A Compact Impedance Model of Plasmonic Nanoshell for Metamaterial Applications
IEEE transactions on nanotechnology, 2019 Recent research in plasmonics demonstrated merging different materials and shapes to form complex geometries with improved optical response. One of the most extensively used nanostructure is the coated nanosphere (nanoshell), which finds its application ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

Fatigue-Induced Cole Electrical Impedance Model Changes of Biceps Tissue Bioimpedance
Fractal and Fractional, 2018 Bioimpedance, or the electrical impedance of biological tissues, describes the passive electrical properties of these materials. To simplify bioimpedance datasets, fractional-order equivalent circuit presentations are often used, with the Cole-impedance ...

Impedance method with interpolation applied to skin impedance modeling [PDF]
Revista Brasileira de Engenharia Biomédica, 2011 A new approach based on the use of interpolation for the electric potential is proposed to increase the accuracy of field calculation using the impedance method. In each voxel of a three-dimensional grid, the electric field is calculated from the potential interpolation function and is used as a solution of the continuity equation.

Mapping the evolution of mitochondrial complex I through structural variation
FEBS Letters, EarlyView.Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
