Statistically-secure ORAM with $\tilde{O}(\log^2 n)$ Overhead

, 2013
We demonstrate a simple, statistically secure, ORAM with computational overhead $\tilde{O}(\log^2 n)$; previous ORAM protocols achieve only computational security (under computational assumptions) or require $\tilde{\Omega}(\log^3 n)$ overheard.

Mechanism‐Driven Screening of Membrane‐Targeting and Pore‐Forming Antimicrobial Peptides

Advanced Science, EarlyView.
To combat antibiotic resistance, this study employs mechanism‐driven screening with machine learning to identify pore‐forming antimicrobial peptides from amphibian and human metaproteomes. Seven peptides are validated, showing minimal toxicity and membrane disruption.

Neuroprotective Effects of Time‐Restricted Feeding Combined With Different Protein Sources in MPTP‐Induced Parkinson's Disease Mice Model and Its Modulatory Impact on Gut Microbiota Metabolism

Advanced Science, EarlyView.
Time‐restricted feeding (TRF) exerts protein‐dependent neuroprotective effects in an MPTP‐induced Parkinson's disease model. In casein‐fed mice, TRF improves gut barrier integrity and reduces neuroinflammation, possibly via modulation of Allobaculum and BCAAs.

Deconstructing the Blockchain to Approach Physical Limits [PDF]

, 2018
Transaction throughput, confirmation latency and confirmation reliability are fundamental performance measures of any blockchain system in addition to its security. In a decentralized setting, these measures are limited by two underlying physical network

Machine Learning for Green Solvents: Assessment, Selection and Substitution

Advanced Science, EarlyView.
Environmental regulations have intensified demand for green solvents, but discovery is limited by Solvent Selection Guides (SSGs) that quantify solvent sustainability. Training a machine learning model on GlaxoSmithKline SSG, a database of sustainability metrics for 10,189 solvents, GreenSolventDB is developed. Integrated with Hansen solubility metrics,

Fast Verification of Hash Chains [PDF]

, 2004
A hash chain is a sequence of hash values x i = hash(x i − 1) for some initial secret value x 0. It allows to reveal the final value x n and to gradually disclose the pre-images x n − 1, x n − 2, ... whenever necessary. The correctness of a given value x i can then be verified by re-computing the chain and comparing the result to x n .

Security-Enhanced Decentralized Content Sharing in Publish/Subscribe System

IEEE Access
We consider a content dissemination model, where the contents disseminated from a content source on a regular or event-driven basis are shared among the group members, without directly contacting the content source.
