Kavli Affiliate: Wei Gao | First 5 Authors: Xiangyu Yin, Xiangyu Yin, , , | Summary: Prosthetic legs play a pivotal role in clinical rehabilitation, allowing individuals with lower-limb amputations the ability to regain mobility and improve their quality of life. Gait analysis is fundamental for optimizing prosthesis design and alignment, directly impacting the mobility […]
Kavli Affiliate: Chiara Daraio | First 5 Authors: Alexander C. Ogren, Alexander C. Ogren, , , | Summary: Wave propagation on the surface of a material contains information about physical properties beneath its surface. We propose a method for inferring the thickness and stiffness of a structure from just a video of waves on its […]
Kavli Affiliate: Scott K. Cushing | First 5 Authors: Ayantika Sengupta, Ayantika Sengupta, , , | Summary: Compact, scalable, and multiplexed fluorescence lifetime sensors are of great interest for point-of-care diagnostics. However, current solutions either lack broad-range wavelength-tuning capabilities or involve complex optical setups that hinder miniaturization. On-chip entangled photon sources offer a promising alternative […]
Kavli Affiliate: Lihong V. Wang | First 5 Authors: Yushen Zuo, Yushen Zuo, , , | Summary: We present 4KAgent, a unified agentic super-resolution generalist system designed to universally upscale any image to 4K resolution (and even higher, if applied iteratively). Our system can transform images from extremely low resolutions with severe degradations, for example, […]
Kavli Affiliate: Lihong V. Wang | First 5 Authors: Peng Wang, Peng Wang, , , | Summary: Compressed ultrafast photography (CUP) is applied to laser breakdown in argon and xenon under pressures up to 40atm to obtain 2D images of the plasma dynamics of single events with a spatial resolution of 250×100 pixels and an […]
Kavli Affiliate: Wei Gao | First 5 Authors: Chen Gong, Bo Liang, Wei Gao, Chenren Xu, | Summary: Generative models have gained significant attention for their ability to produce realistic synthetic data that supplements the quantity of real-world datasets. While recent studies show performance improvements in wireless sensing tasks by incorporating all synthetic data into […]
Kavli Affiliate: Austin J. Minnich | First 5 Authors: Mete M. Bayrak, Mete M. Bayrak, , , | Summary: The high frequency performance and yield of III-V semiconductor devices such as InP HEMTs is negatively impacted by subsurface etch damage and non-uniform etch depth over the wafer. Atomic layer etching (ALE) has the potential to […]
Kavli Affiliate: Oskar Painter | First 5 Authors: Neha Mahuli, Neha Mahuli, , , | Summary: We present a dry surface treatment combining atomic layer etching and deposition (ALE and ALD) to mitigate dielectric loss in fully fabricated superconducting quantum devices formed from aluminum thin films on silicon. The treatment, performed as a final processing […]
Kavli Affiliate: Changhuei Yang | First 5 Authors: Ninghe Liu, Yu Xi Huang, Simon Mahler, Changhuei Yang, | Summary: Speckle contrast optical spectroscopy (SCOS) offers a non-invasive and cost-effective method for monitoring cerebral blood flow (CBF). However, extracting accurate CBF from SCOS necessitates precise noise pre-calibration. Errors from this can degrade CBF measurement fidelity, particularly […]
Kavli Affiliate: Morteza Gharib | First 5 Authors: Ioannis Mandralis, Richard M. Murray, Morteza Gharib, , | Summary: Quadrotor Morpho-Transition, or the act of transitioning from air to ground through mid-air transformation, involves complex aerodynamic interactions and a need to operate near actuator saturation, complicating controller design. In recent work, morpho-transition has been studied from […]
