Coding Prony’s method in MATLAB and applying it to biomedical signal filtering

BMC Bioinformatics, 2018
Background The response of many biomedical systems can be modelled using a linear combination of damped exponential functions. The approximation parameters, based on equally spaced samples, can be obtained using Prony’s method and its variants (e.g.

Normative scores and clinical cut‐offs of the Cyclothymic–Hypersensitive Temperament Questionnaire in adolescence

JCPP Advances, EarlyView.
Abstract Background The Cyclothymic–Hypersensitive Temperament (CHT) is a multidimensional, transdiagnostic affective disposition characterized by mood instability, interpersonal sensitivity, heightened emotional reactivity and impulsive behaviors. The CHT Questionnaire (CHTQ) currently lacks of normative references and empirically derived thresholds ...

Soil Loosening of Compacted Urban Tree Sites Using a Pneumatic Lance Injector: Quantifying Treatment Success Through Tree Morphology and Soil Structure Parameters via Terrestrial Laser Scanning

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Urban trees provide essential ecosystem services, but their growth and longevity are often limited by soil compaction. Although pneumatic lance injection (PLI) is increasingly promoted as a minimally invasive and efficient soil loosening technique, but robust scientific evidence for its long‐term effectiveness remains limited.

QGeoSEP: A Novel Multi‐Task Learning Framework Integrating Quantum, Geometric, and Semantic Features for Collaborative Prediction of Multiple Properties With Potential Application to Energetic Materials

Materials Genome Engineering Advances, EarlyView.
We introduce QGeoSEP, a multi‐task learning framework for accurate energetic material property prediction, with competitive performance against mainstream baselines and an accessible online tool for efficient molecular evaluation. ABSTRACT Accurate physicochemical property prediction is critical for the rational design of energetic materials (EMs), yet

Adaptive Beamforming for Sparse Array Based on Semi-Definite Programming

IEEE Access, 2018
An adaptive beamforming (ABF) technique for sparse receiving arrays with gain/phase uncertainties is proposed. The basic idea of the proposed method is using the compressed sensing theory to estimate directions and amplitudes of the received signals with

Taxonomic reappraisal of the mangrove genus Avicennia (Acanthaceae) in India

Nordic Journal of Botany, EarlyView.
A taxonomic reappraisal of the mangrove genus Avicennia in India was undertaken through extensive field surveys and critical examination of herbarium specimens. Three taxa, Avicennia alba, Avicennia marina subsp. marina, and Avicennia officinalis, are described in detail. A synonymic list was compiled using the World Checklist of Vascular Plants (WCVP)

Total least-squares EIO model, algorithms and applications

Geodesy and Geodynamics, 2019
A functional model named EIO (Errors-In-Observations) is proposed for general TLS (total least-squares) adjustment. The EIO model only considers the correction of the observation vector, but doesn't consider to correct all elements in the design matrix ...

Robust Performance Loss Rate Calculation for Photovoltaic Systems in High Latitude Locations

Progress in Photovoltaics: Research and Applications, EarlyView.
This work studies the best methods for performance loss rate (PLR) calculation in high latitude locations, characterized by strong seasonal variability. As the different methods can drastically affect the PLR value, an ensemble method consisting of multiple approaches was validated to be essential in identifying robust PLRs.

HvarAKR1B1‐mediated tolerance in Hippodamia variegata: Deciphering the metabolic adaptation and fitness costs under prolonged starvation

Pest Management Science, EarlyView.
Starvation stress significantly affected the growth and development of Hippodamia variegata. Combined transcriptome and metabolome analysis and RNA interference verification revealed that HvarAKR1B1 may be involved in the response of Hippodamia variegata to starvation stress.
