The authors performed a comprehensive review of current literature to create a model comparing commonly evaluated variables in male factor infertility,for example,follicle-stimulating hormone(FSH),testicular volume(TV),and testosterone(T),to better predict sperm retrieval rate(SRR).Twenty-nine studies were included,9 with data on conventional testicular sperm extraction(cTESE)for a total of 1227 patients and 20 studies including data on microdissection testicular sperm extraction(mTESE)for a total of 4760 patients.A weighted-means value of SRR,FSH,T,and TV was created,and a weighted linear regression was then used to describe associations among SRR,type of procedure,FSH,T,and *** this study,weighted-means values demonstrated mTESE to be superior to cTESE with an SRR of 51.9%vs 40.1%.Multiple weighted linear regressions were created to describe associations among SRR,procedure type,FSH,T,and *** models showed that for every 1.19 mIU ml^(−1)increase in FSH,there would be a significant decrease in SRR by 1.0%.Seeking to create a more clinically relevant model,FSH values were then divided into normal,moderate elevation,and significant elevation categories(FSH20 mIU ml^(−1),respectively).For an index patient undergoing cTESE,the retrieval rates would be 57.1%,44.3%,and 31.2%for values normal,moderately elevated,and significantly elevated,*** conclusion,in a large meta-analysis,mTESE was shown to be more successful than cTESE for sperm *** has an inverse relationship to SRR in retrieval techniques and can alone be predictive of cTESE SRR.

Subregion graph: A path planning acceleration structure for characters with various motion types in very large environments

引用

Computational Visual Media 2015年第2期1卷 105-118页

作者： nicholas Mario Wardhana Henry Johan Hock Soon Seah Multi-plAtform Game Innovation Centre(MAGIC) Nanyang Technological University School of Computer Engineering Nanyang Technological University Fraunhofer IDM NTU Nanyang Technological University

Modern computer graphics applications commonly feature very large virtual environments and diverse characters which perform different kinds of motions. To accelerate path planning in such a scenario, we propose the subregion graph data structure. It consists of subregions, which are clusters of locally connected waypoints inside a region, as well as subregion connectivities. We also present a fast algorithm to automatically generate a subregion graph from an enhanced waypoint graph map representation,which also supports various motion types and can be created from large virtual environments. Nevertheless,a subregion graph can be generated from any graphbased map representation. Our experiments show that a subregion graph is very compact relative to the input waypoint graph. By firstly planning a subregion path, and then limiting waypoint-level planning to this subregion path, over 8 times average speedup can be achieved, while average length ratios remain as low as102.5%.
