An appealing requirement from the well-known diffraction tomography (DT) exists for success reconstruction from few-view and limited-angle data. Inspired by the well-known compressive sensing (CS), the accurate super-resolution reconstruction from highly sparse data for the weakly scatters has been investigated in this paper. To realize the “compressive” data measurement, in particular, to obta...

This paper demonstrates the environmental impacts of wildfires occurring at beginning April 2020 in and around highly contaminated Chernobyl Exclusion Zone (CEZ). Due to critical fire location, concerns arose about secondary radioactive contamination potentially spreading over Europe. The impact was assessed through evaluation plume dispersion re-suspension radionuclide Cs-137, whereas, assess ...

Double-reconfigurable intelligent surface (RIS) is a promising technique, achieving substantial gain improvement compared to single-RIS techniques. However, in double-RIS-aided systems, accurate channel estimation more challenging than single-RIS-aided systems. This work solves the problem of double-RIS-based based on active RIS architectures with only one radio frequency (RF) chain. Since slow...

Hybrid analog-digital (HAD) architecture is widely adopted in practical millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) systems to reduce hardware cost and energy consumption. However, channel estimation the context of HAD challenging due only limited radio frequency (RF) chains at transceivers. Although various compressive sensing (CS) algorithms have been developed solv...

objective: cyclosporine (cs), a cyclic undecapeptide with potent immunosuppressive activity, causes several adverse effects including reproductive toxicity. this study aims to examine the ability of crataegus monogyna aqueous fruit extract as an antioxidant to protect against cs-induced reproductive toxicity. materials and methods: in this experimental study, 32 adult male wistar rats were divi...

background: the effects of cyclosporine (cs), a fungal cyclic polypeptide with potent immunosuppressive activity, on fertility have assumed greater significance with the increasing numbers of transplantations being performed all over the world. current study was undertaken to investigate the potential of satureja khuzestanica essential oil (seo) as an antioxidant to mitigate cs-induced reprotox...

introduction: the aim of this study was to evaluate the effect of adding propylene glycol (pg) to mineral trioxide aggregate (mta) liquid with volume ratio of 20% on the compressive strength (cs) of mta in two time periods (4 and 21 days) after mixing. methods and materials: four groups of steel cylinders ( n =15) with an internal diameter of 3 and a height of 6 mm were prepared and mta (groups...

Text Classification is an important research field in information retrieval and text mining. The main task in text classification is to assign text documents in predefined categories based on documents’ contents and labeled-training samples. Since word detection is a difficult and time consuming task in Persian language, Bayesian text classifier is an appropriate approach to deal with different...
