Autonomy for MRI Field Cameras: Synchronization, Self‐Calibration, and Sequence Detection
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose This work aims to provide a workflow for operating NMR field probes in MR scanners independently of pulse programming, scanner TTL trigger pulses and dedicated calibration sequences. Methods An independent timing system and limited prior knowledge about relative probe positions enable synchronous field measurement, probe position ...

Interaction Between Vortex‐Induced Vibrations and Base Vibrations in Piezoelectric Harvesters
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT In the present era, powering sensors using green energy is a significant challenge. One promising solution for the power supply of small sensors relies on piezoelectric energy harvesters excited by vortex‐induced vibrations (VIVs) generated by wind.

Modulation of wind drag by tidal currents in an embayment
Quarterly Journal of the Royal Meteorological Society, EarlyView.Tidal currents modulate how wind energy enters the surface wave field by influencing both wave drag and wave generation. In Shark Bay, following currents reduce effective wave steepness and wind drag, and opposing currents enhance wave growth. Wind energy is partitioned between wave drag and the creation of new waves, explaining observed tidal ...

Who Does Bogotá “Care” for? Care Blocks, Care Workers and the Sustainable Development Goals
Sustainable Development, EarlyView.ABSTRACT This paper critically examines Bogotá's District Care System within the framework of urban social sustainability and the Sustainable Development Goals (SDGs). Focusing on the Care Blocks (Manzanas del Cuidado), it employs a mixed‐methods approach—legal analysis, interviews, testimonies, surveys, and InfoCuidado data—to explore the paradox of a

Sustainable Development, EarlyView.ABSTRACT Farmers' capabilities, a core component of social sustainability, have been largely neglected in sustainable agriculture discourse. Using a relational approach to capabilities and autonomy, this study explores how women farmers translate the opportunity of agricultural innovation into their valued outcomes, and which factors shape their ...
