The integrase of the phage PhiC31 recombines an attP site in the phage genome with a chromosomal attB site of its Streptomyces host. We have utilized the integrase-mediated reaction to achieve episomal and genomic deletion of a reporter gene in mammalian cells, and provide the first comparison of its efficiency with other recombinases in a new assay system. This assay demonstrated that the effi...

We study the one-dimensional random dimer model, with Hamiltonian Hω = ∆ + Vω, where for all x ∈ Z, Vω(2x) = Vω(2x + 1) and where the Vω(2x) are i.i.d. Bernoulli random variables taking the values ±V, V > 0. We show that, for all values of V and with probability one in ω, the spectrum of H is pure point. If V ≤ 1 and V 6= 1/ √ 2, the Lyapounov exponent vanishes only at the two critical energies...
For autonomous mobile robot navigation, localization is an essential capability. Given a equipped with 3D LiDAR sensor, environment map composed of point cloud built beforehand. The thus allowed to localize the position in using sensor scan data. However, sometimes changes due obstacles. Under changing environment, capability might be decreased. this challenge, we propose observation model fram...
We prove that at large disorder, with large probability and for a set of Diophantine frequencies of large measure, Anderson localization in Z is stable under localized time-quasi-periodic perturbations by proving that the associated quasi-energy operator has pure point spectrum. The main tools are the Fröhlich-Spencer mechanism for the random component and the Bourgain-Goldstein-Schlag mechanis...
let $f$ be a locally univalent function on the unit disk $u$. we consider the normalized extensions of $f$ to the euclidean unit ball $b^nsubseteqmathbb{c}^n$ given by$$phi_{n,gamma}(f)(z)=left(f(z_1),(f'(z_1))^gammahat{z}right),$$ where $gammain[0,1/2]$, $z=(z_1,hat{z})in b^n$ and$$psi_{n,beta}(f)(z)=left(f(z_1),(frac{f(z_1)}{z_1})^betahat{z}right),$$in which $betain[0,1]$, $f(z_1)neq 0$ and $...
in this paper a survey to determine the spring and damper settings of itm285 tractor’s cabin which ensured optimal ride comfort of tractor operator was conducted. analysis has been done in terms of root mean square acceleration response (rmsar) in one-third-octave band and international standard organization (iso). optimization was performed using particle swarm optimization (pso) method on a 2...
a quantum theory of a two and three-level laser with injected atomic coherence is developed by using a density operator method, to the best of our knowledge, for the first time. the initial atomic coherence plays an essential role. at steady state, the equation of motion for the density operator yields to exhibit laser without inversion and a phase locking but no threshold for the laser field. ...
