Advanced Science, EarlyView.By profiling the spatiotemporal hepatic landscape of CHB mouse models, the originally peri‐portal localized KCs migrated to the peri‐central in a CXCL9‐CXCR3‐dependent manner, facilitating their interaction with HBV+ hepatocytes. The interaction promoted LMD in KCs through ASGR1‐induced LXRα degradation, which, in turn, induced CSC formation via Stat3 ...

Advanced Science, EarlyView.This work introduces a beamforming‐based method to generate acoustic images from fiber‐optic distributed acoustic sensing (DAS) data. By performing 2D scanning around the sensing fiber, the approach enables near‐field imaging and localization of acoustic sources, even in regions distant from the fiber. A data‐driven DAS channel selection improves image

Slope Estimation from ICESat/GLAS
Remote Sensing, 2014 We present a novel technique to infer ground slope angle from waveform LiDAR, known as the independent slope method (ISM). The technique is applied to large footprint waveforms (\(\sim\) mean diameter) from the Ice, Cloud and Land Elevation Satellite ...

High‐Speed, Maneuverable, and Terrain‐Adaptive Micro‐Robot with Tree Frog‐Inspired Bionic Feet
Advanced Science, EarlyView.A 7.5 mm micro‐robot integrates tree frog‐inspired bionic feet with an electromagnetic linear motor to achieve high‐speed locomotion, slope climbing, and precise turning. It reaches 39 body lengths per second and ascends 30° slopes. The system demonstrates strong potential for inspection tasks in confined and complex environments, such as micro‐aero ...

Stratigraphy of the Perrine and Nun Sulci quadrangles (Jg-2 and Jg-5), Ganymede [PDF]
Dark and light terrain materials in the Perrine and Nun Sulci quadrangles are divided into nine map units, four dark, and five light. These are placed in time-stratigraphic sequence primarily by means of embayment and cross-cutting relationships.

Advanced Science, EarlyView.A novel strategy is developed by doping reduced graphene oxide (rGO) into a (HfZrTi)C medium‐entropy ceramic. This induces a hierarchical strain modification mechanism, synergistically inhibiting crack propagation at the microscale and dissipating stress at the mesoscale.

The Lay of the Land: Sensing and Representing Topography
The Baltic International Yearbook of Cognition, Logic and Communication, 2015 Navigating, and studying spatial navigation, is difficult enough in two dimensions when maps and terrains are flat. Here we consider the capacity for human spatial navigation on sloped terrains, and how sloping terrain is depicted in 2D map ...

Implications of Viking color data for evolution of the Amenthes Region, Mars [PDF]
In the Eastern Hemisphere of Mars, where the hemispheric dichotomy is not overlain by relatively recent flows from the Tharsis volcanoes, the Mars cratered terrain boundary (CTB) now exists as highly fractured terrain juxtaposed with the smooth plains of

Advanced Science, EarlyView.Electrospinning a composite of PVDF, HfO2, and nano‐Cu transforms the discrete precursors into a continuous nanofiber mesh, forming a multi‐interface heterostructure with embedded nanoparticles. The presence of HfO2 and nano‐Cu at the fiber interfaces induces a highly aligned β‐phase, which enhances piezoelectric crystallinity and improves the material'

Assessing the Value of UAV Photogrammetry for Characterizing Terrain in Complex Peatlands
Remote Sensing, 2017 Microtopographic variability in peatlands has a strong influence on greenhouse gas fluxes, but we lack the ability to characterize terrain in these environments efficiently over large areas.
