Consensus and persistent uncertainty in fetal ventriculomegaly: Delphi study mapping unresolved clinical domains and research priorities

Objectives: Fetal ventriculomegaly (VM) is a common prenatal finding with heterogeneous etiology and unpredictable outcome, yet its management remains among the least standardized in fetal medicine. This study aimed to establish expert consensus on key decision points in the prenatal management of fetal VM, and to systematically map the domains of persistent uncertainty as a structured framework for future research priorities. Methods: A two-round modified Delphi study was conducted with an i...

Impacts of climate and land use changes on water retention in the transboundary Yuanjiang-Red River Basin: Historical attribution and future projections

Study region: the Yuanjiang–Red River Basin (YRRB), Southeast Asia. Study focus: Water retention (WR) capacity in the transboundary YRRB has been increasingly affected by combined climate and land-use changes. However, limited quantitative attribution of historical drivers and uncertain future projections hinder the development of effective cross-border adaptation strategies. This study integrated the Variable Infiltration Capacity model, a fixed-varying scenario design, and variable-specific...

Concurrent superimposed ice formation and meltwater runoff on Greenland’s ice slabs

Rivers and slush fields on the Greenland Ice Sheet increasingly develop in locations where the accumulation zone hosts near-impermeable ice slabs. However, the division between runoff versus retention in these areas remains unmeasured. We present field measurements of superimposed ice formation onto slabs around the visible runoff limit. The quantity of superimposed ice varies by proximity to visible surface water and the surface slope, highlighting that meltwater can flow laterally before re...

A computationally efficient statistically downscaled 100 m resolution Greenland product from the regional climate model MAR

The Greenland Ice Sheet (GrIS) has been contributing directly to sea level rise, and this contribution is projected to accelerate over the next decades. A crucial tool for studying the evolution of surface mass loss (e.g., surface mass balance, SMB) consists of regional climate models (RCMs), which can provide current estimates and future projections of sea level rise associated with such losses. However, one of the main limitations of RCMs is the relatively coarse horizontal spatial resoluti...

Agile Diagnosis of Active Systems by Condensed Abduction

Automation of diagnosis has been addressed since the dawn of AI, both in medical and industrial domains. This paper focuses on model-based diagnosis of a class of asynchronous discrete-event systems (DESs), called active systems, which can also be an abstract representation of continuous dynamical systems, such as automobiles, power networks, or nuclear plants. In that context, diagnosis is abduction-based, where the behavior of a DES that conforms with a given temporal observation needs to b...
