HPoolGCL: Augmentation‐Free Cross‐Granularity Graph Contrastive Learning With Hierarchical Pooling
CAAI Transactions on Intelligence Technology, EarlyView.ABSTRACT Graph contrastive learning (GCL) has emerged as a dominant paradigm for self‐supervised representation learning for attributed graph data. However, existing GCL methods heavily rely on empirical graph data augmentation, which may distort intrinsic graph semantics and produce poor generalisation without carefully chosen or designed augmentation

Topics in Cognitive Science, EarlyView., 2023 Abstract Over the past several decades, research in the cognitive sciences has foregrounded the importance of active bodies and their continuous dependence on the changing environment, strengthening the relevance of dynamical models. These models have been steadily developed within the ecological psychology approach to cognition, which arguably ...

A Model of the Production Potential with Managed Factors of Inefficiency [PDF]
The results of applied research on estimation of the production potential based on the methodology of the stochastic frontier production function are presented in the paper. The comparative analysis of the stochastic frontier models by means of estimates

Demographic buffering in natural populations: A multi‐level perspective
Journal of Animal Ecology, EarlyView.We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.

Efficiency of Hospitals in the Czech Republic [PDF]
The paper estimates cost efficiency of 99 general hospitals in the Czech Republic during 2001-2008 using Stochastic Frontier Analysis. We estimate a baseline model and also a model accounting for various inefficiency determinants.

Australian Journal of Agricultural and Resource Economics, EarlyView.ABSTRACT China's diversified agricultural policies have effectively improved both the yield and environmental performance of the crop sector. Quantifying productivity trends and their drivers is key to formulating strategies for high‐quality and low‐carbon crop development.
