Multi-Aspect Incremental Tensor Decomposition Based on Distributed In-Memory Big Data Systems
We propose InParTen2, a multi-aspect parallel factor analysis three-dimensional tensor decomposition algorithm based on the Apache Spark framework. The proposed method reduces re-decomposition cost and can handle large tensors.

Microbial Controls on Dissolved Organic Nitrogen Cycling During Long‐Term Degradation Experiments
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 ...

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.

Maximum Likelihood Solution to the Parafac Model
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 ...

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.

On Kruskal’s uniqueness condition for the Candecomp/Parafac decomposition
The Candecomp/Parafac-decomposition of the real valued three-way array \(X\) is written as \(X=\underline{Y}^{(1)} + \ldots + \underline{Y}^{(R)} +\underline{E}\), where \(\underline{Y}^{(r)}\) are rank one arrays defined as outer products of three specified vectors and \(\underline E\) is a rest term.

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.

Fast adaptive PARAFAC decomposition algorithm with linear complexity [PDF]
We present a fast adaptive PARAFAC decomposition algorithm with low computational complexity. The proposed algorithm generalizes the Orthonormal Projection Approximation Subspace Tracking (OPAST) approach for tracking a class of third-order tensors which have one dimension grow- ing with time.

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 ...
