Model Driven Interoperability through Semantic Annotations using SoaML and ODM

Abstract Enterprise Interoperability is increasingly being enabled by use of service oriented architectures for the IT systems involved. A combined use of enterprise models, ontologies and service models can facilitate better semantic interoperability of the services being provided and requested. The focus of this paper is to show that service interoperability can be supported through a model driven approach with service oriented systems being described with service models (in SoaML) with semantic annotations to and from ontology models (in ODM)
Diagnosis of sleep apnea by evaluating points distribution in poincare plot of RR intervals

Sleep apnea detection using ECG-derived parameters is non-invasive and inexpensive. This article presents novel ECG-derived features to be used in conjunction with existing standard features for improving the detection of sleep apnea. The features presented here were derived using Poincare plots of RR intervals. Global features are based on counting number of points above, below, and on the identity line in Poincare plot. Furthermore, local features are based on point to point variations relative to the identity line (i.e., temporal information in Poincare plot). Performance of features in detection of apnea was evaluated using k-nearest neighbor, self-organizing map, and multilayer perceptron neural network. The accuracy of classifiers on test set was respectively 88.89%, 77.77%, and 100%.
Synthesis-Applied Highly Selective Tunable Dual-Mode BPF With Element-Variable Coupling Matrix

This paper proposes a unified synthesis methodology and the related architecture for fully passband-tunable dual-mode filters with wide tuning range. The methodology and architecture relate the well-developed frequency-fixed synthesis technologies to tunable filters, and can be applied to any tunable filter design and analysis by an element-variable coupling matrix. This general methodology accounts for bandwidth (BW), center frequency (CF), and return loss (RL) (passband ripple or stopband rejection) tuning, and helps to implement the passband-tunable filter. For validation, a novel tunable dual-mode bandpass filter (BPF) based on the architecture is presented. The proposed filter has the ability to arbitrarily construct the two-pole passband within the frequency tuning range as predicted. In addition, three transmission zeros (TZs) are generated by the proposed structure, which results in a highly selective passband and a reconfigurable stopband. A tunable filter with a tuning range from 0.8 to 1.2 GHz is designed and fabricated. The measured filter presents an elliptic response during the frequency tuning. The 50% CF tuning range (0.8–1.42 GHz) with a constant absolute BW1 dB and a BW1 dB tuning range from 50 to 500 MHz at the fixed CF are measured. Good agreement among matrix calculation, circuit model simulation and measurement demonstrates the validity of the proposed method and structure. In addition, different states of the stopband with the same passband are obtained to further broaden its application.
Filamentary fragmentation in a turbulent medium

We present the results of smoothed particle hydrodynamic simulations investigating the evolution and fragmentation of filaments that are accreting from a turbulent medium. We show that the presence of turbulence and the resulting inhomogeneities in the accretion flow play a significant role in the fragmentation process. Filaments that experience a weakly turbulent accretion flow fragment in a two-tier hierarchical fashion, similar to the fragmentation pattern seen in the Orion Integral Shaped Filament. Increasing the energy in the turbulent velocity field results in more sub-structure within the filaments, and one sees a shift from gravity-dominated fragmentation to turbulence-dominated fragmentation. The sub-structure formed in the filaments is elongated and roughly parallel to the longitudinal axis of the filament, similar to the fibres seen in observations of Taurus, and suggests that the fray and fragment scenario is a possible mechanism for the production of fibres. We show that the formation of these fibre-like structures is linked to the vorticity of the velocity field inside the filament and the filament's accretion from an inhomogeneous medium. Moreover, we find that accretion is able to drive and sustain roughly sonic levels of turbulence inside the filaments, but is not able to prevent radial collapse once the filaments become supercritical. However, the supercritical filaments that contain fibre-like structures do not collapse radially, suggesting that fibrous filaments may not necessarily become radially unstable once they reach the critical line-density.
Bone fracture imaging study with an acoustic technique

Imaging studies of bones are important for orthopaedic doctors to know the physical condition of the bones, to enable them to decide about the treatment of a particular abnormality. Generally, the X-ray technique is used by clinicians to assess the condition of the bone, but this method is cumbersome and has diagnostic limitations, particularly in the case of minor fractures. In order to overcome this problem, an acoustic stress wave technique is developed for the study of bone imaging. This technique is quick, less expensive and reliable for evaluating the inner structure of the bone, layer by layer, non-destructively and non-invasively. This paper describes a comparative study of imaging patterns in normal and fractured bones.
Epidermal Growth Factor, through Alleviating Oxidative Stress, Protect IPEC-J2 Cells from Lipopolysaccharides-Induced Apoptosis

The epidermal growth factor (EGF) has been widely used for protection of stress-induced intestinal mucosa dysfunction. However, whether EGF would alleviate oxidative injury and reduce apoptosis in porcine intestine is not yet known. Therefore, the aim of this study was to investigate the effect of EGF on lipopolysaccharides (LPS)-induced induction of oxidative stress and ensuing apoptosis in the porcine intestinal epithelial cell line, IPEC-J2. The present study showed that EGF significantly increased cell viability and decreased the LPS-induced induction of apoptosis, dehydrogenase (LDH) release and malonaldehyde (MDA) production. EGF also (i) decreased expression of the pro-apoptotic genes Fas, Bax, Cascase-3, Cascase-8, Cascase-9, and proteins such as P53, Fas, Bax, Caspase3; (ii) increased antiapoptotic protein B-cell lymphoma 2 (Bcl2) expression; (iii) increased mRNA levels of the nuclear factor erythroid 2-related factor 2 (Nrf2) related genes Nrf2, manganese superoxide dismutase (SOD2), catalase (CAT), glutathione peroxidase (GSH-Px), heme oxygenase (HO-1) and quinone oxidoreductase (NQO1); (iv) protein level of Nrf2-realeted proteins Nrf2, HO-1, NQO1; and (v) total antioxidant capacity (T-AOC), CAT, SOD, GSH-Px concentrations. Collectively, our results indicated that EGF enhanced Nrf2 protein expression, and upregulated the expression of phase II metabolizing enzymes (such as HO-1 and NQO1) and antioxidative enzymes (SOD, CAT and GSH-Px) to alleviate oxidative injury, and then protect IPEC-J2 cells from apoptosis induced by LPS.
Sca 4 in com

Material and methods. Models were fabricated in 3 materials (polymethyl methacrylate [Telio CAD], titanium, and zirconia) and reference scanned with an industrial optical scanner. The models were scanned with intraoral scanners (3M Lava COS, Cerec AC/Bluecam, E4D, and iTero). A thick layer of coating was applied and scanned (3M Lava COS). Further evaluation on a gypsum cast was undertaken for the E4D system. Data were evaluated by using 3-dimensional analysis with “3D compare” software commands (3D compare analysis) regarding standard, mean, and maximum deviations, with subsequent statistical analysis.
Two-dimensional velocity estimation for Doppler optical coherence tomography

In this paper we demonstrate a new algorithm for use in Doppler Optical Coherence Tomography (DOCT) to allow the detection of flow with a peak velocity of over 1.5 m/s. Previous Doppler estimation methods have utilized a transverse Kasai (TK) autocorrelation technique which computes the phase difference between points adjacent in time at the same spatial location, hereon referred to as transversely adjacent points. The maximum detectable TK velocity is low due to the small axial scanning frequency, fa which creates aliasing. To overcome the low sampling rate, we propose using data acquired in the axial direction which has a sampling rate orders of magnitude larger. Taking an autocorrelation in the depth, or axial direction, yields a quantity that can be related to the mean backscattered frequency. We demonstrate that through subtraction of the axial autocorrelation of a moving scatterer from that of a stationary scatterer at the same spatial location, one is able to obtain the Doppler shift with a much higher non-aliased limit. We have defined this method the axial Kasai (AK) technique. Through use of the AK, we demonstrate maximum non-aliased Dopler frequency estimate on a time domain DOCT system to be increased from the TK limit of ±4 kHz to the AK limit of ±1.6 MHz. In contrast to the high detection range of the AK, the TK maintains superior velocity resolution for low flow rates. Through a combined approach with the AK we have demonstrated a dynamic frequency range of over 100 dB with a velocity detection range from 10 &mgr;m/s to over 1.5 m/s. The velocity range has been extended to span both microcirculation and cardiac blood velocities.
Distribution and mobility of spherical opaline phytoliths in a podzol (Podosol)

The mobility of phytoliths (opaline silica bodies in plants) once in the soil is a result of bioturbation, mechanical mixing and pervection, or movement through soil pores. Previous opal phytolith studies have examined the formation of three main Phytolith Depth Functions (PDFs, Hart and Humphreys 2003). The Type-2 PDF, which has a rise in abundance at depth, is typically found where a barrier causes a build up of phytoliths above it or where a buried soil is encountered. This PDF may be found in podzols where pans form a barrier to further migration of phytoliths. What is not known is how changes in packing density affects the distribution pattern of phytoliths with different shapes (spherical, cylindrical, platey etc.). The present study examines variations in the diameters of spherical phytoliths (spheroids) with depth. It shows a rise in median spherical diameter in the A with increasing soil bulk density i.e. increased packing. Previous fabric studies indicated an increase in interstitial finer material with depth, with the movement of larger sphericals increasingly hindered and retained in that part of the soil. However, as the soil pore diameter is progressively reduced, median spherical diameter falls in the Bhs horizon. Beneath the Bhs the median spherical diameter rises again. This is attributed to the migration of spheroids before the development of the iron pan which is supported by the greater degree of weathering and hence age of these phytoliths.
A very low bit rate algorithm based on hierarchical subband scanning

A very low bit rate algorithm based on hierarchical partition of subbands in the wavelet domain is proposed. The algorithm uses the set partitioning technique to sort the transformed coefficients. The threshold of each subband is calculated and the subbands scanning sequence is determined by the magnitude of the thresholds which establish a hierarchical scanning not only for the set of coefficients with large magnitude, but also for the subbands. The algorithm is less complex computationally than SPIHT and JPEG2000. Results show that the present algorithm provides good image quality for very low bit rates.
Assessment of Nutritional Status of Infants Living in Arsenic-Contaminated Areas in Bangladesh and Its Association with Arsenic Exposure

Data is scarce on early life exposure to arsenic and its association with malnutrition during infancy. This study followed the nutritional status of a cohort of 120 infants from birth to 9 months of age in an arsenic contaminated area in Bangladesh. Anthropometric data was collected at 3, 6 and 9 months of the infant’s age for nutritional assessment whereas arsenic exposure level was assessed via tube well drinking water arsenic concentration at the initiation of the study. Weight and height measurements were converted to Z-scores of weight for age (WAZ-underweight), height for age (HAZ-stunting), weight for height (WHZ-wasting) for children by comparing with WHO growth standard. Arsenic exposure levels were categorized as <50 μg/L and ≥50 μg/L. Stunting rates (<−2 SD) were 10% at 3 months and 44% at both 6 and 9 months. Wasting rates (<−2 SD) were 23.3% at 3 months and underweight rates (<−2 SD) were 25% and 10% at 3 and 6 months of age, respectively. There was a significant association of stunting with household drinking water arsenic exposure ≥50 μg/L at age of 9 months (p = 0.009). Except for stunting at 9 months of age, we did not find any significant changes in other nutritional indices over time or with levels of household arsenic exposure in this study. Our study suggests no association between household arsenic exposure and under-nutrition during infancy; with limiting factors being small sample size and short follow-up. Difference in stunting at 9 months by arsenic exposure at ≥50 μg/L might be a statistical incongruity. Further longitudinal studies are warranted to establish any association.
Wound-Healing Studies in Cornea and Skin: Parallels, Differences and Opportunities

The cornea and the skin are both organs that provide the outer barrier of the body. Both tissues have developed intrinsic mechanisms that protect the organism from a wide range of external threats, but at the same time also enable rapid restoration of tissue integrity and organ-specific function. The easy accessibility makes the skin an attractive model system to study tissue damage and repair. Findings from skin research have contributed to unravelling novel fundamental principles in regenerative biology and the repair of other epithelial-mesenchymal tissues, such as the cornea. Following barrier disruption, the influx of inflammatory cells, myofibroblast differentiation, extracellular matrix synthesis and scar formation present parallel repair mechanisms in cornea and skin wound healing. Yet, capillary sprouting, while pivotal in proper skin wound healing, is a process that is rather associated with pathological repair of the cornea. Understanding the parallels and differences of the cellular and molecular networks that coordinate the wound healing response in skin and cornea are likely of mutual importance for both organs with regard to the development of regenerative therapies and understanding of the disease pathologies that affect epithelial-mesenchymal interactions. Here, we review the principal events in corneal wound healing and the mechanisms to restore corneal transparency and barrier function. We also refer to skin repair mechanisms and their potential implications for regenerative processes in the cornea.
Dependence of the Texture on the Thermoelectric Properties of C/C Composites

C/C composites with different microstructures were fabricated by microwave chemical vapor infiltration (MCVI) using carbon felt as fiber preform, CH4 as precursor gas and N2 as diluent gas. The different microstructures of C/C composites were characterized by polarizing microscope (PLM), scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffraction (XRD) and Raman spectra. Thermoelectric properties were systematically investigated via thermoelectric performance testing instrument (ZEM-2) and laser thermal conductivity instrument (TC-9000H). The results reveal that positive Seebeck coefficient is obtained from C/C composites with different micro- structures and an important relationship is existed between thermoelectric property and orientation of pyrocarbon. See- beck coefficient, electrical conductivity and thermal conductivity are increased gradually with the texture of pyrocarbon evolved from isotropy, low texture and middle texture to high texture. With the texture being reinforced, it has a more important influence on carriers than on phonons. As a result, the merit ZT is increased with the reinforce of the texture.
Sidelobe-Reduced and Gain-Enhanced Square Patch Antennas With Adjustable Beamwidth Under TM03 Mode Operation

A square patch antenna operating under TM03 mode is proposed in this paper to realize gain enhancement, sidelobe reduction, and adjustable beamwidth by reshaping the surface current distribution on the patch resonator. On the one hand, by introducing transverse slots along the central line of patch, the medial part of out-of-phase longitudinal current is interrupted to circulate with little radiation. In this way, the patch serves as a full-wave dipole rather than a $3\lambda $ /2 one, and thus, the sidelobe level (SLL) in the E-plane is substantially reduced. On the other hand, the slots are installed in proximity to the nonradiative edges and at the patch center, respectively, to arouse distinctive effect on the current densities across the width of patch. Consequently, the beamwidth in the H-plane can be freely adjusted by different configurations of these slots. At last, a square patch antenna with three cascaded slots loaded along the central line is designed, fabricated, and tested. The simulated and measured results show that the directivity of a single proposed patch antenna can achieve as high as 13.3 dB with the SLL reduced to about −20 dB.
Immune tolerance of vector beetle to its partner plant parasitic nematode modulated by its insect parasitic nematode

Immune response of insect vectors to transmitted pathogens or insect hosts against parasites are well studied, whereas the mechanism of tripartite interactions remains elusive. In this study, we investigated the immune interactions of the vector beetle Monochamus alternatus (Ma) to the devastating plant parasitic nematode Bursaphelenchus xylophilus (Bx) and the insect parasitic nematode Howardula phyllotretae (Hp). We report the unique immune mechanism by which the vectorbeetle tolerates many devastating Bx in its trachea, yet that immune tolerance is compromised by the parasitic nematode Hp. Contact with either nematode species triggers epithelial reactive oxygen species (ROS) production in Ma. Only the entry of Bx, not Hp, infection, induces increased expression of antioxidative genes, through which the ROS levels are balanced in the trachea of beetles. Furthermore, we found that up‐regulation of antioxidative genes was induced by the interaction of Toll receptors. In contrast, beetles infected by Hp retain high levels of oxidative stress and melanization in trachea, and as a result, decrease Bx loading. This study highlights the role of Toll receptors in mediating the activation of antioxidative genes in immune tolerance to plant parasitic nematodes, and suggests the use of insect parasites as a biologic control. —Zhou, J., Zhao, L. ‐L. , Yu, H. ‐Y. , Wang, Y. ‐H. , Zhang, W. , Hu, S. ‐N. , Zou, Z. , Sun, J.‐H.

Changes of Heart Rate Variability during Methylphenidate Treatment in Attention-Deficit Hyperactivity Disorder Children: A 12-Week Prospective Study

Purpose The aim of this study was to clarify the relationship between the autonomic nervous system and attention deficit hyperactivity disorder (ADHD) rating scales and to evaluate the usefulness of heart rate variability (HRV) as a psychophysiological biomarker for ADHD. Materials and Methods Subjects were recruited from outpatients in the Department of Child and Adolescent Psychiatry at the Korea University Medical Center from August 2007 to December 2010. Subjects received methylphenidate. Time- and frequency-domain analyses of HRV, the Korean ADHD rating scale (K-ARS), and computerized ADHD diagnostic system were evaluated before treatment. After a 12-week period of medication administration, we repeated the HRV measurements and K-ARS rating. Results Eighty-six subjects were initially enrolled and 37 participants completed the 12-week treatment and HRV measurements subsequent to the treatment. Significant correlations were found between the K-ARS inattention score and some HRV parameters. All of the HRV parameters, except the standard deviations of the normal-to-normal interval, very low frequency, and low frequency to high frequency, showed a significant positive correlation between baseline and endpoint measures in completers. High frequency (HF) and the square root of the mean squared differences of successive normal-to-normal intervals (RMSSD), which are related to parasympathetic vagal tone, showed significant decreases from baseline to endpoint. Conclusion The HRV test was shown to be reproducible. The decrease in HF and RMSSD suggests that parasympathetic dominance in ADHD can be altered by methylphenidate treatment. It also shows the possibility that HRV parameters can be used as psychophysiological markers in the treatment of ADHD.
Latin Hypercube Approach to Estimate Uncertainty in Ground Water Vulnerability

A methodology is proposed to quantify prediction uncertainty associated with ground water vulnerability models that were developed through an approach that coupled multivariate logistic regression with a geographic information system (GIS). This method uses Latin hypercube sampling (LHS) to illustrate the propagation of input error and estimate uncertainty associated with the logistic regression predictions of ground water vulnerability. Central to the proposed method is the assumption that prediction uncertainty in ground water vulnerability models is a function of input error propagation from uncertainty in the estimated logistic regression model coefficients (model error) and the values of explanatory variables represented in the GIS (data error). Input probability distributions that represent both model and data error sources of uncertainty were simultaneously sampled using a Latin hypercube approach with logistic regression calculations of probability of elevated nonpoint source contaminants in ground water. The resulting probability distribution represents the prediction intervals and associated uncertainty of the ground water vulnerability predictions. The method is illustrated through a ground water vulnerability assessment of the High Plains regional aquifer. Results of the LHS simulations reveal significant prediction uncertainties that vary spatially across the regional aquifer. Additionally, the proposed method enables a spatial deconstruction of the prediction uncertainty that can lead to improved prediction of ground water vulnerability.
