High‐Density Topological Defect Array by Two‐Step Interference Photoalignment
Advanced Materials, EarlyView.High density arrays of topological defects in nematic liquid crystal are realized by two‐step interference photoalignment, with a minimal distance of 1.25 micrometer and disclination lines connecting defects on opposing substrates. Such layers can be used as reconfigurable templates for photonic devices to achieve large angle diffraction, beam shaping ...

On commutativity of one-sided s-unital rings
International Journal of Mathematics and Mathematical Sciences, 1992 The following theorem is proved: Let r=r(y)>1, s, and t be non-negative integers. If R is a left s-unital ring satisfies the polynomial identity [xy−xsyrxt,x]=0 for every x,y∈R, then R is commutative. The commutativity of a right s-unital ring satisfying

Artinian Gorenstein algebras with linear resolutions [PDF]
, 2013 Fix a pair of positive integers d and n. We create a ring R and a complex G of R-modules with the following universal property. Let P be a polynomial ring in d variables over a field and let I be a grade d Gorenstein ideal in P which is generated by ...

The universal character ring of some families of one-relator groups
, 2013 We study the universal character ring of some families of one-relator groups. As an application, we calculate the universal character ring of two-generator one-relator groups whose relators are palindrome, and, in particular, of the (-2,2m+1,2n+1 ...

Distributed Bragg Reflector Based on Plasmonic Ag: Plasma Polymer Nanocomposites
Advanced Optical Materials, EarlyView.This paper presents a comprehensive approach for the optical design and validation of silver nanocomposite‐based Distributed Bragg Reflectors (DBRs). It describes deriving material properties (n, k) and using them to predict the performance of the deposited optical stack, as well as to characterize imperfections in the DBR deposition, or even to ...

Another Prüfer Ring of Integer-Valued Polynomials
Journal of Algebra, 1997 Let \(D\) be an integral domain with quotient field \(K\) and let \(\text{ Int}(D) = \{f \in K [x] \mid f(D) \subseteq D\}\). If \(D\) is Dedekind and all its residue fields are finite then \(\text{ Int}(D)\) is Prüfer while if \(\text{ Int}(D)\) is Prüfer then \(D\) is almost Dedekind (i.e.

Versatile Control of Spectral Emissivity in Mid‐Infrared Metasurfaces via Silicon Microstructuring
Advanced Optical Materials, EarlyView.A family of metasurfaces is obtained very simply, solely through the structuration of a single‐crystal silicon surface, without any other material involved. Based on the infrared plasmonic behavior of highly doped silicon, further control of surface topography by micro‐ and nano‐structuration is found to enable an avenue of options toward tailoring its

K-theory for ring C*-algebras - the case of number fields with higher roots of unity
We compute K-theory for ring C*-algebras in the case of higher roots of unity and thereby completely determine the K-theory for ring C*-algebras attached to rings of integers in arbitrary number fields.Comment: 26 pages, final version, accepted for ...
