Carotenoids are the precursors of important fragrance compounds in flowers of Osmanthus fragrans Lour. var. aurantiacus, which exhibit the highest diversity of carotenoid-derived volatiles among the flowering plants investigated. A cDNA encoding a carotenoid cleavage enzyme, OfCCD1, was identified from transcripts isolated from flowers of O. fragrans Lour.(More)
We introduce the organization of the Todai Robot Project and discuss its achievements. The Todai Robot Project task focuses on benchmarking NLP systems for problem solving. This task encourages NLP-based systems to solve real high-school examinations. We describe the details of the method to manage question resources and their correct answers, answering(More)
During the maturation of snake fruit (Salacca edulis Reinw) Pondoh, the contents of sucrose, glucose, fructose, and volatile compounds changed drastically. The glucose, fructose, and volatile compounds contents showed their maximum levels at the end of maturation; however, the sucrose content decreased. During maturation, the flesh firmness tended to(More)
We developed and validated a new high-performance liquid chromatographic analysis for electrochemically detecting guaiacol and vanillin as important components in vanilla extract. Separation was achieved with Capcell Pak C-18 MG, the potential of the working electrode being set at +1000 mV. The respective calibration curves for guaiacol and vanillin were(More)
This paper investigates multiple wheeled mobile manipulators coordinating with each other for a common task such as transporting a common object. In our previous work we derived kinematic and dynamic manipulability measures for multiple mobile manipulators transporting a common object and also developed a simulation environment. The main objective of this(More)
The NTCIR-12 QA Lab-2 task aims at the real-world complex Question Answering (QA) technologies using Japanese university entrance exams and their English translation on the subject of " World history ". The exam questions are roughly divided into multiple-choice and free-description styles, and have various question formats, which are essay, fac-toid,(More)
A lightweight, human-in-the-loop evaluation scheme for machine translation (MT) systems is proposed. It extrinsically evaluates MT systems using human subjects' scores on second language ability test problems that are machine-translated to the subjects' native language. A large-scale experiment involving 320 subjects revealed that the context-unawareness of(More)
Yuzu ( Citrus junos Sieb. ex Tanaka), a tree-grown fruit similar to a kind of sour orange, is widely used in Japanese food/cooking for its pleasant flavor. To clarify the odor-active volatiles that differentiate yuzu from other citrus fruits, sensory evaluations were conducted on yuzu peel oil. The results revealed that the polar part of yuzu peel oil was(More)
Green algae are of great economic importance. Seaweed is consumed fresh or as seasoning in Japan. The commercial value is determined by quality, color, and flavor and is also strongly influenced by the production area. Our research, based on solid phase microextraction gas chromatography mass spectrometry (SPME-GC-MS), has revealed that volatile compounds(More)
The odor-active volatiles of Kinokuni mandarin (Citrus kinokuni Hort. ex Tanaka), an original mandarin orange in Japan, were characterized by a combination of instrumental and sensory analyses and compared with those of Satsuma mandarin (Citrus unshiu Marcovitch). An aroma extract dilution analysis (AEDA) of the polar fractions of Kinokuni and Satsuma(More)
