A comparative definition for community in networks is proposed, and the corresponding detecting algorithm is given. A community is defined as a set of nodes, which satisfies the requirement that each node's degree inside the community should not be smaller than the node's degree toward any other community. In the algorithm, the attractive force of a(More)
Epidermal growth factor (EGF) mediates breast cancer cell chemotaxis and metastasis through mechanisms that involve the growth-regulatory mammalian target of rapamycin (mTOR) complex mTORC2, but the mechanisms involved remain obscure. Here, we report that the rapamycin-insensitive mTORC2 component protein Rictor is a critical mediator of metastasis in(More)
OBJECTIVE To report successful treatment by laparoscopically assisted biomaterial graft for reconstruction in patients with congenital atresia of the uterine cervix and vagina. DESIGN Technique and instrumentations. SETTING University-based tertiary care hospital. PATIENT(S) An 18-year-old woman with vaginal agenesis and cervical dysgenesis and a(More)
This paper demonstrates an in vitro model to simulate the microenvironment of endometriosis. We used microfluidic channels with cover slips to pattern and release endometrial stromal cells (ESCs) and human peritoneal mesothelial cells (HPMCs) in a way that mimicked the pathophysiology of peritoneal endometriosis. This approach enabled observation in real(More)
There is considerable interest in using traditional Chinese medicine formulas (TCMF) to delay aging or treat age-related diseases. Due to cost and duration, the beneficial effects of TCMF on prolongation are mainly extrapolated from vitro studies or physiological indexes. Little is known about whether TCMF are beneficial in whole level, particularly with(More)
Although it has been known for many years that Eimeria acervulina (E. acervulina) initiates infection by invading the duodenal epithelial cells of chicken, the key protein molecules and the mechanisms of the parasite in invading are unknow. In this study, we found that 85 proteins of E. acervulina could bind with the chicken duodenal epithelial cells from(More)
Based on a signaling process of complex networks, a method for identification of community structure is proposed. For a network with n nodes, every node is assumed to be a system which can send, receive, and record signals. Each node is taken as the initial signal source to excite the whole network one time. Then the source node is associated with an n(More)
Inspired by scientific collaboration networks, especially our empirical analysis of the network of econophysicists, an evolutionary model for weighted networks is proposed. Both degree-driven and weight-driven models are considered. Compared with the BA model and other evolving models with preferential attachment, there are two significant generalizations.(More)
In order to take the weight of connection into consideration and to find a natural measurement of weight, we have collected papers in Econophysics and constructed a network of scientific communication to integrate idea transportation among econophysicists by collaboration, citation and personal discussion. Some basic statistics such as weight per degree are(More)
The development of Econophysics is studied from the perspective of scientific communication networks. Papers in Econophysics published from 1992 to 2003 are collected. Then a weighted and directed network of scientific communication, including collaboration, citation and personal discussion, is constructed. Its static geometrical properties, including(More)
