Robotic Cell Micromanipulation Skill Learning via Imitation‐Enhanced Reinforcement Learning

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Humans can learn complex and dexterous manipulation tasks by observing videos, imitating and exploring. Multiple end‐effectors manipulation of free micron‐sized deformable cells is one of the challenging tasks in robotic micromanipulation. We propose an imitation‐enhanced reinforcement learning method inspired by the human learning process ...

Differences in Risk Factors for Severe Preeclampsia and HELLP Syndrome in Singleton Versus Twin Pregnancies: A Population‐Based Cohort Study

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Objective To examine whether the associations between pre‐pregnancy risk factors and severe preeclampsia/eclampsia (SPE) and/or HELLP syndrome differ between singleton and twin pregnancies. Design A population‐based retrospective cohort study. Setting British Columbia (BC), Canada.

Generalisability of Maternal Genetic Risk Score for Birth Weight Across Racial Identity and Ancestry: A Secondary Analysis of a Prospective Cohort Study

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Objective Maternal genotypes may be useful to customise foetal growth assessment, but generalisability across diverse racial and ancestral groups remains uncertain. We assessed the generalisability of a genetic risk score for birth weight (GRSBW), derived from participants of predominantly European ancestry, within a diverse U.S.

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.
