The physics of climate variability and climate change [PDF]
Reviews of Modern Physics, 2020 The climate system is a forced, dissipative, nonlinear, complex and heterogeneous system that is out of thermodynamic equilibrium. The system exhibits natural variability on many scales of motion, in time as well as space, and it is subject to various external forcings, natural as well as anthropogenic.

A Psychophysical Investigation of Size as a Physical Variable [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2016 Physical visualizations, or data physicalizations, encode data in attributes of physical shapes. Despite a considerable body of work on visual variables, "physical variables" remain poorly understood. One of them is physical size. A difficulty for solid elements is that "size" is ambiguous - it can refer to either length/diameter, surface, or volume ...

Physical activity - an important preanalytical variable [PDF]
Biochemia Medica, 2014 The concentration of several biochemical and hematological biomarkers is strongly influenced by a number of preanalytical variables. Several lines of evidence attest that short, middle, and long-term exercise, as well as the relative intensity of physical effort (from mild to strenuous), may influence a broad array of laboratory variables.

Association of day length and weather conditions with physical activity levels in older community dwelling people [PDF]
, 2014 Background: Weather is a potentially important determinant of physical activity. Little work has been done examining the relationship between weather and physical activity, and potential modifiers of any relationship in older people. Wetherefore examined

Social, environmental and psychological factors associated with objective physical activity levels in the over 65s [PDF]
, 2012 Objective: To assess physical activity levels objectively using accelerometers in community dwelling over 65 s and to examine associations with health, social, environmental and psychological factors. Design: Cross sectional survey.

Precise probing and discrimination of third-generation scalar leptoquarks
, 2023 We explore the pair production of third-generation scalar leptoquark at the Large Hadron Collider to next-to-leading order accuracy in QCD, matched to parton shower for a precise probing of the stemming model.

Physics and the Measurement of Continuous Variables [PDF]
Foundations of Physics, 2007 Wigner had expressed the opinion that the impossibility of exact measurements of single operators like position operators rendered the notion of geometrical points somewhat dubious in physics. Using Sewell's recent resolution of the measurement problem (collapse of the wave packet) in quantum mechanics and extending it to the measurement of operators ...
