Precession‐Related Variability in North Pacific Deep Water Formation in the Early Eocene: Insights From cGENIE Simulations

Paleoceanography and Paleoclimatology, Volume 41, Issue 9, September 2026.
Abstract Past warmhouse climates differed from the modern ocean circulation regime, with deep‐water formation occurring in regions that are inactive today. Evidence suggests that the North Pacific may have been one such region. The early Eocene, characterized by elevated greenhouse gas concentrations and orbitally paced carbon cycle perturbations ...

Hyperspectral Unmixing With Multi-Scale Convolution Attention Network

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Hyperspectral unmixing is to decompose the mixed pixel into the spectral signatures (endmembers) with their corresponding abundances. However, the ignorance of endmember variability in hyperspectral unmixing results in low performance.

Evaluating Forced Versus Plume‐Induced Subduction Initiation for the Talkeetna‐Bonanza Arc System: Implications for Permo‐Triassic Paleogeography of the North American Cordillera

Tectonics, Volume 45, Issue 9, September 2026.
Abstract The mechanisms by which new subduction zones form remain highly debated. Here we use Permo‐Triassic strata to evaluate potential mechanisms for initiation of the Talkeetna‐Bonanza Arc of the northern North American Cordillera. New mapping and analysis of Permian and Upper Triassic strata on the Alaska Peninsula suggest a period of uplift ...

Modeling the Histogenetic Switch Between Enameloid and Enamel

Evolution &Development, Volume 28, Issue 3, September 2026.
This evo–devo exploration of ~550,000 histogenetic simulations forming dentine, enameloid, and enamel identifies 38 independent ways to induce the enameloid–enamel transition, with delayed matrix vesicle secretion (SVO‐) emerging as the key modification, providing new insights into the origin of enamel in early osteichthyans.

Red to Green: A Lipid Biomarker Record of Tonian‐Ediacaran Algae in Siberia

Geobiology, Volume 24, Issue 5, September/October 2026.
ABSTRACT Multiple lines of evidence point to a major diversification of Eukarya in the late Tonian period, ca. 800–720 Ma ago. Regular steranes, lipid biomarkers primarily sourced from eukaryotes, are first unambiguously reported from multiple sites. Here, we present lipid biomarker stratigraphic records from two drill‐cores from the Lena‐Anabar Basin ...

Radiocarbon Reveals Modern Carbon Exchange With Topsoil Inorganic Carbon in Drylands

Global Change Biology, Volume 32, Issue 9, September 2026.
Radiocarbon measurements across drylands reveal that topsoil inorganic carbon carries a measurable modern carbon signature linked to soil pH and organic carbon pools. This modern imprint weakens with increasing aridity and soil depth, indicating reduced exchange with contemporary carbon sources under drier conditions and in deeper soils.

Phase Equilibria and Thermodynamic Modeling of the “Cu2O”–FeO–Fe2O3–Al2O3–SiO2 System in Equilibrium With Metal

Journal of the American Ceramic Society, Volume 109, Issue 9, September 2026.
ABSTRACT The phase equilibria of the “Cu2O”–FeO–Fe2O3–Al2O3–SiO2 system in equilibrium with metal were studied as part of the investigation of the 20‐component PbO–ZnO–Cu2O–FeO–Fe2O3–CaO–SiO2–Al2O3–MgO–S–(As, Sn, Sb, Bi, Ag, Au, Ni, Cr, Co, and Na as minor elements) slag/matte/metal/speiss/gas system in support of the operation/development of existing ...

A new approach for endmember extraction and clustering addressing inter- and intra-class variability via multi-scaled-band partitioning

, 2016
In this paper a new method is introduced for detecting and clustering spectrally similar but physically distinct materials. The method exploits the spectral information by dividing the spectral domain into band subsets whose width vary from broad to ...

Drastic Biodiversity Transition as a Function of Rainfall Patterns: From Coastal Drylands to Amazonian Rainforests

Journal of Biogeography, Volume 53, Issue 9, September 2026.
ABSTRACT Aim By moving beyond traditional biome‐centric approaches to sample continuously across a massive ecotone, we investigate how species richness, community composition, and dominance of woody plants change across a strong longitudinal precipitation gradient and identify thresholds in water availability that drive shifts in community assembly ...

Modelling Spatial and Temporal Controls on Leaky Wooden Dam Effectiveness for Catchment‐Scale Flood Mitigation in an Upland Catchment

Journal of Flood Risk Management, Volume 19, Issue 3, September 2026.
ABSTRACT Natural Flood Management (NFM) is increasingly adopted as a sustainable strategy for mitigating flood risk. Among these measures, the installation of leaky wooden dams (LWDs) at catchment scale is a widely used intervention aimed at slowing flow and desynchronising runoff peaks between sub‐catchments, thereby reducing flood magnitude.
