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.

Gels for CO2 geo‐storage and conformance control: A systemic review of behavior and performance

Deep Underground Science and Engineering, Volume 4, Issue 4, Page 612-637, December 2025.
This review provides a systemic evaluation of potential sealants used in CO2 subsurface storage practices. Critical analyses of how external factors like CO2, pH, brine salinity and hardness, rock mineralogy, pressure, temperature, and injectivity could affect the performance of different sealants are provided. Abstract Carbon capture and storage (CCS)

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.

Coronary artery disease detection based on photoplethysmography via Gramian angular field transformation and deep learning

Journal of Intelligent Medicine, Volume 2, Issue 4, Page 169-178, December 2025.
Abstract Sudden cardiac death (SCD) remains one of the leading causes of mortality worldwide, with coronary artery disease (CAD) as its predominant underlying condition. However, noninvasive and accessible screening approaches for CAD are still limited.

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
