We study the evolution of mutation rates for an asexual population living on a static fitness landscape, consisting of multiple peaks forming an evolutionary staircase. The optimal mutation rate is found by maximizing the diffusion towards higher fitness. Surprisingly the optimal genomic copying fidelity is given by Qopt = e − 1 ln ν (where ν is the genome length), independent of all other para...

objective(s): lupus nephritis (ln) is the main cause of mortality and disability in systemic lupus erythematosus (sle) patients. therefore, utilizing a reliable and non-invasive method for serial measurements of renal function seems to be necessary. the aim of this study was to evaluate the role of urinary lipocalin-2 as a biomarker of renal involvement in sle patients.   materials and methods:...

Objective(s)Lupus nephritis (LN) is frequently associated with a poor long-term prognosis. Renal biopsy is the diagnostic method of choice in this condition. Urine biomarkers have been mentioned in the diagnosis of LN. The study,s purpose was to evaluate the performance of urinary monocyte chemoattractant protein 1(UMCP-1) as a biomarker of renal involvement in systemic lupus erythematosus.Mate...

On the Algebraic Bethe Ansatz for XXX spin chain: creation operators " beyond the equator ". Abstract Considering the XXX spin-1/2 chain in the framework of the Algebraic Bethe Ansatz (ABA) we make the following short comment: the product of the creation operators corresponding to the recently found solution of the Bethe equations " on the wrong side of the equator " [1] is just zero (not only ...
