An ultraviolet–visible spectroscopy system for studying real‐time pressure effects on enzyme activity

Limnology and Oceanography: Methods, Volume 24, Issue 5, May 2026.
Abstract Investigations of hydrostatic pressure effects on microbial enzymatic processing are challenging but critical for understanding element cycling in the world's oceans. In this study, we developed and tested a stainless‐steel pressure cell capable of withstanding up to 110 MPa of hydrostatic pressure (equivalent to ~ 11,000 m depth), featuring ...

Angle-Polarization Estimation for Coherent Sources with Linear Tripole Sensor Arrays

Sensors, 2016
We propose a parallel factor (PARAFAC) analysis-based angle and polarization estimation algorithm for multiple coherent sources using a uniformly-spaced linear tripole sensor array.

Network Connectivity and Local Hydrology Drive DOM Composition in a Nonperennial Stream

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Nonperennial streams are dynamic sites of biogeochemical processing, yet much remains to be learned about how hydrologic connectivity at different spatial and temporal scales impacts the composition of dissolved organic matter (DOM). We characterized spatial and temporal patterns of DOM composition in a nonperennial prairie stream network ...

Interactions Between O‐Phospho‐L‐Serine and Trivalent Metal Ions: Studies in Solution and Solid State

European Journal of Inorganic Chemistry, Volume 29, Issue 10, 1 April 2026.
The interaction between the phosphorylated amino acid O‐phospho‐L‐serine and trivalent ions of f‐elements such as La3+, Eu3+, and Lu3+, supplemented by Y3+, has been studied in aqueous media. Nuclear magnetic resonance (NMR) spectroscopy in solution and in the solid state examined complex formation from the ligand perspective, while time‐resolved laser‐

The use of analysis of variance and three-way factor analysis methods for studying the quality of a sensory panel [PDF]

, 2007
In sensory analysis a panel of assessors evaluate a collection of samples/products with respect to a number of sensory characteristics. Assessments are collected in a threeway data matrix crossing products, attributes and assessors.

SamBaTen: Sampling-based Batch Incremental Tensor Decomposition

, 2017
Tensor decompositions are invaluable tools in analyzing multimodal datasets. In many real-world scenarios, such datasets are far from being static, to the contrary they tend to grow over time.

Continuous in situ monitoring provides new evidence of storm‐induced riverine hypoxia following climatic extremes

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract June 2023, the warmest June on record at that point in the United Kingdom, was marked by an exceptional warm‐dry period followed by convective storms that triggered pronounced dissolved oxygen (DO) depletion across four river sites spanning a 25–5000 km2 basin gradient.

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).

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
