description: We present $UBVRI$ photometry of 8702 stars in a $0.5 ^\circ\times0.5 ^\circ$ field in the direction of NGC 7142, taken with the Half Degree Imager (HDI) at the WIYN 0.9-meter telescope, to improve knowledge of this cluster's basic parameters. Our photometry spans the ranges 10.6 - 20.4 mag in $U$, 10.6 - 22.0 mag in $B$, 10.0 - 21.8 mag in $V$, 9.2 - 20.7 mag in $R$, and 8.5 - 19.9 mag in $I$. Using color-color diagrams that employ all four color combinations that include $U$, versus $B-V$, we derive a reddening-metallicity relation for the cluster, with preferred values $E(B-V$) = 0.338 $\pm$ 0.031 mag for the left-edge fiducial of the main sequence and [Fe/H] = 0.0 $\pm$ 0.1 dex, where the Hyades cluster has been used as an unreddened reference cluster, the extinction relations of Cardelli have been employed, and the metallicity dependence of the Yonsei-Yale ($Y^2$) isochrones has been assumed. Comparison of our data to the $Y^2$ isochrones in multiple color-magnitude diagrams (CMDs) yields distance-metallicity and age-metallicity relations, with preferred values of $m-M\ =\ 12.65\ \pm\ 0.23$ mag and age = $4.0 ^{-0.7}_{+1.3}$ Gyr. Re-evaluation of the parameters of M67 using Stetson's $UBVI$ photometry yields [Fe/H] = -0.02 $\pm$ 0.05 dex, $E(B-V$) = 0.04 $\pm$ 0.01 mag, $m-M$ = 9.75 $\pm$ 0.03 mag, and age = 3.85 $\pm$ 0.17 Gyr; we thus find the metallicity and age of the two clusters to be indistinguishable. A semi-independent analysis adopting the parameters of M67 and shifting the fiducials of the two clusters in six CMDs until they match strongly corroborates the values listed above. The differences between our inferred parallaxes and the Gaia DR2 values are $87\ \pm\ 60$ $μ$as for NGC 7142 and 48 $\pm$ 15 $μ$as for M67, consistent with previous studies.

description: At a prospective e+e- Linear Collider (LC) a very precise determination of the top quark mass with an accuracy of $δm_t <= 100 MeV$ will be possible. This is to be compared with the envisaged accuracy of $δm_t = 1-2 GeV$ at the Tevatron and the LHC. We discuss the physics impact of such a precise determination of m_t, focusing on the Standard Model (SM) and its minimal supersymmetric extension (MSSM). In particular, we show the importance of a precise knowledge of m_t for electroweak precision observables, and for Higgs physics and the scalar top sector of the MSSM. Taking the mSUGRA model as a specific example, we furthermore demonstrate the importance of a precise m_t value for the prediction of sparticle masses and for constraints on the parameter space allowed by the relic density. The uncertainty in m_t also significantly affects the reconstruction of the supersymmetric high scale theory. We find that going from hadron collider to LC accuracy in m_t leads to an improvement of the investigated quantities by up to an order of magnitude.

The state of data visualization support in libraries

Year: 2018

description: Data visualization is a rapidly expanding field whose skills, techniques and insights are increasingly intertwined in disciplines across and beyond academia. Given the interdisciplinary nature of data visualization, libraries are uniquely situated to support building skills and communities of practice in this area. A growing number of academic libraries provide instruction, consultation, technology, and spaces to support data visualization as part of a broader expansion in library data services. Since few graduate programs in library science offer training in data visualization, many later career librarians are finding it necessary to develop data visualization skills on the job. Due to factors, including lack of resources, time, and training opportunities, one of the great challenges for researchers and librarians is developing the necessary skill set and expertise in data visualization to engage critically in the discipline. This presentation will provide an overview of current visualization services in a number of academic libraries and the state of the field. It will include an overview of opportunities and challenges as well as a discussion of ways that libraries can expand both their tool-based and critical support for data visualization and data visualization literacy.
Peculiar Features of the Velocity Field of OB Associations and the Spiral Structure of the Galaxy
Creators: name: Mel'nik, A. M.
Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Some of the peculiar features of the periodic velocity-field structure for OB associations can be explained by using the model of Roberts and Hausman (1984), in which the behavior of a system of dense clouds is considered in a perturbed potential. The absence of statistically significant variations in the azimuthal velocity across the Carina arm, probably, results from its sharp increase behind the shock front, which is easily blurred by distance errors. The existence of a shock wave in the spiral arms and, at the same time, the virtually free motion of OB associations in epicycles can be reconciled in the model of particle clouds with a mean free path of 0.2-2 kpc. The velocity field of OB associations exhibits two appreciable nonrandom deviations from an ideal spiral pattern: a 0.5-kpc displacement of the Cygnus- and Carina-arm fragments from one another and a weakening of the Perseus arm in quadrant III. However, the identified fragments of the Carina, Cygnus, and Perseus arms do not belong to any of the known types of spurs.

description: Magnetic field fluctuations in the solar wind are commonly observed to follow a power law spectrum. Near proton-kinetic scales, a spectral break occurs which is commonly interpreted as a transition to kinetic turbulence. However, this transition is not yet entirely understood. By studying the scaling of the break with various plasma properties, it may be possible to constrain the processes leading to the onset of kinetic turbulence. Using data from Parker Solar Probe (\textit{PSP}), we measure the proton scale break over a range of heliocentric distances, enabling a measurement of the transition from inertial to kinetic scale turbulence under various plasma conditions. We find that the break frequency $f_b$ increases as the heliocentric distance $r$ decreases in the slow solar wind following a power law $f_b\sim r^{-1.11}$. We also compare this to the characteristic plasma ion scales to relate the break to the possible physical mechanisms occurring at this scale. The ratio between $f_b$ and $f_c$, the Doppler shifted ion cyclotron resonance scale, is approximately unity for all plasma $β_p$. At high $β_p$ the ratio between $f_b$ and $f_ρ$, the Doppler shifted gyroscale, is approximately unity; while at low $β_p$ the ratio between $f_b$ and $f_d$, the Doppler shifted proton-inertial length is unity. Due to the large comparable Alfvén and solar wind speeds, we analyze these results using both the standard and modified Taylor hypothesis, demonstrating robust statistical results.

Observational signatures of the weak lensing magnification of supernovae
Creators: name: Wang, Yun
Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Due to the deflection of light by density fluctuations along the line of sight, weak lensing is an unavoidable systematic uncertainty in the use of type Ia supernovae (SNe Ia) as cosmological distance indicators. We derive the expected weak lensing signatures of SNe Ia by convolving the intrinsic distribution in SN Ia peak luminosity with magnification distributions of point sources. We analyze current SN Ia data, and find marginal evidence for weak lensing effects. The statistics is poor because of the small number of observed SNe Ia. Future observational data will allow unambiguous detection of the weak lensing effect of SNe Ia. The observational signatures of weak lensing of SNe Ia that we have derived provide useful templates with which future data can be compared.

From paper map to geospatial vector layer: Demystifying the process
Creators: name: Peller, Peter
Publisher: name: Zenodo
Year: 2018

description: With paper map use in decline, one of the strategies that libraries can adopt to make the information contained within them more accessible and usable is to extract features of interest from their scanned raster maps and convert those to geospatial vector data. This process adds valuable, unique data to library geospatial collections and enables those previously map-bound features to be used separately in geographic information systems (GIS) software for custom mapping and analysis. Advances in partially automating most of the process have made this a much more viable option for libraries. Although there is no one-size-fits-all automated solution for all maps and map features, this paper provides a complete description of the entire process incorporating examples of the various techniques and software used in selected studies that would be applicable in the library environment.

description: Clusters of galaxies can be identified from peaks in weak lensing aperture mass maps constructed from weak lensing shear catalogs. Such purely gravitational cluster selection considerably differs from traditional cluster selections based on baryonic properties of clusters. In this review, we present the basics and applications of weak lensing shear-selected cluster samples. Detailed studies of baryonic properties of shear-selected clusters shed new light on cluster astrophysics. The purely gravitational selection suggests that the selection function can be quantified more easily and robustly, which is crucial for deriving accurate cosmological constraints from the abundance of shear-selected clusters. The recent advance of shear-selected cluster studies is driven by the Subaru Hyper Suprime-Cam survey, in which more than 300 shear-selected clusters with the signal-to-noise ration greater than 5 are identified. It is argued that various systematic effects in the cosmological analysis can be mitigated by carefully choosing the set-up of the analysis, including the choice of the kernel functions and the source galaxy sample.

New Soft Theorems for Goldstone Boson Amplitudes

Publisher: name: arXiv
Year: 2019

description: In this letter we discuss new soft theorems for the Goldstone boson amplitudes with non-vanishing soft limits. The standard argument is that the non-linearly realized shift symmetry leads to the vanishing of scattering amplitudes in the soft limit, known as the Alder zero. This statement involves certain assumptions of the absence of cubic vertices and the absence of linear terms in the transformations of fields. For theories which fail to satisfy these conditions, we derive a new soft theorem which involves certain linear combinations of lower point amplitudes, generalizing the Adler zero statement. We provide an explicit example of $SU(N)/SU(N-1)$ sigma model which was also recently studied in the context of $U(1)$ fibrated models. The soft theorem can be then used as an input into the modified soft recursion relations for the reconstruction of all tree-level amplitudes.

Spectator interactions in B -> V gamma decays and QCD factorisation

description: We study the radiative decays B -> V gamma (where V=rho, K^*) in the framework of QCD factorisation, and in particular the hard-spectator contributions to the decay amplitudes. For the phenomenologically significant chromomagnetic operator, we show by an explicit next-to-leading-order computation that the spectator interactions factorise in the heavy-quark limit, i.e. that they can be written as the convolution of a hard-scattering kernel, computable in perturbation theory, and of the light-cone distribution amplitudes for the B and V mesons which contain the soft physics. The presence of an intermediate scale of order sqrt{Lambda_QCD M_B} leads to the presence of Sudakov logarithms. We indicate how the proof of factorisation can be extended to other (four-quark) operators.

Lyman Continuum Escape Fraction in Ly$α$ Emitters at $z\simeq3.1$

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: We measure the LyC escape fraction in 54 faint Lyman Alpha Emitters (LAEs) at $z\simeq3.1$ in the GOODS-South field. With the average magnitude of $R=26.7$ AB ($M_{UV}=-18.8$, $L\simeq0.1L^*$), these galaxies represent a population of compact young dwarf galaxies. Their properties are likely to resemble those in the galaxies responsible for reionising the Universe at $z>6$. We do not detect LyC emission in any individual LAEs in the deep {\em HST} F336W images, which covers the rest-frame 820Å. We do not detect the LyC emission of these LAEs in the stacked F336W images, either. The $3σ$ upper limit of LyC escape fractions is $f_{\rm esc}<14-32\%$. However, the high Ly$α$ rest-frame equivalent width, low stellar mass and UV luminosity of these LAEs suggest that they should have $f_{\rm esc}>50\%$. The low LyC escape fraction from this work and other stacking analysis suggest that the LyC leaking galaxies with $f_{\rm esc} > 50\%$ at $z=2-3$ do not follow the relation between the $f_{\rm esc}$ and UV luminosity and Ly$α$ equivalent width (EW) derived from typical galaxies at similar redshift. Therefore, the UV luminosity and Ly$α$ equivalent width (EW) are not the best indicators for the LyC escape fraction.

Can there be a heavy sbottom hidden in three-jet data at LEP?
Creators: name: Malhotra, Rahul
Publisher: name: arXiv
Year: 2003
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: A low-energy supersymmetry scenario with a light gluino of mass 12 - 16 GeV and light sbottom (b1) of mass 2 - 6 GeV has been used to explain the apparent overproduction of b quarks at the Tevatron. In this scenario the other mass eigenstate of the sbottom, i.e. b2, is favored to be lighter than 180 GeV due to constraints from electroweak precision data. We survey its decay modes in this scenario and show that decay into a b quark and gluino should be dominant. Associated sbottom production at LEP via e+ e- -> Z* -> b1 b2* + b1* b2 is studied and we show that it is naturally a three-jet process with a small cross-section, increasingly obscured by a large Standard Model background for heavier b2. However we find that direct observation of a b2 at the 5-sigma level is possible if it is lighter than 110 - 129 GeV, depending on the sbottom mixing angle |cos(theta_b)| = 0.30 - 0.45. We also show that b2-pair production can be mistaken for production of neutral MSSM Higgs bosons in the channel e+ e- -> h^0 A^0 -> b b-bar b b-bar. Using searches for the latter we place a lower mass limit of 90 GeV on b2.

Hero of the Under-Bog : The case for allegory as landscape care
Creators: name: Wilson, Meredith
Publisher: name: The University of British Columbia
Year: 2023

description: The Bog has been a repeated source of mystery, wonder, horror, and beauty in folklore and popular culture. Storytellers use the Bog to evoke an eerie atmosphere or as a testing challenge for its heroes. In the modern world, however, the prevailing narrative villainized the Bog. Countless wetlands throughout the western world were dredged, dammed, and diked to make way for urban development. Landscape architecture can use fictional narrative as a tool to restore our relationship to place - otherwise known as place meaning. The selected site for this project is a remnant Bog in East Vancouver, with soft peat soils that wreak havoc on infrastructure and aging homes. Opportunity exists to restore the whimsy of the Bog by using the proposed framework, “Allegory as Care”. Hero of the Under-Bog intends to connect the neighbourhood to the landscape and all that it offers through the lens of a classic folk hero. The physical book could be placed in the little free library and circulated throughout the community.
Transparency in practice: Testing annotation for transparent inquiry (ATI)
Creators: name: Elman, Colin

Publisher: name: Zenodo
Year: 2018

description: This paper presents initial results of a study assessing a new approach to achieving transparency in qualitative research in the health and social sciences: Annotation for Transparent Inquiry (ATI), which is being developed at the Qualitative Data Repository (QDR). Data sharing and transparency have demonstrated benefits in quantitative social science. Scholars have used replication data to generate new findings, to find errors in existing studies, to teach applied quantitative methods, and in some cases to detect outright fraud. As norms for transparency and data sharing are spreading to qualitative research, we need to properly understand the costs and benefits that transparency provides in such inquiry. To assess ATI, we contracted the authors of 15 recently published qualitative studies in health and social science to annotate their work following ATI guidelines. We matched them with 15 reviewers. Authors were asked to catalog their observations and effort as they annotated, and to reflect on the experience once they completed their project. Reviewers evaluated the article both with and without annotations, considering benefits and undesirable effects of annotation. The paper includes an analysis of both groups' answers, and draws on discussions from a related two-day workshop in February 2018.
title: Neither relational nor discrete: the ISDA master agreement as a bimodal contract
Creators: name: Armitage, Matthew
Publisher: name: University of Reading
Year: 2024

description: Relational contract theory could, under English law, be considered simply that: an 
academic theory, too impractical to implement and too imprecise to fulfil ambitions of 
legal certainty. However, even in the face of subsequent judicial reluctance,1 the cases 
of Yam Seng2 and Bates v Post Office3 have paved the way for this theoretical 
construct to permeate practical considerations of commercial contract law. The theory 
posits, inter alia, that there is a spectrum, at one end are discrete contracts, which are 
simple exchanges, and at the other end are relational contracts, which depend not 
only on the contract between the parties but on the relationship underpinning it.4
The original contribution offered by this thesis is to offer a new category of contract -
the bimodal contract - centred around unpacking tangential comments made in the 
relational contract literature that many contracts will contain both discrete and relational terms. By using the ISDA Master Agreement - an international, standard form agreement - as a case study, we can begin to understand some of the elements 
which could be utilised as part of a discrete/relational contract spectrum analysis -
namely, the composition and intentions of the drafting party, the market in which the 
agreement is used, and the technological developments being built to complement, 
facilitate, and, in some cases, supplant traditional contract drafting and negotiation -
and how these elements can form part of a macro-level analysis, accompanying any 
particular interpretative considerations around party or transactional context. From 
this analysis, the aim is to understand where the ISDA Master Agreement fits on, and 
to develop a broad framework for how to assess analogous standard-form agreements
within the concept of, the discrete/relational contract spectrum.

description: We present a systematic procedure to compute complete, analytic form factors of gauge-invariant operators at loop level in pure Yang-Mills. We consider applications to operators of the form $\mathrm{Tr}\, F^n$ where $F$ is the gluon field strength. Our approach is based on an extension to form factors of the dimensional reconstruction technique, in conjunction with the six-dimensional spinor-helicity formalism and generalised unitarity. For form factors this technique requires the introduction of additional scalar operators, for which we provide a systematic prescription. We also discuss a generalisation of dimensional reconstruction to any number of loops, both for amplitudes and form factors. Several novel results for one-loop minimal and non-minimal form factors of $\mathrm{Tr}\, F^n$ with $n>2$ are presented. Finally, we describe the \texttt{Mathematica} package \texttt{SpinorHelicity6D}, which is tailored to handle six-dimensional quantities written in the spinor-helicity formalism.

description: Forecasting the dynamics of chaotic systems from the analysis of their output signals is a challenging problem with applications in most fields of modern science. In this work, we use a laser model to compare the performance of several machine learning algorithms for forecasting the amplitude of upcoming emitted chaotic pulses. We simulate the dynamics of an optically injected semiconductor laser that presents a rich variety of dynamical regimes when changing the parameters. We focus on a particular dynamical regime that can show ultra-high intensity pulses, reminiscent of rogue waves. We compare the goodness of the forecast for several popular methods in machine learning, namely deep learning, support vector machine, nearest neighbors and reservoir computing. Finally, we analyze how their performance for predicting the height of the next optical pulse depends on the amount of noise and the length of the time-series used for training.

description: We present reddening maps of the Large Magellanic Cloud (LMC) and Small Magellanic Cloud (SMC), based on color measurements of the red clump. Reddening values of our maps were obtained by calculating the difference of the observed and intrinsic color of the red clump in both galaxies. To obtain the intrinsic color of the red clump, we used reddenings obtained from late-type eclipsing binary systems, measurements for blue supergiants and reddenings derived from Strömgren photometry of B-type stars. We obtained intrinsic color of the red clump $(V-I)_0$ = 0.838 $\pm$ 0.034 mag in the LMC, and $(V-I)_{0}$ = 0.814 $\pm$ 0.034 mag in the SMC. We prepared our map with 3 arcmin resolution, covering the central part of the LMC and SMC. The mean value of the reddening is E$(B-V)_{\mathrm{LMC}}$=0.127 mag and E$(B-V)_{\mathrm{SMC}}$=0.084 mag for the LMC and SMC, respectively. The systematic uncertainty of the average reddening value assigned to each field of our maps is 0.013 mag for both Magellanic Clouds. Our reddening values are on average higher by 0.061 mag for the LMC and 0.054 mag for the SMC, compared with the maps of Haschke et al. (2011). We also compared our values with different types of reddening tracers. Cepheids, RR Lyrae stars, early-type eclipsing binaries and other reddening estimations based on the red clump color on average show reddenings consistent with our map to within a few hundredths of magnitude.

description: Social science researchers are responding to concerns about failures to replicate research, p-hacking, and other dubious practices by developing new procedures to increase transparency and accountability. Among these is pre-registration of research projects before beginning collection or analysis of research data, which forces researchers to better distinguish between findings resulting from a priori hypotheses versus exploration. In pre-registering our own research, we found it difficult to fully describe analysis procedures before viewing the messy and complex data that often result from social science collection. Decisions about how to deal with unexpected properties of the data, such as outliers and skew, are difficult to predict beforehand. We have found ourselves conflicted on how to handle this, as we failed to address these possibilities in our pre-registration. We expect other researchers confront these and other dilemmas with their pre-registrations; how do they handle them? To answer this, we examined analysis plans from pre-registrations filed on the Open Science Framework (OSF) website. These plans varied widely in detail and description of conditional analyses, demonstrating others likely faced similar dilemmas. This presentation will summarize patterns across existing OSF pre-registrations and open discussion on strategies for finding a balance between sufficient detail and analytical flexibility.

 Basionym:— Chandonanthus difficilis Steph., J. & Proc. Roy. Soc. New South Wales 48: 101, 1914 (Stephani & Watts 1914).
 Type:— VANUATU. Aneityum, Gunn, hb. Watts 29 (holotype G-60753!).
 Note:— Chandonanthus difficilis is closely related to Plicanthus hirtellus. However, the type specimen is vigorous and more dense with more imbricate leaves with large marginal teeth. Underleaves are much smaller than normal sized Plicanthus hirtellus and very ciliate. For that reason we retain the species until the Plicanthus / Chandonanthus / Tetralophozia complex have been studied further, preferably also molecularly.

The role of data supplements in reproducibility: Curation challenges
Creators: name: Butler, Courtney

Publisher: name: Zenodo
Year: 2018

description: While raw data and its collection methods are increasingly made available and well described, output materials created from third party data are more often provided to comply with journal policies on replication with little thought given to reuse. Thus, they are often treated as secondary supplements to the primary research object (the published paper) and are lower priorities for curation. However, research may be verified and built upon through a number of methods that go beyond basic replication, such as reanalysis and extension. In order for curation activities to properly support these progressions, this means broadening the discussion of what constitutes a primary research object so that all necessary components of a research project, including supplements, are discoverable and usable. This presentation will discuss the curation challenges in treating all types of data and code as primary research objects and strategies to overcome these obstacles.

description: We extend the recently introduced divergence-conforming immersed boundary (DCIB) method [1] to fluid-structure interaction (FSI) problems involving closed co-dimension one solids. We focus on capsules and vesicles, whose discretization is particularly challenging due to the higher-order derivatives that appear in their formulations. In two-dimensional settings, we employ cubic B-splines with periodic knot vectors to obtain discretizations of closed curves with C^2 inter-element continuity. In three-dimensional settings, we use analysis-suitable bi-cubic T-splines to obtain discretizations of closed surfaces with at least C^1 inter-element continuity. Large spurious changes of the fluid volume inside closed co-dimension one solids is a well-known issue for IB methods. The DCIB method results in volume changes orders of magnitude lower than conventional IB methods. This is a byproduct of discretizing the velocity-pressure pair with divergence-conforming B-splines, which lead to negligible incompressibility errors at the Eulerian level. The higher inter-element continuity of divergence-conforming B-splines is also crucial to avoid the quadrature/interpolation errors of IB methods becoming the dominant discretization error. Benchmark and application problems of vesicle and capsule dynamics are solved, including mesh-independence studies and comparisons with other numerical methods.

Making Bright Giants Invisible At The Galactic Centre

description: Current observations of the Galactic Center (GC) seem to display a core-like distribution of bright stars from $\sim 5"$ inwards. On the other hand, we observe young, massive stars at the GC, with roughly 20-50\% of them in a disc, mostly in the region where the bright giants appear to be lacking. In a previous publication we put the idea forward that the missing stars are deeply connected to the presence of this disc. The progenitor of the stellar disc is very likely to have been a gaseous disc that at some point fragmented and triggered star formation. This caused the appearance of overdensity regions in the disc that had high enough densities to ensure stripping large giants of their atmospheres and thus rendering them very faint. In this paper we use a stellar evolution code to derive the properties that a red giant would display in a colour-magnitude diagram, as well as a non-linearity factor required for a correct estimate of the mass loss. We find that in a very short timescale, the red giants (RGs) leave their standard evolutionary track. The non-linearity factor has values that not only depend on the properties of the clumps, but also on the physical conditions the giant stars, as we predicted analytically. According to our results, envelope stripping works, moving stars on a short timescale from the giant branch to the white dwarf stage, thus rendering them invisible to observations.

The unusual supernova remnant surrounding the ultraluminous X-ray source IC 342 X-1

description: We report the results of an observation of a large diameter (110 pc) supernova remnant (SNR) found to encircle the position of the ultraluminous X-ray source (ULX) IC 342 X-1. The inferred initial energy input to the SNR is at least 2 -- 3 times greater than the canonical energy for an ``ordinary'' supernova remnant. Two regions on the inside of the shell are bright in [O III] lambda5007 emission, possibly as the result of X-ray photoionization by the ULX. If this is the case, then the morphology of this nebulosity implies that the X-ray emission from the ULX is anisotropic. The presence of the ULX, most probably a black hole X-ray binary, within an unusually energetic supernova remnant suggests that we may be observing the aftermath of a gamma-ray burst, though other origins for the energetic nebula are discussed.

description: The XENONnT experiment aims to directly detect dark matter (DM) particles using a dual-phase xenon time projection chamber (TPC). A particle interaction is detected via a prompt light signal and a delayed charge signal. In this work, three aspects essential for the direct search for DM are explored. To contribute to the general characterization of the XENONnT detector, the existence of a volume in the TPC is verified that exhibits a partial or complete loss of the charge signal. This region accounts for about 3 % of the active volume and is largest in the lower outer part of the TPC. The second part of this work focuses on a systematic study to find suitable goodnessof-fit (GOF) tests for the analysis of typical recoil bands of XENONnT. A strong dependence of the GOF test result on the binning is investigated and a solution using an irregular binning scheme is presented. Compared to several other GOF tests, the tests using this binning are best suited for identifying fits with incomplete models. In the third part, a contribution is made to the development of a system for the fully automated krypton assay of future DM detectors by providing a proof of concept for an automated gas chromatography system. The system parameter stability of the prototype is demonstrated under realistic conditions with relative errors below 0.15 %.

description: Maximising dividends is one classical stability criterion in actuarial risk theory. Motivated by the fact that dividends are paid periodically in real life, $\textit{periodic}$ dividend strategies were recently introduced (Albrecher, Gerber and Shiu, 2011). In this paper, we incorporate fixed transaction costs into the model and study the optimal periodic dividend strategy with fixed transaction costs for spectrally negative Lévy processes. The value function of a periodic $(b_u,b_l)$ strategy is calculated by means of exiting identities and Itô's excusion when the surplus process is of unbounded variation. We show that a sufficient condition for optimality is that the Lévy measure admits a density which is completely monotonic. Under such assumptions, a periodic $(b_u,b_l)$ strategy is confirmed to be optimal. Results are illustrated.
