Flux: Elegant machine learning with Julia

Journal of Open Source Software, 2018
Flux is library for machine learning (ML), written using the numerical computing language Julia (Bezanson et al. 2017). The package allows models to be written using Julia’s simple mathematical syntax, and applies automatic differentiation (AD) to ...

Spatial-temporal distribution patterns change of grassland formation in Inner Mongolia since the 1980s

Ecological Indicators
This study evaluates the degradation of Inner Mongolian grasslands from 1980 to 2020 by analysing changes in grassland formations. A random forest-based machine learning classification model was developed using the Vegetation Map of China (1:1,000,000 ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Experimental Study on the Electromagnetic Forming Behavior of Pre-Painted Al 99.0 Sheet

Journal of Manufacturing and Materials Processing
Development of forming methods for surface-coated metals is a current concern due to their economic and environmental advantages. For a successful forming operation, it is necessary that both components, the substrate and the coating, are able to ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Remotely sensed dune celerity and sand flux measurements of the world's fastest barchans (Bodele, Chad)

, 2008
Quantifying sand flux with field measurements is an expensive and time-consuming process. We here present an alternative approach using the COSI-Corr software package for Earth surface deformation detection.

Magnetic flux density distribution in axial flux machine cores [PDF]

, 2005
[Abstract]: A three-dimensional analytical model is presented to evaluate the magnetic flux density distribution in the core of an axial flux machine. The model predicts significantly higher flux density near the outer radius of the core than that at the

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Comments on Flux and Flux Density

HortScience, 1988
Abstract A recent update supplement of the ASHS Publications Manual (1) states that photosynthetic photon flux density (PPFD) shall now be called photosynthetic photon flux (PPF). This decision appears to be based on a Feature article by Holmes et al.

Genetic modification of flux for flux prediction of mutants [PDF]

Bioinformatics, 2009
Abstract Motivation: Gene deletion and overexpression are critical technologies for designing or improving the metabolic flux distribution of microbes. Some algorithms including flux balance analysis (FBA) and minimization of metabolic adjustment (MOMA) predict a flux distribution from a stoichiometric matrix in the mutants in which some
