RATIONALE Proper patterning of the atrioventricular canal (AVC) is essential for delay of electrical impulses between atria and ventricles, and defects in AVC maturation can result in congenital heart disease. OBJECTIVE To determine the role of canonical Wnt signaling in the myocardium during AVC development. METHODS AND RESULTS We used a novel allele of β-catenin that preserves β-catenin's...

We address the arbitrarily varying channel (AVC) with colored Gaussian noise. The work consists of three parts. First, we study general discrete AVC fixed parameters, a model that combines and time-varying channel. determine both deterministic code capacity random capacity. Super-additivity is demonstrated, showing can be strictly larger than weighted sum parametric capacities. In second part, ...

BACKGROUND Previous epidemiologic studies have shown that low-density lipoprotein is an independent risk factor for prevalent aortic valve calcification (AVC); however, to our knowledge, the interactions between plasma lipoprotein concentrations and age on the relative risks (RRs) for AVC prevalence and severity have not been examined in a large, racially and ethnically diverse cohort. METHOD...

The responses to the Call for Proposals on Scalable Video Coding Technology (N6193) documented in [1] proved the existence of techniques that exhibit promising coding efficiency combined with functionalities of temporal, spatial, and SNR scalability. A class of proposals are based on the state-of-the-art AVC video coding standard [2]. One of the proposals that showed a coding efficiency nearly ...

Mutations in Notch2, Jagged1 or homologs of the Hairy-related transcriptional repressor Hey2 cause congenital malformations involving the non-chamber atrioventricular canal (AVC) and inner curvature (IC) regions of the heart, but the underlying mechanisms have not been investigated. By manipulating signaling directly within the developing chick heart, we demonstrated that Notch2, Hey1 and Hey2 ...

The extension of H.264/AVC hybrid video coding towards motion-compensated temporal filtering (MCTF) and scal-ability is presented. Utilizing the lifting approach to implement MCTF, the motion compensation features of H.264/AVC can be re-used for the MCTF prediction step and extended in a straightforward way for the MCTF update step. The MCTF extension of H.264/AVC is also incorporated into a vi...

The development of intelligent control approaches for vibration reduction of flexible plate structures are investigated and reported in this thesis. In this work active intelligent control comprises a set of control techniques based on particle swarm optimisation (PSO), real coded genetic algorithm (RCGA) and artificial immune system (AIS). A traditional method of recursive least squares ( U S ...

in this work firstly fe3o4 nanoparticles were synthesized via a sono-chemical method. at the second step magnesium hydroxide shell was synthesized on the magnetite-core under ultrasonic waves. for preparation fe3o4-mgo the product was calcinated at 400 ºc for 2h. properties of the product were examined by x-ray diffraction pattern (xrd), scanning electron microscope (sem) and fourier transform ...
