Invasive cells use small invadopodia to breach basement membrane (BM), a dense matrix that encases tissues. Following the breach, a large protrusion forms to clear a path for tissue entry by poorly understood mechanisms. Using RNAi screening for defects in Caenorhabditis elegans anchor cell (AC) invasion, we found that UNC-6(netrin)/UNC-40(DCC) signaling at the BM breach site directs exocytosis...

To gather articles, we searched three literature databases of Scopus, ABI/Inform, and Google Scholar. We looked for all articles that contained various keywords, such as “data breach,” “security breach,” “privacy breach,” and “information breach.” We then narrowed our focus to include scholarly articles, excluding articles in the popular and practitioner media. Most of the articles identified i...

Considering wireless sensor networks for border surveillance, one of the major concerns is sensing coverage. Breach probability can be used as a measure to analyze the tradeoffs and to determine the required number of sensors to be deployed to obtain a certain security level. In this paper, the sensing coverage of surveillance wireless sensor networks is studied by utilizing a well-known image ...

Trust development is a critical aspect of computersupported cooperative work (CSCW). Trust is especially important in distributed work environments because of the limited amount of social presence afforded by computer-based communication media. Although several studies have studied trust development in computer-mediated environments, very few have researched the reparation of trust, following a...

In this paper, the sensing coverage area of surveillance wireless sensor networks is considered. The sensing coverage is determined by applying the Neyman-Pearson detection model and defining the breach probability on a gridmodeled field. Using a graph model for the perimeter, Dijkstra’s shortest path algorithm is used to find the weakest breach path. The breach probability is linked to paramet...

Metastasis is initiated in epithelial-derived tumors when cells at the tumor front breach the epithelial basement membrane (BM). Invasion through BMs is thought to be one of the most rate-limiting steps in cancer progression and thus is a therapeutically attractive target for halting tumor spread. Despite intense interest, it has been challenging to experimentally determine how invasive cells b...
