Shaping the future of radiotherapy: the role of electron beams and flash techniques
RUDN Journal of MedicineRelevance. Radiation therapy (RT) remains a cornerstone of oncology, offering targeted treatment for various cancers. With its roots tracing back to the discovery of X-rays by Wilhelm Röntgen and radium research by Marie Curie, RT has evolved into a ...

Two-zone model for the broadband Crab nebula spectrum: microscopic interpretation
EPJ Web of Conferences, 2017 We develop a simple two-zone interpretation of the broadband baseline Crab nebula spectrum between 10−5 eV and ~ 100 TeV by using two distinct log-parabola energetic electrons distributions.

FEBS Letters, EarlyView.Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Liver organoids: modelling complexity in homeostasis and disease
FEBS Letters, EarlyView.Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Physical Review Special Topics. Accelerators and Beams, 2015 The detailed study of the low energy secondary electron yield (LE-SEY) of technical Cu for low electron energies (from 0 to 20 eV) is very important for electron cloud build up in high intensity accelerators and in many other fields of research ...

Mapping travelling convection vortex events with respect to energetic particle boundaries [PDF]
Annales Geophysicae, 1998 Thirteen events of high-latitude ionospheric travelling convection vortices during very quiet conditions were identified in the Greenland magnetometer data during 1990 and 1991.

FEBS Letters, EarlyView.This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

Secondary-electron emission from hydrogen-terminated diamond: Experiments and model
Physical Review Special Topics. Accelerators and Beams, 2011 A hydrogen-terminated diamond is a proven efficient electron emitter that can support emission of high average current. Several factors dictate the amplifier’s gain: the number of secondary electrons created at their point of entry into the diamond, the ...
