Advances in device fabrication, modelling and design techniques have made wide band, low noise cryogenic amplifiers available at frequencies up to 106 GHz. Microwave radiometry applications as used in radio astronomy capitalize on the low noise and large bandwidths of these amplifiers. Radiometers must be carefully designed so as to preclude sensitivity degradations caused by small, low frequen...

Preoperative skin preparation with antimicrobial agents decreases the risk of surgical site infection, but concerns have been raised about the visibility of a common surgical preparatory agent (ChloraPrep; Becton, Dickinson & Co, Franklin Lakes, New Jersey), depending on skin pigmentation. Poor visibility may lead to failure to identify inadequately prepared skin, increasing the risk of surgica...

Abstract The effects of pre-fermentative freezing red grapes from Schiava variety and co-inoculation with lactic bacteria were evaluated on the profile anthocyans musts finished wine. Peonidin-3-glucoside is main anthocyanin in grape musts, but it was overcome by malvidin-3-glucoside at bottling. Grape increased extraction all anthocyanins musts. However, amount except peonidin-3-glucoside lowe...

The collective movement of animal groups often occurs in confined spaces. As animal groups are challenged to move at high density, their mobility dynamics may resemble the flow of densely packed non-living soft materials such as colloids, grains, or polymers. However, unlike inert soft-materials, self-propelled collective living systems often display social interactions whose influence on colle...

The problem of gamut mapping is of interest in achieving an optimum color reproduction whenever a translation from one device (source) to another device (destination) is requested and the source gamut differs from destination gamut. For printing applications, if the ICC profile specifications are used, gamut mapping is applied to build the color tables that characterize the printing device. Wit...

Little is known about the role of weak interlayer coupling in second harmonic generation (SHG) effects two-dimensional van der Waals (vdW) systems. In this article, taking homo-bilayer $MoS_2/MoS_2$ and hetero-bilayer $MoS_2/MoSe_2$ as typical examples, we have systemically investigated their SHG susceptibilities a function hopping strength using first-principles calculations. For at zero frequ...
