Cells move differently on substrates with different rigidities: the persistence time of their motion is higher on stiffer substrates. We show that this behavior-in and of itself-results in a net flux of cells directed up a soft-to-stiff gradient. Using simple random walk models with varying persistence and stochastic simulations, we characterize the propensity to move in terms of the durotactic...

There is good evidence that morbidity and mortality increase for young persons (YP) following the move from paediatric to adult services. Studies show that effective transition between paediatric and adult care improves long-term outcomes. Many of the issues faced by young people across subspecialties with a long-term condition are generic. This article sets out some of the obstacles that have ...

In this paper we present a Path-Planning Algorithm for a non-holonomic mobile robot with a generic shape. The robot we considered has to move using smoothed trajectories respecting a minimum steering radius constraint. We have developed an algorithm based on a directional (anisotropic) propagation of attracting potential values on a Multilayered Cellular Automata Model. The algorithm finds all ...

the present study aimed to investigate the generic organization of research article introductions in local iranian and international journals in english for specific purposes, english for general purposes, and discourse analysis. overall, 120 published articles were selected from the established journals representing the above subdisciplines. each subdiscipline was represented by 20 local and 2...

Abstract Abstract Background: Availability and affordability of medicines are crucial to achieving success in prevention programs, particularly in developing countries. Objective: The aim of this study was to determine the availability and affordability of cardiovascular medicines for secondary prevention in Tehran province of Iran. Methods: A cross-sectional survey was conducted in Tehran pro...

this contrastive study, in the first place, examined the generic structure and, in the second place, explored the face theory proposed by arundale (2006) in 140 doctoral dissertation acknowledgments written by native speakers of persian (nsp) and native speakers of english (nse) in 7 disciplines representing soft sciences to find out what discourse genre components writers employ to articulate ...

In this position paper we present S-MOVE (Smart and Social Move), a social innovation project funded by MIUR (Italian Ministry of Education, Research and University). SMOVE is based on a new conception of urban community, that allows citizens to share data and decisions in a smart and innovative way. In order to implement this new vision of urban mobility, called smart mobility, a deep integrat...

Previous work on self-reconfiguring modular robots has concentrated primarily on designing hardware and developing reconfiguration algorithms tied to specific hardware systems. In this paper, we introduce a generic model for lattice-based self-reconfigurable robots and present several generic locomotion algorithms that use this model. The algorithms presented here are inspired by cellular autom...

Existing fossil fuels do not meet the needs of modern societies and are almost coming to an end. Hence, governments can respond both to the needs of the people and the industry, by investing in the use of renewable energies. As well as saving fossil fuels, natural gas and even water. According to the research, renewable energy, especially wind energy, has been used in recent years and are able ...
