Kavli Affiliate: Wei Gao | First 5 Authors: Wei Gao, Jie Chen, Cédric Richard, Wentao Shi, Qunfei Zhang | Summary: The recursive least-squares algorithm with $ell_1$-norm regularization ($ell_1$-RLS) exhibits excellent performance in terms of convergence rate and steady-state error in identification of sparse systems. Nevertheless few works have studied its stochastic behavior, in particular its […]
Kavli Affiliate: Paul W. K. Rothemund | First 5 Authors: Tyler D. Ross, Dino Osmanović, John F. Brady, Paul W. K. Rothemund, | Summary: Snell’s law, which encompasses both refraction and total internal reflection, provides the foundation for ray optics and all lens-based instruments, from microscopes to telescopes. Refraction results when light crosses the interface […]
Kavli Affiliate: Paul W. K. Rothemund | First 5 Authors: Tyler D. Ross, Dino Osmanović, John F. Brady, Paul W. K. Rothemund, | Summary: Control of self-propelled particles is central to the development of many microrobotic technologies, from dynamically reconfigurable materials to advanced lab-on-a-chip systems. However, there are few physical principles by which particle trajectories […]
Kavli Affiliate: Ali Hajimiri | First 5 Authors: Aroutin Khachaturian, Reza Fatemi, Artsroun Darbinian, Ali Hajimiri, | Summary: A solid-state active beamformer based on the annular-ring diffraction pattern is proposed for an integrated photonic platform. Such a circularly symmetric annular-ring aperture achieves radiating element limited FOV. Furthermore, it is demonstrated that a multi-annular-ring aperture with […]
Kavli Affiliate: Andrei Faraon | First 5 Authors: Andrei Ruskuc, Chun-Ju Wu, Jake Rochman, Joonhee Choi, Andrei Faraon | Summary: Solid-state nuclear spins surrounding individual, optically addressable qubits provide a crucial resource for quantum networks, computation and simulation. While hosts with sparse nuclear spin baths are typically chosen to mitigate qubit decoherence, developing coherent quantum […]
Kavli Affiliate: Lihong Wang | First 5 Authors: Qian Li, Shu Guo, Jia Wu, Jianxin Li, Jiawei Sheng | Summary: Event extraction (EE), which acquires structural event knowledge from texts, can be divided into two sub-tasks: event type classification and element extraction (namely identifying triggers and arguments under different role patterns). As different event types […]
Kavli Affiliate: Ali Hajimiri | First 5 Authors: Aroutin Khachaturian, Reza Fatemi, Ali Hajimiri, , | Summary: Silicon photonics (SiP) integrated coherent image sensors offer higher sensitivity and improved range-resolution-product compared to direct detection image sensors such as CCD and CMOS devices. Previous generation of SiP coherent imagers suffer from relative optical phase fluctuations between […]
Kavli Affiliate: Ali Hajimiri | First 5 Authors: Aroutin Khachaturian, Reza Fatemi, Ali Hajimiri, , | Summary: Integrated photonic active beamforming can significantly reduce the size and cost of coherent imagers for LiDAR and medical imaging applications. In current architectures, the complexity of photonic and electronic circuitry linearly increases with the desired imaging resolution. We […]
Kavli Affiliate: Lihong Wang | First 5 Authors: Yiming Hei, Renyu Yang, Hao Peng, Lihong Wang, Xiaolin Xu | Summary: Android is undergoing unprecedented malicious threats daily, but the existing methods for malware detection often fail to cope with evolving camouflage in malware. To address this issue, we present HAWK, a new malware detection framework […]
Kavli Affiliate: Wei Gao | First 5 Authors: Shao-Qun Zhang, Wei Gao, Zhi-Hua Zhou, , | Summary: Complex-valued neural networks have attracted increasing attention in recent years, while it remains open on the advantages of complex-valued neural networks in comparison with real-valued networks. This work takes one step on this direction by introducing the emph{complex-reaction […]
