the verge of showing the potential clinical value of embryonic stem cell research. Our research clearly shows that stem-cell-derived retinal cells can rescue visual function in animals that otherwise would have gone blind. We are hopeful that the cells will be similarly efficacious in patients. " The company hopes to start its clinical trial this spring. At a later point, the company also hopes...

In this paper, we demonstrate the ease in which an adaptive simulated annealing algorithm can be designed. Specifically, we use the adaptive annealing schedule known as the modified Lam schedule to apply simulated annealing to the weighted tardiness scheduling problem with sequence-dependent setups. The modified Lam annealing schedule adjusts the temperature to track the theoretical optimal rat...

This research uses an appropriation perspective to explore how project management norms are concretely used in context. We have drawn on AST (Adaptive Structuration Theory) to study the appropriation of norms by I.T project managers, using three case studies. Direct appropriation moves have been observed from each project manager, as well as faithfulness to the spirit of PM norms. However a tho...

The present day ever escalating power demand moves the operating point ofthe distribution networks in vicinity of voltage stability boundaries.Any small reactive unbalance between generation and demandmay trigger instability, which makes magnitude to fallslowly until a rapid change occurs. This paper presents an adaptive dragonflyoptimization based method for placement shunt capacitor banks wit...

abstract rhetorical structure is helpful in improving how the writers maintain cohesion in their writings. this study examines how the iraqi writers maintain cohesion in the text by analyzing the various rhetorical moves in azzaman, an online iraqi newspaper. to this purpose, twelve opinion articles from azzaman iraqi newspaper, published from january 2013 to june 2013 were analyzed. the findin...

People engage in multiple types of information-seeking strategies within an information-seeking episode. The objective of this pilot study is to investigate search moves and tactics made by end-users when searching for visual information. The pilot study involves 5 undergraduate students from the Department of Journalism and Media Studies at Rutgers University using the AccuNet/AP Photo Archive...

The paper presents an Adaptive Lattice Model (ALM) based on spatial constraints or resolution such as minimum object size and minimum spatial interval. An ALM represents GIS data by latticing adaptively the spatial space at a certain abstraction level or spatial resolution and omitting all details smaller or finer than the resolution. One implementation of ALM is called CELL, which considers ea...

The existence of several solution strategies for different search and optimisation problems motivates the use of these strategies in a collaborative way. These collaborative approaches are considered in the context of hybridisation. Hyper-heuristics provide hybridisation by performing search on multiple low-level heuristics for finding efficient solutions in a problem-independent manner. In thi...

Two different relay modes are defined in IEEE 802.16j WIMAX standard: transparent mode and non-transparent mode. IEEE 802.16j standard supports mobile station mobility; it defines three kinds of hand over mechanism: hard handover, macro diversity handover (MDHO) and fast BS switching (FBSS) In this paper we have simulated the hard hand over mechanism of IEEE 802.16j transparent mode networks us...

In this paper, we propose a search technique for nurse scheduling, which deals with it as a multi-objective problem. For each nurse, we first randomly generate a set of legal shift patterns which satisfy all shift-related hard constraints. We then employ an adaptive heuristic to quickly find a solution with the least number of violations on the coverage-related hard constraint by assigning one ...
