Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract Evaluating multiple competing biotic and abiotic processes and how they interact with carbon dioxide (CO2) in aquatic systems, is critical to understanding regional and global carbon cycles. Here, we used an aquatic continuum of the Bahe watershed, within a semi‐arid region, to establish a comprehensive conceptual framework for identifying CO2

An Algebraic Solution for the Candecomp/PARAFAC Decomposition with Circulant Factors [PDF]
SIAM Journal on Matrix Analysis and Applications, 2014 The Candecomp/PARAFAC decomposition (CPD) is an important mathematical tool used in several fields of application. Yet, its computation is usually performed with iterative methods which are subject to reaching local minima and to exhibiting slow convergence.

Journal of Chemometrics, Volume 40, Issue 6, June 2026.ABSTRACT ANOVA simultaneous component analysis (ASCA) is the current state‐of‐the‐art chemometric tool for analyzing and interpreting high‐dimensional experimental data from a design of experiments (DoE). Being a multivariate extension of the ANOVA, ASCA makes a perfect tandem with DoE.

Cramer-Rao Bound and Fitting Algorithm for PARAFAC Decomposition Under Constant-Modulus Constraints
工程科学与技术, 2009 :To analyze the parameter estimation performance of PARAFAC decomposition under Constant Modulus (CM) constraint, Cramer Rao Bound (CRB) expressions for PARAFAC decomposition under “First Row Known” and CM constraints were proposed.

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.

Species‐specific processing of fluorescent dissolved organic matter by Caribbean sponges
Limnology and Oceanography, Volume 71, Issue 6, June 2026.Coral reefs are biodiverse and productive ecosystems that are found in typically oligotrophic environments. Many studies have attempted to explain this paradox by demonstrating that microbial symbionts expand metabolic capabilities of host animals.

Carbon source and weather in coastal North Carolina
Limnology and Oceanography, Volume 71, Issue 6, June 2026.Abstract The increasing frequency of extreme weather events, including tropical cyclones, is altering the delivery and quality of organic matter (OM) exported from landscapes to estuaries. However, the mechanisms regulating these shifts, especially during multi‐year climatic oscillations, remain poorly understood.
