Nucleotide sequences from the P1 gene and the 5′ untranslated region of leek yellow stripe virus (LYSV), collected from several locations, were used to refine the phylogenetic relationships among the isolates. Multiple alignments revealed three distinct regions of insertions and deletions to classify LYSVs. In our phylogenetic analyses, the LYSV isolates(More)
Escherichia coli as a plasmid recipient cell was dispersed in a chrysotile colloidal solution, containing chrysotile adsorbed to plasmid DNA (chrysotile-plasmid cell mixture). Following this, the chrysotile-plasmid cell mixture was dropped onto the surface of an elastic body, such as agarose, and treated physically by sliding a polystyrene streak bar over(More)
This paper proposes an interactive attraction system, "Groveling on the Wall," which provides an experience of groveling on the walls/ceilings of a virtual building with a gravity illusion (Figure1). To create a gravity illusion for the system, which is safer than real experiences, we developed two physical mechanisms: the groveling interface and the(More)
This paper proposes an interactive manager agent system that adjusts schedule among multiple persons through negotiations on behalf of a human organizer, such as a steward or team manager. In order to increase the users' cooperative decision-making, we implemented the manager agent that negotiates with each member on the schedule using 1) the suitable(More)
—Obtaining a survival strategy (policy) is one of the fundamental problems of biological agents. In this paper, we generalize the formulation of previous research related to the survival of an agent and we formulate the survival problem as a maximization of the multi-step survival probability in future time steps. We introduce a method for converting the(More)
We introduce a virtual ski jump system as indoor, experience-based entertainment. The goal of this system is an exciting, enjoyable, safe experience for an inexperienced person. The key of the system is the physical stimuli from below for realistic experience compared to other conventional systems. First, the variation of slope angle creates the illusions(More)
Fresh Geobacillus thermoglucosidasius cells grown on soybean-casein digest nutrient agar were inoculated as a parent colony 1 cm in diameter on the surface of an agar gel containing acetate and calcium ions (calcite-promoting hydrogel) and incubated at 60 °C for 4 days, after which magnesium-calcite single crystals of 50–130 µm in size formed within the(More)
