Line-intensity mapping: theory review with a focus on star-formation lines
The Astronomy and Astrophysics Review, 2022Line-intensity mapping (LIM) is an emerging approach to survey the Universe, using relatively low-aperture instruments to scan large portions of the sky and collect the total spectral-line emission from galaxies and the intergalactic medium.

Physics Education, 1978
Some examples are given of the essential measurements which make use of basic physical principles as applied in intensive care units. The associated electronics is not considered. Topics covered comprise oxygen concentration measurement, blood oxygen analysis, ocular microtremor measurement, and automatic fluid balance monitoring.

Intensity interferometry in subatomic physics
Reviews of Modern Physics, 1990The intensity interferometry technique, commonly referred to as the Hanbury-Brown/Twiss effect, has been applied to nuclear and elementary-particle collisions as a method of investigating their space-time evolution. In this review the theoretical framework of the technique is presented, describing the formulations in common use. A survey is made of its

High-Intensity Laser-Atom Physics
2000Publisher Summary This chapter illustrates that the development of lasers capable of delivering short pulses of very intense radiation, over a wide frequency range, has led to the discovery of new, nonperturbative multiphoton processes in laser interactions with atomic systems.

Associations Between Physical Activity Intensities and Physical Function in Stroke Survivors
American Journal of Physical Medicine & Rehabilitation, 2020Purpose Impairment caused by stroke is a major cause of disablement in older adults. Physical activity has been shown to improve physical functioning; however, little research has been done to explore how physical activity of different intensities may affect physical function among stroke survivors.

Impact of Moderate-Intensity and Vigorous-Intensity Physical Activity on Mortality
Medicine & Science in Sports & Exercise, 2018Physical activity guidelines recommend at least 150 min of moderate-intensity physical activity (MPA), 75 min of vigorous-intensity physical activity (VPA), or combination of MPA and VPA. However, few epidemiological studies have examined whether the general population can derive equal health benefits from MPA or VPA.
