Spatial modelling of agro-ecologically significant grassland species using the INLA-SPDE approach

open access: yesScientific Reports, 2023
The use of spatially referenced data in agricultural systems modelling has grown in recent decades, however, the use of spatial modelling techniques in agricultural science is limited.

Precursory Indicator for Mode I Fracture in Brittle Rock through Critical Slowing Down Analysis

open access: yesShock and Vibration, 2020
The abrupt rock-related hazards, such as landslide, rock burst, and collapse, seriously threaten the safety and service life of engineering works. Precursory information on critical transitions preceding sudden fracture is of great significance in rock ...

Sources of residual autocorrelation in multiband task fMRI and strategies for effective mitigation

open access: yesFrontiers in Neuroscience, 2023
IntroductionAnalysis of task fMRI studies is typically based on using ordinary least squares within a voxel- or vertex-wise linear regression framework known as the general linear model.

Walsh Spectral Techniques for Logic Synthesis FPGA

open access: yesAdvances in Electrical and Electronic Engineering, 2015
The implementation value of multi-output Boolean functions in logic synthesis FPGA can be reduced by using Walsh spectral representation. This paper proposes an algorithm for calculating the maximum coefficient of the autocorrelation function of BF ...

Activity autocorrelation in financial markets. A comparative study between several models

open access: yes, 2003
We study the activity, i.e., the number of transactions per unit time, of financial markets. Using the diffusion entropy technique we show that the autocorrelation of the activity is caused by the presence of peaks whose time distances are distributed ...

Synchrotron Radiation for Quantum Technology

open access: yesAdvanced Functional Materials, EarlyView.
Materials and interfaces underpin quantum technologies, with synchrotron and FEL methods key to understanding and optimizing them. Advances span superconducting and semiconducting qubits, 2D materials, and topological systems, where strain, defects, and interfaces govern performance.

Fast Autocorrelated Context Models for Data Compression [PDF]

open access: yes, 2013
A method is presented to automatically generate context models of data by calculating the data's autocorrelation function. The largest values of the autocorrelation function occur at the offsets or lags in the bitstream which tend to be the most highly ...
