AbstractSuppose G is a group that splits as \(A*_C B\) or \(A*_C\), where A, B, C are relatively hyperbolic groups, the monomorphisms \(C\rightarrow A\) and \(C\rightarrow B\) are quasiisometric embeddings of pairs, and G is hyperbolic relative to a natural collection of subgroups. We show that C has finite relative height in G if and only if C is relatively quasiconvex in G.

AbstractDiverse microbial pathogens are known to attenuate host protein synthesis. Consequently, the host mounts a defense response against protein translation inhibition, leading to increased transcript levels of immune genes. The seemingly paradoxical upregulation of immune gene transcripts in response to blocked protein synthesis suggests that the defense mechanism against translation inhibition may not universally benefit host survival.

A source lying near a hyperbolic umbilic (HU) singularity leads to a ring-like image formation, constituting four images with high magnification factors and lying in a small region of the lens plane. Since (based on our earlier work) the observed number of HU image formations in cluster lenses is expected to increase in the future, it is timely to investigate them in more detail.
