description: We construct a general Lagrangian, quadratic in the field strengths of $n$ abelian gauge fields, which interpolates between BI actions of n abelian vectors and actions, quadratic in the vector field-strengths, describing Maxwell fields coupled to non-dynamical scalars, in which the electric-magnetic duality symmetry is manifest. Depending on the choice of the parameters in the Lagrangian, the resulting BI actions may be inequivalent, exhibiting different duality groups. In particular we find, in our general setting, for different choices of the parameters, a ${\rm U}(n)$-invariant BI action, possibly related to the one in \cite{Aschieri:2008ns}, as well as the recently found $\mathcal{N}=2$ supersymmetric BI action \cite{Ferrara:2014oka}.

description: A high-resolution city map showing the geographic distribution of 12 tick species (Acari: Argasidae, Ixodidae) that have been recorded from the metropolitan area of Berlin, Germany is presented. A total of 237 tick locations was mapped. These include ten ixodid tick species: Dermacentor reticulatus, Haemaphysalis concinna, Hyalomma rufipes, Ixodes ricinus, Ixodes canisuga, Ixodes hexagonus, Ixodes arboricola, Ixodes frontalis, Ixodes trianguliceps and Rhipicephalus sanguineus sensu lato. The two tick species Hy. rufipes and R. sanguineus s.l. are not endemic to Berlin. Hyalomma rufipes ticks are introduced in Europe with migratory birds from Africa every spring. Rhipicephalus sanguineus s.l. are introduced to Central Europe with dogs that had travelled to or were imported from countries where this tick is endemic. In Germany, they are able to develop and reproduce inside heated buildings. Occurrences of two soft tick species, the pigeon tick Argas reflexus and the short-legged bat tick Carios vespertilionis were also mapped. Other tick species that are likely to be endemic to Berlin and its environs, but for which documented findings or geographical coordinates are lacking, are mentioned. These include the long-legged bat tick I. vespertilionis and the marten tick I. rugicollis documented in Brandenburg, the federal state surrounding Berlin. It can be assumed that if appropriate field studies are carried out, these tick species will also be found in the metropolitan area of Berlin. The high-resolution mapping of all tick species found in a city (like Berlin) forms the basis for further investigations into the impact of climate change and changing land use on ticks and tick-borne diseases, precisely in those habitats where most people will live in the future.

FAIR for Social Sciences

description: The FAIR Expertise Hub for the Social Sciences, funded by PDI-SSH, is being established to support data communities in the social sciences with improving their compliance with the FAIR data principles (Findable, Accessible, Interoperable, and Reusable). Since their first formal publication (Wilkinson et al., 2016), FAIR data principles have been widely adopted, globally and across different disciplines, becoming the gold standard for good data management practices. Although FAIR is flexible enough to allow each stakeholder/discipline to adapt the implementation strategy to their needs, there is still a significant amount of resources that are not FAIR, limiting interoperability and reusability within and across disciplines. This calls for a guideline with validated decisions and plans to achieve FAIRness, which is what our FAIR Expertise Hub is about.
 In the presentation, we review the current status of FAIR in the Dutch social sciences by drawing on the literature and on the insights gathered in conversations with the communities. We then outline the strategy of how the FAIR Expertise Hub plans to tackle the problems and build the gaps. In particular, we will discuss the FAIR Implementation Profile (FIP), a tool to document and support the convergence in FAIR implementation within and across disciplines. We argue that improving implementation strategies to strengthen the provision of FAIR data contributes to realising an open social science research infrastructure as the one envisioned by ODISSEI.

description: Bacterial populations grown in a lab environment are typically seen as homogeneous in terms of growth rate, size, and content. However, recent findings have shown that even during exponential growth phase, these cells can be heterogeneous. This has important consequences for how bacteria respond to stressors such as antibiotics. For example, the concept of antimicrobial persistence is linked to a small subpopulation of cells that enter a dormant state where antibiotics are no longer effective. While methods exist for identifying non-growing cells in bacterial cultures, less attention has been paid to how these cells may affect growth on solid surfaces. To address this, a low-cost, open-source platform has been developed to analyze bacterial colony growth on multiple agar plates simultaneously. The system includes a temperature-controlled chamber, high-resolution scanner, and software for extracting and plotting colony lag time and growth kinetics. The system was tested using a wild-type strain of E. coli and has the potential to provide new insights into understanding the impact of microbial heterogeneity on antibiotic resistance and persistence.

description: Communications in non-Gaussian noise channel and communication network with memory are two important but difficult frontiers of information theory. In this thesis, I studied these two areas. In the first part of this thesis, the Gaussian mixture distribution is adopted to model the non-Gaussian noise behaviour, typically found in powerline communications, man-made electromagnetic interferences, and underwater communications. Here, the capacity of a Gaussian mixture noise channel and its capacity-achieving input distribution are investigated. In the second part, I studied the capacity of a Markovian constrained relay channel and the maxentropic state transition probabilities for relay transmitter are derived. The derived results have been verified via a number of simulations.

description: Open clusters are ideal tools for tracing the abundances of different elements because their stars are expected to have the same age, distance, and metallicity. Therefore, they serve as very powerful tracers for investigating the cosmic origins of elements. This paper expands on a recent study by us, where the element Fluorine was studied in seven previously open clusters, adding six open clusters as well as eight field stars. The primary objective is to determine the abundance of fluorine (F) to gain insight into its production and evolution. The magnesium (Mg) abundances were derived to categorize the field stars into high and low alpha disk populations. Additionally, cerium (Ce) abundances are determined to better understand the interplay between F and s-process elements. The spectra were obtained from the high-resolution near-infra-red GIANO-B instrument at the Telescopio Nazionale Galileo (TNG). For the derivation of the stellar parameters and abundances, the Python version of Spectroscopy Made Easy (PySME) was used. OH, CN, and CO molecular lines and band heads along with Fe I lines were used to determine the stellar parameters in the H-band region. Two HF lines in the K-band (λλ 2.28, 2.33 μm), three K-band Mg I lines (λλ 2.10, 2.11, 2.15 μm), and two Ce II lines in the H-band (λλ 1.66, and 1.71 μm) were used to derive the abundances of F, Mg, and Ce, respectively. F, Mg, and Ce abundances were derived for 14 stars from 6 OCs, as well as 8 field stars. The F and Ce abundances were investigated as a function of metallicity, age, and Galactocentric distances. Our results indicate that asymptotic giant branch stars and massive stars, including a subset of fast rotators (whose rotation speed likely increases as metallicity decreases), are necessary to explain the cosmic origin of F.

description: In recent years, deep learning has largely embedded itself within computer vision as an extremely useful tool for accomplishing a range of vision-based tasks such as image classification, object detection and semantic segmentation. With this surge in popularity in deep learning, more traditional computer vision methods such as decision forests have somewhat fallen out of favour in the community despite their benefits. This thesis hopes to bridge this gap; it focuses on advancing the ensemble methods of decision forests and ferns and incorporating them within deep learning frameworks for computer vision applications.

description: Environments involving health services have been the focus of special attention to minimize the spread of microorganisms. UVC light systems are known to have a very powerful germicidal effect capable of inactivating a broad spectrum of microorganisms, such as viruses, bacteria, protozoa, fungi, yeasts and algae, through the formation of pyrimidine dimers. Pyrimidine dimerisation disrupts DNA replication and transcription, which leads to agent death. In this context, this study will systematically review the literature to explore the germicidal effect of UVC light on fungal and bacterial microorganisms present in medical and dental environments. Methods and approaches recognized and advocated in the literature will be adopted in the execution of this study. Systematic searches using descriptors and Boolean operators will be performed in different databases. Records that present the following characteristics will be included: (1) quantitative studies that evaluated the effectiveness of ultraviolet light emission in the disinfection of medical/dental environments; (2) quantitative studies that evaluated the effectiveness of ultraviolet light emission in the disinfection of clinical instruments; (3) quantitative studies that evaluated the effectiveness of ultraviolet light emission in the disinfection of microorganisms on laboratory plates; (4) studies that included a control group - environment/instruments/plates not exposed to ultraviolet light; (5) studies that used ultraviolet light with a wavelength ≥ 100 nanometers. Two independent researchers will perform the selection of studies, risk analysis and the assessment of the certainty of the evidence. The results of this study will be disseminated by presenting the evidence at international academic conferences and by publishing a scientific paper.
Charge carrier mobility in hybrid halide perovskites

description: The charge transport properties of hybrid halide perovskites are investigated with a combination of density functional theory including van der Waals interaction and the Boltzmann theory for diffusive transport in the relaxation time approximation. We find the mobility of electrons to be in the range 5-10 cm$^2$V$^{-1}$s$^{-1}$ and that for holes within 1-5 cm$^2$V$^{-1}$s$^{-1}$, where the variations depend on the crystal structure investigated and the level of doping. Such results, in good agreement with recent experiments, set the relaxation time to about 1 ps, which is the time-scale for the molecular rotation at room temperature. For the room temperature tetragonal phase we explore two possible orientations of the organic cations and find that the mobility has a significant asymmetry depending on the direction of the current with respect to the molecular axis. This is due mostly to the way the PbI$_3$ octahedral symmetry is broken. Interestingly we find that substituting I with Cl has minor effects on the mobilities. Our analysis suggests that the carrier mobility is probably not a key factor in determining the high solar-harvesting efficiency of this class of materials.

description: Introduction: The COVID-19 pandemic has exposed weaknesses in health systems of many countries, including those in sub-Saharan Africa. Despite comparatively low rates of COVID-19 admissions and deaths in sub-Saharan Africa, the pandemic still had a significant impact by disrupting health service utilisation (HSU). The aim of this scoping review is to synthesise the available evidence on HSU in sub-Saharan Africa during the COVID-19 pandemic, especially focusing on (1) changes in HSU compared with the prepandemic period, (2) changes in HSU among particular patient groups studied and (3) identifying factors determining changes in HSU as a result of the COVID-19 pandemic. Method and analysis: The scoping review will be guided by the methodological framework for conducting scoping reviews developed by Arskey and O’Malley. We will identify relevant studies on HSU in sub-Saharan Africa during the COVID-19 pandemic using PubMed (MEDLINE), Embase, Scopus and Web of Science databases from 1 December, 2019 to 31 March 2023. We will search grey literature, government and organisational websites for reports and conference proceedings. Included studies will be restricted to those reported in English or French. Two reviewers will independently screen articles at the title and abstract stage for inclusion into full text screening. We will provide a general descriptive overview, tabular summaries and content analysis for the extracted data. Ethics and dissemination: Ethical approval is not required for the conduct of the scoping review. We will disseminate our findings via open access peer-reviewed journals and scientific presentations. Our scoping review findings will help to determine the feasibility of a subsequent systematic review (and meta-analysis) on HSU during the COVID-19 pandemic.

description: We validate a Rp = 2.32 ± 0.24R⊗ planet on a close-in orbit (P = 2.260455 ± 0.000041 days) around K2-28 (EPIC 206318379), a metal-rich M4-type dwarf in the Campaign 3 field of the K2 mission. Our follow-up observations included multi-band transit observations from the optical to the near-infrared, low-resolution spectroscopy, and high-resolution adaptive optics (AO) imaging. We perform a global fit to all of the observed transits using a Gaussian process-based method and show that the transit depths in all of the passbands adopted for the ground-based transit follow-ups (r2″, zs,2, J, H, Ks) are within ∼2α of the K2 value. Based on a model of the background stellar population and the absence of nearby sources in our AO imaging, we estimate the probability that a background eclipsing binary could cause a false positive to be <2 × 10-5. We also show that K2-28 cannot have a physically associated companion of stellar type later than M4, based on the measurement of almost identical transit depths in multiple passbands. There is a low probability for an M4 dwarf companion (≈0.072-0.04+0.02 ), but even if this were the case, the size of K2-28b falls within the planetary regime. K2-28b has the same radius (within 1α) and experiences irradiation from its host star similar to the well-studied GJ 1214b. Given the relative brightness of K2-28 in the near-infrared (mKep = 14.85 mag and mH = 11.03 mag) and relatively deep transit (0.6%-0.7%), a comparison between the atmospheric properties of these two planets with future observations would be especially interesting.

description: We employ the IllustrisTNG simulation data to investigate the turbulent and thermal motions of the cosmic baryonic fluid. With continuous wavelet transform techniques, we define the pressure spectra, or density-weighted velocity power spectra, as well as the spectral ratios, for both turbulent and thermal motions. We find that the magnitude of the turbulent pressure spectrum grows slightly from $z=4$ to $2$ and increases significantly from $z=2$ to $1$ at large scales, suggesting progressive turbulence injection into the cosmic fluid, whereas from $z=1$ to $0$, the spectrum remains nearly constant, indicating that turbulence may be balanced by energy transfer and dissipation. The magnitude of the turbulent pressure spectra also increases with environmental density, with the highest density regions showing a turbulent pressure up to six times that of thermal pressure. We also explore the dynamical effects of turbulence and thermal motions, discovering that while thermal pressure provides support against structure collapse, turbulent pressure almost counteracts this support, challenging the common belief that turbulent pressure supports gas against overcooling.

description: Studying the properties of young planetary systems can shed light on how the dynamics and structure of planets evolve during their most formative years. Recent K2 observations of nearby young clusters (10-800 Myr) have facilitated the discovery of such planetary systems. Here we report the discovery of a Neptune-sized planet transiting an M4.5 dwarf (K2-25) in the Hyades cluster (650-800 Myr). The light curve shows a strong periodic signal at 1.88 days, which we attribute to spot coverage and rotation. We confirm that the planet host is a member of the Hyades by measuring the radial velocity of the system with the high-resolution near-infrared spectrograph Immersion Grating Infrared Spectrometer. This enables us to calculate a distance based on K2-25's kinematics and membership to the Hyades, which in turn provides a stellar radius and mass to ≃5%-10%, better than what is currently possible for most Kepler M dwarfs (12%-20%). We use the derived stellar density as a prior on fitting the K2 transit photometry, which provides weak constraints on eccentricity. Utilizing a combination of adaptive optics imaging and high-resolution spectra, we rule out the possibility that the signal is due to a bound or background eclipsing binary, confirming the transits' planetary origin. K2-25b has a radius ( 3.43-0.31 +0.95 R⊕) much larger than older Kepler planets with similar orbital periods (3.485 days) and host-star masses (0.29 M⊙). This suggests that close-in planets lose some of their atmospheres past the first few hundred million years. Additional transiting planets around the Hyades, Pleiades, and Praesepe clusters from K2 will help confirm whether this planet is atypical or representative of other close-in planets of similar age.

description: Diamidobenzene ligands are a prominent class of redox-active ligands owing to their electron reservoir behaviour, as well as the possibility of tuning the steric and the electronic properties of such ligands through the substituents on the N-atoms of the ligands. In this contribution, we present Rh(III) complexes with four differently substituted diamidobenzene ligands. By using a combination of crystallography, NMR spectroscopy, electrochemistry, UV-vis-NIR/EPR spectroelectrochemistry, and quantum chemical calculations we show that the substituents on the ligands have a profound influence on the bonding, donor, electrochemical and spectroscopic properties of the Rh complexes. We present, for the first time, design strategies for the isolation of mononuclear Rh(II) metallates whose redox potentials span across more than 850 mV. These Rh(II) metallates undergo typical metalloradical reactivity such as activation of O2 and C–Cl bond activations. Additionally, we also show that the substituents on the ligands dictate the one versus two electron nature of the oxidation steps of the Rh complexes. Furthermore, the oxidative reactivity of the metal complexes with a [CH3]+ source leads to the isolation of a unprecedented, homobimetallic, heterovalent complex featuring a novel π-bonded rhodio-o-diiminoquionone. Our results thus reveal several new potentials of the diamidobenzene ligand class in organometallic reactivity and small molecule activation with potential relevance for catalysis.

description: We confirm a 0.995 day periodic planetary transit-like signal, KOI 6705.01, in the Kepler light curve of the star KIC 6423922. Optical and infrared spectra show that this star is a mid M-type dwarf with an effective temperature K, metallicity [Fe/H] = -0.08 ±0.10, radius Ro, and mass = 0.28 ±0.05Mo. The star is pc away and its space motion, rotation period, and lack of Hα emission indicate it is an older member of the "thin disk" population. On the other hand, the star exhibits excess infrared emission suggesting a dust disk more typical of a very young star. If the KOI 6705.01 signal is produced by a planet, the transit depth of 60 ppm means its radius is only R⊕, or about the size of the Moon. However, the duration ( hr) and time variation of KOI 6705.01 are anomalous: the signal was undetected in the first two years of the mission and increased through the latter two years. These characteristics require implausible orbits and material properties for any planet and rule out such an explanation, although a dust cloud is possible. We excluded several false positive scenarios including background stars, scattered light from stars that are nearby on the sky, and electronic cross-talk between detector readout channels. We find the most likely explanation to be that KOI 6705.01 is a false positive created by charge transfer inefficiency in a detector column on which KIC 6423922 and a 1.99 day eclipsing binary both happened to fall.

description: Non-ionic detergents with tailor-made properties are indispensable tools for today's world applications, such as cleaning, disinfection, and drug discovery. To facilitate their challenging production, herein we introduce a new detergent class, namely scalable hybrid detergents. We report a combinatorial synthesis strategy that allows us to fuse head groups of different detergents into hybrid detergents with unbeatable ease. Importantly, combinatorial synthesis also enables the choice between (i) high-throughput preparation of detergents for small scale applications and (ii) large scale preparation of individual detergents. This combinatorial synthesis strategy enables an unprecedented fine tuning of detergent properties, such as overall polarity and shape, which are determining factors in applications, such as membrane protein research. Our data show that membrane protein purification parameters, such as protein yields and activity, can be linked to overall polarity and shape. Conveniently, both parameters can be theoretically described by means of the hydrophilic–lipophilic balance (HLB) and packing parameter concepts. Both concepts are principally applicable to all non-ionic detergent classes, which facilitates the identification of widely applicable design guidelines for the predictable optimization of non-ionic detergents. Our findings permit access to a yet unexplored chemical space of the detergentome, therefore creating new possibilities for structure–property relationship studies. Seen from a broader perspective, combinatorial synthesis will facilitate the preparation of designer detergents with tailor-made properties for future applications in today's world.

description: We present the first results from our Keck program investigating the orbital architectures of planet-hosting multiple star systems. Kepler-444 is a metal-poor triple star system that hosts five sub-Earth-sized planets orbiting the primary star (Kepler-444A), as well as a spatially unresolved pair of M dwarfs (Kepler-444BC) at a projected distance of 1.″8 (66 AU).We combine our Keck/NIRC2 adaptive optics astrometry with multi-epoch Keck/HIRES RVs of all three stars to determine a precise orbit for the BC pair around A, given their empirically constrained masses. We measure minimal astrometric motion (1.0 ± 0.6 mas yr?1, or 0.17 ± 0.10 km s?1), but our RVs reveal significant orbital velocity (1.7 ± 0.2 km s?1) and acceleration (7.8 ± 0.5 m s?1 yr?1). We determine a highly eccentric stellar orbit (e = 0.864 ± 0.023) that brings the tight M dwarf pair within 5.0-1.0 +0.9 AU of the planetary system. We validate that the system is dynamically stable in its present configuration via n-body simulations. We find that the A-BC orbit and planetary orbits are likely aligned (98%) given that they both have edge-on orbits and misalignment induces precession of the planets out of transit. We conclude that the stars were likely on their current orbits during the epoch of planet formation, truncating the protoplanetary disk at ≈2 AU. This truncated disk would have been severely depleted of solid material from which to form the total ≈1.5M? of planets. We thereby strongly constrain the efficiency of the conversion of dust into planets and suggest that the Kepler-444 system is consistent with models that explain the formation of most close-in Kepler planets in more typical, not truncated, disks.

description: In this paper we propose a new way of obtaining four dimensional gauge invariant $U(n)$ gauge field from a bulk action. The results are valid for both Randall-Sundrum scenarios and are obtained without the introduction of other fields or new degrees of freedom. The model is based only in non-minimal couplings with the gravity field. We show that two non-minimal couplings are necessary, one with the field strength and the other with a mass term. Despite the loosing of five dimensional gauge invariance by the mass term a massless gauge field is obtained over the brane. To obtain this, we need of a fine tuning of the two parameters introduced through the couplings. The fine tuning is obtained by imposing the boundary conditions and to guarantee non-abelian gauge invariance in four dimensions. With this we are left with no free parameters and the model is completely determined. The model also provides analytical solutions to the linearized equations for the zero mode and for a general warp factor.

description: Purpose: Our aim was to examine whether quality of life which was repeatedly assessed over time is related with the comprehensive assessment of quality of life (QoL) and thereby to validate a brief QoL assessment. Method: This longitudinal study used a comprehensive assessment of quality of life at baseline (QUALIDEM; 37 items) to validate an eight-item version of QUALIDEM to assess momentary quality of life which was repeatedly administered using a tablet device after baseline. In all, 150 people with dementia from 10 long-term facilities participated. Momentary quality of life and comprehensive quality of life, age, gender, activities of daily living (Barthel Index), Functional assessment staging (FAST), and Geriatric Depression (GDS) have been assessed. Results: Comprehensive and momentary quality of life showed good internal consistency with Cronbach’s alpha of .86 and .88 to .93, respectively. For multiple associations of momentary quality of life with the comprehensive quality of life, momentary quality of life was significantly related to comprehensive quality of life (B = .14, CI .08/.20) and GDS (B = − .13, CI − .19/− .06). More specifically, the comprehensive QUALIDEM subscales ‘positive affect’, ‘negative affect’, ‘restlessness’, and ‘social relationships’ showed significant positive associations with momentary quality of life (p < .001). Conclusion: We found that momentary quality of life, reliably assessed by tablet, was associated with comprehensive measures of quality of life and depressive symptoms in people with dementia. Broader use of tablet-based assessments within frequent QoL measurements may enhance time management of nursing staff and may improve the care quality and communication between staff and people with dementia.

description: For a one-parameter family of lower triangular matrices with entries involving continuous $q$-ultraspherical polynomials we give an explicit lower triangular inverse matrix, with entries involving again continuous $q$-ultraspherical functions. The matrices are $q$-analogues of results given by Cagliero and Koornwinder recently. The proofs are not $q$-analogues of the Cagliero-Koornwinder case, but are of a different nature involving $q$-Racah polynomials. Some applications of these new formulas are given. Also the limit $β\to 0$ is studied and gives rise to continuous $q$-Hermite polynomials for $0 < q < 1$ and $q > 1$.

description: We analyze recent developments in Bolivia’s politics through the lens of political cleavage theory, in particular cleavage displacement. Bolivia’s current party system is characterized by a stable and dominant MAS at one end of the spectrum, and at the other a fractious, unstable collection of parties, movements, and other vehicles that have failed to articulate a coherent set of political ideas. It emerged when the previous party system collapsed in 2003-05, shifting politics from a conventional left-right axis of competition unsuited to Bolivian society, to an ethnic/ rural vs. cosmopolitan/urban axis closely aligned with its major social cleavage. But society did not freeze in 2005. We analyze the deep roots of Bolivia’s current politics, and explore emerging or changing generational, ethnic, urban-rural, regional, class, and religious divides. Understanding how cleavages interact to determine political outcomes allows us to make sense of the deep tensions and sources of instability that both Bolivia, and the MAS internally, currently face, and to shine a light on major coming challenges.
