An on-line library of afterglow light curves [PDF]

open access: yes, 2011
Numerical studies of gamma-ray burst afterglow jets reveal significant qualitative differences with simplified analytical models. We present an on-line library of synthetic afterglow light curves and broadband spectra for use in interpreting ...

PHYSICAL AND BIOLOGICAL OBSERVATIONS ON HERPESVIRUS [PDF]

open access: yesJournal 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

Interpreting Observations of Physical Systems [PDF]

open access: yesIEEE Transactions on Systems, Man, and Cybernetics, 1987
An unsolved problem in creating diagnostic expert systems is generating a qualitative understanding of how the system is behaving from raw data, especially numerical data taken across time. Yet automating this critical step is necessary for building the next generation of expert systems.

The problem of connection of observer’s mind with quantum-mechanical description of physical reality

open access: yesВестник 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.

Simulating Indefinite Causal Order With Rindler Observers

open access: yesFrontiers in Physics, 2020
Realization of indefinite causal order (ICO), a theoretical possibility that even causal relations between physical events can be subjected to quantum superposition, apart from its general significance for the fundamental physics research, would also ...

Synergies of THESEUS with the large facilities of the 2030s and guest observer opportunities [PDF]

open access: yesExperimental 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 ...

A Potential Foundation for Emergent Space-Time [PDF]

open access: yes, 2014
We present a novel derivation of both the Minkowski metric and Lorentz transformations from the consistent quantification of a causally ordered set of events with respect to an embedded observer.

Teaching middle school physics in Observer-dependence approach: pedagogical and curricular aspects

open access: yesJournal of Physics: Conference Series, 2019
Physics curriculum of middle school and high school is based on the classic perspective of the 19th century and avoids dealing with the concept of observer (frame of reference).

Gauge dependence and self-force from Galilean to Einsteinian free fall, compact stars falling into black holes, Hawking radiation and the Pisa tower at the general relativity centennial [PDF]

open access: yes, 2016
(Short abstract). In Galilean physics, the universality of free fall implies an inertial frame, which in turns implies that the mass m of the falling body is omitted.
