Matrix Gegenbauer Polynomials: the $2\times 2$ Fundamental Cases [PDF]

open access: yes, 2015
In this paper, we exhibit explicitly a sequence of $2\times2$ matrix valued orthogonal polynomials with respect to a weight $W_{p,n}$, for any pair of real numbers $p$ and $n$ such that ...

Tenascin-C induces prolonged constriction of cerebral arteries in rats

open access: yesNeurobiology of Disease, 2013
Tenascin-C (TNC), a matricellular protein, is induced in association with cerebral vasospasm after subarachnoid hemorrhage. The aim of this study was to assess the vasoconstrictive effects of TNC and its mechanisms of action on cerebral arteries in vivo.

Exact Results in N_c=2 IIB Matrix Model [PDF]

open access: yes, 1997
We investigate N_c=2 case of IIB matrix model, which is exactly soluble. We calculate the partition function exactly and obtain a finite result without introducing any cut-off.

Human pluripotent stem cells in contemporary medicine

open access: yesИсследования и практика в медицине, 2015
Human pluripotent stem cells (hPSCs) are capable of indefinite proliferation and can be differentiated into any cell type of the human body. Therefore, they are a promising source of cells for treatment of numerous degenerative diseases and injuries ...

Culture time of vitrified/warmed zygotes before microinjection affects the production efficiency of CRISPR-Cas9-mediated knock-in mice

open access: yesBiology Open, 2017
Robust reproductive engineering techniques are required for the efficient and rapid production of genetically modified mice. We have reported the efficient production of genome-edited mice using reproductive engineering techniques, such as ultra ...

Quantum spin-Hall effect and topologically invariant Chern numbers. [PDF]

open access: yesPhysical Review Letters, 2006
We present a topological description of the quantum spin-Hall effect (QSHE) in a two-dimensional electron system on a honeycomb lattice with both intrinsic and Rashba spin-orbit couplings.

Logging evaluation methods of low-organic matter fault-block shale oil in the Subei Basin and their application [PDF]

open access: yesYouqicang pingjia yu kaifa
The Subei Basin is characterized by a complex structure and well-developed faults. The shale in the second member of the Funing Formation has relatively low organic matter abundance, with a total organic carbon (TOC) generally below 1.5%.

Matrix model for noncommutative gravity and gravitational instantons [PDF]

open access: yes, 2003
We introduce a matrix model for noncommutative gravity, based on the gauge group $U(2) \otimes U(2)$. The vierbein is encoded in a matrix $Y_{\mu}$, having values in the coset space $U(4)/ (U(2) \otimes U(2))$, while the spin connection is encoded in a ...

Symmetric 2×2 matrix functions with order preserving property [PDF]

open access: yesOpuscula Mathematica
It is known that the discrete matrix Riccati equation has the order preserving property under some assumptions. In this paper we formulate and prove the converse statement for the case when the dimensions of the matrices are \(2 \times 2\) and the order ...
