Energy consumption and design simplicity are paramount concerns in on-chip interconnects for chip multiprocessors. Several proposed and a few implemented many-core on-chip interconnects are mesh or torus-based. These designs offer good scalability. However, most mainstream commercial chip multiprocessors use rings, in which each network node has relatively simpler ring stop logic. Network traff...

We investigate the effect of anisotropic elastic energy on defect patterns of liquid crystals confined in a three-dimensional spherical domain within the framework of Landau–de Gennes model. Two typical strong anchoring boundary conditions, namely homeotropic and mirror-homeotropic anchoring conditions, are considered. For the homeotropic anchoring, we find three different configurations: uniax...

The ATP-dependent caseinolytic protease (Clp) is an essential housekeeping enzyme in plant chloroplasts. It is by far the most complex of all known Clp proteases, with a proteolytic core consisting of multiple catalytic ClpP and noncatalytic ClpR subunits. It also includes a unique form of Clp protein of unknown function designated ClpT, two of which exist in the model species Arabidopsis thali...

Radical ring-opening copolymerization-induced self-assembly (rROPISA) was successfully applied to the synthesis of core-, surface- or surface plus core-degradable nanoparticles in heptane, leading site-specific degradability by rROPISA.

The C8'-epimeric pyranosyl amino acid core 2 of amipurimycin was synthesized from D-glucose derived alcohol 3 in 13 steps and 14% overall yield. Thus, the Sharpless asymmetric epoxidation of allyl alcohol 7 followed by trimethyl borate mediated regio-selective oxirane ring opening with azide, afforded azido diol 10. The acid-catalyzed 1,2-acetonide ring opening in 10 concomitantly led to the fo...

in this paper, we study some ring theoretic properties of the amalgamated duplication ring $rbowtie i$ of a commutative noetherian ring $r$ along an ideal $i$ of $r$ which was introduced by d'anna and fontana. indeed, it is determined that when $rbowtie i$ satisfies serre's conditions $(r_n)$ and $(s_n)$, and when is a normal ring, a generalized cohen-macaulay ring and finally a filter ring.

Cassini images of Saturn's small inner satellites (radii of less than approximately 100 kilometers) have yielded their sizes, shapes, and in some cases, topographies and mean densities. This information and numerical N-body simulations of accretionary growth have provided clues to their internal structures and origins. The innermost ring-region satellites have likely grown to the maximum sizes ...

The linear stability of thin vortex rings are studied by short-wavelength stability analysis. The modified Hill–Schrödinger equation for vortex rings, which incorporates curvature effect, is derived. It is used to evaluate growth rates analytically. The growth rates are also evaluated by numerical calculation and they agree well with analytical values for small e which is the ratio of core radi...

1, 3-Benzodioxole ring system present in various naturally occurring molecules. Various synthetic molecules having 1, 3-Benzodioxole ring system have shown various biological activities. Stiripentol and Antiepilepserine are recently developed antiepileptic drugs which contain 1, 3-Benzodioxle rings system in core moiety. In the present work I have focused on the anticonvulsant activity of 1, 3B...

Since the time of the Voyager flybys of Saturn in 1980-1981, Saturn's eccentric F ring has been known to be accompanied on either side by faint strands of material. New Cassini observations show that these strands, initially interpreted as concentric ring segments, are in fact connected and form a single one-arm trailing spiral winding at least three times around Saturn. The spiral rotates arou...
