On constrained annealed bounds for pinning and wetting models
, 2005 The free energy of quenched disordered systems is bounded above by the free energy of the corresponding annealed system. This bound may be improved by applying the annealing procedure, which is just Jensen inequality, after having modified the ...

Journal of Mathematical Analysis and Applications, 2013 We develop a new framework for the Jensen-type inequalities that allows us to deal with functions not necessarily convex and Borel measures not necessarily positive.

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

Some bounds for skewed α-Jensen-Shannon divergence
Results in Applied Mathematics, 2019 Based on the skewed Kullback-Leibler divergence introduced in the natural language processing, we derive the upper and lower bounds on the skewed version of the Jensen-Shannon divergence and investigate properties of them.

Thermodynamics of quantum dissipative many-body systems
, 1999 We consider quantum nonlinear many-body systems with dissipation described within the Caldeira-Leggett model, i.e., by a nonlocal action in the path integral for the density matrix.

Size variation of an herbivorous insect affects host plant damage: Mechanisms behind the effect
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Intraspecific trait variation can strengthen or weaken species interactions in ecological communities. A mechanistic understanding of how intraspecific variation affects species interactions will help identify general rules about when intraspecific variation strengthens

From Place to Platform: Extended Global Cities Theory for Transnational Cultural Diffusion
British Journal of Management, EarlyView.Abstract This study investigates how global city characteristics shape the acceptance of non‐mainstream cultural goods—focusing on K‐pop—as they diffuse across digital platforms. While prior research emphasizes fandom, soft power or media strategies, this research highlights the role of urban infrastructure in cultural globalization.

Some New Improvements for Fractional Hermite–Hadamard Inequalities by Jensen–Mercer Inequalities
Journal of Function SpacesThis article’s objective is to introduce a new double inequality based on the Jensen–Mercer JM inequality, known as the Hermite–Hadamard–Mercer inequality. We use the JM inequality to build a number of generalized trapezoid-type inequalities.
