In conventional analog filters operated in class-A mode, bias currents are large enough to accommodate the largest expected peak input signal. When only a small input signal (including in-band and out-of-band components) is present, these large bias currents unnecessarily waste power and create noise. A more optimal situation results if bias currents can be dynamically set by the system, depend...
Background & Aim: Inability to control drug use is considered a core aspect of drug dependency. Part of this inability is due to cognitive biases resulting from individuals’ constant usage of drugs. The aim of the present study was to compare the effectiveness of cognitive bias modification in real and placebo conditions on attentional bias and approach bias in opium abusers. Methods: This stud...
Emission spectroscopy analysis and imaging technique were used to study the microplasma phenomena. The microplasma discharge in Ar and N2/Ar was analyzed along the discharge gap area and also for specific periods of time during the discharge. Microplasma showed characteristics specific with an atmospheric glow discharge: positive column, Faraday dark space and negative glow. Spatial and tempora...
Evaluation of watershed projects is one of the most fundamental problems in countries for future implementation planning and management of natural resources. In regard to lack of required equipment for monitoring and evaluation of watershed projects and investigation of management measures in watersheds, application of hydrologic models is an efficient tool for simulation of watershed behavior ...
We demonstrate efficient, error-free 3.125Gb/s modulation of InP-based 1.3μm VCSELs with AsSb-based DBRs up to 60°C. These devices demonstrated high differential efficiencies (>60% at room-temperature), which resulted in a required bias current for modulation of only 5.9mA. The measured extinction ratios were greater than 8dB up to 60°C with a peak-to-peak drive voltage of only 800mV. The 3dB-d...
Sustaining environmental flows to preserve biodiversity of aquatic plant and animal species, as well as constancy of water for human communities, is essential in many river ecosystems. On the other hand, hydrological changes caused by the dam and its related environmental problems have provoked many concerns for hydrologists, ecologists and policymakers. Therefore, the main aim of this research...
