At the distance of NGC 5128 (3.6±0.2 Mpc) it is possible to resolve globular clusters with high resolution imaging from the ground, thus allowing the globular cluster candidate selection primarily through their morphological properties. I report the discovery of 71 globular clusters in NGC 5128 on VLT UT1+FORS1 images, including the faintest members (MV ∼ −5) known to date in this galaxy as wel...

An apparatus to measure the coefficient of kinetic friction (mu k) between the shoe sole and the underfoot surface was constructed, and a method including criteria to evaluate the risk of slipping during walking was developed. The apparatus is a prototype stationary step simulator capable of simulating the movements of a human foot and the forces applied to the underfoot surface during an actua...

The Mexican axolotl V(H) segments associated with the Igh C mu and C nu isotypes were isolated from anchored PCR libraries prepared from spleen cell cDNA. The eight new V(H) segments found bring the number of V(H) families in the axolotl to 11. Each V(H) had the canonical structural features of vertebrate V(H) segments, including residues important for the correct folding of the Ig domain. The ...

Let G be a graph of order n, with vertex set $$V=\{v_{1},\dots ,v_{n}\}$$ and adjacency matrix A. For non-empty S vertices let $$\mathrm{e}=(x_{1}, \dots , x_{n})^\mathtt{T}$$ the characteristic vector S, that is, $$x_{\ell }=1$$ if $$v_{\ell }\in S$$ }=0$$ otherwise. Then $$n\times n$$ $$\begin{aligned} W^{S}:=\big [{\mathrm{e}}, A{\mathrm{e}}, A^{2}{\mathrm{e}},\dots ,A^{n-1}{\mathrm{e}}\big ...

The main aim of this paper is to analyse minimally-coupled scalar-fields -- quintessence and phantom as the candidates explain accelerated expansion universe compare its observables current cosmological observations; a byproduct we present python module. This work includes parameter $\epsilon$ which allows incorporate both fields within same analysis. Examples potentials, so far included, are $...

We study the dynamics of a charged tracer particle (TP) on a two-dimensional lattice, all sites of which except one (a vacancy) are filled with identical neutral, hard-core particles. The particles move randomly by exchanging their positions with the vacancy, subject to the hard-core exclusion. In the case when the charged TP experiences a bias due to external electric field E (which favors its...

Schottky contacts have been used to fabricate normally- OFF lateral reverse-blocking MESFETs on p-type (boron-doped) O-terminated monocrystalline diamond. The devices utilized an ohmic source contact but both gate and drain were in nature. Boron-doped p-channel diamond reported date display the less attractive ON characteristics. Here, transistor delivered a current level of ~1.5 <inline-formul...

reason in mu`tazila`s of basreh is explained by interpretations like knowledge, prohibition, thought, opinion, way to achieve knowledge, and apprehension of religious duties. they were the first group of sunnis that benefited from speculative reason in cognition of religion; and argued for good and evil of deeds through practical reason, and rejected vile action of allah, they also argued for d...

During embryonic development, the avian bursa of Fabricius selects B cell precursors that have undergone productive V(D)J recombination for expansion in oligoclonal follicles. During this expansion, Ig diversity is generated by gene conversion. We have used retroviral gene transfer in vivo to introduce surface Ig molecules that lack V(D)J-encoded determinants into B cell precursors. This trunca...

We present a method to generate probability distributions that correspond to metrics obeying partial differential equations generated by extremizing a functional J [g(mu nu) (theta(i)) ] , where g(mu nu) (theta(i)) is the Fisher metric. We postulate that this functional of the dynamical variable g(mu nu) (theta(i)) is stationary with respect to small variations of these variables. Our approach ...
