the desire to achieve cosmetic rejuvenation and reduce effects of aging and photodamage urged scientists to develop effectual techniques which have minimal side effects and impressive long-term efficacy. traditional ablative resurfacing laser therapy has been used for several years;however, it has harmful side effects on the patient’s skin such as dyspigmentation, persistent erythema, infection...

Chocolate is known to undergo solid–liquid transition upon an increase in temperature as well under application of deformation field. Upon sudden reduction from a molten state (or thermal rejuvenation), the rheological properties chocolate evolve function time isothermal conditions, behavior reminiscent physical aging polymeric glasses. Then again, subsequent cessation shear flow mechanical sho...

BACKGROUND The periorbital region serves as a barometer of chronologic and environmental age and, as such, patients often seek its cosmetic rejuvenation. OBJECTIVE The purpose of this article was to review the dermatologic treatments available for periorbital skin rejuvenation. METHODS Topical retinoic and glycolic acid preparations, chemical peels, botulinum and collagen injections, dermab...

A number of recent studies have reported the phenomenon of “software aging”, characterized by progressive performance degradation and/or an increased occurrence rate of hang/crash failures of a software system due to the exhaustion of operating system resources or the accumulation of errors. To counteract this phenomenon, a proactive technique called “software rejuvenation” has been proposed. I...

Rebooting is one of the commonly used approaches to recover from undesired crash or performance degradation in software systems. Recently, however, planned and periodic restart or rejuvenation has been proposed as a reliability management tool for avoiding unwanted failure of long-running systems. This paper presents an interesting observation that periodic rejuvenation alters the lifetime dist...

Generalized Renewal Processes are useful for approaching the rejuvenation of dynamical systems resulting from planned or unplanned interventions. We present new perspectives for the Generalized Renewal Processes in general and for the Weibull-based Generalized Renewal Processes in particular. Disregarding from literature, we present a mixed Generalized Renewal Processes approach involving Kijim...

We discuss a dynamic procedure that makes 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 divergent second moment, namely, with the power index mu in the interval 2<mu<3 , yield a generalized master equation equivalent to the sum of an ordin...
