Accurate measurement of longitudinal paramagnetic relaxation enhancement through division after subtraction

Lingshen Meng · Xinyuan Lu · Chun Tang

Paramagnetic relaxation enhancement (PRE) provides valuable distance constraints with respect to unpaired electron for the structural and dynamic characterization of biomolecules. While transverse PRE (Γ 2) has been widely used, its quantitative interpretation is often confounded by chemical exchange and other factors....

A 2D microfluidic paper sensor for mercury speciation in fish based on the peroxidase-mimicking activity of l-cysteine-functionalized iron oxide nanoparticles

Alberto Abalde-Pujales · Nerea Villarino · Francisco Pena-Pereira · Vanesa Romero

A novel, field-deployable colorimetric assay based on a two-dimensional microfluidic paper-based analytical device (2D μPAD) was developed for on-site mercury speciation in fish samples. The device integrates l-Cysteine (L-Cys) functionalized iron oxide nanoparticles (Fe3O4@L-Cys NPs) that act as mercury-responsive nan...

Global well-posedness and numerical approximation of a coupled Darcy-convection-diffusion system with exponential nonlinearity

Sahil Kundu · Amiya Kumar Pani · Manoranjan Mishra

This paper investigates density driven flow in porous media, focusing on the roles of viscosity contrast, density contrast, and linear adsorption. In this setup, the fluid on top is heavier and more viscous than the fluid below. Under the effect of gravity, this system becomes unstable, and finger-like structures appea...

Biofeedback in musicians: A systematic review and meta-analysis of its effects on muscle activity, musculoskeletal health, and performance

Miriam I. Olsen · Fernando Castellar · Simon Barker · Bronwen J. Ackermann · y 1 más

Musicians are at high risk for playing-related musculoskeletal disorders (PRMD) and playing- or performance-related pain (PRP), which can severely interfere with their practice routine, rehearsals, and performance. Although biofeedback offers a promising approach to address these problems, it has not been widely implem...

Constrained sensing and reliable state estimation with shallow recurrent decoders on a TRIGA Mark II reactor

Stefano Riva · Carolina Introini · J. Nathan Kutz · Antonio Cammi

Shallow Recurrent Decoder networks are a novel data-driven methodology able to provide accurate state estimation in engineering systems, such as nuclear reactors. This deep learning architecture is a robust technique designed to map the temporal trajectories of a few sparse measures to the full state space, including u...

Exploring the transitional parameter space of blazars using gamma-ray and X-ray population diagnostics

Zahoor Malik · Sikandar Akbar · Zahir Shah · B. van Soelen

We investigate the $γ$-ray and X-ray population properties of changing-look blazars (CLBs) using sources from the Fourth \textit{Fermi} LAT Source Catalog Data Release 4 (4FGL-DR4) together with X-ray information from the Living \textit{Swift} XRT Point Source (LSXPS) catalog. The CLB sample is compared with large popu...

Pheochromocytoma as a manifestation of Neurofibromatosis type 1: Clinical presentation, diagnosis, and genetic analysis

Neus, Baena-Díez · Ruth, Cano-Corres · Elisabet, Castellanos · Josep Leon, Mengibar · y 1 más

Neurofibromatosis type 1 (NF1) is a genetic multisystem disorder characterized by café-au-lait macules, neurofibromas, and other clinical features. Patients with NF1 have an increased risk of developing various tumours, including pheochromocytomas and paragangliomas (PPGLs), rare neuroendocrine tumours that secrete cat...

Analysis of a Cahn–Hilliard model for viscoelastoplastic two-phase flows

Cheng, Fan · Lasarzik, Robert · Thomas, Marita

We study a Cahn–Hilliard two-phase model describing the flow of two viscoelastoplastic fluids, which arises in geodynamics. A phase-field variable indicates the proportional distribution of the two fluids in the mixture. The motion of the incompressible mixture is described in terms of the volume-averaged velocity. Bes...

An integrated workflow for combined organic and inorganic chemical exposome analysis

S. Braeuer · M.L. Feuerstein · T. Buerki-Thurnherr · B. Warth · y 1 más

Humans are exposed to a multitude of non-genetic factors throughout their lives, all of which are encompassed in the concept of the exposome. To assess its chemical component, combinations of complementary analytical techniques are needed for broad chemical space coverage. However, approaches for combined organic and i...
