Spiro‐Configured Self‐Assembling Molecule Modulates Phase Distribution at the Buried Interface for Efficient Sky‐Blue Perovskite LEDs

ABSTRACT Quasi‑two‑dimensional (quasi‑2D) perovskites are promising candidates for efficient blue perovskite light‑emitting diodes (PeLEDs), but their complex low‑dimensional phase distributions often result in non‑radiative recombination and emission broadening. Herein, we desig...

A Hardware-Enforced Human-Authorization Gate for Autonomous Launch Systems: An EHOX Use-Case Analysis of FAA 14 CFR Part 450

This engineering preprint analyzes how a hardware-enforced human-authorization gate could be evaluated at safety-critical decision points in autonomous launch and re-entry systems. It uses 14 CFR §450.107 as the regulatory anchor for phase-specific hazard-control strategies, func...

HEPE Lyapunov V(s)=0: First Hardware-Enforced AI Governance Certificate with Topological Bypass Impossibility

We introduce the HEPE (Hardware-Emergent Policy Enforcement) Lyapunov certificate V(s), a scalar function over the 16-state hardware governance space {0,1}^4 that provably reaches zero exactly when all four hardware enforcement layers are simultaneously active. We prove that V(s)...

EHOX AI Governance Certificate (AGC) Format Specification v1.0

Specification of the EHOX AI Governance Certificate (AGC) format v1.0. An AGC is a hardware-attested JSON document certifying that a specific AI action has been evaluated by a physically isolated ARM Cortex-R5F bare-metal policy engine (AMD Kria KV260) and approved according to 3...

Post-translational modifications in metabolic reprogramming: implications for metabolic therapy and immunotherapy in cancer

Cancer metabolism is characterized by profound reprogramming, yet the mechanisms enabling rapid and precise adaptation remain incompletely understood. This review establishes post-translational modifications (PTMs) as the central processing unit of oncogenic metabolic reprogrammi...
