Comparison of Orthogonal Transforms for OFDM Communication System
Classical orthogonal frequency division (OFDM) employs fast Fourier transform (FFT) for elimination of inter-symbol interference (ISI) and expansion of time support of the transmitted signals.

We present a novel proteolysis‐targeting chimera (PROTAC) system conjugated to lipoic acid gold nanoclusters (PLANC), designed to degrade pTau, regulate inflammatory signaling, and effectively traverse the blood‐brain barrier (BBB). PLANC degraded pTau at various phosphorylation sites, with mechanistic studies confirming proteasome‐mediated degradation

Low‐Profile, High‐Gain GRIN RF Lenses via Multi‐Material Vat Photopolymerization
We investigate the opportunity of leveraging multi‐material vat photopolymerization printing to manufacture intricate lenses exhibiting permittivity gradients that can increase signal gain in transmitted radiofrequency signals in the X‐ and Ku‐bands. Lenses produced with more distinct low‐loss materials (up to 5) can deliver an 18 dB signal gain with a

Discrete Ridgelet Transforms for Image Representation
The ridgelet transform (Candes and Donoho, 1999) was introduced as a new multiscale representation for functions on continuous spaces that are smooth away from discontinuities along lines.

Co‐delivery of electrosprayed EDOT and oxidant enables bulk oxidative polymerization during layer‐by‐layer fabrication, creating stable, highly conductive 3D PEDOT structures. This Atomized Oxidative Polymerization (AOP) overcomes the surface deposition‐only and matrix‐limited conductivity of conventional Vapor Phase Polymerization (VPP) and PEDOT:PSS ...
