Design Considerations for a Multiple-Reactor DEMON Process Treating Sludge Liquors from a Thermal Hydrolysis Anaerobic Digester (2013)

Design Considerations for a Multiple-Reactor DEMON Process Treating Sludge Liquors from a Thermal Hydrolysis Anaerobic DigesterThe DEMON treatment process is rapidly becoming an established technology for sidestream treatment due to its low energy use and no requirement for carbon addition to remove nitrogen completely through deammonification. A new filtrate treatment facility (FTF) based on the DEMON process and currently under design for the Blue Plains Advanced Wastewater Treatment Plant (AWTP) has several unique...Author(s)Andrew ShawPeter ThomsonBeverley StinsonSalil KharkarSudhir MurthyChris deBarbadilloNick PassarelliBernhard WettGeert NyhuisBlair WisdomSourceProceedings of the Water Environment FederationDocument typeConference PaperPublisherWater Environment FederationPrint publication date Jul, 2013ISSN1938-6478DOI10.2175/193864713813525428Volume / Issue2013 / 4Content sourceNutrient Removal and Recovery SymposiumCopyright2013Word count159
Integrating Vision Based Navigation with INS and GPS for Land Vehicle Navigation in Challenging GNSS Environments (2016)

The inertial navigation system (INS) and the global positioning systems (GPS) are the most popular methods of navigation. However, the INS is prone to severe drift errors, especially when dealing with commercial grade systems, and GPS may not always be available, such as indoors and in downtown canyons. This paper proposes a vision based navigation system with landmark matching to improve the overall navigation solution, particularly in the absence of GPS. Landmarks of known position need to be set in advance. As the landmark appears in the visual images, it is detected through a template matching algorithm, and the vehicle’s position and azimuth angle are determined, which are then fed to the extended Kalman filter (EKF) to integrate with the INS information. This method was applied to an indoor trajectory without GPS coverage and an outdoor portion in the presence of GPS, and the resulting solution was far more accurate when compared to an INS only solution.
Hodgkin lymphoma (2012)

Hodgkin lymphoma (HL), a B cell-derived cancer, is one of the most common lymphomas. In HL, the tumor cells--Hodgkin and Reed-Sternberg (HRS) cells--are usually very rare in the tissue. Although HRS cells are derived from mature B cells, they have largely lost their B cell phenotype and show a very unusual co-expression of markers of various hematopoietic cell types. HRS cells show deregulated activation of multiple signaling pathways and transcription factors. The activation of these pathways and factors is partly mediated through interactions of HRS cells with various other types of cells in the microenvironment, but also through genetic lesions. The transforming events involved in the pathogenesis of HL are only partly understood, but mutations affecting the NF-κB and JAK/STAT pathways are frequent. The dependency of HRS cells on microenvironmental interactions and deregulated signaling pathways may offer novel strategies for targeted therapies.

Superconducting critical fields of alkali and alkaline-earth intercalates of MoS2 (1976)

The critical-field anisotropy and temperature dependence of the alkali and alkaline-earth intercalates of Mo${\mathrm{S}}_{2}$ have been measured. There are three principal results: First, an unusual positive curvature in the critical-field-temperature boundary has been observed. This curvature appears to be a universal feature of layered superconductors and possible theoretical explanations are discussed. Secondly, the critical-field anisotropy is compared with two models, a coupled-layer model and an uncoupled-layer or thin-film model. Which model fits the data depends on the material, and it is apparent that very accurate experimental data must be taken to distinguish between the models. Our third principal result is the grouping of properties of the alkali and alkaline-earth series of intercalates. The materials with the largest ionic intercalate atom diameters and hexagonal structures (K, Rb, and Cs compounds) have the highest critical temperatures, critical fields, and critical boundary slopes. In all cases the hexagonal materials have critical fields exceeding the paramagnetic limiting fields. The second group, consisting of the nonhexagonal Na, Sr, and Ca intercalates, have lower critical temperatures and fields, and the paramagnetic limit is not exceeded.
Whole Body Motion Noise Cancellation of a Robot for Improved Automatic Speech Recognition (2011)

The motors of a robot produce ego-motion noise that degrades the quality of recorded sounds. This paper describes an architecture that enhances the capability of a robot to perform automatic speech recognition (ASR) even as the entire body of the robot moves. The architecture consists of three blocks: (i) a multichannel noise reduction block, consisting of microphone-array-based sound localization, geometric source separation and post-filtering, (ii) a single-channel template subtraction block and (iii) an ASR block. As the first step of our analysis strategy, we divided the whole-body motion noise problem into three subdomains of arm, leg and head motion noise, according to their intensity levels and spatial location. Subsequently, by following a synthesis-by-analysis approach, we determined the best method for suppressing each type of ego-motion noise. Finally, we proposed to utilize a control module in our ASR framework; this module was designed to make decisions based on instantaneously detected motions, allowing it to switch to the most appropriate method for the current type of noise. This proposed system resulted in improvements of up to 50 points in word correct rates compared with results obtained by single microphone recognition of arm, leg and head motions.
Burkholderia thailandensis harbors two identical rhl gene clusters responsible for the biosynthesis of rhamnolipids (2009)

Collectively, these results add another Burkholderia species to the list of bacteria able to produce rhamnolipids and this, by the means of two identical functional gene clusters. Our results also demonstrate the very impressive tensio-active properties these long-chain rhamnolipids possess in comparison to the well-studied short-chain ones from P. aeruginosa.
Characterization of the mechanical behavior of an electrically actuated microbeam (2002)

We present a nonlinear model of electrically actuated microbeams accounting for the electrostatic forcing of the air gap capacitor, the restoring force of the microbeam and the axial load applied to the microbeam. The boundary-value problem describing the static deflection of the microbeam under the electrostatic force due to a dc polarization voltage is solved numerically. The eigenvalue problem describing the vibration of the microbeam around its statically deflected position is solved numerically for the natural frequencies and mode shapes. Comparison of results generated by our model to the experimental results shows excellent agreement, thus verifying the model. Our results show that failure to account for mid-plane stretching in the microbeam restoring force leads to an underestimation of the stability limits. It also shows that the ratio of the width of the air gap to the microbeam thickness can be tuned to extend the domain of the linear relationship between the dc polarization voltage and the fundamental natural frequency. This fact and the ability of the nonlinear model to accurately predict the natural frequencies for any dc polarization voltage allow designers to use a wider range of dc polarization voltages in resonators.
Superresolution multispectral imaging polarimetric space surveillance LADAR sensor design architectures (2008)

This study consists of the exploitation of novel ladar design principles and architectures aimed at the increasing of the superresolution, and imaging capabilities of the space surveillance ladars for efficient detection, discrimination, and monitoring of space objects and man-made materials detection. Ladar interferometric techniques relying on Vertical- Cavity Surface-Emitting Laser (VCSEL) coherent arrays would provide enhanced lightweight imaging solutions, with unsurpassable dynamic range, at low power consumption, remarkable reliability, and reduced cost. The experimental results of this study indicate that the signal-to-noise ratio of backscattered optical signals can be enhanced significantly, by utilizing efficient single-pixel polarimetric techniques; as a result the ladar range accuracy would be improved significantly. In addition, several space materials and man-made materials are shown to exhibit distinct depolarization signatures which can be used to characterize, classify, and identify those materials.
Sensitivity to Binocular Disparity is Reduced by Mild Traumatic Brain Injury (2017)

Our results suggest that the reduced disparity sensitivity in patients with mTBI is more likely caused by cortical changes (e.g., axonal shearing, or reduced interhemispheric communication) rather than oculomotor dysfunction.
ADP receptor antagonists as antiplatelet therapeutics (2003)

With the cloning of the P2Y12 receptor, the molecular basis for ADP-induced platelet aggregation is seemingly complete. Two platelet-bound ADP receptors, P2Y1 and P2Y12, operate through unique pathways to induce and sustain platelet aggregation via the glycoprotein (GP)IIb-IIIa integrin. P2Y1 operates via a glycoprotein q (Gq) pathway, activates phospholipase C, induces platelet shape change and is responsible for intracellular calcium mobilisation. P2Y12 inhibits adenylyl cyclase through a glycoprotein i (Gi)-dependent pathway, and is the target of the clinically used thienopyridines, ticlopidine (Ticlid®, F. Hoffmann-La Roche) and clopidogrel (Plavix®, Bristol-Myers Squibb/Sanofi-Synthelabo). In addition, the receptor is targeted by the ADP analogue AR-C66096, which is currently in Phase IIb clinical trials, as well as other non-nucleoside-based preclinical leads.
Simulation of a Linear Generator for Wave Power Absorption -Part I : Modeling (2007)

This thesis is focused on development of models and modelling of a wave energy converter in operation. Through the thesis linear potential wave theory has been used to describe the wave-buoy interaction. The differences lie in the generator models, in the simplest model the generator is a mechanical damper characterized by a damping factor. In the most advanced generator model the magnetic fields is calculated the by a FE-method, which gives detailed description of the electric properties and the effect it has on the buoy dynamics. Moreover, an equivalent circuit description of the generator has been tested. It has the same accuracy as the field based model but with a strongly enhanced CPU time. All models are verified against full scale experiments. The models are intended to be used for design of the next generation wave energy converters. Further, the developed models have also been used to study what effect buoy geometry and generator damping have on the ability to energy absorption. In the spring 2006 a full scale wave energy converter was installed at the west coast of Sweden. It was in operation and collected data during three months. During that period the load resistance was varied in order to study the effect on the energy absorption. These collected data was then used in the verification of the developed models. In the year 2002 a wave energy project started at Uppsala University; this work is a part of that larger project which intendeds to develop a viable wave energy conversion concept.
Epoxidized linolenic acid salts as multifunctional additives for the thermal stability of plasticized PVC (2014)

ABSTRACT Calcium and zinc salts of epoxidized linolenic acid were synthesized and used as multifunctional additives, to minimize or prevent the reaction of epoxidized soybean oil (ESO) with liberated hydrochloric acid (HCl) during the thermal degradation of poly(vinyl chloride) (PVC) in particular. These metal epoxy salts were incorporated as thermal stabilizers for both diisodecyl phthalate and ESO–plasticized PVC blends that underwent thermal degradation studies at 170°C. The overall performance of these metal epoxy salts was examined by thermal gravimetric analysis and visual color retention of the PVC blends. The weight loss profiles of the metal salt stabilized PVC were comparable to those of blends containing metal stearates. There were, however, vast improvements in color retention of the plasticized PVC using these novel additives. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015 , 132 , 41736.
The Monge-Ampère equation design method and its application to beam shaping (2015)

C-8 | Analysis of Impella for Treatment of Acute Myocardial Infarction and Cardiogenic Shock: Outcomes of the RECOVER III Post-Approval Study by SCAI Shock Stage (2023)

Recently, the Society of Cardiovascular Angiography and Interventions (SCAI) proposed an alphabetical staging system (A-E) to predict prognosis in cardiogenic shock. Herein, we report clinical outcomes of patients enrolled in RECOVER III, highlighting the impact of the SCAI Shock Stage on outcomes. The RECOVER III study is an observational, prospective, multicenter, single-arm, FDA-audited post-approval study of patients with acute myocardial infarction complicated by cardiogenic shock (AMICS) at 41 sites undergoing percutaneous coronary intervention (PCI) with Impella support initiated before, during, or after PCI. Presence of an Impella device was required for enrollment in RECOVER III, otherwise management of CS was left to the discretion of individual sites. Patients enrolled in RECOVER III were assigned a baseline SCAI shock stage by consensus agreement between blinded observers. Staging was then repeated within 24 hours of Impella support. Kaplan Meier survival curve analyses were conducted to assess survival across SCAI shock stages at both time points. A total of 413 RECOVER III patients were considered eligible and included in the analysis. All patients were at least stage C due to presence of an Impella device. Thirty-day survival amongst patients with Stage C, D and E shock at baseline was 59.7%, 56.5% and 42.9%, respectively (p=0.003). Survival amongst patients with Stage C, D and E shock at 24 hours was 65.7%, 52.1% and 29.5%, respectively (p<0.001). After multivariate analysis of shock stage, only stage E at 24 hours was a significant negative predictor of survival (OR 4.8 for mortality, p<0.0001). In this “real-world” cohort of patients with AMICS undergoing PCI with Impella support, survival was highly dependent on SCAI shock stage at baseline. Repeat shock stage assessment within 24 hours affords incremental prognostic value.

Search for lepton-flavor-violating decays of the Z boson into a τ lepton and a light lepton with the ATLAS detector (2018)

Direct searches for lepton flavor violation in decays of the $Z$ boson with the ATLAS detector at the LHC are presented. Decays of the $Z$ boson into an electron or muon and a hadronically decaying $\ensuremath{\tau}$ lepton are considered. The searches are based on a data sample of proton-proton collisions collected by the ATLAS detector in 2015 and 2016, corresponding to an integrated luminosity of $36.1\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ at a center-of-mass energy of $\sqrt{s}=13\text{ }\text{ }\mathrm{TeV}$. No statistically significant excess of events above the expected background is observed, and upper limits on the branching ratios of lepton-flavor-violating decays are set at the 95% confidence level: $\mathcal{B}(Z\ensuremath{\rightarrow}e\ensuremath{\tau})&lt;5.8\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$ and $\mathcal{B}(Z\ensuremath{\rightarrow}\ensuremath{\mu}\ensuremath{\tau})&lt;2.4\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$. This is the first limit on $\mathcal{B}(Z\ensuremath{\rightarrow}e\ensuremath{\tau})$ with ATLAS data. The upper limit on $\mathcal{B}(Z\ensuremath{\rightarrow}\ensuremath{\mu}\ensuremath{\tau})$ is combined with a previous ATLAS result based on $20.3\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of proton-proton collision data at a center-of-mass energy of $\sqrt{s}=8\text{ }\text{ }\mathrm{TeV}$ and the combined upper limit at 95% confidence level is $\mathcal{B}(Z\ensuremath{\rightarrow}\ensuremath{\mu}\ensuremath{\tau})&lt;1.3\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}5}$.
GE Electric Drivetrain Technologies for Lightweight Battery Dominant Hybrid Fuel Cell Bus (2012)

&lt;div class="section abstract"&gt;&lt;div class="htmlview paragraph"&gt;Aside from the fuel cell prime mover, the drivetrain elements of a fuel cell hybrid transit bus are those of a heavy-duty series hybrid vehicle. The U.S. National Fuel Cell Bus Program is advancing all aspects of fuel cell transit bus technology, including fuel cells and other electric drivetrain technologies. Key electric drivetrain technologies developed by General Electric (GE) in the Lightweight Battery-dominant Hybrid Fuel Cell Bus project, their integration to the vehicle design, together with the vehicle build and demonstration plans are described. The GE technologies are sodium metal halide energy batteries, the dual battery energy storage system, energy management controls and dc-dc converter power electronics. Further electric drive vehicle technology developments focused on the fuel cell transit bus application are proposed.&lt;/div&gt;&lt;/div&gt;
Multicarrier waveform processing for HF communications (2018)

High-frequency (HF) band communications can be flexibly realized using multicarrier modulation (MCM) techniques. HF channels are typically characterized by severe multi-path effects and high Doppler spreads requiring advanced estimation and equalization methods as well as elaborate waveform design for addressing these issues. This paper compares the performance of three widely utilized MCM techniques, namely, cyclic prefix (CP) orthogonal frequency-division multiplexing (OFDM), filter bank multicarrier/offset-QAM (FBMC/OQAM), and filtered multitone (FMT) in HF communications. In addition, the filtered variant of CP-OFDM is included in the comparison. The performance of these systems is simulated using commonly adopted HF-channel models. Channel estimation is carried out using scattered pilots with minimum mean-squared error based interpolation schemes whereas the equalization is realized using frequency-sampling based subcarrier equalizer. It is shown that the simulated uncoded bit-error rate of CP-OFDM is superior when compared with FBMC/OQAM and FMT even in the case when CP-OFDM waveform is filtered for better spectral containment. In addition, the implementation complexity and peak-to-average power ratio performance of (filtered) CP-OFDM compare favourable with FBMC/OQAM and FMT.
Closure of a persistent esophagopleural fistula assisted by a novel endoscopic suturing system (2012)

Gastrointestinal fistulas may be successfully managed endoscopically [1]. Novel endoscopic techniques for full thickness tissue approximation may serve as adjuvants for assisting fistula closure [2] [3]; an example is a flexible endoscopic suturing system [4]. We describe a case of a chronic esophageal fistula, treated previously with endoscopic clipping and esophageal stenting, which was successfully managed using a novel endoscopic suturing system [5].
Search for a heavy narrow resonance decaying to eμ eτ or μτ with the ATLAS detector in √s=7 TeV pp collisions at the LHC (2013)

This Letter presents the results of a search for a heavy particle decaying into an e^±μ^∓e^±μ^∓, or μ^±τ^∓ final state in pp collisions at View the MathML sources=7 TeV. The data were recorded with the ATLAS detector at the LHC during 2011 and correspond to an integrated luminosity of 4.6 fb−14.6 fb^(−1). No significant excess above the Standard Model expectation is observed, and exclusions at 95% confidence level are placed on the cross section times branching ratio for the production of an R-parity-violating supersymmetric tau sneutrino. For a sneutrino mass of 500 (2000) GeV, the observed limits on the production cross section times branching ratio are 3.2 (1.4) fb, 42 (17) fb, and 40 (18) fb for the eμ, eτ, and μτ modes, respectively. These results considerably extend constraints from Tevatron experiments.
Urogenital photoacoustic endoscope (2014)

Photoacoustic (PA) endoscopy for human urogenital imaging has the potential to diagnose many important diseases, such as endometrial and prostate cancers. We have specifically developed a 12.7 mm diameter, rigid, side-scanning PA endoscopic probe for such applications. The key features of this endoscope are the streamlined structure for smooth cavity introduction and the proximal actuation mechanism for fast scanning. Here we describe the probe's composition and scanning mechanism and present in vivo experimental results suggesting its potential for comprehensive clinical applications.
The Influence of Including a Partially Smooth Section in the 2nd Leg of an Internally Ribbed Two Pass Cooling Channel (2006)

Internal cooling schemes for blades in a gas turbine engine often are subject to compromises between increased pressure losses in return for greater levels of heat transfer required to maintain durability levels in the engine’s harsh environment. Rib configurations have been the subject of much study in past years, however these configurations are normally presumed to be used in “full-coverage” mode, meaning that the ribs are placed in the channel in a continuous and uniform manner. This study investigates the interaction between the bend effects downstream of a 180° bend, which cause higher local heat transfer, and the effect of ribs. Some of the ribs directly downstream of the 180° bend in the 2nd leg of a two pass high aspect ratio (4:1) channel were removed and the effect on heat transfer was assessed. Experimental results showed that the heat transfer level recovered quickly once ribs were encountered. As expected, some decrease in heat transfer was observed in the region where ribs were removed; however total pressure losses in the channel were also much lower. Results include detailed two-dimensional heat transfer distributions determined by the transient liquid crystal method as well as an analysis of the balance between pressure recovery and local heat transfer levels. Generally, for the accuracy of the transient liquid crystal technique in complex three-dimensional flows, strongly varying fluid temperatures present in and downstream of the bend region must be taken into account. For this study, time and position dependent fluid temperature distributions were measured to account for these effects, making it possible to obtain high quality heat transfer results in those regions.
