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.

Space Climate Manifestation in Earth Prices - from Medieval England Up to Modern Usa [PDF]
, 2004 In this study we continue to search for possible manifestations of space weather influence on prices of agricultural products and consumables. We note that the connection between solar activity and prices is based on the causal chain that includes ...

Ensuring the National Security of Ukraine Through the Standardization of Space Activities [PDF]
Advanced Space Law, 2022 The article analyzes international, including European, and national standards of the process of standardization of space activities. The author reveals the concept of “standard” as one of the main elements of the system of state guarantees of the safety

Capturing Human Activity Spaces [PDF]
Transportation Research Record: Journal of the Transportation Research Board, 2007 “Activity space,” defined as the local areas within which people move or travel during the course of their activities during a specified time period, is a measure of an individual's spatial behavior that captures individual and environmental differences and offers an alternative approach to studying the spatial reach of travelers.

Measuring segregation: an activity space approach [PDF]
Journal of Geographical Systems, 2010 While the literature clearly acknowledges that individuals may experience different levels of segregation across their various socio-geographical spaces, most measures of segregation are intended to be used in the residential space. Using spatially aggregated data to evaluate segregation in the residential space has been the norm and thus individual's ...

Astronomy & AstrophysicsContext. 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 ...
