Generation Alpha

Varying Alpha, Mass Generation and Extra Dimensions

We consider variation of coupling strengths and mass ratios in and beyond the Standard Model, in the light of various mechanisms of mass generation. In fourdimensional unified models, variations in charged particle thresholds, light quark masses and the electron mass can completely alter the (testable) relation between ∆ lnα and ∆ lnμ, where μ ≡ mp/me. In extra-dimensional models where a compac...

Alpha phase reset contributes to the generation of ERPs.

An unresolved question in electroencephalogram (EEG) research is whether event-related potentials (ERPs) are generated by phase-reset or evoked response. We analyzed data of a visual feature detection task and will show 1) phase concentration in the alpha frequency range, 2) ongoing alpha activity prior to stimulus onset, 3) evoked alpha oscillation in the ERP, 4) lack of power increase during ...

Alpha-terthienyl: A plant-derived new generation insecticide

Alpha-terthienyl, a naturally occurring secondary plant metabolite is found in abundance in the roots of Tagetes species (family Asterasceae). It is activated by ultraviolet light and is toxic to a number of insect species. It generates oxygen radical species and has capacity to inhibit several enzymes like both in vivo and in vitro. Alpha-terthienyl possesses all the desirable properties of a ...

The Generation and Propagation of the Human Alpha Rhythm

Alpha-actinin binding kinetics modulate cellular dynamics and force generation.

The actin cytoskeleton is a key element of cell structure and movement whose properties are determined by a host of accessory proteins. Actin cross-linking proteins create a connected network from individual actin filaments, and though the mechanical effects of cross-linker binding affinity on actin networks have been investigated in reconstituted systems, their impact on cellular forces is unk...
