When searching for new gravitational-wave or electromagnetic sources, the $n$ signal parameters (masses, sky location, frequencies,...) are unknown. In practice, one hunts signals at a discrete set of points in parameter space, with computational cost that is proportional to number these points. If fixed, question arises, where should be placed space? The current literature advocates selecting ...

Abstract The new generation of artillery equipment is showing the development trend lightweight, long-range, intelligent et al. However, traditional mode based on physical prototype test cannot meet these needs development. In development, there are some problems, such as lack systematic guidance in overall design scheme, low degree digitalization and parameterization model, long period serial ...

A mesoporous g-C3N4 with guanidine hydrochloride as precursor was prepared by molten salt assisted hard template of silica (SiO2) aerogel for photocatalytic degradation tetracycline (TC). The study shows that the successfully synthesized presented a coral-like rod shaped and heptazine ring structure. When amount SiO2 1.4 g, lower band gap (2.31 eV) sample (GM-1.4) interfacial resistance display...

An in-situ template formation method is reported for the synthesis of hierarchically porous carbon (PC), with La and Fe nitrates as precursors citric acid precursor. During carbonization, oxides, originated from metal nitrates, move together react each other to form LaFeO3 particles, serving hard PC. Thus, three types pores are generated in PC through (1) release gases, (2) movement oxides (3) ...

dye sensitized solar cell was fabricated from a double layer photoanode. first, tio2 nanoparticles  were synthesized by hydrothermal method. these tio2 nps were deposited on fto glasses by electrophoretic deposition  method in applied voltage of 5 v and epd time of 2.5-10 min. then tio2 hollow spheres (hss) were synthesized by sacrificed template method with carbon spheres as template and ttip ...

In the current research project, sol-gel electrophoresis technique was utilized to grow titanium dioxide (TiO2) nanotubes. A titanium sol was prepared using organometallic precursors of titanium to fill the template channels. The prepared solwas driven into nanopores of porous anodic aluminum oxide templates under the influence of a DC electric field to form nanotubes on the pore walls. Tube fo...

leiomyoma is a rare benign neoplasm deriving from smooth muscle. vascular leiomyoma is its most common subtype in the oral cavity. it may appear at any age with the greatest incidence in the 4th and 5th decade of life. the common manifestation is a slow-growing, asymptomatic, submucousal mass. the diagnosis is only through microscopic examination requiring special staining. treatment of choice ...
