increasing development of nano-technology in optics and photonics by using modern methods of light control in waveguide devices and requiring miniaturization and electromagnetic devices such as antennas, transmission and storage as well as improvement in the electromagnetic tool, have led researchers to use the phenomenon of electromagnetically induced transparency (eit) and similar phenomena i...

AIMS We sought to compare the results obtained from six major platelet function tests in the assessment of the prevalence of aspirin resistance in patients with stable coronary artery disease. METHODS AND RESULTS 201 patients with stable coronary artery disease receiving daily aspirin therapy (> or =80 mg) were recruited. Platelet aggregation was measured by: (i) light transmission aggregomet...

A series of novel 2-aminopyrimidine and 2-Substituted-4,6-diaminopyrimidine derivatives have been synthesized and their anti platelet aggregation activities were assessed against ADP and arachidonic acid- induced platelet aggregation in human plasma using light transmission aggregometry. None of the compounds showed satisfactory activity against the aggregation induced by ADP. However, satisfac...

We present an algorithm for efficient rendering of animated hair under a dynamic, low-frequency lighting environment. We use spherical harmonics (SH) to represent the environmental light. The transmittances between a point on a hair strand and the light sources are also represented by SH functions. Then, a convolution of SH functions and the scattering function of a hair strand is precomputed. ...

BACKGROUND Anticoagulation protocols used during mechanical circulatory support call for titration of antiplatelet agents. We compared the precision and reliability of 5 platelet function tests in healthy volunteers and donors on daily antiplatelet therapy to distinguish their efficacy for titrating antiplatelet therapy. METHODS We assessed arachidonic acid-induced platelet function by light ...

A novel scatterometry method, based on broadband measurements of reflectance and transmittance spectra is presented. For the first time Rigorous Coupled Wave Analysis (RCWA) algorithm is applied to the analysis of the transmittance spectra for the determination of trench depths, critical dimensions, profiles, film thicknesses, and optical properties (n and k spectra from 190 – 1000 nm) of phase...
