Motion Parameter Estimation of Doppler-Ambiguous Moving Targets in SAR-GMTI [PDF]
, 2007 In an along-track interferometric SAR system, the discrete sampling of moving target signals can give rise to two types of ambiguity: Doppler ambiguity, and interferometric angle ambiguity.

Deltacoronavirus Modulates circRNA cGLIS3 Metabolism to Evade Host Antiviral Response
Advanced Science, EarlyView.This study reveals that both deltacoronavirus nucleocapsid protein and host RNA binding protein IGF2BP2 promote circular RNA GLIS3 (cGLIS3) biogenesis by binding to GLIS3 pre‐mRNA. The m6A modification‐mediated cGLIS3‐IGF2BP2 interaction weakens RNase L‐mediated degradation of cGLIS3 while facilitates a ubiquitin‐dependent degradation of IGF2BP2, thus ...

Unveiling the Ultralow Thermal Conductivity of Hybrid Perovskites
Advanced Science, EarlyView.In hybrid perovskites, thermal energy flows through lattice vibrations of the framework (48%–65%) and organic molecules (35%–52%). When the disorder introduced by organic molecules is excluded, the temperature dependence of the vibrational thermal conductivity results from the lattice framework transits from ∼T0 to ∼T−1, and the value doubles at room ...

Differential Tissue‐Coupled Powering for Battery‐Free Injectable Electroceuticals
Advanced Science, EarlyView.A thread‐like injectable neural stimulator is powered through differential tissue‐coupled powering (DTCP), which harvests RF‐frequency tissue potentials with an elongated receiver while preserving a injectable cross‐section. The system integrates an ASIC, stimulation electrodes, and a portable transmitter, enabling wireless peripheral nerve stimulation,

Advanced Science, EarlyView.Stable radicals are attractive for photonic and quantum information technologies but are often limited by instability. We stabilize intrinsic radicals in graphene quantum dots via 2D polymerization of perylene derivatives, where bilayer defect confinement suppresses quenching (100–500 K).

Polarimetric Differential-TomoSAR Imaging [PDF]
, 2010 Recently, in parallel to the maturation of the operative InSAR techniques based on phase-only data, much interest has grown in techniques based on the coherent combination of SAR images at the complex (amplitude and phase) data level, for the extraction ...

Advanced Science, EarlyView.A nickel‐catalyzed three‐component reductive fluoroalkylation‐amination strategy of N‐vinylamides for the direct access to the α‐amidyl‐β‐difluoroalkyl amines was reported here. The synthetic method features with broad substrate scope, mild conditions, high functional group tolerance, and convenience to handle.
