A Framework for Blockchain Interoperability and Runtime Selection
, 2019 The suitability of a particular blockchain for a given use case depends mainly on the blockchain's functional and non-functional properties. Such properties may vary over time, and thus, a selected blockchain may become unsuitable for a given use case ...

An Economic Analysis of Difficulty Adjustment Algorithms in Proof‐of‐Work Blockchain Systems
International Economic Review, EarlyView.ABSTRACT We study the stability of cryptocurrency systems through difficulty adjustment. Bitcoin's difficulty adjustment algorithm (DAA) exhibits instability when the reward elasticity of the hash rate is high, implying that a sharp price reduction could disrupt the current Bitcoin system.

Expected Length of the Longest Chain in Linear Hashing
, 2018 Hash table with chaining is a data structure that chains objects with identical hash values together with an entry or a memory address. It works by calculating a hash value from an input then placing the input in the hash table entry. When we place two inputs in the same entry, they chain together in a linear linked list.

Intentionality and Attentionality Dynamics in an Institutional Change Process
Journal of Management Studies, EarlyView.Abstract In this article, we explore how actors' intentionality emerges, develops, and co‐evolves with institutional change. Although intentions are essential in shaping institutional change agents' motivations and actions, our understanding of their dynamics is limited and biased by the assumption that intentions are usually identifiable prior to ...

Regulation &Governance, EarlyView.ABSTRACT We perform bibliometric analysis on documents for 255 Regulatory Impact Analyzes (RIAs) prepared by the US Environmental Protection Agency (EPA) from 1980 through 2024. Using a series of automated information extraction methods, we extract references from these documents and match them to bibliographic records.

A Chain Key Model Based on Message Hash Chain
To address the issue of key lifespan in key security, a chain key model based on a message hash chain is proposed. This model breaks away from the traditional scheme of generating random keys using random number generators, using plaintext features as a source of randomness, and generates the next key in conjunction with the current key, achieving key ...

Functional Graphs and Their Applications in Generic Attacks on Iterated Hash Constructions
IACR Transactions on Symmetric Cryptology, 2018 We provide a survey about generic attacks on cryptographic hash constructions including hash-based message authentication codes and hash combiners. We look into attacks involving iteratively evaluating identical mappings many times.

Challenges and opportunities in mitigating sarcoptic mange in wild South American camelids
The Journal of Wildlife Management, Volume 90, Issue 1, January 2026.Wild South American camelids—vicuña and guanaco—face threats from sarcoptic mange, a contagious skin disease linked to severe population declines. Despite its impact, major gaps remain in understanding disease dynamics. This review summarizes current knowledge, identifies key data and management gaps, and outlines urgent actions for effective ...
