Maternal anorexia nervosa and risk of mental and neurodevelopmental morbidity in offspring

open access: yesChild and Adolescent Mental Health, EarlyView.
Background Anorexia nervosa has the potential to affect fetal neurodevelopment. We examined the association between maternal anorexia nervosa and mental, substance‐related, and neurodevelopmental morbidity in offspring. Methods We conducted a retrospective cohort study of 1,269,370 children in Quebec, Canada, between 2006 and 2022.

Effects of parachute science on local research capacity 降落伞科学对当地研究能力的影响

open access: yesConservation Biology, EarlyView.
Abstract Strengthening research capacity is essential to address the global biodiversity crisis. Yet, parachute science often undermines this goal, and its prevalence, costs, and benefits are unclear. We analyzed 13,502 publications on primate research that we extracted from Scopus (1960–2022) to evaluate the effects of parachute science on local ...

Bifurcation Analysis of a Stochastically Driven Limit Cycle [PDF]

open access: yes, 2018
We establish the existence of a bifurcation from an attractive random equilibrium to shear-induced chaos for a stochastically driven limit cycle, indicated by a change of sign of the first Lyapunov exponent.

Processes with Long Memory: Regenerative Construction and Perfect Simulation

open access: yes, 2000
We present a perfect simulation algorithm for stationary processes indexed by Z, with summable memory decay. Depending on the decay, we construct the process on finite or semi-infinite intervals, explicitly from an i.i.d. uniform sequence.
