The design of an on-chip RC-based oscillator, implemented in a standard 0.35 μm CMOS process, without any external component, is presented. The proposed oscillator provides a clock signal at a frequency of about 80 KHz with a temperature coefficient smaller than 842 ppm/°C over a temperature range from 0 to 80°C and a standard deviation due to process variations smaller than 4%, without any external trimming. The proposed oscillator operates with a supply voltage of 1 V and has a power consumption of about 1 μW at room temperature. The chip area is 0.24 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> .
Performance improvement methods for DECT and other non-coherent GMSK systems (2003)

A simple and low cost configuration, fourth-order premodulation Gaussian LPF (GLPF) paired with fourth-order postdiscriminator Butterworth LPF (BLPF), is demonstrated to yield robust performance in GMSK systems. Frequency drift of voltage-controlled oscillator (VCO) and IC-type mismatch will cause DC-offset during noncoherent demodulation. A DC-offset compensation technique based on the decision detection concept is investigated. By using this method, 40% and 80% of DC-offset is compensated within 0.5 dB of BER performance degradation. The use of a pseudo error monitor for DC-offset compensation is also proposed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

A Third System of the Arts? An Exploration of Some Ideas from Larry Shiner's The Invention of Art: A Cultural History (2008)

I explore some implications of Larry Shiner’s view that fine art is a modern invention. In part I, I briefly summarize Shiner’s main thesis and defend it against some misunderstandings and objections that have appeared in the literature. In part II, I discuss Shiner’s remarks about the possible emergence of what he calls a “third system of the arts.” I ask what such a system might look like, consider some signs that it may indeed be emerging, and venture a suggestion about what would be required for it actually to come about.
High‐Temperature Behavior of Chemically Treated Silicon Nitride Powders (1988)

The mechanical properties of chemically treated, then sintered, Si 3 N 4 was studied. Raw materials consisted of two types of Si 3 N 4 produced by the nitridation of silicon. The chemical treatment involved leaching in different acids (HCl, HNO 3 , HF, and combinations thereof). The powders were sintered by hot isostatic pressing with 2.5% yttria, and the high‐temperature properties of the resultant materials were evaluated by the stepped‐temperature stress rupture (STSR) method (24‐h hold time at 150‐MPa stress at 1000°, 1100°, 1200°, 1300°, and 1400°C). A significant decrease in high‐temperature performance was observed for acidleached powders, especially when HF‐containing acids were used.
Patient Expectancy as a Mediator of Placebo Effects in Antidepressant Clinical Trials (2016)

Patient expectancy is a significant mediator of placebo effects in antidepressant trials. Expectancy-related interventions should be investigated as a means of controlling placebo responses in antidepressant clinical trials and improving patient outcome in clinical treatment.
THF EARLY STAGES OF ABSORPTION OF INJECTED HORSERADISH PEROXIDASE IN THE PROXIMAL TUBULES OF MOUSE KIDNEY: ULTRASTRUCTURAL CYTOCHEMISTRY BY A NEW TECHNIQUE (1966)

The early stages of absorption of intravenously injected horseradish peroxidase in proximal tubules of mouse kidney were studied with a new ultrastructural cytochemical technique. In animals killed as early as 90 sec after injection, reaction product was found on the brushborder membranes and in the apical tubular invaginations. From the latter structures it was transported to the apical vacuoles, in which it was progressively concentrated to form protein absorption droplets. The method, which employs 3,3'-diaminobenzidine as oxidizable substrate, gives sharp localization and is sensitive. This system is advantageous in studying the early stages of renal tubular protein absorption, since small amounts of protein on membranes and in tubules and vesicles can be detected easily. The method also appears promising for studying protein transport in a variety of other cells and tissues.
SILICATE FOAM FOR AIRDROP CUSHIONING (1968)

Abstract : Sodium silicate foam was proposed as a possible substitute for paper honeycomb as an airdrop cushion. Experimental efforts to implement silicate foam panels using a 2 kilowatt microwave energy source proved inadequate. Larger energy input with a more uniform flux appeared to be necessary to accommodate the size of panels desired. A sodium silicate/perlite aggregate formulation was found to fulfill most of the product specifications. Areas for improvement include collapsed to expanded ratio, maximum strain level, rectangularity of stress-strain curve, product density and friability. The silicate/perlite formulation and foamed sodium silicate formulations allow a wide latitude of variation and control. It is believed that optimization of formulation and heating equipment can be realized. (Author)
Recent Developments in Tandem White Organic Light-Emitting Diodes (2019)

Tandem white organic light-emitting diodes (WOLEDs) are promising for the lighting and displays field since their current efficiency, external quantum efficiency and lifetime can be strikingly enhanced compared with single-unit devices. In this invited review, we have firstly described fundamental concepts of tandem device architectures and their use in WOLEDs. Then, we have summarized the state-of-the-art strategies to achieve high-performance tandem WOLEDs in recent years. Specifically, we have highlighted the developments in the four types of tandem WOLEDs (i.e., tandem fluorescent WOLEDs, tandem phosphorescent WOLEDs, tandem thermally activated delayed fluorescent WOLEDs, and tandem hybrid WOLEDs). Furthermore, we have introduced doping-free tandem WOLEDs. In the end, we have given an outlook for the future development of tandem WOLEDs.
A Randomized Trial of Maintenance Therapy for Vasculitis Associated with Antineutrophil Cytoplasmic Autoantibodies (2003)

In patients with generalized vasculitis, the withdrawal of cyclophosphamide and the substitution of azathioprine after remission did not increase the rate of relapse. Thus, the duration of exposure to cyclophosphamide may be safely reduced.
Physiological effects of soybean seed lipoxygenases on insects. (1990)

Defense against insect attack was investigated for the lipid oxidation products made by soybean seed lipoxygenases, to study the physiological role of the enzymes in seeds. The repellent effect against bean bugs (Riptortus clavatus Thunberg), a major soybean pest, was observed in products of linoleic acid oxidation by lipoxygenases such as linoleic acid monohydroperoxides and hexanal. Bean bugs preferred lipoxygenase isozyme (L-l, L-2, and L-3)-null seeds, especially L-2 null seeds, more than normal soybean seeds, although no significant difference was observed in feeding preference at the repening period. The lipid peroxidation products of lipoxygenases, such as linoleic acid hydroperoxide and hexanal, also repelled two species of leaf beetles that do not usually feed on soybean seeds, and the threshold value for the oligophagous strawberry leaf beetles (Galerucella vittaticollis Baly) was lower than that for the polyphagous false melon beetles (Atrachya menetriesi Falderman). These results suggested that the lipid oxidation products repelled the tested insects and that the soybean seed lipoxygenases could act defensively, although the effects of the products on the soybean pest insects was not great.
Rational Design of Cavitand Receptors for Mass Sensors (2003)

This Communication describes a rational approach to the fabrication of selective mass sensors, using multiple hydrogen-bonding type interactions encoded in a single cavitand receptor. The introduction of two inward facing hydrogen bond acceptor PO groups at the upper rim of a cavitand renders the corresponding receptor layer deposited on a mass transducer highly selective toward alcohol vapors. The molecular origin of the increased selectivity has been identified in the presence of two energetically and geometrically equivalent interaction modes available to the guest, giving to the corresponding complexes an entropic advantage over their mono PO analogues.
Volatile compounds in pine stands suffering from pine wilt disease: qualitative and quantitative evaluation (2006)

Abstract Pine wilt disease causes ecological and economic damage in Japanese pine forests in spite of intensive effort to protect them from the pine wood nematode, Bursaphelenchus xylophilus. Pine trees infected with B. xylophilus emit a characteristic bouquet of volatile compounds bioactive to the vector beetle of the nematode, Monochamus alternatus, and potentially affecting symptom development inside the trees. To investigate the qualitative and quantitative properties of volatile compounds in the field, we profiled the volatile emissions in two Japanese black pine stands, one naturally suffering from pine wilt disease and the other artificially inoculated with B. xylophilus. In both pine stands, the emission of some terpenoids from the infected trees such as (−)-α-pinene, began to increase in summer, overlapping the oviposition season of the vector beetle, but peaked in the summer and autumn. These data suggest that the beetles may not necessarily depend on the tremendous quantity of volatiles alone when they search for suitable trees on which to oviposit.
Carbon monoxide in blood: an improved microliter blood-sample collection system, with rapid analysis by gas chromatography. (1984)

We examined the sensitive assay for carboxyhemoglobin based on reaction with K3Fe(CN)6 and gas chromatography of the liberated CO. Our improvements included increased baseline stability, shorter analysis time, and simpler standardization. EDTA-containing Vacutainer Tubes (lavender-stoppered) increase the carboxyhemoglobin content of blood stored in them. The carboxyhemoglobin content of blood stored in capillary tubes containing solid heparin and saponin remained stable for two weeks. Using our improved procedures, we measured the carboxyhemoglobin content of blood from adults and neonates collected via venipuncture or heel or fingersticks. We observed no significant difference in carboxyhemoglobin content of blood obtained by venipuncture or heel stick for premature infants, 0.19 +/- 0.04 vs 0.18 +/- 0.03 mL of CO per 100 mL of blood, respectively (mean +/- SD). Nonsmoking adults (n = 19) had CO values (mean +/- SD) of 0.19 +/- 0.03 and 0.17 +/- 0.04 mL per 100 mL of blood, and smoking adults (n = 7) gave CO values of 0.96 +/- 0.49 and 0.91 +/- 0.49 mL/dL, for venipuncture and fingerstick, respectively.
Observed and forecast flood-inundation mapping application-A pilot study of an eleven-mile reach of the White River, Indianapolis, Indiana (2011)

Near-real-time and forecast flood-inundation mapping products resulted from a pilot study for an 11-mile reach of the White River in Indianapolis. The study was done by the U.S. Geological Survey (USGS), Indiana Silver Jackets hazard mitigation taskforce members, the National Weather Service (NWS), the Polis Center, and Indiana University, in cooperation with the City of Indianapolis, the Indianapolis Museum of Art, the Indiana Department of Homeland Security, and the Indiana Department of Natural Resources, Division of Water. The pilot project showed that it is technically feasible to create a flood-inundation map library by means of a two-dimensional hydraulic model, use a map from the library to quickly complete a moderately detailed local flood-loss estimate, and automatically run the hydraulic model during a flood event to provide the maps and flood-damage information through a Web graphical user interface. A library of static digital flood-inundation maps was created by means of a calibrated two-dimensional hydraulic model. Estimated water-surface elevations were developed for a range of river stages referenced to a USGS streamgage and NWS flood forecast point colocated within the study reach. These maps were made available through the Internet in several formats, including geographic information system, Keyhole Markup Language, and Portable Document Format. A flood-loss estimate was completed for part of the study reach by using one of the flood-inundation maps from the static library. The Federal Emergency Management Agency natural disaster-loss estimation program HAZUS-MH, in conjunction with local building information, was used to complete a level 2 analysis of flood-loss estimation. A Service-Oriented Architecture-based dynamic flood-inundation application was developed and was designed to start automatically during a flood, obtain near real-time and forecast data (from the colocated USGS streamgage and NWS flood forecast point within the study reach), run the two-dimensional hydraulic model, and produce flood-inundation maps. The application used local building data and depth-damage curves to estimate flood losses based on the maps, and it served inundation maps and flood-loss estimates through a Web-based graphical user interface.
Bound-Polaron Hopping in NiO (1972)

We report observation of bound-polaron hopping in pure NiO single crystals. The observed activation energy is $\ensuremath{\approx}0.7$ eV, the bandwidth $J\ensuremath{\approx}{10}^{\ensuremath{-}2}$ eV, and the binding center is suggested to be the ${\mathrm{Ni}}^{+2}$ vacancy.
Joint Image Registration and Segmentation (2006)

Image segmentation is ubiqitous in computer vision and image processing. In some applications such as in medical imaging, the problem may be very complex due to lack of sufficient image contrast, signal to noise ratio, volume avaraging, inhomogenities caused due to nonuniform magnetic field — in the case of MRI data sets, and sometimes lack of any real boundary due to the desired shape blending into the surrounding tissue. Such scenarios pose a formidable segmentation problem and provide motivation for incoporation of prior information in to the segmentation algorithms. There are several ways to incorporate priors into the segmentation formulation and we choose to use an atlas-based segmentation technique which requires that the given atlas shape/image be registered with the target image in order to find the desired shape segmentation in the target image thus requiring simultaneous registration and segmentation to be achieved. This is a natural choice for medical applications pertinent to some of the aforementioned scenarios. In this chapter, two approaches are presented, one is a pure PDE-based formulation and the other is a vriational formulation involving a level-set representation of the shape being segmented. The former approach copes with 3D non-rigid motion and the later although easily applicable to the non-rigid motion case is shown here only for the 2D rigid motion case. Efficient numerical methods are used in both the approaches and the performance of the algorithms is depicted via examples on synthetic and real 3D and 2D image data.
An Automated System for Plant-Level Disease Rating in Real Fields (2014)

Cercospora leaf spot (CLS) is the most serious disease in sugar beet plants that significantly reduces the sugar yield throughout the world. Therefore the current focus of the researchers in agricultural domain is to find sugar beet cultivars that are highly resistant to CLS. To measure their resistance, CLS is manually observed and rated in a large variety of sugar beet by different human experts over a period of a few months. Unfortunately, this procedure is laborious and subjective. Therefore, we propose a novel computer vision system, CLS Rater, to automatically and accurately rate CLS of plant images in the real field to the "USDA scale" of 0 to 10. Given a set of plant images captured by a tractor-mounted camera, CLS Rater extracts multi-scale super pixels, where in each scale a novel histogram of importances feature representation is proposed to encode both the within-super pixel local and across-super pixel global appearance variations. These features at different super pixel scales are then fused for learning a bagging M5P regress or that estimates the rating for each plant image. We test our system on the field data collected over a period of two months under different day lighting and weather conditions. Experimental results show CLS Rater to be highly consistent with a rating error of 0.65, which demonstrates higher consistency than the rating standard deviation of 1.31 by the human experts.

Behavior of Fiber Reinforced Plastic Materials in Chemical Service (1969)

A study is made of the factors leading to the degradation in mechanical properties of glass reinforced polyester exposed to aggressive chemical environments such as H2SO4, HCl, and salt solutions at elevated temperatures. The penetration of water molecules, cations, and anions into the structure is described in terms of permeation rates as a function of time, temperature, pressure, glass content, resin type, and concentration of solutions. The permeation measurements are related to the diffusivity and solubility of the penetrating species in the structure and to the resultant degradation of mechanical properties.
A Study of System Losses in a Transistorized Inverter-Induction Motor Drive System (1985)

A study is described of the system losses in a transistorized pulsewidth modulated (PWM) inverter and induction motor in a traction drive system and the development of a strategy for minimizing them. The losses include inverter losses, conventional fundamental frequency motor losses, and motor harmonic losses. The losses in both PWM and six-step square wave (SSSW) inverter operation are studied. The loss models are introduced into a motor performance analysis program allowing the computation of the drive system performance over the entire speedtorque range. The study shows that a strategy for minimizing drive system losses is a function of torque. The air gap flux density should be held at its maximum level until the torque requirement is reduced to a low value, and then the air gap flux level is reduced.

Tumor necrosis factor (TNF)-alpha directly inhibits human erythropoiesis in vitro: role of p55 and p75 TNF receptors (1995)

Two tumor necrosis factor receptors (TNFRs) with molecular weights of 55 kD (TNFR-p55) and 75 kD (TNFR-p75) have recently been identified and cloned. In previous studies, TNFR-p55 has been shown to exclusively mediate bidirectional effects of TNF-alpha on committed bone marrow granulocyte-macrophage progenitor cells, whereas both TNFR-p55 and TNFR-p75 can mediate inhibition of primitive progenitors requiring multiple cytokines to proliferate. We show here that TNF-alpha potently and directly inhibits the in vitro growth of committed erythroid progenitor cells in response to multiple cytokine combinations, and that TNF-alpha-induced inhibition of burst-forming unit-erythroid colony formation is mainly mediated through TNFR-p55, although TNFR-p75-mediated inhibition could be observed on progenitors responsive to erythropoietin alone. Moreover, at low TNF-alpha concentrations (2 ng/mL), TNF-alpha stimulates interleukin-3-dependent in vitro growth of committed granulocyte-macrophage progenitor cells, whereas it potently inhibits erythroid progenitor cell proliferation, showing that one concentration of TNF-alpha can simultaneously and bidirectionally modulate interleukin-3-dependent growth of committed granulocyte-macrophage (stimulation) and erythroid progenitor cells (inhibition).
Two novel synchronized bus-clamping PWM strategies based on space vector approach for high power drives (2002)

Two synchronized bus-clamping pulse width modulation (PWM) strategies based on the space vector approach are proposed for high-power induction motor drives. The two strategies together can produce PWM waveforms with any odd pulse number, preserving the waveform symmetries. The proposed strategies operate upto the six-step mode, maintaining the proportionality between the reference magnitude and the fundamental voltage generated throughout. These two strategies lead to lesser harmonic distortion as well as lesser peak current over the conventional space vector strategy (CSVS) in the high speed ranges of constant V/F drives. The reduction in the harmonic distortion over CSVS subject to a given maximum switching frequency (F/sub SW(MAX)/) of the inverter is demonstrated theoretically as well as experimentally for F/sub SW(MAX)/=750 Hz and 450 Hz, both with and without overmodulation. The best reduction in the distortion is as high as 30% to 50% in the different cases considered. Further, these two PWM strategies are also useful in reducing the switching frequency of the inverter over sine-triangle PWM and CSVS subject to an upper limit on the harmonic distortion.
QTL Mapping of Resistance to<i>Thrips palmi</i>Karny in Common Bean (2005)

Host plant resistance in common bean (Phaseolus vulgaris L.) is a promising component in an integrated cropping system for managing thrips (Thrips palmi Karny) infestation. This study was conducted to identify quantitative trait loci (QTLs) for resistance to thrips in common bean, using F5:7 recombinant inbred lines (RILs) as a mapping population. The RILs, derived by single seed descent (SSD) of the cross of two Mesoamerican bean lines, BAT 881 and G 21212, were found to show transgressive segregation for thrips resistance in the field. Correlations between damage and reproductive adaptation (RA) scores were significant within and between seasons. The QTLs for both traits were located based on single interval mapping (IM) and joint interval mapping (JIM) analysis using a genetic map constructed with microsatellite and random amplified polymorphic DNA (RAPD) markers. Eight of eleven resulting linkage groups (LGs) were shown to be homologous to chromosomes of the integrated linkage map of common bean. A major QTL for thrips resistance located on LG b06 explained up to 26.8% of variance for resistance in a single season and was named Tpr6.1. The JIM across several seasons revealed various QTLs on LGs b02, b03, b06, and b08, some of which were located at regions of genes encoding for disease resistance. The identification and mapping of thrips-resistance genes is expected to facilitate the development of resistant bean cultivars by using molecular marker-assisted selection.
