VidLoc: 6-DoF Video-Clip Relocalization. (2017)

Machine learning techniques, namely convolutional neural
networks (CNN) and regression forests, have recently
shown great promise in performing 6-DoF localization
of monocular images. However, in most cases imagesequences,
rather only single images, are readily available.
To this extent, none of the proposed learning-based
approaches exploit the valuable constraint of temporal
smoothness, often leading to situations where the per-frame
error is larger than the camera motion. In this paper we
propose a recurrent model for performing 6-DoF localization
of video-clips. We find that, even by considering
only short sequences (20 frames), the pose estimates are
smoothed and the localization error can be drastically reduced.
Finally, we consider means of obtaining probabilistic
pose estimates from our model. We evaluate our method
on openly-available real-world autonomous driving and indoor
localization datasets.
Embedded end-to-end wireless security with ECDH key exchange (2006)

Sensor networks offer tremendous benefits for the future as they have the potential to make life more convenient and safer. For instance, sensors can be used for climate control to reduce power consumption, for structures such as bridges to monitor the maintenance status, or for company badges to locate employees in order to increase productivity. However, the introduction of such ubiquitous computing to everyday life also raises privacy concerns. In this work the authors presented a public-key cryptography implementation for secure key exchange on low-end wireless devices using elliptic curves. The implementation is based on optimal extension fields (OEF) that are a special type of finite fields GF(p/sup m/). As for the platform, the authors chose a Chipcon CC1010 chip which is based on the 8051 architecture and that is especially suited for secure wireless applications as it has a built-in radio transceiver as well as a hardware DES engine. A secure end-to-end connection was established between the sensor and a base station in an acceptable time of 3 seconds without requiring cryptographic coprocessors.
A VLSI Design of a Radix-4 Floating Point FFT Butterfly (1991)

Cyclic Spectrum Analysis is used to exploit the cyclostationary properties of signals and systems. Implementing such a system will require high speed arithmetic processing. Investigations into high speed arithmetic and FFT design are conducted. Integrated circuits of a 45 MHz floating point multiplier, adder, and rate-1/4 radix-4 FFT butterfly, implemented with a 20-bit word size, are presented using the Genesil Silicon Compiler.
PREDICTING THERMAL CRACKING OF PAVEMENTS FROM BINDER PROPERTIES: THEORETICAL BASIS AND FIELD VALIDATION (2000)

The main objective of this paper is to describe the development of a comprehensive semi-empirical mechanistic mode to determine the critical cracking temperature of asphalt pavements. This model uses stiffness data from the Bending Beam Rheometer (BBR) to predict thermal stress in binder. The thermal stress in the hot-mix pavement is computed using a damage transfer function called the Pavement Constant (PC). To determine critical cracking temperature , the pavement thermal stress is compared with the binder tensile strength measured using the Direct Tension Test (DTT). This model was used to develop a low-temperature criterion for use as a binder specification. In this specification, the low-temperature binder performance grade is determined by comparing the thermal stress in the pavement with the binder failure stress. If the binder failure stress exceeds the thermal stress at the specification temperature, the binder is considered a pass. The semi-empirical model was calibrated using the binder properties and the hot-mix properties from the Lamont Test Road in Alberta, Canada. Further validation was obtained from analysis of the Elk County Test Road in Pennsylvania, as well as for two widely used polymer-modified asphalts with anecdotal, but extensive, performance data.
Dominance of a single peptide bound to the class I(B) molecule, Qa-1b (1997)

One of the hallmarks of class I(A) molecules is their ability to bind and present a wide array of peptides to CD8 T cells. This diversity is consistent with their ability to restrict a variety of pathogenic peptide epitopes as well as elicit strong transplantation responses. In contrast, class I(B) molecules appear to be involved in presentation of pathogenic epitopes to a relatively lesser extent as well as play a minor role in transplantation responses. Here we have examined the peptides bound and presented by the class I(B) molecule Qa-1b in order to determine if their diversity was similar to that reported for class I(A) Ags. First, we show that bulk-cultured anti-Qa-1b CTL predominantly recognize a single peptide (Qdm) derived from the leader segment of class I(A) alloantigens. These CTL are peptide specific and reflect the activity of previously described CTL clones. Second, we find approximately 4.6 x 10(4) copies of the Qdm peptide/cell. Most of the peptide is Qa-1b associated since the recovery of this peptide from anti-Qa-1b immunoprecipitates is approximately 75% of that seen in whole cell extracts and no detectable activity is observed in Kb or Db extracts from H-2b lymphoblasts. Third, the expression of Qa-1b on lymphoblasts is approximately 1 to 1.25 x 10(4) molecules/cell indicating that the Qdm peptide must be derived from both cell membrane and intracellular compartments. Finally, examination of the diversity of peptides associated with Qa-1b as determined by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry indicates few detectable peptide species associated with this molecule. Taken together, Qa-1b appears to predominantly bind a single peptide species that is recognized by alloreactive CD8 T cells. This feature may account, in part, for the class I(B) properties of this molecule.
Einleitung (1994)

Was ist Verantwortung? Politiker reden von Verantwortung, desgleichen Eltern und Unternehmer. Verantwortung wird, wie man weiß, oft mißbraucht, und so wie man Verantwortung haben, übernehmen, entziehen kann, kann man sie ab­lehnen, von sich weisen, anderen aufbürden... Bekanntlich tragen Eltern die Verantwortung für ihre Kinder, man kennt Verantwortung unter Partnern, des Arztes für den Patienten, des Staates für seine Bürger; selbst Fremden gegenüber kann uns die Verantwortung auferlegt werden. Manche sprechen sogar von Ver­antwortung für die Natur, oder vor Gott. Aber, was ist Verantwortung?
Multiples: Signal or noise? (2016)

ABSTRACT Migration and migration inversion are the seismic processing methods for structural determination and subsequent amplitude analysis, respectively. To date, the most well-founded and physically interpretable migration method is based on predicting a coincident source and receiver experiment at depth at time equals zero. We have extended that migration method for heterogeneous media and to accommodate two-way propagation in a local sense at every point from the source to the target reflector and back from the reflector to the receiver and in a global sense, separately for each of the two legs from the source to the reflector and from the reflector to the receiver. That provides the first migration method that avoids high-frequency assumptions in the imaging principle and how it is implemented, and hence, it is equally effective at all frequencies at the target or reservoir. This advance for two-way wave propagation migration then provides a tool to quantitatively, unambiguously, and definitively define the role of primaries and multiples in migration. Our conclusion was that with data consisting of primaries and multiples, for an accurate discontinuous velocity model, only primaries contribute to migration with the same image and inversion results independent of whether multiples are kept or removed. However, for a smooth and continuous velocity model (i.e., generally assumed in practice), every multiple will result in a false, misleading, and potentially injurious subsurface image and hence must be removed before migration. In practice, we migrate with a smooth velocity model, and hence multiples must be removed. When the collection of primaries is incomplete, a multiple can be used to provide an approximate image of an unrecorded primary. However, it is always the migration of primaries that provides subsurface structure and amplitude information.
Structural interaction of natural and synthetic inhibitors with the venom metalloproteinase, atrolysin C (form d). (1994)

The structure of the metalloproteinase and hemorrhagic toxin atrolysin C form d (EC 3.4.24.42), from the venom of the western diamondback rattlesnake Crotalus atrox, has been determined to atomic resolution by x-ray crystallographic methods. This study illuminates the nature of inhibitor binding with natural (< Glu-Asn-Trp, where < Glu is pyroglutamic acid) and synthetic (SCH 47890) ligands. The primary specificity pocket is exceptionally deep; the nature of inhibitor and productive substrate binding is discussed. Insights gained from the study of these complexes facilitate the design of potential drugs to treat diseases where matrix metalloproteinases have been implicated, e.g., arthritis and tumor metastasis.
Delta flashing of an ECU in the automotive industry (2016)

This paper has the purpose of describing a new approach on firmware update on automotive ECUs. The firmware update process for certain automotive ECUs requires excessive time through the CAN bus. By using the delta flashing concept, firmware update time can be greatly reduced by reducing the quantity of the data that is transmitted over the network.
Molecular Beam Laser Saturation Spectroscopy (1987)

Laser saturation spectroscopy on particle beams is demonstrated as a new sub-Doppler technique. It offers unique advantages regarding resolution and intensity.
EXTRA-EM: extraction of temperature and resistance for acceleration of electromigration at wafer-level (2002)

A thermal model and a control algorithm are developed for rapid electromigration (EM), which extracts both temperature and resistance for acceleration (EXTRA) from a standard wafer-level electromigration acceleration test (SWEAT) test structure. SWEAT structure complexity makes determination of the temperature and resistance during the execution of stress very difficult. The originally developed SWEAT thermal model is inaccurate because it cannot separate temperature changes from EM voiding, and this adds variability to failure distributions. EXTRA uses heat flow characteristics from individual structure regions to provide (1) narrow region temperature separated from resistance changes due to voiding, (2) rapid stress convergence, (3) stress control without empirically derived software, and (4) overall reduced variability in failure distributions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Analysis and experiment of a wideband phased array of monopole excited parallel plate waveguides (2003)

Recently, J.B. Jaro, S.R. Laxipati, and B.D. Wright (1987 IEEE AP-S Int. Symp. Int., p.290-394) presented an experimental investigation on a wideband phased array of coaxially fed probes in parallel-plate waveguides. Their measured results showed a design with aperture match over +or-60 degrees in E- and H-plane scanning over 40% frequency bandwidth. In the present work, the authors provide a modal analysis of this wideband phased array of monopole excited parallel-plate waveguides and a comparison of the numerical results with experimental results obtained by the measurements of waveguide simulators and a 9*9 test array. The numerical results are in agreement with the experimental data. An example design confirms that the array can be matched over +or-60 degrees scan coverage over a 40% frequency bandwidth.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Effect of Sinomerine on Antibody Responses in Mice (1985)

Sinomenine, an epimorphinan alkaloid, was tested for the immunosuppressive effect in mice. This compound produced a decrease of plaque-forming cells (PFC) to a T cell-dependent antigen, sheep red blood cells, in vivo. The depression of the PFC response induced with sinomenine was dose and time dependent. On the other hand, it failed to suppress the PFC response to a T cell-independent antigen, lipopolysaccharide. The immunosuppressive dose of sinomenine did not alter the cellularity of spleen, thymus, bone marrow and peripheral blood leucocytes, the DNA synthesis activity of bone marrow cells nor the proliferative responses of spleen cells induced by T cell and B cell mitogens in unprimed mice. These data suggest a selective effect of sinomenine on lymphoid cells. This compound has a potential for use in studies of immuno-deficiencies or clarifying some aspect of immunity.
Copper diffusion and mechanical toughness at Cu-silica interfaces glued with polyelectrolyte nanolayers (2007)

We demonstrate the use of polyallylamine hydrochloride (PAH)-polystyrene sulfonate (PSS) nanolayers to block Cu transport into silica. Cu/PSS-PAH/SiO2 structures show fourfold enhancement in device failure times during bias thermal annealing at 200 °C at an applied electric field of 2 MV/cm, when compared with structures with pristine Cu-SiO2 interfaces. Although the bonding at both Cu-PSS and PAH-SiO2 interfaces are strong, the interfacial toughness measured by the four-point bend tests is ∼2 Jm−2. Spectroscopic analysis of fracture surfaces reveals that weak electrostatic bonding at the PSS-PAH interface is responsible for the low toughness. Similar behavior is observed for Cu-SiO2 interfaces modified with other polyelectrolyte bilayers that inhibit Cu diffusion. Thus, while strong bonding at Cu-barrier and barrier-dielectric interfaces may be sufficient for blocking copper transport across polyelectrolyte bilayers, strong interlayer molecular bonding is a necessary condition for interface toughening. These findings are of importance for harnessing MNLs for use in future device wiring applications.

γ-Glutamyltransferase is not involved in the bulk uptake of amino acids, peptides or γ-glutamyl-amino acids in yeast (<i>Saccharomyces cerevisiae</i>) (1984)

gamma-Glutamyltransferase activity has been measured in yeast (Saccharomyces cerevisiae) and shown to be associated mainly with the membrane fraction. A similar level of activity is found in a wild-type strain and in gap and gpp strains, the latter mutants being defective in the general amino acid and peptide permeases respectively. The activity is inhibited in whole cells by 6-diazo-5-oxo-L-norleucine (N2O-Nle), azaserine and serine-borate complex; this inactivation seemingly acts from without, for it is similar in (i) control and dicyclohexylcarbodi-imide-treated cells and in (ii) the wild-type and a gap mutant, a treatment and a mutation that it has been shown prevents uptake of the inhibitors. Thus a major portion of the gamma-glutamyltransferase activity appears to exist in a membrane-bound form that is orientated with its gamma-glutamyl-binding site facing the outside. Yeast cells in which gamma-glutamyltransferase has been inactivated by N2O-Nle show no significant change in their rates of uptake of a variety of amino acids, dipeptides and gamma-glutamyl-amino acids. The results preclude a major, direct role for gamma-glutamyltransferase in the transport of these substrates.
In vivo compressibility of the human fingertip (1992)

During manual exploration or manipulation of objects by humans, the mechanical properties of the fingerpads play a dominant role in governing the sensing of tactile information as well as the control of manipulation. To determine the in vivo compressibility of human fingertips, static indentation experiments were performed using a specially designed apparatus. Volume changes of the fingertips were measured at various depths of indentation by a sharp probe. The results show that the fingertip is almost incompressible for a point indentor, with the highest change in volume (about 1%) occurring at the largest depth of indentation (4 mm). This data is being used in the development of reliable mechanistic models of the fingertip to gain a deeper understanding of the biomechanical bases of tactile sense.
Ecology of Iron-Oxidizing Bacteria in Pyritic Materials Associated with Coal (1974)

A technique was developed for measuring (14)CO(2) uptake by chemolithotrophic bacteria directly in pyritic materials associated with coal and coal refuse. There was good correlation between (14)CO(2) uptake, as determined by this technique, and the most probable number of iron-oxidizing bacteria. Maximal (14)CO(2) uptake occurred in coal refuse material 2 to 3 years old, and only slight incorporation was demonstrated in fresh material or material 40 years old. Samples taken from the surface of the coal refuse pile always demonstrated maximal (14)CO(2) uptake, and in most samples, only slight activity was demonstrated at depths below 8 to 10 cm. Optimal uptake of (14)CO(2) by natural samples occurred at 20 to 30 C and at a moisture content of between 23 and 35%. In addition to chemolithotrophic bacteria, heterotrophic fungi and yeasts were also routinely isolated in high numbers from acidic coal refuse. In contrast, acidophilic, heterotrophic bacteria were either absent or present in low numbers in such acidic samples.
<i>aph-2</i> encodes a novel extracellular protein required for GLP-1-mediated signaling (2000)

In animal development, numerous cell-cell interactions are mediated by the GLP-1/LIN-12/NOTCH family of transmembrane receptors. These proteins function in a signaling pathway that appears to be conserved from nematodes to humans. We show here that the aph-2 gene is a new component of the GLP-1 signaling pathway in the early Caenorhabditis elegans embryo, and that proteins with sequence similarity to the APH-2 protein are found in Drosophila and vertebrates. During the GLP-1-mediated cell interactions in the C. elegans embryo, APH-2 is associated with the cell surfaces of both the signaling, and the responding, blastomeres. Analysis of chimeric embryos that are composed of aph-2(+) and aph-2(-) blastomeres suggests that aph-2(+) function may be provided by either the signaling or responding blastomere.
VINYLBORANE FORMATION IN RHODIUM-CATALYZED HYDROBORATIONS - LIGAND-FREE HOMOGENEOUS CATALYSIS (1992)

The reaction of vinylarenes with oxazaborolidine 4 catalysed by (bis-alkene) rhodium chloride complexes leads exclusively to coproduction of (E)-vinylborane and ethylarene.
Digital imaging colposcopy, image analysis and quantification of the colposcopic image (1994)

Digital imaging colposcopy allows image capture, processing and objective analysis. This methodology holds advantages for basic and clinical research, teaching, diagnostics and clinical audit. The system can act as a quality control tool for colposcopy units. This system should prove invaluable for further quantitative studies, for natural history studies and for those patients with deferred treatment of their cytological and colposcopic abnormalities. The statistical models described may be incorporated into the system and can aid the colposcopist in management of the woman with abnormal cervical cytology and colposcopic abnormality.
Overview of Planar SOFC Development at NCLI (1989)

This paper summarizes the present status of investigation on solid oxide fuel cell (SOFC) at National Chemical Laboratory for Industry (NCLI). The main target of the investigation is to clarify the possibility of a large planar SOFC, which is suitable for on-site power generation (10 – 100 MW). Emphases were placed on the following points.
BALANCE DE LOS ESTUDIOS SOBRE LAS RELACIONES ENTRE CONFLICTO ARMADO Y DESPLAZAMIENTO FORZADO EN ANTIOQUIA, 2000-2012 (2014)

En este articulo se presenta el estado del arte sobre los estudios que analizan las relaciones entre conflicto armado y desplazamiento forzado en el departamento de Antioquia, referidos al periodo 2000-2012. Luego de presentar los aspectos generales de los trabajos, los ejes tematicos, los tipos de estudios y los aportes analiticos y conceptuales, se realiza un balance general de los mismos en clave de proponer una posible agenda investigativa sobre el tema. Se concluye que, no obstante los significativos avances en la identificacion de dos importantes lineas de investigacion – i) Relaciones entre conflicto armado y desplazamiento forzado, ii) Relaciones entre desarrollo, conflicto armado y desplazamiento forzado-, se debe profundizar en dichos estudios, toda vez que el problema del desplazamiento forzado sigue estando latente. Asimismo es necesario estudiar otros asuntoscomo las relaciones con el sistema electoral y con el aparato de justicia.Finalmente, es perentorio realizar investigaciones que profundicenen el analisis de las relaciones entre desarrollo, conflicto y desplazamientoen los entornos urbanos, principalmente en la ciudad deMedellin, donde han permanecido en la oscuridad los posibles nexosentre violencia y desarrollo.
Hijacking of Lipid Droplets by Hepatitis C, Dengue and Zika Viruses—From Viral Protein Moonlighting to Extracellular Release (2020)

Hijacking and manipulation of host cell biosynthetic pathways by human enveloped viruses are essential for the viral lifecycle. <i>Flaviviridae</i> members, including hepatitis C, dengue and Zika viruses, extensively manipulate host lipid metabolism, underlining the importance of lipid droplets (LDs) in viral infection. LDs are dynamic cytoplasmic organelles that can act as sequestration platforms for a unique subset of host and viral proteins. Transient recruitment and mobilization of proteins to LDs during viral infection impacts host-cell biological properties, LD functionality and canonical protein functions. Notably, recent studies identified LDs in the nucleus and also identified that LDs are transported extracellularly via an autophagy-mediated mechanism, indicating a novel role for autophagy in <i>Flaviviridae</i> infections. These developments underline an unsuspected diversity and localization of LDs and potential moonlighting functions of LD-associated proteins during infection. This review summarizes recent breakthroughs concerning the LD hijacking activities of hepatitis C, dengue and Zika viruses and potential roles of cytoplasmic, nuclear and extracellular LD-associated viral proteins during infection.
Incorporating fisheyeing into a visual programming environment (2002)

Fisheyeing, in combination with zooming, addresses the scalability problem in visual languages by allowing the user to see a portion of a large visual program in detail while at the same time viewing the remainder of the program in somewhat less detail. We describe how fisheye views have been incorporated in the VIPR (VIsual PRogramming) environment. We begin by discussing the ways in which VIPR is amenable to fisheyeing techniques, and present a scenario illustrating the ways in which fisheyeing may be used in navigating and comprehending a VIPR program. We then discuss the particular requirements placed on a fisheyeing technique by VIPR, and present an implementation that meets those requirements.
Operational Application of Meteorological Doppler Radar (1980)

Single Doppier weather radar velocity and reflectivity fields have been obtained with the National Center for Atmospheric Research (NCAR) 5 cm radars for a wide variety of weather situations. Among those weather features that can be identified by means of color displays are the vertical variation of wind with height in widespread precipitation, frontal boundaries, gust fronts, "downbursts," tornadoes, hurricane winds, wind shears dangerous to aircraft, and winds in the boundary layer in clear air.
