Experimental Observables on Nuclear Liquid Gas Phase Transition

Progress on nuclear liquid gas phase transition （LGPT） or critical behavior has been simply reviewed and some signals of LGPT in heavy ion collisions, especially in NIMROD data, are focused. These signals include the power-law charge distribution, the largest fluctuation of the fragment observables, the nuclear Zipf law, caloric curve and critical exponent analysis etc.     

矩阵初等理论在Fibonacci数列研究中的应用

Fibonacci数列是递推关系中的一个典型问题,问题本身虽然是一种假想,然而它的结果却有诸多用途。文章在文献[1]的基础上,进一步地探讨了Fibonacci数列矩阵元素间的关系,证明了当r,m≥5时,矩阵D_(m×r)~4的秩为5。     

论化学武器的危害及其防护

化学武器虽然早已被国际公约禁止,但有些国家并没有放弃研制和生产,国际恐怖组织也在利用化学武器制造恐怖袭击或进行恐怖威胁。因此,充分认识化学武器对人类的危害,做好防护和防范工作具有重要的现实意义。     

Chronobiology of sleep in humans

Periodic circadian (24-h) cycles play an important role in daily hormonal and behavioural rhythms. Usually our sleep/wake cycle, temperature and melatonin rhythms are internally synchronized with a stable phase relationship. When there is a desynchrony between the sleep/wake cycle and circadian rhythm, sleep disorders such as advanced and delayed sleep phase syndrome can arise as well as transient chronobiologic disturbances, for example from jet lag and shift work. Appropriately timed bright light is effective in re-timing the circadian rhythm and sleep pattern to a more desired time, ameliorating these disturbances. Other less potent retiming effects may also be obtained from the judicious use of melatonin and exercise.
