通过对工业纯镁以及ZM21合金的性能测试研究了镁合金在可降解生物医学中的应用,讨论了等径角挤压制备超细晶以及温挤压对材料性能的影响。晶粒细化导致合金材料压缩强度明显提高,强烈的初始变形织构导致粗晶镁合金拉伸强度高于压缩。等径角挤压能够减弱织构的影响,使不同合金塑性流变行为获得改变。材料腐蚀性能主要受化学成分、晶粒大小以及先前变形诱导晶格畸变程度的综合影响。等径角挤压细化晶粒、增大晶格缺陷密度在一定程度上制衡了材料的腐蚀性能。同时弥散分布的第二相粒子的增加对于点蚀发展有着积极的作用。

To assess the rate of matrix Gla-protein carboxylation in patients with small intestinal bacterial overgrowth (SIBO) and to decipher its association with subclinical *** with suspected SIBO who presented with a low risk for cardiovascular disease and showed no evidence of atherosclerotic plaques were included in the study. A glucose breath test was performed in order to confirm the diagnosis of SIBO and vascular assessment was carried out by ultrasound examination. Plasma levels of the inactive form of MGP (dephosphorylated-uncarboxylated matrix Gla-protein) were quantified by ELISA and vitamin K2 intake was estimated using a food frequency ***-nine patients were included in the study. SIBO was confirmed in 12/39 (30.8%) patients who also presented with a higher concentration of dephosphorylated-uncarboxylated matrix Gla-protein (9.5 μg/L vs 4.2 μg/L; P = 0.004). Arterial stiffness was elevated in the SIBO group (pulse-wave velocity 10.25 m/s vs 7.68 m/s; P = 0.002) and this phenomenon was observed to correlate linearly with the levels of dephosphorylated-uncarboxylated matrix Gla-protein (β = 0.220, R2 = 0.366, P = 0.03). Carotid intima-media thickness and arterial calcifications were not observed to be significantly elevated as compared to *** is associated with reduced matrix Gla-protein activation as well as arterial stiffening. Both these observations are regarded as important indicators of subclinical atherosclerosis. Hence, screening for SIBO, intestinal decontamination and supplementation with vitamin K2 has the potential to be incorporated into clinical practice as additional preventive measures.

Helicobacter pylori(H. pylori) infection is very common and affects approximately half of the world population. It causes gastric diseases, but some authors have reported an association of H. pylori infection with other systemic manifestations beginning in 1994. The list of potential effects of H. pylori outside the stomach includes a number of extragastric manifestations and we focused on neurological, dermatological, hematologic, ocular, cardiovascular, metabolic, allergic, and hepatobiliary diseases. This review discusses these important reported manifestations that are not related to the gastrointestinal tract.

3-D Networks-on-Chip （NoC） emerge as a potent solution to address both the interconnection and design complexity problems facing future Multiprocessor System-on-Chips （MPSoCs）. Effective run-time mapping on such 3-D NoC-based MPSoCs can be quite challenging, as the arrival order and task graphs of the target applications are typically not known a priori, which can be further complicated by stringent energy requirements for NoC systems. This paper thus presents an energy-aware run-time incremental mapping algorithm （ERIM） for 3-D NoC which can minimize the energy consumption due to the data communications among processor cores, while reducing the fragmentation effect on the incoming applications to be mapped, and simultaneously satisfying the thermal constraints imposed on each incoming application. Specifically, incoming applications are mapped to cuboid tile regions for lower energy consumption of communication and the minimal routing. Fragment tiles due to system fragmentation can be gleaned for better resource utilization. Extensive experiments have been conducted to evaluate the performance of the proposed algorithm ERIM, and the results are compared against the optimal mapping algorithm （branch-and-bound） and two heuristic algorithms （TB and TL）. The experiments show that ERIM outperforms TB and TL methods with significant energy saving （more than 10%）, much reduced average response time, and improved system utilization.

Pancreatic surgery represents one of the most challenging areas in digestive surgery. In recent years, an increasing number of laparoscopic pancreatic procedures have been performed and laparoscopic distal pancreatectomy (LDP) has gained world-wide acceptance because it does not require anastomosis or other reconstruction. To date, English literature reports more than 300 papers focusing on LDP, but only 6% included more than 30 patients. Literature review confirms that LDP is a feasible and safe procedure in patients with benign or low grade malignancies. Decreased blood loss and morbidity, early recovery and shorter hospital stay may be the main advantages. Several concerns still exist for laparoscopic pancreatic adenocarcinoma excision. The individual surgeon determines the technical conduction of LDP, with or without spleen preservation; currently robotic pancreatic surgery has gained diffu- sion. Additional researches are necessary to determine the best technique to improve the procedure results.

对Reynolds应力模型(RSM)在数值模拟热分层流场方面进行了优化,即在Reynolds应力方程和湍动能耗散方程的基础上加入标量通量方程和温度扰动方程,使原来的7方程成为了11方程。优化后的模型可以通过精确计算湍流通量输运方程来求解加热湍流中重要的热浮力项。采用7方程RSM、11方程RSM,并用k-ε湍流模型作为参考,对平板间非稳定热分层流动和模拟池式快堆堆心上方的腔室内受迫对流和热分层之间的混合流动进行数值模拟和比较分析,并将计算结果与现有实验数据相比较。结论是:优化后的11方程RSM比其他的湍流模型更适合于计算各向异性的热分层流动。
