description: A functional method is discussed, where the quantum fluctuations of a theory are controlled by a mass parameter and the evolution of the theory with this parameter is connected to its renormalization. It is found, in the framework of the gradient expansion, that the coupling constant of a N=1 Wess-Zumino theory in 2+1 dimensions does not get quantum corrections.

description: A high-resolution HST/STIS spectrum (R=30,000) is presented of the three MgII-selected absorption systems (A, B, and C, clustered within 1500km/s) at z~0.93 toward the quasar PG 1206+459. A WIYN Gunn i-band image of the quasar field and spectroscopy of two galaxy candidates are also presented. A multi-phase medium is seen in all three systems, consistent with smaller, denser clouds producing low-ionization transitions (MgII, FeII, and SiII) and larger, diffuse clouds giving rise to high-ionization transitions (CIV, NV, and/or OVI). (1) System A, a multi-cloud, weak MgII absorber at z=0.9254, requires a super-solar metallicity in both low- and high-ionization phases, unless an alpha-group enhancement is included. With the unusually complex velocity structure resolved in the NV profiles, this system is unlikely to represent a traditional galaxy disk/corona. The most likely candidate host galaxy is a ~2L^*, apparently warped, spiral at an impact parameter of 43h^-1 kpc. (2) System B, at z=0.9276, has the strongest MgII absorption and has an approximately solar metallicity in the low-ionization phase. The smooth, broad high-ionization profiles may indicate a coronal structure similar to that of the Milky Way. The redshift of an L^* galaxy (z=0.9289), at an impact parameter of 38h^-1 kpc is consistent with the redshift of this system. (3) System C, at z=0.9342, has a single component in MgII, separated from the other two systems by ~1000km/s. It lacks the small, low-ionization cloud characteristic of an isolated single-cloud, weak MgII absorber. Its absorption properties are similar to the ``satellite clouds'' of classic strong MgII absorbers, so this could be a high-velocity cloud in the galaxy group responsible for the systems, possibly related to a 0.2L^* galaxy at an impact parameter of 43h^-1 kpc.

description: In this paper we present a sequential hypothesis test for the detection of general jump size distrubution. Infinitesimal generators for the corresponding log-likelihood ratios are presented and analyzed. Bounds for infinitesimal generators in terms of super-solutions and sub-solutions are computed. This is shown to be implementable in relation to various classification problems for a crude oil price data set. Machine and deep learning algorithms are implemented to extract a specific deterministic component from the crude oil data set, and the deterministic component is implemented to improve the Barndorff-Nielsen and Shephard model, a commonly used stochastic model for derivative and commodity market analysis.

REFRAME: to express differently; a look at reframing Frame Lake in Yellowknife, NT
Creators: name: Neudorf, Julianna
Publisher: name: The University of British Columbia
Year: 2023

description: This graduate project examines the revitalization of Frame Lake in Yellowknife, Northwest Territories through the creative and critical lens of landscape architecture. The lake, located centrally within the city, has long been contaminated with arsenic and other pollutants, in large part due to its proximity to abandoned gold mines. The contamination of the lake has resulted in it being unsafe for activities such as fishing, swimming, wading, and berry and plant picking. The project will investigate the history of Yellowknife and potential of phytoremediation, a process that utilizes plants to clean up a contaminated environment, as a solution for restoring the ecological integrity and life of the lake to its past provision and future potential for both human and non-human use. The project will also consider the values of and cultural significance to local residents and the Yellowknives Dene. Through this examination, the project aims to not only remediate the lake but also to reframe the way we understand and value ecological assets in the north. A phased approach was taken to implement the design of the public spaces around the lake. This was done to ensure both people and native wildlife will be able to enjoy Frame Lake throughout the project implementation. Phase zero is ongoing with seasonal infrastructure employed during the long winter months in Yellowknife when Frame Lake is frozen. Phase one will occur from years 0-5, phase two from years 5-15, and phase three after 15 years of remediation when Arsenic levels should be lowered substantially, and people can once again use Frame Lake for water-based activities.
The role of performance in aural harmony : discovering, classifying, and evaluating pedagogical approaches

subject: Harmony Instruction and study

description: Harmony is a fundamental topic that pervades much of tertiary-level aural training. Many activities in aural harmony that are described in the literature, however, represent idiosyncratic prescriptions of set exercises (e.g., harmonic dictation). No researcher has previously attempted to systematically compare a broad range of pedagogical approaches in aural harmony. Furthermore, despite the critical role of performance in music education, there is little understanding of how and why students engage in performance and other actions during aural harmony activities. The primary aim of this dissertation is to investigate the multitude of pedagogical approaches within the subject of aural harmony. This is achieved through the discovery, classification, and evaluation of pedagogical approaches as revealed through class observations and discussions with teachers at ten tertiary institutions in four countries (Japan, the US, Sweden, and Norway). Through an extensive examination of this data, I identify 89 aural harmony activities (Chapter 2). My analysis of these activities results in the creation of a classification system (Chapter 3). There are four categories in this classification system. Each category represents a type of action sequence, which in turn represents one action leading to another action. The four categories thus indicate fundamentally different learning outcomes. I classify each of the 89 collected activities under one or more categories, which enables me to systematically compare the pedagogical approaches within each of the four categories of activities (Chapters 4-6). The secondary aim of this dissertation is to report my experiences of applying the insight and knowledge gained from the above analyses to my own teaching within an Australian tertiary music institution (Chapter 7). Following an explanation of my particular educational context, I describe the process of devising, developing, and implementing five activities. Of these activities, one uniquely enables students to simulate performance actions through gestures. I evaluate these activities based on student feedback as well as my self-reflection. This research has resulted in detailed descriptions of a considerable range of aural harmony activities (Appendix A). My analyses of these activities reveal a range of pedagogical approaches that can maximise our students' acquisition of aural skills. I argue that while student performance is valuable in much of aural training, there are alternative means of engaging students that can also result in favourable learning experiences. This dissertation concludes with a consideration of the applicability of two of the activities presented in Chapter 7, as well as the classification system proposed in Chapter 3, across other areas of aural skills pedagogy.
Boys' love in girls' hands : the survival of a gendered youth culture in mainland China and Hong Kong

description: Originating in the late-1970s' Japanese comic and fiction culture, boys' love (BL) has become a transnational genre in which young women create, distribute and appreciate stories of male-male relationships in various media, ranging from fiction, comics, music, video films, radio dramas and cosplays (an abbreviation of costume-play), to computer games. Also known as danmei (we indulge in the beautiful) in Chinese, the genre expanded and blossomed in the late-1990s in mainland China and Hong Kong. Grounded in the two relatively unstudied fields, this thesis presents a systematic analysis of a distinctive (and less understood) Chinese BL phenomenon from an ethnographic perspective. Unlike most existing literature which has been focusing on psychoanalysis of BL participation and how followers in different countries accept Japanese BL genre as passive readers, much of this thesis deals with the growing complexity of the production, regulation, representation, consumption, and circulation of local BL practices in mainland China and Hong Kong. It aims to shed lights on how a transnational culture is constructed and indigenised under local social, economic, cultural and political conditions. I argue that young women in mainland China and Hong Kong turn from a passive readership to become active in local BL production through ways such as appreciating and identifying with BL values, participating in creation of the most convenient amateur cultural forms, establishing local BL economies, and using conditional and responding tactics to survive the hostile political and social circumstance. In a weaker status position and a more hostile social circumstance, Chinese participants have to poach resources from the cultural industry and transform their resistance into everyday tactics more actively than their Hong Kong counterparts.

description: We investigate the phenomenological aspects of non-perturbative baryon- and lepton-number-violating processes at hadron colliders. Such processes, induced by instanton/sphaleron configurations of the electroweak gauge fields, are believed to play a crucial role in the generation of baryon asymmetry in the early Universe at finite temperature. On the other hand, at colliders (that represent the zero-temperature high-energy regime) the rate and observability of such processes are still under debate. Motivated by current theoretical considerations, we construct a modern event generator within the general-purpose Herwig Monte Carlo framework, that aims to capture the most relevant features of the dominant processes. We perform a detailed phenomenological analysis focussing on the Large Hadron Collider, at 13 TeV proton-proton centre-of-mass energy, a potential high-energy upgrade at 27 TeV and the proposed Future Circular Collider (FCC-hh) at 100 TeV. We derive constraints on the expected rates for various parametrisations of our model. We find that all three colliders are capable of providing meaningful information on the nature of instanton/sphaleron-induced processes at various energy scales.

Presentation 1: DDI's current product line: DDI Codebook, DDI Lifecycle and related products. The Alliance continues to support, develop, and encourage the adoption of these specifications. Presentation 2: Preliminary release of DDI 4, the newest DDI version based on an information model. Slated for a mid-2018 release, this "prototype" is not intended for production but provides an opportunity to test and provide feedback on how DDI 4 describes data capture, data stores, transformation processes, studies, and classification management. Functionality will be presented through use cases. The presentation will highlight the model-driven production framework which generates representations like XML and RDF, and the documentation. Presentation 3: The new strategic plan of the DDI Alliance and the vision of a DDI-based infrastructure for the empirical social sciences. The strategic plan covers the standards (i.e. maintaining multiple lines of specifications), community goals (i.e. engagement with the global digital research infrastructure, and solving common problems with current DDI users), and organizational goals of the DDI Alliance. The infrastructure vision proposes a combination of a curated common data element registry with a portal of existing DDI metadata repositories.
Exact noncommutative solitons in p-adic strings and BSFT

description: The tachyon field of p-adic string theory is made noncommutative by replacing ordinary products with noncommutative products in its exact effective action. The same is done for the boundary string field theory, treated as the p -> 1 limit of the p-adic string. Solitonic lumps corresponding to D-branes are obtained for all values of the noncommutative parameter theta. This is in contrast to usual scalar field theories in which the noncommutative solitons do not persist below a critical value of theta. As theta varies from zero to infinity, the solution interpolates smoothly between the soliton of the p-adic theory (respectively BSFT) to the noncommutative soliton.

description: A cascaded iterative Fourier transform (CIFT) algorithm is presented for optical security applications. Two phase-masks are designed and located in the input and the Fourier domains of a 4-f correlator respectively, in order to implement the optical encryption or authenticity verification. Compared with previous methods, the proposed algorithm employs an improved searching strategy: modifying the phase-distributions of both masks synchronously as well as enlarging the searching space. Computer simulations show that the algorithm results in much faster convergence and better image quality for the recovered image. Each of these masks is assigned to different person. Therefore, the decrypted image can be obtained only when all these masks are under authorization. This key-assignment strategy may reduce the risk of being intruded.

Putting the CURATE model in practice: Training for data curation
Creators: name: Kozlowski, Wendy

Publisher: name: Zenodo

description: In order for data to be fully publicly accessible to search, retrieve, and analyze, most data require specialized curatorial treatments. Supporting researchers with data curation is an important role that information specialists aspire to fill as the workforce transforms to assume greater digital stewardship responsibilities. Information specialists are experts at identifying, selecting, organizing, describing, preserving, and providing access to information materials, print and digital. Yet, the results of our recent Association of Research Libraries SPEC Kit indicate that staffing and training for data curators is the biggest challenge facing institutions in the next 3-5 years. To address this need the Data Curation Network (DCN), in collaboration with IASSIST, held a one-and-a-half day data curation training event in December 2017 aimed at instructing a wide range of information specialists in the DCN CURATE method. This method sets a foundation for curation treatments that many individuals can build upon in order to appropriately curate research data at their institution. Panelists will report on this training event, highlighting the curriculum, participant curation treatment adoption post-workshop, and lessons learned.

description: Developing CPS is challenging: Cross-domain collaboration and cross-generational design pose fincancial risks for manufacturers, as different engineering models can become inconsistent to each other in the development process. Existing apporaches fail to ensure consistency within and across system generations. Our research addresses this issue by combining mechanical and software engineering approaches. We present a methodology using a brake system research platform to identify challenges and solutions in CPS development. The objective of our research is to formalize changes between generations of CPS and to develop algorithm-based consistency analysis methods. In the long term, we aim to facilitate cross-domain consistency management and create a systematic framework for CPS development.

description: Many well-known information retrieval models rank documents using scores derived from the query and document text. Some other models integrate query-independent evidence, such as indegree or URL structure, typically as prior probabilities. This thesis proposes a model based on a third category of evidence, external textual annotations. The model considers both the degree of match between queries and annotations and the degree of association between annotations and documents. The annotation retrieval model accommodates anchortext as well as additional sources: click-associated queries, folksonomy `tags' and microblogs. The characteristics of these types of annotations and their potential for use in information retrieval are studied. In previous work, annotations have been appended to the document text or treated as a field of the document. A new index structure, designed to support the efficient evaluation of queries with the new model, is evaluated. Secondary storage and query processing resources required for the annotations are reduced while preserving result quality. A useful source of annotations is anchortext, but anchortext can be gathered only after links have been created. Click-associated queries and folksonomy tags also take time to accumulate and may not provide up to the minute evidence. However, microblog posts, by their nature, relate to contemporary events and may provide a good method of finding new documents on the web. A method of collecting and conducting a new-web search system is proposed. The contributions of the thesis are as follows. First, an investigation into the characteristics of the different types of annotations, particularly folksonomy tags and microblogs. Second, a model and investigation of a practical data structure for utilising annotation data in a search system. Third, an evaluation method for real-world retrieval systems. Finally, a method of collecting evidence for new-web search based on annotations. -- provided by Candidate.

description: We investigate the importance of final state interactions in weak nonleptonic hyperon decays within a relativistic chiral unitary approach based on coupled channels. The effective potentials for meson-baryon scattering are derived from a chiral effective Lagrangian and iterated in a Bethe-Salpeter equation, which generates the low lying baryon resonances dynamically. The inclusion of final state interactions decreases the discrepancy between theory and experiment for both s and p waves. Our study indicates that contributions from higher order terms of the weak effective Lagrangian may play an important role in these decays.

Embodied : A Relational Understanding of Carbon as Kin
Creators: name: Dulong, Nicole
Publisher: name: The University of British Columbia
Year: 2023

description: Employed by contemporary lexicons to describe “a malevolent, impending doom of emissions”, the dominant narratives that surround carbon often centre just one molecule, carbon dioxide (Reed 2022). This myopic language of demonization has both distanced and distorted much of humanity's carbon comprehension while retrospectively legitimizing hierarchical individualism, outdated scientific ontologies, and extractive carbon control and marketization tactics. In understanding this, Embodied recognizes the need for a radical transformation in the thought systems that surround carbon consciousness, ultimately suggesting that a relational understanding of carbon as kin is essential to actualizing ethics of care in contemporary design practice and process. Bridging the Traditional Worldviews of Kinship with western epistemological underpinnings of somatic learning, Embodied responds to scholarship emphasizing the critical importance of “connecting disparate ways of knowing, including scientific, artistic, sensuous, and local knowledges” to better understand carbon, relationality, awareness, and engagement (Bentz 2022). It looks to carbon as a muse, a teacher, a shapeshifter, and an architect of life itself, and investigates the various scales, acts, feelings, bodies, makings, insights, and processes that can dream us into carbon reciprocity as carbon-based life forms ourselves.

description: White dwarfs containing orbiting planetesimals or their debris represent crucial benchmarks by which theoretical investigations of post-main-sequence planetary systems may be calibrated. The photometric transit signatures of likely planetary debris in the ZTF J0139+5245 white dwarf system has an orbital period of about 110 days. An asteroid which breaks up to produce this debris may spin itself to destruction through repeated close encounters with the star without entering its Roche radius and without influence from the white dwarf's luminosity. Here, we place coupled constraints on the orbital pericentre ($q$) and the ratio ($β$) of the middle to longest semiaxes of a triaxial asteroid which disrupts outside of this white dwarf's Roche radius ($r_{\rm Roche}$) soon after attaining its 110-day orbit. We find that disruption within tens of years is likely when $β\lesssim 0.6$ and $q\approx 1.0-2.0r_{\rm Roche}$, and when $β\lesssim 0.2$ out to $q\approx 2.5r_{\rm Roche}$. Analysing the longer-timescale disruption of triaxial asteroids around ZTF J0139+5245 is desirable but may require either an analytical approach relying on ergodic theory or novel numerical techniques.

description: We analyze the spectral properties of driven, supersonic compressible magnetohydrodynamic (MHD) turbulence obtained via high-resolution numerical experiments, for application to understanding the dynamics of giant molecular clouds. Via angle-averaged power spectra, we characterize the transfer of energy from the intermediate, driving scales down to smaller dissipative scales, and also present evidence for inverse cascades that achieve modal-equipartition levels on larger spatial scales. Investigating compressive versus shear modes separately, we evaluate their relative total power, and find that as the magnetic field strength decreases, (1) the shear fraction of the total kinetic power decreases, and (2) slopes of power-law fits over the inertial range steepen. To relate to previous work on incompressible MHD turbulence, we present qualitative and quantitative measures of the scale-dependent spectral anisotropy arising from the shear-Alfvén cascade, and show how these vary with changing mean magnetic field strength. Finally, we propose a method for using anisotropy in velocity centroid maps as a diagnostic of the mean magnetic field strength in observed cloud cores.

The appearance of a granular segregation is shown to strongly depend on the sand bed preparation. The initial wavelength of the mixture is measured. In the final steady state, a segregation in volume is observed instead of a segregation at the surface as reported before. The correlation between this phenomenon and the fluid flow is emphasised. Finally, different ``exotic'' patterns and their geophysical implications are presented.

description: Background: Earlier age at menarche (AAM), a marker of puberty timing in females, has been associated with a higher likelihood of adolescent risk-taking behaviours and variably associated with educational attainment. Aim: To examine the association between AAM and educational attainment in the Pelotas, Brazil, 1982 Birth Cohort. Subjects and methods: AAM was categorised as Early (7–11 years), Average (12–13 years), or Late (14+ years). Primary outcome: years of education (age 30). Secondary outcomes: risk-taking behaviours, adult income and school grade failure. Results: In adjusted models, compared to Average AAM, Late AAM was associated with 0.64 fewer years of education (95% CI: −1.15, −0.13). Early AAM was associated with earlier age at first sexual intercourse (−0.25 years; 95% CI: −0.39, −0.12), whereas Late AAM was associated with 17% lower adult income (0.83; 95% CI: 0.71, 0.95) and 0.31 years older age at first alcohol consumption (95% CI: 0.10, 0.52). Conclusions: Our findings confirm the association between earlier puberty timing in females and a greater likelihood of risk-taking behaviours in this setting of recent secular changes towards earlier puberty. However, the association between Late AAM and lower education was surprising and may support a psychosocial rather than biological link between puberty timing and educational outcomes.

description: As reported previously, the U.S. Bureau of Labor Statistics is developing a taxonomy of concepts and terms describing time-series data the agency produces. The taxonomy will be used for:1. User interface for the DataFinder general data dissemination tool 2. Source for terms to tag documents and reports consistent with the data they describe 3. Guide for the redesign of the BLS web site Currently, it is not possible to know if all data concerning some subject were found, and it is difficult to specify and download multiple time series at once. The taxonomy is expected help overcome these limitations. The BLS cognitive laboratory is used to test question wording, systems interfaces, and the look and feel of web sites. Testing for a resource similar to the taxonomy is new. Since December, the development of the taxonomy stopped, and work to test the taxonomy in the cognitive laboratory began. The design of the cognitive testing is described in the paper. Many kinds of tests are possible, but the taxonomy structure limits those to a few. How incorporating the results of the tests will alter the taxonomy is described. Finally, the future for continued taxonomy work is discussed.

description: Ordinary quantum mechanics is formulated on the basis of the existence of an ideal classical clock external to the system under study. This is clearly an idealization. As emphasized originally by Salecker and Wigner and more recently by other authors, there exist limits in nature to how ``classical'' even the best possible clock can be. When one introduces realistic clocks, quantum mechanics ceases to be unitary and a fundamental mechanism of decoherence of quantum states arises. We estimate the rate of universal loss of unitarity using optimal realistic clocks. In particular we observe that the rate is rapid enough to eliminate the black hole information puzzle: all information is lost through the fundamental decoherence before the black hole can evaporate. This improves on a previous calculation we presented with a sub-optimal clock in which only part of the information was lost by the time of evaporation.

description: How could we serve students, teachers and researchers better? What kinds of stories do our users have to tell? What kinds of narratives are told with the data available at the Finnish Social Science Data Archive (FSD)? Data archives support the scientific community in managing the data life cycle in various ways. Data archives are not burial grounds for data. Instead, stories live on in archived data sets. FSD conducted a survey for its users in Fall 2017. The results of the survey will be introduced in the presentation. Respondents included both data depositors and data re-users. Special themes of the survey were communication and the impact of FSD data and services. Some of the questions are similar to what have been previously asked in the user and impact surveys of other data organisations (Arhiv družboslovnih podatkov, European Social Survey, Economic and Social Research Council). Initial results indicate that the vast majority of our users are satisfied with our services and data, and see FSD as a trustworthy institution. Most users thought that the data and services provided by FSD save time and money. However, users would like to have access to a wider range of up-to-date qualitative data (e.g. interview transcripts, textual data).
Quarkonium polarization in heavy ion collisions as a possible signature of the quark--gluon plasma

description: The polarization of quarkonium states produced in hadron collisions exhibits strong non-perturbative effects - for example, at small transverse momentum $p_t$ charmonia appear unpolarized, in sharp contradiction to the predictions of perturbation theory. The quark--gluon plasma is expected to screen away the non-perturbative physics; therefore those quarkonia which escape from the plasma should possess polarization as predicted by perturbative QCD. We estimate the expected $J/ψ$ polarization at small $p_t$, and find that it translates into the asymmetry of the $e^+e^- (μ^+μ^-)$ angular distribution $W(θ) \sim 1 + αcos^2θ$, with $α\simeq 0.35 ÷0.4$.

description: It has long been known that large grounded conducting networks on the surface of Earth are affected by solar activity and geomagnetic storms. Power networks are such extensive grounded conductors and are susceptible to geomagnetically induced currents (GICs). GICs at any specific node in a power network are assumed to be linearly related to the horizontal vector components of an induced plane-wave geoelectric field by a pair of network parameters. These network parameters are not easily measured in the network, but may be estimated empirically. In this work, we present a new approach of using an ensemble of network parameters estimates. The ensembles include a huge number of parameter pair estimates calculated from simultaneously solving pairs of time instances of the governing GIC equation. Each individual estimate is not the true state of the system, but a possible state. Taking the ensemble as a whole though gives the most probable parameter estimate. The most probable parameter estimate for both network parameters, as defined by their respective ensembles, is used directly in the modelling of GICs. The ensembles themselves however allow for further analysis into the nature of GICs. An improvement is seen when comparing the out-of-sample performance of the ensemble estimates with previous GIC modelling in the South African power network during the Halloween Storm of 2003. For the first time, it is shown that errors in the GIC modelling chain are absorbed into the network parameter estimates. Using a range of estimates from the ensemble, a GIC prediction band is produced. This band corresponds to an error estimate for predicted GIC. Furthermore, it has been explicitly shown that estimated network parameters vary with GIC magnitude during an event. This behaviour is then used to refine the parameter estimation further and allow for real time dynamic network parameter estimation.

Improving discovery at the UK Data Service: A systematic UX journey

description: Repositories and archives must continually review their tools and services in order to stay most relevant to evolving user needs and changes in the environment. To that end, the UK Data Service has launched a robust User Experience Programme designed to study user needs systematically as part of service development and improvement. The organisation piloted the programme through a recent project to enhance and redesign its centralised discovery portal, a process which included a highly successful user survey and qualitative interviews. This review examined the various components of the discovery system, including the user interface, browsing and search functionalities, presentation of results, filtering, cross-referencing, and more. Overall, the process to develop requirements for enhancement involved a complex, yet interactive set of tasks and work packages involving multiple sources of information (e.g. survey, interviews, and various internal records). Such a large-scale enterprise required centralised coordination, agile project management, the creation of use cases and associated requirements, and -- vitally -- teamwork and communication amongst staff in various areas (e.g. requirements developers, software engineers, user support staff, user experience specialists). This presentation will discuss the overall process and share lessons learned for other service providers seeking to review and improve their products or services.

description: We study the multiplicity of host stars to known transiting extra-solar planets to test competing theories on the formation mechanisms of hot Jupiters. We observed 45 exoplanet host stars using VLT/SPHERE/IRDIS to search for potential companions. For each identified candidate companion we determined the probability that it is gravitationally bound to its host by performing common proper motion checks and modelling of synthetic stellar populations around the host. We detected new candidate companions around K2-38, WASP-72, WASP-80, WASP-87, WASP-88, WASP-108, WASP-118, WASP-120, WASP-122, WASP123, WASP-130, WASP-131 and WASP-137. The closest candidates were detected at separations of $0.124''\pm0.007''$ and $0.189''\pm0.003''$ around WASP-108 and WASP-131; the measured $K$ band contrasts indicate that these are stellar companions of $0.35\pm0.02\,M_{\odot}$ and $0.62^{+0.05}_{-0.04}\,M_{\odot}$, respectively. Including the re-detection and confirmation of previously known companions in 13 other systems we derived a multiplicity fraction of $55.4^{+5.9}_{-9.4}\,\%$. For the representative sub-sample of 40 hot Jupiter host stars among our targets, the derived multiplicity rate is $54.8^{+6.3}_{-9.9}\,\%$. Our data do not confirm any trend that systems with eccentric planetary companions are preferably part of multiple systems. On average, we reached a magnitude contrast of $8.5\pm0.9$ mag at an angular separation of 0.5''. This allows to exclude additional stellar companions with masses larger than $0.08$ M$_\odot$ for almost all observed systems; around the closest and youngest systems this sensitivity is achieved at physical separations as small as 10 au. The presented study shows that SPHERE is an ideal instrument to detect and characterize close companions to exoplanetary host stars.

description: We present some exact scalar potentials for the dimensionally reduced theory and examine the possibility of obtaining accelerating 4d cosmology from String/M-theory, more generally, hyperbolic and flux compactification. In the hyperbolic case, even in the zero-flux limit, the scalar potential is positive for the 4d effective theory as required to get an accelerating universe, and thereby evading the ``no-go theorem'' given for static internal space. When we turn on the gauge fields as source terms at the cosmological background with potential V\propto exp(-2cϕ), we find eternally accelerating cosmologies when the 4d space-time is flat and c\geq 1, or hyperbolic and 1
