Smoothing out Negative Tension Brane [PDF]

, 2008
We propose an extension of the five dimensional gravitational action with an external source in order to allow arbitrary smoothing of the negative tension brane in the Randall-Sundrum model.

Weyl Invariance and Black Hole Evaporation [PDF]

, 1995
We consider the semiclassical dynamics of CGHS black holes with a Weyl-invariant effective action for conformal matter. The trace anomaly of Polyakov effective action is converted into the Virasoro anomaly thus leading to the same flux of Hawking ...

The scar mechanism revisited [PDF]

, 2007
Unstable periodic orbits are known to originate scars on some eigenfunctions of classically chaotic systems through recurrences causing that some part of an initial distribution of quantum probability in its vicinity returns periodically close to the ...

Mechanism of action of VP1-001 in cryAB(R120G)-associated and age-related cataracts [PDF]

, 2019
PurposeWe previously identified an oxysterol, VP1-001 (also known as compound 29), that partially restores the transparency of lenses with cataracts. To understand the mechanism of VP1-001, we tested the ability of its enantiomer, ent-VP1-001, to bind ...

Appearence of Mother Universe and Singular Vertices in Random Geometries

, 1996
We discuss a general mechanism that drives the phase transition in the canonical ensemble in models of random geometries. As an example we consider a solvable model of branched polymers where the transition leading from tree- to bush-like polymers relies

Depression, an unmet health need in Africa: Understanding the promise of ketamine

Heliyon
In Africa, there is currently a paucity of data on the epidemiology of depression, its treatment and management. The prevalence of depression is severely underestimated, with unique circumstances and societal risk factors associated with depression and ...

Role of micronutrients and natural antioxidants in fighting against HIV; a quick mini-review [PDF]

Research Journal of Pharmacognosy, 2014
Oxidative stress has been implicated in the progression of HIV to AIDS, since HIV usually replicates in a highly oxidized condition and CD4+ T lymphocytes can be activated via a cascade of internal oxidative pathways, which enhances the formation of ...
