Hydrocracking of Athabasca bitumen: effect of coal-base catalyst on pilot plant operation (1977)

In this study, pilot plant experiments are described in which a coal-base catalyst, consisting of a "coke getter" (high volatile A coal) coated with a desulphurization catalyst (Co-Mo-alumina, 15 wt % of the coal), was used in the hydrocracking of Athabasca bitumen. The slurry of bitumen and 2% coal-base catalyst was pumped into the bottom of a 4.5-9, reactor (3.8 cm dia and 4 m long) at 460°C and 13.89 MPa pressure. Pilot plant operation was smooth with a system pressure drop of less than 0.4 MPa. After 21 days of operation, the hot separator, preheaters and all transfer lines were clean but the reactor contained a hard porous deposit along 3 m of its length. Although hydrogen consumption in this run was higher than for a similar run without catalyst, there was more coke deposition. The probable cause of increased reactor coking was the low melting point of the coal which resulted in high ash content in the reactor fluid. Sulphur removal was higher than for a run under similar conditions without additive. There were no problems with the additional hydrogen sulphide gas in the system.
Partial purification of a specific antigen of Treponema hyodysenteriae (1979)

A specific antigen of pathogenic Treponema hyodysenteriae was extracted from lyophilized cells of isolant B169 with hot phenol-water, isolated, and semipurified by starch block electrophoresis.
High field localized proton spectroscopy in small volumes: greatly improved localization and shimming using shielded strong gradients (1989)

The availability of shielded gradients facilitates accurate single-voxel spectroscopy. Exact localization (90-99%) of volumes as small as 2 x 2 x 2 mm is demonstrated using a modified stimulated echo sequence. Strong gradient pulses (up to 200 mT/m) are employed to clear the stimulated echo of unwanted magnetization, enabling superior (single-scan) shimming of the selected volume. In vivo and in vitro proton NMR results at 4.7 T are presented.
Mass spectrometric identification of anN-oxide formed by incubation ofN,N-dimethyl-5H-dibenzo[a,d]cycloheptene-Δ5,γ-propylamine with rat liver microsomes (1974)

On incubation with rat liver microsomes, N,N-dimethyl-5H-dibenzo[a,d]cycloheptene-Δ5,γ-propylamine is converted to the N-oxide. The identification of this metabolite has been achieved by the use of gas chromatography, mass spectrometry and thin-layer chromatography.
Metamorphic photonic network systems based on autonomous wavelength management (2007)

We propose a metamorphic photonic network system that enables session-based, IP flow aware dynamic optical resource allocation, based on autonomous wavelength management. A superdense WDM scheme that offers a minimal channel spacing of 0.1 nm is used as a flexible extension of conventional WDM channels. Here we propose to use smart devices that can self-control their wavelengths using physical layer wavelength information stored in the devices. The devices share reconfigurable information interactively with each other and can contribute to compose the self-reconfigurable (metamorphic) network systems. To verify the proposed architecture, we performed the practical examinations using the subsystems with wavelength-managed 'disk filters' in a field trial (Chitose trial).
Performance of Honeywell's Inertial/GPS Hybrid (HIGH) for RNP Operations (2006)

Honeywell has developed an algorithm that tightly integrates GPS and IRS into a hybrid navigation solution adequate to achieve 100% worldwide availability of RNP 0.1 without the use of differential corrections. This algorithm, referred to as Honeywell Inertial GPS Hybrid (HIGH), improves all four of the navigation characteristics critical for RNP operations - accuracy, integrity, continuity and availability. With its increased level of availability, HIGH can support RNP operations that are lower than can be achieved with stand-alone GPS. RNP operations require the navigation system provide an integrity bound called Horizontal Integrity Limit (HIL). An RNP operation can proceed as long as the HIL remains below the threshold required for that operational level. On average, stand-alone HILs are at least 50% worse than HIGH HILs under good satellite geometries, and become significantly degraded or unavailable when in RAIM holes or during GPS outages. HIGH enhances system continuity by coasting on the inertial when no satellite measurements are available. Honeywell has applied the HIGH technology on both military and commercial aircraft platforms. Operational benefits of HIGH are examined and contrasted with stand-alone GPS based solutions. HIGH is based on Honeywell's solution separation method to provide the integrity level and the Fault Detection and Exclusion (FDE) capability. With this method, a bank of Kalman filters is used to provide multiple hybrid solutions, each excluding different combinations of zero, one or two satellites. The algorithm detects and isolates a satellite failure by comparing the various solutions. Since one of the solutions will not contain the effects of the satellite error, an uncorrupted solution is always available. Appendix R of RTCA/DO-229C provides the requirements and test procedures for tightly integrated GPS/Inertial systems. Honeywell's HIGH implementations have demonstrated compliance to Appendix R. Compliance to Appendix R is critical to ensure a consistent basis for certification for these types of systems. The paper provides results from flight tests and simulations implementing the HIGH technology. These results support the claimed enhanced performance for integrity, continuity and availability and are contrasted with stand-alone GPS systems. The results clearly show that HIGH can support lower RNP operations such as RNP 0.1 as well as future lower RNP levels. Plans for enhancing the performance in future applications are also examined. I. INTRODUCTION The required navigation performance (RNP) concept allows aircraft to operate in a defined airspace based on the
Magnetic Field Analysis in Buried Pipe Detection (1987)

Mangetic detection is known as a useful method to detect the position of a buried pipe. The detection, however, becomes erroneous except in the case of a single pipe-line. We have considered a case of two pipe-lines running parallel each other to gain a theoretical understanding of the error cause, and compared the results analyzed to those experimentally measured. Both results are in good agreement. The error is due to an earth current leaking from a considered line toward another line nearby.
A method to remove the influence of fixative concentration on post-mortem T <sub>2</sub> maps using a Kinetic Tensor model (2020)

Abstract Formalin fixation has been shown to substantially reduce T 2 estimates when performing post-mortem imaging, primarily driven by the presence of bulk fixative in tissue. Prior to scanning, post-mortem tissue samples are often placed into a fluid that has more favourable imaging properties, such as matched magnetic susceptibility. This study investigates whether there is any evidence for a change in T 2 in regions close to the tissue surface in post-mortem T 2 maps due to fixative outflux into this surrounding fluid. Furthermore, we investigate whether a simulated spatial map of fixative concentration can be used as a confound regressor to reduce T 2 inhomogeneity. To achieve this, T 2 maps and diffusion tensor estimates were obtained in 14 whole, formalin fixed post-mortem brains placed in fluorinert approximately 48 hours prior to scanning. This consisted of 7 brains fixed with 10% formalin and 7 brains fixed with 10% neutral buffered formalin (NBF). Fixative outflux was modelled using a Kinetic Tensor (KT) model, which incorporates voxelwise diffusion tensor estimates to account for diffusion anisotropy and tissue-specific diffusion coefficients. Brains fixed with 10% NBF revealed a spatial T 2 pattern consistent with the modelled fixative outflux. Confound regression of fixative concentration reduced T 2 inhomogeneity across both white and grey matter, with the greatest reduction attributed to the KT model vs simpler models of fixative outflux. No such effect was observed in brains fixed with 10% formalin. Correlations with ferritin and myelin proteolipid protein (PLP) histology lead to an increased similarity for the relationship between T 2 and PLP for the two fixative types after KT correction. Only small correlations were identified between T 2 and ferritin before and after KT correction.
Guessing random additive noise decoding with soft detection symbol reliability information - SGRAND (2019)

We recently introduced a noise-centric algorithm, Guessing Random Additive Noise Decoding (GRAND), that identifies a Maximum Likelihood (ML) decoding for arbitrary code-books. GRAND has the unusual property that its complexity decreases as code-book rate increases. Here we provide an extension to GRAND, soft-GRAND (SGRAND), that incorporates soft detection symbol reliability information and identifies a ML decoding in that context. In particular, we assume symbols received from the channel are declared to be error free or to have been potentially subject to additive noise. SGRAND inherits desirable properties of GRAND, including being capacity achieving when used with random code-books, and having a complexity that reduces as the code-rate increases.
Preliminary results of a new proposal for objective human independent striae measurement (2017)

Optical glasses with certain inner quality e.g. low striae content are essential for good optical systems. A stria is a small local change in the refractive index inside the glass resulting in a wave front distortion that can cause blurring of the image. During the production process of optical glass, striae are observed by measuring it with the so-called shadow graph method. This simple measurement displays a stria as a shadow on an observation screen. A human operator evaluates the contrast by comparing it with references. The new proposed approach uses a digital camera and image processing to measure human independent the stria level. A first repeatability measurement shows wave front deviation (maximum deviation, peak-topeak) of less than +/- 8 nm.
Effects of Dry Period Length on Milk Yield and Mammary Epithelial Cells (2004)

A dry period, typically 40 to 60 d, between lactations is believed to be required to maximize milk yield in the subsequent lactation. Several hypotheses have been proposed to explain the requirement for the dry period, including (1) replenishment of body reserves, (2) regeneration of mammary tissue, and (3) optimization of benefits from endocrine events near the time of parturition. Continuously milked cows or glands have depressed milk yields but no differences in mammary DNA content or cell number. Nutritional status and endocrine hormones are not factors in reduced milk yield in continuously milked glands. Data from continuous lactation studies suggest that depressed milk yields are due to reduced functionality of mammary parenchyma. There is a need to reevaluate effects of continuous lactation on milk yield in today's high-producing dairy cow because studies on this topic were done using cows achieving peak milk production of 18 to 30 kg/d compared with 45 to 50 kg/d in today's dairy cows. Another factor that has not been considered in conjunction with current milk production levels is the use of bovine somatotropin (bST). Supplementation with bST increases milk yield, improves lactation persistency, and may improve milk yield in continuously milked cows. Future research goals are to examine the effects of continuous lactation in high-producing cows and to determine the effects of bST on milk yield and mammary functionality in continuously milked cows.
Duration and intonation in emotional speech (1993)

Three experiments investigated the role of duration and intonation in the expression of emotions in natural and synthetic speech.Two sentences of an actor portraying seven emotions (neutral, joy, boredom, anger, sadness, fear, indignation) were acoustically analyzed.By copying pitch and duration of the original utterances to a monotonous one, it could be shown that both factors were sufficient to express the various emotions.In the second part, rules about intonation and duration were derived and tested.These rules were applied to resynthesized natural speech and synthetic speech generated from LPC-coded diphones.The results showed that emotions can be expressed accurately by manipulating pitch and duration in a rule-based way.
Antibody directed enzyme prodrug therapy (ADEPT): clinical report. (1992)

Following an extensive series of studies in nude mice with human xenografts a pilot scale clinical trial of antibody directed enzyme prodrug therapy has been initiated. The principle is to activate a relatively inert prodrug to an active cytotoxin by a tumour located enzyme. In the first stage of the study a prodrug para-N-(mono-2-chloroethyl monomesyl)-aminobenzoyl glutamic acid was administered to six patients with advanced colorectal cancer in a dose escalating protocol. Nausea and vomiting occurred as the only discernible toxic effect at the higher dose levels. Three of these patients and two other patients with advanced disease have proceeded to the second stage of the study in which an antibody-enzyme conjugate was given IV, followed after 36-48 h by a galactosylated anti-enzyme antibody. When plasma enzyme levels had become undetectable the patients received multiple doses of the prodrug. At the lower doses toxicity was minimal as were clinical responses. Two patients received higher doses which resulted in myelosuppression and temporary regression of advanced disease. No complications resulted from administration of the antibody-enzyme complex or enzyme inactivating antibody. The myelosuppression is attributable to the relatively long half-life of the active drug formed from the prodrug used in the present study.
Test vectors development and optimization for a microprocessor (1980)

This paper describes a method for generating and optimizing test vectors for a microprocessor, with the aid of a fault simulator implemented entirely by hardware. The development and optimization of test vectors has been done on a tester, with the fault simulator plugged directly into the test head. The fault simulator is capable of automatically injecting over a thousand single or multiple stuck faults in the sequential and combinatorial parts of the microprocessor. The test vectors developed by a programmer working interactively with the tester were applied through the tester to the fault simulator, and the percent of faults detected was measured. The vectors were developed and optimized for the 1802 microprocessor, with the objective of detecting 100% of the single stuck faults with a minimum set of vectors. Experimental results show that 99.7% of the single stuck faults are being detected with approximately 14,000 vectors.
The Effect of Sandblasting of UHMWPE Substrate on the Wear Resistance of Hydrogen-Containing Carbon Coating (2008)

Surface asperities were made on the surface of UHMWPE by sandblasting with sodium hydrogen carbonate abrasive in order to enhance the adhesion of hydrogen-containing carbon (HCC) coating to substrate. Sodium hydrogen carbonate abrasive was used because it easily solutes in hot water and the blasted abrasive stuck into the surface of UHMWPE can be entirely removed by washing with hot water. The HCC coating was deposited on the polished UHMWPE substrate and blasted substrate by RF-plasma CVD method. Friction test was conducted with the ball-on-disk tribometer in the distilled water. As the results of SEM observation and Raman spectroscopy analysis of the friction track on the HCC coating, it was confirmed that a substantial quantity of HCC coating deposited on the blasted substrate was remained on the friction track as compared with the polished substrate. It is concluded that the appropriate blasting treatment of UHMWPE substrate enhances the adhesiveness of the HCC coating to the substrate and improves wear resistance of HCC coating.

Evaluation of nonviral risk factors for nasopharyngeal carcinoma in a high‐risk population of Southern China (2009)

To understand the role of environmental and genetic influences on nasopharyngeal carcinoma (NPC) in populations at high risk of NPC, we have performed a case-control study in Guangxi Province of Southern China in 2004-2005. NPC cases (n = 1,049) were compared with 785 NPC-free matched controls who were seropositive for IgA antibodies (IgA) to Epstein-Barr virus (EBV) capsid antigen (VCA)-a predictive marker for NPC in Chinese populations. A questionnaire was used to capture exposure and NPC family history data. Risk factors associated with NPC in a multivariant analysis model were the following: (i) a first, second or third degree relative with NPC [attributable risk (AR)= 6%, odds ratio (OR) = 3.1, 95% confidence interval (CI) = 2.0-4.9, p < 0.001]; (ii) consumption of salted fish 3 or more than 3 times per month (AR = 3%, OR = 1.9, 95% CI = 1.1-3.5, p = 0.035); (iii) exposure to domestic wood cooking fires for more than 10 years (AR = 69%, OR = 5.8, 95% CI = 2.5-13.6, p < 0.001); and (iv) exposure to occupational solvents for 10 or less years (AR = 4%, OR = 2.6, 95% CI = 1.4-4.8, p = 0.002). Consumption of preserved meats or a history of tobacco smoking were not associated with NPC (p > 0.05). We also assessed the contribution of EBV/IgA/VCA antibody serostatus to NPC risk-32.2% of NPC can be explained by IgA+ status. However, family history and environmental risk factors cumulatively explained only 2.7% of NPC development in NPC high risk population. These findings should have important public health implications for NPC risk reduction in endemic regions.
Effect of non-thermal air atmospheric pressure plasma jet treatment on gingival wound healing (2016)

Non-thermal atmospheric pressure plasmas have been applied in the biomedical field for the improvement of various cellular activities. In dentistry, the healing of gingival soft tissue plays an important role in health and aesthetic outcomes. While the biomedical application of plasma has been thoroughly studied in dentistry, a detailed investigation of plasma-mediated human gingival fibroblast (HGF) migration for wound healing and its underlying biological mechanism is still pending. Therefore, the aim of this study is to apply a non-thermal air atmospheric pressure plasma jet (NTAAPPJ) to HGF to measure the migration and to reveal the underlying biological mechanisms involved in the migration. After the characterization of NTAAPPJ by optical emission spectroscopy, the adherent HGF was treated with NTAAPPJ or air with a different flow rate. Cell viability, lipid peroxidation, migration, intracellular reactive oxygen species (ROS), and the expression of migration-related genes (EGFR, PAK1, and MAPK3) were investigated. The level of statistical significance was set at 0.05. NTAAPPJ and air treatment with a flow rate of 250–1000 standard cubic centimetres per minute (sccm) for up to 30 s did not induce significant decreases in cell viability or membrane damage. A significant increase in the migration of mitomycin C-treated HGF was observed after 30 s of NTAAPPJ treatment compared to 30 s air-only treatment, which was induced by high levels of intracellular reactive oxygen species (ROS). An increase in migration-related gene expression and EGFR activation was observed following NTAAPPJ treatment in an air flow rate-dependent manner. This is the first report that NTAAPPJ treatment induces an increase in HGF migration without changing cell viability or causing membrane damage. HGF migration was related to an increase in intracellular ROS, changes in the expression of three of the migration-related genes (EGFR, PAK1, and MAPK1), and EGFR activation. Therefore, NTAAPPJ for gingival tissue healing is a promising method for health and aesthetic outcomes.
Association study of 182 candidate genes in anorexia nervosa (2010)

We performed association studies with 5,151 SNPs that were judged as likely candidate genetic variations conferring susceptibility to anorexia nervosa (AN) based on location under reported linkage peaks, previous results in the literature (182 candidate genes), brain expression, biological plausibility, and estrogen responsivity. We employed a case-control design that tested each SNP individually as well as haplotypes derived from these SNPs in 1,085 case individuals with AN diagnoses and 677 control individuals. We also performed separate association analyses using three increasingly restrictive case definitions for AN: all individuals with any subtype of AN (All AN: n = 1,085); individuals with AN with no binge eating behavior (AN with No Binge Eating: n = 687); and individuals with the restricting subtype of AN (Restricting AN: n = 421). After accounting for multiple comparisons, there were no statistically significant associations for any individual SNP or haplotype block with any definition of illness. These results underscore the importance of large samples to yield appropriate power to detect genotypic differences in individuals with AN and also motivate complementary approaches involving Genome-Wide Association (GWA) studies, Copy Number Variation (CNV) analyses, sequencing-based rare variant discovery assays, and pathway-based analysis in order to make up for deficiencies in traditional candidate gene approaches to AN.
