Bi‐embeddability spectra and bases of spectra [PDF]
Mathematical Logic Quarterly, 2019 AbstractWe study degree spectra of structures with respect to the bi‐embeddability relation. The bi‐embeddability spectrum of a structure is the family of Turing degrees of its bi‐embeddable copies. To facilitate our study we introduce the notions of bi‐embeddable triviality and basis of a spectrum.

Algebras and Representation Theory, 2022 AbstractThe aim of this paper is to investigate the behaviour of prime and semiprime subgroups of groups, and their relation with the existence of abelian normal subgroups. In particular, we study the set Spec(G) of all prime subgroups of a group G endowed with the Zariski topology and, among other examples, we construct an infinite group whose proper ...

Spectra, spectra, spectra – Tensor triangular spectra versus Zariski spectra of endomorphism rings [PDF]
Algebraic & Geometric Topology, 2010 The author [\textit{P. Balmer}, J. Reine Angew. Math. 588, 149--168 (2005; Zbl 1080.18007)] has introduced the notion of a triangular spectrum \(\text{Spc}(\mathcal{K})\) for a tensor triangulated category \(\mathcal{K}\). From the previous work of the author and others it is clear that \(\text{Spc}(\mathcal{K})\) is a natural home for triangular ...

GIS-based decision support tool for evidence-based policy making for biodiversity protection [PDF]
MATEC Web of ConferencesGeographic Information Systems (GIS) based decision support systems can play a crucial role in protecting biodiversity in spatial planning. These systems use spatial data and analytical tools to help decision-makers identify areas of high biodiversity ...

Real Spectra in Non-Hermitian Hamiltonians Having PT Symmetry [PDF]
, 1997 The condition of self-adjointness ensures that the eigenvalues of a Hamiltonian are real and bounded below. Replacing this condition by the weaker condition of $\mathrm{PT}$ symmetry, one obtains new infinite classes of complex Hamiltonians whose spectra

The Journal of Symbolic Logic, 2015 AbstractThe mad spectrum is the set of all cardinalities of infinite maximal almost disjoint families on ω. We treat the problem to characterize those sets ${\rm {\cal A}} $ which, in some forcing extension of the universe, can be the mad spectrum.

Discrete G-spectra and embeddings of module spectra [PDF]
Journal of Homotopy and Related Structures, 2017 In this paper we study the category of discrete G-spectra for a profinite group G. We consider an embedding of module objects in spectra into a category of module objects in discrete G-spectra, and study the relationship between the embedding and the homotopy fixed points functor.

Short‐duration post CT‐guided thoracic biopsy monitoring‐ clinical experience with 440 patients
Journal of Medical Radiation Sciences, 2019 Purpose With several studies recording a higher percentage of complications in the first hour of post‐biopsy, this study sought to evaluate the safety in the reduction in post‐biopsy patient monitoring time after computed tomography (CT)‐guided thoracic ...
