The twisted plywood architecture, known as the Bouligand structure, is a ubiquitous biological and synthetic fibrous composite structure, analogous to that of cholesteric liquid crystals. Twisted plywoods can show ideal or non-ideal structures and are formed via equilibrium or non-equilibrium liquid crystal self-assembly processes. A key to the structure characterisation of plywood films is the...

arthritis refers to different medical conditions associated with disorder of the primary structures that determine joint functions such as bones, cartilage and synovial membranes. drug discovery and delivery to retard the degeneration of joint tissues are challenging. current treatments of different arthritis involves administration of ideal non-steroidal anti-inflammatory drugs (nsaids) but ar...

In this study, nonlinear vibration of axially moving strings in thermal environment is investigated. The vibration haracteristics of the system such as natural frequencies, time domain response and stability states are studied at different temperatures. The velocity of the axial movement is assumed to be constant with minor harmonic variations. It is presumed that the system and the environment...

using the notion of “belongingness ($epsilon$)” and “quasi-coincidence (q)” of fuzzy points with fuzzy sets, we introduce the concept of an ($ alpha, beta$)- fuzzyhv-ideal of an hv-ring, where , are any two of {$epsilon$, q,$epsilon$ $vee$ q, $epsilon$ $wedge$ q} with $ alpha$ $neq$ $epsilon$ $wedge$ q. since the concept of ($epsilon$, $epsilon$ $vee$ q)-fuzzy hv-ideals is an important and ...

Formal epistemologists often claim that our credences should be representable by a probability function. Complete probabilistic coherence, however, is only possible for ideal agents, raising the question of how this requirement relates to everyday judgments concerning rationality. One answer being rational contextual matter, standards rationality change along with situation. Just like who count...

We give a unified description of tetrahedra with lightlike faces in 3d anti-de Sitter, de Sitter and Minkowski spaces their duals hyperbolic half-pipe spaces. show that both types are determined by generalized cross-ratio values commutative 2d real algebra generalizes the complex numbers. Equivalently, pair edge lengths dihedral angles. prove dual precisely ideal introduced Danciger. Finally, w...
