Protein engineering of cytochrome P450cam (CYP101) for the oxidation of polycyclic aromatic hydrocarbons (2000)

Mutations of the active site residues F87 and Y96 greatly enhanced the activity of cytochrome P450(cam) (CYP101) from Pseudomonas putida for the oxidation of the polycyclic aromatic hydrocarbons phenanthrene, fluoranthene, pyrene and benzo[a]pyrene. Wild-type P450(cam) had low (<0.01 min(-1)) activity with these substrates. Phenanthrene was oxidized to 1-, 2-, 3- and 4-phenanthrol, while fluoranthene gave mainly 3-fluoranthol. Pyrene was oxidized to 1-pyrenol and then to 1,6- and 1,8-pyrenequinone, with small amounts of 2-pyrenol also formed with the Y96A mutant. Benzo[a]pyrene gave 3-hydroxybenzo[a]pyrene as the major product. The NADH oxidation rate of the mutants with phenanthrene was as high as 374 min(-1), which was 31% of the camphor oxidation rate by wild-type P450(cam), and with fluoranthene the fastest rate was 144 min(-1). The oxidation of phenanthrene and fluoranthene were highly uncoupled, with highest couplings of 1.3 and 3.1%, respectively. The highest coupling efficiency for pyrene oxidation was a reasonable 23%, but the NADH turnover rate was slow. The product distributions varied significantly between mutants, suggesting that substrate binding orientations can be manipulated by protein engineering, and that genetic variants of P450(cam) may be useful for studying the oxidation of polycyclic aromatic hydrocarbons by P450 enzymes.
Toward efficient large-scale performance modeling of integrated circuits via multi-mode/multi-corner sparse regression (2010)

In this paper, we propose a novel multi-mode/multi-corner sparse regression (MSR) algorithm to build large-scale performance models of integrated circuits at multiple working modes and environmental corners. Our goal is to efficiently extract multiple performance models to cover different modes/corners with a small number of simulation samples. To this end, an efficient Bayesian inference with shared prior distribution (i.e., model template) is developed to explore the strong performance correlation among different modes/corners in order to achieve high modeling accuracy with low computational cost. Several industrial circuit examples demonstrate that the proposed MSR achieves up to 185× speedup over least-squares regression [14] and 6.7× speedup over least-angle regression [7] without surrendering any accuracy.
Facile Synthesis of Na<sub>0.33</sub>V<sub>2</sub>O<sub>5</sub> Nanosheet-Graphene Hybrids as Ultrahigh Performance Cathode Materials for Lithium Ion Batteries (2015)

Na0.33V2O5 nanosheet-graphene hybrids were successfully fabricated for the first time via a two-step route involving a novel hydrothermal method and a freeze-drying technique. Uniform Na0.33V2O5 nanosheets with a thickness of about 30 nm are well-dispersed between graphene layers. The special sandwich-like nanostructures endow the hybrids with high discharge capacity, good cycling stability, and superior rate performance as cathodes for lithium storage. Desirable discharge capacities of 313, 232, 159, and 108 mA·h·g(-1) can be delivered at 0.3, 3, 6, and 9 A·g(-1), respectively. Moreover, the Na0.33V2O5-graphene hybrids can maintain a high discharge capacity of 199 mA·h·g(-1) after 400 cycles even at an extremely high current density of 4.5 A·g(-1), with an average fading rate of 0.03% per cycle.

Natural image denoising: Optimality and inherent bounds (2011)

The goal of natural image denoising is to estimate a clean version of a given noisy image, utilizing prior knowledge on the statistics of natural images. The problem has been studied intensively with considerable progress made in recent years. However, it seems that image denoising algorithms are starting to converge and recent algorithms improve over previous ones by only fractional dB values. It is thus important to understand how much more can we still improve natural image denoising algorithms and what are the inherent limits imposed by the actual statistics of the data. The challenge in evaluating such limits is that constructing proper models of natural image statistics is a long standing and yet unsolved problem. To overcome the absence of accurate image priors, this paper takes a non parametric approach and represents the distribution of natural images using a huge set of 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">10</sup> patches. We then derive a simple statistical measure which provides a lower bound on the optimal Bayesian minimum mean square error (MMSE). This imposes a limit on the best possible results of denoising algorithms which utilize a fixed support around a denoised pixel and a generic natural image prior. Our findings suggest that for small windows, state of the art denoising algorithms are approaching optimality and cannot be further improved beyond ~ 0.1dB values.
Diamond-Graphite Equilibrium Line from Growth and Graphitization of Diamond (1961)

Diamond growth occurs at high temperatures and pressures in the presence of certain molten metals which serve as solvent catalysts. The zones of pressure and temperature in which diamond growth occurs have been determined for a number of metals. These zones are bounded on the low-temperature side by the melting point of the metal-carbon eutectic at pressure. They are bounded on the high-temperature side by the diamond-graphite equilibrium line. This experimentally determined equilibrium line agrees very closely with the theoretical extrapolation of the thermodynamically calculated line proposed by Berman and Simon, viz., P(kbar)=7.1+0.027T(∘K).
Demand Matching Wind Power Generation With Wide-Area Measurement and Demand-Side Management (2007)

This paper outlines the benefits of combining wide-area monitoring and control systems with demand-side management applications for more effective network utilization. Besides a general overview of these two powerful technologies in combination, a technical architecture, and economic benefit in the context of power system operation is encouraged. A case, where a wind park's feed into a neighboring system and wind power generation's non-deterministic behavior caused expensive spot market energy purchase, demonstrates the impact of the proposed wide-area measurement system with ripple control for demand-side management. This example underlines application areas for some typical network configurations with decentralized power generation or dedicated corridors to neighbored systems. It further shows the potential of the proposed load-control scheme with respect to economic, ecological, and reliable power system operation against the background of increasingly decentralized and renewable generation units
Trajectory planning of a manipulator of a space robot using a neural network (2002)

In space, the movement of the space robot is subjected to the law of angular momentum conservation as a nonholonomic constraint. Hence, different trajectories of a manipulator result in different final states in inertial space. To ensure safe and reliable operations of a space robot, it is necessary to plan the trajectory of the manipulator mounted on a space robot before the operations. In this paper, the trajectory planning method using a neural network for the manipulator of a space robot is proposed. The trajectory obtained by this method is compared with that obtained by analytical method for the approximate model in which the mass of the manipulator is neglected. The method is applied to the exact model in which the mass of the manipulator can not be neglected.
Properties of highly purified leukotriene C4 synthase of guinea pig lung. (1988)

Leukotriene C4 (LTC4) synthase, which conjugates LTA4 and LTA4-methyl ester (LTA4-me) with glutathione (GSH) to form LTC4 and LTC4-me, respectively, has been solubilized from the microsomes of guinea pig lung and purified 91-fold in four steps to a specific activity of 692 nmol/10 min per mg protein using LTA4-me as substrate. LTC4 synthase of guinea pig lung was separated from microsomal GSH S-transferase by Sepharose CL-4B chromatography and further purified by DEAE-Sephacel chromatography, agarose-butylamine chromatography, and DEAE-3SW fast-protein liquid chromatography. It was also differentiated from the microsomal GSH S-transferase, which utilized 1-chloro-2,4-dinitrobenzene as a substrate, by its heat lability and relative resistance to inhibition by S-hexyl-GSH. The Km value of guinea pig lung LTC4 synthase for LTA4 was 3 microM and the Vmax was 108 nmol/3 min per microgram; the Km values for LTA3 and LTA5 were similar, and the Vmax values were about one-half those obtained with LTA4. The conversion of LTA4-me to LTC4-me was competitively inhibited by LTA3, LTA4, and LTA5, with respective Ki values of 1.5, 3.3, and 2.8 microM, suggesting that these substrates were recognized by a common active site. IC50 values for the inhibition of the conjugation of 20 microM LTA4-me with 5 mM GSH were 2.1 microM and 0.3 microM for LTC4 and LTC3, respectively. In contrast, LTD4 was substantially less inhibitory (IC50 greater than 40 microM), and LTE4 and LTB4 had no effect on the enzyme, indicating that the mixed type product inhibition observed was specific for sulfidopeptide leukotrienes bearing the GSH moiety.
Epitaxial silicon n<sup>+</sup>-p-&amp;#960;-p<sup>+</sup>avalanche photodiodes for optical fiber communications at 800 to 900 nanometers (1976)

Silicon n <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> -p-π-p <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">+</sup> avalanche photodiodes, having high speed (1 ns response time), low noise and high current gain, have been developed for optical fiber communications. These detectors provide a 16 dB improvement in sensitivity over nonavalanching photodiodes in optical receivers operating at 825 nm and 44.7 Mbit/sec. To facilitate fabrication on large diameter wafers, achieve uniform avalanche gain, and obtain quantum efficiencies greater than 90% at 800 to 850 nm, the avalanche photodiodes are constructed from 50 µm thick, high resistivity epitaxial silicon. At an average gain of 100, their resulting excess noise factor is only 4 to 6 times the shot noise limit. Low dark currents and good reliability are achieved through the use of guard rings, channel stops, bulk and surface gettering, dielectric passivation and surface field plates.

PV faults: Overview, modeling, prevention and detection techniques (2013)

Recent PV faults and subsequent fire-hazards on April 5, 2009, in Bakersfield, California, and April 16, 2011, in Mount Holly, North Carolina provide evidence of a lack of knowledge among PV system manufacturers and installers about different PV faults. The conducted survey within the scope of this paper describes various faults in a PV plant, and explains the limitations of existing detection and suppression techniques. Different fault detection techniques proposed in literatures have been discussed and it was concluded that there is no universal fault detection technique that can detect and classify all faults in a PV system. Moreover, this digest proposes a transmission line model for PV panels that can be useful for interpreting faults in PV using different refelectomery methods.
"Thin" vs. "fat" visualization clients (1998)

A client, by definition, have minimal software requirements necessary to function as a user interface front-end for a Web enabled application and raises the issue of client vs. server data visualization rendering. Real-time visual data manipulation doesn't translate well into a thin client. While the VRML file format allows distribution of visualization scenes to the Web, the user has no access to the actual underlying data source. The mapping of numerical data into geometry format (VRML) takes place at the server side.Local data manipulation, information drill-down technique, context sensitive menus, object picking and other interactive user interface functions that traditionally have been available on the client are now controlled by the visualization server. In the thin client model, nearly all functionality is delivered from the server side of the visualization engine while the client perform very simple display and querying functions.Web components and Plug-ins are now being used to overcome some of these limitations. Java allows the creation of applets and JavaBeans and we have Windows/COM components. These components together with data reduction methods can significantly increase the data interaction between the client application and user, and allow tasks to be executed on the client. Highly interactive user interface tasks are delivered that provide point-and-click navigation through multidimensional data structures. Visual data interfaces such as information drilling, moving a cutting plane through a volume data set etc can be supported.The implication of using a static VRML environment with reduced geometry is compared to sending compressed data to the client and perform interactive client data visualization on a desktop.

Chaotic Motion in Unsteady Vortical Flows (1993)

Application of nonlinear dynamical systems theory to hydrodynamics started with the work by Henon (1966) on ABC flows (short for) Arnold, Beltrami & Childress, see an extensive study by Dombre et al. (1986 on this subject, who numerically studied the fluid particle motion in the ABC flow and showed that the flow contains the KAM tori and chaotic motion of the Smale horseshoe type. On a separate line, the investigation on chaotic motion of some vortical flows induced by point vortices initiated by the work of (1975, 1978, 1979), who exhibited global stochastic properties (ergodicity and mixing) of a four-vortex system, and continued by further work of (1979, 1980, 1983, 1985, 1989), who showed chaotic motion for two-dimensional vortical flows by numerically computing Poincare sections. In the case of three vortices, it is shown that the three-vortex problem is itself integrable but the induced vortical flow (motion of fluid particles) is in general a non-integrable problem. Application of homoclinic orbit theory to chaotic mixing and transport in some particular vortical flows, on the other hand, was first done by (1983), and later expounded in detail in the case for a vortex pair byRom-Kedar, Leonard and Wiggins (1990). For a systematic review on this aspect, one is referred to (1983) for background materials on nearly integrable Hamiltonian systems; (1989) for an overview and examples; (1992) where mathematical tools for chaotic transport (tangle dynamics) are summarized; and the monograph by (1991) where pattern formations are emphasized.KeywordsUnstable ManifoldChaotic MotionFluid ParticlePoint VortexIntegrable Hamiltonian SystemThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
Use of Real-Time PCR with Multiple Targets To Identify <i>Pseudomonas aeruginosa</i> and Other Nonfermenting Gram-Negative Bacilli from Patients with Cystic Fibrosis (2003)

Pseudomonas aeruginosa and other gram-negative isolates from patients with cystic fibrosis (CF) may be difficult to identify because of their marked phenotypic diversity. We examined 200 gram-negative clinical isolates from CF respiratory tract specimens and compared identification by biochemical testing and real-time PCR with multiple different target sequences using a standardized combination of biochemical testing and molecular identification, including 16S rRNA partial sequencing and gyrB PCR and sequencing as a "gold standard." Of 50 isolates easily identified phenotypically as P. aeruginosa, all were positive with PCR primers for gyrB or oprI, 98% were positive with exotoxin A primers, and 90% were positive with algD primers. Of 50 P. aeruginosa isolates that could be identified by basic biochemical testing, 100% were positive by real-time PCR with gyrB or oprI primers, 96% were positive with exotoxin A primers, and 92% were positive with algD primers. For isolates requiring more-extensive biochemical evaluation, 13 isolates were identified as P. aeruginosa; all 13 were positive with gyrB primers, 12 of 13 were positive with oprI primers, 11 of 13 were positive with exotoxin A primers, and 10 of 13 were positive with algD primers. A single false-positive P. aeruginosa result was seen with oprI primers. The best-performing commercial biochemical testing was in exact agreement with molecular identification only 60% of the time for this most difficult group. Real-time PCR had costs similar to those of commercial biochemical testing but a much shorter turnaround time. Given the diversity of these CF isolates, real-time PCR with a combination of two target sequences appears to be the optimum choice for identification of atypical P. aeruginosa and for non-P. aeruginosa gram-negative isolates.
THE SCALING OF BIRD IMPACT LOADS (1979)

This report describes an experimental study which was conducted to investigate the loads produced by the impact of 1800 g and 3600 g birds. Both real birds and bird simulants were tested. Impact pressures were measured and compared with smaller bird impact results obtained on previous testing programs. The magnitude of the impact pressures was found to be independent of bird size. The temporal and spatial distribution of impact pressures scaled linearly with bird dimensions. The impact behavior of large birds was consistent with flow models developed to describe small bird impacts. It was concluded that large and small birds display the same fundamental impact loading processes and that these processes are adequately described by the previously developed flow model.
Electroenzymatic Polypyrrole-intercalator Sensor for the Determination of West Nile Virus cDNA (2006)

The chemical binding of a redox acridone derivative onto a polypyrrole film functionalized by N-hydroxysuccinimide groups provided an electrode capable of anchoring DNA duplex by simple insertion of the grafted acridone intercalator into the dsDNA solution. This electrode was applied for the detection of a ssDNA derived from a West Nile virus sequence. The latter was thus amperometrically detected after its hybridization in solution with a biotinylated complementary oligonucleotide followed by its anchoring and labeling by a glucose oxidase at 1 pg/mL.
Novel High-speed Linear GaN Technology with High Efficiency (2019)

We report the first demonstration of graded-channel GaN HEMTs operating in the millimeter-wave frequency range. At 30 GHz, these graded-channel GaN HEMTs demonstrated excellent PAE of 65% at an associated power density of 3 W/mm. The measured PAE and output power density show great improvement over other mm-wave T-gated AlGaN/GaN HEMT devices. Under two-tone linearity characterization at 30 GHz, PAE of about 50% was demonstrated with C/IM3 of 30 dBc, which is very promising for mm-wave linear and efficient amplifiers without digital pre-distortion.
Large-Area Printing of Optical Gratings and 3D Photonic Crystals Using Solution-Processable Nanoparticle/Polymer Composites (2014)

We demonstrate a readily scalable print, lift, and stack approach for producing large-area, 3D photonic crystal (PC) structures and optical gratings. UV-assisted nanoimprint lithography was used to pattern grating structures composed of highly filled nanoparticle (NP) polymer composite resists with tunable refractive indices (RI). The gratings were robust and upon release from a support substrate were oriented and stacked to yield 3D PCs. The composite resists were composed of anatase titania (TiO2) NPs, between 5 and 30 nm in diameter, and a UV-curable optical resist (Norland Optical Adhesive 60). The RI of the composite resists was tuned between 1.58 and 1.92 at 800 nm while maintaining excellent optical transparency. The grating structure dimensions, line width, depth, and pitch were easily varied by simply changing the imprint mold. A six-layer log-pile stack was prepared using a composite resist containing 50 wt % TiO2 NPs with an RI of 1.72 and yielded up to 72% reflection at 840 nm and a minimum reflection of 50% over broad angles of incidence (25–65°) and grating areas of >6 cm2. The grating patterning process is readily scalable for roll-to-roll production, and the ability to tailor RI as well as grating structure dimensions and orientation offers an attractive means for large-area production of tuned optical materials, while automating alignment will enable high-volume production of PCs.
