During the past decade, infection prevention programs have been presented with an unending series of challenges and expectations. The challenges, more often than not, have resulted in additional responsibilities, functions, and workload for infection control professionals (ICPs) and healthcare epidemiologists. These additional responsibilities have not been accompanied by proportional increases...

To study the social organisation of sets of agents managing common property goods, we use multi-agent simulations. This paper describes how the idea of group is analysed in this context. On the one hand agents build constantly themselves and the community, through their actions on their common environment and their different interactions with others. On the other hand the group preexists to the...

We show herein how mechanical forces at macro or micro scales may affect the biological response at the nanoscale. The reason resides in the intimate link between chemistry and mechanics at the molecular level. These interactions occur under dynamic conditions such as the shear stress induced by flowing blood or the intracellular tension. Thus, resisting removal by mechanical forces, e.g., shea...

This paper is focused on the computational analysis of collective discourse, a collective behavior seen in nonexpert content contributions in online social media. We collect and analyze a wide range of real-world collective discourse datasets from movie user reviews to microblogs and news headlines to scientific citations. We show that all these datasets exhibit diversity of perspective, a prop...

Tumour cells employ a variety of mechanisms to invade their environment and to form metastases. An important property is the ability of tumour cells to transition between individual cell invasive mode and collective mode. The switch from collective to individual cell invasion in the breast was shown recently to determine site of subsequent metastasis. Previous studies have suggested a range of ...
