Aim: To describe the reproductive outcome following intracytoplasmic sperm injection (ICSI) for male factor infertility associated with Crohn's disease and 6-mercap-topurine (6-MP) chemotherapy. Methods: The male partner of a couple suffered from severe Crohn's disease and received a 3-month course of 6-MP for this condition. Two spontaneous conceptions were established before 6-MP, although post-chemotherapy semen analysis found the sperm concentration to be 8,000/mL. In vitro fertilization (IVF) with ICSI and embryo transfer was performed. Results: The woman underwent an uncomplicated controlled ovarian hyperstimulation sequence using a combined rec-FSH+hMG protocol, following late luteal phase pituitary downregulation. This culminated in the retrieval of 18 oocytes, 11 of which were fertilized with ICSI. She later delivered a normal male infant without urogenital anomaly. Four nontransferred blastocysts were cryopreserved. Conclusion: This report describes the first successful birth after ICSI for severe oligozoospermia associated with Crohn's disease and 6-MP therapy. We outline salient features of Crohn's disease, 6-MP pharmacology, and their relevance to human fertility.

The human visual system is still an important factor in military warfare;military personnel receive training on effective search strategies,and camouflage that can effectively conceal objects and personnel is a key component of a successful integrated survivability *** methods of camouflage assessment have,amongst others,used psychophysics to generate distinctiveness ***,the population from which the human observers are drawn is often not well defined,or necessarily *** this experiment we designed a new platform for testing multiple patterns based on a camouflaged object detection task,and investigate whether trained military observers perform better than *** use a two-alternative forced choice paradigm,with participants searching images of woodland for a replica military helmet displaying Olive Green,Multi Terrain Pattern,US Marine Pattern or,as a conspicuous control,UN Peacekeeper *** data show that there is no difference in detection performance between the two observer groups but that there are clear differences in the effectiveness of the different helmet colour patterns in a temperate woodland *** conclude that when tasks involve very short stimulus presentation times,task-specific training has little effect on the success of target detection and thus this paradigm is particularly suitable for robust estimates of camouflage efficacy.

城市热辐射方向性限制了遥感地表温度反演精度,阻碍了对全球城市气候(如城市地表能量通量估算和城市热环境评估)的准确理解.然而,全球不同气候背景城市热辐射方向性时空特征及其造成的城市地表能量通量和热岛强度遥感估算偏差仍不清楚,在全球尺度是否存在与城市热辐射方向性密切相关且易获取的地表和气候参量尚不明晰.本研究结合多角度卫星观测地表温度和遥感云平台,分析了全球5500多个城市的热辐射方向性特征,量化了其造成的全球城市地表能量通量和热岛强度遥感估算偏差,厘清了全球尺度城市热辐射方向性与关键地表和气候参量的关系.研究发现全球城市平均热辐射方向性强度在夏季白天下午高达5.4 K.在极端情况下,当地表温度观测天顶角位于±60°时,热辐射方向性使得全球城市地表显热通量和热岛强度分别低估45.4%和43.0%.研究进一步发现全球城市热辐射方向性与地表不透水面百分比和空气温度具有良好的统计关系,这为卫星遥感城市地表温度角度纠正提供了新思路.

中国陶瓷艺术的仿古风

作者： Rosemary e.scott 盛洁桦西湖博物馆

从艺术家们对昔日的态度中,我们能够发现东亚与欧洲艺术之间的种种差别。东亚的艺术家要是创造二维或三维作品,就会习惯性地对前代的杰作表现出较大的尊重,并且频繁地从中汲取灵感。艺术家的赞助人往往在古玩方面知识渊博.

信息系统的效能对研究人员和开发人员来说都是十分重要的问题。且不考虑它受关注的广泛程度及其重要用途,“计算机世界”已经毫不费力地评出了一百个信息系统效能等级。本文通过使用同构模型来检验导出“计算机世界”等级的效能度量工具的有效性。目前建议使用的度量工具有两种,一种是反射模型(reflective model),但由这种模型导出的等级及其可靠度值得怀疑,另外,其内容及结构的有效性也有疑点。由于同一结构的多个示性(indicator)必须是同质的(以便将它们集成为一个组合索引),因此在可靠性和有效性上也就容易出现问题。为了解决这一问题,可以将信息系统效能表示为一种多维结构,从而成为因果模型(causal model)的一部分。基于该领域已有的研究成果,本文提出了改进度量工具的建议。
