特征值和标准方差二维数值反映语言的共性和特性.为了扩大运用范围,针对用任意三角模糊数表示的语言变量,提出基础语言集的寻找方法,以实现语言变量统一,完成模糊语言之间的逻辑运算.在此基础上...     

Mutations in SWI/SNF chromatin remodeling complex gene ARID1B cause Coffin-Siris syndrome

We identified de novo truncating mutations in ARID1B in three individuals with Coffin-Siris syndrome (CSS) by exome sequencing. Array-based copy-number variation (CNV) analysis in 2,000 individuals with intellectual disability revealed deletions encompassing ARID1B in 3 subjects with phenotypes partially overlapping that of CSS. Taken together with published data, these results indicate that haploinsufficiency of the ARID1B gene, which encodes an epigenetic modifier of chromatin structure, is an important cause of CSS and is potentially a common cause of intellectual disability and speech impairment.

Quantum programming: From theories to implementations

This paper surveys the new field of programming methodology and techniques for future quantum computers, including design of sequential and concurrent quantum programming languages, their semantics and implementations. Several verification methods for quantum programs and communication protocols are also reviewed. The potential applications of programming techniques and related formal methods in quantum engineering are pointed out.     

信息化教育下的学习理论及学习模式研究

在信息化教育的背景下,建构主义学习理论较行为主义和认知主义学习理论更能满足学习者的需求。自主学习、探究学习、协作学习三种学习模式也得到广泛应用。教师只有转变教学观念,改进教学策略,不断创新,才能促进信息化环境下学习模式的实现。     

磁性琼酯糖亲和吸附剂的合成与应用

采用反相悬浮包埋技术合成了粒径在43-295μm之间的磁性琼脂糖微球。磁性琼脂糖微球经环氧氯丙烷活化后，分别键合6-氨基已酸、氨基乙酸和乙二胺为间隔臂，用水溶性碳二亚胺为缩合剂，分别偶联对氨基苯甲脒、l-精氨酸甲酯和胍基已酸，制备了3种磁性亲和吸附剂，并用于尿激酶粗品的分离纯化。测定了活性回收率和比活提高倍数，并与以磁性葡聚糖为基质的磁性亲和吸附剂对尿激酶的纯化效果进行了对比。
