Light can be squeezed by reducing the quantum uncertainty of the electric field for some phases. We show how to use this purely-quantum effect to extract net mechanical work from radiation pressure in a simple quantum photon engine. Along the way, we

Recent studies have revealed that vision-language (VL) models are vulnerable to adversarial attacks for image-text retrieval (ITR). However, existing defense strategies for VL models primarily focus on zero-shot image classification, which do not con

Intelligent tutoring systems optimize the selection and timing of learning materials to enhance understanding and long-term retention. This requires estimates of both the learner's progress (''knowledge tracing''; KT), and the prerequisite structure

The breakdown voltage of silicon sensors without special surface is known to be affected by the ambient humidity. To understand the sensor's humidity sensitivity, Synopsys TCAD was used to simulate n-in-p test structures for different effective relat
