Chromatin was assembled in vitro from relaxed closed circular DNA (SV40) and core histones at histone to DNA ratios of 0.2 to 0.3 (g/g) and incubated with topoisomerase I to relax supercoils in DNA regions not constrained by protein. Addition of histones H1 + H5 to the chromatin at an ionic strength of 0.1 M, in the presence of the solubilizing agent, polyglutamic acid, and topoisomerase I, inc...

Motion planning for multiple mobile robots must ensure the optimality of the path of each and every robot, as well as overall path optimality, which requires cooperation amongst robots. The paper proposes a solution to the problem, considering different source and goal of each robot. Each robot uses a Grammar based Genetic Programming for figuring the optimal path in a maze-like map, while a ma...

Internet and IT have re-shaped the strategy logic of contemporary organizations. The new logic emphasizes business opportunity leveraging through constantly evolving entrepreneurial actions. The required business capabilities underlying such strategic logic, including organizational agility and IT competence, have also to be built and co-evolved. Based on Sambamurthy et al. [1] conceptual frame...

Edge linking is a fundamental computer-vision task, yet presents difficulties arising from the lack of information in the image. Viewed as a constrained optimisation problem, it is NP hard – being isomorphic to the classical travelling salesman problem. Self-learning neural techniques boast the ability to solve hard, ill-defined problems and, hence, offer promise for such an application. This p...

Causal knowledge based on causal analysis can advance the quality of decision-making and thereby facilitate a process of transforming strategic objectives into effective actions. Several creditable studies have emphasized the usefulness of causal analysis techniques. Partial least squares (PLS) path modeling is one of several popular causal analysis techniques. However, one difficulty often fac...

Path planning is an essential component in the control software for an autonomous mobile robot. Evolutionary strategies are employed to determine optimal paths for their robustness and ability to solve complex problems. However, current evolutionary approaches fail to consider varying terrain conditions when determining an optimal path and offer only path planning without trajectory planning. T...

ROSAT has discovered a new group of isolated neutron stars characterized by soft blackbody like spectra (kT ∼ 50-120 eV), apparent absence of radio emission and no association with supernovae remnants. So far only six such sources are known. A small fraction of these stars exhibit X-ray pulsations with relatively long periods of the order of 10 sec. Two very different mechanisms may be envisage...

Half a century is fast approaching since Hayflick and colleagues formally described the limited ability of normal human cells to proliferate in culture (Hayflick and Moorhead, 1961). This finding – that normal somatic cells, in contrast to cancer cells, cannot divide indefinitely – challenged the prevailing idea that cells from mortal multicellular organisms were intrinsically ‘immortal’ (Carre...

Location tracking technologies are penetrating increasingly in industrial environments. Several challenges arise when people or mobile assets are tracked. Security is one of the main problems that location tracking poses. In this position paper we want to address the long-term authentication and accountability of location tracking history information or path. In order to accomplish this, we gen...
