For efficient ligand binding, integrins must be activated. Specifically, a conformational change has been proposed in a ligand binding domain present within some integrins, the inserted (I) domain [Lee, J., Bankston, L., Arnaout, M. & Liddington, R. C. (1995) Structure (London) 3, 1333-1340]. This proposal remains controversial, however, despite extensive crystal structure studies on the I doma...

Abstract The diffusivities along the whole diffusion path in one couple of Ni-rich fcc Ni–Al–Cu alloys at 1273, 1333 and 1433 K are obtained by means numerical inverse method. In total 12 couples used to obtain intersections paths Matano–Kirkaldy Two sets atomic mobilities assessed using CALTPP program based on calculated method method, respectively. validity is confirmed comparing model-predic...

Outflows from young stellar objects have been identified as a possible source of turbulence in molecular clouds. To investigate the relationship between outflows, cloud dynamics and turbulence, we compare the kinematics of the molecular gas associated with NGC 1333, traced in CO(1-0), with the distribution of young stellar objects (YSOs) within. We find a velocity dispersion of ∼ 1− 1.6km/s in ...
