Cardiac MR: From Theory to Practice

Tevfik F. Ismail, Wendy Strugnell, Chiara Coletti, Maša Božić-Iven, Sebastian Weingärtner, Kerstin Hammernik, Teresa Correia, Thomas Küstner
2022 Frontiers in Cardiovascular Medicine  
Building blocks are illustrated to create an efficient and patient-centered workflow.  ...  Sequences containing these building blocks are formed for parametric mapping and functional imaging techniques.  ...  The results suggested that an efficient motion estimation network can bypass the need for high-quality reconstructions in order to achieve accurate image segmentation.  ...

FieldFuzz: In Situ Blackbox Fuzzing of Proprietary Industrial Automation Runtimes via the Network [article]

Andrei Bytes, Prashant Hari Narayan Rajput, Constantine Doumanidis, Nils Ole Tippenhauer, Michail Maniatakos, Jianying Zhou
2023 arXiv   pre-print
FieldFuzz leverages efficient network-based fuzzing based on three main contributions: i) reverse-engineering enabled remote control of control applications and runtime components, ii) automated command  ...  For example, remote code injection in a control application would directly allow to take over the PLC, threatening physical process damage and the safety of human operators.  ...  While fuzzing with the FRD, Ghost receives notification of Stalker dynamic recompilation events with their memory offsets indicating that a basic block is being executed.  ...
