Semilinear elliptic boundary-value problems on bounded multiconnected domains
A semilinear elliptic boundary-value problem on bounded multiconnected domains is studied. The authors prove that under suitable conditions, the problem may have no solutions in certain cases and many have one or two nonnegative solutions in some other ...

Complexity of the Directed Robust b‐Matching Problem and Its Variants on Different Graph Classes
ABSTRACT The b$$ b $$‐matching problem is a well‐known generalization of the classical matching problem with various applications in operations research and computer science. Given an undirected graph, each vertex v$$ v $$ has a capacity bv$$ {b}_v $$, indicating the maximum number of times it can be matched, while edges can also be used multiple times.

On periodic solutions of second-order partial difference equations involving p-Laplacian
By combining variational techniques with the saddle point theorem, we investigate the existence and nonexistence of periodic solutions to second-order partial difference equations involving p-Laplacians.

Analysis of IDH1 and IDH2 mutations as causes of the hypermethylator phenotype in colorectal cancer
Abstract The CpG island methylator phenotype (CIMP) occurs in many colorectal cancers (CRCs). CIMP is closely associated with global hypermethylation and tends to occur in proximal tumours with microsatellite instability (MSI), but its origins have been obscure.

We study the nonexistence of nontrivial solutions for the nonlinear elliptic system $$\displaylines{ G_{\alpha,\beta,\theta}(u^{p},u^{q}) = v^{r}\cr G_{\lambda,\mu,\theta}(v^{s},v^{t}) = u^{m}\cr u,v\geq 0, }$$ where $0q\geq p\geq 1$, $r>t\geq s\
