对适用于加州帕克菲尔德附近的圣安德烈斯断层上中强地震(m～6)的地震不稳定模型,计算了作为时间和地面位置函数的理论压磁场。不稳定模型对一个32a地震轮回的所有时段模拟断层滑动和应力,其中包括失稳(主震)滑动。当该断层的一个近乎闭锁的断块受周围非地震滑动的作用变得充分承载以致于达到快速破裂的条件时,就会发生主震滑动。使用基于类似于应变核的压磁核的解析法,直接由断层滑动计算了压磁场。在地震间隔期间,闭锁断块上应力集中的增强将伴随着磁异常场的缓慢演变,在临近震中地区导致约±2nT的最大积累变化。主震滑动大约消除地震间隔期间所积累变化的一半,快速震后松驰消除剩余的大部分。地震间隔期间在闭锁断层附近一些测点上,场的变化速率逐渐增加,而另一些测点则逐渐减小。这种效应在主震前最后3～4a最显著,并且在适当选取的一些成对测点上,造成差值场时序趋势反向。如果这样的反向可与其他源所引起的地磁变化相区别的话,那么这种反向将构成临近破裂的前兆指标。

This paper presents a description and performance evaluation of a new bit-level, lossless, adaptive, and asymmetric data compression scheme that is based on the adaptive character wordlength （ACW（n）） algorithm. The proposed scheme enhances the compression ratio of the ACW（n） algorithm by dividing the binary sequence into a number of subsequences （s）, each of them satisfying the condition that the number of decimal values （d） of the n-bit length characters is equal to or less than 256. Therefore, the new scheme is referred to as ACW（n, s）, where n is the adaptive character wordlength and s is the number of subsequences. The new scheme was used to compress a number of text files from standard corpora. The obtained results demonstrate that the ACW（n, s） scheme achieves higher compression ratio than many widely used compression algorithms and it achieves a competitive performance compared to state-of-the-art compression tools.

AIm: To investigate the effects of mammalian target of rapamycin(mT OR) inhibition on liver regeneration and autophagy in a surgical resection ***: C57BL/6 mice were subjected to a 70% partial hepatectomy(PH) and treated intraperitoneally every 24 h with a combination of the m TOR inhibitor rapamycin(2.5 mg/kg per day) and the steroid dexamethasone(2.0 mg/kg per day) in phosphate bufferedsaline(PBS) or with PBS alone as vehicle control. In the immunosuppressant group, part of the group was treated subcutaneously 4 h prior to and 24 h after PH with a combination of human recombinant interleukin 6(IL-6; 500 μg/kg per day) and hepatocyte growth factor(HGF; 100 μg/kg per day) in PBS. Animals were sacrificed 2, 3 or 5 d after PH and liver tissue and blood were collected for further analysis. Immunohistochemical staining for 5-Bromo-2'-deoxyuridine(Brd U) was used to quantify hepatocyte proliferation. Western blotting was used to detect hepatic microtubule-associated protein 1 light chain 3(LC3)-Ⅱ protein expression as a marker for autophagy. Hepatic gene expression levels of proliferation-, inflammation- and angiogenesisrelated genes were examined by real-time reverse transcription-polymerase chain reaction and serum bilirubin and transaminase levels were analyzed at the clinical chemical core facility of the Erasmus mC-University medical ***: m TOR inhibition significantly suppressed regeneration, shown by decreased hepatocyte proliferation(2% vs 12% Brd U positive hepatocyte nuclei at day 2, P more increased serum transaminase levels(aspartate aminotransferase 641 U/L vs 185 U/L at day 2, P = 0.02). Expression of the autophagy marker LC3-Ⅱ, which was reduced during normal liver regeneration, increased after mT OR inhibition(46% increase at day 2, P = 0.04).

Advances in cellular and molecular biology underpin most current therapeutic advances in *** advances for neurological and neurodegenerative diseases are hindered by the lack of similar specimens. It is becoming increasingly evident that greater access to human brain tissue is necessary to understand both the cellular biology of these diseases and their variation. Research in these areas is vital to the development of viable therapeutic options for these currently untreatable diseases. The development and coordination of human brain specimen collection through brain banks is evolving. This perspective article from the Sydney Brain Bank reviews data concerning the best ways to collect and store material for different research purposes.
