First-principles study on 3 d transition-metal dihydrides

Abstract: The ultrasoft pseudopotential calculations are performed for the ${\mathrm{CaF}}_{2}$-type dihydrides ${\mathrm{TiH}}_{2},$ ${\mathrm{VH}}_{2},$ and ${\mathrm{CrH}}_{2}.$ The calculated lattice constants agree well with the experimental data except for ${\mathrm{CrH}}_{2}.$ We also perform calculations for a solution of hydrogen in Fe and Ni and obtain the site preferences correctly. The results for the heats of formation and heats of solution show that the calculations give the correct trends for exothermic through endothermic reactions but overbind hydrogen with transition metals, typically about $20 {\mathrm{k}\mathrm{J}/\mathrm{m}\mathrm{o}\mathrm{l}\mathrm{}\mathrm{H}}_{2}.$ This overbinding is improved by including the zero-point energy correction. The energetics of binary dihydrides including hypothetical ${\mathrm{FeH}}_{2}$ and ${\mathrm{NiH}}_{2}$ is discussed in term of three contributions: namely, the structural transformation energy, the lattice expansion energy, and the hydrogen insertion energy. The former two contributions are understood from the nature of the host metals. The hydrogen insertion energy can be represented by a simple geometric model. The extension of this model is also suitable for alloy dihydrides.

Inter-vehicle drowsy driver advisory system

Abstract: A driver advisory system is provided for use in a host vehicle and for transmitting to drivers of other vehicles information regarding the status of a driver of the host vehicle. The driver advisory system includes a sensor, a first processor and a communication unit. The sensor monitors a physical condition of the driver of the host vehicle. The sensor provides an output quantifying the physical condition of the driver of the host vehicle. The first processor receives the output provided by the sensor. The first processor calculates a risk factor as a function of the output provided by the sensor. The first processor provides an output signal having information concerning the condition of the driver of the host vehicle in response to the risk factor exceeding a predetermined threshold value. The communication unit receives the output signal from the first processor and transmitting the information for retrieval by the other vehicles in the vicinity of the host vehicle.

Rapid Detection of Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma parvum, and Ureaplasma urealyticum Organisms in Genitourinary Samples by PCR-Microtiter Plate Hybridization Assay

Abstract: We present a method for detecting the presence of Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma parvum, and Ureaplasma urealyticum organisms, which are thought to be associated with nongonococcal urethritis (NGU) and other genitourinary infections, in clinical samples. This method consists of PCR amplification of a part of the 16S rRNA gene followed by 96-well microtiter plate hybridization assay using four species-specific capture probes to detect the targets. To test the efficacy of this method, we applied it to the detection of the four species in the urine of patients with NGU. There were no cross-reactions with other human mycoplasmas or ureaplasmas, and the PCR-microtiter plate hybridization assay detected as few as 10 copies of the 16S rRNA gene of each of the four species. Based on these results, this PCR-microtiter plate hybridization assay can be considered an effective tool for the diagnosis of genitourinary infections with mycoplasmas or ureaplasmas.
