Mazères, Benoît and Desgranges, Clara and Toffolon-Masclet, Caroline and Monceau, Daniel Modeling Two- and Three-Stage Oxygen Tracer Experiments during High-Temperature Oxidation of Metals with a High Oxygen

The numerical tool EKINOX-Zr has been upgraded to simulate oxygen tracer experiments during the high-temperature oxidation of a metal with a high oxygen solubility limit. The penetration of O tracer is calculated during the dynamic evolution of the ZrO2-x/aZr(O)/bzr system. The numerical approach allows to explicitly take into account the variation of the tracer diffusion coefficient through the oxide scale as a function of the vacancy concentration. A classical twostages O2/ O2 tracer experiment has been simulated. It is shown that a classical fitting procedure on the O concentration profile obtained for short-time experiments leads to the identification of the oxygen chemical diffusion coefficient. The second type of tracer experiment is proposed using a three-stages O2/ O2/ O2 & Daniel Monceau daniel.monceau@ensiacet.fr Benoı̂t Mazères benoit.mazeres@gpseo.fr Clara Desgranges clara.desgranges@safrangroup.com Caroline Toffolon-Masclet caroline.toffolon@cea.fr 1 CIRIMAT, Université de Toulouse, CNRS, INPT, UPS, ENSIACET, 4 Allée Emile Monso, BP44362, 31030 Toulouse Cedex 4, France 2 DEN-Service de la Corrosion et du Comportement des Matériaux dans leur Environnement, CEA, Université Paris-Saclay, 91191 Gif-sur-Yvette, France 3 DEN-Service de Recherches Métallurgiques Appliquées, CEA, Université Paris-Saclay, 91191 Gif-sur-Yvette, France 4 Present Address: SAFRAN Tech, rue des Jeunes Bois, 78772 Magny-les-Hameaux, France 5 Present Address: CU GPS&O, Immeuble Autonéum, Rue des Chevries, 78410 Aubergenville, France https://doi.org/10.1007/s11085-017-9816-3
Electronic properties of bulk -Al2O3

The electronic structure of bulk -alumina is investigated using Density Functional Theory. Recent theoretical structures, including occupation of nonspinel positions, are used as starting point for energy minimization, allowing for relaxation of the cell shape and the ionic positions. A comparison of simulated diffraction patterns of the present and recent theoretical and experimental structural models is presented. The electronic structure is described in terms of band structure, density of states, charge density, electron localization function, and ionic charges. The valence band density of states of -alumina is similar to and -alumina, although a smaller bandgap is found. It is shown that -alumina ionicity is similar to other alumina phases, with a high localization of the electrons at oxygen atoms. The smaller bandgap of -alumina is attributed to the structural disorder.
PSBP-SVM: A Machine Learning-Based Computational Identifier for Predicting Polystyrene Binding Peptides

Polystyrene binding peptides (PSBPs) play a key role in the immobilization process. The correct identification of PSBPs is the first step of all related works. In this paper, we proposed a novel support vector machine-based bioinformatic identification model. This model contains four machine learning steps, including feature extraction, feature selection, model training and optimization. In a five-fold cross validation test, this model achieves 90.38, 84.62, 87.50, and 0.90% SN, SP, ACC, and AUC, respectively. The performance of this model outperforms the state-of-the-art identifier in terms of the SN and ACC with a smaller feature set. Furthermore, we constructed a web server that includes the proposed model, which is freely accessible at http://server.malab. cn/PSBP-SVM/index.jsp.
Low Cholesterol Level Linked to Reduced Semantic Fluency Performance and Reduced Gray Matter Volume in the Medial Temporal Lobe

Hyperlipidemia has been proposed as a risk factor of dementia and cognitive decline. However, the findings of the relationship between cholesterol level and cognitive/brain function have been inconsistent. Here, using a well-controlled sample from the Parkinson’s Progression Markers Initiative (PPMI), we investigated the probable non-linear relationship between plasma total cholesterol (TC) level, gray matter volume (GMv), and cognitive performance in 117 non-demented subjects (mean age, 61.5 ± 8.9 years), including 67 Parkinson’s disease (PD) patients and 50 demographically matched controls. A quadratic relationship between semantic fluency (SF) performance and TC levels was identified. Within the subjects with a desirable TC level (TC < 200 mg/dl), low TC (lTC) levels were associated with reduced SF performance, as well as reduced GMv in three medial temporal regions [including bilateral anterior hippocampus (HIP)]. In contrast, no significant relationship between TC and cognition performance/GMv was found in individuals with a high cholesterol level (i.e., TC ≥ 200 mg/dl). Further region of interest (ROI)-based analysis showed that individuals with TC levels ranging from 100 to 160 mg/dl had the lowest GMv in the medial temporal regions. These findings suggest that low-normal TC level may be associated with reduced cognitive function and brain atrophy in regions implicated in neurodegenerative diseases, adding to a growing body of literature supporting a probable non-linear relationship between cholesterol level and brain health. However, this finding needs to be verified with other large public cohort data that do not include PD patients.
Biped Robots With Compliant Joints for Walking and Running Performance Growing

This paper deals with the problem of compliance in biped robots locomotion. After a first literature review, we designed and simulated a 3D virtual model of a biped robot conceived with the same link dimensions (and weights) of a standard man. In all simulation, the same input to the robot actuators are proposed, modifying only the compliance of the attached links. We first validated the model and then compared results increasing and reducing compliance on hip, knee and ankle joints. The very good results underline how the robot performances may be increased including the compliant element in the knee. In particular, we noted how including a proper value of the compliance in the knee, power and torque of the actuators may be reduced increasing robot speed.
Efecto Afidicida de una Fracción de Flavonoides de Dodonaea viscosa1 contra Melanaphis sacchari2

Resumen. El objetivo principal de este estudio fue identificar el compuesto mayoritario de una fracción (F3) de hojas de Dodonaea viscosa con actividad afidicida contra Melanaphis sacchari. El 3-O-rutinósido de quercetina (rutina) fue aislado de F3 por técnicas cromatográficas convencionales e identificado por resonancia magnética nuclear y análisis de cromatografía liquida de alta resolución (HPLC). La fracción F3 obtenida de un extracto metanólico de D. viscosa (DvEM), exhibió una actividad afidicida del 70% frente a M. sacchari en una concentración de 10,000 ppm a las 72 horas en dieta artificial. El insecticida imidacloprid produjo 100% de mortalidad de los áfidos, mientras que la mortalidad en el control fue 5%. Pruebas fitoquímicas clásicas comprobaron la presencia de alcaloides, flavonoides, taninos, cumarinas, antracenos, saponinas, triterpenos, y/o esteroides, en DvEM, para identificar los grupos de compuestos presentes y así llevar a cabo la estrategia de separación química. El perfil químico de DvEM realizado por HPLC indica que la fracción F3 está constituida por flavonoides, destacando la presencia de rutina. Este flavonol aislado de F3 fue caracterizado por RMN de 1H y 13C. Los resultados demostraron que este tipo de flavonoides mayoritarios en DvEM pueden ser considerados como una alternativa para el desarrollo de nuevos insecticidas, constituyendo una opción ante los productos químicos tóxicos que actualmente se encuentran en el mercado.

Sexual Activity at 1 Year after Acetabular Fracture

Financial support: None. Conflict of interests: None. Purpose: Change in sexual activity after acetabular fracture has not been elucidated to date. Hence, the purpose of this study was to reveal: (1) how acetabular fracture affects the status of sexual activity; (2) how acetabular fracture affects patient satisfaction about sexual activity; and (3) what are the concerns of patients regarding sexual activity. Materials and Methods: Between January 2014 and December 2014, a self-reported questionnaire was conducted with patients who had been sexually active before the treatment for acetabular fracture. Out of the nineteen patients who participated in the questionnaire, twelve men and three women were included for final analysis; patients who were treated conservatively were excluded. Results: All patients had hip pain (mean visual analogue scale score, 2.9; range, 1-7) at 1 year after the trauma. Fourteen patients (93.3%, 14/15) resumed sexual activity within 1 year (mean, 3.9 months; range, 2-6 months). After excluding one patient who did not recover to allow sexual activity, the frequency of sex was decreased in 11 patients (78.6%, 11/14). Sexual satisfaction was decreased in seven patients (46.7%, 7/15). Old age was associated with decreased sexual satisfaction. Conclusion: Half of the patients showed a decreased satisfaction from sexual activity after acetabular fracture, with hip pain being the most common problem. Although our study was a small, single-center study, it provides information regarding sexual activity of patients after acetabular fracture.
Trend of home or hospital delivery and child birth among Muslim women of Biratnagar, Nepal

Background: Maternal morbidity and mortality remains one of the biggest public health challenges in Nepal. This paper explores the trend of home or hospital delivery and child birth in certain ethnic group. The illiteracy women’s low socio economic status in the society, lack of access and difficult geographical rugged terrain are major reasons for not delivering children in health institutions in Nepal.Objective: To find out the trend of hospital or home delivery among Muslim women of Biratnagar city.Methods: Cross-sectional study was conducted among 200 Muslim women of ward 7 of Biratnagar municipality. They were interviewed to assess their health seeking trend of home or hospital delivery and child birth along with factors associated with the use of health services. Information's on usages of health services, education level, family structure, and occupational status information were also collected using a pre-tested and structured questionnaire.Results: The overall institutional delivery in the study population was 24.5%. Illiteracy, low socio-economic status, and poverty in women are the major challenging features of not delivering babies in health institutions.Conclusion: Only one fourth of the women of the study population had hospital/health institutional delivery. Hospital deliveries were seen among the educated women with many antenatal visits. Therefore female education must be encouraged in this community. Health Renaissance 2015;13 (1): 68-76

Modeling and Targeting Alzheimer’s Disease With Organoids

Human neurodegenerative diseases, such as Alzheimer’s disease (AD), are not easily modeled in vitro due to the inaccessibility of brain tissue and the level of complexity required by existing cell culture systems. Three-dimensional (3D) brain organoid systems generated from human pluripotent stem cells (hPSCs) have demonstrated considerable potential in recapitulating key features of AD pathophysiology, such as amyloid plaque- and neurofibrillary tangle-like structures. A number of AD brain organoid models have also been used as platforms to assess the efficacy of pharmacological agents in disease progression. However, despite the fact that stem cell-derived brain organoids mimic early aspects of brain development, they fail to model complex cell-cell interactions pertaining to different regions of the human brain and aspects of natural processes such as cell differentiation and aging. Here, we review current advances and limitations accompanying several hPSC-derived organoid methodologies, as well as recent attempts to utilize them as therapeutic platforms. We additionally discuss comparative benefits and disadvantages of the various hPSC-derived organoid generation protocols and differentiation strategies. Lastly, we provide a comparison of hPSC-derived organoids to primary tissue-derived organoids, examining the future potential and advantages of both systems in modeling neurodegenerative disorders, especially AD.
Frontier Detection and Exploration using Monocular SLAM

In this thesis, we propose a novel planning technique for monocular camera based Simultaneous Localization and Mapping(VSLAM) and fast Frontier detection method for autonomous explorartion in an indoor evvironment. In VSLAM, the objective is to estimate the trajectory of camera and simultaneously identify key 3D feature points and build a map, using camera as a depth sensor. Unlike a laser range ﬁnder(LRF) based SLAM, VSLAM is known to be erroneous when camera motion includes an in-place rotation or feature displacement is large for successive frames. We propose a motion planning framework which combines motion primitives based planning and trajectory optimization approach to generate trajectories which exactly connects an initial and ﬁnal state and also ensures that the change in camera’s ﬁeld of view between subsequent instances is less than some speciﬁed threshold. As a consequence of this motion planning framework we are able to automate SLAM and generate automated monocular SLAM maps of an indoor lab area. We also show when the robot follows the path of a generic planner, PTAM trajectory breaks more often than when it executes the path computed by the proposed planner. This performance improvement is further utilised to develop an autonomous vision based exploration system.
StARe: Gaze-Assisted Face-to-Face Communication in Augmented Reality

This research explores the use of eye-tracking during Augmented Reality (AR) - supported conversations. In this scenario, users can obtain information that supports the conversation, without augmentations distracting the actual conversation.We propose using gaze that allows users to gradually reveal information on demand. Information is indicated around user’s head, which becomes fully visible when other’s visual attention explicitly falls upon the area. We describe the design of such an AR UI and present an evaluation of the feasibility of the concept. Results show that despite gaze inaccuracies, users were positive about augmenting their conversations with contextual information and gaze interactivity. We provide insights into the trade-offs between focusing on the task at hand (i.e., the conversation), and consuming AR information. These findings are useful for future use cases of eye based AR interactions by contributing to a better understanding of the intricate balance between informative AR and information overload.

Spatial Environmental and Resource Economics

Although the spatial dimension is embedded in the vast majority of issues studied by environmental and resource economics, its incorporation into economic models - especially in the form of explicit introduction of a spatial transport mechanism - is not widespread. As a result, important aspects of these issues may not be accounted for, which could lead to regulatory inefficiencies. In this paper, the major spatial transport mechanisms are discussed, along with the way in which they can be incorporated into forward-looking optimizing economic models. Furthermore, an extension of Pontryagin's maximum principle under spatial dynamics is provided and the emergence of spatial pattern formation through optimal Turing instability is explained. A number of examples of the use of spatial dynamics illustrate why space matters in environmental and resource economics. Moreover, the differentiation of policy when spatial transport mechanisms are taken into account is presented. The tools presented in the paper, along with their applications, provide a path for future research in environmental and resource economics in which the underlying spatial dimension - which is very real - is fully taken into account.
CARP: A Data Communication Mechanism for Multi-core Mixed-Criticality Systems

We present CARP, a predictable and high-performance data communication mechanism for multi-core mixed-criticality systems (MCS). CARP is realized as a hardware cache coherence protocol that enables communication between critical and non-critical tasks while ensuring that non-critical tasks do not interfere with the safety requirements of critical tasks. The key novelty of CARP is that it is criticality-aware, and hence, handles communication patterns between critical and non-critical tasks appropriately. We derive the analytical worst-case latency bounds for requests using CARP and note that the observed per-request latencies are within the analytical worst-case latency bounds. We compare CARP against prior data communication mechanisms using synthetic and SPLASH-2 benchmarks. Our evaluation shows that CARP improves the average-case performance of MCS compared to prior data communication mechanisms, while maintaining the safety requirements of critical tasks.
Promises to keep. The toll of unintended pregnancies on womens lives in the developing world.

Nearly 200 million women become pregnant around the world each year. The United Nations estimates that one-third of these pregnancies are unintended and unwanted. Of these many result in the death of the mother. How many women would be alive today if contraceptives and family planning services had been available to prevent these pregnancies? Thanks to a grant from the David and Lucile Packard Foundation the Global Health Council has compiled a statistical analysis designed to detail the cost in women’s lives and health as a result of unintended pregnancy. At the 1994 International Conference on Population and Development (ICPD) in Cairo 179 nations pledged to improve the health of the world’s women. How well has the world done in meeting this commitment? While the goal of this analysis is to provide an accurate metric for assessing the consequences of unintended pregnancy it should not be forgotten that every statistic included represents the life of a woman or girl a wife a mother a daughter or a sister. These statistics and the lives they represent shed light on a hidden and intransigent epidemic of premature death and disability that plays itself out in thousands of communities every minute of every day. The women whose lives are represented in the analysis detailed in this report and whose stories appear throughout this document were victims of a twofold tragedy: they wanted to avoid pregnancy and they wanted to live. It is a somber reflection of the world’s priorities that they were unable to do either. (excerpt)
The Economics of Sustainable Development

In this introductory chapter we aspire to offer a comprehensive yet complete roadmap of the concept and content of the much used but not quite appropriately perceived term of sustainability economics. Interestingly, there is not a formal and universally accepted definition as the field is considered as a relative science and thus requires an interdisciplinary approach to be studied. However, through indicative yet recent literature we offer an insight on the state of the art in order to relate with its core meaning. A historical background is also outlined as understanding the foundations is crucial. Elements of Economic Theory serve as means to bridge the past and current trends on how theories have evolved to understand what is necessary to achieve not only economic growth in numbers but also to ensure well-being and prosperity for the current and future generations.
