Basic personality traits and density distributions of basic personality states

26. Dani Ramira i Zorana Bujasa: međunarodni psihologijski znanstveni skup : knjiga sažetaka, Zagreb, 28. - 30. rujna 2023., 2023
Perspective on personality based on multiple assessments of momentary personality states has been gaining increased research attention. Personality states can be viewed as everyday manifestations of personality in behavior and, when assessed throughout different occasions, they form density distributions with their own parameters. The aim of this study

High deuteron and neutron yields from the interaction of a petawatt laser with a cryogenic deuterium jet

Frontiers in Physics, 2023
A compact high-flux, short-pulse neutron source would have applications from nuclear astrophysics to cancer therapy. Laser-driven neutron sources can achieve fluxes much higher than spallation and reactor neutron sources by reducing the volume and time ...
