The 520-day experimental simulation of an exploration mission provided an opportunity to apply content analysis for studying the patterns of crew--Control center (CC) communication impeded by lag times. The period of high autonomy was featured by drastic reduction of the number of crew questions and requests which was judged as a marker of adaptation to the simulated space mission environment. ...

An extremely light scalar weakly interacting with light neutrinos has interesting consequences in stellar evolution, neutrino oscillations and laboratory neutrino mass measurements. In this paper we construct realistic gauge models for such scalar-neutrino interactions.

We study decays of the neutral and charged Higgs bosons of the minimal supersymmetric standard model into a very light gravitino and a neutralino or chargino. Present experimental constraints already imply that the lighter scalar Higgs boson can only have a very small branching ratio into this mode. However, if the gravitino mass is below ∼ 0.5 eV, the heavier neutral and charged Higgs boson de...

We construct a prototype of topcolor–assisted technicolor in which, although both top and bottom quarks acquire some mass from extended technicolor, strong U(1) couplings of technifermions are isospin symmetric and all gauge anomalies vanish. There is a mechanism for mixing between the light and heavy generations and there need be no very light pseudo– Goldstone bosons.

Both behavioral and neural measures of the motivational salience of faces are positively correlated with their physical attractiveness. Whether physical characteristics other than attractiveness contribute to the motivational salience of faces is not known, however. Research with male macaques recently showed that more dominant macaques' faces hold greater motivational salience. Here we investi...

Recently, a new mechanism to generate a naturally small electroweak scale has been proposed. It exploits the coupling of the Higgs boson to an axionlike field and a long era in the early Universe where the axion unchains a dynamical screening of the Higgs mass. We present a new realization of this idea with the new feature that it leaves no sign of new physics at the electroweak scale, and up t...

In supergravity theories with a very light gravitino, the gluino decays dominantly to a gluon and a gravitino. This results in a much larger missing ET for the multijet final states in hadronic colliders. We use the latest Tevatron data for the multijet final states to set a new absolute lower bound of 3.0 × 10 GeV for the light gravitino mass.

If supersymmetry is spontaneously broken at a low energy scale then the resulting gravitino will be very light. The interaction strength of the longitudinal components of such a light gravitino to e − ẽ pair then becomes comparable to that of electroweak interactions. If such a light gravitino is present it would significantly modify the crosssection for eLe − R → ẽLẽR from its MSSM value. Prec...
