目的 观察舌三针联合间歇性θ爆发刺激（intermittent theta burst stimulation,iTBS）对脑卒中后吞咽障碍患者吞咽功能及表面肌电（surface electromyography,sEMG）的影响。方法 将40例脑卒中后吞咽障碍患者随机分为对照组和观察组,每组20例;两组患者均进行常规吞咽训练,对照组在此基础上行舌三针治疗,观察组在对照组治疗基础上增加iTBS治疗,疗程均为4周;观察和比较两组患者治疗前后洼田饮水试验（water swallowing test,WST）评分、标准吞咽功能评估（standardized swallowing assessment,SSA）量表评分、吞咽生活质量（swallowing quality of life,SWAL-QOL）量表评分、sEMG最大波幅值及吞咽时程。结果 治疗后两组患者WST评分、SSA量表评分、吞咽时程均较治疗前显著减少（P＜0.05）,SWAL-QOL量表评分、sEMG最大波幅值均较治疗前显著增加（P＜0.05）;且观察组WST评分、SSA量表评分、吞咽时程减少程度,SWAL-QOL量表评分、sEMG最大波幅值增加程度均显著大于对照组（P＜0.05）。结论 舌三针联合iTBS治疗可显著改善脑卒中后吞咽障碍患者吞咽功能并提高生活质量。     

Reconstruction of Banknote Fragments Based on Keypoint Matching Method

Banknotes may be shredded by a scrap machine, ripped up by hand, or damaged in accidents. This study proposes an image registration method for reconstruction of multiple sheets of banknotes. The proposed method first constructs different scale spaces to identify keypoints in the underlying banknote fragments. Next, the features of those keypoints are extracted to represent their local patterns around keypoints. Then, similarity is computed to find the keypoint pairs between the fragment and the reference banknote. The banknote fragments can determine the coordinate and amend the orientation. Finally, an assembly strategy is proposed to piece multiple sheets of banknote fragments together. Experimental results show that the proposed method causes, on average, a deviation of 0.12457 ± 0.12810° for each fragment while the SIFT method deviates 1.16893 ± 2.35254° on average. The proposed method not only reconstructs the banknotes but also decreases the computing cost. Furthermore, the proposed method can estimate relatively precisely the orientation of the banknote fragments to assemble.     

A survey of glass fragments recovered from clothing of persons suspected of involvement in crime

The refractive indices (RI) of over 2000 glass fragments recovered from items of clothing submitted to the Birmingham and Wetherby Home Office forensic science laboratories in connection with crimes involving broken glass have been measured. The glass fragments have been classified according to their location on the clothing, and a grouping algorithm has been applied to the data.The refractive index distribution was found to be dependent on the location of the glass on the clothing. The significance of the results in the interpretation of glass evidence is discussed.     

中国入世后外资审批中存在的问题及立法思考——从环保角度看外资审批

引入外资,带动了我国经济的发展。然而,由于我国外资审批立法上存在诸多问题,再加上西方发达国家目前正在实行的“污染转移”的政策,使大量不合格的外资企业进入了中国,从而引发了一系列的外资所带来的环境污染的问题。为有效解决引入外资所带来的环境污染问题,必须重新界定审批标准减少其中的自由裁量权,确立环保审批以杜绝“地方保护”,明确审批行使人的法律责任以及建立对于审批权行使的监督体系。     

赫勒历史哲学思想的发展历程

关于历史问题的思考及对现代性问题的历史反思与历史重构是赫勒哲学思想的重要方面。赫勒历史哲学思想的发展历程大致经历了三个阶段,实质上就是从构建一种历史理论的体系,到碎片化的历史断想,再到现代性历史反思与重构的发展过程。     

伪狂犬病病毒gG-gD基因片段的扩增及克隆和序列测定

以伪狂犬病病毒(PRV)HB-9304株的基因组为模板,利用聚合酶链反应(PCR)对其gG-gD基因片段进行扩增,获得了预定大小的片段,将这一片段克隆到质粒载体pPK中.对重组质粒pPKGD进行限制性内切酶分析、PCR鉴定和克隆片段的序列测定,证实了克隆片段的可靠性.     

创新职务犯罪预防机制高效服务和谐社会建设

职务犯罪产生的根本原因是职务主体内在履职心理与外部履职环境严重不和谐并相互作用的结果,预防职务犯罪工作应按照和谐社会建设的要求,从消除职务主体的内外不和谐因素入手,坚持打防并举、标本兼治的方针,建立和完善"教育、制度、监督、法治"四位一体的预防机制,以高效服务于和谐社会建设.     

自制漫反射拍摄装置拍摄光滑圆柱面客体上指纹

利用光的漫反射原理,自制一种操作简单的装置,解决拍摄光滑圆柱面客体上的指纹直接打光出现反光带的问题。实验结果表明,采用直接打光无论采取什么角度和什么光源时光滑圆柱客体进行拍摄都很难避开强反光带,本实验采用的自制装置产生的漫反射光均匀,通过间接照明,使物证处在一个半封闭的均匀的光线环境中,可有效地避开强反光带,取得了拍摄光滑圆柱面客体表面的指纹的较好效果。     

Degradation of polymer banknotes through handling,and effect on fingermark visualisation

The surface structure of mint (as-issued) and handled polymer five pounds sterling banknotes was studied by atomic force microscopy and laser scanning confocal microscopy. A total of 1856 fingermarks on mint and handled banknotes from four different issuing banks (Bank of England, Bank of Scotland, Royal Bank of Scotland and Clydesdale Bank) were visualised with Vacuum Metal Deposition (VMD), Cyanoacrylate Fuming (CAF) and, on Clydesdale Bank notes, magnetic fluorescent powder. VMD was significantly more effective in developing fingermarks on handled banknotes, across all the banks studied, although effectiveness varied with issuing bank. For example, on handled Bank of England notes 45% of marks showed ridge detail with VMD development and 28% with CAF; for Bank of Scotland handled notes success rates were 17% with VMD and 1% with CAF. Microscopy of degraded banknotes showed the loss of intaglio printing and the formation of a cracked surface structure in the handled notes. These features can lead to the trapping of powder, or contaminants, increasing quantity of development agent in fingermark background between the ridges, decreasing contrast and decreasing performance of powder-based fingermark development techniques. These same features can restrict the migration of components of the fingermark, preventing fingermarks degrading through spread of material and thus reducing potential formation of empty prints, so that VMD development is not adversely affected.
