An Economic Analysis of Difficulty Adjustment Algorithms in Proof‐of‐Work Blockchain Systems

open access: yesInternational 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.

Can NSEC5 be practical for DNSSEC deployments? [PDF]

open access: yes, 2017
NSEC5 is proposed modification to DNSSEC that simultaneously guarantees two security properties: (1) privacy against offline zone enumeration, and (2) integrity of zone contents, even if an adversary compromises the authoritative nameserver responsible ...

Development, external validation and integration into clinical workflow of machine learning models to support pre‐operative assessment in the UK

open access: yesAnaesthesia, Volume 81, Issue 2, Page 201-212, February 2026.
Summary Introduction Demand for surgical treatment is growing and patient complexity is increasing. The NHS England standard contract now requires that pre‐operative services risk stratify and optimise patients awaiting surgery. However, current pre‐operative workflows (whether electronic or paper‐based) remain based primarily on resource‐intensive ...

Parallel Algorithm for Approximate State Graph Exploration With Restricted Memory Footprint

open access: yesConcurrency and Computation: Practice and Experience, Volume 38, Issue 1, January 2026.
ABSTRACT We investigate the performance of algorithms that explore large state graphs of finite state machines without input by following paths. To improve on anchor‐based and candidate‐based explorations and to avoid the performance overhead of full anchor lists and the tuning sensitivity of timeout‐based methods, we propose and analyze exploration ...

The Impact of Environmental Information on Cryptocurrency Investment Allocation Decisions: An Experimental Survey Study

open access: yesCorporate Social Responsibility and Environmental Management, Volume 33, Issue 1, Page 217-235, January 2026.
ABSTRACT Despite the universal acknowledgment of financial profit expectations as an investment driver, environmental concern has been suggested as a factor influencing investors' decisions to purchase cryptocurrency. In this sense, this study investigates the impact of environmental information on investment allocation decisions to purchase different ...
