A Setup for the Coupling of a Thin-Layer Electrochemical Flow Cell to Electrospray Mass Spectrometry (2004)

A novel setup for the coupling of a commercially available thin-layer cell to electrospray mass spectrometry (ESI-MS) which allows the electrochemical reactions at the counter electrode to be straightforwardly separated from the flow into the mass spectrometer has been developed. In this way, interferences from reaction products formed at the counter electrode can be minimized. This reduces the risk of changes in the mass spectra as a result of electrochemical reactions in the solution. The described setup also enables the working electrode to be positioned close to the electrospray (ESI) emitter without the need for a grounding point or a long transfer line between the electrochemical cell and the electrospray emitter. By decoupling the electrochemical reactions in the flow cell and those in the electrospray emitter, improved facilities for studies of electrochemical reactions are obtained through a better control of the potential of the working electrode. The setup has been used to study the oxidation of a drug (Olsalazine), which previously has been found to involve chemical follow-up reactions. It is also demonstrated that uncharged thiols can be detected in ESI-MS after spontaneous adsorption on a gold working electrode, followed by oxidative desorption to yield sulfinates or sulfonates. This adsorption and potential-controlled desorption has been used for the preconcentration of micromolar concentrations of 1-hexanethiol as well as for desalting of solutions containing micromolar concentrations of thiols. The results indicate that the present on-line coupling of an electrochemical cell to ESI-MS provides promising possibilities for sample preconcentration, matrix exchange (including desalting), and ionization of neutral compounds, such as thiols.
Two Plasmodium knowlesi-specific antigens on the surface of schizont-infected Rhesus monkey erythrocytes induce antibody production in immune hosts. (1979)

Purified schizonts (6--10 nuclei) and membranes of schizont-infected erythrocytes from the Malaysian and Philippine strain of Plasmodium knowlesi are analyzed immunochemically using immunoglobulin of rhesus monkey hyperimmune sera against schizonts and of sera from naturally immune monkeys. The anti-schizont Ig identifies less than 20 immune components in Triton X-100-solubilized schizonts and membranes of infected cells. Of these antigens, 9 (component 1, 3, 4, 5, 6, 10, 11, 18, and 20) are common to parasites and membranes of infected erythrocytes, and 12 (2A,B, 6, 8, 9, 12, 13p, 14, 16A,B, 19 A,Bp, 21, 22p, and 23) are predominantly found in the parasite; 4 components (13i, 19A,Bi, 22A, B, and 24) are unique to the membrane of infected erythrocytes. Only three parasite-specific components (1, 13, and 19) are exposed on the surface of parasitized erythrocytes as revealed by both lactoperoxidase-catalyzed radioiodination and extensive absorption of anti-schizont Ig using intact infected erythrocytes. Two plasmodium-specific antigens (1 and 13) on the surface of infected erythrocytes are recognized by sera of rhesus monkeys rendered naturally immune against P. knowlesi infections and, therefore, represent antigens in vivo. Analyses of schizonts and membranes of parasitized erythrocytes of the two different strains of P. knowlesi yields only some minor quantitative, but no qualitative differences when analyzed with both types of antisera. Importantly, components 1 and 13 appear identical in both strains.
Modelling and performance analysis of pre-emption based radio admission control scheme for video conferencing over LTE (2014)

We perceive emerging developments in information and communication technologies (ICTs) in various areas of our dynamic live. The concept of getting services and applications “any time” and “any place” imposes the corresponding development in cellular networks. The rapid worldwide deployment of 4G LTE networks and increasing demand for new services are the key ICT trends that highlight the need for future improvements in technologies underling LTE. Although 3GPP concentrates all standardization activities in LTE, ITU-T recommendations reflect the main quality of service (QoS) requirements in ICTs. Nevertheless, not all QoS related ITU-T recommendations (i.e. E.800–E.899, G.1000–G.1999, Y.1500–Y.1599, Y.2100–Y.2199 series) correspond to today's variety of products and services provided by cellular networks. This fact raises the need for updates in these recommendations. In this paper, we explore QoS measures specific to LTE services adaptively occupying radio resources. This so-called pre-emption process assumes the service degradation as well as service interruption. We propose a pre-emption based radio admission control (RAC) model for two resource demanding video services - video conferencing and video on demand. We apply teletraffic and queuing theories to get a recursive algorithm for calculating its performance measures, namely, blocking probability, pre-emption probability, and mean bit rate

A New Annulation Reagent, 2-Oxo-3-alkenylphosphonates. Reactions with Carbonyl-Stabilized Carbanions or Silyl Enol Ethers Leading to Cyclohexenones (1992)

Abstract The reactions of 2-oxo-3-alkenylphosphonates with carbonyl-stabilized carbanions directly lead to 2-cyclohexen-1-ones through a sequence of Michael reaction and intramolecular Horner–Emmons olefination. On the other hand, the Lewis acid-mediated reactions with silyl enol ethers produce 1,5-diketones as Michael adducts, which then undergo cyclization on treatment with sodium hydride or triethylamine/zinc (II) bromide to afford 2-cyclohexen-1-ones or 2-phosphinyl-2-cyclohexen-1-ones, respectively.
Naturalised Dyes: A Simple Straightforward Synthetic Route to a New Class of Dyes – Glycoazodyes (GADs) (2006)

Abstract We report a process to naturalise synthetic azodyes through their linkage with lactose, or its monosaccharide components, either galactose or glucose, to enhance their solubility, as many other natural dyes. This modification allows the dyeing process of textile materials to take place in water without the addition of surfactants or other additives. The synthesis of the first generation of glycoazodyes (GADs) is carried out with the use of a diester linker to bond the azodye and the sugar. Preliminary tinctorial tests showed that this first generation of GADs is soluble in water and that these new dyes are multipurpose and are able to dye different fabrics well.(© Wiley‐VCH Verlag GmbH & Co.

Playing soccer with legged robots (2002)

Sony has provided a remarkable platform for research and development in robotic agents, namely fully autonomous legged robots. In this paper, we describe our work using Sony's legged robots to participate at the RoboCup'98 legged robot demonstration and competition. Robotic soccer represents a very challenging environment for research into systems with multiple robots that need to achieve concrete objectives, particularly in the presence of an adversary. Furthermore RoboCup'98 offers an excellent opportunity for robot entertainment. We introduce the RoboCup context and briefly present Sony's legged robot. We developed a vision-based navigation and a Bayesian localization algorithm. Team strategy is achieved through pre-defined behaviors and learning by instruction.

Single input current-sensing differential logic (SCSDL) (2000)

A new novel single input current-sensing differential logic (SCSDL) is proposed. The SCSDL is flexible-in particular high input Boolean logic functions can be implemented with low complexity, area consumption, time delay, and power consumption. The first part of the area saving comes from the remarkable reduction of wiring; the other part comes from the very low number of transistors needed to implement a complex Boolean function, compared with other types of logic (e.g. CRDL, CSDL, DCVSL, static logic). Since this logic relies on comparison of currents in two branches, mismatch could ruin the function. The yield of the logic is good for a high performance process referred to mismatch.
Recyclable Diels–Alder Furan/Maleimide Polymer Networks with Shape Memory Effect (2014)

A series of recyclable networks with shape memory effect was prepared by the Diels–Alder reaction between furan-functionalized poly(hydroxyaminoethers) (PHAEs) and 1,5-bis(maleimido)-2-methylpentane (MPDBMI). Compression molding was used to recycle the MPDBMI/PHAE films. The Diels–Alder and retro-Diels–Alder reactions between PHAEs and MPDBMI were confirmed by Fourier transform infrared, differential scanning calorimetry (DSC), and solubility test. Furthermore, the mechanical properties and shape memory properties of the original and recycled MPDBMI/PHAE networks were systematically investigated by a tensile test and a quantitative shape memory evaluation method, respectively. DSC measurement indicated that the retro-Diels–Alder reaction will occur upon heating, and the solubility test showed that the recycled MPDBMI/PHAE films may still be considered as recyclable. Moreover, the tensile test at room temperature disclosed that both the original and recycled MPDBMI/PHAE networks exhibited tough properties: all specimens exhibited either the ductile plastic fracture feature with the appearance of yielding phenomenon or the rubber property with large elongation at break. Quantitative shape memory evaluation revealed excellent shape memory performance of the original and recycled MPDBMI/PHAE networks.
Widely Tunable 4th Order Switched G$_m$-C Band-Pass Filter Based on N-Path Filters (2012)

A widely tunable 4th order BPF based on the subtraction of two 2nd order 4-path passive-mixer filters with slightly different center frequencies is proposed. The center frequency of each 4-path filter is slightly shifted relative to its clock frequency (one upward and the other one downward) by a <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">gm</i> -C technique. Capacitive splitting of the input signal is used to reduce the mutual loading of the two 4-path BPFs and increase their quality factors. The filter is tunable from 0.4 GHz to 1.2 GHz with approximately constant bandwidth of 21 MHz. The in-band 1-dB compression point of the filter is -4.4 dBm while the in-band IIP <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> of the filter is +9 dBm and the out-of-band IIP <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> is + 29 dBm (Δ <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">f</i> =+50 MHz). The ultimate rejection of the filter is >; 55 dB and the NF of the filter is 10 dB. The static and dynamic current consumption of the filter are 2.8 mA from 2.5 V and 12 mA from 1.2 V, respectively (at 1 GHz). The LO leakage power to the input port is <; - 60 dBm. The filter has been fabricated in CMOS LP 65 nm technology and the active area is 0.127 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> .
Optimal joint linear acoustic echo cancelation and blind source separation in the presence of loudspeaker nonlinearity (2009)

Acoustic echoes represent a major source of discomfort in hands free, full-duplex, communication systems. The problem becomes particularly difficult when the loudspeakers are nonlinear as considered in this paper. In contrast to the single-microphone linear and nonlinear acoustic echo cancellation techniques, we take advantage of the spatial diversity offered by the microphone arrays. Indeed, having a set of microphones and multiple sources (i.e., the near and far ends) that can be active at the same time, this problem can be solved using a blind source separation (BSS) algorithm. The performance of the BSS can be further improved when combined with a linear acoustic echo canceler (LAEC). In this paper, we study the potentials of joint BSS and LAEC to cancel the echo signals in two schemes. In the first scheme, the BSS is deployed as a front-end and has a twofold function: reducing the acoustic echo and creating a linearly transformed echo reference that is used by the LAEC as a post-processor. In the second scheme, the BSS operates on multiple LAECs outputs to further reduce the residual echo from the target signal. We show that the first scheme outperforms the second one.
Millimetre‐wave waveguide reflectometers for early detection of skin cancer (2013)

Millimetre‐wave (mm‐wave) reflectometry is an efficient technique for diagnosis of human tissue disease such as early stage skin cancer. Two sets of non‐invasive and in‐package reflectometers operating at 42 and 70 GHz are designed, fabricated and successfully tested with different kinds of samples. The tests are performed for a number of liquids, and pure water at different temperatures. Also, the proposed WR‐22 device is tested over skin at different locations. The clinical trial tests are performed on a number of volunteer patients who suffered from Basal cell carcinoma. The proposed devices are easy‐to‐fabricate, and provide a low‐cost solution for fast and accurate skin cancer detection. Furthermore, the proposed technology has the potential to be used for fast tissue inspection during a surgery
Reversible Chain Transfer between Organoyttrium Cations and Aluminum: Synthesis of Aluminum‐Terminated Polyethylene with Extremely Narrow Molecular‐Weight Distribution (2006)

Aminopyridinato-ligand-stabilized organoyttrium cations are accessible in very good yield through alkane elimination from trialkyl yttrium complexes with sterically demanding aminopyridines, followed by abstraction of one of the two alkyl functions using ammonium borates. At 80 degrees C and in the presence of small amounts of aluminum alkyl compounds, very high ethylene polymerization activities are observed if very bulky aminopyridinato ligands are used. During these polymerizations a reversible polyethylene chain transfer is observed between the organoyttrium cations and aluminum alkyls. The chain-transfer catalyst system described here is able to produce relatively long-chain (up to 4000 g mol-1) Al-terminated polyethylene with a molecular-weight distribution<1.1. In the synthesis of higher molecular PE a slight increase in polydispersity with increasing chain length (15,600 g mol-1, approximately 1.4) is observed owing to reduced reversibility caused by higher viscosity and precipitation of polymer chains (temperature of 80-100 degrees C).

Model-based Scatter Correction For Fully 3D PET (2005)

A method is presented that directly calculates the mean number of scattered coincidences in data acquired with fully 3D positron emission tomography (PET). This method uses a transmission scan, an emission scan, the physics of Compton scatter, and a mathematical model of the scanner in a forward calculation of the number of events for which one photon has undergone a single Compton interaction. The distribution of events for which multiple Compton interactions have occurred is modelled as a linear transformation of the single-scatter distribution. Computational efficiency is achieved by sampling at rates no higher than those required by the scatter distribution and by implementing the algorithm using look-up tables. Evaluation studies in phantoms with large scatter fractions show that the method yields images with quantitative accuracy equivalent to that of slice-collimated PET in clinically useful times.

Flux-weakening control of PMSM based on single current regulator and variable q-axis voltage (2012)

Flux-weakening control of PMSM based on single current regulator has high dynamic performance. But the fixed given q-axis voltage decreases the motor's efficiency and load capability. This paper gives a new method of variable q-axis voltage. It can adjust q-axis voltage fully using the motor DC voltage to make motor working at the optimal operating points. It makes the motor efficiency and improves load capability. This method is easy to achieve and does not depend on motor parameters. The results of simulation and experiment verify the method in this paper.
Note: A simple detection method for helium droplet spectroscopy experiments (2017)

Helium droplet methods are currently established as a premier experimental technique for the production and spectroscopic study of novel clusters and complexes. Unfortunately, some of the essential equipment required to perform the experiments, such as the detector used to monitor photon-induced depletion of the helium droplet beam, can be relatively large, complex, and expensive. Most often this detector is a quadrupole mass spectrometer (QMS). In this report, we describe the development and evaluation of an extremely simple, straightforward, small, and inexpensive droplet beam detector for use in helium droplet spectroscopy experiments and compare its performance to that of a QMS by recording the infrared spectra of helium droplets doped with either <sup>13</sup>CO<sub>2</sub> or CD<sub>4</sub>.
Compressive sensing in a photonic link with optical integration (2014)

In this Letter, we present a novel structure to realize photonics-assisted compressive sensing (CS) with optical integration. In the system, a spectrally sparse signal modulates a multiwavelength continuous-wave light and then is mixed with a random sequence in optical domain. The optical signal passes through a length of dispersive fiber, the dispersion amount of which is set to ensure that the group delay between the adjacent wavelength channels is equal to the bit duration of the applied random sequence. As a result, the detected signal is a delay-and-sum version of the randomly mixed signal, which is equivalent to the function of integration required in CS. A proof-of-concept experiment with four wavelengths, corresponding to a compression factor of 4, is demonstrated. More simulation results are also given to show the potential of the technique.

The Central Role of Arginine Catabolism in T-Cell Dysfunction and Increased Susceptibility to Infection After Physical Injury (2013)

Arginine availability is decreased after PI coinciding with an induction of MDSC expressing arginase 1. Decreased arginine may inhibit T-cell function and increase susceptibility to infection after injury.
Effect of Ammonium Concentration on the Emission of N2O Under Oxygen-Limited Autotrophic Wastewater Nitrification (2011)

A significant amount of nitrous oxide (N(2)O), which is one of the serious greenhouse gases, is emitted from nitrification and denitrification of wastewater. Batch wastewater nitrifications with enriched nitrifiers were carried out under oxygen-limited condition with synthetic (without organic carbon) and real wastewater (with organic carbon) in order to find out the effect of ammonium concentration on N(2)O emission. Cumulated N(2)O-N emission reached 3.0, 5.7, 6.2, and 13.5 mg from 0.4 l of the synthetic wastewater with 50, 100, 200, and 500 mg/l NH(4)(+)-N, respectively, and 1.0 mg from the real wastewater with 125 mg/l NH(4)(+)-N. The results indicate that N(2)O emission increased with ammonium concentration and the load. The ammonium removal rate and nitrite concentration also increased N(2)O emission. Comparative analysis of N(2)O emission from synthetic and real wastewaters revealed that wastewater nitrification under oxygen-limited condition emitted more N(2)O than that of heterotrophic denitrification. Summarizing the results, it can be concluded that denitrification by autotrophic nitrifiers contributes significantly to the N(2)O emission from wastewater nitrification.
Use of temporal information: detection of periodicity, aperiodicity, and pitch in speech (2005)

In this paper, we present a time domain aperiodicity, periodicity, and pitch (APP) detector that estimates 1) the proportion of periodic and aperiodic energy in a speech signal and 2) the pitch period of the periodic component. The APP system is particularly useful in situations where the speech signal contains simultaneous periodic and aperiodic energy, as in the case of breathy vowels and some voiced obstruents. The performance of the APP system was evaluated on synthetic speech-like signals corrupted with noise at various levels of signal-to-noise ratio (SNR) and on three different natural speech databases that consist of simultaneously recorded electroglottograph (EGG) and acoustic data. When compared on a frame basis (at a frame rate of 2.5 ms) the results show excellent agreement between the periodic/aperiodic decisions made by the APP system and the estimates obtained from the EGG data (94.43% for periodicity and 96.32% for aperiodicity). The results also support previous studies that show that voiced obstruents are frequently manifested with either little or no aperiodic energy, or with strong periodic and aperiodic components. The EGG data were used as a reference for evaluating the pitch detection algorithm. The ground truth was not manually checked to rectify or exclude incorrect estimates. The overall gross error rate in pitch prediction across the three speech databases was 5.67%. In the case of synthetic speech-like data, the estimated SNR was found to be in close proportion to the actual SNR, and the pitch was always accurately found regardless of the presence of any shimmer or jitter.
