Solving an Augmented Nonnegative Matrix Factorization Model by Modified Scaled Nonmonotone Memoryless BFGS Methods Devised Based on the Ellipsoid Vector Norm

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT We suggest a modified version of the nonnegative matrix factorization problem, adding penalty terms to the model with the aim of taking control of the condition number of the decomposition elements. This measure is taken to reinforce computational stability in the solution path of the relevant optimization model.

Unlocking Probiotic Potential: Physicochemical Approaches to Evaluate Probiotic Bacterial Adhesion Potential to the Intestinal Tract

open access: yesMolecular Nutrition &Food Research, EarlyView.
From the oral cavity to the establishment of bacterial adhesion in the intestinal tract, probiotic cells traverse 4 main stages: (1) bacterial transport, (2) reversible adhesion, (3) irreversible adhesion, and (4) biofilm formation. Each stage involves distinct mechanisms that govern the adhesion potential of bacteria to the intestinal mucus, which ...

The tentacles of surveillance: Cephalopods and United States satellite intelligence

open access: yesJournal for the Anthropology of North America, EarlyView.
Abstract This article examines the symbol placed on a US spy satellite, National Reconnaissance Office Launch–39 (NROL‐39). In 2013, NROL‐39 was launched into space, the payload vehicle and mission patch emblazoned with a gigantic octopus, its tentacles surrounding the globe, and the words “Nothing Is Beyond Our Reach” written below the globe.

Inspection Game With Imperfect Detection Technology

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT In this article, we investigate a generalized two‐player inspection game between an attacker and a defender who allocates multiple resources across a critical system. Specifically, the attacker targets components of the system while the defender coordinates multiple inspection units to monitor disjoint subsets of components and detect attacks.
