The coastal wave height is dominated by the persistent easterly winds induced by the developed Okhotsk high. These winds, which can induce cool summers in northern Japan, favor wave development toward the coast of northern Japan. The wave variability is enhanced along the coast of northern Tohoku by the strong local winds occurring in the lee of Cape Erimo. The results for variability of wave height along the Pacific and Okhotsk Sea coasts of northern Japan are supported by composite analysis of reanalysis wave data. When the Okhotsk high develops and the resulting easterly winds are dominant, the wave height increases near the coast of and to the east of northern Japan. Wave height also increases in the Japan Sea and along the southern coast of Japan, whereas wave height decreases in the Okhotsk Sea. These wave height variations reflect the distinct wind fields associated with the developed Okhotsk high. Trends in wave height are examined using the in situ measurements available for over 20 yr. Only the decreasing trends in the south of northern Japan in August are statistically significant.

This process leads to substantial density increase in SiO2-rich rocks and, in turn, to a reduction of the buoyancy of the subducted material, which should inhibit exhumation. Nevertheless, coesite- and diamond-bearing continental crustal rocks are known from several occurrences worldwide. We report on the discovery of microdiamond in kyanite-garnet gneiss from allochthonous metasediments of the Seve Nappe Complex in the Scandinavian Caledonides. Our discovery calls for general reconsideration of existing exhumation models of deeply subducted continental crust. We propose that the diamond-bearing rocks were subducted in an arc-continent collision setting, and their exhumation was facilitated by local pressure reduction resulting from extraction of the forearc lithospheric block.

The Method for Motivation by Quality Function Deployment (QFD)

Abstract This paper presented a study on proposing a method for motivation with the use of QFD. It was reported by three students who majored in MOT at Graduate School of Science and Engineering, Yamagata University in 2009. QFD has been widely used in manufacture and service industries for making improvement with the existing products and programs. However, in this study, QFD was not used in the sense of “activation” to improve motivation. Rather, it took the viewpoint of “what is required by customers”, the central theme QFD, to approach the problem. With reference to the process of knowledge conversion suggested by the SECI Model, the study operated with the basic principles and steps of QFD. In the paper, the major steps of QFD leading to setting quality planning were outlined and the implication of the study was discussed.

Some natural fault zones contain carbonaceous material (CM) even where host rocks do not contain it, and seismic fault motion can promote the graphitization of low-grade CM. Thus, the origin of CM in fault zones is an important issue in fault mechanics. Previous high-velocity friction experiments have revealed various chemical reactions in fault zones during seismic fault motion, but most experiments have been conducted in an atmosphere under oxic conditions. Here we report experimental results on Carrara marble (free of CM), conducted under N2 or H2 atmospheres at a slip rate of 1.3 m/s and normal stresses of 2.0–3.1 MPa. A small amount of blackish material formed in generated gouge only under reducing conditions with the H2 atmosphere, and Raman spectroscopic analysis revealed the presence of CM (amorphous carbon) in the material. The CM is attributable to (1) the generation and pyrolitic dissociation of CH4, and/or (2) a reduction reaction of emitted CO2 due to calcite decomposition. We confirmed the formation of CH4 using gas chromatography. The CM produced in experiments resembles CM in the Nojima fault (Japan) gouge in terms of Raman spectra. The granitic host rock of this fault is free of CM, and calcite is precipitated close to the CM; therefore, the CM probably formed through processes similar to those simulated in our experiments. Future research should investigate the amount and origin of CM in natural fault zones.

Foreword

Foreword Donald G. Davis Jr. (bio) My generation, born before World War II, grew up during the era of the cold war, roughly between 1945 and 1990. It was a peculiar time, when the Soviet Union and its satellites were pitted against the United States and its allies. Measured against the times, before and since, when national borders were more open and freedom of thought and movement prevailed generally, this period will always hold special memories for those who lived through it. As one who during these years was educated and entered his chosen career—library historian and bibliographer in professional education—this was an unusually interesting period. Most people only read about the East–West struggle in Europe, and comparatively few from the North Atlantic community traveled much in Eastern Europe, including the Soviet Union. In the fall of 1975, along with my wife, Avis, I attended the Library History Seminar VI in Chapel Hill, North Carolina. After we had picked up Paul Kaegbein, a distinguished and indefatigable German library historian, at the airport, we shared dinner with him at a restaurant that featured Central and Eastern Europe cuisine. A native of Estonia who was caught up in the war and the Soviet hegemony of Eastern Europe in its aftermath, Kaegbein was passionate about maintaining somewhat risky collegial relationships with our professional colleagues in the Eastern bloc. They often could not travel, he said, but we in the West could. That dinner talk was the beginning of my interest in embracing my mentor’s passion for crossing the Iron Curtain for the sake of library connections. Subsequent trips to Poland and the Soviet Union cemented this interest. My enthusiasm was rewarded when Hermina Anghelescu, guest editor of this two-part issue, came from the Romanian National Library to study in the Graduate School of Library and Information Science at the University of Texas at Austin in the 1990s. She stayed on to complete her doctorate [End Page 107] with a magisterial dissertation on the history of libraries in modern Romania. Hermina may have left Romania, but her heart was always with her colleagues at home. Thus, she organized four short summer seminars for Romanian public and academic librarians in the late 1990s, for which she enlisted American friends as faculty. I accompanied the team on three of these ventures and witnessed for myself how librarians were developing new attitudes and charting new courses in a society free of former constraints. While the communist mentality had boosted literacy on a wider scale, librarians were now eager to provide new resources and services. Later, the 2004 IFLA Conference in Berlin brought the post–World War II period into clearer vision for me as my family and I stayed in a beautiful apartment in what was once East Berlin. We roamed all over the reunited city at will, enjoying its beauty and treasures. True, we have had surveys of libraries during the cold war. Now it is time to assess the status of Eastern European libraries in the twenty-five years that have followed since its demise. The commissioning, collecting, and editing of the extensive essays that follow in this comprehensive survey could only have been accomplished by the guest editor who possesses extraordinary gifts of imagination, networking, persistence, and completion. This collection will provide a new benchmark in the history of libraries in Eastern Europe. While all the news may not be good, we can be grateful for this summary review. [End Page 108] Donald G.

Interview

Prof. Takashi Tokuda of the Graduate School of Materials Science at the Nara Institute of Science and Technology (NAIST) in Japan, talks to us about the work behind the paper ‘CMOS sensor-based palm-sized in-line optical analysis device for microchemistry systems’, page 1222. Prof. Takashi Tokuda I have been developing CMOS-based novel sensors for new applications in bioscience, chemistry, and medicine with Prof. Jun Ohta here at NAIST. In this particular case, we had an idea to realise polarisation detection using a monolithically embedded wire grid polariser, made with a metal layer, in standard CMOS processes. We can realise polarisation imaging without any post-fabrication process or external optics. After we demonstrated the basic functionality of the embedded polariser [reported in Electronics Letters, Vol. 45, issue 4], we knew that Prof. Kiyomi Kakiuchi, who majors in synthetic organic chemistry here, had a demand for a small-sized, in-line polarimeter to monitor his microchemistry system. We then started a collaboration which has led us to the present work. Microchemistry systems include various chemical reaction/analysing systems that take advantage of narrow channel or small-volume reactors. They include the concept of micro total analysis systems (µ-TAS). We think our CMOS sensors with polarisation detection (and other functionality) can be a good solution for in-situ monitoring in microchemistry systems. We can integrate various sensing functionalities, including light detection for absorption measurement, polarisation detection for chirality monitoring and other electric and electrochemical sensing on a small sensor. As a future work, we have an idea for direct integration of the CMOS multifunctional sensor into various microchemistry systems. In the paper, we developed a palm-sized in-line optical analysis device. We demonstrated its functionality to simultaneously measure polarisation rotation and absorption of a chemical solution. The device is equipped with our polarisation-analysing CMOS image sensor. We realised a volume of the in-line optical analysis device as small as 1/1000 of a typical desktop polarimeter. The in-line optical analysing device presented in this paper does not have any mechanical rotating optics. Furthermore, we integrated a capability of single-wavelength absorption measurement. These features originate in the functional flexibility of our polarization-analysing CMOS image sensor. From the viewpoint of CMOS image sensor technology, the embedded polariser within CMOS process is a good strategy for polarisation detection especially in more advanced processes, thus we expect more work in this will appear in the future. The integration of the CMOS-based small and multifunctional sensor is another interesting and promising topic. Although it is in a stage of proof-of-concept, it is expected to be a powerful monitoring solution for high-performance microchemistry systems in the future. This work was performed in projects supported by a grant-in-aid from the Japan Society for the Promotion of Science. It is also a part of our research activity to pursue new CMOS-based intelligent sensors. Our research interests cover not only optical detection, but also various multifunctional sensing schemes. We are also working on CMOS-based neural sensing/interfacing technologies. We are developing various sensors and other devices using the surface of CMOS chips as novel functional surfaces. We think that our approach to use the CMOS electronics more directly for biological, chemical and medical applications could become one of the next trends of the research field. We expect more researchers to join this field and many CMOS-based unique sensors/functional devices will be proposed and demonstrated. We hope a new industrial market will be born from this field.

Introduction

Introduction Ellen Cunningham-Kruppa (bio) As is the case with many worthy projects, the seeds of this festschrift to David B. Gracy II began humbly—in the hallway of an office suite. Five years ago David announced that his retirement from the University of Texas at Austin (UT Austin) School of Information would go into effect at the end of the spring 2011 academic semester. Janelle Dupont, then managing editor of Libraries & the Cultural Record, worked in the office next to me. (David’s office was on the other side of Janelle’s.) Janelle, ever one to be thinking ahead, asked me what I thought about the two of us coediting a festschrift for David. It was a fine and fitting idea; David’s career has evinced innumerable critical contributions to advancing the archives field in the United States. My personal admiration and affection for David extend back to 1985, when I was his student at UT Austin. He is my mentor, colleague, and friend. Far too early in her life, Janelle died in 2010. In 2011 I began working on the festschrift as guest editor. The contents of this issue are the result of a very rewarding two-year period commissioning papers and working with scholars who have known David and witnessed his extraordinary hard work in developing the archives field in the United States as professional practice and academic discipline. The papers address five themes that characterize David’s career and scholarly interests: education of archivists; advocacy for archives; archival description; intersections of libraries, archives, and museums; and local records. Following the order of these topics, Patricia Galloway discusses the development of a discourse about and cadre for archival education in the United States, counterpointed by developments at UT Austin from the perspective of Gracy’s career. Randall C. Jimerson [End Page 1] examines the impact of Gracy’s Archives and Society initiative while he served as SAA president and its importance for and impact on some of the current themes being discussed in the profession today, such as archives and justice, advocacy and accountability, and the role of archivists in society. Reviewing the historical background and discourse surrounding early descriptive developments at the US National Archives from 1935 to 1941, Anne Gilliland identifies three discursive strands and discusses their implications for archivists today. Deanna Marcum suggests that while libraries, archives, and museums have taken separate paths to professionalization, the digital environment, along with its many opportunities for collaboration, is now bringing these cultural institutions closer together. Finally, describing efforts to preserve local records, Martha Doty Freeman enumerates the ways in which their uses have intensified since the mid-twentieth century. Researchers who wish to study David Gracy’s career further can consult the biographical references noted in his curriculum vitae, published in this issue. Also, an essay-length biography of David Gracy written by Kimberly Anderson can be found archived in the UT Austin School of Information’s digital archival repository at https://pacer.ischool.utexas.edu under “School of Information Faculty” and “David B. Gracy II.” I wish to thank all of the authors for their excellent contributions to this festschrift. It has been my honor and pleasure to work with and learn from each of you. I especially wish to thank my colleague Patricia Galloway, professor in the UT Austin School of Information. As always, she has been a wonderful collaborator, helping to define the subjects the festschrift would address and offering sage editorial advice. Finally, a special thanks to the memory of Janelle Dupont, whose sharp mind and personal warmth touched the lives of the faculty, staff, and students who worked with her.

Estimation method for biophysical properties of insect neurons in the combination of suitable stimulation and multi-compartment simulation with supercomputers

Event Abstract Back to Event Estimation method for biophysical properties of insect neurons in the combination of suitable stimulation and multi-compartment simulation with supercomputers Daisuke Miyamoto1*, Tomoki Kazawa2, Stephan Haupt2, Masashi Tabuchi3, Tomoaki Mori1, Kei Nakatani4 and Ryohei Kanzaki2 1 Graduate School of Information Science and Technology, The University of Tokyo , Japan 2 Research Center for Advanced Science and Technology, The University of Tokyo , Japan 3 Graduate School of Engineering, The University of Tokyo , Japan 4 Graduate School of Life and Environmental Science, Tsukuba University , Japan The importance of local dendritic activicty in information processing of single neurons has been generally recognized. Constructing multi-compartment simulation models that also reflect the distribution of active conductances in real neurons is the one of the big challenges to achieve realistic modeling due to the paucity of experimental data. As a remedy to this problem, we propose an estimation method combining suitable electrical stimulation and massively parallel computation using genetic algorithms. We applied this method to projection neurons in antennal lobes of silkmoth (Bombyx mori) as the first model neurons. We obtained morphological tree models containing about 4,000 cylindrical compartments from confocal microscopy images. We assumed the presence of known insect K+, Na+ and Ca2+ channels and used candidate distribution models to estimate the corresponding conductances. Several types of electrical stimuli (current ramps, optionally with added sine waves of different frequencies, and voltage clamp pulses) stimuli, were evaluated for their efficiency in providing multi-compartment models reproducing the electrophysiological data. Such estimation methods need to run multi-compartment simulations many times. To meet the computational demands of the method, we used the Real Coded Genetics Algorithm (RCGA) for parallel efficiency and MPI/OpenMP hybrid implementations on the K computer which has 640,000 SPARC64VIIIfx CPU cores and on the RIKEN Integrated Cluster of Clusters (RICC).For estimating the position of a high-conductance area in an axon, injecting a current ramp with added sine wave showed good performance even after a small number of generations of the genetic algorithm (Fig. 1). This could be related to the frequency transmission characteristics of the axon. With 32,768 genes and 200 generations per estimation, we achieved parallel efficiency as high as p=0.99987 comparing the 1,024 cores and 8,192 cores cases (Fig. 2). We showed here that 1) RCGA is suitable for estimating biophysical properties for realistic multi-compartment models with high efficiency in massively parallel computation and that 2) suitable choice of stimulation paradigms can improve the efficiency of estimation. The interaction between experimental data simulation and parameter estimation can be a useful tool to improve multi-compartment models.

Acute anterior uveitis after discontinuation of tocilizumab in a patient with rheumatoid arthritis

BackgroundTocilizumab is a humanized monoclonal anti-interleukin-6 (IL-6) receptor antibody and has been approved in Japan for the treatment of Castleman’s disease, rheumatoid arthritis (RA), and systemic juvenile idiopathic arthritis. Conjunctivitis and dry eye are known ocular adverse effects, but uveitis has not been reported.Case reportA 72-year-old woman had undergone bilateral cataract surgery without complications. Six months after the surgery, she was diagnosed with RA and treated with tocilizumab infusion every 4 weeks. However, severe malaise and dizziness occurred after the third tocilizumab infusion, and the treatment was suspended. Since the symptoms associated with RA had resolved, she was followed without any medication thereafter. At 5 weeks after the third tocilizumab infusion, she developed severe anterior inflammation with hypopyon in her left eye, and her visual acuity dropped to less than 2/200. Considering her age and history of cataract surgery, endophthalmitis was suspected and a vitrectomy was performed, but no pathogens were detected from the intraocular fluid samples collected during surgery. The ocular inflammation was gradually resolved with systemic antibiotics and corticosteroids. However, severe anterior uveitis recurred in the same eye during the tapering of the systemic corticosteroids, when the aqueous humor IL-6 level was 46,100 pg/mL. The recurrent ocular inflammation was resolved with increased doses of topical and systemic corticosteroids, and the patient has since remained relapse-free. No symptom of inflammation was observed in the right eye during the follow-up period.ConclusionThis case indicates a possibility that acute anterior uveitis may have been an adverse effect after the discontinuation of anti-IL-6 receptor antibody therapy in a patient with RA.
