On the Uniform One-dimensional Fragment
The uniform one-dimensional fragment of first-order logic, U1, is a recently introduced formalism that extends two-variable logic in a natural way to contexts with relations of all arities. We survey properties of U1 and investigate its relationship to description logics designed to accommodate higher arity relations, with particular attention given to DLRreg . We also define a description logi...
متن کاملOne-dimensional Fragment of First-order Logic
We introduce a novel decidable fragment of first-order logic. The fragment is one-dimensional in the sense that quantification is limited to applications of blocks of existential (universal) quantifiers such that at most one variable remains free in the quantified formula. The fragment is closed under Boolean operations, but additional restrictions (called uniformity conditions) apply to combin...
متن کاملThe Existential Fragment of the One-Step Parallel Rewriting Theory
It is known that the first-order theory with a single predicate → that denotes one-step rewriting reduction on terms is undecidable already for formulae with ∃∀ prefix. Several decidability results exist for the fragment of the theory in which the formulae start with the ∃ prefix only. This paper considers a similar fragment for a predicate → which denotes the parallel one-step rewriting reduct...
متن کاملOne-step DNA fragment assembly and circularization for gene cloning.
This article describes a one-step procedure based on Taq polymerase for the precise assembly of DNA fragments into circular constructs as long as 6 kb. The only prior step needed was the amplification of the gene to be cloned and the linear vector backbone, and the whole process up to assembly and circularization lasted only 2 days, compared with the conventional method's 2 weeks. Furthermore, ...
متن کاملEngineered IgG1‐Fc – one fragment to bind them all
The crystallizable fragment (Fc) of the immunoglobulin class G (IgG) is a very attractive scaffold for the design of novel therapeutics due to its quality of uniting all essential antibody functions. This article reviews the functionalization of this homodimeric glycoprotein by diversification of structural loops of CH3 domains for the design of Fcabs, i.e. antigen-binding Fc proteins. It repor...
