Scintillation Response of 0D Cs3Cu2I5 Thin Layers to Light‐ and Heavy‐Ion Irradiation

Advanced Photonics Research, EarlyView.
Driven by increasing interest in uncovering the remarkable photoluminescence quantum yield of Cs3Cu2I5, polycrystalline thin layers are synthesized to investigate its radioluminescence response to energetic ions. Its spectroscopic capability is assessed in a wide range of ion mass and internal excitation processes are explored.

Reflection parity and space-time parity photonic conservation laws in parametric nonlinear optics

Physical Review Research
Conservation laws are some of the most generic and useful concepts in physics. In nonlinear optical parametric processes, conservation of photonic energy, momenta and parity often lead to selection rules, restricting the allowed polarization and ...

Parity Violation in Proton-Proton Scattering

, 1997
Measurements of parity-violating longitudinal analyzing powers (normalized asymmetries) in polarized proton-proton scattering provide a unique window on the interplay between the weak and strong interactions between and within hadrons. Several new proton-

No parity anomaly in massless QED3: a BPHZL approach

, 2009
In this letter we call into question the perturbatively parity breakdown at 1-loop for the massless QED_3 frequently claimed in the literature. As long as perturbative quantum field theory is concerned, whether a parity anomaly owing to radiative ...

Dose–response association between dietary patterns and gestational diabetes mellitus risk: A systematic review and meta‐analysis of observational studies

Food Science &Nutrition, Volume 11, Issue 1, Page 57-92, January 2023., 2023
To the best of our knowledge, there is no information regarding the strength and shape of a dose‐response relation between dietary patterns and risk of GDM; therefore, to provide further insights regarding the association between dietary patterns and GDM risk, we conducted a systematic review and dose‐response meta‐analysis to summarize the association
