Frames and semi-frames [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2011
Loosely speaking, a semi-frame is a generalized frame for which one of the frame bounds is absent. More precisely, given a total sequence in a Hilbert space, we speak of an upper (resp. lower) semi-frame if only the upper (resp. lower) frame bound is valid.

Effect of a non-hydrostatic core-mantle boundary on the nutations and Length-of-day of Mars [PDF]

open access: yesAnnales Geophysicae
Dynamic loads in planetary mantles have the potential to deform the core-mantle boundary (CMB). On Earth, subducting slabs primarily induce a degree 2–order 2 deformation of the CMB in the spherical harmonic (SH) reference system.

Conceptual structure and semantic structure of the discourse of « In those arms » a novel of Camille Laurens [PDF]

open access: yesBeni-Suef University International Journal of Humanities and Social Sciences, 2021
This research proposes a cognitive semantic study of the mental framework of the self in search of its identity in the universe of the other. It is the self of the heroine of Camille Laurens' novel Dans ces bras-là, which espouses a postmodern vision in ...

Matrices related to some Fock space operators [PDF]

open access: yesOpuscula Mathematica, 2011
Matrices of operators with respect to frames are sometimes more natural and easier to compute than the ones related to bases. The present work investigates such operators on the Segal-Bargmann space, known also as the Fock space.

Frame Construction and Frame Promotion (Strategic Framing Choices) [PDF]

open access: yesAmerican Behavioral Scientist, 2012
In this article, the authors discuss the three most important strategic framing choices by political actors (“substantive emphasis choice,” “oppositional emphasis choice,” and “contest emphasis choice”) of direct-democratic campaigns. The authors investigate these strategic framing choices in the media input and look at how the political actors change ...

Behavior of structural concrete frames with hybrid reinforcement under cyclic loading

open access: yesFracture and Structural Integrity, 2021
A substantial amount of work was carried out on the use of fiber-reinforced polymer (FRP) in reinforced concrete structural elements, which demonstrated considerable inelasticity or deformity through monotonic and cyclic loads. Even so, the action of FRP

Development and Experimentation of a New Mathematical Model for Teaching–Learning the Radioactive Decay Law

open access: yesEducation Sciences, 2019
Our plan is to bring professors and their Moroccan pupils to focus on the teaching−learning of physics, without adopting forced mathematical modeling in previously unknown frames and registers, as is actually the practice.

On Construction of Bounded Sets Not Admitting a General Type of Riesz Spectrum

open access: yesAxioms
We construct a bound set that does not admit a Riesz spectrum containing a nonempty periodic set for which the period is a rational multiple of a fixed constant.
