We study the modifications of synchrotron radiation of charges in a storage ring as they are cooled. The pair correlation lengths between the charges are manifest in the synchrotron radiation and coherence effects exist for wavelengths longer than the coherence lengths between the charges. Therefore, the synchrotron radiation can be used as a diagnostic tool to determine the state (gas, liquid,...

The sphere optimization program sphopt was originally written as a sequential program using lapack, and was converted to use scalapack, primarily to overcome memory limitations. The conversion was relatively straightforward, using a small number of organizing principles which are widely applicaple to the scalapack parallelization of serial code. The main innovation is the use of a compressed bl...

Saturated and unsaturated fatty aldehydes were prepared in good yield by the reduction of acid chlorides with lithium aluminum tri-t-butoxy hydride. Saturated odd and even numbered aldehydes were prepared by the ozonolysis-reduction of 1-alkenes. Ozonides were hydrogenated with a Lindlar catalyst or reduced with dimethyl sulfide. Several diols, including 1,3-propanediol and ethylene glycol, wer...

Dispersed porcine parathyroid cells were incubated at calcium concentrations between 0.5 and 3.0 mM in the presence of 3H- or 14C-amino acids to label newly synthesized parathormone. Up to four times more hormone was secreted at the lower calcium concentration but its specific radioactivity, from 30 to 50 times that of the intracellular pool, did not change. Dibutyrl cyclic AMP doubled immunoac...

Oxidative stress plays a pivotal role in the pathogenesis of many diseases, but there is no accurate measurement oxidative or antioxidants that has utility clinical setting. Cyclic Voltammetry an electrochemical technique been widely used for analyzing redox status industrial and research settings. It also recently applied to assess antioxidant vivo biological samples. This systematic review id...

Muscles not only generate force. They may act as springs, providing energy storage to drive locomotion. Although extensible myofilaments are implicated as sites of energy storage, we show that intramuscular temperature gradients may enable molecular motors (cross-bridges) to store elastic strain energy. By using time-resolved small-angle x-ray diffraction paired with in situ measurements of mec...

For the characteristics of large number, fast change, high cost of random access of data stream, this paper proposes a Bayesian classification data mining algorithm based on incremental storage tree to handle the problems. Use sliding window to process data stream and divide it into several basic units, apply Principal component analysis (PCA) to compress the data from window and produce dynami...

Supercapacitor (SC) is an energy storage technology that bridges the gap between conventional capacitors and rechargeable batteries. Emerging nano-architectured carbon–metal oxide composites are promising for electrode designs for supercapacitors due to their unique strategy utilizing electrochemical double-layer capacitance (EDLC) and pseudo-capacitance together in single cell to optimize the ...
