Chi-Square Approximation for the Distribution of Individual Eigenvalues of a Singular Wishart Matrix

Mathematics
This paper discusses the approximate distributions of eigenvalues of a singular Wishart matrix. We give the approximate joint density of eigenvalues by Laplace approximation for the hypergeometric functions of matrix arguments.

Brain Pericytes and Wnt/β‐Catenin Signaling Induce Functional Blood–Brain Barrier Phenotype in Human iPSC‐Derived Model

Small Methods, EarlyView.
This study shows that human iPSC‐derived endothelial cells acquire a functional blood–brain barrier phenotype when co‐cultured with brain pericytes and stimulated with CHIR‐99021, a Wnt/β‐catenin activator. This model recapitulates key barrier properties, inflammatory responses, and transcriptomic features of the native human BBB, offering new ...

Dielectric Response of Large Band Gap Cyclic Olefines With Symmetric and Asymmetric Pendant Polar Groups

High Voltage, EarlyView.
ABSTRACT The dielectric response of two typical polyoxafluoronorbornene with asymmetric and symmetric pendant polar groups is investigated to better understand the impact of the polymer structure on dielectric properties. Based on the Dissado–Hill modelling of broadband dielectric response, the contribution of the bicyclic backbone and fluorinated ...

Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

Integrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Distribution evaluation of hypergeometric series

, 2020
We evaluate several classes of high weight hypergeometric series via Gamma, polylogarithm and elliptic integrals, mainly through distribution relations.

Cellular Stress, Inflammation and Barrier Damage in Gut Epithelial Cells Caused by Aspartame

Allergy, EarlyView.
This study shows that aspartame, at dietary‐relevant doses, induces cytotoxicity, cellular distress associated with endoplasmic reticulum stress, oxidative stress, DNA replication and repair mechanism disturbance culminating in epithelial barrier damage.

PHGDH Orchestrates Cell Cycle Progression to Drive Cardiomyocyte Proliferation and Myocardial Regeneration via TGF‐β/Smad Signalling Pathway

Cell Proliferation, EarlyView.
PHGDH promoted cardiomyocyte proliferation and myocardial regeneration via cell cycle and TGF‐β/Smad signalling pathways during cardiac repair. Moreover, PHGDH benefits cardiac repair and cardiomyocyte proliferation in mammalian mice following MI. ABSTRACT The mature mammalian heart has limited ability for self‐repair and regeneration.

Do temporary changes in earnings caused by mean reversion affect firms’ refinancing decisions?

Journal of Financial Research, EarlyView.
Abstract We develop a dynamic two‐stage trade‐off model with refinancing when earnings are mean reverting. Our model predicts a negative relation between profitability and leverage at refinancing due to conservative debt increases. With multiple rounds of refinancing, the leverage–profitability relation may turn positive when firms have substantial ...

Change Within Stability: A Mixed‐Methods Study of Identity Development in Established Adulthood

Journal of Personality, EarlyView.
ABSTRACT Introduction Longitudinal studies examining identity development in adulthood are scarce, and little is known about the processes through which a stable identity is maintained or revised. This study addresses these gaps by examining (a) longitudinal patterns of identity status development from emerging through established adulthood and (b ...
