We propose a new selection principle for distinguishing among possible vacua that we call the "relaxation principle." The idea is that the Universe will naturally select among possible vacua through its cosmological evolution, and the configuration with the biggest filling fraction is the likeliest. We apply this idea to the question of the number of dimensions of space. We show that under conv...

Most things in biology spread out into three dimensions, and many biological web sites include three-dimensional images. But biologists want more than a look at something. They want to pick it up and look at it from all sides, which is where three-dimensional images that can be manipulated online really come into their own. One approach to such interactive images relies on VRML (virtual reality...

We present the results of 3-dimensional simulations of the direct collapse to a black hole of a rotating, 60M⊙, zero metallicity, population III star. Because the structure of this star (angular momentum, density and temperature profiles) is similar to many collapsar gamma-ray burst progenitors, these calculations have implications beyond the fate of population III stars. These simulations prov...

I have had only few major ‘‘eureka’’ moments in my life. One of them was when I realised the difference between ordinary linear thinking and systems thinking. Since then I have spent quite a lot of my time teaching systems thinking in one form or another to doctors, psychologists, educators and others. Sometimes people can be turned off by the word systems because it sounds so mechanical, but o...

in this paper the interior noise level of a vehicle due to structural vibration, named structure borne noise, as a part of nvh analysis has been investigated. first structural analysis is performed and vibrational behavior of structure carried out due to power plant excitations. then interior acoustic cavity response for such excitation and resultant noise is determined. vibrational analysis is...

OBJECTIVES Neglect in vertical and radial directions is rarely evaluated systematically in patients with brain damage. METHOD AND RESULTS Using the line bisection task, we confirmed that some patients with unilateral brain damage manifest vertical or radial spatial neglect. In fact, patients with severe left horizontal neglect tend to have severe vertical neglect. CONCLUSION Because vertica...

Three Dimensions of Scheduling by Frank Bellosa The research presented in this dissertation has concentrated on the gathering and usage of memory access patterns in the area of user-level as well as kernel-level scheduling, yet covering both time-sharing and real-time aspects. Beside the questions when a task has to be executed and which CPU should be used, the freedom of scheduling is enlarged...
