An X Band Radio Channel Model for Propagation Through the Solar Corona
(2018)Spacecraft communication systems operating at X band are strongly affected when the propagation path passes close to the Sun (which can be characterized by the Sun-Earth-Probe, SEP, angle). In this paper, a channel model ... -
X-TMCMC: Adaptive kriging for Bayesian inverse modeling
(2015)The Bayesian inference of models associated with large-scale simulations is prohibitively expensive even for massively parallel architectures. We demonstrate that we can drastically reduce this cost by combining adaptive ... -
Xanthine oxidase inhibitors may prevent or slow chronic kidney disease even in the absence of hyperuricemia
(2018)[No abstract available] -
Xanthogranulomatous salpingitis: Report of three cases and comparison with a case of pseudoxanthomatous salpingitis
(2008)Xanthogranulomatous inflammation, an uncommon form of chronic inflammation, has been described in several organs including those of the female genital tract. A rare condition described as pseudoxanthomatous salpingitis or ... -
XbaI GLUT1 gene polymorphism and the risk of type 2 diabetes with nephropathy
(2009)Altered expression of the facilitated glucose transporter GLUT1 affects pathways implicated in the pathogenesis of diabetic nephropathy. There is indication that variation of GLUT1 gene (SLC2A1) contributes to development ... -
The xbr+-tree: An efficient access method for points
(2015)Spatial indexes, such as those based on Quadtree, are important in spatial databases for efficient execution of queries involving spatial constraints. In this paper, we present improvements of the xBR-tree (a member of the ... -
Xcas as a programming environment for stability conditions for a class of differential equation models in economics
(2011)In this paper we examine the property of asymptotic stability in several dynamic economic systems, modeled in ordinary differential equation formulations of time parameter t. Asymptotic stability ensures intertemporal ... -
XOR-Based Encoding With Instantaneous Decoding for the Broadcast Erasure Channel With Feedback: The Three-User Case
(2014)We study the case of a three-user broadcast erasure channel with multiple unicast traffic sessions, where feedback from the users is fed back to the transmitter in the form of positive acknowledgment (ACK)/negative ... -
Y DNA and mitochondrial lineages in European and Asian populations of the brown hare (Lepus europaeus)
(2010)Both the Cytb gene of mtDNA and Y chromosome markers were studied in a relatively large sample of brown hares (L. europaeus) from Europe and Anatolia (Turkey and Israel), together with other seven Lepus species, in order ... -
Yearly numerical evaluation of greenhouse cover materials
(2018)The greenhouse internal microclimate, and consequently the plants growth, is formed from the combination of available solar radiation and ventilation. Transpiration and photosynthesis are affected by the PAR levels, as ... -
Years of training and hamstring-quadriceps ratio of soccer players
(2007)To investigate the effect of the years of training on the hamstring-quadriceps isokinetic strength and establish normative data for the cardiorespiratory fitness of first and second division Greek male professional soccer ... -
Yellow nail syndrome or diffuse lymphatic network disease
(2002)We report a man aged 68 years old with pneumothorax and chronic bilateral pleural effusion in association with a history of yellow nails. The diagnosis of yellow nail syndrome based on yellow nails, lymphedema, chronic ... -
Yield and quality of lettuce and rocket grown in floating culture system
(2016)In recent years, there has been a growing trend towards cultivating leafy vegetables in hydroponic systems. Floating system is an alternative hydroponic system suitable for the production of baby vegetable products, ready-to ... -
Yield and seed quality parameters of common bean cultivars grown under water and heat stress field conditions
(2019)Drought and heat stress strongly influence common bean development. The aim of this work was to study the effect of water stress on yield and quality traits of four common bean cultivars under xerothermic Mediterranean ... -
Yield and silymarin content in milk thistle (Silybum marianum (L.) Gaertn.) fruits affected by the nitrogen fertilizers
(2021)Milk thistle (Silybum marianum (L.) Gaertn.) is a common weed that has been introduced as a medicinal plant for silymarin production. This renders it important to optimize cultivation techniques, including fertilization. ... -
Yield performance at three nitrogen rates of a set of honeycomb vs traditional pedigree selected bread wheat varieties
(2003)The honeycomb nil interplant competition selection procedure has been proposed as effective breeding methodology in developing high yielding and broadly adapted wheat varieties. The objective of this research were to (i) ...
