We propose a spectral prediction model for predicting the reflectance and transmittance of recto-verso halftone prints. A recto-verso halftone print is modeled as a diffusing substrate surrounded by two inked interfaces in contact with air (or with another medium). The interaction of light with the print comprises three components: (a) the attenuation of the incident light penetrating the print...

Complex thin oxide films with electro-optic (EO) properties are promising for use in advanced optical devices because of their large EO effect. We developed a method of aerosol deposition (AD) for fabricating EO films. The mechanism for AD is based on the solidification by impact of submicron particles onto a substrate. Since particles in AD films preserve their crystalline structure during the...

Polymer-stabilized blue phase liquid crystals (PS-BPLC) have become an increasingly important technology trend for information display and photonics applications. BPLCs exhibit several attractive features, such as reasonably wide temperature range, submillisecond gray-to-gray response time, no need for alignment layer, optically isotropic voltage-off state, and large cell gap tolerance. However...

conclusions demyelinating disease, anterior ischemic optic neuropathy, non-arteritic anterior ischemic optic neuropathy, autoimmune disease, and hereditary optic neuropathy could cause optic neuropathy. normal cbc parameters and the absence of clinical manifestations of vitamin b12 deficiency could not rule out its diagnosis. careful physical examinations and history-taking with a classical app...

Optic neuritis an inflammatory disorder of the optic nerve inflammation is usually in young’s with symptoms of eye pain and vision loss that occurs is a common symptom of MS. Optic neuritis is one of the first symptoms of MS that observable into disorders in white matter of cerebral cortex. The risk of MS in patients with optic neuritis during 2 years 20% in 15 years, 45-80% is calculated...

Homogeneously distributed zinc nanoparticles (NPs) on the glass substrate were investigated for the transmittance, mechanical durability, and antibacterial effect. The buffered Ti NPs between Zn NPs and glass substrate were studied for an enhancement of the transmittance and mechanical endurance. The Ti NPs buffered Zn NPs showed a high transmittance of approximately 91.5% (at a wavelength of 5...

Changes in intrinsic optical signals could be related to cell swelling; however, the evidence is not compelling. We measured light transmittance, ECS volume fraction (alpha), and extracellular K+ in rat spinal cord slices during electrical stimulation and the application of elevated potassium, NMDA, or anisoosmotic solutions. Dorsal root stimulation (10 Hz/1 min) induced an elevation in extrace...

An experimental setup and procedure for accurate transmittance measurements of candidate filters for the Auger Fluorescence Detector is presented. For this check, we used the Hitachi U-2000 double-beam spectrophotometer (Sph) of the Chemical Department of the University of Athens (UoA). After the calibration of the Sph, we are able to observe transmittance deviations over the area of the filter...
