Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Explaining the dynamics of the sub-relativistic electron third belt in the Earth’s radiation belts by using medium Earth orbit satellite observations

open access: yesEarth and Planetary Physics
The Earth’s electron radiation belts typically exhibit a two-belt structure. However, observations from the Van Allen Probes revealed the existence of a three-belt structure.

Optical Signatures of the Outer Radiation Belt Boundary

open access: yesGeophysical Research Letters, 2019
We present observations that show structured diffuse aurora (SDA) correlated with electron precipitation directly from the outer boundary of the outer radiation belt.

High‐Throughput Geocoding to Assess Short‐Term Air Pollution in Correlation With Mortality in a French Cancer Patient Cohort

open access: yesInternational Journal of Cancer, EarlyView.
Although chronic air pollution exposure is linked to lung cancer mortality, the short‐term effects of fluctuating air quality on overall cancer mortality remain uncertain. Here, the authors applied geomatics and machine‐learning models to retrospectively examine possible associations between 31‐day pollution exposure and mortality in a French cancer ...

Microbiome and aging: Trajectories of microbiome age across human ecosystems and their systemic effects

open access: yesiMeta, EarlyView.
Microbiome age (MA) has emerged as an innovative biomarker of biological aging, reflecting host aging trajectories through dynamic alterations in microbial composition, function, and host–microbe interactions across multiple body ecosystems. Diverse computational strategies—including traditional machine learning, deep learning, and multi‐omics ...

Combined Effects of Equatorial Chorus Waves and High‐Latitude Z‐Mode Waves on Saturn's Radiation Belt Electrons

open access: yesGeophysical Research Letters, 2019
In this paper, we examined the combined effects of equatorial chorus waves and high‐latitude Z‐mode waves on the energy and pitch angle distribution of Saturn's radiation belt electrons.

Compressed Sensing‐Accelerated 3.0 T Noncontrast‐Enhanced CMRA: Diagnostic Efficacy for Coronary Artery Stenosis

open access: yesiRADIOLOGY, EarlyView.
This bar chart illustrates the diagnostic performance of coronary magnetic resonance angiography (CMRA) for detecting ≥ 50.00% coronary artery stenosis at the segment, vessel, and patient levels, including sensitivity, specificity, positive predictive value, negative predictive value, and accuracy.

Intrafraction motion and impact of margin reduction for MR‐Linac online adaptive radiotherapy for pancreatic cancer treatments

open access: yesJournal of Medical Radiation Sciences, Volume 72, Issue 1, Page 17-24, March 2025.
This analysis included quantification of intrafraction motion in pancreas stereotactic ablative radiotherapy treated on the MR‐Linac, leading to the development of adjusted (PTV) margins. Intrafraction motion indicated an average target displacement of 1–3 mm, resulting in an adjusted PTV margin of 2 mm in the right–left and superior–inferior ...

Evaluating Reference Evapotranspiration (ETo) Calculation Methods and Quantifying Climate‐Driven Change in Irrigation Demand Across Nepal's Terai

open access: yesInternational Journal of Climatology, EarlyView.
Framework illustrating the comparison of different reference evapotranspiration (ETo) estimation methods and the integration of baseline ETo, crop water requirement (CWR), and irrigation water requirement (IWR) calculations with downscaled CMIP6 climate projections under SSP245 and SSP585 scenarios for the mid‐century and late‐century periods across ...

Observed Linkages Between Marine Heatwaves and Extreme Weather Over Land: A New Zealand Case Study

open access: yesInternational Journal of Climatology, EarlyView.
Marine heatwaves consistently warm New Zealand's land surface, but rainfall impacts occur only when synoptic systems enable moisture transport. This 38‐year analysis shows MHWs act as thermodynamic background drivers of heat and conditional amplifiers of extreme rainfall events or droughts.
