Model-based car tracking integrated with a road-follower (2002)

This paper discusses how we integrated our 3D car tracking approach with the lane following module RALPH on the Navlab autonomous vehicles, obtaining a hybrid vision system that tracks both the road and cars better than those two systems in isolation. The tracking system brings precise and crisp measurements of the car in the image, and performs image stabilization. However, because it does not know, about the yaw or lateral offset of the ego-vehicle, its curvature estimate can be misguided. RALPH takes a more global image processing approach and can provide this missing information, as well as a good estimate of curvature, so that the combined curvature estimate is superior to both taken in isolation. The additional information provided by RALPH also improves tracking performance, and allows us to estimate properties of the tracked car that were previously unobservable, in particular its in-lane displacement. Better car tracking, and a better idea of where the road is, gives us a substantial foundation on which to base other capabilities needed to realize fully autonomous vehicles.
Characteristics of a Coupled Cell‐Free Transcription and Translation System Directed by Vaccinia Cores (1978)

A coupled transcription and translation system is described in which protein synthesis is directed by mRNA synthesised in situ by vaccinia virus cores. The cell‐free system is based on a micrococcal‐nuclease‐treated reticulocyte lysate. The polypeptides made in vitro include many authentic early vaccinia proteins, but also other proteins which were not detected in infected cells. Concentrations of cores which inhibit host cell protein synthesis in vivo caused a delayed inhibition of translation in vitro ; this was partly, but not entirely, due to dsRNA associated with the cores. The mRNA made was methylated by core enzymes. Inhibition of methylation reduced the rate of translation tenfold; unmethylated RNA bound ribosomes poorly, but was nevertheless translated faithfully.
Magnetic properties of new ternary R6Ga3Fe11 compounds (1990)

Three new rare earth–iron ternary compounds with the La6Ga3Co11 structure (I4/mcm), Pr6Ga3Fe11, Nd6Ga3Fe11, and Sm6Ga3Fe11, are found to be ferromagnetic with Curie temperatures of 320, 397, and 462 K, respectively. Large anisotropies have been observed from the magnetization curves and the anisotropy field is larger than 7 T at room temperature. First-order magnetization processes were observed for all samples throughout the temperature range of 4.2–300 K. Point charge calculations give A20=1070 K a−20 at the 16l site and −283 K a−20 at the 8f site.
Fabrication of self-lubricating cobalt coatings on metal surfaces (2007)

Composite coatings of Co + fullerene-like WS2 nanoparticles on stainless steel substrate were obtained through electroless deposition, using DMAB (dimethyl borane complex, 97%) as the reducing agent, and by electroplating in acidic solution. Phase analysis results show that the coatings consist of Co and the fullerene-like WS2 nanoparticles alone. Tribological measurements show reduced wear and friction of the composite coatings as compared with the pure cobalt film or the stainless steel substrate.

Review of the fundamentals of thin-film growth (2002)

The properties of a thin film of a given material depend on the film's real structure. The real structure is defined as the link between a thin film's deposition parameters and its properties. To facilitate engineering the properties of a thin film by manipulating its real structure, thin-film formation is reviewed as a process starting with nucleation followed by coalescence and subsequent thickness growth, all stages of which can be influenced by deposition parameters. The focus in this review is on dielectric and metallic films and their optical properties. In contrast to optoelectronics all these film growth possibilities for the engineering of novel optical films with extraordinary properties are just beginning to be used.
An Ultraviolet-activated K+ Channel Mediates Apoptosis Of Myeloblastic Leukemia Cells (1999)

Exposure of mammalian cells to UV light causes initial changes in the cell membrane, induces phosphorylation and clustering of growth factor/cytokine receptors, and activates the Jun N-terminal kinase/stress-activated protein kinase (JNK/SAPK) signaling pathway leading to programmed cell death (apoptosis). In this study, we found that an early event in the cell membrane of myeloblastic leukemia (ML-1) cells was the vigorous activation of the voltage-gated K+ channel by UV irradiation. The strong enhancement by UV irradiation of K+ channel activity in the cell membrane subsequently activated the JNK/SAPK signaling pathway and resulted in myeloblastic leukemia cell apoptosis. Suppression of UV-induced K+ channel activation with specific channel blockers prevented UV-induced apoptosis through inhibition of UV-induced activation of the proteins SEK (SPAK kinase) and JNK. However, suppression of K+ channel activity could not protect cells from etoposide-induced apoptosis, which bypasses the membrane event. Elimination of extracellular Ca2+ had no effect on the UV-induced and K+ channel-mediated JNK/SAPK activation. Thus, we have identified a novel mechanism in which activation of K+ channels by UV-irradiation upstream of SEK and SAPK/JNK mediates UV-induced myeloblastic cell apoptosis.
The study of fabrication of the x-ray mirror by numerically controlled plasma chemical vaporization machining: Development of the machine for the x-ray mirror fabrication (2000)

A numerically controlled plasma chemical vaporization machining (CVM) machine has been developed in order to fabricate ultrahigh accuracy x-ray mirror efficiently without making the deformed layer. In this machine, a gas bearing was applied to both of the rotary electrode for plasma generation and an XY table in order to maintain the cleanliness of the machining atmosphere. A silicon flat mirror for the x-ray was made by using developed machine. A value of 22.5 nm (p–v) was achieved as flatness. The CVM technique is more fully described in the accompanying article in this issue.
A textbook example: the academic library and Cengage Learning eTextbook pilot (2016)

This paper shares both publisher and library perspectives and findings from a 2014/2015 Cengage-Learning eTextbook pilot project, an Australia and New Zealand first for institutional elending and region-specific eTextbooks for the academic library. In mid-2014, seven eTextbooks were released via established aggregator platform, EBL, with a three-concurrent-user model. An additional twenty titles were added for first semester 2015. Preliminary results are presented in this paper. The benefits of integrating and experiencing eTexts in new Teaching and Learning paradigms has yet to be fully realised across stakeholders, posing both risk and opportunity for both library and publisher.
Increased expression of receptor activator of NF-<i>κ</i>B ligand (RANKL), its receptor RANK and its decoy receptor osteoprotegerin in the colon of Crohn's disease patients (2004)

Crohn's disease (CD) is associated with low bone mass due to chronic inflammation and other factors. Receptor activator of NF-kappaB ligand (RANKL), its receptor RANK and its decoy receptor osteoprotegerin (OPG) are potentially involved in this process as they regulate osteoclastogenesis and are influenced by pro-inflammatory cytokines. The aim of this study was to determine the levels of soluble RANKL (sRANKL), RANK and OPG expression both in the serum and in the colon of CD patients. Levels of sRANKL and OPG were assessed in the serum and the supernatants of cultured colonic biopsies in patients with CD and controls by ELISA. RANK expression was explored by immunostaining and immunofluorescence of fixed colonic samples. OPG and sRANKL levels were higher in the serum of CD patients as compared to age- and sex-matched controls. Levels of sRANKL and OPG were significantly enhanced in cultured colonic biopsies from CD, and OPG levels correlated with histological inflammation, and pro- and anti-inflammatory cytokine levels. No significant correlation was found for sRANKL. RANK+ cells were increased in the colon of CD, particularly in inflamed areas. These cells were positive for CD68 or S100 protein. We conclude that serum and local levels of sRANKL and OPG are increased in CD. Moreover, RANK is expressed in the colonic mucosa by subpopulations of activated macrophages or dendritic cells at higher levels in CD compared to normal colon.

Thermal gating of the single molecule conductance of alkanedithiols (2005)

The temperature dependence of the single molecule conductance (SMC) of alpha,omega-alkanedithiols has been investigated using a scanning tunnelling microscopy (STM) method. This is based on trapping molecules between a gold STM tip and a gold substrate and measuring directly the current across the molecule under different applied potentials. A pronounced temperature dependence of the conductance, which scales logarithmically with T(1), is observed in the temperature range between 293 and 353 K. It is proposed the origin of this dependence is the change in distribution between molecular conformers rather than changes in either the conduction mechanism or the electronic structure of molecule. For alkanedithiols the time averaged conformer distribution shifts to less elongated conformers at higher temperatures thus giving rise to higher conductance across the molecular bridges. This is analysed by first calculating energy differences between different conformers and then calculating their partition distribution. A simple tunnelling model is then used to calculate the temperature dependent conductance based on the conformer distribution. These findings demonstrate that charge transport through single organic molecules at ambient temperatures is a subtle and highly dynamic process that cannot be described by analysing only one molecular conformation corresponding to the lowest energy geometry of the molecule.
House of quality improvement by new design requirements generation (2015)

Integration voice of customer into new product development (NPD) process is an important factor that creates more customer satisfaction. Quality function deployment (QFD) is widely used to capture customer requirements (CRs) which are real by focusing on customers' needs. It helps organizations to translate CRs to the major design requirements (DRs) in such a way that they can develop better products which meet their customers' needs. In most of existing literature, traditional QFD discovers the needs of customers and fulfill them. Yet research and development team can improve QFD tool by adding need creation item so organizations can provide suitable products that cover customers' hidden needs and delight them. This paper presents a new approach that develops quality function deployment through the house of quality matrix expansion. The main innovative idea of the method is the extracting new design requirements (NDRs) without considering CRs in QFD. Analytic network process (ANP) is used to determine relations and correlations between QFD components. The Zero One Goal Programming (ZOGP) is employed in order to prioritize DRs and NDRs by considering additional factors such as manpower constraint, cost budget, extendibility and manufacturability level. Finally the effectiveness of proposed method is illustrated by provided case study.
Thermoresponsive shape memory characteristics of polyurethane electrospun web (2010)

Abstract Electrospun web (ESW) was manufactured and its performance was evaluated to investigate its applicability as an intelligent clothing material using shape memory polymers. Mixtures of various compositions were applied to make the shape memory polyurethane (SMPU) films and the polyurethane with the best shape memory performance was then selected to make the ESWs. The structural and thermal properties, as well as the shape memory behavior were evaluated. The air permeability, the water vapor transmission, and the water resistance were measured. The ESW having a high orientation due to an elongation in the process of the electrospinning showed a higher melting point than the film and its shape recovery was improved. The ESW showed a good moisture and air permeability due to the fact that its structural characteristics incorporate countless nano‐sized pores. Because of this, the ESW maintained in its expanded state below the transition temperature showed improved moisture and air permeabilities. Therefore, it can be concluded that the SMPU web proved to have potential for intelligent clothing material. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
Lateral polysilicon pn diodes: current-voltage characteristics simulation between 200 K and 400 K using a numerical approach (1994)

The current-voltage characteristics of lateral pn diodes fabricated in polysilicon layer grown by LPCVD on oxidized silicon substrates are analyzed versus temperature. The simulation proposed by Greve (1985) using the analytical current modeling is applied to forward and reverse junction currents for various temperatures; this modeling shows its limitations. Then to fit the experimental characteristics at low and high temperatures as well as at low and high current levels, a numerical modeling is developed taking into account the local electrical field effect on recombination and generation mechanisms at grain boundaries in the whole of the structure, i.e., quasi-neutral and depleted regions. This modeling allows one to fit the complete I-V experimental curves in the whole of the considered temperature range (200 K-400 K) with physical acceptable parameters.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Thermodynamics and Kinetics of Pack Aluminide Coating Formation on IN-100 (1974)

The effect of variation of pack activators, compositions, temperature, and time on the thickness and structure of aluminide coatings formed on the nickel‐base superalloy IN‐100 was studied in one‐step packs containing aluminum at unit activity. Times were varied from 4 to 24 hr and temperatures were varied from 982° to 1149°C in ‐activated packs. The other halides of sodium and the ammonium halides were primarily used to activate 1093°C, 16‐hr packs. In addition, an analysis of the thermodynamics and kinetics of aluminizing was carried out. The mechanism of coating formation in each pack was established from agreement between observed coating weights and predictions based on a gaseous diffusion model and solid‐state diffusion considerations which used published diffusion data for the Ni‐Al system. Pack temperature rather than pack aluminum activity controls the principal coating phase formed. The halides ranked according to aluminum weight gain in (weight per cent) Al packs are . Solid‐state nickel diffusion controlled the rate of coating formation in fluoride‐activated packs. Gaseous diffusion controlled the rate of coating formation in bromide‐, iodide‐, and ‐activated packs containing 1 w/o Al. In ‐activated packs containing the ability of the substrate to supply nickel appeared to be in balance with the ability of the pack to supply aluminum. However, the observed rate constant and activation energy indicated that solid‐state diffusion controlled coating growth. Increasing pack aluminum content from 1 to 5 w/o shifted control of coating formation from the gas phase to the solid state in the 16‐hr, 1093°C, ‐activated pack. Regardless of the rate‐controlling step, the kinetics of coating formation were parabolic. The activation energy for coating formation controlled by solid‐state diffusion was . Similar coating microstructures and weight gains were obtained for each halogen regardless of whether its source was a sodium or ammonium halide.
Finding the minimum sampling frequency of multi-band signals: An efficient iterative algorithm (2010)

In this paper, we propose an efficient iterative algorithm for finding the minimum sampling frequency for a signal that consists of multiple bandpass signals. This finds important application in software radio where it is desirable to down-convert multiple bandpass signals simultaneously. We will derive a new set of conditions for alias-free sampling for signals that contain multi-band signals. The conditions can be easily examined with few computations. The minimum sampling frequency can be found by iteratively increasing the sampling frequency to meet the alias-free conditions. The simulations demonstrate that the proposed method requires a much lower complexity than existing algorithms.
A Novel Low-Bit Quantization Strategy for Compressing Deep Neural Networks (2020)

The increase in sophistication of neural network models in recent years has exponentially expanded memory consumption and computational cost, thereby hindering their applications on ASIC, FPGA, and other mobile devices. Therefore, compressing and accelerating the neural networks are necessary. In this study, we introduce a novel strategy to train low-bit networks with weights and activations quantized by several bits and address two corresponding fundamental issues. One is to approximate activations through low-bit discretization for decreasing network computational cost and dot-product memory. The other is to specify weight quantization and update mechanism for discrete weights to avoid gradient mismatch. With quantized low-bit weights and activations, the costly full-precision operation will be replaced by shift operation. We evaluate the proposed method on common datasets, and results show that this method can dramatically compress the neural network with slight accuracy loss.
Antibody Response to <i>Staphylococcus aureus</i> in Rabbits: Sequence of Immunoglobulin Synthesis and Its Correlation with Passive Protection in Mice (1968)

Antibody in hyperimmune rabbit antisera specific for Staphylococcus aureus teichoic acid was shown to be associated with the IgM fraction. Treatment of such sera with mercaptoethanol destroyed its activity in passive mouse protection tests, whereas absorption with antirabbit IgG had no effect. Antibody response in normal rabbits immunized by a single or by three daily injections of a killed vaccine of S. aureus was followed by a sensitive passive hemagglutination test. Antibody detected during the "primary" response was completely susceptible to reduction with mercaptoethanol. Most of the antibody detected after a secondary antigenic stimulation at 10 weeks was also susceptible to mercaptoethanol. The antibody titers correlated well with mouse protective activity, and this activity of the serum was also shown to be associated with the IgM fraction.
Geometry of a Non-Overlapping Multi-Camera Network (2006)

Moving beyond single or stationary camera surveillance systems, we employ an automatically configurable network of non-overlapping cameras. These cameras need not have an overlapping Field of View (FoV) and should be able to move freely in space. In this paper, a practical framework is proposed that determines the geometry of such a dynamic camera network. Assuming each camera in the network is calibrated, it is shown that only one automatically computed vanishing point and a line lying on any plane orthogonal to the vertical direction is sufficient to infer the dynamic network configuration. Our method generalizes previous work which considers restricted camera motions. Using minimal assumptions, we are able to successfully demonstrate promising results on synthetic as well as on real data.
Microstructure and electrical property correlations in Ga:ZnO transparent conducting thin films (2006)

In this paper, we report correlations between processing, microstructure, and electrical properties of Ga doped ZnO films. Films with different grain sizes were grown on amorphous glass substrate by changing the substrate and pulsed laser deposition variables. The results corresponding to these films were compared with those from epitaxial single crystal films grown on (0001) sapphire. Microstructural characteristics were analyzed in detail by using x-ray diffraction and transmission electron microscopy. Electrical properties were evaluated by resistivity measurements in the temperature range of 15–300K and Hall measurements at room temperature. It was observed that the grain boundaries and orientation of grains (texture characteristics) affected the carrier concentration and the mobility considerably in nanocrystalline films deposited on glass substrates. This effect is envisaged to occur as a result of trapping of electrons and buildup of a potential barrier across the grain boundaries. However, the resistivity in nanocrystalline films could be decreased significantly by carefully controlling the deposition conditions. For a film deposited on glass at 200°C and 1mtorr of oxygen partial pressure, we attained a minimum resistivity value of 1.8×10−4Ωcm. The epitaxial films on sapphire substrates showed a resistivity of 1.4×10−4Ωcm, deposited at 400°C and pressure of 2.4×10−2torr. The role of grain boundaries and defects in controlling the carrier generation and transport has been discussed in detail and the possible mechanisms limiting the electrical conductivity in films with different microstructures have also been identified.
