High dynamic range (HDR) displays with dual-panels are one type of that can provide HDR content. These composed a white backlight panel and colour LCD panel. Local dimming algorithms used to control the in order reproduce content high contrast at fidelity. However, existing local usually process low (LDR) images, which not suitable for processing images. In addition, these methods use hand-craf...

This paper introduces a novel dimming method for Light Fidelity (LiFi) based on time-domain sample index modulation (TIM), called indexed (iDim). The aim is to provide wide brightness range, while maintaining high signal-to-noise ratio (SNR) performance and transmission rate. Direct current optical orthogonal frequency division multiplexing (DCO-OFDM) used line codes are presented. system exper...

Free electrons deplete photons from type Ia supernovae through the (inverse) Compton scattering. This Compton dimming increases with redshift and reaches 0.004 mag at z = 1 and 0.01 mag at z = 2. Although far from sufficient to invalidate the existence of dark energy, it can bias constraint on dark energy at a level non-negligible for future supernova surveys. This effect is correctable and sho...

introduction: in open reduction and internal fixation for the treatment of mandibular fracture, the fixation technique used is very important in reducing post-operative complications and promoting the healing process. this study assessed the results of fixation of the mandible using two mini-plates perpendicular to each other in the lower border of the mandible for fracture treatment.    materi...

objectives: the aim of this study was to assess nutritional status and identify the most significant mna-items (mini nutritional assessment) to accelerate the determination of nutritional risk of heart-failure in elderly patients. methods and materials: the present research was a cross-sectional descriptive analytical survey on hospitalized heart- failure elderly patients (n=225). the sampling ...

Background: Recently, some new viruses have been identified for their association with hepatitis which Torque Teno Mini Virus being among them. The aim of this study was to determine the frequency of Torque Teno Mini Virus in healthy individuals and hepatitis B and C patients in Isfahan, Iran. Materials and Methods: One hundred serum samples of healthy individuals from Isfahan Blood Transfusi...

ABSTRACT We assess whether gravity darkening, induced by a tidal interaction during stellar fly-by, might be sufficient to explain the Great Dimming of Betelgeuse. Adopting several simple approximations, we calculate deformation and associated darkening in close encounter, as well reduction radiation flux seen distant observer. show that, principle, duration degree resulting dimming can used es...
