Ising transition in a one-dimensional quarter-filled electron system with dimerization

open access: yes, 2001
We examine critical properties of the quarter-filled one-dimensional Hubbard model with dimerization and with the onsite and nearest-neighbor Coulomb repulsion U and V.

Structural dynamic modification of vibrating systems [PDF]

open access: yesApplied and Computational Mechanics, 2007
Vibration and acoustic requirements are becoming increasingly important in the design of mechanical structures. The need to vary the structural behaviour to solve noise and vibration problems occurs at design or prototype stage, giving rise to the so ...

The NAD(P)H oxidase homolog Nox4 modulates insulin-stimulated generation of H\u3csub\u3e2\u3c/sub\u3e0\u3csub\u3e2\u3c/sub\u3e and plays an integral role in insulin signal transduction [PDF]

open access: yes, 2004
Insulin stimulation of target cells elicits a burst of H2O2 that enhances tyrosine phosphorylation of the insulin receptor and its cellular substrate proteins as well as distal signaling events in the insulin action cascade.

A six-parameter space to describe galaxy diversification [PDF]

open access: yes, 2012
Galaxy diversification proceeds by transforming events like accretion, interaction or mergers. These explain the formation and evolution of galaxies that can now be described with many observables.

NAD+ Metabolism and Signaling [PDF]

open access: yesCell Metabolism, 2019
We caught up with some of the leading researchers in the NAD+ metabolism and signaling field as they gathered in Dublin for the 2019 FASEB Science Research Conference. Here they share their excitement from the rich history of NAD+ biology dating back over 100 years ago to a future of translation benefiting human health and aging.

Ferroelectric Mott-Hubbard phase in organic conductors

open access: yes, 2003
We present key issues of related phenomenons of the Ferroelectricity and the Charge Disproportionation in organic metals. In (TMTTF_2X the dielectric susceptibility demonstrates clear cases of the ferroelectric and anti-ferroelectric phase transitions ...
