    Notes: Abstract  To test the hypothesis of a planning dysfunction in schizophrenia using a precise temporal definition, the readiness potential (RP), a negative cortical wave preceding self-initiated movements and reflecting motor preparation processes, was studied in patients under stable medication and in controls. The supplementary motor area (SMA), known to be involved in the generation of the RP, has also been implicated in movement selection (fixed versus free) and complexity (single versus sequence). This is the first study using RP for the assessment of the influence of these factors on motor preparation in schizophrenics. Our results show that schizophrenics’ RP amplitude is significantly lower than in controls at central and contralateral electrodes. However, RP amplitude increases with task difficulty in both groups, offering important new insight into classical SMA hypoactivation in schizophrenics performing motor tasks. Topographic analysis shows that RP amplitude is, for both groups, significantly higher in sequence than in single movements at fronto-central sites and higher for free than for fixed movements at centro-parietal sites. Finally, RP onset occurs significantly later in schizophrenics than in controls. These results support the view of a motor-preparation and decision-making dysfunction in schizophrenia. They are interpreted within the framework of a fronto-striatal disorder in this disease.

    Notes: Abstract We carried out four separate studies using random amplified polymorphic DNA (RAPD) markers to analyse samples of Eucalyptus supplied by several different organisations. The objective was to examine the reproducibility of the RAPD technique and its ability to discriminate between individual genotypes for verification of clonal identities. We found that RAPD profiles that are unique to a genotype can be generated reliably and simply and that even closely related genotypes can be distinguished. In addition, in each of the four studies, we detected cases where the plant material studied had been mis-sampled or mis-labelled (i.e. the RAPD profiles were not consistent with the identification numbers): (1) ramets of a Eucalyptus grandis clone were found to be derived from 2 different clones; (2) ramets labelled as 2 different Eucalyptus hybrid clones were found to be the same clone, owing to a mis-planted clonal hedge; (3) samples supplied as a single progeny of a controlled E. nitens cross were derived from two crosses involving different pairs of parents; (4) mis-labelling was detected for ramets of 4 of a set of 10 clones of E. grandis and E. camaldulensis. For three of the four studies, the detection of genotype mis-identifications was unexpected, suggesting that labelling or sampling errors during the handling of plant material are a frequent occurrence, with potentially serious economic consequences.

    Notes: Zusammenfassung Die bisherigen Untersuchungen über Wachstum der Moose in Dunkelkulturen ergaben, daß die Moose ohne Lichtzutritt nur Protonema zu bilden fähig sind. Neue Versuche, über die berichtet wird, mit der Kultur der Moose,Splachnum sphaericum L. fil.,Splachnum ampullaceum L. undTrematodon ambiguus Hornsch, hatten ein entgegengesetztes Resultat. Die genannten Moose bildeten in Dunkelkulturen auf festem Agarnährboden wie auch in flüssigem Medium mit Saccharosezusatz Gametophyten. Die unter diesen Bedingungen gebildeten Gametophyten waren chlorophyllfrei und die Phylloide waren schuppenförmig. Aus diesen und anderen jetzt durchgeführten Versuchen ist zu schliessen, daß nicht das Licht, sondern die Nährstoffart und der Nährstoffvorrat für die Gametophytenentstehung bestimmend ist.

    Notes: Abstract: The process of dissociative attachment (DA) of low-energy electrons ) to vibrationally excited sodium dimer molecules is studied with high electron energy resolution ( ) in a supersonic molecular beam. A novel photoelectron source, based on two-step photoionization of the sodium atoms in the beam, may deliver a current of up to 1 nA and has been used with a current of typically 0.2 nA in this experiment. The energy dependence of the rate of sodium anion formation is determined by ion detection based on a time-of-flight analysis. The molecules are selectively excited to levels using the technique of coherent population transfer by delayed pulses (STIRAP). The comparison of the experimental data with recent resonance model calculations based on improved potential curves reveals generally good agreement for levels v ”〉12. For some distinct differences between theoretical and experimental results persist.

    Notes: Abstract: We have studied the formation of ions in collisions of Na(3 d ,5 s ,4 d ) atoms with vibrationally excited Na 2 ( v ”) molecules in their electronic ground state in a supersonic beam. The cross-section of the Na associative ionization is found to be about six times larger than that of the corresponding atomic reaction Na . Associative ionization in collisions of Na(3 d ) with Na 2 ( v ”) is observed only with vibrationally excited Na2 molecules. The cross-section of this reaction increases only slightly with v ” for low vibrational excitation, while a strong increase with v ” is observed for . The latter observation suggests the opening of the channel leading to the formation of ions in the first electronically excited state for .

    Notes: Based on resonant two-photon ionization of 21Li3 with cw lasers and mass-selective detection of 21Li3+ ions by a quadrupole mass spectrometer, isotope-selective rotationally resolved spectra of vibronic bands in the electronic A 2E″←X 2E′ system have been recorded. The complex but completely resolved spectra could be analyzed using optical–optical double resonance techniques in combination with accurate ab initio calculations which provide potential energy surfaces and rovibronic term values for both electronic states. A detailed comparison between experimental and theoretical results for the (vs′=0, vb′=0, va′=0)←(vs″=0, vb″=0, va″=0) band demonstrates excellent agreement. The coupling between pseudorotation and rotational motion is shown to produce complex level patterns which, however, can be accurately represented by an effective pseudo/rotation Hamiltonian in terms of rotational and coupling constants that directly provide structural information. For both electronic states the nuclear dynamics is adequately described as a motion on a single adiabatic potential surface with a geometric phase π for closed loops around the conical intersection at D3h geometries. © 2000 American Institute of Physics.
