Optimal synthesis of wideband shaped-beam array antenna through convex optimization
A linear-programming (LP) framework is introduced for the synthesis of wideband shaped-beam patterns produced by uniform linear arrays (ULAs). The single-frequency feasibility-based LP formulation is extended to a multi-frequency power mask by sampling the normalized spatial freq...

Dual‐Responsive Bidirectional Actuator for Biofilm Disruption on Medical Surfaces
Biofilms, dense microbial communities embedded in extracellular polymeric substances, present persistent challenges in medical devices by conferring antibiotic resistance and fostering chronic infections. Conventional antimicrobial or enzymatic approaches often fail due to poor p...

Thermodynamic Control of Excitation Transport Regimes in Nanocrystal Solids
Abstract Controlling excitation transport is central to the operation of light-harvesting and light-emitting devices based on nanocrystal films. Exciton diffusion is typically described as hopping through a homogeneous medium; however, even highly monodisperse nanocrystal ensembl...

E8 Antipodal Coherence Threshold — Critical φ-Sync Limit at N=233 — E8 Intelligence Research
Building on the 180° antipodal inversion principle, we discover that diametrically opposed E8 root pairs achieve stable bidirectional information transfer only when their shell count exceeds N=233 — the 13th Fibonacci number. Below this threshold, antipodal resonance collapses in...
