A New Extreme-HP/HT Viscometer for New Drilling-Fluid Challenges (2007)

Summary Growing demand for natural gas in North America is driving the exploration and production industry to look for new resources in previously unexplored areas, and the deep Gulf of Mexico (GOM) continental shelf is currently attracting substantial attention. Several current deep-shelf high-pressure/high-temperature (HP/HT) wells have anticipated bottomhole temperatures that significantly exceed the operating limits of existing measuring-while-drilling and logging-while-drilling (MWD/LWD) tools; therefore, down-hole annular-pressure measurements will not be available for pressure management. This leaves temperature and hydraulic models as the best, if not the only, source of downhole-pressure information for these wells. These models depend on accurate surface inputs and laboratory-measured fluid properties under downhole conditions. Unfortunately, these anticipated temperatures and pressures also exceed the operating limits of conventional HP/HT viscometers. This lack of measured fluid properties under these extreme conditions will severely limit the ability of hydraulic models to predict downhole pressures. A new extreme-HP/HT (XHP/HT) concentric-cylinder viscometer was designed and built to fill this important technology gap for GOM deep-shelf HP/HT wells. The instrument is capable of measuring typical drilling-fluid viscosities up to 600°F (316°C) and 40,000 psig (276.0 MPa) and is capable of accurate property measurements for drilling fluids containing ferromagnetic materials. Subsequent verification and validation proved that the new viscometer compares favorably to commercially available field viscometers and more-sophisticated laboratory rheometers and therefore lends itself to widespread industry use. This paper reviews the development of the instrument and associated automated control system and explores health, safety, and environment (HSE) issues related to testing drilling fluids at these extreme conditions. The paper also presents results of verification and validation testing on invert-emulsion drilling fluids.
Sonic Hedgehog Functions as a Mitogen During Bell Stage of Odontogenesis (2003)

Epithelial-mesenchymal interactions are required for tissue growth and gene expression patterns during odontogenesis. We showed previously that Sonic hedgehog (SHH) is detectable in both dental epithelium and mesenchyme, while Shh transcripts are present in dental epithelium only, suggesting that SHH functions as an autocrine signal in epithelium and a paracrine signal in mesenchyme. This hypothesis was tested here. We found by in situ hybridization that the SHH autocrine receptor Ptch-2 is indeed expressed in dental epithelium whereas the paracrine receptor Ptc is expressed in mesenchyme. Bovine bell stage tooth germs were microsurgically separated into epithelial and mesenchymal portions and the resulting tissue fragments were organ-cultured. In epithelium fragments cultured by themselves, gene expression of Shh and Gli-1 (a putative transcriptional mediator of hedgehog signaling) was significantly decreased in both inner dental epithelium and stratum intermedium layers; this was accompanied by a sharp drop in epithelial cell proliferation. However, in companion control tissue fragments containing both epithelium and mesenchyme, Shh and Gli-1 expression as well as cell proliferation were maintained. Treatment of dental epithelial or mesenchymal cell populations in monolayer cultures with exogenous recombinant SHH stimulated cell proliferation. Together, the data provide clear evidence that Shh is synthesized by dental epithelium, reaches the underlying mesenchyme, and appears to act as an autocrine mitogen for epithelial cells and a paracrine mitogen for mesenchymal cells, thus exerting crucial functions in tooth germ growth, morphogenesis, and tissue-tissue interactions of bell stage of odontogenesis.

2.9 - 8.4 GHz Filter Bank Using Stub-Loaded Multi-Mode Resonators (2014)

This paper consolidates the activity of design and fabrication of 2.9 - 4.32 GHz, 4.3 - 6.42 GHz, and 6.4 - 8.4 GHz filter bank. Novel compact microstrip bandpass filters with stub-loaded multi-mode resonators are proposed. Simulated results indicate that all the filters exhibit insertion losses less than 1.5 dB with passband ripples of 1 dB and sharp attenuations of above 40 dB in their stopbands. The maximums of input and output VSWRs are 1.742 and 1.734, respectively. Due to fabrication error, the initial measured passbands show frequency shifts and insertion losses in upper passbands deteriorate seriously. After tuning of the filter bank, measured results imply that the input and output VSWRs are found lower than 2.135 and 2.187, and the insertion loss in 1 dB bandwidth is less than 2.52 dB. Filter bank has a sharp skirt and out-of-band rejection levels approaching to 40 dB in all desired stopbands except at the frequencies near 2f0.
Judicial mediators: are they constitutionally valid? (2006)

Extract: The Attorney-General of Victoria has set the proverbial âcat amongst the pigeonsâ by suggesting that judicial mediators could be appointed in Victoria sooner rather than later. Judicial mediators have been operating in the Canadian provinces of British Columbia and Ontario for 10 years or more and mediation has been embraced by the judiciary, more widely under the descriptor âjudicial dispute resolutionâ (JDR), in other provinces of Canada for some time. However their appointment overseas has been the subject of controversy here in Australia, with some commentators believing that the appointment of judicial mediators blurs the line between the role of the courts as being purely for adjudication and the role of mediator as helping parties to seek a consensual solution to their dispute.
Biochemical Characterization of SFC-1, a Class A Carbapenem-Hydrolyzing β-Lactamase (2007)

The carbapenem-hydrolyzing beta-lactamase SFC-1 from Serratia fonticola UTAD54 was overexpressed in Escherichia coli, purified, and characterized. The enzyme exhibited an apparent molecular mass of 30.5 kDa, determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. SFC-1 hydrolyzes penicillins, cephalosporins, aztreonam, and carbapenems and is inhibited by clavulanic acid, sulbactam, and tazobactam.
Diet-induced changes in uncoupling proteins in obesity-prone and obesity-resistant strains of mice (1998)

Uncoupling protein 2 (UCP2) maps to a region on distal mouse chromosome 7 that has been linked to the phenotypes of obesity and type II diabetes. We recently reported that UCP2 expression is increased by high fat feeding in adipose tissue of the A/J strain of mice, which is resistant to the development of dietary obesity. More recently, a third UCP (UCP3) was identified, which is expressed largely in skeletal muscle and brown adipose tissue. The UCP2 and UCP3 genes are located adjacent to one another on mouse chromosome 7. Thus, the roles of these UCPs in both metabolic efficiency and the linkage to obesity and diabetes syndromes is unclear. For this reason, we examined the expression of UCP2 and UCP3 in white adipose tissue and interscapular brown adipose tissue and in gastrocnemius/soleus muscle preparations from the obesity-resistant A/J and C57BL/KsJ (KsJ) strains and the obesity-prone C57BL/6J (B6) mouse strain. In both KsJ and A/J mice, UCP2 expression in white fat was increased approximately 2-fold in response to 2 weeks of a high fat diet, but there was no effect of diet on UCP2 levels in B6 mice. In skeletal muscle and in brown fat, neither UCP2 nor UCP3 expression was affected by diet in A/J, B6, or KsJ mice. However, in brown fat, we observed a 2-3-fold increase in the expression of UCP1 in response to dietary fat challenge, which may be related to diet-induced elevations in plasma leptin levels. Together, these results indicate that the consumption of a high fat diet selectively regulates UCP2 expression in white fat and UCP1 expression in brown fat and that resistance to obesity is correlated with this early, selective induction of UCP1 and UCP2 and is not associated with changes in expression of UCP3.
Evaluating two approaches for browser-based real-time multimedia communication (2012)

This paper introduces a novel approach on how to integrate real-time multimedia communication into web applications. By using a Javascript API any web developer has the tools to use telecommunication functionalities in web apps. We aimed for an easy and efficient solution for developers and have performed an expert evaluation comparing our approach with the recent WebRTC/RTCWeb initiative driven by the W3C and the IETF. Our results indicate that our approach is well received among web developers and has advantages over similar solutions in terms of easiness, cross-domain availability, and compatibility with telco services.

Spatial compounding for 2D strain estimation in the mouse heart: A pilot study (2010)

Abstract-Estimating cardiac strain in the mouse in the lateral direction using speckle tracking with adapted clinical equipment was shown to be challenging due to the fast heart rate and the large speckle size relative to the wall thickness. Compounding axial motion estimates acquired from different insonation angles can potentially improve lateral strain estimates. Therefore, the aim of this study was to test the feasibility of this methodology in the murine heart based on simulated data sets. A 3D kinematic model of a murine left ventricle was simulated and filled randomly with scatterers. Ultrasound short-axis images (10mm × 6mm) were obtained by assuming a linear array transducer. Beam steering was simulated at 3 different angles (22°, 0°, -22°). Axial motion was estimated in each data set by ID cross-correlation. A dynamic programming approach was integrated in the motion estimation algorithm to avoid discontinuities. Axial components were combined to reconstruct the in-plane motion vector. The 2D displacement fields were subsequently accumulated over the whole cycle. The procedure was repeated for 10 different distributions of scatterers to acquire 10 different RF data sets (5 for parameter tuning and 5 for comparing the methods). Radial and circumferential RMS strain errors calculated from the accumulated motion fields were compared with those obtained with 2D speckle tracking. Spatial compounding yielded significantly better radial (RMSE: 0.0737 ± 0.0078 vs. 0.112 ± 0.0094) as well as circumferential strain (RMSE: 0.102 ± 0.0097 vs. 0.281 ± 0.054).
Disclosure-Limited Data Dissemination (1986)

Abstract Statistical agencies use a variety of disclosure control policies with ad hoc justification in disseminating data. The issues involved are clarified here by showing that several of these policies are special cases of a general disclosure-limiting (DL) approach based on predictive distributions and uncertainty functions. A user's information posture regarding a target is represented by one predictive distribution before data release and another predictive distribution after data release. A user's lack of knowledge about the target at any time is measured by an uncertainty function applied either to the current predictive distribution or to the current predictive distribution and the previously held predictive distribution. Common disclosure control policies, such as requiring released cell relative frequencies to be bounded away from both zero and one, are shown to be equivalent to disclosure rules that allow data release only if specific uncertainty functions at particular predictive distributions exceed a limit. Data transformations, such as aggregation and cell suppression, that are intended to reduce the extent of disclosure are analyzed in simple but realistic scenarios.
Van Verkeersbordendatabank naar ITS-toepassingen: of van ondersteuning van de bestuurder naar een basis voor autonoom rijdende voertuigen (2016)

SamenvattingDe communicatievorm voor de weggebruiker zijn voornamelijk de verkeersborden.In Vlaanderen hebben we meer dan 1,6 miljoen verkeersborden zodat dit grote aantal niet direct een evidente communicatievorm is.Wanneer men de data van de verkeersborden naar het voertuig kan brengen, kan niet alleen de communicatie verbeteren maar zou dit ook kunnen gebruikt worden om de weggebruiker te ondersteunen.Het overbrengen van deze informatie naar het voertuig heeft de mogelijkheid om de complexe bestuurderstaak te verlichten en hierdoor bij te dragen tot een grotere verkeersveilighheid.Tevens vormt het overbrengen van de verkeersbordendata een basiselement om zelfrijdende voertuigen mogelijk te maken.Om de data van de verkeersbordendatabank bruikbaar te maken voor het voertuig moet deze eerst worden omgezet naar ITS-data.In Vlaanderen is een verkeersbordendatabank aanwezig die beperkt wordt gepdatet.In deze paper wordt onderzocht in welke mate andere tools kunnen ontwikkeld worden om het updaten van de data mogelijk te maken maar vooral ook om deze data via een model automatisch of semi-automatisch om te zetten naar ITS-data Er wordt onderzocht of bestaande RSI in voertuigen en/of bijkomende video-camera's kunnen aangewend worden om het up-to-date houden van data mogelijk te maken. 1 We maken hier dan nog abstractie van het juridisch en het verkeersregelend aspect van verkeersborden. 2VEBIMOBE: Verkeersbordendatabank Intelligente MobiliteitsBegeleiding 3 DE MOL, J., VLASSENROOT, S., KEPPENS, M., Een haalbaarheidstudie voor een snelheidskaart voor Vlaanderen, Colloquium Vervoersplanogisch Speurwerk De Xpert-Factor, Colloquium Ver
Wireless integrated circuit for the acquisition of electrocorticogram signals (2010)

We present the design and characterization of amplifiers and control logic for an integrated circuit designed to record electrocorticograms (ECoG) from the surface of the brain. The chip, which was fabricated in a 0.6-μm BiCMOS process, contains 100 amplifiers, control logic, and circuits for wireless power and transmission of data. ECoG signals, sensed by electrodes, are capacitively coupled to the amplifiers. Each amplifier has a gain of 59.2 dB, a maximum bandwidth of 240 Hz, an input referred noise of 2.8μV, and consumes 4.5μW of power. The output of each amplifier is connected to a 10-bit ADC via an adaptive-bias buffer and transmission gate whose transparency is set by the control logic. The control logic time-shares the ADC by multiplexing through one of five preset patterns of 32 on-chip signals. The digitized waveforms are then broadcasted wirelessly using a 900 MHz FSK transmitter. The entire chip consumes 7.2 mW of power during operation.
ADENOSINETRIPHOSPHATASE AND NUCLEOTIDE METABOLISM IN SYNAPTOSOMES OF RAT BRAIN1 (1970)

Abstract —In the presence of synaptosomes prepared from rat brain, only ATP, dATP and ADP but not dADP were active as substrates of phosphatase (ATP phosphohydrolase; EC 3.6.1 4) in the presence of 150mm‐Na + and 20mm‐K + . An active adenylate kinase (ATP:AMP phosphotransferase; EC 2.7.4.3.) was demonstrated in the synaptosomal fractions by means of paper chromatography, paper electrophoresis and enzymic reactions, so that the high activity with ADP as substrate could represent an activity of an ATPase. Apparently dADP was not a substrate for the kinase; no dATP was formed when dADP was incubated with the synaptosomal fraction in the presence of Na + , K + and Mg 2+ . Small amounts of P 1 were liberated with dADP, IDP, GDP or CDP, but not UDP, as substrates, but none was produced in the presence of mononucleotides. The adenine‐deoxyribose bond, but not the adenine‐ribose bond, was hydrolysed upon the addition of 5% (w/v) TCA to the reaction mixture. The K M for the hydrolysis of ATP but not ITP, in the presence of Mg 2+ , or of Na + , K + and Mg 2+ , was lower for the synaptosomal ATPase than for the microsomal ATPase, and the values for V max for synaptosomal ATPase were higher. The activation increment was generally higher for the synaptosomal ATPase and no distinct differences in the properties of the enzyme from either particulate fractions were observed. Mg 2+ could be partially replaced by Mn 2+ in the synaptosomal ATPase system, but there was little Na + ‐K + ‐activation observed in the presence of the latter. The effects of ouabain and of homogenization under various conditions suggested localization of the K + ‐sensitive site of the ATPase on the surface of the synaptosomal membrane. Activity of the Na + ‐K + ‐Mg 2+ ATPase increased after freezing and thawing of the sonicated, sucrose or tris‐treated preparations but decreased considerably in the synaptosomes treated with 001 m‐deoxycholate. Activity of the Mg 2+ ATPase in the latter preparation showed little change.
Cytotoxic and Antimalarial Prenylated Xanthones from Cratoxylum cochinchinense (2006)

A new prenylated xanthone, 5-O-methylcelebixanthone (1), together with six known compounds; celebixanthone (2), 1,3,7-trihydroxy-2,4-di(3-methylbut-2-enyl)xanthone (3), cochinchinone A (4), alpha-mangostin (5), beta-mangostin (6) and cochinchinone C (7) were isolated from roots of Cratoxylum cochinchinense. Their structures were elucidated by spectroscopic methods. Compounds 2 and 4-7 showed cytotoxic activity against the human lung cancer cell line (NCI-H187) with IC(50) values ranging from 0.65 to 5.2 microg/ml. Compounds 1, 2, 6 and 7 also showed antimalarial activity against Plasmodium falciparum with IC(50) values of 3.2, 4.9, 7.2 and 2.6 microg/ml, respectively.
Electro-Deposition of Thin Si and Ge Films Based on Ballistic Hot Electron Injection (2014)

An alternative wet deposition process of thin group-IV films is demonstrated under the hot electron injection into solutions. A nanocrystalline silicon (nc-Si) device, composed of a thin Au/Ti film, an anodized nc-Si layer, and an n+-Si substrate, operates as a surface-emitting cold cathode in SiCl4 and GeCl4 solutions. When the nc-Si emitter is driven alone without using any counter electrodes, thin Si and Ge films are deposited on the emitting surface with neither byproducts nor contaminations. The specific features of this deposition mode are discussed in comparison with the conventional dry process.
Photonic higher-order topological states induced by long-range interactions (2020)

we demonstrate 2D photonic HOTI (PHOTI) with topological states two dimensions lower than the one of the host system. We consider a photonic metacrystal of distorted Kagome lattice geometry that exhibits topological bulk polarization, leading to the emergence of 1D topological edge states and of higher order 0D states confined to the corners of the structure. Interestingly, in addition to corner states due to the nearest neighbour interactions and protected by generalized chiral symmetry 1, we discover and take advantage of a new class of topological corner states sustained by long-range interactions, available in wave-based systems, such as in photonics. Our findings demonstrate that photonic HOTIs possess richer physics compared to their condensed matter counterparts, offering opportunities for engineering novel designer electromagnetic states with unique topological robustness.
Getting Closer to MIMO Capacity with Non-Binary Codes and Spatial Multiplexing (2010)

In this paper, we discuss the combination of non-binary channel coding with higher-order modulation and MIMO transmission in the form of spatial multiplexing. In addition to the benefits of non-binary LDPC codes on the AWGN channel, we identify an inherent advantage for non-binary coding in multiple antenna schemes. By comparing binary and q-ary information processing at the receiver, we highlight the intrinsic advantages of non-binary coding. A performance comparison based on simulation results shows that, at similar system complexity, non-binary information processing can actually outperform the Shannon limit of its binary counterpart.

The Effects of Fluency Enhancing Conditions on Sensorimotor Control of Speech in Typically Fluent Speakers: An EEG Mu Rhythm Study (2018)

<b>Objective</b>: To determine whether changes in sensorimotor control resulting from speaking conditions that induce fluency in people who stutter (PWS) can be measured using electroencephalographic (EEG) mu rhythms in neurotypical speakers. <b>Methods</b>: Non-stuttering (NS) adults spoke in one control condition (solo speaking) and four experimental conditions (choral speech, delayed auditory feedback (DAF), prolonged speech and pseudostuttering). Independent component analysis (ICA) was used to identify sensorimotor μ components from EEG recordings. Time-frequency analyses measured μ-alpha (8-13 Hz) and μ-beta (15-25 Hz) event-related synchronization (ERS) and desynchronization (ERD) during each speech condition. <b>Results</b>: 19/24 participants contributed μ components. Relative to the control condition, the choral and DAF conditions elicited increases in μ-alpha ERD in the right hemisphere. In the pseudostuttering condition, increases in μ-beta ERD were observed in the left hemisphere. No differences were present between the prolonged speech and control conditions. <b>Conclusions</b>: Differences observed in the experimental conditions are thought to reflect sensorimotor control changes. Increases in right hemisphere μ-alpha ERD likely reflect increased reliance on auditory information, including auditory feedback, during the choral and DAF conditions. In the left hemisphere, increases in μ-beta ERD during pseudostuttering may have resulted from the different movement characteristics of this task compared with the solo speaking task. Relationships to findings in stuttering are discussed. <b>Significance</b>: Changes in sensorimotor control related feedforward and feedback control in fluency-enhancing speech manipulations can be measured using time-frequency decompositions of EEG μ rhythms in neurotypical speakers. This quiet, non-invasive, and temporally sensitive technique may be applied to learn more about normal sensorimotor control and fluency enhancement in PWS.
