Bounds for Coding Theory over Rings
Entropy, 2022 Coding theory where the alphabet is identified with the elements of a ring or a module has become an important research topic over the last 30 years. It has been well established that, with the generalization of the algebraic structure to rings, there is

A case of penile strangulation after placement of metallic rings
Urology Annals, 2018 Penile strangulation following placement of metallic rings is a rare clinical entity that needs urgent attention to avoid potentially severe clinical consequences.

Unramified representations of reductive groups over finite rings [PDF]
, 2009 Lusztig has given a construction of certain representations of reductive groups over finite local principal ideal rings of characteristic p, extending the construction of Deligne and Lusztig of representations of reductive groups over finite fields.

Normality in group rings [PDF]
, 2008 Let KG be the group ring of a group G over a commutative ring K with unity. The rings KG are described for which xx(sigma)=x(sigma)x for all x=∑(g∈G)alfa(g)g∈KG, where x↦x(sigma)=∑(g∈G)alfa(g)f(g)sigma(g) is an involution of KG; here f:G→U(K) is a ...

ON THE REFINEMENT OF THE UNIT AND UNITARY CAYLEY GRAPHS OF RINGS [PDF]
Journal of Algebraic Systems, 2019 Let $R$ be a ring (not necessarily commutative) with nonzero identity. We define $Gamma(R)$ to be the graph with vertex set $R$ in which two distinct vertices $x$ and $y$ are adjacent if and only if there exist unit elements $u,v$ of $R$ such that $x+uyv$

Proceedings of the American Mathematical Society, 1964 This paper presents a solution to a popular problem in the subject of rings of analytic functions. In the late 1940's it was shown that two domains Di and D2 in the complex plane were conformally equivalent (to within a certain equivalence relation) iff the rings B(Di) and B(D2) of all bounded analytic functions defined on them were algebraically ...

Dynamic Concentric Rings Infrastructure for Efficient Communications in Wireless Sensor Networks
IEEE Access, 2016 The design of wireless sensor networks (WSNs) has a new paradigm that implies a separation of the underlying communication functionalities from the upper-layer protocols with the goal of leveraging the reusability of protocols.

GROSSLY AND MICROSCOPIC STUDY OF THE TRACHEA AND BRONCHIAL TREE IN THE LOCAL SHEEP ( OVIS ARIS). [PDF]
Basrah Journal of Veterinary Research, 2015 The trachea of the local sheep is a tubular structure that begins at the cricoid cartilage of the larynx and ends when it bifurcates to form the principle bronchi, composed of series of incomplete rings that were incomplete dorsally ...

Plasma electrons above Saturn's main rings: CAPS observations [PDF]
, 2005 We present observations of thermal ( similar to 0.6 - 100eV) electrons observed near Saturn's main rings during Cassini's Saturn Orbit Insertion (SOI) on 1 July 2004. We find that the intensity of electrons is broadly anticorrelated with the ring optical

Branch rings, thinned rings, tree enveloping rings [PDF]
Israel Journal of Mathematics, 2006 We develop the theory of ``branch algebras'', which are infinite-dimensional associative algebras that are isomorphic, up to taking subrings of finite codimension, to a matrix ring over themselves. The main examples come from groups acting on trees. In particular, for every field k we construct a k-algebra K which (1) is finitely generated and infinite-
