A weighted least squares solution for space intersection of spaceborne stereo SAR data [PDF]

open access: yes, 2001
The use of stereoscopic SAR images offers an alternative to interferometric SAR for the generation of digital elevation models (DEMs). The stereo radargrammetric method is robust and can generate DEMs of sufficient accuracy to geocode SAR images ...

Low Latency Global Carbon Budget Reveals Late 2024 Carbon Losses and Contrasting Early 2025 Land Sink Recovery Signals

open access: yesAdvanced Science, EarlyView.
Low latency carbon budget estimates for July 2024–June 2025 combine atmospheric CO2 growth rates, fossil emissions, ocean uptake, DGVM land fluxes, and OCO‐2 inversions. The budget shows that late‐2024 land carbon losses dominate the annual anomaly, while early‐2025 recovery differs between bottom‐up models and top‐down inversions, especially in ...

High‐Brightness and Ultra‐Long‐Lifetime Spin Quantum Dot Light‐Emitting Diodes Enabled by Efficient Injection of Spin‐Polarized Holes Through a Hybrid Hole Transport Layer

open access: yesAdvanced Science, EarlyView.
This work employs a hybrid hole transport layer to enhance hole transport efficiency, resulting in improved performance for the final device. It achieves an external quantum efficiency of 6.68%, a circularly polarized electroluminescence asymmetry factor of 0.026, and a high luminance of 14,370 cd/cm2, representing the highest luminance reported to ...

Revealing Temperature‐Driven Interfacial Reactions of Succinonitrile in PEO‒LiTFSI Electrolytes and Suppressing Them via Dual PEDOT‐Based Interfacial Layers

open access: yesAdvanced Science, EarlyView.
Temperature‐driven interfacial reactions of succinonitrile in PEO‐LiTFSI electrolyte are revealed at both lithium and cathode interfaces, identifying cathode degradation as the dominant failure pathway. Dual PEDOT‐based interfacial protection suppresses these reactions, stabilizes both electrode interfaces, and enables durable wide‐temperature solid ...

Characterizing Biopolymer Electrolytes in Zinc–Air Batteries: Challenges, Best Practices, and a Robust Workflow Guiding Future Research Paths

open access: yesAdvanced Energy Materials, EarlyView.
Bio‐based gel polymer electrolytes promise sustainable, mechanically adaptable zinc–air batteries, yet their progress is constrained by inconsistent characterization. This review critically links formulation, structure, interfaces, and cell performance, identifies methodological gaps under alkaline operating conditions, and proposes application ...

Genetic deletion of genes in the cerebellar rhombic lip lineage can stimulate compensation through adaptive reprogramming of ventricular zone-derived progenitors

open access: yesNeural Development, 2019
Background The cerebellum is a foliated posterior brain structure involved in coordination of motor movements and cognition. The cerebellum undergoes rapid growth postnataly due to Sonic Hedgehog (SHH) signaling-dependent proliferation of ATOH1+ granule ...

Temporary faults impact on the overall availability and reliability of practical large-scale grid-connected photovoltaic systems

open access: yesEnergy Reports, 2023
Temporary faults in photovoltaic (PV) systems can lead to system failure and compromise electronic subassemblies’ availability and reliability (A&R). Accurately assessing A&R in the presence of temporary faults is crucial for designing, operating, and ...

Scale‐space image analysis for mapping spotted knapweed in grassland ecosystems

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise This study investigates the value of scale‐space representations of spatial features for the identification and mapping of invasive plants using high‐resolution multispectral imagery. Scale‐space representations combine the two‐dimensional spatial domain with a third dimension representing spatial scale, such that features can be ...
