‘CloudCop’: Putting network-admin on cloud nine towards Cloud Computing for Network Monitoring (2009)

Computer Network Monitoring is an evergreen field of challenges. The recent advent of Cloud Computing, in the realm of `New Generation Networks', opens a whole new field of envisaging and implementing at least two of its aspects, namely `Software as a Service(SaaS)'and `Platform as a Service(PaaS)' in the field of Network Management(NM). In this paper, we present the design and implementation of a Network Monitoring Framework oriented towards Cloud Computing which we call `CloudCop'. The NM framework uses Web Services (WS) and Service Oriented Computing (SOC) to implement SaaS, while PaaS is provided by providing some of the features such as WS marshalling, integration, storage and persistence. Its data storage schema is made very generic to be applicable for other applications thus being in tune with the vision of SOC. It also employs a whole gamut of technologies such as WS, SOC, Mobile Agents(MA), Simple Network Management Protocol(SNMP) and is made scalable and robust enough to absorb new pieces such as Rule Engines and Ontology based Service Discovery which are planned in the next implementation phase. Therefore, this paper attempts to provide directions on the applicability of Cloud Computing for NM with a case study and implementation results paving the way for the users of such applications, network system administrators (network-admin)truly elated and therefore on `cloud nine'!
Smart test program set (TPS) (2004)

The Boeing Company has several research and development efforts focused on improving interoperability of the test station with other external systems as well as the interoperability within the test station itself. This includes integrating UUT data, test set-up, test execution, test results, repair and replace actions with other systems to provide a "closed-loop" system. One example of the "closed-loop" system is a non-intrusive tool referred to as Smart TPS (Test Program Set). Smart TPS will provide informational services to the user that reduce diagnostic test times and provide an ordered list of replacement actions based on historical data. Where possible, data are exchanged via the automatic test markup language (ATML).
Magneto-optical kerr spectroscopy and interfacial perpendicular magnetic anisotropy of (Hf,Pt)/CoFeB/MgO thin films (2015)

The magneto-optical polar Kerr spectra of CoFeB/MgO thin films on different kinds of underlayers (Hf, Pt) were investigated in order to understand the origin of the interfacial perpendicular magnetic anisotropy (PMA) in that structure. The Kerr spectra were measured by using real-time Kerr spectroscopy based on a fiber-coupled high-speed spectrometer in the photon energy range of 1.5 ~ 2.9 eV. The magneto-optical studies revealed that the magneto-optical proximity effect due to the Hf underlayer to CoFeB was weak, but the interfacial contribution of the Pt underlayer to the CoFeB was strong. The variation of the PMA as a function of the annealing conditions was also investigated, and a gradual enhancement of the PMA was observed with increasing annealing temperature for the Pt underlayer sample, but a gradual decay of the PMA was observed for the Hf underlayer sample. The magneto-optical studies showed that the formation of CoPt alloys at the Pt/CoFeB interface played an important role in the PMA of the Pt/CoFeB/MgO structure at higher annealing temperature.
Mussel adhesive protein fused with VE-cadherin domain specifically triggers endothelial cell adhesion (2018)

Endothelium is the only known completely non-thrombogenic material. In the present study, a strategy to mimic the adhesive interactions of endothelial cells (ECs) to alter the vascular microenvironment was established and applied to directing the behaviour of cells. To facilitate the regeneration of a functional endothelium in vascular lesions, we designed a recombinant mussel foot protein (Mfp-5) fused with the VE-cadherin extracellular domain EC1-2, termed VE-M. Surface coating analysis showed that recombinant VE-M successfully formed a coating on substrate materials with uniform nanorods, low roughness, and sufficient hydrophilicity. We then evaluated the effects of VE-M on the adhesion of ECs and the capture of endothelial progenitor cells (EPCs). The result demonstrated that VE-M efficiently promoted the adhesion of ECs and EPCs. The number of ECs and EPCs on VE-M was 5.5- and 1.8-fold higher, respectively, than that on bare 316L SS under static conditions, whereas there was no significant difference in the number of captured smooth muscle cells (SMCs) between VE-M and other substrates. In addition, the number of EPCs captured by VE-M was approximately four times higher than that captured by 316L SS under dynamic conditions. In particular, the result of the neutralization test indicated that VE-M specifically triggered ECs’ adhesion via the interaction of VE-cadherin EC1-2. Further investigation showed that VE-M significantly increased the levels of endogenous VE-cadherin in HUVECs as well as the endothelial eNOS content, with little or no endothelial inflammation. Our results showed that VE-M could be a promising biomimetic modification for accelerating endothelialization and vascularization in tissue engineering.
The co-immobilization of NAD and dehydrogenases and its application to bioreactors for synthesis and analysis. (1982)

A polymerizable NAD derivative, N6-[N-[N-(2-hydroxy-3-methacrylamidopropyl)carbamoylmethyl]carbamoylmethyl]-NAD, formate dehydrogenase, and malate dehydrogenase were entrapped all together in polyacrylamide gels. The entrapment was carried out by radical copolymerization, and consequently NAD was bound on the matrix which enclosed the enzymes. These gels had the function of producing L-malate from oxalacetate and formate. The L-malate production was also continuously done in a column reactor for 3 days. Another gel was similarly prepared with N6-[N-(6-methacrylamidohexyl)carbamoylmethyl]-NAD, horse liver alcohol dehydrogenase, and diaphorase. This gel was shown to catalyze the formation of resorufin from resazurin and ethanol. This gel was applicable to ethanol analysis using a fluorescence spectrophotometer to determine resorufin. The analyzer was usable for one week.
Reliability of inspection for fatigue cracks in offshore structures (1996)

Offshore structures are subject to wind and wave loading, which-eventually causes fatigue crack growth. The rate of growth of cracks depends on the load history, environment, design of joint and structure. In order to check for this growth the structure is periodically inspected with the inspection schedule designed to detect cracks before they are a danger to the structural integrity. The capability of an inspection method to detect cracks of a certain size is therefore an important aspect in establishing the schedule and maintaining the structural integrity. Also important is the capability of equipment to size the cracks, as this will determine the actions which may be taken in the event of a crack detection. The types of inspection reliability information required therefore includes probability of detection (POD), probability of false calls (spurious) and accuracy of sizing. Inspection reliability information can be obtained in a number of ways. These include anecdotal (inspection experience with particular equipment), manufacturers information, experimental determination and modelling. Each of these has its advantages and disadvantages. The offshore industry decided to explore an experimental inspection programme which led to the ICON project. The programme and the ICON project are briefly described.
Glutamate Receptor Signaling Interplay Modulates Stress-sensitive Mitogen-activated Protein Kinases and Neuronal Cell Death (1999)

Glutamate receptors modulate multiple signaling pathways, several of which involve mitogen-activated protein (MAP) kinases, with subsequent physiological or pathological consequences. Here we report that stimulation of the N-methyl-D-aspartate (NMDA) receptor, using platelet-activating factor (PAF) as a messenger, activates MAP kinases, including c-Jun NH2-terminal kinase, p38, and extracellular signal-regulated kinase, in primary cultures of hippocampal neurons. Activation of the metabotropic glutamate receptor (mGluR) blocks this NMDA-signaling through PAF and MAP kinases, and the resultant cell death. Recombinant PAF-acetylhydrolase degrades PAF generated by NMDA-receptor activation; the hetrazepine BN50730 (an intracellular PAF receptor antagonist) also inhibits both NMDA-stimulated MAP kinases and neuronal cell death. The finding that the NMDA receptor-PAF-MAP kinase signaling pathway is attenuated by mGluR activation highlights the exquisite interplay between glutamate receptors in the decision making process between neuronal survival and death.
Use of a pressure sensing sheath: comparison with standard means of blood pressure monitoring in catheterization procedures (2016)

The PSS has competitive functionality to that seen with a dedicated radial artery catheter for BP monitoring and is available immediately on sheath insertion without the added risk of radial catheterization. The sensor is structurally separated from the primary sheath lumen and readings are unaffected by device introduction through the primary lumen. Time delays and potential complications from radial artery catheterization are avoided.
Shotgun Protein Sequencing (2007)

Despite significant advances in the identification of known proteins, the analysis of unknown proteins by MS/MS still remains a challenging open problem. Although Klaus Biemann recognized the potential of MS/MS for sequencing of unknown proteins in the 1980s, low throughput Edman degradation followed by cloning still remains the main method to sequence unknown proteins. The automated interpretation of MS/MS spectra has been limited by a focus on individual spectra and has not capitalized on the information contained in spectra of overlapping peptides. Indeed the powerful shotgun DNA sequencing strategies have not been extended to automated protein sequencing. We demonstrate, for the first time, the feasibility of automated shotgun protein sequencing of protein mixtures by utilizing MS/MS spectra of overlapping and possibly modified peptides generated via multiple proteases of different specificities. We validate this approach by generating highly accurate de novo reconstructions of multiple regions of various proteins in western diamondback rattlesnake venom. We further argue that shotgun protein sequencing has the potential to overcome the limitations of current protein sequencing approaches and thus catalyze the otherwise impractical applications of proteomics methodologies in studies of unknown proteins.

Expression and secretion of the bovine coronavirus hemagglutinin-esterase glycoprotein by insect cells infected with recombinant baculoviruses (1990)

A cDNA fragment representing the hemagglutinin-esterase (HE) gene of bovine coronavirus (BCV) was inserted into the genome of Autographa californica nuclear polyhedrosis virus. Infection of insect cells with the recombinant virus resulted in the production of a 120-kilodalton disulfide-linked dimeric form of the BCV HE polypeptide. Deletion of the carboxy-terminal hydrophobic domain from the HE polypeptide resulted in secretion of a dimeric form of the truncated HE polypeptide. The acetylesterase activity of the BCV HE was detectable in insect cells expressing the BCV hemagglutinin and was inhibited by two monoclonal antibodies which also inhibit hemagglutination.
Intraventricular streptokinase after intraventricular hemorrhage in newborn infants (2001)

Intraventricular fibrinolytic therapy with streptokinase, given when post-hemorrhagic ventricular dilatation is established, cannot be recommended for neonates following IVH. A conservative approach with CSF drainage applied only to symptomatic raised intracranial pressure seems appropriate.
Tracer kinetic modelling in MRI: estimating perfusion and capillary permeability (2011)

The tracer-kinetic models developed in the early 1990s for dynamic contrast-enhanced MRI (DCE-MRI) have since become a standard in numerous applications. At the same time, the development of MRI hardware has led to increases in image quality and temporal resolution that reveal the limitations of the early models. This in turn has stimulated an interest in the development and application of a second generation of modelling approaches. They are designed to overcome these limitations and produce additional and more accurate information on tissue status. In particular, models of the second generation enable separate estimates of perfusion and capillary permeability rather than a single parameter K(trans) that represents a combination of the two. A variety of such models has been proposed in the literature, and development in the field has been constrained by a lack of transparency regarding terminology, notations and physiological assumptions. In this review, we provide an overview of these models in a manner that is both physically intuitive and mathematically rigourous. All are derived from common first principles, using concepts and notations from general tracer-kinetic theory. Explicit links to their historical origins are included to allow for a transfer of experience obtained in other fields (PET, SPECT, CT). A classification is presented that reveals the links between all models, and with the models of the first generation. Detailed formulae for all solutions are provided to facilitate implementation. Our aim is to encourage the application of these tools to DCE-MRI by offering researchers a clearer understanding of their assumptions and requirements.
Phase Transitions, Solubility, and Crystallization Kinetics of Phytosterols and Phytosterol−Oil Blends (2007)

The thermal properties, solubility characteristics, and crystallization kinetics of four commercial phytosterol preparations (soy and wood sterols and stanols) and their blends with corn oil were examined. Differential scanning calorimetry (DSC) revealed narrow melting peaks between 138 and 145 degrees C for all phytosterol samples, reversible on rescan. Broader and less symmetrical melting transitions at lower temperatures with increasing oil content were observed for two samples of phytosterol-oil admixtures. The estimated, from the solubility law, deltaH values (34.7 and 70.7 mJ/mg for wood sterols and stanols, respectively), were similar to the DSC experimental data. Fatty acid esters of soy stanols differing in the chain length of the acyl groups (C2-C12) exhibited suppression of the melting point and increase of the fusion enthalpy with increasing chain length of the acyl group; the propionate ester exhibited the highest melting point (Tm: 151 degrees C) among all stanol-fatty acid esters. Solubility of phytosterols in corn oil was low (2-3% w/w at 25 degrees C) and increased slightly with a temperature rise. Plant sterols appeared more soluble than stanols with higher critical concentrations at saturation. The induction time for recrystallization of sterol-oil liquid blends, as determined by spectrophotometry, depended on the supersaturation ratio. The calculated interfacial free energies between crystalline sediments and oil were smaller for sterol samples (3.80 and 3.85 mJ/m2) than stanol mixtures (5.95 and 6.07 mJ/m2), in accord with the higher solubility of the sterol crystals in corn oil. The XRD patterns and light microscopy revealed some differences in the characteristics among the native and recrystallized in oil phytosterol preparations.
Antigen-specific T cell-mediated suppression. II. In vitro induction by I-J-coded L-glutamic acid50-L-tyrosine50 (GT)-specific T cell suppressor factor (GT-T8F) of suppressor T cells (T82) bearing distinct I-J determinants. (1978)

The induction of new suppressor T cells (Ts2) by suppressive extracts (TsF) from L-glutamic acid50L-tyrosine50 (GT) nonresponder mice was examined. Incubation of normal spleen cells with allogeneic GT-TsF for 2 days in vitro led to the generation of Ts2 cells able to suppress subsequent responses to the immunogen GT-methylated bovine serum albumin (GT-MBSA) in vivo. This induction occurred efficiently when TsF donor and target cells differed at all of H-2, including the I-J subregion. B10.BR (H-2k) GT-TsF, adsorbed on, then acid eluted from GT-Sepharose and anti-I-Jk [B10.A (3R) anti-B10.A (5R)]-Sepharose in a sequential fashion could induce BALB/c (H-2d) spleen cells to become Ts2 only if nanogram quantities of GT were added to the purified GT-TsF. This indicates a requirement for a molecule or molecular complex possessing both I-J determinants and antigen (GT)-binding specificity, together with GT itself, for Ts2 induction. The induced Ts2 are I-J+, since their function can be eliminated by treatment with anti-I-Jk plus C. These I-J determinants are coded for by the precursor of the Ts2 and do not represent passively adsorbed, I-J coded TsF, since anti-Ijk antiserum [(3R X DBA/2)F1 anti-5R] which cannot recognize the BALB/c (I-Jd) TsF used for induction still eliminates the activity of induced A/J (I-Jk) Ts2. These data provide further evidence for and information about the minimum of two T cells involved in antigen-specific suppressor T cell systems.
Railgun barrel design and analysis (1984)

For various reasons, contemporary barrel designs for railguns have tended to be somewhat bulky. Ultimately, the more demanding missions expected of railguns than their conventional chemical counterparts pose a special technical problem for the railgun designer in his attempt to minimize weight and maximize launch efficiency, both of which are crucial in many applications currently contemplated for railguns. The key to achieving the dual goals of weight minimization and efficiency maximization lies in the efficient control of the coupled transient electromagnetic, thermal and mechanical effects against the constraints of realizable material properties. These effects frequently place converse geometric constraints on the design. In a recent design study undertaken by Westinghouse, a barrel concept based on an oval geometry for the barrel cross section and an electromagnetically and structurally shaped geometry for the rails is identified as having the greatest potential in attaining this dual goal, especially for solid-armature driven railguns. To facilitate future design efforts, a design methology is presented which is based on a wide spectrum of computational tools for analyzing the multifaceted barrel performance. The iterations between the design-and-analysis cycles are a crucial interplay for railgun barrel development.
Optimization of a Commercially Available Chemiluminscence Analyzer for Low Level NOx Measurement (2003)

<div class="htmlview paragraph">As automotive exhaust emission levels reduce, there is a need for increased sensitivity of the NOx measurement. This paper documents work performed to increase the sensitivity of the existing Rosemount NGA 2000 CLD Analyzer. The effects of sample flow rate, ozone flow rate and ozone supply gas were explored. Limit of Detection (LOD) and Converter Efficiency were evaluated. The goal of this optimization has been to provide a cost effective and expeditious method to improve the low level NOx measurement. Changing the ozone generator supply gas from air to oxygen and increasing the sample and ozone flow rates resulted in a LOD improvement from 17 ppb to 8 ppb.</div>

Sonofragmentation: Effect of Ultrasound Frequency and Power on Particle Breakage (2016)

This paper investigates, for the first time, the breaking mechanism of particles exposed to implosions of stable and transient cavitation bubbles via Kapur function analysis. The effect of ultrasonic frequencies of 30–1140 kHz and powers of 4–200 W on particle breakage of paracetamol crystals was studied. The dominant cavitation bubble type was defined via sonoluminescence measurements. The breakage rate of seed crystals with a median size of 75 μm was found to be independent of the applied power when ultrasonically generated stable cavitation bubbles were generated. Furthermore, a particle size threshold of ca. 35 μm was observed. The particle size could not be reduced below this size regardless of the applied power or frequency. For transient bubbles, in contrast, higher powers lead to considerably smaller particles, with no threshold size within the investigated power range. The Kapur function analysis suggests that stable bubbles are more efficient than transient bubbles to break coarse particles with sizes above 40 μm. Finally, cumulative breakage functions were calculated, and it was observed that transient bubbles generate more abrasion than stable bubbles.
