A Fractional Differential Equation Model for Energy-Aware Trust-Based Security in Mobile-Agent Wireless Sensor Networks

This paper proposes a Caputo fractional differential equation model that couples residual energy, trust, and compromise probability to analyze how the fractional order's memory parameter influences the trade-off between security responsiveness and energy conservation in mobile-agent wireless sensor networks, demonstrating that while fractionalization alters transient dynamics under burst attacks, it does not intrinsically enhance security.

Extended Reasoning Mode Improves Large Language Model Accuracy on the Orthopaedic In-Training Examination: A Paired Within-Model Comparison

This study demonstrates that utilizing extended-reasoning inference significantly improves GPT-5's accuracy on Orthopaedic In-Training Examination questions compared to standard mode, though the persistence of confident errors suggests these models should serve as supervised adjuncts rather than primary study resources for residents.

Deep Learning for Automated Tic Detection and Prediction in Tourette Syndrome Using Electromyography and Video

This study demonstrates that while short-term signal dynamics are crucial for predicting tics in Tourette syndrome, longer 5-second temporal windows combined with temporal CNNs significantly enhance the detection of motor tics from EMG data, highlighting the need for multimodal integration and patient-specific modeling in future research.
