A G2 for science? [PDF]

Science is becoming increasingly globalised. The emerging economic powerhouses, particularly China, are building up their own scientific capabilities rapidly and in a targeted way.

Exact Nonperturbative Unitary Amplitudes for 1->N Transitions

, 1992
I present an extension to arbitrary N of a previously proposed field theoretic model, in which unitary amplitudes for $1->8$ processes were obtained. The Born amplitude in this extension has the behavior $A(1->N)^{tree}\ =\ g^{N-1}\ N!$ expected in a ...

Possible role of human ribonuclease dicer in the regulation of R loops

FEBS Open Bio, EarlyView.
R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible

Distinguished G2-structures on solvmanifolds [PDF]

arXiv, 2018
Among closed G2-structures there are two very distinguished classes: Laplacian solitons and Extremally Ricci-pinched G2-structures. We study the existence problem and explore possible interplays between these concepts in the context of left-invariant G2-structures on solvable Lie groups.

Quadratic closed G2-structures [PDF]

arXiv, 2020
This article studies closed G2-structures satisfying the quadratic condition, a second-order PDE system introduced by Bryant involving a parameter $\lambda.$ For certain special values of $\lambda$ the quadratic condition is equivalent to the Einstein condition for the metric induced by the closed G2-structure (for $\lambda = 1/2$), the extremally ...

On Non Commutative G2 structure

, 2005
Using an algebraic orbifold method, we present non-commutative aspects of $G_2$ structure of seven dimensional real manifolds. We first develop and solve the non commutativity parameter constraint equations defining $G_2$ manifold algebras.

Soman induces endoplasmic reticulum stress and apoptosis of cerebral organoids via the GRP78‐ATF6‐CHOP signaling pathway

FEBS Open Bio, EarlyView.
Cerebral organoids were employed as a novel model to explore the neurotoxicity of soman. Soman inhibited acetylcholinesterase activity, increased cell apoptosis and upregulated endoplasmic reticulum (ER) stress markers glucose‐regulated protein 78 (GRP78), activating transcription factor 6 (ATF6) and C/EBP homologous protein (CHOP).

Hydrogen Measurement & Extraction at Nevada Solar One

SolarPACES Conference Proceedings
Hydrogen was measured and extracted from the headspace gas of four expansion vessels that are components of the heat transfer fluid (HTF) subsystem in the Nevada Solar One (NSO) power plant, Boulder City, Nevada.

p53 controls both the G2/M and the G1 cell cycle checkpoints and mediates reversible growth arrest in human fibroblasts.

Proceedings of the National Academy of Sciences of the United States of America, 1995
Increased expression of wild-type p53 in response to DNA damage arrests cells late in the G1 stage of the cell cycle by stimulating the synthesis of inhibitors of cyclin-dependent kinases, such as p21/WAF1.

M-theory Compactifications on Manifolds with G2 Structure

, 2004
In this paper we study M-theory compactifications on manifolds of G2 structure. By computing the gravitino mass term in four dimensions we derive the general form for the superpotential which appears in such compactifications and show that beside the ...
