Generalized recoupling coefficients or 3nj-coefficients can be expressed as multiple sums over products of Racah or 6j-coefficients [1]. The problem of finding an optimal summation formula (i.e. with a minimal number of Racah coefficients) for a given 3nj-coefficient is equivalent to finding an optimal reduction of a so-called Yutsis graph [2]. In terms of graph theory Yutsis graphs are connect...

Composite quantum materials are the ideal examples of multifunctional systems which simultaneously host more than one novel phenomenon in physics. Here, we present a combined theoretical and experimental study to demonstrate presence an extremely large exchange bias range 0.8 T - 2.7 fully compensated magnetic state (FCF) special type Pt Ni doped Mn$_3$In cubic alloy. oppositely aligned uncompe...

Lipid bicontinuous cubic phases have attracted enormous interest as bio-compatible scaffolds for use in a wide range of applications including membrane protein crystallisation, drug delivery and biosensing. One of the major bottlenecks that has hindered exploitation of these structures is an inability to create targeted highly swollen bicontinuous cubic structures with large and tunable pore si...

Assembly of mesostructured silica using Pluronic P123 triblock copolymer (EO(20)-PO(70)-EO(20)) and n-butanol mixture is a facile synthesis route to the MCM-48-like ordered large mesoporous silicas with the cubic Iad mesostructure. The cubic phase domain is remarkably extended by controlling the amounts of butanol and silica source correspondingly. The extended phase domain allows synthesis of ...

Calculations using first principles methods and strong coupling theory are carried out to understand the electronic structure and superconductivity in cubic and tetragonal TiH2. A large electronic density of states at the Fermi level in the cubic phase arises from Ti-t2g states and leads to a structural instability towards tetragonal distortion at low temperatures. However, constraining the in-...

Colonic polyps are growths on the inner wall of the colon. They appear like elliptical protrusions which can be detected by curvature-derived shape discriminators. For reasons of computation efficiency, much of the past work in computeraided diagnostic CT colonography adopted kernel-based convolution methods in curvature estimation. However, kernel methods can yield erroneous results at thin st...

This thesis provides strong evidence that the quartet distance between two general trees is practically computable in sub-cubic time. The thesis comprises a detailed study of three algorithms for quartet distance computation between trees of arbitrary degree; a quartic, a cubic and a sub-cubic time algorithm. A common property to these three algorithms is that they all have a time complexity th...

We are writing this paper as a response to a paper appeared in PFLDnet 2007 authored by Leith et al. on the analysis of CUBIC [1] (hereafter called LSM). There are a few debatable issues that might mislead readers about the behavior of CUBIC. In general, the authors presented their observations on the performance of CUBIC under a special set of testing environments. However, as this paper is ab...
