A large, shallow braided river delta sedimentary system developed in the Yanchang Formation during the Triassic in the southwest of the Ordos basin. In this braided delta system, abundant oil and gas resources have been observed, and the area is a hotspot for oil and gas resource exploration. Through extensive field work on outcrops and cores and analyses of geophysical data, it was determined ...

We define a new homotopy algebraic structure, that we call braided $L_\infty$-algebra, and use it to systematically construct class of noncommutative field theories, theories. Braided theories have gauge symmetries which realize Lie algebra, whose Noether identities are inhomogeneous extensions the classical identities, do not act on solutions equations. Drinfel'd twist deformation quantization...

Constructive reuse (versus degradation) of plant biomass residuals with braided twine, rope, hammocks, baskets, etc.

Braided composites have been used widely in many engineering fields where the high mechanical characteristics and light weight properties were important. In order to estimate the mechanical characteristics of the braided composites, the numerical technique is very effective to reduce the testing and production costs. However, if the architecture of fiber bundle is more complex such as 3-D braid...

OBJECTIVE Constriction of vein grafts with braided external nitinol meshes had previously led to the successful elimination of neointimal tissue formation. We investigated whether pulse compliance, smaller kink-free bending radius, and milder medial atrophy can be achieved by knitting the meshes rather than braiding, without losing the suppressive effect on intimal hyperplasia. METHODS Pulse ...

Most tubes have seams (intercellular or autocellular junctions that seal membranes together into a tube), but "seamless" tubes also exist. In Drosophila, stellate-shaped tracheal terminal cells make seamless tubes, with single branches running through each of dozens of cellular extensions. We find that mutations in braided impair terminal cell branching and cause formation of seamless tube cyst...

1 : We investigate invertible elements and gradings in braided tensor categories. This leads us to the definition of theta-, product-, subgrading and orbitcategories in order to construct new families of BTC’s from given ones. We use the representation theory of Hecke algebras in order to relate the fusionring of a BTC generated by an object X with a two component decomposition of its tensorsqu...

We present and study two families of polynomials with coefficients in the center of the universal enveloping algebra. These polynomials are analogues of a determinant and a characteristic polynomial of a certain non-commutative matrix, labeled by irreducible representations of gl n (C). The matrix is an image of the universal R-matrix of a Yangian of gl n (C) under certain representation. We co...

With any even Hecke symmetry R (that is a Hecke type solution of the Yang-Baxter equation) we associate a quasitensor category. We formulate a condition on R implying that the constructed category is rigid and its commutativity isomorphisms RU,V are natural in the sense of [T]. We show that this condition leads to rescaling the initial Hecke symmetry. We suggest a new way of introducing traces ...
