Abstract We study the $E_2$ -algebra $\Lambda \mathfrak {M}_{*,1}:= \coprod _{g\geqslant 0}\Lambda {M}_{g,1}$ consisting of free loop spaces moduli Riemann surfaces with one parametrised boundary component, and compute homotopy type group completion $\Omega B\Lambda {M}_{*,1}$ : it is product ^{\infty }\mathbf {MTSO}(2)$ a certain }$ -space depending on family all boundary-irreducible mapping c...

Chi's are genetic elements that stimulate generalized recombination in their locale in phage lambda. All Chi's wherever located on lambda's chromosome, act asymmetrically in crosses blocked in DNA replication: (1) They stimulate exchange primarily to their left on the conventional lambda map, and (2) the stimulated exchange is frequently nonreciprocal, the recombinant carrying the Chi element b...

At a given wavelength lambda we determine all possible solution pairs (?, zeta) of the incidence angle ? and the thickness zeta of a transparent thin film on an absorbing substrate that achieve a given unpolarized light reflectance R(u). The trajectory of the point that represents a solution pair in the zeta, ? plane depends on the optical properties of the film and substrate and on whether R(u...

In this paper we investigate common xed point theorems for contraction mapping in fuzzy metric space introduced by Gregori and Sapena [V. Gregori, A. Sapena, On xed-point the- orems in fuzzy metric spaces, Fuzzy Sets and Systems, 125 (2002), 245-252].

RecBCD is a multifunctional enzyme involved in DNA degradation and homologous recombination. It also produces an endonucleolytic cleavage near properly oriented chi sites (5'-GCTGGTGG-3'). Plasmids are not known to be affected by either RecBCD enzyme or the presence of a chi site. We report here that plasmids that replicate by a rolling circle mechanism accumulate large amounts of high molecula...

BACKGROUND Resistance training (RT) and dietary protein independently influence indexes of whole-body glucose control, though their synergistic effects have not yet been documented. OBJECTIVE This study assessed the influence of dietary protein intake on RT-induced changes in systemic glucose tolerance and the contents of skeletal muscle insulin signaling proteins in healthy older persons. ...

Circulating dehydroepiandrosterone (DHEA) is converted to testosterone or estrogen in the target tissues. Recently, we demonstrated that skeletal muscles are capable of locally synthesizing circulating DHEA to testosterone and estrogen. Furthermore, testosterone is converted to 5alpha-dihydrotestosterone (DHT) by 5alpha-reductase and exerts biophysiological actions through binding to androgen r...

The intimin gene eae, located within the locus of enterocyte effacement pathogenicity island, distinguishes enteropathogenic Escherichia coli (EPEC) and some Shiga toxin-producing E. coli (STEC) strains from all other pathotypes of diarrheagenic E. coli. EPEC is a leading cause of infantile diarrhea in developing countries, and intimin-positive STEC isolates are typically associated with life-t...
