Doppler Shift and SFO Robust Synchronization for LoRa-Like Acoustic Underwater Communication

IEEE Access, 2023
Frequency shift chirp modulation (FSCM) is the modulation technique utilized by the LoRa physical layer, a widely used and relatively new communication technique for radio low-power wide area networks (LPWANs).

Gardening Cyber-Physical Systems [PDF]

, 2012
Today's artefacts, from small devices to buildings and cities, are, or are becoming, cyber-physical socio-technical systems, with tightly interwoven material and computational parts. Currently, we have to laboriously build such systems, component by component, and the results are often difficult to maintain, adapt, and reconfigure.

Temperature‐Resilient Reconfigurable Physical Unclonable Function Driven by Pulse Modulation Using CMOS‐Integrated Spintronic Chips

Advanced Science, EarlyView.
A reconfigurable physical unclonable function is developed using CMOS‐integrated SOT‐MRAM chips, leveraging a dual‐pulse strategy and offering enhanced environmental robustness. A temperature‐compensation effect arising from the CMOS transistor and SOT‐MTJ is revealed and established as a key prerequisite for thermal resilience.

Selective Interfacial Barriers Drive High‐Performance GeTe Thermoelectrics

Advanced Science, EarlyView.
Carrier‐phonon decoupling is the key to developing high‐performance thermoelectric materials. Here, we demonstrate that selective interfacial barriers can decouple carrier and phonon transport, thus achieving an exceptional peak ZT of ∼2.7 at 773 K, along with a record‐high average ZT of 1.9 across 300–773 K in the (Ge0.82Mn0.04Bi0.04Pb0.1Te)0.99(VSe2 ...

Mechanistic Understanding of Protein–MOF Integration Through Surfactant‐Driven Interfacial Design

Advanced Science, EarlyView.
This study reveals how surfactant‐driven interfacial design governs the assembly and stability of protein@MOF composites. Using lipid‐based nonionic surfactants, we modulate protein–MOF interactions to improve encapsulation efficiency, MOF crystallization, and catalytic performance.

Causality for Cyber-Physical Systems

CoRR
We present a formal theory for analysing causality in cyber-physical systems. To this end, we extend the theory of actual causality by Halpern and Pearl to cope with the continuous nature of cyber-physical systems. Based on our theory, we develop an analysis technique that is used to uncover the causes for examples of failures resulting from ...
