Transmission of bacterial infections to healthcare workers during intubation and respiratory care of patients with severe pneumonia
Exposure of healthcare workers to patients with rapidly fatal infections invariably raises concerns regarding the risk of occupational acquisition. We describe acquisition of Streptococcus pyogenes by 2 nurses from a patient with fatal pneumonia and review previously reported cases of transmission of bacterial pathogens from patients with pneumonia to healthcare workers

First case of bloodstream infection caused by rhodococcus erythropolis
We describe the first case of bloodstream infection caused by Rhodococcus erythropolis. The identification was performed using 16S rRNA sequencing. This case illustrates that non-equi Rhodococcus infections may be underdiagnosed due to difficulties in identification in the routine clinical microbiology laboratory
Theory of Slow Light Enhanced Four-Wave Mixing in Photonic Crystal Waveguides
The equations for Four-Wave-Mixing in a Photonic Crystal waveguide are
derived accurately. The dispersive nature of slow-light enhancement, the impact
of Bloch mode reshaping in the nonlinear overlap integrals and the tensor
nature of the third order polarization are therefore taken into account.
Numerical calculations reveal substantial differences with simpler models,
which increase with decreasing group velocity. We predict that the gain for a
1.3 mm long, unoptimized GaInP waveguide will exceed 10 dB if the pump power
exceeds 1 W.Comment: 6 pages, 4 figures; submitted to Optics Expres

First-principles study on the energetics and vibrational properties of the S2 - impurity in alkali-halide crystals
金沢大学大学院自然科学研究科計算科学金沢大学理学部We have performed first-principles electronic structure calculations for the S2 and S2- molecules in the vacuum and found that the calculated equilibrium bond lengths and vibrational spectroscopic constants are in good agreement with the experiments as well as the previous calculations. Based on this conformation we extended these calculations to the substitutional S2- molecule in the alkali halides, such as NaCl, NaBr, NaI, KCI, KBr, KI, RbCl, RbBr, and RbI. It is found from these calculations that the S2- center aligned to [110] direction is generally favorable over those with the [100] and [111] orientations, in agreement with the experiments. We also found that the vibrational frequencies of the S2- anion in the alkali halides shift to higher energies with decreasing lattice parameters. These results suggest that the change in the bond length of the S2- anion in the matrices depends on the species of halogen atom, while the frequencies are influenced by the species of alkali atom
Development of a shutterless continuous rotation method using an X-ray CMOS detector for protein crystallography
A shutterless continuous rotation method using an X-ray complementary metal-oxide semiconductor (CMOS) detector has been developed for high-speed, precise data collection in protein crystallography. The new method and detector were applied to the structure determination of three proteins by multi- and single-wavelength anomalous diffraction phasing and have thereby been proved to be applicable in protein crystallography
