    Calculations of femtosecond differential optical transmission in germanium (1995)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 77 (1995), S. 2107-2115 
    Details
    ISSN: 1089-7550

    Thema: Physik
    Notizen: Nonequilibrium electron and hole carrier dynamics are calculated for femtosecond photoexcitation in Ge using an ensemble Monte Carlo method. From the carrier distributions and k⋅p band-structure calculations, the time-dependent differential optical transmission that corresponds to pump-probe experiments is determined. It is found that electrons quickly scatter out of the optically coupled region and that the primary electron relaxation channel is from the Γ valley to the X valleys, then to the L valleys. Holes dominate the nonlinear absorption spectra in Ge. It is also found that light holes make a substantial contribution to the initial transient of the differential transmission, particularly for high-energy photoexcitation. © 1995 American Institute of Physics.

    Dynamics in the spin-boson model by maximum entropy moment imaging (1998)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 109 (1998), S. 8262-8274 
    Details
    ISSN: 1089-7690
    Quelle: AIP Digital Archive
    Thema: Physik , Chemie und Pharmazie
    Notizen: The spin–spin time correlation function of the spin-boson model is studied using a maximum entropy imaging procedure founded on knowledge of early time derivatives or moments of the corresponding spectral density. The coherent–incoherent boundary is reproduced in agreement with the results of dynamical path-integral Monte Carlo and the procedure is shown to be stable numerically at both long time and low temperature. © 1998 American Institute of Physics.

    Genes for immunoglobulin heavy chain and serum prealbumin protein are linked in mouse (1975)
    [s.l.] : Nature Publishing Group
    Nature 256 (1975), S. 644-646 
    Details
    ISSN: 1476-4687
    Quelle: Nature Archives 1869 - 2009
    Thema: Biologie , Chemie und Pharmazie , Medizin , Allgemeine Naturwissenschaft , Physik
    Notizen: [Auszug] The autosomal prealbumin locus (Pre) determines the per-sence or absence of a minor serum protein band that migrates ahead of the albumin band on electrophoresis14. Density of the band is hormone dependent, and is greatest in sexually mature males. The Prea allele determines the presence of the ...

    A simple Bragg-spacing comparator (1978)
    [S.l.] : International Union of Crystallography (IUCr)
    Acta crystallographica 34 (1978), S. 484-489 
    Details
    ISSN: 1600-5724
    Quelle: Crystallography Journals Online : IUCR Backfile Archive 1948-2001
    Thema: Chemie und Pharmazie , Geologie und Paläontologie , Physik
    Notizen: A simple Bragg-spacing comparator is described which achieves a routine precision of 3 parts in 108 in lattice-spacing measurements. One conventional X-ray source and three detectors are required and measurements take only 10 min. The instrument is used to survey the lattice-parameter variations in silicon crystals manufactured by many different suppliers since 1965.

    Notes on Seneca's Quaestiones Naturales (1979)
    Cambridge : Cambridge University Press
    The @classical quarterly 29 (1979), S. 448-456

    ISSN: 0009-8388
    Quelle: Cambridge Journals Digital Archives
    Thema: Klassische Philologie, Byzantinistik, Mittellateinische und Neugriechische Philologie, Neulatein
    Notizen: ‘In spite of the efforts of scholars to improve matters, the condition of Seneca's text remains in many places most uncertain or quite irrecoverable. Again and again one has to be content with conjectures which, while often giving the general sense of a passage, must not be taken as certainly Seneca's words’ (Corcoran).1. praef. 5 o quam contempta res est homo, nisi supra humana surrexerit! quam diu cum affectibus colluctamur, quid magnifici facimus, etiam si superiores sumus? portenta vincimus: quid est cur suspiciamus nosmet ipsos, quia dissimiles deterrimis sumus? Traditional punctuation: ‘... quid magnifici facimus? etiam si superiores sumus, portenta vincimus’

    Comparison of areal and estimated volumetric bone mineral density values between older men and women (1995)
    Springer
    Osteoporosis international 5 (1995), S. 271-275 
    Details
    ISSN: 1433-2965
    Schlagwort(e): Bone densitometry ; Bone mineral density ; Dual-energy X-ray absorptiometry ; Gender differences ; Osteoporosis
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Abstract We compared areal bone mineral density (BMD) of the total body (TBMD), antero-posterior lumbar spine at L3 (APS), lateral spine at L3 (LS) and femoral neck (FN). In order to understand better the effect of gender-related size differences on BMD, we also compared the estimated volumetric BMD at L3 (VLS) and the femoral neck (VFN). Subjects were asymptomatic women (n=22) and men (n=44) with an age range of 58–79 years. BMD at each site was measured by dual-energy X-ray absorptiometry using a Hologic 2000 in array mode. Results of the statistical analyses (ANOVA) showed the men to have significantly greater BMD at all areal sites [APS, LS (p〈0.05); FN (p〈0.01); TBMD (p〈0.001)]. The two estimated volumetric comparisons, however, showed no gender differences. Results demonstrate how measures from areal BMD measures can be misleading when comparing groups of different size. In older men and women planar measures may overestimate gender differences in BMD.

    Prophylactic gastropexy in the asplenia syndrome (1996)
    Springer
    Pediatric surgery international 12 (1996), S. 28-29 
    Details
    ISSN: 1437-9813
    Schlagwort(e): Key words Prophylactic gastropexy ; Asplenia ; Ivemark syndrome ; Gastric volvulus
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Abstract  The asplenia [Ivemark] syndrome (AS) is the association of congenital absence of the spleen with a variety of visceral abnormalities, predominantly of the cardiovascular system. Varying degrees of malrotation and malfixation of the bowel are common in this condition, and the occurrence of catastrophic gastric volvulus due to malfixation of the bowel has been reported. With the improvement in long-term outlook for these patients with modern cardiac surgery and prophylactic antibiotics, the intra-abdominal anomalies have become increasingly significant. This paper draws attention to the prophylactic treatment of gastric malfixation in the AS through the presentation of two cases in which gastropexy was performed.
