Radiation pressure has recently been used to effectively couple the quantum motion of mechanical elements to the fields of optical or microwave light. Integration of all three degrees of freedom-mechanical, optical and microwave-would enable a quantum interconnect between microwave and optical quantum systems. We present a platform based on silicon nitride nanomembranes for integrating supercon...
This paper will summarized the different size of opening width and length of the slot flare Vivaldi Antenna. The different size of opening width and length will bring effects on the VSWR and S11. The Vivaldi Antenna is designed to cover from 2 to 18 GHz by using the CST Microwave Studio Software. Then these antennas are constructed using RT/Duroid 5870 which have dielectric constant r 2.33. T...
We take beneet from a causal Markov model deened on a quadtree to derive a multiresolution EM algorithm for unsupervised image classiication. This algorithm is an eecient alternative to expensive or approximate EM algorithms associated with Markov Random Fields. We show on synthetic and real images that our algorithm also provides good or even better results than those obtained by spatial MRF m...
Magnetobiology—the science studying the effect of weak, below 0.1 mT, magnetic fields on biological systems—is a new synthetic discipline encompassing the principles and techniques of many sciences, from physics to medicine, and centered around biophysics. Both the theoretical foundation and general physical concepts of magnetobiology remain to be established. Suffice it to say that magnetobiol...
A new class of cross-coupled planar microwave filters using microstrip hairpin resonators is introduced. The realization of both the canonical and the cascaded quadruplet (CQ) filters is feasible. Coupling characteristics of four basic coupling structures encountered in this class of filters are investigated in the light of full-wave electromagnetic (EM) simulations. A four-pole cross-coupled f...
Electromagnetic fields are created by radiofrequency waves. However, the RF emitted a mobile phone's antenna is insufficient to cause significant heating of tissues in ear or head. The focus this research look further into SAR measurement how much radiation absorbed human body. A CST Microwave studio, high-performance 3D EM analysis software, used for project design, analyse, and measure electr...
The airways of patients with bronchiectasis and cystic fibrosis are often chronically colonised by Pseudomonas aeruginosa (PA), which is virtually impossible to eradicate. Low-dose erythromycin (EM), for unknown mechanisms, is efficacious in bronchiectasis and diffuse panbronchiolitis. In this study, an in vitro model to investigate PA adherence to human type IV basement collagen was developed ...

Biological noise has already been shown to play a constructive role in neuronal processing and reliability, according to a phenomenon known as stochastic resonance (SR). This phenomenon has been previously observed by the authors in the detection of electromagnetic (EM) fields in the case of an additive white Gaussian input, roughly approximating the ensemble of noise sources. Recently, attenti...
Background & Aim: A simple and rapid microwave- assisted extraction (MAE) procedure was developed and optimized for the isolation of borneol and bornyl acetate from Ferulago macrocarpa. Ferulago macrocarpa (Apiaceae) is an endemic plant in Iran. Experimental: Dried powdered aerial parts of plants were soaked in water and irradiated with microwave in a Clevenger extraction app...
