Rapid and sensitive multi-residue method for the determination of 235 organic microcontaminants in environmental water samples using direct injection coupled to ultra-high performance liquid chromatography-tandem mass spectrometry

Eva Jambrina-Hernández · Patricia Plaza-Bolaños · Samira Nahim-Granados · Ana Agüera

A rapid and sensitive direct injection (DI) method is proposed for the monitoring of 235 organic microcontaminants (OMCs), including those listed in the recently adopted Directive (EU) 2024/3019 and the 5th Watch List, in treated wastewater (WW) and drinking water (DW), using ultra-high performance liquid chromatograph...

A decomposition method for solving sensitivity-based distributed optimal power flow

Mohannad Alkhraijah · Devon Sigler · Daniel K. Molzahn

Efficiently solving large-scale optimal power flow (OPF) problems is challenging due to the high dimensionality and interconnectivity of modern power systems. Decomposition methods offer a promising solution via partitioning large problems into smaller subproblems that can be solved in parallel, often with local inform...

Collaborating with GenAI: A blessing or a curse for creativity?

Sara Caprioli

Recent advances in generative artificial intelligence (GenAI) are increasingly shifting creative work from individual creation toward human-AI collaboration. Drawing on evidence from various creative domains, such as writing, design, and product ideation, this review highlights the gains and constraints of collaboratin...

Novel approach on phosphorus speciation during thermo chemical treatment of biogenic residues using electrothermal vaporization

Teres Pietschner · Thomas Vogt · Dina Friebel · Stefan Guhl · y 2 más

A quick, direct analysis of the phosphorus content and the chemical binding of phosphorus in sewage sludge is essential for thermal conversion processes like incineration, gasification, pyrolysis or thermal P recovery. While only the contents in the energy raw materials are usually decisive for energy use via incinerat...

Counting integral points in homogeneous spaces over function fields

Sheng Chen · Jing Liu

We establish the asymptotic formula for the number of integral points in non-compact symmetric homogeneous spaces of semi-simple simply connected algebraic groups over global function fields, given by the sum of the products of local densities twisted by suitable Brauer elements. As an application, we count the number...

Explicit hypergeometric modularity of certain weight two and four Hecke eigenforms

Maity, Sipra · Barman, Rupam

Recently, Allen \emph{et al.} developed the Explicit Hypergeometric Modularity Method (EHMM) that establishes the modularity of a large class of hypergeometric Galois representations in dimensions two and three. Motivated by this framework, we construct two explicit families of eta-quotients, which we call the $\mathbb...

Development and test-retest reliability of a laboratory-based shipboard firefighting simulation for controlled performance testing

Bronia Glen · Jodie A. Wills · Mark Wiggins · Rhiannon Campbell · y 3 más

Understanding shipboard firefighting performance is critical for improving crew safety and vessel preservation during damage control events. While prior research has been conducted in naval spaces, controlled simulations that assess performance without requiring naval vessels, personnel or specialised equipment are lac...

Quantifying locomotor instability in healthy adults: Insights from treadmill-induced slips and trips using a dynamic criterion

Lallès, Ariane · Pillet, Hélène · Le Mouel, Charlotte · Bonnet, Xavier · y 1 más

Background: Understanding how the musculoskeletal and nervous systems maintain balance during walking remains challenging. Instability is difficult to quantify in real-life settings and no fully developed wearable system is currently available to measure it outside the laboratory. Treadmills provide a safe, compact, st...

Magnetic eutectic mixture as extractant for elemental analysis of essential oils combining liquid-phase microextraction and inductively coupled plasma optical emission spectrometry

Kevin S. Marín-Henao · Sergio J. Abellán-Martín · Miguel Ángel Aguirre · Lorena Vidal · y 1 más

In the present work, a simple, fast, sensitive and accurate method was developed to determine Cd, Cr, Cu, Fe, Mn, Ni, Pb, V, and Zn in essential oil samples at trace levels by inductively coupled plasma optical emission spectrometry (ICP OES). Vortex-assisted dispersive liquid-liquid microextraction (VA-DLLME) was empl...
