On the spectrum of superspheres [PDF]
Journal of High Energy Physics, 2015 Sigma models on coset superspaces, such as odd dimensional superspheres, play an important role in physics and in particular the AdS/CFT correspondence. In this work we apply recent general results on the spectrum of coset space models and on supergroup WZNW models to study the conformal sigma model with target space S^{3|2}.

Real Spectrum Versus ℓ-Spectrum via Brumfiel Spectrum [PDF]
Algebras and Representation Theory, 2021 It is well known that the real spectrum of any commutative unital ring, and the ${\ell}$-spectrum of any Abelian lattice-ordered group with order-unit, are all completely normal spectral spaces. We prove the following results: (1) Every real spectrum can be embedded, as a spectral subspace, into some ${\ell}$-spectrum. (2) Not every real spectrum is an

Proceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 1998 A new method for analysing nonlinear and non-stationary data has been developed. The key part of the method is the ‘empirical mode decomposition’ method with which any complicated data set can be decomposed into a finite and often small number of ...

Singular Spectrum Analysis: Methodology and Comparison
Journal of Data Science, 2021 In recent years Singular Spectrum Analysis (SSA), used as a powerful technique in time series analysis, has been developed and applied to many practical problems. In this paper, the performance of the SSA tech- nique has been considered by applying it to

Local spectrum and generalized spectrum [PDF]
Proceedings of the American Mathematical Society, 1991 This paper provides the proofs of those results announced in [ 5 , § 5 ] [5,\S 5] that deal with the connection between the regular set and the local resolvant set of closed operators on a Hilbert space. We also give some characterizations and properties of Cowen-Douglas operators.

Practical Evaluation Method of Large Size IRS: Synthesis of Reflection Pattern of Sub-IRS
IEEE Access, 2023 Intelligent reflecting surfaces (IRSs) have been attracting attention as a solution to coverage hole problems in millimeter-wave communication areas and are considered one of the key technologies of next-generation mobile communication systems.

Spectrum matching in licensed spectrum sharing [PDF]
Transactions on Emerging Telecommunications Technologies, 2018 AbstractSpectrum sharing is one of the promising solutions to meet the spectrum demand in fifth‐generation networks that results from the emerging services like machine‐to‐machine and vehicle‐to‐infrastructure communication. The idea is to allow a set of entities to access the spectrum whenever and wherever it is unused by the licensed users.

The Spectrum of the Universe [PDF]
Applied Spectroscopy, 2018 Cosmic background (CB) radiation, encompassing the sum of emission from all sources outside our own Milky Way galaxy across the entire electromagnetic spectrum, is a fundamental phenomenon in observational cosmology. Many experiments have been conceived to measure it (or its constituents) since the extragalactic Universe was first discovered; in ...
