Abstract We study the total branch length Ln of the Bolthausen-Sznitman coalescent as the sample size n tends to infinity. Asymptotic expansions for the moments of Ln are presented. It is shown that Ln/E(Ln) converges to 1 in probability and that Ln, properly normalized, converges weakly to a stable random variable as n tends to infinity. The results are applied to derive a corresponding limiti...

Two 3d-4f hetero-metal pentanuclear complexes with the formula {[CrIII2LnIII3L10(OH)6(H2O)2]Et3NH} [Ln=Tb (1), Dy (2); HL=pivalic acid, Et3N=triethylamine] have been produced. The metal core of each cluster is made up of a trigonal bipyramid with three LnIII ions (plane) and two CrIII ions (above and below) held together by six μ3-OH bridges. Also reported with this series is the diamagnetic Cr...

bovine leukosis virus (blv) is a retrovirus that primarily affects lymphoid tissue of cattle. to determine the seroprevalence of enzootic bovine leukosis virus infection and its effects on some clinical, hematological and flow cytometric indications, this study was conducted on 197 holstein cattle slaughtered in an abattoir in tehran province. elisa gp51 test of the obtained serums of the anima...

New 8-quinolinolate (Q) complexes of yttrium (1) and ytterbium (2) were synthesized by the reactions of Cp3Y and Yb[N(SiMe3)2]3 with 3 equiv. of 8-hydroxyquinoline in a DME solution. Single crystal X-ray analysis revealed the trinuclear molecular structure of the compounds Ln3Q9. The LDI-TOFMS investigation displayed that under the laser impact the compounds split off Q(-) anions to give Ln3Q8(...

Let φN , N ≥ 1, be Daubechies’ scaling function with symbol ( 1+e−iξ 2 )N QN (ξ), and let sp(φN ), 0 < p ≤ ∞, be the corresponding Lp Sobolev exponent. In this paper, we make a sharp estimation of sp(φN ), and we prove that there exists a constant C independent of N such that N − ln |QN (2π/3)| ln 2 − C N ≤ sp(φN ) ≤ N − ln |QN (2π/3)| ln 2 . This answers a question of Cohen and Daubeschies (Re...

The influence of physical aging on the β relaxation in La60Ni15Al25 bulk metallic glass has been investigated by mechanical spectroscopy. The amplitude of the β relaxation (ΔG″) decreases while its relaxation time (τ(β)) increases during aging. We find that, as in organic glasses, the changes of ln (τ(β)) and ln (ΔG(max) ) are linearly correlated with ln (τ(β)) = b - a ln (G(max)″). This behavi...

Human and animal diabetes mellitus were controlled by a dietary treatment supplemented with either a sulfonylurea drug or insulin injection. Insulin injections were inconvenient and the hypoglycemia induced by insulin-overdose could be fatal. Sulfonylurea drugs were administered orally, however, do not typically provide satisfactory control of blood glucose as a starting treatment in 25% 30% pa...

Human endogenous retroviruses (ERVs) have been found to be associated with different diseases, e.g., multiple sclerosis (MS). Most human ERVs integrated in our genome are not competent to replicate and these sequences are presumably silent. However, transcription of human ERVs can be reactivated, e.g., by hypoxia. Interestingly, MS has been linked to hypoxia since decades. As some patterns of d...

We have previously reported that expression of the melanoma-associated antigen (MAA) recognized by MM2-9B6 monoclonal antibody in B16 melanoma was closely associated with C-type ecotropic retroviral particle production. Our present data show that this MAA is encoded by the env gene of an ecotropic retrovirus produced by B16 melanoma cells. Transfection of H-2Kb or H-2Kd genes into two individua...
