We calculate accurate potential energy curves for HeO(-), NeO(-), and ArO(-), including the full counterpoise correction and allowing for spin-orbit effects. Comparison with previous curves is presented, where these are available. The three curves, (2)Sigma(12) (+), (2)Pi(12), and (2)Pi(32), are used to derive spectroscopic constants and to calculate the transport coefficients for O(-) moving i...
The psychophysical detection threshold of a low-frequency tone masked by broadband noise is reduced by < or = 15 dB by inversion of the tone in one ear (called the binaural masking level difference: BMLD). The contribution of 120 low-frequency neurons (best frequencies 168-2,090 Hz) in the inferior colliculus (ICC) of the guinea pig to binaural unmasking of 500-Hz tones masked by broadband nois...
We previously established a functional pathway extending from the superficial layers of the superior colliculus (SC) through the inferior pulvinar (PI) to cortical area MT in the primate (Macaca mulatta). Here, we characterized the signals that this pathway conveys to cortex by recording from pulvinar neurons that we identified by microstimulation as receiving input from SC and/or projecting to...
The mechanism for the formation of $\Lambda(1405)$ resonance is studied in a chiral quark model that includes quark-meson as well contact (four point) interactions. negative-parity $S$-wave scattering amplitudes strangeness $-1$ and $1$ are calculated within unified coupled-channel framework $KN$, $\bar{K}N$, $\pi\Sigma$, $\eta\Lambda$, $K\Xi$, $\pi\Lambda$, $\eta\Sigma$ channels possible genui...
The Faddeev equations for the $\Xi NN$ bound-state problem are solved where three $S$=$-2$ baryon-baryon interactions of J\"ulich-Bonn-M\"unchen chiral EFT, HAL QCD and Nijmegen ESC08c used. $T$-matrix $T_{\Xi N, \Xi N}$ obtained within original $\Lambda\Lambda$-$\Xi N$-$\Sigma\Sigma$ $/$ N$-$\Lambda \Sigma$-$\Sigma\Sigma$ coupled-channel framework is employed as an input to equations. We found...
In this paper a discrete competitive neural network is introduced to calculate the optimal robot arm movements for processing a considered commitment of tasks, using the branch and bound methodology. A special method based on the branch and bound methodology, modified with a travelling path for adapting in the neural network, is introduced. The main neural network of the system consists of diff...
A refined investigation on light flavor meson-baryon scatterings is performed using a dynamical coupled-channel approach, the J\"ulich-Bonn model, that respects unitarity and analyticity constraints. The channel space of $\ensuremath{\pi}N$, $\ensuremath{\pi}\mathrm{\ensuremath{\Delta}}$, $\ensuremath{\sigma}N$, $\ensuremath{\rho}N$, $\ensuremath{\eta}N$, $K\mathrm{\ensuremath{\Lambda}}$, $K\ma...
The rovibronic structure of A$^2\Sigma^+$, B$^2\Pi$ and C$^2\Pi$ states nitric oxide (NO)is studied with the aim producing comprehensive line lists for its near ultraviolet spectrum. Empirical energy levels three electronic are determined using a combination empirical MARVEL procedure ab initio calculations, available experimental data critically evaluated. Abinito methods which deal simultaneo...
We present neutron scattering from the flux line lattice (FLL) in MgB2. Between 0.5 and 0.9 T the FLL undergoes a 30 degrees reorientation, and simultaneously the scattered intensity falls sharply consistent with the weaker superconducting pi band being suppressed with increasing field. We speculate that the pi and sigma bands favor different FLL orientations, and that the reorientation is driv...
The Ti:Saphire laser operated within 13800 - 11800 cm$^{-1}$ range was used to excite the $c^3\Sigma^+$ state of KCs molecule directly from ground $X^1\Sigma^+$ state. laser-induced fluorescence (LIF) spectra $c^3\Sigma^+ \rightarrow a^3\Sigma^+$ transition were recorded with Fourier-transform spectrometer 8000 10000 range. Overall 673 rovibronic term values belonging both $e/f$-components $c^3...
