ECM-enriched alginate hydrogels for bioartificial pancreas: an ideal niche to improve insulin secretion and diabetic glucose profile

open access: yesJournal of Applied Biomaterials & Functional Materials, 2019
Introduction: The success of a bioartificial pancreas crucially depends on ameliorating encapsulated beta cells survival and function. By mimicking the cellular in vivo niche, the aim of this study was to develop a novel model for beta cells ...

Adhesion of a chicken myeloblast cell line to fibrinogen and vitronectin through a beta 1-class integrin. [PDF]

open access: yes, 1992
The adhesive interactions of circulating blood cells are tightly regulated, receptor-mediated events. To establish a model for studies on regulation of cell adhesion, we have examined the adhesive properties of the HD11 chick myeloblast cell line ...

Beta-ensembles for toric orbifold partition function

open access: yes, 2011
We investigate combinatorics of the instanton partition function for the generic four dimensional toric orbifolds. It is shown that the orbifold projection can be implemented by taking the inhomogeneous root of unity limit of the q-deformed partition ...

Matrix transformations of Norlund–Orlicz difference sequence spaces of nonabsolute type and their Toeplitz duals

open access: yesAdvances in Difference Equations, 2020
In this paper, the Nörlund–Orlicz difference sequence space N t ( F , Δ n m , u , q ) $\mathcal{N}^{t}(\mathcal{F},\Delta^{m}_{n},u,q)$ of nonabsolute type is introduced as a domain of Nörlund means which is isomorphic to the space ℓ ( p ) $\ell(p)$ and ...

Symmetries of WDVV equations

open access: yes, 2005
We say that a function F(tau) obeys WDVV equations, if for a given invertible symmetric matrix eta^{alpha beta} and all tau \in T \subset R^n, the expressions c^{alpha}_{beta gamma}(tau) = eta^{alpha lambda} c_{lambda beta gamma}(tau) = eta^{alpha lambda}

Self-dual noncommutative \phi^4-theory in four dimensions is a non-perturbatively solvable and non-trivial quantum field theory

open access: yes, 2013
We study quartic matrix models with partition function Z[E,J]=\int dM \exp(trace(JM-EM^2-(\lambda/4)M^4)). The integral is over the space of Hermitean NxN-matrices, the external matrix E encodes the dynamics, \lambda>0 is a scalar coupling constant and ...

Operator mixing in massless QCD-like theories and Poincarè–Dulac theorem

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
Recently, a differential-geometric approach to operator mixing in massless QCD-like theories – that involves canonical forms, obtained by means of gauge transformations, based on the Poincarè–Dulac theorem for the system of linear differential equations ...

Autocorrelations of the characteristic polynomial of a random matrix under microscopic scaling [PDF]

open access: yes, 2010
We calculate the autocorrelation function for the characteristic polynomial of a random matrix in the microscopic scaling regime. While results fitting this description have be proved before, we will cover all values of inverse temperature $\beta \in (0,\

The density of eigenvalues seen from the soft edge of random matrices in the Gaussian beta-ensembles

open access: yes, 2014
We characterize the phenomenon of "crowding" near the largest eigenvalue $\lambda_{\max}$ of random $N \times N$ matrices belonging to the Gaussian $\beta$-ensemble of random matrix theory, including in particular the Gaussian orthogonal ($\beta=1 ...
