Phase-separated Ca and Mg-based nanoparticles in SiO $$_{2}$$ 2 glass investigated by molecular dynamics simulations

Scientific Reports, 2022
The development of new applications based on glass doped with nanoparticles is growing in interest during the last years. The structure and properties of Ca-based silicate nanoparticles formed in situ in a silica matrix through a phase separation ...

Matrix Black Holes [PDF]

, 1997
Four and five dimensional extremal black holes with nonzero entropy have simple presentations in M-theory as gravitational waves bound to configurations of intersecting M-branes.

Nuclear decoupling is part of a rapid protein-level cellular response to high-intensity mechanical loading

Nature Communications, 2019
Cells must be robust to the mechanical demands of their environments. Here, Gilbert et al. expose cells to high-intensity strain cycling and use proteomics to identify a protein, SUN2, that behaves as a strain-induced breakpoint that can decouple the ...

Orbifold Matrix Model [PDF]

, 2002
We study a matrix model describing type IIB superstring in orbifold backgrounds. We particularly consider a {\bf C}^3/{\bf Z}_3 orbifold model whose six dimensional transverse space is orbifolded by {\bf Z}_3 discrete symmetry.

Matrix model holography [PDF]

, 2014
We set up the formalism of holographic renormalization for the matter-coupled two-dimensional maximal supergravity that captures the low-lying fluctuations around the non-conformal D0-brane near-horizon geometry.

Aspects of ALE Matrix Models and Twisted Matrix Strings [PDF]

, 1997
We examine several aspects of the formulation of M(atrix)-Theory on ALE spaces. We argue for the existence of massless vector multiplets in the resolved $A_{n-1}$ spaces, as required by enhanced gauge symmetry in M-Theory, and that these states might ...

Low Rank Matrix-Valued Chernoff Bounds and Approximate Matrix Multiplication [PDF]

, 2010
In this paper we develop algorithms for approximating matrix multiplication with respect to the spectral norm. Let A\in{\RR^{n\times m}} and B\in\RR^{n \times p} be two matrices and \eps>0.

Matrix Metalloproteinases

Current Medicinal Chemistry, 2010
Matrix metalloproteinases (MMPs), also known as matrixins, belong to a group of zinc-dependent proteins, which are thought to play a central role in the breakdown of extracellular matrix. Collagen, elastin, gelatin and casein are major components cleaved by MMPs.
