Two-Stage Atomic Decomposition of Multichannel EEG and the Previously Undetectable Sleep Spindles [PDF]
SensorsWe propose a two-step procedure for atomic decomposition of multichannel EEGs, based upon multivariate matching pursuit and dipolar inverse solution, from which atoms representing relevant EEG structures are selected according to prior knowledge.

Atomic decompositions of Lorentz martingale spaces and applications
Journal of Function Spaces and Applications, 2009 In the paper we present three atomic decomposition theorems of Lorentz martingale spaces. With the help of atomic decomposition we obtain a sufficient condition for sublinear operator defined on Lorentz martingale spaces to be bounded.

Active nitrogen mediated selective ruthenium migration on ceria for high pressure ammonia decomposition [PDF]
Nature CommunicationsPrecise stabilization of atomic structures under reaction environments remains a central challenge in heterogeneous catalysis. Here, we demonstrate that ammonia (NH3) serves as a chemically active nitrogen source to derive the selective migration of ...

SparsePool: A Graph Pooling Framework via Sparse Representation for Graph Classification [PDF]
SensorsGraph neural networks (GNNs) have achieved great success in graph classification, with graph pooling methods being widely adopted for related tasks. Existing approaches typically rely on node ranking or clustering to coarsen graphs, but often fail to ...

Atomic Formulation of the Boolean Curve Fitting Problem [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2022 Boolean curve fitting is the process of finding a Boolean function that takes given values at certain points in its Boolean domain. The problem boils down to solving a set of ‘big’ Boolean equations that may or may not be consistent.

On generalized Hardy spaces associated with singular partial differential operators
Cubo, 2023 We define and study the Hardy spaces associated with singular partial differential operators. Also, a characterization by mean of atomic decomposition is investigated.

Approximative K-atomic decompositions and frames in Banach spaces [PDF]
Arab Journal of Mathematical Sciences, 2020 L. Gǎvruţa (2012) introduced a special kind of frames, named K-frames, where K is an operator, in Hilbert spaces, which is significant in frame theory and has many applications.

Variable Anisotropic Hardy Spaces with Variable Exponents
Analysis and Geometry in Metric Spaces, 2021 Let p(·) : ℝn → (0, ∞] be a variable exponent function satisfying the globally log-Hölder continuous and let Θ be a continuous multi-level ellipsoid cover of ℝn introduced by Dekel et al. [12].

Atomic-scale imaging of CH3NH3PbI3 structure and its decomposition pathway
Nature Communications, 2021 The knowledge of atomic structure and structural instability of hybrid perovskites is crucial to understand their photoelectric properties and failure mechanism. Here, the authors utilise low-dose TEM imaging technique to investigate the atomic structure
