Introduction (1989)

Shortly after the Second World War, Winston Churchill observed that Britain's primary overseas interests lay in three interlocking 'circles': in Europe, in the Empire and in the 'special relationship' across the Atlantic. For over two decades after 1945, successive British governments pursued a foreign policy strategy which sought to preserve their power and influence in all three of these 'circles'. It was assumed — at least until 1968 — that Britain was still a Great Power with global interests and responsibilities, and that it should accordingly seek to maintain a world role in both the military and the economic spheres.
Design of serially concatenated interleaved codes (2002)

A serially concatenated code with interleaver consists of the cascade of an outer encoder, an interleaver permuting the outer codeword bits, and an inner encoder whose input words are the permuted outer codewords. In this paper we derive design guidelines for the outer and inner codes that maximize the interleaver gain and the asymptotic slope of the error probability curves.

Urethral Dysfunction in Female Mice with Estrogen Receptor β Deficiency (2014)

Estrogen has various regulatory functions in the growth, development, and differentiation of the female urogenital system. This study investigated the roles of ERβ in stress urinary incontinence (SUI). Wild-type (ERβ(+/+)) and knockout (ERβ(-/-)) female mice were generated (aged 6-8 weeks, n = 6) and urethral function and protein expression were measured. Leak point pressures (LPP) and maximum urethral closure pressure (MUCP) were assessed in mice under urethane anesthesia. After the measurements, the urethras were removed for proteomic analysis using label-free quantitative proteomics by nano-liquid chromatography-mass spectrometry (LC-MS/MS) analysis. The interaction between these proteins was further analysed using MetaCore. Lastly, Western blot was used to confirm the candidate proteins. Compared with the ERβ(+/+) group, the LPP and MUCP values of the ERβ(-/-) group were significantly decreased. Additionally, we identified 85 differentially expressed proteins in the urethra of ERβ(-/-) female mice; 57 proteins were up-regulated and 28 were down-regulated. The majority of the ERβ knockout-modified proteins were involved in cell-matrix adhesion, metabolism, immune response, signal transduction, nuclear receptor translational regelation, and muscle contraction and development. Western blot confirmed the up-regulation of myosin and collagen in urethra. By contrast, elastin was down-regulated in the ERβ(-/-) mice. This study is the first study to estimate protein expression changes in urethras from ERβ(-/-) female mice. These changes could be related to the molecular mechanism of ERβ in SUI.
Charged droplet formation in sonic spray (1998)

The reasons why sonic spray ionization can readily produce multiply-charged ions when a high voltage is applied to the source housing have been investigated by using aerosol techniques. Charged droplets were produced by sonic spray from a trifluoroacetic acid solution in triethylene glycol/ethanol. These droplets were analyzed with a differential mobility analyzer to obtain their mobilities, and also analyzed with an aerodynamic particle size spectrometer to obtain their diameters. By combining these results, the charge numbers of the droplets have been determined. The results show that some droplets have charge numbers close to the Rayleigh limit and that the abundance of these droplets increases as the voltage applied to the source housing increases. A qualitative explanation is given for the formation of multiply-charged ions.
Stability of Streptococcus mutatis and Its Relationship to Caries in a Child Population over 2 Years (1983)

The natural history of Streptococcus mutans was studied in occlusal fissures of 238 right and 235 left lower mandibular first molars in 279 children, initially aged 6–7, over a 2-year period. S. mutans infection was endemic in this group. Results showed that the levels of S. mutans were fairly stable – an initially high level of infection tended to stay high, and vice versa. High levels of infection were more associated with subsequent development of caries. None of the 21 teeth with nondetectable levels of S. mutans developed caries, though a number of teeth with high levels of S. mutans remained sound. S. sanguis appeared to have no independent influence on whether caries developed or not.
Load/Unload technology for disk drives (1999)

Load/Unload (L/UL) is an alternative to contact start-stop (CSS) technology which eliminates stiction and wear failure modes associated with CSS. Other benefits of L/UL include increased areal density due to smooth disk surfaces, thinner overcoats and lower head flying height; improved shock resistance due to elimination of head slap; and reduced power consumption. Several mechanical design options exist for L/UL, and tolerance analysis plays a key role in height budgeting, interdisk spacing, and disk real estate usage. To prevent stiction failures arising from unintended landing of heads on stopped disks, a reliable actuator latch and power-off retract system are employed. A bidirectional inertia latch has better reliability than conventional inertia latch designs. A low voltage drop retract rectifier is required for reliable power-off retract in drives with supply voltages of 5 V or less.
Metabolic phenotypes and colorectal neoplasia (1991)

It now appears likely that the development of colonic adenomas and carcinomas involves a series of steps in which environmental or endogenous carcinogens induce or promote neoplasia through the accumulation of multiple, specific genetic mutations. Genetic predisposition to this process may take the form of inherited defects in control of cellular proliferation as in familial polyposis coli, or genetically determined polymorphism which affects enzyme activities relevant to the production or detoxication of carcinogens. Genetic effects may also influence levels of hormones and/or their target cell receptors which regulate the metabolic and proliferative activity of colonocytes. This review highlights data suggesting a role for polymorphism associated with xenobiotic acetylation, hydroxylation, and conjugation with glutathione in the metabolism of potential carcinogens, as well as for dehydroepiandrosterone in the metabolic control of cell proliferation. The study of genetically determined polymorphism in colorectal cancer may provide new insights into the epidemiology of cancer and result in new methods for the detection of higher risk groups.
Photo-Induced Crawling Motion of Azobenzene Crystals on Modified Gold Surfaces (2021)

Photo-induced crawling motion of a crystal of 3,3'-dimethylazobenzene (DMAB) on gold surfaces having different surface properties and various patterns was studied. DMAB crystals crawl continuously when exposed to UV and visible lights simultaneously from different directions. On a gold surface functionalized by a thiol having a hydroxyl group at the terminal (16-hydroxy-1-hexadecanethiol (HOC<sub>16</sub>SH)), the crystals crawled with a relatively high velocity (ca. 4 μm min<sup>-1</sup>), and they changed the crystal shape while keeping a distinct crystal face. On a gold surface functionalized by a thiol having an alkyl chain terminal (1-hexadecanethiol (C<sub>16</sub>SH)), the crawling was observed with a slower velocity (ca. 1.5 μm min<sup>-1</sup>). However, the shape of the crystals became a droplet-like shape soon after the irradiation started, and the shape persisted during the motion. Light intensity dependence of the crawling velocity of the droplet-like crystal on this surface showed that UV light has stronger dependence for the motion than the visible light. On a substrate with a stripe pattern of alternating C<sub>16</sub>SH-modified gold and hexadecyltrimethylsilane (HDTMS)-modified glass, crystals crawled only on the surface of the C<sub>16</sub>SH-modified gold, which may be due to the wettability hysteresis at the surface. On a substrate with a stripe pattern of HOC<sub>16</sub>SH-modified gold and HDTMS-modified glass, crystals were attracted to the gold side. On a gold substrate with a periodic pattern of different height (ca. 50 nm) but having a uniform treatment with C<sub>16</sub>SH, crystals crawled up and down the steps without significant disturbance at the boundary of the step. Therefore, wettability of the surface has a greater impact on controlling the motion of the crystal than the surface structure. The present results not only unveil the crawling behavior on various surfaces but also offer a guide to controlling the motion toward applications for novel carriage vehicles to transport molecules/objects on a surface.
Magnetron sputtering of transparent conductive zinc oxide: relation between the sputtering parameters and the electronic properties (2000)

Magnetron sputtering of transparent conductive oxides (zinc oxide, indium tin oxide, tin oxide) is a promising technique which allows the deposition of films at low temperatures with good optical and electronic properties. A special advantage is the scalability to large areas. The principles underlying magnetron sputtering are reviewed in this paper. The growth process during magnetron sputtering is characterized by the bombardment of the growing film with species from the sputtering target and from the plasma. In addition to sputtered atoms with energies in the eV range, ions from the plasma (mostly argon) and neutral atoms (also argon) reflected at the target hit the growing film. Depending on the energy of these species and on the ion-to-neutral ratio the properties of the films vary. High energies ( 100 eV), which occur mainly at low sputtering pressures lead to damage of the growing film, connected with mechanical stress, small crystallites and bad electrical parameters. Ion assisted growth with low ion energies (below about 50 eV) is advantageous as is a high ion-to-neutral ratio. A compilation of resistivities of magnetron sputtered zinc oxide films yields a limiting resistivity of 2 × 10-4 cm for polycrystalline films. Based on the correlation between plasma parameters and film properties new research fields are anticipated.
Closed loop control of automotive engines. Final report Feb 1978-Jun 1980 (1981)

Internal combustion engine economy and emissions are known to be sensitive to changes in engine control variables. Two of the most important variables are fuel/air ratio (F/A) and spark advance. These variables are affected by environmental changes, manufacturing tolerances, and time degradation. The combined effect of all these changes can cause as much as a 15% loss in economy and a 30% increase in emissions. This research concerns the application of optimization theory to develop control laws for use in closed loop control strategies to minimize the effect of the variables discussed above. The report describes the automated dynamometer facility developed for the acquisition of engine mapping data. This data was used to develop analytical functions describing the fuel consumption and emissions at each of 10 torque/RPM points. The functions were used by an optimization procedure to arrive at control strategies and driving cycle predictions of fuel consumption and emissions. The optimum schedules were then used to determine a closed-loop control strategy.
CHARACTERIZATION AND ADAPTIVE TEXTURE SYNTHESIS-BASED COMPRESSION SCHEME (2011)

This paper presents an adaptive texture synthesis-based compression scheme, where textured regions are detected and removed at encoder side, allowing the decoder to use texture synthesis to fill them. The detection relies on locally adaptive resolution segmentation. According to results shown by synthesis algorithms, they need to be parameterized according to the patterns to be synthesized. In this framework, the synthesizer gets its parameters from DCT feature-based texture descriptors. An adaptive pixel-based algorithm is used, relying on the comparison between current pixel neighborhood and those in an atypically shaped sample. Different neighborhood sizes are considered to better catch texture patterns. The framework has been validated within an H.264/AVC video codec. Experimental results show significant bit-rate saving at similar visual quality. 1.
Smart Bionic Surfaces with Switchable Wettability and Applications (2021)

In order to satisfy the needs of different applications and more complex intelligent devices, smart control of surface wettability will be necessary and desirable, which gradually become a hot spot and focus in the field of interface wetting. Herein, we review interfacial wetting states related to switchable wettability on superwettable materials, including several classical wetting models and liquid adhesive behaviors based on the surface of natural creatures with special wettability. This review mainly focuses on the recent developments of the smart surfaces with switchable wettability and the corresponding regulatory mechanisms under external stimuli, which is mainly governed by the transformation of surface chemical composition and geometrical structures. Among that, various external stimuli such as physical stimulation (temperature, light, electric, magnetic, mechanical stress), chemical stimulation (pH, ion, solvent) and dual or multi-triggered stimulation have been sought out to realize the regulation of surface wettability. Moreover, we also summarize the applications of smart surfaces in different fields, such as oil/water separation, programmable transportation, anti-biofouling, detection and delivery, smart soft robotic <i>etc.</i> Furthermore, current limitations and future perspective in the development of smart wetting surfaces are also given. This review aims to offer deep insights into the recent developments and responsive mechanisms in smart biomimetic surfaces with switchable wettability under external various stimuli, so as to provide a guidance for the design of smart surfaces and expand the scope of both fundamental research and practical applications.

Abstract 17675: The Relationship of Endothelial Shear Stress after Stent Implantation with In-Stent Neointimal Hyperplasia and Clinical Outcomes in Humans (2014)

Background: Neointimal in-stent hyperplasia (ISH) is a frequent complication of percutaneous coronary interventions (PCI), and ultimately may lead to in-stent restenosis (ISR). ISH may develop in regions of low endothelial shear stress (ESS) within the stent, but the relationship between ESS magnitude, the extent of ISH and subsequent clinical events has not been investigated. In patients with an acute coronary syndrome treated with PCI, we assessed the impact of post-PCI ESS on the ISH and ISR requiring repeat PCI. Methods: We investigated the PREDICTION Study database with focus on stents. 3D coronary reconstruction by angiography & intravascular ultrasound was performed in 374 patients after stent implantation (baseline, BL) and at 6-10 month follow-up (FU). Each stent was divided into 1.5mm-long segments, within which we calculated ESS at BL with computational fluid dynamics. At FU, we assessed percent ISH (ISH area/stent area) and the occurrence of a clinically indicated PCI in the same locations. Re...

A model for estimating distributions of fish school target strengths (1978)

A model has been developed to estimate the distribution of fish school target strengths for any schooling species. The model has both biological and acoustic components. The biological component estimates distributions of school size and density for a given species. A discrete spectrum of nondimensionalized school densitites, developed by combining and synthesizing the results of experimental studies on intraschool spacing, is utilized to estimate school density distributions. Discrete spectra of school sizes based on empirical knowledge and assumptions of school growth and reduction are utilized to estimate school size distributions. The acoustic component combines estimates of target strengths of individual fish with numbers of fish insonified to calculate school target strengths at any aspect for a school of given size and density. Multiple scattering is neglected, but attenuation through the school is accounted for by the use of shadowing factors. Provision is made for schools which are not totally insonified due to limitations of sonar beamwidth or pulse length. Comparison to available experimental data indicates that the model produces a reasonable estimate of target strength distributions.
Monitoring Subsurface Barrier Integrity Using Perfluorocarbon Tracers (1998)

Subsurface barriers are an extremely promising remediation option to many waste-management problems. It is recognized that monitoring of the barrier is necessary to provide confidence in the ability of the barrier to contain the pollutants. However, the large size and deep placement of subsurface barriers make detection of leaks a challenging task. Therefore, typical geophysical methods are not suitable for the monitoring of an emplaced barrier's integrity. Perfluorocarbon tracers (PFTs) have been tested as a means of barrier verification at the Hanford geotechnical test facility, where a soil/cement barrier was emplaced around a buried drum. PFTs were injected beneath the drum for three days in the center of the barrier 3 m below grade. The concentration of PFTs in seven external and two internal monitoring wells has been measured as a function of time over a 17-day period. The data have been analyzed through numerical modeling to determine barrier integrity and PFT diffusion rates through the barrier. This paper discusses the experimental design, test results, data analysis, and modeling of PFT transport in the subsurface system.

Manufacture of SiC/ZrSi 2 Composite Materials: Assessing Thermal Compatibility Between Matrix and Reinforcement (2017)

This chapter discusses how SiC-ZrSi2 composites were fabricated by reactive melt infiltration of Si-Zr alloys into porous C/SiC preforms in an experiment. The resulting materials were SiC/ZrSi2 composites, in which remaining silicon was considerably reduced by formation of ZrSi2. The composite materials obtained showed an excellent thermal compatibility between matrix and reinforcement and no evidence of phase de-bonding due to a thermal expansion mismatch. They also exhibit excellent thermal properties with low coefficient of thermal expansion, which makes them ideal candidates for structural high temperature applications. The possibility of combining both Zr-Si alloys and SiC could enlarge the spectrum of applications for such composite materials in nuclear applications and improve the thermal efficiency of the reactor. It is possible to obtain dense, near-net shape SiC/ZrSi2 composites by modifying the classical reactive melt infiltration technique, and carrying it out with a proper ZrSi alloy instead of with pure Si.
Treatment of Wilson's Disease With Ammonium Tetrathiomolybdate (1994)

Tetrathiomolybdate appears to be an excellent form of initial treatment in patients with Wilson's disease presenting with neurologic signs and symptoms. In contrast to penicillamine therapy, initial treatment with tetrathiomolybdate does not result in further, often irreversible neurologic deterioration.

Biodegradation of selected hydrocarbons by novel bacterial strains isolated from contaminated Arabian Gulf sediment (2020)

Three strains of novel bacteria were isolated from oil-contaminated sediment from the Arabian Gulf (Brevibacillus brevis T2C2008, Proteus mirabilis T2A12001, and Rhodococcus quinshengi TA13008). The isolated strains were tested for their degrading efficacy of low and high molecular hydrocarbon (naphthalene and pyrene). The efficacy of the two-hydrocarbon degradation by the isolates bacterial was determined at a temperature of 25 °C and 37 °C and pH of 5.0 and 9.0. In inoculated media at 37 °C, Rhodococcus qinshengi fully metabolized naphthalene and degrade 56% of pyrene. Brevibacillus brevis break down over 80% of naphthalene at room temperatures (25 °C). However, it was found that P. mirabilis and R. qinshengi biodegraded nearly 94% of naphthalene in the incubated media. The capacity for pyrene and naphthalene degradation in varying pH and temperature conditions was shown to be significant in Rhodococcus qinshengi because of its mineralization exceeding 50% across the tested pH and temperature. This implies that the isolated strains are ideal for biodegradation of contaminated sediment with naphthalene and pyrene.
