International Cocoa Trading Arrangements Between Industrialised and Developing Countries 1951–1999: A Structural Gravity Analysis

The World Economy, EarlyView.
ABSTRACT Using a state‐of‐the‐art structural gravity model, we investigate the impact of various (post‐)colonial cocoa trading arrangements on the cocoa trade between developing cocoa producer countries and rich industrial cocoa consumer nations in the time period 1951–1999. We find that in particular the trading arrangements of the European (Economic)

Graph Signal Processing: History, development, impact, and outlook

, 2023
Signal processing (SP) excels at analyzing, processing, and inferring information defined over regular (first continuous, later discrete) domains such as time or space.

Microanatomical features of bovids long bones: What are the effects of mass and habitat?

Journal of Anatomy, Volume 249, Issue 4, Page 899-923, October 2026.
This study provides the first qualitative and quantitative exploration of inter‐bones and interspecific variations in the microanatomy of long bones in bovids in response to significant changes in body mass and habitat. Abstract Bovids are a valuable group for studying limb long bone adaptations due to differences in size and the environment that the ...

Extreme Learning Machine for Graph Signal Processing

, 2018
In this article, we improve extreme learning machines for regression tasks using a graph signal processing based regularization. We assume that the target signal for prediction or regression is a graph signal.

Increased expression of inflammasome signaling genes and proteins in selective brain regions in the intermediate stage of Alzheimer's disease

Brain Pathology, Volume 36, Issue 5, September 2026.
Neuritic plaques increase in the intermediate stage of Alzheimer's neuropathological change. The intermediate stage of Alzheimer's disease was investigated by transcriptomics and immunohistochemistry. This revealed that inflammasome sensors NLRP1, NLRP3, and AIM2 oligomerize with ASC speck to form the inflammasome complex and initiate the downstream ...

Graph Signal Processing Of Human Brain Imaging Data

, 2018
Modern neuroimaging techniques offer disctinct views on brain structure and function. Data acquired using these techniques can be analyzed in terms of its network structure to identify organizing principles at the systems level. Graph representations are

HELIOS ‐ Highly rEliable Links durIng sOlar conjunctionS

Radio Science, Volume 61, Issue 8, August 2026.
Abstract During deep space missions, maintaining reliable communication between a spacecraft and Earth becomes particularly challenging during superior solar conjunctions, when the spacecraft passes behind the Sun relative to Earth. The highly ionized solar corona and solar wind create plasma inhomogeneities that severely affect radio signals, leading ...

Wide-sense stationarity and spectral estimation for generalized graph signal

, 2022
We consider a probabilistic model for graph signal processing (GSP) in a generalized framework where each vertex of a graph is associated with an element from a Hilbert space.

Network‐level disconnectivity tracks poststroke depressive symptom improvement

Psychiatry and Clinical Neurosciences, Volume 80, Issue 8, Page 676-681, August 2026.
Aims Poststroke depression is the most common psychological condition following a stroke and can severely impact outcome. However, the neurobiological biomarkers associated with recovery of poststroke depression remain unclear. In this longitudinal observational study, we set out to investigate the effect of lesion‐induced focal damage and network ...
