In this paper we consider estimating the number of solutions to multiplicative equations in finite fields when variables run through certain sets with high additive structure. particular, energy generalized arithmetic progressions prime and boxes arbitrary fields. We obtain sharp bounds more general scenarios than previously known. Our arguments extend some ideas Konyagin Bourgain Chang into ne...

By calculating correlation spectra of the output fields, we show theoretically that two evanescently coupled χ(2) second harmonic generators inside a Fabry–Perot cavity provide a tunable source of quadrature squeezed light, Einstein–Podolsky–Rosen correlations and quantum entanglement. Unlike systems using coupled downconverters, second harmonic generation has no oscillation threshhold, so that...

Today medical and Healthcare industry generate loads of diverse data about patients, disease diagnosis, prognosis, management, hospitals’ resources, electronic patient health records, medical devices and etc. Using the most efficient processing and analyzing method for knowledge extraction is a key point to cost-saving in clinical decision making. Data mining, sometimes called data or knowledge...

The article highlights the contributions of a few prominent women scientists to the science of pharmacology. These women,some of whom were from other scientific fields, contributed significantly to our understanding of pharmacology. This was achieved in an era in which pharmacology was a more or less male dominated field. Even though it is easier for women to enter scientific fields nowadays, t...
