In countries where avian influenza has become endemic, early vaccination of layer pullets or broilers with classical inactivated vaccines at the hatchery is no longer an option because of interference with passive immunity indirectly induced by the necessary vaccination of the breeders. On the other hand, injection of thousands of chicks from 7 to 10 days old on farms has been determined to be ...
The prediction of the lineage dynamics of influenza B viruses for the next season is one of the largest obstacles for constructing an appropriate influenza trivalent vaccine. Seasonal fluctuation of transmissibility and epidemiological interference between the two major influenza B lineages make the lineage dynamics complicated. Here we construct a parsimonious model describing the lineage dyna...
In the study of measures to improve channel efficiency, we developed and presented a performance analysis digital communication system for image transmission in multipath with fading, MATLAB/Simulink environment, one main advan tages being that it provides high interference immunity presence noise signal delays. The scheme has been investigated bit error rate (BER) on additive white Gaussian (A...
An optimal receiving device for information signals of tonal rail circuits has been synthesized. The are observed against the background an additive five-component interference. first component interference is broadband Gaussian noise. other four components structurally determined: single impulse interference, from adjacent circuit, and multiharmonic alternating traction current combined with p...
In the past decade, small RNA pathways have been identified as a major mechanism of gene regulation. From an immunity standpoint, these pathways play a central role either by regulating immune reactions or by acting as immune effectors. In insects, several studies have unravelled the role of RNA interference (RNAi) as an antiviral response and have uncovered a complex relationship between insec...
Together with the use of number repurposed/ repositioned antiviral drugs and immunomodulatory agents against severe acute respiratory coronavirus 2 (SARS-CoV-2) infection, currently several vaccines are under human trials to mitigate COVID-19 worldwide. Although appear be effective in maximum cases or trials; however, associated side effects, required induction long-lasting immunity, finally, s...
Compared with the traditional Rogowski coil, printed circuit board (PCB) coil has advantages of high measurement accuracy, simple manufacturing process and low cost. It become an important device in current measurement. However, existing PCB coils are mostly closed, open-ended structure susceptible to external magnetic field interference. This paper proposes based on a new winding method, so th...
In this paper, the susceptibility to Electromagnetic Interference (EMI) of an analog signal acquisition front-end (AFE) due EMI distortion in opamp-based pre-conditioning amplifiers is addressed. More specifically, possibility correct EMI-induced errors digital domain by post-processing acquired waveforms discussed and experimentally demonstrated for first time with reference AFE based on EMI-s...
Abstract Since it does not depend on the starting point selection, data field clustering can perform unsupervised according to distribution characteristics. However, due its drawback of high computational complexity caused by iterative updates, is suitable for scenarios with real-time requirements such as radar signal sorting. In this paper, an improved method selection proposed address problem...
exposure to high dosages of sulfur mustard (sm) can cause bone marrow depression, immune system suppression, impairment of the immune functions, and eventually results in diseases due to secondary immune disorders. in this article, we have studied the effects of this poison on iranian veterans by analysis of related published studies. in a systematic search, the effects of sm gas on iranian vic...
