Red‐to‐Near‐Infrared Fluorescence Resonance Energy Transfer Reporters for Dual Imaging Applications

open access: yesSmall Methods, EarlyView.
Genetically encoded FRET biosensors reveal dynamic signaling in living cells, but overlapping spectra have limited the simultaneous monitoring of multiple pathways. We introduce a red‐to‐near infrared FRET pair, mRuby2/miRFP670nano3, compatible with existing reporters and enabling dual FLIM‐FRET without bleed‐through.

New 2D-Variational Mode Decomposition-Based Techniques for Seismic Attribute Enhancement

open access: yesApplied Sciences
Seismic attributes are widely used to enhance the interpretation of structural, stratigraphic, and lithologic features in subsurface data. Their effectiveness, however, can be limited by noise, resolution constraints, and processing artifacts. This study

How We Simulate Nanopores

open access: yesSmall Methods, EarlyView.
Nanopore technology has revolutionized single‐molecule sensing, yet it suffers from an inherent interpretive challenge. Molecular dynamics has emerged as a go‐to method for determining the relationship between the structure of translocating molecules and the nanopore current signals.

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.

An Improved Sparrow Search Algorithm for the Optimization of Variational Modal Decomposition Parameters

open access: yesApplied Sciences
Variational modal decomposition (VMD) is frequently employed for both signal decomposition and extracting features; however, the decomposition outcome is influenced by the quantity of intrinsic modal functions (IMFs) and the specific parameter values of ...

Confinement‐Induced Enhancement of Solid‐State Emission Quantum Yield in Rubrene@MOF Hybrid Materials

open access: yesZeitschrift für anorganische und allgemeine Chemie, EarlyView.
Pore‐size‐controlled nanoconfinement of rubrene within UiO‐66 and UiO‐67 suppresses aggregation‐caused quenching and restores bright solid‐state emission. Geometric exclusion and energetic destabilization prevent parallel stacking, yielding solution‐like absorption and fluorescence quantum yields up to 25%.

A combined model for short-term traffic flow prediction based on variational modal decomposition and deep learning

open access: yesScientific Reports
The emergence of Deep Learning provides an opportunity for traffic flow prediction. However, uncertainty and volatility exhibited by nonlinearity and instability of traffic flow pose challenges to Deep Learning models.

Recognition of Spatiotemporal Feature Images of Zero‐Sequence Voltage for Single‐Phase High‐Impedance Ground Faults Under Complex Conditions

open access: yesHigh Voltage, EarlyView.
ABSTRACT Diagnosing high‐impedance ground faults (HIGFs) in distribution networks is extremely challenging because high transition resistance significantly reduces electrical signal strength and unpredictable initial fault phase angles coupled with asymmetric voltage disturbances often lead to misclassification.
