Maximum Likelihood Solution to the Parafac Model
Behaviormetrika, 1987 The traditional factor analytic view of the PARAFAC model and its extension to a four mode situation with the derivation of the maximum likelihood estimation procedure by the generalized EM algorithm was presented. The four mode model was applied to six ASVAB data matrices defined by three specialty (clerical, mechanical, and electrical), times two ...

Microbial Controls on Dissolved Organic Nitrogen Cycling During Long‐Term Degradation Experiments
Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract Dissolved organic nitrogen (DON) is critical for marine microbial growth by providing carbon and nitrogen. Although DON is rapidly cycled, some compounds within this pool can persist for long‐periods of time. To better understand how DON is cycled by marine microorganisms, we conducted 548‐day incubations using surface‐derived dissolved ...

Journal of Chemometrics, Volume 40, Issue 5, May 2026.ABSTRACT In this study, a new double‐algorithmic chemometric architecture employing continuous wavelet transform (CWT) and parallel factor analysis (PARAFAC) was developed for wavelet‐domain separation of overlapping UV spectra and co‐quantification of analytes in laboratory‐prepared binary mixtures and a commercial tablet formulation.

ChemPhotoChem, Volume 10, Issue 5, May 2026.Herein, we report on a Ba2+ selective, Ba2+ sensitive, and pH stable fluorescent probe with a high photostability in water (cf. TOC). This fluorescent probe is equipped with a dibenzo‐18‐crown‐6 as a highly selective Ba2+ ionophore and a tetramethylated BODIPY fluorophore.

Consensus-based In-Network Computation of the PARAFAC Decomposition
CoRR, 2014 In this work, we present a new approach for the distributed computation of the PARAFAC decomposition of a third-order tensor across a network of collaborating nodes. We are interested in the case where the overall data gathered across the network can be modeled as a data tensor admitting an essentially unique PARAFAC decomposition, while each node only

Arctic Science, 2017 Arctic landscapes are experiencing intense warming and modification of precipitation regimes with climate change. Permafrost disturbances and climate change impacts on hydrology of Arctic watersheds are likely to modify the quantity and composition of ...

Hydrological Processes, Volume 40, Issue 5, May 2026.In the subhumid, wetland‐rich, geologically heterogeneous Boreal Plains region of Canada, we found several controls on stream DOC concentration ([DOC]) and DOM composition: An increase in [DOC] and aromaticity as temperature increases throughout the summer, with temperature trend prevailing over the influence of discharge.

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 ...
