Digital signatures over hash-entangled chains [PDF]
SN Applied Sciences, 2019 In this work we introduce a new approach for digital signature based on hash chains. The method is supported on the well known security principles of hash functions. Some main advantages of this public key system include security and estimated efficiency through the so called signature chains.

Advanced Science, EarlyView.Pulmonary hypertension (PH) is a progressive condition with high morbidity and mortality, largely owing to right ventricular (RV) failure resulting from maladaptive remodeling. Our study provides strong evidence in support of a critical, detrimental role for AXL as a previously unrecognized determinant driving RV fibrotic pathology in PH.

Advanced Science, EarlyView.NAD⁺ homeostasis maintains neuronal integrity through opposing actions of NMNAT2 and SARM1. Loss of NMNAT2 in glutamatergic neurons reprograms cortical metabolism from glucose to lipid catabolism, depletes lipid stores, and triggers inflammation and neurodegeneration.

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.

Digital signatures over HMAC entangled chains
Engineering Science and Technology, an International Journal, 2022 In this work we present a new digital signature method based on hash chains and the hash message authentication code (HMAC). Unlike Blockchain technology, our approach establishes that the database of transactions is distributed among users, so each one ...

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 .

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,
