BESA: Boosting Encoder Stealing Attack with Perturbation Recovery
To boost the encoder stealing attack under the perturbation-based defense that hinders the attack performance, we propose a boosting encoder stealing attack with perturbation recovery named BESA. It aims to overcome perturbation-based defenses. The core of BESA consists of two modules: perturbation detection and perturbation recovery, which can be combined with canonical encoder stealing attacks. The perturbation detection module utilizes the feature vectors obtained from the target encoder to …

Post-inflationary enhancement of adiabatic perturbations in modular cosmology
We show that multi-field inflationary models with negligible turning in field space during inflation can lead to an effective sourcing of adiabatic from entropic perturbations {\it after} the end of inflation. We illustrate this general phenomenon with a detailed analysis of an inflationary model whose scalar potential is determined by modular invariance. Its entropic perturbations are frozen during inflation, but instead, they are converted into adiabatic perturbations in the first post-inflat…

Inflaton perturbations through an Ultra-Slow Roll transition and Hamilton-Jacobi attractors
We examine the behaviour of the gauge invariant scalar field perturbations in an analytic inflationary model that transitions from slow roll to an ultra-slow roll (USR) phase. We find that the numerical solution of the Mukhanov-Sasaki equation is well described by Hamilton-Jacobi (HJ) theory, as long as the appropriate branches of the Hamilton-Jacobi solutions are invoked: Modes that exit the horizon during the slow roll phase evolve into the USR as described by the first HJ branch, up to a sub…

On the nodal domain count under metric perturbations, Courant sharpness and boundary intersections
In this note, we investigate the effects of metric perturbations of closed surfaces on the number of nodal domains. In particular, we show that the nodal domain count for Laplace eigenfunctions is (locally) maximised for non-generic metrics. We also investigate localised perturbations and showcase some interesting applications regarding Courant sharp metrics on closed surfaces and associated boundary nodal-data prescription problems.
