The thirteenth AAAI Mobile Robot Competition and Exhibition was held last July, in conjunction with the Nineteenth National Conference on Artificial Intelligence (AAAI 2004), in San Jose, California. The primary purpose of the Mobile Robot Competition and Exhibition is to bring together researchers and students from academe and industry to showcase the latest state-of-the-art mobile robot capab...

background:in the recent decade, the reverse genetics method has been broadly used for rescue of negative-stranded rna viruses from cdna or viral minigenomes. this technique has been applied to study different steps in virus replication and virus-host interactions. reverse genetics could also be implemented for design of new vaccines. the t7 rna polymerase activity as well as virus (nucleocapsi...

This project aimed at breeding new seedless grape cultivars by embryo rescue through three hybridization methods: 1) using cross-breeding between seedless Vitis vinifera cultivars and wild Chinese Vitis spp; 2) crossing with two seedless cultivars, and 3) hybridization between grapes of different ploidy. Genotype, sampling times, and media were confirmed to play important roles in this system. ...

background: in this feasibility study, a mechanically loaded in-vitro tissue culture model of joint morphogenesis using the isolated lower extremity of the 8 day old chick embryo was developed to assess the effects of mechanical loading on joint morphogenesis. methods: the developed in-vitro system allows controlled flexion and extension of the chick embryonic knee with a range of motion of 20 ...

Formation of the dorsal-ventral axis of the sea urchin embryo relies on cell interactions initiated by the TGFbeta Nodal. Intriguingly, although nodal expression is restricted to the ventral side of the embryo, Nodal function is required for specification of both the ventral and the dorsal territories and is able to restore both ventral and dorsal regions in nodal morpholino injected embryos. T...

STUDY QUESTION Is severe early ovarian hyperstimulation syndrome (OHSS) completely prevented with the GnRH agonist trigger and 1500 IU hCG luteal rescue protocol? SUMMARY ANSWER Severe early OHSS can occur even after the GnRH agonist trigger and 1500 IU hCG luteal rescue protocol. WHAT IS KNOWN ALREADY Prior studies including over 200 women who received the GnRH agonist trigger and 1500 hCG...

Interspecific hybridization is an important method to widen variations and to develop novel cultivars. Interspecific cross-pollination was carried out among three species of Cucurbita (C. moschata, C. ficifolia and C. martinezii) as male parents with ten cultivars of C. pepo as female parents. Only four cultivars of C. pepo (Eskandarani cv., Queen F , Jedida F and MHTC77 F ) were successful in ...

Team pursuit track cycling is a bicycle racing sport held on velodromes and is part of the Summer Olympics. It involves the use of strategies to minimize the overall time that a team of cyclists needs to complete a race. We present an optimisation framework for team pursuit track cycling and show how to evolve strategies using metaheuristics for this interesting real-world problem. Our experime...
