Current status and future prospects of stem cell therapy in Alzheimer’s disease

Neural Regeneration Research 2020年第2期15卷 242-250页

Alzheimer’s disease is a common progressive neurodegenerative disorder, pathologically characterized by the presence of β-amyloid plaques and neurofibrillary tangles. Current treatment approaches using drugs only alleviate the symptoms without curing the disease, which is a serious issue and influences the quality of life of the patients and their caregivers. In recent years, stem cell technology has provided new insights into the treatment of neurodegenerative diseases, including Alzheimer’s disease, Parkinson’s disease, and amyotrophic lateral sclerosis. Currently, the main sources of stem cells include neural stem cells, embryonic stem cells, mesenchymal stem cells, and induced pluripotent stem cells. In this review, we discuss the pathophysiology and general treatment of Alzheimer’s disease, and the current state of stem cell transplantation in the treatment of Alzheimer’s disease. We also assess future challenges in the clinical application and drug development of stem cell transplantation as a treatment for Alzheimer’s disease.

Method for Evaluating Digital Video Electromagnetic Information Leakage from Video Cable

引用

Chinese Journal of Electronics 2021年第5期30卷 978-985页

作者： WANG Sen QIU Yang tian jin AECC Aero Engine Control System Institute Electromagnetic Compatibility Laboratory Xidian University

Electromagnetic emissions from electrical information equipment may contain useful information and lead to information leakage. In order to detect the electromagnetic information leakage of digital video cable,a rapid testing method for computer video information leakage detection without reconstructing the displayed image is proposed. In this method, the electromagnetic radiation spectrum of typical image transmitted by HDMI cable is simulated. Then the electromagnetic radiation spectrum of the computer when transmitting the same image as the typical image is obtained by conduction and radiation EMC test methods. Finally, the correlation between the spectrum of simulation and the test spectrum is analyzed, and the correlation coefficient is used to judge whether the computer has produced the electromagnetic leakage of video information. The analysis and test results show that when the correlation coefficient is greater than 0.5, the electromagnetic leakage of computer video information can be judged.

公法域外适用衍生于国际体系的结构性演变,有着经济全球化下独特的政治、经济与意识形态背景。其在公法域外适用需求的显现、国家主权观念的转换、公法禁忌原则的突破以及法律形式的嬗变上,具备了一定的存在基础。但是近年来,囿于美国国际法理念的转变,其由原先对严格属地主义的固守转为对国家利益至上的推崇,因而在公法域外适用上愈发地恣意与专断,使公法域外适用存在严重的法律、外交和道德张力。为应对美国公法域外适用,中国须秉承防御与建设共进的思路。一方面,加强国际合作共同抗衡美国公法域外适用制度的滥用,同时健全中国的反制法律体系;另一方面,梳理总结美国多年来在公法域外适用过程中形成的丰富经验,在此基础上构建完善符合国际法基本原则的中国法域外适用制度。

Multi-Matching Nested languages

引用

Chinese Journal of Electronics 2022年第1期31卷 137-145页

作者： LIU jin DUAN Zhenhua tian Cong ICTT and ISN Laboratory Xidian University

The data with both a linear ordering and a hierarchically nested one-to-one matching of items is ubiquitous, including parenthesis matching languages and hypertext markup language/extensive markup language(HTML/XML) documents. There exist some real-world problems which are beyond one-to-one matching. They have a multi-matching structure including one-to-n or nto-one matching relation. Multiple threads can simultaneously read the same file, one block of memory can be referenced by multiple pointers in programs. We propose a new model of multi-matching nested relations consisting of a sequence of linearly ordered call, return and internal positions and augmented with one-to-one, one-to-n or nto-one matching nested edges from calls to returns. Via linear encoding by introducing tagged letters, multimatching nested words are obtained over a tagged alphabet. We put forward multi-matching nested traceable automata and the accepted languages are called multimatching nested languages. Multi-matching nested grammars are presented which have the same expressive power as the proposed automata. An application is displayed to illustrate how the automata work.

关键词： multimatching nested traceable automata hypermedia markup languages multimatching nested relations multimatching nested languages multimatching structure computational complexity multimatching nested words grammars linear ordering parenthesis matching languages multiple pointers matching nested edges internal positions accepted languages multiple threads multimatching nested grammars XML matching relation via linear encoding

以往学界多认为辽朝详稳源于突厥语“sangun”,为将军之意。本文通过考证详稳与相温、相公、将军等概念的异同,认为辽朝详稳一词源自汉语“相”,“稳”是指契丹语语法中修饰“详”字的附加成分。辽朝详稳官职来源于突厥、回鹘、吐蕃等边疆民族之“相”制,又在“会同改制”过程中脱离其原义,遂成为一种特殊的部族官职。
