Strict Identity with No Overlap

Homology-dependent interactions determine the order of strand exchange by IntDOT recombinase

The Bacteroides conjugative transposon CTnDOT encodes an integrase, IntDOT, which is a member of the tyrosine recombinase family. Other members of this group share a strict requirement for sequence identity within the region of strand exchange, called the overlap region. Tyrosine recombinases catalyze recombination by making an initial cleavage, strand exchange and ligation, followed by strand ...

Algebraic semantics for a modal logic close to S1

The modal systems S1–S3 were introduced by C. I. Lewis as logics for strict implication. While there are Kripke semantics for S2 and S3, there is no known natural semantics for S1. We extend S1 by a Substitution Principle SP which generalizes a reference rule of S1. In system S1+SP, the relation of strict equivalence φ ≡ ψ satisfies the identity axioms of R. Suszko’s non-Fregean logic adapted t...

Evaluation Performance of OFDM Mutlicarrier Modulation over Rayleigh and RicianStandard Channels Using WPT-OFDM Modulations

Last years, Wavelet Packet Modulation (WPM) or Wavelet Packet Transform based Orthogonal Frequency Division Multiplexing (WPT-OFDM) have been introduced to wired and wireless communication fields as efficient Multicarrier Modulation (MCM) techniques. The wavelets have interesting features such as flexibility, compatibility and localization in both time and frequency domains with no need to use ...

Determination of The Relationship Between Severity of Obstructive Sleep Apnea And Chronic Obstructive Pulmonary Disease

Introduction: Chronic obstructive pulmonary disease (COPD) patients are at increased risk of sleep-disorders. The concomitant occurrence of COPD and obstructive sleep apnea hypopnea syndrome (OSAHS) is named overlap syndrome. This study aimed to evaluate the severity of OSAHS in overlap syndrome patients.Materials & Methods: This cross-sectional study was conducted on adult patients with forced...
