A matter of time: The importance of the duration of UHT metamorphism
, 2016 The duration of granulite (G) and ultra – high temperature (UHT) conditions in regional metamorphism is critical to arguments regarding the tectonic settings of granulites and their relationships to Supercontinent assembly.

On the significance of short-duration regional metamorphism
Journal of the Geological Society, 2016 Short-duration regional metamorphism is a recently observed and poorly understood phenomenon in metamorphic geology. In this review, it is defined as metamorphism on time scales that limit length scales (of the associated thermal anomaly) to ...

Fluid inclusions in rocks of the Archean high-grade Varpaisjärvi-Lapinlahti area, central Finland [PDF]
Bulletin of the Geological Society of Finland, 1992 Fluid inclusions both in matrix quartz of metamorphic rocks and in quartz veins from five samples from the Archean high-grade Varpaisjärvi-Lapinlahti area were examined with microthermometric methods. Two types of fluid inclusions were observed: CO2-rich

Proceedings of the 33rd Spring Conference on Computer Graphics, 2017 In molecular biology, illustrative animations are used to convey complex biological phenomena to broad audiences. However, such animations have to be manually authored in 3D modeling software, a time consuming task that has to be repeated from scratch for every new data set, and requires a high level of expertise in illustration, animation, and biology.

Identification of PKN2 and MOB4 as Coordinators of Collective Cell Migration
Advanced Science, EarlyView.Through a genetic screen, PKN2 and MOB4 are identified as two proteins regulating the healing of an epithelial model wound. PKN2 promotes collective cell migration by maintaining the cohesion of cell monolayers from their lateral junctions, whereas MOB4 restrains collective cell migration and provides a lamellipodial cue for front‐rear polarity in ...
