A Two‐Stage Questionnaire and Actigraphy Screening for iRBD in a Multicenter Retrospective Cohort
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Isolated rapid‐eye‐movement sleep behavior disorder is a prodromal marker of synucleinopathies. However, most cases remain undiagnosed due to the insufficient predictive value of questionnaires and limited access to confirmatory video‐polysomnography. We assessed a two‐stage screening strategy combining a brief questionnaire on rapid‐

Tree-level scattering amplitudes in nonlocal field theories
Journal of High Energy Physics, 2021 We prove in two ways that, for a special class of nonlocal field theories consistent with linear and non-linear stability at the classical level, and with unitarity and super-renormalizability or finiteness at the quantum level, the n-point tree-level ...

, 2011 Intuitively speaking, a classical field theory is back-ground-independent if the structure required to make sense of its equations is itself subject to dynamical evolution, rather than being imposed ab initio.

Quantum Gravity: Has Spacetime Quantum Properties? [PDF]
, 2009 The conceptual incompatibility between General Relativity and Quantum Mechanics is generally seen as a sufficient motivation for the development of a theory of Quantum Gravity. If - so a typical argumentation - Quantum Mechanics gives a universally valid

Benefits of Objective Collapse Models for Cosmology and Quantum Gravity [PDF]
, 2013 We display a number of advantages of objective collapse theories for the resolution of long-standing problems in cosmology and quantum gravity. In particular, we examine applications of objective reduction models to three important issues: the origin of ...

Advanced Functional Materials, Volume 36, Issue 43, 29 May 2026.In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

An étude on global vacuum energy sequester
Journal of High Energy Physics, 2017 Recently two of the authors proposed a mechanism of vacuum energy sequester as a means of protecting the observable cosmological constant from quantum radiative corrections.
