Deep Fusion: A High‐Performance AI Framework for Colorectal Cancer Grading
ABSTRACT Automated, precise histopathological grading of colorectal cancer (CRC) is vital for prognosis and treatment but is challenged by inter‐observer variability and time demands. This study introduces and evaluates a novel deep learning framework for robust four‐class grading of colorectal adenocarcinoma (Normal, Well, Moderately, and Poorly ...

Entanglement in Quantum Systems Based on Directed Graphs
The entanglement properties of quantum states associated with directed graphs are investigated. It is proved that the vertex degree distribution fully determines this entanglement measure, which remains invariant under vertex relabeling, thereby highlighting its topological character.

Phase‐Changing Vanadium Oxides for Electromagnetic Radiation Management
Vanadium dioxide's reversible insulator‐to‐metal transition near room temperature enables ultrafast, broadband electromagnetic modulation from ultraviolet to radiofrequencies. With femtosecond switching speeds and cycling endurance exceeding 100 million cycles, VO2 metasurfaces achieve tuneable absorption, beam steering, and polarisation control. These

Communication‐Security Co‐Design for Federated Learning in Grant‐Free NOMA IoT Networks
This article presents SA‐PPO, a Security‐Aware Proximal Policy Optimisation framework for federated learning over grant‐free NOMA (non‐orthogonal multiple access) in IoT networks. By jointly optimising access control, resource allocation, and trust‐weighted aggregation using cross‐layer indicators, SA‐PPO enhances both communication reliability and ...

This paper proposes a novel malware propagation model based on epidemiological theory, specifically tailored for hierarchically protected wireless sensor networks (WSNs). We classify nodes into strongly and weakly protected categories and establish a four‐state propagation dynamics model (susceptible, exposed, infected, and recovered) to simulate ...

The charging station (CS) plays a crucial role in charging electric vehicles. Therefore, it is necessary to protect the CS from cyberattacks. This paper proposes an architecture for the security of the EV fleet during charging using the XGBoost model and Hyperledger Fabric to protect battery management systems (BMS) from cyberattacks.

(Not Surprising) Attacks on Recent Pairing‐Free Attribute‐Based Encryption Schemes
The fact that designing secure and efficient identity or attribute‐based encryption (ABE) schemes requires the use of specific algebraic tools like bilinear pairings or lattices is well known in the cryptographic community. However, some journals whose main topics are not cryptographic still publish papers proposing, for instance, ABE schemes in ...
