| 1 | Long-term results of endoscopic balloon dilatation of lower gastrointestinal tract strictures in Crohn's disease:A prospective study显示文摘AIM:To examine the long-term results of endoscopic treatment in a prospective study conducted over a period of 10 years,1997 to January 2007.METHODS:A total of 25 patients(20 female and five male:aged 18-75 years),with at least one symptom of stricture not passable with the standard colonoscope and with a confirmed scarred Crohn's stricture of the lower gastrointestinal tract,were included in the study.The main symptom was abdominal pain.The endoscopic balloon dilatation was performed with an 18 mm balloon under endoscopic and radiological control.RESULTS:Eleven strictures were located in the colon,13 at the anastomosis after ileocecal resection,three at the Bauhin valve and four in the ileum.Four patients had two strictures and one patient had three strictures.Of the 31 strictures,in 30 was balloon dilatation successful in a single endoscopic session,so that eventually the strictures could be passed easily with the standard colonoscope.In one patient with a long stricture of the ileum involving the Bauhin valve and an additional stricture of the ileum which were 15 cm apart,sufficient dilatation was not possible.This patient therefore required surgery.Improvement of abdominal symptoms was achieved in all cases which had technically successful balloon dilatation,althoughin one case perforation occurred after dilatation of a recurrent stricture.Available follow-up was in the range of 54-118 mo(mean of 81 mo).The relapse rate over this period was 46%,but 64% of relapsing strictures could be successfully dilated again.Only in four patients was surgery required during this follow-up period.CONCLUSION:We conclude from these initial results that endoscopic balloon dilatation,especially for short strictures in Crohn's disease,can be performed with reliable success.Perforation is a rare complication.It is our opinion that in the long-term,the relapse rate is probably higher than after surgery,but usually a second endoscopic treatment can be performed successfully,leading to a considerable success rate of the endoscopic procedure. | Klaus Stienecker Daniel Gleichmann Ulrike Neumayer H Joachim Glaser Carolin Tonus | 2009 | World Journal of Gastroenterology2009，15，21： | 9 |
| 2 | 圆锥破碎机挤压破碎力建模与衬板磨损预测显示文摘设计并进行了集料挤压破碎力实验,并以此建立较为精确的挤压破碎力求解模型;通过对物料的运动学特征分析和对破碎过程求解,获得破碎腔各区域的压缩比和粒度分布系数及挤压破碎压力;分析了破碎壁表面挤压破碎力的作用形式并求解其分量,实现了对破碎壁表面磨损量的求解.结果表明:所建立的集料挤压破碎力模型的求解结果与实地调研所得结果相符,并实现了对破碎壁表面磨损趋势的预测. | 董钢 范秀敏 NEUMAYER Johannesa | 2011 | 上海交通大学学报2011，45，1： | 5 |
| 3 | Deep neural networks for understanding noisy data applied to physical property extraction in scanning probe microscopy显示文摘The rapid development of spectral-imaging methods in scanning probe,electron,and optical microscopy in the last decade have given rise for large multidimensional datasets.In many cases,the reduction of hyperspectral data to the lower-dimension materialsspecific parameters is based on functional fitting,where an approximate form of the fitting function is known,but the parameters of the function need to be determined.However,functional fits of noisy data realized via iterative methods,such as least-square gradient descent,often yield spurious results and are very sensitive to initial guesses.Here,we demonstrate an approach for the reduction of the hyperspectral data using a deep neural network approach.A combined deep neural network/least-square approach is shown to improve the effective signal-to-noise ratio of band-excitation piezoresponse force microscopy by more than an order of magnitude,allowing characterization when very small driving signals are used or when a material’s response is weak. | Nikolay Borodinov Sabine Neumayer Sergei V.Kalinin Olga S.Ovchinnikova Rama K.Vasudevan Stephen Jesse | 2019 | npj Computational Materials2019，，1： | 3 |
