text: "Micro- and smart grids (MSG) play an important role both for integrating\r\nrenewable
energy sources in conventional electricity grids and for providing\r\npower supply
in remote areas. Modern MSGs are largely driven by power\r\nelectronic converters
due to their high efficiency and flexibility.\r\nNevertheless, controlling MSGs
is a challenging task due to highest\r\nrequirements on energy availability, safety
and voltage quality within a wide\r\nrange of different MSG topologies. This results
in a high demand for\r\ncomprehensive testing of new control concepts during their
development phase\r\nand comparisons with the state of the art in order to ensure
their feasibility.\r\nThis applies in particular to data-driven control approaches
from the field of\r\nreinforcement learning (RL), whose stability and operating
behavior can hardly\r\nbe evaluated a priori. Therefore, the OpenModelica Microgrid
Gym (OMG) package,\r\nan open-source software toolbox for the simulation and control
optimization of\r\nMSGs, is proposed. It is capable of modeling and simulating
arbitrary MSG\r\ntopologies and offers a Python-based interface for plug \\& play
controller\r\ntesting. In particular, the standardized OpenAI Gym interface allows
for easy\r\nRL-based controller integration. Besides the presentation of the OMG
toolbox,\r\napplication examples are highlighted including safe Bayesian optimization
for\r\nlow-level controller tuning."

text: Mobile shopping apps have been using Augmented Reality (AR) in the last years
to place their products in the environment of the customer. While this is possible
with atomic 3D objects, there is is still a lack in the runtime configuration of
3D object compositions based on user needs and environmental constraints. For
this, we previously developed an approach for model-based AR-assisted product
configuration based on the concept of Dynamic Software Product Lines. In this demonstration
paper, we present the corresponding tool support ProConAR in the form of a Product
Modeler and a Product Configurator. While the Product Modeler is an Angular web
app that splits products (e.g. table) up into atomic parts (e.g. tabletop, table
legs, funnier) and saves it within a configuration model, the Product Configurator
is an Android client that uses the configuration model to place different product
configurations within the environment of the customer. We show technical details
of our ready to use tool-chain ProConAR by describing its implementation and usage
as well as pointing out future research directions.

text: "Modern services consist of modular, interconnected\r\ncomponents, e.g., microservices
forming a service mesh. To\r\ndynamically adjust to ever-changing service demands,
service\r\ncomponents have to be instantiated on nodes across the network.\r\nIncoming
flows requesting a service then need to be routed\r\nthrough the deployed instances
while considering node and link\r\ncapacities. Ultimately, the goal is to maximize
the successfully\r\nserved flows and Quality of Service (QoS) through online service\r\ncoordination.
Current approaches for service coordination are\r\nusually centralized, assuming
up-to-date global knowledge and\r\nmaking global decisions for all nodes in the
network. Such global\r\nknowledge and centralized decisions are not realistic
in practical\r\nlarge-scale networks.\r\n\r\nTo solve this problem, we propose
two algorithms for fully\r\ndistributed service coordination. The proposed algorithms
can be\r\nexecuted individually at each node in parallel and require only\r\nvery
limited global knowledge. We compare and evaluate both\r\nalgorithms with a state-of-the-art
centralized approach in extensive\r\nsimulations on a large-scale, real-world
network topology.\r\nOur results indicate that the two algorithms can compete
with\r\ncentralized approaches in terms of solution quality but require\r\nless
global knowledge and are magnitudes faster (more than\r\n100x)."

text: "Modern services comprise interconnected components,\r\ne.g., microservices
in a service mesh, that can scale and\r\nrun on multiple nodes across the network
on demand. To process\r\nincoming traffic, service components have to be instantiated
and\r\ntraffic assigned to these instances, taking capacities and changing\r\ndemands
into account. This challenge is usually solved with\r\ncustom approaches designed
by experts. While this typically\r\nworks well for the considered scenario, the
models often rely\r\non unrealistic assumptions or on knowledge that is not available\r\nin
practice (e.g., a priori knowledge).\r\n\r\nWe propose a novel deep reinforcement
learning approach that\r\nlearns how to best coordinate services and is geared
towards\r\nrealistic assumptions. It interacts with the network and relies on\r\navailable,
possibly delayed monitoring information. Rather than\r\ndefining a complex model
or an algorithm how to achieve an\r\nobjective, our model-free approach adapts
to various objectives\r\nand traffic patterns. An agent is trained offline without
expert\r\nknowledge and then applied online with minimal overhead. Compared\r\nto
a state-of-the-art heuristic, it significantly improves flow\r\nthroughput and
overall network utility on real-world network\r\ntopologies and traffic traces.
It also learns to optimize different\r\nobjectives, generalizes to scenarios with
unseen, stochastic traffic\r\npatterns, and scales to large real-world networks."

text: "Ordinary differential equations (ODEs) and partial differential equations
(PDEs) arise\r\nin most scientific disciplines that make use of mathematical techniques.
As exact solutions are in general not computable, numerical methods are used to
obtain approximate\r\nsolutions. In order to draw valid conclusions from numerical
computations, it is crucial\r\nto understand which qualitative aspects numerical
solutions have in common with the\r\nexact solution. Symplecticity is a subtle
notion that is related to a rich family of geometric properties of Hamiltonian
systems. While the effects of preserving symplecticity\r\nunder discretisation
on long-term behaviour of motions is classically well known, in this\r\nthesis\r\n(a)
the role of symplecticity for the bifurcation behaviour of solutions to Hamiltonian\r\nboundary
value problems is explained. In parameter dependent systems at a bifurcation\r\npoint
the solution set to a boundary value problem changes qualitatively. Bifurcation\r\nproblems
are systematically translated into the framework of classical catastrophe theory.
It is proved that existing classification results in catastrophe theory apply
to\r\npersistent bifurcations of Hamiltonian boundary value problems. Further
results for\r\nsymmetric settings are derived.\r\n(b) It is proved that to preserve
generic bifurcations under discretisation it is necessary and sufficient to preserve
the symplectic structure of the problem.\r\n(c) The catastrophe theory framework
for Hamiltonian ODEs is extended to PDEs\r\nwith variational structure. Recognition
equations for A-series singularities for functionals on Banach spaces are derived
and used in a numerical example to locate high-codimensional bifurcations.\r\n(d)
The potential of symplectic integration for infinite-dimensional Lie-Poisson systems
(Burgers’ equation, KdV, fluid equations, . . . ) using Clebsch variables is analysed.\r\nIt
is shown that the advantages of symplectic integration can outweigh the disadvantages
of integrating over a larger phase space introduced by a Clebsch representation.\r\n(e)
Finally, the preservation of variational structure of symmetric solutions in multisymplectic
PDEs by multisymplectic integrators on the example of (phase-rotating)\r\ntravelling
waves in the nonlinear wave equation is discussed."

text: Current GNN architectures use a vertex neighborhood aggregation scheme, which
limits their discriminative power to that of the 1-dimensional Weisfeiler-Lehman
(WL) graph isomorphism test. Here, we propose a novel graph convolution operator
that is based on the 2-dimensional WL test. We formally show that the resulting
2-WL-GNN architecture is more discriminative than existing GNN approaches. This
theoretical result is complemented by experimental studies using synthetic and
real data. On multiple common graph classification benchmarks, we demonstrate
that the proposed model is competitive with state-of-the-art graph kernels and
GNNs.

text: "In many real-world applications, the relative depth of objects in an image
is\r\ncrucial for scene understanding, e.g., to calculate occlusions in augmented\r\nreality
scenes. Predicting depth in monocular images has recently been tackled\r\nusing
machine learning methods, mainly by treating the problem as a regression\r\ntask.
Yet, being interested in an order relation in the first place,\r\nranking methods
suggest themselves as a natural alternative to regression, and\r\nindeed, ranking
approaches leveraging pairwise comparisons as training\r\ninformation (\"object
A is closer to the camera than B\") have shown promising\r\nperformance on this
problem. In this paper, we elaborate on the use of\r\nso-called \\emph{listwise}
ranking as a generalization of the pairwise approach.\r\nListwise ranking goes
beyond pairwise comparisons between objects and considers\r\nrankings of arbitrary
length as training information. Our approach is based on\r\nthe Plackett-Luce
model, a probability distribution on rankings, which we\r\ncombine with a state-of-the-art
neural network architecture and a sampling\r\nstrategy to reduce training complexity.
An empirical evaluation on benchmark\r\ndata in a \"zero-shot\" setting demonstrates
the effectiveness of our proposal\r\ncompared to existing ranking and regression
methods."

text: The challenge of designing new tunable nonlinear dielectric materials with
tailored properties has attracted an increasing amount of interest recently. Herein,
we study the effective nonlinear dielectric response of a stochastic paraelectric-dielectric
composite consisting of equilibrium distributions of circular and partially penetrable
disks (or parallel, infinitely long, identical, partially penetrable, circular
cylinders) of a dielectric phase randomly dispersed in a continuous matrix of
a paraelectric phase. The random microstructures were generated using the Metropolis
Monte Carlo algorithm. The evaluation of the effective permittivity and tunability
were carried out by employing either a Landau thermodynamic model or its Johnson’s
approximation to describe the field-dependent permittivity of the paraelectric
phase and solving continuum-electrostatics equations using finite element calculations.
We reveal that the percolation threshold in this composite governs the critical
behavior of the effective permittivity and tunability. For microstructures below
the percolation threshold, our simulations demonstrate a strong nonlinear behaviour
of the field-dependent effective permittivity and very high tunability that increases
as a function of dielectric phase concentration. Above the percolation threshold,
the effective permittivity shows the tendency to linearization and the tunability
dramatically drops down. The highly reduced permittivity and extraordinarily high
tunability are obtained for the composites with dielectric impenetrable disks
at high concentrations, in which the triggering of the percolation transition
is avoided. The reported results cast light on distinct nonlinear behaviour of
2D and 3D stochastic composites and can guide the design of novel composites with
the controlled morphology and tailored permittivity and tunability.

text: Previous accounting research shows that taxes affect decision making by individuals
and firms. Most studies assume that agents have an accurate perception regarding
their tax burden. However, there is a growing body of literature analyzing whether
taxes are indeed perceived correctly. We review 127 studies on the measurement
of tax misperception and its behavioral implications. The review reveals that
many taxpayers have substantial tax misperceptions that lead to biased decision
making. We develop a Behavioral Taxpayer Response Model on the impact of provided
tax information on tax perception. Besides individual traits, characteristics
of the tax information and the decision environment determine the extent of tax
misperception. We discuss opportunities for future research and methodological
limitations. While there is much evidence on tax misperception at the individual
level, we hardly find any research at the firm level. Little is known about the
real effects of managers’ tax misperception and on how tax information is strategically
managed to impact stakeholders. This research gap is surprising as a large part
of the accounting literature analyzes decision making and disclosure of firms.
We recommend a mixed-method approach combining experiments, surveys, and archival
data analyses to improve the knowledge on tax misperception and its consequences.

text: We analyze the impact of trust on bargaining behavior between auditor and
auditee in a tax setting. We study the effect of interpersonal trust and trust
in government on both taxpayer and tax auditor. In an experiment with variation
in pairwise trust settings, we find evidence that both kinds of trust affect the
bargaining behavior, albeit in different ways. While trust in government increases
taxpayers’ tax offers, interpersonal trust may lead to more concessionary behavior
of tax auditors moderated by trust in government. Our findings help tax authorities
to shape programs to enhance compliance in an atmosphere of trust.

text: This study examines the visibility of the GAAP effective tax rate (ETR) in
firms’ financial statements as a distinct disclosure choice. Applying a game-theory
disclosure model for voluntary disclosure strategies of firms to a tax setting,
we argue that firms face a trade-off in their ETR disclosure decisions. On the
one hand, firms have an incentive to enhance their ETR disclosure when the ratio
offers shareholders “favourable conditions”, for example in terms of higher expected
after-tax cash-flows. On the other hand, the disclosure of a favourable low ETR
could attract the attention of tax auditors and the public and ultimately result
in disclosure costs. We empirically test disclosure behaviour by examining the
relation between disclosure visibility and different ETR conditions that reflect
different stakeholder specific costs and benefits. While we find that unfavourable
ETR conditions are not highlighted, we observe higher disclosure visibility for
favourable ETRs (smooth, close to the industry average, decreasing). Additional
analyses reveal that this high visibility is characteristic of firm-years with
only moderately decreasing ETRs at usual ETR levels, while extreme ETRs are not
highlighted. Interestingly and in contrast to our main results, a subsample of
family firms do not seem to highlight favourable ETRs.

text: This article comprehensively reviews Australia’s corporate income tax complexity
as faced by multinational corporations (MNCs) and compares it to the average of
the remaining OECD countries. Building on unique survey data, I find that the
Australian tax code is considerably more complex than the OECD average, which
is mainly due to overly complex anti-avoidance legislation, such as regulations
on transfer pricing, general anti-avoidance or controlled foreign corporations
(CFC). In contrast, Australia’s tax framework, which covers processes and features
such as tax law enactment or tax audits, is close to the OECD average. A more
granular analysis yields further interesting insights. For example, excessive
details in the tax code and the time between the announcement of a tax law change
and its enactment turn out to be serious issues in Australia relative to the remaining
OECD countries.

text: This paper introduces an index that comprehensively measures the complexity
of countries’ corporate income tax systems faced by multinational corporations.
It builds on surveys of highly experienced tax consultants of the largest international
tax services networks. The index, called the Tax Complexity Index (TCI), is composed
of a tax code subindex covering tax regulations and a tax framework subindex covering
tax processes and features. For a sample of 100 countries, we find that tax complexity
varies considerably across countries, and tax code and framework complexity also
vary within countries. Among others, tax complexity is strongly driven by the
complexity of transfer pricing regulations in the tax code and tax audits in the
tax framework. When analyzing the associations with other country characteristics,
we identify different patterns. For example, with regard to GDP, we find a positive
association with tax code complexity and a negative association with tax framework
complexity, suggesting that highly economically developed countries tend to have
more complex tax codes and less complex frameworks. Overall, our tax complexity
measures can serve as valuable proxies in future research and supportive tools
for a variety of firm decisions and national and international tax policy discussions.
