Monitoring Flood Inundation Dynamics From Space

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract With the increasing intensity and frequency of flood events worldwide, the need for accurate and timely inundation mapping has never been more critical. Large‐scale flood extent estimations are vital for coordinating effective disaster response, facilitating recovery, and building future resilience.

Sequence Impedance Modeling and Stability Analysis of dVOC-Based Grid-Forming Inverters with Different Inner-Loop Control Structures

Energies
To elucidate the stability mechanisms of grid-forming (GFM) inverters governed by dispatchable virtual oscillator control (dVOC), this paper develops a comprehensive sequence-impedance modeling and stability analysis framework for dVOC-based GFM ...

Geospatial Analysis of Population Exposure to Flooding in the Sudd Region, South Sudan

Journal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT The Sudd wetland in South Sudan extends over 90,000 km2. Large‐scale flood events in recent years (2019–2022) are said to have led to the displacement of an estimated 1.8 million people in total. However, these estimates are approximate and to date there has not been a systematic analysis of population exposure to flooding in the Sudd region ...

A Systematic Review of Grid-Forming Control Techniques for Modern Power Systems and Microgrids

Energies
Looking toward the future, governments around the world have started to change their energy mix due to climate change. The new energy mix will consist mainly of Inverter-Based Resources (IBRs), such as wind and solar power.

Worlding geographies: A question of languages

Transactions of the Institute of British Geographers, Volume 51, Issue 1, March 2026.
Abstract This intervention responds to the ‘Geography in the World’ series, addressing the question from two angles. Firstly, it shifts the focus from geography in the world to worlding geographies. Drawing on Deleuze and Guattari's concept of ‘becoming‐minority’, it encourages reflection on the current geography of knowledge production as a historical,

Advancing Near‐Real‐Time Flood Inundation Mapping in Australia

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Floods are the second‐most deadly natural hazard in Australia, following heatwaves. Monitoring flood extent and depth in near real‐time (NRT) is crucial to minimize loss of life and socio‐economic impacts. This study leverages advanced computing, data management systems, and high‐quality data, including river gauge data APIs and Australian ...

Megawatt-level converter grid-forming control technology by adopting MPC for medium voltage distribution network

Frontiers in Energy Research
The grid-forming control (GFM) is treated as controlled voltage sources, which can enhance synchronize stability in weak grid case. However, the dynamic response of existing GFM method is limited, and the transient overcurrent in fault is still not ...

Hiding in Plain Sight: Rethinking the Size and Complexity of Iron Age Hillforts in NW Iberia Thanks to Aerial Archaeology and Geophysics

Archaeological Prospection, Volume 33, Issue 1, Page 63-85, January/March 2026.
ABSTRACT This paper tackles one key limitation in the analysis of Iron Age communities in the Northwestern Iberian Peninsula: the limited exploration of areas beyond the fortified settlements known as castros (hillforts). The vast majority of archaeological studies have focused exclusively on the areas inside the walls of these settlements, which are ...

Workflow for the Isolation and Characterisation of Human Milk Extracellular Vesicles (HMEVs) and Their Inflammatory Biomarker Profile

Journal of Extracellular Biology, Volume 5, Issue 1, January 2026.
ABSTRACT Human milk extracellular vesicles (HMEVs), secreted by mammary epithelial cells, are enriched in bioactive molecules that support intestinal epithelial integrity. Among these, oxylipins, that is, lipid mediators derived from polyunsaturated fatty acids, are gaining interest for their immunomodulatory and neuroprotective functions in breastfed ...
