Effects of the Confined Synthesis on Conjugated Polymer Transport Properties (2004)

Previous studies on conjugated polymer nanotubules, prepared by the template method, established that improvements in the molecular and supermolecular structure are responsible for the increase in the room temperature conductivity when the diameter decreases. Our study clearly indicates that a more complex situation can result from the confined synthesis of conjugated polymers in nanopores of a template. Nanowires of poly(3,4-ethylenedioxythiophene), a polythiophene derivative, have been prepared by electrochemical synthesis in polycarbonate templates with diameters ranging between 35 and 200 nm. The electrical transport study (down to 1.5 K) shows that the smaller the nanowire diameter, the stronger the insulating behavior. The temperature dependence of the sample resistance ranges between two extremes, a nonthermally activated regime for the PEDOT film close to the metal−insulator transition and a 2D Mott-variable range hopping-like regime for 35-nm nanowires. It is partly related to the doping level, deduced from X-ray photoelectron spectroscopy (XPS) measurements, which is reduced by about a factor of 2 for 35-nm nanowires, in comparison with the film. But this reduced doping level cannot account for the whole electrical effect. Another important result is the evidence of a decrease in the spin/charge ratio when the nanowire diameter goes from 100 to 50 nm as shown by electron spin resonance (ESR). It suggests that the polaron/bipolaron population ratio is modified. This result will also have important consequences for the transport mechanism.

Three-Terminal Common-Mode EMI Model for EMI Generation, Propagation, and Mitigation in a Full-SiC Three-Phase UPS Module (2018)

With superior loss characteristics, wide bandgap devices such as silicon carbide (SiC) mosfets are expected to replace Si-IGBTs in grid-connected applications. Uninterruptible power supply (UPS) is an application in which low conduction-loss and switching-loss from SiC devices can largely improve the system efficiency. However, fast switching of an SiC mosfet worsens the electromagnetic interference (EMI). In addition, the UPS is comprised of multiple converters wherein different combinations of the converters take part in power-transfer depending on the mode of operation. This complicates the prediction and strategies for noise, especially the common-mode (CM) part. Such complexity calls for deliberate strategies to be set before prototyping to contain and mitigate the CM noise. In this paper, a three-terminal CM circuit model is presented for a three-phase UPS with an active battery charger and a battery rack. The significance of a dc-dc converter on CM EMI generation and propagation has been analyzed based on the model. In a mode of operation where the dc-dc converter is active, a considerable amount of the CM noise is generated from the dc-dc converter. Also, the multiple resonances on the propagation path associated with dc inductors and the battery rack highly deteriorates CM EMI. As a mitigation strategy in the design phase, different topologies and pulsewidth modulation schemes for the ac-ac stage and the dc-dc stage have been compared based on the model. A 20-kW full-SiC UPS has been built and tested to experimentally verify the impact of the dc-dc converter operation on the noise and to validate the mitigation strategy.
Visual attention allocation between robotic arm and environmental process control (2015)

Fifty six participants time shared a spacecraft environmental control system task with a realistic space robotic arm control task in either a manual or highly automated version, The former could suffer minor failures, whose diagnosis and repair were supported by a decision aid. At the end of the experiment this decision aid unexpectedly failed. We measured visual attention allocation and switching between the two tasks, in each of the eight conditions formed by manual-automated arm X expected-unexpected failure X monitoring- failure management. We also used our multi-attribute task switching model, based on task attributes of priority interest, difficulty and salience that were self-rated by participants, to predict allocation. An unweighted model based on attributes of difficulty, interest and salience accounted for 96% of the task allocation variance across the 8 different conditions. Task difficulty served as an attractor, with more difficult tasks increasing the tendency to stay on task.
Molecular motion in nanocomposites of poly(ethylene oxide) and montmorillonite (2001)

Motion of chains of poly(ethylene oxide) within the interlayer spacing of 2:1 phyllosilicate/montmorillonite was studied with 1H and 13C NMR spectroscopy. Measurements of the 1H NMR line widths and relaxation times across a large temperature range were used to determine the effect of bulk thermal transitions on polymer chain motion within the nanocomposites. The results were consistent with previous reports of low apparent activation energies of motion. Details of the frequency and geometry of motion were obtained from a comparison of the 13C cross-polarity/magic-angle spinning spectra and relaxation times of the nanocomposite with those of the pure polymer. © 2001 John Wiley & Sons, Inc.

Skin biopsy rates and incidence of melanoma: population based ecological study (2005)

The incidence of melanoma is associated with biopsy rates. That the extra cases diagnosed were confined to early stage cancer while mortality remained stable suggests overdiagnosis-the increased incidence being largely the result of increased diagnostic scrutiny and not an increase in the incidence of disease.
A Framework for Policies over Provenance. (2011)

Provenance captures the history of a data item. This ensures the quality, the trustworthiness and the correctness of shared information, but the provenance may contain sensitive information so we may need to hide it. Sometimes we need access control policies to protect sensitive components and allow access based on certain properties. In other cases, we may need to share provenance but use redaction policies to circumvent the release of sensitive information. In this paper, we formulate an automatic procedure over provenance by combining these policies in an unified framework.
Sulfide Formation And Its Impacts On A Developing Country: A Case Study In Maputo, Mozambique (2014)

Wastewater undergoes physical, chemical and biological changes while flowing along sewer systems. For the past decades, awareness of the effects of such changes on the performance of the sewer systems has steadily increased. For countries with high average temperatures and low per capita water consumption, such as Mozambique, these changes are particularly important due to the potential increase of sulphide formation and the consequent release of hydrogen sulphide and other malodorous or toxic gases to the atmosphere. A major expansion of the sewer systems in the main cities of Mozambique is expected in the near future, with the associated longer wastewater travel times and increasing problems of septicity and hydrogen sulfide gas impacts. In order to better understand the in-sewer processes under local conditions, evaluate risks and exemplify how to support general drainage systems planning, two different approaches for modeling the performance of a Maputo separate sewer system were applied, based on: AEROSEPT, an empirical formulation, and WATS, a conceptual and more complex approach.
A narrow bandgap SiGe channel superlattice bandgap engineered 1T DRAM cell for low voltage operation and extended hole retention time (2011)

We propose a SiGe channel superlattice bandgap engineered (SiGe SBE) 1-transistor dynamic random access memory (1T DRAM) cell structure for improved generation and extended retention of hot holes adopting a narrow bandgap Si0.8Ge0.2 channel even with an extremely short gate length of 30 nm. The proposed SiGe channel SBE 1T DRAM shows longer retention time than the Si channel SBE 1T DRAM. It also provides improved design flexibility by optimizing the structural and process parameters, so the retention characteristics get better. Especially, it should be noted that the retention time can be further improved if the doping concentration of the Si buffer layer decreases. The narrow bandgap SiGe channel SBE structure also allows the 1T DRAM cell to generate more electron–hole pairs during the write '1' operation through the impact ionization in the channel under a high electric field. In addition to the long retention time with the SBE structure, the narrow bandgap SiGe channel SBE 1T DRAM cell enables the 1T DRAM cell to have a fast write speed and to operate at lower voltage, thanks to the narrow bandgap Si0.8Ge0.2 channel.

Identifying mass transport deposits using image logs and core in Bone Spring and Wolfcamp Formations, Delaware Basin: Implications for mapping, facies distribution, reservoir properties, and unraveling subsurface chaos (2022)

This paper presents an integrated workflow and set of criteria, using core and image logs, to recognize deep-water mass transport deposits (MTDs) in the Bone Spring and Wolfcamp formations in the Delaware Basin. Packages of deformed bedding in deep-water environments may be associated with a variety of processes that post-date initial deposition, which include mass transport deposits, overbank collapse, de-watering, and loading. Recognition of MTDs (i.e., debris flows, slumps, slides) has implications for understanding reservoir architecture, reservoir characterization, top selection, mapping, and the drilling and completion of horizontal wells in unconventional targets deposited in a deep-water setting.
Effect of the dry‐cold season dormancy on the tonic and phasic neural control of heart rate in the toad, Bufo paracnemis (2000)

This work examined basal heart rate and autonomic cardiac tone as well as sympathetic cardiac reactivity to hypotension induced by systemic nitroprusside injection in dormant toads (dry-cold season), Bufo paracnemis, comparing the values with those of toads collected during the active months (hot-rainy season). Autonomic tone was calculated according to the method of Lin and Horwath ('72), which allows its evaluation as a percentage of intrinsic heart rate. Specimens were maintained in an outdoors terrarium except for the week preceding surgery, when they were transferred to indoor nonclimatized tanks. The heart rate of dormant toads (27.8 ± 2.7 beats/min) was lower than that of active toads at rest (38.6 ± 2.3). Cholinergic tone was higher than adrenergic tone both in active (26.2% and 7.8%, respectively) and aestivated (19.5% and 4.8%, respectively) animals. Thus, cholinergic tone and adrenergic tone were both lower in dormant animals. The reflex tachycardia elicited by nitroprusside-induced hypotension was lower in aestivated toads (9.3 ± 0.9 beats/min) when compared to active toads (19.9 ± 1.0), indicating a reduced sympathetic reactivity. Nitroprusside-induced hypotensions were not different in the two groups. We conclude that at rest Bufo paracnemis heart is under the influence of a double cholinergic and adrenergic tone, and that both influences, as well as the reflex adrenergic reactivity to the unloading produced by nitroprusside-induced hypotension, are reduced in aestivated toads.

Cavitation threshold determination —Can we do it? (2014)

As clinical applications, which harness acoustic cavitation, become more commonplace, it becomes more and more important to be able to determine the threshold pressures at which it is likely to occur. In our studies, we have used a suite of different detection techniques in an effort to determine these thresholds. These include passive cavitation detection, transducer impedance monitoring, and visual appearance. Different methods of acoustic signal processing have been compared. The resultant cavitation thresholds will be discussed.
IgG-Fc glycosylation before and after rituximab treatment in immune thrombocytopenia (2020)

The interactions of antibodies with myeloid Fcγ receptors and the complement system are regulated by an Asn297-linked glycan in the Fc portion of IgG. Alterations of serum IgG-Fc glycosylation have been reported in various autoimmune diseases, and correlate with treatment response and disease activity. We hypothesized that IgG-Fc glycosylation is altered in immune thrombocytopenia (ITP) and associates with response to anti-CD20 monoclonal antibody treatment (rituximab). IgG-Fc glycosylation was analyzed by liquid chromatography-mass spectrometry. We found that IgG-Fc glycosylation was identical between refractory ITP patients (HOVON64 trial; N = 108) and healthy controls (N = 120). Two months after rituximab treatment, we observed a shift in Fc glycosylation, with a mean 1.7% reduction in galactosylation for IgG1 and IgG4 and a mean 1.5% increase for bisection in IgG1, IgG2/3 and IgG4 (adjusted p < 1.7 × 10<sup>-3</sup> and p < 2 × 10<sup>-4</sup>, respectively). Neither baseline nor longitudinal changes in IgG-Fc glycosylation after rituximab were associated with clinical treatment response. We conclude that IgG-Fc glycosylation in refractory ITP is similar to healthy controls and does not predict treatment responses to rituximab. The observed changes two months after treatment suggest that rituximab may influence total serum IgG-Fc glycosylation. Overall, our study suggests that the pathophysiology of refractory ITP may differ from other autoimmune diseases.

Sol-gel Synthesis and Characterization of Zn[sub 2]SiO[sub 4]:Mn@SiO[sub 2] Spherical Core-Shell Particles (2005)

The synthesis and characterization of phosphor layers on spherical silica spheres, i.e., core-shell particles of are described in this paper. First, monodisperse silica spheres with an average size around have been obtained via the Stöber method by the hydrolysis and condensation of tetraethoxysilane under base condition (using as the catalyst). Second, the silica spheres are coated with phosphor layers by a sol-gel process. The resulting core-shell particles are characterized by X-ray diffraction, Fourier transform infrared spectroscopy, field emission scanning electron microscope, energy-dispersive X-ray spectroscopy, transmission electron microscopy, photoluminescence, low-voltage cathodoluminescence, as well as kinetic decay. The results confirm that the -annealed sample consists of crystalline shells and amorphous cores with spherical morphology and narrow size distribution. The particles show the green emission at corresponding to transition of under the excitation of UV , vacuum UV , and electron-beams . The luminescence intensity has been studied as a function of coating number, accelerating voltage, and filament current, respectively.
Mutation selection and the natural history of cancer (1975)

Survival of the rapidly renewing tissues of long-lived animals like man requires that they be protected against the natural selection of fitter variant cells (that is, the spontaneous appearance of cancer). This article discusses three possible protective mechanisms and shows how they could explain various features of the natural history of certain common cancers of man. Reproduced by permission. J.

In Romance with the Materials of Mobile Interaction : A Phenomenological Approach to the Design of Mobile Information Technology (2003)

This thesis deals analytically and through design with the issue of Human­Computer Interaction (HCI) with mobile devices; mobile interaction. Specifically, it is an investigation into and a capitalization on the multistable kinds of relations that arise between the threefold of human user, artifact, and world, and how dealing with this kind of technology and these relations in many ways must be regarded as different from mainstream HCI. This subject matter is theoretically, methodologically, and empirically approached from two to HCI unconventional outlooks: a phenomenological and a design-oriented attitude to research. The main idea pursued in this work is that while HCI for historical reasons follows a tradition of disembodiment, its opposite—embodiment—needs to come into view as an alternative design ideal when dealing with mobile interaction. The tradition of disembodiment in HCI, how it is applied within mobile interaction, and the conceptual switch in focusing on embodiment and human, technology, world relations are thoroughly analyzed and discussed. A proper understanding of these issues are seen as necessary for the primary purpose of this book: to provide designers of mobile interaction with the conceptual means needed to construct new and better styles of mobile interactions. To equip designers and researchers with the possibility of choosing an alternative path, the book provides a range of alternative conceptualizations for design, modeled primarily around phenomenological concepts such as embodiment, meaning, and involvement. In order to minimize the distance between these new notions and how they may be practically applied for design, four research prototypes are presented and discussed that all in different ways capitalize on these conceptualizations. The thesis concludes with an empirical-style study, which uses the Repertory Grid Technique to elicit the participants’ experiences of using a number of mobile information technology devices, including the research prototypes presented in this work.
CFD Investigation of the Effects of Different Diluents on the Emissions in a Swirl Stabilized Premixed Combustion System (2005)

Recently, new cycles for power generation, such as wet cycles and cycles for CO2 capture, have gained increasing interest. These new cycles use some sort of dilution in the air/fuel mixture, e.g. steam or CO2. Gas turbine cycles using LCV gases can also be said to fit this description. Almost all modern gas turbines use a lean premixed combustion system, since it combines low NOx emissions with high combustion efficiency. The main objective of this paper is to study the influence of different diluents on the NOx and CO emissions at different inlet temperature, equivalence ratio, pressure and mass flow. The studied combustor was a premixed swirl stabilized combustor with optical access and emission sampling equipment. The combustor uses Danish natural gas as its main fuel. Computational fluid dynamics (CFD) has been employed to perform the investigations. It is common knowledge that turbulence models based on the Buissinesq assumption are not generally capable of handling a highly swirling flow in a correct way. Therefore, a differential Reynolds stress model (DRSM) has been employed for modeling of the turbulence. The turbulent combustion has been modeled with the level-set flamelet library approach (FLA). In this approach a laminar flamelet is linked to turbulent flow field via a non-reacting scalar G and its variance. The laminar flamelet is modeled with separate code. This code solves the combustion development with a detailed reaction mechanism for a laminar, non-stretched and premixed one-dimensional flame. This is of great importance when emissions are to be predicted. All fluid dynamics computations were performed with the commercial CFD code Star-CD, version 3.20, where the FLA combustion model was implemented through Fortran based user subroutines. The computed flow field was validated against experimental data during non-reaction flow conditions. The computations showed good agreement with the experimental data. The computed CO and NOx emissions showed the same trends as the experimental data for the reacting case with an undiluted flame, when the equivalence ratio was altered. The computed emissions were used to build up an emission map for different dilutions during different operation conditions.
