Abstract—Atrial fibrillation (AF) is the most frequent cardiac arrhythmia seen in clinical practice. Several therapeutical approaches have been developed to terminate the AF and the effects are evaluated by the reduction of the wavelet number after the treatments. Most of the previous studies focus on modeling and analysis of the mechanism, and the characteristic of AF. But no one discusses a…
Utilizing small (e.g., 4KB) pages incurs frequent TLB misses on modern big memory applications, substantially degrading the performance of the system. Large (e.g., 1GB) pages or direct segments can alleviate this penalty due to page table walks, but at the same time such a strategy exposes the organizational and operational details of modern DRAM-based memory systems to applications. Row-buffer…
A B S T R A C T Carbon nanotubes (CNTs) were used as the electric double layer capacitor (EDLC) material and were synthesized by using thermal chemical vapor deposition (TCVD). To enhance the EDLC capacity, the ruthenium dioxide (RuO2) nanorods were grown on CNTs by using metal organic chemical vapor deposition (MOCVD). The synthesized CNTs were the principal part and template, and the RuO2…
Background and Aims Phosphorus deficiency is a major limiting factor for crop yield worldwide. Previous studies revealed that PHR1 and it homologues play a key role in regulating the phosphate starvation response in plants. However, the function of PHR homologues in common wheat (Triticum aestivum) is still not fully understood. The aim of the study was to characterize the function of PHR1 ge…
Abstract. Highly hydroxylated barium titanate (BaTiO3) nanoparticles have been prepared via an easy and gentle approach which oxidizes BaTiO3 nanoparticles using an aqueous solution of hydrogen peroxide (H2O2). The hydroxylated BaTiO3 surface reacts with sodium oleate (SOA) to form oleophilic layers that greatly enhance the dispersion of BaTiO3 nanoparticles in organic solvents such as tetr…
Abstract. Zr-containing mesoporous molecular sieves were synthesized by hydrothermal method using cetyltrimethyl ammonium bromide as a template and sodium silicate and zirconium sulfate as raw materials. The structure and morphology of the synthesized samples were characterized via various physicochemical methods, including X-ray diffraction (XRD), transmission electron microscopy (TEM), F…
Abstract. Polychlorinated biphenyls spiked in soil can be extracted by a continuous flow supercritical fluid carbon dioxide system and converted on-line to bicyclohexyl using a polymer-stabilized palladium nanoparticle catalyst. The catalytic hydrodechlorination of 4-chlorobiphenyl to biphenyl follows a pseudo-first-order reaction kinetics. The subsequent hydrogenation of biphenyl to bicycl…
Abstract The effect of adding Pt to a Pd/SiO2 catalyst for the direct formation of H2O2 in ethanol that contains H2SO4 and halide ions (Cl or Br) has been investigated. The addition of only 5 atom% Pt to a catalyst that contained 0.5 wt.% Pd resulted in a 2.5-fold increase in the rate of peroxide formation with only a small decrease in selectivity. The addition of substantially more Pt cause…
