Measuring environmental exposures in people's activity space: The need to account for travel modes and exposure decay. [PDF]
J Expo Sci Environ Epidemiol, 2023 Background Accurately quantifying people’s out-of-home environmental exposure is important for identifying disease risk factors. Several activity space-based exposure assessments exist, possibly leading to different exposure estimates, and have neither ...

Exploring factors affecting individual GPS-based activity space and how researcher-defined food environments represent activity space, exposure and use of food outlets. [PDF]
Int J Health Geogr, 2021 Background Obesity remains one of the most challenging public health issues of our modern time. Despite the face validity of claims for influence, studies on the causes of obesity have reported the influence of the food environment to be inconsistent ...

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 ...

Gene Regulation: Activation through Space [PDF]
Current Biology, 2016 A recent study visualizes nascent RNAs in live Drosophila embryos to establish a connection between enhancer strength and the frequency of transcriptional bursts. Interestingly, one enhancer can simultaneously activate two core promoters, challenging models of enhancer-core-promoter communication via direct protein-protein contacts.

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.

Progger: an efficient, tamper-evident kernel-space logger for cloud data provenance tracking [PDF]
, 2014 Cloud data provenance, or "what has happened to my data in the cloud", is a critical data security component which addresses pressing data accountability and data governance issues in cloud computing systems. In this paper, we present Progger (Provenance
