Pattern and process of vegetation change (succession) in recent volcanic landscapes of New Zealand and Hawaii [PDF]

, 2010
Volcanic activity (including lava flows, debris flows and tephra eruptions) is a regular feature of many landscapes of the North Island of New Zealand and the Hawaiian archipelago.

Droughts and human impact in the ancient Uaymil region of the Maya lowlands inferred from a 2800‐year sedimentary archive at Lake Kaná, Mexico

Boreas, EarlyView.
The relationship between the climate and societal transformation in Maya lowlands has long been debated, particularly the role of drought in shaping the civilization trajectory during the Classic Period. A high‐resolution, multi‐proxy, geochemical record from Lake Kaná, located in the underexplored Uaymil region of the Yucatán Peninsula in Mexico ...

Enhanced P-wave velocity imaging by marine airgun-source seismic surveys with distributed acoustic sensing

Scientific Reports
P-wave velocity (Vp) structures in marine areas have been estimated using marine airgun-source seismic surveys and refraction methods. The lateral resolution of Vp structures depends on the number of receivers and shots.

Initial atmospheric conditions control transport of volcanic volatiles, forcing and impacts [PDF]

Atmospheric Chemistry and Physics
Volcanic eruptions impact the climate and environment. The volcanic forcing is determined by eruption source parameters, including the mass and composition of volcanic volatiles, eruption season, eruption latitude, and injection altitude.

CO2-crystal wettability in potassic magmas. Implications for eruptive dynamics in light of experimental evidence for heterogeneous nucleation. [PDF]

, 2017
The volatile content in magmas is fundamental for the triggering and style of volcanic eruptions. Carbon dioxide, the second most abundant volatile component in magmas after H2O, is the first to reach saturation upon ascent and depressurization.

Authoring Terrestrial Planets with Diffusion Models

Computer Graphics Forum, EarlyView.
Abstract To support the design and subsequent generation of terrestrial planets for use in the creative media, we propose a solution that employs a generative model trained on satellite data from planetary bodies with a defined solid surface, such as the Earth and Mars.

Winter warming from large volcanic eruptions [PDF]

An examination of the Northern Hemisphere winter surface temperature patterns after the 12 largest volcanic eruptions from 1883-1992 shows warming over Eurasia and North America and cooling over the Middle East which are significant at the 95 percent ...

Toward Forecasting Volcanic Eruptions using Seismic Noise

, 2007
During inter-eruption periods, magma pressurization yields subtle changes of the elastic properties of volcanic edifices. We use the reproducibility properties of the ambient seismic noise recorded on the Piton de la Fournaise volcano to measure relative

Single‐Cell Virtual Perturbation Screening Identifies STAT3 as a Key Regulator of Dentinogenesis

Cell Proliferation, EarlyView.
STAT3 promotes odontoblast differentiation in dental mesenchymal cells by transcriptionally regulating WNT2B via the canonical Wnt/β‐catenin signalling pathway. These findings elucidate a mechanism underlying dentine development. ABSTRACT Dentine formation constitutes a physiological process precisely regulated by signal transduction modules governing ...

Role of a Hidden Fault in the Early Process of the 2024 Mw7.5 Noto Peninsula Earthquake

Geophysical Research Letters
The 2024 Mw 7.5 Noto Peninsula, Japan, earthquake was initiated within the source region of intense swarm activity. To reveal the mainshock early process, we relocated the earthquake hypocenters and found that many key phenomena, including the mainshock ...
