Coupled mesoscale—continuum simulations of copper electrodeposition in a trench (2004)

Abstract Copper electrodeposition in submicron trenches involves phenomena that span many orders of magnitude in time and length scales. In the present work, two codes that simulate electrochemical phenomena on different time and length scales were externally linked. A Monte Carlo code simulated surface phenomena in order to resolve surface roughness evolution and trench in‐fill. A 2‐D finite difference code simulated transport phenomena in the diffusion boundary layer outside the trench. The continuum code passed fluxes to the Monte Carlo code, which passed back a concentration to the continuum code. A numerical instability that arises in the multiscale linked code was suppressed by filtering the concentration data passed from the Monte Carlo code to the finite difference code. The resulting simulation results were self‐consistent for a sufficiently small amount of filtering. © 2004 American Institute of Chemical Engineers AIChE J, 50: 226–240, 2004
Ecological Intensification of Food Production by Integrating Forages (2021)

Forage crops have the potential to serve multiple functions, providing an ecological framework to sustainably intensify food production, i.e., ecological intensification. We review three categories of forages (annual forages, perennial forages, and dual-use perennial crops/forages) we believe hold the greatest promise for ecologically intensifying food production. Annual cover crops can provide additional forage resources while mitigating nutrient losses from agricultural fields when they are intercropped with, interseeded into, or following an annual crop, for instance. The integration of perennial forages either temporally, such as annual crop rotations that include a perennial forage phase, or spatially, such as the intercropping of perennial forages with an annual cash crop, provide weed suppression, soil quality, and yield and crop quality benefits. Dual-use crops/forages can provide forage and a grain crop in a single year while providing multiple ecological and economic benefits. However, tradeoffs in balancing multiple functions and limitations in reducing the risks associated with these practices exist. Advancing our understanding of these systems so we can overcome some of the limitations will play a critical role in increasing food production while promoting positive environmental outcomes.
Fast algorithm for radio propagation modeling in realistic 3-D urban environment (2015)

Abstract. Next generation wireless communication systems will consist of a large number of mobile or static terminals and should be able to fulfill multiple requirements depending on the current situation. Low latency and high packet success transmission rates should be mentioned in this context and can be summarized as ultra-reliable communications (URC). Especially for domains like mobile gaming, mobile video services but also for security relevant scenarios like traffic safety, traffic control systems and emergency management URC will be more and more required to guarantee a working communication between the terminals all the time.

Synthesis of mesoporous γ-AIOOH@Fe3O4 magnetic nanomicrospheres (2012)

Mesoporous γ-AlOOH@Fe3O4 magnetic nanomicrospheres were synthesized using superparamagnetic Fe3O4 nanoparticles as the core and aluminum isopropoxide(AIP) as the aluminum source.The obtained magnetic nanomicrospheres were characterized by X-ray powder diffraction(XRD),transmission electron microscopy(TEM),scanning electron microscopy(SEM),N2 adsorption-desorption and vibrating sample magnetometry(VSM).The effects of preparation parameters such as hydrolysis time of AIP,concentration of AIP and coating layer number on microspheres were investigated.The results indicated that the mesoporous γ-AlOOH@Fe3O4 magnetic nanomicrospheres consisted of a mesoporous-AlOOH shell and a Fe3O4 magnetic core.The diameter of γ-AlOOH@Fe3O4 nanomicrospheres was about 200 nm,the thickness of mesoporous-AlOOH shell was about 5 nm and the average pore size was 3.8 nm.The thickness of the mesoporous-AlOOH shell could be controlled via layer-by-layer coating times.The formation mechanism of the mesoporous-AlOOH shell involved a chemisorption-hydrolysis process.
Narrowband, polarization-independent free-space wave notch filter (2005)

A two-dimensional-corrugated-slab-waveguide add/drop filter providing 100% resonant reflection at 1.55 microm wavelength for both TE and TM polarizations with identical FWHM is designed. The fabricated device exhibits a reflectivity spectrum of more than 95% peak reflection for both polarizations at 1.537 microm. The coupling scheme involves the TE0 guided mode only; it is made relatively tolerant by means of a double-sided crossed grating.
Data for scaling-up hydrothermal waste water treatment process (2001)

Abstract Hydrothermal oxidation of wastes is developed as an alternative technique in order to limit the toxic end-product formation, the waste volume and the energy supply. We are now working on the transfer of this technology, and so on the determination of data for scaling-up the hydrothermal oxidation process. The main data concern the knowledge of reactive pathway, the determination of reaction kinetic and thermal parameter. Kinetic and thermal data have been determined for the hydrothermal oxidation of acetic acid as well as the reactive pathway of hydrothermal oxidation of a C, H, O, N compound, the fenuron (C6H5-NH-CO-N(CH3)2).
The use of the high-vacuum cathode-ray tube for recording high-speed transient phenomena (1938)

The paper describes a portable apparatus operated from the 50-cycle a.c. mains and devised for the visual examination and/or photographic recording of controlled or uncontrolled high-speed transient phenomena.A high-vacuum glass-bulb type of cathode-ray tube is employed, with external photography. The maximum working voltage is 5000 volts, and the beam is normally shut off by means of a negative voltage on the modulating grid. A 3-electrode spark-gap is incorporated and is so arranged that when broken down by an incoming transient, or artificiallyapplied impulse, it brings the cathode-ray spot to full brilliance almost instantaneously for a controllable length of time, and, at the same time, sweeps it across the screen at a speed which can be varied from 1 or 2 microseconds to 1 millisecond for a single horizontal sweep. A simple oscillatory circuit operated by the spark-gap is arranged to provide a time-marking wave when desired.
Multiple parameter estimation with quantized channel output (2010)

We present a general problem formulation for optimal parameter estimation based on quantized observations, with application to antenna array communication and processing (channel estimation, time-of-arrival (TOA) and direction-of-arrival (DOA) estimation). The work is of interest in the case when low resolution A/D-converters (ADCs) have to be used to enable higher sampling rate and to simplify the hardware. An Expectation-Maximization (EM) based algorithm is proposed for solving this problem in a general setting. Besides, we derive the Crame¿r-Rao Bound (CRB) and discuss the effects of quantization and the optimal choice of the ADC characteristic. Numerical and analytical analysis reveals that reliable estimation may still be possible even when the quantization is very coarse.
Continuous Flow Cell Separation From Human Peripheral Blood Using Dielectrophoresis and Numerical Analysis (2013)

Cell manipulation using dielectrophoresis (DEP) has a great potential for biological applications in diagnostic devices because it has a capability to separate specific cells from mixed heterogeneous solutions, e.g., whole blood, selectively based on intrinsic dielectrophoretic characteristics. Thus, it does not require additional chemical tagging, which can lead to undesirable cell responses (1). Previous DEP cell separation has been run in a discontinuous mode, which may result in more complicated procedures, so that developing continuous flow DEP separation devices in practical sizes for larger throughput clinical applications is an unmet need. In this research, we model numerically a continuous flow dielectrophoresis (CF-DEP) device that was developed with novel angled-electrode design in a MEMs platform, and a pulsing mode was introduced between neighboring electrodes to obtain efficient cell separation. This allows examination of characteristic features of the electrode design and the coupling effect of dielectric and hydraulic forces to particle movement.
Microscopic carbon distribution in Si1−yCyalloys: A Raman scattering study (1997)

Si${}_{1\ensuremath{-}y}$C${}_{y}$ alloys grown by solid-phase epitaxy of carbon-implanted Si were investigated with Raman spectroscopy. A comparison between the experimental Raman spectrum and the spectrum predicted from ab initio calculations shows that the carbon distribution in these samples is more randomized than in similar alloys grown by molecular-beam epitaxy. It is argued that epitaxial, layer-by-layer growth promotes the formation of ordered Si-C structures.
Elevated BIS and Entropy values after sugammadex or neostigmine: an electroencephalographic or electromyographic phenomenon? (2012)

Nano magnetite decorated multiwalled carbon nanotubes: a robust nanomaterial for enhanced carbon dioxide adsorption (2010)

It has long been seen as a demanding task to counteract the raised levels of greenhouse gases including carbon dioxide (CO2). Current worldwide research is focused on the investigation of materials which can capture large amounts of CO2 through physical or chemical adsorption. The present work focuses on a high pressure CO2 adsorption study of functionalized MWNTs (f-MWNTs) and a magnetite decorated MWNT nanocomposite. Multiwalled carbon nanotubes (MWNTs) were prepared by a catalytic chemical vapor deposition method followed by purification and functionalization. Magnetite (Fe3O4) nanoparticles were decorated over the f-MWNT surface by a chemical method. The functionalized MWNTs and magnetite decorated MWNTs were characterized by electron microscopy, X-ray powder diffraction, Raman spectroscopy and FTIR spectroscopy. The CO2 adsorption capacity was measured using high pressure Sieverts' apparatus. A large enhancement in the CO2 adsorption capacity was achieved by decorating magnetite nanoparticles over the MWNT surface.
Sintering of SiC by Low Temperature Plasma (1990)

SiC powder compacts were sintered in inductively coupled plasma (ICP) at 4MHz. Boron and carbon were added to SiC powder as sintering aids in the present experiments. The plasma used here was low temperature Ar plasma working at low gaseous pressure=0.2-6.5kPa, since it was easy for samples to be inserted into plasma. Parameters influencing the densification were gaseous pressure, gas flow rate, sintering duration and r.f. out-put power. SiC was found to be extensively densified under the experimental conditions: gaseous pressure=1.0kPa, gas flow rate=70-270 SCCM, r.f. power=12kW, duration=2min. The weight loss during sintering was a problem to be solved in the present low temperature plasma. Morphological studies showed that abnormal grain growth could not be observed. A crystallographic change was observed from 15R and 3C to 6H after plasma sintering.

Leading Impulse Response Identification via the Weighted Elastic Net Criterion (2016)

This paper deals with the problem of finding a low-complexity estimate of the impulse response of a linear time-invariant discrete-time dynamic system from noise-corrupted input-output data. To this purpose, we introduce an identification criterion formed by the average (over the input perturbations) of a standard prediction error cost, plus a weighted l1 regularization term which promotes sparse solutions. While it is well known that such criteria do provide solutions with many zeros, a critical issue in our identification context is where these zeros are located, since sensible low-order models should be zero in the tail of the impulse response. The flavor of the key results in this paper is that, under quite standard assumptions (such as i.i.d. input and noise sequences and system stability), the estimate of the impulse response resulting from the proposed criterion is indeed identically zero from a certain time index (named the leading order) onwards, with arbitrarily high probability, for a sufficiently large data cardinality. Numerical experiments are reported that support the theoretical results, and comparisons are made with some other state-of-the-art methodologies.
Valuation of dynamic reactive power support based on MW transaction implementation considerations (2004)

This paper presents a reactive power valuation method with regarding to its effect on realization of MW transactions. The security constraint optimization model in which the objective function is maximization of transactions is solved by the genetic algorithm approach. The proposed scheme allocates a specific amount of MW transactions to each dynamic reactive power source. An index is introduced to drive VAr value from the calculated optimal parameters of power network. This index represents the system-wide effect of MVAr sources on MW transactions implementations. Application of proposed method has been illustrated using IEEE 30 and 14 bus test system. Results are discussed and compared in different conditions of the system.

New Institutional Approaches to Formal Organizations (2012)

This chapter addresses anthropology's place within new institutional theory and some of the ways in which it may contribute to understanding of formal organizations. The chapter begins by exploring the meaning of the institutional construct and its relationship to formal organizations, and illustrates some potential advantages to an anthropological approach to new institutionalism. Certain large-scale formal organizations can be understood as exhibiting institutional characteristics in their own right, and therefore are subject to processes of institutional stability and change (including potentially deinstitutionalization) over long periods of time. Finally, the chapter explores three distinctive analytic dimensions of an anthropological approach to new institutionalism which may orient contributions to this field with those of other disciplines and provide a framework for future discussion.

SPICE modeling of memristive, memcapacitative and meminductive systems (2009)

A methodology of SPICE modeling of general memristive, memcapacitative, and meminductive systems is proposed and their special cases such as memristors (MR), memcapacitors (MC), and meminductors (ML) are given. These elements are included alongside the conventional R, C, and L elements in a proposed constellation, which generalizes the hitherto approach when the memristor is regarded as a fourth missing passive element. It is shown that the memristor, designed in HP laboratories, can be modeled as a first-order memristive system with nonlinear dependence of the time derivative of the state variable on this variable and on the current flowing through. The outputs of SPICE analyses are consistent with the hitherto published results.
Hypoxia Preconditioned Mesenchymal Stem Cells Improve Vascular and Skeletal Muscle Fiber Regeneration After Ischemia Through a Wnt4-dependent Pathway (2010)

Mesenchymal stem cells (MSC) are multipotent postnatal stem cells, involved in the treatment of ischemic vascular diseases. We investigate the ability of MSC, exposed to short-term hypoxic conditions, to participate in vascular and tissue regeneration in an in vivo model of hindlimb ischemia. Transplantation of hypoxic preconditioned murine MSC (HypMSC) enhanced skeletal muscle regeneration at day 7, improved blood flow and vascular formation compared to injected nonpreconditioned MSC (NormMSC). These observed effects were correlated with an increase in HypMSC engraftment and a putative role in necrotic skeletal muscle fiber clearance. Moreover, HypMSC transplantation resulted in a large increase in Wnt4 (wingless-related MMTV integration site 4) expression and we demonstrate its functional significance on MSC proliferation and migration, endothelial cell (EC) migration, as well as myoblast differentiation. Furthermore, suppression of Wnt4 expression in HypMSC, abrogated the hypoxia-induced vascular regenerative properties of these cells in the mouse hindlimb ischemia model. Our data suggest that hypoxic preconditioning plays a critical role in the functional capabilities of MSC, shifting MSC location in situ to enhance ischemic tissue recovery, facilitating vascular cell mobilization, and skeletal muscle fiber regeneration via a paracrine Wnt-dependent mechanism.
Comparative Study of Advanced Oxidation Processes to Treat Petroleum Wastewater (2015)

Abstract This study was carried out to compare the performance of different oxidation processes, such as solar photo-Fenton reaction, solar photocatalysis by TiO 2 , and the combination of the two for the treatment of petroleum wastewater from Sohar Oil Refinery by a central composite design with response surface methodology. The degradation efficiency was evaluated in terms of chemical oxygen demand (COD) and total organic carbon (TOC) reductions. Solar photocatalysis by the TiO 2 /Fenton method improved the performance of the photocatalyst at neutral pH for petroleum wastewater without the need to adjust the pH during this treatment. Under acidic conditions, the solar photo-Fenton process is more efficient than solar TiO 2 photocatalysis while it is less efficient under alkaline conditions. The TiO 2 dosage and pH are the two main factors that improved the TOC and COD reductions in the solar photocatalysis using combined TiO 2 /Fenton and the solar TiO 2 photocatalysis processes while the pH and H 2 O 2 concentration are the two key factors that affect the solar photo-Fenton process.

Glutathione reductase activity in serum and liver tissue of human and rat with hepatic damage. (1975)

Glutathione reductase activity of both serum and liver tissue homogenates was measured in normal controls and in cases of hepatic parenchymatous diseases, and the results were compared with those from animal experiments in which hepatic damage was produced by CCl4 injection. Glutathione reductase showed a different attitude from those of transaminases and alkaline phosphatases under these clinical and experimental conditions. Glutathione reductase activity increased in both serum and liver in patients with hepatic damage, and this increase occurred earlier than the changes in alkaline phosphatase activity.
Diskrete Signale und ihr Spektrum (1997)

In den Kapiteln 1 bis 10 haben wir mächtige Werkzeuge für den Umgang mit kontinuierlichen Signalen und Systemen kennengelernt. Den Übergang von in der Natur vorkommenden kontinuierlichen Signalen zu abgetasteten Signalen, die für eine digitale Verarbeitung nötig sind, haben wir in Kapitel 11 vollzogen. Der Definitionsbereich der abgetasteten Signale war immer noch eine kontinuierliche (Zeit)-Variable, so daß wir die bekannten Werkzeuge, u.a. die Fourier-Transformation, verwenden konnten.
Crude Drugs from Aquatic Plants. III. Quantitative Analysis of Triterpene Constituents in Alismatis Rhizoma by Means of High Performance Liquid Chromatography on the Chemical Change of the Constituents during Alismatis Rhizoma Processing (1994)

As a series of study on the evaluation of Alismatis Rhizoma and the chemical characterization of the processing, a quantitative method by high performance liquid chromatography (HPLC) for ten triterpene constituents, alisols A, A monoacetate, B, B monoacetate, E 23-acetate, F, and G and 13,17-epoxyalisol A, 11-deoxyalisols B and B 23-acetate, has been developed. By the use of this HPLC method, the contents of these triterpenes in various Alismatis Rhizoma and the fresh rhizoma of Alisma oriental JUZEPC, originated from in China, Taiwan, and Japan were examined. Furthermore, the chemical change of the triterpene constituents during the drying process of the rhizoma of Alisma oriental has been investigated and it was found that the bioactive triterpenes of Alismatis Rhizoma such as alisol A and alisol A monoacetate were artificially formed during the drying process.
