利用BETHSY喷嘴和Super-Moby-Dick(SMD)喷嘴临界流试验数据对CATHARE2V2.5程序Rev.6.1和Rev.5两个版本中基本物理关系式模块的闪蒸模型进行了评估。评估结果表明,程序计算结果与试验数据吻合较好。其中,Rev.6.1的预测结果比Rev.5的结果更精确,尤其对于SMD喷嘴试验,Rev.6.1的计算结果与试验数据十分吻合,但对于BETHSY喷嘴试验,Rev.6.1的预测值偏高。然后,利用敏感性分析对闪蒸模型进行了局部改进。

Prior appendectomy and the phenotype and course of Crohn's disease

引用

World Journal of Gastroenterology 2006年第8期12卷 1235-1242页

作者： Jacques Cosnes Philippe Seksik isabelle Nion-Larmurier Laurent Beaugerie Jean-Pierre Gendre Service de Gastroentérologie et Nutrition h■pital St-AntoineParisFrance

AIM： To determine whether prior appendectomy modifies the phenotype and severity of Crohn＇s disease. METHODS： Appendectomy status and smoking habits were specified by direct interview in 2838 patients consecutively seen between 1995 and 2004. Occurrence of complications and therapeutic needs were reviewed retrospectively. Additionally, annual disease activity was assessed prospectively between 1995 and 2004 in patients who had not had ileocecal resection and of a matched control group. RESULTS： Compared to 1770 non-appendectomized patients, appendectomized patients more than 5 years before Crohn＇s disease diagnosis （n=716） were more often females, smokers, with ileal disease. Cox regression showed that prior appendectomy was positively related to the risk of intestinal stricture （adjusted hazard ratio, 1.24; 95% confidence interval, 1.13 to 1.36; P=0.02） and inversely related to the risk of perianal fistulization （adjusted hazard ratio, 0.75; 95% confidence interval, 0.68 to 0.83; P=0.002）. No difference was observed between the two groups regarding the therapeutic needs, except for an increased risk of surgery in appendectomized patients, attributable to the increased prevalence of ileal disease. Between 1995 and 2004, Crohn＇s disease was active during 50% of years in appendectomized patients （1318 out of 2637 patientyears） and 51% in non-appendectomized patients （1454 out of 2841 patient-years; NS）. CONCLUSION： Prior appendectomy is associated with a more proximal disease and has an increased risk of stricture and a lesser risk of anal fistulization. However, the severity of the disease is unaffected.

Spatially engineered nonlinearity in resonant metasurfaces

Spatial engineering of the nonlinear susceptibility χ^((2)) in resonant metasurfaces offers a new degree of freedom in the design of the far-field response of second-harmonic generation(SHG). We demonstrate this by applying electric field poling to lithium niobate(LN) thin films, which inverts the spontaneous polarization and thus the sign of χ^((2)). Metasurfaces fabricated in periodically poled LN films reveal the distinct influence of theχ^((2))-patterning on the spatial distribution of the second harmonic. This work is a first step toward far-field engineering of SHG in metasurfaces with electric field poling.
