Many cellular systems rely on the ability to interpret spatial heterogeneities in chemoattractant concentration to direct cell migration. The accuracy of this process is limited by stochastic fluctuations in the concentration of the external signal and in the internal signaling components. Here we use information theory to determine the optimal scheme to detect the location of an external chemo...

OLOMAS’02 is the third workshop organized within the frame of the DEXA conference. The first two workshops (HOLOMAS’00 held in Greenwich, UK, HOLOMAS’01 in Munich) documented the imperative need in starting mutual communication and cooperation between two research communities who were at the time working in parallel without any deeper interaction. That is, the AI community aimed at multi-agent ...

BACKGROUND Due to worldwide migration to Western countries, physicians are increasingly encountering patients with different ethnic backgrounds. Communication problems can arise as a result of differences in cultural backgrounds and poor language proficiency. AIMS To assess the effectiveness of an educational intervention on intercultural communication aimed to decrease inequalities in care p...

The evolution of a system consisting of a protoplanetary disc with two embedded Jupiter sized planets is studied numerically. The disc is assumed to be flat and nonself gravitating, which is modeled by the planar (two-dimensional) Navier-Stokes equations. The mutual gravitational interaction of the planets and the star, and the gravitational torques of the disc acting on the planets and the cen...

Context Many object-oriented designs contain bidirectional relationships between objects, where an instance of one class is linked to an instance of another class and vice-versa. These are normally represented in terms of two unidirectional relationships – conventional programming languages provide unidirectional object pointers or references but rarely support any bidirectional constructs. Pro...

The Rho GTPase family accounts for as many as 20 members. Among them, the archetypes RhoA, Rac1, and Cdc42 have been the most well-characterized. Like all members of the small GTPases superfamily, Rho proteins act as molecular switches to control cellular processes by cycling between active, GTP-bound and inactive, GDP-bound states. The 14-3-3 family proteins comprise seven isoforms. They exist...

The problem of migrations is always relevant, as the movement large masses people affects political and economic foundations many states. Middle Ages are no exception, it was then during development feudal monarchical states that various types migration flourished. paper devoted to study peculiarities processes existence early state – Kyivan Rus, which can be considered beginning statehood mode...

Refugees who resettle in a new country face numerous struggles, including overcoming past traumas and coping with post-migration stressors, such as lack of meaningful social roles, poverty, discrimination, lack of environmental mastery, and social isolation. Thus, in addition to needing to learn concrete language skills and gain access to resources and employment, it is important for refugees t...
