We analyze the infrared behavior of the two and four-point functions for the massless O(N) model in Lorentzian de Sitter spacetime, using the 1/N expansion. Our approach is based in the study of the Schwinger-Dyson equat...

Background Cognitive–behavioural theories of panic disorder posit that panic attacks arise from a positive feedback loop between arousal-related bodily sensations and perceived threat. In a recently developed computati...

Abstract Computer models and simulations have provided enormous benefits to researchers in the natural and social sciences, as well as many areas of philosophy. However, to date, there has been little attempt to use comp...

Universities increasingly implement online delivery to strengthen students’ access and flexibility. However, they often do so with limited understanding of the impact of online pedagogy on student engagement. To explor...

Relativity theory severely restricts the ability to perform nonlocal measurements in quantum mechanics. Studying such nonlocal schemes may thus reveal insights regarding the relations between these two fundamental theori...

The paper analyses various scientific approaches to the interpretation of the essence of the concept of “personnel management”, defines the specific characteristics and principles of this process. For a detailed stud...
