Museomics Deciphers the Phylogeographic Differentiation and Conservation Status of a Montane Pheasant

Integrative Zoology, EarlyView.
Museum specimens provide a rich source of historical DNA, enabling insights into phylogenetic relationships and demographic history of the endangered Koklass Pheasant. Our findings uncovered a previously unrecognized population in Guizhou province and highlighted elevated extinction risk in populations from Anhui province and Southern China, informing ...

Evaluating the optimal duration of medication treatment for opioid use disorder

Addiction, EarlyView.
Abstract Background and aims Clinicians have little guidance on the ideal length of time patients should remain on medication treatment for opioid use disorder (MOUD) before being able to safely discontinue MOUD. This study estimated how the risk of all‐cause mortality changes with the duration of MOUD, controlling for patient characteristics that ...

Identification and Estimation of Large Network Games with Private Link Information

International Economic Review, EarlyView.
ABSTRACT We study the identification and estimation of large network games in which individuals choose continuous actions while holding private information about their links and payoffs. Extending the framework of Galeotti et al., we build a tractable empirical model of such network games and show that the parameters in individual payoffs are ...

Medical Knowledge Integration Into Reinforcement Learning Algorithms for Dynamic Treatment Regimes

International Statistical Review, EarlyView.
Summary The goal of precision medicine is to provide individualised treatment at each stage of chronic diseases, a concept formalised by dynamic treatment regimes (DTR). These regimes adapt treatment strategies based on decision rules learned from clinical data to enhance therapeutic effectiveness.

A new species of Peckoltia (Siluriformes, Loricariidae) from the rapids of the Rio Tocantins‐Araguaia basin, Brazil

Journal of Fish Biology, EarlyView.
Abstract Here, we describe a new species of Peckoltia (Loricariidae; Hypostominae) from the rapids of the Rio Tocantins‐Araguaia basin, previously identified as Peckoltia vittata, using an integrative taxonomy approach. The new species is distinguished from congeners by ventral region presenting diffuse stripes on surface, not presenting spots or ...

Cluster Policy, Innovation, and Firm Productivity. An Econometric Assessment of the Flemish Spearhead Cluster Program

Journal of Regional Science, EarlyView.
ABSTRACT The Flemish government launched its Spearhead Cluster (SHC) policy in 2017. The aim is to boost strategic sectors by setting up cluster initiatives which coordinate collaborative R&D initiatives. In this paper, we analyze whether becoming a member of such a cluster initiative has an impact on the Total Factor Productivity (TFP) of the firm. We

Profiling the sleep architecture of ageing adults using a seven‐state continuous‐time Markov model

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Sleep is a complex biological process regulated by networks of neurons and environmental factors. As one falls asleep, neurotransmitters from sleep–wake regulating neurones work in synergy to control the switching of different sleep states throughout the night. As sleep disorders or underlying neuropathology can manifest as irregular switching,

A Conditional Tail Expectation Type Risk Measure for Time Series

Journal of Time Series Analysis, EarlyView.
ABSTRACT We consider the estimation of the conditional expectation 𝔼(Xh|X0>UX(1/p)), provided 𝔼|X0|<∞, at extreme levels, where (Xt)t∈ℤ$$ {\left({X}_t\right)}_{t\in \mathbb{Z}} $$ is a strictly stationary time series, UX$$ {U}_X $$ its tail quantile function, h$$ h $$ is a positive integer and p∈(0,1)$$ p\in \left(0,1\right) $$ is such that p→0$$ p\to ...

Measure‐valued processes for energy markets

Mathematical Finance, Volume 35, Issue 2, Page 520-566, April 2025.
Abstract We introduce a framework that allows to employ (non‐negative) measure‐valued processes for energy market modeling, in particular for electricity and gas futures. Interpreting the process' spatial structure as time to maturity, we show how the Heath–Jarrow–Morton approach can be translated to this framework, thus guaranteeing arbitrage free ...

Haplotype‐Resolved Genome Assembly and Population Genomics Reveal Evolutionary History and Agronomic Traits of Mulberry

Plant Biotechnology Journal, EarlyView.
ABSTRACT Mulberry is a representative economic tree species valued for both poverty alleviation and medicinal use. To advance the understanding of mulberry genomics and demography, we assembled high‐quality haploid genomes of two widely cultivated mulberry varieties NS14 and QS1, and analysed 376 accessions from 12 countries, including 39 ancient trees
