Modelling Patterns of Past Inundation Processes Combining Geoarchaeology and Morphometric Hydrological Analysis in the Shashe‐Limpopo Basin, South Africa

Archaeometry, EarlyView.
ABSTRACT Riverine and valley systems across the globe have been central to the development of past urban centres. By AD 900, the Shashe and Limpopo Rivers seem to have facilitated the interaction and integration of early farming communities in southern Africa. This paper focuses on the application of geoarchaeological perspectives made available by the

From the Ground to the Stars: The Vertical Politics of the EU Drone Wall and Airspace Defence

JCMS: Journal of Common Market Studies, EarlyView.
Abstract This research note analyses the European Commission's Defence Readiness Roadmap 2030 as a manifestation of a new spatial and technological logic of European defence: the vertical territorialisation of security. Moving beyond traditional perimeter‐based understandings of territorial defence, the Roadmap constructs a multi‐layered continuum ...

Crawling under the radar: Two novel Paulinella species expand knowledge about the ecology and evolution of a primary plastid‐containing amoeba lineage

Journal of Phycology, EarlyView.
Abstract The genus Paulinella represents a rare, independent case of primary endosymbiosis, providing a unique system to study the early stages of organelle evolution. Here, we expand current understanding of primary plastid endosymbiosis through the discovery and characterization of two novel photosynthetic amoebae, Paulinella marae sp. nov.

A Survey of Density Estimation for SAR Images [PDF]

, 2012
Modeling of synthetic aperture radar (SAR) images has been an important topic of research since the inception of SAR satellites. Many theoretical and empirical models have been presented in literature to accurately model the amplitude SAR images. The

Mesophotic octocoral larval settlement preferences and behaviors

Restoration Ecology, EarlyView.
Abstract Introduction Lab‐based coral reproduction is advancing restoration efforts to support coral populations injured by the 2010 Deepwater Horizon oil spill. Objectives This study aimed to answer foundational questions concerning coral spawning and larval settlement that need to be resolved for these mesophotic and deep‐sea coral species before ...

Electrified Carbon‐Neutral Methanol Production Pathways: A Multiscale Techno‐Economic‐Environmental Assessment Based on the UK Energy System

Advanced Chemical Engineering, Volume 1, Issue 2, December 2026.
A two‐scale framework bridges process‐level physics and system‐level decision‐making for electrified green methanol production. Replacing computationally demanding reactor simulations with an interpretable symbolic‐regression surrogate enables rapid techno‐economic and life‐cycle assessment. The framework reveals how process performance propagates into

Freshwater Biodiversity Research in Brazil: Trends from a Systematic Review and Topic Modeling

International Review of Hydrobiology, Volume 111, Issue 2, December 2026.
ABSTRACT Brazil is a megadiverse country that hosts six major biomes and a vast freshwater network. Despite this richness, research on freshwater biodiversity has been heterogeneous across regions, communities, and time, leaving significant knowledge gaps.

A Simple Method of Estimating Wave Height Based on Shadowing in X-Band Radar Images

Journal of Marine Science and Engineering
X-band marine radar shadow features are widely applied to wave height estimation. Since the shadow fraction rises with the distance from the radar antenna, wave slope estimation is sensitive to the selected analysis region.
