Community composition, abundance and activity‐density of carabids and staphylinids depend on prey abundance and adjacent habitat even in diverse agricultural landscapes

open access: yesPest Management Science, EarlyView.
Carabid and staphylinid communities are shaped by adjacent habitat type, prey availability and landscape context, influencing natural pest control across agricultural landscapes. Abstract BACKGROUND The functioning of agroecosystems depends on key ecosystem processes that deliver ecosystem services, yet agricultural management has increasingly shifted ...

Phase I Multivariate Coefficient of Variation Control Charts for High‐Dimensional Processes

open access: yesQuality and Reliability Engineering International, EarlyView.
ABSTRACT Multivariate control charts have traditionally focused on monitoring the process mean vector and/or covariance matrix. Recent studies have extended this framework to Phase II monitoring of the multivariate coefficient of variation (MCV); yet very limited work has examined MCV‐based monitoring in Phase I.

Electroencephalogram fractal dimension as a measure of depth of anesthesia

open access: yes, 2008
This paper proposes a combined method including adaptive segmentation and Higuchi fractal dimension (HFD) of electroencephalograms (EEG) to monitor depth of anesthesia (DOA).

A Methodological Pathway for Supporting the Transition From Theory to Practice in Action‐Oriented Research for Transformative Change

open access: yesSustainable Development, EarlyView.
ABSTRACT Over recent decades, action‐oriented research has gained prominence in co‐producing actionable knowledge to drive transformative change toward sustainability. However, further methodological developments are needed to support the transition to the application phase of such knowledge.

Wavelet Multiresolution Analysis of High-Frequency FX Rates, Summer 1997 [PDF]

open access: yes
FX pricing processes are nonstationary and their frequency characteristics are time-dependent. Most do not conform to geometric Brownian motion, since they exhibit a scaling law with a Hurst exponent between zero and 0.5 and fractal dimensions between 1 ...

Fractal Analysis and Imaging in Geosciences

open access: yes, 2012
The aim of this work is to show the contribution of one-dimensional fractal analysis and its generalization to two dimensions, using the continuous wavelet transform (CWT). The objective is to derive information by analyzing geophysical signals. This is achieved by the continuous wavelet transform modulus maxima technique.
