An investigation of the emittance of escaping fast electron beams from planar and nanowire targets

High Power Laser Science and Engineering
Fast electron generation and transport in high-intensity laser–solid interactions induces X-ray emission and drives ion acceleration. Effective production of these sources hinges on an efficient laser absorption into the fast electron population and ...

Ductal Carcinoma In Situ: To Irradiate or Not to Irradiate? [PDF]

Journal of Oncology Practice, 2016
Ductal carcinoma in situ (DCIS) is a heterogeneous entity that has continued to perplex clinicians and patients despite extensive efforts to characterize its behavior andbesttreatmentstrategies.Asastand-alone diagnosis, it poses no mortality risk, yet the local therapyoptions range frommastectomy to limited excision, with or without radiation therapy ...

The Lattice Structure and Optical Properties of Neodymium-Doped Gadolinium Vanadate Crystals Induced by Ion Irradiation

IEEE Photonics Journal, 2017
In recent times, the neodymium-doped gadolinium vanadate (Nd:GdVO4) crystal has attracted significant attention as one of the most valuable functional materials, but its lattice structure can be easily modified in an irradiation environment, which ...

Radiation mutagenesis of Bacillus velezensis and its antibacterial effect on Colletotrichum gloeosporioides

Fushe yanjiu yu fushe gongyi xuebao, 2023
We used 60Co-γ ray and electron beam irradiation to mutate Bacillus velezensis to breed genetically stable mutant strains. The mutant strains were screened and re-screened by plate confrontation and the four-point method to study their antibacterial ...

The cos 2ϕ azimuthal asymmetry in ρ 0 meson production in ultraperipheral heavy ion collisions

Journal of High Energy Physics, 2020
We present a detailed study of vector meson photoproduction in ultraperipheral heavy ion collisions (UPCs). Using the dipole model, we develop a framework for the joint impact parameter and transverse momentum dependent cross sections.

Theory of a quodon gas. With application to precipitation kinetics in solids under irradiation

, 2014
Rate theory of the radiation-induced precipitation in solids is modified with account of non-equilibrium fluctuations driven by the gas of lattice solitons (a.k.a. quodons) produced by irradiation.

Social context prevents heat hormetic effects against mutagens during fish development

FEBS Letters, EarlyView.
This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...
