Scalar Radiation from Chameleon-Shielded Regions

Physical Review Letters, 2011
I study the profile of the Chameleon field around a radially pulsating mass. Focusing on the case in which the background (static) Chameleon profile exhibits a thin-shell, I add small perturbations to the source in the form of time-dependent radial pulsations.

Deciphering the Role of Cancer Stem Cells in Breast Cancer Brain Colonization Using a Novel Patient‐Derived Model

Advanced Healthcare Materials, EarlyView.
This study shows that stem‐like cells isolated from breast cancer brain metastases drive the spread and growth of tumors in the brain. Among them, a highly adhesive subgroup initiates metastasis and resists many drugs. By closely reflecting patient tumors, these models help identify new targets and improve the development of effective treatments ...

Radiation Dominated Electromagnetic Shield

, 2017
We analyze the collision of a high energy electron beam with an oscillating electric and magnetic field configuration, which represents a three-dimensional standing electromagnetic wave. The radiating electrons are stopped at the distance of the order of or less than the electromagnetic wave wavelength, and become trapped near the electric field local ...
