Processing, presentation, and data basing of acoustic imagery (2002)

The Naval Oceanographic Office (NAVOCEANO) collects and processes acoustic imagery from multiple sensors at various frequencies. These currently include the towed 12-kHz SEAMAP system, the towed 100-kHz hydrographic sidescan, and the hull-mounted multibeam bathymetric sonars. The hull-mounted systems at NAVOCEANO providing acoustic imagery include the 12-kHz Sonar Array Survey System (SASS) and coming on-line in the near future, the 12-kHz SIMRAD 121A. Three issues arise when dealing with multiple imaging sensors: data processing, data volume (data basing), and data presentation and visualization for analysis. To meet the need, NAVOCEANO has developed a generic image processing system, the UNIfied Sonar Image Processing System (UNISIPS) for processing acoustic imagery from various systems. This system includes signal processing, image processing, and georeferencing (digital mosaicing) of the acoustic imagery. Once processed by UNISIPS, these data are entered into a large Geographic Information System (GIS), the Comprehensive Environmental Assessment System (CEAS), where they are integrated with other co-registered data sets for presentation and interpretation. Within CEAS the capability to overlay other data types includes bathymetry, geology, gravity, and altimetry for analysis. The presentation/display/visualization is performed in both two and three dimensions. Presented within the paper are the techniques used for data basing, processing, and data presentation.

Keeping information safe from social networking apps (2012)

The ability of third-party applications to aggregate and re-purpose personal data is a fundamental privacy weakness in today's social networking platforms. Prior work has proposed sandboxing in a hosted cloud infrastructure to prevent leakage of user information [22]. In this paper, we extend simple sandboxing to allow sharing of information among friends in a social network, and to help application developers securely aggregate user data according to differential privacy properties. Enabling these two key features requires preventing, among other subtleties, a new "Kevin Bacon" attack aimed at aggregating private data through a social network graph. We describe the significant architectural and security implications for the application framework in the Web (JavaScript) application, backend cloud, and user data handling.
Advancements in SQL/XML (2004)

Since we last wrote about SQL/XML in [2], the first edition of that new part of the SQL standard has been officially published as an international standard [1], commonly called SQL/XML:2003. At the time of that earlier column, SQL/XML was just entering its first official ballot, meaning that (possibly significant) changes to the text were expected in response to ballot comments submitted by the various participants in the SQL standardization process.
Total Quality Management and Geriatric Care (1998)

Abstract. For numerous reasons it is essential that geriatric practitioners become involved in improving the care delivered to older patients in all clinical settings. One of the more promising approaches to enhancing care for older persons is the set of techniques and philosophy embodied in the Total Quality Management (TQM) method. To develop an agenda for improving the quality of care delivered to older persons, we surveyed over 1,600 geriatric practitioners and asked 38 experts in geriatric care and quality improvement (QI) to respond to a series of questionnaires. Findings resulted in suggested approaches to improving care in four delivery sites (office, home, acute hospital nursing home). Of note, the experts strongly favoured the newer QI methods such as TQM over traditional approaches such as Medicare Review and Minimum Data Set. Potential next steps to improve QI methods in geriatric care are outlined, use of TQM in office practice and nursing homes is reviewed, and examples of successful TQM programs in these settings are described.
Iron‐Catalyzed <i>N</i>‐Arylations of Amides (2008)

Iron can do it too! A novel, experimentally simple procedure for the N-arylation of primary amides with aryl iodides involving an in situ formed iron-based catalyst is reported. The success of the reaction relies on the use of cheap and environmentally friendly FeCl3 in combination with an inexpensive diamine ligand as catalyst system (see scheme).

CyberWalk (2011)

Despite many recent developments in virtual reality, an effective locomotion interface which allows for normal walking through large virtual environments was until recently still lacking. Here, we describe the new CyberWalk omnidirectional treadmill system, which makes it possible for users to walk endlessly in any direction, while never leaving the confines of the limited walking surface. The treadmill system improves on previous designs, both in its mechanical features and in the control system employed to keep users close to the center of the treadmill. As a result, users are able to start walking, vary their walking speed and direction, and stop walking as they would on a normal, stationary surface. The treadmill system was validated in two experiments, in which both the walking behavior and the performance in a basic spatial updating task were compared to that during normal overground walking. The results suggest that walking on the CyberWalk treadmill is very close to normal walking, especially after some initial familiarization. Moreover, we did not find a detrimental effect of treadmill walking in the spatial updating task. The CyberWalk system constitutes a significant step forward to bringing the real world into the laboratory or workplace.
Handbook of Nucleic Acid Purification (2009)

An Indispensable Roadmap for Nucleic Acid Preparation Although Friedrich Miescher described the first isolation of nucleic acid in 1869, it was not until 1953 that James Watson and Francis Crick successfully deciphered the structural basis of DNA duplex. Needless to say, in the years since, enormous advances have been made in the study of nucleic a
Homomorphic public-key cryptosystems over groups and rings (2003)

We propose a new homomorphic public-key cryptosystem over arbitrary nonidentity finite group based on the difficulty of the membership problem for groups of integer matrices. Besides, a homomorphic cryptosystem is designed for the first time over finite commutative rings.
Epstein-Barr virus infection in peripheral blood mononuclear cells, synovial fluid cells, and synovial membranes of patients with rheumatoid arthritis. (2000)

These findings support the hypothesis that EBV infection may be involved in the pathogenesis of RA. Further studies may define the precise pathogenetic mechanisms of viral infection for the development of inflammatory arthritis.
What Can Be Measured from Surface Electrogastrography (1997)

The aims of this study were to investigate the detectability of the propagation of the gastric slow wave from the cutaneous electrogastrogram (EGG) and the patterns of the EGG when the gastric slow waves are uncoupled. A mathematical model was established based on the volume conductor theory to simulate the transfer of the serosal gastric slow wave from the stomach to the abdominal surface. A number of computer simulations were conducted using the model, and the periodic cross-correlation function was used to estimate the phase shift between the four channels. It was found that the propagation of the gastric slow wave was detectable from the multichannel EGG signals. The detectability of the propagation was, however, associated with a number of factors, such as the thickness of the abdominal wall and the propagation velocity of the serosal slow wave. The amplitude of the EGG was found to be associated with the coupling/uncoupling and propagation velocity of the gastric slow wave. The amplitude of the EGG increased when the propagation velocity of the gastric slow wave increased. The amplitude of the EGG was substantially decreased when the gastric slow waves were uncoupled. The uncoupling of the gastric slow wave at a frequency of 3 cpm produced dysrhythmias in the EGG, including tachygastria, bradygastria, and arrhythmia. The power spectra of simulated different positional EGG signals showed similar patterns when the gastric slow wave was coupled and different and unpredictable patterns when the gastric slow wave was uncoupled. In conclusion, multichannel EGG recordings may be necessary to obtain more information on gastric slow waves from the abdominal electrodes. The propagation and coupling or uncoupling of the gastric slow wave may be detected from multichannel EGG recordings.
DOT: A Spatial Access Method Using Fractals (2018)

Existing Database Management Systems (DBMSs) do not handle efficiently multi-dimensional data such as boxes, polygons, or even points in a multi-dimensional space. We examine access methods for these data with two design goals in mind: (a) efficiency in terms of search speed and space overhead and (b) ability to be integrated in a DBMS easily. We propose a method to map multidimensional objects into points in a 1- dimensional space; thus, traditional primary-key access methods can be applied, with very few extensions on the part of the DBMS. We propose such mappings based on fractals; we implemented the whole method on top of a B+-tree, along with several mappings. Simulation experiments on several distributions of the input data show that a modified Hilbert curve gives the best results, even when compared to R-trees [7].
Porous Gelatin Membranes Obtained from Pickering Emulsions Stabilized with h-BNNS: Application for Polyelectrolyte-Enhanced Ultrafiltration (2020)

In recent years, numerous studies have been conducted to develop biopolymer-based membranes, highlighting the challenges to prepare porous structures with control porosity. In this paper an innovative method that relies on the generation of Pickering emulsions was developed to prepare porous membranes from gelatin for filtration purpose. Hexagonal boron nitride nanosheets (h-BNNS) were used to stabilize micro-droplets of castor oil in a continuous homogeneous gelatin solution. Two steps in the membrane preparation process strongly influenced the porous structure. Specifically, the duration of the drying time after emulsion casting and the duration of the cross-linking step affected membrane pore size, hydrophobicity, water swelling, and water permeability. By controlling these two steps, membranes could be designed with pore size between 0.39 and 1.60 μm and display pure water permeability between 150 and 506 L h<sup>-1</sup> m<sup>-2</sup> bar<sup>-1</sup>. These membranes have been tested for complexation-ultrafiltration experiments in which iron ions were removed from aqueous solutions with/without poly (acrylic acid) (PAA). Without PAA, the removal of free iron (II) ions was low (not more than 14%). The addition of PAA (200 ppm) allowed obtaining high removal rates (97%) at pH ≥ 5 with 3 bars of transmembrane pressure.
Discovery of Some of the Biological Effects of Nitric Oxide and Its Role in Cell Signaling (Nobel Lecture) (1999)

A unique simple molecule with an array of signaling functions: NO. The free radical nitric oxide not only mediates a long list of biological effects by activating guanylyl cyclase and increasing cyclic GMP synthesis from GTP, but can also interact with transition metals such as iron, thiol groups, other free radicals, oxygen, superoxide anion, unsaturated fatty acids, and other molecules. Furthermore, NO can function as an intracellular messenger, an autacoid, a paracrine substance, a neurotransmitter, or a hormone that can be carried to distant sites for effects.
Amelioration of experimental metabolic syndrome induced in rats by orlistat and <i>Corchorus olitorius</i> leaf extract; role of adipo/cytokines (2018)

Corchorus olitorius is effective as orlistat in preventing obesity, hyperlipidaemia, steatosis and insulin resistance. These actions may be mediated by inhibiting of lipase activity, TNF-α, IL-1β and leptin resistance along with increasing of adiponectin.
Multi-walled carbon nanotubes synthesised from different catalysts: morphology, dielectrophoresis and conductance (2009)

We give a brief overview of research to date on carbon nanotubes in New Zealand. We then present an investigation of the relationship between morphology and conductance and other properties of multi-walled carbon nanotubes (MWCNTs) synthesised under identical conditions using different catalyst precursors, namely ferrocene and iron (II) phthalocyanine. Large differences were observed in the morphology, the composition, the thermal stability with respect to oxidation and the Raman spectra of the MWCNTs from the two precursors. We focus on the assembly of MWCNTs in an AC electric field (dielectrophoresis). The AC response of the field-collected MWCNTs indicated that both sorts of MWCNT showed high polarisability, but surprisingly, only the more disordered MWCNTs grown from ferrocene-derived catalyst formed conducting paths between the electrodes. Our results suggest that that the formation of highly-conducting electrical contacts between the ferrocene-derived MWCNTs and electrodes is favoured by their greater Fe content. We suggest that Fe nanoparticles act as 'nanoshorts' between neighbouring MWCNTs and between MWCNTs and electrodes.
An approach for controlling printed line-width in high resolution roll-to-roll gravure printing (2013)

One of the challenges in printed electronics is the capacity to print a high resolution electrode. However, it is difficult to gain control over fidelity of microscale line-width of printed patterns especially in roll-to-roll (R2R) gravure printing process. Here, we report a simple solution based on the wettability of ink on the substrate to prevent a widening effect of printed patterns thereby enhancing the precision. The widening effect was found to be affected by intrinsic (ink wetting behavior, cell geometry) and extrinsic (nip pressure, printing speed) conditions. Analysis was conducted to figure out an effect of surface tension of ink and surface energy of substrate on the printed pattern width via contact angle (θIS). For a given cell volume, the width of printed patterns decreased with increasing contact angle. The experimental method was used to determine the optimal extrinsic condition and unstable region border. Finally, we identified three ink setting regions of widening (θIS ≤ ), un-widening (<θIS <) and unstable region (θIS ≥ ). The experimental data showed a good agreement with expected results based on the established analytical approach. This result could be used as an important practical guideline to be applied in R2R gravure printing process with high resolution.
Syllabification of conversational speech using Bidirectional Long-Short-Term Memory Neural Networks (2011)

Segmentation of speech signals is a crucial task in many types of speech analysis. We present a novel approach at segmentation on a syllable level, using a Bidirectional Long-Short-Term Memory Neural Network. It performs estimation of syllable nucleus positions based on regression of perceptually motivated input features to a smooth target function. Peak selection is performed to attain valid nuclei positions. Performance of the model is evaluated on the levels of both syllables and the vowel segments making up the syllable nuclei. The general applicability of the approach is illustrated by good results for two common databases-Switchboard and TIMIT-for both read and spontaneous speech, and a favourable comparison with other published results.
Tumor Cell Adhesion to Endothelial Cells: Endothelial Leukocyte Adhesion Molecule-1 as an Inducible Adhesive Receptor Specific for Colon Carcinoma Cells (1991)

Activation of endothelial cells by the two inflammatory mediators interleukin-1 (IL-1) and tumor necrosis factor strongly increases tumor cell adhesion. We describe antibody inhibition studies showing that the endothelial leukocyte adhesion molecule-1 (ELAM-1), a cell-surface glycoprotein selectively expressed by cytokine-activated endothelial cells and responsible for neutrophil adhesion, is the major, if not the only, mediator of colon carcinoma cell adhesion to activated endothelial cells. Among the different tumor cell lines tested, seven colon carcinoma cell lines were sensitive to ELAM-1 antibodies. Adhesion of melanoma, osteosarcoma, and lung, cervix, or kidney carcinoma cell lines to IL-1-treated endothelial cells was not affected by the ELAM-1 antibody. This result suggests that ELAM-1 is selectively recognized by colon carcinoma cells and that adhesion of tumor cells to activated endothelial cells could be mediated by different and specific mechanisms.
Carbon-Based Electric Double Layer Capacitors for Water Desalination (2010)

In capacitive deionization (CDI), salt water is passed through two polarized electrodes, whereby the salt is adsorbed onto the electrode surface and removed from the water stream. This approach has received renewed interest for water desalination due to the development of new high-surface area carbon-based nanomaterials. However, there is currently limited understanding as to how electrode geometry, surface properties, and capacitance affect ion capture. In this work, we experimentally investigate various standard carbon-based electrode materials, including activated carbon and carbon cloths, as well as microfabricated silicon structures for CDI. Electrochemical characterization through cyclic voltammetry was used to determine the electrochemical properties of each material. In addition, a mini-channel test cell was fabricated to perform parametric studies on ion capture. By controlling electrode geometry and chemistry in these studies, the work helps elucidate transport mechanisms and provide insight into the design of optimal materials for capacitive deionization.
Synthesis of Radiation Curable Palm Oil–Based Epoxy Acrylate: NMR and FTIR Spectroscopic Investigations (2015)

Over the past few decades, there has been an increasing demand for bio-based polymers and resins in industrial applications, due to their potential lower cost and environmental impact compared with petroleum-based counterparts. The present research concerns the synthesis of epoxidized palm oil acrylate (EPOLA) from an epoxidized palm oil product (EPOP) as environmentally friendly material. EPOP was acrylated by acrylic acid via a ring opening reaction. The kinetics of the acrylation reaction were monitored throughout the reaction course and the acid value of the reaction mixture reached 10 mg KOH/g after 16 h, indicating the consumption of the acrylic acid. The obtained epoxy acrylate was investigated intensively by means of FTIR and NMR spectroscopy, and the results revealed that the ring opening reaction was completed successfully with an acrylation yield about 82%. The UV free radical polymerization of EPOLA was carried out using two types of photoinitiators. The radiation curing behavior was determined by following the conversion of the acrylate groups. The cross-linking density and the hardness of the cured EPOLA films were measured to evaluate the effect of the photoinitiator on the solid film characteristics, besides, the thermal and mechanical properties were also evaluated.
Clinical Practice Guideline: Safe Medication Use in the ICU (2017)

This guideline evaluates the ICU environment as a risk for medication-related events and the environmental changes that are possible to improve safe medication use. Prevention strategies for medication-related events are reviewed by medication use process node (prescribing, distribution, administration, monitoring). Detailed considerations to an active surveillance system that includes reporting, identification, and evaluation are discussed. Also, highlighted is the need for future research for safe medication practices that is specific to critically ill patients.
Visible-light plasmonic photocatalyst anchored on titanate nanotubes: a novel nanohybrid with synergistic effects of adsorption and degradation (2012)

A nanohybrid plasmonic photocatalyst, comprising Ag-AgX (X = Cl, Br, I) nanoparticles anchored on titanate nanotubes, was fabricated via a silver ion incorporation process followed by hydrogen halide injection and light-irradiation. The Ag-AgX-titanate nanotubes (Ag-AgX-TNT) hybrid with a high surface area could synergistically adsorb and degrade methylene blue (MB) under visible light, viz., the titanate nanotubes adsorb MB onto their surfaces, which aids the degradation of MB by Ag-AgX nanoparticles. The excellent degradation performance of Ag-AgX under visible light originated from its localized surface plasmonic resonance effect. Therefore, this integrated silver halides/titanate hybrid can efficiently degrade MB dye, and shows good potential for waste water treatment utilizing solar irradiation.
