Crustal velocity structure across the Orphan Basin and Orphan Knoll to the continent–ocean transition, offshore Newfoundland, Canada

Orphan Basin, a massive deepwater rifted basin off the northeastern coast of Newfoundland, was one of the targets of the 2009 SIGNAL (Seismic Investigations off Greenland, Newfoundland and Labrador) experiment to collect refraction/wide-angle reflection (RWAR) data from the Bonavista Platform, through the Orphan Basin, to the Orphan Knoll, and beyond into oceanic crust. Both the data from an earlier RWAR acquisition and the new data were jointly analysed in order to improve on the earlier velocity model and extend its coverage landward and seaward. The resulting velocity model is characterized by an 8–9-km-thick sedimentary package immediately outboard of the Bonavista Platform, which thins toward the Orphan Knoll and beyond. The shallowest modelled sedimentary layer, interpreted as Paleocene and younger post-rift sediments, does not show significant thickness variations and velocities do not exceed 3.3 km s–1. The second modelled sedimentary layer with laterally variable velocities ranging from 2.3 to 5.3 km s–1, interpreted as Late Cretaceous post-rift sediments, is thickest over an interpreted failed rift. The deepest modelled sedimentary layer consists of laterally variable velocities that do not exceed 5.9 km s–1 and is interpreted as possibly Jurassic to Early Cretaceous syn-rift sediments. The crust beneath the Bonavista Platform is subdivided into an upper (5.4–5.9 km s–1), middle (5.9–6.4 km s–1) and lower crust (6.4–6.9 km s–1). The middle crust is modelled as disappearing beneath the seaward limit of the Bonavista Platform at an interpreted failed rift, only to re-appear 100 km further seaward beneath the central Orphan Basin and extend to the seaward limit of the Orphan Knoll, beyond which the crust can be modelled by just an upper (5.0–6.7 km s–1) and a lower (6.7–7.0 km s–1) crustal layer. Towards land, for the first 450 km of the model, velocities generally follow the globally averaged velocity trend for rifted continental crust, albeit with slightly elevated velocities suggestive of magmatic contributions. At the failed rift, within the continental domain, hyperextended crust is modelled, overlying a limited zone of serpentinized mantle. Seaward of Orphan Knoll, the interpretation for the velocity structure is less definitive but an 80-km-wide continent–ocean transition zone consisting of either transitional embryonic oceanic crust or thinned continental crust overlying serpentinized mantle is proposed. Upper mantle velocities as low as 7.7 km s–1 are modelled beneath the interpreted failed continental rift as well as beneath the continent–ocean transition zone, while the rest of the crustal model is underlain by typical mantle velocities of 8 km s–1. Analysis of extension and thinning factors based on the velocity model reveal that the failed rift experienced hyperextension and should have achieved full crustal embrittlement, consistent with localized mantle serpentinization.
Surgical treatment of moderate and severe hallux valgus: 30 cases undergoing surgery using the percutaneous Chevron technique

Objective: To evaluate the radiographic parameter correction and clinical improvement of moderate and severe hallux valgus deformities treated by percutaneous Chevron osteotomy. Methods: Twenty-six patients (30 feet) underwent surgery. The following were measured preoperatively and postoperatively: hallux metatarsophalangeal (MTP) angle, intermetatarsal angle between the 1st and 2nd metatarsals (IMA), distal metatarsal joint angle (DMJA) and pre- and postoperative AOFAS scores with a minimum of 6 months of follow-up. Results: The mean patient age was 52.3 years. Preoperatively, the mean AOFAS score was 45.6, which rose to 90.3 after the procedure, showing a statistically significant improvement. The preoperative mean MTP, IMA and DMJA angles were 29.7°, 14.2° and 14.2°, respectively, and the postoperative values were 12.8°, 8.2° and 11.1°, respectively. The improvements in MTP and IMA angles were also statistically significant. There were no losses in angular parameters or worsening of AOFAS scores during follow-up. Conclusion: The percutaneous Chevron surgical technique proved to be safe and effective for the correction of moderate and severe hallux valgus cases and achieved significant improvements in clinical and radiographic parameters and low rates of postoperative complications. Level of Evidence III; Retrospective Comparative Study.
Comparative study of anterior support ankle foot orthosis and posterior ankle foot orthosis in foot drop patients

Background: Anterior Support Ankle Foot Orthosis (A-AFO) is a fairly recent approach. There is dearth of studies relating to comparison of metabolic efficiency of A-AFO and P-AFO. Objective was to study the efficacy of A-AFO compared to P-AFO in foot drop patients, using gait and metabolic analysis. Methods: It was a cross over study, included foot drop patients who could walk with/ without orthosis. Patients having spasticity more than grade 2 (Modified Ashworth Scale) were excluded. The metabolic parameters measured were volume of Oxygen consumed at Standard Temperature and Pressure in l/min (VO 2 ), Dry in l/min, Rate of Oxygen consumption (MET), Volume of Carbon dioxide produced in litre/min (VCO 2 ). Along with various gait parameters, questionnaire about patient’s preference after 4 weeks was also incorporated. Results: A-AFO was significantly better than P-AFO in terms of VO 2 and VCO 2 (p value = 0.02 and 0.009 respectively) as well as in terms of subjective preference. Conclusions: A-AFO is comparable to P-AFO in terms of energy efficiency, gait parameters and subjective preference, hence should also be prescribed.
A cm-scale, low wind velocity and 250°C-compliant airflow-driven harvester for aeronautic applications

This paper reports the design, fabrication, and testing of a centimeter-scale (Ørotor=35mm), 250°C-compliant microturbine for aeronautic applications. Dedicated to low-speed air flows (≈3 m/s and down to 2 m/s), this device is the first flow-driven harvester withstanding such high temperatures and high vibration levels (107 cycles at 20G). Furthermore, the proposed harvester exhibits the highest output power per unit cross sectional area compared to prior art in the cm-scale and low velocity ranges.
Closure of patent foramen ovale for secondary prevention of cerebrovascular events

Stroke is the most debilitating cardiovascular event. It has a variety of causes that may be present simultaneously. In young or otherwise healthy people a patent foramen ovale (PFO) is increasingly searched for. In stroke of the elderly atherosclerosis and atrial fi brillation are in the foreground but the PFO should not be ignored. The risk of a PFO related stroke over time is controversial and so is its prevention by PFO closure. Percutaneous PFO closure is a minimally invasive procedure which can be performed with high success and low morbidity. We review the rationale for PFO closure for secondary prevention of embolic events.

Foi considerado Anemia da Doenca Cronica quando houve diminuicao dos niveis sericos de ferro (< 37 μg/dl para mulheres e 100μg/l) e diminuicao do indice de saturacao da transferrina (<16%). - na presenca de dados clinicos, laboratoriais ou endoscopicos de inflamacao intestinal e Anemia Mista quando houve diminuicao dos niveis sericos de ferro (< 37 μg/dl para mulheres e < de 59 μg/dl para homens) e ferritina entre 30 e 100μg/l. As anemias foram classificadas em hiporregenerativas quando a contagem absoluta de reticulocitos estava abaixo de 50000 e normoproliferativas ou normorregenerativas quando a contagem absoluta de reticulocitos estava acima de 100000/mm³.
An overview of the quality assurance and quality control of magnetic resonance imaging data for the Ontario Neurodegenerative Disease Research Initiative (ONDRI): pipeline development and neuroinformatics

Large scale research studies combining magnetic resonance imaging data generated at multiple sites on multiple vendor platforms are becoming more commonplace. The Ontario Neurodegenerative Disease Research Initiative (ONDRI - http://ondri.ca/), a project funded by the Ontario Brain Institute (OBI), is a recently established province-wide natural history study, which has recruited more than 500 participants from neurodegenerative disease groups including amyotrophic lateral sclerosis, fronto-temporal dementia, Parkinson’s disease, Alzheimer’s disease, mild cognitive impairment, and cerebrovascular disease (previously referred to as the vascular cognitive impairment cohort). Because of its multi-site nature, all captured data must be standardized and meet minimum quality standards to reduce variability. The goal of the ONDRI imaging platform is to maximize data quality by implementing vendor-specific harmonized MR imaging protocols (consistent with the Canadi-an Dementia Imaging Protocol - http://www.cdip-pcid.ca/), monitoring protocol adherence, qualitatively assessing image quality, measuring signal-to-noise and contrast-to-noise, monitoring system stability, and applying corrections based on the analysis of images from two different phantoms regularly acquired at each site. To maximize image quality, this work describes the use of various automatic pipelines and manual assessment steps, integrated within an established informatics and databasing platform, the Stroke Patient Recovery Research Database (SPReD) built on the Extensible Neuroimaging Archive Toolkit (XNAT), and contained within the Brain-CODE (Centre for Ontario Data Exploration) framework. The purpose of the current paper is to describe the steps undertaken by ONDRI to achieve this high standard of data integrity. Data have been successfully collected for the past 4 years with the pipelines and assessments identifying deviations, allowing for timely interventions and assessment of image quality.
Computer simulation of local microstructure and dynamics in aluminum-silicate melt

We have investigated the aluminum-silicate melt used as a simple case for many-component network-forming liquids. Based on the calculation of T–O subnets, T–O bonds (T is Si or Al) and commuting linkages, a systematic analysis is carried out to clarifying specific features of microstructure and dynamics. The simulation reveals a strong correlation between the mean square displacements and number of T–O bonds which remain unbroken during the simulation time. The model contains T–O subnets which behave like large molecules. We also find that most mobile and immobile atoms tend to gather in large clusters, the number of which slightly changes during the simulation time. In contrast, the atoms randomly taken from the system form numerous small clusters. The simulation result clearly demonstrates the micro-segregation and strong heterogeneity in dynamics and structure. In particular, the breaking and forming of T–O bonds (the replacing of T–O bonds by new ones) happen non-uniformly through the network structure. The atoms do not move in random directions, but they prefer to displace together by groups.
The combination of term relations analysis and weighted frequent itemset model for multidocument summarization

Nowadays, it is necessary that users have access to information in a concise form without losing any critical information. Document summarization is an automatic process of generating a short form from a document. In itemset‐based document summarization, the weights of all terms are considered the same. In this paper, a new approach is proposed for multidocument summarization based on weighted patterns and term association measures. In the present study, the weights of the terms are not equal in the context and are computed based on weighted frequent itemset mining. Indeed, the proposed method enriches frequent itemset mining by weighting the terms in the corpus. In addition, the relationships among the terms in the corpus have been considered using term association measures. Also, the statistical features such as sentence length and sentence position have been modified and matched to generate a summary based on the greedy method. Based on the results of the DUC 2002 and DUC 2004 datasets obtained by the ROUGE toolkit, the proposed approach can outperform the state‐of‐the‐art approaches significantly.
Investigating Attentional Allocation With Eye Tracking During Category Learning in People With Aphasia

Studies have identified deficits in attention in individuals with aphasia in language and nonlanguage tasks. Attention may play a role in the construction and use of language, as well as in learning and the process of rehabilitation, yet the role of attention on rehabilitation is not fully understood. To improve the understanding of attention and learning in aphasia, this study replicated an experiment that utilized category learning to examine attentional allocation. Ten individuals with aphasia subsequent to left hemisphere stroke and 20 age-matched controls completed a computer-based category learning task while eye gaze data were collected using an eye tracker. Stimulus items comprised 4 features that differed in the reliability with which they predicted category membership (referred to as their diagnosticity). In this study, no differences were observed between individuals with aphasia and control participants on behavioral measures of accuracy and response time, though accuracies overall were lower than those of prior studies examining this task in young adults. Eye gaze data demonstrated that over the course of training, controls and individuals with aphasia learned to reduce the number of looks to the feature of lowest diagnosticity, suggestive of optimized attentional allocation. Eye gaze patterns, however, did not show increased looking or look times to all features of highest diagnosticity, which has been seen in young adults. Older adults and individuals with aphasia may benefit from additional processing time or additional trials during category learning to optimize attention and behavioral accuracy. Findings are relevant to consider in clinical settings where visual stimuli are presented as instructional, supporting, and/or compensatory tools.

OPTIMIZATION OF ATTRIBUTE SELECTION MODEL USING BIO-INSPIRED ALGORITHMS

Attribute selection which is also known as feature selection is an essential process that is relevant to predictive analysis. To date, various feature selection algorithms have been introduced, nevertheless they all work independently. Hence, reducing the consistency of the accuracy rate. The aim of this paper is to investigate the use of bio-inspired search algorithms in producing optimal attribute set. This is achieved in two stages; 1) create attribute selection models by combining search method and feature selection algorithms, and 2) determine an optimized attribute set by employing bio-inspired algorithms. Classification performance of the produced attribute set is analyzed based on accuracy and number of selected attributes. Experimental results conducted on six (6) public real datasets reveal that the feature selection model with the implementation of bio-inspired search algorithm consistently performs good classification (i.e higher accuracy with fewer numbers of attributes) on the selected data set. Such a finding indicates that bio-inspired algorithms can contribute in identifying the few most important features to be used in data mining model construction.
Appropriate uses of anthropometric indices in children. A report based on an ACC / SCN workshop.

This state-of-the-art UN discussion paper explores the need for greater clarity on the use and interpretation of anthropometric measurements in children in developing countries. The discussion is based on a workshop convened in Geneva in 1989 by the UN Subcommittee on Nutrition. Its goal was a reaffirmation of the utility of appropriately applied anthropometric measures and a conciliation of salient debates. Although anthropometry cannot identify the causes of growth failure is the best general proxy for constraints to human welfare in the poorest sectors of society and a feasible predictor of subsequent health. This report focuses on the use of length and weight measures for individual one-time screening ongoing individual growth monitoring one-time population assessment and nutritional surveillance at the population level over time. An approach is adopted that begins with identification of decisions to be made within the area of application. From this information requirements are specified taking into account the nature specificity and sensitivity of measures available.
Proteomics Analysis of Differential Expression of Lung Proteins in Response to Highly Pathogenic Avian Influenza Virus Infection in Chicken

Elucidation of molecular pathogenesis underlying virus-host interaction is important for the development of new diagnostic and therapeutic strategies against highly pathogenic avian influenza (HPAI) infection in chicken. However, chicken HPAI viral pathogenesis is not completely understood. To elucidate the intracellular signaling pathways and critical host proteins associated with influenza pathogenesis, we characterized the lung proteome of chicken infected with HPAI H5N1 virus (A/duck/India/02CA10/2011/Agartala). The chicken mass spectra data sets comprised1, 47, 451 MS scans and 19, 917 MS/MS scans. At local FDR 5% level, we identified total 3313 chicken proteins with presence of at least one unique peptide. At 12 hrs, 247 proteins are downregulated while 1754 proteins are downregulated at 48 hrs indicating that the host has succumbed to infection. There is expression of proteins of the predominant signaling pathways, such as TLR, RLR, NLR and JAK-STAT signaling. Activation of these pathways is associated with cytokine storm effect and thus may be the cause of severity of HPAI H5N1 infection in chicken. Further we identified proteins like MyD88, IKBKB, IRAK4, RELA, and MAVS involved in the critical signaling pathways and some other novel proteins(HNF4A, ELAVL1, FN1, COPS5, CUL1, BRCA1 and FYN) as main hub proteins that might play important roles in influenza pathogenesis in chicken. Taken together, we characterized the signaling pathways and the proteomic determinants responsible for disease pathogenesis in chicken infected with HPAI H5N1 virus.
Zonal Inertia Constrained Generator Dispatch Considering Load Frequency Relief

Synchronous generators are operating for less time than before or being decommissioned in the National Electricity Market (NEM) of Australia, due to the proliferation of asynchronous wind and solar generation. Sub-networks of the NEM will face inertia shortages in the near future. This paper develops a formulation of zonal inertia constrained generator dispatch for power systems with a diversified generator portfolio including synchronous generators, synchronous condensers, inverter-interfaced generators and energy storages. Zonal inertia constraints are formulated in unit commitment and optimal power flow to limit the rate of change of frequency (RoCoF) in the event of network separation. Load frequency relief is also considered to reduce the ramp rate requirement of primary reserve. The proposed formulation can reduce the average cost of primary reserve and maintain zonal inertia adequacy to constrain RoCoF in case of the trip of the interconnector(s).
E-Government Project Evaluation Based on the Theory of Life-cycle Management

—Conducting an e-government project evaluation is an important way to circumvent risks and improve the success rate of the e-government project. At present, China’s e-government project evaluation mainly focuses on post-evaluation, which is performance evaluation but lacks the life-cycle evaluation, resulting in a high project failure rate and low return on investment. This paper is mainly talking about the construction of e-government projects evaluation based on the life-cycle theory. Dividing e-government projects construction into four stages: project preparation, project bidding, project implementation and project operation and maintenance. Starting from the four core stages of the e-government projects, a new closed-loop evaluation index is put forward to make the e-government project evaluation more convincing and scientific.
