text: GaAs quantum dots (QDs) have recently emerged as state-of-the-art
semiconductor sources of polarization-entangled photon pairs, however, without
site-control capability. In this work, we present a systematic study of epitaxially
grown GaAs/AlxGa1-xAs site-controlled pyramidal QDs possessing unrivaled excitonic
uniformity in comparison to their InGaAs counterparts or GaAs QDs fabricated by
other techniques. We have experimentally and systematically investigated the binding
energy of biexcitons, highlighting the importance of the uniformity of all excitonic
lines, rather than concentrating solely on the uniformity of the neutral exciton
as a typical figure of merit, as it is normally done in the literature. We present
optical signatures of GaAs QDs within a range of ∼250 meV with a remarkable uniformity
within each individual sample, the ability to excite the biexciton state resonantly,
and a systematic study of the fine-structure splitting (FSS) values—features important
for polarization entangled photon emission. While, in general, we observe relatively
large FSS distribution and associated non-uniformities, we discuss several strategies
to suppress the average FSS values to <15 μeV.

text: "Finding a good query plan is key to the optimization of query runtime. This
holds in particular for cost-based federation\r\nengines, which make use of cardinality
estimations to achieve this goal. A number of studies compare SPARQL federation
engines across different performance metrics, including query runtime, result
set completeness and correctness, number of sources selected and number of requests
sent. Albeit informative, these metrics are generic and unable to quantify and
evaluate the accuracy of the cardinality estimators of cost-based federation engines.
To thoroughly evaluate cost-based federation engines, the effect of estimated
cardinality errors on the overall query runtime performance must be measured.
In this paper, we address this challenge by presenting novel evaluation metrics
targeted at a fine-grained benchmarking of cost-based federated SPARQL query engines.
We evaluate five cost-based federated SPARQL query engines using existing as well
as novel evaluation metrics by using LargeRDFBench queries. Our results provide
a detailed analysis of the experimental outcomes that reveal novel insights, useful
for the development of future cost-based federated SPARQL query processing engines."

text: 'AbstractThe predictive performance of a
machine learning model highly depends on the corresponding hyper-parameter setting.
Hence, hyper-parameter tuning is often indispensable. Normally such tuning requires
the dedicated machine learning model to be trained and evaluated on centralized
data to obtain a performance estimate. However, in a distributed machine learning
scenario, it is not always possible to collect all the data from all nodes due
to privacy concerns or storage limitations. Moreover, if data has to be transferred
through low bandwidth connections it reduces the time available for tuning. Model-Based
Optimization (MBO) is one state-of-the-art method for tuning hyper-parameters
but the application on distributed machine learning models or federated learning
lacks research. This work proposes a framework$$\textit{MODES}$$MODESthat
allows to deploy MBO on resource-constrained distributed embedded systems. Each
node trains an individual model based on its local data. The goal is to optimize
the combined prediction accuracy. The presented framework offers two optimization
modes: (1)$$\textit{MODES}$$MODES-B
considers the whole ensemble as a single black box and optimizes the hyper-parameters
of each individual model jointly, and (2)$$\textit{MODES}$$MODES-I
considers all models as clones of the same black box which allows it to efficiently
parallelize the optimization in a distributed setting. We evaluate$$\textit{MODES}$$MODESby
conducting experiments on the optimization for the hyper-parameters of a random
forest and a multi-layer perceptron. The experimental results demonstrate that,
with an improvement in terms of mean accuracy ($$\textit{MODES}$$MODES-B),
run-time efficiency ($$\textit{MODES}$$MODES-I),
and statistical stability for both modes,$$\textit{MODES}$$MODESoutperforms
the baseline, i.e., carry out tuning with MBO on each node individually with its
local sub-data set.'

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: Upcoming sensing applications (acoustic or video) will have high processing
requirements not satisfiable by a single node or need input from multiple sources
(e.g., speaker localization). Offloading these applications to cloud or mobile
edge is an option, but when running in a wireless senor network (WSN), it might
entail needlessly high data rate and latency. An alternative is to spread processing
inside the WSN, which is particularly attractive if the application comprises
individual components. This scenario is typical for applications like acoustic
signal processing. Mapping components to nodes can be formulated as wireless version
of the NP-hard Virtual Network Embedding (VNE) problem, for which various heuristics
exist. We propose a Reinforcement Learning (RL) framework, which relies on Q-Learning
and uses either Greedy Epsilon or Epsilon Decay for exploration. We compare both
exploration methods to the result of an optimization approach and show empirically
that the RL framework achieves good results in terms of network delay within few
number of steps.

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: "Abstract\r\n Background\r\n
\ While observational studies revealed an inverse association
between serum 25(OH)vitamin D (25(OH)D) and the risk of attention deficit/hyperactivity
disorder (ADHD), the causality of this relationship remains unclear.\r\n
\ \r\n Methods\r\n
\ We conducted a bidirectional two-sample Mendelian Randomization
(MR) study to examine whether 25(OH)D has an effect on the risk to develop ADHD
or vice versa. Information on single nucleotide polymorphisms (SNP) associated
with serum 25(OH)D was obtained from a genome-wide association study (GWAS) considering
phenotype data from 79,366 individuals of European ancestry. Data on risk for
ADHD were derived from a GWAS analysis with 20,183 individuals diagnosed with
ADHD and 35,191 controls. For our analysis, we considered effect sizes based on
the European participants (19,099 cases and 34,194 controls).\r\n \r\n
\ Results\r\n Single
SNP analyses showed a causal effect of vitamin D on ADHD risk for only one SNP
(rs12785878, p = 0.024). The overall MR estimates did
not reveal a causal effect of 25(OH)D on risk for ADHD. In the reverse analysis,
neither any single nor the multi-SNP MR analyses showed a causal effect of ADHD
on 25(OH)D.\r\n \r\n Conclusion\r\n
\ Results from this two-sample MR study did not confirm
a causal effect of 25(OH)D on ADHD or vice versa. Accordingly, our study does
not provide evidence that improving 25(OH)D via supplementation could reduce the
risk of developing ADHD.\r\n "

text: "Abstract\r\n Purpose\r\n
\ The influences of nutrition in childhood on puberty onset
could have sustained consequences for health and wellbeing later in life. The
aim of this study was to investigate the prospective association of diet quality
prior to puberty with the timing of puberty onset.\r\n \r\n
\ Methods\r\n We
considered data from 3983 SCCNG (Southwest China Childhood Nutrition and Growth)
study participants with dietary data, anthropometric measurement, and information
on potential confounders at their baseline assessment (mean age: 7.1 years for
girls and 7.3 years for boys; mean length of follow-up was 4.2 years). Cox proportional
hazard regression estimating hazard ratios (HRs) and 95% confidence intervals
(CIs) were used to examine the relationship between diet quality and puberty onset.
Dietary intake at baseline was assessed using a validated food frequency questionnaire.
Diet quality was determined using the Chinese Children Dietary Index (CCDI) which
measures adherence to current dietary recommendations (theoretical range: 0–160
points). Age at Tanner stage 2 for breast/genital development (B2/G2), menarche
or voice break (M/VB) were used as pubertal markers.\r\n\r\n \r\n
\ Results\r\n The
CCDI score ranged from 56.2 to 136.3 for girls and 46.1–131.5 for boys. Pubertal
markers consistently indicate that girls and boys with higher diet quality were
more likely to enter their puberty later than their counterparts with lower CCDI
scores (higher vs. lower CCDI tertiles: adjusted HR for age at B2: 0.85 (95% CI,
0.81–0.94), p for trend = 0.02; G2: 0.86 (95% CI,0.80–0.96),
p for trend = 0.02; M: 0.86 (95% CI,0.80–0.95), p
for trend = 0.02; VB: 0.86 (95% CI,0.79–0.98), p for
trend = 0.03), after adjustment for paternal education level, baseline energy
intake, and pre-pubertal body fat.\r\n \r\n
\ Conclusions\r\n Our
data suggested a later puberty onset and later timing of progressed puberty stages
in children with a high diet quality, which were independent of pre-pubertal body
fat.\r\n "
