Learning theories reveal loss of pancreatic electrical connectivity in diabetes as an adaptive response [PDF]
PLoS ONE 8(8): e70366 (2013), 2013 Cells of almost all solid tissues are connected with gap junctions which permit the direct transfer of ions and small molecules, integral to regulating coordinated function in the tissue. The pancreatic islets of Langerhans are responsible for secreting the hormone insulin in response to glucose stimulation.

Characterization of Asymmetric Gap-Engineered Josephson Junctions and 3D Transmon Qubits [PDF]
, 2023 We have fabricated and characterized asymmetric gap-engineered junctions and transmon devices. To create Josephson junctions with asymmetric gaps, Ti was used to proximitize and lower the superconducting gap of the Al counter-electrode. DC IV measurements of these small, proximitized Josephson junctions show a reduced gap and larger excess current for ...

Arrhythmogenic right ventricular cardiomyopathy: considerations from in silico experiments
Frontiers in Physiology, 2012 Objective: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is associated with remodelling of gap junctions and also, although less well-defined, down-regulation of the fast sodium current. The gap junction remodelling and down-regulation of sodium

Connexin’s Connection in Breast Cancer Growth and Progression
International Journal of Cell Biology, 2016 Gap junctions are cell-to-cell junctions that are located in the basolateral surface of two adjoining cells. A gap junction channel is composed of a family of proteins called connexins.

Fabrication of Deep-Sub-Micrometer NbN/AlN/NbN Epitaxial Junctions on a Si Substrate [PDF]
, 2020 We have developed a novel fabrication process for ultra-small, full-epitaxial NbN Josephson junctions on a silicon (Si) substrate. A full-epitaxial NbN/AlN/NbN tri-layer was grown on a Si (100) wafer with a (200)-oriented TiN buffer layer. It was patterned into Josephson junctions by an electron beam lithography (EBL) for junction definition followed ...

Transport across meso-junctions of highly doped Si with different superconductors [PDF]
, 2021 We studied the transport properties of meso-junctions of semiconducting (Sm) highly doped Si with different superconductors (Sc) through point contact Andreev reflection (PCAR) spectroscopy. Spectra of low transparency point contacts between Si and In showed an enhancement in the superconducting energy gap of In.

Single-charge devices with ultrasmall Nb/AlOx/Nb trilayer Josephson junctions [PDF]
J. Appl. Phys. 97, 054501 (2005), 2004 Josephson junction transistors and 50-junction arrays with linear junction dimensions from 200 nm down to 70 nm were fabricated from standard Nb/AlOx/Nb trilayers. The fabrication process includes electron beam lithography, dry etching, anodization, and planarization by chemical-mechanical polishing.

The beneficial effects of cumulus cells and oocyte-cumulus cell gap junctions depends on oocyte maturation and fertilization methods in mice [PDF]
PeerJ, 2016 Cumulus cells are a group of closely associated granulosa cells that surround and nourish oocytes. Previous studies have shown that cumulus cells contribute to oocyte maturation and fertilization through gap junction communication.

Josephson effect in normal and ferromagnetic topological insulator planar, step and edge junctions [PDF]
Phys. Rev. B 90, 045413 (2014), 2014 We investigate Josephson junctions on the surface of a three-dimensional topological insulator in planar, step, and edge geometries. The elliptical nature of the Dirac cone representing the side surface states of the topological insulator results in a scaling factor in the Josephson current in a step junction as compared to the planar junction. In edge
