Privileged Chiral Photocatalysts

open access: yesAngewandte Chemie, EarlyView.
Privileged chiral catalysts have transformed asymmetric synthesis, conferring generality to processes that are routinely leveraged in the construction of societally important functional small molecules. This mini‐review is intended to survey the conception and evolution of privileged chiral photocatalyst scaffolds that enable simultaneous orchestration

Meinong and Husserl on Existence. Two Solutions of the Paradox of Non-Existence

open access: yesPhilosophia Scientiæ, 2014
This paper analyzes and compares the attempts at solving the paradox of non-existence put forward by Alexius Meinong and Edmund Husserl. It will be argued that Meinong's solution is not convincing since he retreats from the field of predicate logic, in ...

Existence Predicate and Referentiality [PDF]

open access: yesحکمت معاصر, 2015
This essay critically studies one of the important criticisms of the existence predicate, i.e. the referentiality/ non–referentiality proof. Also, it wants to show some of the weaknesses of the following views: (1) existence by no means is a predicate ...

Intuitionistic Layered Graph Logic: Semantics and Proof Theory [PDF]

open access: yesLogical Methods in Computer Science, 2018
Models of complex systems are widely used in the physical and social sciences, and the concept of layering, typically building upon graph-theoretic structure, is a common feature.

Higher-Order Termination: from Kruskal to Computability [PDF]

open access: yes, 2006
Termination is a major question in both logic and computer science. In logic, termination is at the heart of proof theory where it is usually called strong normalization (of cut elimination).

Model Theory and Proof Theory of Coalgebraic Predicate Logic [PDF]

open access: yesLogical Methods in Computer Science, 2018
We propose a generalization of first-order logic originating in a neglected work by C.C. Chang: a natural and generic correspondence language for any types of structures which can be recast as Set-coalgebras.

The Cognitive Ontogenesis of Predicate Logic

open access: yesNotre Dame J. Formal Log., 2014
Since Aristotle and the Stoa, there has been a clash, worsened by modern predicate logic, between logically defined operator meanings and natural intuitions.

Constraints on predicate invention [PDF]

open access: yes, 1991
This chapter describes an inductive learning method that derives logic programs and invents predicates when needed. The basic idea is to form the least common anti-instance (LCA) of selected seed examples.

Influences of Frege’s Predicate Logic on Some Computational Models [PDF]

open access: yesFuture Human Image, 2018
The purpose of this paper is to give some insights into the immense role of Frege’s first order logic (FOL) in the development of computer science. We argue that the FOL is fundamental in computer science, and that some computer science subfields could ...
