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

Frontiers 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).

Quantum superradiance on static black hole space-times

Physics 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.

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

Cell 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 focusing conjecture and the Page curve

Journal of High Energy Physics, 2023
The focusing theorem fails for evaporating black holes because the null energy condition is violated by quantum effects. The quantum focusing conjecture is proposed so that it is satisfied even if the null energy condition is violated.

Novel Multi-Band SIW Antenna with Filtering Function [PDF]

Journal of Electromagnetic Engineering and Science
In this paper, the basic structure of a quad-band substrate-integrated waveguide (SIW) antenna with filtering characteristics is proposed. The proposed antenna consists of a four-slot SIW and a single-probe feed. Despite having a single feed, it was able

Physical null zones and radiation representation [PDF]

Nuclear 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

Failure Correction of a Linear Array of Coupled Parallel Vertical Dipole Antennas

Journal of Telecommunications and Information Technology, 2020
In this paper, a cuckoo search algorithm based on the combined characteristics of the brood parasite behavior and Levy flights is applied to correct the radiation pattern of a linear antenna array composed of parallel dipoles with faulty elements.

Synchrotron X-Ray Radiation-Induced Bystander Effect: An Impact of the Scattered Radiation, Distance From the Irradiated Site and p53 Cell Status

Frontiers in Oncology, 2021
Synchrotron radiation, especially microbeam radiotherapy (MRT), has a great potential to improve cancer radiotherapy, but non-targeted effects of synchrotron radiation have not yet been sufficiently explored.

A Dual-Band Patch Antenna with Combined Self-Decoupling and Filtering Properties and Its Application in Dual/Squad-Band Two-Element MIMO Array

Sensors
This paper proposes a dual-band patch antenna with combined self-decoupling and filtering properties, designed to suppress mutual coupling between two antenna elements both within the same dual-band and across different dual-bands. Initially, a dual-band
