Although all fishes have a mechanosensory lateral line system – a system of water flow detectors (neuromasts) in canals or free on the skin's surface – particular behavioral functions are documented for only a few species. Work on lateral line use for feeding has focused on either cavefishes or night-active species (Montgomery, 1989). While surface-feeding(More)
The Io-Jupiter S-bursts are series of quasi-periodic impulsive decameter radio emissions from the magnetic flux tube connecting Jupiter to its closest galilean satellite Io. This paper discusses the possibility, suggested by previous works by Hess et al, that the S-bursts are triggered by upgoing electrons accelerated (downward) by trapped Alfvén waves,(More)
PACS 03.70+k theory of quantized fields Abstract: After a short recall of our previous standing wave approach to the Casimir force problem, we consider Lifshitz's temperature Green's function method and its virtues from a physical point of view. Using his formula, specialized for perfectly reflecting mirrors, we present a quantitative discussion of the(More)
The K luminosity-metallicity relation for dwarf galaxies and the tidal dwarf galaxies in the tails of HCG 31 ABSTRACT We determine a K-band luminosity-metallicity (K-Z) relation for dwarf irregular galaxies, over a large range of magnitudes, −20.5 < M K < −13.5, using a combination of K photometry from either the 2-micron all sky survey (2MASS) or the(More)
Visible spectroscopic and photometric survey of Jupiter Trojans: final results on dynamical families. Abstract We present the results of a visible spectroscopic and photometric survey of Jupiter Trojans belonging to different dynamical families. total sample of visible spectra for 80 objects. The survey allows us to investigate six families (Aneas,(More)
We perform the first statistical study of the effects of the interaction of suprathermal electrons with narrow-band whistler mode waves in the solar wind (SW). We show that this interaction does occur and that it is associated with enhanced widths of the so-called strahl component. The latter is directed along the interplanetary magnetic field away from the(More)
