Scalable spokes pTx pulses for 2D turbo‐spin‐echo imaging at 7 T

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose Turbo spin echo (TSE) is important clinically. Unfortunately, 7 T TSE suffers from B1+‐induced signal dropouts. Magnitude‐based parallel transmit (pTx) pulse design algorithms cannot enforce phase patterns complying with the Carr‐Purcell‐Meiboom‐Gill conditions (90° phase shift between excitation and refocusing).

Distilling food web dynamics: top–down and bottom–up drivers of extinction and trophic cascades

open access: yesOikos, EarlyView.
Quantifying population dynamics is a fundamental challenge in ecology and evolutionary biology, particularly for species that are cryptic, microscopic, or extinct. Traditional approaches rely on continuous representations of population size, but in many cases, the precise number of individuals is unknowable.
