The Evaluation of a Double-Spend Attack Probability for Ouroboros-like Proof-of-Stake Consensus

open access: yesJournal of Cybersecurity and Privacy
This paper studies the probability of a double-spend attack in an Ouroboros-like Proof-of-Stake (PoS) setting when confirmation decisions must be made for a finite number of blocks.

Neuron‐Targeted Exosomal Delivery of siRNA Against RIPK3 Slows Neurodegenerative Progression in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
Engineered exosomal siRNA delivery platform enables systemic, neuron‐targeted RNA transport across the blood–brain barrier. Surface functionalization with rabies virus glycoprotein‐derived peptide facilitates receptor‐mediated transcytosis, achieving efficient cytosolic delivery and robust gene silencing. Targeting RIPK3 suppresses necroptosis, reduces

Absorption of Broadband Low‐Frequency Sound Beyond the Thermodynamics Limit: An Acoustic Resonator With Magnetic Bearing

open access: yesAdvanced Science, EarlyView.
This work presents a magnetic‐bearing acoustic resonator that overcomes the thermodynamics limit of sound absorption. By introducing tunable negative stiffness, it achieves broadband low‐frequency absorption within a compact cavity, far exceeding the performance achievable by classic mass‐tuned designs.
