Multidisciplinary Constraints on Magma Compressibility, the Pre‐Eruptive Exsolved Volatile Fraction, and the H2O/CO2 Molar Ratio for the 2006 Augustine Eruption, Alaska

Geochemistry, Geophysics, Geosystems, 2021
Geodetically modeled reservoir volume changes during volcanic eruptions are commonly much smaller than the observed eruptive volumes. This discrepancy is thought to be partially due to the compressibility of magma, which is largely controlled by the ...

Debris-flow monitoring on volcanoes via a novel usage of a laser rangefinder

Journal of Applied Volcanology
Mount Rainier has had at least 11 large lahars over the last 6,000 years, including one occurring without evidence of eruptive activity. This prompted the creation of a lahar detection system that uses a combination of seismic, infrasound, and tripwires.

Comparing self‐reported race and genetic ancestry for identifying potential differentially methylated sites in endometrial cancer: insights from African ancestry proportions using machine learning models

Molecular Oncology, EarlyView.
Integrating ancestry, differential methylation analysis, and machine learning, we identified robust epigenetic signature genes (ESGs) and Core‐ESGs in Black and White women with endometrial cancer. Core‐ESGs (namely APOBEC1 and PLEKHG5) methylation levels were significantly associated with survival, with tumors from high African ancestry (THA) showing ...

Following the tug of the audience from complex to simplified hazards maps at Cascade Range volcanoes

Journal of Applied Volcanology
Volcano-hazard maps are broadly recognized as important tools for forecasting and managing volcanic crises and for disseminating spatial information to authorities and people at risk.

Monitoring eruption activity using temporal stress changes at Mount Ontake volcano

Nature Communications, 2016
Volcanic activity is often accompanied by small earthquakes, with focal mechanisms indicating stress state beneath volcanoes. Here, the authors demonstrate that quantitative evaluation of temporal stress changes is an effective tool for eruption ...

Isogeny volcanoes [PDF]

The Open Book Series, 2013
The remarkable structure and computationally explicit form of isogeny graphs of elliptic curves over a finite field has made them an important tool for computational number theorists and practitioners of elliptic curve cryptography. This expository paper recounts the theory behind these graphs and examines several recently developed algorithms that ...

High-definition and low-noise muography of the Sakurajima volcano with gaseous tracking detectors

Scientific Reports, 2018
Muography is a novel method to highly resolve the internal structure of active volcanoes by taking advantage of the cosmic muon’s strong penetration power.

Escape from TGF‐β‐induced senescence promotes aggressive hallmarks in epithelial hepatocellular carcinoma cells

Molecular Oncology, EarlyView.
Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting
