Resonances of the Frobenius-Perron Operator for a Hamiltonian Map with a Mixed Phase Space
, 2001 Resonances of the (Frobenius-Perron) evolution operator P for phase-space densities have recently attracted considerable attention, in the context of interrelations between classical and quantum dynamics.

First time description of dismantling phenomenon [PDF]
, 2015 International audienceDismantling is a complex psychic phenomenon, which is not easy to define, and little interest has been shown in the subject. The authors of this paper want to demonstrate that dismantling is the main defense mechanism in autism ...

Layer‐Wise Cue Alignment for Unified Face Attack Detection With Vision‐Language Model
IET Biometrics, Volume 2025, Issue 1, 2025.Unified face attack detection (UAD), which simultaneously addresses physical presentation attacks (PAs) and digital forgery attacks (DAs) with a vision‐language model, remains challenging due to the difficulty of effectively separating live and fake cues.

Cancellation for $(G,n)$-complexes and the Swan finiteness obstruction
, 2020 In previous work, we related homotopy types of $(G,n)$-complexes when $G$ has periodic cohomology to projective $\mathbb{Z} G$ modules representing the Swan finiteness obstruction.

Frobenius-Perron Resonances for Maps with a Mixed Phase Space
, 2001 Resonances of the time evolution (Frobenius-Perron) operator P for phase space densities have recently been shown to play a key role for the interrelations of classical, semiclassical and quantum dynamics.

Facial Emotion Recognition Method Based on Convolutional Neural Network
IET Computers &Digital Techniques, Volume 2025, Issue 1, 2025.Facial emotion recognition has poor robustness and low recognition accuracy in complex lighting, posture changes, and occlusion scenes. This study aims to design a high‐performance convolutional neural network (CNN) model to improve the recognition accuracy and generalization ability of seven basic emotions in complex environments.

Removing the anonymity axiom in assessing pro-poor growth [PDF]
, 2005 The recent focus on 'pro-poor growth' led also to an intense debate on how exactly to define and to measure pro-poor growth. However, all suggested measures, irrespective whether they use the absolute or the relative definition of pro-poor growth have in

Face Liveness Detection by rPPG Features and Contextual Patch-Based CNN [PDF]
Proceedings of the 2019 3rd International Conference on Biometric Engineering and Applications, 2019 Face anti-spoofing plays a vital role in security systems including face payment systems and face recognition systems. Previous studies showed that live faces and presentation attacks have significant differences in both remote photoplethysmography (rPPG) and texture information, we propose a generalized method exploiting both rPPG and texture features

IET Image Processing, Volume 19, Issue 1, January/December 2025.This paper proposes a palmprint image processing algorithm based on grey‐level co‐occurrence matrix and attention mechanism to extract deception patterns in fake images. Extensive experiments against several state‐of‐the‐art algorithms in closed‐set, open‐set and cross‐domain recognition settings validate the effectiveness of the proposed algorithm ...
