Duality for powerset coalgebras [PDF]

open access: yesLogical Methods in Computer Science, 2022
Let CABA be the category of complete and atomic boolean algebras and complete boolean homomorphisms, and let CSL be the category of complete meet-semilattices and complete meet-homomorphisms. We show that the forgetful functor from CABA to CSL has a left

Prospective 3D Fat Navigator (FatNav) motion correction for 7T Terra MRI. [PDF]

open access: yesNMR Biomed
We implemented prospective 3D FatNav motion correction for Siemens 7T Terra MRI scanners. We compared registration algorithms in synthetic data. We tested in healthy volunteers: corrected images were visually crisper, and had improved sharpness measured by increased variance of the image Laplacian and by sharper profiles across the cerebral falx ...

Homological Bondal-Orlov localization conjecture for rational singularities

open access: yesForum of Mathematics, Sigma, 2023
Given a resolution of rational singularities $\pi \colon {\tilde {X}} \to X$ over a field of characteristic zero, we use a Hodge-theoretic argument to prove that the image of the functor ${\mathbf {R}}\pi _*\colon {\mathbf {D}}^{\mathrm {b}}({\

Persian Deadjectival Nominals: An Exoskeletal Approach [PDF]

open access: yesزبان پژوهی, 2020
Nominalized words are complex nominals, which have their own particular derivational structure. These nominals can be derived from different parts of speech. Correspondingly, a deadjectival nominal is a nominal that is derived from an adjective; Although

Universal Properties in Quantum Theory [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2019
We argue that notions in quantum theory should have universal properties in the sense of category theory. We consider the completely positive trace preserving (CPTP) maps, the basic notion of quantum channel.

Comparison theorems for Kan, faintly universal and strongly universal derived functors [PDF]

open access: yesSurveys in Mathematics and its Applications, 2022
We distinguish between faint, weak, strong and strict localizations of categories at morphism families and show that this framework captures the different types of derived functors that are considered in the literature.

Innocent Strategies as Presheaves and Interactive Equivalences for CCS [PDF]

open access: yesScientific Annals of Computer Science, 2012
Seeking a general framework for reasoning about and comparing programming languages, we derive a new view of Milner's CCS. We construct a category E of plays, and a subcategory V of views.

Generalizing determinization from automata to coalgebras [PDF]

open access: yesLogical Methods in Computer Science, 2013
The powerset construction is a standard method for converting a nondeterministic automaton into a deterministic one recognizing the same language. In this paper, we lift the powerset construction from automata to the more general framework of coalgebras ...
