Whole‐Brain Diffusion MRI at 7T With Universal Multiband GRAPE pTx Pulses

open access: yesMagnetic Resonance in Medicine, EarlyView.
Purpose To improve signal strength and homogeneity of whole‐brain diffusion‐weighted imaging (DWI) at 7T. Methods Universal multiband excitation and refocusing pulses were optimized with the gradient ascent pulse engineering (GRAPE) algorithm across a database of B1+$$ {B}_1^{+} $$ and B0$$ {B}_0 $$ maps obtained from 20 subjects.

Predicting Mesoscopic Larmor Frequency Shifts in Ex Vivo Porcine Optic Nerve

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Larmor frequency shifts in white matter (WM) vary with fiber orientation due to anisotropic microstructure. Since clinical voxels are significantly larger than these microscopic frequency variations, the measured signal represents a bulk average of local shifts.

Awake Blue Laser Excision and Balloon Dilation of Oropharyngeal Stenosis in High‐Risk Patients

open access: yesOtolaryngology–Head and Neck Surgery, EarlyView.
Abstract Oropharyngeal stenosis is a rare condition that can develop following head and neck cancer treatment, leading to progressive dyspnea, dysphagia, and dysphonia. Patients with symptomatic dyspnea may benefit from endoscopic surgery. However, head and neck cancer survivors can have severe trismus, limited neck extension, and altered laryngeal ...

Interplanetary frontiers: terraforming from an invasion science perspective

open access: yesOikos, EarlyView.
The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

A framework for investigating fish population density responses to habitat fragmentation

open access: yesOikos, EarlyView.
Globally, fish populations that rely on rivers are being fragmented by in‐stream barriers, but it is unclear how pervasive any negative population responses to fragmentation are. We developed a modeling framework for estimating density responses of fishes upstream and downstream of in‐stream barriers and applied it to learn how low‐head dams have ...
