Correlation of Plasma Process Conditions, Phase Content, and Photocatalytic Performance of Induction Plasma-Sprayed Titania Coatings (2005)

Abstract Systematic variation of the induction plasma spray (IPS) conditions, i.e. (i) plasma power, (ii) carrier gas flow rate, and (iii) powder feed rate was performed to deposit TiO2 coatings using statistical design of experiments (SDE) methodology. The microstructure, surface morphology, and anatase-rutile ratio of the coatings were studied by grazing-incidence X-ray diffraction (GIXD) and surface mapping with micro-probe Raman spectroscopy to determine the spatial phase distribution of anatase and rutile. The photocatalytic activity of the TiO2 coatings was tested by decomposition of 4-chlorophenol in aqueous solution in the dark and under UV irradiation. The rates of pH changes measured were compared with those of standard Degussa P-25 coatings. The photocatalytic activity of the samples shows a reasonable correlation with the phase content and the plasma processing conditions prevailing during coating deposition.

Note: Optimization and calibration for auto-cumulative flowmeter in horizontal oil-water two-phase flow (2018)

This note presented the optimization and calibration for a novel auto-cumulative flowmeter (ACF) to measure the oil flow rate in horizontal oil-water two-phase segregated flow. By using the finite element method, the electrode geometry of the probe in the ACF was designed, optimized, and simulated for oil accumulation measurement. Considering the practical application of ACF, a novel circuit for ACF with the optimized geometry of the probe was designed, simulated, and analyzed. The experiment for oil-water two-phase segregated flow with the novel circuit was carried out to calibrate the ACF. The calibration results can provide a theoretical basis and technical reference for the practical application of ACF.

Building a virtual system of systems using docker swarm in multiple clouds (2016)

The software industry has been embracing the multi-cloud infrastructure for the design and adaptation of complex and distributed software systems. This new hybrid cloud infrastructure makes it possible to mix and match platforms and cloud providers for various software development activities. There are several benefits of the multi-cloud infrastructure such as lower level of vendor lock-in and minimize the risk of widespread data loss or downtime. However, it has many challenges such as non-standard and inherent complexity due to different technologies, interfaces, and services. Docker has introduced container-based software development approach in the past few years and gaining popularity in the software industry. It has recently introduced its distributed system development tool called Swarm, which extends the Docker container-based software development process on multiple hosts in multiple clouds without any interoperability issue. Docker Swarm-based distributed software development is a newborn approach for the cloud industry; nonetheless, it has a huge potential to provide multi-cloud development environment without worrying the complexity of it. This paper presents the simulation of building a virtual system of systems (SoS) for the distributed software development process on multiple clouds. This simulation of virtual SoS is based on Docker Swarm, VirtualBox, Mac OS X, nginx and redis. However, the same SoS can be created on any of the Docker supported cloud by just changing the driver name to the desired cloud name such as Amazon Web Services, Microsoft Azure, Digital Ocean, Google Compute Engine, Exoscale, Generic, OpenStack, Rackspace, IBM Softlayer, VMware vCloud Air.
Real World Scrum A Grounded Theory of Variations in Practice (2020)

Scrum, the most popular agile method and project management framework, is widely reported to be used, adapted, misused, and abused in practice. However, not much is known about how Scrum actually works in practice, and critically, where, when, how and why it diverges from Scrum by the book. Through a Grounded Theory study involving semi-structured interviews of 45 participants from 30 companies and observations of five teams, we present our findings on how Scrum works in practice as compared to how it is presented in its formative books. We identify significant variations in these practices such as work breakdown, estimation, prioritization, assignment, the associated roles and artefacts, and discuss the underlying rationales driving the variations. Critically, we claim that not all variations are process misuse/abuse and propose a nuanced classification approach to understanding variations as <i>standard, necessary, contextual,</i> and <i>clear deviations</i> for successful Scrum use and adaptation.
Optical coherence microscopy as a novel, non-invasive method for the 4D live imaging of early mammalian embryos (2017)

Imaging of living cells based on traditional fluorescence and confocal laser scanning microscopy has delivered an enormous amount of information critical for understanding biological processes in single cells. However, the requirement for a high numerical aperture and fluorescent markers still limits researchers' ability to visualize the cellular architecture without causing short- and long-term photodamage. Optical coherence microscopy (OCM) is a promising alternative that circumvents the technical limitations of fluorescence imaging techniques and provides unique access to fundamental aspects of early embryonic development, without the requirement for sample pre-processing or labeling. In the present paper, we utilized the internal motion of cytoplasm, as well as custom scanning and signal processing protocols, to effectively reduce the speckle noise typical for standard OCM and enable high-resolution intracellular time-lapse imaging. To test our imaging system we used mouse and pig oocytes and embryos and visualized them through fertilization and the first embryonic division, as well as at selected stages of oogenesis and preimplantation development. Because all morphological and morphokinetic properties recorded by OCM are believed to be biomarkers of oocyte/embryo quality, OCM may represent a new chapter in imaging-based preimplantation embryo diagnostics.

Growth, Structural and Optical Characterization of ZnO Nanotubes on Disposable-Flexible Paper Substrates by Low-Temperature Chemical Method (2012)

We report the synthesis of vertically aligned ZnO nanotubes (NTs) on paper substrates by low-temperature hydrothermal method. The growth of ZnO NTs on the paper substrate is discussed; further, the structural and optical properties are investigated by scanning electron microscope (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDS), and cathodoluminescence (CL), and it was found that the ZnO NTs on paper substrate fulfill the structural and optical properties of ZnO NTs grown on other conventional substrates. This will be more beneficial in future usage of ZnO NTs in different fields and applications. Particularly, this approach opens the ways in research and development for high volume manufacturing of low-cost, flexible optoelectronics devices on disposable paper substrates and can be used in the future miniaturization trends.
2-D Finite Difference Modeling of Microwave Heating in the Prostate (1995)

Abstract Accurate prediction of temperatures in the prostate undergoing thermally-based treatments is crucial to assessing efficacy and safety. A two-dimensional transient finite difference model for predicting temperatures in prostate undergoing microwave heating via a transurethral fluid-cooled catheter is presented. Unconditional stability and good accuracy are achieved by using the alternating direction implicit method. A transverse section of the prostate centered at the urethra is modeled in cylindrical coordinates. The model geometry consists of a hollow silicone cylinder, representing the catheter, surrounded by multiple regions of tissue. Cold fluid flowing through the catheter minimizes the temperature in the periurethral tissue. This flow is modeled as a convective boundary condition at the surface between the catheter lumen and wall. The outer surface of the tissue is assumed to remain at baseline temperature. Microwave heating has both a radial and angular dependence. In order to maximize the heat to the target tissue, the microwave field emitted from the transurethral catheter focuses heat away from the rectum. Results of the numerical model for a phantom are first compared to phantom experiment results. Two catheter-related parameters which provided the best fit in the phantom study were used to extend the model to the prostate with perfusion. Pennes’ perfusion term is assumed to model the effect of perfusion on heat transfer. Different perfusion situations within the prostate are simulated.
Online Sensorless Induction Motor Temperature Monitoring (2010)

A sensorless internal temperature monitoring method for induction motors is proposed in this paper. This method can be embedded in standard motor drives, and is based on the stator windings resistance variation with temperature. A small AC signal is injected to the motor, superimposed to the power supply current, in order to measure the stator resistance online. The proposed method has the advantage of requiring a very low-level monitoring signal, hence the motor torque perturbations and additional power losses are negligible. Furthermore, temperature estimations do not depend on the knowledge of any other motor parameter, since the method is not based on a model. This makes the proposed method more robust than model-based methods. Experimental results that validate the proposal are also presented.
A Handheld Neutron-Detection Sensor System Utilizing a New Class of Boron Carbide Diode (2006)

A handheld neutron-detection sensor application is described in this paper. The sensor system utilizes a new class of boron carbide diode that interacts with incoming neutrons. To interface with the boron carbide diode, an integrated front end is designed in a 1.5-mum standard CMOS technology. With the diode and front-end microchip, a handheld neutron-detection system was realized with an embedded microcontroller for real-time processing. The handheld detector operation was then tested with a plutonium-beryllium neutron source. Test and measurement results confirm the validity of the approach and the functionality of the design
Implanted IgE-Fc.epsilon.R complexes elicit IgE-mediated activation of RBL-2H3 cells (1989)

The high-affinity receptor for IgE (Fc epsilon R) is the cellular trigger of the antigen-induced activation of mast cells and basophils. To examine the functional integrity of Fc epsilon R, we have adopted a protein implantation procedure whereby the purified receptor complex was coreconstituted with Sendai virus envelopes. The latter promoted fusion of the hybrid vesicles with recipient cells such as rat basophilic leukemia, RBL-2H3, thus serving as a vehicle for the receptor. The implanted Fc epsilon R was complexed with 125I-labeled mouse IgE (anti-DNP) to permit receptor quantification as well as specific triggering by DNP20BSA. Implantation in the presence of unlabeled rat IgE, which blocked the native receptors on the recipient RBL-2H3 cells, resulted in incorporation of up to 15 ng of receptor-bound IgE/10(6) cells. This was roughly equivalent in amount to 10-20% of the native receptors on such cells. The exocytosis which was triggered in the recipient cells by reagents that specifically recognized the implanted IgE reached between 15 and 50% of the maximal response. Various treatments that interfered with the activities of the viral envelopes reduced both receptor incorporation (3-5-fold) and cell degranulation (3-10-fold). These included separation of the receptor from the reconstituted envelopes, addition of serum to the incubation mixture (to inhibit vesicle-cell binding), and trypsinization of the virus (to inhibit vesicle-cell fusion). Poly(ethylene glycol) 8000 (4%) enhanced both the incorporation of the receptor and its functional responses. These treatments distinguished between real incorporation of IgE-Fc epsilon R complexes and other mechanisms of 125I-IgE association with the recipient cells.(ABSTRACT TRUNCATED AT 250 WORDS)

Nitrogen bridgehead compounds. Part 76 Synthesis and stereochemistry of ethyl 9‐benzylidene‐6,7,8,9‐tetrahydro‐2‐oxo‐2H‐ and 4‐oxo‐4H‐pyrido[1,2‐a]pyrimidine‐3‐carboxylates and their homologues (1989)

Abstract Ethyl 4‐oxo‐6,7,8,9‐tetrahydro‐4 H ‐pyrido[1,2‐ a ]pyrimidine‐3‐carboxylates 1–4 , their piperidine ring homologues 5–6 and their 2‐oxo isomers 7–9 were reacted with benzaldehyde. At low temperature, kinetically stable addition products were formed. Thermodynamically stable condensation products were obtained at higher temperature, which were also formed when the addition products were refluxed in benzene. The 9‐benzyl derivatives were prepared by the hydrogenation of the condensation products over Pd/C. The stereochemical features of the new compounds were determined via 1 H and 13 C nmr chemical shift and coupling constant analysis and NOE measurements.
Model for Predicting Distribution of Link Travel Times for Urban Signalized Roads (2012)

Estimation and prediction of urban travel time are acknowledged as important yet challenging topics. The traffic flow theory as developed especially for freeway traffic does not give much help for modeling urban traffic processes. Urban travel times are irregular because of several disturbances on a path. The interruption of trips at signalized intersections causes a large part of the total delay that vehicles experience on a route. These delays vary with stochastic properties of traffic flow, including stochastic arrivals and departures at signalized intersections. As a result, a wide distribution of delay (travel times) can be found for a certain traffic condition and traffic control scheme. This paper proposes a procedure for predicting the distributions of urban link travel times. The core of this procedure is the proposed model of distributions of link travel times that considers stochastic arrivals and departures at intersections and the traffic control scheme explicitly. A comparison of the distributions of link travel time predicted by the model with those derived from VISSIM simulation showed that travel time distributions can be predicted well under time-varying demand and different traffic conditions. A comparison with real-life data derived from Global Positioning System information indicates that distributions of link travel times predicted by the model can represent these real-life travel time distributions, though some discrepancies can be observed for certain links.
Altered DNA Methylation Landscapes of Polycomb-Repressed Loci Are Associated with Prostate Cancer Progression and ERG Oncogene Expression in Prostate Cancer (2013)

This work defines methylation landscapes of prostate cancer according to Gleason score, and suggests that initiating genetic events may influence the prostate cancer epigenome, which is further perturbed as prostate cancer progresses. Moreover, CpG islands with silent chromatin signatures in benign cells are particularly susceptible to prostate cancer-related hypermethylation.
Roles for redox mechanisms controlling protein kinase G in pulmonary and coronary artery responses to hypoxia (2011)

We previously reported that isolated endothelium-removed bovine pulmonary arteries (BPAs) contract to hypoxia associated with removal of peroxide- and cGMP-mediated relaxation. In contrast, bovine coronary arteries (BCAs) relax to hypoxia associated with cytosolic NADPH oxidation coordinating multiple relaxing mechanisms. Since we recently found that H(2)O(2) relaxes BPAs through PKG activation by both soluble guanylate cyclase (sGC)/cGMP-dependent and cGMP-independent thiol oxidation/subunit dimerization mechanisms, we investigated if these mechanisms participate in BPA contraction and BCA relaxation to hypoxia. The contraction of BPA (precontracted with 20 mM KCl) to hypoxia was associated with decreased PKG dimerization and PKG-mediated vasodilator-stimulated phosphoprotein (VASP) phosphorylation. In contrast, exposure of 20 mM KCl-precontracted endothelium-removed BCAs to hypoxia caused relaxation and increased dimerization and VASP phosphorylation. Depletion of sGC by organoid culture of BPAs with an oxidant of the sGC heme (10 μM 1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one) increased aerobic force generation, decreased VASP phosphorylation, and inhibited further contraction to hypoxia and changes in VASP phosphorylation. Thiol reduction with dithiothreitol increased aerobic force in BPAs and decreased PKG dimerization, VASP phosphorylation, and the contraction to hypoxia. Furthermore, PKG-1α and sGC β(1)-subunit small interfering RNA-transfected BPAs demonstrated increased aerobic K(+) force and inhibition of further contraction to hypoxia, associated with an attenuation of H(2)O(2)-elicited relaxation and VASP phosphorylation. Thus, decreases in both a sGC/cGMP-dependent and a dimerization-dependent activation of PKG by H(2)O(2) appear to contribute to the contraction of BPAs elicited by hypoxia. In addition, stimulation of PKG activation by dimerization may be important in the relaxation of coronary arteries to hypoxia.
Role of Innate and Adaptive Immunity in the Outcome of Primary Infection with Chlamydia pneumoniae, as Analyzed in Genetically Modified Mice (1999)

Abstract Infection with Chlamydia pneumoniae is a common cause of acute respiratory disease in man and is also associated with atherosclerotic cardiovascular disorder. Herein, we have compared bacterial load and immune parameters of C. pneumoniae-infected mice genomically lacking T cell coreceptors, cytokine receptors, or cytotoxic effector molecules. A protective role for CD8+ cells is shown by the enhanced severity of infection of CD8−/− or TAP-1−/−/β2-microglobulin −/− mice. CD8+ cells hindered a parasite growth-promoting role of CD4+ T cells, as indicated by the higher sensitivity to early infection of CD8−/− than CD4−/−/CD8−/− mice, which was further confirmed in experiments in which SCID mice were reconstituted with either CD4+ or CD4+ plus CD8+ T cells. Interestingly, CD4+ T cells played a dual role, detrimental early (14 and 24 days) after infection but protective at later time points (60 days after infection). The CD8+ T cell protection was perforin independent. The early deleterious role of CD4+ in the absence of CD8+ T cells was associated with enhanced IL-4 and IL-10 mRNA levels and delayed IFN-γ mRNA accumulation in lungs. In line with this, IFN-γR−/− (but not TNFRp55−/−) mice showed dramatically increased susceptibility to C. pneumoniae, linked to reduced inducible nitric oxide synthase (iNOS) mRNA accumulation, but not to diminished levels of specific Abs. The increased susceptibility of iNOS−/− mice indicates a protective role for iNOS activity during infection with C. pneumoniae. The higher sensitivity of IFN-γR−/− mice to C. pneumoniae compared with that of SCID or recombination-activating gene-1−/− mice suggested a relevant protective role of IFN-γ-dependent innate mechanisms of protection.

The infocious web search engine (2005)

In this paper we present the Infocious Web search engine [23]. Our goal in creating Infocious is to improve the way people find information on the Web by resolving ambiguities present in natural language text. This is achieved by performing linguistic analysis on the content of the Web pages we index, which is a departure from existing Web search engines that return results mainly based on keyword matching. This additional step of linguistic processing gives Infocious two main advantages. First, Infocious gains a deeper understanding of the content of Web pages so it can better match users' queries with indexed documents and therefore can improve relevancy of the returned results. Second, based on its linguistic processing, Infocious can organize and present the results to the user in more intuitive ways. In this paper we present the linguistic processing technologies that we incorporated in Infocious and how they are applied in helping users find information on the Web more efficiently. We discuss the various components in the architecture of Infocious and how each of them benefits from the added linguistic processing. Finally, we experimentally evaluate the performance of a component which leverages linguistic information in order to categorize Web pages.
