Individual movement modeling expands the power of migratory species observations: North Atlantic right whale case study

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Understanding a population's distribution depends on observing the presence and movement of individuals throughout their range. For highly mobile marine species, these observations typically rely on high effort monitoring programs. Tracking enough individuals to understand trends in movement behavior is not always logistically feasible, and ...

Optical‐to‐Microcomb Stability Transfer for Ultrastable Timing and Microwave/Millimeter‐Wave Generation

open access: yesLaser &Photonics Reviews, EarlyView.
This work demonstrates a high‐fidelity stability transfer from an optical reference to a high‐repetition‐rate microcomb using a mode‐locked laser bridge. By employing electro‐optic sampling timing detection, femtosecond‐level synchronization and 10−18‐level fractional frequency stability are achieved.

Coaxial Dipole Array With Switching Transmit Sensitivities for Ultrahigh Field MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To investigate dipole antennas with electronically switchable transmit field patterns to improve flip angle homogeneity in ultra‐high field MRI. Methods Reconfigurable dipole elements that could produce two distinct electronically switchable B1+$$ {B}_1^{+} $$ field profiles were conceptualized and constructed. Eight such elements were
