A research group, including Emeritus Professor Tsuneo Nitta, Professor Junsei Horikawa, and Assistant Professor Shunji Sugimoto at Toyohashi University of Technology along with Associate Professor Koichi Katsurada of Tokyo University of Science, has developed a technology that can recognize the numbers 0 to 9 with 90% accuracy using brain waves, or electroencephalogram (EEG), while uttering the numbers. Furthermore, the technology has also realized the recognition of 18 types of Japanese monosyllables from EEG signals with 60% accuracy, which shows the possibility of an EEG-activated typewriter in the near future. The details of this research will be presented at Interspeech 2017 held in Stockholm in August. http://www. The research group has collected EEG-data while uttering Japanese digits and monosyllables. Regarding these data, the group investigated digit and monosyllable recognition experiments. Up until now, speech-decoding from EEG signals has had difficulty in collecting enough data to allow the use of powerful algorithms based on 'deep learning' or other types of machine learning. The research group has developed a different research-framework that can achieve high performance with a small training data-set. The new framework is based on holistic pattern recognition using category theory, or composite mapping, in which a dual space and a tensor space including exterior algebra are introduced. In the experiment of spoken-digit recognition from EEG signals, 90% recognition accuracy was achieved. At the same time, 61% accuracy in 18 Japanese monosyllable recognition was achieved outperforming performance in previous research (humans have sufficient intelligibility of sentences with an 80% monosyllable recognition rate). Emeritus Professor Nitta and his group aim to develop a 'Brain Computer Interface' that recognizes utterances without voicing, or speech imagery. This technology may enable handicapped people, who have lost the ability of voice-communication, to obtain the ability once again. It is also expected that the technology would give a healthy person the most natural interface without any limitations as well. Furthermore, the research group plans to develop a device that can be easily operated with fewer electrodes and connected to smartphones within the next five years. This research was funded by the Ministry of Education, Culture, Sports, Science and Technology and the Japan Society for the Promotion of Science Research Grant 16K00251. We will hold a press conference on April 18 to present the details of this research at Toyohashi University of Technology.

We investigate the influence of the isospin asymmetry on the phase structure of quark matter near the chiral critical point systematically using a generalized version of Ginzburg-Landau approach. The effect has proven to be so profound that it brings about not only a shift of the critical point but also a rich variety of phases in its neighborhood. In particular, there shows up a phase with spatially varying charged pion condensate which we name the "solitonic pion condensate" in addition to the "chiral defect lattice" where the chiral condensate is partially destructed by periodic placements of two-dimensional wall-like defects. Our results suggest that there may be an island of solitonic pion condensate in the low temperature and high density side of QCD phase diagram. © 2013 The Author.

Understanding the factors that promote drug innovation is important both for improvements in health care and for the future of organizations engaged in drug discovery research and development. By identifying the inventors of 252 new drugs approved by the US Food and Drug Administration from 1998 to 2007 and their places of work, and also classifying these drugs according to innovativeness, this study investigates the contribution of different types of organizations and regions to drug innovation during this period. The data indicate that drugs initially discovered in biotechnology companies or universities accounted for approximately half of the scientifically innovative drugs approved, as well as half of those that responded to unmet medical needs, although their contribution to the total number of new drugs was proportionately lower. The biotechnology companies were located mainly in the United States. This article presents a comprehensive analysis of these data and discusses potential contributing factors to the trends observed, with the aim of aiding efforts to promote drug innovation. © 2010 Macmillan Publishers Limited.

This paper is a review of new developments in the experimental field of the efficient emission of the positronium negative ion, a bound state of one positron and two electrons, from alkali-metal coated surfaces. Following the prediction of its existence by Wheeler in 1946, this ion has been one of the most attractive subjects for theorists to investigate in the field of positron physics, resulting in a large number of studies. Though the first observation of the ions, formed using a carbon thin film, was made in 1981 by Mills, there have been few experimental works since, limited by the low-production efficiency achievable for nearly 30years. In 2008, a dramatic effect on the ion emission from tungsten surfaces was discovered upon coating it with Cs. This has opened the door to a new era of experimental investigations of this ion. This paper reports the investigations performed so far. Advances discussed include efficient formation of the ion, its photodetachment and the production of an energy-tunable positronium beam based on the technique of the photodetachment. © 2014 Elsevier B.V.

Water splitting to produce H 2 using sunlight is a form of artificial photosynthesis in that light energy is converted to chemical energy. As such, water splitting using powdered photocatalysts has attracted attention in the framework of energy and environmental issues. This article reviews z-scheme photocatalyst systems for water splitting under visible light irradiation, especially focused on the systems consisting of SrTiO3: Rh of a H2-evolving photocatalyst, and O2-evolving photocatalysts with and without electron mediators. These photocatalyst systems showed activities for water splitting into H2 and O2 in a stoichiometric amount under visible light irradiation and even under sunlight irradiation. The photocatalytic activity was sensitive to pH. The optimum pH was 2.4 when iron ions were used as electron mediators. Co-catalysts also affected the activity. The photodeposited Ru co-catalyst gave an excellent performance. The best performance achieved by the pH adjustment and the selection of a co-catalyst was obtained mainly by suppression of back reactions to form H 2 O from evolved H2 and O2. © 2011 Materials Research Society.

This tutorial review covers SmI2-induced reductive cyclizations of β-alkoxyacrylate, β-alkoxyvinyl sulfone, and β-alkoxyvinyl sulfoxide, as methods for efficient construction of cyclic ethers. These cyclizations were developed as tools to aid in the total synthesis of marine polycyclic ethers, whose complex, synthetically challenging structures and potent bioactivities have attracted the attention of numerous synthetic organic chemists. Applications of the methods to total syntheses of various natural products containing cyclic ether are also described. © The Royal Society of Chemistry 2010.
