BACKGROUND We wanted to quantify the impact that polyparasite infections, including multiple concurrent low-intensity infections, have on anemia. METHODS Three stool samples were collected and read in duplicate by the Kato-Katz method in a cross-sectional sample of 507 children from Leyte, The Philippines. The number of eggs per gram of stool was used to define 3 infection intensity categorie...

The cryogenic storage ring CSR is a 35 m circumference electrostatic ring, designed for molecularand atomic physics experiments at MPI-K Heidelberg. It will operate at pressures down to 10 mbar and temperatures <10 K. The beam intensities will be in the range of 1 nA to 1 μA, particle energies with between 20 300 keV. An intensity measurement for coasting beams below 1μA requires magnetic field...

We demonstrate the generation of axially modulated plasma waveguides using spatially patterned high-energy laser pulses. A spatial light modulator (SLM) imposes transverse phase front modulations on a low-energy (10 mJ) laser pulse which is interferometrically combined with a high-energy (130-450 mJ) pulse, sculpting its intensity profile. This enables dynamic and programmable shaping of the la...

Spatial intensity distribution is one of the fundamental parameters that indicate how a laser beam will behave in an application. For example, in a materials processing situation, it is easily understandable why two beams of identical power and diameter leave different burn marks on a substrate if one beam features a Gaussian or near-Gaussian profile (maximum intensity in the beam center), whil...

We introduce a new class of Schell-model temporal sources that admit a closed-form analytical decomposition in terms of coherent pseudo-modes. We explore the source mode and the corresponding eigenvalue structure and demonstrate that the lowest-order mode profile reflects the distribution of the source intensity as a function of time. We also examine the global degree of coherence of the class ...
