Green space and physical activity: An observational study using Health Survey for England data [PDF]

Health and Place, 2012
Past studies have suggested that a link between health outcomes and green space is due to increased levels of physical activity of individuals living in areas with more green space.

Active matter in space [PDF]

npj Microgravity, 2022
AbstractIn the last 20 years, active matter has been a highly dynamic field of research, bridging fundamental aspects of non-equilibrium thermodynamics with applications to biology, robotics, and nano-medicine. Active matter systems are composed of units that can harvest and harness energy and information from their environment to generate complex ...

Longitudinal structures of zonal wind in the thermosphere by the ICON/MIGHTI and the main wave sources

Earth, Planets and Space, 2023
In this study, the neutral wind observations from the Michelson Interferometer for Global High-resolution Thermospheric Imaging (MIGHTI) instrument onboard Ionospheric CONnections (ICON) are used to investigate the longitudinal structure of zonal wind ...

Space as an Invention of Active Agents [PDF]

Frontiers in Robotics and AI, 2016
The question of the nature of space around us has occupied thinkers since the dawn of humanity, with scientists and philosophers today implicitly assuming that space is something that exists objectively. Here, we show that this does not have to be the case: the notion of space could emerge when biological organisms seek an economic representation of ...

Magnetic Storms During the Space Age: Occurrence and Relation to Varying Solar Activity [PDF]

, 2022
We study the occurrence of magnetic storms in space age (1957–2021) using Dst and Dxt indices. We find 2,526/2,743 magnetic storms in the Dxt/Dst index, out of which 45% are weak, 40% moderate, 12% intense and 3% major storms.

Driving, Space, and Access to Activity [PDF]

The Journals of Gerontology Series B: Psychological Sciences and Social Sciences, 2015
The definition of health, according to the World Health Organization (WHO), is as follows: “Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.” (WHO, 1948). The interplay of physical and mental health, social interactions, and the environment of an individual contribute to their ...

Solar activity and space weather

Journal of Physics: Conference Series, 2022
Abstract After providing an overview of solar activity as measured by the sunspot number (SSN) and space weather events during solar cycles (SCs) 21-24, we focus on the weak solar activity in SC 24. The weak solar activity reduces the number of energetic eruptions from the Sun and hence the number of space weather events.

Is level of neighbourhood green space associated with physical activity in green space? [PDF]

, 2013
Background There is accumulating evidence that greater availability of green space in a neighbourhood is associated with health benefits for the local population.

Linking long-term switchback variability at 1 au to solar-surface mechanisms: A 27-year statistical study

Astronomy & Astrophysics
Context. Switchbacks–transient, large-angle deflections of the interplanetary magnetic field–pervade the solar wind, yet their origin remains disputed. Current ex situ theories, notably coronal jets and interchange reconnection, are typically tested on ...
