The use of visible or near-infrared spectral light alone for the purpose of skin rejuvenation has been previously reported in the literature. These devices use large arrays of diodes to deliver light to the skin. In this study, a novel method of light-emitting diode (LED) photo rejuvenation incorporating a combination of these wavelengths delivered from a small handheld unit is proposed. Twenty...

In this paper, we propose a high availability design of a Cable Modem Termination System (CMTS) clusters system based on the software rejuvenation technique. This proactive system maintenance technique is aimed to reduce system outages and the associated downtime cost due to the ‘software aging’ phenomenon. Different rejuvenation policies are studied from the perspectives of design, implementat...

Rejuvenation of metallic glasses, bringing them to higher-energy states, is of interest in improving their plasticity. The mechanisms of rejuvenation are poorly understood, and its limits remain unexplored. We use constrained loading in compression to impose substantial plastic flow on a zirconium-based bulk metallic glass. The maximum measured effects are that the hardness of the glass decreas...

Certain gateways (e.g., some cable or DSL modems) are known to have low reliability and low availability. Most failures of these devices can however be “fixed” by rejuvenating the device after a failure has been detected. Such a detection based rejuvenation strategy permits increasing the availability of these gateways. In the considered scenario, rejuvenation is non-trivial since a failure of ...

This is the second of the three articles discussing volumetric rejuvenation of the face. The previous article, Volume Rejuvenation of the Facial Upper Third, focused on the upper one-third of the face while this article focuses on the middle one-third, primarily the lower eyelid, cheek, and perioral area. Again, the authors (RG, TK, SPS, RF, SL, and EFW) from the upper face article have provide...

This is the third and final article discussing volumetric rejuvenation of the face. The previous two articles, Rejuvenation of the Upper Third and Management of the Middle Third, focused on the upper two-thirds of the face while this article focuses on the lower face, including the marionette area, jawline, and neck. Again, the authors of the previous two articles have provided a summary of rej...
