Blood, 2009
Abstract In this issue of Blood, Zou and colleagues unravel a long-standing mystery—how megakaryocyte precursors make the transition from the collagen-rich osteoblastic bone marrow niche to the collagen-poor vascular niche while expressing 2 receptors that interact with collagen—GpVI and the α2β1 integrin.

Neurology, 1992
I performed a pupillographic study of pupillary escape to determine its effectiveness in detecting optic nerve and retinal disease. Fourteen patients and 39 normal subjects were included in the study. Only one patient had abnormal pupillary escape, even though 13 patients had relative afferent pupillary defects.

International Journal of Theoretical Physics, 1999
The author considers a dynamical system consisting of infinite number of rigid bodies of arbitrary size and subject to mutual elastic collisions alone, without any gravitational interaction. The author obtains a solution for equations of Newtonian mechanics which becomes unbounded in a finite time (a process called here escape to infinity.

The Great Escape: Junctional Escape—Capture Bigeminy
The American Journal of Geriatric Cardiology, 2006Escape—capture bigeminy is a bigeminal rhythm in which each escape beat is followed by a captured beat. This dysrhythmia is very rare, because its manifestation requires the sinus interval to be longer than the escape interval. This is possible only with severe sinus nodal disease, where the intrinsic sinus rate is extremely low, or with ...

ESCAPES: evacuation simulation with children, authorities, parents, emotions, and social comparison
Adaptive Agents and Multi-Agent Systems, 2011In creating an evacuation simulation for training and planning, realistic agents that reproduce known phenomenon are required. Evacuation simulation in the airport domain requires additional features beyond most simulations, including the unique ...

TO ESCAPE OR NOT TO ESCAPE, THAT IS THE QUESTION — PERTURBING THE HÉNON–HEILES HAMILTONIAN
International Journal of Bifurcation and Chaos, 2012In this work, we study the Hénon–Heiles Hamiltonian, as a paradigm of open Hamiltonian systems, in the presence of different kinds of perturbations as dissipation, noise and periodic forcing, which are very typical in different physical situations. We focus our work on both the effects of these perturbations on the escaping dynamics and on the basins ...

Escaping Regulation, Escaping Convention
World Economics Journal, 2004Contrary to widely held belief, small island countries have many lessons to offer to other countries and the world community in terms of their development strategies. This article provides evidence that small island countries are experts at breaking and distorting global trade rules without being noticed or provoking retaliatory actions. As unimportant
