Sea ice concentration estimation via physical information-guided multi-source data fusion and spatial continuity preservation

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
Arctic sea ice concentration (SIC) serves as a key geophysical parameter for monitoring sea ice variability and constraining numerical weather and climate models.

Metasurface‐Enabled Active‐Like Passive Radar

open access: yesAdvanced Science, EarlyView.
A programmable space‐time‐coding metasurface embeds distinct spatiotemporal tags into ambient wireless signals, allowing passive radar to operate in an active‐like manner. By enabling code‐correlated reconstruction under interference, the approach supports robust real‐time UAV tracking in complex environments and points to intelligent, low‐power ...

The Influence of Surface Sediment Presence on Observed Passive Microwave Brightness Temperatures of First-Year Sea Ice during the Summer Melt Period

open access: yesCanadian Journal of Remote Sensing, 2019
Knowledge on the influence of sea ice sediment on passive microwave brightness temperatures (TB) is currently limited, leading to potential inaccuracies in derived sea ice concentrations where this ice exists. We propose that sediment may influence TB in

Beyond Percolation: Graphene‐Enabled Network Reinforcement Enhances Thermal Transport in Paraffin Phase‐Change Composites

open access: yesAdvanced Science, EarlyView.
Expanded‐graphite/graphene‐nanoplatelet hybrids deliver a near‐order‐of‐magnitude thermal‐conductivity enhancement in paraffin phase‐change materials. A microCT‐informed 3D modeling framework resolves the percolating EG backbone and captures sub‐voxel GNP enrichment, quantitatively linking microstructure to heat flow and revealing a graphene‐enabled ...

Heat Shock Protein 90: From Molecular Chaperone Function to Therapeutic Targeting in Malignancies

open access: yesAdvanced Science, EarlyView.
In this review, an integrated conceptual framework linking HSP90's molecular chaperone functions to its pathological roles in cancer is proposed. HSP90 serves as a central node that integrates oncogenic signaling, buffers proteotoxic stress, maintains cancer stem cell plasticity, and shapes tumor‐immune interactions, all of which converge to drive ...

Enhancing Blood Circulation With Epsilon‐Near‐Zero (ENZ) Materials via the Far‐Infrared Window of Human Skin

open access: yesAdvanced Science, EarlyView.
Epsilon‐near‐zero (ENZ) silicon carbide enables a selective far‐infrared emitter spectrally aligned with the human skin window around 10 µm for wavelength‐matched thermal therapy. In 25 within‐subject trials (50 hands) monitored by laser speckle contrast imaging, SiC increases blood perfusion by 30.2% versus a broadband graphite emitter while ...
