[Paper] Free-viewpoint Video Synthesis for Sport Scenes Captured with a Single Moving Camera (2015)

In this paper, we propose an algorithm to realize an immersive free-viewpoint experience, whereby audiences can see real sport scenes from any viewpoint, from a single moving camera. Homography matrix estimation and object extraction are two of the most important processes for synthesizing free-viewpoint video, since a world coordinate position of each object needs to be calculated in every frame based on object textures and homography matrix between captured frame and 2-dimensional world coordinate model of sports coat. Most conventional methods only use static cameras whose homography matrices and background models do not change. However, broadcasters usually utilize moving pan-tilt-zoom cameras in sporting events, and therefore, those methods cannot be directly applied to the events. In order to extend the range of application of free-viewpoint video technology to be used in sport live broadcasting, our proposed method estimates homography matrices semi-automatically by identifying reliable corresponding feature points between video frames, and also extracts the precise textures of objects using estimated homograph matrices. Experimental results revealed that the proposed method successfully estimated the precise homography matrices compared to the conventional method. Moreover, it was also confirmed that the proposed scheme contributes to further improvement in the experience of free-viewpoint video since the textures of multiple objects were successfully extracted.
MBE grown GaInNAs solar cells for multijunction applications (2005)

Triple-junction cells composed of III-V materials currently hold the world record for photovoltaic efficiency. In order to further increase cell efficiency in the future 4- and 5-junction cells incorporating a sub-cell with a bandgap of roughly 1.0 eV will be required. In this study 1.0 eV bandgap GaInNAs devices grown by solid source molecular beam epitaxy are investigated in terms of materials quality and device performance that show similar or better properties to the best MOVPE grown devices found in the literature. Deep-level transient spectroscopy measurements illustrate that the trap concentrations in the GaInNAs material are significantly lower than that of MOVPE grown material. The internal quantum efficiency (43%), open-circuit voltage (450 mV), short-circuit current density (25.76 mA/cm/sup 2/) and fill-factor (56.4%) of the GaInNAs devices under 1-sun power density 1064 nm radiation are similar to or surpass the properties of the best MOVPE GaInNAs devices found in the literature.

The initial effects of Alzheimer's disease on cognitive function are more pervasive than just episodic memory failure.
Switchable Ethylene Tri-/Tetramerization with High Activity: Subtle Effect Presented by Backbone-Substituent of Carbon-Bridged Diphosphine Ligands (2013)

The effect of backbone-substituent of carbon-bridged diphosphine ligands of the types {Ph2PCH(R)CH2PPh2} and {Ph2PC(R)═CHPPh2} on the catalyst performance in ethylene oligomerization has been explored. Cr complex bearing a methyl-substituted diphosphine ligand with saturated linker exhibited the highest selectivity of 64.7% toward 1-octene. Cr complex bearing a tert-butyl-substituted diphosphine ligand with unsaturated linker showed a high activity of 4238 kg/(g Cr/h) at 40 bar and 40 °C and achieved a high total selectivity of 79.1% toward valuable 1-hexene and 1-octene. The 1-hexene selectivity could be improved up to 55.2% (19.4% 1-octene) at 20 bar and 80 °C. Some of the new complexes are even more active than the well-known most efficient ethylene tri/tetramerization catalyst systems.
Polysilicon diodes as temperature sensors for chemical microreaction systems (2002)

Lateral polysilicon P/sup +/-N-N/sup +/ and P/sup +/-P-N/sup +/ diodes were fabricated and their electrical properties such as ON current, reverse current and series resistance were studied at various temperatures in the range of 50/spl deg/C to 150/spl deg/C. It was found that both reverse and forward currents of the diodes increased with the temperature. Using these electrical properties as parameters, the lateral polysilicon diodes can be used as temperature sensors in microreaction systems.
An Integrated TV Video Modulation System (1977)

New developments in T. V. add-on areas such as V. D. R., games, and data display, have produced a common need for composite video encoding and R. F. modulation circuits to interface with the T. V. receiver. This paper reviews the basic reqiurements for this area and then presents a new T. V. video modulation system using only one integrated circuit.* The new system includes the sound subcarrier oscillator and chroma subcarrier encoding circuits, in addition to R. F. oscillators and modulators for two low-V.H.F. channels. Channel switching is achieved with a d,c.-operated switch.
Variation in cellular EGF receptor mRNA expression demonstrated by<i>in situ</i>reverse transcriptase polymerase chain reaction (1993)

Cell to cell variation of epidermal growth factor (EGF) receptor mRNA levels in heterogeneous tissues has been demonstrated with an in situ assay that couples reverse transcriptase with the polymerase chain reaction (in situ RT-PCR). EGF receptor mRNA is consistently more highly expressed in regions where cell division occurs; EGF receptor mRNA is markedly reduced if not absent in areas of squamous cell differentiation. Both human and mouse tumors overexpress EGF receptor mRNA when compared to normal tissue. In situ RT-PCR performed on thin sections obtained from cell pellets of cultured cells with known levels of EGF receptor mRNA expression demonstrated that the mRNA detected is consistent with that observed by Northern analysis and quantitative PCR on isolated RNA and by protein levels detected by antibody binding assays. In situ RT-PCR is significantly more sensitive than in situ hybridization (ISH). The method avoids background associated with hybridization reactions as in ISH or ISH following in situ PCR. In situ RT-PCR appears to be applicable to any gene as long as the oligonucleotide primers used have been proven to be specific and effective in a standard RT-PCR assay.
Particles emission control at graphite cathode in arc ion plating deposition (1997)

In this work, the dependence of the vacuum arc spot velocity on physical and electrical properties of different graphite cathode materials is investigated in the presence of a variable magnetic field. A pulsed arc system is used to perform preliminary experiments on the arc mobility for the different types of graphite for the selection of proper material morphology and the design of a continuous vacuum arc system. The characteristics of arc mobility, erosion rate, and carbon ion flux emitted from the continuous carbon source are then evaluated in view of particle-free diamond-like protective coatings. Results show that the arc spot velocity on graphite cathodes is larger on cathodes having larger grain size, lower electrical resistivity and higher apparent density. The spot velocity is also lower for cathodes having larger pore sizes and total porosity. The arc spot velocity is also found to be increased by increasing the magnetic field intensity over the surface of any graphite type. Reduced residence time of the spot on a given site of the cathode resulting from arc velocity increase should lead to a reduction in the heat load input in the cathode spot. This correlates with results on the number of emitted particles, the film thickness and roughness, and the erosion rate that are found to decrease, while the ion flux emission is increased. Diamond-like carbon (DLC) films free of particles are produced in a continuous arc ion plating (AIP) system. The ion energy in the continuous AIP system is found to vary with the graphite surface properties and the intensity of a plasma confining magnetic field in front of the cathode. The ion energies measured vary between 39.8 eV to 62.6 eV.
Discrimination Analysis of Blood Plasma Associated with Alzheimer's Disease Using Vibrational Spectroscopy (2013)

In this study we have determined whether Raman and infrared spectroscopy of blood plasma differentiates Alzheimer's disease (AD) from normal aging of healthy controls. Spectroscopic analysis was conducted on blood plasma samples from 8 mild AD, 16 moderate AD, 11 severe AD, and 12 normal elderly control persons using Fourier transform spectrometers and a near-infrared laser beam as excitation source for Raman spectroscopy. Spectra were processed employing discriminant analysis to determine whether band areas and frequency-intensity relationships might reveal biochemical differences associated with AD. Seven spectral biomarkers were identified in the Raman regions of 1700-1600 cm-1 (protein secondary structure), 980-910 cm-1 (protein α-helices), 790-730 cm-1 (protein tertiary structure), and 440-390 cm-1 (protein backbone) and in the infrared regions of 1700-1600 cm-1 (protein secondary structure) and 1150-1000 cm-1 (oxidative stress). This discriminant analysis model differentiated AD from normal aging of elderly control persons with a sensitivity of 89% and specificity of 92%. Moreover, specificity increases to 100% for the detection of mild AD. In summary, our results open the possibility of using this spectroscopic approach as a non-invasive, rapid, and relatively inexpensive procedure for early accurate diagnosis of AD.
Electrochemical treatment and reuse of nickel plating rinse waters (2002)

Abstract The treatment and disposal of nickel‐contaminated rinse waters places an additional cost‐burden on a metal plating facility. Increasing the resource productivity within an electrolytic nickel plating process by creating a recycle loop for the “waste” components of the rinse water can reduce disposal and raw material costs. In this study, an electrowinning cell, fitted with an anion exchange membrane, was used to recover valuable components from a simulated electrolytic nickel plating rinse water by a combination of electrodeposition and electrodialysis. The anion exchange membrane in the cell permitted a dual electrode function. Nickel metal was recovered from the rinse water at the cathode and a sulfuric/hydrochloric acid mixture was generated at the anode (which can be used in the pickling baths to clean metal parts). The boric acid in the rinse water could not be recovered by anion exchange due to its high acid dissociation constant. The cell worked effectively in both a batch and a continuous feed mode. The research demonstrated that this type of electrochemical cell could feasibly replace the traditional ion exchange process for treating rinse waters, and eliminate regeneration chemicals/waste while producing useful process materials.
Measurement of the metabolic products of nitric oxide in hemodialysis patients. (1996)

一酸化窒素 (NO) は近年最も注目を集めている物質の一つであるが, 血液透析患者での報告は極めて少ない.NOは生体内においてほぼ完全に亜硝酸イオンおよび硝酸イオン (NO2-/NO3-, NOx) に代謝されるので, 今回, 維持透析患者30例と保存期腎不全患者20例および健常者19例において血漿中NOx濃度を測定し, さらに維持透析患者群においては血圧および大動脈石灰沈着との関係についても比較検討した. 血漿中Nox濃度は維持透析患者群 (透析前) で平均171.0±96.65×10-6M, 保存期腎不全患者群で136.0±68.76×10-6Mと, 両群とも健常者での平均値 (59.3±31.42×10-6M) に比べ有意に上昇しており, さらに維持透析患者中, 高血圧群および重度石灰沈着群において有意な高値を示した.今回の検討より, 維持透析患者ではNOx産生亢進が広範囲にわたってみられ, さらにマクロ的血管病変にNOが深く関わっていることが強く示唆された.
Rotihibins, Novel Plant Growth Regulators from Streptomyces graminofaciens. (1995)

In the course of screening search for plant growth regulators, a culture filtrate of Streptomyces graminofaciens 3C02 was found to inhibit the growth of lettuce seedlings. The active substances, named rotihibin A (1) and B (2), were revealed to be lipo-peptidal compounds. Rotihibins inhibit growth of various plants at below 1 microgram/ml, but do not show lethal activity even at higher doses.
10 bit 200 MS/s CMOS D/A converter employing high-speed limiter (2002)

A 10 bit 200 MS/s CMOS current-steering digital-to-analogue converter (DAC) employing a new voltage limiter to reduce the feedthrough of the control signals is presented. For high-speed operation of the limiter, a design technique based on the parasitic capacitor of a PMOS transistor is proposed. At 200 MS/s, a spurious-free dynamic range of 65 dBc for a 40 MHz output signal has been achieved from the proposed DAC.

Purification and lipid-layer crystallization of yeast RNA polymerase II. (1990)

Yeast RNA polymerase II was purified to homogeneity by a rapid procedure involving immunoaffinity chromatography. The purified enzyme contained 10 subunits, as reported for conventional preparations, but with no detectable proteolysis of the largest subunit. In assays of initiation of transcription at the yeast CYC1 promoter, the enzyme complemented the deficiency of an extract from a strain that produces a temperature-sensitive polymerase II. Mammalian RNA polymerase II was inactive in this initiation assay. The purified yeast enzyme formed two-dimensional crystals on positively charged lipid layers, as previously found for Escherichia coli RNA polymerase holoenzyme. Image analysis of electron micrographs of crystals in negative stain, which diffracted to about 30-A resolution, showed protein densities of dimensions consistent with those of single polymerase molecules.
The Discovery and Process Development of a Commercial Route to the Water Soluble Prodrug, Fosfluconazole (2001)

A case history detailing the rationale behind the discovery of 2-(2,4-difluorophenyl)-1,3-bis(1H-1,2,4-triazole-1-yl)-2-propyl dihydrogen phosphate, fosfluconazole (2), a water-soluble prodrug of Diflucan, and the subsequent development of a commercial route is presented. Particular items to note are (i) that this compound was discovered in the Chemical Research and Development Department, hence Chemical Research and Development can play a key role in prodrug discovery, (ii) the strategy behind the selection of phosphate ester promoiety, by phosphorylation of a sterically hindered tertiary alcohol, (iii) the development of the initial route to remove thermally hazardous reagents and to improve processing to allow scale-up, and (iv) the identification and development of the proposed commercial process.
The effect of flux diverters on AC losses of a 10 kVA high temperature superconducting demonstrator transformer (2001)

In this paper the design, construction and characterization of a 50 Hz single phase high temperature superconducting (HTS) transformer is presented. The transformer is designed to deliver 10 kVA at 77.4 K and 20 kVA at 65 K. The transformer is made of two windings positioned at the middle limb of a three-limb iron core. The secondary winding is made of nine double pancake superconducting coils, using silver sheathed BPSCCO-2223 multifilamentary tapes with nominal critical current of 20 A (at 77.4 K and self field). The primary winding is made of copper to reduce the cost of HTS material. Utilizing a superinsulated nonmetallic doughnut shaped cryostat with low background heat leak, the AC losses in the superconducting winding have been measured by calorimetric method. Two powdered iron flux diverters have been used inside the cryostat at both ends of the superconducting winding in order to reduce the radial component of leakage flux density in the HTS tapes. The use of these flux diverters is shown to be very effective in reducing the AC losses by 40% at the nominal current.
Antibacterial Phenylpropanoid Glycosides from Paulownia tomentosa (Thunb.) Steud. Var. tomentosa Fruit (2007)

Column chromatographic study on the aqueous acetone (70%) extract of Paulownia tomentosa (Thunb.) Steud. var. tomentosa fruit led to the isolation of 4 phenylpropanoid glycosides and their structures were determined as verbascoside (1), isoverbascoside (2) campneoside Ⅱ (3) and isocampneoside Ⅱ (4) by chemical and spectral analyses. Compounds 1-2 were isolated from the title plant for the first time. The study on antibacterial activity showed that the isolated compounds, acetone extract, EtOAc and H2O fractions exhibited significant inhibition, particularly against Staphylococcus epidermidis.
Discharge patterns of human C-fibers induced by itching and burning stimuli (1991)

1. The aim of this investigation was to study the peripheral neural mechanisms of the C-fiber-mediated modalities of burning pain and itch by the use of microneurography of human unmyelinated afferents. 2. Sixteen stable recordings of single C-fibers and 6 multiunit recordings were obtained from the superficial radial nerves of volunteers. All units were excited by stimulating their receptive fields with von Frey bristles (range 10-600 mN), and all but four units were also driven by radiant heat stimulation. 3. Histamine was iontophoretically applied to the receptive fields of these units for 20 or 30 s and was found to provoke itching sensations lasting several minutes, together with wheal and flare responses. Subsequently a solution containing 20 or 30% mustard oil was applied to the receptive field of the respective unit, which provoked a sensation of burning pain. 4. One-half of the units were excited by histamine, and the median discharge rates derived from interspike intervals ranged from approximately 0.1 to 0.8 Hz. Mustard oil-induced activity was observed in all histamine-sensitive units and also in three single units and in one multiunit recording that revealed no histamine response. Median interval-derived discharge rates ranged from 0.2 to 1.2 Hz. 5. Analysis of the interspike interval distribution and of the autocorrelation function derived from the chemically induced discharges of single units provided no evidence for an encoding of itch and burning pain in different discharge patterns of units responding to histamine and to mustard oil.(ABSTRACT TRUNCATED AT 250 WORDS)
Microwave imaging for brain tumour detection using an UWB Vivaldi Antenna array (2012)

An Ultra wide-Band (UWB) Vivaldi Antenna array is used for microwave imaging based brain cancer detection. A cancerous brain model which consists of a 5 mm tumour and four layers is simulated with CST Microwave Studio. The input pulse is radiated into brain model and the pulse response is recorded by the receiver antenna. The analytical signal function has been employed to eliminate the noise and the scanning method is applied for microwave imaging. The image processing result shows a good agreement with the actual tumour location in the brain model.
Teaching physiology through simulation of hemodynamics (2002)

A user-friendly interface to a mathematical model for teaching cardiovascular physiology is developed. The underlying model, a lumped-parameter approximation of cardiovascular hemodynamics and control, 'comes to life' in this real-time simulation. Students interact with the model through the X Window System interface, using the mouse to create continuously updating, realistic graphs of blood pressure, volume, or flow for any of the compartments. Students perform experiments on a 'virtual patient' in order to understand the intrinsic properties of the system as it responds dynamically to normal stresses and pathological insults. Instructors may set up patient cases with simulated diseases and ask students to examine the hemodynamics in order to make a diagnosis. Using this program, students are able to explore the function of the cardiovascular system in greater depth than would be possible through conventional teaching methods.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Raman Investigation of Surface OH-Species in Porous Silica (2003)

Surface in porous media has a key role for both theoretical and technological aspects. A comparative analysis of the surface vibrational properties of sol−gel synthesized porous silica monoliths with different porosity is presented. Raman spectroscopy investigation of the fundamental O−H stretching range (3000−3800 cm-1) reveals a dependence of the surface reactivity on pore dimensions. The pore surface curvature plays an important role affecting the hydrogen-bonding interaction between surface hydroxyls and modifying the distribution of the OH species at the surface; the relative contribution of interacting hydroxyls and adsorbed water with respect to isolated species is larger in smaller pores. Water and silanol vibrations were singled out as a function of porosity.
Immunogenicity. I. Use of Peptide Libraries to Identify Epitopes That Activate Clonotypic CD4+ T Cells and Induce T Cell Responses to Native Peptide Ligands (1999)

Recent studies have demonstrated the utility of synthetic combinatorial libraries for the rapid identification of peptide ligands that stimulate clonotypic populations of T cells. Here we screen a decapeptide combinatorial library arranged in a positional scanning format with two different clonotypic populations of CD4+ T cells to identify peptide epitopes that stimulate proliferative responses by these T cells in vitro. An extensive collection of mimic peptide sequences was synthesized and used to explore the fine specificity of TCR/peptide/MHC interactions. We also demonstrate that many of these deduced ligands are not only effective immunogens in vivo, but are capable of inducing T cell responses to the original native ligands used to generate the clones. These results have significant implications for considerations of T cell specificity and the design of peptide vaccines for infectious disease and cancer using clinically relevant T cell clones of unknown specificity.
High-efficiency (7.2%) flexible dye-sensitized solar cells with Ti-metal substrate for nanocrystalline-TiO<sub>2</sub>photoanode (2006)

High-efficiency flexible dye-sensitized solar cells were fabricated with a Ti-metal foil substrate for photo anode and using a Pt-electrodeposited counter electrode on ITO/polyethylene naphthalate (ITO/PEN); these devices were characterized by incident photon-to-current efficiency (IPCE), optical transmittance and electrical impedance spectroscopy.
Ellagic acid glycosides from<b><i>Turpinia ternata</i></b> (2006)

Bioassay-guided fractionation of the methanolic extract of Turpinia ternata stems, has led to the isolation of the new ellagic acid derivative 3,4'-di-O-methylellagic acid-4-O-alpha-L-arabinofuranoside (1), and the known compounds ellagic acid (2), 3-O-methyl ellagic acid (3), 3-O-methylellagic acid-3'-O-alpha-L-rhamnopyranoside (4), and 3,3'-di-O-methylellagic acid-4'-O-alpha-D-glucopyranoside (5). Their structures were elucidated by extensive spectroscopic methods. Compounds 1, 3, and 4 showed moderate antioxidant activity against DPPH free radical, whereas compound 1 was found to be moderately cytotoxic against Artemia salina larvae.
