Cyclic Redundancy-Check (CRC) codes are shortened binary cyclic codes that are widely used for error detection on digital communication links and data storage. Unfortunately, many of the standardized CRC polynomials provide less error detection capability than they might. In this work a survey on the published results about the error detection performance of CRC codes of up to 16 bit redundancy...

Rechargeable magnesium batteries (RMBs) have been considered a promising energy-storage device due to their high energy density and safety, but they still suffer from lack of high-rate performance cycle the cathode. Nanosized CuCo2S4/Cu7.2S4 composites synthesized for first time by facile solvothermal method. Herein, ion storage behavior when applied in cathode RMBs is discussed. Electrochemica...

The de novo evolution of proteins is now considered a frequented route for biological innovation, but the genetic and biochemical processes that lead to each newly created protein are often poorly documented. The common sunflower (Helianthus annuus) contains the unusual gene PawS1 (Preproalbumin with SFTI-1) that encodes a precursor for seed storage albumin; however, in a region usually discard...

A block tridiagonal matrix is factored with minimal fill-in using a cyclic reduction algorithm that is easily parallelized. Storage of the factored blocks allows the application of the inverse to multiple right-hand sides which may not be known at factorization time. Scalability with the number of block rows is achieved with cyclic reduction, while scalability with the block size is achieved us...

Graphene-decorated V2O5 nanobelts (GVNBs) were synthesized via a low-temperature hydrothermal method in a single step. V2O5 nanobelts (VNBs) were formed in the presence of graphene oxide, a mild oxidant, which also enhanced the conductivity of GVNBs. From the electron energy loss spectroscopy analysis, the reduced graphene oxide (rGO) are inserted into the layered crystal structure of V2O5 nano...

The copper oxide (CuO) nanowires/functionalized graphene (f-graphene) composite material was successfully composed by a one-pot synthesis method. The f-graphene synthesized through the Birch reduction chemistry method was modified with functional group "-(CH₂)₅COOH", and the CuO nanowires (NWs) were well dispersed in the f-graphene sheets. When used as anode materials in lithium-ion batteries, ...

This work reports on the concurrent electrochemical energy storage and conversion characteristics of granular copper oxide electrode films prepared using reactive radio-frequency magnetron sputtering at room temperature under different oxygen environments. The obtained films are characterized in terms of their structural, morphological, and compositional properties. X-ray diffraction, X-ray pho...

Nanorod-FeP@C composites are synthesized via a one-pot solution reaction of ferrocene (Fe(C5H5)2) with excess triphenylphosphine (PPh3) in sealed vacuum tubes at 390 °C, in which PPh3 is used as both the phosphorus source and solvent in the reaction. The structure and lithium storage performance of the as-prepared nanorod-FeP@C composites are intensively characterized, and it is interesting tha...

Monocyclic allylic cis-1,2-diols reacted with sulfuryl chloride at 0 °C in a regio- and stereo-selective manner to give 2-chloro-1-sulfochloridates, which were hydrolysed to yield the corresponding trans-1,2-chlorohydrins. At -78 °C, with very slow addition of sulfuryl chloride, cyclic sulfates were formed in good yields, proved to be very reactive with nucleophiles and rapidly decomposed on at...

objective: cell vital function has correlation with mechanical loadings that cell experiences. here, effects of in-vitro combined cyclic-static stretch on proliferation of human mesenchymal stem cell (hmsc) were evaluated. materials and methods: hmscs were cultured on gelatin coated elastic membranes, and exposed to stretch loading. four different regimes of cyclic, static, combined cyclic-sta...
