Integrity Monitoring for Multiple Errors in Vision Navigation Systems (2013)

In aviation applications, navigation integrity is paramount. Integrity of GPS systems is well established with set standards. Vision-based navigation systems have been found to be an adequate substitute for GPS when it is unavailable but are unlikely to be utilized until there is a measure for system integrity. Work has been done to detect the effect of a single measurement pair being corrupted with a bias; however, the measurement geometry varies greatly with the environment. The environment could be sparse in visual features to track, or the environment could be rich with features. With more features, there is a greater probability of having multiple corrupted measurements. It is essential that multiple corrupt measurements are detected and excluded to assure the integrity and reliability of the system. In addition, misalignment errors in the camera system results in systematic errors that are undetectable by current methods. This dissertation focuses on understanding the existing integrity monitoring methods and using them for the detection of multiple errors in vision-based navigation systems, as well as, developing a technique for detecting systematic errors due to camera misalignment and scaling. These methods are developed analytically and verified by using simulations. These simulations serve to demonstrate the usefulness of these methods in achieving the goal of this research to further the area of integrity monitoring for vision systems, so it could eventually be used as a trusted system and as a back-up for GPS navigation.
Endovascular Repair of Thoracic Aortic Disease With the EndoFit Stent-Graft:<b>Short and Midterm Results From a Single Center</b> (2008)

Endovascular treatment of vascular disease involving the descending thoracic aorta can be safely performed with the EndoFit thoracic stent-graft system.
Completeness criteria in many-valued set logic under compositions with Boolean functions (2002)

Discusses the functional completeness problems in r-valued set logic, which is the logic of functions mapping n-tuples of subsets into subsets over r values. Boolean functions are convenient choice as building blocks in the design of set logic functions. A set of functions F is Boolean complete if any set logic function can be composed from F once all Boolean functions are added to F. The paper proves that there are 2/sup r/-2 Boolean maximal sets in r-valued set logic and gives their description using equivalence relations. A set F is then Boolean complete if it is not a subset of any of these 2/sup r/-2 Boolean maximal sets, which is a completeness criteria in many-valued set logic under compositions with Boolean functions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A raster multibeam lithography tool for sub-100-nm mask fabrication utilizing a novel photocathode (2003)

A raster multibeam lithography tool is in Etec’s roadmap to meet the stringent requirements of sub 100 nm mask fabrication. The tool leverages the long experience obtained with the ALTA laser pattern generators and the high resolution capabilities of e-beam lithography. A photocathode controlled by acousto-optic modulated 257nm laser beams is utilized to generate 32 electron beams. The beams are accelerated at 50 KV in an electron column, demagnified and focussed on the mask or wafer substrate. The performance of the photocathode and other system components will be presented together with preliminary lithographic patterning.
Escherichia coli has two homologous glutamate decarboxylase genes that map to distinct loci (1992)

Degenerate oligonucleotides based on the published Escherichia coli glutamate decarboxylase (GAD) protein sequence were used in a polymerase chain reaction to generate a DNA probe for the E. coli GAD structural gene. Southern blots showed that there were two cross-hybridizing GAD genes, and both of these were cloned and sequenced. The two GAD structural genes, designated gadA and gadB, were found to be 98% similar at the nucleotide level. Each gene encoded a 466-residue polypeptide, named, respectively, GAD alpha and GAD beta, and these differed by only five amino acids. Both GAD alpha and GAD beta contain amino acid residues which are highly conserved among pyridoxal-dependent decarboxylases, but otherwise the protein sequences were not homologous to any other known proteins. By restriction mapping and hybridization to the Kohara miniset library, the two GAD genes were located on the E. coli chromosome. gadA maps at 4046 kb and gadB at 1588 kb. Neither of these positions is in agreement with the current map position for gadS as determined by genetic means. Analysis of Southern blots indicated that two GAD genes were present in all E. coli strains examined, including representatives from the ECOR collection. However, no significant cross-hybridizing gene was found in Salmonella species. Information about the DNA sequences and map positions of gadA and gadB should facilitate a genetic approach to elucidate the role of GAD in E. coli metabolism.
Inocuidad de lactobacilos potencialmente probióticos aislados de heces de lactante y leche materna. (2013)

Lactobacillus belongs to the Acid Lactic Bacteria group, which is known for their probiotic properties. These microorganisms are historically considered safe for their close association with food, they are inhabitants of the normal indigenous microbiota and their pathogenic potential is low. The objective of the present study was to evaluate the safety of potentially probiotic lactobacilli strains, isolated from breast-fed infant stools and breast milk in Merida, Venezuela, through a bacterial translocation assay on liver and spleen. Two strains of Lactobacillus paracasei ssp. paracasei (66 and 71) and one strain of L. rhamnosus (75) were evaluated; these strains were described as potential probiotics microorganism according previous in vitro tests. Bacteria were orally administrated to BALB/c mice for 7 days. ANOVA one way test was used to assess the statistical significance of the differences between test and control groups. There were no significant differences in bacterial  growth of liver and spleen between control mice and those receiving oral administration of lactobacilli strains. Therefore these strains are likely to be safe for human consumption.

Where-what network 1: &#x201C;Where&#x201D; and &#x201C;what&#x201D; assist each other through top-down connections (2008)

This paper describes the design of a single learning network that integrates both object location (ldquowhererdquo) and object type (ldquowhatrdquo), from images of learned objects in natural complex backgrounds. The in-place learning algorithm is used to develop the internal representation (including synaptic bottom-up and top-down weights of every neuron) in the network, such that every neuron is responsible for the learning of its own signal processing characteristics within its connected network environment, through interactions with other neurons in the same layer. In contrast with the previous fully connected MILN [13], the cells in each layer are locally connected in the network. Local analysis is achieved through multi-scale receptive fields, with increasing sizes of perception from earlier to later layers. The results of the experiments showed how one type of information (ldquowhererdquo or ldquowhatrdquo) assists the network to suppress irrelevant information from background (from ldquowhererdquo) or irrelevant object information (from ldquowhatrdquo), so as to give the required missing information (ldquowhererdquo or ldquowhatrdquo) in the motor output.
Quantifying Uncertainties Associated With Reservoir Simulation Studies Using Surrogate Reservoir Models (2006)

Abstract Reservoir simulation is routinely used as a reservoir management tool. The static model that is used as the basis for simulation is the result of an integrated effort that usually includes the latest geological, geophysical and petro-physical measurements and interpretations. As such, it is inherently a model with some uncertainty. Analysis of these uncertainties and quantification of their effects on oil production and water cut using a new and efficient technique is the subject of this paper. Typical uncertainty analysis techniques require many realizations and runs of the reservoir model. In the day and age that reservoir models are getting larger and more complicated, making hundreds or sometimes thousands of simulation runs can put considerable strain on the resources of an asset team. This paper summarizes the results of uncertainty analysis on a giant oil field in the Middle East using a new technique that incorporates a Surrogate Reservoir Model (SRM). A Surrogate Reservoir Model that runs and provides results in real-time is developed to mimic the capabilities of a full field model that includes about one million grid blocks and takes 10 hours to run on a cluster of twelve 3.2 GHz CPUs. This Surrogate Reservoir Model is used as the objective function of a Monte Carlo Simulation to study the impact of the uncertainties associated with several parameters on the model outcome, i.e. oil production and water cut is analyzed. The analysis can be performed individually on each of the 165 horizontal wells. During the analyses of uncertainty, the Surrogate Reservoir Model will serve as an objective function for the Monte Carlo Simulation. In this study, uncertainties associated with several reservoir parameterts and their quantitative effect on cumulative oil production and stantaneous water cut are examined.
Analysis of LoRaWAN v1.1 security (2018)

LoRa and the LoRaWAN specification is a technology for Low Power Wide Area Networks (LPWAN) designed to allow connectivity for connected objects, such as remote sensors. Several previous works revealed various weaknesses regarding the security of LoRaWAN v1.0 (the official 1st draft) and these led to improvements included in LoRaWAN v1.1, released on Oct 11, 2017. In this work, we provide the first look into the security of LoRaWAN v1.1. We present an overview of the protocol and, importantly, present several threats to this new version of the protocol. Besides, we propose our own ramification strategies for the mentioned threats, to be used in developing next version of LoRaWAN. The threats presented were not previously discussed, they are possible even within the security assumptions of the specification and are relevant for practitioners implementing LoRa-based applications as well researchers and the future evolution of the LoRaWAN specification.
Thin-film adhesion (1974)

Adhesion is of vital interest in thin-film science because the fragile film relies on the underlying substrate, and the adhesion between the two for durability. In addition, the formation and structure of the film depend on the adhesive interaction between the depositing material and the substrate. Despite its general relevance, adhesion is one of the aspects of thin-film science about which little is known. A considerable problem arises with the measurement of adhesion, or more precisely with its lack of susceptibility to measurement. The approaches that have been used are reviewed. A further problem is concerned with the meaning and relevance of “adhesion”, and this point will be discussed from both the practical and theoretical points of view. Based as much on empiricism as on understanding, some means of modifying adhesion have been found and these also are reviewed.
Purification and Characterization of Dipeptidyl Peptidase IV in Rat Liver Lysosomal Membranes1 (1992)

Dipeptidyl peptidase IV (m-DPP IV) in rat liver lysosomal membranes was purified about 50-fold over the lysosomal membranes with 38% recovery to apparent homogeneity, as determined from the pattern on polyacrylamide gel electrophoresis in the presence and in the absence of SDS. The enzyme amounts to about 3% of lysosomal membrane protein constituents. The purification procedures included: extraction of lysosomal membranes by Triton X-100, WGA-Sepharose affinity chromatography, hydroxylapatite chromatography, ion exchange chromatography, and preparative polyacrylamide gel electrophoresis. The enzyme (M(r) 240,000) is composed of two identical subunits with an apparent molecular weight of 110,000. The enzyme contains about 12.4% carbohydrate and the carbohydrate moiety was composed of mannose, galactose, fucose, N-acetylglucosamine, and neuraminic acid in a molar ratio of 14:17:2:24:11. Susceptibility to neuraminidase and immunoreactivity of the enzyme in intact tritosomes were examined to study the topology of the enzyme in tritosomal membranes. Neuraminidase susceptibility and immunoreactivity of the enzyme were not observed in the intact tritosomes until the tritosomes had been disrupted by osmotic shock. This result indicated that both the oligosaccharide chains and the main protein portion of the enzyme are on the inside surface of the tritosomal membranes. Subcellular localization of DPP IV was determined by means of enzyme immunoassay, which indicated that bile canalicular membranes and lysosomal membranes are the major sites of localization, and DPP IV activity in lysosomes was separated into a membrane bound form (60%) and a soluble form (40%). Immunoelectron microscopy clearly confirmed that DPP IV occurs not only in the bile canalicular domain but also in the lysosomes of rat liver.
Cross field injection and trapping of a continuous plasma beam in a magnetic mirror (1983)

A beam of potassium plasma of 1012 cm-3 density from a continuous magnetoplasma-dynamic arc source has been propagated into a magnetic mirror device in a direction transverse to the magnetic field. A self induced polarization and E*B drift of the beam was observed. The plasma filled the magnetic mirror to a density of 1012 cm-3 when insulating end plugs were used. The density was slightly reduced if the mirror ratio was reduced to unity and was reduced to 1011 cm-3 if the end plugs were made conducting thus shorting the electric field. The temperature of the trapped plasma corresponded to approximately two thirds of the energy in the initial motion of the beam. These results are discussed qualitatively in terms of the polarization drift model of Schmidt (1960). The possible application of this injection technique to tandem mirrors is discussed briefly.
Virtual Shareholder Meetings (2004)

Electronic communication impacts how widely-held corporations conduct shareholder meetings. For example, technology has facilitated such options as electronic proxy voting, remote electronic voting, and "virtual meetings." This iBrief examines the idea of "virtual meetings" and argues that they should not entirely replace physical meetings unless an electronic solution can be devised which replicates the face-to-face accountability of management to retail shareholders.
Glomerular epithelial and mesangial cells differentially modulate the binding specificities of VLA-1 and VLA-2. (1995)

VLA-1, VLA-2, and VLA-3 are integrin receptors with overlapping specificities in that all have the potential to interact with collagen and laminin. Our studies demonstrate that cultured GEC use VLA-1 and VLA-2 almost exclusively for their adhesion to these ligands, and thus VLA-3 appears to play a negligible role in such attachment. Interestingly, GEC and mesangial cells differentially modulate the ligand binding specificities of VLA-1 and VLA-2. In situ, VLA-1 has been localized within the mesangium, whereas VLA-2 has not been detected within the glomerulus leading to the conclusion that GEC do not use VLA-1 or VLA-2 and that mesangial cells fail to utilize VLA-2. However, our studies have shown that, even when such receptors are barely detectable on the surface of cultured cells by sensitive techniques, they can play a functional role. These results suggest either that the levels of expression in situ are too low for the relatively insensitive immunohistochemical techniques employed, and thus the importance of these receptors to glomerular cell attachment in vivo is under appreciated or that such receptors are the result of de novo expression by glomerular cells when they are subjected to in vitro culture conditions. Because it is known that such conditions may mimic pathologic stress, we are presently examining the expression of these receptors by glomerular cells in various disease models.
Analysis of the promoter and cis-acting elements regulating expression of herpes simplex virus type 2 latency-associated transcripts (1995)

In latently infected neurons, herpes simplex virus type 2 (HSV-2) expresses one abundant family of transcripts, the latency-associated transcripts (LATs). We demonstrate here that the sequence lying about 700 bp upstream of the 5' end of the HSV-2 major LAT acts as a very strong promoter in transient expression assays in both neuronal and nonneuronal cells. Transcription starts about 27 to 32 bp downstream of a functional TATA box. The proximal fragment from -102 to +34 includes the basal promoter and accounts for constitutive transcriptional activity in various cell lines. The distal region from -392 to -103 contributes to particularly strong promoter activity in neuronal cell lines and involves multiple cis-acting elements. A functional activating transcription factor/cyclic AMP (cAMP) response element binding protein motif lies just upstream of the TATA. By DNase I footprint and methylation protection assays, we identified several additional protein-binding sites upstream of the activating transcription factor/cAMP response element binding protein motif. A GC-rich element, termed LAT-3, was located between bases -128 to -102. A 2-bp substitution in LAT-3 markedly reduced promoter activity and abolished protein-binding ability in vitro. Gel retardation assay showed no competition for protein binding to LAT-3 by other GC-rich elements. LAT-3 appears to be a novel cis-acting element that may contribute to the neuronal responsiveness of the HSV-2 LAT promoter.
Emulation and inversion of polarization-mode dispersion (2003)

When a fiber is characterized by measured polarization mode dispersion (PMD) vector data, inversion of these data is required to determine the frequency dependence of the fiber's Jones matrix and, thereby, its pulse response. This tutorial reviews the principal concepts and theory employed in approaches to PMD inversion and in the closely related emulation of PMD. We discuss three second-order emulator models and the distinction between the PMD vectors and the eigenvectors of the fiber's Jones matrix. We extend emulation and inversion to fourth-order and sixth-order PMD using higher order concatenation rules, rotations of higher power designating higher rates of acceleration with frequency, and representation of these rotations by Stokes' vectors.
Alkali Metal Vapors: Laser Spectroscopy And Applications (1980)

This overview addresses the rapidly expanding use of lasers for spectroscopic studies of alkali metal vapors. Since the alkali metals (lithium, sodium, potassium, rubidium and cesium) are theoretically simple ("visible hydrogen"), readily ionized, and strongly interacting with laser light, they represent ideal systems for quantitative understanding of microscopic interconversion mechanisms between photon (e.g., solar or laser), chemical, electrical and thermal energy. The possible implications of such understanding for a wide variety of practical applications (sodium lamps, thermionic converters, magnetohydrodynamic devices, new lasers, "lithium waterfall" inertial confinement fusion reactors, etc.) are also discussed.
Besnoitia besnoiti natural infection in a crossbred cow in India (2020)

Besnoitia besnoiti is an obligate intracellular parasite that causesbesnoitiosis in cattle, goats, and equids.Acute besnoitiosis is characterized bypyrexia, enlargement of the lymph nodes, anorexia, ruminal atony, and necrosis of the epidermis. A crossbred Jersey cow was referred for respiratory distress, swollen lymph nodes, patchy dermis, pyrexia, and anorexia. Skin histopathology revealed Besnoitia cysts. The animal was treated with oxytetracycline (10 mg/kg body weight, IV) for a week and with ivermectin (200 μg/kg, SC) once a week for 75 days with supportive therapy. Chronic bovine besnoitiosis was diagnosed, and the author concluded that no therapeutic plan would be successful. This case is unusual because besnoitiosis is not commonly reported in India
Low damping resonant magnetoelectric sensors (2010)

The signal of magnetic sensors based on resonant cantilevers comprised of elastically coupled piezoelectric and magnetostrictive materials increases as the damping decreases. Here, we demonstrate that air damping which normally is suppressed by evacuation can also be substantially reduced by lowering the resonance frequency. We show that a Si-cantilever structured to include a seismic mass features a resonant magnetoelectric coupling coefficient of 1.8 kV/cmOe at 330 Hz in air.
