Next Generation 7 Tesla Arterial Spin Labeling With Rotated Spiral Acquisition Enables Mesoscale Resolution in 3D Brain Perfusion and Functional MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To achieve high resolution (≤ 1 mm isotropic) whole‐brain perfusion imaging at 7 T with next generation ASL pulse sequence, reconstruction algorithm, and MRI hardware. Methods We capitalized on three major innovations: (1) FLASH‐based pseudo‐Continuous ASL (pCASL) sequence with rotated golden‐angle stack‐of‐spirals (rGA‐SoS) sampling; (

Respiratory Motion‐Corrected Model‐Based 3D Water‐Fat MRA of the Thorax at 0.55 T

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose The goal of this study was to develop a 5‐min 3D MRA acquisition at 0.55 T with predictable scan time, 100% data efficiency, and robust water‐fat separation. Methods For full data efficiency, the proposed method combined self‐gating with retrospective motion correction while ensuring a predictable 5‐min scan time.

Scheduling Bodyguards

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT Security agencies around the world use bodyguards to protect government officials and public figures. In this paper, we consider a two‐person zero‐sum game between a defender who allocates such bodyguards to protect several targets and an attacker who chooses one target to attack.

Interrelationships among handgrip strength, body composition, physical activity, and quality of life in adults with cystic fibrosis: A cross‐sectional study

open access: yesNutrition in Clinical Practice, EarlyView.
Abstract Background In individuals with cystic fibrosis (CF), lean mass and muscle strength are important predictors of clinical outcomes. This study evaluated associations among body composition, handgrip strength, muscle quality, physical activity, and health‐related quality of life in CF. Methods This observational, cross‐sectional study included 27

Time tells: plasticity and developmental asynchrony underlie trait variation in a dune‐building grass

open access: yesOikos, EarlyView.
Habitat‐modifying plants engineer landscapes through plant‐environment feedbacks. The strength of these feedbacks is determined by above‐ and below‐ground traits shaping landscape morphology. Besides interspecific differences, recent findings highlight that intraspecific trait variation, such as shoot density, can also influence landscape morphology ...

Conserving wildlife through demand reduction and supply alternatives: Two experiments in restaurants in Kinshasa

open access: yesPeople and Nature, EarlyView.
Abstract High aggregate levels of wildlife consumption in cities in Central Africa highlight the need for solutions that balance wildlife protection, local livelihoods and the relational values between people and nature. This study explores the impacts of demand‐ and supply‐side interventions on wild meat consumption through two randomized control ...
