Distributed computing continues to be an alphabet-soup of services and protocols for managing computation and storage. To live in this environment, applications require middleware that can transparently adapt standard interfaces to new distributed systems; such software is known as an interposition agent. In this paper, we present several lessons learned about interposition agents via a progres...
One hundred prisoner cichlid fish, (2.5 g), were fed with levels 1, 2 and 3 grams of prebiotic inulin per kg of diet over a period of 60 days. The highest weight gained in treatment 3 g of inulin, which was not significantly different from treatment 2 g of prebiotic dietary (P>0.05). The highest specific growth rate was measured in 2 and 3 g inulin. The highest feed conversion ratio and the h...
The article presents the first Ukrainian translation as well a detailed historical and literary analysis of cycle Ten partings (“十離詩”) written by Xue Tao (薛濤, 768–832), one “Four Greatest Female Shi Poets Tang Dynasty” (“唐代四大女詩人”). This can be dated back to 789 or 809. It consists ten quatrains, which is “ancient style poetry” gutishi (古體詩) while others are “modern jintishi (近體詩). A has shown t...

Most docking methods involving a small robot and a station require the docking station to communicate with the robot. Few robots are able to dock with a passive base station. Even fewer can also be “driven” by a bird. This paper presents a novel way for parrot-guided transportation and autonomous docking using range lights and a web camera.
Our CoBot robots have successfully performed a variety of service tasks in our multi-building environment including accompanying people to meetings and delivering objects to offices due to its navigation and localization capabilities. However, they lack the capability to visually search over desks and other confined locations for an object of interest. Conversely, an inexpensive GPS-denied quad...
1. The osmotic ratio between ' urine' (the supernatant of the ureteral part of the droppings) and plasma has been determined in a number of dehydrated West Australian birds. 2. The U/P ratio was 1-4 in the Emu, 1*7 in two Columbidae (Senegal Turtle Dove and Crested Pigeon), 2-4 in two Meliphagidae (Singing Honeyeater and Red Wattle Bird), 2-6 in three Psittacidae(Bourke Parrot, 28-Parrot, and G...
Female mate choice has often been proposed to play an important role in cases of rapid speciation, in particular in the explosively evolved haplochromine cichlid species flocks of the Great Lakes of East Africa. Little, if anything, is known in cichlid radiations about the heritability of female mating preferences. Entirely sympatric distribution, large ecological overlap and conspicuous differ...
Learned birdsong is a widely used animal model for understanding the acquisition of human speech. Male songbirds often learn songs from adult males during sensitive periods early in life, and sing to attract mates and defend territories. In presumably all of the 350+ parrot species, individuals of both sexes commonly learn vocal signals throughout life to satisfy a wide variety of social functi...
Our objective was to determine the effect of lead (Pb) on behavior Mexican mojarra, which is native Balsas River basin, and convict cichlid, an exotic invasive there. Both fish species were exposed Pb, followed by Pb depuration, evaluate its impacts behavior. We evaluated swimming activity, predation attempts, prey consumed, foraging efficiency, aggressive behaviors. The behavioral effects diff...
