The 2018-ongoing Mayotte submarine eruption: Magma migration imaged by petrological monitoring

, 2021
Deep-sea submarine eruptions are the least known type of volcanic activity, due to the difficulty of detecting, monitoring, and sampling them. Following an intense seismic crisis in May 2018, a large submarine effusive eruption offshore the island of ...

Jaw‐specific stem cell dynamics are associated with distinct enamel architecture in mouse incisors

Developmental Dynamics, EarlyView.
Abstract Background The continuously growing mouse incisor serves as a model for stem cell‐driven tooth renewal. Although mice possess maxillary and mandibular incisors, most studies have focused on the mandible. Potential differences in structure and renewal between these serially homologous organs remain insufficiently characterized.

Volcano collapse along the Aleutian Ridge (western Aleutian Arc) [PDF]

Natural Hazards and Earth System Sciences, 2011
The Aleutian Ridge, in the western part of the Aleutian Arc, consists of a chain of volcanic islands perched atop the crest of a submarine ridge with most of the active Quaternary stratocones or caldera-like volcanoes being located on the northern ...

MNE retrenchment and redeployment in the face of the US–China trade war: Real options and strategic flexibility

Global Strategy Journal, EarlyView.
Abstract Research Summary Trade wars increasingly manifest in the contemporary environment for global business; thereby, calling for examination of MNE strategic responses. MNEs can respond to such shocks by leveraging their strategic flexibility and engaging in retrenchment and redeployment; that is, the respective scaling down (up) of subsidiary ...

The Impacts of Southwest Indian Ocean Tropical Cyclones on Transient Weather in Réunion

International Journal of Climatology, EarlyView.
Tropical cyclones which make passage near Réunion can have significant impacts on transient weather relative to long‐term means on the island. In this paper, these impacts were determined by a topological analysis of non‐landfalling tropical cyclones. The relationship between storm intensity, distance, duration, and seasonality plays an equal role in ...

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.
