description: This contribution focuses at appropriate IT structures for innovative market segments which form an application environment that is only fundamentally defined in digitization efforts. The core feature are vague application profiles for IT structures to be set up, which players in such market segments can use internally, but especially in environmental and social interaction. For the example of the emerging blue bioeconomy, experiences in setting up a cross-location, distributed IT structure are presented, which is geared towards advising and supporting actors in the blue bioeconomy by a diverse team of experts. Key findings lie in (i) the need to integrate different dimensions of vagueness in the treatment of increasingly defined information in a three-layer model of the IT structure, (ii) the development of the IT structure in an open process that takes into account the dynamics of the market sector, and (iii) the constant training of the members of the expert team on content, routines and limitations of the IT structure in consulting of actors.
Radiative Signatures of Relativistic Shocks

description: (Abbreviated) Particle-in-cell simulations of relativistic, weakly magnetized collisionless shocks show that particles can gain energy by repeatedly crossing the shock front. This requires scattering off self-generated small length-scale magnetic fluctuations. The radiative signature of this first-order Fermi acceleration mechanism is important for models of both the prompt and afterglow emission in gamma-ray bursts and depends on the strength parameter "a" of the fluctuations. For electrons (and positrons), acceleration saturates when the radiative losses produced by the scattering cannot be compensated by the energy gained on crossing the shock. We show that this sets an upper limit on both the electron Lorentz factor and on the energy of the photons radiated during the scattering process. This rules out "jitter" radiation on self-excited fluctuations with a < 1 as a source of gamma-rays, although high-energy photons might still be produced when the jitter photons are upscattered in an analog of the synchrotron self-Compton process. In fluctuations with a > 1, radiation is generated by the standard synchrotron mechanism, and the maximum photon energy rises linearly with a, until saturating at approximately 70 MeV.

description: In the pursuit of fighting the climate catastrophe several technologies promise to help creating sustainable societies. In the digital realm a supposedly revolutionary set of technologies called artificial intelligence (AI) is currently discussed as tool for reaching ecological sustainability. Ecologically oriented AI applications like data analysis and monitoring as well as decision automation have been the subject of research for some time, and recently, the ecological footprint of AI systems themselves started to come into focus too.
On a different note and shifting the focus to social sustainability, the societal implications of AI applications directly affecting individuals and groups are widely discussed in terms of fairness, accountability and transparency as well as regarding ethics and regulation. However, ecologically oriented AI applications also do have societal implications, although they are often less obvious, partly because of the ecological focus and purpose, and partly because of the usually more indirect relation. This paper intents to close this gap by suggesting an appropriate general societal impact analysis grid and by applying this grid on the concrete use case of satellite-data driven Earth Observation (EO).
This approach is fruitful in two ways: First, our suggested societal impact analysis grid extends existing technology impact assessment frameworks (like the rather general Matrix of Convivial Technology) with critical social theory aspects (e.g. fairness, inequality), and data protection theory aspects (e.g. information power asymmetries). With this extension the grid is especially applicable to societal implications of computational and data-related technologies like AI. Second, we exemplify the use of our analysis grid on the case of EO and therefore uncover societal implications not evident upon first sight.
Within its purpose EO provides practical benefits illustrating the potential of AI in contributing valuable sustainability-related insights, e.g. environmental monitoring. However, applying our grid, societal issues do emerge, e.g. a critical observer-observed relationship or global structural unfairness concerning available data. In creating the impact grid and discussing the concrete case of EO, this paper contributes to a needed and growing scholarship of sustainable AI.

description: A formula for the two-loop infrared singularities of dimensionally regularized QCD scattering amplitudes with an arbitrary number of massive and massless legs is derived. The singularities are obtained from the solution of a renormalization-group equation, and factorization constraints on the relevant anomalous-dimension matrix are analyzed. The simplicity of the structure of the matrix relevant for massless partons does not carry over to the case with massive legs, where starting at two-loop order new color and momentum structures arise, which are not of the color-dipole form. The resulting two-loop three-parton correlations can be expressed in terms of two functions, for which some general properties are derived. This explains observations recently made by Mitov et al. in terms of symmetry arguments.

description: This research work demonstrates the potential of material and energy flow analysis (MEFA) digital tool to address sustainability concerns in Semi-automated production lines in SMEs. The paper presents the application of MEFA on a solar panels’ assembly facility in the MENA region. The importance of thorough data collection is highlighted as it allows for accurate mapping of how materials and energy are flowing through a system especially in case of manual assembly lines. The challenges in data acquisition are addressed and the improvement scenarios are presented by using simple innovative methods such as QR codes to streamline the data collection process, saving time and reducing errors. Overall, this paper demonstrates how material and energy flow modelling can be used to identify areas for improvement in sustainability practices in small and medium enterprises using simple digital tools.

description: We shortly review the statistical properties of the escape times, or hitting times, for stock price returns by using different models which describe the stock market evolution. We compare the probability function (PF) of these escape times with that obtained from real market data. Afterwards we analyze in detail the effect both of noise and different initial conditions on the escape time in a market model with stochastic volatility and a cubic nonlinearity. For this model we compare the PF of the stock price returns, the PF of the volatility and the return correlation with the same statistical characteristics obtained from real market data.

description: Questions What are the long-term patterns of wildfire occurrence and gap dynamics in an old-growth deciduous forest? Are there temporal patterns in fire and gap dynamics over the last ca. 300 yrs? How is drought related to fire occurrence? Are there temporal interactions between gap dynamics and fire? Location Lilley Cornett Woods Appalachian Research Station, Southeastern Kentucky, USA. LCW; 37°05′ N, 83°00′ W. Methods We cross-dated and analysed annually-resolved tree-ring data from 35 tree cross-sections in an old-growth deciduous forest to reconstruct historical fire and canopy disturbance and explore connections among these processes. Canopy disturbance patterns as indicated by tree growth release within this collection [fire history collection: (FHC)] were compared to cores from 26 trees collected in 1983 for the purposes of climate reconstruction [climate collection: (CC)]. Results Initiation dates in the FHC ranged from ca. 1670 to 1925. Thirty-three fire scars were identified from 1678 to 1956. The mean interval between fire events was 9.3 yrs, and there were many more fires after 1800 than before that date. Gap dynamics, as reconstructed through growth release detection, were relatively constant through the FHC record and were supported by a similar result in the CC. The mean number of years between detected release events was 5.2 yrs. Many individual trees, and the mean growth chronology for the FHC, indicate that many oak trees exhibit growth release after long periods of suppression and, after a final release, exhibit a step-change in growth rate suggesting canopy accession. Conclusions Fire and gap dynamics occurred through much of the last ca. 350 yrs in this old-growth forest. There was not evidence to support that these two processes were temporally linked – gap dynamics were ostensibly independent of fire occurrence. Even so, we posit that these two processes may have a synergistic effect on long-term dynamics, wherein fire ‘filters’ the seedling pool and gap openings provide canopy accession opportunities. We also note several instances where release events are associated with stand-wide growth increases suggesting large-scale canopy accession. These events could influence the overstorey composition of the forest for centuries.

title: Software Life Cycle Assessment (SLCA) in the wild
Creators: name: Hoffmann, Geerd-Dietger
name: Tarara, Arne
Publisher: name: Gesellschaft für Informatik e.V.
Year: 2023

description: Software Life Cycle Assessment (SLCA) is a critical topic gaining increasing attention due to the environmental impacts of software production, deployment, usage, and disposal. While Life Cycle Assessment (LCA) is well-established in the context of physical products, SLCA is still an evolving field in the software industry. This talk will present a simple and practical approach to conducting a Software Life Cycle Assessment for a piece of code, along with discussions on important concepts and tradeoffs for smaller projects. While a physical product has a clear status in relation to the LCA software is ever evolving and is constantly changed and redeployed. Hence a new approach is needed to the point in time evaluation. The concept of a transparency platform is introduced which accounts for the ever changing nature of software while enforcing the highest standards in software measurement and traceability.
The SLCA process outlined here involves analyzing the various phases of software development, deployment, usage, and disposal to identify potential environmental impacts and sustainability issues. In the development phase, the speaker will share their journey of measuring the environmental impact of their development activities, highlighting the challenges and assumptions made to estimate energy consumption accurately. He proposes the concept of a Software Carbon Database, where energy usage data is collected and stored, enabling continuous assessment of software’s environmental impact. The talk will emphasize the need for a standardized database format to account for all aspects of the software’s life cycle and explains the purpose of the Software Carbon Database in this context. The deployment phase is briefly touched upon, focusing on the energy consumed during a simplified Docker build.
Addressing the complexities of estimating usage phase impacts, the talk will argue that modern software is continuously evolving, making it challenging to predict and measure usage accurately. To overcome this, the author introduces a middleware solution that tracks energy usage per API call and updates the Software Carbon Database in real-time, providing a more accurate and dynamic assessment.
Lastly, the disposal phase is considered, with the author using the Green Metrics Tool to measure the energy consumed during the removal of software components.
In conclusion, this talk will present a pragmatic and contemporary approach to Software Life Cycle Assessment, designed to fit the agile and rapidly evolving nature of modern software development. The proposed methodology relies on real-life data, offers traceability, and can be easily adopted by development teams to promote sustainable software practices. Lastly we will discuss recommendations to improve data quality for the disposal and delivery phase, which are typically handled by service providers at the moment.

description: This thesis describes research performed by myself, Simon Foote, from the completion of my PhD until the date of submission. The research was performed in three separate Institutes. The early work describing the mapping of the Human Genome and the preceding, introductory project mapping the Human Y Chromosome was performed at the Whitehead Institute, MIT, Cambridge, USA. This work was done in the laboratories of Professors David Page and Eric Lander. The work describing the host responses to infectious disease and the genetics of susceptibility to multiple sclerosis was performed in my own laboratory at the Walter and Eliza Hall Institute (WEHI), Melbourne, Australia and more recently at the Menzies Research Institute, University of Tasmania, Hobart, Australia. This introductory chapter is not a review of the literature, but a synopsis of the work attached as copied, published articles. The state of play of the field at the time of publication of each of these articles can be found in the introduction and discussion of each of these papers. While this collection of papers may seem eclectic at first perusal, there is a strong genetics theme underpinning all these topics.

description: We have been analyzing a large sample of solar-like stars with and without planets in order to homogeneously measure their photospheric parameters and Carbon abundances. Our sample contains around 200 stars in the solar neighborhood observed with the ELODIE spectrograph, for which the observational data are publicly available. We performed spectral synthesis of prominent bands of C$_{2}$ and C I lines, aiming to accurately obtain the C abundances. We intend to contribute homogeneous results to studies that compare elemental abundances in stars with and without known planets. New arguments will be brought forward to the discussion of possible chemical anomalies that have been suggested in the literature, leading us to a better understanding of the planetary formation process. In this work we focus on the C abundances in both stellar groups of our sample.

description: The effects of extreme weather events are increasingly having a negative impact on the water and wastewater infrastructure. Due to increasing land sealing in urban areas and more intense rain events, new concepts are needed to relieve the water and wastewater infrastructure. One possible approach is the usage of private rain storage as retention volume without negatively affecting the owner. Therefore, a smart approach is used to manage the rain storage in a situational way. This paper therefore presents a first prototype of a smart water tank, which was used to cover and test initial requirements. The goal was to develop an operational and portable hardware and software prototype early in the project.

Entanglement in the anisotropic Heisenberg XYZ model with different Dzyaloshinskii-Moriya interaction and inhomogeneous magnetic field

description: We investigate the entanglement in a two-qubit Heisenberg XYZ system with different Dzyaloshinskii-Moriya(DM) interaction and inhomogeneous magnetic field. It is found that the control parameters ($D_{x}$, $B_{x}$ and $b_{x}$) are remarkably different with the common control parameters ($D_{z}$,$B_{z}$ and $b_{z}$) in the entanglement and the critical temperature, and these x-component parameters can increase the entanglement and the critical temperature more efficiently. Furthermore, we show the properties of these x-component parameters for the control of entanglement. In the ground state, increasing $D_{x}$ (spin-orbit coupling parameter) can decrease the critical value $b_{xc}$ and increase the entanglement in the revival region, and adjusting some parameters (increasing $b_{x}$ and $J$, decreasing $B_{x}$ and $Δ$) can decrease the critical value $D_{xc}$ to enlarge the revival region. In the thermal state, increasing $D_{x}$ can increase the revival region and the entanglement in the revival region (for $T$ or $b_{x}$), and enhance the critical value $B_{xc}$ to make the region of high entanglement larger. Also, the entanglement and the revival region will increase with the decrease of $B_{x}$ (uniform magnetic field). In addition, small $b_{x}$ (nonuniform magnetic field) has some similar properties to $D_{x}$, and with the increase of $b_{x}$ the entanglement also has a revival phenomenon, so that the entanglement can exist at higher temperature for larger $b_{x}$.

description: By incorporating a large-scale shear flow into turbulent rotating convection, we show that a sufficiently strong shear can promote dynamo action in flows that in the absence of shear do not act as dynamos. Our results are consistent with a dynamo driven by either the shear-current effect or by the interaction between a fluctuating $α$-effect and the velocity shear; they are though inconsistent with either a classical $α^2$ or $αω$ mean field dynamo.

description: We investigate a possibility of precision measurements for parameters of the Littlest Higgs model with T-parity at the International Linear Collider (ILC). The model predicts new gauge bosons (AH, ZH, and WH), among which the heavy photon (AH) is a candidate for dark matter. The masses of these new gauge bosons strongly depend on the vacuum expectation value that breaks a global symmetry of the model. Through Monte Carlo simulations of the processes: e+ e- ->AH ZH and e+ e- -> WH+ WH-, we show how precisely the masses can be determined at the ILC for a representative parameter point of the model. We also discuss the determination of the Little Higgs parameters and its impact on the future measurement of the thermal abundance of the dark matter relics in our universe.

description: In the Internet of Things (IoT), many devices are battery-operated, making them particularly susceptible to power-hungry applications. Symmetric encryption is a regularly performed task on such devices, as it ensures the confidentiality of the data they send. While previous work has compared the power consumption of common symmetric encryption algorithms on commodity hardware, no such evaluation exists for low-cost microchips, which are often used in IoT devices. In this paper, we compare the power consumption of an ESP8266 executing common symmetric encryption algorithms with varying parameters such as key size, data authentication, or payload size. We find that the power consumption depends on several factors, but that overall AES-GCM has the lowest power consumption when the encrypted data is also authenticated, while Blowfish-CTR has the lowest power consumption when no authentication is applied.

title: Eco-innovation performance in European Union
Creators: name: Bartoszczuk, Pawel
Publisher: name: Gesellschaft für Informatik e.V.
Year: 2023

description: To date no uniform proposal for measuring and analysing eco-innovation in the literature has been emerged. The main challenges in this regard are the need to establish indicators at micro level, taking into account the life cycle and the separation of eco- efficiency from the economic category of eco-innovation, the definition of levels of eco- innovation analysis and the careful development of data aggregation methods, in addition to understanding the effect of eco-innovation and the relationship of eco-innovation indicators to key indicators for measuring sustainable and sustainable socio-economic development. The effects of eco-innovation can be measured on a micro scale (for product or service, process, enterprise), meso (sector,) and macro. The effects of eco-innovation cannot be always positive. Despite the high investment of companies, eco-innovation activities are producing results in the longer term on a micro scale by reducing the negative impact of its activities on the environment, while at the same time leading to the impact of eco-innovation on the company's performance in the form of lower environmental pollution charges and lower energy costs. The main goal of the article is to prove the thesis that eco-innovation allows countries’ economies to increase their performance in the longer time period. Another aim was to analyse eco-innovation scoreboard data and to unveil the low index value reasons for Central Europe countries. To gain so declared goals, a research question was formulated as follow: do countries with less developed economies have lower eco-innovation performance? The performance measurement was based on secondary data analysis obtained from Eco-innovation observatory. These basic indicators and trends described European countries’ eco-innovations performance. The analysis is based on comparative research and available data. Poland is in the low eco-innovation performance group of countries, as are most Eastern European countries and some Western countries (such as Malta). Even against the background of these countries, there is a great distance of Poland to the new member states e.g. the Czech Republic and Estonia. The results of these indices indicate insufficient implementation of eco-innovation in enterprises in Poland. Currently available data presented by the European Eco-innovation Observatory confirms a significantly insufficient degree of eco-innovation of the Polish economy. On the one hand, there is no pressure on research in new eco-innovative solutions. On the other, academic and R&D centers are unable to satisfy the demands of the industry. It is of key importance that eco-innovations are perceived as the driving factor of the third transformation in Poland and other EU new members (following system transformation and the EU accession).
Cell processor implementation of a MILC lattice QCD application

description: We present results of the implementation of one MILC lattice QCD application-simulation with dynamical clover fermions using the hybrid-molecular dynamics R algorithm-on the Cell Broadband Engine processor. Fifty-four individual computational kernels responsible for 98.8% of the overall execution time were ported to the Cell's Synergistic Processing Elements (SPEs). The remaining application framework, including MPI-based distributed code execution, was left to the Cell's PowerPC processor. We observe that we only infrequently achieve more than 10 GFLOPS with any of the kernels, which is just over 4% of the Cell's peak performance. At the same time, many of the kernels are sustaining a bandwidth close to 20 GB/s, which is 78% of the Cell's peak. This indicates that the application performance is limited by the bandwidth between the main memory and the SPEs. In spite of this limitation, speedups of 8.7x (for 8x8x16x16 lattice) and 9.6x (for 16x16x16x16 lattice) were achieved when comparing a 3.2 GHz Cell processor to a single core of a 2.33 GHz Intel Xeon processor. When comparing the code scaled up to execute on a dual-Cell blade and a quad-core dual-chip Intel Xeon blade, the speedups are 1.5x (8x8x16x16 lattice) and 4.1x (16x16x16x16 lattice).

description: We have reconstructed the Oligocene to Middle Miocene paleobathymetry and stratigraphy of the New Jersey margin using a modified backstripping technique. By analyzing the geometry of the margin through time, we investigate its response to fluctuating sea level, changing climate, and variable sediment supply during the Tertiary. The reconstructions reveal a change in the margin morphology from a more steeply dipping (1 : 300 to 1 : 500) carbonate ramp in the Eocene to a flatter shelf with a sharp shelf edge at present. This was accomplished by an increase in the terrigenous sediment supply that filled available accommodation and caused progradation across the margin. We link the increase in sediment flux with climatic cooling rather than tectonic processes. The progradation is evidenced by a series of clinoforms whose formation was modulated by sea level and which extend over 100 km across the shelf. The height and dip of the clinoforms increased as they extended onto the deeper parts of the earlier ramp. The Miocene clinoform rollovers at the New Jersey margin had water depths of ∼60–130 m and are interpreted as the edge of a new continental shelf built over the older ramp. Sea-level fall was probably insufficient to drive the Miocene shorelines past the shelf breaks. Thus, measurements of sea-level amplitude based upon `coastal' onlap over the clinoforms are not reliable.

description: This paper compares the energy and resource efficiency between MATLAB and R, two widely used programming languages in scientific computing and data analysis. A load driver and automation software, Power Automate, were utilized as a system under test to measure and evaluate the performance of both languages. Before the experiment, specific mathematical operations and execution methods were developed in MATLAB and R scripts. The measurement and evaluation were conducted using the Oscar framework. The results indicate that R outperforms MATLAB in baseline and statistical operations, while MATLAB excels in matrix calculations. These findings provide valuable insights for selecting the most suitable programming language based on specific computational requirements, optimizing energy consumption and resource utilization.

description: We briefly review analytic approximations of thermodynamic functions of fully ionized nonideal electron-ion plasmas, applicable in a wide range of plasma parameters, including the domains of nondegenerate and degenerate, nonrelativistic and relativistic electrons, weakly and strongly coupled Coulomb liquids, classical and quantum Coulomb crystals. We present improvements to previously published approximations. Our code for calculation of thermodynamic functions based on the reviewed approximations is made publicly available.

description: We discuss various aspects of `braid spaces' or configuration spaces of unordered points on manifolds. First we describe how the homology of these spaces is affected by puncturing the underlying manifold, hence extending some results of Fred Cohen, Goryunov and Napolitano. Next we obtain a precise bound for the cohomological dimension of braid spaces. This is related to some sharp and useful connectivity bounds that we establish for the reduced symmetric products of any simplicial complex. Our methods are geometric and exploit a dual version of configuration spaces given in terms of truncated symmetric products. We finally refine and then apply a theorem of McDuff on the homological connectivity of a map from braid spaces to some spaces of `vector fields'.

description: We study cold fermionic atoms using the holographic principle. We note that current atomic experiments with massive fermions trapped in a harmonic potential in the unitarity limit behave as massless fermions thanks to the Thomas-Fermi approximation. We map the thermodynamics of strongly correlated massless fermion to that of the charged black hole and study the thermodynamics and transport properties of cold fermions at strong coupling at finite temperature and density. In cold limit, the specific heat of charged black hole is linear in $T$ independent of the dimensionality, which is reminiscent of Fermi liquids. The shear viscosity per particle is shown to be finite as a consequence of the non-vanishing of the entropy. We show that our holographic results compare favorably with most of the current atomic data.

description: We perform the first analysis of stratosphere-troposphere exchange in terms of distributions that partition the one-way flux across the thermal tropopause according to stratospheric residence time τ and the regions where air enters and exits the stratosphere. These distributions robustly quantify one-way flux without being rendered ill defined by the short-τ eddy-diffusive singularity. Diagnostics are computed with an idealized circulation model with topography only in the Northern Hemisphere (NH) run under perpetual NH winter conditions. Suitable integrations of the flux distribution are used to determine the stratospheric mean residence time inline image and the mass fraction of the stratosphere in any given residence time interval. We find that the largest mass fraction is destined for isentropic cross-tropopause transport, with one-way fluxes that are sustained over a broad range of residence times. Air exiting the stratosphere in the winter hemisphere has significantly longer mean residence times than air exiting in the summer hemisphere because the winter hemisphere has a deeper circulation and stronger eddy diffusion. We also explore the sensitivity of the stratosphere-troposphere exchange to changes in the circulation by increasing the amplitude of the topography. The resulting more vigorous residual mean circulation dominates over increased eddy diffusion, leading to decreased inline image except for air exiting at high NH latitudes, for which inline image increases. These findings underline that the flux distributions diagnose the integrated advective-diffusive tropopause-to-tropopause transport and not merely advection by the residual mean circulation.
title: Towards Fine-Grained Sensor-Based Probabilistic Individual Air Pollution Exposure Prediction using Wind Information

description: The estimation of pollutant exposure is highly dependent on the spatial and temporal resolution of the underlying model. This work presents a street-level Gaussian Process Regression model for urban air quality that uses a novel covariance kernel based on physical considerations to process wind information. This model can be driven by information from observations from low-cost sensor networks. We present the model, including the construction of the wind angle kernel, and discuss the inconclusive evaluation to date, the current challenges, and the way forward.

description: © 2020 World Health Organization; licensed by IAS. Introduction: As adolescents transition from childhood to adulthood, they experience major physical, social and psychological changes, and are at heightened risk for developing mental health conditions and engaging in health-related risk behaviours. For adolescents living with HIV (ALHIV), these risks may be even more pronounced. Research shows that this population may face additional mental health challenges related to the biological impact of the disease and its treatment, the psychosocial burdens of living with HIV and HIV-related social and environmental stressors. Discussion: Psychosocial interventions delivered to adolescents can promote positive mental health, prevent mental health problems and strengthen young people’s capacity to navigate challenges and protect themselves from risk. It is likely that these interventions can also benefit at-risk populations, such as ALHIV, yet there is little research on this. There is an urgent need for more research evaluating the effects of interventions designed to improve the mental health of ALHIV. We highlight four priorities moving forward. These include: generating more evidence about preventive mental health interventions for ALHIV; including mental health outcomes in research on psychosocial interventions for ALHIV; conducting intervention research that is sensitive to differences among ALHIV populations and involving adolescents in intervention design and testing. Conclusions: More robust research on promotive and preventive mental health interventions is needed for ALHIV. Programmes should be informed by adolescent priorities and preferences and responsive to the specific needs of these groups.
