3D Closed‐Loop Navigation of Magnetic Microswimmers Using Vision‐Derived Depth Feedback

open access: yesAdvanced Intelligent Systems, EarlyView.
A planar magnetic microswimmer is navigated in three dimensions under a standard microscope. Image defocus supplies a real‐time depth cue, and model‐predictive control with A* planning steers the body on surfaces and in free swimming. Axial position is regulated by propulsion alone, without magnetic field gradients or extra cameras.

The causal effect of agricultural landscape simplification on Germany's grasslands during a compound drought and heatwave in 2018

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Preserving ecosystem services, along with economic and environmental benefits, will require future landscape policies to identify and incorporate relevant landscape features. In this paper, we investigate the causal effect of agricultural landscape simplification on drought‐related grassland damages.

Internet use and adolescent development: A conceptual model integrating behavioral and contextual theories

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract In the digital era, adolescent development is deeply embedded in the cyber environment. Despite ongoing debate on the benefits and/or risks that Internet use brings to adolescents in empirical studies, conceptual and theoretical discussion on the influences of the intensity and modalities of Internet use is peripheral.

Prenatal Evaluation of RNU4‐2 Variants in Fetuses With Central Nervous System Anomalies

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Fetal central nervous system (CNS) anomalies are among the most common congenital malformations, yet the overall prenatal diagnostic yield of current genetic testing remains below 40%. Variants in RNU4‐2, a non‐coding gene encoding the U4 small nuclear RNA (snRNA), have recently been linked to a novel highly recurrent dominant ...
