Differentiation of Plant and Animal‐Derived Cholesterol Using irm‐13C NMR and IRMS

open access: yesMagnetic Resonance in Chemistry, EarlyView.
Determining and certifying the origin of ingredients, starting materials, and excipients used in manufactured goods like cosmetics and medicines can be difficult. In this report, we describe a robust approach for identifying the origin of cholesterol, a component of myriad consumer products using irm‐13C NMR and IRMS to differentiate plant versus ...

Multi-Frame Super-Resolution of Gaofen-4 Remote Sensing Images

open access: yesSensors, 2017
Gaofen-4 is China’s first geosynchronous orbit high-definition optical imaging satellite with extremely high temporal resolution. The features of staring imaging and high temporal resolution enable the super-resolution of multiple images of the same ...

Neural network with signal parameters featuring for near‐surface velocity model building

open access: yesNear Surface Geophysics, EarlyView.
Abstract This study presents a method that integrates spectral recomposition (SR) with a neural network to improve near‐surface seismic analysis. The approach incorporates SR‐derived wavelet‐timing attributes into a fully convolutional network (FCN) to enhance the characterization of shallow subsurface structures. Field evaluation was conducted using S‐

SMILE: Extraction‐free submicron‐resolution mapping of lipid chain length and unsaturation by stimulated Raman imaging

open access: yesVIEW, EarlyView.
In this work, we develop submicron‐resolution mapping of intracellular lipid elements (SMILE) as an extraction‐free vibrational spectroscopic imaging platform based on hyperspectral stimulated Raman scattering microscopy with a spectral analysis pipeline for pixel‐resolved lipid profiling.

Domination Versus Sisterhoods in the Blood Microbiota of Migrating Birds: Patterns of Within‐ and Between‐Individual Blood Parasite Diversity Revealed Through Metabarcoding

open access: yesIntegrative Zoology, EarlyView.
Avian haemosporidian blood parasites are typically identified through Sanger sequencing of a partial cytochrome b fragment, the MalAvi barcoding region. Next‐generation sequencing is seldom used for avian blood parasite identification; this study demonstrates a higher detection rate of co‐infections via metabarcoding and its possible implications ...

Iteratively Reweighted Blind Deconvolution With Adaptive Regularization Parameter Estimation

open access: yesIEEE Access, 2017
In many realistic image processing applications, the acquired images often suffer from mixed noises and blurring, which greatly degrade the image quality.

The Emerging Short Chain Fatty Acid Enriched Metabotype in Irritable Bowel Syndrome and Its Potential Clinical Relevance

open access: yesAlimentary Pharmacology &Therapeutics, EarlyView.
In a cohort of IBS‐D patients recruited to the TRITON study, faecal metabolomic profiling reveals a SCFA‐enriched metabotype associated with increased pain and urgency, altered stool characteristics and accelerated intestinal transit. ABSTRACT Background Metabolomic analysis in irritable bowel syndrome (IBS) has identified metabotypes enriched in ...

On optimisation of Paganin's method for propagation‐based X‐ray phase‐contrast imaging and tomography

open access: yesJournal of Microscopy, EarlyView.
Abstract Paganin's method for image reconstruction in propagation‐based phase‐contrast X‐ray imaging and tomography has enjoyed broad acceptance in recent years, with over one thousand publications citing its use. The present paper discusses approaches to optimisation of the method with respect to simple image quality metrics, such as signal‐to‐noise ...
