Dihydrolevoglucosenone (CyreneTM) as a Bio-derived Liquid Organic Hydrogen Carrier.

Organic hydrides can store hydrogen via chemical bonding under ambient conditions, enabling the safe storage and transportation of hydrogen gas using the same infrastructure for gasoline. However, in previous research, most organic hydrides have been produced from petroleum, and therefore replacing them with earth-abundant or renewable compounds is essential to ensure sustainability. This study demonstrates dihydrolevoglucosenone (CyreneTM), which is a biodegradable liquid ketone that is produced directly from biomass without pretreatments on an industrial scale, as a new renewable organic hydride.

Registration system of cloud campus by using android smart tablet.

Near Field Communication (NFC) standard covers communication protocols and data exchange formats. NFC technology is one of radio-frequency identification (RFID) standards. In Japan, Felica card is a popular way to identify the unique ID.

Emergence of altruism behavior in army ant-based social evolutionary system.

Army ants perform the altruism behavior that an ant sacrifices its own well-being for the benefit of another ants. They build bridges using their own bodies along the path from a food to the nest. We developed the army ant inspired social evolutionary system by using Swarm library.

Comparison of proportional hazard model and neural network models in a real data set of intensive care unit patients.

There has been increased interest in using neural network model (NNM) for prognosis tasks. However, the performance of NNM has seldom been compared with that of traditional statistical models such as proportional hazard model (PHM) in real data sets. We conducted a comparative study of PHM and two types of NNM, that is, aggregate single point model (ASPM) and multiple point model (MPM), using a real data set of intensive care unit patients.
