Strong-disorder renormalization-group study of the one-dimensional tight-binding model [PDF]

open access: yes, 2014
We formulate a strong-disorder renormalization-group (SDRG) approach to study the beta function of the tight-binding model in one dimension with both diagonal and off-diagonal disorder for states at the band center.

Directed self-assembly of a xenogeneic vascularized endocrine pancreas for type 1 diabetes

open access: yesNature Communications, 2023
Cell therapy for diabetes requires the combination of bioengineering and new sources of beta cells. Here, the authors report a self-assembly platform based on neonatal pig islets, human endothelial cells and native organ extracellular matrix, which ...

The boundary sine-Gordon theory: classical and semi-classical analysis [PDF]

open access: yes, 1994
We consider the sine-Gordon model on a half-line, with an additional potential term of the form $-M\cos{\beta\over 2}(\varphi-\varphi_0)$ at the boundary. We compute the classical time delay for general values of $M$, $\beta$ and $\varphi_0$ using $\tau$-

In vivo analyses of integrin beta 1 subunit function in fibronectin matrix assembly. [PDF]

open access: yesThe Journal of cell biology, 1990
Early development of the urodele amphibian Pleurodeles waltl is accompanied by a process of progressive fibronectin (FN) fibrillogenesis. FN begins to assemble into fibrils on the inner surface of the blastocoele roof at the early blastula stage and progressively forms a complex extracellular matrix.

Transforming Growth Factor-Beta and Matrix Metalloproteinases: Functional Interactions in Tumor Stroma-Infiltrating Myeloid Cells [PDF]

open access: yesThe Scientific World Journal, 2014
Transforming growth factor-beta (TGF-β) is a pleiotropic factor with several different roles in health and disease. In tumorigenesis, it may act as a protumorigenic factor and have a profound impact on the regulation of the immune system response. Matrix metalloproteinases (MMPs) are a family that comprises more than 25 members, which have recently ...

Spectral Universality of Real Chiral Random Matrix Ensembles

open access: yes, 2000
We investigate the universality of microscopic eigenvalue correlations for Random Matrix Theories with the global symmetries of the QCD partition function.

Accurate ab initio spin densities [PDF]

open access: yes, 2012
We present an approach for the calculation of spin density distributions for molecules that require very large active spaces for a qualitatively correct description of their electronic structure.

Non-perturbative large N trans-series for the Gross–Witten–Wadia beta function

open access: yesPhysics Letters B, 2018
We describe the non-perturbative trans-series, at both weak- and strong-coupling, of the large N approximation to the beta function of the Gross–Witten–Wadia unitary matrix model.

In vivo disruption of TGF-beta signaling by Smad7 in airway epithelium alleviates allergic asthma but aggravates lung carcinogenesis in mouse. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: TGF-beta has been postulated to play an important role in the maintenance of epithelial homeostasis and the development of epithelium-derived cancers.

Exact Expressions for Kullback–Leibler Divergence for Multivariate and Matrix-Variate Distributions

open access: yesEntropy
The Kullback–Leibler divergence is a measure of the divergence between two probability distributions, often used in statistics and information theory. However, exact expressions for it are not known for multivariate or matrix-variate distributions apart ...
