    Study of Acoustoelectrically Amplified Phonons in InSb by Anomalous Transmission of X-Rays

    Anomalous transmission of x-rays is a channelling phenomenon of photons in crystals. A convenient geometry for realizing anomalous transmission consists of using a crystal plate with the lattice diffracting pl...

    Acute changes in blood-CSF barrier permselectivity to serum proteins after intrathecal methotrexate and CNS irradiation

    Ten children affected by acute lymphoblastic leukaemia without CNS involvement were treated with a CNS prophylaxis protocol. Intrathecal methotrexate and CNS irradiation (60Co) administered at different times bot...

    Solution of phase problem for crystallography at a wavelength of 3.5 Å

    It has been established1 that one viable method for determining phases in a diffraction experiment is to make use of multiple beam-diffraction, that is, a situation in which two or more reflections are excited s...

    Multiple Bragg Scattering and the Phase Problem in X-Ray Diffraction: Perfect Crystals

    A crystal set in such a way as to excite a Bragg diffraction from the (hkl) planes, may under certain circumstances be oriented so that another set of planes (HKL) forms the correct Bragg angle with the incident ...

    Multiple Bragg Scattering and the Phase Problem in X-Ray Diffraction: Mosaic Crystals

    The scattering of electromagnetic radiation from a finite object can be treated with complete generality by making use of Maxwell equations (Jackson, 1975). In this section we will describe a perturbation theo...

    X-Ray and Neutron Interferometry: Basic Principles and Applications

    Interferometry is based on the idea of creating spatially separated coherent beams, which can be brought together and produce interference effects. Optical interferometry is a well established field. Coherent ...

    A useful ultrasound score to select thyroid nodules requiring fine needle aspiration in an iodine-deficient area

    Background: The high prevalence of thyroid nodules in iodine-deficient areas is a practical problem because of the large number of patients requiring fine needle aspiration (FNA) to detec...

    Optimization of patient selection for EGFR-TKIs in advanced non-small cell lung cancer by combined analysis of KRAS, PIK3CA, MET, and non-sensitizing EGFR mutations

    We present a comprehensive analysis of KRAS, PIK3CA, MET, and non-sensitizing EGFR mutations in advanced non-small cell lung cancer (NSCLC) patients treated with tyrosine kinase inhibitors (TKIs), with the aim of...
