    Hydroelectric power provides a cheap source of electricity with few carbon emissions. Yet, reservoirs are not operated sustainably, which we define as meeting societal needs for water and power while protecting long-term health of the river ecosystem. Reservoirs that generate hydropower are typically operated with the goal of maximizing energy revenue, while meeting other legal water requirements. Reservoir optimization schemes used in practice do not seek flow regimes that maximize aquatic ecosystem health. Here, we review optimization studies that considered environmental goals in one of three approaches. The first approach seeks flow regimes that maximize hydropower generation, while satisfying legal requirements, including environmental (or minimum) flows. Solutions from this approach are often used in practice to operate hydropower projects. In the second approach, flow releases from a dam are timed to meet water quality constraints on dissolved oxygen (DO), temperature and nutrients. In the third approach, flow releases are timed to improve the health of fish populations. We conclude by suggesting three steps for bringing multi-objective reservoir operation closer to the goal of ecological sustainability: (1) conduct research to identify which features of flow variation are essential for river health and to quantify these relationships, (2) develop valuation methods to assess the total value of river health and (3) develop optimal control softwares that combine water balance modelling with models that predict ecosystem responses to flow.

  15. Integrative network analysis reveals time-dependent molecular events underlying left ventricular remodeling in post-myocardial infarction patients.

    2017-02-03

    To elucidate the time-resolved molecular events underlying the LV remodeling (LVR) process, we developed a large-scale network model that integrates the 24 molecular variables (plasma proteins and non-coding RNAs) collected in the REVE-2 study at four time points (baseline, 1month, 3months and 1year) after MI. The REVE-2 network model was built by extending the set of REVE-2 variables with their mechanistic context based on known molecular interactions (1310 nodes and 8639 edges). Changes in the molecular variables between the group of patients with high LVR (>20%) and low LVR (<20%) were used to identify active network modules within the clusters associated with progression of LVR, enabling assessment of time-resolved molecular changes. Although the majority of molecular changes occur at the baseline, two network modules specifically show an increasing number of active molecules throughout the post-MI follow up: one involved in muscle filament sliding, containing the major troponin forms and tropomyosin proteins, and the other associated with extracellular matrix disassembly, including matrix metalloproteinases, tissue inhibitors of metalloproteinases and laminin proteins. For the first time, integrative network analysis of molecular variables collected in REVE-2 patients with known molecular interactions allows insight into time-dependent mechanisms associated with LVR following MI, linking specific processes with LV structure alteration. In addition, the REVE-2 network model provides a shortlist of prioritized putative novel biomarker candidates for detection of LVR after MI event associated with a high risk of heart failure and is a valuable resource for further hypothesis generation.

    2005-08-01

    At the 16th ESA Symposium on European Rockets and Balloons, two newly developed guidance and control systems by Saab Ericsson Space were presented: The S19D guidance and control system, which uses DS19 hardware to execute S19 type guidance and control. The GCS/DMARS guidance, navigation and control system, which is a modernisation of the GCS/RIINS. These two and the third recent system, the DS19, were developed as replacements for the analog S19 and the GCS/RIINS, both of which use very old technology. The design drivers or the DS19, the S19D and the GCS/DMARS are: User requirements. New technology with improved performance capability becoming available. Current technology becoming old and replacement parts hard to come by. This paper first lists some guidance related user requirements, and then discusses the performance that has been achieved in the various guidance systems, including the S19, for comparison. This is first done from a theoretical point of view and then by analyzing actual flight data. The ability of the systems to fulfil the user requirements is also discussed and finally, a look is taken into the future.

    X-ray irradiation with convergent chemicals such as nano-silver particles or sodium dichloroisocyanurate (NaDCC) has been used to control leaf blight on cut lilies. The oriental hybrid lily cultivars Siberia, Le Reve, and Sorbonne were irradiated five times by 200 Gy of X-rays in 2014. In 2015, Siberia and Sorbonne were irradiated three times by 150 Gy of X-rays. After artificial infection with Botrytis elliptica on the leaves and petals of cut lilies, this study used convergent chemical X-ray irradiation of 200 Gy or 150 Gy. Leaf and petal blight was measured in terms of incidence and severity at 8 days after infection using total 552 cuttings. Results indicate that the treatments of X-ray irradiation and NaDCC in 2014 and 2015 slightly decreased the severity of petal blight on Siberia and Sorbonne. However, the results were not significant and severity did not decrease as NaDCC concentration increased. Vase-life was observed separately after X-ray irradiation of 270 cut lilies in 2014 and 108 cut lilies in 2015. Chlorophyll content was not affected by either 200 Gy or 150 Gy of X-rays. The number of days of fully opened flowers at Siberia of 150 Gy and Le Revu of 200 Gy increased by 1-2 days. In addition, the relative fresh weights of the X-rayed flowers were 10% drier than the non-irradiated controls. Overall, leaf blight control by X-ray was inferior to the control by gamma rays, and petal color was bleached in Sorbonne and Le Reve cvs. by 150 Gy of X-rays.

    Saab Ericsson Space has continued its development of digital control systems, based on its previous experiences from the Maxus GCS and DS19. Two new systems now exist: The S19D guidance and control system, which uses DS19 hardware to execute S19 type guidance and control. The GCS/DMARS guidance, navigation and control system, which is a modernisation of the GCS/RIINS. The family of guidance systems provided by Saab Ericsson Space now includes: The analog S19 and the digital S19D for constant attitude guidance during the first part of a sounding rocket's powered flight. The DS19, that controls the attitude throughout the motor burn phase and navigates the vehicle to a pre-set impact point. The (Maxus) GCS with the same function as the DS19, but using thrust vector control via moveable nozzles instead of canard control. The SPINRAC and the RACS, providing exo-atmospheric impact point and attitude control by on-board thrusters.

  17. Increase in Mexican and Latin American scientific articles on irritable bowel syndrome.

    2015-01-01

    There is an implied perception that little scientific information on irritable bowel syndrome (IBS) comes out of Mexico and Latin America in the international medical literature, but the number and tendencies of articles from the region on IBS are not known. To determine the number and type of Mexican and Latin American articles on IBS published between 1990-2015. A systematic search of Medline was carried out employing the terms « Irritable Bowel Syndrome » or its abbreviation (IBS). Mexico and every other Latin American country were added to specify the search. The articles were selected if they were published in Mexico and/or the rest of Latin America, if they were international papers on IBS in the region, or if they were written by Mexican and/or Latin American authors. In addition, the articles were classified into the following categories: Reviews/Editorials/Letters to the Editor (REV/ED), Epidemiology/Quality of Life/Psychosocial Factors (EPI/QOL), Diagnostic (DX), Treatment (TX), and Translational/Pathophysiologic (TRANS) studies. A total of 66 articles from Mexico and 47 from Latin America were identified, but only 87.7 and 48.9%, respectively, fit the selection criteria. Category distribution was: EPI/QOL: 36.2%, REV/ED: 27.5%, TRANS: 18.8, TX: 10%, and DX: 7.5% and was similar between Mexico and Latin America (p=0.33). The year 2005 saw an increase in the number of articles in Mexico, with a peak in 2010. The figures for Latin American articles remained stable over the years, with a peak in 2012. A noticeable increase has been observed over the last decade in the research conducted on IBS in Mexico and Latin America. Even though the EPI/QOL studies predominate, the sophistication of research is reflected in the TRANS studies that are in third place of frequency. The information referred to herein demonstrates maturity in the field, making it possible to carry out consensuses based on local data. Copyright © 2015 Asociación Mexicana de

  18. Data modelling in corpus linguistics: how low may we go?

    PubMed

    van Velzen, Marjolein H; Nanetti, Luca; de Deyn, Peter P

    2014-06-01

    Corpus linguistics allows researchers to process millions of words. However, the more words we analyse, i.e., the more data we acquire, the more urgent the call for correct data interpretation becomes. In recent years, a number of studies saw the light attempting to profile some prolific authors' linguistic decline, linking this decline to pathological conditions such as Alzheimer's Disease (AD). However, in line with the nature of the (literary) work that was analysed, numbers alone do not suffice to 'tell the story'. The one and only objective of using statistical methods for the analysis of research data is to tell a story--what happened, when, and how. In the present study we describe a computerised but individualised approach to linguistic analysis--we propose a unifying approach, with firm grounds in Information Theory, that, independently from the specific parameter being investigated, guarantees to produce a robust model of the temporal dynamics of an author's linguistic richness over his or her lifetime. We applied this methodology to six renowned authors with an active writing life of four decades or more: Iris Murdoch, Gerard Reve, Hugo Claus, Agatha Christie, P.D. James, and Harry Mulisch. The first three were diagnosed with probable Alzheimer Disease, confirmed post-mortem for Iris Murdoch; this same condition was hypothesized for Agatha Christie. Our analysis reveals different evolutive patterns of lexical richness, in turn plausibly correlated with the authors' different conditions.

    Cerebrovascular Moyamoya disease (MMD) is a clinical entity characterized by stenotic or occlusive lesions around the terminal portions of the internal carotid arteries (ICA) and the formation of abnormal vascular networks at the base or convexity. This condition is sporadic, and there are no pathological explanations for this cause. A case with unilateral juvenile MMD is reported. A 13-year-old girl with sudden episode of left limbs weakness, accompanied by transient dysphasia and seizures attack, was admitted to our hospital for further investigation. Computed tomography scanning showed an area of localized brain swelling in the right capsular-thalamic region. Angiographic findings demonstra-ted unilateral involvement. Cerebral panangiography reve-aled a high grade stenosis of the right supraclinoid ICA and a peculiar network (moyamoya phenomenon) formed by dilated basal collateral perforating arteries and produced a cloudy image resembling "a puff of smoke". Left carotid angiogram showed a collateral circulation through the anterior communicant artery and apportioned to the right cerebral hemisphere. The vertebrobasilar system was normal. An ultrasoud Doppler study demonstrated a severely decreased blood flow gradient (0.1 l/min) through the right hypoplastic ICA, while the left common and the left ICA showed remarkable increased blood flow, partly due to abondant collateral vessels. Acquired, non-progressive vitiligo with areas of complete pigment loss appeared on flexor wrists, extensor distal extremities, superior eyelids and especially on joints regions (elbow, knee and small joints of the hands and fret). This association has not been reported previosly.

    Many mental health service users delay disclosing to employers or never do so due to previous experience of, or anticipation of discrimination. However, non-disclosure precludes requesting 'reasonable workplace adjustments'. Service users may experience conflicting needs and values in deciding whether to disclose. No evidence-based interventions exist to support this decision. A decision aid (CORAL, or COnceal or ReveAL) to support mental health service users in reaching disclosure decisions was developed and subjected to preliminary evaluation (n=15). The majority found the decision aid quick (60%) and relevant (60%) and would recommend it (80%). Eighty percent reported that they would definitely or probably use it in making disclosure decisions. Forty percent each were positive or neutral on its ease of use. Semi-structured interviews revealed a demand for more information on the legal implications of disclosure. The mean level of 'decisional conflict' regarding disclosure reduced from 52.0 to 35.5 and mean Stage of Decision-making Scale score from 4.6 to 4.3. The results suggest that the CORAL decision aid is feasible, relevant and valuable in supporting decisions about disclosing a mental illness to an employer. The decision aid could be deployed in routine care without significant resource implications. Crown Copyright © 2013. Published by Elsevier Ireland Ltd. All rights reserved.

    Many key components in commercial nuclear reactors are subject to neutron irradiation which modifies their mechanical properties. So far, the prediction of the in-service behavior and the lifetime of these components has required irradiations in so-called ';Experimental Test Reactors'. This predominantly empirical approach can now be supplemented by the development of physically based computer tools to simulate irradiation effects numerically. The devising of such tools, also called Virtual Test Reactors (VTRs), started in the framework of the REVE Project (REactor for Virtual Experiments). This project is a joint effort among Europe, the United States and Japan aimed at building VTRs able to simulate irradiation effects in pressure vessel steels and internal structures of LWRs. The European team has already built a first VTR, called RPV-1, devised for pressure vessel steels. Its inputs and outputs are similar to those of experimental irradiation programs carried out to assess the in-service behavior of reactor pressure vessels. RPV-1 is made of five codes and two databases which are linked up so as to receive, treat and/or convey data. A user friendly Python interface eases the running of the simulations and the visualization of the results. RPV-1 is sensitive to its inputs (neutron spectrum, temperature, …) and provides results in conformity with experimental ones. The iterative improvement of RPV-1 has been started by the comparison of simulation results with the database of the IVAR experimental program led by the University of California Santa Barbara. These first successes led 40 European organizations to start developing RPV-2, an advanced version of RPV-1, as well as INTERN-1, a VTR devised to simulate irradiation effects in stainless steels, in a large effort (the PERFECT project) supported by the European Commission in the framework of the 6th Framework Program.

    Background Decisions about whether to disclose mental health problems to employers are complex, with potential personal, employment and legal implications. Decision aids are evidence based tools, designed to help individuals make specific choices between treatment options. We previously developed a decision aid-Conceal Or ReveAL (CORAL)-to assist service users with decisions about disclosure to employers. As part of a mixed methods exploratory RCT, which demonstrated that the CORAL decision aid was effective in reducing decisional conflict, we aimed to explore its mechanism of action and to optimise the intervention for a future full scale trial. Methods In depth interviews were conducted with individuals receiving vocational support from a mental health trust and participating in the intervention arm of the pilot trial. Thematic analysis was conducted to identify the main themes relating to participants' perceptions of the CORAL decision aid. Results Thirteen participants were interviewed and five main themes were identified: sense of self and values; sense of control; anticipation of disclosure; experience of disclosure; and mechanism of action of the decision aid. Conclusions Data from our 13 participants suggest that the CORAL decision aid acts on several dimensions of decisional conflict: clarifying the pros and cons of different choices; increasing knowledge; structuring the decision making process; and clarifying needs and values. The current study indicated that it would be most effective when delivered by a professional well versed in employment and mental health matters such as a vocational adviser. The need for employers and policymakers to reduce the negative impact of disclosure is also highlighted.

    The aim of this study was to evaluate the reproducibility of anatomical landmarks and the accuracy of different cone-beam CTs (CBCTs/DVTs) and a multislice spiral CT (MSCT) scanner. A human, fresh-frozen cadaver head was scanned with four CBCTs (Accuitomo 3D, 3D eXam, Pax Reve 3D, Pax Zenith 3D) and one MSCT (SOMATOM Sensation 64) scanner. The three-dimensional (3D) reconstruction of the volume data sets and location of the anthropometric landmarks (n=11), together with linear (n=5) and angular (n=1) measurements were carried out by three examiners using the program VoXim® 6.1. The measurements were taken twice at a 14-day interval. Descriptive analyses were made and the standard deviations were used to compare differences in the accuracy of landmark identification. The descriptive statistics showed distinct differences in the reference points in the three axes of the coordinate system. Because of anatomical and morphological factors, the pogonion and gnathion reference points displayed higher standard deviations when set on the transverse plane (SD(CBCT) Pog: 0.66-1.57 mm; SD(MSCT) Pog: 0.14-1.09 mm; SD(CBCT) Gn: 1.05-1.77 mm; SD(MSCT) Gn: 0.20-0.85 mm), thus showing less accuracy. However, standard deviations on the sagittal and vertical planes were smaller. Genion, anterior nasal spine and infradentale had very low standard deviations on all three planes. The distance (Mfl-Mfr) and angle (Krl-Krr-Ge) revealed significantly smaller standard deviations in the MSCT (SD(CBCT) Krl-Krr-Ge: 0.51-0.75 mm; SD(MSCT) Krl-Krr-Ge: 0.22 mm). The CBCT devices evaluated in this study are suitable for taking exact 3D measurements of anatomical structures and meet all requirements for 3D cephalometric analysis.
