description: Für Cloud-Kund*innen ergeben sich durch die Nutzung von Cloud-Computing-Diensten verschiedene Vorteile. So entfallen beispielsweise die Kosten für den Betrieb einer eigenen IT-Infrastruktur, und der Umfang der genutzten Ressourcen kann je nach Bedarf flexibel angepasst werden. Die Nutzung von Cloud-Computing-Diensten bringt allerdings auch Risiken mit sich.
description: We present a structured method for
performing risk analysis for cloud
applications according to the ISO
27001 standard. Our method relies
on patterns to describe the context
and structure of a cloud computing
system (using CSAP), to identify
threats, to elicit the security requirements,
and to select controls. Our
ClouDA tool supports the application
of this method. Our approach
delivers the following main benefits:
• Systematic pattern-based identification
of threats using threat patterns
and their relationship to CSAP
elements, which facilitates and accelerates
the threat analysis
• Systematic pattern-based identification
of security requirements to be
fulfilled by appropriate controls
using security requirement patterns
and their relationship to threat patterns
• Systematic pattern-based identification
of controls using their relationship
to security requirement
patterns
• Tool support for our approach
• Increased effectiveness of risk analysis
by applying the method and
reduced documentation effort by
hierarchical refinement of assets.
In the future, we want to extend the
tool for supporting other types of
patterns for performing risk analysis.
In addition, we intend to enrich the
tool so as to check the complete and
coherent instantiation of the patterns.

description: Aim: First use of opioids often happens in adolescence and an increasing number of opioid overdoses are being reported among youth. The purpose of this narrative review was to pre-sent the treatment approaches for youth with high-risk opioid use, determine whether the lit-erature supports the use of opioid agonist treatment among youth, and identify evidence for better treatment outcomes in the younger population. Methods: A search of the literature on PubMed® using MeSH terms specific to youth, opi-oid use, and treatment approaches generated 1,436 references. Following a screening process, 137 papers were found to be relevant to the treatment of high-risk opioid use among youth. After full-text review, 19 eligible studies were included: four randomized controlled trials, nine observational studies, and six reviews. Results: Research for the different treatment options among youth is limited. The available evidence shows better outcomes in terms of retention in care and cost-effectiveness for opioid agonist treatment than abstinence-based comparisons. Integrating psychosocial interventions into the continuum of care for youth can be an effective way of addressing comorbid psychi-atric conditions and emotional drivers of substance use, leading to improved treatment trajec-tories. Conclusions: From the limited findings, there is no evidence to deny youth with high-risk opioid use the same treatment options available to adults. A combination of pharmacological and youth-specific psychosocial interventions is required to maximize retention and survival. There is an urgent need for more research to inform clinical strategies towards appropriate treatment goals for such vulnerable individuals.

description: Why does chemistry need large
computers? Because the interactions
between individual atoms and molecules
determine the behavior of
chemical systems, and because the
numerical calculation of these interactions
is difficult and numerically
expensive. Computer simulations of
these interactions form one of the
pillars of modern natural sciences.
Computers are particularly useful
when it comes to disordered systems
such as liquids and solutions in
which hierarchical processes of selforganization
take place on different
time and length scales. A current
research project of our group is the
study of the formation and fusion of
so-called micelles (which are, in
36
turn, self-assembled structures in
aqueous solutions composed of
many molecules with a hydrophilic
(water-loving) and a hydrophobic
(water-hating) end) into cylindrical
and three-dimensional entities. The
dependence of this behavior on small
ions with specific activity offers the
potential to manipulate the shape
and dynamics of the micellar systems
themselves. Instrumental and essential
for such studies is the use of
computer systems of varying computational
power, which we demonstrate
on the basis of our experience
with the performance of server PCs
in our group and the supercomputers
CRAY-XT6m and NEC-magnitUDE
at the Center of Computational
Sciences and Simulation at our
university.

description: Die möglichst akkurate Vorhersage des Strömungsverhaltens von Fluiden ist nach wie vor eine der größten Herausforderungen der Ingenieurwissenschaften. Hier setzt die Arbeitsgruppe von Andreas Kempf an.
description: The accurate prediction of fluid flows is still one of the most challenging engineering problems. This is due to the turbulent nature of fluid flows that can only be resolved by numerical simulations for small and simplified problem sizes, even with the massive computational resources that are available today. When chemical reactions and combustion processes are involved, the computational costs become even larger due to the stiff and non-linear interaction between turbulence and chemistry. Therefore, reduction techniques have been developed in the past, namely the Reynolds averaged Navier-Stokes (RANS) and the large-eddy simulation technique (LES). The latter has the potential to describe the turbulent combustion process more precisely, but still requires models for the unresolved turbulent scales. These models are developed in the group of Prof. Kempf at the University of Duisburg- Essen, where a broad range of applications is covered. Examples are the combustion of coal, the synthesis of nano-particles in flames, and the combustion processes in internal combustion engines. To perform the required simulations on the largest supercomputers in the world, the group has developed its own inhouse code that is suitable for massively parallel simulations.

description: Mit Hilfe der Dichtefunktionaltheorie sind wir in der Lage, den Zusammenhang zwischen der atomaren Struktur und den Eigenschaften eines Materials zu erforschen, ohne dass empirisch gewonnene Kenntnisse als Ausgangspunkt benötigt werden. Der Einsatz von High-Performance Computing ermöglicht es uns, diesen parameterfreien wissenschaftlichen Zugang sogar auf komplexe Systeme, zum Beispiel Grenzflächen zwischen zwei Materialien, auszudehnen.
description: Density functional theory puts us in
position to investigate the relationship
structure-propertty in materials
without having to rely on empirical
input. The usage of high performance
computing enables us to
extend this parameter-free approach
to complex atomic structures that are
encountered for instance at interfaces
between two materials. We are thus
in position to carry out computeraided
explorative studies of diverse
materials combinations, and to tailor
the materials properties to specific
envisaged applications. Several such
applications from the field of spintronics
have been presented:
For the spin transistor, a magnetic
material compatible with silicon is
sought for, and we managed to identify
manganese silicide as one candidate.
For the spin valve and for thermal
spin injection, we explored ferromagnetic
half metals and identified
double layer structures of Heusler
alloys as promising. As a future goal,
we aim at enhancing the predictive
power of our approach by including
dynamical materials properties into
our modelling. Examples are oscillations
of the atoms around their equilibrium
positions as well as spin
waves in magnetic materials, both of
which have an impact on the temperature
dependence of the electrical
resistivity.

description: La presencia de animales antropomorfizados tiene una larga tradición en el arte y sobre todo en la literatura - sea oral, sea escrita - de casi todas la culturas. Entre los escritores modernos que se han valido con éxito de este elemento estilístico hay sin duda el rioplatense Horacio Quiroga, en cuya obra los animales tienen muy a menudo un papel protagónico y están representados con rasgos, actitudes y peculiaridades estrictamente humanas. El presente estudio (presentado al Coloquio Internacional “El bestiario de la literatura latinoamericana” organizado en octubre de 2009 por la Universidad de Poitiers) propone un análisis del las heterogéneas modalidades de los procesos de antropomorfización de los animales a los cuales el escritor recurre en sus cuentos ambientados en la dimensión de la naturaleza salvaje del Chaco y de Misiones y sobre todo en los textos destinados a los jóvenes lectores, relatos breves que están caracterizados por una presencia marcada del elemento fantástico.

description: Persönliche Daten in der Cloud zu speichern und zu verarbeiten, kann ein Risiko sein, wenn die Daten vor Manipulation und unerlaubtem Zugriff nicht sicher sind. Spätestens seit der NSA-Affäre interessiert die Nutzer*innen: Wer besitzt meine Daten? Wer kann darauf zugreifen? Was passiert bei deren Verarbeitung und Auswertung? Wissenschaftler*innen am paluno (The Ruhr Institute for Software Technology) der Universität Duisburg-Essen arbeiten an softwaretechnischen Lösungen zur sicheren Datenverarbeitung beim Cloud Computing.
description: Cloud computing has many benefits
for service providers and service
users alike. However, by storing and
processing data in the cloud, users
lose control over their data. The data
security breaches that became publicly
known in the last couple of
years have shown that this is a real
threat that can hinder the adoption
of cloud computing, especially in
domains with strong data security
requirements.
Researchers at paluno (The Ruhr
Institute for Software Technology)
are working to address this challenge
as part of two ongoing research
projects. The developed solutions
consist of two main pillars: (1) monitoring
the adherence to data protection
requirements, which is developed
in the iObserve project, and (2)
adapting the cloud system to react to
– actual or imminent – requirements
violations, which is developed in the
RestAssured project.
In the iObserve project, funded
by the DFG, the focus is on monitoring
data security in a cloud system.
Through appropriate mechanisms,
the violation of security requirements
can be detected at runtime,
making it possible to avoid or mitigate
security breaches. In particular,
violations of geo-location policies
can be detected and appropriate
counter-measures may be taken.
In the RestAssured project,
funded by the European Union, the
focus is on adaptation by leveraging
innovative security mechanisms such
as hardware enclaves and homomorphic
encryption to guarantee security
in an adaptive and integrated
way. By also considering the impact
of the used security mechanisms on
other quality attributes like costs and
performance, security requirements
can be fulfilled in a globally optimal
way.

O presente estudo visou avaliar as abordagens clareadoras em substratos dentinários hígidos clareados com peróxido de hidrogênio 40% combinado com soluções corantes, café e açaí, influenciaria no resultado do clareamento. Realizou-se um ensaio laboratorial in vitro, cujas variáveis de resposta foram: pigmentação dos dentes durante o clareamento dental. Foram utilizados incisivos bovinos (n=84) distribuídos em 7 grupos, sendo cada um composto por 12 dentes, distribuídos de forma aleatória, de acordo com a frequência de contato e o tipo de solução de corante utilizada durante o clareamento dental. A cor foi medida com um espectrofotômetro digital e os dados foram expressos como estatísticas: média e desvio padrão. O contato com corantes durante o tratamento clareador de consultório com peróxido de carbamida a 40% não influenciou as médias de coloração após duas sessões de clareamento. Entretanto, a velocidade do efeito clareador teve influência entre a segunda sessão de clareamento e a segunda exposição aos corantes sendo significativamente maior diante da utilização de açaí após 2 horas de clareamento do que pelo café aplicado após 12 horas. O contato com corantes, durante o clareamento dental de consultório, não influenciou o resultado final do clareamento, embora tenha havido uma diminuição do efeito clareador entre a segunda sessão de clareamento e a segunda exposição ao corante. O contato com corantes durante o tratamento clareador de consultório com peróxido de carbamida a 40% não influenciou as médias de coloração após duas sessões de clareamento.
Density Functional Tight-Binding Captures Plasmon-Driven H$_2$ Dissociation on Al Nanocrystals

description: Aluminum nanocrystals offer a promising platform for plasmonic photocatalysis, yet a detailed understanding of their electron dynamics and consequent photocatalytic performance has been challenging thus far due to computational limitations. Here, we employ density functional tight-binding methods (DFTB) to investigate the optical properties and H2 dissociation dynamics of Al nanocrystals with varying sizes and geometries. Our real-time simulations reveal that Al's unique free-electron nature enables efficient light-matter interactions and rapid electronic thermalization. Cubic and octahedral nanocrystals ranging from 0.5 to 4.5 nm exhibit size-dependent plasmon resonances in the UV, with distinct spectral features arising from the particle geometry and electronic structure. By simulating H2 dissociation near Al nanocrystals, we demonstrate that hot electrons generated through plasmon excitation can overcome the molecule's strong chemical bond within tens of femtoseconds. The laser intensity threshold is comparable to previous reports for Ag nanocrystals, though significantly lower than that of Au. Notably, the dipolar plasmon mode demonstrates higher efficiency for this reaction than the localized interband transition for particles at these sizes. Taken together, this work provides mechanistic insights into plasmon-driven catalysis and showcases DFTB's capability to study quantum plasmonics at unprecedented length and time scales.
Molecular dynamics and stochastic processes for active fluids
Creators: name: Montana, Federica
Publisher: name: Swinburne
Year: 2024

description: This work investigates active fluids both with a stochastic thermodynamics approach and molecular dynamics point of view. The term 'active particles' describe self-propelling particles which consume energy in order to move. They range in size from micron molecules such as bacteria to living organisms, such as large mammals. The interest in the study of active particles has increased, mainly due to progress achieved in biomedical and technological applications, such as drug delivery. In this thesis, the dynamics and thermodynamics of active elliptical particles have been investigated by incorporating inertia and geometry effect in active Langevin dynamics. Finally, the methodology has been extended to nonequilibrium molecular dynamics simulations.

description: Three researchers at the University
of Duisburg-Essen opened a company
called Locoslab after several
years of research in the area of localization.
This article discusses the
experiences of the research team in
the design, development and reallife
testing of SIMON Mobile, a
mobile application that uses a cloud
infrastructure to provide support
for mobility impaired users for different
cities like Madrid, Parma,
Lisbon and Reading. The application
is the main product of three
years of collaborative research as
part of the SIMON European project,
that involves researchers from
Spain, Italy, Portugal and Germany.
The main asset of the application is
the seamless integration of indoor
and outdoor navigation routes and
the fact that the computed routes
take into account the characteristics
of the user in terms of capabilities
and preferences. At the time of this
writing, SIMON Mobile has been
available for several months at the
Google and Apple App Stores and
has been downloaded over 1000
times with very good user feedback.
Additionally, all of the operations
from the computation and retrieval
of the map tiles to the algorithm that
computes the optimal route for the
user, are performed in the cloud.
The client application simply acts as
the local device where the information
from the cloud is presented in
the appropriate form to the user.
This has the advantages that routing
algorithms, for example, can be
improved on the cloud backend and
do not require the update of the
application on the client side in
order to use the new and improved
services.

requirements. We propose to use
Process Mining to handle complexity

the risks. Process Mining facilitates
an enhanced understanding of

detailed analysis. Process Mining can
be used by auditors to assess the

Process Mining in the general form
of Event Mining for auditing cloud

description: In this Fisheries Centre Research Report (FCRR), Project Seahorse team members, with members of the IUCN SSC Seahorse, Pipefish and Seadragon Specialist Group (SPS SG, www.iucn-seahorse.org) investigated the international live trade in seahorses by species, countries of origin, whether specimens were wild sourced or cultured, destinations, volumes, and their changes over time. They did this by undertaking extensive stakeholder interviews, as well as reviewing government and industry datasets to compare seahorse trade across three geographies and four time periods – from pre-listing by The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), through to late in the CITES review process (2013-2020). In addition to the global overview, they also delved into two main destination markets for the live seahorse trade: the European Union (EU) and the United States of America (U.S.).

description: Sea level rise and reduction of groundwater fluxes due to changes in rainfall patterns are the two major climate change–induced hydrological variables that can severely affect saltwater intrusion in coastal aquifers. In this study we use a combination of laboratory experiments and numerical simulations to study the impacts of changes in one of these climate change–induced hydrological variables, groundwater flux, on saltwater intrusion process. We have completed experiments in a laboratory-scale model to study the changes in two types of groundwater fluxes—areal recharge flux and regional flux. The experimental results were modeled using the numerical code SEAWAT. The transient data sets reported in this study are useful benchmarks for testing numerical models that employ flux-type boundary conditions. Also, based on the experimental observations, we hypothesize that when the fluxes are perturbed, it would require relatively less time for a salt wedge to recede from an aquifer when compared to the time required to advance into the aquifer. This rather counterintuitive hypothesis implies that saltwater intrusion and receding processes are asymmetric and the timescales associated with these processes will be different. We use a combination of laboratory and numerical experiments to test this hypothesis and use the resulting data set to explain the reason for the difference in intrusion rates.

description: Modern high-tech steels offer many
possibilities for improvements in
engineering applications, while virtual
labs can help to taylor the materials
to be best suited for an underlying
application. A realistic modeling
of the inherent phenomena
acting on the microstructural level
are inevitable for reliable computations.
In the case of dual-phase steel,
the interaction of the two phases in
the microstructure together with the
polycrystalline structure of each
phase contribute to the complex
macroscopic material response.
Homogenization approaches are
necessary to account for the effects
on both scales, such as the FE2-
method. Due to the enormous size
of the simulations, the computational
power of modern supercomputers
is necessary. State-of-the-art
computer architectures provide up
to ten million parallel processing
units and to exploit them efficiently,
it is mandatory that the mayor part
of the underlying computations of a
numerical method can be performed
in parallel. This is possible in the
FE2-method as well as in domain
decomposition methods as FETI-DP (Finite Element Tearing and
Interconnecting – Dual-Primal). The
combination of both methods,
named FE2TI, managed to run efficiently
on some of the largest supercomputers.

description: Valence-bound (VB) and diffuse-bound (DB) anions of noble-gas (Ar, Kr, and Xe) complexes with uracil have been studied with ab initio methods. MP2 optimizations revealed minima corresponding to anions of both kinds in each case. Coupled-cluster singles and doubles with perturbative triples, CCSD(T), and electron propagator single-point calculations were performed in order to assess vertical and adiabatic electron detachment energies of these complexes. Ab initio electron propagator calculations employed the outer valence Green’s function and partial third-order approximations, and the algebraic diagrammatic construction in third order. Basis set effects have been systematically examined. DB anions of all three complexes were adiabatically bound, with calculated adiabatic electron attachment energies below 0.06 eV. Corresponding vertical electron detachment energies were below 0.1 eV. As to VB anions, only the Xe complex had a positive adiabatic electron detachment energy, of 0.01 eV, with a corresponding vertical electron detachment energy of 0.6 eV. These computational findings are consistent with the interpretation of results previously obtained experimentally
Subunit D of RNA Polymerase from Methanosarcina acetivorans Contains Two Oxygen-labile [4Fe-4S] Clusters IMPLICATIONS FOR OXIDANT-DEPENDENT REGULATION OF TRANSCRIPTION

description: Subunit D of multisubunit RNA polymerase from many species of archaea is predicted to bind one to two iron-sulfur (Fe-S) clusters, the function of which is unknown. A survey of encoded subunit D in the genomes of sequenced archaea revealed six distinct groups based on the number of complete or partial [4Fe-4S] cluster motifs within domain 3. Only subunit D from strictly anaerobic archaea, including all members of the Methanosarcinales, are predicted to bind two [4Fe-4S] clusters. We report herein the purification and characterization of Methanosarcina acetivorans subunit D in complex with subunit L. Expression of subunit D and subunit L in Escherichia coli resulted in the purification of a D-L heterodimer with only partial [4Fe-4S] cluster content. Reconstitution in vitro with iron and sulfide revealed that the M. acetivorans D-L heterodimer is capable of binding two redox-active [4Fe-4S] clusters. M. acetivorans subunit D deleted of domain 3 (D Delta D3) was still capable of co-purifying with subunit L but was devoid of [4Fe-4S] clusters. Affinity purification of subunit D or subunit D Delta D3 from M. acetivorans resulted in the co-purification of endogenous subunit L with each tagged subunit D. Overall, these results suggest that domain 3 of subunit D is required for [4Fe-4S] cluster binding, but the [4Fe-4S] clusters and domain 3 are not required for the formation of the D-L heterodimer. However, exposure of two [4Fe-4S] cluster-containing D-L heterodimer to oxygen resulted in loss of the [4Fe-4S] clusters and subsequent protein aggregation, indicating that the [4Fe-4S] clusters influence the stability of the D-L heterodimer and therefore have the potential to regulate the assembly and/or activity of RNA polymerase in an oxidant-dependent manner.

Interpretation of the photoelectron spectra of superalkali species: Na3O and Na3O-

Subjects: photoelectron spectra Na3O ab initio electron propagator calculation

description: Recently measured photoelectron spectra of the Na3O- anion have been interpreted with the aid of ab initio electron propagator calculations. As in the case of the Li3O-, we propose that the photoionization of ground and excited neutral states, in a sequential two photon absorption mechanism, plays a role in the interpretation of the observed spectrum. The lowest vertical electron detachment energy of Na3O- corresponds to a Dyson orbital that is composed chiefly of diffuse Na s functions and connects a D-3h singlet anion to an uncharged species with the same point group. Electron binding energies of isomers of the anion with different point groups or multiplicities have been considered. The relative magnitudes of the ionization energies of the neutral Li3O and Na3O species are also discussed. Whereas the most recent experimental data hold that Na3O has the higher ionization energy, this work asserts the opposite trend. (C) 2012 American Institute of Physics.

At the same time, by using cloud

On the accuracy of explicitly correlated coupled-cluster interaction energies - have orbital results been beaten yet?

description: The basis set convergence of weak interaction energies for dimers of noble gases helium through krypton is studied for six variants of the explicitly correlated, frozen geminal coupled-cluster singles, doubles, and noniterative triples [CCSD(T)-F12] approach: the CCSD(T)-F12a, CCSD(T)- F12b, and CCSD(T)(F12*) methods with scaled and unscaled triples. These dimers were chosen because CCSD(T) complete-basis-set (CBS) limit benchmarks are available for them to a particularly high precision. The dependence of interaction energies on the auxiliary basis sets has been investigated and it was found that the default resolution-of-identity sets cc-pVXZ/JKFIT are far from adequate in this case. Overall, employing the explicitly correlated approach clearly speeds up the basis set convergence of CCSD(T) interaction energies, however, quite surprisingly, the improvement is not as large as the one achieved by a simple addition of bond functions to the orbital basis set. Bond functions substantially improve the CCSD(T)-F12 interaction energies as well. For small and moderate bases with bond functions, the accuracy delivered by the CCSD(T)-F12 approach cannot be matched by conventional CCSD(T). However, the latter method in the largest available bases still delivers the CBS limit to a better precision than CCSD(T)-F12 in the largest bases available for that approach. Our calculations suggest that the primary reason for the limited accuracy of the large-basis CCSD(T)-F12 treatment are the approximations made at the CCSD-F12 level and the non-explicitly correlated treatment of triples. In contrast, the explicitly correlated second-order Møller-Plesset perturbation theory (MP2-F12) approach is able to pinpoint the complete-basis-set limit MP2 interaction energies of rare gas dimers to a better precision than conventional MP2. Finally, we report and analyze an unexpected failure of the CCSD(T)-F12 method to deliver the core-core and core-valence correlation corrections to interaction energies consistently and accurately. ©
