The regions from positions 1391 to 1545 and 1620 to 1865 (Escherichia coli numbers) of the 23S ribosomal DNA sequences have been analyzed for a number of Pseudomonas fluorescens and P. putida isolates. Variability was observed only in three smaller regions from positions 1484 to 1508, 1531 to 1542, and 1714 to 1748, corresponding to helices 58, 59, and 63, respectively, where up to 53% dissimil...

We report on realization of channel plasmon-polariton (CPP) propagation along a subwavelength metal groove. Using imaging with a near-field microscope and end-fire coupling with a tapered fiber connected to a tunable laser at telecommunication wavelengths (1425-1620 nm), we demonstrate low-loss (propagation length approximately 100 microm) and well-confined (mode width approximately 1.1 microm)...

C15H16N2S is monoclinic [orthorhombic], P2(1)/c [Pbcn]. Unit-cell dimensions at 293 K are a = 9.506(1), b = 7.629(1), c = 20.077(1)A, beta = 99.93(1) degrees, V= 1434.2(2)A(3), D(x) = 1.187 g/cm3, and Z = 4 [a = 11.806(2), b = 13.954(2), c = 8.466(1)A, V = 1394.7(3)A(3), D(x) = 1.221 g/cm3, and Z = 8]. The R value is 0.049 [0.045] for 1620 [1229] observed reflections. The dihedral angle between...

The field of vital statistics is as open to investigation, analysis and experimentation as it was three hundred years ago when John Graunt (1620 -1674) introduced the observations on the London Bills of Mortality. The research possibilities are sometimes overlooked by statisticians and demographers because the registration systems now established in developed countries seem routinized and steri...

In the QCD sum rule approach we predict the Σ (1620) mass by considering the K̄N , πΣ, and πΛ multiquark interpolating fields (I=1). The predicted mass is about 1.592 GeV. We also obtain 1.424 GeV as the Λ (1405) mass from the πΣ+πΣ+πΣ multiquark state (I=0), and compare this with our previous result from the πΣ multiquark state. On the other hand, the mass from the K̄N multiquark state (I=0) is ...

A radically revised ATC (Air Traffic Control) interface, developed from that described at HCI-Aero98, has been evaluated by trials using 26 postgraduate students (native French speakers). Twenty-four out of 26 students were able to control traffic at a nominal rate of 200 aircraft per hour after about one hour of training. All but two of 1620 potential conflicts were resolved correctly. All but...
