Background: The majority of Veterans Affair(VA) hospitals are in urban areas. We examined whether veterans residing in rural areas have lower mental health service use and poorer mental health ***: Veterans with at least 1 warzone deployment in central and northeastern Pennsylvania were randomly selected for an interview. Mental health status, including posttraumatic stress disorder(PTSD), major depression, alcohol abuse and mental health global severity, were assessed using structured interviews. Psychiatric service use was based on self-reported utilization in the past 12 months. Results were compared between veterans residing in rural and non-rural areas. Data were also analyzed using multivariate logistic regression to minimize the influence by confounding ***: A total of 1730 subjects(55% of the eligible veterans) responded to the survey and 1692 of them had complete geocode information. Those that did not have this information(n=38), were excluded from some analyses. Veterans residing in rural areas were older, more often of the white race, married, and experienced fewer stressful events. In comparison to those residing in non-rural areas, veterans residing in rural areas had lower global mental health severity scores;they also had fewer mental health visits. In multivariate logistic regression, rural residence was associated with lower service use, but not with PTSD, major depression, alcohol abuse, and global mental health severity score after adjusting confounding factors(e.g., age, gender, marital status and education).Conclusions: Rural residence is associated with lower mental health service use, but not with poor mental health in veterans with former warzone deployment, suggesting rural residence is possibly protective.

We describe the first case of sirolimus-induced drug fever in a female liver transplant recipient, with a history of hepatitis C-induced end-stage liver cirrhosis in 1999. In 2005, six years after transplantation, she developed calcineurin inhibitor-induced renal function impairment. Immunosuppression was switched from tacrolimus to sirolimus. Two days after the intake of sirolimus, she developed daily fever spikes, but no infectious focus was found. Antibiotic therapy had no influence on the fever. After fourteen days, sirolimus was switched back to tacrolimus and the fever disappeared. In history, the patient developed ciclosporin-induced generalized seizures eleven days after liver transplantation, followed by the development of a motoric speech disorder. Magnetic resonance imaging (MRI) findings were consistent with leucoencephalopathy, therefore immunosuppressive therapy was changed from ciclosporin to tacrolimus and the neurologic symptoms improved significantly. Our case is the first reported case of sirolimus-induced drug fever. In addition, the patient showed the rare occurrence of ciclosporin-induced leukencephalopathy with seizures.

已采用体波声延迟器件的在晶体上沉积氧化锌压电换能器的成熟工艺来制作微波声-光器件。与粘结薄片压电换能器在高频工作时所遇到的基本困难不同,溅射氧化锌换能器在高频能很好地工作,但却碰到了膜太厚的问题(>10微米)。当频段限制在200兆赫-18千兆赫时,传播纵体波的氧化锌膜能很好地工作。氧化锌换能器的沉积不适用于某些具有高声-光品质因素的材料,如钼酸铅和二氧化碲,但是与铌酸锂、钮酸锂、三氧化钛、铌酸钠钡、熔石英、钇-铝石榴石、水晶和兰宝石配合能很好地工作。用氧化锌换能器能获得宽带宽。用铌酸锂和钽酸锂为声-光材料制作了带宽大于1千兆(3分贝)的声-光器件。其中心频率从2.6-6.5千兆赫。1千兆带宽元件的换能器转换损耗(入射射频信号到声信号的总损耗,包括匹配网络损耗)小于10分贝。在此,介绍几种用于腔倒空器的微波声-光器件(目前已生产)的例子。

地形有时被认为是不随尺度发生变化或是随机的面,然而定性的观测结果却表明它们含有特征空间尺度。我们通过分析从加利福尼亚州北部两个地形高分辨率地形图中提取的二维傅里叶功率谱,定量研究了存在于这两个地区的特征地形空间尺度。发现两处地形的谱能量在大致对应于斜坡长度的频率都迅速衰减,意味着地形在较小的尺度上都相对光滑。功率谱图还显示两处地形均具有准周期的脊-谷构造,从中我们也得到了脊-谷构造波长的精确测量结果。通过该频谱与随机生成的地形面的统计频谱特征的比较,我们发现这种均匀的谷间隔不可能产生在随机面上。除了特征空间尺度的识别外,我们还论述了多种谱分析在地貌学上的潜在应用,包括可用于测量诸如在特定尺度或特定方位上局部起伏等地形属性的滤波技术。
