Dynamics and Stability of Black Rings [PDF]
We examine the dynamics of neutral black rings, and identify and analyze a selection of possible instabilities. We find the dominating forces of very thin black rings to be a Newtonian competition between a string-like tension and a centrifugal force. We

Theoretical model for double-skinned concrete-filledsteel-tubular columns with external confinement
Recent advances in the production of super-fine cement and filler technology has made the production of high-strength concrete (HSC) of 120 MPa practicable in the industry.

Tunable Delay Lines in Silicon Photonics: Coupled Resonators and Photonic Crystals, a Comparison
In this paper, we report a direct comparison between coupled resonator optical waveguides (CROWs) and photonic crystal waveguides (PhCWs), which have both been exploited as tunable delay lines.

Branch rings, thinned rings, tree enveloping rings [PDF]
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-

Medieval jewelry at the “Palace Center – East” site in Pliska
This paper presents jewelry falling into two categories, divided by their material composition – a group of metal items, and a group made from glass. They were found during archaeological excavations of the “Palace Center – East” site in Pliska.

Unification Theories: Rings, Boolean Algebras and Yang–Baxter Systems
This paper continues a series of papers on unification constructions. After a short discussion on the Euler’s relation, we introduce a matrix version of the Euler’s relation, E I π+U=O.

Technical elements on the rings in men’s artistic gymnastics—a systematic review [PDF]
Although rings can move freely in all possible directions, by which they differ from all other apparatuses, physical performance at highest level is essetial in men’s artistic gymnastics to fulfill the exercise’s technical requirements in the interest
