Synthesis of N-Heterocyclic Carbene Gold Complexes Using 2,4,6-Trimethylphenyl Sydnone as Model Substrate

open access: yesChemistry Proceedings, 2022
Two gold(I) complexes have been synthesized by a two-step reaction. The first reaction step was the deprotonation with butyllithium to obtain the corresponding NHC.

F–multipliers and the localization of LMn×m–algebras

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2013
In this note, we introduce the notion of n × m-ideal on n × m- valued Łukasiewicz-Moisil algebras (or LMn×m-algebras) which allows us to consider a topology on them.

On-line carbon dots synthesis using flow injection analysis. Application to aluminium determination in water samples

open access: yesTalanta Open, 2023
An on-line synthesis of CDots is proposed for the first time, using the flow injection analysis (FIA) technique, which was coupled, in a single system, to the analytical determination of aluminium in water samples.

Efficiency and Technology Gap in European Apple Production—A Metafrontier Model for Germany, Italy, and Poland

open access: yesAgribusiness, EarlyView.
ABSTRACT EU member states have exhibited varying rates of apple production growth. Technical efficiency (TE) estimation is suitable for identifying best‐practice farm performance. This study examined whether the development of the apple sector in Germany, Italy, and Poland was influenced by production efficiency, access to technology, as well as ...

Dosing Interval Extension of Dupilumab in CRSwNP: Five‐Year Real World Outcomes

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis with nasal polyps (CRSwNP) is a persistent, often Type 2‐mediated inflammatory disease that markedly impairs quality of life. While dupilumab provides rapid improvement, there is limited evidence on long‐term outcomes beyond 2 years, and the clinical impact of dosing‐interval extension remains unclear.

Prospecting of Architectural Features Using LiDAR‐UAV Technology, Deep Neural Networks and Visualization Techniques: A Case Study in Kuélap and Cambolín (NW Peru)

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT High‐resolution and accurate synoptic images of terrestrial topography, even in densely forested areas, have proven valuable for archaeology by enabling the identification and characterization of relief patterns associated with ancient human activities. This study presents a novel approach that integrates digital terrain models (DTMs) obtained

Unconditionally Stable Algorithm for Copolymer and Copolymer-Solvent Systems

open access: yesPapers in Physics, 2020
In the time evolution simulation of a copolymer system towards its equilibrium configuration, it is common to use the Otha-Kawasaki approach for free energy and time evolution by means of a Cahn-Hilliard diffusion equation.
