果蝇振翅鸣声信号特征分析

发声是动物间进行交流的信息方式,声音信号的特征对应于动物的某种行为.以Matlab为工具,对采集到的雌、雄地中海果蝇飞行时振翅产生的声音进行了时域和频域的分析、比较,并提取其声音信号特征参数,即正常飞行鸣声的波形都为正弦波,声音的基频为147Hz,并带有多个谐波,其窄带声谱图具有良好的频率分辨率.研究还表明这种果蝇种内雌雄两性飞行时振翅特征有很大相似性.

论文人画家与戏剧票友对传统中国美学的影响

文人画家是有士大夫气息,高蹈于山林、胸中有气味的中国传统文人精英。文人画家历来鄙视专业画家与画工。戏剧票友视戏剧为修身养性的雅趣,是娱己娱人的享乐方式,其内心视那些专业戏剧演员为“戏子”、“贱业”。文人画家与戏剧票友利用自己话语霸权把他们的审美好恶强加给了绘画和戏剧,并影响了绘画与戏剧艺术的发展,从而造就了文人画家与戏剧票友的美学思想对中国传统美学取向的影响,并一直延续到现在。     

Lipids changes in liver cancer

Liver is one of the most important organs in energy metabolism. Most plasma apolipoproteins and endogenous lipids and lipoproteins are synthesized in the liver. It depends on the integrity of liver cellular function, which ensures homeostasis of lipid and lipoprotein metabolism. When liver cancer occurs, these processes are impaired and the plasma lipid and lipoprotein patterns may be changed. Liver cancer is the fifth common malignant tumor worldwide, and is closely related to the infections of hepatitis B virus （HBV） and hepatitis C virus （HCV）. HBV and HCV infections are quite common in China and other Southeast Asian countries. In addition, liver cancer is often followed by a procession of chronic hepatitis or cirrhosis, so that hepatic function is damaged obviously on these bases, which may significantly influence lipid and lipoprotein metabolism in vivo. In this review we summarize the clinical significance of lipid and lipoprotein metabolism under liver cancer.     

Novel distribution pattern of fibrinolytic components in rabbit tissues extract： a preliminary study

Objective: The purpose of this work was to investigate the distribution pattern of fibrinolytic factors and their inhibitors in rabbit tissues. Methods: The components of the fibrinolytic system in extracts from a variety of rabbit tissues, including tissue plasminogen activator (tPA), plasminogen activator inhibitor-1 (PAI-1), plasminogen (Plg), plasmin (Pl) and α2 plasmin inhibitor (α2PI), were determined by colorimetric assay. Results: The tissue extracts in renal, small intestine, lung, brain and spleen demonstrated strong fibrinolytic function, in which high activity of tPA, Plg and Pl was manifested; whereas in skeletal muscle, tongue and stomach, higher activity of PAI-1 and α2PI showed obviously. Also excellent linear correlations were found between levels of tPA and PAI-1, Pl and α2PI, Plg and Pl. In related tissues, renal cortex and renal marrow showed distinctly higher activity of tPA and lower activity of PAI-1, with the levels of Plg and Pl in renal cortex being higher than those in renal marrow, where the α2PI level was higher than that in renal cortex. Similarly, the levels of tPA, Plg and Pl in small intestine were higher than those in large intestine, but with respect to PAI-1 and α2PI, the matter was reverse. In addition, the fibrinolytic activity in muscle tissue was lower, however, the levels of tPA, Plg, and Pl in cardiac muscle were obviously higher than those in skeletal muscles, and the levels of PAI-1 and α2PI were significantly lower than those in skeletal muscle. Conclusion: Our data demonstrate that a remarkable difference of the fibrinolytic patterns exists in rabbit tissues, which has probable profound significance in understanding the relationship between the function of haemostasis or thrombosis and the physiologic function in tissues.     

刑法没收对象之探讨

我国刑法对没收对象没有作出明确的规定,实践中使用的涉案财产的概念模糊而导致侦查机关任意扩大扣押的范围,易于对当事人财产权利造成侵害。本文在借鉴有关国家和地区的立法经验和理论研究的基础上,提出刑法没收的对象应从犯罪工具、犯罪所得和违禁品以三个方面予以具体化界定,并对三类涉案财物的内涵、外延及其划定时存在的问题进行了探讨。     

语言实验室在大学英语形成性评价中的作用
