The transpacitor, a novel three-terminal MOS-capacitor switching device (1982)

A device is described that operates on the principle of modulation of the displacement current flowing between two outer gate electrodes by a voltage applied to a third intermediate electrode. This electrode is composed of a 0.5 µm electronic-quality silicon layer which can now be prepared by recrystallization processes. The device is switched by biasing this layer either in accumulation or depletion punchthrough. The performance of devices measured thus far has shown good modulation ratios and promising transition speeds. The device is a three-terminal version of a varactor diode so that high speeds and low power dissipation may be expected. Application to logic circuits is discussed.
Deep Reinforcement Learning for Join Order Enumeration (2018)

Join order selection plays a significant role in query performance. However, modern query optimizers typically employ static join order enumeration algorithms that do not incorporate feedback about the quality of the resulting plan. Hence, optimizers often repeatedly choose the same bad plan, as they have no mechanism for "learning from their mistakes." Here, we argue that deep reinforcement learning techniques can be applied to address this challenge. These techniques, powered by artificial neural networks, can automatically improve optimizer decision-making by incorporating feedback. Towards this goal, we present ReJOIN, a proof-of-concept join enumerator, as well as preliminary results indicating that ReJOIN can match or outperform the PostgreSQL optimizer in terms of plan quality and join enumeration efficiency.
Acquisition and Expression of Resistance by Bos indicus and Bos indicus x Bos taurus Calves to Amblyomma americanum Infestation (1985)

Purebred and crossbred Bos indicus calves were infested 1, 2, or 3 times with 10 female and 5 male Amblyomma americanum. Resistance was acquired by both the purebred and the crossbred calves after 1 infestation and resulted in statistically significant decreases in the percentages of females that engorged, the mean weights of engorged females, and the mean weights of egg masses. Comparisons between breeds of the percent of female ticks that engorged during the first and second infestations indicate that purebred B. indicus expressed a stronger acquired resistance to A. americanum more readily than did crossbred animals. However, calves of both genetic compositions displayed similar levels of resistance during a third exposure. All tick-exposed and control animals were skin tested with salivary gland extracts of A. americanum, A. cajennense and Dermacentor andersoni. Control, uninfested calves, did not display significant cutaneous reactivity to these extracts. All calves that had been infested had immediate, 30-min, 5-hr and delayed, 24-hr, skin reactions to Amblyomma species antigens. Reactions to D. andersoni salivary antigens in tests of both purebred and crossbred calves with acquired resistance to A. americanum suggest that Amblyomma species salivary gland antigens might have cross reactive moieties with a salivary extract prepared from D. andersoni. Peripheral blood lymphocyte in vitro responsiveness to Amblyomma species antigens was detected in purebred calves after a first, second, and third infestation, indicating the presence of cells of the immune system capable of recognizing and undergoing blast transformation in response to tick salivary components.(ABSTRACT TRUNCATED AT 250 WORDS)
A content-based image retrieval system using extended SQL in RDBMS (2002)

We implement an efficient image retrieval system via a content-based approach in the relational database system. In our system, as the preprocessing stages, we extract the color and texture features from the input image to get the retrieval keywords in the image database. First, our system classifies the images roughly by the color features using the ART2 neural network model. The classified information is stored in a relational database with the original image. To retrieve images similar to the query image, we extend the relational SQL statement coupled with the ART2 function in the WHERE condition clause. Next, to retrieve final results of images, we compare the query image with the candidate images which have the same category information by the texture features. The proposed system is implemented on Oracle DBMS. It shows satisfactory retrieval results in a test of the sample image database.
Soliton pulse compression in photonic band-gap fibers. (2005)

We report on pulse compression using a hollow-core photonic band-gap fiber filled with Xe. Output pulses with megawatt peak powers and durations of 50 fs have been generated from 120-fs input pulses. The large third-order dispersion inherent in these fibers degrades the optimal compression ratio and prevents generation of even shorter pulses. Nevertheless, for picosecond input pulses, compression to less than 100 fs is predicted.
Can We Predict the Spreading of a Two-Liquid System from the Spreading of the Corresponding Liquid–Air Systems? (2011)

We present new data obtained from the spreading of a series of oil droplets, on top of a hydrophobic grafted silicon substrate, in air and immersed in water. We follow the contact angle and radius dynamics of hexane, dodecane, hexadecane, dibutyl phthalate, and squalane from the first milliseconds to approximately 1 s. Analysis of the images allows us to make several hundred contact angle and droplet radius measurements with great accuracy. The G-Dyna (Seveno et al. Langmuir 2010, 25, 13034) software is then used to fit the data with one of the wetting theories, the molecular-kinetic theory (MKT) (Blake et al. J. Colloid Interface Sci.1969, 30, 421), which takes into account the dissipation at the three-phase zone at the contact line. This theory allows us to extract the coefficient of friction of the contact line, which expresses the relationship between the driving force, that is, the unbalanced Young force, and the contact-line velocity V. It is first shown that the MKT is appropriate to describe the experimental data and then that the contact-line friction is a linear function of the viscosity as theoretically predicted. This is checked for oil-air and oil-water systems. A linear relation between the contact-line friction measured in oil-water systems and the contact-line frictions of the parent single liquid system seems plausible. To the best of our knowledge, this is the first trial to establish a link between the dynamics of wetting in liquid-liquid and in liquid-air systems.

Applications of rosin-modified epoxidized soya bean oil acrylate in UV cure coatings. (1992)

The cured films of epoxidized soya bean oil acrylate containing abietic group will exhibit a variety of properties by the proper choice of their components' ucture and molecular weight. In this paper, the general properties of the rosin-modified epoxidized soya bean oil acrylate, such as adhesion, cure rate, glossiness, chemical and abrasion resistance, are discussed and compared with other oligomers without abietic group.
Sensorless Current Sharing Analysis and Scheme for Multiphase Converters (2007)

Current sharing control in multiphase converters is essential for stable and safe operation under variable conditions or applications. In conventional current sharing schemes, this requires the sensing and processing on each phase current through a current sharing/balancing controller, which adds complexity, size, and cost to the converter design. In most cases, conventional schemes are usually based on achieving a pre-set current sharing ratio between phases (usually equal current value among different phases), assuming that the phase design is known (or symmetric in the case of equal sharing ratio), which may not result in the optimum efficiency. The accuracy of achieving the pre-set current sharing ratio is sensitive to the current sensing accuracy in all phases, which requires careful and tedious calibration of sensing circuitries. In this paper, theoretical analysis results are presented to derive a sensor less current sharing method. The analysis is further expanded to reveal the boundary conditions that result in not achieving the desired current sharing ratio. The presented method is described and verified with experimental results from a proof of concept prototype based on digital controller implementation.
Congenital myotonic dystrophy: respiratory function at birth determines survival. (1989)

The clinical features of 14 neonates with congenital myotonic dystrophy were retrospectively reviewed. These babies represent all the new cases of congenital myotonic dystrophy seen in this department since 1982. Twelve babies were referred because of either difficulties in diagnosis or difficulties in the management of their respiratory problems. Of the 14 babies, 13 had birth asphyxia, 11 were premature, and four had intrauterine growth retardation. Ten babies required artificial ventilation from birth. Abnormalities on chest radiography included thin ribs (n =9) and raised right hemidiaphragms (n = 5). Recurrent episodes of collapse and consolidation of the lungs secondary to poor swallowing occurred in all ventilated babies. All babies ventilated for longer than four weeks died of respiratory complications before the age of 15 months. One baby was successfully extubated after diaphragmatic plication, but he died a few months later. Duration of ventilation was the best guide to prognosis.

Comparison of HgCdTe- and LiTaO 3 -detector-based differential absorption radiometers (DARs) for remote chemical effluent detection (2003)

The need for the development of a low-cost, low-energy, portable remote sensor of hazardous chemicals for first responders and facility protection has been recognized. Differential absorption radiometry (DAR) based on uncooled detectors has been identified as a possible solution. However, uncooled detectors have lower detectivity than cooled detectors and thus require efficient light management. Two prototype DARs, one consisting of two cryogenically cooled HgCdTe detectors and the other consisting of two LiTaO<sub>3</sub> pyroelectric detectors, designed to detect methanol vapor, were built and tested in the laboratory to compare their relative performance by measuring detectivity limits under controlled conditions. With Δ<i>T</i> = 8.3 K between the methanol vapor and a radiation source having an emissivity of ε<sub>s</sub> = 0.92, methanol detection limits of 3.14x10<sup>-4</sup> atm-cm and 3.5x10<sup>-3</sup> atm-cm were projected for the HgCdTe and pyroelectric based DARs with similar optics, respectively, assuming that a minimum SNR less than or equal to 5 is required for positive detection and identification. Evaluation of the individual detectors in each DAR demonstrated that the detector limited noise equivalent temperature difference (NETD) for the HgCdTe detector was 381 μK whereas the detector limited NETD for the pyroelectric detector was 110 mK. With a 1 s exposure to the source, temperature fluctuations in the environment increased the NETD of the HgCdTe detector to 31.0 mK whereas the NETD of the pyroelectric detector was 115 mK. These results indicated that the advantage of the HgCdTe based DAR relative to the pyroelectric based DAR is much smaller than the advantage projected by their detector limited characteristics such as D*. Thus for remote sensing applications where cost is critical, the use of pyroelectric detectors can provide acceptable performance characteristics when the signal incident on the detector is increased only by x10 relative to the signal required for similar sensitivity using HgCdTe detectors.

Interactive Design of Developable Surfaces (2016)

We present a new approach to geometric modeling with developable surfaces and the design of curved-creased origami. We represent developables as splines and express the nonlinear conditions relating to developability and curved folds as quadratic equations. This allows us to utilize a constraint solver, which may be described as energy-guided projection onto the constraint manifold, and which is fast enough for interactive modeling. Further, a combined primal-dual surface representation enables us to robustly and quickly solve approximation problems.
Dielectric resonator antennas supported by ‘infinite’ and finite ground planes (1997)

Dielectric resonator antennas have received an increased attention in recent years. For the convenience of feed, they are normally used with the support of a ground plane of a finite size. We report our experimental study of the size effect of the ground plane on a cylindrical dielectric resonator antenna coupled using a probe. The parameters studied include resonance frequency, radiation pattern, gain and bandwidth and they are compared with those obtained theoretically assuming the ground plane is of infinite size. It shows that the largest effect occurs when the diameter of the ground plane is small or less than one half of a wavelength.
Invited review: Prion‐like transmission and spreading of tau pathology (2014)

Filaments made of hyperphosphorylated tau protein are encountered in a number of neurodegenerative diseases referred to as 'tauopathies'. In the most prevalent tauopathy, Alzheimer's disease, tau pathology progresses in a stereotypical manner with the first lesions appearing in the locus coeruleus and the entorhinal cortex from where they appear to spread to the hippocampus and neocortex. Propagation of tau pathology is also characteristic of argyrophilic grain disease, where the tau lesions appear to spread throughout distinct regions of the limbic system. These findings strongly implicate neurone-to-neurone propagation of tau aggregates. Isoform composition and morphology of tau filaments can differ between tauopathies suggesting the existence of conformationally diverse tau strains. Altogether, this points to prion-like mechanisms in the pathogenesis of tauopathies.
Joint TX/RX IQ Mismatch Compensation Based on a Low-IF Internal Feedback Architecture (2012)

Modern radios use in-phase (I) and quadrature-phase (Q) channels for transmission and reception. However, IQ matching for high image rejection ratio is difficult and costly to realize by pure analog circuit techniques. Therefore, digital-assisted IQ compensation is required. This paper presents a novel joint TX/RX IQ compensation (JTRC) algorithm for low-IF feedback architecture. Conventional approaches are based on time-domain processing of test tones or frequency-domain processing of pilots in orthogonal frequency-division multiplexing (OFDM) systems. In contrast, JTRC employs time-domain blind source separation (BSS) for both OFDM and non-OFDM based systems without placing a specific requirement on the type of test signal. For example, JTRC supports both tones and modulated signals. Moreover, JTRC can be performed in the background during normal transmission mode using the actual transmitted signal. Unlike other BSS approaches that can only compensate for RX IQ mismatches while assuming a matched transmitter, JTRC can jointly compensate for both TX and RX IQ mismatches. We present an in-depth analysis that validates the JTRC algorithm and show simulation results that demonstrate its effectiveness.
HF data link protocol RF simulator performance based on Stanag 4538 and Stanag 4539 (2004)

STANAG 4538 (S4538) defines a pair of ARQ protocols that provide error free data transfer between HF terminals or nodes. These protocols utilize a form of code combining to automatically adapt to the conditions of the HF channel. The achievable throughput of these data link protocols is limited by the choice of the underlying waveform. STANAG 4539 (S4539) defines a set of high data rate HF modem waveforms that provide on-air data rates up to 12,800 bps. The data link protocols developed by Harris Corporation and discussed in this paper, HDL+, apply the code combining concepts to the higher capacity data waveforms of S4539. HDL+ is currently being considered by the NATO HF radio ad hoc working group as an enhancement to S4538. The paper begins with an overview of the current definition of HDL+ highlighting several waveform level improvements that provide better throughput and lower latency than existing standard approaches, when channel conditions allow. The paper continues by presenting throughput performance measured on the AN/PRC-150C HF tactical radio using a hardware RF channel simulator setup comparing HDL+ with the data link protocol defined in S4538. The paper also presents comparison data of IP message load versus message delivered for a simple mesh network using the same RF simulator setup.

Immobilization of DNA for scanning probe microscopy. (1992)

Reproducible scanning tunneling microscope and atomic force microscope images of entire molecules of uncoated plasmid DNA chemically bound to surfaces are presented. The chemically mediated immobilization of DNA to surfaces and subsequent scanning tunneling microscope imaging of DNA molecules demonstrate that the problem of molecular instability to forces exerted by the probe tip, inherent with scanning probe microscopes, can be prevented.
Neuromuscular Monitoring : A Review (2006)

Residual neuromuscular blockade in the postoperative period contributes to significant morbidity and possibly mortality. The incidence of residual neuromuscular blockade has been shown to decrease with the use of neuromuscular monitoring and short acting neuromuscular blocking drugs. Because of marked variation in patient&apos;s sensitivity to neuromuscular blockade, the neuromuscular function of the patient receiving intermediate or long action muscle relaxant should be monitored. This article reviews the basic principles of peripheral nerve stimulation, pattern of nerve stimulation and methods used to evaluate evoked neuromuscular responses.
Subspace based estimation of the signal to interference ratio for TDMA cellular systems (2002)

The signal-to-interference ratio (SIR) has been highlighted in the literature to be a most efficient criterion for several methods aiming at reducing the effects of cochannel interference, e.g. diversity reception, dynamic channel allocation and power control. In this paper we address the problem on how to obtain fast and accurate measurements of this parameter in a practical context. We develop a general SIR estimation technique for narrow-band cellular systems, that is based on a signal subspace approach using the sample covariance matrix of the received signal. Simulation results for a GSM-like system show that the SIR can be estimated to within an error of 0.3 dB after only 200 ms, or within an error of 0.1 dB after only 0.6 seconds.
