Markov Determinantal Point Process for Dynamic Random Sets

Journal of Time Series Analysis, Volume 47, Issue 4, Page 784-802, July 2026.
ABSTRACT The Law of Determinantal Point Process (LDPP) is a flexible parametric family of distributions over random sets defined on a finite state space, or equivalently over multivariate binary variables. The aim of this paper is to introduce Markov processes of random sets within the LDPP framework. We show that, when the pairwise distribution of two

Perpetual Futures Pricing

Mathematical Finance, Volume 36, Issue 3, Page 481-499, July 2026.
ABSTRACT Perpetual futures are contracts without expiration date in which the anchoring of the futures price to the spot price is ensured by periodic funding payments from long to short. We derive explicit expressions for the no‐arbitrage price of various perpetual contracts, including linear, inverse, and quantos futures in both discrete and ...

Security‐Enhanced Differential Binary‐Phase‐Shift‐Keying Quantum Key Distribution With a Wavelength‐Switchable Single‐Photon Carrier

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
A single‐chip dual‐wavelength coherent photon source is proposed to add parametric uncertainty and improve the security of single‐photon differential binary‐phase‐shift‐keying quantum key distribution. This wavelength‐uncertain coding or decoying operation enables flexible and secure D‐BPSK‐QKD transmission over a wavelength‐division‐multiplexed ...

“What Could Possibly Go Wrong?”: A Consumer‐Centric Approach to Exploring Vulnerability and Algorithmic Bias in AI‐Driven Financial Planning

FINANCIAL PLANNING REVIEW, Volume 9, Issue 2, June 2026.
ABSTRACT With the accessibility of generative AI, the uptake of consumers using it for their financial planning queries and needs has exponentially increased. However, algorithmic bias in AI‐driven financial planning poses significant challenges, particularly to consumers experiencing vulnerabilities as it can cause further marginalization by the ...

Blockchain technology disruptions: Exploring accounting and auditing academics and practitioners' perception

Accounting &Finance, Volume 66, Issue 2, Page 1972-1999, June 2026.
Abstract This study explores the practical impact of blockchain technology (BCT), which contrasts strongly with literature that has predominantly hypothesised BCT's potential to disrupt accounting practice. We interviewed 44 practitioners and academics with knowledge of BCT across 13 countries and industries.
