TL;DR: It is demonstrated that haloperidol treatment acts at the gene level to modulate D2 receptor content in striatal dopaminoceptive neurons, and that the D2 receptors mRNA increase in postsynaptic neurons contributes to dopamine supersensitivity induced by neuroleptics in the rat.

TL;DR: In this article, the authors measured the charged particle multiplicity distribution of hadronic Z decays using the ALEPH detector at LEP and found that the distribution has a mean 〈n〉=20.85± 0.24 and a dispersion D=6.34±0.12.

TL;DR: In this article, the forward-backward asymmetries for the channels Z → b b and Z → c c c were measured from a sample of 150 000 hadronic Z decays collected with the ALEPH detector at LEP.

TL;DR: In this paper, the polarization of τ leptons produced in the reaction e+e−→τ+τ− at the Z resonance has been measured using the τ decay modes eνeντ, μνμντ and a1ντ.

TL;DR: In this article, three signals of charm production were observed: two from the exclusive decays D ° → K − π + and D ∗+ → D °π + → K− π+ + π+, and one in the transverse-momentum distribution of soft hadrons relative to the nearest jet.

TL;DR: In this article, the authors present the French approach to Information and Communication, and sketch out some arguments pro and con for their amalgamation into a unique scientific body, and conclude that a dichotomy between information and communication is certainly not representative of the French field of Information and communication; it would rather be a continuum or a multi-polar space.

TL;DR: In this article, the authors measured the production of high energy isolated photons in hadronic Z decays with the ALEPH detector at LEP using a sample of 180 000 hadronic events.

TL;DR: In this article, events with two leptons and an additional pair of charged particles were studied and the 35 events found show a possible excess in the tau channel compared with the expectation from electroweak processes.

TL;DR: In this article, the scalar form factor of the pion was evaluated in the framework of the SU(2) Nambu-Jona-Lasinio model.

TL;DR: A search for events of the type e + e − →l + l − X 0, where X 0 can be any weakly interacting particle which couples to the Z, has been performed with the ALEPH detector at LEP, by searching for acollinear lepton pairs as discussed by the authors.
