    Notes: The aim of the study is to identify factors influencing infants’ crying behaviour (total crying duration, length of crying bouts, and frequency of crying). The searching for variables explaining inter-individual differences requires a sufficient stability of the cry parameters at least over short time intervals. Thus, a second aim is to assess the intra-individual stability of the crying behaviour in an age range from 3 to 12 months. Sixty-two mother–child dyads participated in the study. The results show substantial stabilities of the crying behaviour of infants between 3 and 12 months of age. This is related to the amount of crying as well as to the pattern of crying shown by the children over a 24 h interval. The typical cry pattern is characterized by peaks at 12.00 h and early in the evening, although there are large individual differences between the children with regard to cry durations at each hour of the day. Regarding the cry durations at 3 months of age, birth complications and the perceived emotional atmosphere in the mothers’ family of origin are the major contributing factors.

    Notes: An extremely sensitive miniature torque magnetometer using Si p-doped piezoresistive cantilevers is described. The magnetization m↘ of very small magnetic or superconducting samples (≤1 μg) deposited on the cantilever can be measured via the torque τ↘=m↘×B↘ produced on them by an applied field B. The high resolution in the lever deflection of the order of 0.1 A(ring) corresponds to a torque sensitivity of the order of Δτ(approximately-equal-to)10−14 Nm. In a homogeneous field of 1 T this device allows magnetic moments as small as Δm(approximately-equal-to)10−14 Am2 to be measured, a value far smaller than that measurable by the best commercial superconducting quantum interference device magnetometers. Measurements performed on microcrystals of the high-Tc superconductors Bi2Sr2Ca1Cu2O8 and Hg1Ba2Ca3Cu4O10 in the static and dynamic modes demonstrate the excellent performance of this device at low temperature and in magnetic fields ranging between a few mT and 5 T. © 1996 American Institute of Physics.

    Notes: The vibrational level structure and unimolecular dissociation dynamics of highly vibrationally excited X˜ 2A DCO were investigated using the method of stimulated emission pumping spectroscopy (SEP). Single vibration-rotation states were probed with excitation energies up to E(X˜)=18 200 cm−1, (approximate)12 700 cm−1 above the asymptotic D-CO dissociation limit. The vibrational level structure of the molecule was found to be determined by distinctive polyads arising from a 1:1:2 resonance between the CD stretching, CO stretching, and DCO bending vibrations. Anharmonic coupling mechanisms give rise to considerable level mixings, especially regarding the CD and CO stretching motion. Thus, only a minority of vibrational states can be unambiguously assigned. The spectral line shape profiles of (approximate)100 highly excited "resonance states" in the continuum above the D-CO dissociation limit were measured at high resolution. The profiles are homogeneously broadened. The unimolecular decay rates, obtained from the observed line widths, were observed to fluctuate by more than two orders of magnitude in a strikingly state specific manner. The decay rates on average increase with increasing vibrational excitation energy. The state resolved experimental data are compared to predictions of the microcanonical specific unimolecular rate coefficients calculated from different statistical models. Serious problems were encountered considering the calculation of the density of states of the molecules in the continuum region of the potential energy surface regarding the contribution of the disappearing oscillator. Despite tentative corrections, the calculated rate coefficients were to too high by one to two orders of magnitude. Overall, the unimolecular dynamics of DCO appears to conform to an intermediate case between the strictly vibrationally "mode specific" and the "statistical" limits. © 1997 American Institute of Physics.

    Notes: [Auszug] In 1983, Hock et al6 studied Jahn-Teller (JT) ions in a conductor within a linear chain model. They showed that a small JT polaron (the combination of the electron and induced lattice distortion around it) can be formed when the JT stabilization energy is comparable with the bare conduction ...

    Notes: [Auszug] Recently there has been increasing evidence that polaronic charge carriers are present in the normal state of the layered copper oxides4'5. However, it is not clear whether these normal-state polaronic carriers condense into Cooper pairs. To show that this occurs, it is necessary to demonstrate ...

    Notes: Abstract. Nuclear interaction and charge-changing cross sections were measured for 950 ⋅A MeV 20N, 20O, 20F, 20Ne, 20Na and 20Mg beams incident on a carbon target. The experimental results are compared to other data, in particular to those obtained for stable nuclei. Root mean square nuclear matter radii and upper limits of root mean square proton radii are derived from the experimental data. Evidence is presented for the existence of a neutron skin in 20N.

    Notes: Abstract Using an 11.4MeV/u136Xe beam of the UNILAC accelerator of GSI and anatW target, A=184 isobars were produced and separated by using an on-line mass separator. A new isomeric state was found in184Hf. This state decays with a half-life of 48(10) s and emits three γ-rays of 73, 482, and 555 keV as well as lower-lying cascade transitions. The hindrance of the 73 keV-E1 transition with ΔK=8 is compared with those of other even-even hafnium isotopes. The half-life of184Lu was estimated to be between 15 and 25s.

    Notes: Abstract: Anisotropic Ginzburg-Landau superconductors of extreme type-II are considered in an approximation where magnetic field fluctuations are neglected. A formulation of the scaling properties is presented for the singular part of the free energy density in the presence of a magnetic field. From the existence of a magnetization, a diamagnetic susceptibility and superconductivity we determine the limiting behavior of the scaling function in the vicinity of the zero field transition temperature, where critical fluctuations dominate. Our predictions for the temperature and field dependence of magnetization, magnetic torque and melting line etc., uncover the universal critical properties and provide an extension of hitherto used mean-field treatments. The results are consistent with experimental data.

    Description / Table of Contents: Zusammenfassung 60 Patienten mit einer ausgeprägten Penisdeviation [40 aufgrund einer kongenitalen Penisdeviation (CPD) und 20 als Folge einer Induratio Penis Plastica (IPP)] wurden in einer retrospektiven Studie mit einem durchschnittlichen Follow-up von 45 Monaten mittels Fragebogen zum Operationsergebnis befragt. Bei 49 dieser 60 Patienten wurde nach Nesbit, bei 11 Patienten nach der modifizierten Technik von Schroeder und Essed verfahren. Insgesamt kam es bei 15 Patienten (25 %) zu einem Rezidiv. Obwohl bei der Operation nach Schroeder und Essed durchgängig nicht-resorbierbares Nahtmaterial verwendet wurde, lag die Rezidivquote in dieser Gruppe deutlich höher als in der Nesbit-Gruppe (55 bzw. 18 %). Dies ist unserer Ansicht nach durch die zu geringe Zugfestigkeit reiner Raffnähte bedingt. IPP-Patienten wiesen unabhängig vom Operationsverfahren eine höhere Rezidivrate auf als die Patienten mit einer CPD (35 % gegenüber 20 %). Ursache hierfür dürfte der nie sicher auszuschließende Progreß der Erkrankung sein; 71 % der nach Nesbit operierten Patienten waren mit dem erzielten Ergebnis zufrieden, in der Gruppe der nach Schroeder und Essed operierten Patienten waren dies lediglich 36 %. Unabhängig vom Operationsverfahren beklagten IPP-Patienten postoperativ häufiger Spätkomplikationen und Erektionsstörungen, sie äußerten sich seltener mit dem erzielten Ergebnis zufrieden als Patienten mit einer CPD (50 % gegenüber 73 %). Wir führen dies darauf zurück, daß Patienten mit einer CPD und einer IPP hinsichtlich Altersstruktur und Morbidität sehr unterschiedliche Kollektive darstellen, IPP-Patienten weisen häufig bereits präoperativ Erektionsprobleme auf. Insbesondere bei IPP-Patienten ist präoperativ eine erektile Dysfunktion auszuschließen, bei ihrem Vorliegen sind andere Therapiekonzepte zu bevorzugen.
    Notes: Summary 60 patients with a marked penile deviation [40 because of a congenital penile deviation (CPD) and 20 as a result of the Peyronie's disease] were questioned about the result of the operation by means of a questionnaire in a retrospective study with an average follow-up of 45 month. The Nesbit procedure had been used with 49 of these 60 patients, the modified Schroeder-Essed technique had been used with 11 patients. There were 15 patients (25 %) in all, who suffered a relapse. In spite of the continual use of non-absorbable suture material with the Schroeder-Essed technique, the number of relapses was in this group plainly higher than in the Nesbit group (55 % and 18 % respectively). In our opinion this is caused by the insufficient tensile strength of pure plications. Regardless of the operating method, patients suffering from IPP showed a higher number of relapses than patients having a CPD (35 % and 20 % respectively). The reason for this might be the fact that one can never rule out completely the possibiliy of a further progress of the disease. 71 % of the patients in the Nesbit group were satisfied with the results of the operation, in the Schroeder-Essed group there were only 36 %. Irrespective of the operating method, IPP patients complained moreoften about late complications and erection problems after the operation and were more rarely satisfied with the result than patients with a CPD (50 % and 73 % respectively). We put this down to the fact that patients with a CPD and patients suffering from IPP represent very different collectives as far as age structure and morbidity are concerned. IPP patients frequently have erection problems even before the operation. Especially with IPP patients, preoperative erectile disfunction must be excluded, in the case of their occurrence there are to prefer other programmes of therapy.
