Weak Implication on Generalized Lukasiewicz Algebras of Order

J. Vaz De Carvalho and T. Almada in A generalization of the Lukasiewicz algebras, Studia Logica 69 (2001), 329-338 introduced the variety Ln , m ≥ 1, n ≥ 2, of m–generalized Lukasiewicz algebras of order n as a generalization of Lukasiewicz algebras of order n and a particular case of Ockham algebras. In this note, bearing in mind the important role that weak implication played in the study of ...

On the Implication Problem for Functional Dependencies in the Higher-Order Entity-Relationship Model

Origin and implication of ellipticity in high-order harmonic generation from aligned molecules

We address theoretically and numerically the possibility of observing ellipticity in high-order harmonic generation (HHG) from aligned molecules driven by linearly polarized fields—a subject of controversy in the recent literature with significant implications. To that end we develop a numerical method for solution of the electronic dynamics and extend a recently developed theory of HHG from al...

Higher-order architecture of rhodopsin in intact photoreceptors and its implication for phototransduction kinetics.

The visual pigment rhodopsin belongs to the family of G protein-coupled receptors that can form higher oligomers. It is controversial whether rhodopsin forms oligomers and whether oligomers are functionally relevant. Here, we study rhodopsin organization in cryosections of dark-adapted mouse rod photoreceptors by cryoelectron tomography. We identify four hierarchical levels of organization. Rho...
