Mapping rust, anthracnose and angular leaf spot resistance genes in common bean using RAPD markers Molecular markers were used to study the organization of rust, anthracnose and angular leaf spot resistance genes in common bean (Phaseolus vulgaris) Ouro Negro cultivar. A segregant population of 154 recombinant inbred lines (RIL ́s) from the crossing between Ouro Negro and Rudá cultivars was inoc...

We recall the origin of angular ordering of soft parton emission in the region of small x and show that this coherent structure can be detected in associated distributions. For structure functions at small x and at fixed transverse momentum the angular ordering is masked because of the complete inclusive cancellations of collinear singularities for x → 0. Therefore, in this case the dependence ...

We use non-radiative N-body/SPH simulations of structure formation in a ΛCDM cosmology to compare the angular momentum distributions of dark matter and gas in a large sample of halos. We show that the two components have identical spin parameter distributions and that their angular momentum distributions within individual halos are very similar, all in excellent agreement with standard assumpti...

On Dec 27, 2004, the magnetar SGR 1806-20 underwent an enormous outburst resulting in the formation of an expanding, moving, and fading radio source. We report observations of this radio source with the Multi-Element Radio-Linked Interferometer Network (MERLIN) and the Very Long Baseline Array (VLBA). The observations confirm the elongation and expansion already reported based on observations a...

Large scale structure deflects cosmic microwave background (CMB) photons. Since large angular scales in the large scale structure contribute significantly to the gravitational lensing effect, a realistic simulation of CMB lensing requires a sufficiently large sky area. We describe simulations that include these effects, and present both effective and multiple plane ray-tracing versions of the a...

Photons can carry angular momentum, not only due to their spin, but also due to their spatial structure. This extra twist has been used, for example, to drive circular motion of microscopic particles in optical tweezers as well as to create vortices in quantum gases. Here we excite an atomic transition with a vortex laser beam and demonstrate the transfer of optical orbital angular momentum to ...

Angular distributions of the elastic scattering in the range of 30-160 ~ OCM have been measured for the systems 15N+ 19F, 19F+ 160 and 19F+ 1sO at three energies, the highest being approximately 4 MeV above the Coulomb barrier. The large differences observed in the structure of the angular distributions at large angles are discussed considering elastic transfer, and the angular momentum balance...

In this paper, the effect of Equal Channel Angular Pressing (ECAP) process on the structure and mechanical properties of AM30 magnesium alloy was studied. The results showed a considerable effect of ECAP process on creating an ultrafine grain size structure. Scanning Electron Microscope indicated that the grain size dropped from 20.4 µm in the extruded form to 7.2 µm in the first pass and 3.9 µ...

We design inexact proximal augmented Lagrangian based decomposition methods for convex composite programming problems with dual block-angular structures. Our are particularly well suited quadratic arising from stochastic models. The algorithmic framework is on the application of abstract ADMM developed in [Chen, Sun, Toh, Math. Prog. 161:237–270] to target problem, as recently symmetric Gauss-S...
