Vision at high latitudes: High sensitivity without specific boreal adaptations in photoreception in reindeer (Rangifer tarandus L.)

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The light climate at high latitudes, in particular the extended twilight of winter and the reduced diel variation in light level in midsummer and midwinter, potentially constrains visual function and the synchronisation of temporal organisation in polar species.

Time poetics and ageing in the Ik mountains: seeing time disappear Poétique du temps et vieillissement dans les montagnes des Iks : voir le temps disparaître

Journal of the Royal Anthropological Institute, EarlyView.
In the Ik mountains in Uganda, only few old people still have the skills to ‘see time’ with sundials. Common ways of knowing time and age now include phones and ID cards in digital registers. I follow the elder seer Komol to explore how changing the measures of time influences the experience of time and age. How do being a ‘time being’ and ideas about ‘

Highlight Talk from Super-Kamiokande

Universe, 2019
Super-Kamiokande (SK), a 50 kton water Cherenkov detector in Japan, is observing both atmospheric and solar neutrinos. It is also searching for supernova (relic) neutrinos, proton decays and dark matter-like particles. A three-flavor oscillation analysis

Weichselian–Holocene glacial history of the Sjuøyane archipelago, northern Svalbard

Boreas, EarlyView.
To reconstruct the glacial history of Sjuøyane, we describe coastal sedimentary sections in Quaternary sediments and constrain their chronology by radiocarbon and optically stimulated luminescence ages. The sedimentary sections largely consist of shallow (glacio‐)marine and/or littoral sediments deposited during high relative sea levels.

Neural networks for separation of cosmic gamma rays and hadronic cosmic rays in air shower observation with a large area surface detector array

Machine Learning: Science and Technology
The Tibet AS γ experiment has been observing cosmic gamma rays and cosmic rays in the energy range from teraelectron volts to several tens of petaelectron volts with a surface detector array since 1990.

Cosmic ray acceleration

Astroparticle Physics, 2013
This review describes the basic theory of cosmic ray acceleration by shocks including the plasma instabilities confining cosmic rays near the shock, the effect of the magnetic field orientation, the maximum cosmic ray energy and the shape of the cosmic ray spectrum.

An empirical vegetation correction for soil water content quantification using cosmic ray probes

, 2015
Cosmic ray probes are an emerging technology to continuously monitor soil water content at a scale significant to land surface processes. However, the application of this method is hampered by its susceptibility to the presence of aboveground biomass ...
