Aging and Rejuvenation with Fractional Derivatives [PDF]

open access: yes, 2004
We discuss a dynamic procedure that makes the fractional derivatives emerge in the time asymptotic limit of non-Poisson processes. We find that two-state fluctuations, with an inverse power-law distribution of waiting times, finite first moment and ...

Laser-Assisted Drug Delivery on the Face: A Systematic Review of Indications and Outcomes

open access: yesCosmetics, 2023
Laser-assisted drug delivery (LADD) has gained prominence as a promising technique with the potential to enhance topical drug skin penetration and absorption. However, the effectiveness of various laser-assisted facial procedures remains unclear.

Aging after shear rejuvenation in a soft glassy colloidal suspension: evidence for two different regimes

open access: yes, 2006
The aging dynamics after shear rejuvenation in a glassy, charged clay suspension have been investigated through dynamic light scattering (DLS). Two different aging regimes are observed: one is attained if the sample is rejuvenated before its gelation and

The Regulation of Plant Vegetative Phase Transition and Rejuvenation: miRNAs, a Key Regulator

open access: yesEpigenomes, 2021
In contrast to animals, adult organs in plants are not formed during embryogenesis but generated from meristematic cells as plants advance through development.

Fluorescent Light Energy (FLE) Generated through Red LED Light and a Natural Photoconverter Gel as a New, Non-Invasive Approach for Facial Age Control: A Pilot Study

open access: yesCosmetics, 2023
This study, for the first time, evaluated the safety and efficacy of a new natural-based topical gel containing a spirulina extract. This photoconverter gel generates fluorescent light energy (FLE) via a red LED light device, which is proven to be ...

Aging, rejuvenation and thixotropy in complex fluids. Time-dependence of the viscosity at rest and under constant shear rate or shear stress [PDF]

open access: yes, 2008
Complex fluids exhibit time-dependent changes in viscosity that have been ascribed to both thixotropy and aging. However, there is no consensus for which phenomenon is the origin of which changes.

Rejuvenation of spiral bulges [PDF]

open access: yesProceedings of the International Astronomical Union, 2006
AbstractWe seek to understand whether the stellar populations of galactic bulges show evidence of secular evolution triggered by the presence of the disc. To this end we re-analyse the sample of Proctor & Sansom (2002), deriving stellar population ages and element abundances from absorption line indices as functions of central velocity dispersion ...
