A novel physiological role for ARF1 in the formation of bidirectional tubules from the Golgi. [PDF]

, 2017
Capitalizing on CRISPR/Cas9 gene-editing techniques and super-resolution nanoscopy, we explore the role of the small GTPase ARF1 in mediating transport steps at the Golgi.

Recent advances in stimulated emission depletion (STED) super-resolution microscopy for in vivo imaging [PDF]

APL Photonics
Recent advances in stimulated emission depletion (STED) microscopy have resulted in breakthroughs in biological imaging. Such advances include three-dimensional (3D) imaging, aberration correction to enhance resolution at depth in tissue, reduction in ...

Kverneland og Fiske på sporet: Re-tracing som værktøj for kunstnerbiografien i tegneserier

Kunst og Kultur, 2017
De norske tegneserieskabere Lars Fiske og Steffen Kverneland har haft et langt samarbejde, hvor de laver kunstnerbiografier i tegneserieform. Jeg undersøger deres metode og argumenterer for, at de anvender en dobbelt “re-tracing” strategi til at ...

Stratification relieves constraints from steric hindrance in the generation of compact acto-myosin asters at the membrane cortex [PDF]

, 2020
Recent in-vivo studies have revealed that several membrane proteins are driven to form nanoclusters by active contractile flows arising from F-actin and myosin at the cortex. The mechanism of clustering was shown to be arising from the dynamic patterning

Naturforhold og trædesten til pædagogik for bæredygtighed i dagtilbud

Forskning i Pædagogers Profession og Uddannelse
Artiklen viser hvordan dominerende kulturelle forestillinger om børn og natur kan udgøre en barriere for hvem der inviteres til hvad, når der arbejdes med naturpædagogik i dagtilbud.

Analytical description of high-aperture STED resolution with 0-2$\pi$ vortex phase modulation

, 2013
Stimulated emission depletion (STED) can achieve optical super-resolution, with the optical diffraction limit broken by the suppression on the periphery of the fluorescent focal spot.

«Dette er måten de unge snakker på i dag.» Om elevers bruk av hatprat og nedsettende ytringer

Nordisk tidsskrift for pedagogikk og kritikk
Artikkelen er basert på en empirisk undersøkelse av hvordan lærere og fagarbeidere ved en kombinert barne- og ungdomsskole erfarer og håndterer hatprat og nedsettende ytringer blant elever når dette oppfattes som forstyrrende for skolens undervisning og

Background reduction in STED-FCS using coherent-hybrid STED [PDF]

, 2020
AbstractFluorescence correlation spectroscopy (FCS) is a valuable tool to study the molecular dynamics of living cells. When used together with a super-resolution stimulated emission depletion (STED) microscope, STED-FCS can measure diffusion processes at the nanoscale in living cells. In twodimensional (2D) systems like the cellular plasma membrane, a

Deep learning enables fast, gentle STED microscopy

Communications Biology, 2023
STED microscopy is widely used to image subcellular structures with super-resolution. Here, we report that restoring STED images with deep learning can mitigate photobleaching and photodamage by reducing the pixel dwell time by one or two orders of ...

Strategies for Searching Video Content with Text Queries or Video Examples [PDF]

, 2016
The large number of user-generated videos uploaded on to the Internet everyday has led to many commercial video search engines, which mainly rely on text metadata for search. However, metadata is often lacking for user-generated videos, thus these videos
