La contraception d'urgence chez les adolescents en Suisse: une étude sur la sexualité des 16-20 ans
Creators: name: Ottesen, Sandrine
Publisher: name: Unknown
Year: 0

description: Objectifs: Faire le point sur les connaissances concernant la contraception post-coïtale (CPC) et son utilisation par les adolescentes, et réunir les recommandations utiles aux médecins prescripteurs. Matériel et méthodes: La revue de littérature concernant la CPC et les résultats d'une enquête concernant les comportements sexuels des adolescents de 16-20 ans en Suisse sont utilisés. Résultats: Plusieurs méthodes peuvent être utilisées incluant les oestroprogestatifs et les progestatifs seuls. C'est surtout à l'occasion de rupture de préservatif, d'oubli de pilule ou d'absence de contraception que la CPC peut être utile. Les adolescents sexuellement actifs semblent connaître l'existence de la CPC et 20% des jeunes filles y ont eu recours en Suisse. Mais les obstacles qui limitent l'accès à la CPC sont nombreux au niveau de l'information et de la qualité des services dans cette situation d'urgence. Discussion et conclusion: La sensibilisation des adolescents et des jeunes aux conditions d'utilisation de la CPC est nécessaire, et doit être associée à un effort de formation des professionnels et de qualité des services pour faciliter l'accès à la CPC. Mots-clefs: contraception d’urgence, contraception post-coïtale, pilule du lendemain, adolescents.
description: Purpose: To describe and analyze emergency contraception (EC) awareness and use among sexually active Swiss teenagers. Methods: Anonymous computerized questionnaires were distributed to a national representative sample of 4283 in-school adolescents (aged 16 to 20 years) in high schools and professional centers. Young people who were sexually active (51.5% of the sample: 1058 girls and 1073 boys) responded to questions on EC awareness and use and on sexual perception, attitude and behaviors. Univariate analyses and multiple regression analyses were used to describe EC awareness and use and their correlates. Results: Most of the sexually active girls (89.3%) and boys (75.2%) knew of the existence of EC. Of girls, 20% reported having used EC, and the majority of them used it only once (64.1%) or twice (18.5%). EC awareness was positively associated with the father's level of education (girls: odds ratio:5.18), and the scholastic curriculum of the respondent. Gender differences in the correlates of EC awareness demonstrate that girls who had a confidant, or a group of friends or boys of Swiss nationality and those who have had the opportunity to discuss the issue of contraception declare greater awareness of EC. EC use was higher among girls who lived in urban areas (odds ratio: 1.91) and occasionally had unprotected intercourse. We did not find any significant difference in the profile of multiple vs. one-time users. Conclusion: EC awareness and use should be improved through better information and accessibility, especially among teenagers who place themselves in at-risk situations. Keywords: Adolescents, Emergency contraception, Gender differences, Teenage pregnancy prevention, Switzerland.

description: In this article, we show how asteroseismology and spectropolarimetry allow to probe dynamical processes in massive star interiors. First, we give a summary of the state-of-the-art. Second, we recall the MHD mechanisms that take place in massive stars. Next, we show how asteroseimology gives strong constraints on the internal mixing and transport of angular momentum while spectropolarimetry allows to unravel the role played by magnetic fields.

description: Presentation slides 'PIDs for research (data) repositories'; presentation held Thursday January 28, 2021, 11:00 - 11:30 UTC at PIDapalooza 2021. Abstract “Every day, once a day, give yourself a present. Don't plan it. Don't wait for it. Just let it happen. It could be [...] a catnap in your office chair, [...] two cups of good, hot black coffee… or PIDs for research repositories.” (an almost original quotation from Twin Peaks) The re3data COREF project invites all participants to join us with a delicious piece of cake and a nice cup of coffee or tea to discuss the topic of PIDs for research (data) repositories. There will be pie charts and people are allowed to take notes on their table cloths. Of course we are interested in everyone’s opinion and will collect them via polling throughout the session. We are excited to discuss with the community how y’all would use a PID to refer to a repository and how references to repositories can be improved.

description: In this study, nanocrystalline ZnO (NC ZnO) films are considered as interface layers for polymer/metal bonds consisting of hot-dip galvanised steel (HDG) and epoxy resin. NC ZnO films with a thickness of less than one micrometre were deposited on HDG through hydrothermal deposition from aqueous Zn nitrate/hexamethylenetetramine electrolytes. Furthermore, 3-aminopropylphosphonic acid (APPA) and 3-aminopropyltriethoxysilane (γ-APS) were considered for molecular adhesion-promoting layers. 90°-peel tests of water-saturated epoxy films confirm the improvement of bond strength under humid environments. Electrochemical properties of the thin film coatings analysed by current density potential curves indicate effective inhibition of oxygen reduction and metal alloy dissolution. Scanning Kelvin probe (SKP) measurements confirm that the corrosive delamination of the polymer from the metal substrate is significantly slowed down by the considered surface modifications. The combination of NC ZnO films with APPA as an adhesion promoting molecule showed the best performances.

description: The evolution of millimetric-range electrostatic force between a silicon cantilever and a negatively charged dielectric sample was studied by recording “suspended” force curves at a fixed distance on an atomic force microscope (AFM). Results show that the long-range force increases sharply at first with time, then increases moderately until reaching a global maximum, and at last decreases slightly and exponentially. The sharp increase was attributed to carrier drift at a high velocity. Moreover, a repelling electric field due to accumulated charges leads to the moderate increasing trend. In addition, the exponential decrease was attributed to charge decay on the sample surface. With the absence of the sample for a while (absent time) and presence again, the force increases sharply again with a lower value. The longer the absent time, the larger the decreasing rate. This was attributed to carrier diffusion due to the concentration difference. The proposed method can be used to measure millimetric-range electrostatic forces at a fixed distance, and investigate its evolution with time, and study the effect of some factors on the charge dissipation. Furthermore, the outcomes may suggest that charge carriers inside an AFM silicon cantilever play a part in the electrostatic force contribution.
Bottomonium spectroscopy and radiative transitions involving the chi_bJ(1P,2P) states at BABAR

description: We use $(121\pm1)$ million $Υ(3S)$ and $(98\pm1)$ million $Υ(2S)$ mesons recorded by the BABAR detector at the PEP-II $e^+e^-$ collider at SLAC to perform a study of radiative transitions involving the $χ_{b\mathrm{J}}(1P,2P)$ states in exclusive decays with $μ^+μ^-γγ$ final states. We reconstruct twelve channels in four cascades using two complementary methods. In the first we identify both signal photon candidates in the Electromagnetic Calorimeter (EMC), employ a calorimeter timing-based technique to reduce backgrounds, and determine branching-ratio products and fine mass splittings. These results include the best observational significance yet for the $χ_{b0}(2P)\rightarrowγΥ(2S)$ and $χ_{b0}(1P)\rightarrowγΥ(1S)$ transitions. In the second method, we identify one photon candidate in the EMC and one which has converted into an $e^+e^-$ pair due to interaction with detector material, and we measure absolute product branching fractions. This method is particularly useful for measuring $Υ(3S)\rightarrowγχ_{b1,2}(1P)$ decays. Additionally, we provide the most up-to-date derived branching fractions, matrix elements and mass splittings for $χ_b$ transitions in the bottomonium system. Using a new technique, we also measure the two lowest-order spin-dependent coefficients in the nonrelativistic QCD Hamiltonian.

This data correspond to pre-processed raw data generated within the EU-funded FP7-NANOSOLUTIONS project (http://nanosolutionsfp7.com) which aimed at implementing a multi-layered, omics-driven systems toxicology approach for ENM grouping and prioritization. The data were pre-processed by Greco's lab (https://github.com/Greco-Lab). This repository also includes Pre-processed omics datasets (ready for the supervised modelling) -- in NANODAT.zip Pre-processed toxicity data, which are used for the definition of the classification and regression tasks -- in NANODAT.zip R/Python scripts needed to reproduce the results that are shown in an upcoming paper.

description: https://nanosolutionsfp7.com/ The overarching aim of the NANOSOLUTIONS consortium is to provide a means to develop a safety classification for engineered nanomaterials (ENM) based on an understanding of their interactions with living organisms at molecular, cellular and organism levels. The objective is to determine the "biological identity" of ENM, and subsequently develop a computer program that can predict from the properties of ENM their ability to cause health or environmental hazards. New innovative methods are needed for the ENM risk assessment of ENM safety, i.e. ENM SAFETY CLASSIFIER. This will allow for the crucial transition from descriptive toxicology to predictive toxicology.

ffect of Integrated Nutrient Management on performance of Rice-Wheat cropping system and Soil Health
Creators: name: Dushyant Sirohi1, P.K. Singh1 and Pradeep Kumar2
Publisher: name: The Science world a Monthly e magazine
Year: 2023

description: Soil fertility and nutrient management is one of the key factors of crop production, which directly affects the crop yield and quality. The rice-wheat cropping system (RW) is the predominant cropping system of Indo-Gangatic plains of India. After the introduction of green revolution, the yield and productivity of rice and wheat increased tremendously with the introduction of high yielding varieties and the adoption of improved management practices but higher application rates of inputs to meet the food demands of increasing population led to the serious problem of depletion of soil health which is further causing a threat to the sustainability of RW cropping system. The major causes of the decline in productivity of continuous RW cropping system are inherently low fertility status, appearance of multiple nutrient deficiencies, and imbalanced use of synthetic fertilizers, groundwater depletion, soil salinisation and inadequate system diversity. So, improvement in soil health and quality for sustained agricultural production is very vital for food and nutritional security of India and it can be possible through integrated nutrient management i.e., integrated use of synthetic and organic manures which not only sustains the crop yield and increases the soil fertility in long term, but also enhances the nutrient use efficiency. Therefore, to maintain the soil sustainability and increase RW productivity in long term, a balanced and integrated use of organic and inorganic fertilizer is the best option.

A variety of funders, publishers, and scientific organizations around the world refer to re3data within their guidelines and policies, recommending the service to researchers looking for appropriate repositories for storage and discovery of research data. The presentation focuses on the development of the Conceptual Model for User Stories for the re3data service. Since its launch in 2012, re3data has been designed to support open science activities. The registry serves the needs of heterogeneous user groups, first of all aimed at researchers searching for suitable repositories to find and deposit research data. In addition, re3data contributes to other open science infrastructures as a valuable source of metadata about research data repositories. To better understand the needs of its users the re3data COREF project conducted a stakeholder survey. Participants were also invited to join an associated online workshop to further discuss their requirements and recommendations (see Report ). The presentation introduces on the most important findings from these activities and introduce common use cases of re3data. It addresses how re3data currently interlinks with several other services and how the integration of third-party information can be realized.

description: The optimization of real scalar functions of quaternion variables, such as the mean square error or array output power, underpins many practical applications. Solutions often require the calculation of the gradient and Hessian, however, real functions of quaternion variables are essentially non-analytic. To address this issue, we propose new definitions of quaternion gradient and Hessian, based on the novel generalized HR (GHR) calculus, thus making possible efficient derivation of optimization algorithms directly in the quaternion field, rather than transforming the problem to the real domain, as is current practice. In addition, unlike the existing quaternion gradients, the GHR calculus allows for the product and chain rule, and for a one-to-one correspondence of the proposed quaternion gradient and Hessian with their real counterparts. Properties of the quaternion gradient and Hessian relevant to numerical applications are elaborated, and the results illuminate the usefulness of the GHR calculus in greatly simplifying the derivation of the quaternion least mean squares, and in quaternion least square and Newton algorithm. The proposed gradient and Hessian are also shown to enable the same generic forms as the corresponding real- and complex-valued algorithms, further illustrating the advantages in algorithm design and evaluation.

Nickel and cobalt transfigured natural clay: a green catalyst for low-temperature catalytic soot oxidation
Creators: Laishram, Devika
Publisher: name: University of Alberta Library
Year: 2022

Soot particulates in engine exhausts pose a severe threat to the environment and human health – causing cancer, affecting the heart and lungs and drives metal processes. This study proposes a practical, real-world application of transition metal modified natural clay as an environmentally benign, low-cost, green catalyst for soot oxidation. Ni and Co (NC-Clay) incorporated natural clay catalysts were prepared by a simple wet impregnation method and meticulously characterized by different characterization techniques. The catalyst exhibited higher H2 absorption at a lower temperature with similar trends as observed in O2 TPD that indicated a remarkable redox property, which is useful for applications as a catalyst in soot oxidation. Excellent catalytic activity with a very low T50 of 358 °C was observed and can be accredited to the improved surface oxygen vacancies and thermal stability by the metal modification of clay.

description: We review recently introduced numerical methods for the unbiased detection of the order parameter and/or dominant correlations, in many-body interacting systems, by using reduced density matrices. Most of the paper is devoted to the "quasi-degenerate density matrix" (QDDM) which is rooted in Anderson's observation that the degenerate symmetry-broken states valid in the thermodynamic limit, are manifested in finite systems as a set of low-energy "quasi-degenerate" states (in addition to the ground state). This method, its original form due to Furukawa et al.[Phys. Rev. Lett. 96, 047211 (2006)], is given a number of improvements here, above all the extension from two-fold symmetry breaking to arbitrary cases. This is applied to two test cases (1) interacting spinless hardcore bosons on the triangular lattice and (2) a spin-1/2 antiferromagnetic system at the percolation threshold. In addition, we survey a different method called the "correlation density matrix", which detects (possibly long-range) correlations only from the ground state, but using the reduced density matrix from a cluster consisting of two spatially separated regions.

description: Asteroid spectroscopy reflects surface mineralogy. There are few thousand asteroids whose surfaces have been observed spectrally. Determining the surface properties of those objects is important for many practical and scientific applications, such as for example developing impact deflection strategies or studying history and evolution of the Solar System and planet formation. The aim of this study is to develop a pre-selection method that can be utilized in searching for asteroids of any taxonomic complex. The method could then be utilized im multiple applications such as searching for the missing V-types or looking for primitive asteroids. We used the Bayes Naive Classifier combined with observations obtained in the course of the Sloan Digital Sky Survey and the Wide-field Infrared Survey Explorer surveys as well as a database of asteroid phase curves for asteroids with known taxonomic type. Using the new classification method we have selected a number of possible V-type candidates. Some of the candidates were than spectrally observed at the Nordic Optical Telescope and South African Large Telescope. We have developed and tested the new pre-selection method. We found three asteroids in the mid/outer Main Belt that are likely of differentiated type. Near-Infrared are still required to confirm this discovery. Similarly to other studies we found that V-type candidates cluster around the Vesta family and are rare in the mid/oter Main Belt. The new method shows that even largely explored large databases combined together could still be further exploited in for example solving the missing dunite problem.

description: We present a homological characterisation of those chain complexes of modules over a Laurent polynomial ring in several indeterminates which are finitely dominated over the ground ring (that is, are a retract up to homotopy of a bounded complex of finitely generated free modules). The main tools, which we develop in the paper, are a non-standard totalisation construction for multi-complexes based on truncated products, and a high-dimensional mapping torus construction employing a theory of cubical diagrams that commute up to specified coherent homotopies.

Conflict and co-operation in ant societies
Creators: name: Reuter, Max
Publisher: name: Unknown
Year: 0

description: Cette thèse se propose d’étudier les forces évolutives qui influencent la bal- ance entre coopération et conflit. Deux exemples sont analysés en détail, les sociétés d’insectes et l’association entre la fourmi Formica exsecta et son sym- bionte intracellulaire Wolbachia. Chacune de ces deux associations animales est caractérisée par la coexistence de coopération et de conflit. Les colonies d’insectes sociaux sont un exemple typique de coopération. Néanmoins, la détermination haplodiploïde du sexe crée des apparentements asymétriques entre les membres de la colonie qui se traduisent par des con- flits entre reines et ouvrières. Un des conflits les plus importants porte sur le sexe-ratio, l’investissement optimal en sexués males et femelles étant équilibré pour la reine, mais biaisé en faveur des femelles pour les ouvrières. Jusqu’ici, les modèles étudiant ce conflit se basaient uniquement sur les asymétries d’ap- parentement. La première partie de cette thèse (Chapitres 1 et 2) propose d’introduire dans des modèles de sexe-ratio les mécanismes proximaux utilisés par les deux parties pour influencer le sexe-ratio. Ces mécanismes, par leurs ef- fets négatifs sur la productivité de la colonie, peuvent entraîner des déviations importantes du sexe-ratio par rapport à la valeur prédite par des modèles clas- siques. De plus, la prise en compte de ces mécanismes nous permet d’étudier dans quelle mesure les parties opposées sont sélectionnées pour influencer le sexe-ratio. Enfin, les modèles génèrent des prédictions quant à l’issue du con- flit, c’est-à-dire un compromis où reines et ouvrières partagent le contrôle de l’investissement. La seconde partie du travail porte sur l’infection de la fourmi Formica ex- secta par le symbionte cytoplasmique Wolbachia. Ce symbionte, présent chez un grand nombre d’espèces d’Arthropodes, est transmis maternellement. Afin de se répandre dans la population d’hôtes, Wolbachia manipule la physiolo- gie reproductive de l’organisme qui l’abrite. Le Chapitre 3 décrit une étude consacrée aux variations du sexe-ratio produit dans des colonies de fourmis’ en fonction de la présence ou de l’absence de Wolbachia. Le Chapitre 4 étudie l’association entre les lignées du symbionte et les haplotypes mitochondriaux des hôtes. L’étude de l’association entre les deux éléments maternellement transmis est d’un intérêt particulier chez Formica exsecta car le taux de migra- tion femelle très faible engendre une forte strucure génétique mitochondriale.

Development of a hepatocyte hollow fiber bioreactor for the study of contrast agents by magnetic resonance imaging
Creators: name: Planchamp Messeiller, Corinne
Publisher: name: Unknown
Year: 0

description: Thanks to the continuous progress made in recent years, medical imaging has become an important tool in the diagnosis of various pathologies. In particular, magnetic resonance imaging (MRI) permits to obtain images with a remarkably high resolution without the use of ionizing radiation and is consequently widely applied for a broad range of conditions in all parts of the body. Contrast agents are used in MRI to improve tissue discrimination. Different categories of contrast agents are clinically available, the most widely used being gadolinium chelates. One can distinguish between extracellular gadolinium chelates such as Gd-DTPA, and hepatobiliary gadolinium chelates such as Gd-BOPTA. The latter are able to enter hepatocytes from where they are partially excreted into the bile to an extent dependent on the contrast agent and animal species. Due to this property, hepatobiliary contrast agents are particularly interesting for the MRI of the liver. Actually, a change in signal intensity can result from a change in transport functions signaling the presence of impaired hepatocytes, e.g. in the case of focal (like cancer) or diffuse (like cirrhosis) liver diseases. Although the excretion mechanism into the bile is well known, the uptake mechanisms of hepatobiliary contrast agents into hepatocytes are still not completely understood and several hypotheses have been proposed. As a good knowledge of these transport mechanisms is required to allow an efficient diagnosis by MRI of the functional state of the liver, more fundamental research is needed and an efficient MRI compatible in vitro model would be an asset. So far, most data concerning these transport mechanisms have been obtained by MRI with in vivo models or by a method of detection other than MRI with cellular or sub-cellular models. Actually, no in vitro model is currently available for the study and quantification of contrast agents by MRI notably because high cellular densities are needed to allow detection, and no metallic devices can be used inside the magnet room, which is incompatible with most tissue or cell cultures that require controlled temperature and oxygenation. The aim of this thesis is thus to develop an MRI compatible in vitro cellular model to study the transport of hepatobiliary contrast agents, in particular Gd-BOPTA, into hepatocytes directly by MRI. A better understanding of this transport and especially of its modification in case of hepatic disorder could permit in a second step to extrapolate this knowledge to humans and to use the kinetics of hepatobiliary contrast agents as a tool for the diagnosis of hepatic diseases.

description: Abstrak
Madrasah Ibtidaiyah as a formal educational institution in Indonesia requires an educational planning design model so that it can suit local needs but is also synergistic with national programs and global developments. This research seeks to obtain a design model for madrasa education planning by conducting qualitative research using a case study method at one of the Madrasah Ibtidaiyah (MI) in the city of Bandung. The research was conducted at MI Permata Bangsa Bandung by focusing on the management stages of planning, organizing, implementing and evaluating. The research results show that MI Permata Bangsa has an educational planning design model using the SWOT approach. This model has been implemented and is in accordance with the needs of the madrasah so that it can meet local needs and can synergize with national education developments and global paradigm changes.
Universal Order Parameters and Quantum Phase Transitions: A Finite-Size Approach

description: We propose a method to construct universal order parameters for quantum phase transitions in many-body lattice systems. The method exploits the $H$-orthogonality of a few near-degenerate lowest states of the Hamiltonian describing a given finite-size system, which makes it possible to perform finite-size scaling and take full advantage of currently available numerical algorithms. An explicit connection is established between the fidelity per site between two $H$-orthogonal states and the energy gap between the ground state and low-lying excited states in the finite-size system. The physical information encoded in this gap arising from finite-size fluctuations clarifies the origin of the universal order parameter.We demonstrate the procedure for the one-dimensional quantum formulation of the $q$-state Potts model, for $q=2,3,4$ and 5, as prototypical examples, using finite-size data obtained from the density matrix renormalization group (DMRG) algorithm.

Model comparison with composite likelihood information criteria
Creators: name: Ng, Chi Tim

Publisher: name: arXiv
Year: 2014
Subjects: subject: Statistics Theory (math.ST)
subject: FOS: Mathematics

description: Comparisons are made for the amount of agreement of the composite likelihood information criteria and their full likelihood counterparts when making decisions among the fits of different models, and some properties of penalty term for composite likelihood information criteria are obtained. Asymptotic theory is given for the case when a simpler model is nested within a bigger model, and the bigger model approaches the simpler model under a sequence of local alternatives. Composite likelihood can more or less frequently choose the bigger model, depending on the direction of local alternatives; in the former case, composite likelihood has more "power" to choose the bigger model. The behaviors of the information criteria are illustrated via theory and simulation examples of the Gaussian linear mixed-effects model.
