Methods for null control and their effects on the radiation pattern [PDF]

open access: yesIEEE Transactions on Antennas and Propagation, 1986
Several methods for synthesis of array antenna patterns with prescribed nulls are reviewed. Methods based on full amplitude/phase control at each array element and methods with a restricted number of degrees of freedom are compared, with attention focused on the characteristic features of the resultant patterns.

Metabolomic Analysis Reveals Unique Biochemical Signatures Associated with Protection from Radiation Induced Lung Injury by Lack of cd47 Receptor Gene Expression

open access: yesMetabolites, 2019
The goal of this study was to interrogate biochemical profiles manifested in mouse lung tissue originating from wild type (WT) and cd47 null mice with the aim of revealing the in vivo role of CD47 in the metabolic response to ionizing radiation ...

Radiation Oncology in the 21st Century: Prospective Randomized Trials That Changed Practice… or Didn’t!

open access: yesFrontiers in Oncology, 2018
In a two-part article published in 2009, we discussed the limitations of conventional radiation therapy, the challenges of studying new technologies in radiation oncology, and summarized the state-of-the science for various malignancies (1, 2).

Resistance of bone marrow stroma to genotoxic preconditioning is determined by p53

open access: yesCell Death and Disease, 2021
Transplantation of bone marrow (BM) is made possible by the differential sensitivity of its stromal and hematopoietic components to preconditioning by radiation and/or chemotherapeutic drugs.

Quantum superradiance on static black hole space-times

open access: yesPhysics Letters B, 2020
We study the quantum analogue of the classical process of superradiance for a massless charged scalar field on a static charged black hole space-time.

Physical null zones and radiation representation [PDF]

open access: yesNuclear Physics B, 1983
Abstract General conditions for reconstructing physical null radiation zones in single photon tree amplitudes are given. The systematic analysis has been carried out using invariant quantities. For arbitrary values of masses and charges these zones are always smaller than in the massless and equal charges case. As an application the radiative W boson
