    Abstract Sentential Calculus with Identity (SCI) is an extension of classical propositional logic, featuring a new connective of identity between formulas. In SCI two formulas are said to be identical if they share the same denotation. In the semantics of the logic, truth values are distinguished from denotations, hence the identity connective is strictly stronger than classical equivalence. In this paper we present a sound, complete, and terminating algorithm deciding the satisfiability of SCI-formulas, based on labelled tableaux. To the best of our knowledge, it is the first implemented decision procedure for SCI which runs in NP, i.e., is complexity-optimal. The obtained complexity bound is a result of dividing derivation rules in the algorithm into two sets: decomposition and equality rules, whose interplay yields derivation trees with branches of polynomial length with respect to the size of the investigated formula. We describe an implementation of the procedure and compare its performance with implementations of other calculi for SCI (for which, however, the termination results were not established). We show possible refinements of our algorithm and discuss the possibility of extending it to other non-Fregean logics.

    Abstract Retrotransposons represent a significant part of the genome in eukaryote organisms. With DNA transposons, they belong to mobile genetic elements. There are two classes of transposons, DNA transposons and retrotransposons. Retrotransposons have three genes in their structure (gag, pol, env), responsible for the activation and encoding of structural proteins and envelope proteins. There is a group of retroelements without LTR (non-LTR). This group consists LINE (Long Interspersed Nuclear Elements) and SINE (Short Interspersed Nuclear Elements) sequences. LINE sequences represent 20% of human genetic material. Sequences of retrotransposons can move within the genome of a particular organism, occasionally subjected to replication as a result of enzyme activity, i.e. reverse transcriptase. The process of retro transposition is imperfect. These processes often cause mutation (most often: insertion, deletion), genetic instability, they contribute to the development of diseases on the genetic basis, including cancer. Retrotransposons are also used to analyze genetic variation as genetic markers.
