SPARQL query rewriting for implementing data integration over linked data (2010)

There has been lately an increased activity of publishing structured data in RDF due to the activity of the Linked Data community. The presence on the Web of such a huge information cloud, ranging from academic to geographic to gene related information, poses a great challenge when it comes to reconcile heterogeneous schemas adopted by data publishers. For several years, the Semantic Web community has been developing algorithms for aligning data models (ontologies). Nevertheless, exploiting such ontology alignments for achieving data integration is still an under supported research topic. The semantics of ontology alignments, often defined over a logical frameworks, implies a reasoning step over huge amounts of data, that is often hard to implement and rarely scales on Web dimensions. This paper presents an algorithm for achieving RDF data mediation based on SPARQL query rewriting. The approach is based on the encoding of rewriting rules for RDF patterns that constitute part of the structure of a SPARQL query.
The Relationships Among Various Nonnegative Matrix Factorization Methods for Clustering (2006)

The nonnegative matrix factorization (NMF) has been shown recently to be useful for clustering and various extensions and variations of NMF have been proposed recently. Despite significant research progress in this area, few attempts have been made to establish the connections between various factorization methods while highlighting their differences. In this paper we aim to provide a comprehensive study on matrix factorization for clustering. In particular, we present an overview and summary on various matrix factorization algorithms and theoretically analyze the relationships among them. Experiments are also conducted to empirically evaluate and compare various factorization methods. In addition, our study also answers several previously unaddressed yet important questions for matrix factorizations including the interpretation and normalization of cluster posterior and the benefits and evaluation of simultaneous clustering. We expect our study would provide good insights on matrix factorization research for clustering.
Application of the Concurrent Subspace Design framework to aircraft brake component design optimization (1998)

The Concurrent Subspace Design (CSD) framework has been used to conduct a preliminary design optimization of an aircraft landing gear subsystem. The application required the implementation of the MDO framework with existing industrial analysis software. The CSD framework employs artificial neural networks to provide approximations to the design space, which are the means of coordinating design decisions in the individual disciplines. This approach was applied to the design of an aircraft brake actuation system which contains continuous and discrete design variables. The results demonstrate that the mixed CSD framework was able to efficiently identify improved designs. This study also demonstrated that the CSD framework can be exploited using existing engineering analysis methods.

Automatic basketball tracking in broadcast basketball video (2012)

We proposed and implemented an automatic basketball detection and tracking system for broadcast basketball video recorded with a single pan-tilt-zoom camera, using knowledge of player tracking information. The task is challenging because the basketball is blurred due to the camera and the ball's fast movements, and broadcast video compression; also the motion pattern of the basketball is complicated and the ball is hard to distinguish from the cluttered background region. We incorporated three independent detection approaches to detect the basketball and tracked the basketball using the Kalman Filter, and then we analyzed the tracklets and selected the passing / shooting tracklets and inferred the player possession information. We tested the system using 830 frames in broadcast basketball video, and our system demonstrated the ability to track some passing / shooting actions and then infer the player who controls the ball. The system is a first attempt to extend the intelligent basketball tracking system to include basketball tracking and player possession inference. Our proposed methodologies can be extended to other intelligent sports analysis systems, even when the ball movement in the sport is not constrained in two dimensional space.
The far upstream chicken lysozyme enhancer at -6.1 kilobase, by interacting with NF-M, mediates lipopolysaccharide-induced expression of the chicken lysozyme gene in chicken myelomonocytic cells. (1994)

Macrophages respond to lipopolysaccharide (LPS) with the activation of various genes, including the lysozyme gene. Here, we show that the level of lysozyme mRNA increases following treatment of chicken myelomonocytic HD11 cells with LPS. By transient and stable transfection of the chloramphenicol acetyltransferase (CAT) gene controlled by regulatory elements of the lysozyme gene, we identified a subfragment of the -6.1 kilobase (kb) lysozyme enhancer that mediates the LPS-induced lysozyme expression. This subfragment contains two elements (D and E), each of which matches the highly degenerate consensus sequence of binding sites for C/EBP-like transcription factors. Furthermore, we found protein complexes to interact with elements D and E whose binding activity to elements D and E is LPS-inducible in myelomonocytic HD11 cells. Immunomobility shift assays show that NF-M, a myeloid-specific C/EBP beta-related transcription factor is an essential component of these protein complexes. Mutations of the C/EBP binding sites within D and E cause a reduction of basal activity and abolish LPS responsiveness of the -6.1 kb lysozyme enhancer. These results show that the -6.1 kb lysozyme enhancer, in addition to its role in cell type-specific expression, can mediate, by interacting with NF-M, LPS-induced expression of the lysozyme gene in chicken myelomonocytic cells.
Core-Corona Separation in Ultrarelativistic Heavy Ion Collisions (2007)

Simple geometrical considerations show that the collision zone in high energy nuclear collisions may be divided into a central part ("core"), with high energy densities, and a peripheral part ("corona"), with smaller energy densities, more like in pp or pA collisions. We present calculations that allow us to separate these two contributions, and which show that the corona contribution is quite small (but not negligible) for central collisions, but gets increasingly important with decreasing centrality. We will discuss consequences concerning results obtained in heavy ion collisions at the BNL Relativistic Heavy Ion Collider and CERN Super Proton Synchrotron.
Effects of propagation on the return stroke radiation fields (1987)

It is shown that a simple mathematical model could be used to predict the propagation effects on the radiation fields to a high accuracy under most of the cases of interest. Propagation effects on a large collection of radiation fields from first return strokes measured over seawater are studied by using this mathematical model. The theoretical results are compared with the available experimental data and a good agreement is found between them. One important conclusion of the study is that the localization of the lightning return strokes by the time of arrival method could be greatly improved, under low conducting ground conditions, by selecting one of the following as reference points in the time measurement: (1) a point in the initial rising part of the radiation field whose amplitude is less than about 50% of the initial peak or (2) the peak of the first or the second derivative of the radiation field.
Effect of electrical stimulation on foot skin perfusion in persons with or at risk for diabetic foot ulcers (1998)

The failure of foot wounds to heal results in 54,000 people with diabetes having to undergo extremity amputations annually. Therefore, treatment is needed to speed healing in people with diabetes in order to reduce the need for amputation. This study tested the effect of high-voltage pulsed current on foot blood flow in human beings who are at risk for diabetic foot ulcers. Neuropathy, vascular disease, Wagner Class, glucose, gender, ethnicity, and age were measured. A sample of 132 subjects was tested using a repeated-measures design. A baseline transcutaneous oxygen level was obtained; stimulation was applied, and transcutaneous oxygen measurements were recorded at 30- and 60- minute time intervals. The grouped foot transcutaneous oxygen levels decreased (F = 5.66, p =. 0039) following electrical stimulation. Analysis of variance (Scheffe, p <.05) showed that initial transcutaneous oxygen was significantly higher than subsequent readings. However, oxygen response was distributed bimodally: 35 (27%) subjects showed increased transcutaneous oxygen (mean 14.8 mm Hg), and 97 (73%) experienced a decreased transcutaneous oxygen reading (mean 12.2 mm Hg). Logistic regression analysis did not explain these differences. Although this treatment appears to increase blood flow in a subset of patients, further study is needed to identify probable mechanisms for this response.
Routing Service Quality -- Local Driver Behavior Versus Routing Services (2013)

Mobile location-based services is a very successful class of services that are being used frequently by users with GPS-enabled mobile devices such as smartphones. This paper presents a study of how to exploit GPS trajectory data, which is available in increasing volumes, for the assessment of the quality of one kind of location-based service, namely routing services. Specifically, the paper presents a framework that enables the comparison of the routes provided by routing services with the actual driving behaviors of local drivers. Comparisons include route length, travel time, and also route popularity, which are enabled by common driving behaviors found in available trajectory data. The ability to evaluate the quality of routing services enables service providers to improve the quality of their services and enables users to identify the services that best serve their needs. The paper covers experiments with real vehicle trajectory data and an existing online navigation service. It is found that the availability of information about previous trips enables better prediction of route travel time and makes it possible to provide the users with more popular routes than does a conventional navigation service.
Azasteroids. Part X. Synthesis of 3,4-dihydro-8-methoxybenzo[c]phenanthridin-1(2H)-one (1973)

1-Hydroxy- and 1-oxo-1,2,3,4-tetrahydrobenzo[c]phenanthridines have been obtained through benzyne cyclisation of anils and reduced anils derived from 5-amino-1-tetralone and appropriate 2-chlorobenzaldehydes.
Control of Norway rats in sewer and utility systems using pulsed baiting methods (1998)

There were 1,288 sewer and 235 other utility manholes baited to control Norway rat (Rattus norvegicus) populations in downtown Boston using pulsed-baiting methods. About 15% of all sewer, 18% of phone, and 26% of electric manholes had rat activity. Sewer populations were most associated with residential areas with low flow, small diameter (<61 cm) brick sewers; in those circumstances, up to 38% of manholes had rat activity. Bait consumption in sewers (high risk areas) was 91% below baseline, five months after the fourth baiting period. Bait consumption and the number of active sewer holes were 96% and 87% below baseline, respectively, when seasonal maintenance baiting was last initiated. Reinfestation of phone/electric manholes was so minimal that maintenance baiting was not necessary or cost-effective. Subsurface baiting should be an integral part of urban rodent control programs.
Biosynthetic Skin Substitute vs. 1% Silver Sulfadiazine for Treatment of Inpatient Partial-thickness Thermal Burns (1988)

When used appropriately on superficial or moderate-depth partial-thickness burns, Biobrane significantly decreased total healing time to complete reepithelialization, reduced pain, and was associated with decreased nursing time and costs when compared to 1% silver sulfadiazine cream. Care must be used in selecting wounds for Biobrane therapy. They must be fresh, noninfected, and free of eschar and debris with a moist, sensate surface that demonstrates capillary blanching and refill. Wounds must be inspected regularly for nonadherence and signs of infection. Early fluid accumulation requires prompt aspiration. Biobrane should be removed if fluid reaccumulates or the Biobrane becomes nonadherent at any time after 48 hours. When used appropriately, Biobrane offers significant advantages over conventional therapy of acute partial-thickness burns.
Swenson's Pediatric Surgery (1981)

The fourth edition of<i>Swenson's Pediatric Surgery</i>has just been published. It differs significantly from previous editions and from other major textbooks of pediatric surgery. The fourth edition is a single-volume work rather than the previous two-volume set. The price is a bargain in today's book market. The editor, who wrote most of the book, departed from the style used so often in medical textbooks. This is a problem-oriented volume, written for the surgical house officer and the practicing general surgeon who sees an occasional pediatric patient. Common pediatric surgical problems are clearly and concisely defined, and their treatment described. The author inserts his own preference for methods of treatment and the reasons for his preferences, but not at the expense of alternative methods of therapy. This book gains in readability from close editing and attention to the style and content. Absent from this text are sections on pediatric cardiac
Condition Assessment of Contacts in Gas-Insulated Substations (2004)

A new method for assessing the condition of electric contacts and joints inside gas-insulated substations (GISs) that overcomes the limitations of conventional diagnostic methods is proposed. The contact resistance in degraded or overstressed electrical contacts varies slightly when currents of different amplitudes are passed. The diagnostic method is based on detecting this nonlinear behavior. For testing of the contacts in large GIS, excitation currents up to several thousand amperes are required. By using a capacitor-based current supply, such currents can be achieved with a portable source. The testing can be carried out without dismantling the GIS. No earlier measurements or manufacturer specifications are required. In full-scale testing under realistic operating conditions on 145-420 kV GIS using prototype instrumentation a very good sensitivity for detecting contact degradation in an early stage was obtained.
Gaussian processes for source separation (2008)

In this paper we present a probabilistic method for source separation in the case where each source has a certain unknown temporal structure. We tackle the problem of source separation by maximum pseudo-likelihood estimation, representing the latent function which characterizes the temporal structure of each source by a random process with a Gaussian prior. The resulting pseudo-likelihood of the data is Gaussian, determined by a mixing matrix as well as by the predictive mean and covariance matrix that can be easily computed by Gaussian process (GP) regression. Gradient-based optimization is applied to estimate the demixing matrix through maximizing the log-pseudo-likelihood of the data. Numerical experiments confirm the useful behavior of our method, compared to existing source separation methods.
Diphenylhydantoin and Pulmonary Function (1979)

Thirty-nine epileptic patients underwent pulmonary function testing. Twenty-one of these patients, ranging in age from 16 to 44 years, had taken diphenylhydantoin (DPH) for 2 to 17 years. Eighteen patients, who had taken other anticonvulsants for similar time periods served as controls. Five patients in the DPH group had lung volume abnormalities, four had abnormal airway function, and five had abnormalities of alveolar gas mixing. One patient in the control group had lung volume abnormalities, two had abnormal airway function, and five had abnormalities of alveolar gas mixing. Statistical analysis revealed no significant differences between the groups, or between either group and predicted values.
Susceptibility of five species of fish to <i>Edwardsiella ictaluri</i> (1983)

Abstract. Five species of fingerling fish, channel catfish, Ictalurus punctatus , tilapia, Sarotherodon aureus , golden shiner, Notemigonus crysoleucas , largemouth bass, Micropterus salmoides and bighead carp, Aristichthys nobilis , were tested to determine their susceptibility to the bacterium, Edwardsiella ictaluri , at 26°C, Channel catfish demonstrated high susceptibility to E. ictaluri as 100% of those fish injected with 1.5 × 10 3 cells died within 10 days. Tilapia demonstrated slight susceptibility to the pathogen while golden shiner, bighead carp and largemouth bass were not susceptible. E. ictaluri was isolated from a higher percentage of peritoneal cavities, livers and kidneys of channel catfish than of other species. Sequential growth of E. ictaluri in the liver of channel catfish is described.
Preparation of core/shell structured NiO-based ceramics and their dielectric properties (2005)

High-permittivity dielectric core/shell structured Li0.01SixNi0.99−xO ceramics (abbreviated as LSNO) have been successfully prepared. Analyses of the ceramic microstructure and composition indicate that the dopants of SiO2 are mainly dispersed into the grain boundaries and exist as the insulating Ni2SiO4 phase. All the LSNO ceramic samples exhibit high permittivity, and the permittivity reaches about 1.2 × 104 for the LSNO-1 sample. The concentration of Si has a remarkable effect on the dielectric properties of the LSNO ceramics. The origin of the high permittivity observed in these LSNO ceramics is attributed to the Maxwell–Wagner polarization mechanism and a thermally activated mechanism.

Cell-free synthesis of hyaluronic acid in Marfan syndrome. (1979)

The cell-free synthesis of hyaluronic acid has been demonstrated in extracts of cultured human fibroblasts. Preparations from fibroblasts of normal individuals as well as those from patients with Marfan syndrome incorporate glucuronic acid and N-acetylglucosamine from their UDP derivatives into hyaluronic acid. Extracts from Marfan fibroblasts demonstrate 3 to 10 times more total and specific hyaluronic acid synthetase activity than do preparations from normal fibroblasts. All synthetic activity was found in particulate fractions with the bulk of activity localized in material sedimenting as large membrane fragments. Marfan and normal preparations exhibited similar properties with respect to substrate, cofactor, pH requirements, and heat stability. Neither the Marfan nor normal enzyme systems could be stimulated by exogenous acceptors, nor did either preparation contain a soluble factor which stimulated or inhibited the enzymic activity of the other. The genetic defect in Marfan syndrome appears to result in increased activity of hyaluronic acid synthetase without demonstrable changes in properties of the particulate enzymes involved.
HorizonNet: Learning Room Layout with 1D Representation and Pano Stretch Data Augmentation (2019)

We present a new approach to the problem of estimating the 3D room layout from a single panoramic image. We represent room layout as three 1D vectors that encode, at each image column, the boundary positions of floor-wall and ceiling-wall, and the existence of wall-wall boundary. The proposed network, HorizonNet, trained for predicting 1D layout, outperforms previous state-of-the-art approaches. The designed post-processing procedure for recovering 3D room layouts from 1D predictions can automatically infer the room shape with low computation cost - it takes less than 20ms for a panorama image while prior works might need dozens of seconds. We also propose Pano Stretch Data Augmentation, which can diversify panorama data and be applied to other panorama-related learning tasks. Due to the limited data available for non-cuboid layout, we relabel 65 general layout from the current dataset for finetuning. Our approach shows good performance on general layouts by qualitative results and cross-validation.
Modeling and performance evaluation of 2.4GHz SAW-based pressure sensor (2006)

This paper presents a pressure sensor based on 2.4 GHz surface acoustic wave (SAW) reflective delay line on a 41deg YX LiNbO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> substrate. Coupling of modes (COM) modeling and finite element method (FEM) were used to extract the optimal design parameters. Based on the simulation results, the SAW device with bar type reflectors was fabricated by electron bean lithography, and characterized wirelessly using the network analyzer. Three sharp peaks with high S/N ratio and few spurious signals were observed from three reflectors. A good agreement was observed between the simulated and measured reflection coefficient S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sub> . Newly employed metal ground shielding covered all over the bonding substrate reduced a coupling loss of propagating SAW to the surrounding atmosphere. Depending on the amount of applied mechanical compression force, the phase angle was modulated. The sensitivity was evaluated as about 2.9deg/kPa.
