The concept of "random loose packing" (RLP) has evolved through extensive study of loose packings of spheres, which has resulted in an accepted definition as the loosest packing that can be obtained by pouring grains. We extend this consideration to packings of nonspherical grains (ellipsoids) formed by slow settling in a viscous liquid, and perform a detailed analysis of the structural propert...

We consider the problem of minimizing a functional (like the area, perimeter, surface) within the class of convex bodies whose support functions are trigonometric polynomials. The convexity constraint is transformed via the Fejér-Riesz theorem on positive trigonometric polynomials into a semidefinite programming problem. Several problems such as the minimization of the area in the class of cons...

Intracellular bodies consisting of dynamic aggregates of concentrated proteins and often RNA are a ubiquitous feature of the cytoplasm and nucleus of living cells. Dozens of different types of protein bodies are involved in diverse physiological processes including ribosome biogenesis, RNA splicing, and cell division. Unlike conventional organelles, they are not defined by an enclosing membrane...

Nuclei of human neurilemoma cells exhibit deep and extensive invaginations of part of their surface. Such invaginations contain cytoplasmic matter. However, in areas of the nucleoplasm distant from the invaginations, small membrane-bound bodies, some of which contain a "nucleoid," occur either singly or grouped together and enclosed within a large membrane body. These small bodies are not consi...

There is substantial interest in controlling a group of bodies from specifications of tasks given in a high-level, human-like language. This paper proposes a methodology that creates low-level hybrid controllers that guarantee that a group of bodies execute a high-level specified task without dynamical system modeling, precise state estimation or state feedback. We do this by exploiting the wil...

In order to test the developmental potential of the mouse embryonic-stem-cell-derived embryoid bodies as chorioallantoic grafts, the embryoid bodies were transplanted to the chorioallantoic membrane (CAM) of the chick embryo. The graft implantation was achieved if the embryoid bodies were transferred to the CAM into the blood drop created by gentle laceration of a CAM blood vessel. The resultin...

It is Quigley’s view that we should regard our own human bodies as our property. Wittgenstein’s famous comments about games and family resemblances are cited in support of this contention. She thinks that classification of bodies as property is significant and that it will help us to answer the ethical and political questions about how we should treat and be permitted to treat body parts, tissu...

the criminal justice and observance of human rights principles have important roles in efficiency of bodies involved in combating against terrorism. as some states like u.k. have violated several international provisions such as international civil and political covenant and the european convention of human rights, this article tries to verify anti-terrorism crime and security act (atcsa) and i...
