超高压器件界面电荷诱发击穿电压退化的改善

本研究提出了一种创新的P型表面掺杂工程技术,可专门应用于仿真程序时,优化布局中具交互指叉(interdigital)几何图案的器件结构内,不同区域的PN结反向击穿电压退化现象。如:超高压器件的源极中心(Source Center)、漏极中心(Drain Center)、或是平坦区(flat region)。超高压器件的工艺中,PN结反向击穿电压的退化往往归咎于界面陷阱电荷(interface-trapped charge)。而在硅晶圆阶段中,由于封装等级(package level)可靠度测试(reliability test)所带来的热应力,亦可使击穿电压退化与电流拥挤(current crowding)等现象浮现。因此,在优化的过程中,为了保有器件的高击穿电压特性,吾人藉由改变P型表面掺杂的二维几何设计,同时也利用静电放电测试(ESD test),来观察界面陷阱电荷,在器件遭受静电放电攻击后的分布变化。本研究最终针对具备最大长度结构(length structure)的P型表面掺杂,在击穿电压操作范围内,以及静电放电测试中,如何得到更佳的稳定性,作深入探讨。

Objective: Herbal therapies are used by a substantial proportion of persons in the United States, and use of these supplements may be even higher in those with chronic liver disease. The aims of this study were to prospectively determine the proportion of US veterans with chronic hepatitis C that are currently taking vitamins and herbal medications and to evaluate factors associated with use of herbal preparations. Methods: Patients with hepatitis C who were seen in the gastroenterology, infectious disease, and primary care clinics at the VA New York Harbor Healthcare System were invited to participate in this prospective study. For comparison, healthy patients without hepatitis C were enrolled from the primary care clinics at the same medical center. Patients were interviewed by trained research coordinators who obtained detailed demographic and clinical data, as well as information on the use of antioxidants (vitamin C and E),multivitamins, and herbal medications. Results: Use of vitamin C (34.8% vs. 19.6% , P < 0.001), vitamin E (25.8% vs. 13.2% ,P < 0.001), multivitamins (43.6% vs. 28.0% , P < 0.001), and herbal therapies (21.0% vs. 10.4% , P<0.001)was significantly higher in the 500 patients with hepatitis C compared with the 250 healthy controls. The most common herbal medications taken by hepatitis C patients were milk thistle (12.2% ), ginseng(4.6% ), and echinacea (3.0% ). After adjusting for age and gender, multivariate logistic regression identified 12 or more years of education (OR 2.7; 95% CI 1.6-4.3; P < 0.001) and annual income of at least ＄ 20,000 (OR 2.0; 95% CI 1.3-3.2; P= 0.004) as the only significant predictors of herbal medication use in patients with hepatitis C. Conclusions: The use of herbal preparations is prevalent among veterans with chronic hepatitis C, especially those with higher levels of education and higher incomes. Obtaining a detailed medical history and documentation of the use of these supplements is critical to determine the po

Aim: Few retrospective studies have evaluated infants with hypertrophic pyloric stenosis (HPS) for associated urological anomalies. They have led to contradictory conclusions. The aim of this study was to evaluate the incidence of urinary tract anomalies in infants with HPS and to establish the clinical significance of this association. Methods: One hundred and twenty-two infants (100 boys) who underwent pyloromyotomy between 1992 and 2002 were prospectively evaluated. Screening ultrasound (Us) of the urinary tract was performed in 107 infants, while 15 did not attend their ultrasound appointment. Results: Renal ultrasound was abnormal in 4 (4%) of 107 screened patients with HPS. Three patients were found to have mild hydronephrosis and, in one patient, a small, normal kidney was detected. Two patients with hydronephrosis had Us follow-up and the third patient underwent Tc-99 mercaptoacetyl triglycine (MAG 3) scan. In all three patients, the hydronephrosis resolved completely on follow-up scan. Conclusion: The incidence of abnormal renal ultrasound in children with HPS is similar to the reported incidence of 3-6%determined with routine ultrasound screening of healthy newborns. The abnormalities detected were not clinically relevant and did not require surgical intervention. We do not recommend screening of the urinary tract in infants with HPS.

The clinical diagnosis of a patient with the phenotype of EhlersDanlos syndrome type VI was confirmed biochemically by the severely diminished level of lysyl hydroxylase (LH) activity in the patient’s skin fibroblasts. A novel homozygous mutation, a single base change of T1360 →G in exon 13 of the LH1 gene, predicted to result in W446G, was identified in the patient’s full-length cDNA. This was confirmed in genomic DNA from both the patient and her parents, who were heterozygous for the mutation. This mutation was introduced into an LH1-pAcGP67 baculoviral construct and expressed, in parallel with normal LH1, in an insect cell system. The loss of LH activity in the mutated recombinant construct confirmed the pathogenicity of this mutation. Although not in the major catalytic site, this mutation occurs in a highly conserved region of the LH1 gene and may contribute to loss of activity by interfering with normal folding of the enzyme.

严格控制由刺盘孢属(Colletotrichum spp.)真菌引起的炭疽病对减少热带水果工业的经济损失十分重要。本文主要研究了阿拉伯胶(GA)(10%)、柠檬香草精油(LG)(0.05%)、肉桂精油(CM)(0.4%)及其复合组分在试验条件下对离体与活体香蕉和番木瓜炭疽病菌的抑制活性。结果表明,0.05%的LG和0.4%的CM对于引起香蕉和番木瓜炭疽病的两种病原菌Colletotrichum musae和Colletotrichum gloeosporioides分别具有抑制活性;单独GA处理并未表现出抑菌活性,但将0.05%LG、0.4%CM与10%GA混合处理则具有较大的抑菌活性;在各处理中,以PDA培养基中加入10%GA及0.4%CM的处理对***和***这两种病原菌抑制活性最显著,对于两种病原菌菌丝生长抑制率分别为73.4%和70.0%,对孢子萌发抑制率分别为88%和85%。活体试验结果也表明,10%GA结合0.4%的CM处理具有最佳的作用效果,对***和***的抑制方面表现出较强的增效作用,对人工接种的香蕉和番木瓜炭疽病导致的腐烂抑制率分别为80%和71%。品质评价的试验结果也表明,10%GA结合0.4%CM的涂膜处理具有良好效果,果实失重率、硬度、可溶性固形物和可滴定酸含量的变化均表明该处理可显著推迟果实的成熟。上述结果表明,10%阿拉伯胶结合0.4%肉桂精油处理可以作为控制诸如香蕉和番木瓜等常见热带水果采后炭疽病的生物杀菌剂。
