Fluid ingress and surface wettability of 3D‐printed closed‐hollow obturator specimens across material types and printing orientations

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the effects of material type, printing orientation, and thermocycling on cumulative fluid ingress in three‐dimensional (3D)‐printed closed‐hollow obturator specimens and to compare water contact angle among material–printing orientation groups.

Design and optimisation of rapid real‐time PCR assays for the detection of key Culicoides species

Medical and Veterinary Entomology, EarlyView.
Species‐specific real‐time PCR assays were designed and optimised using primer/probe sets targeting C. obsoletus, C. scoticus, C. chiopterus, C. dewulfi, C. pulicaris, C. punctatus and C. impunctatus. Primer specificity and amplification efficiency were validated through in silico specificity analysis and real‐time PCR amplification profiling.

Hilbert Transform Pairs of Wavelets

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT The orthogonal projection of a real orthonormal wavelet basis onto the Hardy space—consisting of functions whose Fourier transform is supported only on the positive real axis—yields a Parseval frame of wavelets. Motivated by practical considerations, Kingsbury proposed the use of two real scaling functions from multiresolution analyses (MRAs ...

A Multimodal Deep Learning Based Framework for Early and Accurate Diagnosis of Depression Using Electroencephalography and Event‐Related Potential Signals

Applied AI Letters, Volume 7, Issue 3, October 2026.
Cross Wavelet Transform (XWT) is combined with a pre‐trained AlexNet to extract rich time‐frequency features from non‐stationary EEG signals. Also, the proposed framework simultaneously extracts and integrates spatial (Node2vec), time‐frequency (XWT + AlexNet), and spectral (PSD + TSCN) features from EEG and ERP signals within a parallel architecture ...

Design of Large‐Aperture Hybrid Refractive Metalens System

Nanophotonics, Volume 15, Issue 18, 25 September 2026.
An all‐germanium hybrid refractive–metalens system was constructed by integrating a planar Ge metalens with a single aspheric Ge lens, enabling compact wavefront correction in the LWIR band. The all‐Ge hybrid architecture simplifies conventional multi‐element infrared optics into a lightweight integrated imaging system while maintaining effective ...
