Reliability of three scoring systems for assessing quality of anaesthetic induction in horses
Equine Veterinary Journal, EarlyView.Abstract Background Several induction quality scoring systems (IQSS) have been described to evaluate drugs and risk factors of this anaesthetic period in horses, but no attempts to compare their reliability have been performed. Objectives To elucidate the reliability of three IQSS: the visual analogue scale (VAS), a simple descriptive scale (SDS), and ...

An iterated greedy‐based metaheuristic with local search for the rank pricing problem
International Transactions in Operational Research, EarlyView.Abstract The rank pricing problem involves determining optimal prices for a set of products while accounting for customers' budgets and preferences. This study develops an iterated greedy‐based metaheuristic to efficiently solve this problem. The core idea is to generate a sequence of solutions by iteratively applying destruction and reconstruction ...

New Phytologist, EarlyView.Summary Reflectance spectroscopy is a rapid method for estimating traits and discriminating species. Spectral libraries from herbarium specimens represent an untapped resource for generating broad phenomic datasets across space, time, and taxa. We conducted a proof‐of‐concept study using trait data and spectra from herbarium specimens up to 179 yr old,

Beyond species means – the intraspecific contribution to global wood density variation
New Phytologist, EarlyView.Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from
