It has become clear that widespread collaboration in the scientific community, which can increasingly be characterized by geographically distributed and large-scale projects, requires predictable network service [1]. Predictable network service needed by applications such as large file transfers, remote visualization, and remote instrumentation can only be offered on connection-oriented network...

In order to achieve the virtual machines live migration, the two "pre-copy" and "post-copy" strategies are presented. Each of these strategies, depending on the operating conditions of the machine, may perform better than the other. In this article, a new algorithm is presented that automatically decides how the virtual machine live migration takes place. In this approach, the virtual machine m...

Recent experiments hint that adherent cells are sensitive to their substrate curvature. It is already well known that cells behaviour can be regulated by the mechanical properties of their environment. However, no mechanisms have been established regarding the influence of cell-scale curvature of the substrate. Using a numerical cell model, based on tensegrity structures theory and the non-smoo...

The frequency of small-scale physical damage to coral reefs is likely to increase as fishing and tourism pressures intensify. Predicting how reefs will respond to the effects of these types of damage requires empirical exploration, especially on reefs that are already heavily degraded. We replicated small-scale damage on four reefs that live close to their ecophysiological tolerance limits in t...

determination of streptokinase activity is usually accomplished through two assay methods: a) clot lysis, b) chromogenic substrate assay. in this study the biological activity of two streptokinase products, namely streptase®, which is a native product and heberkinasa®, which is a recombinant product, was determined against the third international reference standard using the two forementioned a...

A curvilinear thin film model is used to simulate the motion of droplets on a virtual leaf surface, with a view to better understand the retention of agricultural sprays on plants. The governing model, adapted from Roy et al. (2002 J. Fluid Mech. 454, 235-261 (doi:10.1017/S0022112001007133)) with the addition of a disjoining pressure term, describes the gravity- and curvature-driven flow of a s...

The stability of an amorphous Ge.$i t-,0, in contact with an epitaxial (lOO)Ge,Si,-, layer obtained by partially oxidizing an epit.axial Ge,Si,-, layer on a (1OO)Si substrate in a wet ambient at 700 “C is investigated for x=0.28 and 0.36 upon annealing in vacuum at 900 “C for 3 h, aging in air at room temperature for 5 months, and immersion in water. After annealing at 900 “C!, the oxide remain...

Navigational ability requires spatial representation, planning, and memory. It covers three interdependent domains, i.e. cognitive and perceptual factors, neural information processing, and variability in brain microstructure. Many attempts have been made to see the role of spatial representation in the navigational ability, and the individual differences have been identified in the neural subs...
