PHYSICAL AND BIOLOGICAL OBSERVATIONS ON HERPESVIRUS [PDF]
Journal of Bacteriology, 1963 Smith, KendallO. (Baylor University College of Medicine, Houston, Texas). Physical and biological observations on herpesvirus. J. Bacteriol.86:999–1009. 1963.—The development of herpesvirus in human lung fibroblasts was studied by plaque assays and physical particle counts. Approximately 200 infectious units and 60,000 particles were produced by single

Observers, observations and referencing in physics theories
Journal of Physics: Conference Series, 2021 Abstract Is it possible to encompass the full extent of the universe within a theory based on a finite set of first principles and inference rules? The r^ole of observers and observations in physics theories is considered here in the light of G¨odel’s incompleteness theorem.

Active Disturbance Rejection Control for the Robust Flight of a Passively Tilted Hexarotor
Drones, 2022 This paper presents a robust control strategy for controlling the flight of an unmanned aerial vehicle (UAV) with a passively (fixed) tilted hexarotor. The proposed controller is based on a robust extended-state observer to estimate and reject internal ...

Gravitational entropy is observer-dependent [PDF]
Journal of High Energy PhysicsIn quantum gravity, it has been argued that a proper accounting of the role played by an observer promotes the von Neumann algebra of observables in a given spacetime subregion from Type III to Type II.

Crossed products and quantum reference frames: on the observer-dependence of gravitational entropy [PDF]
Journal of High Energy PhysicsA significant step towards a rigorous understanding of perturbative gravitational entropy was recently achieved by a series of works showing that a proper accounting of gauge invariance and observer degrees of freedom converts the Type III algebra of QFT

The problem of connection of observer’s mind with quantum-mechanical description of physical reality
Вестник Мининского университета, 2019 Introduction: the study considers the problem of observer’s status during specific quantum-mechanical experiments, in which the empirical result directly depends on the participation of the experimenter's mind.

What makes you an observer? [PDF]
Journal of Physics, Conference SeriesBoth empirical and theoretical objective science can only access relations, revealing nothing about the intrinsic nature of the entities “in relation”.

Synergies of THESEUS with the large facilities of the 2030s and guest observer opportunities [PDF]
Experimental astronomy (Print), 2021 The proposed THESEUS mission will vastly expand the capabilities to monitor the high-energy sky. It will specifically exploit large samples of gamma-ray bursts to probe the early universe back to the first generation of stars, and to advance multi ...
