Universal random matrix correlations of ratios of characteristic polynomials at the spectral edges

open access: yes, 2003
It has been shown recently by Fyodorov and Strahov [math-ph/0204051] that Cauchy transforms of orthogonal polynomials appear naturally in general correlation functions containing ratios of characteristic polynomials of random N×N Hermitian matrices.

Norms of positive definite toeplitz matrices and detection of almost periodic components in random signals [PDF]

open access: yes, 2014
For positive definite Toeplitz matrices generated by trigonometric moments of a non-negative measure we note that the Hilbert-Schmidt norm and the maximal eigenvalue satisfy certain limiting relations.

Analysis on the Empirical Spectral Distribution of Large Sample Covariance Matrix and Applications for Large Antenna Array Processing

open access: yesIEEE Access, 2019
This paper addresses the asymptotic behavior of a particular type of information-plus-noise-type matrices, where the column and row numbers of the matrices are large and of the same order, while signals have diverged and the time delays of the channel ...

Early‐life high‐fat diet exposure increases Achilles tendon stiffness and induces transcriptomic alterations

open access: yesFEBS Open Bio, EarlyView.
Early‐life exposure to a high‐fat diet altered intact Achilles tendons in rat offspring, making them thinner, stiffer, and molecularly distinct even without injury. These findings suggest that developmental high‐fat diet exposure may impair tendon quality and increase susceptibility to mechanical overload or tendon injury later in life.

Time‐restricted feeding prior to Mycobacterium tuberculosis infection reduces tissue CD4+ T cells with limited impact on bacterial clearance

open access: yesFEBS Open Bio, EarlyView.
Time‐restricted feeding (TRF) in mice increased liver fatty acid oxidation and decreased fatty acid biosynthesis. These alterations persisted when TRF was discontinued and the host was infected with Mycobacterium tuberculosis. Pre‐exposure to TRF did not alter tissue (lung and spleen) mycobacterial burden but significantly reduced CD3+ T cells in lungs

Integrable structure of Ginibre's ensemble of real random matrices and a Pfaffian integration theorem

open access: yes, 2007
In the recent publication [E. Kanzieper and G. Akemann, Phys. Rev. Lett. 95, 230201 (2005)], an exact solution was reported for the probability p_{n,k} to find exactly k real eigenvalues in the spectrum of an nxn real asymmetric matrix drawn at random ...

Probability of Two Large Gaps in the Bulk and at the Edge of the Spectrum of Random Matrices

open access: yes, 2022
We present the probability of two large gaps (intervals without eigenvalues) in the bulk and also in the edge scaling limit of the Gaussian Unitary Ensemble of random ...

Cyclic azapeptide CD36 ligand attenuates cardiac injury and reduces long‐chain fatty acid accumulation after myocardial ischemia–reperfusion in mice

open access: yesFEBS Open Bio, EarlyView.
In a murine model of myocardial ischemia and reperfusion (MI/R), the CD36 azapeptide ligand MPE‐298 reduces cardiac injury and transiently lowers left ventricular long‐chain fatty acids (LCFAs) accumulation 3 h after reperfusion, accompanied by a decrease of oxidative stress and inflammation‐associated genes' expression in the heart and adipose tissue.

Algorithm for Constructing Compound Partial Random Measurement Matrices Based on Multidimensional Chaotic Mapping

open access: yesShuju Caiji Yu Chuli
The construction of the measurement matrix is a crucial factor influencing the reconstruction performance of compressive sensing techniques. To address the high storage cost of random measurement matrices and the difficulty in satisfying the restricted ...

Hydrostatic pressure activates HIF‐1α via β‐catenin to promote stemness in breast cancer cells

open access: yesFEBS Open Bio, EarlyView.
To mimic the elevated intestinal fluid pressure in breast cancers, we loaded human breast cancer cells (MCF‐7, MDA‐MB‐453, and BT‐474) to 50 mmHg hydrostatic pressure. Hydrostatic pressure exposure upregulated HIF‐1α and induced stemness in MCF‐7 and BT‐474 cells.
