text: A stepwise angular spectrum method (SASM) for curved interfaces is presented
to calculate the wave propagation in planar lens-like integrated optical structures
based on photonic slab waveguides. The method is derived and illustrated for an
effective 2D setup first and then for 3D slab waveguide lenses. We employ slab
waveguides of different thicknesses connected by curved surfaces to realize a
lens-like structure. To simulate the wave propagation in 3D including reflection
and scattering losses, the stepwise angular spectrum method is combined with full
vectorial finite element computations for subproblems with lower complexity. Our
SASM results show excellent agreement with rigorous numerical simulations of the
full structures with a substantially lower computational effort and can be utilized
for the simulation-based design and optimization of complex and large scale setups.

text: Augmented Reality (AR) has recently found high attention in mobile shopping
apps such as in domains like furniture or decoration. Here, the developers of
the apps focus on the positioning of atomic 3D objects in the physical environment.
With this focus, they neglect the configuration of multi-faceted 3D object composition
according to the user needs and environmental constraints. To tackle these challenges,
we present a model-based approach to support AR-assisted product con-figuration
based on the concept of Dynamic Software Product Lines. Our approach splits products
(e.g. table) into parts (e.g. tabletop, ta-ble legs, funnier) with their 3D objects
and additional information (e.g. name, price). The possible products, which can
be configured out of these parts, are stored in a feature model. At runtime, this
feature model can be used to configure 3D object compositions out of the product
parts and adapt to user needs and environmental constraints. The benefits of this
approach are demonstrated by a case study of configuring modular kitchens with
the help of a prototypical mobile-based implementation.

text: 'AbstractThe C-type lectin receptor langerin
plays a vital role in the mammalian defense against invading pathogens. Its function
hinges on the affinity to its co-factor Ca2+ which in turn
is regulated by the pH. We studied the structural consequences of pro-tonating
the allosteric pH-sensor histidine H294 by molecular dynamics simulations (total
simulation time: about 120 μs) and Markov models. We discovered a mechanism in
which the signal that the pH has dropped is transferred to the Ca2+-binding
site without transferring the initial proton. Instead, protonation of H294 unlocks
a conformation in which a protonated lysine side-chain forms a hydrogen bond with
a Ca2+-coordinating aspartic acid. This destabilizes Ca2+
in the binding pocket, which we probed by steered molecular dynamics. After Ca2+-release,
the proton is likely transferred to the aspartic acid and stabilized by a dyad
with a nearby glutamic acid, triggering a conformational transition and thus preventing
Ca2+-rebinding.'

text: "In this work, we initiate the research about the Gathering problem for robots\r\nwith
limited viewing range in the three-dimensional Euclidean space. In the\r\nGathering
problem, a set of initially scattered robots is required to gather at\r\nthe same
position. The robots' capabilities are very restricted -- they do not\r\nagree
on any coordinate system or compass, have a limited viewing range, have\r\nno
memory of the past and cannot communicate. We study the problem in two\r\ndifferent
time models, in FSYNC (fully synchronized discrete rounds) and the\r\ncontinuous
time model. For FSYNC, we introduce the 3D-Go-To-The-Center-strategy\r\nand prove
a runtime of $\\Theta(n^2)$ that matches the currently best runtime\r\nbound for
the same model in the Euclidean plane [SPAA'11]. Our main result is\r\nthe generalization
of contracting strategies (continuous time) from\r\n[Algosensors'17] to three
dimensions. In contracting strategies, every robot\r\nthat is located on the global
convex hull of all robots' positions moves with\r\nfull speed towards the inside
of the convex hull. We prove a runtime bound of\r\n$O(\\Delta \\cdot n^{3/2})$
for any three-dimensional contracting strategy, where\r\n$\\Delta$ denotes the
diameter of the initial configuration. This comes up to a\r\nfactor of $\\sqrt{n}$
close to the lower bound of $\\Omega (\\Delta \\cdot n)$\r\nwhich is already true
in two dimensions. In general, it might be hard for\r\nrobots with limited viewing
range to decide whether they are located on the\r\nglobal convex hull and which
movement maintains the connectivity of the swarm,\r\nrendering the design of concrete
contracting strategies a challenging task. We\r\nprove that the continuous variant
of 3D-Go-To-The-Center is contracting and\r\nkeeps the swarm connected. Moreover,
we give a simple design criterion for\r\nthree-dimensional contracting strategies
that maintains the connectivity of the\r\nswarm and introduce an exemplary strategy
based on this criterion."

text: The scientific impact of research papers is multi-dimensional and can be determined
quantitatively by means of citation analysis and qualitatively by means of content
analysis. Accounting for the widely acknowledged limitations of pure citation
analysis, we adopt a knowledge-based perspective on scientific impact to develop
a methodology for content-based citation analysis which allows determining how
papers have enabled knowledge development in subsequent research (knowledge impact).
As knowledge development differs between research genres, we develop a new knowledgebased
citation analysis methodology for the genre of standalone literature reviews (LRs).
We apply the suggested methodology to the IS business value domain by manually
coding 22 LRs and 1,228 citing papers (CPs) and show that the results challenge
the assumption that citations indicate knowledge impact. We derive implications
for distinguishing knowledge impact from citation impact in the LR genre. Finally,
we develop recommendations for authors of LRs, scientific evaluation committees
and editorial boards of journals how to apply and benefit from the suggested methodology,
and we discuss its efficiency and automatization.

text: Data-parallel applications run on cluster of servers in a datacenter and their
communication triggers correlated resource demand on multiple links that can be
abstracted as coflow. They often desire predictable network performance, which
can be passed to network via coflow abstraction for application-aware network
scheduling. In this paper, we propose a heuristic and an optimization algorithm
for predictable network performance such that they guarantee coflows completion
within their deadlines. The algorithms also ensure high network utilization, i.e.,
it's work-conserving, and avoids starvation of coflows. We evaluate both algorithms
via trace-driven simulation and show that they admit 1.1x more coflows than the
Varys scheme while meeting their deadlines.

text: The three-dimensional (3D) crystal structures of the GAF3 domain of
cyanobacteriochrome Slr1393 (Synechocystis PCC6803)
carrying a phycocyanobilin chromophore could be solved in both 15-Z
dark-adapted state, Pr, λmax = 649 nm, and 15-E
photoproduct, Pg, λmax = 536 nm (resolution, 1.6 and 1.86
Å, respectively). The structural data allowed identifying the large spectral shift
of the Pr-to-Pg conversion as resulting from an out-of-plane rotation of the chromophore’s
peripheral rings and an outward movement of a short helix formed from a formerly
unstructured loop. In addition, a third structure (2.1-Å resolution) starting
from the photoproduct crystals allowed identification of elements that regulate
the absorption maxima. In this peculiar form, generated during X-ray exposition,
protein and chromophore conformation still resemble the photoproduct state, except
for the D-ring already in 15-Z configuration and tilted
out of plane akin the dark state. Due to its formation from the photoproduct,
it might be considered an early conformational change initiating the parental
state-recovering photocycle. The high quality and the distinct features of the
three forms allowed for applying quantum-chemical calculations in the framework
of multiscale modeling to rationalize the absorption maxima changes. A systematic
analysis of the PCB chromophore in the presence and absence of the protein environment
showed that the direct electrostatic effect is negligible on the spectral tuning.
However, the protein forces the outer pyrrole rings of the chromophore to deviate
from coplanarity, which is identified as the dominating factor for the color regulation.

text: In this paper, a full-bridge modular multilevel converter (MMC) and two half-bridge-based
MMCs are evaluated for high-current low-voltage e.g. 100 - 400V DC-applications
such as electrolysis, arc welding or datacenters with DC-power distribution. Usually,
modular multilevel converters are used in high-voltage DC-applications (HVDC)
in the multiple kV-range, but to meet the needs of a high-current demand at low
output voltage levels, the modular converter concept requires adaptations. In
the proposed concept, the MMC is used to step-down the three-phase medium-voltage
of 10kV, and provide up to 1 MW to the load. Therefore, each module is extended
by an LLC resonant converter to adapt to the specific electrolyzers DC-voltage
range of 142 - 220V and to provide galvanic isolation. The six-arm MMC converter
with half-bridge modules can be simplified and optimized by removing three arms,
and thus halving the number of modules. In addition, the module voltage ripple
and capacitor losses are decreased by 22% and 30% respectively. By rearranging
the components of the half-bridge MMC to build a MMC consisting of grid-side full-bridge
modules, the voltage ripple is further reduced by 78% and capacitor losses by
64%, while ensuring identical costs and volume for all MMCs. Finally, the LLC
resonant converter is designed for the most efficient full-bridge MMC. The LLC
can not operate at resonance with a fixed nominal module voltage of 770V because
the output voltage is varying between 142 - 220V. By decreasing the module voltage
down to 600V, additional points of operation can be operated in resonance, and
the remaining are closer to resonance. The option to decrease the module voltage
down to 600V, increases the number of required modules per arm from 12 to 15,
which requires to balance the losses of the LLCs and the grid-side stages.

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

text: "We consider a resource-aware variant of the classical multi-armed bandit\r\nproblem:
In each round, the learner selects an arm and determines a resource\r\nlimit.
It then observes a corresponding (random) reward, provided the (random)\r\namount
of consumed resources remains below the limit. Otherwise, the\r\nobservation is
censored, i.e., no reward is obtained. For this problem setting,\r\nwe introduce
a measure of regret, which incorporates the actual amount of\r\nallocated resources
of each learning round as well as the optimality of\r\nrealizable rewards. Thus,
to minimize regret, the learner needs to set a\r\nresource limit and choose an
arm in such a way that the chance to realize a\r\nhigh reward within the predefined
resource limit is high, while the resource\r\nlimit itself should be kept as low
as possible. We derive the theoretical lower\r\nbound on the cumulative regret
and propose a learning algorithm having a regret\r\nupper bound that matches the
lower bound. In a simulation study, we show that\r\nour learning algorithm outperforms
straightforward extensions of standard\r\nmulti-armed bandit algorithms."
