The use of INS/GPS in a highway survey system (2002)

The integration of an inertial navigation system (INS) and Global Positioning System (GPS) receivers in differential mode is investigated for application to highway survey systems. A mobile highway inventory system (MHIS) operated by Alberta Transportation is used as a first step in the realization of an all-purpose kinematic survey system. MHIS requirements of approximately 0.5 m in position, 10 cm-s/sup -1/ in velocity, 0.5% in slope, and 0.2 degrees in curvature appear obtainable with the integrated system. If these requirements can be surpassed, INS/GPS can be used for road surveys, possibly replacing conventional survey techniques. The authors briefly describe the MHIS and outline the benefits of using INS/GPS for accurate and reliable geometric data collection. They outline the mathematical models for INS/GPS integration. Road tests performed using INS/GPS over a well-controlled traverse are discussed, and results are given.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Burn Control by Hydrogen Feeding for Self-Sustained Plasma in Tokamak Fusion Reactors (1986)

The possibility of burn control by hydrogen feeding was investigated for tokamak plasma under a self-sustained condition. When fusion power shifts higher than a target value, increases in hydrogen feed rate can lower the power by a reduction in ion temperature due to enhanced hydrogen density. Conversely, when the power shifts lower than the target, stopping hydrogen feeding and exhaust can increase the power through an increase in ion temperature due to reduced hydrogen density. Especially in the latter, in order to enlarge the recoverable magnitude of power shift, it is necessary to select a self-sustained condition having the highest hydrogen density. The results confirmed the possibility of burn control by hydrogen feeding.
The potential of retro-inverso peptides as synthetic vaccines. (1998)

Retro-inverso (RI) peptides, also called all-D-retro peptides, have been shown to mimic the antigenic and immunogenic properties of L-peptides successfully. RI peptides corresponding to the loop 141-159 of the VP1 protein of foot-and-mouth disease virus (FMDV) have been synthesized and used to immunize rabbits and guinea pigs. These peptides induced longer-lasting and higher antibody titres in immunized animals than did the corresponding L-peptides and the antibodies cross-reacted strongly with virus particles and with L-peptides. Antisera raised to RI peptides had in vitro virus neutralization titres equal to or better than those obtained after immunization with classical FMDV antigens and L-peptides. In view of their increased stability, RI peptides may overcome some of the shortcomings of synthetic viral vaccines based on L-peptides.
Search for a Prion-Specific Nucleic Acid (2005)

Diversity of prion strains was attributed to an elusive nucleic acid, yet a search spanning nearly two decades has failed to identify a prion-specific polynucleotide. In our search for a prion-specific nucleic acid, we analyzed nucleic acids in purified fractions from the brains of Syrian hamsters infected with Sc237 prions. Purification of Sc237 prions removed nucleic acids larger than 50 nucleotides as measured by return refocusing electrophoresis (RRGE). To determine the size of the largest polynucleotide present in purified fractions at an abundance of one molecule per infectious (ID50) unit, we measured prions present after inoculation. In order to account for the rapid clearance of prions after intracerebral inoculation, we determined the number of PrP(Sc) molecules and ID50 units of prions that were retained in brain. Factoring in clearance after inoculation, we estimate that the largest polynucleotide present in our purified fractions at one molecule per ID50 unit is approximately 25 nucleotides in length. In the same fractions, there were approximately 3,000 protease-resistant PrP(Sc) molecules per ID50 unit after accounting for clearance of PrP(Sc) following inoculation. We compared the resistance of Sc237 and 139H prions to inactivation by UV irradiation at 254 nm. Irradiation of homogenates and microsomes diminished prion infectivity by a factor of approximately 1,000 but did not alter the strain-specified properties of the Sc237 and 139H prions. The data reported here combined with the production of synthetic prions argue that the 25-mer polynucleotides found in purified prion preparations are likely to be host encoded and of variable sequence; additionally, these 25-mers are unlikely to be prion specific.
Unresolved endoplasmic reticulum stress engenders immune-resistant, latent pancreatic cancer metastases (2018)

The majority of patients with pancreatic ductal adenocarcinoma (PDA) develop metastatic disease after resection of their primary tumor. We found that livers from patients and mice with PDA harbor single disseminated cancer cells (DCCs) lacking expression of cytokeratin 19 (CK19) and major histocompatibility complex class I (MHCI). We created a mouse model to determine how these DCCs develop. Intraportal injection of immunogenic PDA cells into preimmunized mice seeded livers only with single, nonreplicating DCCs that were CK19<sup>-</sup> and MHCI<sup>-</sup> The DCCs exhibited an endoplasmic reticulum (ER) stress response but paradoxically lacked both inositol-requiring enzyme 1α activation and expression of the spliced form of transcription factor XBP1 (XBP1s). Inducible expression of XBP1s in DCCs, in combination with T cell depletion, stimulated the outgrowth of macrometastatic lesions that expressed CK19 and MHCI. Thus, unresolved ER stress enables DCCs to escape immunity and establish latent metastases.
[POSTER] Tracking and Mapping with a Swarm of Heterogeneous Clients (2015)

In this work, we propose a multi-user system for tracking and mapping, which accommodates mobile clients with different capabilities, mediated by a server capable of providing real-time structure from motion. Clients share their observations of the scene according to their individual capabilities. This can involve only keyframe tracking, but also mapping and map densification, if more computational resources are available. Our contribution is a system architecture that lets heterogeneous clients contribute to a collaborative mapping effort, without prescribing fixed capabilities for the client devices. We investigate the implications that the clients' capabilities have on the collaborative reconstruction effort and its use for AR applications.
A simple surface estimation algorithm for UWB pulse radars based on trilateration (2011)

A simple 3D surface estimation algorithm for ultra-wideband (UWB) pulse radars is presented. This algorithm based on trilateration is easy to implement and needs no preprocessing of measurement data. Mathematical derivations of the formulas for both monostatic and bistatic radar imaging setups are derived. The performance of the proposed algorithm is verified in 3D surface measurements, and a good agreement with well-established methods is shown.
Highly oriented superconducting Tl-Ca-Ba-Cu oxide thin films with 2-1-2-2 phase (1988)

Thin films of the Tl-Ca-Ba-Cu-O system with 2-1-2-2 phase have been prepared stably on MgO substrates by rf magnetron sputtering and post-annealing. The post-annealing of the films was carefully carried out in order to reduce the effect of evaporation of Tl. The annealed films showed a c-axis-oriented structure perpendicular to the substrates. The highest zero-resistance temperature of the films was 102 K. The highest critical current density obtained so far was 1.2×105 A/cm2 at 77 K.
Cellular Differentiation of Sucrose Metabolism in Anabaena variabilis (1985)

Abstract Upon treatment of whole filaments of Anabaena variabilis with a French pressure cell, the activity of sucrose synthase (UDP glucose; D-fructose 2-α-ᴅ-glucosyl transferase, EC 2.4.1.13) was found to be associated almost exclusively with the vegetative cells. The sucrose-cleaving enzyme, an alkaline invertase (β-ᴅ-fructofuranoside fructohydrolase, EC 3.2.1.26), appears to be localized solely within the heterocysts. The implications of these findings, in the light of relevant data from the literature, are summarized in a model representing the physiological differentiation and molecular exchange between vegetative cells and heterocysts.
Growth and properties of doped CdTe films grown by photoassisted molecular-beam epitaxy (1988)

Photoassisted molecular-beam epitaxy (PAMBE), in which the substrate is illuminated during film growth has been successfully employed to prepare n-type CdTe:In and p-type CdTe:Sb films. The n-type layers exhibit large electron mobilities at low temperatures. Field effect transistors have been fabricated from selected CdTe:In layers grown by PAMBE which show good device characteristics. The p-type CdTe:Sb films exhibit bright photoluminescence of excitonic origin at low temperatures. At 300 K, hole mobilities of 81 cm2/V s and carrier concentrations in excess of 1018 cm−3 have been achieved by the PAMBE technique.
Integration of Low-Cost GNSS and Monocular Cameras for Simultaneous Localization and Mapping (2018)

Low-cost Global Navigation Satellite System (GNSS) receivers and monocular cameras are widely used in daily activities. The complementary nature of these two devices is ideal for outdoor navigation. In this paper, we investigate the integration of GNSS and monocular camera measurements in a simultaneous localization and mapping system. The proposed system first aligns the coordinates between two sensors. Subsequently, the measurements are fused by an optimization-based scheme. Our system can function in real-time and obtain the absolute position, scale, and attitude of the vehicle. It achieves a high accuracy without a preset map and also has the capability to work with a preset map. The system can easily be extended to create other forms of maps or for other types of cameras. Experimental results on a popular public dataset are presented to validate the performance of the proposed system.
Automatic Design of Area-Efficient Configurable ASIC Cores (2007)

Reconfigurable hardware has been shown to provide an efficient compromise between the flexibility of software and the performance of hardware. However, even coarse-grained reconfigurable architectures target the general case and miss optimization opportunities present if characteristics of the desired application set are known. Restricting the structure to support a class or a specific set of algorithms can increase efficiency while still providing flexibility within that set. By generating a custom array for a given computation domain, we explore the design space between an ASIC and an FPGA. However, the manual creation of these customized reprogrammable architectures would be a labor-intensive process, leading to high design costs. Instead, we propose automatic reconfigurable architecture generation specialized to given application sets. This paper discusses configurable ASIC (cASIC) architecture generation that creates hardware on average up to 12.3x smaller than an FPGA solution with embedded multipliers and 2.2x smaller than a standard cell implementation of individual circuits
ATP receptors and giant cell formation (1999)

We have investigated the role of the purinergic P2X7 receptor in the formation of multinucleated giant cells in human monocyte/macrophage cultures stimulated with either concanavalin A or phytohemagglutinin. Macrophage fusion can be blocked by a P2X7-selective pharmacological antagonist or by a mAb directed against the extracellular P2X7 domain. Furthermore, macrophage cell clones expressing high P2X7 levels spontaneously fuse in culture, whereas macrophage clones lacking P2X7 are unable to fuse. Our findings suggest that the newly identified purinergic P2X7 receptor plays a central role in the complex chain of events leading to generation of macrophage-derived giant cells.
An Event-Related Potential Study of Emotional Processing to Personal Experience of Everyday Things (2013)

This study used a self-attitude judgment paradigm to investigate the electrophysiological correlates of emotional processing (positive, neutral and negative) to everyday things/ events (objective word). Participants were asked to judge whether they like (positive item) or dislike (negative item) objective word which represented everyday things/events according to their personal experience. Results showed that similar with emotional word; both positive and negative items of objective word elicited a larger late positive component (LPC) than neutral item between 400ms and 700ms, which might reflect recollecting personal experience with special feelings and emotions. This might be the first one to use ERP technique to study the neural basis of emotional processing to personal experience of everyday things/events, and this result supported the idea that emotion feeling might not only be governed by the properties of the stimuli, but also in large part shaped by individual values.
Enantioselective Syntheses of<i>trans</i>-3,4-Difluoropyrrolidines and Investigation of Their Applications in Catalytic Asymmetric Synthesis (2005)

[reaction: see text] Asymmetric syntheses of enantiopure trans-3,4-difluoropyrrolidines have been prepared by the introduction of fluorine at both centers in a single operation; asymmetric epoxidations and additions to benzaldehyde were conducted using catalysts whose chirality depends on organofluorine asymmetry.
<title>Gallium-arsenide electron-bombarded CCD technology</title> (1998)

Electron Bombarded Charge Coupled Devices (EBCCD) which utilize a high performance Gallium Arsenide (GaAs) photocathode have been fabricated and characterized for performance and tube operating life. The EBCCD utilized an 11 mm diagonal, backside illuminated, frame transfer CCD compatible with RS170 video output. The CCD incorporated lateral anti-blooming structures optimized for backside operation. The EBCCD tube was proximity focused and operated with high gain (greater than 150) at low electron landing voltages (less than 2 kV). The EBCCD was integrated in a gated camera system with fast rise and fall times (less than 50 ns). Predicted operating life in a gated camera system as determined by accelerated tests is in excess of 12,000 hours, limited by photocathode degradation.
Photoinduced Release of Zn<sup>2+</sup> with ZinCleav-1: a Nitrobenzyl-Based Caged Complex (2009)

Caged complexes are metal ion chelators that release analytes when exposed to light of a specific wavelength. The synthesis and properties of ZinCleav-1, a cage for Zn(2+) that fragments upon photolysis, is reported. The general uncaging strategy involves integrating a nitrobenzyl group on the backbone of the ligand so that a carbon-heteroatom bond is cleaved by the photoreaction. The caged complex was obtained using a new synthetic strategy involving a Strecker synthesis to prepare a key aldehyde intermediate. ZinCleav-1 has a K(d) of 0.23 pM for Zn(2+) as measured by competitive titration with [Zn(PAR)(2)] (PAR = 4-(2-pyridyl-2-azo) resorcinol). The quantum yield for ZinCleav-1 is 2.4% and 0.55% for the apo and Zn(2+) complex, respectively. The ability of ZinCleav-1 to increase free [Zn(2+)] is calculated theoretically using the binding constants for the uncaged photoproducts, and demonstrated practically by using a fluorescent sensor to image the liberated Zn(2+). Free Zn(2+) may function as a neurotransmitter and have a role in the pathology of several neurological diseases. Studying these physiological functions remains challenging because Zn(2+) is silent to most common spectroscopic techniques. We expect ZinCleav-1 to be the first in a class of caged complexes that will facilitate biological investigations.
Commercial-Scale Control of Rose Powdery Mildew with a Fungal Antagonist (1994)

The yeastlike fungus Sporothrix flocculosa, reported to be antagonistic against several members of the Erysiphales, was used under strict commercial conditions to control rose powdery mildew caused by Sphaerotheca pannosa var. rosae. The antagonist was applied in two separate trials on nearly 1,000 plants of rose cultivars Preference and Samantha, and results were compared with those obtained from plants treated with registered fungicides. In the first trial, treatment with the antagonist exerted control comparable to that of the fungicide, but its efficacy varied with the level of relative humidity prevailing in the greenhouse
A Novel Synthesis of 2‐Aminomethyl‐1,3‐butadienes from <i>N,O</i>‐Acetals (1990)

The synthesis of 2-aminomethyl-1,3-butadienes 3 can be achieved surprisingly easily, namely from unsaturated N,O-acetals 1 under the conditions of base-catalyzed CC isomerization. β-Aminocarbonyl compounds 2 probably occur as intermediates, which are formed by a hovel variant of the intramolecular Mannich reaction.
Polyphone decision tree specialization for language adaptation (2002)

With the distribution of speech technology products all over the world, the fast and efficient portability to new target languages becomes a practical concern. The authors explore the relative effectiveness of adapting multilingual LVCSR systems to a new target language with limited adaptation data. For this purpose they introduce a polyphone decision tree specialization method. Several recognition results are presented based on mono- and multilingual recognizers. These recognizers are developed in the framework of the project GlobalPhone. In this project we investigate speech recognition in 15 languages: Arabic, Mandarin and Shanghai Chinese, Croatian, English, French, German, Japanese, Korean, Portuguese, Russian, Spanish, Swedish, Tamil, and Turkish.
Characterization of a novel low-molecular-mass dual-specificity phosphatase-3 (LDP-3) that enhances activation of JNK and p38 (2004)

We have isolated a mouse cDNA for a novel dual-specificity phosphatase designated LDP-3 (low-molecular-mass dual-specificity phosphatase 3). The 450 bp open reading frame encodes a protein of 150 amino acids with a predicted molecular mass of 16 kDa. Northern blot and reverse transcription-PCR analyses show that LDP-3 transcripts are expressed in almost all mouse tissues examined. In vitro analyses using several substrates and inhibitors indicate that LDP-3 possesses intrinsic dual-specificity phosphatase activity. When expressed in mammalian cells, LDP-3 protein is localized mainly to the apical submembrane area. Forced expression of LDP-3 does not alter activation of ERK (extracellular-signal-regulated kinase), but rather enhances activation of JNK (c-Jun N-terminal kinase) and p38 and their respective upstream kinases MKK4 (mitogen-activated protein kinase kinase 4) and MKK6 in cells treated with 0.4 M sorbitol. By screening with a variety of stimuli, we found that LDP-3 specifically enhances the osmotic stress-induced activation of JNK and p38.

Ultrathin Coatings on Nano-LiCoO<sub>2</sub>for Li-Ion Vehicular Applications (2010)

To deploy Li-ion batteries in next-generation vehicles, it is essential to develop electrodes with durability, high energy density, and high power. Here we report a breakthrough in controlled full-electrode nanoscale coatings that enables nanosized materials to cycle with durable high energy and remarkable rate performance. The nanoparticle electrodes are coated with Al(2)O(3) using atomic layer deposition (ALD). The coated nano-LiCoO(2) electrodes with 2 ALD cycles deliver a discharge capacity of 133 mAh/g with currents of 1400 mA/g (7.8C), corresponding to a 250% improvement in reversible capacity compared to bare nanoparticles (br-nLCO), when cycled at this high rate. The simple ALD process is broadly applicable and provides new opportunities for the battery industry to design other novel nanostructured electrodes that are highly durable even while cycling at high rate.

The weight per cent composition of this Tic‐base cermet is 55.4 TIC + 17.9 TiB 2 + 16.7 Co + 10 Si, and the principal phases present after sintering are Tic, TiB 2 , and CoSi. The research on and development of this material and some of its physical properties are discussed.
European Music Archaeology Project (EMAP): Ein internationales Kooperationsprojekt, gefördert durch die EACEA (2017)

The European Music Archaeology Project (EMAP) is an international cooperation project funded by the Education, Audiovisual and Culture Executive Agency of the European Union for the period of five years (summer 2013 to summer 2018), and to which the Orient Department of the German Archaeological Institute is one of ten cooperation partners. The goal of the project is to combine research on the musical instruments of the archaeological cultures of the European continent, with special reference to the possible exchange of musical knowledge between individual cultures and through the times, and to present the results in a travelling multimedia exhibition. The study of manufacturing techniques and possible playing techniques in the course of the project results in playable replicas for the exhibition and concerts.
Interaction of Aspirin (Acetylsalicylic Acid) with Lipid Membranes (2012)

We studied the interaction of Aspirin (acetylsalicylic acid) with lipid membranes using x-ray diffraction for bilayers containing up to 50 mol% of aspirin. From 2D x-ray intensity maps that cover large areas of reciprocal space we determined the position of the ASA molecules in the phospholipid bilayers and the molecular arrangement of the molecules in the plane of the membranes. We present direct experimental evidence that ASA molecules participate in saturated lipid bilayers of DMPC (1,2-dimyristoyl-sn-glycero-3-phosphocholine) and preferably reside in the head group region of the membrane. Up to 50 mol% ASA molecules can be dissolved in this type of bilayer before the lateral membrane organization is disturbed and the membranes are found to form an ordered, 2D crystal-like structure. Furthermore, ASA and cholesterol were found to co-exist in saturated lipid bilayers, with the ASA molecules residing in the head group region and the cholesterol molecules participating in the hydrophobic membrane core.
