Navigating Gravity: Competing Effects Result in Opposing Taxis for Different Janus Swimmers

open access: yesSmall, EarlyView.
The combined effects of gravity and wall‐induced hydrodynamics on the motion of Janus colloids are investigated. Platinum‐ and copper‐coated silica microswimmers show distinct gravitactic alignment near surfaces due to different hydrodynamic couplings. This distinct gravitactic behavior enables separation of initially mixed active particles.

Extreme Weather Events and Agricultural Total Factor Productivity Growth

open access: yesSouthern Economic Journal, EarlyView.
ABSTRACT The productivity of the agricultural sector is crucial for food security in a changing climate. This study estimates the impacts of extreme weather events on agricultural total factor productivity (TFP) growth, contributing to a more comprehensive understanding of the effects of climate change on agriculture.

Ultrasound features in early pregnancy for predicting abnormal karyotype in first‐trimester miscarriage

open access: yesUltrasound in Obstetrics &Gynecology, EarlyView.
ABSTRACT Objective To investigate whether combining abnormal morphological features observed on ultrasound in live pregnancies that ended in a first‐trimester miscarriage can predict an abnormal karyotype. Methods This retrospective observational cohort study was conducted at the early‐pregnancy assessment unit at University College London Hospital ...

Home range and core area characteristics of urban and rural coyotes and red foxes in southern Wisconsin

open access: yesWildlife Biology, EarlyView.
Second‐order habitat selection is influenced by a variety of factors, including individual‐ and species‐specific traits and resource requirements, as well as landscape characteristics. By comparing home range characteristics across individuals, species, and landscapes, we can draw conclusions regarding whether and how different factors influence home ...

Beyond abundance: the impact of sampling design on effective population size estimates in capercaillie

open access: yesWildlife Biology, EarlyView.
Effective population size (Ne) is a useful parameter to evaluate the long‐term viability of populations. While obtaining enough field data from wild populations to estimate Ne directly is challenging, molecular techniques applied to non‐invasive samples provide an appealing alternative.
