When invasions go unnoticed: Public perception of the freshwater jellyfish Craspedacusta sowerbii in Europe

open access: yesPeople and Nature, EarlyView.
Abstract Biological invasions are a major driver of biodiversity loss, yet inconspicuous or “cryptic” species often escape detection and public awareness, limiting management responses. We investigated the freshwater jellyfish Craspedacusta sowerbii, likely native to China and now present on six continents, through a 22‐month multilingual online survey

Efficient and Durable Semitransparent Perovskite Solar Cells for the Application in 4T Perovskite/c‐Si Tandem Devices

open access: yesProgress in Photovoltaics: Research and Applications, EarlyView.
We present an optimized fabrication strategy incorporating a solution‐processed SnO2 buffer layer that prevents sputter‐induced damage during TCO deposition, enabling semitransparent perovskite solar cells with 21.87% efficiency, 27.15% in tandem, and exceptional long‐term stability under continuous illumination and outdoor conditions.

Citizens’ Participation Using Sortition: A practical guide to using random selection to guarantee diverse democratic participation [PDF]

open access: yes, 2018
Sortition is part of our everyday lives. If a deci- sion is to be unbiased and incorruptible as well as guarantee absolute equality of opportunity, it is often decided by random selection.

Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

open access: yessteel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Six-minute walk distance after coronary artery bypass grafting compared with medical therapy in ischaemic cardiomyopathy [PDF]

open access: yes, 2018
Background: In patients with ischaemic left ventricular dysfunction, coronary artery bypass surgery (CABG) may decrease mortality, but it is not known whether CABG improves functional capacity.

Variation in food availability affects the population age structure of Atlantic puffins Fratercula arctica in the Faroe Islands

open access: yesWildlife Biology, EarlyView.
Across their entire Atlantic breeding range, Atlantic puffins Fratercula arctica have experienced decreases in food availability, often leading to population declines. The species is one of the most numerous seabirds in Føroyar (the Faroe Islands, in English) but has faced apparent, unquantified population declines.
