A Novel Sparse Bayesian Space-Time Adaptive Processing Algorithm to Mitigate Off-Grid Effects

open access: yes, 2022
Space-time adaptive processing (STAP) algorithms based on sparse recovery (SR) have been researched because of their low requirement of training snapshots.

From living to fossil: ancestral state reconstruction of leaf architecture in extant Lauraceae and its relevance for the fossil record

open access: yesPalaeontology, Volume 69, Issue 3, 2026.
Abstract Lauraceae are a tropical–subtropical angiosperm family that exhibit significant diversity and a rich fossil record, primarily of leaves found worldwide from the Cretaceous to the present. However, the taxonomic placement of many fossil leaves remains uncertain because of morphological convergence and limited variation in leaf characters among ...

An Overview on Sparse Recovery-based STAP

open access: yesLeida xuebao, 2014
This paper gives a brief review on the Sparse-Recovery (SR)-based Space-Time Adaptive Processing (STAP) technique. First, the motivation for introducing sparse recovery into STAP is presented.

Using multilayer socioecological networks to assess ecosystem service flow in a subsistence farming community in Papua New Guinea

open access: yesPeople and Nature, Volume 8, Issue 4, Page 854-870, April 2026.
Abstract Ecosystem services are rapidly degrading under anthropogenic pressure. Therefore, it is increasingly important to understand how ecosystem services flow, particularly at local scales, where people directly rely on nature for their livelihoods and well‐being. Many ecosystem services are underpinned by ecological (e.g.

Robust knowledge-aided sparse recovery STAP method for non-homogeneity clutter suppression

open access: yesThe Journal of Engineering, 2019
Conventional space–time adaptive processing (STAP) methods would suffer severely performance loss in the complex clutter environment of an airborne-phased array radar, especially when the estimated clutter covariance matrix (CCM) is corrupted by the ...

Land Use and Economic Trade‐Offs of Large‐Scale Solar in Agricultural Regions: Marginal National Impacts, Significant Regional Variations

open access: yesAustralian Journal of Agricultural and Resource Economics, Volume 70, Issue 2, Page 395-409, April 2026.
ABSTRACT Large‐scale solar generation is critical for energy transitions. In Australia, increased solar production to meet emission targets means its land footprint increasingly competes with agricultural land. Understanding the scale and location of agricultural land use change and potential profitability losses from large‐scale solar farms is ...

Stap2Go Test: Validity and Sensitivity/Specificity for Attention and Executive Function Assessment

open access: yesApplied Cognitive Psychology, Volume 40, Issue 2, March/April 2026.
ABSTRACT Attention and executive function difficulties are common in many neurodevelopmental conditions and significantly impact psychological well‐being. However, access to cognitive assessment remains limited due to high costs and resource constraints.

A Grid-Less Total Variation Minimization-Based Space-Time Adaptive Processing for Airborne Radar

open access: yesIEEE Access, 2020
Sparse recovery (SR) based space-time adaptive processing (STAP) has attracted much attention due to its small requirement of snapshots in the estimation of the clutter plus noise covariance matrix (CNCM).

Best Practice in Climate Change Adaptation

open access: yesWIREs Climate Change, Volume 17, Issue 2, March/April 2026.
The seven elements of best practice in climate change adaptation. ABSTRACT Climate change adaptation has become a core business for international organizations, firms, and all levels of government in almost every country. Practitioners seek to implement adaptation in the face of myriad barriers and uncertainties and so seek guidance as to what ...
