Gap junction modulation and its implications for heart function

Frontiers in Physiology, 2014
Gap junction communication mediated by connexins is critical for heart function. To gain insight into the causal relationship of molecular mechanisms of disease pathology, it is important to understand which mechanisms contribute to impairment of gap ...

Novel function of Distal-less as a gap gene during spider segmentation. [PDF]

PLoS Genetics, 2011
Despite many aspects of the regulation of segmentation being conserved among arthropods, the evolution of novel gene functions has played an important role in the evolution of developmental regulation and the emergence of new segmental structures ...

Deformation behavior and band gap switching function of 4D printed multi-stable metamaterials

Materials & Design, 2021
Metamaterials/Phononic crystals are used to control the propagation of elastic waves/sound waves, and can be used in fields such as vibration isolation, noise reduction, stealth, focusing, and acoustic wave devices. The realization of real-time, flexible

GAP FUNCTIONS FOR NONSMOOTH EQUILIBRIUM PROBLEMS [PDF]

Taiwanese Journal of Mathematics, 2009
We consider equilibrium problems (EP) with directionally differentiable (not necessarily ${\mathcal C}^1$) bifunctions which are convex with respect to the second variable and we use a gap function approach to solve them. In the first part of the paper we establish a condition under which any stationary point of the gap function solves (EP) and we ...

Antiferromagnetic interactions and the superconducting gap function [PDF]

Physical Review B, 1996
Spin-fluctuation-mediated superconductivity is conventionally associated with d_{x^2-y^2} pairing. We show that a generalized model of antiferromagnetic spin fluctuations in three dimensions may also yield a state with formal ``s-wave'' (A_{1g}) symmetry but with line nodes at k_z \approx \pm π/ 2c.

Convergence Results for History-Dependent Variational Inequalities

Axioms
We consider a history-dependent variational inequality in a real Hilbert space, for which we recall an existence and uniqueness result. We associate this inequality with a gap function, together with two additional problems: a nonlinear equation and a ...

Multi-step prediction of zero series and gap series of Riemann zeta function

Results in Physics, 2021
This paper reveals the chaotic characteristic of the zero-gap series of Riemann zeta function from a new perspective of chaotic dynamics, and addresses the multi-step prediction of the zero series and gap series using the proposed EMD-ELM (empirical mode

Gap Junctions in the Control of Vascular Function [PDF]

Antioxidants & Redox Signaling, 2009
Direct intercellular communication via gap junctions is critical in the control and coordination of vascular function. In the cardiovascular system, gap junctions are made up of one or more of four connexin proteins: Cx37, Cx40, Cx43, and Cx45. The expression of more than one gap-junction protein in the vasculature is not redundant.

Bridging the knowledge gap: from microbiome composition to function

Molecular Systems Biology, 2015
Despite the wealth of metagenomic sequencing data, the functions of most bacterial genes from the mammalian microbiota have remained poorly understood. In their recent study (Yaung et al 2015), Wang, Gerber, and colleagues present a platform which allows

Bloch and Gap Subharmonic Functions

Real Analysis Exchange, 2003
Let \({\mathbb B}_\alpha\) be the class of all positive subharmonic functions \(u\) in the open unit ball \(B_N\) of the space \({\mathbb R}^N\) such that \(G_\alpha (u) = \sup_{x\in B_N} (1-\| x\| ^2)^\alpha u(x) < +\infty.\) The analogous class \({\mathbb A}_\alpha\) of holomorphic in the disc functions \(f\) is defined by the condition \(\sup_{| z ...
