Funding the vision. The DTA Foundation supports the initiatives of a new age of collaboration. (2004)

Instrument processing is a key part of the office infection control program. Each step in the process must be performed correctly to help ensure patient safety. The instrument processing area must be organized so that contaminated items are not confused with sterilized items, and so that sterilized items do not accidentally become recontaminated. Instruments need to be cleaned completely of visible debris using an ultrasonic cleaner or instrument washer. The cleaned instruments are packaged before sterilization to protect them from recontamination until they are opened for use for the next patient. Processing the packaged instruments through a heat sterilizer (steam, dry heat, or unsaturated chemical vapor) kills any microbes that remain on the instruments. The sterile packages are handled and stored in a manner that preserves the integrity of the packaging material. The use and functioning of the sterilizer is monitored by mechanical, chemical, and biological means, and records are kept to document these evaluations. Sterilization failures are addressed carefully so that patient safety can be maintained.
Experiment K-6-02. Biomedical, biochemical and morphological alterations of muscle and dense, fibrous connective tissues during 14 days of spaceflight (1990)

Findings on the connective tissue response to short-term space flight (12 days) are discussed. Specifically, data regarding the biochemical, biomechanical and morphological characteristics of selected connective tissues (humerus, vertebral body, tendon and skeletal muscle) of growing rats is given. Results are given concerning the humerus cortical bone, the vertebral bone, nutritional effects on bone biomechanical properties, and soft tense fiber connective tissue response.
Absorption and ester cleavage of methyl salicylate by skin of single-pass perfused rabbit ears (1989)

1. Rabbit ears were single-pass perfused with a cell-free medium. Arterial pressure, oxygen consumption, and lactate production increased with flow rate. 2. Methyl salicylate was hydrolysed with an apparent Vmax of 1.5 nmol/min per cm2 surface area, a rate about 25 times greater than after arterial administration. 3. Estimation of the Km was not possible, due to oedema developing at arterial concentrations greater than 100 microM methyl salicylate. 4. The model appears suitable to compare absorption, as well as metabolic rates, of xenobiotics in rabbit skin.
Location-aware mobile transportation information service (2005)

With the rapid development of mobile communications in recent years, mobile devices have ways to access Internet and contact a map service center. The most significant of mobile location based service (LBS) is that its services may vary dependent on different situation, demand, and location of individual users. That is to provide appropriate information and service based on the understanding the users' location and demand. Challenges remain include: how to make users' operation easy; how to change map content according to users' requirements and location changes; how to improve the location accuracy; how to support mobile devices with various screen size or resolution. In this paper, these issues are investigated with the design and implementation of a location-aware mobile service for transportation information. The mobile public transportation information service we developed provide map-based information of the nearest mass rapid transit (MRT) station, the nearest bus stop of the bus route chosen by the user, and the nearest bus stop of the bus route that can take the user to his/her chosen destination
Maintenance Management in a Decentralised Organisation (1989)

Reduction in road funding and changing corporate role of the Roads Corporation (Victoria) is placing greater emphasis on the need for its Plant Branch to apply the most appropriate modern technology and management techniques to ensure the provision of plant and services which are appropriate to the needs of the Branch's clients, and consistent with the objective and policies of the Roads Corporation. This paper examines methodologies currently being adopted for the Plant Branch decentralised workshop organisation which is required to operate as a competitive self funding business within an open market strategy.
Parameterized blind deconvolution of laser radar imagery using an anisoplanatic optical transfer function (2006)

Gated laser radar imaging systems hold unique promise for long-distance remote sensing applications. Short-exposure speckle imagery from wide field-of-view (FOV) systems may be used to jointly estimate maximum likelihood estimates of the remote scene together with the atmospheric seeing condition parameterized by Fried's parameter. Previous research has indicated that employment of the short-exposure optical transfer function (OTF) within the deconvolution algorithm yields slightly pessimistic estimates of Fried's parameter. It was postulated that the short-exposure OTF included excessive high spatial frequency components when applied to wide FOV systems, yielding seeing condition estimates of the imaging scenario that were slightly lower than if the atmospheric conditions admitted an anisoplanatic system imaging model. To better estimate Fried's parameter, an anisoplanatic OTF (AOTF) was developed using a tilt-only phase correlation approximation. This AOTF was used together with the short-exposure OTF within the MAP algorithm, and estimated seeing conditions were compared for both simulated and experimental wide FOV scenarios. It was found that the additional anisoplanatic blur components modeled by the AOTF increased the accuracy of the estimation of Fried's parameter from 5% to within 2% using simulated imagery, and from 8.6% to within 2.9% using experimentally collected image data.
A microscope‐based screening platform for large‐scale functional protein analysis in intact cells (2003)

A modular microscope-based screening platform, with applications in large-scale analysis of protein function in intact cells is described. It includes automated sample preparation, image acquisition, data management and analysis, and the genome-wide automated retrieval of bioinformatic information. The modular nature of the system ensures that it is rapidly adaptable to new biological questions or sets of proteins. Two automated functional assays addressing protein secretion and the integrity of the Golgi complex were developed and tested. This shows the potential of the system in large-scale, cell-based functional proteomic projects.
Measurement of pressure and temperature sensitivities of a Bragg grating imprinted in a highly birefringent side-hole fiber (2003)

The sensing characteristics of a Bragg grating imprinted in a specially developed highly birefringent side-hole fiber were investigated in detail. We showed that such a grating has almost identical sensitivities to temperature for both linearly polarized modes LP01(x) and LP01(y) (approximately 5.9 pm/K) and significantly different sensitivities to hydrostatic pressure (-1.93 pm/MPa for LP01(x) and +5.37 pm/MPa for LP01(y) mode). The sensitivity differences versus mode polarization are so high that this effect can be employed for simultaneous sensing of temperature and pressure by interrogation of the wavelength shifts at LP01(x) and LP01(y) modes. Applying interferometric methods, we also measured the sensitivity of the host side-hole fiber to temperature and hydrostatic pressure for each polarization mode. Our results show that there is good agreement between the normalized sensitivities of the host side-hole fiber and those of the grating for the same polarization modes.
Experimental study on relationship between jet instability and formation of beaded fibers during electrospinning (2005)

Abstract Ultrafine fibers produced by electrospinning often exhibit bead‐on‐string structures, which have generally been considered to be undesirable “by‐products” or defects. Theoretical analysis in the literature predicted three types of instabilities for an electrically driven jet: the axisymmetric Rayleigh instability, the electric field‐induced axisymmetric, and whipping instability. The process of bead formation revealed that the formation of a beaded structure resulted from axisymmetric deformation and flow of the jet. Applied voltage, solution surface tension, and conductivity (or jet charge density carried by the moving jet) were theoretically demonstrated to be important for jet axisymmetric instabilities. Experimental results revealed that these parameters influenced the formation of beaded fibers in the same manner as they did for the axisymmetric instabilities. As a result, the axisymmetric instabilities were considered to be the most likely mechanism of beaded fibers formation during electrospinning. POLYM. ENG.

Run-time code generation as a central system service (2002)

We are building an operating system in which an integral run time code generator constantly strives to improve the quality of already executing code. Our system is based on a platform independent software distribution format twice as dense as Java byte codes that is translated into native code only at the time of loading. This initial translation happens in a single burst and puts compilation speed ahead of code quality, so that program execution can commence immediately. However, the native code generated during loading will usually not be executed for long. Immediately after a program has started running, its code image becomes a candidate for reoptimization. A background process that executes only during otherwise idle processor cycles continuously recompiles parts of the already running system, guided by run time profiling data, and is able to substitute already executing code in situ. This reoptimization encompasses not only user programs, but also many of the system libraries, eventually combining an application program and most of its dynamically loaded extensions and libraries into a single, fully cross optimized, quasi monolithic code image. Our system is thereby able to provide the efficiency of statically optimized software in spite of being extensible at run time.
Carbon Nanomaterials for Next-Generation Interconnects and Passives: Physics, Status, and Prospects (2009)

This paper reviews the current state of research in carbon-based nanomaterials, particularly the one-dimensional (1-D) forms, carbon nanotubes (CNTs) and graphene nanoribbons (GNRs), whose promising electrical, thermal, and mechanical properties make them attractive candidates for next-generation integrated circuit (IC) applications. After summarizing the basic physics of these materials, the state of the art of their interconnect-related fabrication and modeling efforts is reviewed. Both electrical and thermal modeling and performance analysis for various CNT- and GNR-based interconnects are presented and compared with conventional interconnect materials to provide guidelines for their prospective applications. It is shown that single-walled, double-walled, and multiwalled CNTs can provide better performance than that of Cu. However, in order to make GNR interconnects comparable with Cu or CNT interconnects, both intercalation doping and high edge-specularity must be achieved. Thermal analysis of CNTs shows significant advantages in tall vias, indicating their promising application as through-silicon vias in 3-D ICs. In addition to on-chip interconnects, various applications exploiting the low-dimensional properties of these nanomaterials are discussed. These include chip-to-packaging interconnects as well as passive devices for future generations of IC technology. Specifically, the small form factor of CNTs and reduced skin effect in CNT interconnects have significant implications for the design of on-chip capacitors and inductors, respectively.
Purification of Fc gamma receptor from rabbit alveolar macrophages that retains ligand-binding activity. (1980)

The Fc gamma receptor of rabbit alveolar macrophages was purified by affinity chromatography by using rabbit gamma-globulin (Rab gamma G) coupled to Sepharose. Macrophage preparations were efficiently labeled with 125I by using a modified lactoperoxidase method. After incubation of NP-40 cell lysates with Rab gamma G-Sepharose, elution at 4 degrees C with 0.5 N acetic acid containing 1% NP-40 and rapid neutralization allowed recovery of active Fc gamma receptor. Purified Fc gamma receptor retained its ligand-binding activity, since approximately 41 to 72% of labeled material specifically rebound to Rab gamma G-Sepharose. Active receptor also rebound to human IgG- and rat IgG-sepharose. Active Fc gamma receptor did not bind to Sepharose coupled to rabbit Fab, rabbit F(ab)'2 or human F(ab)'2 fragments, nor to Sepharose coupled to chicken IgG. Analysis of Fc gamma receptor by SDS polyacrylamide gels demonstrated a broad peak of radioactivity in the apparent m.w. range of 50,000 to 70,000 in 5.6% acrylamide gels and 35,000 to 55,000 in 9% gels. Labeled receptor with similar structural characteristics and ligand-binding activity was also obtained from highly purified adherent cell populations and from macrophages biosynthetically-labeled with [14C]glucosamine in culture.
The Corner-Reflector Antenna (1940)

A beam antenna called the corner, V, or sphenoidal reflector type is described. This antenna consists essentially of a driven radiator or dipole and a reflector constructed of two flat, conducting sheets, or their electrical equivalent, which meet at an angle forming a corner. The radiator is usually located in the plane bisecting the corner angle. The performance of the antenna is analyzed mathematically. Gain curves are presented, showing the effect of antenna-to-corner spacing, corner angle, and losses. Computed and measured directional patterns are in good agreement. Dimensions and design data for practical corner antennas using grid-type reflectors are included. The corner reflector is particularly suitable for use on the ultra-high frequencies and microwaves where structures 1 or 2 wavelengths in maximum over-all dimensions are practical. It is simple in construction and can be readily built to fold into a compact portable unit. Multiunit corner reflectors for higher gain and a bidirectional type for broadcast use are mentioned. The application of a single corner reflector with two off-center radiators to a radio range beacon or an airport runway localizer is discussed.

WEAR++: 3D model driven camera tracking on board the International Space Station (2011)

We present WEAR++, a wearable augmented reality system consisting of a head mounted display, a camera and an inertial measurement unit. This paper focuses on the visual camera tracking system developed for WEAR++. Using a 3D model of the scene, we first create a map of 3D-2D correspondences in an off line mapping procedure. During on line operation, we match features from a new image to the database, and track the camera pose with an Extended Kalman Filter using the recovered 3D-2D correspondences. By using robust local features (SURF) and a frustum culling algorithm, we demonstrate that we are able to track the pose even for jerky motions and blurry images. Furthermore, we explain how the system was utilised by astronaut Frank De Winne on board the International Space Station for performing maintenance tasks.
Inhibition of Autoimmune Type 1 Diabetes by Gastrointestinal Helminth Infection (2006)

Gastrointestinal nematode infections are prevalent worldwide and are potent inducers of T helper 2 responses with the capacity to modulate the immune response to heterologous antigens. Parasitic helminth infection has even been shown to modulate the immune response associated with autoimmune diseases. Nonobese diabetic (NOD) mice provide a model for studying human autoimmune diabetes; as in humans, the development of diabetes in NOD mice has been linked to the loss of self-tolerance to beta cell autoantigens. Previous studies with the NOD mouse have shown that helminth and bacterial infection appears to inhibit type 1 diabetes by disrupting the pathways leading to the Th1-mediated destruction of insulin-producing beta cells. The aim of our study was to examine whether infection with the gastrointestinal helminths Trichinella spiralis or Heligmosomoides polygyrus could inhibit the development of autoimmune diabetes in NOD mice and to analyze the mechanisms involved in protection and the role of Th2 responses. Protection from diabetes was afforded by helminth infection, appeared to inhibit autoimmune diabetes by disrupting pathways leading to the destruction of beta cells, and was mediated by seemingly independent mechanisms depending on the parasite but which may be to be related to the capacity of the host to mount a Th2 response.
The Prevention of Lung Cancer Induced by a Tobacco‐Specific Carcinogen in Rodents by Green and Black Tea (1999)

A growing body of evidence from studies in laboratory animals indicates that green tea protects against cancer development at various organ sites. We have previously shown that green tea, administered as drinking water, inhibits lung tumor development in A/J mice treated with 4-(methylnitrosamino)-1-(3-pyridyl)-l-butanone (NNK), a potent nicotine-derived lung carcinogen found in tobacco. The inhibitory effect of green tea has been attributed to its major polyphenolic compound, epigallocatechin gallate (EGCG), and, to a lesser extent, to caffeine. We have also demonstrated that while levels of O6-methylguanine, a critical lesion in NNK lung tumorigenesis, were not affected in lung DNA. However, the levels of 8-hydroxydeoxyguanosine (8-OH-dG), a marker of oxidative DNA damage, were significantly suppressed in mice treated with green tea or EGCG. These studies underscore the importance of the antioxidant activity of green tea and EGCG for their inhibitory activity against lung tumorigenesis. Unlike green tea, the effect of black tea on carcinogenesis has been scarcely studied, even though the worldwide production and consumption of black tea far exceeds that of green tea. The oxidation products found in black tea, thearubigins and theaflavins, also possess antioxidant activity, suggesting that black tea may also inhibit NNK-induced lung tumorigenesis. Indeed, bioassays in A/J mice have shown that black tea given as drinking water retarded the development of lung cancer caused by NNK. However, data on the relationship of black tea consumption with the lung cancer risk in humans are limited and inconclusive. There is a need for additional tumor bioassays in animal models to better examine the protective role of black tea against lung cancer. The development of adenocarcinomas and adenosquamous carcinomas in F344 rats upon chronic administration of NNK provides an important and relevant model for lung carcinogenesis in smokers. Thus far, no information was previously available regarding the effects of tea on this model. We conducted a 2-year lifetime bioassay in F344 rats to determine whether black tea and caffeine are protective against lung tumorigenesis induced by NNK. Our studies in both mice and rats have generated important new data that support green and black tea and caffeine as potential preventive agents against lung cancer, suggesting that a closer examination of the roles of tea and caffeine on lung cancer in smokers may be warranted.

Cirrhosis and hepatoma in alcoholics. (1966)

EDITORIAL SYNOPSIS This paper describes the development of hepatoma in cirrhosis of the alcoholic as seen in east London. The incidence was surprisingly high (30 %) (25 of 84 cases) and was noticed especially in those who had given up alcohol before death and had developed a coarse nodular type of cirrhosis.
Diamond tools in metal bonds dispersion-strengthened with nanosized particles for cutting highly reinforced concrete (2010)

The paper describes two bonds dispersion-strengthened with WC and ZrO2 nanoparticles, which are used in the manufacture of diamond tools for cutting reinforced concrete. The pattern of nano-particles distribution in the metal matrix is studied. Physical-mechanical and tribological properties of the bonds have been determined. The use of dispersion-strengthened bonds is demonstrated to ensure a 60% longer tool life without reducing the cutting speed.
