Neural networks for the no-reference assessment of perceived quality (2005)

Imaging algorithms often require reliable methods to evaluate the quality effects of the visual artifacts that digital processing brings about. We adopt a no-reference objective method for predicting the perceived quality of images in a deterministic fashion. JPEG coding provides a significant and interesting case study. To enhance the coherence of the quality estimates with respect to the empirical evidence of the perceptual phenomenon, the system parameters are adjusted using subjective scores obtained from human assessors. Principal component analysis is first used to assemble a set of objective features that best characterize the information in image data. Then a neural network, based on the circular backpropagation (CBP) model, associates the selected features with the corresponding predictions of quality ratings and reproduces the scores process of human assessors. The neural model enables one to decouple the process of feature selection from the task of mapping features into a quality score. Results on a public database for an image-quality experiment involving JPEG-compressed images and comparisons with existing objective methods confirm the approach effectiveness.

The fate of acetyl groups and sugar components during the digestion of grass cell walls in sheep (1977)

Summary The digestibilities of grass cell wall constituents determined in a digestion trial were compared with those obtained by suspending various isolated cell wall preparations in nylon bags in the rumen of a sheep. Particular attention was paid to acetyl groups and to individual sugars, which were determined in both cases by gas liquid chromatography. For dried grass and hay in the digestion trial the cell wall constituents showed digestibilities decreasing in the following order: arabinose, galactose, glucose, xylose, acetyl, lignin. For a leaf cell wall preparation derived from all cell types except mesophyll, the nylon bag technique allowed the same order of digestibilities; rhamnose and uronic acids were also measured and found to be rapidly digested. Mesophyll cell walls placed in nylon bags were more readily digested than non-mesophyll. All the sugars, and also acetyl groups, were digested to the same extent. In a grass cell wall preparation isolated from sheep faeces, tested similarly, xylose and glucose were digested to the same extent, but acetyl groups were less digested. Removal of acetyl groups, using sodium ethoxide, which left the sugar composition and lignin content unchanged, increased the digestibility particularly of the cell walls from faeces. The results are discussed with reference to the relationship between cell wall composition and digestibility.
INDUSTRIAL DESIGN APPLICATION FOR POWER DISTRIBUTION OVER EXTRA-LONG DISTANCES (2001)

Typically, large loads associated with petroleum distribution systems are located in a relatively confined plant area. Scattered distribution systems often are not very large capacity. the combination of large industrial requirements coupled with the geographic requirements of a utility system created a challenging design.
The Two-Component Regulatory System <i>senX3-regX3</i> Regulates Phosphate-Dependent Gene Expression in <i>Mycobacterium smegmatis</i> (2007)

Phosphate import is required for the growth of mycobacteria and is regulated by environmental inorganic phosphate (P(i)) concentrations, although the mechanism of this regulation has not been characterized. The expression of genes involved in P(i) acquisition is frequently regulated by two-component regulatory systems (2CRs) consisting of a sensor histidine kinase and a DNA-binding response regulator. In this work, we have identified the senX3-regX3 2CR as a P(i)-dependent regulator of genes involved in phosphate acquisition in Mycobacterium smegmatis. Characterization of senX3 mutants with different PhoA phenotypes suggests a dual role for SenX3 as a phosphatase or a phosphodonor for the response regulator RegX3, depending upon P(i) availability. Expression of PhoA activity required phosphorylation of RegX3, consistent with a role for phosphorylated RegX3 (RegX3 approximately P) as a transcriptional activator of phoA. Furthermore, purified RegX3 approximately P bound to promoter sequences from phoA, senX3, and the high-affinity phosphate transporter component pstS, demonstrating direct transcriptional control of all three genes. DNase I footprinting and primer extension analyses have further defined the DNA-binding region and transcriptional start site within the phoA promoter. A DNA motif consisting of an inverted repeat was identified in each of the promoters bound by RegX3 approximately P. Based upon our findings, we propose a model for P(i)-regulated gene expression mediated by SenX3-RegX3 in mycobacteria.
Speaker-centric score normalisation and time pattern analysis for continuous speaker verification (2002)

In this paper we introduce the concept of a continuous speaker verification system in a mobile phone environment. The system verifies the speaker during the phone call. We discuss speaker-centric score normalisation and time pattern analysis which extends a speaker verification system to allow continuous verification. Experiments showed that speaker-centric score normalisation improved performance. Moreover, it standardises the target score distribution to allow the accurate prediction of miss probabilities. The performance evaluation of time pattern analysis revealed an impostor locking of 95% while the target speakers remained unlocked.
Vocal Mimicry and the Evolution of Bird Song (1975)

SUMMARYRobinson, F. N. 1975. Vocal mimicry and the evolution of bird song. Emu 75: 23–27.Vocal mimicry in birds appears to have evolved to augment the songs of some species. Its incorporation into the songs of lyrebirds depends on the mimic using the model's calls at a time when they have no biological significance to the model and on the physical characteristics of the model's calls being sufficiently like those of the mimic to convey the same information to territorial rivals and females as do the mimic's own calls.The Ptilonorhynchidae on the other hand use mimicry of predators to enhance the threatening nature of a song that cannot include loudness for this purpose because lengthy display at a bower jeopardizes the bird.Mimicry is normally suppressed by the need for specific identification but may emerge as a displacement activity where a species is exposed to predation or disturbance as a result of the need to make a loud and continuous noise and can be retained in song if it is biologically advantageous.Studies of the Menuridae and Atrichornithidae give examples of the selective development of own song with or without mimicry in relation to the timing of breeding and geographical distribution of mimic and model.

Relative Navigation for the Hubble Servicing Mission using Reflected GPS Signals (2007)

Autonomous rendezvous and docking is an important research area within the new exploration missions called forth by NASA. Relative navigation requires special sensors and algorithms to provide the necessary information. It may be possible to use reflected GPS signals as a source of ``free'' relative navigation measurements. Thus requiring no additional hardware except added algorithmic complexity. This thesis examines the use of an extended Kalman filter with reflected GPS measurements as a form of bi-static radar. It compares two different types of dynamic models, an absolute orbit model versus Hill's equations. The scenarios were implemented in Matlab using Satellite Toolkit to generate a high fidelity truth model. The thesis also examines visibility of reflected signals in a typical Hubble rendezvous scenario. This is done by approximating the Hubble as a cylinder, and using geometric optics to predict the reflective pattern.
Passive ring resonator laser gyroscope (1977)

A new method of measuring inertial rotation is presented. It is based on the use of a passive ring resonator as the rotation sensing element and an external laser for measuring the difference between the clockwise and counterclockwise lengths of the resonator. Preliminary performance data is included.
Pathways database system (2003)

During the next phase of the Human Genome Project, research will focus on functional studies of attributing functions to genes, their regulatory elements, and other DNA sequences. To facilitate the use of genomic information in such studies, a new modeling perspective is needed to examine and study genome sequences in the context of many kinds of biological information. Pathways are the logical format for modeling and presenting such information in a manner that is familiar to biological researchers. In this paper we present an integrated system, called Pathways Database System, with a set of software tools for modeling, storing, analyzing, visualizing, and querying biological pathways data at different levels of genetic, molecular, biochemical and organismal detail. The novel features of the system include: a) genomic information integrated with other biological data and presented from a pathway, rather than from the DNA sequence, perspective; b) design for biologists who are possibly unfamiliar with genomics, but whose research is essential for annotating gene and genome sequences with biological functions; c) database design, implementation and graphical tools which enable users to visualize pathways data in multiple abstraction levels, and to pose predetermined queries; and d) an implementation that allows for web(XML)-based dissemination of query outputs (i.e., pathways data) to researchers in the community, giving them control on the use of pathways data.

How to Rate Crude Oils for Alkaline Flooding Potential: A Study Based on 239 Crude Oils (1993)

ABSTRACT This paper presents an overview of results of 239 crude oils which have been tested over a 10-yaar period. The oils represent 83 different formations. Analysis data from the Department of Energy (DOE) was available for 103 of the oils. Alkaline reactivity was correlated with crude oil composition and properties. Oils that contained a high proportion of vacuum distillate and components that tend to concentrate in the vacuum distillate had a high probability of alkaline reactivity. High molecular weight aromatics positively influenced alkaline reactivity, while paraffinic components had the opposite effect. Chemical properties correlated with alkaline reactivity more strongly than physical properties. A rating system based on factors that influence reactivity was constructed and applied to groups of oils. The rating system should be used as an initial screening tool for alkaline flooding potential.
Deposits of immunoglobulins, complement, and immune complexes in inflamed human gingiva (1987)

Gingival biopsy specimens from 20 patients with moderate to advanced periodontitis were obtained from inflamed sites with pockets of 5 mm or more. Sections were studied by an immunofluorescence technique, using polyclonal rabbit or goat anti-IgG, anti-IgM, anti-C1q, anti-C3a, and anti-C3c and mouse monoclonal anti-C9. Prewashed ethanol-fixed and nonwashed ethanol-fixed or frozen specimens showed many plasma cells staining for IgG or C3a, suggesting the possible occurrence of a receptor for C3a in plasma cells. Plasma cells containing IgM were also seen. Deposits of IgG and IgM with C1q, C3a, and C3c, suggesting immune complexes, were demonstrated by a double staining technique, combining fluorescein (FITC) or rhodamine (TRITC)-labeled anti-immunoglobulins with TRITC- or FITC-conjugated antibody to C3a, C3c, and C1q. The complexes were located mainly within or around vessel walls. Deposits of C3a and C1q were found in vessel walls, in the basement membrane zone of oral gingival epithelium, or diffusely distributed in the tissues. Deposits of C3c were found to a lesser extent and only in vessel walls. Mouse monoclonal anti-C9, visualized with FITC-labeled rabbit anti-mouse and swine anti-rabbit antiserum, showed granular deposits of C9, mainly in the basement membrane zone of oral gingival epithelium. The study indicates the involvement of immune complex vasculitis in inflammatory periodontal lesions. Also, our observations of the occurrence of deposits of complement factors support the hypothesis that complement factors play an important role in the immunopathology of the periodontal lesion.
A Spectral Graph Theoretic Approach for Monitoring Multivariate Time Series Data From Complex Dynamical Processes (2016)

The objective of this paper is to monitor complex process dynamics manifest in multivariate (multidimensional) time series data using a spectral (algebraic) graph theoretic approach. We test the hypothesis that the spectral graph-based topological invariants detect incipient process drifts earlier [lower average run length (ARL <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> )] and with higher fidelity (consistency of detection) when compared with the conventional statistics-based approaches. The presented approach maps a multidimensional sensor data stream X <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">N×d</sup> (visualize N as time and d as the number of sensors) as an unweighted and undirected network graph G(V, E), indexed by its vertices V and edges E, i.e., X → G(V, E). The rationale is that the graph-based topological invariants are surrogate representatives of the system state. We compare the monitoring performance of spectral graph theoretic invariants with conventional statistical features in an exponentially weighted moving average control chart setting. The practical utility of the approach is substantiated in the context of process monitoring in two advanced manufacturing scenarios, namely, ultraprecision machining (UPM) and semiconductor chemical mechanical planarization. These studies corroborate the hypothesis that graph theoretic invariants, when used as monitoring statistics, lead to lower ARL <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> and more consistent detections in contrast to conventional statistical features. For instance, in the UPM case, the fault detection delay using graph theoretic invariants is less than 160 ms, compared with over 8 s of delay with statistical features.

Perfluorooctanesulfonate Degrades in a Laccase-Mediator System (2018)

Perfluorooctanesulfonate (PFOS) is a compound that has wide applications with extreme persistence in the environment and the potential to bioaccumulate, and could induce adverse effects to ecosystems. We investigated the degradation of PFOS by laccase-induced enzyme catalyzed oxidative humification reactions (ECOHRs) using 1-hydroxybenzotriazole (HBT) as a mediator. Approximately 59% of PFOS was transformed over 162 days of incubation, and the reaction appeared to follow a pseudo-first-order model with reaction rate constant of 0.0066/ d ( r<sup>2</sup> = 0.87) under one condition tested. Using differential absorption spectra and theoretical simulation, we elucidated the interaction between Cu<sup>2+</sup>/Mg<sup>2+</sup> and PFOS, and proposed that Cu<sup>2+</sup> and Mg<sup>2+</sup> could serve as a bridge to bring the negatively charged PFOS and laccase to proximity, thus increasing the chance of radicals that are released from laccase to reach and react with PFOS. In addition, density functional theory modeling showed that PFOS complexation to the metal ions could unlock its helical configuration and decrease the C-C bond energy of PFOS. These changes allow the attack of PFOS C-C backbone by radicals to become easier. On the basis of products identification, we proposed that direct attack of PFOS by the HBT radical initiated the free radical chain reaction processes and led to the formation of fluoride and partially fluorinated compounds. These results suggest that ECOHR is a potential pathway by which PFOS could be degraded in the environment, and it may make a viable approach to remediate PFOS contamination via amendment of appropriate enzymes and mediators.
Successful Application of New LWD Platform Provides Integrated Real-Time Formation Evaluation in the Mediterranean Reservoirs (2009)

Abstract As the global power scenario changes with increased demand for oil and gas, remote and challenging (deepwater offshore, high pressure-high temperature, high-angle wells) locations are drilled in an ever-demanding exploration effort with minimum or no experience in the area. To meet the demand and associated financial implications, operators are drilling highangle wells that require special care from well stability, completion, and formation evaluation, to name a few. Complex reservoirs require complex trajectory and therefore proper well placement. To place a well accurately, the evaluation of acquired data requires real-time interpretation. In Egypt, Petrobel is following the trend and has been drilling deviated wells to enhance production in the Mediterranean by using a new logging while drilling (LWD) platform for formation evaluation. The data delivered by this service includes not only traditional measurements such as resistivity, density, neutron porosity, gamma ray, and caliper, but also induced spectroscopy and sigma. The sigma measurement is used for saturation evaluation independent of resistivity. The availability of two independent saturation estimations provides additional confidence. Spectroscopy provides formation mineralogy and accurate clay fraction, which enhances shaly sand interpretation. Formation evaluation in real time provides accurate estimates of hydrocarbon in place and allows for comprehensive decision making. The field is approximately 70 km from the coast of Alexandria, Egypt. The main reservoir is predominantly sandstone with gas and condensate. Highlighted in this study: Real time interpretation based on capture spectroscopy and sigma combined with the traditional measurements.Lithologic and mineralogic evaluation using capture gamma-ray spectroscopy measurements on LWD in real time.Independent gas saturation estimates from both resistivity and sigma measurements on LWD in real time.Real time formation evaluation requires minimum inputs from user, making it a powerful tool for operators in the decision making process.
Congestive Cardiomyopathy in the Canine (1984)

Diseases of the myocardium can be classified either as primary or secondary. Primary cardiomyopathies include idiopathic congestive or hypertropic forms. Causes of secondary cardiomyopathies are primary, systemic diseases, the most common of which are infectious, metabolic, toxic, ischemic, and neoplastic diseases that cause some myocardial damage.
A Ribosomal Gene Mutation in Streptomycin-ResistantMycobacterium tuberculosis Isolates (1993)

Colleagues-In Escherichia coli the bases from 909 to 915 of the 16S rRNA are important for streptomycin binding [I, 2], and mutations in this area protect against streptomycin inhibition of ribosomal function in vitro We have detected an A-G mutation at position 866 in the 16S rRNA gene ofa streptomycin-resistant clinical isolate of Mycobacterium tuberculosis that is not present in published mycobacterial 16S rRNA gene sequences. This position corresponds to position 913 in the E. coli 16S rRNA genome, and the mutation may be responsible for the streptomycin-resistant phenotype. Ten additional streptomycin-resistant M. tuberculosis isolates were screened for this mutation; I of these also contains the A-G mutation.
Salient Objects in Clutter: Bringing Salient Object Detection to the Foreground (2018)

We provide a comprehensive evaluation of salient object detection (SOD) models. Our analysis identifies a serious design bias of existing SOD datasets which assumes that each image contains at least one clearly outstanding salient object in low clutter. The design bias has led to a saturated high performance for state-of-the-art SOD models when evaluated on existing datasets. The models, however, still perform far from being satisfactory when applied to real-world daily scenes. Based on our analyses, we first identify 7 crucial aspects that a comprehensive and balanced dataset should fulfill. Then, we propose a new high quality dataset and update the previous saliency benchmark. Specifically, our SOC (Salient Objects in Clutter) dataset, includes images with salient and non-salient objects from daily object categories. Beyond object category annotations, each salient image is accompanied by attributes that reflect common challenges in real-world scenes. Finally, we report attribute-based performance assessment on our dataset.
