Dynamic Hyperbolic Tangent PSO-Optimized VMD for Pressure Signal Denoising and Prediction in Water Supply Networks

open access: yesEntropy
Urban water supply networks are prone to complex noise interference, which significantly degrades the performance of data-driven forecasting models. Conventional denoising techniques, such as standard Variational Mode Decomposition (VMD), often rely on ...

Urbanization and food transition in the Brazilian Amazon: From wild to domesticated meat

open access: yesPeople and Nature, EarlyView.
Abstract Urbanization is expected to influence food transitions, resulting in a shift from wild foods to more domesticated foods. Concomitantly, food insecurity and urban demand for natural resources, including wildlife, are expected to increase overall, even when the per capita consumption is expected to decrease.

Impact of Stabilizing Osmolytes on the Conformational Dynamics of Human and Rat Islet Amyloid Polypeptides

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The aggregation of human islet amyloid polypeptide (hIAPP) into cytotoxic oligomers and amyloid fibrils is a hallmark of type 2 diabetes mellitus (T2DM), leading to pancreatic β‐cell dysfunction. In contrast, rat IAPP (rIAPP) is largely non‐amyloidogenic. Osmolytes such as glucose, glycerol, and sorbitol are known to stabilize globular protein

Epx4 Nanopore With Multiple Constrictions for Single‐Molecule Identification

open access: yesSmall Methods, EarlyView.
Epx4 is a biological multi‐constriction nanopore that generates informative current signals for polypeptide sensing. Compared with α‐hemolysin, Epx4 detects short poly‐L‐lysine (S‐PLL, Mw 10 kDa) at a higher event frequency and produces signal features that distinguish it from long poly‐L‐lysine (L‐PLL, Mw 30–70 kDa), with an ROC AUC of 0.82 for the ...

Prediction of significant wave height using a VMD-LSTM-rolling model in the South Sea of China

open access: yesFrontiers in Marine Science
Accurate prediction of significant wave height is crucial for ocean engineering. Traditional time series prediction models fail to achieve satisfactory results due to the non-stationarity of significant wave height.

Pickin' up good vibrations: a systematic review of footfall detection and analysis in the realm of wildlife surveying

open access: yesWildlife Biology, EarlyView.
Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.
