description: Die Vorstellung von der Weitergabe von Ideen und Wissen durch Texte ist uns vertraut. Das Bild führt aber auch ein ›Eigenleben‹ gegenüber dem begleitenden und erläuternden Text. Das ist bisher kaum beachtet worden. Der Beitrag greift dieses Problem am Beispiel historischer Kinder- und Jugendliteratur auf und fokussiert hier im Besonderen die Gattung der Wissen vermittelnden Bücher. Auf diese Weise sollen die Entstehungszusammenhänge ihrer Illustrationen gezeigt und ihre Bezüge rekonstruiert werden. So lässt sich die didaktische Auswahl der Bildinhalte besser verstehen, die im 18. und 19. Jahrhundert als relevant für die Bildung des Kindes erachtet wurde. Der Lösungsweg ist interdisziplinär und verbindet die bibliothekarische Perspektive bei der Digitalisierung und Bereitstellung der Bildquellen, zwei heterogene informationswissenschaftliche Verfahren zur Ähnlichkeitssuche und die fachwissenschaftliche Expertise zur Kinderbuchforschung. Eignung und Reichweite der Verfahren werden verglichen und kritisch reflektiert.
description: The perception of the transmission of ideas and knowledge through texts is well-known to us. But the image also has a »life of its own« in relation to the text that accompanies and explains it. This has hardly been taken into notice so far. The paper takes up this problem using the example of historical children's and youth literature and focuses here in particular on the genre of books teaching knowledge. In this way, the contexts of origin of the book illustrations will be shown and their references reconstructed. In consequence, the didactic selection of the image content, which was considered relevant for the education of the child in the 18th and 19th century, can be better understood. The way to a solution is interdisciplinary and combines the library perspective in digitizing and providing the image sources, two heterogeneous information science methods for similarity search and the subject-specific expertise in children's book research. We will compare and critically reflect on the suitability and scope of the methods.

description: Energy demand globally has been increasing over the last few decades and, in order to achieve climate neutrality in the EU by 2050, the demand for energy needs to be reduced without affecting the comfort of the citizens. Therefore, the role of energy efficiency measures and renewable energy use has become pivotal in energy science. However, designing policies related to the promotion of energy efficiency or usage of renewable energy depends immensely on the evidence/predictions for a set of scenarios up to a certain timeline that can be provided by the energy demand models. In other words, the findings of energy models can help in identifying the focus area of the policies. Thus, different sector-specific energy demand models can showcase the impact of different policy measures on final energy demand. Since the policy-design in a way depends on the findings of energy demand models, we need to understand whether the demand models can incorporate all of the key parameters and needs of model users (such as policymakers, academicians, NGOs, etc.) into consideration while calculating final energy demand. Thus, to understand the different user needs, this study has used a three-tier methodological approach consisting of a focused literature review (conducted under SENTINEL Deliverables D3.1 and D1.2), an online survey and online interviews with different user groups, and lastly, stakeholder workshops. This three-tier methodological approach unfolds mainly two categories of user-needs: generic/transversal user-needs, and sector-specific user-needs. With the help of four different demand models used in SENTINEL, most of the user-needs are taken into account and this report discusses in detail how individual user-needs are getting addressed through demand models. Some of the user-needs (for example ‘energy demand transition between 2030- 2050’ and ‘role of renewable electricity to meet demand’) can be addressed with the SENTINEL demand models without requiring any upgrades of the models. However, for some of the needs (such as ‘onsite energy production (prosumer profile)’ for the building sector, or ‘fleet distribution’ in the mobility sector) the respective demand models for each sector need some upgrades to address the needs. The objective of this report is to discuss each of the user-needs identified through our three-tier methodology and, further, to document how these needs can be incorporated when calculating final energy demand until 2050. Lastly, this report discusses the next steps after incorporating the energy-needs and also defines a conceptual framework on how different demand models can come together to calculate the sector specific total energy demand which can be then used by the SENTINEL system design and supply modelling module in WP4.
Beyond the Inquisition: Ambrogio Catarino Politi and the Origins of the Counter-Reformation
Creators: name: Caravale, Giorgio
Publisher: name: University of Notre Dame
Year: 2023

description: In _Beyond the Inquisition_, originally published in an Italian edition in 2007, Giorgio Caravale offers a fresh perspective on sixteenth-century Italian religious history and the religious crisis that swept across Europe during that period. Through an intellectual biography of Ambrogio Catarino Politi (1484-1553), Caravale rethinks the problems resulting from the diffusion of Protestant doctrines in Renaissance Italy and the Catholic opposition to their advance. At the same time, Caravale calls for a new conception of the Counter-Reformation, demonstrating that during the first half of the sixteenth century there were many alternatives to the inquisitorial model that ultimately prevailed. \u000a\u000aLancellotto Politi, the jurist from Siena who entered the Dominican order in 1517 under the name of Ambrogio Catarino, started his career as an anti-Lutheran controversialist, shared friendships with the Italian Spirituals, and was frequently in conflict with his own order. The main stages of his career are all illustrated with a rich array of previously published and unpublished documentation. Caravale's thorough analysis of Politi's works, actions, and relationships significantly alters the traditional image of an intransigent heretic hunter and an author of fierce anti-Lutheran tirades. In the same way, the reconstruction of his role as a papal theologian and as a bishop in the first phase of the Council and the reinterpretation of his battle against the Spanish theologian Domingo de Soto and scholasticism reestablish the image of a Counter-Reformation that was different from the one that triumphed in Trent, the image of an alternative that was viable but never came close to being implemented.

description: Stereotypical behaviour in higher education has been linked with inequality with relevant negative output. This project’s aim is to replicate the design of a previous study by expanding further into exploring the gender stereotypes’ relationships for two traditionally gendered polarised areas of study: Engineering and Nursing/ Midwifery and assessing participants’ earlier experiences in their secondary education. Survey participants were Engineering and Nursing/Midwifery students (N = 161) of a university in Ireland. Results came positive for stereotypical biases in favour to men in Science, Technology, Engineering and Mathematics (STEM), and specifically for Mathematics. Stereotypes emerged stronger among the female participants. While comparing the two genders within each of the two study areas, significant differences emerge among the female Nursing/Midwifery and female Engineering participants. Female Engineering participants appear with stronger preference, attitude and importance towards STEM than their Nursing/Midwifery counterparts. Nevertheless, Mathematics is an indicator subject for success in higher education and the need to strengthen critical thinking, evidenced based practice and quality of quantitative research in female dominated areas such as Nursing/Midwifery has been recognised. In addition to identified stereotypes, differences in respondents’ views/elements of their interaction with STEM were associated with the type of secondary school they attended. Further research is recommended on traits that could contribute to the formation of gender biased stereotypes in single and mixed gender education systems with an aim to reverse them
The CO luminosity and CO-H2 conversion factor of diffuse ISM: does CO emission trace dense molecular gas?

description: Aims: We wish to separate and quantify the CO luminosity and CO-H2 conversion factor applicable to diffuse but partially-molecular ISM when H2 and CO are present but C+ is the dominant form of gas-phase carbon. Methods: We discuss galactic lines of sight observed in \HI, HCO+ and CO where CO emission is present but the intervening clouds are diffuse (locally \AV\ $\la 1$ mag) with relatively small CO column densities $\NCO \la 2\times10^{16}\pcc$. We separate the atomic and molecular fractions statistically using \EBV\ as a gauge of the total gas column density and compare NH2 to the observed CO brightness. Results: Although there are H2-bearing regions where CO emission is too faint to be detected, the mean ratio of integrated CO brightness to NH2 for diffuse ISM does not differ from the usual value of 1\K km/s of integrated CO brightness per $2\times10^{20}$ H2 $\pcc$ . Moreover, the luminosity of diffuse CO viewed perpendicular to the galactic plane is 2/3 that seen at the Solar galactic radius in surveys of CO emission near the galactic plane. Conclusions: Commonality of the CO-H2 conversion factors in diffuse and dark clouds can be understood from considerations of radiative transfer and CO chemistry. There is unavoidable confusion between CO emission from diffuse and dark gas and misattribution of CO emission from diffuse to dark or giant molecular clouds. The character of the ISM is different from what has been believed if CO and H2 that have been attributed to molecular clouds on the verge of star formation are actually in more tenuous, gravitationally-unbound diffuse gas.

However, the origin of the emission observed at low energies is still an open issue. We present a quantitative model for the emission in the optical/infrared band produced by curvature radiation from magnetospheric charges, and compare results with current magnetars observations.

description: We present results for a numerical study of the ghost propagator in Coulomb gauge whereby lattice results for the spatial gluon propagator are used as input to solving the ghost Dyson-Schwinger equation. We show that in order to solve completely, the ghost equation must be supplemented by a boundary condition (the value of the inverse ghost propagator dressing function at zero momentum) which determines if the solution is critical (zero value for the boundary condition) or subcritical (finite value). The various solutions exhibit a characteristic behavior where all curves follow the same (critical) solution when going from high to low momenta until `forced' to freeze out in the infrared to the value of the boundary condition. The boundary condition can be interpreted in terms of the Gribov gauge-fixing ambiguity; we also demonstrate that this is not connected to the renormalization. Further, the connection to the temporal gluon propagator and the infrared slavery picture of confinement is discussed.

description: Using harmonic emission from circularly polarized undulator is a procedure that is normally employed on synchrotron beamlines in order to extend the covered spectral range. A similar capability is likewise beneficial for next generation free-electron lasers. In this paper, we perform a first quantitative experimental analysis of the angular distribution of free-electron laser harmonic emission from helical undulators. Experimental results are compared to those obtained by means of a theoretical model based on the paraxial solution of Maxwell's equations.

It is found that strong refraction of $^3$He in the Hoyle state can be clearly seen in the experimental angular distribution at {\it low} incident energy region as an Airy minimum of the {\it pre-rainbow oscillations}.

description: Many psychological models use the idea of a trace, which represents a change in a person’s cognitive state that arises as a result of processing a given stimulus. These models assume that a trace is always laid down when a stimulus is processed. In addition, some of these models explain how response times (RTs) and response accuracies arise from a process in which the different traces race against each other. In this article, we present a Bayesian hierarchical model of RT and accuracy in a difficult recognition memory experiment. The model includes a stochastic component that probabilistically determines whether a trace is laid down. The RTs and accuracies are modeled using a minimum gamma race model, with extra model components that allow for the effects of stimulus, sequential dependencies, and trend. Subject-specific effects, as well as ancillary effects due to processes such as perceptual encoding and guessing, are also captured in the hierarchy. Predictive checks show that our model fits the data well. Marginal likelihood evaluations show better predictive performance of our model compared to an approximate Weibull model.

The measured activation yield for the 144Sm(gamma,n) reaction is compared with the calculated yield using cross sections from previous photoneutron experiments. The activation yields measured for all disintegration channels 144Sm(gamma,n), (gamma,p) and (gamma,alpha) are compared to the yield calculated by using Hauser-Feshbach statistical models. A new parametrization of the photon strength function is presented and the yield simulated by using the modified photon strength parameters are compared to the experimental data.

description: We construct and investigate Boolean networks that follow a given reliable trajectory in state space, which is insensitive to fluctuations in the updating schedule, and which is also robust against noise. Robustness is quantified as the probability that the dynamics return to the reliable trajectory after a perturbation of the state of a single node. In order to achieve high robustness, we navigate through the space of possible update functions by using an evolutionary algorithm. We constrain the networks to having the minimum number of connections required to obtain the reliable trajectory. Surprisingly, we find that robustness always reaches values close to 100 percent during the evolutionary optimization process. The set of update functions can be evolved such that it differs only slightly from that of networks that were not optimized with respect to robustness. The state space of the optimized networks is dominated by the basin of attraction of the reliable trajectory.

description: We study four dimensional large-N SU(N) Yang-Mills theory coupled to adjoint overlap fermions on a single site lattice. Lattice simulations along with perturbation theory show that the bare quark mass has to be taken to zero as one takes the continuum limit in order to be in the physically relevant center-symmetric phase. But, it seems that it is possible to take the continuum limit with any renormalized quark mass and still be in the center-symmetric physics. We have also conducted a study of the correlations between Polyakov loop operators in different directions and obtained the range for the Wilson mass parameter that enters the overlap Dirac operator.

description: It is of substantial interest to study the effects of genes, genetic pathways, and networks on the risk of complex diseases. These genetic constructs each contain multiple SNPs, which are often correlated and function jointly, and might be large in number. However, only a sparse subset of SNPs in a genetic construct is generally associated with the disease of interest. In this article, we propose the generalized higher criticism (GHC) to test for the association between an SNP set and a disease outcome. The higher criticism is a test traditionally used in high-dimensional signal detection settings when marginal test statistics are independent and the number of parameters is very large. However, these assumptions do not always hold in genetic association studies, due to linkage disequilibrium among SNPs and the finite number of SNPs in an SNP set in each genetic construct. The proposed GHC overcomes the limitations of the higher criticism by allowing for arbitrary correlation structures among the SNPs in an SNP-set, while performing accurate analytic p-value calculations for any finite number of SNPs in the SNP-set. We obtain the detection boundary of the GHC test. We compared empirically using simulations the power of the GHC method with existing SNP-set tests over a range of genetic regions with varied correlation structures and signal sparsity. We apply the proposed methods to analyze the CGEM breast cancer genome-wide association study. Supplementary materials for this article are available online.

description: We report on the successful science verification phase of a new observing mode at the Keck interferometer, which provides a line-spread function width and sampling of 150km/s at K'-band, at a current limiting magnitude of K'~7mag with spatial resolution of lam/2B ~2.7mas and a measured differential phase stability of unprecedented precision (3mrad at K=5mag, which represents 3uas on sky or a centroiding precision of 10^-3). The scientific potential of this mode is demonstrated by the presented observations of the circumstellar disk of the evolved Be-star 48Lib. In addition to indirect methods such as multi-wavelength spectroscopy and polaritmetry, the here described spectro-interferometric astrometry provides a new tool to directly constrain the radial density structure in the disk. We resolve for the first time several Pfund emission lines, in addition to BrGam, in a single interferometric spectrum, and with adequate spatial and spectral resolution and precision to analyze the radial disk structure in 48Lib. The data suggest that the continuum and Pf-emission originates in significantly more compact regions, inside of the BrGam emission zone. Thus, spectro-interferometric astrometry opens the opportunity to directly connect the different observed line profiles of BrGam and Pfund in the total and correlated flux to different disk radii. The gravitational potential of a rotationally flattened Be star is expected to induce a one-armed density perturbation in the circumstellar disk. Such a slowly rotating disk oscillation has been used to explain the well known periodic V/R spectral profile variability in these stars, as well as the observed V/R cycle phase shifts between different disk emission lines. The differential line properties and linear constraints set by our data lend support to the existence of a radius-dependent disk density perturbation.

We find that the rainbow-ladder approximation to the gap and Bethe-Salpeter equations is nonperturbatively exact and moreover, we provide a direct connection between the temporal gluon propagator and the quark confinement potential. Further, we show that only bound states of color singlet quark-antiquark (meson) and quark-quark (SU(2) baryon) pairs are physically allowed.

description: VDZ, IKN and HeidelbergCement (HC) have successfully managed to cool clinker under oxyfuel technology conditions. The innovative oxyfuel clinker cooler prototype has successfully been tested in a HC plant in Hannover. The overall aim of this experimental work was the testing of an oxyfuel clinker cooler in an industrial environment in order to assess its cooling performance (efficiency), as well as the potential impacts of CO2–rich cooling gas on clinker quality. The oxyfuel clinker cooler prototype was designed with a capacity of 80 t/d. During the trials a maximum of 47 t/d clinker has been extracted, which corresponds to 1.5% (1:64 scale) of the clinker production of a reference cement plant (3000 t/d). Despite the experimental challenges, CO2 concentration levels of the cooling medium higher than 70 vol.% have been achieved repeatedly by continuous CO2 supply. No leakages of CO2–rich gas occurred during the trials, which proved the efficiency of the sealings. The testing process parameters were recorded continuously and clinker samples from the cement plant main cooler and from the oxyfuel clinker cooler were taken periodically for further analysis. The lessons learned during the trials will be a valuable input for the design of future industrial scale oxyfuel clinker coolers. The operation of the oxyfuel clinker cooler prototype indicates that boundary zones, such as the cold clinker discharge system, demand special attention regarding minimisation of false air ingress also in industrial scale projects. Moisture content of the recirculated cooling gas was much higher than expected. This was attributed to the experiment conditions and the lack of a condenser in the prototype setup. Unusual layers of up to 2 μm thickness around alite crystals in contact with pores, probably resulting from up to 4% alite decomposition, have been observed in a few analysed clinker samples. However, layer formation could not be correlated with the high CO2 concentrations in the cooling medium alone and further investigations were required. The effect of water (moisture) combined with high CO2 concentration in the cooling gas leading to a limited extent of alite decomposition was further investigated and validated. Also, the absence of negative effects of the layers on cement strength was confirmed by additional laboratory testing.
The effects of acute aerobic exercise on motor skill learning and neurophysiology in healthy older adults
Creators: name: Francisco, Beatrice Alexandra
Publisher: name: University of British Columbia
Year: 2018

description: Aging is associated with a reduced ability to perform motor tasks, as well as a decreased capacity for neuroplastic change and motor skill learning. Evidence in young healthy adults suggests a single session of aerobic exercise can facilitate motor learning and changes in movement-related neurophysiological circuits. However, we do not know whether these effects extend to healthy older adults. The objectives of the present thesis were to examine whether a single session of moderate-intensity aerobic exercise 1) facilitates motor skill acquisition and consolidation, and 2) modulates motor cortical and intracortical circuitry, in healthy older adults. Twenty-two participants (55-75 years old) completed a maximal exercise stress test at least two days prior to all other sessions. Next, participants practiced a motor sequence task after 20-minutes of moderate-intensity cycling or 20-minutes of seated rest, on separate occasions. To assess motor learning, participants performed the motor task 24 hours later at a no-exercise retention test. On a separate day, neurophysiological measures using transcranial magnetic stimulation were obtained at two time-points prior to and two time-points following an acute bout of moderate-intensity cycling. Performing aerobic exercise immediately prior to task practice did not yield any statistically significant differences in measures of motor skill acquisition or consolidation. However, we observed a non-significant trend towards improvements in motor memory consolidation, such that under the exercise condition there were greater improvements in repeated sequences compared to rest. Additionally, we found that after exercise there was an increase in long-interval intracortical inhibition (LICI), which returned to near baseline levels within 30 minutes post-exercise. Overall, these findings suggest that a single bout of moderate-intensity aerobic exercise transiently modulates GABA-B mediated intracortical inhibition in healthy older adults, however, these exercise-induced neurophysiological effects may not necessarily translate to changes in motor behaviour. This work is the first to investigate the efficacy of an acute bout of aerobic exercise in facilitating motor performance and learning, as well as modulating motor cortical and intracortical circuits, in healthy older adults. Further understanding of how exercise influences motor learning and neurophysiology in the aging brain will be critical for the development of potential rehabilitation strategies.

description: We have obtained long-slit, infrared spectra of Jupiter with the Anglo Australian Telescope in the K and H bands at a resolving power of 2260. Using a line-by-line, radiative transfer model with the latest, improved spectral line data for methane and ammonia, we derive a model of the zonal characteristics in the atmosphere of this giant planet. We fit our model to the spectra of the zones and belts visible at 2.1 μm using different distributions of cloud opacities. The modeled spectra for each region match observations remarkably well at K band and in low pressure regions at the H band. Our results for the upper deck cloud distribution are consistent with previous models (Banfield et al.1998) fitted to low resolution, grism spectra. The ability to obtain and model high resolution planetary spectra in order to search for weakly absorbing atmospheric constituents can provide better constraints on the chemical composition of planetary atmospheres.

description: Mass outflows driven by stars and active galactic nuclei are a key element in many current models of galaxy evolution. They may produce the observed black hole-galaxy mass relation and regulate and quench both star formation in the host galaxy and black hole accretion. However, observational evidence of such feedback processes through outflows of the bulk of the star forming molecular gas is still scarce. Here we report the detection of massive molecular outflows, traced by the hydroxyl molecule (OH), in far-infrared spectra of ULIRGs obtained with Herschel-PACS as part of the SHINING key project. In some of these objects the (terminal) outflow velocities exceed 1000 km/s, and their outflow rates (up to ~1200 M_sol/yr) are several times larger than their star formation rates. We compare the outflow signatures in different types of ULIRGs and in starburst galaxies to address the issue of the energy source (AGN or starburst) of these outflows. We report preliminary evidence that ULIRGs with a higher AGN luminosity (and higher AGN contribution to L_IR) have higher terminal velocities and shorter gas depletion time scales. The outflows in the observed ULIRGs are able to expel the cold gas reservoirs from the centres of these objects within ~1E6-1E8 years.

Developing an intelligent assistant for the audit plan brainstorming session
Creators: name: Li, Qiao
Publisher: name: No Publisher Supplied

description: During the initial stages of an audit, audit engagement teams are required to conduct brainstorming sessions to evaluate risk factors and discuss the susceptibility of the entity’s financial statements to material misstatement, either as a result of error or fraud (AICPA 2012). At present, the most commonly used decision support tool for audit plan brainstorming is the checklist (Bellovary and Johnstone 2007), which has shown limitations. Large audit firms have been investing in substantive resources to the utilization of Artificial Intelligence (AI) to take advantage of their past audit experience and industry knowledge (Kokina and Davenport 2017). This dissertation suggests that the latest intelligent assistant technology can be applied in the auditing domain to provide risk assessment decision supports to audit engagement teams during audit plan brainstorming discussions. Firstly, an interactive audit cognitive assistant framework is proposed to provide auditors with information retrieval and risk assessment help. The proposed framework provides a new method of knowledge organization for the audit domain, which potentially develops a knowledge base that stores many auditors’ knowledge and experience in audit risk identification and assessment. Furthermore, a Natural Language Processing (NLP)-based audit plan knowledge discovery system (APKDS) is proposed. By applying NLP techniques, the proposed system can continuously collect auditors’ professional experience and expertise in audit brainstorming discussions and transfer the discussion into classified knowledge for future use. The output of the proposed system can provide insights into how auditors identify and assess risks during the audit plan and how audit decisions are made.Finally, we propose a prototype for the APKDS framework and illustrate the development of important modules in the system. Experimental brainstorming meeting recordings are used as training and testing datasets in model building and training. We demonstrate that the proposed objectives of the system can be realized and the proposed system can provide effective decision-making support to auditors. In the end, we proposed the potential application of the audit cognitive assistant to other audit phases.
Measurement of Charm and Beauty Jets in Deep Inelastic Scattering at HERA
Creators: name: H1 Collaboration

Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: Measurements of cross sections for events with charm and beauty jets in deep inelastic scattering at HERA are presented. Events with jets of transverse energy E_T^jet > 6 GeV and pseudorapidity -1.0 < eta^jet < 1.5 in the laboratory frame are selected in the kinematic region of photon virtuality Q^2 > 6 GeV^2 and inelasticity variable 0.07 < y < 0.625. Measurements are also made requiring a jet in the Breit frame with E_T^*jet > 6 GeV. The data were collected with the H1 detector in the years 2006 and 2007 corresponding to an integrated luminosity of 189 pb^-1. The numbers of charm and beauty jets are determined using variables reconstructed using the H1 vertex detector with which the impact parameters of the tracks to the primary vertex and the position of secondary vertices are measured. The measurements are compared with QCD predictions and with previous measurements where heavy flavours are identified using muons.

description: The demand side plays a pivotal role in order to understand the expanse of the whole energy system, especially when one considers the European Union’s (EU) commitment to climate neutrality by 2050, in the context of which, energy demand needs to be reduced substantially. Therefore, the role of policies that support energy efficiency measures and demand-side management practices will be critical; however, the impacts of such policies can only be explored ex-ante using energy demand models. In this context, the energy demand models (EDMs) used in the Sustainable Energy Transitions Laboratory (SENTINEL) project provide yearly and hourly future demand profiles for each of the EU Member States. However, EDMs, including the ones used in SENTINEL, namely: BEVPO, DESSTINEE, DREEM, and HEB, are often criticized for not incorporating dynamic GDP, or socio-political dimensions. Having that in mind, the SENTINEL EDMs will be soft-linked with the QTDIAN toolbox from WP2 to incorporate storylines of different socio-political developments, while calculating the future energy demand. Furthermore, the SENTINEL EDMs use a linear economic (mainly GDP) projection as input data to calculate future energy demand profiles. However, the linear projection of economic input usually excludes market uncertainties, and hence, makes model outputs less realistic. To overcome this limitation in SENTINEL, EDMs will be also soft-linked with the macroeconomic model WEGDYN from WP5. This soft-linking will make the output of the SENTINEL EDMs much more realistic, and, hence, it is expected to increase their useability in decision-making. Thus, the demand profiles, more precisely the hourly and yearly demand profiles for the building, transport and industry sectors, will be used in WP4 as an input to calculate the energy balance in the context of the transition to climate neutrality in the EU. Finally, to make these exercises more policy relevant, all the aforementioned soft-linkages will take place for three case studies of different heterogeneous geographical scales and policy characteristics, namely: a. Greece (National level), b. Nordic countries (Regional level), and c. EU, Switzerland, and United Kingdom (Continental level). These case studies will serve as the testing ground to demonstrate the applicability of the SENTINEL EDMs, test their usefulness for potential end-users, and provide policy-relevant answers to different research questions, as identified in WP7. Overall, this report documents the technical details of the WP3–related soft-linking activities in SENTINEL and further discusses the expected impact of their application to the three case studies.
Zooplankton community composition across a range of productivity regimes in coastal British Columbia

description: Coastal British Columbia is composed of deep channels and shallow sills intricately woven around a collection of small islands, creating complex oceanographic conditions. Consequently, seasonal production varies up to several orders of magnitude throughout the region, with some regions undergoing large annual phytoplankton blooms, while others have permanently low phytoplankton biomass. The region from the northern Strait of Georgia (SoG) to Johnstone Strait (JS) has been vastly understudied from the perspective of zooplankton despite its importance to many higher trophic levels. The objectives of this study were to: a) describe the annual seasonal cycle of zooplankton in the northern SoG over the course of two years and examine how communities differed, and b) examine the spatial patterns in zooplankton community composition and abundance from the northern SoG to JS, a region spanning seasonally productive / stratified areas (northern SoG, eastern Discovery Islands (DI)) as well as permanently high-nutrient, low-chlorophyll (HNLC) regions (JS, western DI). There was a strong signal of intra-annual seasonality in zooplankton community dynamics in the northern SoG, separating into distinct winter, early spring, and summer – fall assemblages. Despite a six week difference in spring bloom timing between years, peak zooplankton abundance occurred within the same calendar week during both years and community composition was similar between years, indicating that there is likely resilience within the zooplankton seasonal cycle to short scale interannual changes in environmental conditions. Our spatial analysis indicated that the northern SoG, DI, and JS each had distinct zooplankton communities with key species and densities separating regions. We detected minimal overlap in the JS zooplankton community with the DI and northern SoG, indicating that while DI zooplankton are likely sourced from the SoG, JS zooplankton likely originate from Queen Charlotte Sound. The DI were comprised of both productive and HNLC regions, yet zooplankton abundance was highest in the mixed western DI channels. Intense tidal mixing in the DI likely supplies nutrients to stratified surface waters in the eastern DI, which in turn supply zooplankton to the western DI with low in-situ production. These results provide insight into how feeding conditions for higher trophic levels may vary throughout the region.
