CS-SHRED: enhancing SHRED for robust recovery of spatiotemporal dynamics

Abstract We present CS-SHRED, a novel deep learning architecture that integrates compressed sensing (CS) into a shallow recurrent decoder (SHRED) to reconstruct spatiotemporal dynamics from incomplete, compressed or corrupted data. Our approach introduces two key innovations. Fir...

Reconfiguring University Missions in the Knowledge Society: The Case of Portuguese Universities in European Alliances

ABSTRACT This paper examines how European Knowledge Society policy scripts, amplified by the European Universities initiative, are appropriated in the strategic plans of Portuguese public universities. Focusing on nine universities participating in European Universities Alliances...

Application of the Hirshfeld Atom Refinement to Determine the Spin State of the Novel Fe(III) Schiff Base Complex

The novel complex [FeIII(HL)(L)]·2dmf (1) was successfully synthesized by reacting iron chloride with dimethylformamide solution of the Schiff base ligand (H2L). The ligand was prepared in situ through the condensation of 5-bromo-salicylaldehyde and benzhydrazide. The compound 1...

Mixed-Variable Optimisation as a Metric Product Space: Transient Categorical Geometry and a Hierarchy of Local Optimality

v2, August 2026: substantially revised version — restructured into eight sections, renamed optimality hierarchy (single-ordering / visited-orderings / all-orderings), corrected algorithmic section, and a new controlled computational experiment. A version of this manuscript is und...
