Graphene (Gr)/metal oxide nanocomposites, as advanced electrode materials, have drawn significant attention in supercapacitors due to their two components' synergistic cooperation, which compensates each other's drawbacks and hence perform better than individual components. In this study, graphene/metal Gr/NiO Gr/Co3O4 binaries were separately synthesized by a co-precipitation method NiO or Co3...

in interventional or observational longitudinal studies, the issue of missing values is one of the main concepts that should be investigated. the researcher's main concerns are the impact of missing data on the final results of the study and the appropriate methods that missing values should be handled. regarding the role and the scale of the variable that missing values have been occurred and ...

objective(s): the aim of this work was to investigate the effect of the natural and the chemically modified form of cyclodextrins namely; β-cyclodextrin (β-cd) and hydroxypropyl-β-cyclodextrin (hp-β-cd) respectively on the solubility and dissolution rate of aripiprazole; an antipsychotic medication showing poor aqueous solubility.   materials and methods: phase solubility of aripiprazole with t...

in this paper, a new method is introduced for improving the efficiency of the residue number system, which uses both binary and residue representations in order to represent a number. a residue number system uses the remainder of the division in several different modules. conversion of a number to smaller ones and carrying out parallel calculations on these numbers greatly increase the speed of...

It is well-known that, given inorder traversal along with one of the preorder or postorder traversals of a binary tree, the tree can be determined uniquely. Several algorithms have been proposed to reconstruct a binary tree from its inorder and preorder traversals. There is one study to reconstruct a binary tree from its inorder and postorder traversals, and this algorithm takes running time of...

We present new links between some remarkable martingales found in the study of the Binary Search Tree or of the bisection problem, looking at them on the probability space of a continuous time binary branching process.

some drugs have low bioavailability due to their poor aqueous solubility and/or slowdissolution rate in biological fluids. stiripentol (stp) is a novel anticonvulsant drug that isstructurally unrelated to the currently available antiepileptics. it has poor aqueous solubilityand its solubility has to be enhanced accordingly. polyethyleneglycol 6000 (peg-6000) iscommonly utilized as a hydrophilic...

Decoherence in superconducting qubits has long been attributed to two-level systems arising from the surfaces and interfaces present real devices. A recent significant step reducing decoherence was replacement of niobium by tantalum, resulting a tripling transmon qubit lifetimes (T1). The identity, thickness, quality native surface oxide, is thought play major role, as tantalum only one oxide w...
