Remediation of Soils and Ground Water Contaminated by Aromatic and Chlorinated Hydrocarbons and Metals (2004)

Many of the Indiana Department of Transportation (INDOT) sites are contaminated with aromatic hydrocarbons and chlorinated solvents; these contaminants often occur in the form of light non-aqueous phase liquids (LNAPLs) or dense non-aqueous phase liquids (DNAPLs). Considerable effort has recently been focused on developing in-situ technologies for removing or destroying NAPL source zones, and several potentially viable methods have emerged, including in-situ chemical oxidation (ISCO). ISCO has become an attractive remediation option to managers at many contaminated sites. The three oxidants that are most often applied in-situ are hydrogen peroxide (H2O2) with iron catalysts, potassium permanganate (KMnO4), and ozone (O3). While each oxidant system has been field demonstrated to be effective in some instances, a clear understanding of these processes is important to the successful implementation of the technology. The primary goal of the laboratory experiments is to evaluate strategies for improving the effectiveness and efficiency of the oxidants as applied to aggressive remediation of source zones containing residual saturations of NAPLs, particularly as applied at INDOT sites. Several novel approaches have been taken to reach the goals of the study. The first approach enhances the application of Fenton's reagent in soil slurry systems, resulting in a better understanding of the magnitude of non-specific oxidant losses relative to consumption by the target compounds. The second approach explores minimizing non-specific losses of the oxidant by introducing the oxidant (KMnO4) in an encapsulated form. Finally, solubility enhancers are examined to enhance the aqueous NAPL concentrations. Significant enhancements in NAPL aqueous concentration will result in corresponding enhancements of the observed oxidation rate. Based on input from INDOT staff, selected sites will be assessed for amenability to remediation via in-situ oxidation. Efforts will be made to choose sites that are representative of a broad range of INDOT needs. Assessment required travel by senior personnel to specific sites to evaluate the nature and extent of contamination. Site visits were also be made by research assistants to collect soil samples for laboratory experiments.

Predicting Personality on Social Media with Semi-supervised Learning (2014)

Personality research on social media is a hot topic recently due to the rapid development of social media as well as the central importance of personality study in psychology, but most studies are conducted on inadequate label samples. Our research aims to explore the usage of unlabeled samples to improve the prediction accuracy. By conducting n user study with 1792 users, we adopt local linear semi-supervised regression algorithm to predict the personality traits of Micro blog users. Given a set of Micro blog users' public information (e.g., Number of followers) and a few labeled users, the task is to predict personality of other unlabeled users. The local linear semi-supervised regression algorithm has been employed to establish prediction model in this paper, and the experimental results demonstrate the usage of unlabeled data can improve the accuracy of prediction.
Modeling process latitude in UV projection lithography (1991)

The degree to which critical performance parameters are stable against small variations in process parameters is called process latitude. Advanced computer models of UV microlithography are used to study the impact of the notching phenomenon (exposure enhancement near steps in the exposure plane) on process latitude. It is shown that notching effects give rise to a rapid degradation of resist development process latitude.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Type I interferons as vaccine adjuvants against infectious diseases and cancer (2008)

Presently, new attention is given to type I interferons (IFNs) as essential factors linking innate and adaptive immunity. Several studies provided evidence about the importance of IFN-alpha in the differentiation of the Th1 subset, in the generation and activity of cytotoxic T lymphocytes, in the enhancement of a primary antibody response and in the activation of dendritic cells. Owing to their immunomodulatory properties, type I IFNs can represent good candidates to be used as adjuvants for vaccination. In the present review, we summarize recent studies in humans and in animal models, suggesting a possible application of type I IFNs as adjuvants for the development of more effective vaccines against infectious diseases and cancer.
Dependence of thermal stability of the titanium silicide/silicon structure on impurities (1990)

The effect of impurity on the thermal stability of titanium silicide (TiSi2)/single-crystal silicon (Si) structures has been studied. It is found that nitrogen and oxygen in the TiSi2 film significantly influence the morphological changes of a TiSi2/Si structure during high-temperature annealing at 1100 °C for 2–20 s. Nitrogen impurity improves the thermal stability of the TiSi2/Si structure, whereas oxygen degrades it.
Transmission Clutch Pressure Control System: Modeling, Controller Development and Implementation (2000)

<div class="htmlview paragraph">This paper describes the modeling, controller development, and implementation of a transmission clutch pressure control system. A nonlinear analytical model for the clutch pressure control system is developed and implemented using Matlab/Simulink, and validated by experimental data. The dominant dynamics are identified via model analysis, and a linear model is derived for controller design. Openloop (feedforward) and closed loop (feedback) pressure control strategies are designed and implemented in a test setup. Experimental results show that the combined feedforward and feedback control gives superior performance as compared to feedforward control alone.</div>
Selective Adsorption of Neutral Nitrogen Compounds from Fuel Using Ion-Exchange Resins (2010)

Adsorptive removal of hydrodesulfurization inhibitors, that is, nitrogen-containing compounds (N-compounds), was studied using model fuel which contains carbazole and dibenzothiophene in an n-dodecane−toluene mixture over ion-exchange resins (IXRs) in batch and in fixed-bed adsorption systems. The adsorptive capacity and selectivity for neutral N-compounds were examined. The high affinity for neutral N-compounds present in hydrocarbon feed was explained by hydrogen bonding between the chloride anion (with nonbonding electrons) and the neutral N-compounds. However, the presence of a flat charged cation, that is, N-alkylated pyridinium, is essential to ensure the adsorption of neutral N-compounds. The regeneration of the sorbent could be easily performed using polar organic solvent like methanol. Commercially available IXR bearing pyridinium chloride functionality (HPQ) was further evaluated with straight-run fuel oil. The N/S selectivity decreases, but analysis of the adsorbed compounds by gas chromatography/mass spectroscopy (GC/MS) shows that no paraffin and no monoaromatics were adsorbed. The results obtained provided new insight into the fundamental understanding of the adsorption mechanism of neutral N-compounds from hydrocarbon feed.
<scp>C</scp>9orf72 ablation in mice does not cause motor neuron degeneration or motor deficits (2015)

Our data suggest that C9orf72 loss-of-function, by itself, is insufficient to cause motor neuron disease. These results may have important implications for the development of therapeutic strategies for C9orf72-associated ALS.
Spontaneous ordering of nanostructures on crystal surfaces (1999)

A review is given of theoretical concepts and experimental results on spontaneous formation of periodically ordered nanometer-scale structures on crystal surfaces. Thermodynamic theory is reviewed for various classes of spontaneously ordered nanostructures, namely, for periodically faceted surfaces, for periodic surface structures of planar domains, and for ordered arrays of three-dimensional coherently strained islands. All these structures are described as equilibrium structures of elastic domains. Despite the fact that driving forces of the instability of a homogeneous phase are different in each case, the common driving force for the long-range ordering of the inhomogeneous phase is the elastic interaction. The theory of the formation of multisheet structures of islands is reviewed, which is governed by both equilibrium ordering and kinetic-controlled ordering. For the islands of the first sheet, an equilibrium structure is formed, and for the next sheets, the structure of the surface islands meets the equilibrium under the constraint of the fixed structures of the buried islands. The experimental situation for the fabrication technology of ordered arrays of semiconductor quantum dots is analyzed, including a discussion of both single-sheet and multiple-sheet ordered arrays.
The properties of co-sputtered YBa2Cu3O7 and CeO2 thin films (1996)

We have investigated the morphology and superconducting properties of off-axis co-sputtered thin films of YBa2Cu3O7 and CeO2. The composite films were made with CeO2 concentrations up to approximately 43%. Morphology investigations using x-ray diffraction and scanning electron microscopy suggest that films with less than 29% CeO2 may consist of a distorted YBCO crystal structure with Ce being incorporated into the lattice. Films with more than 29% consist of a new material phase. Tc and resistance ratio decreased with increasing CeO2 concentration. Degradation of Tc after photoresist processing was observed for films with higher amounts of CeO2. However, this degradation was reversed and Tc improved beyond that of the as-deposited film by processing the films with an oxygen plasma etch. The temperature dependence of the critical current near Tc showed two power law dependence regions with a crossover near 0.99 Tc for films having low concentrations of CeO2. This crossover shifted to lower temperatures for films with higher amounts of CeO2. Ic’s were decreased by small applied magnetic fields, and for some samples response was observed which was greater than 0.5 mA/G and increased with decreasing temperature. For a sample having 26% CeO2, a 40% reduction in critical current for a 2 G applied field was observed. These magnetic field responses indicate that this material may be a promising candidate for the development of Josephson vortex flow devices.
EXPRESS-1: a dynamically reconfigurable platform using embedded processor FPGA (2005)

This work presents a dynamically reconfigurable platform called EXPRESS-1, which uses the commercially available embedded processor FPGA. The system makes the most of a fully reconfigurable logic part to explore the area of fine-grained reconfigurable computing. A dynamic reconfiguration mechanism is implemented utilizing a real-time operating system, so device reconfiguration in response to application demand works without suspending other services. EXPRESS-1 features a transparent execution mechanism. Whether a function is executed by the hardware or software, the mechanism frees users from awareness of its execution manner. Furthermore, there is no need to explicitly specify reconfiguration commands into a program because the system determines if reconfiguration is needed based on current conditions. The development of EXPRESS-1 and the runtime reconfiguration mechanism of the fully reconfigurable logic are described. System capabilities are also reported through fundamental evaluations with some practical applications such as JavaVM, encryption processing, and image processing.
System Design for Wearable Blood Oxygen Saturation and Pulse Measurement Device (2015)

With the rapid development of information technology, the demands of sport monitoring research are rapidly increasing. Sport Internet of Things (IoTs) based on the sensor technique and modern communication technology are becoming more and more important to current sport training and daily activities. Sensor-based sport monitoring approaches lead people to take advantage of the wearable sport devices to monitor their own physiological parameters, in which we will focus on the blood oxygen saturation and the pulse measurement. In order to measure these two parameters, we will adopt near-infrared portable tissue oximeter with detection module using STM32 microprocessor. Near infrared spectroscopy (NIRS) is becoming a widely used research instrument to measure tissue oxygen (O2) status non-invasively. Continuous-wave spectrometers are the most commonly used devices, which provide semi-quantitative changes in oxygenated and deoxygenated hemoglobin in small blood vessels (arterioles, capillaries and venules). Through the measurement using the near-infrared technology, we could obtain the blood oxygen saturation and the pulse parameters. After obtaining the above two parameters, the portable device will send the data to the remote coaches or doctors via GPRS/WiFi/Zigbee networks. The data of the blood oxygen saturation and the pulse that is detected by the detection module are processed by the expert decision-making system in order to provide the coaches and doctors with the athlete condition. In addition, the data can be sent to the smart phones of the players, coaches or doctors through GPRS/WiFi networks, in which the blood oxygen saturation and the pulse data of the athletes can be displayed according to the requirement of the remote users. The test results show that the accuracy of measurement is high and the system is stable.
Control and performance of a single-phase dual active half bridge converter based on 15kV SiC IGBT and 1200V SiC MOSFET (2014)

A single-phase Dual Active Half Bridge (DAHB) DC-DC converter topology is evaluated for medium voltage (MV) application. A 15kV SiC-IGBT based three-level half-bridge is connected to the high voltage (HV) primary side of a high frequency (HF) transformer operating at 10kHz link-frequency. A 1200V SiC-MOSFET based two-level H-bridge is connected on the low voltage (LV) secondary side. This topology requires fewer switches and is suitable for MV application particularly with high step-down ratio where HF transformer may have considerable parasitics. It offers advantage of half blocking voltage requirement per device on the HV side and a simpler transformer saturation protection implementation. This paper also presents a robust D-Q based inner current control technique for the single phase DAB. The converters on both HV and LV side of the DAHB, can also be switched in 60° zero quasi-square mode to eliminate 3 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">rd</sup> harmonic voltage. The square and 60° modes of operation are compared. The DAHB converter topology and controls are validated with simulation results followed by experimental results.
A Managerial Guide to Forecasting (1986)

In order to predict the future we must examine the past in order to observe trends over periods of time and establish the degree of probability with which these trends are likely to repeat themselves in the future. All forecasts are wrong, and management must be aware of this fact and decide upon the degree of inexactitude that can be tolerated when planning for the future.

Cyclic pyridyltriazole–Cu(ii) dimers as supramolecular hosts (2013)

Tetradentate bis(pyridyltriazole) ligands containing aromatic spacers of different sizes react with Cu(2+) to produce metallo-supramolecular hosts that bind 1,4-diazabicyclo[2.2.2]octane molecules internally.
Effect of Helium Plasma on Low-k damage during Dry Resist Strip (2007)

Effect of He plasma dechuck step in a dry resist strip process is analyzed. It is demonstrated that UV radiation from He plasma during the dechuck step dissociates the adsorbed water molecules, which are formed during the preceding oxygen-plasma-based strip. A product of the water photolysis - oxygen radicals are detected as a source of light emission at 777 nm. The intensity the emission of electronically excited O* radicals correlates with degree of damage occurred during strip.
Three Different Binding Sites of Cks1 Are Required for p27-Ubiquitin Ligation (2002)

Previous studies have shown that the cyclin-dependent kinase (Cdk) inhibitor p27(Kip1) is targeted for degradation by an SCF(Skp2) ubiquitin ligase complex and that this process requires Cks1, a member of the highly conserved Suc1/Cks family of cell cycle regulatory proteins. All proteins of this family have Cdk-binding and anion-binding sites, but only mammalian Cks1 binds to Skp2 and promotes the association of Skp2 with p27 phosphorylated on Thr-187. The molecular mechanisms by which Cks1 promotes the interaction of the Skp2 ubiquitin ligase subunit to p27 remained obscure. Here we show that the Skp2-binding site of Cks1 is located on a region including the alpha2- and alpha1-helices and their immediate vicinity, well separated from the other two binding sites. All three binding sites of Cks1 are required for p27-ubiquitin ligation and for the association of Skp2 with Cdk-bound, Thr-187-phosphorylated p27. Cks1 and Skp2 mutually promote the binding of each other to a peptide similar to the 19 C-terminal amino acids of p27 containing phosphorylated Thr-187. This latter process requires the Skp2- and anion-binding sites of Cks1, but not its Cdk-binding site. It is proposed that the Skp2-Cks1 complex binds initially to the C-terminal region of phosphorylated p27 in a process promoted by the anion-binding site of Cks1. The interaction of Skp2 with the substrate is further strengthened by the association of the Cdk-binding site of Cks1 with Cdk2/cyclin E, to which phosphorylated p27 is bound.
Toughening fragile matter: mechanical properties of particle solids assembled from polymer-grafted hybrid particles synthesized by ATRP (2012)

The effect of polymer-graft modification on the structure formation and mechanical characteristics of inorganic (silica) nanoparticle solids is evaluated as a function of the degree of polymerization of surface-grafted chains. A transition from ‘hard-sphere-like’ to ‘polymer-like’ mechanical characteristics of particle solids is observed for increasing degree of polymerization of grafted chains. The elastic modulus of particle solids increases by about 200% and levels off at intermediate molecular weights of surface-grafted chains, a trend that is rationalized as a consequence of the elastic modulus being determined by dispersion interactions between the polymeric grafts. A pronounced increase (of about one order of magnitude) of the fracture toughness of particle solids is observed as the degree of polymerization of grafted chains exceeds a threshold value that is similar for both polystyrene and poly(methyl methacrylate) grafts. The increased resistance to fracture is interpreted as a consequence of the existence of entanglements between surface-grafted chains that give rise to energy dissipation during fracture through microscopic plastic deformation and craze formation. Within the experimental uncertainty the transition to polymer-like deformation characteristics is captured by a mean field scaling model that interprets the structure of the polymer shell of polymer-grafted particles as effective ‘two-phase’ systems consisting of a stretched inner region and a relaxed outer region. The model is applied to predict the minimum degree of polymerization needed to induce polymer-like mechanical characteristics and thus to establish ‘design criteria’ for the synthesis of polymer-modified particles that are capable of forming mechanically robust and formable particle solid structures.
Linear Fiber Impairments Mitigation of 40-Gbit/s Polarization-Multiplexed QPSK by Digital Processing in a Coherent Receiver (2008)

To provide higher capacity networks, 40-Gb/s transmission systems are under active development and their cost is on the way to be competitive with the one of 410 Gb/s. However, their lower tolerance to linear and nonlinear fiber impairments remains a major drawback for field deployment. To address the issue of linear impairments, coherent detection of multilevel formats with polarization division multiplexing appears as a promising solution by reducing the symbol rate to 10 Gbaud. Indeed, such coherent based systems have already demonstrated an improved tolerance to optical noise and an interesting capability to compensate for large amount of chromatic dispersion. In this paper, the tolerances to narrow optical filtering, chromatic dispersion, and polarization mode dispersion are investigated with coherent detection of 10-Gbaud quadrature phase shift keying (QPSK) with and without polarization division multiplexing. Moreover, the efficient mitigation of these linear impairments by digital processing in a coherent receiver is demonstrated in an ultralong haul transmission (4080 km) of 40-Gb/s QPSK polarization multiplexed data.
<title>Critical evaluation of test patterns for EO system performance characterization</title> (2001)

The traditional test pattern for end-to-end EO system performance testing in the laboratory has been the static 3- or 4-bar target. This choice was governed by linear systems approach. The introduction of under-sampled imagers such as IRFPAs (infrared focal plane array cameras) has challenged the testing community to develop an alternative test, because the occurrence of aliasing has a completely different effect on periodic targets (such as the bar target) and real, non-periodic targets. A new test should at least have the following properties: lab testing is objective and easy, the measure is representative for field performance, and modeling (sensor and human) the test should be relatively easy. Several alternative test methods and test patterns have already been proposed. An example is the TOD method that uses non-periodic test patterns. Other examples are the dynamic MRT that uses a moving 4-bar target, and the MTDP that uses the traditional static target but allows that not all four bars have to be present in the image. The development of real-time scene projection allows testing with real infrared targets under controlled conditions. The authors will discuss a large number of test patterns and methods and show their advantages and disadvantages for end-to-end EO system performance testing. They conclude that simple non-periodic spatial test patterns, such as used in the TOD, are the best choice for sensor performance characterization.
