Innovative direct synthesis of adipic acid by air oxidation of cyclohexane (2006)

A single-step air oxidation of cyclohexane, based on a new lipophilic catalytic system, leads to the production of adipic acid with excellent results. The catalytic activity outperforms previous reported catalytic systems for this reaction, and provides an environmentally benign alternative to an important industrial reaction.
Less-costly activated carbon for sewage treatment (1977)

Lignite-aided sewage treatment is based on absorption of dissolved pollutants by activated carbon. Settling sludge is removed and dried into cakes that are pyrolyzed with lignites to yield activated carbon. Lignite is less expensive than activated carbon previously used to supplement pyrolysis yield.
Modeling and Experiment of Leading Edge Separation Control Using SDBD Plasma Actuators (2007)

This work presents the study of the single-dielectric barrier discharge aerodynamic plasma actuator. To model the physics of the plasma discharge, a space-time lumpedelement circuit model was developed. The model solution compared well to some of the characteristic features of the discharge such as the dependence of the sweep velocity and maximum extent of the ionized air as functions of the applied voltage and a.c. driving frequency. The time-dependent charge distribution obtained from the model was used to provide boundary conditions to the electric field equation that was used to calculate the time dependent electric potential. The was then used to calculate the space-time distribution of the actuator body force. An application of the plasma actuators to the leading-edge separation control on the NACA 0021 airfoil was studied numerically and experimentally. The results were obtained for a range of angles of attack for uncontrolled flow, and steady and unsteady plasma actuators located at the leading edge of the airfoil. The control of the lift stall was of particular interest. Improvement in the airfoil characteristics were observed in the numerical simulations at post-stall angles of attack with the plasma actuators. The computational results corresponded very well with the experiments.
Mining the <i>Moraxella catarrhalis</i> Genome: Identification of Potential Vaccine Antigens Expressed during Human Infection (2008)

Moraxella catarrhalis is an important cause of respiratory infections in adults and otitis media in children. Developing an effective vaccine would reduce the morbidity, mortality, and costs associated with such infections. An unfinished genome sequence of a strain of M. catarrhalis available in the GenBank database was analyzed, and open reading frames predicted to encode potential vaccine candidates were identified. Three genes encoding proteins having molecular masses of approximately 22, 75, and 78 kDa (designated Msp [Moraxella surface proteins]) (msp22, msp75, and msp78, respectively) were determined to be conserved by competitive hybridization using a microarray, PCR, and sequencing of the genes in clinical isolates of M. catarrhalis. The genes were transcribed when M. catarrhalis was grown in vitro. These genes were amplified by PCR and cloned into Escherichia coli expression vectors. Recombinant proteins were generated and then studied using enzyme-linked immunosorbent assays with preacquisition and postclearance serum and sputum samples from 31 adults with chronic obstructive pulmonary disease (COPD) who acquired and cleared M. catarrhalis. New antibody responses to the three proteins were observed for a small proportion of the patients with COPD, indicating that these proteins were expressed during human infection. These studies indicate that the Msp22, Msp75, and Msp78 proteins, whose genes were discovered using genome mining, are highly conserved among strains, are expressed during human infection with M. catarrhalis, and represent potential vaccine antigens.

Mecamylamine in Tourette's Syndrome: A Two-Year Retrospective Case Study (2000)

Mecamylamine at 2.5-6.25 mgm/day has no significant peripheral parasympathetic activity and may be safely taken long term (up to 550 days in this study). It has a significant effect in relieving motor and vocal tics and in mood and behavior disturbances of children, adolescents, and adults with TS.
Litho-Aware Machine Learning for Hotspot Detection (2017)

In this paper, we propose a novel methodology for machine learning-based hotspot detection that uses lithography information to build support vector machine (SVM) during its learning process. Unlike previous studies that use only geometric information or require a post-optical proximity correction (OPC) mask, this proposed method utilizes detailed optical information but bypasses post-OPC mask by sampling latent image intensity and uses those points to train an SVM model. The results suggest high accuracy and low false alarm, and faster runtime compared with methods that require a post-OPC mask.
AMBRI biosensor: stabilizing artificial membranes and receptor attachment (1999)

The AMBRI Ion Channel Switch biosensor is a novel scanning technology with broad application in a variety of fields. The technology is based on an artificial bilayer membrane attached to gold through hydrophilic tethers. The lamellar bilayer membrane possesses electrical characteristics similar to black (bilayer) lipid membranes being sealed with a capacitance of approximately 0.6 (mu) F/cm<SUP>2</SUP>, is fluid, and is stable to a variety of media including plasma and whole blood and to challenges with solvent solutions. Receptors/antibodies can be attached to the membrane through biotin-streptavidin linkages, and use of caged biotin species allows optical patterning of the membrane surface.
DWDM optical millimeter-wave generation for radio-over-fiber using an optical phase modulator and an optical interleaver (2006)

We have proposed and experimentally demonstrated a novel scheme to generate a dense wavelength-division multiplexing (DWDM) optical millimeter-wave source by using an optical phase modulator and an optical interleaver. The stability of the DWDM optical millimeter wave generation is largely improved because we use an optical phase modulator without a dc-bias controller and an optical interleaver is subsequently employed to suppress the optical carrier of the DWDM source, which is not as temperature sensitive as a fiber Bragg grating. Moreover, the limitation of chromatic dispersion is greatly reduced due to avoiding the generation of higher order sidebands via driving the phase modulator with optimized RF signal

Large and thick single crystals can now be produced at very high growth rates, and the mechanical properties, chemistry, and optical and electronic properties of the material can be tuned over a wide range. The single crystals can have extremely high fracture toughness and exceptionally high hardness following high-pressure/high-temperature annealing. CVD single-crystal diamonds will make possible a new generation of high-pressure-temperature experimentation to study Earth and planetary materials and should enable a variety of other new scientific and technological applications.

Evaluation of the M37 human rotavirus vaccine in 2- to 6-month-old infants (1991)

Human rotavirus strain M37, isolated from an asymptomatic neonate, was evaluated as a live oral vaccine in a double-blinded, placebo-controlled trial involving 282 infants ages 2 to 6 months. Either 10(4) or 10(5) plaque-forming units (PFU) of the M37 vaccine were tested in 102 and 39 infants, respectively. The vaccine was well-tolerated; fever on Days 1 to 7 after vaccination was recorded in 12 and 18% of infants receiving 10(4) and 10(5) PFU of the M37 vaccine, respectively, compared with 6% of those receiving placebo; none of the vaccinees developed diarrhea. A rotavirus IgA enzyme-linked immunosorbent assay serum antibody response was detected in 47 and 76% of the infants receiving the 10(4) and 10(5) PFU vaccines, respectively. No clinical protection against rotavirus diarrhea was observed in the group vaccinated with the 10(4) PFU dose; the number of infants vaccinated with 10(5) PFU was too small for evaluation of vaccine efficacy. The M37 vaccine in a titer of 10(4) PFU was found to be inadequate; the 10(5) PFU dose was more immunogenic than the lower dose and warrants further study for clinical efficacy.
Nano- and Micro-Scale Oxidative Patterning of Titanium Implant Surfaces for Improved Surface Wettability (2015)

A simple and scalable surface modification treatment is demonstrated, in which nano- and microscale features are introduced into the surface of titanium (Ti) substrates by means of a novel and eco-friendly oxidative aqueous solution composed of hydrogen peroxide (H202) and sodium bicarbonate (NaHCO3). By immersing mirror-polished Ti discs in an aqueous mixture of 30 wt% H2O2/5 wt% NaHCO3 at 23 +/- 3 degrees C for 4 h, it was confirmed that this mixture is capable of generating microscale topographies on Ti surfaces. It also simultaneously formed nanochannels that were regularly arranged in a comb-like pattern on the Ti surface, thus forming a hierarchical surface structure. Further, these nano/micro-textured Ti surfaces showed great surface roughness and excellent wettability when compared with control Ti surfaces. This study demonstrates that a H2O2/NaHCO3 mixture can be effectively utilized to create reproducible nano/microscale topographies on Ti implant surfaces, thus providing an economical new oxidative solution that may be used effectively and safely as a Ti surface modification treatment.
Densely folded silicon photonic wire biosensors in ring resonator and Mach-Zehnder configurations (2008)

We demonstrate silicon photonic wire evanescent field sensors formed by folding long photonic wire waveguides into dense spiral paths that occupy spot sizes less than 150 mum in diameter, and are hence suitable for biochip array formats. These sensors are incorporated into both ring resonator and Mach-Zehnder interferometer (MZI) interrogation circuits, and tested by monitoring streptavidin protein adsorption. The level of detection is less than 1% of a monolayer in either configuration. Using a balanced MZI design, we show that the sensors can be insensitive to temperature and wavelength, while retaining a very high sensitivity to molecular adsorption.

Rateless feedback codes (2012)

This paper proposes a concept called rateless feedback coding. We redesign the existing LT and Raptor codes, by introducing new degree distributions for the case when a few feedback opportunities are available. We show that incorporating feedback to LT codes can significantly decrease both the coding overhead and the encoding/decoding complexity. Moreover, we show that, at the price of a slight increase in the coding overhead, linear complexity is achieved with Raptor feedback coding.

<title>InP Optoelectronic Mixers</title> (1981)

InP optoelectronic switches are shown to offer potential performance advantages over conventional diode bridges as electronic mixers. Devices with micrometer-geometry interdigitated-finger structures have been fabricated and tested. The geometry of such structures can be chosen to optimize mixer performance over a wide range of frequencies. Mixer operation has been demonstrated at 100 MHz and calculations indicate good performance into the GHz range with existing InP technology and GaAs diode laser sources.

Multiplexed and Electrically Modulated Plasmon Laser Circuit (2012)

With unprecedented ability to localize electromagnetic field in time and space, the nanometer scale laser promises exceptionally broad scientific and technological innovation. However, as the laser cavity becomes subwavelength, the diffraction of light prohibits the directional emission, so-called the directionality, one of the fundamental attributes of the laser. Here, we have demonstrated a deep subwavelength waveguide embedded (WEB) plasmon laser that directs more than 70% of its radiation into an embedded semiconductor nanobelt waveguide with dramatically enhanced radiation efficiency. The unique configuration of WEB plasmon laser naturally integrates photonic and electronic functionality allowing both efficient electrical modulation and wavelength multiplexing. We have demonstrated a plasmonic circuit integrating five independently modulated multicolored plasmon laser sources multiplexed onto a single semiconductor nanobelt waveguide, illustrating the potential of plasmon lasers for large scale, ultradense photonic integration.

Non-Constant Parameter NC Tool Path Generation on Sculptured Surfaces (1992)

Abstract An algorithm for three-axis NC tool path generation on sculptured surfaces is presented. Non-constant parameter tool contact curves are defined on the part by intersecting parallel planes with the part model surface Four essential elements of this algorithm are introduced: initial chordal approximation, true machining error calculation, direct gouge elimination, and non-constant parameter tool pass interval adjustment. A software implementation of this algorithm produces graphical output depicting the tool path superimposed over the part surface, and it outputs cutter location (CL) data for further postprocessing. Several applications examples are presented to demonstrate the capabilities of the algorithm The results of this technique are compared to those generated from a commercially available computer-aided manufacturing program, and indicate that equivalent accuracy is obtained with many fewer CL points.
Simple analytical models for the temperature dependent threshold behavior of depletion-mode devices (1979)

Threshold voltage shifts in ion-implanted depletion-mode MOSFETs depart substantially from the usual dose proportional shift of enhancement-mode devices. Analytic expressions for the relationship between threshold voltage shift and implanted donor dose and position are extended to include impurity freezeout at low temperatures, and a simple model for the observed low substrate sensitivity at low temperature is presented. Criteria to avoid parasitic subthreshold conduction in depletion-mode devices are also established using the threshold shift formulation.
High gain tunable antenna with fractal, swept-back radiator (2009)

In this paper our analysis starts from Chu's theoretical fundamental limits of small antenna. The main efforts include: elaborate design modified Fractal radiator and low loss RF tuning with software defined architecture. Test results show significant improvement in radiation efficiency, selectivity and broaden band. Such as, the gain of new Fractal tunable antenna is -7.5dBi at 30MHz against passive antenna -23dBi and monopole tunable -15dBi. This antenna is ideal for replacement of existing VHF/UHF antenna on high speed aircraft and support SINCGAR and HAVEQUICK frequency hopping.
Overproduction of <scp>l</scp> -Cysteine and <scp>l</scp> -Cystine by <i>Escherichia coli</i> Strains with a Genetically Altered Serine Acetyltransferase (1998)

Organisms that overproduced L-cysteine and L-cystine from glucose were constructed by using Escherichia coli K-12 strains. cysE genes coding for altered serine acetyltransferase, which was genetically desensitized to feedback inhibition by L-cysteine, were constructed by replacing the methionine residue at position 256 of the serine acetyltransferase protein with 19 other amino acid residues or the termination codon to truncate the carboxy terminus from amino acid residues 256 to 273 through site-directed mutagenesis by using PCR. A cysteine auxotroph, strain JM39, was transformed with plasmids having these altered cysE genes. The serine acetyltransferase activities of most of the transformants, which were selected based on restored cysteine requirements and ampicillin resistance, were less sensitive than the serine acetyltransferase activity of the wild type to feedback inhibition by L-cysteine. At the same time, these transformants produced approximately 200 mg of L-cysteine plus L-cystine per liter, whereas these amino acids were not detected in the recombinant strain carrying the wild-type serine acetytransferase gene. However, the production of L-cysteine and L-cystine by the transformants was very unstable, presumably due to a cysteine-degrading enzyme of the host, such as cysteine desulfhydrase. Therefore, mutants that did not utilize cysteine were derived from host strain JM39 by mutagenesis with N-methyl-N'-nitro-N-nitrosoguanidine. When a newly derived host was transformed with plasmids having the altered cysE genes, we found that the production of L-cysteine plus L-cystine was markedly increased compared to production in JM39.
The Aerocapacitor: An Electrochemical Double‐Layer Energy‐Storage Device (1993)

We have applied unique types of carbon foams developed at Lawrence Livermore National Laboratory to make an "Aerocapacitor." The aerocapacitor is a high power‐density, high energy‐density, electrochemical double‐layer capacitor which uses carbon aerogels as electrodes. These electrodes possess very high surface area per unit volume and are electrically continuous in both the carbon and electrolyte phase on a 10 nm scale. Aerogel surface areas range from 100 to 700 m2/cm3 (as measured by BET analysis), with bulk densities of 0.3–1.0 g/cm3. This morphology permits stored energy to be released rapidly, resulting in high power densities (7.5 kW/kg). Materials parameterization has been performed, and device capacitances of several tens of Farads per gram and per cm3 of aerogel have been achieved.
Effects of Encapsulation Microenvironment on Embryonic Stem Cell Differentiation (2008)

Pluripotent embryonic stem cells represent a promising renewable cell source to generate a variety of differentiated cell types. Although many investigators have described techniques to effectively differentiate stem cells into different mature cell lineages, their practicality is limited by the absence of large scale processing consideration and low yields of differentiated cells. Previously we have established a murine embryonic stem cell alginate-poly-l-lysine microencapsulation differentiation system. The three-dimensional alginate microenvironment maintains cell viability, is conducive to ES cell differentiation to hepatocyte lineage cells, and maintains differentiated cellular function. In the present work, we demonstrate that hepatocyte differentiation is mediated by cell-cell aggregation in the encapsulation microenvironment. Both cell aggregation and hepatocyte functions, such as urea and albumin secretion, as well as increased expression of cytokaratin 18 and cyp4507a, occur concomitantly with surface E-cadherin expression. Furthermore, by incorporating soluble inducers, such as retinoic acid, into the permeable microcapsule system, we demonstrate decreased cell aggregation and enhanced neuronal lineage differentiation with the expression of various neuronal specific markers, including neurofilament, A2B5, O1 and GFAP. Therefore, as a result of capsule parameter and microenvironment manipulation, we are capable of targeting cellular differentiation to both endodermal and ectodermal cell lineages.
