Nonexistence of invariant measures [PDF]
Proceedings of the American Mathematical Society, 1983 Let G G be a group acting on a set X X . Suppose that for some positive integer r r , G G contains a free group F F of rank > r > r and the intersection of any stabilizer with F F has rank ⩽

Electronic Journal of Qualitative Theory of Differential Equations, 2015 We obtain results on nonexistence of nontrivial nonnegative solutions for some elliptic and parabolic inequalities with functional parameters involving the $p(x)$-Laplacian operator. The proof is based on the test function method.

Agribusiness, EarlyView.Abstract Nucleus outgrower schemes are contractual arrangements where well‐resourced large‐scale farmers (nucleus farmers) are empowered by development support agencies to take charge of smallholder farmers, by providing them with market access and the necessary training on agronomic practices and farm inputs for production.

Advanced Intelligent Discovery, EarlyView.Combining machine learning and probabilistic statistical learning is a powerful way to discover and design new materials. A variety of machine learning approaches can be used to identify promising candidates for target applications, and causal inference can help identify potential ways to make them a reality.

Advanced Intelligent Systems, EarlyView.FTGRN introduces an LLM‐enhanced framework for gene regulatory network inference through a two‐stage workflow. It combines a Transformer‐based model, pretrained on GPT‐4 derived gene embeddings and regulatory knowledge, with a fine‐tuning stage utilizing single‐cell RNA‐seq data.

Electronic Journal of Differential Equations, 2011 We obtain the existence and multiplicity of positive $T$-periodic solutions for the difference equations $$ Delta x(n)=a(n,x(n))-lambda b(n)f(x(n-au(n))) $$ and $$ Delta x(n)+a(n,x(n))=lambda b(n)f(x(n-au(n))), $$ where $f(cdot)$ may be singular
