The Generation and Control of Irregularly Shaped Perfect Vector Vortex Beams on Hybrid Poincaré Spheres Using All‐Dielectric Metasurfaces

Nanophotonics, Volume 15, Issue 3, 12 February 2026.
Based on an all‐dielectric metasurface with cross‐phase modulation, we achieve the generation and polarization control of integers and fractional order irregular perfect vector vortex beams on the hybrid Poincaré sphere, opening a new avenue for optical field manipulation.

Investigation on the Coherent Component of SHARAD Surface Echo and Surface Roughness: Scaling Behavior and Influence of Hurst Exponent

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract The radar surface echo can be separated into coherent and incoherent components by statistical approaches, and the coherent component can be described by a backscattering model related to the RMS height. According to backscattering models for fractal surfaces, the coherent power in decibels decreases with RMS height on a scale independent of ...

The Calcium‐Binding Protein S100A10 (p11) Is Required for Normal Motor Performance by Regulating Vesicle Dynamics at Excitatory Synapses

Acta Physiologica, Volume 242, Issue 2, February 2026.
ABSTRACT Aim Identifying interactors in sensorimotor processing and neurotransmission remains a current challenge for understanding neural information processing and brain function. Methods To evaluate the role of p11 in sensorimotor processing and excitatory synaptic neurotransmission, neuron‐specific lentivirus‐directed p11 silencing, small ...

Pólya's conjecture for Dirichlet eigenvalues of annuli

Journal of the London Mathematical Society, Volume 113, Issue 2, February 2026.
Abstract We prove Pólya's conjecture for the eigenvalues of the Dirichlet Laplacian on annular domains. Our approach builds upon and extends the methods we previously developed for disks and balls. It combines variational bounds, estimates of Bessel phase functions, refined lattice point counting techniques and a rigorous computer‐assisted analysis. As

Exploring Advanced Versions of Hermite-Hadamard and Trapezoid-Type Inequalities by Implementation of Fuzzy Interval-Valued Functions

Journal of Function Spaces
The extension of interval-valued and real-valued functions known as fuzzy interval-valued function (FIVF) has made substantial contributions to the theory of interval analysis.

Ambient‐Noise Multicomponent Multimodal Dispersion Characteristics in Thick Sedimentary Basins

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Ambient noise cross‐correlations enable the extraction of multimodal surface waves, yet resolving their complex dispersion characteristics is essential for robust subsurface imaging. Using dense array data from the North China Plain, we resolve multicomponent multimodal Rayleigh and Love wave dispersion with unprecedented detail.
