チタン酸塩を用いた半導体センサの高温における NOx 検知特性 (1995)

A series of metal titanates was examined for their NOx sensing properties at elevated temperatures of 500-600℃. As a result, BaTiO3 and SrTiO3 sensors were found to be rather sensitive to NO and/or NO2 existing in air at 600 and 500℃, respectively, together with practically acceptable response and recovery rates. At these temperatures, both sensors exhibited almost linear sensitivity-NOx concentration correlations in the concentration range of 5-100ppm.The electrical resistance of SrTiO3 sensor at 500℃was almost independent of oxygen concentration in the range of 3-15％and scarcely affected by interfering gases such as CO2, H2, and C3H6. The NOx sensing mechanism of this element was briefly discussed.
The Effect of 5-Fluorouracil Treatment of Chicks: A Cell Depletion Model for the Study of Avian Polymorphonuclear Leukocytes and Natural Host Defenses (1993)

Two-week-old Leghorn chicks injected intravenously with 5-fluorouracil (5-FU) were found to have a three- to fivefold reduction (P < .05) in circulating polymorphonuclear leukocytes (PMN) 5 to 10 days later. The reduction in PMN was dose-dependent with a dosage of 200 mg/kg body weight of 5-FU, causing suppression of PMN to almost undetectable levels. Increasing the dosage of 5-FU to 400 mg/kg had no further effect on reducing the number of PMN in the circulation nor were overt clinical signs of toxicity observed. Single per os administration of 10(6) viable Salmonella enteritidis (SE) to individual groups of chicks treated or not treated with 5-FU at 2, 4, 6, 8, 10, or 12 days postinjection resulted in a two- to sixfold increase in the incidence of SE organ invasion (liver and spleen) beginning on Day 4 postinjection and continuing through Day 12 postinjection. The greatest increase in organ invasion occurred on Days 8 through 10 postinjection and was inversely proportional to the greatest reduction in the number of circulating PMN. Using 5-FU, a granulocytopenic chicken model was developed that can be used to study the defensive role of avian heterophils against infectious agents. The results from these preliminary experiments indicate that PMN play a significant role in reducing organ invasion by SE in Leghorn chicks.
Rapid Detection of Transition Metals in Welding Fumes Using Paper-Based Analytical Devices (2014)

Metals in particulate matter (PM) are considered a driving factor for many pathologies. Despite the hazards associated with particulate metals, personal exposures for at-risk workers are rarely assessed due to the cost and effort associated with monitoring. As a result, routine exposure assessments are performed for only a small fraction of the exposed workforce. The objective of this research was to evaluate a relatively new technology, microfluidic paper-based analytical devices (µPADs), for measuring the metals content in welding fumes. Fumes from three common welding techniques (shielded metal arc, metal inert gas, and tungsten inert gas welding) were sampled in two welding shops. Concentrations of acid-extractable Fe, Cu, Ni, and Cr were measured and independently verified using inductively coupled plasma-optical emission spectroscopy (ICP-OES). Results from the µPAD sensors agreed well with ICP-OES analysis; the two methods gave statistically similar results in >80% of the samples analyzed. Analytical costs for the µPAD technique were ~50 times lower than market-rate costs with ICP-OES. Further, the µPAD method was capable of providing same-day results (as opposed several weeks for ICP laboratory analysis). Results of this work suggest that µPAD sensors are a viable, yet inexpensive alternative to traditional analytic methods for transition metals in welding fume PM. These sensors have potential to enable substantially higher levels of hazard surveillance for a given resource cost, especially in resource-limited environments.
Determination of Evolutionary Relationships of Outbreak-Associated Listeria monocytogenes Strains of Serotypes 1/2a and 1/2b by Whole-Genome Sequencing (2015)

We used whole-genome sequencing to determine evolutionary relationships among 20 outbreak-associated clinical isolates of Listeria monocytogenes serotypes 1/2a and 1/2b. Isolates from 6 of 11 outbreaks fell outside the clonal groups or "epidemic clones" that have been previously associated with outbreaks, suggesting that epidemic potential may be widespread in L. monocytogenes and is not limited to the recognized epidemic clones. Pairwise comparisons between epidemiologically related isolates within clonal complexes showed that genome-level variation differed by 2 orders of magnitude between different comparisons, and the distribution of point mutations (core versus accessory genome) also varied. In addition, genetic divergence between one closely related pair of isolates from a single outbreak was driven primarily by changes in phage regions. The evolutionary analysis showed that the changes could be attributed to horizontal gene transfer; members of the diverse bacterial community found in the production facility could have served as the source of novel genetic material at some point in the production chain. The results raise the question of how to best utilize information contained within the accessory genome in outbreak investigations. The full magnitude and complexity of genetic changes revealed by genome sequencing could not be discerned from traditional subtyping methods, and the results demonstrate the challenges of interpreting genetic variation among isolates recovered from a single outbreak. Epidemiological information remains critical for proper interpretation of nucleotide and structural diversity among isolates recovered during outbreaks and will remain so until we understand more about how various population histories influence genetic variation.
Near-field character of a jet discharged through a wall at 30 deg toa mainstream (1977)

Measurements are reported of the flow created by the injection of a circular jet at 30° through a plane wall, past which an external stream is flowing. Attention has been focused on the region immediately surrounding the injection hole, which has received slight attention in earlier studies. The data include profiles of streamwise velocity and distributions of static pressure and film-cooling effectiveness on the surface, for ratios of average injection velocity: freestream velocity M of 0.1, 0.2, 0.5,1.0, and 1.5. Flow visualization photographs also are presented. Two modes of behavior are observed, according to the magnitude of M. For values of 0.3 and less, the injected jet remains attached to the surface, provoking considerable pressure and velocity disturbances, and giving rise to increasing effectiveness as M is increased. At values of M of 0.5 and above, the jet lifts off the surface, allowing penetration of the mainstream fluid beneath it. As a consequence, the effectiveness now diminishes as M is augmented, as are the surface pressure disturbances, and a complex flow structure is produced. Maximum effectiveness and coverage is observed when M is about 0.5, in conformity with earlier studies.
Considerations for Selection of Techniques for NAT Traversal (2005)

There are many protocols designed and deployed on the Internet today
which do not naturally traverse Network Address Translators (NAT). In
order to allow these protocols to work in the presence of NAT,
additional logic needs to be added to the network. This logic modifies
the behavior of the protocol in some way. There are choices where this
logic can be placed in the network. It can reside in the NATs
themselves, transparently altering the protocol; when this occurs, it
is called an Application Layer Gateway (ALG). It can reside in server
components, hiding the changes from NATs and clients alike, it can
reside in the clients, or it can reside in a combination thereof. The
choice of the placement of this logic typically has implications on
many aspects of the protocol, including security, deployability,
manageability and availability. This document provides a set of
considerations that should be taken into account by protocol and
network designers when making this choice.
Comparative headspace analysis of cabbage plants damaged by two species of Pieris caterpillars: consequences for in‐flight host location by Cotesia parasitoids (1994)

Abstract Headspace composition, collected from intact cabbage plants and cabbage plants infested with either Pieris brassicae L. or P. rapae L. (Lepidoptera: Pieridae) first instar larvae, was determined by GC‐MS. Twenty‐one volatiles were identified in the headspace of intact plants. Twenty‐two volatiles were identified in the headspace of plants infested by P. brassicae larvae, 2 of which, Z‐3‐hexenyl butyrate and Z‐3‐hexenyl isovalerate, were not detected in the headspace of either intact or P. rapae damaged plants. In the headspace of the latter, 21 compounds were identified, all of which were also produced by intact plants. No significant quantitative differences were found between headspace composition of the plants damaged by one or the other caterpillar species. Major differences between intact and caterpillar‐damaged plants in contribution to the headspace profile were revealed for hexyl acetate, Z‐3‐hexenyl acetate, myrcene, sabinene and 1, 8‐cineole. The larval endoparasitoid Cotesia glomerata L. was attracted by the volatiles emanating from B. oleracea damaged by P. brassicae first instar larvae. C. rubecula L., a specialized larval endoparasitoids of P. rapae , was attracted by the volatiles released from the B. oleracea ‐ P. rapae plant‐host complex. This shows that cabbage plants kept under the conditions of headspace collection produce attractive volatiles for both parasitoids.
Integration and evaluation of cache coherence protocols for multiprocessor socs (2006)

System-on-a-chip (SoC) designs is characterized by heavy reuse of IP blocks to satisfy specific computing needs for target applications, reduce overall design cost, and expedite time-to-market. To meet their performance goal and cost constraint, SoC designers integrate multiple, sometimes heterogeneous, processor IPs to perform particular functions. This design approach is called Multiprocessor SoC (MPSoC). In this thesis, I investigated generic methodologies for enabling efficient communication among heterogeneous processors and quantified the efficiency of coherence traffic. Hardware techniques for two main MPSoC architectures were studied: Integration of cache coherence protocols for shared-bus-based MPSoCs and Cache coherence support for non-shared-bus-based MPSoCs. \n\nIn the shared-bus-based MPSoCs, the integration techniques guarantee data consistency among incompatible coherence protocols. An integrated protocol will contain common states from these coherence protocols. A snoop-hit buffer and region-based cache coherence were also proposed to further enhance the coherence performance. For the non-shared-bus-based MPSoCs, bypass and bookkeeping approaches were proposed to maintain coherence in a new cache coherence-enforced memory controller. The simulations based on micro-benchmark and RTOS kernel showed the benefits of my methodologies over a generic software solution.\n\nThis thesis also evaluated and quantified the efficiency of coherence traffic based on a novel emulation platform using FPGA. The proposed technique can completely isolate the intrinsic delay of the coherence traffic to demonstrate the impact of coherence traffic on system performance. Unlike previous evaluation methods, this technique eliminated non-deterministic factors in measurements such as bus arbitration delay and stall in the pipelined bus. The experimental results showed that the cache-to-cache transfer in the Intel server system is less efficient than the main memory access.
Borna Disease Virus Nucleoprotein Interacts with the Cdc2-Cyclin B1 Complex (2003)

Transition from G(2) to M phase, a cell cycle checkpoint, is regulated by the Cdc2-cyclin B1 complex. Here, we report that persistent infection with Borna disease virus (BDV), a noncytolytic RNA virus infecting the central nervous system, results in decelerated proliferation of infected host cells due to a delayed G(2)-to-M transition. Persistent BDV-infected rat fibroblast cells showed reduced proliferation compared to uninfected cells. In pull-down assays we observed an interaction of the viral nucleoprotein with the Cdc2-cyclin B1 complex. Transfection of the viral nucleoprotein but not of the phosphoprotein also results in decelerated proliferation. This phenomenon was found in BDV-susceptible primary rat fibroblast cells and also in primary mouse cells, which are not susceptible to BDV infection. This is the first evidence that the noncytolytic Borna disease virus can manipulate host cell functions via interaction of the viral nucleoprotein with mitotic entry regulators. BDV preferentially infects and persists in nondividing neurons. The present report could give an explanation for this selective choice of host cell by BDV.

Deprotonation mechanism of poly(4-hydroxystyrene) and its derivative (2005)

With the shrinkage of pattern sizes, the elucidation of reaction mechanisms at molecular level has become essential to resist design. Especially, proton dynamics is the most important issue for sensitivity and resolution of chemically amplified resists. Also, nanoscale topography of patterned resist surface such as line edge roughness may be explained by precise proton dynamics. In chemically amplified resists for post-optical lithographies such as EUV and electron beam lithography, it has been reported that protons come not from acid generators but from base polymers. Determining proton sources is a key to understanding reaction mechanisms at molecular level. In this article, we investigated deprotonation mechanism of poly(4-hydroxystyrene) and poly(4-methoxystyrene) on the exposure to ionizing radiation.
V. Confluence of membrane trafficking and motility in epithelial cell models (2002)

Migration of epithelial cells occurs in a variety of important biological processes including tissue morphogenesis, wound healing, and the metastasis of epithelial tumors. In some instances, the cells remain attached to each other and migrate together as a sheet, maintaining epithelial integrity. In others (e.g., metastasis), junctional complexes are disrupted and cells migrate individually. In both cases, motility involves the extension of membranous protrusions (filopodia and lamellipodia) in the direction of movement and the transient assembly and disassembly of integrin-mediated adhesions with the extracellular matrix. The driving force for these events is provided by regulated changes in the organization of the actin cytoskeleton, which are thought to be coordinated with alterations in intracellular membrane traffic. In this themes article, I review current hypotheses about how these processes are integrated and attempt to identify fruitful areas for future research.
Synthesis ofdl-3-Isobutyroxy-β-ionone anddl-Dehydrovomifoliol (1973)

3-Isobutyroxy-β-ionone (III) is the proposed structure of quiesone, the naturally occurring inhibitor of the germination of Peronospora tabacina conidia. This was synthesized as a racemate and shown to possess qualitatively identical biological activity as quiesone itself. Employing an intermediate of this synthesis, dl-dehydrovomifoliol (VII) was also synthesized.
Optical assessment of nonimaging concentrators (2000)

An optical measurement method for nonimaging radiation concentrators is proposed. A Lambertian light source is placed in the exit aperture of the concentrator. Looking into the concentrator's entrance aperture from a remote position, one can photograph the transmission patterns. The patterns show the transmission of radiation through the concentrator with the full resolution of the four-dimensional phase space of geometric optics. By matching ray-tracing simulations to the measurement, one can achieve detailed and accurate information about the geometry of the concentrator. This is a remote, noncontact measurement and can be performed in situ for installed concentrators. Additional information regarding small-scale reflector waviness and surface reflectivity can also be obtained from the same measurement with additional analysis.

An assessment of the performance of a resistivity fish counter (1982)

Closed‐circuit television was used to provide a visual record of the events associated with the counts recorded by a resistivity fish counter. The fish seen were classified as‘ large’fish &gt; 50 cm length and‘ small’fish of &lt; 50 cm. Some of the‘ large‘ fish escaped detection by the counter, some‘ small’fish were counted and some counts were registered when nothing was seen. The sensitivity of the counter varied inversely with water conductivity which varied inversely with discharge. Evidence was obtained suggesting that fish ascending a weir tend to swim closer to the bottom than do those descending. It was found that fish tended to move upstream just after sunset and downstream just before sunrise except when the water was turbid and when the fish were very close to spawning. The numbers of fish movements recorded increased during those periods when discharge was decreasing after a spate but when spawning activity was at its peak, increased activity occurred in the complete absence of any change in discharge. Instances of the same fish re‐crossing the counting zone several times were recorded and the simultaneous passage of more than one fish through the counting zone was observed.
EXPLORING THE RELATIONSHIP BETWEEN LEADERSHIP STYLE AND SAFETY CLIMATE IN A LARGE SCALE DANISH CROSS-SECTIONAL STUDY (2011)

Recent studies provide evidence that high quality management is a determinant for a positive safety climate, but the majority of these studies are predominantly based on small samples from individual industries. The purpose of this paper is to scrutinize the association between transactional and transformational leadership and safety climate, and to explore how safety climate is affected by a number of socio-demographic factors and within different industries and company sizes. The analyses are based on data from a recent Danish work environment cross-sectional study including 3681 employees from a wide range of industries and who report that safety climate is relevant for their job. We use two safety climate items, (one regarding management safety empowerment; one regarding co-workers’ safety priority), one question about transactional leadership and two scales concerning transformational leadership. In addition, we consider the impact of age, gender, education, job type and seniority as well as company size and industrial sector on the rating of safety climate. Predictors of safety climate ratings are analysed by use of multiple regression analysis. Our results show that the leadership style measured by items related to transactional and transformational leadership have a significant positive association with management safety empowerment, whereas workers’ safety priority is only significantly associated with transformational leadership. Younger workers have significantly lower safety climate ratings, and low co-worker safety priority is associated with job type, education and in companies with less than ten employees. These results have important theoretical and practical implications for safety climate interventions and for planning and implementing management strategies that better support employees’ engagement in proactive work environment behaviours.
