Molecular Cloning and Characterization of the <i>Helicobacter pylori fliD</i> Gene, an Essential Factor in Flagellar Structure and Motility (1999)

ABSTRACT Helicobacter pylori colonizes the human stomach and can cause gastroduodenal disease. Flagellar motility is regarded as a major factor in the colonizing ability of H. pylori . The functional roles of flagellar structural proteins other than FlaA, FlaB, and FlgE are not well understood. The fliD operon of H. pylori consists of flaG , fliD , and fliS genes, in the order stated, under the control of a ς 28 -dependent promoter. In an effort to elucidate the function of the FliD protein, a hook-associated protein 2 homologue, in flagellar morphogenesis and motility, the fliD gene (2,058 bp) was cloned and isogenic mutants were constructed by disruption of the fliD gene with a kanamycin resistance cassette and electroporation-mediated allelic-exchange mutagenesis. In the fliD mutant, morphologically abnormal flagellar appendages in which very little filament elongation was apparent were observed. The fliD mutant strain was completely nonmotile, indicating that these abnormal flagella were functionally defective. Furthermore, the isogenic fliD mutant of H. pylori SS1, a mouse-adapted strain, was not able to colonize the gastric mucosae of host mice. These results suggest that H. pylori FliD is an essential element in the assembly of the functional flagella that are required for colonization of the gastric mucosa.
Radiographic aids in the management of intraocular foreign body in the chamber angle. (1975)

A technique of bone free radiography for the purpose of diagnosis of a minute intraocular foreign body and for the purpose of confirming the removal of the foreign body under sterile operating room conditions has been described. In addition to the obvious medical advantage of absolutely confirming the removal of an intraocular foreign body there is also the medico-legal benefit of documentation before leaving the operating room.
Mercury levels in New Zealand snapper <i>Chrysophrys auratus</i> (1975)

Abstract The New Zealand snapper Chrysophrys auratus is the object of a major fishery and contributes approximately 30% of the annual landed weight of fin‐fish. Samples of 65 fish from 7 localities on the New Zealand coast were analysed for mercury. Though there is an increase in mercury concentration with size of fish, the larger, older individuals with relatively high mercury levels contribute only a small proportion to the landed catch. Therefore, in establishing the average concentration of mercury in fish, due weight should be accorded to the differences in size composition of the catch. On this basis the average levels of mercury in snapper offered for human consumption are of the order of 0.25 ppm. As this is only half the “permissible safe level” of most other countries where fish consumption is much higher, the risk to the New Zealand consumer is negligible.
Inferring 3D body pose from silhouettes using activity manifold learning (2004)

We aim to infer 3D body pose directly from human silhouettes. Given a visual input (silhouette), the objective is to recover the intrinsic body configuration, recover the viewpoint, reconstruct the input and detect any spatial or temporal outliers. In order to recover intrinsic body configuration (pose) from the visual input (silhouette), we explicitly learn view-based representations of activity manifolds as well as learn mapping functions between such central representations and both the visual input space and the 3D body pose space. The body pose can be recovered in a closed form in two steps by projecting the visual input to the learned representations of the activity manifold, i.e., finding the point on the learned manifold representation corresponding to the visual input, followed by interpolating 3D pose.
Design and Implementation of a Coherent Memory Sub-System for Shared Memory Multiprocessors (2006)

Recent technology advances in integrated electronics offer the ability to ad d more and more transistors into modern chips. Chip Multiprocessors (CMPs) are architectures that feature multiple processing cores on a single chip. They result in highe r processing power, easier design scalability, and greater performance/power ratio. CMPs appear to be one of the dominating architectural approaches for the years to come in the area of high performance architectures. The purpose of this work is to design and implement a shared memory multi-core system that matches the needs of future CMPs. Specifically, an FPGA-bas ed prototype has been implemented, which constitutes a two-node processing system. The design takes advantage of the two PowerPC cores that are embedded in the FPGA fabric. We have implemented external coherent caches equipped with a MESI protocol, and a bus-based coherent memory interconnect to connect the two processors. Shared memory resides in external DDR memory accessible through the interconnect and the DDR controller. We find that the area overhead of our coherent memory system is 33.4% of a mediumsize FPGA. We evaluate the performance of the system by using both simulations and custom software benchmarks running on the two processors. Our simulations show that the system implemented is more efficient than systems based exclusively by Xilinx softcores that offer the same type of memory coherence. Our custom benchmarks simulate basic operations found commonly in parallel programs. Our results show that our design scales well with respect to a single processor, for the Merge-Sort algorithm and the Producer-Consumer benchmark that don”t require a great amount of synchronization traffic. The speedup measured ranges between 1.89 to 1.92 and 1.89 to 3.45, r espectively. On the other hand, the Shared-Counter benchmark slows down by 3 to 10 times due to excessive synchronization traffic.
Building trust in third-party components using component wrappers in the .NET frameworks (2002)

Software purchasers are often provided with very sparse information about how to correctly deploy software components. We describe a novel contract-based approach to building trust in third party components. In contrast to the usual approach where contracts specifying the software semantics are constructed at the time of source code generation, we retrofit existing components with Contract wrappers. Sets of client requirements on the component are expressed in terms of software contracts using the Design by Contract method. The targeted component is then wrapped in this executable specification. Subsequent calls to the component are made via the wrapper. Any client misunderstanding about the component&apos;s functionality will be picked up as contract violations. Contract wrappers also serve as the basis for test suites for integrating components into applications, and as documentation for future updates.

Green Network Planning of Single Frequency Networks (2010)

This paper investigates the network deployment of single frequency networks (SFN) based on OFDM schemes that are standardized for terrestrial broadcasting systems, for digital audio broadcasting (DAB) and for digital video broadcasting (DVB) systems. The concept of green network planning is presented. The term `green' refers to low carbon, energy efficiency and low exposure to radiation, parameters important for the sustainable growth. For the purpose of our investigation a mountainous area of Northern Greece is examined, that is described by a digital terrain elevation model (DTEM) and field computations are based on multi shape slope uniform theory of diffraction (UTD) technique. A genetic algorithm (GA) optimization method is developed for the network planning purposes. A comparison between various planning strategies is presented. It is shown that great CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> reductions, cost savings and low exposure to radiation can be achieved when the network planning considers a `green' strategy.
On the spatial localization of a wireless transmitter from a multisensor receiver (2008)

We consider the fundamental ability of multisensor receiver of finite spatial extent to localize a wireless transmitter in space. Spatial localization is identified with a multisensor receiver's ability to distinguish source transmitters from different regions in space based on imperfect measurements within the finite spatial extent spanned by the receiver's sensors. Two transmitters positioned within a determined spatial region cannot be distinguished or resolved according to a given measurement threshold. The space outside that occupied by the receiver is shown to be tiled by a finite number of such regions. Further, the regions depend on whether intensity information only is used or whether there is both magnitude and phase information available. Numerical examples are given based on a novel tiling algorithm.
Some Properties of Cells Cultured From Early-Lactation Human Milk (1977)

Cells that can be cultured from pools of early-lactation milk were studied. Under the culture conditions used, the majority of cells attached to collagen-coated dishes; most of these remained single, did not divide, and in their adhesiveness, phagocytic ability, and ultrastructure resembled macrophages or histiocytes. On a plate seeded with approximately 3 X 10(5) cells, however, 10-100 colonies of dividing cells developed. These cells had the junctional complexes typical of epithelial cells and grew well in a medium supplemented with human serum and hydrocortisone for 16-20 days after seeding. After removal of serum from the medium, some cells continued to traverse the cell cycle, and the colonies containing these cells were morphologically distinct from those which became quiescent. The nondividing cells in milk could be separated from the milk epithelial cells and were able to stimulate the growth of epithelial cultures from benign mammary dysplasias.
Security Standards-Government and Commercial (1988)

Computer security standards are needed to reduce the cost of security products and to allow for interoperability and evaluation. Several national and international groups are trying to standardize approaches to information security for certain applications. This paper describes and compares three types of standards activities: United States government standards, financial standards, and standards developed for the International Standards Organization Open Systems Interconnection Basic Reference Model.
The immune response of BALB/c mice to influenza hemagglutinin: commonality of the B cell and T cell repertoires and their relevance to antigenic drift (1989)

An extensive analysis of the class II (I-Ad)-restricted T cell repertoire for influenza hemagglutinin (HA) of the H3 subtype, elicited by natural infection, has shown that majority of CD4+ memory T cell clones focus on antibody-binding regions of HA, sites B and E, and are sensitive to the residue substitutions that have occurred in these regions during antigenic drift. The proliferative responses of CD4+ clones to synthetic peptides have identified T cell epitopes within site B, HA1 177-199 and HA1 182-199, and site E. HA1 56-76. The recognition specificity of T cell clones for antibody-selected mutant viruses, with single amino acid substitutions within these recognition sites identified residues 63, 189, 193 and 198 as being important for T cell recognition and thus established that BALB/c, CD4+ T cell clones were sensitive to the same substitutions known to abrogate BALB/c antibody recognition of the native HA. Our findings indicate extensive commonality of the B cell and T cell repertoires for HA, which may be relevant to an understanding of the immune pressures for antigenic drift, and, moreover, suggest that the antigen-specific B memory cell may be instrumental in selection of the peripheral T cell repertoire.
Cortisol Metabolism and Visceral Obesity: Role of 11β‐Hydroxysteroid Dehydrogenase Type I Enzyme and Reduced Co‐factor NADPH (2003)

Several factors including genetic and environmental play a role in the development of obesity and the metabolic syndrome. The transgenic mouse overexpressing 11beta-hydroxysteroid dehydrogenase (11beta-HSD) develops visceral obesity. However, it remains unclear how a ubiquitously expressed 11beta-HSD1 enzyme affects adipose tissue so much that it would lead to obesity. In this commentary we explore the possibility that increased intracellular availability of reduced co-factor, NADPH, could exacerbate the enzymatic activity.
Analysis of oscillators with external feedback loop for improved locking range and noise reduction (1999)

A simple scheme for enhancing the locking/capture range and phase-noise performance of FET-based voltage-controlled oscillators (VCO's) is presented using a low-pass feedback loop from the oscillator output to the varactor tuning port. The nonlinearity of the FET provides for mixer or phase detector behavior (a self-oscillating mixer). The resulting feedback oscillator advantageously combines the principles of a conventional injection-locked oscillator (ILO) and phase-locked loop (PLL), which we refer to as an injection-locked phase-locked loop (ILPLL). The analysis suggests that the ILPLL can be designed for superior near-carrier phase-noise performance compared with conventional ILO or PLL circuits. A 10-GHz prototype was fabricated, which demonstrated a locking range more than double that of the isolated VCO injection-locking range over the same range of injected signal power.
Reflowable Document Images for the Web (2003)

The paper describes on-going work on a system that transforms page-oriented document images into “reflowable document images”, representations of the page image in HTML format that allows it to adapt to display devices of different sizes while preserving the original appearance of the image as much as possible and avoiding OCR errors. The approach to document layout analysis used by the system is outlined and the strengths and limitations of HTML for this application are discussed.
Effect of Mitochondrial Electron Transport Chain Inhibitors on Superoxide Radical Generation in Rat Hippocampal and Striatal Slices (2001)

In this study, we have compared the generation of superoxide radical in rat hippocampal and striatal slices in the presence of specific mitochondrial electron transport chain (ETC) inhibitors (complexes I and III) under control and depolarization conditions [incubation in artificial cerebrospinal fluid (ACSF) or depolarizing ACSF (dACSF), respectively]. Superoxide radical generation was increased in both ACSF- and dACSF-incubated hippocampal and striatal slices when rotenone and antimycin A were added to the incubation medium. The increase in superoxide radical was dependent on the concentration of ETC inhibitors under control, but not depolarization conditions. Rotenone was found to be more effective than antimycin A in producing superoxide radical from hippocampal and striatal slices. Our results also showed that hippocampal slices were more sensitive to ETC inhibitors compared with striatal slices. Thus, different regions of the brain seem to differ in their capacity to generate free radicals and vulnerability to oxidative stress conditions. This difference should be considered in developing therapeutic modalities against oxidative stress-related disorders and neurodegeneration.
Structural analysis of fertilinβ cyclic peptide mimics that are ligands for α<sub>6</sub>β<sub>1</sub> integrin (2002)

The NMR structural analysis of two fertilin(beta) mimics cyclo(EC2DC1)YNH2, 1, and cyclo(D2EC2D1C1)YNH2, 2 is described. Both of these mimics are moderate inhibitors of sperm-egg binding with IC50 values of 500 microm in a mouse in vitro fertilization assay. For peptide 1, the optimized conformations that best match the NMR data have a pseudo-type II' beta-turn with the linker and Glu at the i+1 and i+2 positions, respectively. The EC2D1C1 sequence is in a nonclassical (type IV) beta-turn. For peptide 2, the conformation that best matches the NMR data has two turns: a pseudo-type II' beta-turn in the D2EC2D1 sequence followed by a nonclassical beta-turn in the EC2D1C1 sequence. The Cbeta-Cbeta distance between E and D1 in peptide 1 is 9.1 A, in peptide 2, it is 7.7 A. Thus, one possibility for the high IC50 values of these cyclic peptides is that the acidic residues are not constrained to a sufficiently tight turn, and thus much entropy must still be lost upon binding to the alpha6beta1 integrin. This explains why the cyclic peptides are the same as linear peptides at inhibiting sperm-egg binding.
The partial synthesis of ergosta-5,7,22,24(28)-tetraen-3β-ol (1970)

The Diels–Alder adduct between ergosterol acetate and 4-phenyl-1,2,4-triazolin-3,5-dione can be efficiently re-converted into ergosterol by lithium aluminium hydride reduction; using this reaction as a key step, ergosta-5,7,22,24(28)-tetraen-3β-ol has been synthesised in labelled form and shown to be an efficient precursor of ergosterol in yeast.
Two iridovirus isolates from <i>Carassius auratus</i> (L.) (1983)

Abstract. Two new viruses, goldfish virus‐1 (GFV‐1) and goldfish virus‐2 (GFV‐2), were isolated from swimbladder cultures prepared from healthy Carassius auratus (L.). The isolates were sensitive to pH, heat, and chloroform but stable to freezing and thawing. Treatment with IUDR, Feulgen staining and acridine orange staining indicated that the viruses contain double‐stranded DNA. Electron microscopy revealed enveloped virions of 180 nm enclosing icosahedral capsids of 120 nm. Viral growth was studied by light and electron microscopy and infectivity assays. Virions were assembled in cytoplasmic inclusion bodies and apparently released through cell degeneration. Infectious virus was first produced at 24 h post‐infection. Progressive cytopathology was observed leading to cell ghosts by 96 h post‐infection. The results suggest tentative placement of the viruses in the family Iridoviridae.
Compact full-motion video hyperspectral cameras: development, image processing, and applications (2015)

Emergence of spectral pixel-level color filters has enabled development of hyper-spectral Full Motion Video (FMV) sensors operating in visible (EO) and infrared (IR) wavelengths. The new class of hyper-spectral cameras opens broad possibilities of its utilization for military and industry purposes. Indeed, such cameras are able to classify materials as well as detect and track spectral signatures continuously in real time while simultaneously providing an operator the benefit of enhanced-discrimination-color video. Supporting these extensive capabilities requires significant computational processing of the collected spectral data. In general, two processing streams are envisioned for mosaic array cameras. The first is spectral computation that provides essential spectral content analysis e.g. detection or classification. The second is presentation of the video to an operator that can offer the best display of the content depending on the performed task e.g. providing spatial resolution enhancement or color coding of the spectral analysis. These processing streams can be executed in parallel or they can utilize each other’s results. The spectral analysis algorithms have been developed extensively, however demosaicking of more than three equally-sampled spectral bands has been explored scarcely. We present unique approach to demosaicking based on multi-band super-resolution and show the trade-off between spatial resolution and spectral content. Using imagery collected with developed 9-band SWIR camera we demonstrate several of its concepts of operation including detection and tracking. We also compare the demosaicking results to the results of multi-frame super-resolution as well as to the combined multi-frame and multiband processing.
