Revenue and harmonics: an evaluation of some proposed rate structures (1995)

IEEE Recommended Practice 519 sets specific limits on harmonic voltages and currents at the "point of common coupling", which is usually interpreted as the revenue meter. Although most electric utilities will employ these limits simply to persuade and encourage their customers to reduce harmonics (and vice versa), it is also possible to construct economic incentives to encourage both the utility and the consumer to remain within the limits described in IEEE 519. This paper discusses seven approaches to this challenge, and discusses the advantages disadvantages of each. It appears that "harmonic-adjusted power factor" approach is practical, justifiable, compatible with existing rate structures, and relatively easy to implement.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Hematopoietic Development of Human Embryonic Stem Cells in Culture (2008)

The successful isolation and characterization of human embryonic stem cells (hESCs) provides a powerful tool to study the cellular and genetic mechanisms that mediate cell-fate decisions toward distinct developmental lineages. hESC-derived cells may also be suitable for novel cellular therapies. Significant progress in hematopoietic development of hESCs has demonstrated production of many types of blood cells from hESCs including myeloid, erythroid and lymphoid lineage cells, and possibly hematopoietic stem cells. Current established approaches to generate specific hematopoietic lineages are based on the initial pre-differentiation of hESCs into a heterogeneous mixture of cell populations. In this chapter, we describe two methods that have been successfully used in our laboratory: (1) co-culture with stromal cells derived from hematopoietic microenvironments and (2) x embryoid body (EB) formation. Subsequent to this early differentiation step, distinct progenitor cell populations can be derived, sorted, and utilized for further lineage-specific developmental studies.
Electrochemiluminescence from Tunicate, Tunichrome-Metal Complexes and Other Biological Samples (1996)

Low level intrinsic electrochemiluminescence (ECL) was induced from body fluids and homogenized tissues of oysters and several species of tunicates. No significant ECL was detected in human blood cell lysates, or bovine haematin, but minor ECL was observed in avian blood cell lysates. Both terrestrial grass and seagrass exhibited ECL, which is probably attributable to chlorophyll, since dead (brown) grass did not demonstrate ECL. It was postulated that organic-metal complexes in marine invertebrates were, at least in part, responsible for the intrinsic ECL, since such animals are known to be rich in organically bound metals. However, alternative biochemical mechanisms for the observed ECL, which do not involve metal chelates, are possible. Various metal ions were added to the invertebrate preparations to determine whether exogenous metals could enhance or inhibit the ECL reactions. Strongly oxidizing metal ions such as Ag+, Au+, Cu2+, Hg2+ and Sb2+ at > or = 100 ppm severely inhibited the intrinsic ECL response. No statistically significant ECL enhancement due to addition of metal ions was noted. ECL "profiles' were generated which demonstrated differences in the ECL responses of individual tunicate preparations to the presence of various exogenous metal ions. Differences in ECL profiles may represent differences in types or levels of endogenous metal chelates or other biochemical constituents. In addition, synthetic tunichromes (tunicate pigments) were analysed for ECL in the presence and absence of various added metal ions. One synthetic tunichrome isomer demonstrated a specific ECL interaction with Hg2+, while the other demonstrated broader ECL activity with several metal ions.
Identification, Characterization, and Recombinant Expression of Epidermicin NI01, a Novel Unmodified Bacteriocin Produced by Staphylococcus epidermidis That Displays Potent Activity against Staphylococci (2011)

We describe the discovery, purification, characterization, and expression of an antimicrobial peptide, epidermicin NI01, which is an unmodified bacteriocin produced by Staphylococcus epidermidis strain 224. It is a highly cationic, hydrophobic, plasmid-encoded peptide that exhibits potent antimicrobial activity toward a wide range of pathogenic Gram-positive bacteria including methicillin-resistant Staphylococcus aureus (MRSA), enterococci, and biofilm-forming S. epidermidis strains. Purification of the peptide was achieved using a combination of hydrophobic interaction, cation exchange, and high-performance liquid chromatography (HPLC). Matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) analysis yielded a molecular mass of 6,074 Da, and partial sequence data of the peptide were elucidated using a combination of tandem mass spectrometry (MS/MS) and de novo sequencing. The draft genome sequence of the producing strain was obtained using 454 pyrosequencing technology, thus enabling the identification of the structural gene using the de novo peptide sequence data previously obtained. Epidermicin NI01 contains 51 residues with four tryptophan and nine lysine residues, and the sequence showed approximately 50% identity to peptides lacticin Z, lacticin Q, and aureocin A53, all of which belong to a new family of unmodified type II-like bacteriocins. The peptide is active in the nanomolar range against S. epidermidis, MRSA isolates, and vancomycin-resistant enterococci. Other unique features displayed by epidermicin include a high degree of protease stability and the ability to retain antimicrobial activity over a pH range of 2 to 10, and exposure to the peptide does not result in development of resistance in susceptible isolates. In this study we also show the structural gene alone can be cloned into Escherichia coli strain BL21(DE3), and expression yields active peptide.
Si solar microcells for modules with reduced purity requirements, high voltage outputs and mechanically stretchable designs (2009)

We recently reported a strategy, in which modules consist of large-scale arrays of small, interconnected ultrathin (i.e. 1-20 ¿m) Si microcells (¿-cells) formed by anisotropic etching of bulk wafers and integrated with a soft printing technique. Here we report three new advances in this type of printed, ¿-cell technology. First, we show that ¿-cells formed with low purity, solar grade wafers (Dow Corning <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">®</sup> 101 SOG Si metal), can achieve efficiencies much higher than those possible with corresponding bulk cells formed with the same material. Second, we demonstrate high voltage mini-modules that incorporate these ¿-cells and lead to high voltage outputs. Finally, we demonstrate the fabrication of mechanically stretchable solar cell modules which are non-coplanar (i.e. arch shaped). The results show that these materials and designs yield a stretchable layout that can undergo strains of up to 30% without failure.
Radiative recombination dominated n-type monocrystalline CdTe/MgCdTe double-heterostructures (2016)

Monocrystalline CdTe/MgCdTe double-heterostructures (DHs) grown on lattice-matched InSb substrate have achieved remarkable carrier-lifetimes up to 3.6 μs recently. In this work, external luminescence quantum efficiency (η <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">ext</sub> ) of n-type CdTe/MgCdTe DHs is determined using Photoluminescence Quantum Efficiency (PLQE) measurements.

Rapid Detection of B Virus (Herpesvirus Simiae) DNA by Polymerase Chain Reaction (1993)

Rapid diagnosis of B virus (herpesvirus simiae) infection in humans followed by early antiviral treatment is essential for the patient's survival. To improve laboratory diagnosis of B virus infections, a polymerase chain reaction (PCR)-based test using synthetic oligonucleotide primers and probe was developed to detect B virus DNA in clinical samples. After the specificity of the PCR was assessed for detection of several B virus isolates, the method was used to investigate human and monkey specimens, and results were compared with those obtained by viral culture. PCR appeared to be more sensitive than conventional virus isolation and thus of practical use for a rapid identification of B virus infection when conventional viral cultures are negative.
Theoretical underpinnings for the efficiency of restorable networks using preconfigured cycles ("p-cycles") (2000)

Previous work on restorable networks has shown experimentally that one can support 100% restoration with an optimized set of closed cycles of spare capacity while requiring little or no increase in spare capacity relative to a span-restorable mesh network. This is important and unexpected because it implies that future restoration schemes could be as capacity efficient as a mesh network, while being as fast as ring-based networks because there is no real-time work at any nodes other than the two failure nodes. This paper complements the prior work by giving a greater theoretical basis and insight to support the prior results. We are able to show in a bounding-type of argument that the proposed protection cycles ("p-cycles") have as high a restoration efficiency as it is possible to expect for any type of preconfigured pattern, and are categorically superior to preconfigured linear segments or trees. We are also able to show that the capacity efficiency of a fully preconfigured p-cycle network has the same well-known lower bound as that of a span restorable mesh network which is cross-connected on-demand. These results provide a theoretical underpinning for the efficiency of p-cycles and confirmation of the experimental observations.
Novel and Selective 5-HT<sub>2C/2B</sub> Receptor Antagonists as Potential Anxiolytic Agents:  Synthesis, Quantitative Structure−Activity Relationships, and Molecular Modeling of Substituted 1-(3-Pyridylcarbamoyl)indolines (1998)

The synthesis, biological activity, and molecular modeling of a novel series of substituted 1-(3-pyridylcarbamoyl)indolines are reported. These compounds are isosteres of the previously published indole urea 1 (SB-206553) and illustrate the use of aromatic disubstitution as a replacement for fused five-membered rings in the context of 5-HT2C/2B receptor antagonists. By targeting a region of space previously identified as sterically allowed at the 5-HT2C receptor but disallowed at the 5-HT2A receptor, we have identified a number of compounds which are the most potent and selective 5-HT2C/2B receptor antagonists yet reported. 46 (SB-221284) was selected on the basis of its overall biological profile for further evaluation as a novel, potential nonsedating anxiolytic agent. A CoMFA analysis of these compounds produced a model with good predictive value and in addition good qualitative agreement with both our 5-HT2C receptor model and our proposed binding mode for this class of ligands within that model.
Transgenic potato tubers accumulate high levels of 1‐kestose and nystose: functional identification of a sucrose sucrose 1‐fructosyltransferase of artichoke (<i>Cynara scolymus</i>) blossom discs (1997)

By screening a cDNA library of artichoke (Cynara scolymus) blossom discs for fructosyltransferases, we isolated a clone designated Cy21. The deduced amino acid sequence shows homology to acid beta-fructosyl hydrolases and to the sucrose-fructan 6-fructosyltransferase (6-SFT) of barley. Transiently expressed in Nicotiana tabacum protoplasts, the Cy21 gene-product synthesized 1-kestose, indicating that Cy21 codes for a sucrose sucrose 1-fructosyltransferase (1-SST). The enzyme worked at physiologically relevant sucrose concentrations (25 mM sucrose). In the protoplast system, 1-kestose seemed to be the only fructan product of the 1-SST. The enzyme activity was not affected by pyridoxal-HCl, an inhibitor of both the beta-fructosyl hydrolase and the fructosyltransferase activity of invertases. The fructosyltransferase activity of the Cy21 gene-product, however, could be inhibited by Zn2+, Ag+ and Cu2+ ions. In artichoke plants the Cy21 transcript was highly abundant in primary roots and blossom discs. Transgenic potato tubers expressing Cy21 contain high levels of 1-kestose along with nystose and traces of fructosyl-nystose, supporting the conclusion that the Cy21 clone encodes a sucrose sucrose 1-fructosyltransferase.
Real-time traffic control for sustainable urban living (2014)

Traffic congestion significantly degrades the quality of life in urban environments. It results in lost time, wasted fuel resources and reduced air quality for urban residents. Recent work in real-time, schedule-driven control of traffic signal networks has introduced new possibilities for reducing congestion in urban environments. However so far, this work has focused mainly on achieving more efficient vehicle flows and on reducing emissions, and the broader mobility of other modes of traffic that are central to sustainable urban living - especially pedestrians - has not been emphasized in an integrated way. In this paper, we extend this decentralized, schedule-driven approach to traffic network control in the direction of this broader mobility objective. We focus specifically on accommodating pedestrians and optimizing the delay tradeoffs between vehicles and pedestrians. Three basic extensions are introduced and evaluated on a real-world road network. Simulation results are first presented which analyze the ability of the extended approach to achieve good delay tradeoffs under different pedestrian traffic conditions. Tests are then performed in the field at selected intersections of the target road network, to demonstrate the effectiveness of the approach in operation.
Thrombin-Antithrombin III and Plasm in-Antiplasmin Complexes as Indicators of in Vivo Activation of the Coagulation and/or Fibrinolytic Systems (1977)

Both the thrombin-antithrombin III and plasmin-antiplasmin complexes contain neoantigenic structures, not present in the parent molecules, to which non cross-reacting precipitating antibodies can be produced (Thromb.Res. 5, 577, 1974). This phenomenon has been used to develop immunochemical methods for the quantitation of these complexes in human blood (Thromb. Res 7, 235, 1975). Patients with in vivo activation of the coagulation and/or fibrinolytic systems consistently showed increased levels of enzyme-inhibitor complexes (Eur.J.Clin.Invest, in press, 1977). The circulatory half-life of these complexes was estimated to be several hours (0.5 to 0.75 days). On several occasions, increased plasmin-antiplasmin titers were observed in the presence of a normal screening hemostasis analysis, suggesting that these assays may be more sensitive indicators of in vivo activation of the coagulation-fibrinolytic systems that assays for fibrinogen degradation products. Studies to determine the clinical value of the measurement of these enzyme-inhibitor complexes as indicators of a prethrombotic state are in progress and will be reported.
Implementation of orthogonal frequency coded SAW devices using apodized reflectors (2006)

Recently, orthogonal frequency coding (OFC) has been presented as a novel method for coding SAW tags and sensors (Malocha et al.,2004). Orthogonal frequency coding is a spread spectrum technique and has been shown to provide enhanced processing gain and reduced time ambiguity resulting in greater range and increased sensitivity when compared with single carrier frequency devices. The sensor works both as a tag and a sensor with the ability to send back "tagged" sensor information in a multi-sensor environment. The tag information is provided by a series of reflectors which map into a known chip sequence. The time-chip- sequence is coded by differing OFC and PN sequences. Therefore, the implementation of an OFC sensor requires reflectors having differing local carrier frequencies. In the case of narrow fractional bandwidths or high reflectivity (such as on LiNbO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> ), it is desirable to adjust the reflectivity per electrode in the various chips. For varying system requirements, the use of weighted reflectors is an option; both apodization and variable weighted reflectors are investigated. Experimental results on cosine weighted apodized reflectors will be compared to COM predictions on YZ LiNbO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> . This paper presents several OFC SAW device embodiments that are employed using wideband input transducers and multiple weighted reflector gratings. The devices operate in the differential mode using gratings on either side of the transducer. The advantages of using the weighted reflector gratings in OFC SAW devices are discussed. OFC temperature sensor device experimental results are presented using weighted reflectors to obtain the proper time coded response and compared to predictions
The spin-wave nanoscale reconfigurable mesh and the labeling problem (2007)

In this article, we present a nanoscale reconfigurable mesh which is interconnected by ferromagnetic spin-wave buses. In this architecture, unlike the traditional spin-based nano structures which transmit charge, waves are transmitted. As a result, the power consumption of the proposed modules can be low. This reconfigurable mesh, while requiring the same number of switches and buses as the standard reconfigurable mesh, is capable of simultaneously transmitting N waves on each of the spin-wave buses. Because of this highly parallel feature, very fast and fault-tolerant algorithms can be designed. To illustrate the superior performance of the proposed spin-wave reconfigurable mesh, we present three fast labeling algorithms.
Resin-Capture and Release Strategy toward Combinatorial Libraries of 2,6,9-Substituted Purines (2002)

A resin-capture and release strategy for making combinatorial 2,6,9-trisubstituted purine libraries is demonstrated by capturing N9-derivatized purines at the C6 position with a thio-modified polymer. The C2 fluoro group is subsequently substituted with primary and secondary amines followed by thioether oxidation and release by C6 substitution with amines and anilines. This approach complements a previously reported strategy where a 6-phenylsulfenylpurine scaffold was captured at the C2 position with a resin-bound amine.(3)

Development of a horseback riding simulator (1991)

The riding simulator that we have developed consists of a horse-like body, swing mechanisms, a control unit, and an imaging device, and realizes the three basic riding motions of real horses-namely, walk, trot, and canter. In addition, a rider can experience the feeling of real horse riding by controlling the movement of the horse, such as start, stop, and change of the riding pace, and with the aid of an image of the horse's riding course displayed on a screen in front of the rider.
Primary Structure of a Member of the Serpin Superfamily of Proteinase Inhibitors from an Insect, Manduca sexta (1989)

A cDNA clone isolated from a fat body cDNA library from an insect, Manduca sexta, has been sequenced and shown to code for a member of the serpin family of proteinase inhibitors. The cDNA has an open reading frame which codes for a 392-residue polypeptide of Mr = 43,500 with a hydrophobic NH2-terminal sequence which appears to be a signal peptide. An alignment of this amino acid sequence with 11 members of the serpin superfamily reveals that the insect protein is 25-30% identical with most members of the superfamily. The alignment was used to construct an evolutionary tree of the serpin sequences analyzed, which indicates that the progenitor of the M. sexta serpin and the human serpins most closely related to it diverged from other serpin genes prior to the divergence of the vertebrates and invertebrates. The M. sexta serpin is predicted to inhibit elastase due to the presence of alanine at the P1 position of its reactive center and is classified as an alaserpin. A glycoprotein of Mr = 47,000 isolated from hemolymph of M. sexta larvae has an NH2-terminal sequence identical to that deduced from the alaserpin cDNA clone and inhibits porcine pancreatic elastase and bovine chymotrypsin.
