Variation in the computation of slope from digital elevation data can result in significantly different slope values and can, in turn, lead to widely varying estimates of environmental phenomena such as soil erosion that are highly dependent on slope. Ten methods of computing slope from distributed elevation data, utilizing capabilities inherent in five different geographic information systems ...

A novel therapy is demonstrated utilizing magnetic nanoparticles for the dual purpose of delivering microRNA and inducing magnetic hyperthermia. In particular, the combination of lethal-7a microRNA (let-7a), which targets a number of the survival pathways that typically limit the effectiveness of hyperthermia, with magnetic hyperthermia greatly enhances apoptosis in brain cancer cells.

Existing OPAs are typically based on 2D rectangular arrays or 1D linear arrays. Both approaches present a limited field-of-view (FOV) due to the presence of grating lobes when element spacing is larger than λ/2. To address need for an increased steering range, we propose new design strategy OPA system utilizing circular phased array, with substantially FOV. We using demonstrated antenna design,...

in this study an ultra-broad band, low-power, and high-gain cmos distributed amplifier (cmos-da) utilizing a new gain-cell based on the inductively peaking cascaded structure is presented. it is created bycascading of inductively coupled common-source (cs) stage and regulated cascode configuration (rgc).the proposed three-stage da is simulated in 0.13 μm cmos process. it achieves flat and high ...
