description: Objectif : cette recherche a été réalisée dans le cadre d’un Travail de Bachelor. Nous nous sommes intéressées aux différents vécus des patientes atteintes d’un cancer du sein gauche, traitées par radiothérapie avec synchronisation respiratoire. L’enjeu est d’identifier quels sont les différents ressentis des patientes en fonction de la technique utilisée : la méthode ABC™ ou la technique RPM™. Méthode : il s’agit d’une recherche de type exploratoire descriptif. Quatre patientes ont été interviewées : deux traitées avec la méthode ABC™ et deux avec la technique RPM™. Résultats et discussion : Toutes les patientes ont invoqué l’importance d’une relation chaleureuse et de confiance avec l’équipe soignante dans leur parcours thérapeutique. Nous avons noté une grande différence de compréhension des enjeux liés au traitement entre les deux groupes de patientes. Les patientes traitées avec la méthode ABC™ présentaient une compréhension claire des enjeux. Cela s’est présenté comme un élément pesant pour elles : celles-ci avaient craintes de mal faire les exercices d’apnée, engendrant ainsi des répercussions sur leur santé. Les patientes traitées avec la méthode RPM™ présentent une compréhension superficielle des enjeux et mettent en avant la relation harmonieuse avec l’équipe soignante comme plus-value dans le vécu de leur traitement. Au vu du faible nombre de patientes interrogées, il est important de prendre du recul vis-à-vis des résultats. Conclusion : L’appréhension du traitement de la part des patientes est influencée par un grand nombre d’éléments gravitant autour d’elles. Il est donc important d’apporter une attention soutenue aux patientes durant leurs traitements.

description: The twenty years since the announcement of the proton spin crisis by the European Muon Collaboration has seen tremendous progress in our knowledge of the distribution of spin within the proton. The problem is reviewed, beginning with the original data and the suggestion that polarized gluons may play a crucial role in resolving the problem through the U(1) axial anomaly. The discussion continues to the present day where not only have strong limits have been placed on the amount of polarized glue in the proton but the experimental determination of the spin content has become much more precise. It is now clear that the origin of the discrepancy between experiment and the naive expectation of the fraction of spin carried by the quarks and anti-quarks in the proton lies in the non-perturabtive structure of the proton. We explain how the features expected in a modern, relativistic and chirally symmetric description of nucleon structure naturally explain the current data.

description: Text detection/localization, as an important task in computer vision, has witnessed substantialadvancements in methodology and performance with convolutional neural networks. However, the vastmajority of popular methods use rectangles or quadrangles to describe text regions. These representationshave inherent drawbacks, especially relating to dense adjacent text and loose regional text boundaries,which usually cause difficulty detecting arbitrarily shaped text. In this paper, we propose a novel text regionrepresentation method, with a robust pipeline, which can precisely detect dense adjacent text instances witharbitrary shapes. We consider a text instance to be composed of an adaptive central text region mask anda corresponding expanding ratio between the central text region and the full text region. More specifically,our pipeline generates adaptive central text regions and corresponding expanding ratios with a proposedtraining strategy, followed by a new proposed post-processing algorithm which expands central text regionsto the complete text instance with the corresponding expanding ratios. We demonstrated that our new textregion representation is effective, and that the pipeline can precisely detect closely adjacent text instances ofarbitrary shapes. Experimental results on common datasets demonstrate superior performance o

description: Notre travail a pour but la quantification de pneumothorax en CT post-mortem et l’importance de ce dernier dans la cause du décès grâce à des outils informatiques permettant cette quantification. Pour se faire, nous avons utilisé trois méthodes de quantification. : - La méthode Contourage ; - La méthode Segmentation par coupe, qui sont des méthodes que nous avons tirées de nos cours d’imagerie et adaptées à notre étude. - La méthode Mialite, qui, elle, a été reprise d’une recherche à but de comparaison. Pour cette étude, nous avons quantifié 40 cas provenant de la base de données du Centre Universitaire Romand de Médecine Légale. Le critère d’inclusion était la présence d’un pneumothorax simple ou bilatéral. Les critères d’exclusion sont un état de putréfaction avancée déterminé par un RAI au-dessus de 60 et une clinique du décès ayant un impact physique important sur le corps entrainant de ce fait un pneumothorax faussé. Les cas ont été choisis sur la période de 2014 à 2016. Nous avons démontré avec cette étude la faible variabilité entre les trois méthodes sur des cas de pneumothorax bien définis. Cette dernière augmente en présence de poumons emphysémateux et de zones poussant le logiciel dans ses limites en termes de résolution. Nous avons établi les avantages et les inconvénients de chaque méthode. Finalement, nous avons démontré que le volume du pneumothorax n’était pas un aspect qui était investigué dans le cadre de la recherche de la cause du décès, mais cela peut être mis en lien avec le fait qu’il n’y avait pas d’outils de ce genre à disposition. En conclusion, nous avons constaté que nos méthodes nécessitent une optimisation informatique importante pour être utilisées couramment en pratique, par conséquent nous recommandons Mialite pour sa rapidité et son efficacité.

description: This paper presents a methodology to efficiently explore the design space of communication adapters. In most digital signal processing (DSP) applications, the overall performance of the system is significantly affected by communication architectures, as a consequence the designers need specifically optimized adapters. By explicitly modeling these communications within an effective graph-theoretic model and analysis framework, we automatically generate an optimized architecture, named Space-Time AdapteR (STAR). Our design flow inputs a C description of Input/Output data scheduling, and user requirements (throughput, latency, parallelism...), and formalizes communication constraints through a Resource Constraints Graph (RCG). Design space exploration is then performed through associated tools, to synthesize a STAR component under time-to-market constraints. The proposed approach has been tested to design an industrial data mixing block example: an Ultra-Wideband interleaver.

description: Abstract: This thesis is a comparative analysis of the reasons for the differences in success of the drug prohibition policies of Japan, and England and Wales. These countries are both large, highly developed island nations with histories of overseas colonial expansion, parliamentary liberal-democracies, constitutional monarchies and ministerial civil services. Their drug policies, while using very similar laws, are vastly different in outcome. I will attempt to explain the differences in the extent of drug use in terms of Situational Action Theory (temptation, deterrence, and law-relevant morality), adapted to a national scale. This is achieved through a historical institutionalist analysis, supported by a comprehensive survey of the available nationwide statistical indicators, creating a thick description of the policy environment affecting each variable.

description: Introduction : Certaines croyances sont un facteur de risque de passage à la chronicité de la lombalgie. Elles peuvent conduire à des comportements délétères susceptibles de favoriser un mauvais pronostic. Objectif : Identifier les croyances sur le mal de dos d’une partie de la population en Suisse romande. Méthodologie : Diffusion du questionnaire Back-PAQ via les réseaux sociaux auprès de la population cible, selon des critères d’inclusion et d’exclusion. Résultats : 1129 données exploitables : 71% de femmes, âge moyen : 36,07 (±13,27) ; 62% de formation tertiaire ; 96% ayant déjà eu des douleurs de dos. Le score total moyen est de 113,24 (±10,61). Des croyances délétères ont été identifiées, telles que le besoin de protéger son dos, la spécificité des douleurs, l’importance d’en identifier les causes et la nécessité de consulter. Néanmoins, des bonnes croyances ont également été constatées, comme l’importance de rester actif et la dimension psychosociale de la lombalgie. Discussion : Le dos est perçu comme fort et bien conçu, mais parallèlement, les participants pensent qu’il est facile de le blesser et que des muscles forts sont nécessaires. L’activité physique est considérée comme bénéfique, mais seulement à une certaine intensité. Ces contradictions laissent supposer que les croyances ne concordent que partiellement avec les recommandations actuelles. Conclusion : Certaines croyances délétères sont présentes dans notre échantillon, sans toucher de catégorie particulière, soulignant l’importance d’aborder les patients lombalgiques dans leur globalité. Des recherches supplémentaires seraient nécessaires pour explorer les paradoxes mis en évidence dans ce travail.

description: A search for exotic mesons in the $π^{+}π^{+}π^{-}$ system photoproduced by the charge exchange reaction $γp\to π^{+}π^{+}π^{-}(n)$ was carried out by the CLAS collaboration at Jefferson Lab. A tagged-photon beam with energies in the 4.8 to 5.4 GeV range, produced through bremsstrahlung from a 5.744 GeV electron beam, was incident on a liquid-hydrogen target. A Partial Wave Analysis (PWA) was performed on a sample of 83,000 events, the highest such statistics to date in this reaction at these energies. The main objective of this study was to look for the photoproduction of an exotic $J^{PC} = 1^{-+}$ resonant state in the 1 to 2 GeV mass range. Our PWA analysis, based on the isobar model, shows production of the $a_{2}(1320)$ and the $π_{2}(1670)$ mesons, but no evidence for the $a_{1}(1260)$, nor the $π_{1}(1600)$ exotic state at the expected levels. An upper limit of 13.5 nb is determined for the exotic $π_1(1600)$ cross section, less than 2% of the $a_2(1320)$ production.

An approach to developing comprehensive musicianship in the intermediate grades using the voice and the ukulele
Creators: name: Madhosingh, Donna-Faye
Publisher: name: University of British Columbia
Year: 2010

description: As the majority of experimentation in comprehensive musicianship has been done at the university and high school levels, there is a need for similar research at the elementary level. This study is designed to produce a specific programme aimed at developing comprehensive musicianship and predicting its success in music education. The work is unique in that it incorporates a vocal method devised in Hungary and adapts it not only to another country but also applies it to and combines it with an instrumental programme from Canada. This thesis is based on research by the author in comprehensive musicianship, and the Kodaly principles and concepts of music education, which are used to construct a strategy for an effective music teaching programme in the intermediate grades, utilizing the dual media of voice and ukulele. The strategy, which can be used appropriately by the music specialist, is devised from the author's research, classroom music teaching experience and studies in music' education in Hungary, Finland, the United States and Canada. The Kodaly concepts have been adapted to meet the needs and interests of intermediate pupils, their voices and ranges, and the technical requirements necessary for the ukulele. The programme seeks in-depth development of concepts through preparation, presentation and reinforcement. Conceptual understanding and intrinsic involvement leading towards aesthetic appreciation are encouraged. The concepts are presented under the headings of linear pitch, vertical pitch, form, timbre, dynamics, tempo and style. The basic aural, translatable and dextral skills are incorporated in the performing, analyzing and organizing activities. The cyclical, sequential and concept based process presented is to be continually analyzed and evaluated by the teacher in a task-oriented manner in order to assess the competencies gained by the students. A comprehensive pitch recognition programme, developed and implemented by the author, was carried out with grade six and seven students. Pre- and post-pitch recognition tests were administered to two different treatment groups, one on a traditional music programme and the other on a comprehensive musicianship programme. The results of the study showed a statistically significant difference of the comprehensive musicianship programme group over the traditional music programme group (p<.05). The instructional procedure presented begins with a vocal readiness programme in Phase I. Following is the dual approach of voice and ukulele in Phase II and III. This sequential, experiential approach is designed to promote and enhance the development of comprehensive musicianship in the intermediate grades.

description: Stellar feedback in dwarf galaxies plays a critical role in regulating star formation via galaxy-scale winds. Recent hydrodynamical zoom simulations of dwarf galaxies predict that the periodic outward flow of gas can change the gravitational potential sufficiently to cause radial migration of stars. To test the effect of bursty star formation on stellar migration, we examine star formation observables and sizes of 86 local dwarf galaxies. We find a correlation between the R-band half-light radius (R$_e$) and far-UV luminosity (L$_{FUV}$) for stellar masses below 10$^8 $ M$_{\odot}$ and a weak correlation between the R$_e$ and H$α$ luminosity (L$_{Hα}$). We produce mock observations of eight low-mass galaxies from the FIRE-2 cosmological simulations and measure the similarity of the time sequences of R$_e$ and a number of star formation indicators with different timescales. Major episodes of R$_e$ time sequence align very well with the major episodes of star formation, with a delay of $\sim$ 50 Myrs. This correlation decreases towards SFR indicators of shorter timescales such that $R_e$ is weakly correlated with L$_{FUV}$ (10-100 Myr timescale) and is completely uncorrelated with L$_{Hα}$ (a few Myr timescale), in agreement with the observations. Our findings based on FIRE-2 suggest that the R-band size of a galaxy reacts to star formation variations on a $\sim50$ Myr timescale. With the advent of a new generation of large space telescopes (e.g., JWST), this effect can be examined explicitly in galaxies at higher redshifts where bursty star formation is more prominent.

description: We explore whether the axion which solves the strong CP problem can naturally be much lighter than the canonical QCD axion. The $Z_\mathcal{N}$ symmetry proposed by Hook, with $\mathcal{N}$ mirror and degenerate worlds coexisting in Nature and linked by the axion field, is considered in terms of generic effective axion couplings. We show that the total potential is safely approximated by a single cosine in the large $\mathcal{N}$ limit, and we determine the analytical formula for the exponentially suppressed axion mass. The resulting universal enhancement of all axion interactions relative to those of the canonical QCD axion has a strong impact on the prospects of axion-like particle experiments such as ALPS II, IAXO and many others. The finite density axion potential is also analyzed and we show that the $Z_\mathcal{N}$ asymmetric background of high-density stellar environments sets already significant model-independent constraints: $3\le\mathcal{N}\lesssim47$ for an axion scale $f_a\lesssim 2.4\times10^{15}$ GeV, with tantalizing discovery prospects for any value of $f_a$ and down to $\mathcal{N}\sim9$ with future neutron star and gravitational wave data, down to the ultra-light mass region. In addition, two specific ultraviolet $Z_\mathcal{N}$ completions are developed: a composite axion one and a KSVZ-like model with improved Peccei-Quinn quality.

description: The advent of ferromagnetism in two-dimensional (2D) van der Waals (vdW) magnets has stimulated high interest in exploring topological magnetic textures, such as skyrmions for use in future skyrmion-based spintronic devices. To engineer skyrmions in vdW magnets by transforming Bloch-type magnetic bubbles into Néel-type skyrmions, the heterostructure of heavy metal/vdW magnetic thin film has been made to induce interfacial Dzyaloshinskii-Moriya interaction (DMI). However, the unambiguous identification of the magnetic textures inherent to vdW magnets, e.g., whether the magnetic twists (skyrmions/domain walls) are Néel- or Bloch-type, is unclear. Here we demonstrate that the Néel- or Bloch-type magnetic twists can be tuned in the vdW magnet Fe3GeTe2 (FGT) with/without interfacial DMI. We use an in-plane magnetic field to align the modulation wavevector q of the magnetizations in order to distinguish the Néel- or Bloch-type magnetic twists. We observe that q is perpendicular to the in-plane field in the heterostructure (Pt/oxidized-FGT/FGT/oxidized-FGT), while q aligns at a rotated angle with respect to the field direction in the thin plate by thinning bulk FGT. We find that the aligned domain wall twists hold fan-like modulations, coinciding qualitatively with our computational results.

description: This paper suggests a full protocol of Computer Aided Surgery as previously recommended in literature addressing the challenging task of primary or secondary reconstruction of orbito-zygomatic dislocation. First, on a specifically developed planning software, the best zygoma reduction and orbital boundaries reconstruction to achieve skeletal symmetry are determined. This treatment plan is then transferred to the 3D Navigation Systems within the operating room. After patient's anatomy registration to his preoperative CT scan data, the navigation system allows zygomatic guiding to its planned reduced location and bone orbital volume restoration control. The feasibility of this technique was checked in 3 patients with major orbito-zygomatic deformities. Preliminary clinical results are presented.

Trois tensions différentes ont été utilisées, 60, 75 et 120 kV. Les mesures ont été réalisées sur un fantôme anthropomorphique au travers de diverses incidences. Deux grilles de ratio 10, l’une avec une focalisation à 115 cm et l’autre à une focalisation de 150 cm ont été évaluées. Les résultats montrent que l’emploi d’une grille devient utile dès 10 cm d’épaisseur de tissus mous et derrière le tissu osseux. Nous préconisons un changement de pratique pour les incidences des jambes de face et les genoux de face. La grille augmente fortement le SNR derrière le tissu osseux, et donc est utile dans l’exploration ostéoarticulaire. Nous recommandons aussi pour les incidences nécessitant l’utilisation d’une grille, de toujours en employer une, même si elle n’est pas à la bonne focalisation.

The results showed that effective information along with other factors such as membership in a farmer organisation, availability of labourers, irrigation facility and so forth were important in determining the SRI adoption. The results also revealed that the Government of India’s National Food Security Mission programme did not have significant impact in promoting greater dissemination and adoption of SRI.

description: This annotation focuses on the phenomenon of word formation through compounding, a productive process that involves combining two or more existing words to create a new word with a distinct meaning. The author investigates the role of compounding in expanding the lexical inventory of a language and analyzes its compositional nature. The annotation explores different types of compounds, such as noun-noun compounds, verb-noun compounds, and adjective-noun compounds, highlighting the structural and semantic relationships between the constituent words. Drawing on linguistic theories and empirical research, the article discusses the cognitive processes involved in compounding and examines the factors that influence the productivity and creativity of compound formation. Furthermore, the annotation addresses the challenges posed by compounding in terms of lexical retrieval and semantic compositionality. Overall, this comprehensive analysis contributes to a deeper understanding of the principles and mechanisms underlying word formation through compounding, shedding light on its significance in lexical expansion and linguistic diversity

description: Impulsive orientation of symmetric-top molecules excited by two-color femtosecond pulses is considered. In addition to the well-known transient orientation appearing immediately after the pulse and then reemerging periodically due to quantum revivals, we report the phenomenon of field-free long-lasting orientation. Long-lasting means that the time averaged orientation remains non-zero until destroyed by other physical effects, e.g. intermolecular collisions. The effect is caused by the combined action of the field-polarizability and field-hyperpolarizability interactions. The dependence of degree of long-lasting orientation on temperature and pulse's parameters is considered. The effect can be measured by means of second (or higher-order) harmonic generation, and may be used to control the deflection of molecules traveling through inhomogeneous electrostatic fields.

description: INTRODUCTION Dans le cadre de leur activité professionnelle en médecine nucléaire (MN), les techniciennes en radiologie médicale (TRM) sont plusieurs à travailler durant la période de la grossesse. À savoir qu’en médecine nucléaire les TRM manipulent des sources non-scellées, et sont plus à même d’être exposés à l’irradiation interne par ingestion ou inhalation. Cette étude nous permettra de répondre aux questions concernant les risques liés à l’exposition aux rayonnements ionisants et de savoir comment ces risques sont perçus par les TRM enceintes. Nous pourrons également identifier les aménagements qui sont mis en place afin de faciliter leur travail durant la grossesse, et de savoir comment les TRM vivent les changements amenés par cette situation de femme enceinte. MÉTHODE Nous avons effectué six entretiens semi-dirigés. Nous avons établi un guide d’entretien traitant chacune des thématiques que nous avons évoquées, et nous avons posé des questions ouvertes afin de laisser la TRM s’exprimer sur son vécu. RÉSULTATS Les TRM participantes ont pour la plupart été satisfaites de la conciliation entre leur activité professionnelle et leur grossesse. Elles ont toutes bénéficié d’un changement de poste qui leur permettait de vivre leur grossesse harmonieusement. La plupart d’entre elles a trouvé du soutien de la part des collègues durant cette période. Certaines TRM pensent tout de même que les lois concernant la radioprotection ne sont pas très précises, par conséquent cela a provoqué quelques situations délicates. CONCLUSION La conciliation de la grossesse avec l’activité professionnelle d’une TRM en médecine nucléaire est concevable. Il est tout de même important pour les TRM enceintes de se renseigner sur les obligations et les droits qui sont les leurs durant cette période, et ne pas hésiter à les faire appliquer.

description: This paper connects two important development policy issues: women’s empowerment and land certification. We use propensity score matching to study the impact of the Ethiopian joint land registration and certification programme on women’s empowerment. Data are collected using surveys and a field experiment, enabling construction of complementary indices for empowerment. Our main result is that joint land certification has significant effects on women’s empowerment, particularly on dimensions that indicate female participation and roles outside the home. This result is robust to various sensitivity checks and alternative model specifications.

description: We evaluate the nucleon axial form factor, $G_A(q^2)$, and induced pseudoscalar form factor, $G_p(q^2)$, as well as the pion-nucleon form factor, $G_{πN N}(q^2)$, in lattice QCD. We also evaluate the corresponding nucleon to $Δ$ transition form factors, $C_5^A(q^2)$ and $C_6^A(q^2)$, and the pion-nucleon-$Δ$ form factor $G_{πNΔ}(q^2)$. The nucleon form factors are evaluated in the quenched theory and with two degenerate flavors of dynamical Wilson fermions. The nucleon to $Δ$ form factors, besides Wilson fermions, are evaluated using domain wall valence fermions with staggered sea quark configurations for pion masses as low as about 350 MeV. Using these form factors, together with an evaluation of the renormalized quark mass, we investigate the validity of the diagonal and non-diagonal Goldberger-Treiman relations. The ratios $G_{πNΔ}(q^2)/G_{πNN}(q^2)$ and $2C_5^A(q^2)/G_A(q^2)$ are constant as a function of the momentum transfer squared and show almost no dependence on the quark mass. We confirm equality of these two ratios consistent with the Goldberger-Treiman relations extracting a mean value of $1.61(2)$.

description: The recent rapid increase in demand for data processing has resulted in the need for novel machine learning concepts and hardware. Physical reservoir computing and an extreme learning machine are novel computing paradigms based on physical systems themselves, where the high dimensionality and nonlinearity play a crucial role in the information processing. Herein, we propose the use of multidimensional speckle dynamics in multimode fibers for information processing, where input information is mapped into the space, frequency, and time domains by an optical phase modulation technique. The speckle-based mapping of the input information is high-dimensional and nonlinear and can be realized at the speed of light; thus, nonlinear time-dependent information processing can successfully be achieved at fast rates when applying a reservoir-computing-like-approach. As a proof-of-concept, we experimentally demonstrate chaotic time-series prediction at input rates of 12.5 Gigasamples per second. Moreover, we show that owing to the passivity of multimode fibers, multiple tasks can be simultaneously processed within a single system, i.e., multitasking. These results offer a novel approach toward realizing parallel, high-speed, and large-scale photonic computing.

description: Introduction : Chaque année, 6200 cas de cancers de la prostate sont diagnostiqués en Suisse. Cette maladie représente la deuxième cause de mortalité après le cancer du poumon. Aussi, le taux d’incidence peut être observé à partir de 45-49 ans ce qui signifie que ce cancer n’intéresse plus uniquement le sujet âgé. Actuellement, ce cancer peut être traité par deux techniques d’irradiation sophistiquées : tomothérapie ou arc thérapie. Elles permettent, toutes deux, un contrôle local tumoral et une épargne des organes à risques alentours. Objectif : Réalisation d’une étude dosimétrique comparative entre deux techniques d’irradiation : tomothérapie et arc thérapie. Le but étant de confronter nos résultats avec la littérature. Méthodologie : Réalisation de deux planifications (tomothérapie et arc thérapie), chez trois patients différents atteints d’un cancer à bas risque. Le schéma thérapeutique recommandé par la Société Française de Radiothérapie Oncologique (SFRO) est de 74 Gy divisé en 37 fractions de 2 Gy. Résultats : Plusieurs résultats intéressants peuvent être relevés dans notre étude. Les contraintes de dose, concernant le volume cible et les organes à risques, ont été respectées dans les deux modalités. Cependant, les analyses qualitatives et quantitatives des résultats montrent une couverture du volume cible plus optimale dans le cas du VMAT. Les organes à risques sont, toutefois, davantage protégés avec la tomothérapie. Conclusion : Les différences observées à l’issue de notre étude ne découlent en aucun cas du choix de la technique d’irradiation utilisée, mais principalement de l’expérience du planificateur.

description: It has been suggested that galactic shock asymmetry induced by our galaxy's infall toward the Virgo Cluster may be a source of periodicity in cosmic ray exposure as the solar system oscillates perpendicular to the galactic plane. Here we investigate a mechanism by which cosmic rays might affect terrestrial biodiversity, ionization and dissociation in the atmosphere, resulting in depletion of ozone and a resulting increase in the dangerous solar UVB flux on the ground, with an improved ionization background computation averaged over a massive ensemble (about 7 x 10^5) shower simulations. We study minimal and full exposure to the postulated extragalactic background. The atmospheric effects are greater than with our earlier, simplified ionization model. At the lower end of the range effects are too small to be of serious consequence. At the upper end of the range, ~6 % global average loss of ozone column density exceeds that currently experienced due to effects such as accumulated chlorofluorocarbons. The intensity is less than a nearby supernova or galactic gamma-ray burst, but the duration would be about 10^6 times longer. Present UVB enhancement from current ozone depletion ~3% is a documented stress on the biosphere, but a depletion of the magnitude found at the upper end of our range would double the global average UVB flux. For estimates at the upper end of the range of the cosmic ray variability over geologic time, the mechanism of atmospheric ozone depletion may provide a major biological stress, which could easily bring about major loss of biodiversity. Future high energy astrophysical observations will resolve the question of whether such depletion is likely.

Armed Conflict and Adolescents’ Early Transition to Childbearing

description: We estimate the effect of armed conflict on adolescents’ childbearing transition. Three types of models are estimated: models in origin, which determine the current effect of violence; context change models, which estimate the effect of decreased violence levels; and violence aftermath models, which indicate the groups that do not completely adapt to a peaceful context. Through multilevel logistic models, we find that the coefficient of violence depends on the municipality in where adolescents reside or resided. We conclude that violence promotes the transition to childbearing particularly among rural females. However, a reduction in violence levels reduces the probabilities of childbearing.
Natural Disasters and Social Preferences: The Effect of Tsunami-Memories on Cheating in Sri Lanka

description: This study analyses how past tsunami-memories affect cheating in Sri Lanka. Subjects are assigned to a treatment (control) group in which they watch a video about the calamity before (after) participating in a trust game. Cheating is elicited by asking trustors how much they need to receive not to feel cheated and trustees how much they need to return not to make the trustor feel cheated. Finally, participants report whether the video mostly reminded them about solidarity, looting or the calamity. Trustors show lower cheating standards and trustees more often satisfy the trustors’ cheating notion if they mostly recall solidarity.

description: High-energy photons propagating in the magnetised medium with large velocity gradients can mediate energy and momentum exchange. Conversion of these photons into electron-positron pairs in the field of soft photons with the consequent isotropization and emission of new high-energy photons by Compton scattering can lead to the runaway cascade of the high-energy photons and electron-positron pairs fed by the bulk energy of the flow. This is the essence of the photon breeding mechanism. We study the problem of high-energy emission of relativistic jets in blazars via photon breeding mechanism using 2D ballistic model for the jet with the detailed treatment of particle propagation and interactions. The gamma-ray background of similar energy density as observed at Earth is sufficient to trigger the photon breeding. As a result, a jet can convert up to 80 per cent of its total power into radiation. Photon breeding produces a population of high-energy pairs and predicts the spectra in agreement with observations of blazars (e.g. the blazar sequence). It also decelerates the jet at subparsec scales and induces the transversal gradient of the Lorentz factor which reconcile the discrepancy between the high Doppler factors determined from the spectra of TeV blazars and the low apparent velocities observed at VLBI scales. The broad angular distribution of radiation predicted by the mechanism reconciles the observed statistics and luminosity ratio of FR I and BL Lac objects with the large Lorentz factors of the jets as well as explains the high level of the TeV emission in the radio galaxy M87.

description: We call "projectile fragmentation" of neutron halo nuclei the elastic breakup (diffraction) reaction, when the observable studied is the neutron-core relative energy spectrum. This observable has been measured in relation to the Coulomb breakup on heavy target and recently also on light targets. Such data enlighten the effect of the neutron final state interaction with the core of origin. Projectile fragmentation is studied here by a time dependent model for the excitation of a nucleon from a bound state to a continuum resonant state in a neutron-core complex potential which acts as a final state interaction. The final state is described by an optical model S-matrix so that both resonant and non resonant states of any continuum energy can be studied as well as deeply bound initial states. It turns out that due to the coupling between the initial and final states, the neutron-core free particle phase shifts are modified, in the exit channel, by an additional phase. Some typical numerical calculations for the relevant observables are presented and compared to experimental data. It is suggest that the excitation energy spectra of an unbound nucleus might reflect the structure of the parent nucleus from whose fragmentation they are obtained.

description: Interface properties of a three-component Bose-Einstein condensate, in which component 3 is sandwiched by components 1 and 2 at the interface, are investigated. It is shown that component 3 can serve as a surfactant: the net interfacial tension is reduced by the presence of component 3. We calculate the interfacial tension as a function of the interaction coefficients. The stability of the interface is studied by Bogoliubov analysis. When the interfacial tension has a spatial gradient, interfacial flow is induced, which resembles the Marangoni flow.

description: We consider relativistic many-particle operators which - according to Brown and Ravenhall - describe the electronic states of heavy atoms. Their ground state energy is investigated in the limit of large nuclear charge and velocity of light. We show that the leading quasi-classical behavior given by the Thomas-Fermi theory is raised by a subleading correction, the Scott correction. Our result is valid for the maximal range of coupling constants, including the critical one. As a technical tool, a Sobolev-Gagliardo-Nirenberg-type inequality is established for the critical atomic Brown-Ravenhall operator. Moreover, we prove sharp upper and lower bound on the eigenvalues of the hydrogenic Brown-Ravenhall operator up to and including the critical coupling constant.
