human serum albumin (hsa) is the most abundant protein constituent of blood plasma. this protein consists of a single polypeptide chain of 585 amino acid residues, which has many important physiological functions. hsa can bind and carry many drugs, including anticoagulants, tranquilizers, and general anesthetics. some technique such as: fluorescence spectroscopy, three-dimensional fluorescence ...
In this study, the change of porosity and roughness of carbon nanostructures, including fullerenes, carbon nanotubes and graphene was investigated according to oxidation process. The effect of oxidation was more sensible on smoother surface of nanostructures. Oxidation increases surface roughness of graphene up to 5.2% and porosity up to 35.2%. While, roughness of hummers graphene is 13....
A two dimensional mathematical model has been developed for describing the temperature, flow, and electric fields in the are column of the Gas Metal Arc Welding (GMAW) of aluminum in argon shielding gas using axisymmetric Navier-Stokes, Maxwell, and differential thermal energy equations. The predicted results are most sensitive to the cathode spot radius and an optimum cathode spot radius exist...
This article considers change-point testing and estimation for a sequence of high-dimensional data. In the case mean shift independent data, we propose new test which is based on U-statistic in Chen Qin (Ann. Statist. 38 (2010) 808–835) utilizes self-normalization principle (Shao J. R. Stat. Soc. Ser. B. Methodol. 72 343–366; Shao Zhang Amer. Assoc. 105 1228–1240). Our targets dense alternative...
