Crystal structure of O-benzyl-l-tyrosine N-carboxy anhydride
Acta Crystallographica Section E: Crystallographic Communications, 2017 In the title compound, C17H15NO4 (alternative name; O-benzyl-l-tyrosine N-carboxy anhydride), the oxazolidine ring is planer, with an r.m.s. deviation of 0.039 Å. The benzyloxy and benzyl rings are almost coplanar, making a dihedral angle of 0.078 (10)°,

A note on Jordan left *-centralizers on prime and semiprime rings with involution
Journal of Taibah University for Science, 2017 The aim of this note is to give alternative and short proofs for some results to Ali et al. in [3] by using the relationship between the concepts of Jordan left *-centralizer and right centralizer on a 2-torsion free semiprime rings endowed with ...

Leavitt path algebras: Graded direct-finiteness and graded $\Sigma$-injective simple modules
, 2017 In this paper, we give a complete characterization of Leavitt path algebras which are graded $\Sigma $-$V$ rings, that is, rings over which a direct sum of arbitrary copies of any graded simple module is graded injective.

Diamagnetic orbital response of mesoscopic silver rings
, 2002 We report measurements of the flux-dependent orbital magnetic susceptibility of an ensemble of 10^5 disconnected silver rings at 217 MHz. Because of the strong spin-orbit scattering rate in silver this experiment is a test of existing theories on orbital

, 2010 In this paper we study the notion of Smarandache loops. We obtain some interesting results about them. The notion of Smarandache semigroups homomorphism is studied as well in this paper.

Journal of High Energy Physics, 2018 We study the extremal correlation functions of (twisted) chiral ring operators via superlocalization in N = 2 , 2 $$ \mathcal{N}=\left(2,\ 2\right) $$ superconformal field theories (SCFTs) with central charge c ≥ 3, especially for SCFTs with Calabi-Yau ...

On Certain Divisibility Property of Polynomials [PDF]
, 2010 We review the definition of D-rings introduced by H. Gunji & D. L. MacQuillan. We provide an alternative characterization for such rings that allows us to give an elementary proof of that a ring of algebraic integers is a D-ring.

An alternative origin for debris rings of planetesimals
, 2012 Core Accretion, the most widely accepted scenario for planet formation, postulates existence of km-sized solid bodies, called planetesimals, arranged in a razor-thin disc in the earliest phases of planet formation.

A search for concentric rings with unusual variance in the 7-year WMAP temperature maps using a fast convolution approach [PDF]
, 2013 We present a method for the computation of the variance of cosmic microwave background (CMB) temperature maps on azimuthally symmetric patches using a fast convolution approach.
