Quark Mass Matrix with a Structure of a Rank One Matrix Plus a Unit Matrix [PDF]

, 1995
A quark mass matrix model $M_q=M_e^{1/2} O_q M_e^{1/2} $ is proposed where $M_e^{1/2}={\rm diag}(\sqrt{m_e},\sqrt{m_\mu},\sqrt{m_\tau})$ and $O_q$ is a unit matrix plus a rank one matrix.

Trajectory of left ventricular geometry and diastolic dysfunction in hereditary transthyretin cardiac amyloidosis

ESC Heart Failure, 2021
Amyloid transthyretin (ATTR) depositions cause left ventricular (LV) hypertrophy, diastolic dysfunction, and heart failure. The time course of changes in LV geometry and diastolic dysfunction has not been fully reported in patients with ATTR ...

Quasi Exactly Solvable 2$\times$2 Matrix Equations

, 1993
We investigate the conditions under which systems of two differential eigenvalue equations are quasi exactly solvable. These systems reveal a rich set of algebraic structures. Some of them are explicitely described.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

N $$ \mathcal{N} $$ = 2 JT supergravity and matrix models

Journal of High Energy Physics, 2023
Generalizing previous results for N $$ \mathcal{N} $$ = 0 and N $$ \mathcal{N} $$ = 1, we analyze N $$ \mathcal{N} $$ = 2 JT supergravity on asymptotically AdS2 spaces with arbitrary topology and show that this theory of gravity is dual, in a holographic

Exact 2-point function in Hermitian matrix model

, 2009
J. Harer and D. Zagier have found a strikingly simple generating function for exact (all-genera) 1-point correlators in the Gaussian Hermitian matrix model.

Classical r-matrix of the su(2|2) SYM spin-chain [PDF]

, 2007
In this note we straightforwardly derive and make use of the quantum R-matrix for the su(2|2) SYM spin-chain in the manifest su(1|2)-invariant formulation, which solves the standard quantum Yang-Baxter equation, in order to obtain the correspondent ...

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Effect of the number of filaments on the tensile properties of polyacrylonitrile- and pitch-based carbon fiber epoxy-impregnated bundle composites

Results in Materials, 2023
This study investigated the effect of the number of filaments on the tensile properties of high tensile strength polyacrylonitrile-based (T1000GB) and high modulus pitch-based (K13D) carbon fiber epoxy-impregnated bundle composites.

Matrix models from operators and topological strings, 2

, 2016
The quantization of mirror curves to toric Calabi--Yau threefolds leads to trace class operators, and it has been conjectured that the spectral properties of these operators provide a non-perturbative realization of topological string theory on these ...
