Double sequence spaces extend the classical notion of sequence spaces to encompass two-indexed structures, thereby providing a robust framework for the analysis of functions and operators in ...

In a recent study posted to the bioRxiv* preprint server, researchers assessed the impact of evolutionary convergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) A-lineage ...

Only some bats and toothed whales rely on sophisticated echolocation, in which they emit sonar pulses and process returning echoes, to detect and track down small prey. Now, two new studies show that ...

Let X, Y be two sequence spaces defined by speeds of the convergence, i.e.; by monotonically increasing positive sequences. In this paper, we give necessary and sufficient conditions for a matrix A ...

The influenza observation, together with MindWalk's previously disclosed HYFT-enabled dengue epitope program, shows HYFT as a cross-pathogen platform for identifying conserved functional design rules ...
