For the purpose of vision screening, we develop an eye fixation monitor that detects the fovea by its unique radial orientation of birefringent Henle fibers. Polarized near-infrared light is reflected from the foveal ...

The results of a study aimed at the determination of the concentration of Rhodamine-B dye at parts per billion (ppb) levels from remotely-sensed optical reflectancespectra of marine and fresh water are described. An ...

The room-temperature photoluminescence (PL) from silicon nanocrystals embedded in a SiO2 matrix fabricated by electron cyclotron resonance plasma-enhanced chemical vapor deposition and subsequent annealing in Ar and (Ar+5%H2) ...

We describe and characterize a multichannel modular room temperature photoluminescence spectroscopy system. This low cost instrument offers minimization of size and complexity as well as good flexibility and acceptable ...

Natural fibers extracted from natural sources have been exploited for a long time as fillers in reinforced polymer composites to provide strength and ductility. By selecting a proper ratio of the matrix and filler material, ...

Background. The efficacy of sacubitril/valsartan, a newly introduced combination drug for heart failure with reduced ejection fraction (HFrEF), was demonstrated in the PARADIGM-HF trial conducted in Western countries. ...

Many security applications are based on Pseudo Random Number Generators (PRNGs). Random binary numbers constitute a major reliance in many network security algorithms. For example, common cryptosystems require a long ...

The interfacial compatibility of the natural filler and synthetic polymer is the key performance characteristic of biocomposites. The fillers are chemically modified, or coupling agents and compatibilisers are used to ...

Perforation of building envelope is historically connected -in some circumstances- to the traditional architectural models (i.e. the ‘Mashrabiyya’) that consist of archetypical perforated elements to play technological, ...

The integrin alpha(v)beta3 has been shown to act as the receptor for internalization of foot-and-mouth disease virus (FMDV) (A12), with attachment being through a highly conserved RGD motif located on the G-H loop of viral ...
