description: This thesis describes the development of a pinned composite material which possesses spatially varying through-thickness thermal conductivity.  When a constant temperature distribution is applied to one surface, a range of temperatures can be obtained on the opposing surface.  One perceived market for this material is the pharmaceutical drug development process where it is desirable to run many in vitro s at varying temperatures simultaneously. This led to a multi-pronged iterative design process which consisted of numerical simulation, specimen fabrication, and experimental prototype testing.  Numerical simulation identified three pin arrangements of interest:  clusters, a 1D linear gradient, and a 2D linear gradient of pins.  Further simulation focused on a 1D gradient of pins and specific candidate base and pin materials.  Two different manufacturing processes which utilized a special-purpose 3-axis CNC machine were evaluated.  The first batch process inserts pin nails using a commercial pin nailer whereas the second continuous process inserts spooled wire.  In experimental tests, prototypes were fabricated using the batch process.  For example, a 4°C change in temperature across the length of the test specimen was achievable.  However, agreement between experimental and numerical results was imperfect.  The thermal response of the prototypes was generally consistent with expectations except that the top surface was 10-15°C cooler than expected.  Follow-up analysis suggested this was due to several effects including probe quenching (approximately 4°C) and manufacturing process variation (up to 8°C) amongst other effects.  The thesis concludes by identifying a number of desirable modifications in experimental protocol that will address these issues

description: Walking with my mother in front of our apartment building on Saturday, we can see our laundry and everyone else's hanging on balconies to dry.  My mother is so proud that our white laundry is the whitest and cleanest-looking of all. This makes her day. My most persistent memories of my mother are of her washing me as a child, cleaning the house, washing clothes and cooking.  In my M.F.A. exhibition, I investigate issues of cleanliness and purity related to being my mother's daughter, the memories created by my relationship with her, and the parallel relationship that I have with my motherland, Moldova, which I left in 2001.  At the same time, I explore the relationship between memory and performance, my medium of choice for examining the issues above. Being a Moldovan and being my mother's daughter have proven to be critical to my development as an individual and as a woman, and I am not sure I can run away from those facts.  Memories of my mother and my country live through my body.  They emerge in everyday tasks, such as giving my son a bath, cleaning, and washing clothes. Even though I am not consciously seeking to unearth memories, they nonetheless come out through my body and the actions I perform. My body is the present of my memories, and every action that I take makes everything in the past that I have tried to bury resurface.  For this reason, performance is the perfect medium for exploring these issues.

description: Let $E$ be an elliptic curve over an imaginary quadratic field $K$, and $p$ be an odd prime such that the residual representation $E[p]$ is reducible. The $μ$-invariant of the fine Selmer group of $E$ over the anticyclotomic $\mathbb{Z}_p$-extension of $K$ is studied. We do not impose the Heegner hypothesis on $E$, thus allowing certain primes of bad reduction to decompose infinitely in the anticyclotomic $\mathbb{Z}_p$-extension. It is shown that the fine $μ$-invariant vanishes if certain explicit conditions are satisfied. Further, a partial converse is proven.

description: We study the transverse-momentum distribution of hadrons produced in semi-inclusive deep-inelastic scattering. We consider cross sections for various combinations of the polarizations of the initial lepton and nucleon or the produced hadron, for which we perform the resummation of large double-logarithmic perturbative corrections arising at small transverse momentum. We present phenomenological results for the process $ep\to eπX$ for the typical kinematics in the COMPASS experiment. We discuss the impact of the perturbative resummation and of estimated non-perturbative contributions on the corresponding cross sections and their spin asymmetry.

description: We propose a compartmental mathematical model for the spread of the COVID-19 disease, showing its usefulness with respect to the pandemic in Portugal, from the first recorded case in the country till the end of the three states of emergency. New results include the compartmental model, described by a system of seven ordinary differential equations; proof of positivity and boundedness of solutions; investigation of equilibrium points and their stability analysis; computation of the basic reproduction number; and numerical simulations with official real data from the Portuguese health authorities. Besides completely new, the proposed model allows to describe quite well the spread of COVID-19 in Portugal, fitting simultaneously not only the number of active infected individuals but also the number of hospitalized individuals, respectively with a $L^2$ error of $9.2152e-04$ and $1.6136e-04$ with respect to the initial population. Such results are very important, from a practical point of view, and far from trivial from a mathematical perspective. Moreover, the obtained value for the basic reproduction number is in agreement with the one given by the Portuguese authorities at the end of the emergency states.

description: A circulating current can be induced in the Fermi sea by displacing a scatterer, or more generally by integrating a quantum pump into a closed circuit. The induced current may have either the same or the opposite sense with respect to the "pushing" direction of the pump. We work out explicit expressions for the associated geometric conductance using the Kubo-Dirac monopoles picture, and illuminate the connection with the theory of adiabatic passage in multiple path geometry.

description: We develop an improved mass tracer for clusters of galaxies from optically observed parameters, and calibrate the mass relation using weak gravitational lensing measurements. We employ a sample of ~ 13,000 optically-selected clusters from the Sloan Digital Sky Survey (SDSS) maxBCG catalog, with photometric redshifts in the range 0.1-0.3. The optical tracers we consider are cluster richness, cluster luminosity, luminosity of the brightest cluster galaxy (BCG), and combinations of these parameters. We measure the weak lensing signal around stacked clusters as a function of the various tracers, and use it to determine the tracer with the least amount of scatter. We further use the weak lensing data to calibrate the mass normalization. We find that the best mass estimator for massive clusters is a combination of cluster richness, N_{200}, and the luminosity of the brightest cluster galaxy, L_{BCG}: M_{200\barρ} = (1.27 +/- 0.08) (N_{200}/20)^{1.20 +/- 0.09} (L_{BCG}/\bar{L}_{BCG}(N_{200}))^{0.71 +/- 0.14} \times 10^{14} h^{-1} M_sun, where $\bar{L}_{BCG}(N_{200})$ is the observed mean BCG luminosity at a given richness. This improved mass tracer will enable the use of galaxy clusters as a more powerful tool for constraining cosmological parameters.

description: Using the state-of-the-art SKA precursor, the MeerKAT radio telescope, we explore the limits to precision pulsar timing of millisecond pulsars achievable due to pulse stochasticity (jitter). We report new jitter measurements in 15 of the 29 pulsars in our sample and find that the levels of jitter can vary dramatically between them. For some, like the 2.2~ms pulsar PSR J2241--5236, we measure an implied jitter of just $\sim$ 4~ns/hr, while others like the 3.9~ms PSR J0636--3044 are limited to $\sim$ 100 ns/hr. While it is well known that jitter plays a central role to limiting the precision measurements of arrival times for high signal-to-noise ratio observations, its role in the measurement of dispersion measure (DM) has not been reported, particularly in broad-band observations. Using the exceptional sensitivity of MeerKAT, we explored this on the bright millisecond pulsar PSR J0437--4715 by exploring the DM of literally every pulse. We found that the derived single pulse DMs vary by typically 0.0085 cm$^{-3}$ pc from the mean, and that the best DM estimate is limited by the differential pulse jitter across the band. We postulate that all millisecond pulsars will have their own limit on DM precision which can only be overcome with longer integrations. Using high-time resolution filterbank data of 9 $μ$s, we also present a statistical analysis of single pulse phenomenology. Finally, we discuss optimization strategies for the MeerKAT pulsar timing program and its role in the context of the International Pulsar Timing Array (IPTA).

description: In this paper, we study a model of directed polymers in random environment, where the environment is restricted to a time-space tube whose spatial width grows polynomially with time. It can be viewed as an interpolation between the disordered pinning model and the classic directed polymer model. We prove weak coupling limits for the directed polymer partition functions in such tube environments in all dimensions, as the inverse temperature vanishes at a suitable rate. As the tube width varies, transitions between regimes of disorder irrelevance, marginal relevance and disorder relevance are observed.

description: Mental health promotion is an umbrella term that covers a variety of strategies, all aimed at increasing internal capacity or having a positive effect on mental health. In praxis, the encouragement of individual skills and resources for improvements in the socioeconomic environment are leading among them. But, defined by WHO in 1998 health promotion is action and advocacy to address the full range of potentially modifiable determinants of health. That means that mental health promotion requires multisectoral action, involving a number of government sectors such as health, education, employment/industry, environment, transport and social and community services as well as non-governmental or communitybased organizations such as health support groups, churches, clubs and other bodies.

description: The little hierarchy between the GUT scale and the string scale may give us some hints that can be tested at the LHC. To achieve string-scale gauge coupling unification, we introduce additional vector-like particles. We require that these vector-like particles be standard, form complete GUT multiplets, and have masses around the TeV scale or close to the string scale. Interestingly, only the flipped SU(5) x U(1)_X models can work elegantly. We consider all possible sets of vector-like particles with masses around the TeV scale. And we introduce vector-like particles with masses close to the string scale which can mimic the string-scale threshold corrections. We emphasize that all of these vector-like particles can be obtained in the interesting flipped SU(5) x U(1)_X string models from the four-dimensional free fermionic string construction. Assuming the low-energy supersymmetry, high-scale supersymmetry, and split supersymmetry, we show that the string-scale gauge coupling unification can indeed be achieved in the flipped SU(5) x U(1)_X models. These models can be tested at the LHC by observing simple sets of vector-like particles at the TeV scale. Moreover, we discuss a simple flipped SU(5) x U(1)_X model with string-scale gauge coupling unification and high-scale supersymmetry by introducing only one pair of the vector-like particles at the TeV scale, and we predict the corresponding Higgs boson masses. Also, we briefly comment on the string-scale gauge coupling unification in the model with low-energy supersymmetry by introducing only one pair of the vector-like particles at the intermediate scale. And we briefly comment on the mixings among the SM fermions and the corresponding extra vector-like particles.

description: The objective of this paper is twofold. First, we analyze farmers’ perceptions of various risk sources. Second, we identify socio-demographic characteristics of the farmers that affect their risk perceptions. The data were collected using a structured questionnaire administered to a sample of 931 farmers distributed between different regions of Tunisia (Central and Northwestern). The data were analyzed using principal component analysis, cluster analysis, and a bivariate probit model. We identify two components out of nine risk sources: socio-economic and natural risks. The estimation results of the bivariate probit model reveal that rainfed farming, agriculture as main activity, young age, not being assisted from extension services, and being a female farmer are significantly and positively related to higher perceived risk levels. Location is only significant for the socio-economic component risk. We therefore suggest that there is a need of targeted risk management strategies for different categories of farmers in order to reduce risk and enhance the efficiency of agriculture in Tunisia.

description: We propose a Fourier projection algorithm and demonstrate its superiority for calculation of the phonon dispersion relations of 2D and 3D crystals based on the atomic coordinate trajectories from supercell molecular dynamics/first-principle molecular dynamics simulations. The lattice vibration states are described in a six-dimensional phase space composed of lattice and wave vectors. Phonon dispersion information in the first Brillouin zone sampled with a k-mesh grid of N×N×N is generated by Fourier projection of the lattice vibration frequencies in the supercell by N×N×N primitive cells, the dispersion relations along high-symmetry paths are retrieved therefrom. Our algorithm is physically intuitive, computationally convenient, and universally applicable. As examples of application, the successful dispersion relation calculations of 2D graphene, 3D BCC-Fe and FCC-Cu are presented. This algorithm shows the correspondence between real and reciprocal lattices, that is, the spatial information in the states of the lattice vibration were preserved. The high-symmetry paths of the first Brillouin zone in the reciprocal lattice primitive cells of the hexagonal, BCC, and FCC lattice were also given in detail. In combination with first-principles molecular dynamics, as long as the interatomic force is accurately known, reliable and accurate dispersion relation can be achieved by this Fourier projection algorithm.

description: Contexte : il y a 1'500 nouvelles lésions médullaires par année en France, et les douleurs neuropathiques concernent 40 à 70% d’entre elles. La prise en charge actuelle est principalement médicamenteuse. Objectif : évaluer l’efficacité de la réalité virtuelle sur l’intensité des douleurs neuropathiques des lésés médullaires. Méthodologie : la population est composée de lésés médullaires de stade AIS A à D et ayant des douleurs neuropathiques chroniques. Les études doivent utiliser un protocole de réalité virtuelle, évaluer l’intensité des douleurs par l’échelle NRS et être écrit en anglais. Les recherches ont été faites sur PubMed, Cochrane Library et PEDro jusqu’en janvier 2019. Résultats : cette revue inclut quatre articles pour un total de 83 patients. Trois de ces études évaluent l’efficacité de la marche virtuelle par l’intermédiaire de la réalité virtuelle immersive (RVI) ou semi-immersive et la dernière propose des jeux à travers la réalité virtuelle augmentée (RVA). Les études ont toutes mis en évidence une diminution des douleurs, bien que seules deux montrent des résultats significatifs. Les limites principales sont le faible nombre de participants ainsi que la qualité des articles. Conclusion : la réalité virtuelle est une option thérapeutique intéressante pour diminuer ce type de douleurs à court terme, par le processus de la distraction. La neuroplasticité est, quant à elle, le processus de choix pour obtenir une diminution des douleurs à long terme. Il semble que l’association de la réalité virtuelle à d’autres thérapies favorise le deuxième processus et permette des résultats sur le long terme.
Separate stages : la traduction du theatre dans le contexte Canada/Quebec

description: L'etude suivante porte sur la traduction du theatre dans le contexte Canada/Quebec, de 1951 a 1994, et suit une methodologie empruntee a l'Ecole de Tel-Aviv et a l a «critique productive» d'Antoine Berman. Apres un survol des discours portant sur les litteratures et les dramaturgies canadienne et quebecoise en traduction, une analyse des douze pieces inscrites au corpus permet d ' identifier la fonction attribuee au traduit dans le contexte recepteur. De la fin des annees 60 jusqu'au milieu des annees 80, les dramaturgies franco-quebecoise et canadienne-anglaise sont marquees par la question identitaire . La traduction repond alors a un desir de creer un repertoire national, specifiquement quebecois d'une part et specifiquement canadien de l'autre. Cette specificite repose sur la mise en valeur de la difference, ressentie comme essentielle a L'elaboration d'une identite nationale distincte. Commune a chaque groupe linguistique, cette mise en valeur de la difference fait toutefois appel a des procedes fort divergents. D'un cote, la traduction franco-quebecoise met l'accent sur sa propre difference, au moyen d'adaptations qui prennent l'apparence d'un produit local et masquent l'origine du texte canadien-anglais. De l'autre, la traduction canadienne-anglaise souligne l ' alterite du texte quebecois en insistant sur son caractere non menacant et evite la cruciale question de la representation anglaise du joual, langue emblematique du nouveau theatre quebecois. A la fin des annees 80, les deux groupes linguistiques rorapent avec ce modele et affichent de nouvelles tendances. Au Quebec, ou le theatre canadien-anglais connait une popularity grandissante depuis 1990, l'obligation speculaire cede le pas au spectaculaire oblige et a la theatralite provocante qui servent a legitimer l'emprunt anglo-canadien. De son cote, la traduction anglaise du texte quebecois n'est plus confronted au joual mais au probleme que pose l'esthetique verbale hautement stylisee des pieces franco-quebecoises plus recentes. La traduction doit alors attenuer une exuberance langagiere qui heurte les normes en vigueur dans la dramaturgie canadienne-anglaise. La forte polarisation observee dans les strategies de traduction deployees de part et d'autre reflete l'asymetrie des positions occupees par les dramaturgies produites dans les langues officielles du Canada, ou l'anglais constitue la langue de la majorite et ou le francais demeure minoritaire.

description: This poster was presented at the RDM Trainer Network Meeting. The session was planned to foster exchange regarding perspectives on “the job” and offered the chance to show how and with which methods RDM can be taught.

As part of the collaborative project "Institutionalized and sustainable Research Data Management in Brandenburg" (IN-FDM-BB, https://fdm-bb.de/), we designed a certificate course for Master students in Brandenburg. The course was conducted as a week-long Online-Spring School, was free of charge, and took place for the first time during the semester break in March 2023. These choices were made to remove location-based or financial obstacles and ensure maximal accessibility to all students. We did, however, limit the maximum number of participants to 30. This was done to encourage exchange and discussion in smaller groups and to allow for sufficient support by the lecturers. Lecturers from the University of Applied Sciences Potsdam, the University of Potsdam and the Brandenburg University of Technology Cottbus-Senftenberg focused on the following topics: an interdisciplinary introduction to RDM, metadata, data management plans, technical research data infrastructures and tools, publication and legal aspects of research data, good scientific practice and project management. Certificate courses for researchers or research support staff are currently being planned. In this poster session, we would like to share the lessons learned from our first Spring School, and – in the collaborative spirit of IN-FDM-BB – would happily exchange collaboration ideas beyond Brandenburg.

description: Aspect Oriented Software Development (AOSD) is a promising methodology which provides powerful techniques to improve the modularity of the software by separating the cross-cutting concerns from the core functionality. Since evolution is a major requirement for the sustainability of any software, it is necessary to quantitatively measure its impact. In order to quantify, it is essential to define metrics that will capture the evolution of Aspect Oriented (AO) software. It is also necessary to compare the metric values of various versions of software to draw inferences on the evolution dynamics of AO software. This needs identification of artifacts that were added, deleted or modified across versions and study the consequence of these types of changes. This paper defines a new set of metrics for measuring the evolution of Aspect Oriented software. As a case study, an aspect refactored software, AJHotDraw has been chosen and its four versions have been analyzed for their capability to evolve over time.

description: In the Land of Milk and Honey and No Return, the two films I made for the MFA thesis show, are discussed here.  Milk and Honey uses experimental montage to explore the themes of escape and illusionism. No Return uses experimental montage to weave together three strands of images that evoke a concern for the natural world, its loss, and the desire to return to the natural world. The main characters in the films desire an intimate connection with the natural world.  Their desires and anxieties are expressed as anti-civilization fantasies.  The characters' actions take the form of escapist and activist activities such as attempts to fly and self-burial.  These actions are considered ascending and descending actions, which are explored and analyzed. The characters use magic and imagination in their attempt to flee to dreamlike paradises.  Three main symbols arose in the films: the bird-people, the shovel and the fence. These three emblems all have to do with the nature of my human relationship to the natural world.

description: We show how Rio's method [Probab. Theory Related Fields 104 (1996) 255--282] can be adapted to establish a rate of convergence in ${\frac{1}{\sqrt{n}}}$ in the multidimensional central limit theorem for some stationary processes in the sense of the Kantorovich metric. We give two applications of this general result: in the case of the Knudsen gas and in the case of the Sinai billiard.

description: The proponents of Aspect Oriented Software Development (AOSD) methodology have done a tremendous amount of work to bring out the positive effects of its adoption using quantitative assessment. A structured assessment of the methodology requires a well-defined quality model. In this paper, an AI agent based quality model has been proposed to evaluate the effect of aspectization. The model has been applied on already existing and equivalent versions of object oriented and aspect oriented case study application, university automation software. Specific metrics for the software design properties have been measured using AI agents for the different versions and were used to infer upon the effect on quality. Based on the initial measurement, it was found that aspectization has positively improved all the three quality attributes defined in the quality model. The attributes of evolution and reusability showed significant improvement in quality due to the effect of aspectization.

description: In Defense of Native Soil is an exhibition that questions specific dichotomies  or paradoxes to create ambiguous answers to issues of the suburban environment, the  character and power of the artist, and the use of the gallery and the art object as a tool  for social change. The thesis exhibition features dandelions and the remnants of  elaborate processes that are futile or ridiculous, metaphoric, and temporary. These  remnants, when installed in the gallery aim to embrace ephemeral moments, like  childhood wishing on a dandelion, thus examining the elusive core of our fraught  relationship with and legacy of the suburban front yard. My work investigates the  consequences and cyclical nature of human interactions with the lawn as the face of  the American dream, and the potential of agency in the art object to influence that  circumscribed and very established routine.  These works are an attempt to control the uncontrollable. They establish a  metaphor regarding cultural and social understandings of the lawn through the use of  the commonplace and seemingly benign dandelion. In the thesis, the dandelion is  used as an object that is at once subversive, but contains potential proactivity – it is  simultaneously humble and monumentalized. These inherent dichotomies are  strategically emphasized to symbolically dissect the absurdity and fragility of our  received suburban values.

description: I Want to Be: Perceiving Identity hemed around the importance of self-identity in the complex dynamics of our social structure. Even at a young age the idea of identity is prevalent as we are often asked, What do you want to be when you grow up? Who are we? Where do we come from? As curious creatures, we continue to plunge into mysteries, finding definitive answers to these universal questions. To Ren Magritte, The mind loves the unknown. It loves images whose meaning is unknown, since the meaning of the mind itself is unknown. Accompanying I Want to Be: Perceiving Identity  short film surrounding the idea of self-identity, or, lack thereof. Entitling The Son of Many  film chronicles the direction an individual without an identity might take.
title: Judgment of Bad Character Distinguishes Moral Disgust from Anger

description: Moral violations often evoke disgust. While it has been consistently shown that disgust is a predominant emotion in response to bodily purity violations, its role in sociomoral violations, in which pathogen content or misuse of the body is not involved, is still debated. Inspired by Giner-Sorolla & Chapman (2017) who suggested that disgust is more closely associated with judgment of bad moral character than anger, whereas anger is more closely associated with judgment of harmful acts and consequences than disgust, the current research further examined this hypothesis from three different angles. Drawing on the research literature on dark personalities, Experiments 1 to 3 (Ns = 191, 180, 157) used non-harmful behavioural signals of sadism, narcissism, and Machiavellianism, respectively, to manipulate agents' bad moral character in vignettes, and found that disgust (vs. anger) responded more sensitively to bad moral character, whereas anger (vs. disgust) responded more sensitively to harm. Experiments 4 and 5 (Ns = 146, 186) tested whether framing moral offences to highlight either the agents' bad character or harm they caused increases disgust or anger. Results showed that the framing had limited influences on people's emotional responses. Experiment 6 (N = 224) showed that expressions of disgust (vs. anger) more strongly signal to third-party observers that the target of the emotion has bad moral character. The results shed light on the difference between the two often intertwined moral emotions and the distinct function of disgust in marking individuals with bad moral character independently of harmful consequences of their actions.
I Have Disappeared To You: Live and Mediated Presence in Performance

description: The aim of this thesis is to examine performance through my personal experience as a dancer who has incorporated video technology into my movement practice. To place these ideas in a wider context, I look at the intersection of visual art and dance performance, drawing on a range of theorists from both traditions. This discussion is divided into two groupings of ideas. First, I examine empathy and embodiment through the work of Susan Foster and Amelia Jones. Secondly, I consider media and memory through the work of Peggy Phelan, Philip Auslander and Andr? Lepecki. In I Will Disappear to You, I intertwined live and mediated presence through a constructed space that alternated between being a container for individual performances and an installation presenting the video documentation of these encounters. I constructed this space as an ideal place to develop a life and embodied presence that connects with others and subsequently presents the incomplete memory of those encounters through video. I examine where this artwork fits in within an art historical context by presenting a personal narrative of experiences with works that address embodiment as the site of artistic creation and perception. And finally, I conclude with a reflection on performance re-appearing as rumor and a discussion of the challenges and opportunities for visual artists and dance artists to learn from each other.

description: Using the factorization approach of quantum mechanics, we obtain a family of isospectral scalar potentials for power law inflationary cosmology. The construction is based on a scattering Wheeler-DeWitt solution. These iso-spectrals have new features, they give a mechanism to end inflation, as well as the possibility to have new inflationary epochs. The procedure can be extended to other cosmological models.

Perils of Embedding for Quantum Sampling

description: Given quantum hardware that enables sampling from a family of natively implemented Hamiltonians, how well can one use that hardware to sample from a Hamiltonian outside that family? A common approach is to minor embed the desired Hamiltonian in a native Hamiltonian. In Phys. Rev. Research 2, 023020 (2020) it was shown that minor embedding can be detrimental for classical thermal sampling. Here, we generalize these results by considering quantum thermal sampling in the transverse-field Ising model, i.e. sampling a Hamiltonian with non-zero off diagonal terms. To study these systems numerically we introduce a modification to standard cluster update quantum Monte-Carlo (QMC) techniques, which allows us to much more efficiently obtain thermal samples of an embedded Hamiltonian, enabling us to simulate systems of much larger sizes and larger transverse-field strengths than would otherwise be possible. Our numerics focus on models that can be implemented on current quantum devices using planar two-dimensional lattices, which exhibit finite-temperature quantum phase transitions. Our results include: i) An estimate on the probability to sample the logical subspace directly as a function of transverse-field, temperature, and total system size, which agrees with QMC simulations. ii) We show that typically measured observables (diagonal energy and magnetization) are biased by the embedding process, in the regime of intermediate transverse field strength, meaning that the extracted values are not the same as in the native model. iii) By considering individual embedding realizations akin to 'realizations of disorder', we provide numerical evidence suggesting that as the embedding size is increased, the critical point shifts to increasingly large values of the transverse-field.

The rp-Process in Neutrino-driven Winds

description: Recent hydrodynamic simulations of core-collapse supernovae with accurate neutrino transport suggest that the bulk of the early neutrino-heated ejecta is proton rich, in which the production of some interesting proton-rich nuclei is expected. As suggested in recent nucleosynthesis studies, the rapid proton-capture (rp) process takes place in such proton-rich environments by bypassing the waiting point nuclei with the beta-lives of a few minutes via the faster capture of neutrons continuously supplied from the neutrino absorption by protons. In this study, the nucleosynthesis calculations are performed with the wide ranges of the neutrino luminosities and the electron fractions (Ye), using the semi-analytic models of proto-neutron star winds. The masses of proto-neutron stars are taken to be 1.4 Msolar and 2.0 Msolar, where the latter is regarded as the test for somewhat high entropy winds (about a factor of two). For Ye > 0.52, the neutrino-induced rp-process takes place in many wind trajectories, and the p-nuclei up to A ~ 130 are synthesized with interesting amounts. However, 92Mo is somewhat underproduced compared to those with similar mass numbers. For 0.46 < Ye < 0.49, on the other hand, 92Mo is significantly enhanced by the nuclear flows in the vicinity of the abundant 90Zr that originates from the alpha-process at higher temperature. The nucleosynthetic yields are averaged over the ejected masses of winds, and further the Ye distribution predicted by the recent hydrodynamic simulation of a core-collapse supernova. Comparison of the mass-Ye-averaged yields to the solar compositions implies that the neutrino-driven winds can be potentially the origin of light p-nuclei up to A ~ 110, including 92,94Mo and 96,98Ru that cannot be explained by other astrophysical sites.
