Asian Journal of Andrology 2001年第3期3卷 235-237页

作者： Li-Xin QIAN Hong-Fei WU yuan-geng shui Wei ZHANG Shuang-Guan CHENG Min GU Zheng-Quan XU Department of Urology, First Affiliated Hospital,Nanjing Medical University, Nanjing 210029, China Department of Urology First Affiliated Hospital Nanjing Medical University Nanjing 210029 China

Aim: To put forward criteria for the pressure assessment in the operation of intercavernous embedding of bulboper-ineal urethra for the treatment of urinary incontinence after prostatic operation. Methods: A F14 urethral catheter isinserted during the operation and upon suturing the corpora cavernosa centrally, the catheter is slowly pushed in andpulled out in order that the operator feels a certain degree of close-fit resistance. The degree of tightness of the stitches,which regulate the compression pressure, is adjusted in accordance with this close-fit sensation. To further ascertain theadequacy of the force of compression, the bladder is filled with 300 ml physiological saline and observe the appropriate-ness (size and continuity) of the outflow stream when the lower abdomen is depressed with a pressure of 80 - 90 cmH_2O. The operation was given to six patients suffered from urinary incontinence for 20 or more months after prostaticoperation. Results: Five cases achieved complete recovery, while the therapeutic effect of the 6th one was not sat-isfactory . A second stage operation was carried out 3 months later with the addition of one more stitch both proximallyand distally to reinforce the compression force. The condition was improved dramatically. The follow-up period aver-aged 3.5 years. Conclusion; The adequacy of the compression pressure exerted by the juxtaposed corpora cavernosais the key point determining the outcome of the operation. The measures for assessing the compression pressure suggest-ed by the authors are helpful in obtaining the good results of the present paper (6/6 success) as compared with 25/34success in the previous report.

A Robust Face Recognition Method Combining LBP with Multi-mirror Symmetry for Images with Various Face Interferences

引用

International Journal of Automation and computing 2019年第5期16卷 671-682页

作者： shui-Guang Tong yuan-yuan Huang Zhe-Ming Tong State Key Laboratory of Fluid Power and Mechatronic Systems Zhejiang UniversityNo.38Zheda RoadHangzhou 310027China School of Mechanical Engineering Zhejiang UniversityNo.38Zheda RoadHangzhou 310027China

Face recognition(FR) is a practical application of pattern recognition(PR) and remains a compelling topic in the study of computer vision. However, in real-world FR systems, interferences in images, including illumination condition, occlusion, facial expression and pose variation, make the recognition task challenging. This study explored the impact of those interferences on FR performance and attempted to alleviate it by taking face symmetry into account. A novel and robust FR method was proposed by combining multi-mirror symmetry with local binary pattern(LBP), namely multi-mirror local binary pattern(MMLBP). To enhance FR performance with various interferences, the MMLBP can 1) adaptively compensate lighting under heterogeneous lighting conditions, and 2) generate extracted image features that are much closer to those under well-controlled conditions(i.e., frontal facial images without expression). Therefore, in contrast with the later variations of LBP, the symmetrical singular value decomposition representation(SSVDR) algorithm utilizing the facial symmetry and a state-of-art non-LBP method, the MMLBP method is shown to successfully handle various image interferences that are common in FR applications without preprocessing operation and a large number of training images. The proposed method was validated with four public data sets. According to our analysis, the MMLBP method was demonstrated to achieve robust performance regardless of image interferences.

Unique inter-skeleton conductive films are constructed in polymer *** resistance change of the foam can reach four orders of magnitude under *** foam exhibits strain-adaptive electromagnetic interference shielding performance, anti-interference pressure sensor with high sensitivity over a wide pressure range and compression-regulated Joule heating function. Conductive polymer foam (CPF) with excellent compressibility and variable resistance has promising applications in electromagnetic interference (EMI) shielding and other integrated functions for wearable electronics. However, its insufficient change amplitude of resistance with compressive strain generally leads to a degradation of shielding performance during deformation. Here, an innovative loading strategy of conductive materials on polymer foam is proposed to significantly increase the contact probability and contact area of conductive components under compression. Unique inter-skeleton conductive films are constructed by loading alginate-decorated magnetic liquid metal on the polymethacrylate films hanged between the foam skeleton (denoted as AMLM-PM foam). Traditional point contact between conductive skeletons under compression is upgraded to planar contact between conductive films. Therefore, the resistance change of AMLM-PM reaches four orders of magnitude under compression. Moreover, the inter-skeleton conductive films can improve the mechanical strength of foam, prevent the leakage of liquid metal and increase the scattering area of EM wave. AMLM-PM foam has strain-adaptive EMI shielding performance and shows compression-enhanced shielding effectiveness, solving the problem of traditional CPFs upon compression. The upgrade of resistance response also enables foam to achieve sensitive pressure sensing over a wide pressure range and compression-regulated Joule heating function.

武汉理工大学学报 2010年第17期32卷 99-102页

作者： geng H N shui Z H School of Materials Science and Engineering Wuhan University of TechnologyWuhan 430070China

Influence of fly ash addition on the hydrationof Portland cement clinker,particularly at the initial stage,has been studied on the basis of measured data obtained. Fly ash,considering its active components,was added as a partial replacement of Portland cement at different water/cementitious ratios. The hydration heat was measured in a controlled environmental room of 20 ℃. Both non-evaporable water content and mineral phase were investigated. Data indicate that the amount of fly ash involved in hydration reaction is little at initial stage while it becomes more after 7 d hydration. As hydration reaction is a continuous process,chemical stress results in the disruption of stable structure on the surface of fly ash consisting of Ca,O,Si,Al,C,etc. Additionally,surface of glass beads begins to lose smooth and reacts to blend in with the paste.

NLOS error mitigation with information fusion algorithm for UWB ranging systems

引用

The Journal of China Universities of Posts and Telecommunications 2012年第2期19卷 22-29页

作者： JIANG Xiang-yuan ZHANG Huan-shui WANG Wei School of Control Science and Engineering Shandong UniversityJinan 250061China

This article puts forward a scalar weighting information fusion （IF） smoother with modified biased Kalman filter （BKF） and maximum likelihood estimation （MLE） to mitigate the ranging errors in ultra wide band （UWB） systems. The information fusion algorithm uses both the time of arrival （TOA） and received signal strength （RSS） measurement data to improve the ranging accuracy. At first, the ranging protocol of IEEE 802.15.4a acts as a multi-sensor system with multi-scale sampling. Then the scalar-based IF smoother accurately estimates the range measurement in the line of sight （LOS） and non-line of sight （NLOS） condition of UWB sensor network, during which the effectiveness of the IF in mitigating errors is especially focused during the LOS/NLOS transitions. Simulation results show that the proposed hybrid TOA-RSS fusion approach indicates a performance improvement compared with the usual TOA-only and other IF method, and the estimated ranging metrics can be used for achieving higher accuracy in location estimation and target tracking.

Nitric Oxide Blocks Blue Light-Induced K^+ Influx by Elevating the Cytosolic Ca^(2+) Concentration in Vicia faba L. Guard Cells

引用

Journal of Integrative Plant Biology 2013年第6期55卷 527-536页

Ca2＋ plays a pivotal role in nitric oxide （NO）-promoted stomatal closure. However, the function of Ca2＋ in NO inhibition of blue light （BL）-induced stomatal opening remains largely unknown. Here, we analyzed the role of Ca2＋ in the crosstalk between BL and NO signaling in Vicia faba L. guard cells. Extracellular Ca2＋ modulated the BL-induced stomatal opening in a dose-dependent manner, and an application of 5 μM Ca2＋ in the pipette solution significantly inhibited BL-activated K＋ influx. Sodium nitroprusside （SNP）, a NO donor, showed little effect on BL-induced K＋ influx and stomatal opening response in the absence of extracellular Ca2＋ , but K＋ influx and stomatal opening were inhibited by SNP when Ca2＋ was added to the bath solution. Interestingly, although both SNP and BL could activate the plasma membrane Ca2＋ channels and induce the rise of cytosolic Ca2＋ , the change in levels of Ca2＋ channel activity and cytosolic Ca2＋ concentration were different between SNP and BL treatments. SNP at 100 μM obviously activated the plasma membrane Ca2＋ channels and induced cytosolic Ca2＋ rise by 102.4%. In contrast, a BL pulse （100 μmol/m 2 per s for 30 s） slightly activated the Ca2＋ channels and resulted in a Ca2＋ rise of only 20.8%. Consistently, cytosolic Ca2＋ promoted K＋ influx at 0.5 μM or below, and significantly inhibited K＋ influx at 5 μM or above. Taken together, our findings indicate that Ca2＋ plays dual and distinctive roles in the crosstalk between BL and NO signaling in guard cells, mediating both the BL-induced K＋ influx as an activator at a lower concentration and the NO-blocked K＋ influx as an inhibitor at a higher concentration.

The cytoplasmic droplet may be indicative of sperm motility and normal spermiogenesis

引用

Asian Journal of Andrology 2013年第6期15卷 799-805,I0009页

作者： Hui Xu shui-Qiao yuan Zhi-Hong Zheng Wei Yam Department of Laboratory Animal Medicine China Medical University Shenyang 110001 China and Department of Physiology and Cell Biology University of Nevada School of Medicine Reno NV 89557 USA

Although the cytoplasm of spermatids is removed at the end of spermiogenesis, a tiny portion is usually retained in the sperm flagellum, which is termed the cytoplasmic droplet （CD） in mammals. CDs are believed to play a role in sperm volume adaptation. However, we have noticed that epididymal spermatozoa that display initial （flagellation in situ） and progressive motility mostly possess CDs, whereas spermatozoa without CDs are rarely motile, suggesting that CDs have a role in motility development during sperm epididymal maturation. In the present study, we analyzed the relationship between the presence or absence of CDs, motility development and positional changes of CDs during sperm epididymal maturation in mice and monkeys. We also examined CDs on spermatozoa of three knockout mouse lines with late spermiogenic defects. Our data suggest that the CD is a normal organelle transiently present exclusively on epididymal spermatozoa, and normal CD morphology and location are associated with normal motility development during epididymal maturation of spermatozoa. Abnormal CD formation, e.g., a complete lack of CDs or ectopic CDs, is indicative of defective spermiogenesis. If CDs are essential for sperm motility development, then CDs may represent an ideal drug target for the development of non-hormonal male contraceptives.
