A Broadband Study of Galactic Dust Emission [PDF]
, 2006 We have combined infrared data with HI, H2 and HII surveys in order to spatially decompose the observed dust emission into components associated with different phases of the gas. An inversion technique is applied.

Reaction-dominated combustion control of ammonium perchlorate-based composites by layered V2C MXene
Energetic Materials Frontiers, 2022 Reactive combustion catalysts (RCCs) are emerging materials for the combustion control of ammonium perchlorate (AP)-based propellants owing to their unique ability to control burning rates, high atomic utilization, and high-energy output.

Frequency-Selective Vandermonde Decomposition of Toeplitz Matrices with Applications
, 2017 The classical result of Vandermonde decomposition of positive semidefinite Toeplitz matrices, which dates back to the early twentieth century, forms the basis of modern subspace and recent atomic norm methods for frequency estimation.

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.

Spherical Harmonic Atomic Norm and its Application to DOA Estimation
IEEE Access, 2019 Signal processing in the spherical harmonic (SH) domain has the advantages of analyzing a signal on the sphere with equal resolution in the whole space and of decomposite the frequency- and location-dependent components of the signal. Therefore, it finds

On new sharp theorems for multifunctional BMOA type spaces in bounded pseudoconvex domains
Vestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2020 We provide new equivalent expressions in the unit ball and pseudoconvex domains for multifunctional analytic BMOA type space. We extend in various directions a known theorem of atomic decomposition of BMOA type spaces in the unit ball.

Perturbations of Banach Frames and Atomic Decompositions [PDF]
Mathematische Nachrichten, 1997 AbstractBanach frames and atomic decompositions are sequences that have basis‐like properties but which need not be bases. In particular, they allow elements of a Banach space to be written as linear combinations of the frame or atomic decomposition elements in a stable manner.

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity
Molecular Oncology, EarlyView.Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve
