Continual Learning for Multimodal Data Fusion of a Soft Gripper

open access: yesAdvanced Robotics Research, EarlyView.
Models trained on a single data modality often struggle to generalize when exposed to a different modality. This work introduces a continual learning algorithm capable of incrementally learning different data modalities by leveraging both class‐incremental and domain‐incremental learning scenarios in an artificial environment where labeled data is ...

Photonic Time Crystals and Time‐Varying Electromagnetic Metamatter: A New Direction for Ultrafast Tunable Photonic and Microwave Materials and Devices

open access: yesAdvanced Science, EarlyView.
Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...

The Seasonality of Conflict

open access: yesConflict Management and Peace Science, 2020
This paper uses one of the largest changes to labor demand in developing countries—harvest—to examine how the returns to fighting vs. working impact the intensity of conflict. Exploiting the exogenous allocation and timing of harvest across Afghanistan, Iraq, and Pakistan, we find that the onset of harvest reduces the number of insurgent attacks by ...
