Glacial Meltwater Promotes Biological Productivity and Subsequent Dissolved Organic Carbon Accumulation in the Eastern Ross Sea: Evidence From the Austral Summer of 2023

Global Biogeochemical Cycles, Volume 40, Issue 3, March 2026.
Abstract The Ross Sea, a critical region for global carbon cycling, receives increasing glacial meltwater from West Antarctica, yet the impact on regional carbon cycling remains poorly understood. A key uncertainty is how this meltwater influences dissolved organic matter (DOM), particularly in the historically inaccessible eastern Ross Sea. This study

Dissolved Organic Matter Composition in the Laurentian Great Lakes Ice and Its Contribution to Spring Melt

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract Dissolved organic matter (DOM) plays a vital role in lakes, but its behavior in winter is poorly understood. This study examined the differences in DOM between lake ice and the upper water column across 18 sites in the Laurentian Great Lakes, integrating in situ sampling and remotely sensed ice data to create a mass budget model to estimate ...

A New Approach of Oil Spill Detection Using Time-Resolved LIF Combined with Parallel Factors Analysis for Laser Remote Sensing

Sensors, 2016
In hope of developing a method for oil spill detection in laser remote sensing, a series of refined and crude oil samples were investigated using time-resolved fluorescence in conjunction with parallel factors analysis (PARAFAC).

Colored Plastic Pollution Reshapes Aquatic Microbial Community and Resistance Profile via Divergent Pseudonatural Dissolved Organic Matter

Advanced Science, Volume 13, Issue 3, 14 January 2026.
By altering the quantity and chemical composition of polyethylene‐derived dissolved organic matter, plastic color dynamically regulates bacterial metabolic interactions, thereby reshaping community resistance expression and facilitating the dissemination of antibiotic resistance.

Comparative Binding Studies of the Chelators Methylolanthanin and Rhodopetrobactin B to Lanthanides and Ferric Iron

ChemBioChem, Volume 27, Issue 1, January 2026.
The synthesis and the investigation of the lanthanide (Ln) and Fe‐binding properties of the putative lanthanophore methylolanthanin (MLL) and the siderophore rhodopetrobactin B (RPB B) are reported. While both chelators bind Lns, they unexpectedly precipitate with Lns under biologically relevant conditions and thereby challenge the proposed classic ...

Use of Fluorescence Spectroscopy and Chemometrics to Visualise Fluoroquinolones Photodegradation Major Trends: A Confirmation Study with Mass Spectrometry

Molecules, 2023
In this work, we employed EEM-PARAFAC (fluorescence excitation-emission matrices-parallel factor analysis) as a low-cost tool to study the oxidation pathways of (fluoro)quinolones. Amounts of 12.5 μM of enrofloxacin (ENR), ciprofloxacin (CIP), ofloxacin (

FDA‐MIMO Range and Angle Estimation Based on Hybrid Tensor Ring and CP Decomposition

Electronics Letters, Volume 62, Issue 1, January/December 2026.
The graphical abstract illustrates the RMSE performance of range and angle estimation versus SNR for different array configurations. The proposed method consistently achieves lower estimation error than existing approaches and closely matches the Cramér‐Rao bound across the entire SNR range, demonstrating its superior accuracy.

An Approach of Highway Toll Revenue Calculation Based on the Prediction of OD Matrix

Journal of Advanced Transportation, Volume 2026, Issue 1, 2026.
Accurate toll revenue calculation is essential for highway operation management and construction planning. Reliable forecasting requires a thorough understanding of evolving traffic flow patterns and regional origin–destination (OD) distributions. However, challenges such as incomplete data collection and difficulties in capturing transit traffic ...
