We study the dynamics of condensate formation in an inhomogeneous trapped Bose gas with a positive interatomic scattering length. We take into account both the nonequilibrium kinetics of the thermal cloud and the Hartree-Fock mean-field effects in the condensed and the noncondensed parts of the gas. We solve our equations numerically by assuming that the thermal component behaves ergodically an...

This thesis has been motivated by intracellular transport phenomena, such as kinesins and myosins moving along cytoskeletal filaments or ribosomes along messenger RNA. In both cases molecular motors move uni-directionally along a one-dimensional track. This motion is driven by the free energy released in the chemical hydrolysis reaction of ATP (adenosine-triphosphate). It drives conformational ...

In 2005, we have made further progress in the studies of atom correlations in one-dimensional (1D) Bose gases [1]. We have calculated the density profiles and density correlation functions of a harmonically trapped (nonuniform) 1D Bose gas, using the exact finite-temperature solutions for the uniform case and applying a local density approximation. The results are valid for a trapping potential...

Tropospheric ozone, lot-med from nonlinear reactions between VOC5 and nitrogen oxides (NOr), is a primarr constituent of urban smog (1). Estimates of VOC control costs needed to attain the National Ambient Air Quality Standard (NAAQS) for ozone of 0.12 parts per million are on the order of billions of dollars per year, and in the most severely impacted region~, the necessary control technologie...

Over the past decade there has been renewed interest within AI in building simple autonomous ’creatures’ as a way of investigating mechanisms underlying the generation of adaptive behaviour [4, 1]. The vast majority of researchers in this field use some form of artificial neural network (ANN) as the basis of the ’nervous system’ of their agents. These networks can be envisaged as simple nodes c...

The heat resistance of dry bacterial spores was tested in various gases at temperatures ranging from 121.1 to 160 C (250 to 320 F). Spores of Clostridium sporogenes (PA 3679) were heated in air, carbon dioxide, and helium; spores of Bacillus subtilis 5230 were heated in these gases and also in oxygen and in nitrogen. The surrounding gas influenced the heat resistance, but the differences among ...

Noble gases seem to have no significant effect on the anesthetic targets due to their simple, spherical shape. However, xenon has strong narcotic efficacy and can be used clinically, while other noble gases cannot. The mechanism remains unclear. Here, we performed molecular dynamics simulations on phospholipid bilayers with four kinds of noble gases to elucidate the difference of their effects ...

In this paper we report a newly developed technique - laser calorimetry spectroscopy (LCS), which is a combination of laser absorption spectroscopy and calorimetry - for the detection of gases dissolved in liquids. The technique involves determination of concentration of a dissolved gas by irradiating the liquid with light of a wavelength where the gas absorbs, and measuring the temperature cha...

BACKGROUND Capnography provides a continuous, non-invasive monitoring of the CO2 to assess adequacy of ventilation and provide added safety features in mechanically ventilated patients by allowing for quick identification of unplanned extubation. These monitors may allow for decreased utilization of blood gases. The objective was to determine if implementation of continuous capnography monitori...
