    Theory of the generation and detection of carriers in ultrafast pump-and-probe spectroscopy of semiconductors (1996)

    Notes: We present an analysis of several of the factors that contribute to experimentally measured pump-probe spectra. We point out that for a correct description of the carrier generation, a full quantum mechanical description is essential. In addition, we discuss the regimes where the quantum mechanical description based on the Bloch equations can be replaced by a simplified semiclassical approach. We also demonstrate that the detection of nonequilibrium carrier distributions with the probe pulse is a nontrivial process due to quantum effects, and derive expressions for the detected signal for different experimental schemes. © 1996 American Institute of Physics.

    Calculations of femtosecond differential optical transmission in germanium (1995)

    Notes: 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.

    Dietary Influences on Bovine Milk cis-9,trans-11-Conjugated Linoleic Acid Content (1997)

    Notes: The effects of grass dry matter (DM) allowance and dietary supplements of full fat rapeseeds on levels of cis-9,trans-11 octadecadienoic (CLA) acid in bovine milk were investigated. Grass allowance of 16 kg/(cow*day) resulted in reduced (p〈0.05) milk fat CLA levels (3.91 mg CLA/g fat) compared to 20 kg/(cow*day) after 19 wk treatment. CLA levels increased in milk fat from cows on a high-rapeseed-supplemented diet (p〈0.001) (1650 g/(cow*day) full fat rapeseed) compared to the control (pasture) and low rapeseed (p〈0.01) (825 g/(cow*day) full fat rapeseed) supplemented diets. The variation in milk fat CLA levels among individual cows over both trials was 1.5–16 mg/g.

    Lipid and Cholesterol Oxidation in Whole Milk Powder during Processing and Storage (1997)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: The influence of animal feed quality on lipid and cholesterol oxidation in whole milk powder was investigated. Powders from a herd receiving a ‘supplemented’ diet showed reduced PV (p 〈 0.01) and TBARS (p 〈 0.09) compared to a ‘restricted’ herd, after storage in both vacuum and sachet-packs and less (p 〈 0.003) cholesterol oxidation products (COPs). High pre-heating temperatures resulted in higher levels of PV, TBARS and COPs in fresh whole milk powders than low pre-heat temperatures, but after storage the reverse occurred. Superior animal feed quality and proper control of processing and storage conditions enhanced oxidative stability of whole milk powder. Lipid and cholesterol oxidation were positively correlated (p 〈 0.001).

    Notes: Abstract Langerhans cell histiocytosis is a systemic disorder consisting of abnormal histiocyte proliferation, in the form of focal deposits. Central nervous system involvement is most common in the hypothalamus, although other sites have been described, such as the cerebellum and the meninges. We present a case with presumed involvement of the corpus callosum and cerebellum, demonstrating gadolinium enhancement on MRI.

    Interwell excitons in GaAs multiple quantum wells and superlattices (1995)

    Notes: Summary The optical properties of multiple quantum wells in the transition from isolated wells to a superlattice are investigated theoretically and experimentally. For superlattices with a miniband width similar to the binding energy of the 2s exciton of the isolated quantum well we find an exciton state energetically between the 1s exciton state and the onset of the miniband absorption. We find this state to be an interwell exciton, with the electron confined to one well and the hole to the neighboring well. The interwell exciton resembles the first Wannier-Stark localized exciton of a biased superlattice. However, the localization in the present case is mediated by the Coulomb interaction of the electron and hole. The state has considerable oscillator strength and is observed experimentally in linear and nonlinear experiments.

    Laparoscopic splenectomy for idiopathic thrombocytopenic purpura (ITP) (1999)

    Notes: Abstract Background: Laparoscopic splenectomy (LS) has rapidly become the preferred surgical treatment for idiopathic thrombocytopenic purpura (ITP), but its long-term efficacy for this disorder is unproved. This report documents the author's 5-year experience with, and long-term follow-up of, LS for ITP. Methods: Between September 1992 and September 1997, 30 patients with clinical ITP and intractable thrombocytopenia were referred as surgical candidates. Two of them (7%) were converted to open, and the other 28 underwent successful LS. The operative approach evolved from a supine lithotomy to right lateral decubitus position, and the harmonic scalpel became the primary dissection tool in the later part of the study. Results: The 28 successful LS patients constituted the study group. Accessory spleens were identified and resected in six patients (21%). Surgical times and blood loss averaged 2.4 h and 170 cc, respectively. The typical hospital stay was 2 days. Initial reversal of thrombocytopenia and ultimate cessation of oral steroids was achieved in 25 of 28 patients (89%). There were no deaths, but two patients had major complications (bleeding and pneumonia). All but two patients experienced a return to full activity and/or employment by 3 weeks post-LS. In the three cases that failed LS, none had residual splenic tissue on subsequent radionuclide scan. Long-term follow-up (2–60 months) was obtained in 22 of 28 patients (79%). The only death (at 13 months) resulted from oncologic disease. Twenty-one patients had lasting clinical remission of ITP. A positive preoperative response to oral steroids was the best predictor of success. Conclusions: This 5-year experience with LS supports its use for the surgical treatment of ITP. The procedure is safe and efficacious, resulting in brief hospitalization, minimal recovery time, and excellent long-term results.

    True Colors: The Response of Business Schools to Declining Enrollments (1997)

    Notes: Abstract During the last several decades, business schools have increasingly portrayed themselves as the advocates and teachers of business ethics. In this context, educators have examined, criticized, and written about the questionable actions of many organizations. Business schools are, however, currently facing their own unprecedented crisis in the form of dramatically declining enrollments. This paper examines the morality of the various possible response strategies and argues that how business schools respond to this crisis will serve as a clear indication of their own organizational ethics and values.
