Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Joel Guo, Charles A. McLemore, Chao Xiang, Dahyeon Lee, Lue Wu | Summary: Lasers with hertz-level linewidths on timescales up to seconds are critical for precision metrology, timekeeping, and manipulation of quantum systems. Such frequency stability typically relies on bulk-optic lasers and reference cavities, where increased […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiaotian Li, Xiang Zhang, Taoyue Wang, Lijun Yin, | Summary: Recent studies on the automatic detection of facial action unit (AU) have extensively relied on large-sized annotations. However, manually AU labeling is difficult, time-consuming, and costly. Most existing semi-supervised works ignore the informative cues from the temporal […]
Kavli Affiliate: Chiara Daraio | First 5 Authors: Semih Taniker, Vincenzo Costanza, Paolo Celli, Chiara Daraio, | Summary: We propose the realization of capacitive temperature sensors based on the concept of displacement amplification. Our design features two high coefficient of thermal expansion (CTE) metallic layers separated by a low-CTE dielectric layer; conductive and dielectric layers […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiaotian Li, Xiang Zhang, Huiyuan Yang, Wenna Duan, Weiying Dai | Summary: Emotion is an experience associated with a particular pattern of physiological activity along with different physiological, behavioral and cognitive changes. One behavioral change is facial expression, which has been studied extensively over the past few […]
Kavli Affiliate: Joel E. Moore | First 5 Authors: Michał Papaj, Joel E. Moore, , , | Summary: In most superconductors, optical excitations require impurity scattering or the presence of multiple bands. This is because in clean single-band superconductors, the combination of particle-hole and inversion symmetries prevents momentum-conserving transitions. In this work we show how […]
Kavli Affiliate: L. Mahadevan | First 5 Authors: Salem al-Mosleh, L. Mahadevan, , , | Summary: Growing a flat lamina such as a leaf is almost impossible without some feedback to stabilize long wavelength modes that are easy to trigger since they are energetically cheap. Here we combine the physics of thin elastic plates with […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Changhao Wang, Yuyou Zhang, Xiang Zhang, Zheng Wu, Xinghao Zhu | Summary: Manipulating deformable linear objects by robots has a wide range of applications, e.g., manufacturing and medical surgery. To complete such tasks, an accurate dynamics model for predicting the deformation is critical for robust control. In […]
Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Qianbiao Liu, Lijun Zhu, Xiyue S. Zhang, David A. Muller, Daniel C. Ralph | Summary: Efficient manipulation of antiferromagnetically coupled materials that are integration-friendly and have strong perpendicular magnetic anisotropy (PMA) is of great interest for low-power, fast, dense magnetic storage and computing. Here, we report […]
Kavli Affiliate: Sunil Golwala | First 5 Authors: Peter S. Barry, Clarence. C. Chang, Sunil Golwala, Erik Shirokoff, | Summary: The kinetic inductance detector (KID) is a versatile and scalable detector technology with a wide range of applications. These superconducting detectors offer significant advantages: simple and robust fabrication, intrinsic multiplexing that will allow thousands of […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Lei Yu, , , | Summary: Slow shutter speed and long exposure time of frame-based cameras often cause visual blur and loss of inter-frame information, degenerating the overall quality of captured videos. To this end, we present a unified framework of event-based motion deblurring and […]
