Coherent x-ray transition and diffraction radiation of microbunched beams

Physical Review Special Topics. Accelerators and Beams, 2013
Theoretical and numerical results on angular and spectral distributions and total number of photons of several types of coherent radiation produced by microbunched beams passing through radiators are presented: coherent x-ray bremsstrahlung, x-ray ...

Transition pattern and mechanism of B-lymphocyte precursors in regenerated mouse bone marrow after subtotal body irradiation. [PDF]

PLoS ONE, 2012
Little is known about the effects of ionizing radiation on the transition and the related signal transduction of progenitor B cells in the bone marrow. Thus, using an NIH Swiss mouse model, we explored the impact of ionizing radiation on the early stage ...

Transition Radiation from Rough Surfaces [PDF]

, 1990
We propose a theory of transition radiation emitted by charged particles entering a rough interface between two media. We show that the radiation process is influenced by surface inhomogeneities distributed both longitudinally and transversally with ...

Radiative transfer in ultra-relativistic outflows

, 2011
Analytical and numerical solutions are obtained for the equation of radiative transfer in ultra-relativistic opaque jets. The solution describes the initial trapping of radiation, its adiabatic cooling, and the transition to transparency.

BMP antagonist CHRDL2 enhances the cancer stem‐cell phenotype and increases chemotherapy resistance in colorectal cancer

Molecular Oncology, EarlyView.
Overexpression of CHRDL2 in colon cancer cells makes them more stem‐like and resistant to chemo‐ and radiotherapy. CHRDL2‐high cells have upregulation of the WNT pathway, genes involved in the DNA damage response (DDR) pathway and epithelial‐to‐mesenchymal transition (EMT). This leads to quicker repair of damaged DNA and more cell migration.

Quantum phase transition of infrared radiation

Journal of High Energy Physics
We describe a phase transition of infrared radiation, driven by quantum fluctuations, which takes place at the boundary of (the conformal diagram of) Minkowski spacetime.

Stochastic Thresholds: A Novel Explanation of Nonlinear Dose-Response Relationships for Stochastic Radiobiological Effects

Dose-Response, 2005
New research data for low-dose, low- linear energy transfer (LET) radiation-induced, stochastic effects (mutations and neoplastic transformations) are modeled using the recently published NEOTRANS 3 model.

Radiation hardness of indium oxide films in the Cooper-pair insulator state [PDF]

Nuclear Technology and Radiation Protection, 2012
This paper investigates possible radiation effects in the Cooper-pair insulator state of indium oxide films. Radiation effects are predicted on the basis of Monte Carlo simulations. Results of a combined theoretical and numerical analysis suggest that

Plasmonic Field-Effect Transistors (TeraFETs) for 6G Communications

Sensors, 2021
Ever increasing demands of data traffic makes the transition to 6G communications in the 300 GHz band inevitable. Short-channel field-effect transistors (FETs) have demonstrated excellent potential for detection and generation of terahertz (THz) and sub ...
