EURASIP Journal on Advances in Signal Processing, 2007 We introduce a novel method for secure computation of biometric hash on dynamic hand signatures using BioPhasor mixing and 2N discretization. The use of BioPhasor as the mixing process provides a one-way transformation that precludes exact recovery of ...

Advanced Materials Technologies, EarlyView.Nano‐TiO2 and carboxylated cellulose nanofibers jointly regulate hydration‐product distribution in cementitious composites. Improved microstructural continuity and refined pore structure accompany enhanced strength and surface stability without a substantial increase in overall hydration.

Time Series Decomposition Using Wavelet and Fourier Transforms for Enhanced Solar Flare Forecasting
Proceedings of the International Florida Artificial Intelligence Research Society ConferenceTime series decomposition enables the extraction of meaningful components by filtering out irrelevant or noisy frequencies. This study investigates the use of four transformation techniques—three wavelet-based (Haar, Symlets, Daubechies) and one Fourier-

Red‐Light Tomographic Volumetric 3D Printing in Seconds for Fabrication of Colorless Structures
Advanced Materials Technologies, EarlyView.A custom red‐light‐responsive TVAM platform combines methylene blue, triethanolamine, and PEGDA to fabricate transparent crosslinked hydrogels. Light patterns are projected into a rotating resin container, where a sacrificial photoinitiator system enables rapid polymerization and colorless channel‐containing structures, utilizing low‐energy light for ...

Advanced Materials Technologies, EarlyView.A THz metasurface device integrating a metal–dielectric–metal resonator with microwall‐defined recessed regions enables spatially guided, label‐free sensing of micrometer‐scale plastic particles. The as‐fabricated devices exhibit distinct THz reflection resonances for 3.1‐µm polystyrene particles and a concentration‐dependent resonance‐frequency‐shift ...

Basis‐Independent Geometric Phase Modulation in Circularly Birefringent Plasmonic Structures
Advanced Optical Materials, EarlyView.Here we introduce a plasmonic metasurface composed of spatially rotated chiral spiral unit cells designed to produce space‐variant circular retardance. This generates a geometric phase ramp equivalent to a blazed grating, leading to polarization dependent diffraction orders in momentum space.
