Detecting Dengue in Flight: Leveraging Machine Learning to Analyze Mosquito Flight Patterns for Infection Detection

Advanced Biology, EarlyView.
Dengue infection alters mosquito flight behavior, enabling detection using machine learning classifiers. This study analyzes 3D flight trajectories and evaluates multiple models, showing that longer sequence lengths improve classification performance.

Atomic‐Level Engineering of Synthetic Receptors for Enhanced Virus Detection and Removal

Advanced Healthcare Materials, EarlyView.
Advanced computational techniques are employed to design and optimize computationally designed imprinted receptors (CIRs) for virus detection and removal. CIR‐conjugated piezoelectric sensor achieves highly sensitive virus detection in water and human serum. CIR‐integrated membranes remove 100% of pathogenic viruses from contaminated water.

Light‐Harvesting Nanomaterials Based on Dyes for Energy Transfer and Amplified Biosensing

Advanced Materials, EarlyView.
Light harvesting (LH) in plants inspires researchers to develop artificial LH nanomaterials. Here, LH nanomaterials based on organic dyes are reviewed, considering fundamental challenges on aggregation‐caused quenching, excitation energy transfer, and exciton migration length.

Size of Outbreaks Near the Epidemic Threshold

, 2004
The spread of infectious diseases near the epidemic threshold is investigated. Scaling laws for the size and the duration of outbreaks originating from a single infected individual in a large susceptible population are obtained.
