The use of high-power diode laser with a wavelength of 755 nm is an effective and safe method for the correction and partial and/or total elimination of pigmented lesions, specifically solar lentigines. This wavelength has yet not been used in diode lasers to treat solar lentigines. Side effects are the usual ones, including darkening and scab formation. Our patient was a 40-year-old woman of C...

High level power estimation is essential for designing complex low-power ICs. However, the lack of flexibility of all previously presented high level power estimation approaches limits their use to small (datapath) parts of ICs. In this paper a more general and flexible high level power estimation approach is presented, based on VHDL simulation. The obtained results are very encouraging.

In this article, we review progress in the development of high peak-power ultrafast lasers, and discuss in detail the design issues which determine the performance of these systems. Presently, lasers capable of generating terawatt peak powers with unprecedented short pulse duration can now be built on a single optical table in a small-scale laboratory, while large-scale lasers can generate peak...

Energy and power density are the key figures of merit for most electrochemical energy storage systems. Considerable efforts worldwide have been made to improve the energy density of rechargeable (secondary) batteries, as this is critical for most applications. As the penetration of batteries into ever more demanding applications has increased, power density, the allowed rate of energy transfer ...

The jets of powerful blazars propagate within regions relatively dense of radiation produced externally to the jet. This radiation is a key ingredient to understand the origin of the high energy emission of blazars, from the X–ray to the γ–ray energy band. The main components contributing to the external radiation field are the accretion disk emission, including its X–ray corona, the broad line...
