1Transcutaneous perianal sonography:A sensitive method for the detection of perianal inflammatory lesions in Crohn's disease显示文摘AIM: Pelvic magnetic resonance imaging (MRI) and endoanalultrasound which are established imaging methods forperianal inflammatory lesions in patients with Crohn'sdisease require expensive specialized equipments andexpertise. We investigated the feasibility and sensitivity oftranscutaneous perianal ultrasound (PAUS) using regularultrasound probes in the imaging of perianal inflammatorylesions. The sonographic findings were correlated to pelvicMRI-scans.METHODS: We performed PAUS in 25 patients with Crohn'sdisease and clinical signs of perianal inflammatory disease.VCChin a median of 10 d (range 0-75) these patients underwentMRI of the pelvis. Regular convex and linear high resolutionprobes were used for PAUS. The sonographic findings werecorrelated to the MRI findings by blinded investigators.RESULTS: The sonographic investigations were welltolerated by all patients. Fistulae typically presented ashypoechoic tracks. Twenty-nine fistulae were detected in22 patients. Abscesses were detected in 7 patients andpresented as hypo- or anechoic formations. Twenty-six of29 fistulae and 6 of 7 abscesses could be confirmed byMRI. Kappa statistics showed an excellent agreement(kappa>0.83) between the two imaging methods.CONCLUSION: PAUS is a simple, painless, feasible, real-time method that can be performed without specific patientpreparation which is comparable in its sensitivity to pelvicMRI in the detection of perianal fistulae and/or abscesses.PAUS can especially be recommended as a screening toolin acute perianal disorders such as perianal abscess andfor follow-up studies of perianal inflammatory disease.Jochen Wedemeyer Timm Kirchhoff Gernot Sellge Oliver Bachmann Joachim Lotz Michael Galanski Michael P.Manns Michael J.Gebel Jrg S.Bleck 2004World Journal of Gastroenterology2004,10,19:8
2User-Level Device Drivers: Achieved Performance显示文摘Running device drivers as unprivileged user-level code, encapsulated into their own process, has often been proposed as a technique for increasing system robustness. However, in the past, systems based on user-level drivers have generally exhibited poor I/O performance. Consequently, user-level device drivers have never caught on to any significant degree. In this paper we demonstrate that it is possible to build systems which employ user-level device drivers, without significant performance degradation, even for high-bandwidth devices such as Gigabit Ethernet.Ben Leslie Peter Chubb Nicholas Fitzroy-Dale Stefan Gotz Charles Gray Luke Macpherson Daniel Potts Yue-Ting Shen Kevin Elphinstone Gernot Heiser 2005Journal of Computer Science & Technology2005,20,5:7
3长大桥梁工程的先进节段预制技术及其应用显示文摘桥梁,作为基础设施的核心部分之一,在高速铁路、高速公路、城市地铁或轻轨国家交通网络的发展中扮演了重要角色。在中国高速铁路、高速公路或客运专线交通基础设计建设中,桥梁的设计和施工经常成为决定性因素。在过去的几十年中,桥梁设计者和建造者把节段预制技术(例如,小节段混凝土精确预制、大尺寸混凝土预制和大尺度钢结构预制)推进到了一个新高度,为交通领域的决策者提供了坚实的技术平台。本文简要介绍了这种先进的预制节段技术及其在世界范围内的著名应用范例。John J. Sun Gernot Komar 2009公路2009,54,5:6
4Contribution to the taxonomy of the genus Lycodon H.Boie in Fitzinger,1827(Reptilia:Squamata:Colubridae)in China,with description of two new species and resurrection and elevation of Dinodon septentrionale chapaense Angel,Bourret,1933显示文摘While considerable progress has been made in the taxonomic studies of the genus Lycodon in Asia,questions remain to be clarified regarding the taxonomy of certain groups,particularly those containing species in China.Not only do many regions in China remain overlooked by herpetologists,resulting in the possibility of undiscovered new species,but the surveyed areas also have suspicious records of recognized congeners that require taxonomic confirmations.Combining both morphological and genetic data,we tackle these outstanding issues in the taxonomy of Lycodon in China.In particular,we discover two new species of Lycodon:one from the previously neglected hot-dry valley in the northern Hengduan Mountain Region close to Tibet,and another recluse and cryptic species from the L.fasciatus complex in the downtown park of a major city in southern Sichuan Province.Additionally,we clarify the distribution of L.septentrionalis in China and resurrect and elevate its junior synonym subspecies,Dinodon septentrionale chapaense,as a full,valid species,and we synonymize the recently described L.namdongensis to the resurrected L.chapaensis comb.nov..Lycodon chapaensis comb.nov.thus represents a new national record of reptilian fauna of China.Lastly,based on literature review,we also correct some of the erroneous records of L.fasciatus and L.ruhstrati in China,point out remaining taxonomic issues of the genus for future research,and update the dichotomous key and distribution of the 20 species of Lycodon currently recorded from China.Kai Wang Zhong-Bin Yu Gernot Vogel Jing Che 2021Zoological Research2021,42,1:5
5Multilocus Phylogeny of Lycodon and the Taxonomic Revision of Oligodon multizonatum显示文摘Classification of the Asian snake genera Lycodon and Oligodon has proven challenging. We conducted a molecular phylogenetic analysis to estimate the phylogenetic relationships in the genus of Lycodon and clarify the taxonomic status of Oligodon multizonatum using mitochondrial(cyt b, ND4) and nuclear(c-mos) genes. Phylogenetic trees estimated using Maximum Likelihood and Bayesian Inference indicated that O. multizonatum is actually a species of Lycodon. Comparing morphological data from O. multizonatum and its closest relatives also supported this conclusion. Our results imply that a thorough review of the evolutionary relationships in the genus of Lycodon is strong suggested.Juan LEI Xiaoyu SUN Ke JIANG Gernot VOGEL David T.BOOTH Li DING 2014Asian Herpetological Research2014,5,1:3

7Quest for the best endoscopic imaging modality for computer-assisted colonic polyp staging显示文摘BACKGROUND It was shown in previous studies that high definition endoscopy, high magnification endoscopy and image enhancement technologies, such as chromoendoscopy and digital chromoendoscopy [narrow-band imaging(NBI), iScan] facilitate the detection and classification of colonic polyps during endoscopic sessions. However, there are no comprehensive studies so far that analyze which endoscopic imaging modalities facilitate the automated classification of colonic polyps. In this work, we investigate the impact of endoscopic imaging modalities on the results of computer-assisted diagnosis systems for colonic polyp staging.AIM To assess which endoscopic imaging modalities are best suited for the computerassisted staging of colonic polyps.METHODS In our experiments, we apply twelve state-of-the-art feature extraction methods for the classification of colonic polyps to five endoscopic image databases of colonic lesions. For this purpose, we employ a specifically designed experimental setup to avoid biases in the outcomes caused by differing numbers of images per image database. The image databases were obtained using different imaging modalities. Two databases were obtained by high-definition endoscopy in combination with i-Scan technology(one with chromoendoscopy and one without chromoendoscopy). Three databases were obtained by highmagnification endoscopy(two databases using narrow band imaging and one using chromoendoscopy). The lesions are categorized into non-neoplastic and neoplastic according to the histological diagnosis.RESULTS Generally, it is feature-dependent which imaging modalities achieve high results and which do not. For the high-definition image databases, we achieved overall classification rates of up to 79.2% with chromoendoscopy and 88.9% without chromoendoscopy. In the case of the database obtained by high-magnification chromoendoscopy, the classification rates were up to 81.4%. For the combination of high-magnification endoscopy with NBI, results of up to 97.4% for one database and up to 84% for the other were achieved. Non-neoplastic lesions were classified more accurately in general than non-neoplastic lesions. It was shown that the image recording conditions highly affect the performance of automated diagnosis systems and partly contribute to a stronger effect on the staging results than the used imaging modality.CONCLUSION Chromoendoscopy has a negative impact on the results of the methods. NBI is better suited than chromoendoscopy. High-definition and high-magnification endoscopy are equally suited.Georg Wimmer Michael Gadermayr Gernot Wolkersdorfer Roland Kwitt Toru Tamaki Jens Tischendorf Michael Hafner Shigeto Yoshida Shinji Tanaka Dorit Merhof Andreas Uhl 2019World Journal of Gastroenterology2019,25,10:2
8Fibrin glue repair leads to enhanced axonal elongation during early peripheral nerve regeneration in an in vivo mouse model显示文摘Microsurgical suturing is the gold standard of nerve coaptation. Although literature on the usefulness of fibrin glue as an alternative is becoming increasingly available, it remains contradictory. Furthermore, no data exist on how both repair methods might influence the morphological aspects(arborization; branching) of early peripheral nerve regeneration. We used the sciatic nerve transplantation model in thy-1 yellow fluorescent protein mice(YFP; n = 10). Pieces of nerve(1cm) were grafted from YFP-negative mice(n = 10) into those expressing YFP. We performed microsuture coaptations on one side and used fibrin glue for repair on the contralateral side. Seven days after grafting, the regeneration distance, the percentage of regenerating and arborizing axons, the number of branches per axon, the coaptation failure rate, the gap size at the repair site and the time needed for surgical repair were all investigated. Fibrin glue repair resulted in regenerating axons travelling further into the distal nerve. It also increased the percentage of arborizing axons. No coaptation failure was detected. Gap sizes were comparable in both groups. Fibrin glue significantly reduced surgical repair time. The increase in regeneration distance, even after the short period of time, is in line with the results of others that showed faster axonal regeneration after fibrin glue repair. The increase in arborizing axons could be another explanation for better functional and electrophysiological results after fibrin glue repair. Fibrin glue nerve coaptation seems to be a promising alternative to microsuture repair.Georgios Koulaxouzidis Gernot Reim Christian Witzel 2015Neural Regeneration Research2015,10,7:2

13高速连铸用新型浸入式水口显示文摘连铸机结晶器内钢液的流动状态严重影响连铸坯的质量,尤其在弯月面处,钢液与结晶器保护渣直接接触,结晶器内弯月面不稳定引起的卷渣,是导致产品产生缺陷的主要原因之一,如冷轧薄板的线状缺陷和厚板的表面缺陷。在结晶器润滑不均匀时,还会增加漏钢危险。弯月面液面波动主要是由于浸入式水口吐出孔钢液剧烈的湍流和瞬态行为引起的。最近,在一台连铸机上浇注不同钢种已成为全世界钢铁生产商努力的一个主要方向。为了满足所有钢种的质量要求,对每个钢种都要求一定的浇注速度。对常规的浸入式水口而言,确保结晶器内有利的流动条件是一个难题。因此,比以往更需要一种新型浸入式水口,通过保持最佳的结晶器内钢液流动状态,以各种浇注速度浇注出多规格铸坯。介绍了测试新型浸入式水口流动性能的数值模型和物理模型的试验。采用URANS方法瞬态CFD模拟表明,新型浸入式水口流出的钢液瞬态行为稳定,因而弯月面以下钢液流速较慢,其效果还通过水模拟得到了验证。现场试验是在中国台湾的中钢公司进行的,试验结果表明,通过优化结晶器内钢液的流动行为,结晶器液面波动明显减小,从而提高了产品质量。Shung Sheng Kao Hsin Chin Kua Oliver Wiens Wolfgang Mo?ner Markus Reifferscheid Nobert Vogl Gernot Hackl Gerald Nitzl 潘秀兰 2014世界钢铁2014,,1:2
