Let G be the universal cover of the group of automorphisms of a symmetric tube domain and let P = L N be its Shilov boundary parabolic subgroup. This paper attaches an irreducible unitary representation of G to each of the (finitely many) L-orbits on n*. The Hilbert space of the representation consists of functions on the orbit which are square-integrable with respect to a certain L-equivariant...

We consider the following question: given A ∈ SL(2,R), which potentials q for the second order Sturm-Liouville problem have A as its Floquet multiplier? More precisely, define the monodromy map μ taking a potential q ∈ L2([0, 2π]) to μ(q) = Φ̃(2π), the lift to the universal cover G = ̃ SL(2,R) of SL(2,R) of the fundamental matrix map Φ : [0, 2π] → SL(2,R), Φ(0) = I, Φ(t) = (

Castor bean (Ricinus communis L.) is one of the most important non-edible oilseed crops. Characterization of seed development and lipid accumulation from female flowers pollinated to mature seeds has been carried out. The temporal expression patterns of 65 lipid genes involved in fatty acid and triacylglycerol biosynthesis using the semi-quantitative RT-PCR technique were also investigated. The...

A cyst nematode, Heterodera goldeni n. sp., is photographed and described from Qasabagrass roots (Panicum coloratum L.) in Alexandria, Egypt. It is characterized in having second-stage juveniles with body length of 546 microm (450-612), stylet length of 22.6 microm (22-23.5) with anchor-shaped knobs, lateral field with 3 lines, tail 60-75 microm, hyaline tail terminus 38.4 microm (33-43); cysts...

Ever-increasing demand for water to irrigate crops, support aquaculture, provide domestic water needs and to protect natural aquatic and riparian habitats has necessitated research to reduce impacts from a parallel increase in invasive aquatic weeds. This paper reviews the past 4-5 years of research by USDA-ARS covering such areas as weed biology, ecology, physiology and management strategies, ...

Covering crops was a commonly used viticultural technique to adjust the vineyard microclimate, thus affecting grape and wine quality. In this two-year study, purslane (Portulaca oleracea L.) cover lands between rows in vineyards located semi-arid Northwest China, Xinjiang. Results showed that photosynthetically active radiation around fruit zone temperature with covering treatment decreased. Co...

In a scenario where two UAS can benefit from cooperation, but where one of the UAS is non-cooperative and only broadcasting very limited state information, there is a need for the second UAS to estimate the intentions of the first UAS. When the second UAS is capable of this they will be able to solve joint tasks faster even though the cooperation is only ”one way”. In this work we investigate a...

Plastic covering is used worldwide to protect crops against damaging growing conditions. This agricultural practice raises some controversial issues. While it significantly impacts on local economic vitality, plasticulture also shows several environmental affects. In the Apulia Region (Italy) the wide-spreading of artificial plastic coverings for vineyard protection has showed negative conseque...

The agriGO platform, which has been serving the scientific community for >10 years, specifically focuses on gene ontology (GO) enrichment analyses of plant and agricultural species. We continuously maintain and update the databases and accommodate the various requests of our global users. Here, we present our updated agriGO that has a largely expanded number of supporting species (394) and data...

Second-generation sequencers (SGS) have been game-changing, achieving cost-effective whole genome sequencing in many non-model organisms. However, a large portion of the genomes still remains unassembled. We reconstructed azuki bean (Vigna angularis) genome using single molecule real-time (SMRT) sequencing technology and achieved the best contiguity and coverage among currently assembled legume...
