Electromagnetic propagation prediction inside aircraft cabins (2004)

Electromagnetic propagation models for signal strength prediction within aircraft cabins are essential for evaluating and designing a wireless communication system to be implemented onboard aircraft. A model was developed using Wireless Valley's SitePlanner; which is commercial grade software intended for predictions within office buildings. The performance of the model was evaluated through a comparison with test data measurements taken on several aircraft. The comparison concluded that the model can accurately predict power propagation within the cabin. This model can enhance researchers' understanding of power propagation within aircraft cabins and will aid in future research.
A Concept for Navigation and Communication using Satellites (1966)

Of all man-made objects, satellites are unique in their ability to ‘see’ large regions of the Earth at one time. Because of this ability, they can serve as relays to provide the advantages of line-of-sight communications between widely separated points on the Earth. They have another useful characteristic also—their locations in space can be determined to high accuracy, hence they can be used as position references for navigation or surveying.
Drug use, travel and HIV risk (2002)

A study was conducted to examine the travel experiences of a community sample of 160 drug users and 44 non-users recruited as part of a study of HIV risk. Of the sample, 47% (96/204) reported intercity travel in the previous ten years. Results showed that men were more likely to travel than women, Anglos more than minorities, and young persons more than old. When travellers testing HIV-seropositive (n = 13) were compared with seronegative travellers, HIV-positive travellers reported more sex while travelling than HIV-negative persons, but virtually all of the difference reported involved sex with condoms. There were no significant differences in sex risk behaviours while travelling between drug users and non-drug users, or in sex risk behaviors between drug injectors and non-injectors. Travellers had fewer injection partners while travelling than they had while at home. There was also a significant difference in number of sex partners with whom a condom was not used, with fewer sex partners while travelling.
ON THE IMPROVEMENT OF FATIGUE RESISTANCE AND SAFETY OF BUTT WELDS. IN: FATIGUE LIFE: ANALYSIS AND PREDICTION (1986)

This paper proposes a new method, substantiated experimentally, to improve the fatigue resistance and safety of butt welds. Test results indicate that, by placing the butt weld in the plane of maximum shear stress, the fatigue life is greatly increased and the fatigue crack propagation path is diverted to the base metal. Consequently, the critical crack size will depend on the fracture toughness of base metal and the safety of butt weld is improved. Also, by removing the reinforcement, the fatigue crack initiation location and the propagation path can be moved to base metal from weld toe; as a result, the fatigue life and the safety of butt weld will depend on the mechanical properties of base metal.
Cycloaddition reactions of nitrosoalkenes and azoalkenes with cyclopentadiene and other dienes (1979)

α-Nitrosostyrene, when generated from α-chloroacetophenone oxime in the presence of cyclopentadiene, forms a 1 : 1 adduct. This adduct has been formulated as the oxazine derivative (1a) which is formally derived from its two components by 4 + 2 cycloaddition, the nitrosoalkene acting as the 4-electron component. Several similar reactions have been observed between this and related nitrosoalkenes and dienes. Indene and α-morpholinostyrene add in a similar way to α-nitrosostyrene. 2,2-Dichloronitrosoethylene is exceptional in forming a different type of adduct (9) with cyclopentadiene; the reasons for this are discussed. Azoalkenes H2CC(Ph)NNX undergo cycloaddition with cyclopentadiene in an analogous manner to that of α-nitrosostyrene, giving pyridazine derivatives (11). Several similar additions of azoalkenes to electron-rich dienes and olefins have been observed, the ease of the reactions reflecting the strength of the frontier orbital interaction between the two components.

Failure Prediction for Rod Pump Artificial Lift Systems (2010)

Abstract Well failures in oil field assets lead to production loss and can greatly increase the operational expense. Predicting well failures before they occur can dramatically improve performance, such as by adjusting operating parameters to forestall failures or by scheduling maintenance to reduce unplanned repairs and to minimize downtime. This paper presents failure prediction framework and algorithms for rod pump artificial lift systems. It adapts state-of-the-art data mining approaches to learn patterns of dynamical pre-failure and normal well time series records, and to use these patterns to make failure predictions. Also, we develop a semi-supervised learning technique, called "random peek", in order to adjust the training process to cover more feature space and to overcome the bias caused by limited training samples. The data set from this paper is taken from a real-world asset using rod pump artificial lift systems. The results show that the failure prediction framework is capable of capturing future rod pump and tubing failures.
Diabetic foot ulcers (2006)

<h3>Abstract</h3> It remains to be understood how biological motion is hierarchically computed, from discrimination of local “life motion” animacy to global dynamic body perception. Here, we addressed this functional separation of the correlates of the perception of life motion, defined as characteristic for the local motion of parts of living beings, from perception of global motion of a body. We hypothesized that life motion processing can be isolated, by using a single dot motion perceptual decision paradigm featuring the biomechanical details of local realistic motion of a single joint. To ensure that we were indeed tackling processing of biological motion properties we used a discrimination instead of detection task. We discovered using representation similarity analysis that two key early dorsal and two ventral stream regions (visual motion selective hMT+ and V3A, extrastriate body area EBA and a region within fusiform gyrus FFG) showed robust and separable signals related to encoding of life motion and global motion. These signals reflected two independent processing stages, as revealed by representation dissimilarity analysis and deconvolution of fMRI responses to each motion pattern. This study showed that higher level pSTS encodes both classes of biological motion in a similar way, revealing a higher-level integrative stage, reflecting scale independent biological motion perception. Our results reveal a two-stage framework for neural computation of biological motion, with an independent contribution of dorsal and ventral regions for the initial stage.
Basic studies on gene therapy of human malignant melanoma by use of the human interferon β gene entrapped in cationic multilamellar liposomes.: 1. Morphology and growth rate of six melanoma cell lines used in transfection experiments with the human interferon β gene (2001)

Six cell lines of human malignant melanoma: A375, A375.2, G361, HMV-1, MM8.1 and WM115 were seeded at densities of 1x10(4) cells/ml, 2 x 10(4) cells/ml or 3 x 10(4) cells/ml of RPMI medium supplemented with 10% fetal calf serum and antibiotics in a humidified atmosphere of 5% CO2 at 37 degrees C. A375 cells were also grown in Dulbecco's minimum Eagle's medium (DMEM medium). The morphology was studied by phase contrast light microscopy. At 4 days after seeding the colonies of A375 cells and HMV-1 cells were oval-shaped, the cells were polyhedrical and were making contact with each other regularly. The remaining cells were scattered, more elongated, and made contact randomly. G361 cells and MM8.1 cells tended to form superposed layers before 100% confluency was achieved. There were great differences in the growth rate and doubling time of melanoma cells. The doubling time in day 1 was short (around 6-12 h) in the case of A375, G361 and HMV-1 cells, longer (around 18 h) in the case of MM8.1 cells and very long (ranging between 26 and 89 h) for A375.2 and WM115 cells. There were also differences in the doubling time of cells as a function of the cell density at seeding. On the other hand, except for MM8.1 cells, there were differences between the doubling time in day 2 compared to day 1.

Through seaweed bioethanol production, the Project aims to combat global warming by contributing an alternative energy to fossil fuel. This paper outlines the results of the project's feasibility research conducted by Tokyo Fisheries Promotion Foundation.
Is asparagine-linked protein glycosylation an obligatory requirement for angiogenesis? (1993)

Dependence of protein N-glycosylation on capillary endothelial cell proliferation has been studied. Amphomycin, a potent N-glycosylation inhibitor, inhibited capillary endothelial cell proliferation in a dose-dependent manner. beta-Agonist isoproterenol as well as other intracellular cAMP enhancing agents, viz. cholera toxin, prostaglandin E1 and 8Br-cAMP, also enhanced capillary endothelial cell proliferation. In addition to cell proliferation, isoproterenol also enhanced protein glycosylation in these cells. Isoproterenol effect was mediated by beta-adrenoreceptors, as it got reduced on pre-treatment of cells with either atenolol or ICI 118, 551 or propranolol. Furthermore, isoproterenol stimulation of protein glycosylation by exogenous dolichyl monophosphate and its inhibition by tunicamycin (GlcNAc-1P transferase inhibitor) supported the concept that isoproterenol specifically stimulated protein N-glycosylation event(s) in the cell.
Performance evaluation of spherical parallel platforms for humanoid robots (2006)

SUMMARY This paper presents a simple methodology for the quantitative and qualitative analysis of the performance of spherical parallel platforms. The quaternion formulation is used to represent the possible rotations, showing the workspace as a three-dimensional (3-D) solid object. The singularities of the platform intersect graphically with its workspace, allowing a graphical study of the mechanism kinematics. The performance criterion considered here has been the local dexterity of the manipulator. This methodology has been used to study and analyze three known orientation parallel platforms: 3- R RR, 3-U P U-wrist, and 2-U P S-1- R U. The objective of this study is to analyze the ability of these platforms to be utilized as mechanisms for the neck and shoulders of humanoid robots. Finally, the forces on actuators in some typical motions for neck and shoulder are plotted.

The impact of nausea and vomiting on women: a burden of early pregnancy (2000)

Nausea and vomiting are troublesome symptoms occurring in the first trimester of pregnancy. The aim of this study was to describe the impact these symptoms have on women in early pregnancy by interviewing, using a structured questionnaire, 593 pregnant women presenting with nausea and vomiting in the first trimester of pregnancy. The women were asked to complete the Rhodes index of nausea and vomiting and the MOS 36 Short Form Health Survey (SF-36). Symptoms of nausea and vomiting started early in pregnancy. Nausea was the most troublesome symptom experienced by women, both in its duration and intensity. Low scores for the SF-36 were found for all items, particularly physical functioning, energy and social functioning. The women described substantial effects on working, household duties and parenting activities. Findings from this study suggest nausea and vomiting in early pregnancy has a profound impact on women's general sense of well-being and day to day life activities.
Composition and Enzymatic Activity of the Extracellular Matrix Secreted by Germlings of<i>Botrytis cinerea</i> (1999)

Germlings of Botrytis cinerea, an important fungal pathogen of plants, produce an extracellular matrix (ECM), or ensheathing film, that serves, in part, in their attachment (R. P. Doss, et al., Appl. Environ. Microbiol. 61:260-265, 1995). The composition of this film has been ascertained by using samples obtained by growing germlings on a glass surface, removing the fungal mycelium by vigorous washing, and collecting the tightly attached film by scraping the substratum with a razor blade. Slightly over half of the dry weight of the ECM was found to be carbohydrates (about 20%), proteins (about 28%), and lipids (about 6%). Hydrolysis of the carbohydrate portion of the ECM revealed that glucose was the most prominent monosaccharide present, comprising about 60% of the total monosaccharides. Also present were mannose (about 35%) and myo-inositol (about 5%). The proteinaceous fraction of the ECM was made up of a number of polypeptides separable by polyacrylamide gel electrophoresis. The lipid fraction of the ECM, analyzed by thin-layer chromatography, was made up of several simple lipid components, including free fatty acid, mono- and triacylglycerol, wax ester, fatty alcohol, and several unidentified components. No complex lipids were detected. Isolated ECM exhibited polygalacturonase and laccase activity and was able to catalyze the hydrolysis of p-nitrophenyl butyrate, a model substrate for assessing cutinase activity. Cellulase, pectin lyase, and pectin methyl esterase activities were noted with both heated and unheated ECM preparations. Proteinase activity was not detected.
Accurate on-line avatar control with collision anticipation (2007)

Interactive control of a virtual character through full body movement has a wide range of applications. However, there is a need for systems that accurately reproduce the motion of a performer while accounting for surrounding obstacles. We propose an approach based on a Prioritized Inverse Kinematics constraint solver. Several markers are placed on the user's body. A set of kinematic constraints make the virtual character track these markers. At the same time, we monitor the instantaneous displacements of a set of geometric primitives, called observers, attached to different parts of the virtual character. When an observer enters the influence area of an obstacle, its motion is damped by means of automatically created preventive constraints. The IK solver satisfies both maker and preventive constraints simultaneously, yielding postures of the virtual character that remain close to those of the user, while avoiding collisions with the virtual environment. Our performance measurements show the maturity of the IK technology for real-time full-body interactions.

On the Reaction Pathway for the Hydrogenation of Acetylene and Vinylidene on Pd(111) (2000)

The pathways for the hydrogenation of adsorbed acetylene and vinylidene on Pd(111) are investigated using temperature-programmed desorption and infrared reflection−absorption spectroscopies. The chemistry of the vinyl intermediate formed by the hydrogenation of both species is investigated by adsorbing vinyl iodide on Pd(111) where it is found that vinyl species hydrogenate more rapidly than adsorbed acetylene, indicating that the rate-limiting step in acetylene hydrogenation is the addition of the first hydrogen to acetylene to form a vinyl species. Infrared spectroscopy also reveals that vinyl species convert to ethylidynes as Pd(111) is heated above ∼160 K. The hydrogenation of vinylidene by up to ∼0.2 Torr of hydrogen involves intermediate ethylidyne species in accord with this observation. Surprisingly, the rate constant for the conversion of vinylidene into ethylidyne is identical to that for the titration of ethylidyne from the surface by hydrogen, an effect that may be explained in terms of the different saturation coverages of the two species.
Fibroblast markers in labial salivary gland biopsies in progressive systemic sclerosis. (1990)

Labial salivary gland (LSG) biopsies from 13 patients were studied. Three were normal glands, five showed fibrosis induced by progressive systemic sclerosis (PSS) and five more had PSS-induced fibrosis combined with and focal sialadenitis compatible with Sjögren's syndrome (SS). Monoclonal antibodies to proline-4-hydroxylase (alpha PH or 5B5-A) and the carboxyterminal domain of human type I procollagen (alpha pC or M-38) were used as fibroblast markers. Immunostaining was done with avidin-biotin-peroxidase complex (ABC). Using various sample controls (including cultured fibroblasts and specimens enriched for lymphocytes, plasma cells, granulocytes, monocytes and dendritic cells) as well as analysis of various LSG resident cells, the specificity of the alpha PH and alpha pC markers for fibroblasts was established. Cross reactions were only seen with plasma cells and acinar cells containing the beta subunit of PH or disulfide isomerase involved in SS-SH interchange reactions in these secretory cells. All fibroblasts in fibroblast monolayer cultures at their logarithmic phase of growth stained with the fibroblast markers studied, but false negative staining was seen with resting, mature fibroblasts in dense connective tissue in LSG sections. Therefore, it can be concluded that proline 4-hydroxylase and the COOH-terminal domain of type-I procollagen both indicate fibroblast involvement in collagen (type l) synthesis and thus identify active but not resting fibroblasts. PH+ fibroblast-like cells and pC+ fibroblasts were both more frequent in PSS LSGs than in normal glands, suggesting active local fibroblast involvement in PSS.(ABSTRACT TRUNCATED AT 250 WORDS)
CSRR Loaded Microstrip Array Antenna With Low Sidelobe Level (2015)

A novel technique for obtaining low sidelobes pattern in a planar microstrip array antenna is proposed. This technique involves the addition of two external complementary split ring resonators (CSRRs) at both the ends of each row of the antenna in the ground plane. These two CSRRs together produce an interferometer pattern for the reduction of sidelobes. An 8×4 planar array at 9.9 GHz is designed and fabricated to demonstrate the concept and a sidelobe reduction of 4.3 dB achieved.

On the use of code mobility mechanisms in real-time systems (2011)

Applications with soft real-time requirements can benefit from code mobility mechanisms, as long as those mechanisms support the timing and Quality of Service requirements of applications. In this paper, a generic model for code mobility mechanisms is presented. The proposed model gives system designers the necessary tools to perform a statistical timing analysis on the execution of the mobility mechanisms that can be used to determine the impact of code mobility in distributed real-time applications.
Algorithm for Peak to Average Power Ratio Reduction operating at Symbol Rate (2005)

Multi-tone or multi-code modulation schemes, like OFDM or WCDMA, have the disadvantage of a large peak to average power ratio (PAPR). Efficient transmission of such high data rate signals is limited by the non-linearity of the power amplifier (PA). This causes interference within and outside the signal band. Without any measures, this interference can be reduced only with a sufficient input back off of the PA. In order to achieve a better efficiency in the PA, in addition to pre-distortion methods, the signal PAPR should be reduced. The paper shows a new algorithm which limits the PAPR without introducing any additional out-of band emission. Simulations for the WCDMA downlink signal are presented and compared to a state of the art solution.
Changes During Early Soybean Seed and Axes Deterioration: II. Lipids (1990)

Peroxidative changes in seed lipids are thought to be a major cause of seed deterioration during storage. This study was conducted to determine the fatty‐acid composition of soybean [ Glycine max (L.) Merr.] seeds, axes, and mitochondria during the early stages of deterioration. High‐quality seed lots of ‘Union’ and ‘Desoto’ soybean were stored at 25 °C and 115 g kg ‐ 1 seed moisture for 10 and 12 months, respectively. Seeds were sampled at frequent intervals and the fatty‐acid composition of storage and membrane lipids from seeds, axes, and mitochondria were determined. There were no detectable changes in the fatty‐acid composition of storage lipids from whole seeds or axes during the storage period for either seed lot, despite the substantial decline in seed vigor. There was a slight decrease in the percentage of unsaturated fatty acids in the membrane lipids of excised axes from Desoto seeds. The percentage of unsaturated fatty acids in the mitochondria from excised axes declined early during storage. The double‐bond index (DBI) of lipids from mitochondria of the Union axes fell from 1.76 at the beginning of storage to 1.60 after 10 months. Similar declines of 1.79 to 1.70 after 1 yr in storage were seen for the Desoto axes. Mitochondria! respiration and DBI were highly correlated for both seed lots. These data suggest that the decreases in mitochondrial respiration during storage may be associated with peroxidative changes in mitochondrial lipids and that these changes occurred prior to loss in seed vigor.
New Low-Leakage Power-Rail ESD Clamp Circuit in a 65-nm Low-Voltage CMOS Process (2010)

A new low-leakage power-rail electrostatic discharge (ESD) clamp circuit designed with consideration of the gate leakage issue has been proposed and verified in a 65-nm low-voltage CMOS process. Consisting of the new low-leakage ESD-detection circuit and the ESD clamp device of a substrate-triggered silicon-controlled rectifier, the new proposed power-rail ESD clamp circuit realized with only thin-oxide (1-V) devices has a very low leakage current of only 116 nA at room temperature (25°C ) under the power-supply voltage of 1 V. Moreover, the new proposed power-rail ESD clamp circuit can achieve ESD robustness of over 8 kV, 800 V, and over 2 kV in human-body-model, machine-model, and charged-device-model ESD tests, respectively.
