Nanoscale Confinement Enhances Ultrafast Demagnetization

open access: yesAdvanced Science, Volume 13, Issue 61, 3 November 2026.
Next generation spintronics may depend on successfully combining femtosecond spin dynamics with nanoscale device miniaturization. We address this by systematically studying the effect of nanoscale confinement on the femtosecond demagnetization of Iron. By combining ultrafast experiments sensitive to spins, charge carriers, and phonons, we uncover a nm ...

Unified Degenerate Central Bell Polynomials

open access: yes, 2019
In this paper, we firstly consider extended degenerate central factorial numbers of the second kind and provide some properties of them. We then introduce unified degenerate central Bell polynomials and numbers and investigate many relations and formulas including summation formula, explicit formula and derivative property.

Canonical Antibodies Adopt Distinct Binding Modes to Recognize Viral Glycan Shields

open access: yesAdvanced Science, Volume 13, Issue 61, 3 November 2026.
Canonical Y‐shaped antibodies recognize viral glycan shields through adaptive Fab assembly states shaped by glycan organization and somatic hypermutation. Structural analyses ofbroadly neutralizing antibodies VRC35 and VRC36 across glycoproteins of HIV‐1, influenza, SARS‐CoV‐2, and Lassa viruses reveal distinct Fab assembly states, spanning monovalent,

On the construction and structural analysis of Bell-enriched Appell-lambda polynomials via quasi-monomiality

open access: yesJournal of Nigerian Society of Physical Sciences
A fresh class of hybrid special polynomials, termed the Bell-enriched Appell-lambda-polynomials, is constructed through the discrete convolution of Bell-based lambda-polynomials with the Appell sequence.

Comparison of Amplitude‐ and Amplitude‐Frequency‐Modulated Pulses for Outer Volume Suppression in Cardiac MRI: Application to Myocardial T2 Mapping

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 5, Page 2240-2252, November 2026.
ABSTRACT Purpose To evaluate single‐ and dual‐band pulse modules for suppressing extra‐cardiac signal in cardiac MRI, and test their applicability for time‐efficient imaging with reduced FOV in myocardial T2 mapping at 3 T. Methods Outer Volume Suppression (OVS) was implemented using two regional saturation slabs, along the phase‐encoding direction ...

The Impact of BOLD‐Induced Linewidth Modulation on Functional 1H MRS Analysis

open access: yesNMR in Biomedicine, Volume 39, Issue 11, November 2026.
Functional MRS studies face a technical challenge: BOLD‐related lineshape changes can be mistaken for genuine metabolic changes, causing ~1% glutamate estimation bias at 3 and 7 T across conventional (LCModel, ABfit‐reg) and 2D fitting methods. Using synthetic data, this study shows that explicit BOLD linewidth correction—via dynamic lineshape ...

Spivey’s type recurrence relation for Lah-Bell polynomials

open access: yesMathematical and Computer Modelling of Dynamical Systems
The aim of this paper is to derive Spivey’s type recurrence relations for the Lah-Bell polynomials and the [Formula: see text]-Lah-Bell polynomials by utilizing operators [Formula: see text] and [Formula: see text] satisfying the commutation relation ...

Growth trajectory and miscarriage diagnosis threshold in early IVF pregnancy: multicenter study

open access: yesUltrasound in Obstetrics &Gynecology, Volume 68, Issue 5, Page 694-700, November 2026.
ABSTRACT Objectives To characterize early‐pregnancy ultrasound findings in pregnancies conceived via in‐vitro fertilization (IVF) for which gestational age is known precisely based on the date of embryo transfer (ET), and to examine their association with first‐trimester pregnancy outcome.

Behavioral Factors in Tax Preparer and Tax Compliance Choices

open access: yesKyklos, Volume 79, Issue 4, Page 862-878, November 2026.
ABSTRACT What tax preparer characteristics are most important to taxpayers in their decision to use a tax preparer, and how does this choice of a tax preparer affect subsequent taxpayer compliance? We use laboratory experiments to examine these questions. We find that individuals in this environment simultaneously choose a preparer and their compliance

Measuring Dry Deposition of Sea Spray Aerosol and Height of Aerosol Plume Using a Controlled Wave Pool

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Deposition of sea spray aerosols facilitates atmospheric corrosion of materials, requiring maintenance and replacement over time. However, the dimensions of sea spray aerosol plumes produced from breaking waves have not been well‐characterized, limiting useful prediction of particle transport downwind and atmospheric corrosion. Therefore, this
