[Quake-Resistant Ground Materials]
Development of Recycling Technology for High-Water Content Sludge by Using Fiber MaterialsFeaturesThe recycling rate of construction muds and sludge is very low because the water content of these muds is very high and direct reuse of them is very difficult. Therefore, a new recycling technology for high-water content sludge has been developed in this laboratory. This technology is called "Fiber-Cement-Stabilized Soil Method", and it uses fiber materials and cement. The main feature of this method is to mix the fiber materials with the sludge, and the fiber materials included in the soil produce several geotechnical merits. Targeted Application(s)/IndustryThe modified soils produced by this method can be used as ground materials for reinforced embankment of the river bank and soil structures because they have several features such as high failure strength, high failure strain high durability for drying and wetting and high dynamic strength.

[Quantification Method]
Development of a Novel Quantification Method for Diarrhetic Schell Fish PoisoningFeaturesWe have investigated isolation and structure determination of natural products and evaluated mode of their actions. We have especially focused on marine natural products causative for a food poisoning, diarrheic shellfish poisoning (DSP), which has spread worldwide and threatened regional fishery industry. Dinophysistoxin produced by the dinoflagellate Dinophysis spp. and okadaic acid, are thought to be responsible for DSP. Acute toxicity test using mice has been the primary method for detection of DSP in the fish market, though an alternative method to quantify DSP without sacrificing mice has been requested. We isolated OABP2, a novel okadaic acid binding protein, from the marine sponge Halichondria okadai and succeeded in expression of the recombinant OABP2 in E. coli, which eventually showed high affinity to the DSP toxins. Targeted Application(s)/IndustryWe are now working on visualization of OA by utilizing OABP2 in order to provide an easy and quick quantification method for DSP. |

Optimizing everything / Optimal SocietyFeaturesAiming at developing practical quantum optimization technology known as quantum annealing, we are working on exploring basic technologies that can overcome the limitations and applications in collaboration with multiple companies. The advantage of the method is that it can be used simply by formulating a cost function that draws the goal to be optimized once, but we are not limited to the original method. We extend it by considering a much easier problem, sequential optimization by learning, black box optimization, etc.. In particular, it is being applied to automated driving, logistics in factories, and evacuation guidance during disasters. Targeted Application(s)/IndustryApplications to route search problems such as automatic driving of various vehicles, evacuation route guidance at the time of disaster, process scheduling and a large number of combination problems.
