New-web search with microblog annotations (2010)

Web search engines discover indexable documents by recursively 'crawling' from a seed URL. Their rankings take into account link popularity. While this works well, it introduces biases towards older documents. Older documents are more likely to be the target of links, while new documents with few, or no, incoming links are unlikely to rank highly in search results.
Measurement of temporal frequency characteristics of VEP using pseudorandom binary sequence and their correlation with cerebral blood flow in human visual cortex (2002)

Steady-state visual evoked potentials (S-VEP) have been used to derive temporal frequency characteristics, which are effective in detecting sensitivity loss for high-frequency stimuli in early glaucoma. However, this method requires independent measurements of VEPs for various frequencies. In this study, an improved technique using pseudorandom binary sequence (PRBS) stimulation to elicit VEPs (PRBS-VEP) was proposed and compared with the S-VEP. Regional cerebral blood flow (CBF) was also measured with positron emission tomography (PET), and its response to stimulation was compared with the VEP. Results showed that PRBS-VEP yielded temporal frequency characteristics similar to those obtained by S-VEP, but in a much shorter time. Furthermore, CBF response in the primary visual cortex was well correlated with the VEP amplitude, suggesting that VEPs originate in the primary visual cortex.
Business Process Impact Visualization and Anomaly Detection (2006)

Business operations involve many factors and relationships and are modeled as complex business process workflows. The execution of these business processes generates vast volumes of complex data. The operational data are instances of the process flow, taking different paths through the process. The goal is to use the complex information to analyze and improve operations and to optimize the process flow. In this paper, we introduce a new visualization technique, called VisImpact that turns raw operational business data into valuable information. VisImpact reduces data complexity by analyzing operational data and abstracting the most critical factors, called impact factors, which influence business operations. The analysis may identify single nodes of the business flow graph as important factors but it may also determine aggregations of nodes to be important. Moreover, the analysis may find that single nodes have certain data values associated with them which have an influence on some business metrics or resource usage parameters. The impact factors are presented as nodes in a symmetric circular graph, providing insight into core business operations and relationships. A cause-effect mechanism is built in to determine ‘good’ and ‘bad’ operational behavior and to take action accordingly. We have applied VisImpact to real-world applications, fraud analysis and service contract analysis, to show the power of VisImpact for finding relationships among the most important impact factors and for immediate identification of anomalies. The VisImpact system provides a highly interactive interface including drilldown capabilities down to transaction levels to allow multilevel views of business dynamics.
High Frequency Plasma Enhancement of a Conventional Spark Ignition System to Extend the Operating Range of a Modern Mass-Production Engine (2018)

Das Erreichen künftiger Abgas- und Verbrauchsrichtlinien stellt bei der Entwicklung moderner Antriebsstränge eine zunehmend große Herausforderung dar. In der Vergangenheit wurde eine Vielzahl alternativer Zündsysteme vorgestellt, welche die konventionelle Transistor-Funkenzündung ersetzen oder erweitern sollten. Der robuste und einfache Aufbau, die geringe Anzahl an Bauteilen und der hohe maximale Energieeintrag in den Brennraum rechtfertigen dessen Einsatz jedoch bis heute. Die Firma Rosenberger Hochfrequenztechnik GmbH &amp; Co. KG arbeitet zusammen mit der Ruhr-Universität Bochum an einer Erweiterung dieses bewährten Zündkonzepts. Das konventionelle Funkenzündsystem wird hierfür beibehalten und lediglich um einen Pfad zur Einkopplung eines hochenergetischen, hochfrequenten (HF) Signals erweitert. Während des konventionell erzeugten Funkens entsteht zwischen den Elektroden der Zündkerze ein leitfähiger Kanal mit niedriger Impedanz. Da die Leistung der konventionellen Zündspule begrenzt ist, wird zusätzlich in diesen Kanal die Energie des HFSignals eingebracht. Dadurch entsteht eine steuerbare HF-Plasmaentladung zwischen den Elektroden mit einem deutlich größeren Plasmavolumen verglichen mit dem Funken. Sowohl die Dauer als auch die Leistung der HF-Plasmaentladung können beliebig eingestellt werden. Dadurch kann auch außerhalb der bisherigen Betriebsbereichen die für die Entflammung des Gemischs notwendige Energie bereitgestellt werden. Versuche an einem hochentwickelten Großserien-Motor (2017 EA 211 Evo model, Volkswagen AG) zeigten, dass so der Motorlauf in verschiedenen, zündkritischen Betriebspunkten sichergestellt werden konnte. Im Bereich des Leerlaufs konnte beispielsweise ein signifikanter Verbrauchsvorteil festgestellt werden. Bei einer Drehzahl von 1000 min-1, einem indizierten Mitteldruck (pmi) von 1 bar und einer zugehörigen Standardabweichung kleiner als 0.1 bar konnten 14 g/kWh durch den erweiterten Einsatz von interner Abgasrückführung eingespart werden. Neben den motorischen Ergebnissen wird der detaillierte Aufbau des Zündsystems sowie die für eine Analyse des Systems notwendige Messtechnik vorgestellt.
Nanosession: 2D Electron Systems ‐ Atomic Configurations (2012)

This chapter discusses the first-principles characterization of the structural and electronic properties of (SrTiO3)5/(SrRuO3)1 superlattices. The mechanism to create the two-dimensional electron gas (2DEG) is totally new and based on the difference in electronegativity between Ru and Ti. Experimental evidence for intermixing and an insulating behaviour was reported for the DyScO3 /SrTiO3 interface. A number of novel phenomena including 2DEGs, charge ordering, electronic and atomic reconstructions and metal insulator transitions have been observed at complex oxide interfaces. The chapter presents how a controlled variation of the cation-stoichiometry of STO thin films can be utilized to tailor the electronic properties of the LaAlO3 (LAO)/ SrTiO3 (STO)-interface. The discovery of 2DEG at the interface of the two band insulators LAO and STO above a critical overlayer thickness of three monolayers (ML) of LAO has triggered intense investigations of oxide heterostructures. Controlled Vocabulary Terms insulators; metal-insulator transition; stoichiometry; two-dimensional electron gas
Theories and measures of consciousness: An extended framework (2006)

A recent theoretical emphasis on complex interactions within neural systems underlying consciousness has been accompanied by proposals for the quantitative characterization of these interactions. In this article, we distinguish key aspects of consciousness that are amenable to quantitative measurement from those that are not. We carry out a formal analysis of the strengths and limitations of three quantitative measures of dynamical complexity in the neural systems underlying consciousness: neural complexity, information integration, and causal density. We find that no single measure fully captures the multidimensional complexity of these systems, and all of these measures have practical limitations. Our analysis suggests guidelines for the specification of alternative measures which, in combination, may improve the quantitative characterization of conscious neural systems. Given that some aspects of consciousness are likely to resist quantification altogether, we conclude that a satisfactory theory is likely to be one that combines both qualitative and quantitative elements.
A novel sorbitol transport mechanism in cultured renal papillary epithelial cells (1989)

The renal papillary epithelial cell line, GRB-PAP1, accumulates sorbitol when grown in a hypertonic (500 mosmol/kgH2O) bathing medium. When the cells are returned to a 300 mosmol/kgH2O medium, they lose their sorbitol rapidly to the bath. Sorbitol movement across the membranes of these cells was investigated by studying the uptake of radioactive sorbitol and related compounds. Sorbitol uptake increased 71-fold when cells grown in 500 mosmol/kgH2O medium were exposed to a 300 mosmol/kgH2O test solution. The magnitude of the permeability increase was proportional to the size of the change in the osmolality of the bathing medium and not the absolute osmolality. Sorbitol uptake was a linear function of medium sorbitol concentration with no sign of saturation at sorbitol concentrations up to 315 mM. Although the permeability of other polyols was increased when the osmolality was reduced, competition between sorbitol and related sugars and polyols could not be demonstrated. Both the increased sorbitol uptake after a decrease in medium osmolality and the decrease to control permeability after return to the original osmolality were complete within 30 s. A wide variety of transport inhibitors and ion substitutions failed to alter the magnitude of the sorbitol permeability increase. The most effective inhibitor was quinidine, 1 mM reducing sorbitol uptake by 73%. The sorbitol permeability increase could also be blocked by reducing the temperature to 0 degrees C. Nonspecific uptake of sorbitol, such as endocytosis, was shown to be of only minor significance. The large increase in sorbitol permeability and subsequent sorbitol efflux enables these cells to withstand large decreases in osmolality without excessive swelling and consequent damage. A similar compensatory mechanism may operate in vivo in the renal papilla during the onset of diuresis.

A 22-ng/$\surd$ Hz 17-mW Capacitive MEMS Accelerometer With Electrically Separated Mass Structure and Digital Noise- Reduction Techniques (2020)

A fully integrated micro-electromechanical system (MEMS) accelerometer with extremely low noise level (22 ng/√Hz) and sufficiently low power consumption (17 mW) for emerging applications (such as infrastructure monitoring and next-generation oil and gas exploration) was developed. By applying concurrent operations of detection and control (enabled by a unique MEMS element) and reducing servo-signal leakage and noise caused by an interaction of 1-bit quantization and asymmetric mass deformation in the digital domain, a ninefold-lower noise level is achieved in comparison with state-of-the-art low-noise low-power MEMS accelerometers. The MEMS element was fabricated on 6-in Si/SOI/Si bonding wafers, while the detection and driver integrated circuits were fabricated as interface circuits with the standard 0.13-μm complementary metal-oxide-semiconductor (CMOS) process and the high-voltage 0.35-μm CMOS process, respectively. The power consumption of the developed MEMS accelerometer is 17 mW from 1.4-, 1.8-, and 12-V supplies, and it has an input range of ±0.55 g and bandwidth of 400 Hz.
Calculation of Magnet Losses in Concentrated-Winding Permanent-Magnet Synchronous Machines Using a Computationally Efficient Finite-Element Method (conference proceeding) (2012)

The proposed hybrid method combines Computationally Efficient-Finite Element Analysis (CE-FEA) with a new analytical formulation for eddy-current losses in the permanent magnets (PMs) of sine-wave current regulated brushless synchronous motors. The CE-FEA only employs a reduced set of magnetostatic solutions yielding substantial reductions in the computational time as compared with conventional FEA. The 3D end effects and the effect of PWM switching harmonics are incorporated in the analytical calculations. The algorithms are applied to two fractional-slot concentrated-winding interior permanent magnet motors with different circumferential and axial PM block segmentation arrangements. The method is validated against 2D and 3D Time Stepping (TS) FEA.

A145 EFFICACY AND SAFETY OF UPADACITINIB MAINTENANCE THERAPY IN PATIENTS WITH MODERATELY TO SEVERELY ACTIVE ULCERATIVE COLITIS: RESULTS FROM A RANDOMIZED PHASE 3 STUDY (2022)

Abstract Background Upadacitinib (UPA), an oral selective and reversible JAK inhibitor, demonstrated significantly greater efficacy compared with placebo (PBO) for induction of remission in patients with moderately to severely active ulcerative colitis (UC) in two phase 3 induction trials. Aims Evaluate safety and efficacy of 52 weeks of UPA 15 mg QD (UPA15) and 30mg QD (UPA30) compared to placebo in patients achieving clinical response following UPA 45 mg treatment in the induction trials. Methods The primary analysis (n=451) evaluated efficacy and safety of UPA15 and UPA30 compared to PBO as maintenance therapy. The primary endpoint was clinical remission via adapted Mayo score at wk 52. Ranked secondary endpoints included endoscopic improvement, maintenance of clinical remission, corticosteroid-free clinical remission, maintenance of endoscopic improvement, endoscopic remission, maintenance of clinical response and Histologic-endoscopic mucosal improvement (HEMI). Results Baseline characteristics were similar between all treatment groups. Both UPA15 and UPA30 met the primary endpoint, and all secondary endpoints. Significantly greater percentages of patients receiving UPA15 and UPA30 vs. PBO achieved clinical remission (42.3% and 51.7%, vs. 12.1%), endoscopic improvement (48.7% and 61.6%, vs. 14.5%), maintenance of clinical remission (59.2% and 69.7%, vs. 22.2%), corticosteroid-free clinical remission (57.1% and 68.0%, vs. 22.2%), maintenance of endoscopic improvement (61.6% and 69.5%, vs. 18.9%), endoscopic remission, (24.2% and 25.9%, vs. 5.6%) and HEMI (34.8% and 49.3%, vs. 11.8%) (p&amp;lt;0.001 for all endpoints). UPA15 and UPA30 were both well-tolerated and no new safety signals were observed. Rates for serious adverse events (AEs) and AEs leading to treatment discontinuation were similar between UPA15 and UPA30 groups and lower compared to the PBO group. Most common AEs were nasopharyngitis and creatine phosphokinase elevation among UPA groups and UC exacerbation within the PBO group (30.2%). Herpes zoster was only reported in UPA groups (3.9%-4.1%). Similar rates of malignancy excluding NMSC were seen within all groups (0.7%-1.3%). MACE were only reported among patients receiving PBO (0.7%), while VTE were only found with UPA30 (1.3%). Conclusions In patients responding to UPA induction therapy, both UPA15 and UPA30 were safe and effective as maintenance treatment at 52 wk for all primary and secondary endpoints. Patients receiving UPA30 responded approximately 10% better for most endpoints compared to those receiving UPA15. Both doses were well-tolerated, with no new safety signals observed.

Pulse-Width and Focal-Volume Dependence of Laser-Induced Breakdown (1981)

The laser-induced breakdown fields at 1.06 μm of fused SiO2, single-crystal NaCl, and air were measured as a function of focal volume and laser pulse width while keeping all other parameters, including the specimen, constant. The laser pulse width was varied from 40 psec to 31 nsec, and the focal volume was varied by over two orders of magnitude. The dependence of the breakdown field for NaCl and SiO2 on the laser pulse width tp and the focal folume V was empirically determined to be EB = AV−1tp−1/4 + C and the dependence for air to be EB = (AV−1 + C) tp−1/4, where A and C are material-dependent constants. Current theories of laser-induced breakdown are carefully compared with these present measurements and are found to be inconsistent.
The Effect of Fine Channel & Collisional Mixing on Mist CVD Method (2008)

The mist CVD method, previously named as mist deposition or spray pyrolysis, is an environmental friendly and cost-effective technology for the deposition of thin oxide films. The mist CVD method features the liquid solution of constituent elements as source materials, which is atomized to form the mist of aerosol particles. The mists are then transferred by a carrier gas to the reaction area to the deposition of thin films. This does not need vacuum systems because it is operated at atmospheric conditions. Furthermore various material solutions are chosen for the source, including innocuous and nonpoisonous ones. Therefore, this method possesses advantages of safety, cost-effective, light load to the environment, harmless to the human, and multiplicity of applying to a lot of materials.In order to make smoother films on large substrates in this technology, it is important to obtain the uniform flow of mists and carrier gas. We have developed two kind of new methods. One of them is named as fine channel mist chemical vapor deposition (FCM-CVD) method which has a fine channel and collisional mixing to obtain uniform flow of mists and carrier gas. The other is named as linear source mist (LSM-) CVD method which is a technique for specializing in a continuous process. With using FCM-CVD, we fabricated ZnO thin films and succeed to obtain the homogeneous thin films on the 100mm square glass substrate whose deviation rate was ±0.45% at 40mm2.In this study, we report the effect of “fine channel” and “collisional mixing” on mist CVD method from view points of theorem, simulation, experience, and so on.
Self-healing mixed matrix membranes containing metal–organic frameworks (2022)

Mixed-matrix membranes (MMMs) provide a means to formulate metal-organic frameworks (MOFs) into processable films that can help to advance their use in various applications. Conventional MMMs are inherently susceptible to craze or tear upon exposure to impact, cutting, bending, or stretching, which can limit their intended service life and usage. Herein, a simple, efficient, and scalable <i>in situ</i> fabrication approach was used to prepare self-healing MMMs containing Zr(iv)-based MOFs. The ability of these MMMs to self-heal at room temperature is based on the reversible hydrolysis of boronic-ester conjugates. Thiol-ene 'photo-click' polymerization yielded robust MMMs with ∼30 wt% MOF loading and mechanical strength that varied based on the size of MOF particles. The MMMs could undergo repeated self-healing with good retention of mechanical strength. In addition, the MMMs were catalytically active toward the degradation of the chemical warfare agent (CWA) simulant dimethyl-4-nitrophenyl phosphate (DMNP) with no change in activity after two damage-healing cycles.
Time reversal imaging of noise sources inside a reverberant room (2004)

In a reverberant room, the multiple reflected echoes make imaging of acoustical random sources difficult. In this talk, we give an original solution based on Time Reversal Principles. Basically, in a first step, the acoustic field due to a noise source is recorded by a set of microphones. In a second step, all the recorded signals are time-reversed and re-emitted by loudspeakers that now replace the microphones. We observe a strong enhancement of the mean intensity around the initial source position. In a first part, we highlight the formal link between time-reversal of pulsed and noise sources in reverberant media. Especially we deduce that the signal to noise ratio depends only on the number of pairs of microphone/loud speaker for noise sources. Numerical simulations confirm these predictions. In a second part, we present experimental results performed in a 5*3*3=m and reverberant room. The intensity map of noise acoustic sources with a working bandpass of [100–3000] Hz has been performed. The same experiment has been carried out with two coherent or incoherent sources. Moreover, the frequency dependence of the resolution obtained with this technique is studied. Finally, we focus on the SNR with respect to the bandpass and central frequency.
