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 ...

Matrix elements and duality for type 2 unitary representations of the Lie superalgebra gl(m|n) [PDF]

open access: yes, 2015
The characteristic identity formalism discussed in our recent articles is further utilized to derive matrix elements of type 2 unitary irreducible $gl(m|n)$ modules. In particular, we give matrix element formulae for all gl(m|n) generators, including the

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 ...

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%.

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 ...

Efficient gene delivery to photoreceptors using AAV2/rh10 and rescue of the Rho−/− mouse

open access: yesMolecular Therapy: Methods & Clinical Development, 2015
As gene therapies for various forms of retinal degeneration progress toward human clinical trial, it will be essential to have a repertoire of safe and efficient vectors for gene delivery to the target cells.

Negative clean rings

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022
A ring is called negative clean if the negative (i.e., the additive inverse) of each clean element is also clean. Clean rings are negative clean.
