A Natural Framework for Chaotic Inflation (2009)

We show that inflation with a quadratic potential occurs naturally in theories where an axionlike field mixes with a 4-form. Such an axion is massive, with the mass which arises from the mixing being protected by the axion shift symmetry. The 4-form backgrounds break this symmetry spontaneously and comprise a minilandscape, where their fluxes can change by emission of membranes. Inflation can begin when the 4-form dominates the energy density. Eventually, this energy is reduced by membrane emission, and the axion can roll slowly towards its minimum, as in the simplest version of chaotic inflation.
Interfacial Shear Rheology of Aged and Heat-Treated β-Lactoglobulin Films:  Displacement by Nonionic Surfactant (2000)

Interfacial shear rheology of adsorbed beta-lactoglobulin films (bulk protein concentration 10(-)(3) wt %) has been studied over the temperature range 20-90 degrees C using a two-dimensional Couette-type viscometer. Effects of the type of interface (air-water, triolein-water, and n-dodecane-water), the pH (2.0, 5.6, 6.0, 7.0, and 9.0), and the extent of the heat treatment have been assessed via measurements of changes in the apparent interfacial shear viscosity and elasticity before and after the addition of increasing amounts of nonionic surfactant Tween 20 (polyoxyethylene sorbitan monolaurate). The highest interfacial viscosities were obtained at the n-dodecane-water interface and the lowest at the air-water interface. Competitive displacement of protein from the interface by Tween 20 was easier at the air-water and n-dodecane-water interfaces as compared to the triolein-water interface. The surface shear viscosity was higher and the displacement by Tween 20 more difficult as the isoelectric point of the protein was approached, which is in agreement with the presence of a more strongly cross-linked protein network at the interface. The effect of heat treatment was dependent on the pH of the aqueous solution. No simple relationship between the surface rheological characteristics and the ease of displacement by Tween 20 could be inferred.
Oxidative stress plays a major role in chlorpromazine-induced cholestasis in human HepaRG cells (2012)

These data provide evidence that, among other mechanisms, oxidative stress plays a major role as both a primary causal and an aggravating factor in the early CPZ-induced intrahepatic cholestasis in human hepatocytes.
The First Extrasolar Planet Discovered with a New‐Generation High‐Throughput Doppler Instrument (2006)

We report the detection of the first extrasolar planet, ET-1 (HD 102195b), using the Exoplanet Tracker (ET), a new-generation Doppler instrument. The planet orbits HD 102195, a young star with solar metallicity that may be part of the local association. The planet imparts radial velocity variability to the star with a semiamplitude of 63.4 ± 2.0 m s^-1 and a period of 4.11 days. The planetary minimum mass (m sin i) is 0.488MJ ± 0.015M_J. The planet was initially detected in the spring of 2005 with the Kitt Peak National Observatory (KPNO) 0.9 m coudé feed telescope. The detection was confirmed by radial velocity observations with the ET at the KPNO 2.1 m telescope and also at the 9 m Hobby-Eberly Telescope (HET) with its High Resolution Spectrograph. This planetary discovery with a 0.9 m telescope around a V = 8.05 magnitude star was made possible by the high throughput of the instrument: 49% measured from the fiber output to the detector. The ET's interferometer-based approach is an effective method for planet detection. In addition, the ET concept is adaptable to multiple-object Doppler observations or very high precision observations with a cross-dispersed echelle spectrograph to separate stellar fringes over a broad wavelength band. In addition to spectroscopic observations of HD 102195, we obtained brightness measurements with one of the automated photometric telescopes at Fairborn Observatory. Those observations reveal that HD 102195 is a spotted variable star with an amplitude of ~0.015 mag and a 12.3 ± 0.3 day period. This is consistent with spectroscopically observed Ca II H and K emission levels and line-broadening measurements but inconsistent with rotational modulation of surface activity as the cause of the radial velocity variability. Our photometric observations rule out transits of the planetary companion.
Attenuation compensation in distributed amplifier design (1989)

A high-gain common-gate FET that presents at its drain a broadband impedance characterized by a (frequency-dependent) negative resistance and a capacitance is examined theoretically and experimentally. Loading the input and/or the output lines of a distributed amplifier with this circuit reduces the signal losses, leading to an increase in the allowed number of active devices with a consequent increase in the gain-bandwidth and gain-maximum-frequency products. The cascode circuit, a related loss reduction network, is also evaluated because of its use in distributed amplifiers. Several designs employing the common-gate FET loss-compensating circuit and/or the cascode amplifying circuit are compared to a conventional distributed amplifier optimized for gain-bandwidth product. Simulated gain-maximum-operating frequency product increases of 27% to 245% over that of the optimized conventional distributed amplifier are shown. The increase in single-stage amplifier gain provided by this technique often results in (proportionally) higher maximum output power.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Fe<sub>3</sub>O<sub>4</sub>/Sb–SnO<sub>2</sub> Granules Loaded on Ti/Sb–SnO<sub>2</sub> Electrode Shell by Magnetic Force: Good Recyclability and High Electro-oxidation Performance (2015)

Guided by the ideas of green chemistry and green engineering, a new developed electrode with interchangeable coatings was fabricated for electrochemical oxidation (EO). This electrode consists of a permanent magnet NdFeB, a Ti/Sb–SnO2 electrode shell and a number of magnetic Fe3O4/Sb–SnO2 granules. The granules are fixed on the electrode shell by magnetic attraction force. Necessary characterizations were used to reveal the morphology, composition and magnetic property of the magnetic granules. The electrochemical properties of the new electrode were investigated by the cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The performance of the new electrode and its stability in the EO process were carried out. Finally, the recyclability of the granules was also tested. Results show that the new electrode has a larger real surface area than the conventional electrode (two-dimensional electrode). The real current density on the new electrode is decreased, which results in a higher EO ability and higher electrode stability. The energy is also saved because the cell voltage is decreased. In addition, the magnetic granules could still be attracted and recycled after a long time use. This new electrode could be considered as a renewable electrode, and the lifetime of the EO system could be increased by a factor of 5 when granules are renewed timely.

Visual-Inertial Odometry Tightly Coupled with Wheel Encoder Adopting Robust Initialization and Online Extrinsic Calibration (2019)

Combining camera, IMU and wheel encoder is a wise choice for car positioning because of the low cost and complementarity of the sensors. We propose a novel extended visual-inertial odometry algorithm tightly fusing data from the above three sensors. Firstly we propose an IMU-odometer pre-integration approach utilizing complete IMU measurements and wheel encoder readings, to make scale estimation more accurate in subsequent 4-degrees of freedom (DoF) optimization. Secondly we develop an original initialization module where encoder readings are fully utilized to refine gravity direction and provide an initial value for camera pose in real scale. Thirdly, we design a computationally efficient online extrinsic calibration method by fixing the linearization point for the rotational component of IMU-odometer extrinsic parameters, which is deployed depending on the convergence of accelerometer bias. Experimental results prove the robustness of our initialization module and the accuracy of the whole trajectory, as well as the improvement brought about by online extrinsic calibration. Our program can also run on an Nvidia Jetson TX2 module in real time.
Direct Fourier Tomographic Reconstruction Image-To-Image Filter (2007)

We present an open-source ITK implementation of a direct Fourier method for tomographic reconstruction, applicable to parallel-beam x-ray images. Direct Fourier reconstruction makes use of the central-slice theorem to build a polar 2D Fourier space from the 1D transformed projections of the scanned object, that is resampled into a Cartesian grid. Inverse 2D Fourier transform eventually yields the reconstructed image. Additionally, we provide a complex wrapper to the BSplineInterpolateImageFunction to overcome ITK’s current lack for image interpolators dealing with complex data types. A sample application is presented and extensively illustrated on the Shepp-Logan head phantom. We show that appropriate input zeropadding and 2D-DFT oversampling rates together with radial cubic b-spline interpolation improve 2D-DFT interpolation quality and are efficient remedies to reduce reconstruction artifacts.
연구논문 / Rotifer , Brachionus plicatilis , 성장을 위한 광합성세균의 첨가 효과와 넙치 , Paralichthys olivaceus , 자에 대한 먹이효율 (2000)

Rotifer의 대량배양에는 해산 chlorella가 가장 적합하나 비용이 높고, 유지효모는 경제적인 긴 하나 먹이효율이 낮은 문제점이 있다. 이와 같은 문제점을 개선하기 위하여 본 연구에서는 광합성세균 (Rhodopseudomonas capsulata)의 첨가 효과를 조사 하였다. Rotifer한 개체당1일 먹이량으로 10,000, 50,000, 100,000, 200,000, 300,000세포의 Chlorella ellipsoidea를 공급하고 각 chlorella 수의 10, 20, 30배의 광합성세균을 첨가한 결과 200,000세포에 광합성 세균 20배 (4×10^6 cell)를 공급한 것이 가장 성장이 높았으나 경제적인 측면에서는 chlorella 100,000세포에 광합성세균 30배를 공급하는 것이 더 효과적이었다. 또, rotifer 1개체당1일 먹이량으로 유지효모를 100,000, 200,000, 300,000세포를 공급하고 각 유지효모수의 10, 20, 30배의 광합성세균을 첨가한 결과 200,000세포에 광합성세균 20배를 첨가한 실험구에서 rotifer의 성장이 가장 높았다.
Chlorella와 유지효모를 각각 200,000 세포씩 그리고 chlorella와 유지효모에 광합성세균을 20배의 농도로 첨가하여 rotifer를 배양하여 넙치 자어를 사육한 결과 chlorella에 광합성세균을 첨가한 실험구의 생존율이 96.8%로 가장 높았으며 성장의 경우도 광합성 세균을 첨가한 실험구에서 높은 경향을 보였다. 또 광합성세균을 첨가한 실험구에서의 넙치 자어는 총지질과 EPA와DHA의 함량이 광합성세균을 첨가하지 않은 실헙구에서보다 높게 나타났다. Artemia nauplius를 6시간동안 광합성세균으로 영양강화하여 넙치 치어를 20일간 사육한 결과 영양강화한 것은 하지 않은 것보다 생존율과 성장이 높았으며 광합성세균의 최적영양강화농도는 ㎖당 2×10^7 cells로 나타났다. Chlorella와 유지효모에 광합성세균의 첨가는 rotifer의 성장과 자치어의 생존율과 성장에 효과적이었다. 그러나 과다한 양의 광합성세균은 오히려 negative effect가 있는 것으로 나타났다.
Heat capacity of LiInS<sub>2</sub>, LiInSe<sub>2</sub> and LiInTe<sub>2</sub> between 200 and 550 K (1987)

Abstract The molar heat capacity at constant pressure of LiInS 2 , LiInSe 2 and LiInTe 2 was measured in the temperature range from about 200 K to 550 K. An analysis of the experimental data showed that the anharmonic contribution to the heat capacity can be described by a polynomial of fourth order in the temperature. A comparison of the results for the LiInC 2 VI compounds with those for the AgB III C 2 VI and A II B IV C 2 V chalcopyrite compounds showed that the lattice anharmonicity effects are essentially influenced by the specific nature of the LiC VI bond.

Digital rights management for visual content in mobile applications (2004)

With the emergence of wide bandwidth wireless networks, mobile Internet is set to provide a significant channel of multimedia content distribution. In the absence of proper digital rights management (DRM) systems, there is a real risk for content owners and producers to lose important revenues due to their intellectual property rights. To avoid market fragmentation and ensure interoperability, the Open Mobile Alliance (OMA) has set to define open DRM specification in their standardization process. In this paper, we review the specified methods of DRM within OMA. We present a scheme that utilizes watermarking as complementary solution for DRM on mobile devices, and we discuss how it could enhance the security of copyrighted media distribution. We focus the attention on the application of DRM methods for visual content in mobile devices.
Application of virtual microscopy in clinical cytopathology (2001)

Abstract Virtual microscopy (VM) refers to the use of an automated microscope and digital imaging technology to scan, store, and view glass slides. VM systems allow the user to view a scanned image of the entire slide at multiple magnifications on a computer screen. We tested VM to evaluate its possible utility in diagnostic cytopathology. Ten cervical‐vaginal monolayered preparations (AutoCyte™ preparation) were scanned using a BLISS™ (Bacus Laboratories Inc. Slide Scanner) system. Approximately 20–30% of the cellular area of each slide was imaged. The cases were randomly chosen to include examples ranging from benign cellular changes (BCC) to high‐grade squamous intraepithelial lesions (HSIL). The computer performed image tiling and fusing of multiple JPEG images to create a high‐quality VM slide. Six examiners (two each of cytopathologists, senior residents, and cytotechnologists) blindly evaluated the VM slides using an image server program (WebSlide Browser™ thin client software). The cytopathologic diagnoses made on the VM slide were then compared to the original glass slide diagnoses. BLISS™ took 36–100 min (avg. 58.4 min) to scan the selected fields in a glass slide with file sizes ranging from 23.1–83.6 MB. Time taken by the examiners to render a diagnosis ranged from 1–15 min (avg. 4.1 min) per case. The combined diagnostic accuracy was 98.3%. Only one case of LSIL was missed by one examiner. VM is a promising new tool, which gives a user the feel and simulated experience of an actual microscopic examination and provides a useful alternative to a glass slide in diagnostic cytopathology. Possible applications include: 1) second opinion consultation without transporting the glass slide, 2) education, 3) VM proficiency tests / board exams, and 4) telepathology. Shortcomings include 1) expensive initial setup, 2) inability to maintain an adequate focus in a thick smear with multiple levels, 3) large storage size of the VM slide, and 4) relatively long time needed to scan a slide.

Novel BST:MgTiO 3 Composites for Frequency Agile Applications (2002)

The (Ba 1 m x Sr x )TiO 3 (BST) system is well known for its high response of the dielectric constant to an applied electric field. However, the large dielectric constants found in this system limit its usefulness at microwave frequencies. A number of groups have used composite structures to dilute the dielectric constant and suppress the dielectric loss of BST for microwave applications. Typically, the low dielectric constant material MgO has been used as the secondary phase in the composites. In this work, we report on the dielectric properties of BST composites using the microwave dielectric MgTiO 3 . Room temperature dielectric constants of <400 (measured at 1 kHz), and dielectric tunabilities of ∼36% (at 20 kV/cm) have been achieved for the BST:MT composites. Due to the superior quality of these composite ceramics, large electrical breakdown fields in excess of 100 kV/cm are possible. High-field measurements indicate that the dielectric tunability of BST:MgTiO 3 composites can be as high as 70% at 80 kV/cm.
The Production and Characterisation of a Panel of Ten Murine Monoclonal Antibodies to Human Procoagulant Factor VIII (1986)

A panel of 10 murine monoclonal antibodies to procoagulant FVIII has been developed from the fusion of a single spleen. Balb/c mice were injected with a purified preparation of FVIII: Ag, and antibody production in sera and hybrid culture supernatants was monitored using a specific radiometric screening assay. The antibodies all inhibit FVIII clotting activity in normal plasma, and when immobilised on agarose retain their ability to recognise and bind the FVIII procoagulant protein. Studies on protein A-purified immunoglobulins demonstrate a range of properties within the panel of antibodies with regard to species cross-reactivity, clotting inhibition and immunoadsorption. The panel of antibodies has been used to screen heat-treated FVIII concentrates for the occurrence of heat-induced neoantigens.

Classification of groundwater samples in wetlands using self- organizing maps (2006)

Groundwater chemistry in groundwater-fed wetlands often is the result of mixing of discharging groundwater and rainfall in combination with chemical reactions altering the chemical composition, mostly due to changes in redox conditions. In this study, a Self-Organizing Map is used to classify chemical groundwater samples of three groundwaterfed wetlands in Belgium in order to identify the origin of groundwater and to deduce redox conditions in the wetlands. The Self-Organizing Map (SOM) algorithm is an unsupervised neural network technique to represent a multidimensional dataset on a two-dimensional grid in a topology-preserving way, allowing investigation of non-linear, complex relationships between variables and grouping of the data (Kohonen, 1995). The SOM is trained with data from a regional groundwater monitoring network and rainfall data. The resulting SOM is able to distinguish between samples of different origin or redox conditions within the regional aquifers. Subsequently, samples of the three wetlands are shown to the SOM and each sample is classified as having a chemical composition comparable to rainfall or to one of the regional aquifers.
