Synergistic Spin‐Polarization and Single‐Atom Engineering in Magnetic Heterojunctions for Efficient Solar Water Splitting

Advanced Science, EarlyView.
High‐throughput screening led to the identification of 67 Z‐scheme heterojunctions (comprising 2D magnetic transition metal halides and non‐magnetic transition metal chalcogenides). For CrI3/MoTe2 and CrI3/WTe2, electronic structure analysis demonstrated that synergistic crystallographic point group and built‐in electric field effects generate a ...

Symmetry‐Driven Unconventional Magnetoelectric Coupling in Perovskite Altermagnets: From Bulk to the Two‐Dimensional Limit

Advanced Science, EarlyView.
The symmetry‐driven coexistence of altermagnetism and (anti)ferroelectricity in perovskites shows a strong dimensional dependence. Upon reducing the system from bulk to the two‐dimensional limit, only C‐type antiferromagnetic order retains ferroelectrically switchable altermagnetism, whereas A‐ and G‐type orders become conventional antiferromagnets ...

Quantum vs post‐quantum security for future networks: Survey

Cyber Security and Applications
Classical cryptography (crypt) schemes (sche) have been compromised by the practical results on quantum (q) computers in recent years. Nowadays these sche ‘s can be compromised by using the Shor's methodology. This paper provides a detailed survey of the

Ferroelectric Devices for In‐Memory and In‐Sensor Computing

Advanced Science, EarlyView.
Inspired by biological systems, in‐memory and in‐sensor computing overcome von Neumann bottlenecks. Ferroelectric devices can mimic synaptic functions and sense stimuli like light or force, therefore are ideal for these paradigms. This review introduces the ferroelectric devices applied for in‐memory and in‐sensor computing, covering their structures ...

Synchronization‐Dissipation in the Cardiorespiratory System

Advanced Science, EarlyView.
By modeling central nervous coupling and viscoelastic interactions in the cardiorespiratory system we show that synchronization produces a 10% gain in cardiac efficiency in humans. It is surmised that respiratory sinus arrhythmia improves cardiac pumping efficiency by reducing dynamic stress and power dissipation in the pulmonary vasculature.

Standardisation of and Migration to Post-Quantum Cryptography

Abstract Recent reports on the timeline of quantum threats suggest that large, scalable quantum computers will likely become a reality in the near future. This impending technological advancement has increased the urgency for standardisation of and migration to Post-Quantum Cryptography (PQC), making it a critical focus for information and ...

Quantum-Secure Timestamp for the Integrity of Classical Signatures in Quantum Transition

IEEE Access
As the development of quantum computers becomes a reality, concerns about the security of classical cryptography are growing. In the case of signature schemes, integrity must be guaranteed for a sufficient period of time after their generation.
