In order to conduct faithful simulations of ocean circulation one needs considerable computational power and storage capabilities. We study the parallelization of a three-dimensional ocean circulation model (OCM) and provide summary results from recent experiments on the Cedar hierarchical architecture. A major goal of our effort is to obtain guidelines for the proper design of OCM codes for pa...

PURPOSE Studies comparing radical prostatectomy (RP) outcomes with those of radiotherapy with or without androgen deprivation therapy (RT±ADT) for prostate cancer (PCa) have yielded conflicting results. Therefore, we used propensity score-matched analysis and competing risk regression analysis to compare cancer-specific mortality (CSM) and other-cause mortality (OCM) between these two treatment...

BACKGROUND Alterations in one-carbon metabolism (OCM) have been observed in patients with schizophrenia (SZ), but a comprehensive study of OCM has not yet been conducted. A carbon atom is transferred from l-serine to methionine during OCM, but the relationship between l-serine and methionine in SZ is not yet known. We investigated the relationship between l-serine and methionine to obtain a com...

the oxidative coupling of methane (ocm) over m-na-mn/sio2 catalysts (m=w, cr, nb and v) was investigated using a continuous-flow quartz reactor at 775°c, 1 atm and 100 cm3min-1 gas flow rates, and correlated with the observed structure and redox properties.the interaction effects of the metal-metal and metal-support on the methane conversion and c2+ yield were investigated using x-ray diffracti...

This paper presents main ideas and design details of a performance analysis tool – G-PM and a grid application monitoring system – OCM-G for applications running on the Grid which are under development within the EU CrossGrid project. Besides of the operation of G-PM’s components, we overview its internal interfaces. G-PM enables not only standard measurements, but also comprises application-sp...

A central goal of neuroscience is to understand how groups of neurons interact to give rise to the myriad functions of the nervous system. This task is extremely difficult in part because of the technical challenge of recording the electrical activity of many neurons simultaneously without disturbing their environment. Although several methods exist, new techniques are in strong demand. One pro...

We demonstrate how optical coherence imaging techniques can detect intrinsic scattering changes that occur during action potentials in single neurons. Using optical coherence tomography (OCT), an increase in scattering intensity from neurons in the abdominal ganglion of Aplysia californica is observed following electrical stimulation of the connective nerve. In addition, optical coherence micro...

In this contribution the solution of Fractional Optimal Control Problems (FOCP) by using Orthogonal Collocation Method (OCM) and Multi-objective Optimization Stochastic Fractal Search (MOSFS) algorithm is investigated. For purpose, three classical case studies on engineering are considered. Initially, concentration profiles laccase enzyme production process analyzed to evaluate influence fracti...

CH4, C2H6 and C2H4 are the most important outlet gaseous of oxidative couple methane (OCM) reaction and this process is a new technology for conversion of natural gas to ethane and ethylene products. In this study, adsorption of OCM outlet hydrocarbons over 10X zeolite has been examined at equilibrium conditions. Temperature and pressure are the most effective operational parameters in the batc...

Understanding the mechanism of angiogenesis could help to decipher wound healing and embryonic development and to develop better treatment for diseases such as cancer. Microengineered devices were developed to reveal the mechanisms of angiogenesis, but monitoring the angiogenic process nondestructively in these devices is a challenge. In this study, we utilized a label-free imaging technique, u...
