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.

Submarine cores record magma evolution toward a catastrophic eruption at Kikai Caldera

Communications Earth & Environment
Magma evolution toward a caldera-forming eruption remains uncertain in many cases owing to the lack of successive volcanic records before catastrophic eruptions.

Impact of submarine volcanic versus hydrothermal activity onto the strontium and lithium isotopic signatures of the water column (TONGA)

Frontiers in Marine Science
During the TONGA cruise (2019), seawater samples were collected to assess the effect of volcanic eruption versus submarine hydrothermal system on the water column.

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 ...

Multi-stage volcanic island flank collapses with coeval explosive caldera-forming eruptions

Scientific Reports, 2018
Volcanic flank collapses and explosive eruptions are among the largest and most destructive processes on Earth. Events at Mount St. Helens in May 1980 demonstrated how a relatively small (300 km3), but can also occur in complex multiple stages.

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 ...

BATHYMETRIC SOUNDING by REMOTE SENSING Using ELECTROMAGNETIC RADIATION [PDF]

Science of Tsunami Hazards, 2016
We describe a novel modus operandi to survey the ocean floor. We utilize the eruption of submarine volcanoes as a light source. The electromagnetic radiation emitted by such eruptions illuminate the ocean floor and thus provides information about the ...

Late Holocene environmental history of Dojran, Macedonia: Investigating the interplay of imperial dynamics and climatic change

Journal of Quaternary Science, EarlyView.
ABSTRACT This study presents a high‐resolution, multi‐proxy reconstruction of environmental and land‐use change from Lake Dojran over historical times (last 2500 years), combining pollen, biomarkers, radiocarbon dating, Ottoman taxation records and other historical data.

Giant offshore pumice deposit records a shallow submarine explosive eruption of ancestral Santorini

Communications Earth & Environment
Large explosive volcanic eruptions from island arcs pour pyroclastic currents into marine basins, impacting ecosystems and generating tsunamis that threaten coastal communities and infrastructures.

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.
