Performance of Single-Epoch EWL/WL/NL Ambiguity-Fixed Precise Point Positioning with Regional Atmosphere Modelling

Remote Sensing, 2021
Precise point positioning (PPP) with ambiguity resolution (AR) can improve positioning accuracy and reliability. The narrow-lane (NL) AR solution can reach centimeter-level accuracy but there is a certain initialization time. In contrast, extra-wide-lane

Comprehensive Analysis of the Degradation Phenomena of Proton Exchange Membrane Water Electrolyzers with Iridium on Antimony Tin Oxide Anodes

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study examines the structural and chemical evolution of low‐loaded Ir/ATO anodes during PEM water electrolysis under realistic conditions. Iridium dissolution is largely suppressed. In the early stages, both ionomer and support degradation are detected. Morphological reorganization occurs at the interface between the anode catalyst layer (ACL) and

Tumor‐educated platelets in cancer diagnostics and prognostics: A critical appraisal and roadmap for clinical translation

International Journal of Cancer, EarlyView.
Abstract Tumor‐educated platelets (TEPs) are emerging as a compelling frontier in liquid biopsy, functioning as dynamic, systemic sensors that sequester and process tumor‐derived biomolecules. This interaction imprints an integrated molecular signature of malignancy—spanning the transcriptome, proteome, lipidome, and crucially, the captured genome ...

Policy Capacity for Novel Technology Adoption: Developmental Insights From Singapore's AI Adoption in Long‐Term Care

Public Administration and Development, EarlyView.
ABSTRACT Worldwide, artificial intelligence‐driven technologies, including robotics and autonomous systems (RAS), are adopted to address manpower shortages in long‐term care. However, their effective use requires a reasonable degree of policy capacity across individual‐, organisational‐ and system‐levels.

Chiral‐Induced Spin‐Polarized Molecular Switching in a Magneto‐Controlled 2D System using Electrical Readouts

Small, EarlyView.
Through molecular engineering, an unconventional chiral 2D platform based on covalently functionalized 2D germanane achieved magneto‐controlled spin‐dependent electron transport, which can be further tuned through the enantiomeric configuration of the chiral ligand.

Broke Autocrats, Broken Elections: Trade Shocks and Electoral Fraud in Autocracies

Economics &Politics, EarlyView.
ABSTRACT We argue that when terms‐of‐trade (ToT) shocks reduce resource rents, autocrats lose the fiscal capacity to sustain loyalty through patronage and increasingly rely on electoral manipulation as a survival strategy. We present a simple model in which rents finance patronage in normal times, while adverse shocks reduce the effectiveness of ...
