Optimizing Selective RF Pulses for Enhanced Signal Stability in Turbo Spin Echo Using a Differentiable Extended Phase Graph Model

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To improve slice profile consistency across echo trains in turbo spin echo (TSE) imaging, thereby reducing image blurring and increasing the accuracy of multi echo spin echo T2$$ {T}_2 $$ mapping. Methods Excitation and refocusing RF pulses were optimized for TSE using a differentiable extended phase graph model that incorporates the ...

Melodies of the forest: Nature as an improvisational space for shared creative embodiment

open access: yesPeople and Nature, EarlyView.
Abstract In an era marked by increasing disconnection from nature, innovative approaches to reconnect with the environment are crucial for both ecological and psychological well‐being. This paper explores how natural environments (a deciduous forest of Quebec in the present case study) can serve as an improvisational space for shared creative ...

From maps to mandates: Multitemporal vegetation cover analysis as a tool to evaluate environmental judicial decisions

open access: yesPeople and Nature, EarlyView.
Abstract This study examines the use of multitemporal vegetation cover analysis as a tool to assess the ecological effectiveness of judicial decisions that recognize the rights of nature, using Colombia's 2016 T‐622 decision on the Atrato River as a case study.

Developing ocean literacy through a relational model: Exploring outcomes of a place‐based ocean education programme in primary schools

open access: yesPeople and Nature, EarlyView.
Abstract Schools are a common place where the younger generation can develop their understanding of the ocean and acquire the skills needed to become responsible and knowledgeable ocean advocates. Grounded in a relational ocean literacy model, this study examined outcomes of a place‐based programme integrating picture books, beach excursions and ...

Prediction of Cure‐Induced Wrinkles Aimed at the Manufacturing of Large Wind Turbine Blades

open access: yesPolymer Composites, EarlyView.
The step‐wise progression of the development of cure‐induced wrinkles. Before curing, at room temperature the laminate is resting at the mould face. In the next step, the wrinkle is developing due to thermal gradients. At the end of curing, the composite has cooled down and the undulation is left in, byt the increase in resin stiffness across the ...

Full-Diversity Space-Time Error Correcting Codes with Low-Complexity Receivers

open access: yesEURASIP Journal on Wireless Communications and Networking, 2011
We propose an explicit construction of full-diversity space-time block codes, under the constraint of an error correction capability. Furthermore, these codes are constructed in order to be suitable for a serial concatenation with an outer linear ...

Bio‐Based Multilayer Composites Based on Blended Electrospun Fibers and Luffa Cylindrica for Enhanced Low‐Frequency Noise Absorption

open access: yesJournal of Polymer Science, EarlyView.
Bio‐based multilayer composites consisting of Luffa Cylindrica and electrospun microfibers exhibit enhanced sound absorption, shifting peak performance towards lower frequencies. The multilayer configuration improves acoustic wave dissipation, providing a tunable and sustainable solution for urban and traffic‐related noise mitigation.

Using large language models to automate herbarium specimen transcription: A case study at the Missouri Botanical Garden

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Biological specimens housed in natural history collections are indispensable resources for documenting where species occur and how they have changed through time, and are thus vital for combating biodiversity loss. Digitization of these collections promises to make these critical resources globally available.
