Abstract:
Abstract Several optical diagnostics in the ITER fusion reactor make use of big mirrors which are placed within the ITER vacuum vessel (VV), and therefore cannot have high accessibility. Plasma deposits developing on these mirrors may hinder the reflectivity of the mirror themselves, requiring a remote cleaning operation. The radio-frequency (RF) discharge mirror cleaning service operates a plasma discharge in the vicinity of the mirror, eroding the deposit layer and therefore cleaning the mirror remotely. In order to achieve this, RF power needs to be sent from outside the VV to the mirror, u

Abstract:
Deposition of synchrotron-radiation-induced carbon contamination on beamline optics causes their performance to deteriorate, especially near the carbon K edge. The photon flux losses due to carbon contamination have spurred researchers to search for a suitable decontamination technique to restore the optical surface and retain its performance. Several in situ and ex situ refurbishing strategies for beamline optics are still under development to solve this serious issue. In this work, the carbon contamination is removed from a large (340 mm × 60 mm) Au-coated toroidal mirror surface using a cap

Abstract We present an electro-mechano-optical radiofrequency (rf)-to-light signal transducer robust against laser heating and thus operational at room temperature.

The framework is based on perturbation theory on a continuous Fourier space, which leads to effective, i.e., time-independent, Hamiltonians.

Abstract:
In this study, HfO2 thin films were deposited onto the Si substrates by RF magnetron sputtering system. After deposition, the HfO2 thin films were then heated by a furnace thermal annealing process in air and at 400-700oC. The surface morphologies and crystalline characteristics of the HfO2 thin films were investigated by using SEM and XRD patterns. The grain sizes and crystalline phases increased with rising annealing temperature. In addition, the SiO2/HfO2 distributed bragg reflector (DBR) was used for improving the external quantum efficiency of the GaN-based LEDs. The output power of LEDs

Abstract:
This work presents a low-noise, low-power receiver RF front-end integrated circuit (IC) for 402–405[Formula: see text]MHz medical implant communications service (MICS) band applications using 0.18-[Formula: see text]m CMOS process. The proposed front-end employs an AC-coupled current mirroring amplifier in between the low-noise current-reuse transconductor amplifier and a single-balanced IQ mixer for improved gain and noise performance in comparison to previous works. The designed front-end IC achieves a simulated performance of 36.5[Formula: see text]dB conversion gain, 1.85[Formula: see text

Abstract:
Ultrasonic signals have been used in biomedical applications since at least the 1940s. Underwater acoustic signals have been used in the subsea industry for ranging since the early 1900s and for SONAR imaging and communication in the decades that followed. Since the development of subsea communication systems in the 1940s, increasingly sophisticated means have be developed for transmitting information acoustically through the highly variable ocean environment. State-of-the-art acoustic communication systems leverage ultrasonic transducers to achieve data transmission rates that mirror radio-fr

536 Background: The aim of EDIFICE surveys is to improve insight into the behavior of the French population with regard to cancer prevention and participation in screening programs. The colorectal cancer (CRC) screening program is in place and targets the 50-74-yr age group. CRC prevention also relies on increased awareness of known risk factors (behavioral [BRF] or non-behavioral [NBRF]). This analysis focuses on awareness of CRC risk factors among the lay population and physicians. Methods: The 4th nationwide observational survey was conducted by phone interviews using the quota method. A re
