Multilayer electroformed devices on silicon substrates (2000)

A simple, low-temperature UV electroforming process has been described which is capable of producing multi-level nickel devices on silicon substrates. The process has been used to realise two-axis electrostatic resonators, in which resonant excitation and electrothermal tuning have been demonstrated.
Reaction Mechanisms of Plasma‐ and Thermal‐Assisted Chemical Vapor Deposition of Tetraethylorthosilicate Oxide Films (1990)

Plasma‐ and thermal‐assisted chemical vapor deposited (CVD) tetraethylorthosilicate (TEOS) oxide films were deposited on silicon substrates using a single‐wafer reactor. The deposition kinetics of both plasma and thermal CVD processes were studied as a function of temperature. Film properties and bonding structure were analyzed for as‐deposited and annealed films using Fourier transform infrared spectroscopy (FTIR), Auger, x‐ray photoelectron spectroscopy (XPS), and nuclear reaction analysis (NRA) techniques. The thermal TEOS films were found to be more porous and to contain more hydrogen, but were more conformal than plasma‐deposited TEOS films. Without a plasma, thermal temperatures can assist gas‐phase reactions between ozone and TEOS (oxidation) to form conformal oxide films at as low as 200°C. With a plasma, both gas‐phase and subsequent surface CVD reactions between TEOS, ozone, and oxygen are substantially enhanced, thus result in CVD films with higher quality.
A high-performance multibit /spl Delta//spl Sigma/ CMOS ADC (2000)

The design of a multibit /spl Delta//spl Sigma/ converter is presented. It uses a third-order 4-bit /spl Delta//spl Sigma/ topology with data weighted averaging (DWA) to reduce the linearity requirements of the digital-to-analog converters in the feedback loop. The implementation of the DWA algorithm is optimized to minimize the delay introduced in the feedback loop, resulting in clock frequencies up to 100 MHz. Behavioral models are used to determine several building block specifications. An accurate model is used to analyze the combined effect of the dominant closed loop pole of the operational transconductance amplifier (OTA), the slew rate and the nonzero switch resistance. It is shown that the offset requirements for the quantizer result in a large input capacitance of the quantizer. Therefore scaling of the OTAs, as classically employed in single-bit /spl Delta//spl Sigma/ converters, can no longer be used. For an oversampling ratio of only 24, the converter achieves a signal-to-noise ratio of 95 dB, a signal-to-noise-plus-distortion ratio of 89 dB and an input dynamic range of 97 dB after comb-filtering. The converter is sampled at 60 MHz, resulting in a 2.5 MS/s output rate. It is implemented in a standard 0.65-/spl mu/m CMOS technology, occupies 5.3 mm/sup 2/ and consumes 295 mW from a 5-V power supply. When clocked at 100 MHz with an oversampling ratio of 8, a 12-bit resolution is achieved at an output rate of 12.5 MS/s.
Update on osteopathic medical concepts and the lymphatic system (1996)

The osteopathic medical profession has long recognized the importance of the lymphatic system in maintaining health. A review of scientific studies shows much information on the mechanisms and importance of lymph circulation. Many osteopathic manipulative techniques designed to treat patients with tissue congestion are based on early research recognizing that lymph flow is influenced by myofascial compression. Osteopathic manipulative treatment of the diaphragm was substantiated when pressure differentials created by the thoracic diaphragm were shown to influence lymph flow. Current research demonstrates that autonomically mediated, intrinsic lymphatic contractility plays a significant role in lymph propulsion, supporting the use of osteopathic manipulative techniques directed at influencing the autonomic nervous system to improve lymphatic circulation. Although research provides an explanation of how osteopathic manipulative techniques influence the lymphatic system, experimentation to test the direct influence of manipulation on lymph circulation is needed. Clinical outcomes studies are also necessary to substantiate the clinical efficacy of osteopathic manipulative techniques.
Multi‐turn time‐of‐flight mass spectrometers with electrostatic sectors (2003)

The mass resolution of a time-of-flight (TOF) mass spectrometer is directly proportional to its total flight pathlength. Multi-turn or multi-passage ion optical geometries are necessary to obtain fight distances of sufficient length within reasonable size limitations. We have investigated ion optics for a multi-turn TOF mass spectrometer with electrostatic sectors. The concept of 'perfect' focusing conditions is introduced. Furthermore, a new type of multi-turn TOF mass spectrometer, the MULTUM Linear plus, was developed. It consists of four cylindrical electric sectors and 28 electric quadrupole lenses. It has a vacuum chamber 60 x 70 x 20 cm in size. Mass resolution is demonstrated to increase according to the number of ion cycles. A mass resolution of 350 000 (m/z = 28, FWHM) was achieved after 501.5 cycles. The MULTUM Linear plus analyzer is not simple, however; 28 electric quadrupole lenses are used. In order to reduce the number of ion optical parts, an improved multi-turn TOF mass spectrometer, the MULTUM II, consisting of only four toroidal electric sectors, was also developed. The possibility of tandem mass spectrometric applications using multi-turn TOF mass spectrometers is also discussed.
A feedback mechanism regulates monoallelic odorant receptor expression (2004)

In olfactory neurons, expression of a single odorant receptor (OR) from a repertoire of >1000 genes is required for odor coding and axonal targeting. Here, we demonstrate a role for OR protein as an essential regulator in the establishment of monoallelic OR expression. An OR-promoter-driven reporter expresses in a receptor-like pattern but, unlike a native OR, is coexpressed with an additional OR allele. Expression of a functional OR from the identical promoter eliminates expression of other OR alleles. The presence of an untranslatable OR coding sequence in the mRNA is insufficient to exclude expression of a second OR. Together, these data identify the OR protein as a critical element in a feedback pathway that regulates OR selection.

French Caucasian Population Data for HUMTH01 and HUMFES/FPS Short Tandem Repeat (STR) Systems (1995)

Abstract The recent technology of amplification of DNA sequences by the polymerase chain reaction (PCR) has already proved to be a very useful tool for the analysis of variable number of tandem repeat (VNTR) loci. Short tandem repeat (STR) loci appear as other promising PCR-based identification systems. In fact, DNA typing based on PCR amplification of STRs is very sensitive and allows to overcome major problems encountered when using the RFLP method, such as typing of very small amounts of DNA, highly degraded DNA or mixtures of DNA from more than one individual. Two STR systems, HUMTH01 (a tetranucleotide repeat (AATG) sequence located on chromosome 11) and HUMFES/FPS (a tetranucleotide repeat (ATTT) sequence located on chromosome 15) were investigated in order to determine allele and genotype frequencies for a French caucasian population sample. HUMTH01 and HUMFES/FPS alleles were amplified by the use of PCR and amplified STR sequences were analyzed on 6% Hydrolink Long Ranger gels and visualized by silver staining. The study was conducted on a sample of unrelated individuals (N ≈ 190) randomly selected from the French caucasian population. The genotype distributions met Hardy-Weinberg expectations for both HUMTH01 and HUMFES/FPS STR systems. Furthermore, an additional allele, never reported before was observed at the HUMFES/FPS locus: it migrates as an allele containing 7 repeat units and corresponds to the smallest allele identified for this locus.
Expanding the vocabulary of a connectionist recognizer trained on the DARPA Resource Management corpus (1992)

It is shown how the compositional representation (CR) previously used for lexical access from sub-word recognizers for a relatively small word vocabulary can be extended to much larger vocabularies without further training. This is demonstrated for the DARPA Resource Management database where, using sub-word units as input, words are presented distributively over a fixed number of units and classified using a simple network. Initially, the architecture is trained on 147 words achieving an accuracy 91.2%. Then, leaving the recognizer unchanged, it is shown how additional output units can be added to the network to increase the vocabulary to the complete set of 975 phonetically distinct words. On this extended vocabulary the performance dropped to 66% but this drop is less than the expected drop due to the perplexity increase. Further improvement would be achieved by improving the performance on the original data set.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A resonant magnetic field microsensor with high quality factor at atmospheric pressure (2008)

A resonant magnetic field microsensor with a high quality factor at atmospheric pressure has been designed, fabricated and tested. This microsensor does not require vacuum packaging to operate efficiently and presents a compact and simple geometrical configuration of silicon. This geometry permits us to decrease the size of the structure and facilities its fabrication and operation. It is constructed of a seesaw plate (400 × 150 × 15 µm3), two torsional beams (60 × 40 × 15 µm3), four flexural beams (130 × 12 × 15 µm3) and a Wheatstone bridge with four p-type piezoresistors. The resonant device exploits the Lorentz force principle and operates at its first resonant frequency (136.52 kHz). A sinusoidal excitation current of 22.0 mA with a frequency of 136.52 kHz and magnetic fields from 1 to 400 G are considered. The mechanical response of the microsensor is modeled with the finite element method (FEM). The structure of the microsensor registered a maximum von Mises stress of 53.8 MPa between the flexural and the torsional beams. Additionally, a maximum deflection (372.5 nm) is obtained at the extreme end of the plate. The proposed microsensor has the maximum magnetic sensitivity of 40.3 µV G−1 (magnetic fields <70 G), theoretical root-mean square (rms) noise voltage of 57.48 nV Hz−1/2, theoretical resolution of 1.43 mG Hz−1/2 and power consumption less than 10.0 mW.
Fuzzy logic for software metric models throughout the development life-cycle (2003)

One problem faced by managers who are using project management models is the elicitation of numerical inputs. Obtaining these with any degree of confidence early in a project is not always feasible. Related to this difficulty is the risk of precisely specified outputs from models leading to overcommitment. These problems can be seen as the collective failure of software measurements to represent the inherent uncertainties in managers' knowledge of the development products, resources, and processes. It is proposed that fuzzy logic techniques can help to overcome some of these difficulties by representing the imprecision in inputs and outputs, as well as providing a more expert-knowledge based approach to model building. The use of fuzzy logic for project management however should not be the same throughout the development life cycle. Different levels of available information and desired precision suggest that it can be used differently depending on the current phase, although a single model can be used for consistency.

Characterization of High Temperature Polymer Thin Films for Power Conditioning Capacitors (2009)

Abstract : Capacitor dielectrics that can operate above 150 deg C are needed for power electronics in military propulsion and weapons systems. This report characterized and compares two high temperature polymer film capacitor candidates, poly(ether imide) (PEI) and poly(ether ether ketone) (PEEK), with poly(phenylene sulfide) (PPS) and biaxially oriented polypropylene (BOPP), which offer limited performance at high temperature. Breakdown strength at room temperature was about 320 MV/m for PEEK, 500 MV/m for PPS and PEI, and 720 MV/m for BOPP. At 150 deg C, breakdown strength for PEI decreased about 16% and about 13% for PEEK, while PPS remained unchanged. BOPP's maximum test temperature was 100 deg C, at which breakdown strength decreased by about 11%. Dielectric loss measurements suggest PPS has greater electrical conductivity at 200 deg C than PEEK or PEI, and PEI has a lower loss than PEEK at temperatures above 150 deg C and frequencies higher than 1 kHz. The low E-field conductivity for PPS was 6.90x10(-14) S/m at 165 deg C and 1.72x10(-11) S/m at 200 deg C; the manufacturer listed room temperature conductivity as 2x10(-16) S/m. The effect of conductivity on the temperature rise of the capacitors was analyzed. More measurements are needed to determine the conductivity of PEEK and PEI. Based on the measured data for breakdown strength and dielectric properties, PEI appears to be the better candidate.
Philosophy Americana: making philosophy at home in American culture (2006)

In this engaging book, Douglas Anderson begins with the assumption that philosophy—the Greek love of wisdom—is alive and well in American culture. At the same time, professional philosophy remains relatively invisible.\nAnderson traverses American life to find places in the wider culture where professional philosophy in the distinctively American tradition can strike up a conversation. How might American philosophers talk to us about our religious experience, or political engagement, or literature—or even, popular music?\nAnderson’s second aim is to find places where philosophy happens in nonprofessional guises—cultural places such as country music, rock’n roll, and Beat literature. He not only enlarges the tradition of American philosophers such as John Dewey and William James by examining lesser-known figures such as Henry Bugbee and Thomas Davidson, but finds the theme and ideas of American philosophy in some unexpected places, such as the music of Hank Williams, Tammy Wynette, and Bruce Springsteen, and the writings of Jack Kerouac.\nThe idea of “philosophy Americana” trades on the emergent genre of “music Americana,” rooted in traditional themes and styles yet engaging our present experiences. The music is “popular” but not thoroughly driven by economic considerations, and Anderson seeks out an analogous role for philosophical practice, where philosophy and popular culture are co-adventurers in the life of ideas. Philosophy Americana takes seriously Emerson’s quest for the extraordinary in the ordinary and James’s belief that popular philosophy can still be philosophy.
The PatchMatch randomized matching algorithm for image manipulation (2011)

This paper presents a new randomized algorithm for quickly finding approximate nearest neighbor matches between image patches. Our algorithm offers substantial performance improvements over the previous state of the art (20--100×), enabling its use in new interactive image editing tools, computer vision, and video applications. Previously, the cost of computing such matches for an entire image had eluded efforts to provide interactive performance. The key insight driving our algorithm is that the elements of our search domain---patches of image pixels---are correlated, and thus the search strategy takes advantage of these statistics. Our algorithm uses two principles: first, that good patch matches can be found via random sampling, and second, that natural coherence in the imagery allows us to propagate such matches quickly to surrounding areas. Our simple algorithm allows finding a single nearest neighbor match across translations only, whereas our general algorithm additionally allows matching of k -nearest neighbors, across all rotations and scales, and matching arbitrary descriptors. This one simple algorithm forms the basis for a variety of applications including image retargeting, completion, reshuffling, object detection, digital forgery detection, and video summarization.

Neutrophils Versus<i>Staphylococcus aureus</i>: A Biological Tug of War (2013)

The pathogen Staphylococcus aureus is well adapted to its human host. Neutrophil-mediated killing is a crucial defense system against S. aureus; however, the pathogen has evolved many strategies to resist killing. We first describe the discrete steps of neutrophil activation and migration to the site of infection and the killing of microbes by neutrophils in general. We then highlight the different approaches utilized by S. aureus to resist the different steps of neutrophil attack. Various molecules are discussed in their evolutionary context. Most of the molecules secreted by S. aureus to combat neutrophil attacks at the site of infection show clear human specificity. Many elements of human neutrophil defenses appear redundant, and so the evasion strategies of staphylococci display redundant functions as well. All efforts by S. aureus to resist neutrophil-mediated killing stress the importance of these mechanisms in the pathophysiology of staphylococcal diseases. However, the highly human-specific nature of most host-pathogen interactions hinders the in vivo establishment of their contribution to staphylococcal pathophysiology.
Image Retrieval Using Textual Cues (2013)

We present an approach for the text-to-image retrieval problem based on textual content present in images. Given the recent developments in understanding text in images, an appealing approach to address this problem is to localize and recognize the text, and then query the database, as in a text retrieval problem. We show that such an approach, despite being based on state-of-the-art methods, is insufficient, and propose a method, where we do not rely on an exact localization and recognition pipeline. We take a query-driven search approach, where we find approximate locations of characters in the text query, and then impose spatial constraints to generate a ranked list of images in the database. The retrieval performance is evaluated on public scene text datasets as well as three large datasets, namely IIIT scene text retrieval, Sports-10K and TV series-1M, we introduce.
Robust <i>H</i><sub>∞</sub> glucose control in diabetes using a physiological model (2000)

Abstract A robust H ∞ controller was developed to deliver insulin via a mechanical pump in Type I diabetic patients. A fundamental nonlinear diabetic patient model was linearized and then reduced to a third‐order linear form for controller synthesis. Uncertainty in the nonlinear model was characterized by up to ±40% variation in eight physiological parameters. A sensitivity analysis identified the three‐parameter set having the most significant effect on glucose and insulin dynamics over the frequency range of interest ω = [0.002, 0.2] (rad/min). This uncertainty was represented in the frequency domain and incorporated in the controller design. Controller performance was assessed in terms of its ability to track a normoglycemic set point (81.1 mg/dL) in response to a 50 g meal disturbance. In the nominal continuous‐time case, the controller maintained glucose concentrations within ±3.3 mg/dL of set point. A controller tuned to accommodate uncertainty yielded a maximum deviation of 17.6 mg/dL for the worst‐case parameter variation.
Grounding architectures for enabling ground fault ride-through capability in DC microgrids (2017)

Distributed generation in the power grid will result in considerable efficiency improvement and increase in reliability and stability of the grid. And DC microgrids have clear benefits such as higher reliability, higher efficiency, better compatibility with DC loads, expandability and etc., over their AC equivalent systems. Although DC microgrids have clear advantages over the AC microgrids, but there is not sufficient information available on their grounding. Realizing the grounding of DC systems would accelerate employing of these systems in the power grid. Grounding is a complex topic involving many design considerations and trade-offs and it is needed to ensure the safety of personnel and equipment as well as detection of ground fault in the system. Grounding of DC power system should be designed to 1) minimize the leakage current during normal operation, 2) maximize the safety of personnel and equipment under fault conditions. This work examines the different grounding methods and system architectures and discusses the design trade-offs in terms of safety, reliability, detection, mitigation, noise, and cost. We examine impedance grounding, isolation, and bi-polar architectures and discuss their benefits with respect to these criteria.
The implementation of modal filters for control of structures (1985)

The most common technique for the control of structures is modal control. In modal control, the differential equations in terms of actual coordinates are replaced by a set of ordinary differential equations in terms of the modal coordinates known as modal equations. In designing feedback controls in conjunction with the modal equations, one must know the modal states for the modes targeted for control. The sensors measure actual states, however. The modal states can be estimated by means of a Luenberger observer or modal filters. The modal filters produce estimates of the modal states from distributed measurements of the states. If distributed measurements are not available, then they can be reconstructed from measurements at discrete points via interpolation. This paper examines various questions associated with the implementation of modal filters, such as the effect of choice of interpolation functions and sensors locations, as well as of measurement errors, on the state estimation process. The method is demonstrated by means of two numerical examples.
