Optimizing the topological properties of stacking semiconductor-ferromagnet-superconductor heterostructures

Kavli Affiliate: Michael Wimmer | First 5 Authors: Chun-Xiao Liu, Michael Wimmer, , , | Summary: We study the electronic properties of a planar semiconductor-superconductor heterostructure, in which a thin ferromagnetic insulator layer lies in between and acts as a spin filtering barrier. We find that in such a system one can simultaneously enhance the […]

Integrated optical-readout of a high-Q mechanical out-of-plane mode

Kavli Affiliate: Simon Groblacher | First 5 Authors: Jingkun Guo, Simon Gröblacher, , , | Summary: The rapid development of high-Q macroscopic mechanical resonators has enabled great advances in optomechanics. Further improvements could allow for quantum-limited or quantum-enhanced applications at ambient temperature. Some of the remaining challenges include the integration of high-Q structures on a […]

OctAttention: Octree-based Large-scale Contexts Model for Point Cloud Compression

Kavli Affiliate: Wei Gao | First 5 Authors: Chunyang Fu, Ge Li, Rui Song, Wei Gao, Shan Liu | Summary: In point cloud compression, sufficient contexts are significant for modeling the point cloud distribution. However, the contexts gathered by the previous voxel-based methods decrease when handling sparse point clouds. To address this problem, we propose […]

Multi-direction and Multi-scale Pyramid in Transformer for Video-based Pedestrian Retrieval

Kavli Affiliate: Wei Gao | First 5 Authors: Xianghao Zang, Ge Li, Wei Gao, , | Summary: In video surveillance, pedestrian retrieval (also called person re-identification) is a critical task. This task aims to retrieve the pedestrian of interest from non-overlapping cameras. Recently, transformer-based models have achieved significant progress for this task. However, these models […]

Universal catastrophe time distributions of dynamically unstable polymers

Kavli Affiliate: Ariel Amir | First 5 Authors: Paul B. Dieterle, Jenny Zheng, Ethan Garner, Ariel Amir, | Summary: Dynamic instability — the growth, catastrophe, and shrinkage of quasi-one-dimensional filaments — has been observed in multiple biopolymers. Scientists have long understood the catastrophic cessation of growth and subsequent depolymerization as arising from the interplay of […]

Tube-Balloon Logic for the Exploration of Fluidic Control Elements

Kavli Affiliate: George M. Whitesides | First 5 Authors: Jovanna A. Tracz, Lukas Wille, Dylan Pathiraja, Savita V. Kendre, Ron Pfisterer | Summary: The control of pneumatically driven soft robots typically requires electronics. Microcontrollers are connected to power electronics that switch valves and pumps on and off. As a recent alternative, fluidic control methods have […]

Memory Defense: More Robust Classification via a Memory-Masking Autoencoder

Kavli Affiliate: Dan Luo | First 5 Authors: Eashan Adhikarla, Dan Luo, Brian D. Davison, , | Summary: Many deep neural networks are susceptible to minute perturbations of images that have been carefully crafted to cause misclassification. Ideally, a robust classifier would be immune to small variations in input images, and a number of defensive […]
