Advanced analytical service science based on big data
Integrating big data and statistical mathematics for an individual-priority-based approach to analyze anddevise methods for improving the quality of business services and education environments.
Michiko Tsubaki is the UEC-vice-president responsible for public relations and an expert in statisticalmathematics conducting research on innovative analytical approaches for improving the quality of service
industries and education. "At junior high school I enjoyed both mathematics and Japanese literature," says
Professor Tsubaki. "Inspiring teachers enabled me to excel in both subjects. I particularly enjoyed readingbooks by novelist Sōseki Natsume, whose classics include I am a Cat and Botchan. Later, having finishedreading all of the works of Sōseki Natsume, I knew that he had the opportunity to read the book "the grammarof science" which was written by English statistician, Prof. Karl Pearson, in London. Sōseki ' s works on
novels and "the theory of literature" affected by Karl Pearson, really left an impression on me. This experience
was a major turning point in my life, and eventually led to my decision to go into the sciences, and appliedmathematics."
Professor Tsubaki is currently pursuing research into the improvement of the quality and co-creation of newvalues in service industries, as well as the education environment and learning capabilities of young people.
This research reflects the fact that the service sector accounts for 70% of Japan's GDP. Notably, Professor
Tsubaki's research is based on the application of her unique analytical system for measuring the effectivenessof a specific service based on individual customer types. "Our analytical system enables us to ascertain theindividual needs of a wide range of customers," explains Professor Tsubaki. "The strength of our analysis lies
in its ability to match the heterogeneous needs of both customers and service providers. We provide industrial
partners with quantitative analysis on methods to improve customer satisfaction and the quality of services forindividual customers with specific demands."
In the case of customers shopping in a supermarket, the analytical system classifies customers into several
types; determines the relationship between the objective and explanatory variables; analyzes the effectivenessof service by type; and compares the common factors at two different times.

Research highlights
Emotion hierarchy diagram (EHD) for designing specific order-made service processes
Research shows that customers who receive high quality service at coffee shops are more likely to become
regular customers--so called repeaters. Satisfied customers will spread the word of their experience--good orbad--by word of mouth. So needless to say, it is imperative for the success of such businesses to analysis
customer preferences and design processes to provide highly valuable services.
Here, Professor Tsubaki and colleagues decompose and analyze abstract emotions such as 'excitement' todesign specific, customer orientated high quality service processes. Examples of emotions and elements of
excitement in a café include: excitement of studying/café where customers can work without being disturbed;
excitement of using new things/ café where robots serve customers; and excitement of experiencing theextraordinary/ café with Indian décor and movies.
Big Data based analysis of relationships between customers and service providers
It's intuitive to think that customer satisfaction is an important factor affecting the sales of businesses. In orderto analyze this premise, Professor Tsubaki is using 'big data' from a major Japanese company that specializes
in providing carpet and other such cleaning services to determine whether company sales could be improvedby assigning one company rep to one customer--that is, matching the needs of customers and service providers.
Another goal of the research is to clarify the link between job satisfaction amongst company employees andcompany sales. Initial results based on data from one of the many branches of the cleaning company show that

both one-to-one customer-sales rep relationships and employee satisfaction do indeed lead to improvements inthe sales of the company.
Education and learning
The analytical system is also being applied for improving education and teaching. In one project, Professor
Tsubaki is looking into simultaneity and heterogeneity, with the assumption that teaching and learning occur
simultaneously and that students are from diverse and wide ranging backgrounds. Initial findings show thatthe 'learning style' is an important factor for the improvement of learning ability. Now, we study theclassification of Students into types based on the critical thinking skills, and Modeling for improvement ofEnglish abilities of elementary school students based on the analysis of log data of learning process.

Bose-Einstein condensates miscibility properties reveal surprises
Bose-Einstein condensates (BECs) are macroscopic systems that have quantum behaviour, and are useful for
exploring fundamental physics. Now researchers at the Gakushuin University and the University ofElectro-Communications have studied how the miscibility of multicomponent BECs affects their behaviour,with surprising results.
Fundamental particles have a property associated with angular momentum described as spin. Force particles photons, gluons, and so on - have integer spin values and are called bosons; matter particles - electrons,
neutrons, protons, and so on - have half integer values of spin and are called fermions. In composites ofseveral fermions, as in atoms and nuclei, the total spin can be integer values so they can behave as bosons.
While identical fermions cannot occupy the same state, bosons can, and if cooled to sufficiently low
temperatures they will all occupy the lowest possible energy state - a Bose-Einstein condensate.
The researchers studied a BEC of rubidium atoms exploiting the element's rich spin states. They created
optical traps containing around 3 x 105 atoms in two different spin states, and applied magnetic-field gradientpulses to separate condensates with different spins. The miscibility of different components of a BEC isdetermined by the strength of interactions between and within the atoms, which the researchers could tune to
produce miscible and immiscible multicomponent BECs.
After removing the magnetic field they left the system to evolve before releasing from the trap and imaged theresulting condensate distribution. "The various counterintuitive effects such as mutual penetration in
immiscible BECs, bouncing between miscible BECs, and domain formation in miscible BECs wereobserved," report the researchers. Numerical simulations of the system revealed further insights, showing that"the properties of penetration and bouncing can be tuned by slightly changing the atomic interaction
strengths."

Brain diseases: Unlocking potential from MRI data
Magnetic resonance imaging (MRI) plays a vital role in medical and neuroscience research as a non-invasive,highly sensitive way of imaging both physical structures and activity inside the human brain. The data fromeach MRI scan contain a vast amount of information, which is divided up into a three-dimensional gridcomprising individual 'voxels'.
Comparing individual voxel signals in a healthy subject with corresponding individual voxel signals in apatient can help uncover areas of the brain significant for specific diseases, for example. However, this'univariate' analysis can lose valuable information stored in patterns between multiple voxels.
Yoichi Miyawaki at the University of Electro-Communications in Tokyo reviewed recent progress in the fieldof 'multivariate' MRI analysis, exploring its potential in the fields of medical imaging and neuroscience1.
'Pattern classification models' can be trained to find signal patterns associated with specific diseases, such as
Alzheimer's or autism, which have complex neural signatures. When presented with a new MRI signal, themodel can classify it - an invaluable tool for medical diagnostics. Fine-tuning the models' ability to read
dynamic neural signatures could revolutionise the study of highly complex conditions like schizophrenia.
The high sensitivity of pattern classifiers means that they pick up finer details at the sub-voxel level. Recent
studies have shown that the models can reproduce visual images from signals generated in a person's brain
when they look at a picture - this could one day be expanded to explore hallucinations in schizophrenia andpost-traumatic stress disorder.
Advances in multivariate MRI analysis could also lead to better brain-machine interfaces for motor-paralysis
patients.

Auditory systems: Modelling bats' information processing
An intriguing aspect of auditory signal processing is that certain creatures can tune in to specific frequencies
relevant to behavior - such as for hunting or survival - while filtering out all other 'noise'. Scientists know that,while sensory information is transmitted from the ears to the cerebral cortex in a 'feedforward' manner, theinformation is also modulated by feedback from the cerebral cortex itself. Cortical neurons are excited byrelevant signals, and tell the peripheral neurons to hone in on them while at the same time reducing signals
from surrounding noise - a 'gating' mechanism, in other words. However, exactly how this process works is
unclear.
Kazuhisa Fujita and Yoshiki Kashimori at the University of Electro-Communications in Tokyo, Japan,
developed a neural network model of a bat's auditory system to examine how signal processing may be
modulated by feedback from the cerebral cortex1.
Bats hunt by echolocation, and this involves detecting the Doppler-shifted frequency of sound echoes (as prey
moves). Following feedback from cortical neurons, certain neurons in the auditory cortex are electricallystimulated by Doppler-shifted frequencies while others are not. This stimulation evokes synaptic modulationin neurons in the inferior colliculus (an area in the midbrain).
Fujita and Kashimori's model shows how an injection of GABA antagonist bicuculline methidide, or BMI,
suppresses signals from surrounding 'noise' picked up by other auditory neurons. The electrical stimulationfrom a relevant signal coupled with BMI enables the bats to balance activity in different neurons' receptive
fields.
Their model could help understand how bats rapidly discriminate between signals from edible insects andsurrounding background noise.

Insights into musicology: Role played by sensory information in the acquisitionand execution of advanced skills.
"Experiences of entrance exams for music school, and learning and teaching the piano led me to realize thatdifferent people hear the same music in different ways," says Eriko Aiba, assistant professor at the Graduate
School of Informatics and Engineering, UEC, Tokyo. "Our sensory interpretation of the sound of a chord ofmusic is unique, with some people hearing specific notes clearly, whilst others sense more unified sounds.
Understanding these sensory reactions to music is the main aim of my research activities.
This research is ongoing, and in the future the results of this research will be applied to devising methods ofteaching children how to reach their full potential in many different fields including music.

Main topics of research
Development of auditory sense by learning from human physical skills
The goal of this research is to clarify the relationship between musical performance and processing of sensory
information with emphasis on verifying the necessity of focusing on not only sound, but also training based on
both sound and active exercise. This research is expected to lead to methods for improving word legibility inage-related hearing loss [1-2].
Movement strategy based on prioritization of sensory information
This project aims to elucidate how the brain processes information in response specific playing strategies. A
major goal is to clarify the relationship between performance and memory when musicians play music [3-4].

Quantum physics: Superfluidity of helium in one dimension"My fascination with physics was sparked by an excellent science teacher at school," says Junko Taniguchi,
assistant professor at the Department of Engineering Science. "At university I was initially tempted to pursue
chemistry, but I became interested in the concept of quantum physics, wave functions, and superfluidity that
led to my current research, which is an experimental application of wave functions. One dimensional
superfluity is a challenging and fascinating area of research. I am studying the mysterious changes in the stateof helium (4He) at low temperatures when the substance is confined to move in only one dimension."

Recent research highlights
In the three dimensional macroscopic world, Helium (4He) shows strong quantum effects and does not freeze
at absolute zero but instead changes from a gas, to a liquid, and finally a superfluid--a liquid state where it
flows without viscosity. But what happens if 4He is confined to one dimensional? Theory predicts that thesuperfluidity should appear in 1D.
Here, Junko Taniguchi and her colleagues constructed dedicated 'double torsional oscillators' toexperimentally test samples of 4He confined inside 2.8 nm diameter pores formed inside Folded Sheets
Mesoporous materials (FSM). "Our so-called frequency dependent experiments agreed with theoreticalpredictions and we detected superfluidity in pore diameters larger than 2.8 nm," says Professor Taniguchi.
"Our findings are a major breakthrough in superfluidity."
Future plans include verifying the theoretically predicted power-law frequency dependence of superfluidity
using a new frequency variable torsional oscillator that is currently under construction, and the search for theorigin of two stage growth, again using a specially designed 'superfluid detector that is composed of a
Helmholtz resonator.

Japanese onomatopoeia: Mathematical models to analyze Japanese phonemes
and associated images
The Japanese language is a treasure trove of onomatopoeia, with words such as 'kira-kira' conjuring up vivid
images of 'twinkling' objects. Here, Maki Sakamoto is analyzing links between Japanese onomatopoeia andsensory experiences.

Research highlights
Vision and sound symbolism
Could onomatopoeia be used to evaluate the texture of metals and differentiate between real and imitation
metal textures? Participants are shown real and imitation metals and asked to describe the nature of thematerials they see using words from a list of onomatopoeia Clear differences in onomatopoeia for real andimitation metals were found. Applications of this research include the design of metal textures for automobiles
and other such industrial areas [1].
Taste and sound symbolism
The goal is to quantify relationships between onomatopoeia and taste/texture. In experiments, participants
express their sense of taste of liquids including milk and sports drinks, using Japanese onomatopoeia. Results
show the sensation of tasting to result in primarily of 'clusters' of words like pleasant/unpleasant [2].
Medicine and sound symbolism
Medical doctors and patients in Japan use onomatopoeia to communicate. Here, the aim is to develop a systemthat automatically suggests metaphors related to onomatopoeia selected by patients [3].

Biophotonics: Using light sensitive proteins as artificial retinas
The light sensitive receptor protein, bacteriorhodopsin (bR) is readily extracted from the cell membrane of
Halobacterium salinarum--rod shaped organisms that give the purple color to the water of salty lakes. Since
the discovery of bR pigments in the early 1970s, it has been used by scientists for studying the functions ofcells, as well applications in nanophotonics.
Now, Yoshiko Okada-Shudo, associate professor at the Graduate School of Informatics and Engineering, is
exploiting the optical properties of bR for the development of biophotonic devices and systems for real-life
applications.
Future plans include combining bR based optical filters and high speed image processing for detecting defects
in electronic circuits and quality control in industrial manufacturing.

Research highlights
Bacteriorhodopsin based artificial retina-motion sensors for robot visionThis project is focused on the development of single element human-eye-like photocell based systems formotion detection. Initial tests with autonomous maze-navigating robots showed promise for robot visionapplications with a robust response to rapidly moving objects [1].
Bacteriorhodopsin proteins for innovative filters for receptive fields
The goal of this research is the development of patterned Gabor and DOG optical filters for improving theimage processing performance of receptive fields. Notably, the low cost and simplicity of fabricating single
element bR filters, and no requirement for external connections are two of the major advantages overconventional silicon semiconductor technology [2].

Special seminar on atmospheric physics by Dr Chiao-Yao She, Emeritus
Professor of Colorado State University, USA.
Dr Chiao-Yao She shared his insights into the measurement and implications of atmospheric temperature andwind velocities in his seminar entitled, "LIDAR capability for atmospheric temperature and windmeasurements and enabled MLT science studies".
In Lidar (Light Detection and Ranging) a powerful laser light is irradiated upwards into the earth's atmosphereand the scattered light collected by sensitive detectors on earth to analyze the metallic composition,
temperature, and wind velocity of specific layers of the atmosphere. Notably, UECs Takuo Tsuda, assistantprofessor at the Department of Computer and Network Engineering, who organized the seminar, is an expert
on Lidar studies of the properties of metals such as sodium and potassium found at around 100 km above theearth's surface due to meteors breaking apart as they enter the atmosphere.
Dr She explained the physical principles of Lidar highlighting his own approach in the development of his
own unique Lidar systems for the analysis of light scattering spectra for the measurement of atmospherictemperature and wind velocity.
According to Dr She, in the early days of his research it was only possible to detect scattered light at night but
development of methods based on narrow band filters for exclusion of optical noise from sunlight led to therealization of continuous measurements over 24 hours at regions between 80 km to 105 km.
Dr She finished his seminar by giving his vision of future trends in atmospheric research. After the seminar Dr
She joined the audience for a lively discussion about the topics covered during the seminar.

The University of Electro-Communications (UEC) in Tokyo
is a small, luminous university at the forefront of applied sciences, engineering, and technology
research. Its roots go back to the Technical Institute for Wireless Commutations, which wasestablished in 1918 by the Wireless Association to train so-called wireless engineers in maritime
communications in response to the Titanic disaster in 1912. In 1949, the UEC was established as anational university by the Japanese Ministry of Education, and moved in 1957 from Meguro to its
current Chofu campus Tokyo.
With approximately 4,000 students and 350 faculty, UEC is regarded as a small university, but withparticular expertise in wireless communications, laser science, robotics, informatics, and materialscience, to name just a few areas of research.
The UEC was selected for the Ministry of Education, Culture, Sports, Science and Technology (MEXT)
Program for Promoting the Enhancement of Research Universities as a result of its strengths in threemain areas: optics and photonics research, where we are number one for the number of joint
publications with foreign researchers; wireless communications, which reflects our roots; andmaterials-based research, particularly on fuel cells.
