The Rice Annotation Project Database (RAP-DB, http://rapdb.dna.affrc.go.jp/) has been providing a comprehensive set of gene annotations for the genome sequence of rice, Oryza sativa (japonica group) cv. Nipponbare. Since the first release in 2005, RAP-DB has been updated several times along with the genome assembly updates. Here, we present our newest(More)
The Rice Annotation Project Database (RAP-DB) was created to provide the genome sequence assembly of the International Rice Genome Sequencing Project (IRGSP), manually curated annotation of the sequence, and other genomics information that could be useful for comprehensive understanding of the rice biology. Since the last publication of the RAP-DB, the(More)
—Energy harvesting is a key technique that can be used to overcome the barriers that prevent the real world deployment of wireless sensor networks (WSNs). In particular, solar energy harvesting has been commonly used to overcome this barrier. However, it should be noted that WSNs operating on solar power suffer form energy shortage during nighttimes.(More)
This paper introduces a low cost, fast and accessible technology to support the rapid prototyping of functional electronic devices. Central to this approach of 'instant inkjet circuits' is the ability to print highly conductive traces and patterns onto flexible substrates such as paper and plastic films cheaply and quickly. In addition to providing an(More)
Massively multiplayer online games and other multiuser based networked applications are becoming a big business today. Such kind of technology has long been researched in the area called Networked Virtual Environments (Net-VE). With the recent deployment of broadband access technologies, the increase of the number of participants is putting pressure on the(More)
Understandings of human activity through wearable sensors will enable the next-generation human-oriented computing. However, most of researches on the activity recognition so far are based on small number of test subjects, and not well adapted for real world applications. To overcome the situation, we have started a project named "HASC Challenge" to collect(More)
This paper shows a methodology of estimating a user's everyday energy expenditure using a 3-axis accelerometer of a mobile phone handset. We first infer the user's posture based on the acceleration sensor reading and calculate METS value, which is considered as a measure for estimating calorie consumption for daily activities. The experimental result shows(More)
— " Smart " and " attentive " services using users' context are going to be realized in future ubiquitous computing environment. Sensor network is receiving considerable attention as one of the key technologies to keep track of the users' context in the real world. Conventional sensor network research mainly aimed at environmental monitoring. However(More)
Human activity recognition through the wearable sensor will enable a next-generation human-oriented ubiquitous computing. However, most of researches on the activity recognition so far are based on small number of subjects, and non-public data. To overcome the situation, we have formed a consortium named HASC and create corpora for the research community.(More)
Gene duplication occurs by either DNA- or RNA-based processes; the latter duplicates single genes via retroposition of messenger RNA. The expression of a retroposed gene copy (retrocopy) is expected to be uncorrelated with its source gene because upstream promoter regions are usually not part of the retroposition process. In contrast, DNA-based duplication(More)
