In the recent experiments like DIS at HERA or the heavy-ion experiments at RHIC, and also in expected LHC at CERN, the number of involved partons is very large, due to the high energy and/or the high number of participants of those experiments. These high parton densities should in principal lead to an extremely huge multiparticle production, but experimentally we have seen that this is not the...

results roc-derived spo2 threshold of ≤ 94% can predict hypoxemia (pao2 < 60 mmhg) with a sensitivity of 100% and a specificity of 95%. furthermore, there are associations between the roc-derived spo2 threshold of ≤ 97% and detection of hypoxemia (pao2 < 70 mmhg) with a sensitivity of 100% and a specificity of 46%. the accuracy of pulse oximetry was not affected by the severity of liver disease...

background: it was hypothesized that the use of pentoxifylline would increase arterial o2 saturation and increase exercise tolerance in patients with chronic obstructive pulmonary disease (copd). methods: we tested this hypothesis in 23 patients with copd and pulmonary hypertension. patients were randomized to receive pentoxifylline or placebo, each for a 12-week period, in a prospective, doubl...

the process of adaptation to cold is an important mechanism in wheat cultivars to tolerate cold stress. this work was aimed to calrify the relationship between vernalization requirement with cold tolerance by assessing physiological changes in cold susceptible spring and tolerant winter wheat (triticum aestivum, cvs. kohdasht and cheyyene, respectively) in environmentally controlled conditions,...

We have investigated the effect of key solar wind driving parameters on solar wind-magnetosphere coupling efficiency during sheath and magnetic cloud-driven storms. The particular focus of the study was on the coupling efficiency dependence with Alfvén Mach number (MA). The efficiency has been estimated using the dawn-dusk component of the interplanetary electric field (EY ), Newell and Borovsk...

this paper is a report on the synthesis of the fe3o4@ag core-shell with high saturation magnetization of magnetite nanoparticles as the core, by using polyol route and silver shell by chemical reduction. x-ray diffraction (xrd) and fourier transform infrared spectroscopy analyses confirmed that the particles so produced were monophase. the magnetic properties of the product were investigated by...

there are fewer problems encountered with optical voltage transducers in comparison with their inductive and capacitive counterparts. although capacitive and inductive transformers are used vastly for the purpose of measurement and protection in the networks, they cause problems such as core saturation and improper transient responses which decrease the accuracy of measurement and eficiency of ...

We compared seven techniques, commonly used for detection of amniotic fluid phospholipids in thin-layer chromatography, with respect to their sensitivity to saturation of the fatty acid carbon-chain of lecithin. The techniques fell into two classes: sensitive and insensitive; those classed as saturation sensitive were less than or equal to 10% as sensitive to fully saturated lecithin as to leci...

In this paper, we propose a saturation binary neuron model and use it to construct a Hopfield-type neural network called saturation binary neural network to solve the bipartite sub-graph problem. A large number of instances have been simulated to verify the proposed algorithm, with the simulation result showing that our algorithm finds the solution quality is superior to the compared algorithms.
