Kavli Affiliate: Sara Seager | First 5 Authors: Jane S. Greaves, Paul B. Rimmer, Anita M. S. Richards, Janusz J. Petkowski, William Bains | Summary: New analysis is presented of the 1.1 mm wavelength absorption lines in Venus’ atmosphere that suggested the presence of phosphine. We retrieve a sulphur dioxide observation from the JCMT archive […]
Kavli Affiliate: Laura Schaefer | First 5 Authors: Laura Schaefer, Vivien Parmentier, , , | Summary: Atmospheric compositions for rocky exoplanets will depend strongly on the bulk planetary composition and the orbital position of the planet. Non-traditional gases may be present in the atmospheres of exceptionally hot planets. Atmospheres of more clement planets will depend […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Ziyu Liu, Xiang Zhang, , , | Summary: Electrocardiography (ECG) signal is a highly applied measurement for individual heart condition, and much effort have been endeavored towards automatic heart arrhythmia diagnosis based on machine learning. However, traditional machine learning models require large investment of time and effort […]
Kavli Affiliate: 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 the signal and reference paths, which results in random phase and amplitude […]

Kavli Affiliate: 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 propose a novel photonic transceiver architecture based on co-prime sampling techniques that […]

Kavli Affiliate: G. Ravichandran |Summary:Cell layers eliminate unwanted cells through the extrusion process, which underlines healthy versus flawed tissue behaviors. Although several biochemical pathways have been identified, the underlying mechanical basis including the forces involved in cellular extrusion remain largely unexplored. Utilizing a phase-field model of a three-dimensional cell layer, we study the interplay of […]
Kavli Affiliate: Tomoyuki Abe | Summary:In this paper, we show the non-existence of finitely generated integral $p$-adic cohomology which satisfies finite étale descent and the associated rational cohomology coincides with rigid cohomology. | Search Query: arXiv Query: search_query=au:”Abe Tomoyuki”&id_list=&start=0&max_results=10Read More
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 […]
