Interactions of curcumin-coated silver nanoparticles with sparsely tethered bilayer membranes containing an ion-gate-forming peptide

Marina, Serantoni · Felice Carlo, Simeone · Magda, Blosi · Anna Luisa, Costa

Understanding nanoparticle-membrane interactions is important for assessing nanotoxicity and drug delivery mechanisms. This work uses electrochemical analysis to investigate how curcumin-coated silver nanoparticles influence the biophysical properties of a gold-supported sparsely tethered Bilayer Lipid Membrane (stBLM)...

Counting biquadratic number fields with quaternionic and dihedral extensions

Louis M. Gaudet · Siman Wong

We establish asymptotic formulae for the number of biquadratic number fields of bounded discriminant that can be embedded into a quaternionic or a dihedral extension. To prove these results, we express the solvability of these inverse Galois problems in terms of Hilbert symbols, and then apply a method of Heath-Brown t...

A note on harmonic polynomials on Heisenberg and Carnot groups

Francesco Paolo Maiale

We study harmonic polynomial traces on Korányi spheres in the Heisenberg groups and polynomial trace filtrations on general Carnot groups. The homogeneous harmonic trace spaces are algebraically direct and complete on the Heisenberg sphere, but different homogeneous degrees are not generally orthogonal. In fact, on eve...

A mixed interpolation-regression method for numerical integration on the unit circle using zeros of para-orthogonal polynomials

Ruymán Cruz-Barroso · Lidia Fernández · Francisco Marcellán

A new alternative numerical procedure to the Szegő quadrature formulas for the estimation of integrals with respect to a positive Borel measure $μ$ supported on the unit circle is presented. As in many practical situations, we assume that the values of the integrand $F$ are only known at a finite number of points, whic...

Impaired immune response to polysaccharide antigensand warning signs in children with recurrent respiratoryinfections

Selene, Pury · Vanina, Marini · Natalia A, Lozano · Laura V, Sasia · y 6 más

Introduction. Inborn errors of immunity constitute a group of genetic disorders that may present with warning signs. Among their most common presentations are recurrent respiratory infections, which may reflect abnormalities in humoral immunity. In this context, specific antibody deficiency (SAD) is characterized by an...

Perceptions of expertise and its development among critical care trainees and staff physicians: A qualitative interview study

Ece, Üreten · Victoria, McCredie · Catherine M, Burns

In highly specialized fields such as critical care medicine (CCM), understanding how expertise is defined and developed is essential for both clinical practice and education. While expertise has been widely studied, its characteristics and developmental trajectory among critical care physicians remain incompletely unde...

UniFLM: United Segmentation and Measurement on Fetal Limb Ultrasonic Image

Zeen Zhou · Qiuhua Chen · Xiaojun Cao · Changmao Chen · y 2 más

Prenatal ultrasound examination is crucial for assessing fetal limb development and detecting congenital anomalies. However, existing artificial intelligence models often overlook fetal lethal skeletal dysplasias due to the lack of high-quality annotated data and a unified framework for multiple long bones. Moreover, g...

Geometric properties of unit groups of von Neumann's continuous rings

Friedrich Martin Schneider

We prove that, if $R$ is a non-discrete irreducible, continuous ring, then its unit group $\mathrm{GL}(R)$, equipped with the topology generated by the rank metric, is topologically simple modulo its center, path-connected, locally path-connected, bounded in the sense of Bourbaki, and not admitting any non-zero escape...

Examples and counterexamples of injective types

Tom de Jong · Martín Hötzel Escardó

It is known that, in univalent mathematics, type universes, the type of $n$-types in a universe, reflective subuniverses, and the underlying type of any algebra of the lifting monad are all (algebraically) injective. Here, we further show that the type of ordinals, the type of iterative (multi)sets, the underlying type...

High-accuracy ultrasonic positioning of calibration sources in the Jiangmen Underground Neutrino Observatory

Ziqian Xiang · Rongcheng Chen · Zhangmin Chen · Qian Cheng · y 19 más

Precise source positioning is essential for detector calibration in large liquid scintillator detectors such as JUNO, particularly in regions where purely mechanical control is insufficient. An ultrasonic positioning system has been developed to reconstruct the three-dimensional coordinates of a calibration source with...
