A uniform linear array (ULA) or a multi-element planar composed of arrays is the main applied research for direction-of-arrival (DOA) estimation in signal processing. In recent years, circular (UCA) getting more attention because its consistent azimuthal beam resolution, but DOA algorithm UCA complex and difficult to implement. To solve this problem, positioning method based on virtual interpol...
This is the first of two chapters of a work in which we consider the unrestricted, minimal, and bounded representation problems for unit interval (UIG) and unit circular-arc (UCA) graphs. In the unrestricted version, a proper circular-arc (PCA) modelM is given and the goal is to obtain an equivalent UCA model U . In the bounded version,M is given together with some lower and upper bounds that t...
BACKGROUND Provocative testing with sodium channel blockers is advocated for the evaluation of unexplained cardiac arrest (UCA) with the primary purpose of unmasking the typical ECG features of Brugada syndrome. The Cardiac Arrest Survivors with Preserved Ejection Fraction Registry (CASPER) systematically assesses subjects with UCA or a family history of sudden death (FHSD). OBJECTIVE The pur...
Genetic hypercalciuric stone-forming (GHS) rats, bred to maximize urine (U) calcium (Ca) excretion, have increased intestinal Ca absorption and bone Ca resorption and reduced renal Ca reabsorption, leading to increased UCa compared with the Sprague-Dawley (SD) rats. GHS rats have increased vitamin D receptors (VDR) at each of these sites, with normal levels of 1,25(OH)(2)D(3) (1,25D), indicatin...
Selenocysteine-incorporating tRNA(Sec)(UCA), the product of selC, was isolated from E.coli and aminoacylated with serine. The equilibrium dissociation constant for the interaction of Ser-tRNA(Sec)(UCA) with elongation factor Tu.GTP was determined to be 5.0 +/- 2.5 x 10(-8) M. Compared with the dissociation constants of the two elongator Ser-tRNA(Ser) species (Kd = 7 x 10(-10) M), the selenocyst...
This paper investigates how to efficiently charge sensor nodes in a wireless rechargeable sensor network (WRSN) with radio frequency (RF) chargers to make the network sustainable. An RF charger is assumed to be equipped with a uniform circular array (UCA) of 12 antennas with the radius λ, where λ is the RF wavelength. The UCA can steer most RF energy in a target direction to charge a specific W...
This study investigates differences and associations between urinary mineral concentrations and calcaneal bone measures assessed by quantitative ultrasonography (QUS) in 4322 children (3.1-11.9 years, 50.6% boys) from seven European countries. Urinary mineral concentrations and calcaneal QUS parameters differed significantly across countries. Clustering revealed a lower stiffness index (SI) in ...
BACKGROUND Filaggrin, coded by FLG, is the main source of several major components of natural moisturizing factor (NMF) in the stratum corneum (SC), including pyrrolidone carboxylic acid (PCA) and urocanic acid (UCA). Loss-offunction mutations in FLG lead to reduced levels of filaggrin degradation products in the SC. It has recently been suggested that expression of filaggrin may additionally b...
Background. Numerous studies conclude that about half of the asthmatic population is not well controlled. The aim of this study was to discuss causes, consequences and possible solutions of uncontrolled asthma (UCA). Methods. Discussion amongst asthma experts from the fields of Pneumology, Allergy and Primary Care, structured in three phases: 1) survey to get the opinion of participants involv...
Urocanic acid (UCA) derivatives were tested for their anti-inflammatory activity in inflammatory bowel disease (IBD) in two models: ex vivo and an experimental mouse model. Ex vivo: inflamed colonic tissue was incubated in culture medium with or without the UCA derivatives. Biopsies, incubated with UCA derivatives, produced lower levels of proinflammatory cytokines IL-6 and IL-8 as compared to ...
