Rydberg atom can respond to weak microwave electric field signal in real-time by using its electromagnetically induced transparency effect realize down conversion of space signal, which be used as a superheterodyne receiver. The receiver is new receiving system composed atoms, photodetectors, and electronic information processing modules. Presently, the physical response mechanism atomic techno...

conclusions the in-house 1 step taqman real time rt-pcr assay showed acceptable performance characteristics. our study presents the robustness and cost-effectiveness of the method for detection and quantification of hcv rna. methods the primers and probe were selected from a highly conserved region of the hcv genome, which allowed the detection of 4 common hcv genotypes in iran. using 4 quantif...

background and objectives: rheological characteristics of dough are important for achieving useful information about raw-material quality, dough behavior during mechanical handling, and textural characteristics of products. our purpose in the present research is to apply soft computation tools for predicting the rheological properties of dough out of simple measurable factors. materials and met...

An analysis of tnmel-diode low-level detection is presented for the purpose of explaining some of the unusual detection characteristics that occur under certain hias conditions. For example, in the vicinity of its inflection hias point, a tmmel diode exhibits a discriminator-like rectification behavior with two sensitivity peaks. When biased at one of these peaks, the diode is capable of unusua...

OBJECTIVES We investigated the validity of the dipstick method (Mossman Associates Inc. USA) and the expired CO method to distinguish between smokers and nonsmokers. We also elucidated the related factors of the two methods. METHODS This study included 244 smokers and 50 ex-smokers, recruited from smoking cessation clinics at 4 local public health centers, who had quit for over 4 weeks. We ca...

In this study, using methacrylic and ascorbic acid in gelatin initiated by copper (MAGIC-f) polymer gel after megavoltage energy exposure, the sensitivity of the ultrasound velocity and attenuation coefficient dose-dependent parameters was evaluated. The MAGIC-f polymer gel was irradiated under 1.25 MeV cobalt-60, ranging from 0 to 60 Gy in 2-Gy steps, and received dose uniformity and accuracy ...

Efficient sensitivity analysis, particularly for the global sensitivity analysis (GSA) to identify the most important or sensitive parameters, is crucial for understanding complex hydrological models, e.g., distributed hydrological models. In this paper, we propose an efficient integrated approach that integrates a qualitative screening method (the Morris method) with a quantitative analysis me...
