Turnout and Invalid Voting in Brazilian Municipal Elections: A Runoff Voting System Tale

open access: yesScottish Journal of Political Economy, EarlyView.
ABSTRACT This paper assesses the impact of Brazil's hybrid mayoral voting system on voters' choices and examines the shift in blank, null, and turnout between the first and second rounds. Using fixed‐effects and RDD techniques over 5570 municipalities between 2000 and 2020, this study shows that runoff voting generates more abstention and invalid ...

Resistance training tempo selectively modulates corticospinal and reticulospinal excitability in humans

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Three weeks of unilateral resistance training (RT) performed under metronome‐paced (MP‐RT) or self‐paced (SP‐RT) conditions increased strength (maximum voluntary force (MVF) and one‐repetition maximum (1RM)) but were accompanied by distinct neural adaptations.

Language machines: Toward a linguistic anthropology of large language models

open access: yesJournal of Linguistic Anthropology, Volume 36, Issue 1, May 2026.
Abstract Large language models (LLMs) challenge long‐standing assumptions in linguistics and linguistic anthropology by generating human‐like language without relying on rule‐based structures. This introduction to the special issue Language Machines calls for renewed engagement with LLMs as socially embedded language technologies.

Improving Population Pharmacokinetic Modelling with Artificial Patients using Generative Artificial Intelligence

open access: yesPharmacology Research &Perspectives, Volume 14, Issue 2, April 2026.
ABSTRACT In population pharmacokinetics (PopPK), non‐linear mixed effects (NLME) models are used to simultaneously describe a drug's pharmacokinetics (PK) and dynamics (PD) in a patient population using systems of ordinary differential equations. In this field, machine learning is mainly used for data preparation, hypothesis generation, predictive ...
