RECENT RESEARCH ACTIVITIES My research specialty is arithmetic geometry, which is a branch of algebra and reaches across algebraic geometry and number theory. In particular, I am interested in and have researched algebraic cycles, cohomology, cycle class mappings and Chern class mappings of arithmetic schemes. Recently I am working on the following projects:

1. Intuitive construction of motivic cohomology `extended by zeroʼ. This project aims to give an alternative definition of motivic cohomology with compact support defined by Suslin and Voevodsky.

2. Zeta-values of proper regular arithmetic schemes. For a proper regular arithmetic scheme X flat over Spec(Z), I aim to compute the value of the Research Interests Hasse-Weil zeta function ζ(X,s)/ ζK (s-d+1) at s=d, where d denotes dim(X) and K denotes the algebraic closure of Q in the function field of X. A possible  arithmetic geometry goal is to give a generalization of the analytic class number formula in the  algebraic cycles figure below, assuming Tamagawa number conjecture of Bloch-Kato.  cohomology theory  motivic cohomology  zeta functions

RECENT RESEARCH ACTIVITIES I began my research career with study on algebraic geometry in positive characteristic and in mixed characteristic.

My main research interest for long periods is description of finite coverings of an algebraic variety over a field of positive characteristic or a discrete valuation ring of mixed characteristics. Especially, I studied the theory unifying the Kummer theory in characteristic 0 and the Artin-Schreier-Witt theory in positive characteristic in the framework of the Cartier theory on formal groups, constructing needed infrastructures. As by-products, I could establish several results on torsors under finite flat group schemes, for example, Kummer theories for algbraic tori.

Recently, I have gotten a surprising application of my method to the divisibility Research Interests problem for Lucas sequences, including the Fibonacci sequence. I expect that my recent work gives a new aspect to this area, where has left an enormous  Finite Flat Group accumulation of research. Scheme  Torsor

RECENT RESEARCH ACTIVITIES

I have been interested in the topology of various symplectic quotients, such as the ones associated to a direct product of several coadjoint orbits of a compact Lie group. My approach is based on the observation that the topology and geometry of such symplectic quotients is closely related to the irreducible (and weight) decomposition of a tensor product of irreducible representations of the Lie group. More concretely, I have been studying several procedures to compute the characteristic numbers and the symplectic volume, and applied them to the study of the topological and geometric structure of the symplectic quotients.

On the other hand, the theme as above is Research Interests closely related to the theory of convex polytopes, which considers, for example, the number of the  Topology and geometry integral points and the volume of a convex of symplectic quotients polytope. It has a connection with the theory of  The number of integral hypergeometric functions, too. points and the volume of convex polytopes

RECENT RESEARCH ACTIVITIES I am interested in the study of nonlinear dispersive equations by the harmonic analysis. Nonlinear dispersive equations, for instance, nonlinear Schrodinger equations, the Korteweg-de Vries equation and the Zakharov system appear in physic and engineering. The well-posedness (uniqueness existence of the solution and continuous dependence on initial data) of the Cauchy problem is the most fundamental problem. However, it is not easy to solve when the nonlinearity of the equation has a strong singularity. To control the singularity, we need to employ some tools related to special structures or properties of the equations.

Research Interests RECENT RESEARCH ACTIVITIES I am interested in well-posedness for hyperbolic partial differential equations, especially wave equations and the Kirchhoff equation. Analytic well-posedness for the Kirchhoff equation was proved by Sergey Bernstein, a Russian mathematician in 1940. Since then, many authors have extended his work to multidimensional spaces or quasi-analytic classes. However, it is open whether Sobolev well-posedness without any smallness condition on initial data holds true or not. The aim of my research is to solve this open problem.

Abstract: A foliation on a manifold is typical if the classifying space of its holonomy groupoid is homotopy equivalent to the underlying manifold. D. Calegari showed that there is a codimension-one typical foliation of class at most C^1 on every closed orientable 3-manifold. We construct a smooth (of class C^infinity) codimension-one foliation on every closed orientable 3-manifold.

RECENT RESEARCH ACTIVITIES My research area lies in algebraic geometry. The classical uniformization theorem of Riemann surfaces says that every simply connected Riemann surface is biholomorphic to either the Riemann sphere, the complex plain or the open unit disc. As a higher-dimensional analogue, it is natural to ask the structures of compact Kähler manifolds with holomorphic bisectional curvature having some positivity properties. An algebro-geometric counterpart of this problem is to study smooth projective varieties whose tangent bundle satisfies certain positivity conditions. The story starts with the Frankel conjecture: the only compact Kähler manifold with positive holomorphic bisectional curvature is a projective space. It Research Interests was proved by S. Mori and Y. T. Siu-S. T. Yau independently. In a seminal paper（S. Mori, Projective manifolds with ample tangent bundles, Ann. of Math. (2) 110  Algebraic Geometry (1979), no. 3, 593-606）, S. Mori proved the stronger Hartshorne conjecture: a projective space is the only smooth projective variety whose tangent bundle is ample. As a generalization of the Hartshorne/Frankel conjecture, F. Campana and T. Peternell studied smooth projective varieties with nef tangent bundle. In particular, they classified such varieties in the three dimensional case. After that, J. P. Demailly, T. Peternell and M. Schneider obtained a structure theorem of compact Kähler manifolds with nef tangent bundle. Based on these results, in these years, I have been studying projective varieties Ph.D.,Waseda University from the viewpoint of positivity of tangent bundles. In particular, I am interested in [2010] the following conjecture: The Campana-Peternell Conjecture Any smooth Fano variety with nef tangent Tel.+81-03-3817-1745 bundle is rational homogeneous. E- I obtained various results related to this conjecture. For instance, see the papers mail.watanabe[at]math.chuo- listed in “KEY PUBLICATIONS” below.

RECENT RESEARCH ACTIVITIES The main targets in my studies are shadows and the shadow-complexities of smooth 4-manifolds. The notion of shadows was introduced by Turaev for the purpose of studying quantum invariants of links and 3-manifolds. A shadow is a 2-dimensional polyhedron embedded as a skeleton in a given 4-manifold. It has us define an invariant, called the shadow-complexity, for a 4-manifold. Roughly speaking, it is a non-negative integer measuring how complicated a combinatorial presentation to describe a given 4-manifold must be. Surprisingly, this invariant detects exotic (i.e. homeomorphic but not diffeomorphic) structures on 4-manifolds. We showed that the shadow-complexity of any cork must be greater than 0 Research Interests and that there exist infinitely many mutually non-homeomorphic corks with arbitrary large shadow-complexity. A cork was found by Akbulut as a tool to  Turaevʼs shadows of 3- construct an exotic pair of 4-manifolds. It is known that any exotic pair of and 4-manifolds closed and simply-connected 4-manifolds can be obtained by cork surgery. We  Exotic smooth actually showed that the 4-ball is the only acyclic 4-manifold having the structures on shadow-complexity 0. The above argument holds since the boundary of a cork must have non-trivial mapping class group. To show the existence of infinitely 4-manifolds and corks many corks, we constructed specific examples and computed the hyperbolic volumes and the Casson invariants of their boundaries. As a consequence, we also showed that there are infinitely many exotic pairs of 4-manifolds having Ph.D., Tohoku University arbitrary large shadow-complexity. [2018] We studied a relationship between divides and shadows. A divide was introduced by AʼCampo as a generalization of morsified curves of complex Tel: +81-03-3817-1752 E- plane curve singularities. For a given connected divide, there exists a fibered mail: link, which is the link of a Milnor fibration. We constructed a shadow of a Milnor ball for a connected divide such that a Milnor fiber is embedded in the shadow. The fiberedness of the link can also be checked from this shadow combinatorially. As an application, we gave a sufficient condition to be fibered for the link of a free divide that is a generalization of divides. We also considered a question: if an acyclic 4-dimensional 2-handlebody has the boundary homeomorphic to the 3-shpere, then is it diffeomorphic to the standard 4-ball? If the answer to this question is negative, it concludes that the smooth Poincare conjecture in dimension 4 is false. We gave a sufficient condition for an acyclic 4-dimensional 2-handlebody to be diffeomorphic to the 4-ball in terms of shadows. We also showed that the answer to the above question is affirmative in the case where the connected shadow-complexities are less than 3.

RECENT RESEARCH ACTIVITIES Condensed matter physics using first-principles method is our main research subject. To understand physical properties of matter, it is very important to know electronic structures accurately. First-principles method based on the Density- Functional Theory (DFT) enables us to calculate electronic structures with special account of characteristics of constituent elements. We apply such method to study, for example, cohesion mechanism of quasicrystals [3,5], catalytic properties of intermetallic compounds [4,7], structure of cleaved and adsorbed surface of compounds with complex bulk structure [6], covalent nature in the electronic structures of metals [5], etc. Development of the methods for electronic Research Interests structure calculation is also involved in our activity.

RECENT RESEARCH ACTIVITIES My main research subject is the gauge/gravity correspondence (the AdS/CFT correspondence) and its application to non-equilibrium physics and quark-hadron physics. The gauge/gravity correspondence is a map between a strongly interacting quantum gauge theory and a gravity theory on a higher-dimensional curved spacetime, invented within the framework of superstring theory. For example, some conformal field theory is known to be equivalent to a general relativity on a higher-dimensional anti de Sitter spacetime. Since the gravity theory “knows” the macroscopic physics, such as the entropy and the temperature of the system, in terms of black hole physics, it can be a powerful tool to connect microscopic physics and macroscopic physics. One of my current research subjects is non-equilibrium phase transitions that Research Interests occur only at finite current densities. I and my collaborators are studying their  Superstring theory and properties by using the D-brane dynamics on a curved geometry. I have already gauge/gravity duality discovered novel phase transitions that have not been observed in experiments as  Non-equilibrium steady yet [5]. This is a phase transition between a phase with negative differential conductivity and that with positive differential conductivity. The critical exponents states and non-linear at the critical point have also been defined and computed by using the transport of charge gauge/gravity correspondence [5, 8]. We can also compute the effective  Black holes temperature of the non-equilibrium steady states [7].  Quantum field theory The application of the gauge/gravity correspondence is a new approach to non- equilibrium physics, and I hope we can get new insights into non-equilibrium statistical mechanics in terms of general relativity and superstring theory.

RECENT RESEARCH ACTIVITIES In solid-state materials, various cooperative and dynamic phenomena are known. Photoinduced phase transitions are such phenomena, and they are achieved between different phases and on different timescales. In many cases, electronic orders are melted or weakened. However, in some cases, orders are transiently constructed or enhanced. As a possible mechanism for the enhancement of an electronic order, dynamical localization may work, which suppresses the itinerancy of electrons and enhances the relative importance of interactions during and even after photoexcitation. In some cases, however, it has been shown that dynamical localization is insufficient and electron correlations are necessary to explain experimentally observed details in the enhancement. Research Interests Among the photoinduced phenomena, those that are realized after an intense  Photoinduced Phase light field is applied to solid-state materials have attracted much attention.

RECENT RESEARCH ACTIVITIES We have recently studied the transitions of collective motions of bacterial cells in a shallow circular pool using the bacterial species Bacillus subtilis. The collective motions have been classified into the six phases on a phase diagram with two parameters, the reduced cell length and the cell density . In the recent study, we focused on the sharp transitions at =0.1(≡ c1) with low values of between the random motion phase andλ the one-way rotationalρ motion phase. By introducing the order parameter Q whichλ measuresλ the aligned cell ρmotion along the circumferential direction of a pool, the transitions at = c1 were clearly characterized. Based on the detailed observations of single-cell trajectories in a pool, we verified that the effect of cell-noise interactions wasλ λwidely distributed. We conclude that, even in such random environment, sharp transitions of collective motions were caused by cell-cell interactions a Research Interests  Morphological Diversity in Bacterial Colony Formation on Agar Plates  Transitions of Collective Motions of Bacterial Cells in a Shallow Circular Pool  Size Distribution of Bacterial cells  Fragment-Size Distribution of Long Thin Glass Rods  Morphological Diversity in Crystal Growth of Sodium chloride on Agar Plates

My research interests include superconductivity and magnetism in strongly correlated electron systems. We have developed many home-made measurement apparatuses, such as calorimeter, magnetometer, dilatometer, pressure cell, etc., and performed low-temperature measurements with a precise control of the magnetic-field orientation. In particular, we made a number of important accomplishments in the identification of the gap structures of exotic superconductors. In the case of unconventional pairings, the superconducting gap changes its sign in the momentum space and in most cases the gap has nodes (zeros) in some direction. Because the location of gap nodes is closely related to the underlying pairing interaction, identification of the gap structure becomes one of the most important Research Interests issues in condensed matter physics.  Condensed Matter Physics  Magnetism and superconductivity

RECENT RESEARCH ACTIVITIES In quantum optics, it is of interest to control the state of atoms and molecules. Our group has focused on rubidium atom, which is an alkali-metal and has an electron in the outset. Laser cooling and Bose-Einstein condensate have been achieved by the atoms. Then many researchers have tackled and demonstrated various interesting quantum phenomena. We recently focus on producing the highly angular-momentum state of the atom with laser spectroscopy technique. Figure shows the energy diagram of rubidium atom.

RECENT RESEARCH ACTIVITIES "Geotechnical Engineering" is an engineering discipline that deals with geomaterials (natural soils and rock, potential recycled granular materials) behaviour in an engineering perspective. From a scientific perspective, geotechnical engineering largely involves defining the mechanical properties of geomaterials. Geotechnical knowledge is necessary not only to construct social infrastructure structures such as roads and railways using geomaterials, but also to control disasters related to the ground caused by earthquakes and rainfall. Geotechnical Engineering still has many unknown and unexplained phenomena of geomaterials. Therefore, our laboratory investigates engineering properties of Research Interests geomaterials, stability of soil structures against rainfall and earthquakes, soil improvement and soil reinforcement techniques, from the view of geotechnical  Geotechnical engineering. engineering  Deformation and strength properties of geomaterials  Geosynthetics engineering  Ground improvement

RECENT RESEARCH ACTIVITIES ADRENALINE ADMINISTRATION TO CARDIAC ARREST emergency medical technicians give adrenaline as a vasopressor to cardiac arrest patients. However, its effect has been discussed for half of the century because patients achieve the return of circulation with high probability, which resulted in a low rate of good cerebral function. We focused on the issue of the statistical analysis method. Emergency treatment by professionals is usually performed after a long time from cardiac arrest occurrence. This bias is called as Resuscitation time bias. It is reasonable that continuous cardiac arrest for a long time gets worse than it does for a short time without advanced treatment. Our research addressed the problem and indicated the effectiveness of early adrenaline administration. Research Interests DISPATCHER-ASSISTED CARDIOPULMONARY RESUSCITATION  Pre-hospital emergency In out-of-hospital cardiac arrest cases, chest compression and defibrillation system and treatment performed by bystanders are known as the part of the Chain of Survival, and it plays  Communication issue a great role in increasing resuscitation rate. However, not all bystander can identify cardiac arrest accurately and perform cardiopulmonary resuscitation between emergency (CPR). Dispatchers at the fire department instruct first aid including CPR by caller and dispatcher assuming the situation through the phone call. Our research indicated an association between the recent effort of dispatchers and improvement of cerebral function.

RECENT RESEARCH ACTIVITIES Biological cells, a fundamental unit of life, have astonishing characteristics. They are small and composed of nanoscale non-living materials (DNA, proteins, lipids, etc.), but exhibit various activities. Although cells have various functions alone, they form multicellular bodies by self-organization, and acquire more advanced functions. I am intrigued by these characteristics of life as a physical and mechanical system that spans over multiple scales. To understand the fundamental working principle of biological cells, we try to construct its physical model consisting of purified components, such as DNA, proteins, and lipids. Previously we showed that a pure lipid bilayer membrane can fuse, deform, and divide by simple physical effects. These findings have two major impacts. First, these behaviors of simple models may reflect the way the very early cells, which emerged at the origin of life. Second, they provide design principles of artificial cells that may replace Research Interests the useful functions of biological cells in a  Nanobiotechnology controlled manner.

RECENT RESEARCH ACTIVITIES

Relationship between graph coloring and channel assignment in wireless communication is well-known. For example, the vertex coloring problem of graph theory is applicable to the channel assignment problem of cellular systems (Fig.1), and the edge coloring problem of graph theory is applicable to the channel assignment problem of multi-hop wireless networks (Fig.2). In this study, it is important to find the minimum number of colors (this number is called the chromatic number). To estimate the number of channels in wireless systems, it is also important to find the maximum number of colors (this number is called the Grundy number). In our laboratory, we define new coloring problems applied channel assignment problems and study the properties of the coloring Research Interests problems.  Graph/Network theory and its application.

RECENT RESEARCH ACTIVITIES In our laboratory, we are seeking new approaches to develop materials and devices for energy conversion and for health care etc., by grasping and functionalizing interface, based on knowledge and experimental techniques mainly in the fields of electrochemistry, interface science and material science. The electrochemical reaction, which converts chemical reactions to electricity, and vice versa, is greatly influenced by the fine chemical structure of the interface. For example, some battery fire accidents are considered to be due to the degradation of the interface of electrodes. How to detect such a trigger of degradation at the best timing by non-destructive methods is one of our interests.

RECENT RESEARCH ACTIVITIES Organometallic complexes exhibit rich reactivities as well as interesting structural features depending on the combination of the metal elements and coordinated ligands. By making use of the reactivities of organometallic complexes, even unreactive C-C and C-H bonds can be cleaved under mild conditions. We have been engaged in the investigation of novel transformation reactions of small organic molecules at organo-transition metal complexes. For example, we have successfully developed vinylidene rearrangement of carbon-disubstituted internal alkynes to give the corresponding disubstituted vinylidene complexes (M=C=CRR') via the alkynyl C-C bond cleavage and recombination. Although terminal alkynes have been known to isomerize into vinylidenes at a transition metal center, similar transformation of internal alkynes has been erroneously Research Interests believed to be difficult.

RECENT RESEARCH ACTIVITIES We have developed various spectroscopic and microscopic techniques to study the mechanism of photo-induced processes. Our interests cover photocatalysis, sensitized solar cell, photofunctional liquid crystals and polymers. In any photo-functional devices, there are several key processes which determine the functionality. For example, in the photocatalysis, photo- excited electrons and holes play the key role for the interfacial chemical reactions. In the photo- mobile liquid crystalline polymers, the molecular interaction triggered by the photo-induced molecular change is one of the important processes. To improve the functionality, we need to understand such key dynamic processes, which have been studied with our home-built time- resolved techniques and microscopes. By using the time-resolved techniques, we can measure the dynamic processes with a wide time range from femto (10^(-15)) to second order. In combination with a microscope, not only the temporal response, but also the spatial process can be observed. Based on the fundamental key processes, we could develop various photo- functional devices. Research Interests  Time-resolved spectroscopy  Photocatalysis, Solar cells  Photo-responsive liquid crystal

RECENT RESEARCH ACTIVITIES Marine natural products are an important source of new chemotherapeutics and their lead compounds. However, most of them are not sufficiently available for extensive biological investigations and are reluctant to chemical modifications for analogue synthesis and antibody conjugation. Accordingly, total synthesis plays an important role in the development of new chemotherapeutics based on marine natural products. We have achieved the total synthesis of complex marine macrolide natural products, which are known to show moderate to potent antiproliferative activity against human cancer cell lines. Representative examples include neopeltolide (Angew Chem 2008, 2010), aspergillides A and B (Org Lett 2010), exiguolide (Chem Eur J 2011), lyngbyaloside B (Angew Chem 2015), iriomoteolide-2a (Angew Chem 2018), and enigmazole A (Angew Chem 2018). During these synthetic campaigns, we have Research Interests revised the original stereochemical assignment and established the absolute configuration of lyngbyaloside B and iriomoteolide-2a.

RECENT RESEARCH ACTIVITIES Our main research topics are (1) numerical modelling for the transport phenomena in multiphase flow with the free boundary surface and (2) the chemical process design powered by sustainable and renewable energy. In wet granulation process, a mixture of solid particles and binder liquids, which influence on the interparticle force for particles, is agglomerated or agitated in a granulator. The wettability of a liquid on a solid fundamentally governs characteristics of products as granules or pellets. The interparticle force by the capillary force of a binder liquid has been numerically and experimentally estimated for the complicated mechanism of wet granulation. The developments of numerical simulation method as Lattice Boltzmann Method, Level Set Method or Phase Fields Method are applied for transport phenomena of the liquid deformation with free boundaries. Sustainable or renewable energy powered processes are indispensable for the future prospected systems especially due to the low environmental load. However, the high cost and low effective productivity are the most primal problems to be resolved. A hybridized system is one of the promising technologies for sustainable and renewable processes.

Professor Applied Optimization Laboratory GOTOH, Junya

RECENT RESEARCH ACTIVITIES My primary academic interests have been in applications of mathematical optimization methods with the focus on modeling and algorithms for specially structured optimization problems such as machine learning [4], sparse optimization [3], and financial optimization, and for decision making problems under uncertainty such as robust optimization [1,2]. My methods are mainly based on the so-called continuous optimization. For example, in the practice of data analysis, we often encounter situations where only a designated number of components of a solution vector could be non-zero whereas the rest should be zero. However, this requirement is known to make the associated optimization problems very hard to solve, not only in theory, but also in practice, partly because of the discontinuity of the often-employed function. To tackle this Research Interests difficulty, I and my co-authors [3] have  Operations Research proposed using a reformulation given by a difference of two continuous functions.  Mathematical The above figure shows the shape of the difference function. You might see a cross Optimization at the bottom of the valley of the function. Though this cross is usually represented by a discontinuous function, our proposed method enables us to describe the same  Data Analysis cross by using only a continuous function as above. This has further motivated me  Machine Learning to develop practical algorithms.  Financial Engineering More specifically, the idea of the continuous representation came from my previous study on polytopes Ph.D., Tokyo Institute of [5], which was conducted during my sabbatical period in Technology [2001] 2013. The left-hand side figure shows a polytope which is considered to be the most spherical ones among the so- Tel.: +81-03-3817-1928 called Catalan solids, which is shown in [5]. It may be E-mail: surprising, but a family of the above polytope is used to jgoto [at] indsys.chuo-u.ac.jp construct the function in the first figure.

RECENT RESEARCH ACTIVITIES In conventional information communication theory, the information value is defined from the viewpoint of how accurately the sender can send the content as intended. However, the information value may change depending on the values of the receivers or the situation at that time. We are studying ways to provide valuable information to users according to the context and values of users.

 Decision-making When you go shopping, do you clearly know what you want? Human thinking is ambiguous, and what you want is sometimes unclear. In the case of shopping, we will make decisions while looking at products in shops or talking with shop clerks. We are studying to find ways in which users can clarify concepts and make satisfactory decisions. Research Interests  Human Communication In our life, it is often necessary to solve problems by talking. Rather than  Analyzing and Modeling reasonably deciding by majority vote, it may be better to coordinate the opinions by of Human Thinking discussion.

Assistant Professor Numerical Optimization Laboratory NAKAYAMA, Shummin RECENT RESEARCH ACTIVITIES My research area is numerical methods for solving continuous optimization problems. Specifically, we proposed the memoryless quasi-Newton method for unconstrained optimization problems. The method is one of the quasi-Newton method and relates to the conjugate gradient method. Moreover, we analyzed the properties of the numerical methods. Recently, we have been studying the proximal gradient method which is a numerical method for composite functions. Such problems appear in machine learning. We proposed the proximal gradient method based on the quasi-Newton method. We implement the proposed method to software.

RECENT RESEARCH ACTIVITIES Practical algorithms for cutting and packing problems Cutting and packing problems are representative combinatorial optimization problems with many applications in the wood, glass, steel, and leather industries, as well as in LSI and VLSI design, newspaper paging, and container and truck loading. Almost all cutting and packing problems are known to be NP-hard, and hence heuristics and metaheuristics are important in designing practical algorithms. We proposed efficient construction heuristic algorithms for rectangles, rectilinear blocks, bitmap shapes and three dimensional boxes. Local search and metaheuristic techniques improve the quality of solutions (layouts of small items).

RECENT RESEARCH ACTIVITIES Geometry processing is an active research area that aims at designing algorithms to process 3D shapes efficiently. Main topics in this area include mesh simplification, remeshing, mesh parameterization, mesh segmentation, etc. We're currently focusing on computing curve skeletons of the shape. A curve skeleton is a 1D structure that concisely represents the geometry and topology of 3D shapes. Reeb graphs are one such construct and we develop a parallel algorithm of Reeb graphs on surface meshes.

Research Interests  Geometry Processing  Computational Topology

We also develop an algorithm for modeling interesting wire objects. A dual-view wire sculpture is a wire object that appears in dramatically different shapes when viewed from different viewpoints. The model in the image below can be seen as Ph.D., The University of Rubin's vase. But when we see it from another viewpoint, it looks like a face. In the Tokyo image, we see faces in the mirror.

RECENT RESEARCH ACTIVITIES

Eigenvalue problems are a fundamental problem in numerical linear algebra, and their numerical solution is essential to various areas of computational science and engineering.

Our recent motivation to study eigenvalue problems comes from computational materials science. Of practical interest is a specific subset of eigenvalues and eigenvectors that are closely related to various material properties. We have proposed an efficient algorithm for computing the subset [1], which can help accelerate the development of materials and devices at the nanoscale. Research Interests

RECENT RESEARCH ACTIVITIES It is regarded that nitrogen (N) supply limits global primary production, and N is recycled via biogeochemical N cycle. This means that more crop production can be expected if N is supplied as manure or fertilizer to agricultural field, while excessive N release into water environments may cause deterioration of environment possibly due to massive algal biomass production. N cycle is comprised of a series of microbial redox reactions, which have been applied to wastewater treatment technology. To keep environments productive and unpolluted, microbial activities responsible for N cycle should be properly maintained. Thus, it is quite meaningful to understand how active N cycle is, and I Research Interests and collaborators have worked on this and related subjects as follows.  Improving methods for Improving methods for determining microbial activities responsible for N determining activities cycle.

RECENT RESEARCH ACTIVITIES Actin filaments and microtubules, two essential types of eukaryotic cytoskeleton, determine cell morphology and carry out various cell movements such as cell division and flagella/cilia beating. The protein subunit actin or tubulin undergoes polymerization and depolymerization in a controlled manner, and the polymerized filaments interact with various proteins including motor proteins that produce force for movements. The way cells organize these dynamic processes remains to be studied. An excellent model organism for studying cytoskeleton, especially for studying the formation and function of flagella, is the green alga Chlamydomonas. Previously I isolated a mutant that lacked its primary type of actin and showed that it was viable although displaying reduced flagellar motility due to the lack of a subset of motor proteins. Since that time, our group has been studying various aspects of the cytoskeleton, taking advantage of the powerful Chlamydomonas Research Interests system. Recently, we have succeeded in establishing strains lacking one each of its two α-tubulin and two β-tubulin genes and started large-scale isolation of novel  Molecular Mechanisms tubulin mutants. We are also developing a system for introducing modified actin or of Ciliogenesis tubulin genes into Chlamydomonas.

RECENT RESEARCH ACTIVITIES The earth's surface environment and life which has lived there have undergone irreversible gradual transitions and revolutions. My research interest is extractions of essential turning points for the earth and life and their invariant properties through the geologic time. The recognition of events and organisms which occurred and lived in the geologic time are generally extracted from sediments and fossils. However, Research Interests their information is extremely restricted. The reason is that at first, most of  Paleontology them could not be preserved due to various factors (i.e., erosion, diagenesis,  Sedimentology and degradation). In addition, methods to extract them have been limited. In the case of fossils, researchers have established extraction methods according to physical and/or chemical properties of specific taxonomic groups. On the other hand, fossils which are difficult to be extracted and recognized by existing methods, have been overlooked, even if they were preserved in sediments. Ph.D.,Hokkaido University [2019] I work on extraction of fossils and sedimentary structures, which have not been extracted from sedimentary rocks, using a novel tomography. This method can Tel.+81-03-3817-7193 E- mail.akubota(at)bio.chuo- extract materials regardless of their chemical and/or physical properties. I u.ac.jp particularly focus on the biogenic materials, tissues, and sedimentary structures which has been never recognized. For example, the reconstruction of enigmatic sedimentary structures with abundant fossil fragments by the tomographic method cleared a relationship between sediments and fossil fragments, and this evidence suggested the presence of catastrophic events which has not been recognized. The discoveries of extremely well-preserved fossil concentration (Lagerstätten) has often greatly promoted our recognitions of life. I aim for occurring a new recognition beyond the taxon and chemical/physical properties by full-scanning of the sedimentary rocks.

RECENT RESEARCH ACTIVITIES Nitrification is a key process in a biogeochemical nitrogen cycle and is widely applied to engineered microbial systems. This process proceeds in two steps: ammonia oxidation by ammonia oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB), and nitrite oxidation by nitrite-oxidizing bacteria (NOB). Recently, it was reported that a part of Nitrospira, which were conventionally recognized as NOB, carry out a complete ammonia oxidation (comammox) transforming ammonia to nitrate. This surprising finding reversed our fixed image and challenged us to investigate further.

Traditionally, biochemical and physiological properties of nitrifiers have been characterized based on studies using only representative strains. However, recent

metagenomic analyses and phylogenetic analyses based on the 16S rRNA gene and Research Interests functional genes revealed high diversity and predominance of nitrifiers that have yet to be cultured. Most nitrifiers are fastidious and recalcitrant to cultivate under  Microbial Ecology laboratory conditions. Although isolation and high enrichment are commonly  Environmental performed by classical cultivation methods such as solidified plates and dilution Microbiology techniques, which are easy to handle, the development of new cultivation methods would reveal many hitherto uncultured nitrifiers. Additionally, stable preservation methods of isolated nitrifiers are lacking, with the result that most isolates are not deposited with formal culture collections. Due to the limited available pure cultures, the growth mechanisms of nitrifiers are still unknown. Here, I show my research projects: 1) Development of novel isolation methods for uncultured nitrifiers and Ph.D., Waseda University related microbes, 2) Physiological and genomic characterization of novel nitrifiers, [2013] 3) Exploring interaction between nitrifiers and related microbes.

RECENT RESEARCH ACTIVITIES The Organizer Formation and Gastrulation Movement in Vertebrates Since Spemann and Mangold found the organizer by the transplantation experiment, many scientists have found the organizer genes and molecular mechanism, which are highly conserved among many animals. However, how the organizer is formed during development is unknown. Gastrulation is the earliest dynamic event during vertebrate development following the organizer formation. Although the molecular mechanism of gastrulation is also highly conserved in vertebrates, its movements are thought to be different among the species. To understand the organizer formation and gastrulation movement in Research Interests vertebrates, we proposed a new gastrulation model with African clawed frogs (Xenopus laevis). In our new model, the organizer meets and makes contact with  Experimental prospective neuroectoderm near the equator area where the head is formed, then Developmental Biology elongates body axis posterior-ward. With this model, now we can compare not only  Gastrulation Movement in the amphibian gastrulation but also in vertebrates, such as fish, reptiles, birds,  Organizer Formation and mammals.  Evolution
