The PhenoChange network protocol for monitoring leaf phenology in tropical dry ecosystems using phenocameras

Methods in Ecology and Evolution, EarlyView.
Abstract Tropical dry ecosystems (TDEs) cover half of the tropics and play a key role in global carbon dynamics. TDEs present distinct canopy and ground layers that often exhibit contrasting phenological patterns. On‐the‐ground observations of phenology by the human eye, though valuable, may suffer from limited temporal resolution and observer biases ...

A new approach for detecting phenological change using Time of Emergence (ToE) methodology

Methods in Ecology and Evolution, EarlyView.
Abstract Many species are responding to environmental change by shifting the timings of phenological events such as migration or reproduction. These shifts are typically reported as rates of change, which do not indicate when such shifts transcend their original states, nor consider whether species experience novel environmental conditions or ...

Hybrid Framework for Cartilage Damage Detection from Vibroacoustic Signals Using Ensemble Empirical Mode Decomposition and CNNs

Sensors
This study proposes a hybrid analytical framework for detecting chondromalacia using vibroacoustic (VAG) signals from patients with knee osteoarthritis (OA) and healthy controls (HCs).

Measuring the time‐varying market efficiency in the prewar and wartime Japanese stock market, 1924–1943

Asia‐Pacific Economic History Review, Volume 65, Issue 1, Page 131-159, March 2025.
Abstract This study examines the adaptive market hypothesis in the prewar and wartime Japanese stock market using a new market capitalization‐weighted price index. First, we find that the degree of market efficiency varies over time and with major historical events. This implies that the hypothesis is supported in this market.

Generating Synthetic Data Using 2D Multifractal Detrended Fluctuation Analysis Generative Adversarial Networks

IEEE Access
A novel 2-dimensional Multifractal Detrended Fluctuation Analysis (2D-MFDFA) as a discriminator for Generative Adversarial Networks (GAN) is presented in this work. The proposed approach demonstrates improved generated data quality at early iterations on

Heart‐Rate Variability and Its Role in Non‐Cardiac Surgery Perioperative Care: Scoping Review

ANZ Journal of Surgery, EarlyView.
ABSTRACT Background Heart rate variability (HRV) is a non‐invasive method of assessing autonomic function. Those with autonomic dysfunction may be at heightened risk of peri‐operative complications due to sympatho‐parasympathetic imbalance. This review summarises the clinical applications of HRV, approaches to how it is measured, and its role in ...
