Propagation of a Solitary Fission Wave

Reaction-diffusion phenomena are encountered in an astonishing array of natural systems. Under the right conditions, self stabilizing reaction waves can arise that will propagate at constant velocity. Numerical studies have shown that fission waves of this type are also possible and that they exhibit soliton like properties. Here, we derive the conditions required for a solitary fission wave to propagate at constant velocity. The results place strict conditions on the shapes of the flux, diffusive, and reactive profiles that would be required for such a phenomenon to persist, and this condition would apply to other reaction diffusion phenomena as well. Numerical simulations are used to confirm the results and show that solitary fission waves fall into a bistable class of reaction diffusion phenomena. (C) 2012 American Institute of Physics.

Housing Analysis for Cleveland Lakefront Development

The Center for Housing Research & Policy conducted this survey and analysis of housing on Cleveland’s lakefront for the Cleveland Lakefront Partners, which is composed of the city of Cleveland, Cleveland Tomorrow, the Greater Cleveland Growth Association, and the Cleveland Neighborhood Development Corporation. The report includes both the results of the survey of residents in the multi-county Cleveland region and a comparative study of waterfront populations in the cities of Milwaukee, Chicago, Portland, and Baltimore. The survey results showed that at least 6,000 and possibly up to 9,000 middle and upper-income households would be interested in living on the lakefront if housing were available. Planners have determined that altering the location and configuration of the city’s Shoreway would make available land that could accommodate 10,000 units of new housing. If five percent (10,000) of Cleveland’s households lived on its lakefront, that percentage would be well within the range of the waterfront populations of comparable cities (Portland, 9.7 percent; Chicago, 7.1 percent; Baltimore, four percent; and Milwaukee, 1.8 percent). The report’s results have played a significant role in the city of Cleveland’s plans for lakefront redevelopment

Gender and Rapid Alterations of Hemispheric Dominance during Planning

Background: Mental planning and carrying out a plan provoke specific cerebral hemodynamic responses. Gender aspects of hemispheric laterality using rapid cerebral hemodynamics have not been reported. Method: Here, we applied functional transcranial Doppler sonography to examine lateralization of cerebral hemodynamics of the middle cerebral arteries of 28 subjects (14 women and 14 men) performing a standard planning task. There were easy and difficult problems, and mental planning without motor activity was separated from movement execution. Results: Difficult mental planning elicited lateralization to the right hemisphere after 2 or more seconds, a feature that was not observed during movement execution. In females, there was a dominance to the left hemisphere during movement execution. Optimized problem solving yielded an increased laterality change to the right during mental planning. Conclusions: Gender-related hemispheric dominance appears to be condition-dependent, and change of laterality to the right may play a role in optimized performance. Results are of relevance when considering laterality from a perspective of performance enhancement of higher cognitive functions, and also of psychiatric disorders with cognitive dysfunctions and abnormal lateralization patterns such as schizophrenia.

Emotional arousal modulates oscillatory correlates of targeted memory reactivation during NREM, but not REM sleep

Rapid eye movement (REM) sleep is considered to preferentially reprocess emotionally arousing memories. We tested this hypothesis by cueing emotional vs. neutral memories during REM and NREM sleep and wakefulness by presenting associated verbal memory cues after learning. Here we show that cueing during NREM sleep significantly improved memory for emotional pictures, while no cueing benefit was observed during REM sleep. On the oscillatory level, successful memory cueing during NREM sleep resulted in significant increases in theta and spindle oscillations with stronger responses for emotional than neutral memories. In contrast during REM sleep, solely cueing of neutral (but not emotional) memories was associated with increases in theta activity. Our results do not support a preferential role of REM sleep for emotional memories, but rather suggest that emotional arousal modulates memory replay and consolidation processes and their oscillatory correlates during NREM sleep
