Fractal image compression is a completely new method to compress images by searching and exploiting the self similarity of the whole image . Fractal Block Coding (FBC) is a practicable fractal coding scheme with annoying slow encoding speed . In this paper, we classify the image blocks by Classified Vector Quantization (CVQ) technique and present an Adaptive Block Truncation Coding (ABTC) scheme to process the midrange blocks in the image. By this method , we reduce the encoding time to one forty fifth comparing to ordinary FBC method with little change in compression ratio and a little decreased coded image quality.

为了提高锥角药型罩装药结构的侵彻能力,通过改变其顶部锥角为喇叭形研发了一种新型喇叭-锥角结合药型罩。采用模拟软件ANSYS/LS-DYNA对喇叭-锥角结合药型罩、平顶药型罩、锥角药型罩在爆轰波作用下射流的形成以及对45号钢板的侵彻过程进行数值模拟,并对3种药型罩形成的射流参数如头部速度、射流断裂时间等以及对45号钢板的侵彻性能进行了对比。结果表明,在装药口径为80mm、装药高度为100mm的圆柱和圆锥结合型装药结构的条件下,喇叭-锥角结合药型罩形成的射流头部速度为7 690m/s,比锥角药型罩形成的射流提高约9.54%,对45号钢板的侵彻深度提高约19.82%;比平顶药型罩形成的射流头部速度提高约6.36%,对45号钢板的侵彻深度提高约12.25%。

基于硫自养反硝化工艺研究了火化烟气吸收液的深度脱氮过程与调控技术。通过逐级提高硝态氮负荷的方式可以在30 d内使硝态氮去除率提高至89.0%,石灰石可以有效替代碳酸氢钠为反应系统提供碱度,使自养反硝化菌群稳定发挥脱氮能力。相比于硫酸盐,亚硝态氮表现出更为明显的自养反硝化功能菌群毒性抑制效果,但是在功能菌群适应进水水质后,系统的硝态氮去除率均高于93.2%。定期反冲洗可以防止硫磺填料板结现象的发生,从而使系统维持较好的硝态氮去除效果。Thiobacillus sp.和Sulfrimonas sp.是系统中的优势菌群,相对丰度占总自养脱氮功能菌群的70.5%以上,但是Sulfuricurvum sp.的相对丰度则明显降低,主要原因在于其不能还原亚硝态氮。

Background Gambogic acid is a pure active compound isolated from the traditional Chinese medicinal plant gamboge （Garcinia morella Desv.）. Based on the preliminary results of a phase I study, this phase Ila study compared the efficacy and safety of different dosage schedules of gambogic acid in patients with advanced malignant tumors. Methods Patients with advanced or metastases cancer who had not received any effective routine conventional treatment or who had failed to respond to the existing conventional treatment were randomly assigned to receive either 45 mg/m2 gambogic acid intravenously from Days 1 to 5 of a 2-week cycle （Group A）, or 45 mg/m2 every other day for a total of five times during a 2-week cycle （Group B）. The primary endpoint was objective response rate （ORR）. Results Twenty-one patients assigned to Group A and 26 to Group B were included in the final analysis. The ORRs were 14.3% in Group A and 0% in Group B. It was not possible to analyze the significant difference because one of the values was zero. The disease control rates （DCRs） were 76.2% in Group A and 61.5% in Group B （P=0.0456）. The observed adverse reactions were mostly Grades I and II, and occurred in most patients after administration of the trial drug. There was no significant difference in the incidence of adverse reactions between the two arms. Conclusions The preliminary results of this phase Ila exploratory study suggest that gambogic acid has a favorable safety profile when administered at 45 mg/m2. The DCR was greater in patients receiving gambogic acid on Days 1-5 of a 2-week cycle, but the incidence of adverse reactions was similar irrespective of the administration schedule.

Imaging sentinel lymph nodes （SLN） could provide us with critical information about the progression of a cancerous disease. Real-time high-resolution intrao- perative photoacoustic imaging （PAI） in conjunction with a near-infrared （NIR） probe may offer opportunities for the immediate imaging for direct identification and resection of SLN or collecting tissue samples. In this work a commercially amenable synthetic methodology is revealed for fabricating luminescent carbon nanoparticles with rapid clearance properties. A one-pot ＂green＂ technique is pursued, which involved rapid surface passivation of carbon nanopartides with organic macromolecules （e.g., polysorbate, polyethyleneglycol） in solvent-free conditions. Interestingly, the naked carbon nanoparticles are derived for the first time, from commercial food grade honey. Surface coated particles are markedly smaller （-7 nm） than previously explored particles （gold, single-walled carbon nanotubes, copper） for SLN imaging. The results indicate an exceptionally rapid signal enhancement （-2 min） of the SLN. Owing to their strong optical absorption in the NIR region, tiny size and rapid lymphatic transport, this platform offers great potential for faster resection of SLN and may lower complications caused in axillary investigation by mismarking with dyes or low-resolution imaging techniques.

The central nervous system （CNS） plays a key regulatory role in glucose homeostasis. In particular, the brain is important in initiating and coordinating protective counterregulatory responses when blood glucose levels fall. This may due to the metabolic dependency of the CNS on glucose, and protection of food supply to the brain. In healthy subjects, blood glucose is normally maintained within a relatively narrow range. Hypoglycemia in diabetic patients can increase the risk of complications, such as heart disease and diabetic peripheral neuropathy. The clinical research finds that the use of traditional Chinese medicine （TCM） has a positive effect on the treatment of hypoglycemia. Here the authors reviewed the current understanding of sensing and counterregulatory responses to hypoglycemia, and discuss combining traditional Chinese and Western medicine and the theory of iatrogenic hypoglycemia in diabetes treatment. Furthermore, the authors clarify the feasibility of treating hypoglycemia on the basis of TCM theory and CNS and have an insight on its clinical practice.
