PREMISE OF THE STUDY Eleven nuclear and four plastid microsatellite markers were screened for two gypsum endemic species, Oenothera gayleana and O. hartwegii subsp. filifolia, and tested for cross-amplification in the remaining 11 taxa within Oenothera sect. Calylophus (Onagraceae). METHODS AND RESULTS Microsatellite markers were tested in two to three populations spanning the ranges of both ...

UNLABELLED PREMISE OF THE STUDY The locally rare, haploid, lichen-forming fungi Bryoria capillaris, B. fuscescens, and B. implexa are associated with boreal forests and belong to Bryoria sect. Implexae. Recent phylogenetic studies consider them to be conspecific. Microsatellite loci were developed to study population structure in Bryoria sect. Implexae and its response to ecosystem disturban...

With the frequency version of Moore’s law coming to an end, a new generation of massively multi-core microprocessors is emerging. This has triggered a regain of interest for the so-called dataflow programming models in which one expresses computation-intensive applications as networks of concurrent tasks interacting through (and only through) unidirectional FIFO channels. Our main result is a l...

Alternaria spp. from sect. Alternaria are frequently associated with hypersensitivity pneumonitis, asthma and allergic fungal rhinitis and sinusitis. Since Alternaria is omnipresent in the outdoor environment, it is thought that the indoor spore concentration is mainly influenced by the outdoor spore concentration. However, few studies have investigated indoor Alternaria isolates, or attempted ...

This chapter is organized according to a number of broad classes of problem where modular robotic systems can prove beneficial. For each such problem, the benefits of modularity are described, along with the ways that particular systems or proposed systems have explored those benefits. In particular, we discuss locomotion in Sect. 39.1, manipulation in Sect. 39.2, modular robot geometry in Sect...

First evidence of ηb was given in 2001 by ALEPH [1]. The search for ηb is done in the decay channel into two photons. One candidate event is found in the six–charged particle final state and none in the four–charged particle final state, giving the upper limits: Γ(ηb → γγ) × BR(ηb → 4 charged particles) < 48 eV , Γ(ηb → γγ) × BR(ηb → 6 charged particles) < 132 eV . This observation was the main...

Prunus subg. Prunus sect. Prunocerasus (Rosaceae) is a North American taxon with 17 commonly recognized taxa. To test the hypothesis of monophyly for the section we sequenced the trnG and rpL16 introns and the trnH-psbA and trnS-trnG intergenic spacers for at least two representatives of each of the five subgenera in Prunus. Additionally we sampled heavily among Prunus subg. Prunus sections Pru...

Several Central American species of Piper sect. Macrostachys have obligate associations with ants, in which the ant partner derives food and shelter from modified plant structures and, in turn, protects the plant against fungal infection and herbivory. In addition to these obligate ant-plants (i.e. myrmecophytes), several other species in Piper have resident ants only sometimes (facultative), a...

This paper presents an approach to multi-object image segmentation based on object motion using Markov Random Fields. To support the information gained from motion and to achieve robustness, several additional visual cues extracted from the image data are integrated. Depth information gained from stereo disparity is included to maintain segmentation in case an segmented object stops moving. Mot...
