Snapshot Spatiotemporal‐Spectral Imaging Enabled by Joint Photonic Encoding
Advanced Science, EarlyView.Spectra4D enables snapshot spatiotemporal‐spectral imaging by combining high‐speed DMD temporal modulation with CMOS‐integrated Fabry‐Pérot spectral encoding. From a single 2D measurement, a dual‐mask‐guided reconstruction network recovers multiple time‐resolved hyperspectral frames, enabling high‐fidelity observation of rapidly evolving spatial ...

Symbolic Graph Inference for Compound Scene Understanding
Scene understanding is a fundamental capability needed in many domains, ranging from question-answering to robotics. Unlike recent end-to-end approaches that must explicitly learn varying compositions of the same scene, our method reasons over their ...

Adaptive Active Illumination Via Translationally and Axially Tunable Cascaded Metasurfaces
Advanced Science, EarlyView.Active three‐dimensional sensing faces a fundamental trade‐off between seeing farther and covering more of the scene. Translationally and axially tunable cascaded metasurfaces overcome this limitation by continuously adapting beam direction and illumination coverage.

Data-Driven Scene Understanding from 3D Models
, 2018 In this paper, we propose a data-driven approach to leverage repositories of 3D models for scene understanding. Our ability to relate what we see in an image to a large collection of 3D models allows us to transfer information from these models, creating

Rethinking Cochlear Implants: The Need for Precise Temporal Coding
Advanced Science, EarlyView.Spatial hearing relies on sensitivity to interaural temporal cues, but this sensitivity is often poorly developed in patients with cochlear implants, particularly those with early‐onset hearing loss. Rats with cochlear implants, however, demonstrate excellent temporal sensitivity, suggesting that this limitation is not inevitable.

British Educational Research Journal, EarlyView., 2023 Abstract Early childhood has increasingly been acknowledged as a vital time for all children. Inclusive and quality education is part of the United Nations Sustainable Development Goals, with the further specification that all children have access to quality pre‐primary education.

Advanced Science, EarlyView.A transcriptionally distinct intermediate Langerhans cell state is identified between steady and migratory populations during skin injury. Integrated single‐cell transcriptomics, flow cytometry, and intravital imaging reveal state‐specific markers and implicate complement signaling, particularly C3, in regulating Langerhans cell accumulation near ...
