During their passage through the circulatory system, tumor cells undergo extensive interactions with various host cells including endothelial cells and platelets. Mechanisms mediating tumor cell adhesion, migration, and metastasis to vessel wall under flow condition are largely unknown. The aim of this study was to investigate the potential roles of GPIIb/IIIa and alphavbeta3 integrins underlyi...

This paper explains the effect of a motion platform closed loop control comparing to the static condition for driving simulators on postural instability. The postural instabilities of the participants (N=18, 15 male and 3 female subjects) were measured as lateral displacements of subject body centre of pressure (YCP ) just before and after each driving session via a balance platform. After havi...

We present a new static analysis to infer necessary field conWe present a new static analysis to infer necessary field conditions for object-oriented programs. A necessary field condition is a property that should hold on the fields of a given...

This contribution reports on ongoing collaborative research at the University of Stanford, Department of Psychology, and the University of Hamburg, Department for Informatics. Extending the research on the effects of static vs. dynamic route presentation on perception and memory (Klippel et al., 2002), we examined different route presentation methods that are commonly used today (e.g. internet ...

This longitudinal study aimed to compare static postural stability in women between early pregnancy, advanced pregnancy, and at 2 and 6 months postpartum. Forty-five pregnant women were enrolled and 31 completed the protocol. Data were collected at 7-16 and 34-39 weeks gestation, and at 6-10 and 26-30 weeks postpartum. For each subject, the center of foot pressure path length and mean velocity ...

Several studies have shown that the transmission of afferent inputs from the periphery to the somatosensory cortex is attenuated during the preparation of voluntary movements. In the present study, we tested whether sensory attenuation is also observed during the preparation of a voluntary step. It would appear dysfunctional to suppress somatosensory information, which is considered to be of th...

Steam Turbines are devices used to convert thermal energy of steam into mechanical energy, which may be used to produce Electrical Energy. Steam turbine generator units are being used extensively all over the world for generation of electric power and for co-generation of steam and power. Contact pressure and pretension in bolts-analysis has been made easier in recent years due to the availabil...

BACKGROUND AND AIMS The objective of this non-randomized study was to determine the influence of a specific physical activity program on the postural stability of older people. METHODS Seventy-four subjects (72.4 +/- 0.7 yrs) participated in an individualized three-month physical activity program designed to improve posture, balance and mobility--the PBM program. Sessions were held twice week...

Static and stationary regular black holes are examined under a minimal set of requirements consisting (i) the existence well defined event horizon (ii) weak energy condition for matter sourcing geometry. We perform our analysis by means gravitational decoupling approach find hairy solutions free curvature singularities. identify source producing deformation Minkowski vacuum such that maximum is...
