Comparative evaluation of supervised and unsupervised deep learning strategies for denoising hyperpolarized 129Xe lung MRI

open access: yesMagnetic Resonance in Medicine, EarlyView.
Abstract Purpose Reduced signal‐to‐noise ratio (SNR) in hyperpolarized 129Xe MR images can affect accurate quantification for research and diagnostic evaluations. Thus, this study explores the application of supervised deep learning (DL) denoising, traditional (Trad) and Noise2Noise (N2N) and unsupervised Noise2void (N2V) approaches for 129Xe MR ...

Sedum diversiflorum sp. nov. (Crassulaceae), a new species with variable merosity from the Satsunan Islands, Kagoshima, Japan

open access: yesNordic Journal of Botany, EarlyView.
We re‐examined the taxonomic status of a plant previously identified as Sedum formosanum subsp. formosanum from four islands in the Satsunan Islands, Japan. To clarify its taxonomic identity, we conducted morphological and phenological comparisons and performed molecular phylogenetic analyses based on nuclear internal transcribed spacer (ITS) and three

Synthesis of Polyaniline Nanoparticles With High Surface Area for CO2 and N2 Sorption

open access: yesNatural Sciences, EarlyView.
Polyaniline nanoparticles (PANI NPs) in emeraldine salt and emeraldine base forms were synthesized with and without HCl to optimize gas sorption. HCl treated PANI ES reached a CO2 uptake of 30.6 cm3/g, while PANI EB exhibited exceptional N2 adsorption (144.4 cm3/g) and the highest reported specific surface area for oxidatively polymerized PANI (70.8 m2/

Bifunctional MOF‐on‐MOF‐Derived CuCo2O4 for Oxygen Evolution Reaction Electrocatalysis and Supercapacitor Electrodes

open access: yesChemistryOpen, EarlyView.
A bifunctional copper cobalt oxide derived from metal‐organic frameworks was synthesized with a spinel structure and coral reef‐like morphology. It showed excellent activity for the oxygen evolution reaction, with overpotential of 317 mV at 10 mA cm−2 and Tafel slope of 49 mV dec−1.

Barriers and opportunities for consumption of invasive lionfish in Belize

open access: yesPeople and Nature, EarlyView.
Abstract Invasive lionfish (Pterois spp.) have rapidly spread across the Western Atlantic and Mediterranean Sea. They reproduce frequently and consume native marine life important to livelihoods and reef health. To combat the deleterious impacts of this species, management efforts in Belize and throughout the invaded range have included development of ...
