A Space-Time Adaptive Processing Method Based on Sparse Reconstruction of Reverberation Interference
Xibei Gongye Daxue Xuebao, 2020 Aiming at the problem of how to obtain reverberation samples and estimate their covariance matrix in the space-time adaptive processing(STAP) of sonar system, a new space-time adaptive processing method is proposed based on sparse reconstruction of ...

The Grammar of Perception: A Case Study of Guambiano (Namtrik) and Duna
Topics in Cognitive Science, EarlyView.Abstract Although the senses provide a common basis for our experience of the world, cross‐linguistic research has revealed substantial diversity across languages in how perceptual experiences are encoded in words. Such variability is also present at the level of grammatical structure, though the project of charting the parameters and limits of cross ...

An improved adaptive sidelobe blanker [PDF]
, 2008 We propose a two-stage detector consisting of a subspace detector followed by the whitened adaptive beamformer orthogonal rejection test. The performance analysis shows that it possesses the constant false alarm rate property with respect to the unknown

Ecology and Evolution, Volume 16, Issue 8, August 2026.Phylogeographic pseudo‐concordance among species—coincident spatial structuring coupled with differing levels of intraspecific differentiation—has rarely been documented in heterogeneous regions. We report a clear case in two mountain butterfly species and show how the high density of spatial sampling and the integration of phenotypic and genomic ...

Delivery of Pleckstrin‐Homology Domains Suppresses PI3K/Akt Signaling and Breast Cancer Metastasis
Advanced Science, Volume 13, Issue 30, 28 May 2026.Current therapies curb tumor growth but not metastasis. Obscurin, a giant metastasis suppressor lost in breast cancer, restrains PI3K/Akt signaling but is impractical to restore. We deploy a mini‐obscurin, comprising the obscurin‐PH‐domain, which sequesters PI3K‐p85, potently suppressing invasion and metastasis.

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