Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes
Advanced Materials, EarlyView.Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Beamforming Design for Secure RIS-Enabled ISAC: Passive RIS vs. Active RIS
The forthcoming sixth-generation (6G) communications standard is anticipated to provide integrated sensing and communication (ISAC) as a fundamental service. These ISAC systems present unique security challenges because of the exposure of information-bearing signals to sensing targets, enabling them to potentially eavesdrop on sensitive communication ...

Ri-creare la storia per Ri-generare
And, 2021 In the immediate present, a regenerative act, besides the help of “decision support systems” like Kassandra, consists in preserving and defending the History of a place from degenerative events in the urban space, as it was for the action of the so-called “red weevil” (Rhynchophorus ferrugineus) on the existing palm trees.
