Abelian and non-Abelian gauge theories are of central importance in many areas of physics. In condensed matter physics, Abelian U(1) lattice gauge theories arise in the description of certain quantum spin liquids. In quantum information theory, Kitaev's toric code is a Z(2) lattice gauge theory. In particle physics, Quantum Chromodynamics (QCD), the non-Abelian SU(3) gauge theory of the strong interactions between quarks and gluons, is non-perturbatively regularized on a lattice. Quantum link models extend the concept of lattice gauge theories beyond the Wilson formulation, and are well suited...

Non-structural carbohydrates are primary compounds whose distribution in the wood affects its properties. During the two last decades, a high variability of natural durability of plantation teak wood properties has been found with consequences for industry and consumers. In order to further investigate chemical traits for natural durability in Malaysian teak, we studied the radial distribution of main non-structural carbohydrates (NSC) from the sapwood to the inner heartwood. NSC were analysed by thin layer chromatography coupled to an enzymatic method. The main NSC were starch, glucose, fruct...

Near infrared (NIR) spectroscopy provides rapid and non-destructive analysis of wood properties and composition. In this study, we aimed to use NIR measurement for the prediction of teak phenolic compounds, which are chemical markers for natural durability of wood. Twenty-seven teak trees from two geographical zones (Malaysia and Ivory Coast) were used. On ground heartwood samples, the content of total phenolics and individual quinones (tectoquinone, 2-(hydroxymethyl)anthraquinone, 2-anthraquinone carboxylic acid, 1,4-naphthoquinone and 4′,5′-dihydroxy-epiisocatalponol) were determined using h...

AbstractThe problem addressed in this article is to reconfigure a set of unicast connections from an initial routing to a new precomputed routing while limiting the disruption induced for the clients. The goal is to plan reconfiguration order of connections without the interrupting flow. This problem is difficult to resolve because of the dependencies between the initial routing and the new routing. Existing works propose reconfiguration solutions that use backup path resources to temporarily move some connections. The final routing is found as you go. In this work, we reconfigure the initial...

Detecting redundant nodes and scheduling their activity is mandatory to prolong the lifetime of a densely-deployed wireless sensor network. Provided that the redundancy check and the scheduling phases both help to preserve the coverage ratio and guarantee energy efficiency. However, most of the solutions usually proposed in the literature, tend to allocate a large number of unnecessary neighbor (re)discovery time slots in the dutycycle of the active nodes. Such a shortcoming is detrimental to battery power conservation. In this paper, we propose a crossing points-based heuristic to fast detect...

AbstractThe ~ 1.5 Moz Yaouré gold deposit, which is located within the Birimian greenstone belts of central Côte d’Ivoire (West Africa), is associated with two stages of economic gold mineralization. Both ore-forming stages occurred during protracted E-W-directed shortening associated with the Eburnean orogeny. The first mineralization stage is hosted by fault-fill veins along conjugate ENE-striking (dextral) and WNW-striking (sinistral) strike-slip fault arrays. This ore stage is associated with a polymetallic assemblage including Mo, Bi, Pb, W, Te, Ag, and Au and cryptic alteration in wall r...

Corbula trigona shell powder (CTSP) was modified by a hydrothermal method using phosphoric acid to remove fluoride ions from groundwater. This method was performed by keeping the Ca/P molar ratio constant at 1.67. Fourier Transform Infrared Spectroscopy (FT-IR), X-Ray Diffraction (XRD) and scanning electronic microscopy (SEM) analysis confirmed the formation of hydroxyapatite (HAP) after CTSP pre-treatment. Batch adsorption experiments were conducted in beakers containing modified-CTSP. Moreover, the modified-CTSP dose variated from 0.1 to 0.8 g, in the presence of 100 mL of groundwater. This...

Resilience and empowerment are widely employed concepts in community psychology and other social sciences. Although empowerment is more closely associated with community psychology, both concepts hone to community psychology's strengths-based values, recognizing, respecting, and promoting local capacity and positive outcomes. Both concepts also have been critiqued for lacking clear consensus regarding definition, operationalization, and measurement (Cattaneo and Chapman in Am Psychol 65(7):646-659, 2010; Luthar et al. in Child Dev 71(3):543-562, 2000).

Watson) is one of the most problematic weeds in many cropping systems in the midsouthern United States because of its multiple weedy traits and its propensity to evolve resistance to many herbicides with different mechanisms of action. In Arkansas, A. palmeri has evolved metabolic resistance to S -metolachlor, compromising the effectiveness of an important weed management tool. Greenhouse studies were conducted to evaluate the differential response of A. palmeri accessions from three states (Arkansas, Mississippi, and Tennessee) to (1) assess th...

Abstract Tiafenacil is a new nonselective protoporphyrinogen IX oxidase (PPO)–inhibiting herbicide with both grass and broadleaf activity labeled for preplant application to corn, cotton, soybean, and wheat. Early-season corn emergence and growth often coincides in the mid-South with preplant herbicide application in cotton and soybean, thereby increasing opportunity for off-target herbicide movement from adjacent fields. Field studies were conducted in 2022 to identify the impacts of reduced rates of tiafenacil (12.5% to 0.4% of the lowest labeled application rate of 24.64 g ai ha –1 ) applie...

AbstractAccurate identification of soil bacteria that form nitrogen-fixing associations with legume crops is challenging given the phylogenetic diversity of root nodule bacteria (RNB). The labor-intensive and time-consuming 16S ribosomal RNA (rRNA) sequencing and/or multilocus sequence analysis (MLSA) of conserved genes so far remain the favored molecular tools to characterize symbiotic bacteria. With the development of mass spectrometry (MS) as an alternative method to rapidly identify bacterial isolates, we recently showed that matrix-assisted laser desorption ionization (MALDI) time-of-flig...

ABSTRACT: In Côte d’Ivoire, agricultural development has been made possible by the Government strategy to support it through an industrialization-based policy. However, the agricultural sector is still facing many difficulties, despite significant investment efforts undertaken to turn the country into a significant agricultural and agro-food industry (AFI) products exporter on the international market. This study evaluated the effectiveness of the driving role of AFI branches in the Ivorian economy. We used Leontief’s model, coupled with Diamond’s model and Rasmussen’s indices, to assess the r...
