DeCoTa: a lightweight decentralized cross-chain transfer scheme based on hash-locking

Scientific Reports
With the wide application of blockchain comes the challenge of cross-chain interaction. For example, the isolation between the information stored in different blockchains can result in the ”isolated islands of value” effect in blockchains.

Yoda1‐Functionalized Nanozymes Coordinate Piezo1 Activation and Mitochondrial Protection to Reprogram the Diabetic Osteoimmune Micromilieu and Promote Vascularized Bone Repair

Advanced Science, EarlyView.
Diabetic bone defects remain a critical clinical challenge. A 3D‐printed BCPG‐MF@Y scaffold, embedding Yoda1‐functionalized manganese dioxide‐ferritin nanozymes, scavenges mtROS, suppresses the cGAS–STING pathway, and reverses cellular senescence, while Yoda1 activates Piezo1 to direct BMSCs fate to synergistically reprogram the osteoimmune ...

Integrated Model of Image Protection Techniques

Journal of Imaging, 2017
We propose an integrated model of Block-Permutation-Based Encryption (BPBE) and Reversible Data Hiding (RDH). The BPBE scheme involves four processes for encryption, namely block scrambling, block-rotation/inversion, negative-positive transformation and ...

Hardware‐Native Gaussian Sampling With Probabilistic Ising Machines for Modern Communication Paradigms

Advanced Science, EarlyView.
Probabilistic Ising machines are introduced as hardware‐native Gaussian samplers for edge communication workloads. Tunable variance and sampling density enable accurate distributions for Falcon‐class post‐quantum signatures and diffusion‐based semantic communication.

Atomic and privacy-preserving cyclic cross-chain protocol based on chameleon hash function

Blockchain: Research and Applications
Blockchain-based digital assets have increasingly emerged in recent years, necessitating cross-chain swaps. Hash Time-Lock Contract (HTLC) is a widely used protocol for such swaps; however, simple hash time locks can allow attackers to analyze ...

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 ...

Objectives and Key Results–Driven Multiagent Framework for Mechanical Design and Simulation

Advanced Intelligent Systems, EarlyView.
Objectives and key results (OKR)‐agent, an OKR‐driven multiagent framework, turns a plain‐language engineering goal into completed mechanical simulations. Three peer agents—supervisor, modeler, and simulator—share a compact board of OKR and coordinate external molecular dynamics (MD) and finite‐element solvers through a standardized tool interface. The

Blockchain Technology and the Circular Economy Transition: Associations With Company Performance

Business Strategy and the Environment, EarlyView.
ABSTRACT The adoption of circular economy (CE) practices in the private sector has received increasing academic and managerial attention, although the implementation of such practices continues to face significant barriers. Among Industry 4.0 technologies, blockchain has been identified as a potential factor associated with the CE transition.

Towards distributed hash tables (De)composition in ambient networks [PDF]

, 2006
When different wireless networks come in close proximity there is often a need for them to logically combine, or compose. We focus on a known research problem particularly in Ambient Networks (ANs), where heterogeneous Distributed Hash Tables (DHTs ...

Hyperledger Fabric for the (digitalized) lifecycle of construction products: Applied review on fastening technology

Civil Engineering Design, Volume 7, Issue 1, Page 9-22, March 2025.
Abstract Blockchain technology is a digital decentralized data ledger recording transactions in an encrypted format. Its implementation can potentially hold significant advantages for the built environment, particularly in manufacturing and building product usage aligned with Building Information Modeling (BIM). This paradigm shift toward decentralized
