Chemical subdomains within the kinetochore domain of isolated CHO mitotic chromosomes. (1991)

We have used indirect immunofluorescence in combination with correlative EM to subdivide the mammalian kinetochore into two domains based on the localization of specific antigens. We demonstrate here that the fibrous corona on the distal face of the kinetochore plate contains tubulin (previously shown by Mitchison, T. J., and M. W. Kirschner. 1985. J. Cell Biol. 101:755-765) and the minus end-directed, ATP-dependent microtubule motor protein, dynein; whereas a 50-kD CREST antigen is located internal to these components in the kinetochore. Tubulin and dynein can be extracted from the kinetochore by 150 mM KI, leaving other, as yet uncharacterized, components of the kinetochore corona intact. Microtubules and tubulin subunits will associate with kinetochores in vitro after extraction with 150 mM KI, suggesting that other functionally significant, corona-associated molecules remain unextracted. Our results suggest that the corona region of the kinetochore contains the machinery for chromosome translocation along microtubules.
Three-phase Inductive Power Transfer System with 12 coils for Radiation Noise Reduction (2018)

A three-phase inductive power transfer system with six transmission coils and six receiving coils is proposed in this paper. The proposed system achieves a reduction in radiation noise by canceling the noise using multiple coils, which are placed opposite to each other. However, in IPT systems with multiple coils, a magnetic interference among the multiple coils decreases a transmission efficiency due to the occurrence of circulating current. The proposed three-phase IPT system achieves cancellation of the interference using six coils on each side. First, the IPT system with the 12 coils is proposed. Then, a canceling condition of the magnetic interference among the coils is mathematically introduced from the voltage equation on the coils. Finally, the proposed IPT system is experimentally demonstrated with the 3-kW prototype. The experimental result shows that the radiation noise at the fundamental frequency is suppressed to 1/6 (from 12.2dBμA to 2.1dBμA).
Diamond, silicon carbide and related wide bandgap semiconductors (1990)

The exact definition of wide bandgap semiconductors versus conventional semiconductors is rather ambiguous. A variety of different semiconductors have been discussed in the present symposium, but the major emphasis, of course dictated by the participant response, has been placed on diamond and silicon carbide. Simply stated, diamond as an emerging material has the greater potential for many of these applications; however, silicon carbide is in a much more advanced stage of development. With the high level of activity in diamond research and development, it may be expected that many of the technological hurdles facing this material will be overcome in the years ahead. On the other hand, if certain key problems cannot be resolved (i.e., a shallow n-type dopant and a heteroepitaxial substrate), or if economic considerations are not favorable, then silicon carbide may be the wide bandgap semiconductor of choice for many of the aforementioned applications. Furthermore, other materials (some discussed in this symposium) will continue to be developed and compete for niches in this fast paced, rapidly growing market.
Generation of sub-10-fs, 5-mJ-optical pulses using a hollow fiber with a pressure gradient (2005)

We propose and demonstrate a pulse compression technique using a hollow fiber with a pressure gradient. This technique improves the spatial and spectral qualities of femtosecond laser pulses spectrally broadened by self-phase modulation, and allows an increase of the pulse energy for pulse compression. Using chirped mirrors for dispersion compensation, we have successfully compressed the pulse to less than 10 fs with an energy as high as 5 mJ.
Studies on the Interspecific Hybridization in Genus Brassica : II. Crossability in Interspecific Cross, B.oleracea L. ×B.campestris L. (1983)

アブラナ属のモノゲノム種間の交雑成功率を高め，より多くの雑種F1植物を得るために，B.oleracea(n=9群)×B.campestris(n=10群)の交雑親和仙1を調査した。B.oleraceaの雌蕊でのB・campestrisの花粉の発芽状況は，花粉芽指数(P.G.I.)でO.7～3.8となり，31組合わせの平均が2，4であった。これは，逆交雑に比べて低く，本交雑における交雑不親和性の1つの要因が，花粉発芽および花粉管伸長過程の異常にあると思われる。雑種胚形成率は，莢当たり0～9.5個でその範囲が広く，平均1.2個であった。雑種胚長は0.4mm前後のものが多く，逆交雑に比べて大型のものが得られた。花粉発芽指数および雑種胚形成率は，交配母本間に差異がみられたが，花粉親閲ではそれが少なく，交雑不親和性は，主に母本の遺伝的特性によるものと考えられる。15℃区では雑種胚形成率が低かったが，20℃区ではそれが高められ，胚の生長も促進された。また，25℃区ではさらに大型の雑種胚が得られた。従って，雑種胚の発育期は，比較的高温下で経過させるのが望ましいと思われる。交配母本の雑種胚形成率と花粉発芽指数および自殖種子稔実率との間には正の相関関係がみられ，交雑親和性の高い母本の選定にあたって，1つの規準になると考えられる。得られた雑種胚を培養することによって，多くの雑種植物が得られ，特に，25℃区で交雑成功率が高かった。これらの雑種植物の後代系統は種・属間交雑による育種の素材として有望であると思われる。

Digitized occlusal reconstruction for dental prostheses (2011)

The aim of this study was to explore a method for automatically reconstructing the occlusal surface by CAD technology. A 3D graphic database of standard tooth crown (STC) was established from physical models. Referring to the contact rule, the occlusal surface of STC was partitioned into several functional regions, and the regions related with occlusal adjustment were further defined as some sets of discrete points. Additionally, geometrical marks were added to the database to embody dimensional contours and orientation of STC. Then an adaptive redesign methodology was developed to form occlusal surface: firstly, a STC similar to patient's anatomical characteristics was scaled and registered to the abutment teeth; secondly, the distances between the point sets and the antagonist were calculated to quantify the occluding relation; finally, the occlusal surface was reconstructed by local deformation. The program provided a novel method to automatically adjust the size and location of the restoration, avoid interpenetrations and create necessary contacts. The final occlusal surface fulfills the esthetic and morphologic criteria in clinical dentistry and meets the physiologic demands of occlusal and proximal contacts.

Silicon Field Emitter Capable of Low Voltage Emission (1993)

A silicon field emitter of a very low voltage emission type has been obtained. In this emitter, a thermal SiO 2 film was used as an insulator which separates the gate electrode from the cathode substrate. It is easy to decrease the distance between the gate electrode and the emitter by thermal oxidation and oblique deposition process. In this field emitter, in spite of 3 µm diameter of initial mask size, we were able to obtain a 400 nm gap which is the distance between the gate electrode and the emitter tip. Therefore, the onset of emission was established at gate voltages as low as 10 V with Fowler-Nordheim-like emission characteristics. Then anode current was 2.5 µA at 25 V in one emitter and transconductance ( g m =ΔIA/ΔVG) was 0.5 µS.
A low sidelobe K&lt;inf&gt;a&lt;/inf&gt;-band antenna-radome study (1975)

An experimental <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">K_{a}</tex> -band (37 GHz) lens antenna designed to have -40 dB sidelobes or lower outside a cone of minimum practical size is described. The results are compared to that optimum Taylor pattern which, for fixed aperture size, maximizes the directivity on boresight subject to the above sidelobe constraint. The effect of a thick homogeneous spherical radome on the sidelobes, as well as a more conventional dish antenna, was also measured.
Measurements of erythemal energy (1949)

With the the growing popularity of solaria and increasing public acceptance of sources generating erythemal ultraviolet, there is a definite need in the field for a rugged, compact direct-reading meter that will measure the E-Vitons per square foot in the same way that a footcandle meter measures lumens/square foot. E-Vitons are the unit to express the health and erythema value of radiations above 2,800 Angstrom units. The design of such a meter is discussed.
Real-time location and parameterization of eyes in an image sequence and the detection of their point-of-gaze (2009)

The determination of point-of-gaze of an imaged subject is the main focus of this thesis. Digitized image sequences from a single camera are analysed to determine the point-of-gaze of a subject without manual setup of algorithms for that subject or calibration of the system. A novel feature of this work is that eyes are initially located by using motion to characterize possible Eye-events. A priori knowledge of an eye's motions, spatial orientation and characteristics are used to find Eye-events. Deformable templates are used to parameterize eyes in an image sequence into a parameterization vector using a 2-D model of the eye and face. The pupil, iris, skin, hair, upper and lower eyelids of a subject are parameterized to form a knowledge base for that subject. The tracking of these eye parameters is performed similarly to their initial parameterization. Point-of-gaze is determined by applying the 2-D eye and face parameters to a 3-D model of the eye. Eye Location, Parameterization, and Tracking algorithms are run using both Matlab on a SPARC 5 workstation and C on a TMS32C40 parallel processing network. The algorithms described in this thesis run equally well on both of these systems. The algorithms are shown to be able to locate eyes in a series of images over a wide range of eye scales. The accuracy of the algorithms is analysed on the SPARC system by having a subject view sets of targets at known locations. The system's determination of a person's point-of-gaze was compared to the actual target positions, showing an error of 4.01° or less along the horizontal axis and 4.99° or less along the vertical axis for targets at or above the eye level of the subject. The accuracy of the system lowers to 5.41° or less along the horizontal axis and 15.76° or less along the vertical axis for targets below the eye level of the test subject. The C40 parallel processing system which runs these algorithms, automatically switching between the Location, Parameterization, and Tracking modes of operation, is described in detail. This system was able to track parameterized eye features at up to 15 frames per second (fps) during saccadic eye motion without a requirement for a fixed head position. The timing of these algorithms on the C40 network is analysed.

Computer control and monitoring of psychrometric conditions. (2000)

This report describes a project undertaken to monitor and control the different air states in an air conditioning plant. From previous equipment purchases and development work, the Department of Mechanical Engineering in Canterbury University has a Hilton® A770 air conditioning rig for demonstrating the basic psychrometric processes, and an environmental control chamber for providing any particular 'outside' air state. In this project a model ‘building’ has been installed inside the environmental chamber to simulate an inside air-state of a building and, has been interconnected to the Hilton rig to supply and condition the air (to the model building) as required. The supplied air state to the model building is controlled by means of the different air conditioning components installed in the Hilton rig such as a preheater, steam generator, refrigerated cooling coil, and a reheater. In turn, the Hilton rig has been modified to use a controlled air state, drawn from the environmental chamber, to simulate winter, summer or any other supply state to the model which is acting as a space load for the Hilton rig. Data acquisition electronics such as sensors, multiplexers and signal conditioners have been installed in the system to manipulate the large amounts of data on real time. Provision of real time display of the values being measured is updated after each sample through a software program written for Windows95®, with a 3-D graphical user interface and other many enhancements. An important feature of this software is that the different air conditioning processes can be displayed on a linked on-screen psychrometric chart developed in the Department of Mechanical Engineering, which can be printed out. Overall, the facility represents, on a much-reduced scale, a building and its air conditioning system operating within an artificially created and controlled outdoor environment. And, using a personal computer, psychrometric conditions are monitored and controlled; the energy transfers are verified; and the different processes are displayed on a psychrometric chart.
Identification of Yin-Yang Regulators and a Phosphorylation Consensus for Male Germ Cell-Associated Kinase (MAK)-Related Kinase (2006)

MAK (male germ cell-associated protein kinase) and MRK/ICK (MAK-related kinase/intestinal cell kinase) are human homologs of Ime2p in Saccharomyces cerevisiae and of Mde3 and Pit1 in Schizosaccharomyces pombe and are similar to human cyclin-dependent kinase 2 (CDK2) and extracellular signal-regulated kinase 2 (ERK2). MAK and MRK require dual phosphorylation in a TDY motif catalyzed by an unidentified human threonine kinase and tyrosine autophosphorylation. Herein, we establish that human CDK-related kinase CCRK (cell cycle-related kinase) is an activating T157 kinase for MRK, whereas active CDK7/cyclin H/MAT1 complexes phosphorylate CDK2 but not MRK. Protein phosphatase 5 (PP5) interacts with MRK in a complex and dephosphorylates MRK at T157 in vitro and in situ. Thus, CCRK and PP5 are yin-yang regulators of T157 phosphorylation. To determine a substrate consensus, we screened a combinatorial peptide library with active MRK. MRK preferentially phosphorylates R-P-X-S/T-P sites, with the preference for arginine at position -3 (P-3) being more stringent than for prolines at P-2 and P+1. Using the consensus, we identified a putative phosphorylation site (RPLT(1080)S) for MRK in human Scythe, an antiapoptotic protein that interacts with MRK. MRK phosphorylates Scythe at T1080 in vitro as determined by site-directed mutagenesis and mass spectrometry, supporting the consensus and suggesting Scythe as a physiological substrate for MRK.
What do we know about cyber risk and cyber risk insurance? (2016)

Purpose This paper aims to provide an overview of the main research topics in the emerging fields of cyber risk and cyber risk insurance. The paper also illustrates future research directions, from both academic and practical points of view. Design/methodology/approach The authors conduct a literature review on cyber risk and cyber risk insurance using a standardized search and identification process that has been used in various academic articles. Based upon this selection process, a database of 209 papers is created. The main research results findings are extracted and organized in seven clusters. Findings The results illustrate the immense difficulties to insure cyber risk, especially due to a lack of data and modelling approaches, the risk of change and incalculable accumulation risks. The authors discuss various ways to overcome these insurability limitations, such as mandatory reporting requirements, pooling of data or public–private partnerships in which the government covers parts of the risk. Originality/value Despite its increasing relevance for businesses at present, research on cyber risk is limited. Many papers can be found in the IT domain, but relatively little research has been done in the business and economics literature. The authors illustrate where research stands currently and outline directions for future research.
A highly compact, wideband GaAs HEMT X-Ku band image-reject receiver MMIC (2002)

A fully integrated MMIC (monolithic microwave integrated circuit) receiver designed and fabricated using the 0.2- mu m pseudomorphic InGaAs-GaAs high-electron-mobility-transistor (HEMT) process technology is discussed. This MMIC receiver incorporates a single-stage RF amplifier, a two-staged balanced local oscillator (LO) amplifier, a single-stage IF amplifier, an IF switch and an image-reject diode mixer. Results from these receiver chips show good conversion gain and image rejection in a single small chip over multioctave frequencies. The chip operates from a single +5 V DC supply and draws 280 mA. Total chip size is 5.5 mm*4.5 mm.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Localized Prostate Cancer Detection with<sup>18</sup>F FACBC PET/CT: Comparison with MR Imaging and Histopathologic Analysis (2013)

(18)F FACBC PET/CT shows higher uptake in intraprostatic tumor foci than in normal prostate tissue; however, (18)F FACBC uptake in tumors is similar to that in BPH nodules. Thus, it is not specific for prostate cancer. Nevertheless, combined (18)F FACBC PET/CT and T2-weighted MR imaging enable more accurate localization of prostate cancer lesions than either modality alone.
Luteal Regression in the Primate: Different Forms of Cell Death During Naturaland Gonadotropin-Releasing Hormone Antagonist or Prostaglandin Analogue-Induced Luteolysis (1999)

Morphological changes in the corpus luteum following natural and induced luteolysis in the marmoset were investigated by light and electron microscopy. Functional corpora lutea were studied in the mid and late luteal phase, naturally regressed corpora lutea in the early and late follicular phase, and corpora lutea induced to regress by administration of GnRH antagonist or prostaglandin F(2alpha) analogue in the midluteal phase. Natural luteolysis was associated with lutein cell atrophy, condensation of cytoplasmic inclusions and organelles, and accumulation of lipid. GnRH antagonist treatment resulted in aggregations of smooth membranes and myelin-like bodies in the cytoplasm of the lutein cells together with complex aggregations of degenerative cells. After prostaglandin treatment, the lutein cells contained numerous small and large vesicles; as the degenerative changes advanced, these vesicles coalesced into alveolar-type vacuoles, and nuclei involuted. These results show that in the marmoset, natural luteolysis and the two luteolytic treatments reveal different forms of luteal degeneration and cell death, none of which fit the ultrastructural criteria for apoptosis. More emphasis needs to be placed on understanding these predominant nonapoptotic forms of cell death in order to elucidate the process of luteolysis in the primate.

Modulation of resistance artery force generation by extracellular Ca2+ (1995)

We tested the hypothesis that increasing extracellular Ca2+ (Cao) over a physiological concentration range depresses vascular smooth muscle force generation by altering the intracellular Ca2+ (Cai)-force relationship. Mesenteric resistance arteries were isolated from Wistar rats; Cai and isometric force were measured using a fura-based method and wire myography. Vessels were depleted of releasable Cai by repeated contraction with norepinephrine; Cao was then cumulatively added back from 0.025-2.5 mM in the presence of an agonist. With norepinephrine, serotonin, prostaglandin F2 alpha, and K+, Cao from 0.025 to 0.8 mM induced a graded increase in Cai and active stress. With the receptor agonists but not K+ raising Cao from 0.8 to 1.6 mM and from 1.6 to 2.5 mM decreased active stress to 82 +/- 6 and 54 +/- 6% of maximum, respectively, P < 0.05. Although there was a transient decrease in Cai in response to both 1.6 and 2.5 mM Cao, steady-state Cai only decreased significantly in response to 2.5 mM Cao (85 +/- 3% of maximum). Inhibition of the sarcoplasmic reticulum Ca(2+)-adenosinetriphosphatase with 1 microM thapsigargin had no effect on the decrease in force induced by high Ca2+. The decrease in active stress induced by 1.6 and 2.5 mM Cao was inhibited by Ca2+ channel antagonists and by blockade of Ca(2+)-activated K+ channels with charybdotoxin (with 1.6 mM Cao, control tension = 67 +/- 10% of maximum vs. charybdotoxin = 99.2 +/- 1%, P < 0.05; n = 9).(ABSTRACT TRUNCATED AT 250 WORDS)
