Heavily In-doped CdTe and ZnTe crystals are investigated using perturbed γγ-angular correlation experiments. By means of characteristic electric field gradients, it is shown that in the Cd (Zn) poor regime, the compensation is governed by A-center formation. After annealing in Cd (Zn) rich atmosphere, the formation of DX-centers is observed and identified as the prevailing compensation mechanis...

The in vitro postantibiotic effects (PAEs), the postantibiotic sub-MIC effects (PA-SMEs), and the sub-MIC effects (SMEs) of DX-619 were determined for 16 gram-positive organisms. DX-619 pneumococcal, staphylococcal, and enterococcal PAE ranges were 1.7 to 5.0 h, 0.7 to 1.8 h, and 1.2 to 6.5 h, respectively. The PA-SME ranges (0.4x MIC) for pneumococci, staphylococci, and enterococci were 5.2 to...

Vibrational modes are observed at ambient pressure in O-doped GaN at 544 cm using Raman spectroscopy. Investigation of these modes with applied hydrostatic pressure reveals the existence of three closely spaced modes that shift in relative intensity with increasing pressure. Notably, transitions between the different modes occur at previously observed electronic transitions associated with the ...

Vibrational modes in O-doped GaN have been observed at 544 cm~1 in Raman spectroscopy. Under perturbation of large hydrostatic pressure the mode appears as a set of three di!erent lines Q 123 whose relative intensities change by pressure. A switching between the modes occurs near 10 and 20 GPa and is found to correlate with the electron capture process to the DX-like state of O. We employ a sim...

We report on the optical storage of digital data in a semiconductor sample containing DX centers. The diffraction efficiency and the bit-error-rate performance of multiplexed data images are shown to agree well with a simple model of the material. Uniform storage without an exposure schedule is demonstrated. The volume sensitivity is found to be ~10(3) times that of LiNBO(3):Fe. The importance ...

Introduction: Breast cancer is the most common cancer and the leading cause of cancer-related death in women. Clinicopathological variables are important factors in deciding on breast cancer treatment. This study evaluated the association between the recurrence score generated by the Oncotype DX® 21-gene assay and classic clinicopathological variables. Methods: A single-institution retrospect...
