Gruppeeksamen som strategisk kommunikation

Cepra-Striben, 2014
Fra 2012 blev gruppeeksamen genindført som lovlig prøveform på alle niveauer af det danske uddannelsessystem. På universitetsniveau repræsenterer genindførelsen en lejlighed til at foretage en universitetspædagogisk refleksion over, hvad det egentligt ...

Distribution of Electrical Resistivity in Single Carbon Fiber Filaments and Its Correlation With Tensile Modulus

Advanced Engineering Materials, Volume 28, Issue 6, 18 March 2026.
A statistical framework is applied to quantify the distribution of electrical resistivity among individual filaments of two commercially available carbon fiber types. Correlations between filament resistivity, tensile modulus, and diameter are examined and complemented by TEM analysis to provide new insight into filament‐level variability relevant for ...

Histone methyltransferase G9a crosstalks with H3K36 histone methyltransferases NSD3 and SETD2 to mediate gene activation

Frontiers in Cell and Developmental Biology
The euchromatic histone methyltransferase G9a/KMT1C/EHMT-II functions as a corepressor and a coactivator of transcription, depending upon its association with distinct protein complexes. While the mechanisms of G9a-mediated repression are well understood,

Atomic‐Scale Insights Into Antisite‐Defect‐Induced Metallicity in Halide Perovskites

Small, Volume 22, Issue 14, 6 March 2026.
Using an aberration‐corrected scanning transmission electron microscope, we identify that the PbCs antisite defect in CsPbBr3 shortens the Pb─Pb bond by ∼20 pm, and induces local strain and polarization, leading to a semiconductor‐to‐metal transition.

Experimental Hypervelocity Dust Impacts in Olivine—Multiscale Insights Into Microcrater Shock and Melting Effects From Coordinated SEM/TEM Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The flux of solar system meteoroids is dominated by objects less than 1 mm in diameter whose impact effects play a major role in the space weathering of airless body surfaces. These effects remain poorly characterized with respect to their dependence on the range of impact speeds for meteoroids across the inner solar system.

Structural characterization of newt tendon regeneration after complete transection: In vivo two‐photon imaging and transmission electron microscopy

Journal of Anatomy, Volume 248, Issue 3, Page 383-394, March 2026.
The present study characterized newt digital flexor tendon regeneration structurally at both micro‐ and nanoscales following complete transection and suggested that the mechanism of tissue regeneration differs between the early phase (until 6 weeks) and the late phase (after 6 weeks). Tendon stubs remained separated for up to 2 weeks after transection,
