New Scheme of Empirical Likelihood Method for Ranked Set Sampling: Applications to Two One‐Sample Problems

open access: yesInternational Statistical Review, Volume 93, Issue 3, Page 459-498, December 2025.
Summary We propose a novel empirical likelihood (EL) approach for ranked set sampling (RSS) that leverages the ranking structure and information of the RSS. Our new proposal suggests constraining the sum of the within‐stratum probabilities of each rank stratum to 1/H, where H is the number of rank strata.

Taxonomy and nomenclature of Rubus ser. Glandulosi (Rosaceae) across its Eurasian range: Revised concepts and new approaches

open access: yesTAXON, Volume 74, Issue 5, Page 1106-1152, October 2025.
Abstract Rubus ser. Glandulosi is one of the most taxonomically intricate taxa of the genus, which is by itself considered a taxonomical nightmare.

Optimising the tumour elimination payoff in cancer therapy

open access: yesIET Control Theory &Applications, Volume 18, Issue 13, Page 1621-1637, September 2024.
Optimal therapies are derived that maximise the tumour elimination payoff (TEP), a payoff motivated from branching processes that balances the expected lifespan under therapy against drug toxicity. The TEP provides a post‐treatment outcome probability for cure and relapse.
