Drivers of winter Arctic sea ice variability

Winter Arctic sea ice concentration (SIC) variability reflects both anthropogenic warming and internal climate variability, but separating their Arctic signatures remains difficult. Here, we apply Canonical Correlation Analysis to October–March global sea surface temperature and Arctic SIC, 2-m air temperature (T2M), and sea level pressure fields over 1950–2024, to isolate...

The Influence of Reading Intensity on the Ability to Identify Main Ideas in Expository Texts Among Eighth-Grade Students

The ability to identify the main idea in an expository text is one of the essential skills in reading comprehension, which plays a crucial role in learning the Indonesian language.

Lanthanide-doped nanocrystals enable organic room-temperature phosphorescence in solution through direct triplet excitation

Organic triplet excitons are of great interest for applications in optoelectronics, photochemistry and theranostics. Due to spin-selection rules, triplets are ‘dark states’, rendering direct photoexcitation from the ground state and efficient phosphorescent emission nearly impossible. Overcoming these spin-dependent limitations is a long-standing challenge. Here we report a...
