In this work, a defect based photonic crystal (PC) structure presented for design of tunable infrared photodetector. Absorption response was investigated under the effects of various structural parameters. Using straight transfer matrix method, PC band edge effect was studied on absorption and a significant absorption enhancement up to %96 was achieved for defect-based structure.

All existing similarity-based gene recognition algorithms can use only one protein as a template. The proposed enhancement of the ProFrame algorithm allows one to use structural information about several related proteins in multiple alignment. The new algorithm, named ProMult, was tested on a sample of human genes and demonstrated improved reliability of predictions.

Cross-reactive dengue virus (DENV) antibodies directed against the envelope (E) and precursor membrane (prM) proteins are believed to contribute to the development of severe dengue disease by facilitating antibody-dependent enhancement of infection. We and others recently demonstrated that anti-prM antibodies render essentially non-infectious immature DENV infectious in Fcγ-receptor-expressing ...

Single-crystal micro- and nanomaterials often exhibit higher yield strength than their bulk counterparts. This enhancement is widely recognized in structural materials but is rarely exploited to probe fundamental physics of electronic materials. Vanadium dioxide exhibits coupled electronic and structural phase transitions that involve different structures existing at different strain states. Fu...
