Interpreting statistical process control (SPC) charts using machine learning and expert system techniques (2003)

Statistical process control (SPC) charts are one of several tools used in quality control. The SPC quality control tool has been under-utilized due to the lack of experienced personnel able to identify and interpret patterns within the control charts. The Special Projects Office of the Center for Supportability and Technology Insertion (CSTI) has developed a hybrid machine-learning and expert-system software tool which automates the process of constructing and interpreting control charts. The software tool draws control charts, identifies various chart patterns, advises what each pattern means, and suggests possible corrective actions. The application is easily modifiable for process specific applications through simple modifications to the knowledge base portion using any word processing software. The authors discuss control charts, software functionality, software design, machine learning, and the expert system.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Optimal Spectral Feature Detection for Spectrum Sensing at Very Low SNR (2010)

Spectrum sensing is one of the enabling functionalities for cognitive radio systems to operate in the spectrum white space. To protect the primary incumbent users from interference, the cognitive radio is required to detect incumbent signals at very low signal-to-noise ratio (SNR). In this paper, we study a spectrum sensing technique based on spectral correlation for detection of television (TV) broadcasting signals. The basic strategy is to correlate the periodogram of the received signal with the a priori known spectral features of the primary signal. We show that this sensing technique is asymptotically equivalent to the likelihood ratio test (LRT) at very low SNR, but with less computational complexity. That is, the spectral correlation-based detector is asymptotically optimal according to the Neyman-Pearson criterion. From the system design perspective, we analyze the effect of the spectral features on the spectrum sensing performance. Through the optimization analysis, we obtain useful insights on how to choose effective spectral features to achieve reliable sensing. Simulation results show that the proposed sensing technique can reliably detect analog and digital TV signals at SNR levels as low as -20 dB.
Big Data for Health (2015)

This paper provides an overview of recent developments in big data in the context of biomedical and health informatics. It outlines the key characteristics of big data and how medical and health informatics, translational bioinformatics, sensor informatics, and imaging informatics will benefit from an integrated approach of piecing together different aspects of personalized information from a diverse range of data sources, both structured and unstructured, covering genomics, proteomics, metabolomics, as well as imaging, clinical diagnosis, and long-term continuous physiological sensing of an individual. It is expected that recent advances in big data will expand our knowledge for testing new hypotheses about disease management from diagnosis to prevention to personalized treatment. The rise of big data, however, also raises challenges in terms of privacy, security, data ownership, data stewardship, and governance. This paper discusses some of the existing activities and future opportunities related to big data for health, outlining some of the key underlying issues that need to be tackled.
<title>Substrate designs and contacts for organic light-emitting displays</title> (1998)

In the past several years, many research groups have been working on the engineering of organic light-emitting devices (OLEDs) into emissive displays. One of the major manufacturing challenges is that vacuum-deposited, low- molecular-weight organic materials are not very resistant to thermal and chemical processing, and it is therefore problematic to pattern them using standard masking and etching techniques. This has resulted in a substantial amount of the display design being manufactured into the substrate prior to the substrate being coated with the multilayer film of organic materials. In this paper an analysis of the various anode-on-substrate configurations which may be employed for OLED displays will be described and several high-work-function anodes as substitutes for the standard OLED anode of indium-tin oxide discussed.
Increased expression of Dsg2 in malignant skin carcinomas (2009)

Desmoglein 2 (Dsg2), a transmembrane cadherin of the desmosomal cell-cell adhesion structure, is downregulated with epithelial differentiation. We recently demonstrated that overexpression of Dsg2 in epidermal keratinocytes deregulates multiple signaling pathways associated with increased growth rate, anchorage-independent cell survival, and the development of skin tumors. While changes in Dsg2 expression have been observed in neoplastic lesions, the correlation of expression levels and localization of Dsg2 and the state of tumor development has not been fully established. Here we generated a highly sensitive Dsg2 antibody (Ab10) and characterized that antibody along with a previously developed Dsg2 specific antibody 10D2. Using these antibodies in immunostaining of tissue microarrays, we show a dramatic upregulation of Dsg2 expression in certain human epithelial malignancies including basal cell carcinomas (BCC; n = 12), squamous cell carcinomas (SCC; n = 57), carcinomas of sebaceous and sweat glands (n = 12), and adenocarcinomas (n = 3). Dsg2 expression was completely absent in malignant fibrosarcomas (n = 16) and melanomas (n = 15). While Dsg2 expression was consistently strong in BCC, it varied in SCC with a minor correlation between a decrease of Dsg2 expression and tumor differentiation. In summary, we have identified Dsg2 as a potential novel marker for epithelial-derived malignancies.
General Theory and Principles of External Fixation (1989)

Starting with a review of the capabilities and main complications of external fixators, this paper shows how advances made during the past two decades have rendered the method safe, reliable, and predictable. Improved component designs, new techniques of pin care, the discovery of three basic concepts that govern the safe and effective application of pin and ring fixators, and the recognition that preoperative and long-term planning are crucial to the success of the method have made external fixation the most adaptable, versatile, and gentle method for stabilizing complex injuries of soft tissue and bone.
Chemical Sniffing Instrumentation for Security Applications (2016)

Border control for homeland security faces major challenges worldwide due to chemical threats from national and/or international terrorism as well as organized crime. A wide range of technologies and systems with threat detection and monitoring capabilities has emerged to identify the chemical footprint associated with these illegal activities. This review paper investigates artificial sniffing technologies used as chemical sensors for point-of-use chemical analysis, especially during border security applications. This article presents an overview of (a) the existing available technologies reported in the scientific literature for threat screening, (b) commercially available, portable (hand-held and stand-off) chemical detection systems, and (c) their underlying functional and operational principles. Emphasis is given to technologies that have been developed for in-field security operations, but laboratory developed techniques are also summarized as emerging technologies. The chemical analytes of interest in this review are (a) volatile organic compounds (VOCs) associated with security applications (e.g., illegal, hazardous, and terrorist events), (b) chemical "signatures" associated with human presence, and
L'outburst di EX Lupi, 2008-2009 (2010)

A photometric V & B study of EX lupi was performed with the Skylive remote telescope placed at Grove Creek, Australia. The star showed a huge activity, at short and long scales, in the first 8 months after the outburst of January 2008. During 2009 the activity declined together which a large reddening of the star. The decrease of luminosity of the star was correlated statistically with the changes of the BV index (p<0.01).
Xibornol: multiple dose pharmacokinetics and diffusion in lung, tonsillar tissue and laryngeal mucosa. (1988)

In ten patients with severe chronic bronchitis and in a further 23 with planned resection of lung, tonsils or larynx, 500 mg doses, single or multiple, of xibornol (6-isobronyl-3, 4-xylenol) were administered for an antibacterial effect. The pharmacokinetics and diffusion of the drug in the tissues were studied. A high diffusion and distribution value of xibornol was observed, with levels in the tissues constantly higher than that in the serum. The concentrations reached within the respiratory tract were adequate for their antibacterial effect.
Accuracy of estimating intra-abdominal fat in obese women (2003)

ACCURACY OF ESTIMATING INTRA-ABDOMINAL FAT IN OBESE WOMEN. Stephen D. Ball, Pamela D. Swan. JEPonline. 2003;6(4):1-7. Intra-abdominal fatness (IAF) has been linked to a cluster of risk factors for cardiovascular disease. An accurate assessment of IAF is therefore critical for clinicians when assessing disease risk. The aim of this investigation was to examine the accuracy of a previously developed equation by Treuth, Hunter, and Kekes-Szabo (1) using dual-energy absorptiometry (DXA) combined with anthropometry for predicting IAF in obese women. Thirty-five peri- and post-menopausal obese women (age: 47.0 yr±7.0; BMI: 32.2±6.3 kg/m 2 ; and percent fat: 43.5±6.7 %) underwent a single-slice computed tomography (CT) scan at the level of L4-L5. In addition, a total body DXA scan and anthropometric measures including waist circumference and supine sagittal diameter measures at the level of the umbilicus, were also made. DXA-IAF was predicted using the equation: -208.2 + 4.62(SD) + 0.75(A) + 1.73(W) + 0.78(DXA). (SD=anthropometric sagittal diameter, cm; A=age, yrs; W=waist circ., cm; DXA=DXA trunk fat, %). DXA-IAF was significantly correlated with CT-IAF (r=0.628, P<0.001, SEE=53.0 cm 2 ). However, DXA-IAF values (172.2±46.9 cm 2 ) significantly overestimated CT-IAF (114.0±67.1 cm 2 ) in this population. The results from the current study indicate that the Treuth et al. equation was not able to adequately estimate IAF in obese women. Although this equation was originally generated on a wide selection of women, a limited number of the original cohort were obese. In summary, this equation may be more generalizable for normal weight women than for obese women.
Effects of observer metamerism in the determination of human color‐matching functions (1995)

Abstract This article addresses the results of the recent North and Fairchild article on observer metamerism. It reports on the results of a different experiment that produced similar results to those of North and Fairchild. The history of observer metamerism is outlined briefly and some possible sources of the large variations in inter‐observer matches are suggested. Finally, a plea for a commercially viable special index of metamerism for change in observer is formulated. © 1995 John Wiley & Sons, Inc.
New concatenated sequences for wireless indoor asynchronous DS-CDMA communications (2002)

The performance of an indoor asynchronous DS-CDMA system was investigated. The analysis focuses on spreading sequences. In particular, we compare some known sequences, characterised by particular correlation properties, with other sequences constructed by using a concatenation technique. The concatenation effect is to make the statistics of the values of the even and the odd correlation functions similar and converging towards low values, thus keeping low the multi-user interference and obtaining good BER performance.
Avoidance of patent anterior grafts at revisional coronary artery surgery: use of a lateral thoracotomy approach. (1986)

The use of a right or left lateral thoracotomy is described as an alternative approach to revisional coronary artery surgery for patients with patent anterior grafts. Five patients underwent successful revisional coronary artery grafting with a total of three internal mammary artery grafts and three saphenous vein grafts. This is a safe technique in patients for whom repeat median sternotomy is potentially hazardous, notably those with patent anterior grafts or close apposition of the heart to the sternal table.
Novel 980-nm and 490-nm light sources using vertical-cavity lasers with extended coupled cavities (2003)

We have developed novel electrically pumped, surface-emitting lasers emitting at 980 nm with an extended coupled cavity. The concept is scalable from monolithic low power (~10 mW) devices all the way to high power extended cavity lasers. The latter have demonstrated ~1 W cw multi-mode and 0.5 W cw in a TEM00 mode and a single frequency, with 90% coupling efficiency into a single-mode fiber. By inserting a nonlinear optical medium in the external cavity, efficient and compact frequency doubling has been achieved with CW output powers 5-40 mW demonstrated at 490 nm. The latter devices are especially noteworthy due to their very low noise (0.05% rms from dc-2 MHz), sub 10 mrad beam pointing stability combined with small size, low power consumption (<10 W) and high efficiency.
Development of GaN-Based Micro Chemical Sensor Nodes (2006)

Sensors based on III-N technology are gaining significant interest due to their potential for monolithic integration of RF transceivers and light sources and the capability of high temperature operations. We are developing a GaN-based micro chemical sensor node for remote detection of chemical toxins, and present electrical responses of AlGaN/GaN HEMT (high electron mobility transistor) sensors to chemical toxins as well as other common gases. Upon exposure to a chemical toxin, the sensor showed immediate increase in source-drain current (Ids). The electrical response of the sensor was clear, reproducible and characteristic of the concentration of the analyte. This is the first time that electrical responses of chemical toxins are measured with a GaN-based microsensor. Detailed analysis on response time, sensitivity and temperature dependence will be discussed.

Composition‐properties relationships in propene‐ethene random copolymers obtained with high‐yield Ziegler‐Natta supported catalysts (1986)

Abstract The crystallization and thermal behaviour of crystallizable random propene/ethene copolymers (P‐ co ‐E) was systematically investigated. Index of crystallinity and, index of γ‐form, enthalpy and entropy of fusion, equilibrium melting temperature, spherulite growth rate, and overall kinetic rate constant were determined and correlated with the overall ethene content and with the concentration of specific chemical defects as determined by 13 C NMR analysis (PEP, EPP, EPE triads). The samples of the copolymers, obtained with very‐high‐yield Ziegler‐Natta catalysts, were characterized by IR, 13 C NMR, wide angle X‐ray scattering, and differential scanning calorimetry.
Autoregulation of Actin Synthesis in Hepatocytes by Transcriptional and Posttranscriptional Mechanisms (1995)

Treatment of rat hepatocytes with the filamentous-actin-stabilizing toxin phalloidin decreased the amount of globular actin by 77% in the cytosol and by 80% in the nucleus within 12 h. Simultaneously, actin mRNA was specifically increased by 230%. The de-novo synthesis of actin mRNA, as measured by nuclear run-on transcription, was enhanced by 250%. Treatment of cells with actinomycin D blocked the increase of actin mRNA. The apparent half-life of actin mRNA was not significantly altered during treatment with phalloidin. In contrast, the globular-actin-stabilizing botulinum C2 toxin increased the amount of cytosolic globular actin by 50% within 12 h. Simultaneously, the actin mRNA level was decreased by 62%. However, de-novo synthesis of actin mRNA was not impaired. The apparent half-life of actin mRNA was decreased by approximately 60% during treatment with C2 toxin. The data strongly suggest an autoregulatory control of actin synthesis on the basis of the globular/filamentous actin ratio in rat hepatocytes at the transcriptional as well as at the posttranscriptional levels.
Silicon monolithic millimeter wave integrated oscillators (1988)

Despite considerable research effort on three terminal devices, there is currently no possibility of replacing IMPATT diodes if powerful oscillator operation in the MM-wave range is required. The development of monolithically integrated silicon IMPATT oscillators is a logical development if the difficulties and frequently unreproducible impedance matching of discrete IMPATTs for waveguide operation are considered. In the fabrication approach, the IMPATT structure is embedded in semiinsulating polycrystalline Si. This poly-Si can be deposited simultaneously with the mono-Si layers necessary for device operation during the so-called 'differential epitaxy'. A favourable method for this differential epitaxy of silicon is molecular beam epitaxy (MBE). For this concept highly doped n/sup +/-substrates are used. The double drift IMPATT diode layers are deposited over a patterned SiO/sub 2/ film. A three layer mono-Si zone embedded in poly-Si results. Metallic contacts are evaporated and the p/sup +/-poly-Si layer is removed because of its poor isolation. The poly-Si and top contact are covered with an Au metallisation so that the diode can be matched to a disc resonator in order to make the whole structure act as an oscillator.
Association of Maternal Caffeine Consumption with Decrements in Fetal Growth (2003)

Whether caffeine consumption during pregnancy represents a fetal hazard remains uncertain. The authors report on a large prospective study designed to examine this question. In 1996-2000, 2,291 mothers with singleton livebirths in Connecticut and Massachusetts were evaluated after their first prenatal visit and were questioned about caffeine consumption and important confounding factors. Urine samples were provided to analyze urinary caffeine, cotinine, and creatinine levels. Mothers were followed throughout pregnancy to monitor changes in consumption. Pregnancy outcomes were obtained from medical records. Self-reports of caffeine consumption in the first and third trimesters were not associated with intrauterine growth retardation, low birth weight, or preterm delivery. For every 1 mg/g creatinine increase in urinary caffeine, risk of intrauterine growth retardation was essentially unchanged (odds ratio (OR) = 0.96, 95% confidence interval (CI): 0.85, 1.08). In contrast, a 0.005 mg/g creatinine increase in urinary cotinine significantly increased risk (OR = 1.003, 95% CI: 1.001, 1.005). Mean birth weight was reduced by reported caffeine consumption (-28 g per 100 mg of caffeine consumed daily, 95% CI: -0.10, -0.46, p = 0.001) but not mean gestational age. Decaffeinated coffee did not increase risk for any perinatal outcome. This small decrease in birth weight, observed for maternal caffeine consumption, is unlikely to be clinically important except for women consuming >/=600 mg of caffeine daily (approximately six 10-ounce (1 ounce = 28.3 g) cups of coffee).

Diabetes-Induced Endothelial Dysfunction is Prevented by Long-Term Treatment with the Modified Iron Chelator, Hydroxyethyl Starch Conjugated-Deferoxamine (1997)

Oxygen radicals are believed to play a role in vascular complications of diabetes mellitus. In this study, we evaluated whether long-term treatment with an iron chelator and inhibitor of metal-catalyzed hydroxyl radicals (.OH) could prevent diabetes-induced defects in endothelium-dependent relaxation. Diabetes was induced in Sprague-Dawley rats by injection of streptozotocin. At 48 h after streptozotocin, a subgroup of diabetic rats received daily injections of 50 mg/kg hydroxyethyl starch conjugated-deferoxamine (HES-DFO) for a total of 8 weeks. Long-term treatment with HES-DFO did not modify serum insulin or blood glucose taken at the end of the study; however, a modest reduction in glycosylated hemoglobin was present. In precontracted aortic rings suspended in tissue baths, endothelium-dependent relaxation to acetylcholine was impaired in diabetic rings compared with control rings in the presence or absence of indomethacin. Endothelium-independent relaxation to nitroglycerin was unaltered. Long-term treatment with HES-DFO had no effect on relaxation to nitroglycerin but completely prevented the impaired relaxation to acetylcholine in diabetic rings in either the presence or absence of indomethacin. These data suggest that iron-catalyzed .OH formation contributes to the development of diabetes-associated endothelial dysfunction.
