					surpluses of the companies.
Structure-based design of <i>Taq</i> DNA polymerases with improved properties of dideoxynucleotide incorporation (1999)

The Taq DNA polymerase is the most commonly used enzyme in DNA sequencing. However, all versions of Taq polymerase are deficient in two respects: (i) these enzymes incorporate each of the four dideoxynucleoside 5' triphosphates (ddNTPs) at widely different rates during sequencing (ddGTP, for example, is incorporated 10 times faster than the other three ddNTPs), and (ii) these enzymes show uneven band-intensity or peak-height patterns in radio-labeled or dye-labeled DNA sequence profiles, respectively. We have determined the crystal structures of all four ddNTP-trapped closed ternary complexes of the large fragment of the Taq DNA polymerase (Klentaq1). The ddGTP-trapped complex structure differs from the other three ternary complex structures by a large shift in the position of the side chain of residue 660 in the O helix, resulting in additional hydrogen bonds being formed between the guanidinium group of this residue and the base of ddGTP. When Arg-660 is mutated to Asp, Ser, Phe, Tyr, or Leu, the enzyme has a marked and selective reduction in ddGTP incorporation rate. As a result, the G track generated during DNA sequencing by these Taq polymerase variants does not terminate prematurely, and higher molecular-mass G bands are detected. Another property of these Taq polymerase variants is that the sequencing patterns produced by these enzymes are remarkably even in band-intensity and peak-height distribution, thus resulting in a significant improvement in the accuracy of DNA sequencing.

Study on selectivity enhancement of tin dioxide gas sensor using non-conducting polymer membrane (2002)

A non-conducting polymer membrane can be used as a molecular sieve to enhance the selectivity of a tin dioxide gas sensor. A commercial polymer, polyimide XU218 of the Eiba-Geigy company, is coated on the surface of a tin dioxide gas sensor FIGARO TGS842 which was designed to detect methane. The polymer coated sensor is calibrated in a high accuracy testing system which is controlled by a PC with GPIB and mass flow controllers (MFCs). Three gases, hydrogen, methane, and ammonia, are used to investigate the response of the sensor. It is found that the sensor shows a characteristic change in response to ammonia and an almost negligible change in response to hydrogen and methane.
Electrochemical Water Splitting at Bipolar Interfaces of Ion Exchange Membranes and Soils (2002)

Under the influence of a direct current, the dissociation rate of water in contact with bipolar ion exchange membranes (BPMs) is 10 6 to 10 7 times faster than in free solution. This phenomenon, termed accelerated water splitting , is well known in industry where BPMs are designed for electrosynthesis of acids and bases. In this work, it is hypothesized that (i) accelerated water splitting can also take place at the bipolar interface between ion exchange membranes (IEMs) and the ion exchange surfaces of soils, and (ii) electroosmosis plays a key role. If the IEM has an electrostatic charge opposite in sign to the predominant charge on the soil colloidal particles, the interface is, in effect, bipolar. If an external electric field is then applied, conditions can give rise to accelerated water splitting. Laboratory experiments performed on various mixtures of Ottawa sand, bentonite, talc, and anion exchange resin indicate that accelerated water splitting occurs when the free pore solution in the low permeable soil moves away from the bipolar interfaces due to electroosmosis, thus causing an unsaturated zone at these interfaces. Accelerated water splitting then initiates at these interfaces since there are not enough counterions in contact with the IEMs to maintain an ionic current. Very little cation exchange capacity (CEC), anion exchange capacity (AEC), or clay is needed for water splitting to occur at a bipolar IEM and soil interface.
Fresnel-Volume-Migration of Single-Component Seismic Data (2006)

In standard KPSDM implementations of Kirchhoff prestack depth migration (KPSDM) the wavefield is smeared along two-way-traveltime isochrones. In the case of sparse sampling or limited aperture the image is sometimes affected by significant migration noise. Some modifications have been proposed which aim at reducing these artefacts by constructing a specular path of wave propagation derived from the slowness of coherent phases in the seismogram section and the heuristic restriction of the imaging operator to that wave path. Here we propose another physically frequency-dependent approach by using the concept of Fresnel-Volumes. Firstly the emergence angle at the receiver is determined by a local slowness analysis. Using the emergence angle as the starting direction a ray is propagated into the subsurface and the back-propagation of the wavefield is restricted to the vicinity of this ray according to its approximated Fresnel-Volume. We describe the procedure and show applications to a synthetic model as well as a real data set over a salt pillow in North Germany. Compared with standard KPSDM the image quality of our Fresnel-Volume-Migration is significantly enhanced due to the restriction of the migration operators to the region near the actual reflection point.
Dynamic network configuration management (1990)

Configuration and traffic management for reconfigurable networks is investigated. Such networks have the potential to adapt well to changing traffic patterns and to failure of physical facilities. The authors define the underlying constrained optimization problem in general, and apply a heuristic technique to a simple case to illustrate the benefit of reconfiguring the logical network. It is found that reconfiguration results in substantial improvements in the blocking performance of the network when it is subjected to uneven loading. The authors compare and contrast reconfiguration with a dynamic alternate routing scheme, concluding that the two techniques together provide the best performance. Technology and systems issues relevant to managing such reconfigurable networks are discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Purification and Properties of the Glucose Oxidase from Aspergillus niger (1965)

Glucose oxidase (/3-n-glucose : 02 oxidoreductase, EC 1.1.3.4) has been highly purified from the extracts of three fungi, Penicillium not&urn (1, 2), Penicillium amagasakiense (3, 4), and Aspergillus niger (5, 6).It has also been identified and sometimes partially purified from a number of other sources.Some of these sources are reviewed by Schepartz and Subers (7).Recently Pazur and Kleppe ( 6) have studied the specificity, and Gibson, Swoboda, and Massey (8, 9), the kinetics and mode of action, of the glucose oxidase from A. niger.Pazur, Kleppe, and Ball (10) have made the interesting discovery that this enzyme is a glycoprotein.It has generally been assumed that the glucose oxidases from different sources have the same properties.In this paper some of the physical and chemiral properties of t)he enzyme purified from A. niger are examined and compared with published data for glucose oxidases from other fungal sources.It is felt that the properties of the glucose oxidases isolated from P. not&urn (2, 11) and P. amagusakiense (4, 12) are sufficiently different from those of the il.niger enzyme to warrant more detailed intercomparison in the future.EXPERIMEiW.4LPROCEDURE Xaterials-Dee-O-Concentrate, an extract of .,I. niger mycelia (13), was obtained from the Takamine Laboratories, Miles Chemical Company, New *Jersey.n-Amino acid oxidase was prepared from fresh hog kidneys (14).Catalase with 1260 Keilin units per g was obtained from L.

French large vocabulary recognition with cross-word phonology transducers (2002)

Although finite-state transducers have been widely used in linguistics, their application to speech recognition has begun only recently (M. Mohri, 1997). We describe our implementation of French large vocabulary recognition based on transducers, and how we take advantage of this approach to integrate automatic pronunciation rules and cross-word phenomena such as French "liaison". We also show that a simple, single-level Viterbi algorithm can efficiently decode speech recognition transducers and handle cross-word context models and cross-word phonological rules. In our experiments we compared network size, error rate and decoding speed of our transducer based recognizer against a baseline HTK recognizer, on a large vocabulary French dictation task. Transducers reduced search time by a factor of 25 compared to our HTK recognizer. We also examined the effect of automated pronunciation rules, and their combination with crossword phonological rules that control "liaison". We obtained a 23% relative reduction in the word error rate on a 5000 word task.
Beta-Adrenergic receptor interactions. Characterization of iodohydroxybenzylpindolol as a specific ligand. (1976)

Hydroxybenzylpindolol (HYP) is a specific and highly potent beta-adrenergic antagonist. Monoiodination of HYP produces an equally high affinity inhibitor of binding to and activation of the beta receptor-coupled adenylate cyclase in turkey erythrocyte membranes. Monoiodohydroxybenzylpindolol was isolated by high pressure liquid chromatography. Mass spectroscopy showed that the iodine was contained in the phenolic moiety of the molecule. 125I-HYP was purified in tracer amounts by ion exchange chromatography; specific activities were achieved (1500 to 2000 Ci/mmol) approaching theoretical for 1 mol of iodine/mol of HYP. 125I-HYP interacts with a single stereospecific site with affinity of 4 to 5 X 10(10) M-1 by Scatchard analysis. Maximal binding capacity was 0.2 to 0.3 pmol/mg of membrane protein. If recovery of receptor were complete, this would correspond to 400 to 600 receptor sites per cell. Kinetic analyses of the on and off reactions gave a kinetically derived KA in good agreement with that derived from thermodynamic methods both at 20 degrees and 37 degrees. No evidence is found in these experiments for cooperative interaction of ligands with the receptor system. Iodohydroxybenzylpindolol thus represents a high affinity, high specific activity ligand of established chemical structure which should prove useful in studying the interaction of other blockers and agonists with the beta-adrenergic receptor in this and other biological systems.
Hardware architectures of adaptive equalizers for the HDTV receiver (1998)

This paper proposes hardware architectures of adaptive equalizers applicable to both the quadrature amplitude modulation (QAM) and vestigial sideband modulation (VSB) systems. First, adaptive equalization algorithms for QAM and VSB systems are presented by modifying the constant modulus algorithm (CMA) and least mean squares (LMS) algorithm, and their hardware mapping procedure is described. The proposed digitization methods requiring a low hardware cost show performance comparable with that of the algorithm employing floating-point operations. To reduce the hardware cost of the high-definition television (HDTV) equalizers, we propose a pipelined architecture that processes some parallel parts sequentially. The synthesis results by very-high-speed integration circuit (VHSIC) hardware description language (VHDL) show that the proposed architecture reduces the hardware complexity by a factor of two, compared with the architecture designed directly from the equalization algorithms.

A Message Passing Approach to Acquire mm-Wave Channel State Information Based on Out-of-Band Data (2018)

Millimeter-wave (mm-wave) communication is a practicable scheme for big data communication, such as next-generation cellular communication. However, because mm-wave frequencies have an extremely large path loss, in order to mitigate the mm-wave path loss, a large number of antennas are packed for beamforming. Conventional multiple-input multiple-output (MIMO) beamforming uses digital processing, which leads to needing extremely giant energy. Hybrid analog/digital beamforming could serve as an awesome technique to reduce the cost. It is essential for achieving high beamfroming gain that accurate mm-wave channel information should be attained at the transmitter. This paper concentrates on the channel state information (CSI) acquirement problem in mm-wave communication systems with massive MIMO arrays. Because of the CSI acquirement, a method of significant overhead, we consider an accurate channel estimation scheme with low overhead. Not only do we in this paper propose using support information extracted at Sub-6GHz to aid the mm-wave CSI acquirement but also introduce a strategy used in the mm-wave channel estimation. We, in particular, formulate mm-wave CSI acquirement as a compressive sensing problem and obtain the CSI by using Bernoulli-Gaussian generalized approximate message passing (BG-GAMP) algorithm. We also extend the BG-GAMP algorithm with support distribution information from sub-6-GHz channel. Furthermore, based on the K nearest neighbor idea, we redesign the BG-GAMP algorithm depending on sub-6-GHz support distribution information. Details of BG-GAMP with the nearest neighbor learning algorithm that is built on support distribution information from sub-6-GHz channel would also be revealed. Simulation results show the out-of-band information aided mm-wave channel estimation is capable of reducing the pilot overhead greatly and channel estimation accuracy improved as well.

A comparison of Pose Estimation algorithms for Machine Vision based Aerial Refueling for UAVs (2006)

This paper focuses on the analysis of the performance of specific 'detection and labeling' and 'pose estimation' algorithms within a machine vision (MV)-based approach for the problem of autonomous aerial refueling (AAR) of UAVs. A robust 'detection and labeling algorithm' for the correct identification and sorting of the optical markers is proposed; a sorted list of marker positions is then provided as input to the 'pose estimation' algorithm. A detailed study of the performance of two specific 'pose estimation' algorithms (GLSDC and LHM) is performed with special emphasis on the required computational effort as well as on the robustness and error propagation characteristics. Extensive simulation studies demonstrate the performance of the LHM and GLSDC algorithms and show the importance of a robust 'detection and labeling' algorithm. The simulation effort is performed using a detailed modeling of the AAR maneuver according to the USAF refueling method
Anti-interferon antibodies in multiple sclerosis. Molecular basis and their impact on clinical efficacy (2004)

Low levels of naturally-occurring, high-affinity antibodies directed against cytokines can be found in the circulation of individuals who have never been exposed to exogenously-supplied cytokines. These antibodies are thought to play a regulatory role in the intensity and duration of immune response. Interferon (IFN) beta has been shown to attenuate both relapsing-remitting multiple sclerosis (MS) and secondary progressive MS in several well-powered, randomized, controlled clinical trials. IFN therapy can induce the production of anti-IFN neutralizing antibodies (NAb), usually in the second 6 months of treatment, in 3 to 45% of treated patients. This variation in the proportion of NAb-positive patients is probably due to the immunogenicity of different formulations of IFN beta, as well as the assay used, which are not currently standardized. The occurrence of NAb appears to be directly correlated with the dose of therapeutic IFN administered, up to a certain dose threshold. If the dose is increased beyond this threshold, the levels of NAb decrease. The biological significance of anti-IFN NAb is not yet known, nor has it been proven conclusively that they affect the clinical response to IFN beta therapy. The presence of NAb is therefore not an indication that treatment should be changed. Indeed, any treatment decision should be based only on the clinical response to therapy.
Examination of a Mechanical Amplifier in the Incudostapedial Joint Gap: FEM Simulation and Physical Model (2014)

Implantable assembly components that are biocompatible and highly miniaturized are an important objective for hearing aid development. We introduce a mechanical transducer, which could be suitable as part of a prospective fully-implantable hearing aid. The transducer comprises a sensor and an actuator unit in one housing, located in the joint gap between the middle ear ossicles, the incus and stapes. The setup offers the advantage of a minimally invasive and reversible surgical solution. However, feedback between actuator and sensor due to mechanical coupling limits the available stable gain. We show that the system can be stabilized by digital control algorithms. The transducer is tested both in a finite elements method simulation of the middle ear and a physical model of a human middle ear. First, we characterize the sensor and actuator elements separately. Then, the maximum stable gain (MSG) of the whole transducer is experimentally determined in the middle ear model. With digital feedback control (using a least mean squares algorithm) in place, the total signal gain is greater than 30 dB for frequencies of 1 kHz and above. This shows the potential of the transducer as a high frequency hearing aid.
<title>Matching structural images of the human brain using statistical and geometrical image features</title> (1994)

The efficacy of using intensity edges, curvature of iso-intensity contours, and tissue classified data for image matching are examined. The image matching problem is formulated in such a way that the different features are handled uniformly, allowing the same code to be used in each instance. The results using both simulated and real brain images indicate that each feature affected and improvement in the correspondence after matching with it.
Optimal Challenges for Selection (1980)

This paper generalizes the problems of optimal selection considered by Roth, Kadane and DeGroot by allowing a set of J items to be chosen by two decision makers, the first of whom has A challenges and the second has B challenges. The two decision makers each have an opportunity to challenge each item before it is accepted, in some arbitrary fixed order. We assume that the decision makers know the utility function of the other side as well as their own over sets of J items, and that they know the subjective distribution, assigned by the other side, of characteristics of potential items that will be observed, as well as their own. Under these conditions the other side's response to each potential item can be predicted with certainty, and backward induction defines an optimal strategy. We study an important special case we call regular, and show that it is never disadvantageous to go first in the regular case. The use of peremptory challenges in jury trials motivates our model. The basic model in which jurors are challenged one at a time is extended to a more general class of problems that includes the group system and the struck jury system.
Model-Based Tractography Based on Statistical Atlas of MR-DTI (2006)

We have been constructing a statistical atlas of white matter fiber tracts, in which probability density maps of tract structures are stored with diffusion tensor parameters on spatially normalized brain data. The atlas is based on our fiber tract modeling method by using vector/tensor field reconstruction avoiding fiber-crossings. In this abstract, we describe the model-based DTT method by using our statistical atlas, and the preliminary results.

YEAST BLOTTERS: SURVIVAL OF YEAST AND BACTERIA (1982)

The survival of yeast on yeast blotters with and without contaminating bacteria was monitored to determine whether or not microscopic analysis of yeast after shipment on blotters might be influenced by growth of such bacteria. To examine blotter yeast, they were resuspended and roughly balanced to known opacity by colorimeter—then precisely by hemacytometer. Suspensions were then analysed for survival by plating. It was determined that bacteria and yeast both die quickly on blotters but demonstrate varying levels of survival. It was verified that viable counts from blotters are not practical for enumeration purposes although qualitative knowledge can be gained from viable cell assessment.
