According to the Einstein’s gravitational theory, zero-point energy in vacuum will collapse universe into a singularity if cut-off frequency of field is Plank frequency. But, according ZPF gravity theory proposed by author, dose not have mass as claimed theory. From which, it considered that correct.
conclusions based on 8.2 mm cut-off point could differentiate 83% periapical granulomas and 79% radicular cysts from radiography images. background the distinction between radicular cysts and apical granulomas is important in treatment decision. objectives the current study aimed to differentiate these two lesions based on radiography images. results average size of radiography in periapical gr...
This paper presents a low loss and high selective lowpass filter which is implemented using suspended stripline (SSL) technology. The proposed structure is comprised of a 13th order generalized Chebyshev lowpass filter which enjoys integrated waveguide-to-SSL transitions. This filter is designed and fabricated to be used as lowpass channel of a U-band diplexer employed in frontend of a U-band d...
Background: Finding a reliable diagnostic method for brucellosis is the most challengeable problem. In this study we determined the optimal diagnostic cut-off point for ELISA test.Methods: We gathered 56 confirmed cases of brucellosis. Furthermore blood samples from 126 controls including 73 healthy controls and 53 without brucellosis febrile patients were collected. In all of the cases and con...
All-pass digital filters are known as excellent prototype filters in many applications, such as control systems, signal processing and communications. Efficient filters can be designed because transfer function is very robust to small element changes. The drawback of digital filters based on all-pass filter sections is that they are not suitable for tuning and the design of filters with variabl...
Thank you for your useful comments. We will reply point by point. Comment : However, as pointed out by Dr Sargent in the interactive discussion, cut-off frequency is normally defined as the half-power point, and the amplitude spectrum at this frequencyfalls to 1= p 2 = 0:707, not 1=2 = 0:5. Please check it and re-calculate the results if necessary. Reply : Thanks for the remark. See also our re...
سابقه و هدف: فیبروز کبدی نتیجه محتوم بیماری های مزمن کبدی می باشدکه سر انجام به سمت سیروز پیشرفت می کنند. ارزیابی حضور و شدت فیبروز کبدی در بیماران با بیماری مزمن کبدی اهمیت زیادی در تعیین استراتژی درمان، پاسخ به درمان، پروگنوز و ریسک فاکتورهای بالقوه جهت بروز عوارض بیماری دارد. تاکنون بیوپسی کبد بهترین روش ارزیابی فیبروز کبد شناخته شده است ولی از آن جایی که روشی تهاجمی همراه با عوارض زیادی برا...
In this paper, we have presented a heterojunction gate all around nanowiretunneling field effect transistor (GAA NW TFET) and have explained its characteristicsin details. The proposed device has been structured using Germanium for source regionand Silicon for channel and drain regions. Kane's band-to-band tunneling model hasbeen used to account for the amount of band-to...
