Radiation‐Induced Degradation in Polymeric Materials: Alterations in Physical–Chemical Properties and Their Effects on Electrical Performance of Insulation Systems

High Voltage, EarlyView.
ABSTRACT This paper investigates the effects of radiation on polymeric materials used as insulation systems in electrical equipment such as cables for nuclear and particle accelerator applications. After a detailed description of the physics of radiation‐induced damage in the polymeric matrix, a comprehensive analysis of the physical–chemical and ...

Hedgehog: An Isolated Quiescent Dwarf Galaxy at 2.4 Mpc

The Astrophysical Journal Letters
It is well known that almost all isolated dwarf galaxies are actively forming stars. We report the discovery of dw1322m2053 (nicknamed Hedgehog), an isolated quiescent dwarf galaxy at a distance of 2.40 ± 0.15 Mpc with a stellar mass of M _⋆ ≈ 10 ^5.8 M ...

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. In this

Phenological turnover matters when making trait‐based predictions of plant–pollinator interactions

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Understanding the processes determining species' interactions is key to predicting and safeguarding ecological networks under rapid environmental change. One approach to estimating interactions is to use morphologies of taxa interacting across trophic levels to reveal ...

Hydrostatic Equilibrium Constraints in X-COP Galaxy Clusters: Testing Hyperconical Modified Gravity in Hot-gas-dominated Regions

The Astrophysical Journal
Modified Newtonian dynamics (MOND) was originally proposed to model galaxy rotation curves without dark matter. However, MOND presents difficulties in explaining the radial acceleration relation observed in galaxy clusters, and moreover, it does not ...

From cities to refuges for pollinators: Urban practices for enhancing pollinator habitats in changing landscapes

Journal of Applied Ecology, EarlyView.
A framework for the support of pollinators in urban areas is developed here, based on five pillars: nesting, flower resources, artificial support, management and society acceptance, with additional key elements from science and society. Society should incorporate strategies for pollinators as in this framework by means of co‐planning with stakeholders,

‘FROM GHETTO TO HABITUS FACTORY’ ROMA CAMPS IN ITALY: An Empirical Extension of Loïc Wacquant's Theorization

International Journal of Urban and Regional Research, EarlyView.
Abstract In this article we apply Wacquant's conceptualization of the ghetto to an analysis of interviews conducted with Roma people living in the state‐enforced camps of Turin, Italy. We illustrate how the elements characterizing a ghetto according to Wacquant (i.e.
