Active Learning‐Assisted Exploration of [PO40Mo12]3− for Alzheimer's Therapy Insights

Advanced Science, Volume 12, Issue 42, November 13, 2025.
Bayesian Optimization coupled with active learning to uncover the interaction mechanism of [PO40Mo12]3− on amyloid‐β peptide. Abstract Alzheimer's disease (AD), involving amyloid‐β (Aβ) aggregation, has potential therapeutic modulators in polyoxometalates (POMs) like [PMo12O40]3−.

On Approximations by Trigonometric Polynomials of Classes of Functions Defined by Moduli of Smoothness

Abstract and Applied Analysis, 2017
In this paper, we give a characterization of Nikol’skiĭ-Besov type classes of functions, given by integral representations of moduli of smoothness, in terms of series over the moduli of smoothness.

On some lacunary difference sequence spaces defined by a sequence of Orlicz functions and q-lacunary Δnm-statistical convergence

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012
In this article, we introduce the lacunary difference sequence spaces w0(M, θ, Δnm, p, q), w1(M, θ, Δnm, p, q) and w∞(M, θ, Δnm, p, q) using a sequence M = (Mk) of Orlicz functions and investigate some relevant properties of these spaces. Then, we define

An analytical representation of airfoils [PDF]

INCAS Bulletin
An important part of the construction of an aircraft is the shape of the wings. Their aerodynamics involve numerous evaluations and simulations through fluid dynamics. The reduction of the evaluation times is achieved by a parametric function.

Ferrimagnetic Structure of 3C Pyrrhotite (Fe7S8) From Neutron Diffraction

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract Pyrrhotite is a paleomagnetically important magnetic mineral in many geological settings. It forms numerous polytypes with different stacking patterns of the NiAs structure along the crystallographic c axis to produce different vacancy‐ordered superstructures.

Polyoxotungstate‐Stabilized Gold Nanoparticles: How to Transfer from an Aqueous Suspension to CH3CN

European Journal of Inorganic Chemistry, Volume 28, Issue 22, August 20, 2025.
Available methods inspired by the literature for preparing stable suspensions of gold nanoparticles stabilized by polyoxometalates (POMs@AuNPs) in CH3CN, a solvent commonly used in oxidation reactions, are compared. The evaluation criteria used are the ease of obtaining and the stability of the POM@AuNPs suspensions, as well as the reproducibility of ...

DFT Study of Halide‐Free Mechanism of the CO2 Cycloaddition onto Epoxide by [PW11O39{Zn(H2O)}]5−: Evidences for the Formation of Hydrogencarbonate Intermediates

ChemCatChem, Volume 17, Issue 15, August 7, 2025.
The computational study, sustained by experimental data, of the catalytic activity of [PW11O39{Zn(H2O)}]5− in CO2 cycloaddition to epoxide highlights how the carbonic anhydrase‐like character of this complex couples to the versatile binding properties of the polyoxometalate in this reaction pathway. Abstract The intertwined experimental and theoretical
