We study the phase behavior of bowl-shaped particles using computer simulations. These particles were found experimentally to form a metastable wormlike fluid phase in which the bowl-shaped particles have a strong tendency to stack on top of each other [M. Marechal, Nano Lett. 10, 1907 (2010)]. In this work, we show that the transition from the low-density fluid to the wormlike phase has an int...

Underactuated manipulation is the process of controlling several object degrees-of-freedom with fewer robot actuators. Underactuated manipulation allows us to build dexterous robots with only a few actuators. In this paper we explore the possibility of useful dynamic manipulation with only a single actuator. Our case study is a ball rolling in an asymmetrical bowl which can be accelerated along...

The mechanism by which renal prostaglandins stimulate renin secretion in vivo is unknown. In this in vitro study we measured the effects of activation of the prostaglandin (PG) system on renin release from slices of rabbit renal cortex. The PG precursor arachidonic acid (C20:4), a natural PG endoperoxide (PGG2), two stable synthetic PG endoperoxide analogues (EPA I and II), PGE2, PGF2alpha, and...

In this paper, we classify all noncollapsed singularity models for the mean curvature flow of 3-dimensional hypersurfaces in $\mathbb{R}^4$ or more generally $4$-manifolds. Specifically, prove that every translating hypersurface is either $\mathbb{R}\times$2d-bowl, a 3d round bowl, belongs to one-parameter family oval bowls constructed by Hoffman-Ilmanen-Martin-White.

The composition of fatty acids determines the flavor and quality meat. Flavor compounds are generated during cooking process by decomposition volatile via lipid oxidation. A number research on candidate genes related to acid content in livestock species have been published. majority these studies focused pigs cattle; association between meat chickens has rarely reported. Therefore, this study i...

In the title compound, C(31)H(7)BF(12)N(6)O, mol-ecules are arranged into one-dimensional columns with an inter-molecular B⋯B distance of 5.3176 (8) Å. Bowl-shaped mol-ecules are arranged within the columns in a concave bowl-to-ligand arrangement separated by a ring centroid distance of 3.532 (2) Å between the benzene ring of the 4-methyl-phen-oxy ligand and one of the three five-membered rings...

A model of cooperation versus defection in a sequence of games is analysed under the assumptions that the rules of the game are randomly changed from one encounter to another, that the decisions are to be made each time anew, according to the (random) rules of the specific local game, and that the result of one such game affects the ability of a player to participate and thus, cooperate in the ...
