We study the coherence trapping of a qubit correlated initially with a non-Markovian bath in a pure dephasing channel. By considering the initial qubit-bath correlation and the bath spectral density, we find that the initial qubit-bath correlation can lead to a more efficient coherence trapping than that of the initially separable qubit-bath state. The stationary coherence in the long time limi...

Novel classes of synthetic drugs, including synthetic cathinones ("bath salts") and synthetic cannabinoids ("spice" or "K2"), have recently emerged as popular drugs of abuse. Salvia divinorum, a naturally occurring herb, has gained popularity in the last decade as a hallucinogenic as well. The legal status of these substances has been undergoing rapid changes and has been confusing to lawmakers...

Powders of silver sulfide have been synthesized by chemical bath deposition from aqueous solutions of silver nitrate and sodium sulfide in the presence of sodium citrate or EDTA-H2Na2. Colloid solutions have been prepared by a chemical condensation method from the same aqueous solutions. Synthesized silver sulfide nanopowders have a monoclinic (space group P21/c) acanthite-type structure but th...

Pica refers to the persistent, compulsive craving for and ingestion of nonfood items and certain food items. Pica is quite common among dialysis patients. The nutrient composition of some of the substances ingested may contribute to severe metabolic and mineral disturbances and other serious medical complications. We report the first case of a hemodialysis patient with chalk pica associated hyp...

The conventional rinsing after bleaching to remove the residual hydrogen peroxide, harmful to the dyes either in solution or on the fabric, was replaced by enzymatic cleaning using catalases. The catalasetreated bleaching liquor was reused for dyeing. Though no hydrogen peroxide was detected after the enzymatic process, the bleaching bath composition caused unacceptable colour changes on dyed f...

Nickel-tungsten alloys were electrodeposited on stationary working electrodes from a nickel sulfate, sodium tungstate, and tri-sodium citrate-based bath under different operating conditions. The microstructure of the deposits was studied by X-ray diffraction, the morphology by scanning electron microscopy and atomic force microscopy, and the approximate composition by energy dispersive spectros...

In this work, Sn-Cu composite powders were produced using an electroless process. The tin content on the surface of copper powders was varied by using di erent concentrations of SnSO4 in the plating bath. The surface morphology of the produced Sn-Cu composite powders was characterized using scanning electron microscopy (SEM). Energy dispersive spectroscopy (EDS) was used to determine the elemen...

Drawing lessons from the development of cities at home and abroad success and lost experience, through practice research, this paper systemically analysis the evolution of urban economy space. In the scope of global industrial supply chain’s recomposing, it is discusses that modern city’s function structure characteristic, focusing “integrative logistics management service”. According to Dalian...

As traditional competition becomes global, businesses fail to take, on their own, the measures that are required to become more competitive. Hence, in a globally competitive environment, national improvement and competitiveness have also become vital. Businesses must utilize and be supported by the international competitiveness of their nations. This study aims to analyze the competitiveness of...
