    Si in-diffusion during the 3D islanding of Ge/Si(001) at high temperatures (1999)

    Notes: Abstract. The 3D islands of the Stranski–Krastanow system Ge/Si(001) that form either during the annealing of previously flat and nearly strain-relieved Ge films at 1020 K or directly at the Ge deposition at 1020 K are found to be composed of a mixture of Ge and Si, thus pointing to considerable interdiffusion at 1020 K. Direct measurement of the elastic energy unambiguously reveals that neither the 3D islanding nor the Si in-diffusion are driven by the reduction of misfit strain; this strain being the result of increasing configurational entropy.

    In vivo induction of HLA molecules in patients with myeloproliferative syndrome during IFNα treatment (1991)

    Notes: Summary Eighteen patients with myeloproliferative syndrome (14 with chronic myeloid leukemia, four with essential thrombocytosis) were investigated for modulation of HLA antigens on peripheral blood lymphocytes, monocytes, and hematopoietic precursors during IFNα therapy as a sign of potentially increased immune recognition of malignant cells. After 1 month of IFNα therapy, an increased number of monocytes and hematopoietic precursor cells, but not of lymphocytes, expressed HLADQ antigens. In addition, a strong induction of HLA class-I antigens was found on both hematopoietic progenitors and normal peripheral blood mononuclear cells. With daily injections of IFN in the first month of therapy stimulation continuously increased, suggested a major effect of IFNa on hematopoietic progenitors with sustained enhanced expression of HLA class-I antigens during differentiation of myelomonocytic cells. HLA class-I antigen expression was consistently augmented by IFNα in all patients, irrespective of their hematological response.
