A high acuity 3-D acoustic imaging system (2002)

The N+N imaging system solves the problem of controlling 2-D arrays with only as many control channels as there are rows and columns of elements in the acoustic array. A 10,000 element array can be controlled with only 200 control channels; a reduction in complexity that allows the possibility of a commercial medical acoustic imaging system capable of rapid 3-D, volume, images and/or real time, arbitrary scan plane, 2-D sector, planar, or curve planar images. In addition, it allows the implementation of multi-dimensional aberration correction which may allow ultrasonic images to finally approach the image acuity of MRI and X-ray CAT imaging systems, and to do so at a fraction of the costs of these imaging modalities.
Dynamic link between ECG and clinical data by a CORBA-based query engine and temporal mapping. (1997)

It is important to create a dynamic link method to link distributed patient data across multiple hospitals on an "as needed" basis because the pre-defined links (an item of data has a character or group of characters that indicates the storage of another item of data) are difficult to be managed, or can only be established in part, or are not necessary to be pre-defined in many cases, especially in linking the descriptive data such as history data with the corresponding examination data across multiple hospitals. A method of linking electrocardiogram (ECG) with clinical data dynamically in a Common Object Request Broker Architecture (CORBA) environment has been achieved and verified in a real computing environment to approach to this goal. By this method, distributed patient data can be linked dynamically by a CORBA-based query engine and temporal mapping no matter where they are located on the Internet. The necessary temporal information is provided by either computing or human being. Since multiple time-axes for different databases are involved in, some temporal reasoning methods (such as mapping occurrences across temporal contexts and determining bounds for absolute occurrences, etc.) are applied to this study, and a series of temporal mappings including the first mapping, the secondary mapping, the contextual mapping, the extended mapping, the previous mapping and the next mapping are created. In comparison with the pre-defined link, the major strengths of this method are the dynamic link on an "as needed" basis, no limitation of institutional boundaries, easy creation, simplifying the data storage, and the high flexibility, etc.
Clustering-based Approach to Multiword Expression Extraction and Ranking (2015)

We present a domain-independent clusteringbased approach for automatic extraction of multiword expressions (MWEs). The method combines statistical information from a general-purpose corpus and texts from Wikipedia articles. We incorporate association measures via dimensions of data points to cluster MWEs and then compute the ranking score for each MWE based on the closest exemplar assigned to a cluster. Evaluation results, achieved for two languages, show that a combination of association measures gives an improvement in the ranking of MWEs compared with simple counts of cooccurrence frequencies and purely statistical measures.
Identification, Prediction and Control of Aero Optical Wavefronts in Laser Beam Propagation (2011)

This paper describes linear time-invariant optimal prediction and control of aero-optical wavefronts derived from recent ight-test data. The optimal controller is based on an optimal prediction lter that has the form of a multi-input-multi-output state-space model that captures the statistics of the aero-optical wavefront sequence. Experimental result in the paper show the improvement in wavefront correction achieved by an optimal controller based on the identied prediction lter, as opposed to a classical adaptive optics loop.
Supramolecular Polymers Formed by ABC Miktoarm Star Peptides (2013)

We report here the design and synthesis of an ABC miktoarm star peptide connecting through a lysine junction a short peptide sequence and two hydrophobic but immiscible blocks (a hydrocarbon and a fluorocarbon). The designed molecule can self-assemble into one-dimensional nanostructures with a great diversity of kinetically evolving morphologies in aqueous solution, while molecules that contain only one of the two hydrophobic blocks form structurally similar filaments. We believe the rich assembly behavior and morphological evolution are a direct reflection of the molecular frustration present within the filament core as a result of the in-compatibility of the fluorocarbon and hydrocarbon segments. Our finding opens new opportunities for creating complex supramolecular polymers through the architecture design of small molecular building units.

GRUNDLAGEN DER EUROPAEISCHEN UNION (1995)

Seit dem 1.11.1993 ist der Vertrag ueber die Europaeische Union in Kraft, der unter anderem die Verwirklichung von Artikel 74 (Gemeinsame Verkehrspolitik) des EG-Vertrages bestaetigt. Die erforderlichen Massnahmen sind in Artikel 75 enthalten, der zitiert und interpretiert wird. Vorrangig werden einheitliche Standards fuer die Zulassung von Personen und Fahrzeugen zu entwickeln sein. In diesem Zusammenhang ist die Einfuehrung des einheitlichen europaeischen Fuehrerscheins ab 1996 zu sehen, wobei noch keine Einigung besteht hinsichtlich der Mindestanforderungen an Fahrausbildung und -pruefung. Bei den Zielen kuenftiger Verkehrspolitik in Europa wird es darum gehen, den gemeinsamen Markt auch fuer die Transportwirtschaft herzustellen. Qualitativ muss das Verkehrssystem staerker als bisher auf Sozial- und Umweltvertraeglichkeit ausgerichtet werden. Verkehrsvermeidung scheint bisher einen voellig untergeordneten Stellenwert zu haben. Siehe auch Gesamtaufnahme des Handbuches, IDS-Nummer 334763.
Secure in-vehicle systems against Trojan attacks (2015)

Recently, driving support technologies, such as inter-vehicle and road-to-vehicle communication technologies, have been practically used. However, a problem has been pointed out that when a vehicle is connected with an external network, the safety of the vehicle is threatened. As a result, the security of vehicle control systems, which greatly affects vehicle safety, has become more important than ever. Ensuring the security of in-vehicle systems becomes an important priority, similar to ensuring conventional safety. The present study proposes a controller area network (CAN) communications method that uses a lightweight cipher to realize secure in-vehicle systems. The present study also constructs an evaluation system using a field-programmable gate array (FPGA) board and a radio-controlled car. This is used to verify the proposed method.
Microwave-induced DC Signal in a Permalloy Thin Strip at Low Applied Magnetic Field (2011)

We investigated the ferromagnetic resonance signals in a polycrystalline permalloy thin strip under in-plane low static magnetic field. A series of DC voltages, which contain ferromagnetic resonance or spin wave resonance signals, were measured by inducing microwave frequencies greater than 10 gigahertz. The resonant signals measured in low magnetic field show different properties from those detected in high field condition. Based on the theory of DC effects in ferromagnetic resonance and the experimental data of anisotropic magnetoresistance, a quantitative model was proposed. We found that the shape anisotropy significantly affects magnetization, and distorts the resonant signals in low field condition.
Application of Piperazine-Derived Hydrazone Linkers for Alkylation of Solid-Phase Immobilized Ketones (2002)

The preparation and application of three new solid supports with piperazine-derived hydrazine anchoring groups are described. The supports were used for immobilization of ketones. The ketones: cyclohexanone, 4-tert-butylcyclohexanone, 3-pentanone and tropinone, which were bound to polymers in the form of their hydrazones, were deprotonated with LDA and alkylated with propyl iodide or benzyl bromide. The resulting alkylated products were cleaved off the solid support on treatment with trifluoroacetic acid in dichloromethane. Linkers with 6- and 3-carbon atom spacers gave better results than the simple N-aminopiperazine linker.
Influence of Active Channel Layer Thickness on SnO2 Thin-Film Transistor Performance (2021)

Sol-gel processed SnO2 thin-film transistors (TFTs) were fabricated on SiO2/p+ Si substrates. The SnO2 active channel layer was deposited by the sol-gel spin coating method. Precursor concentration influenced the film thickness and surface roughness. As the concentration of the precursor was increased, the deposited films were thicker and smoother. The device performance was influenced by the thickness and roughness of the SnO2 active channel layer. Decreased precursor concentration resulted in a fabricated device with lower field-effect mobility, larger subthreshold swing (SS), and increased threshold voltage (Vth), originating from the lower free carrier concentration and increase in trap sites. The fabricated SnO2 TFTs, with an optimized 0.030 M precursor, had a field-effect mobility of 9.38 cm2/Vs, an SS of 1.99, an Ion/Ioff value of ~4.0 × 107, and showed enhancement mode operation and positive Vth, equal to 9.83 V.
Demonstration of a Software Solution to Support OpenConfig and OpenROADM (2019)

A Free Streamline Analysis of Separated Flow in a Centrifugal Impeller (1988)

The flow in a logarithmic impeller with trailing edge separation is analysed by using a conformal mapping method. The problem is linearised by assuming that the thickness of the separated region is small. The flow can be determined by specifying the location of the separation point, and by the application of the condition that there should be no singularity at the closure point. The latter condition results in the location of the closure point shortly downstream of the trailing edge. It is shown that the head is significantly reduced by the separation. Discussions are made about the angular momentum conservation relations for a few models and it is found that the conservation relation is better satisfied for those cases with a thinner separated region, without much dependence on the model used.
El dopaje en los deportes de contacto (2006)

El riesgo que supone el consumo de sustancias dopantes supera al beneficio que aporta al deportista. El exito deportivo no solo se consigue con sacrifico y superacion personal, actualmente existe tambien otra arma eficaz y mortifera para el organismo: el empleo de sustancias dopantes. El dopaje es la utilizacion de sustancias o metodos para mejorar el rendimiento y evitar la fatiga del deportista, cuya utilizacion esta prohibida en el deporte federado. Cualquier deportista debe saber exactamente que es lo que se entiende por dopaje en el deporte, sin que le quede ninguna duda al respecto y conocer perfectamente sus consecuencias.
Study of Ni-Silicide Contacts to Si:C Source/Drain. (2006)

Integration of recessed Si:C source/drain (S/D) for deep sub- micron nMOSFET devices results in substantial improvement of electron mobility and drive current due to introduction of tensile strain in the channel. The compatibility of Ni-silicide contacts with Si:C source/drain is investigated in this paper. The Ni-silicide morphology and phase formation were studied by means of sheet resistance measurements, X-Ray Diffraction (XRD) and Energy Dispersive Spectroscopy (EDS) analysis, Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) inspection. The carbon concentration and profile in the NiSi:C film was studied by Secondary Ion Mass Spectrometry (SIMS) analysis. The strain in the Si:C substrate and NiSi:C film was studied by high resolution XRD (HRXRD). This paper demonstrates that Ni-silicide is compatible with Si:C. The tensile strain in Si:C is maintained after Ni-silicidation. The addition of carbon to silicon is found to stabilize the silicide morphology.

Transactional issues in distance education: The impact of design in Audioteleconferencing (1995)

Abstract This paper reports the results of a study of student perceptions of learning via audioconferencing in university‐level courses delivered at a distance. Field observations, interviews, and a focus group were used to triangulate and deepen knowledge obtained from an initial mail survey. The results of the investigation revealed that the audioteleconferences were being used under two quite different instructional designs, which were associated with significant differences in students' perceptions of the opportunity to engage in critical thinking skills, creation of a community of inquiry, and the value of various components of the distance education system. The study documents students' perceptions and outlines ways in which these sessions can be designed to induce maximum learning opportunities.

<title>Quantitative Analysis Of Polishing Efficiency Obtained On Standard Machines</title> (1977)

With simple changes, some standard polishing machines can be used to make possible a quantitative analysis of polishing efficiencies. By weighing stock removal of glass under controlled polishing conditions, it is possible to determine the instantaneous efficiency, and its variations as a function of time which is dependent on the nature of the polisher, the concentration and temperature of the slurry, the pressure and speed of the spindle. This test has been very useful for the development of a range of new polishing products differentiated according to the principal type of polishers. It is also employed to control the quality of the manufacture and to guide users in their choice of the best product for a specific application. Some practical examples are described.
Sinusoidal Anti-coupling SOI Strip Waveguides (2015)

We experimentally demonstrate sinusoidal anti-coupling silicon-on-insulator strip waveguides, separated by 200 nm, that have a minimum inter-waveguide crosstalk suppression of 26.8 dB within the C-band for the fundamental transverse electric mode.
Aerodynamic characteristics of low-drag bicycle wheels (1995)

Abstract A number of modern “aerodynamic” bicycle wheels were tested at full scale speeds in a windtunnel. The effects of wheel geometry, rotational speed and cross winds on drag force, side force and yawing moment were investigated. Compared with a conventional spoked wheel, all the “aerodynamic” wheels were found to give similar improvements in drag of approximately 25%. In cross wind conditions, aerodynamic characteristics were strongly dependent on wheel geometry, but essentially independent of wheel rotational speed.
4.1 A 16GHz, $41\text{kHz}_{\text{rms}}$ Frequency Error, Background-Calibrated, Duty-Cycled FMCW Charge-Pump PLL (2023)

FMCW radars are the key components for contactless range and motion sensing in industrial and healthcare applications. The radar-sensor performance, such as chirp bandwidth <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$(\text{BW}_{\mathrm{c}\text{hi}\text{rp}})$</tex> , chirp slope, and frequency-modulation (FM) linearity, are determined by the FMCW chirp generator. When battery powered, the radar should be able to operate in a duty-cycled mode with minimal overhead, i.e., fast startup, fast lock at the start of every chirp burst, and minimal reset time in-between chirps, without degrading the radar range and Doppler performance. This work presents a robust fast-lock-acquisition charge-pump (CP)-PLL with a PFO for duty-cycled chirp generation. A fractional-N CP-PLL in a two-point-modulation (TPM) architecture breaks the trade-off between the PLL bandwidth and fast-chirp synthesis [1], [2]. A time-domain sign-extraction by using a 1 b TOC [3] enables the background calibration. A phase-offset-compensating digital-to-time converter (POC-OTC) assists the sign-extraction by compensating the positive/negative phase offsets generated within the type-Il PLL loop.
Identification and enzymatic deglycosylation of the myometrial oxytocin receptor using a radioiodinated photoreactive antagonist. (1991)

To identify and characterize oxytocin receptors, a 125I-labeled photoreactive oxytocin antagonist was synthesized. The specific oxytocin antagonist [1-(beta-mercapto-beta,beta- cyclopentamethylenepropionic acid), 2-O-methyltyrosine,4-threonine,8- ornithine,9-tyrosylamide]oxytocin ([Mca,Tyr(O-Me)2,Thr4,Orn8,Tyr9-NH2]oxytocin) described by Elands et al. (Elands, J., Barberis, C., Jard, S., Tribollet, E., Dreifuss, J.-J., Bankowski, K., Manning, M., and Sawyer, W. H. (1987) Eur. J. Pharmacol. 147, 192-207) bound to the guinea pig uterine oxytocin receptor with high affinity (apparent Kd = 0.74 nM). The introduction of a 4-azidophenylamidino group at Orn8 resulted in the photoreactive ligand [Mca1,Tyr(O-Me)2,Thr4,Orn(4-azidophenylamidino)8,Tyr9- NH2]oxytocin, which retained the high binding affinity (Kd = 0.69 nM) of the parent compound. The photoreactive antagonist monoiodinated at Tyr9 had approximately double (Kd = 0.39 nM) the affinity of the photoreactive antagonist and several times that of oxytocin (Kd = 2.6 nM) for the guinea pig uterine oxytocin receptor. In photo-affinity labeling experiments using myometrial membranes obtained from guinea pigs during late pregnancy, the 125I-labeled photoreactive antagonist specifically labeled a protein with an apparent molecular mass of between 68 and 80 kDa: the labeling of this protein was completely suppressed by a 100-fold molar excess of oxytocin and oxytocin receptor-specific agonists, but not by vasopressin analogues specific for V1 or V2 receptors or by other peptide hormones. The ability of oxytocin to suppress labeling was decreased in the presence of guanosine 5'-O-(thiotriphosphate) or in the absence of Mn2+. Digestion of the photolabeled oxytocin receptor with endoglycosidase F gave rise to a protein with an apparent molecular mass of 38 +/- 2 kDa. The endoglycosidase F effect and the lack of endoglycosidase H action show that the myometrial oxytocin receptor is highly glycosylated with asparagine-linked complex oligosaccharide chains. Our results suggest that the radioiodinated photoreactive oxytocin antagonist could be a helpful tool in the isolation and further characterization of the oxytocin receptor.
The effect of growth hormone administration on human sleep: a dose-response study. (1980)

Human growth hormone and saline were administered for one night each to normal volunteers in a cross-over study. A dose of 2 units im given 15 min before bedtime had no effect on sleep EEG parameters. In contrast, 5 units resulted in a 19% decrease in slow-wave sleep (p < 0.01) and a 13% increase in REM sleep (p < 0.05). Neither doe, when given during daytime, affected tests of affect or serial learning.
A multiplexed two-wave mixing interferometer for laser ultrasonic measurements of material anisotropy (2002)

A method to optically measure ultrasonic displacements simultaneously over an array of detection points has been developed. Optical phase gratings are used to create a detection-array of laser beams that are directed to the specimen. The detection array can be arranged in several ways on the test object. The scattered beams from the detection-array are collected and combined with a single reference beam in a photorefractive crystal to from a multiplexed two-wave mixing (MTWM) configuration. Each of the output beams from the photorefractive crystal is imaged on to a separate element of a photodetector array. The resulting MTWM system is capable of providing simultaneous optical detection (with high spatial resolution and sub-nanometer displacement sensitivities) at several points on a test object. The MTWM system can be used in several modes for laser ultrasonic NDE of flaws and materials characterization. In this paper, the MTWM is used to characterize material anisotropy. Surface acoustic waves (SAWs) are generated using a pulsed laser focused to a point on a test object. The resulting SAW propagation is monitored optically simultaneously at 8 points arranged circularly around the generating spot. The scattered beams from the eight detection points are processed simultaneously in the MTWM setup. The group velocity slowness curve is obtained directly from the measured signals from the MTWM array. Results are shown for silicon and quartz. It is shown that the MTWM enables rapid experimental determination of material anisotropy.
