Late Holocene environmental history of Dojran, Macedonia: Investigating the interplay of imperial dynamics and climatic change

Journal of Quaternary Science, EarlyView.
ABSTRACT This study presents a high‐resolution, multi‐proxy reconstruction of environmental and land‐use change from Lake Dojran over historical times (last 2500 years), combining pollen, biomarkers, radiocarbon dating, Ottoman taxation records and other historical data.

The advance of El Niño phase locking from period 1982–2000 to 2001–2022

Environmental Research Communications
The mature phases of El Niño-Southern Oscillation (ENSO) events exhibit a distinct tendency to peak towards the end of the calendar year, a phenomenon commonly referred to as ENSO phase locking.

Establishing Monthly Benchmarks for Erosion Control and Vegetation Restoration Targets Across the Loess Plateau

Land Degradation &Development, EarlyView.
ABSTRACT Establishing scientifically grounded soil erosion control targets and feasible vegetation restoration strategies is crucial for high quality development of the Chinese Loess Plateau which is severely affected by soil erosion. Currently, the commonly used tolerable soil loss (TSL) is inadequate for addressing the spatial heterogeneity in ...

Atmospheric impact of the 1783–1784 Laki Eruption: Part II Climatic effect of sulphate aerosol [PDF]

Atmospheric Chemistry and Physics, 2003
The long 1783-1784 eruption of Laki in southern Iceland, was one of the first eruptions to have been linked to an observed climate anomaly, having been held responsible for cold temperatures over much of the Northern Hemisphere in the period 1783-1785.

Nonstationarity in wildlife disease dynamics: insights from the prairie dog–plague system

Oikos, EarlyView.
Ecological relationships often vary in strength and direction across ecosystems, a pattern that has become increasingly evident as ecology expands to broader spatial and temporal scales. Although such nonstationarity – the changing effect of predictor variables across spatiotemporal contexts – is widely acknowledged in ecological research, it has ...

Ensemble reliability and the signal‐to‐noise paradox in ECMWF subseasonal forecasts

Quarterly Journal of the Royal Meteorological Society, EarlyView.
We derive a general expression for the ratio of predictable components (RPC) in terms of correlation, spread–error ratio, and total variance ratio. Physical constraints on the admissible solutions (i.e., real‐valued and non‐negative variances) provide a mechanism to identify statistically paradoxical sample combinations of reliability and correlation ...

A framework to evaluate and identify development requirements for land‐surface models at km‐scale resolution: Application to a semi‐arid and mountainous region

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This article provides a first evaluation of land‐surface models at the km‐scale resolutions at which they are used in weather and Earth‐system models. At these resolutions, the lateral transfers of water that organize landscapes play an important role in predicting evaporation correctly. Riparian processes and human water management for irrigation need

Unsupervised Anomaly Detection in Hospital Financial Statements: A Multi-Algorithm Consensus Approach With Explainable AI

IEEE Access
Monitoring the financial health of hospitals is critical for healthcare sustainability, yet traditional approaches rely on supervised learning methods that require labeled datasets—an assumption rarely met in practice.

High‐Efficiency Lithium Sulfur Cells With Suppressed Polysulfide Solubility Using a Cost‐Effective Ammonium‐Based Ionic Liquid Electrolyte

Small, EarlyView.
The cost‐effective ammonium‐based ionic liquid electrolyte, N₁₁₁3FSI, suppresses polysulfide dissolution to sub‐millimolar levels in lithium–sulfur batteries. The electrolyte promotes efficient FSI− anion reduction, forming a dense, LiF‐rich solid‐electrolyte interphase on both the lithium metal anode and sulfur cathode. This dual‐electrode passivation

Leakage-aware benchmarking of temporal data preparation for hourly energy forecasting

Energy Conversion and Management: X
Hourly energy forecasting performance depends not only on the prediction model but also on how temporal data are prepared before learning. In practice, choices such as lookback-window length, scaling, calendar encoding, categorical treatment, and anomaly
