The accurate simulation of microwave observations clouds and precipitation are computationally challenging. A common simplification is the assumption totally random orientation (TRO); however, studies have revealed that TRO occurs relatively infrequently in reality. more appropriate azimuthally (ARO), but so far it has been a expensive task. Recently fast approximate approach was introduced inc...
مقدمه: شیرین‌بیان با نام علمی Glycyrrhiza glabra از خانواده لگومینوز می‌باشد که از مشهورترین گیاهان دارویی در جهان است و به شکل گسترده‌ای در پزشکی، داروسازی، صنایع قنادی و بهداشتی مصرف می‌شود. قسمت‌های مورد استفاده آن ساقه‌های زیرزمینی و ریشه‌های گیاه است که دارای ترکیبات مختلفی است، از جمله مهم‌ترین این مواد، ترکیبی به نام گلیسریزین است. هدف: پژوهش حاضر با هدف انتقال ژن ریشه‌زایی از طریق آگرو...
In this article, we propose a geometric shaping (GS) strategy to design 8, 16, 32, and 64-ary modulation formats for the optical fibre channel impaired by both additive white Gaussian (AWGN) phase noise. The constellations were optimised maximise generalised mutual information (GMI) using mismatched model. presented demonstrate an enhanced signal-to-noise ratio (SNR) tolerance in high noise reg...
BACKGROUND & OBJECTIVES The study was aimed at determining the prevalence and intensity of Wuchereria bancrofti microfilaraemia in a high altitude region of south-eastern Nigeria, and ascertaining the prevalence of clinical signs and symptoms associated with the filarial infections. METHODS Thick smear of 50 μl finger-prick blood collected at night between 2200 and 0200 hrs from consenting pe...
BACKGROUND AND PURPOSE To evaluate the variation in investigator-delineated volumes and assess plans from the radiotherapy trial quality assurance (RTTQA) program of SCALOP, a phase II trial in locally advanced pancreatic cancer. MATERIALS AND METHODS Participating investigators (n=25) outlined a pre-trial benchmark case as per RT protocol, and the accuracy of investigators' GTV (iGTV) and PT...
Interactions between multiple myeloma (MM) cells and the BM microenvironment play a critical role in the pathogenesis of MM and in the development of drug resistance by MM cells. Selectins are involved in extravasation and homing of leukocytes to target organs. In the present study, we focused on adhesion dynamics that involve P-selectin glycoprotein ligand-1 (PSGL-1) on MM cells and its intera...
In this paper, we propose novel non-linear precoders for the downlink of a multi-user MIMO system with the existence of multiple eavesdroppers. The proposed non-linear precoders are designed to improve the physical-layer secrecy rate. Specifically, we combine the non-linear successive optimization TomlinsonHarashima precoding (SO-THP) with generalized matrix inversion (GMI) technique to maximiz...
