text: "Model predictive control is a prominent approach to construct a feedback\r\ncontrol
loop for dynamical systems. Due to real-time constraints, the major\r\nchallenge
in MPC is to solve model-based optimal control problems in a very\r\nshort amount
of time. For linear-quadratic problems, Bemporad et al. have\r\nproposed an explicit
formulation where the underlying optimization problems are\r\nsolved a priori
in an offline phase. In this article, we present an extension\r\nof this concept
in two significant ways. We consider nonlinear problems and -\r\nmore importantly
- problems with multiple conflicting objective functions. In\r\nthe offline phase,
we build a library of Pareto optimal solutions from which we\r\nthen obtain a
valid compromise solution in the online phase according to a\r\ndecision maker's
preference. Since the standard multi-parametric programming\r\napproach is no
longer valid in this situation, we instead use interpolation\r\nbetween different
entries of the library. To reduce the number of problems that\r\nhave to be solved
in the offline phase, we exploit symmetries in the dynamical\r\nsystem and the
corresponding multiobjective optimal control problem. The\r\nresults are verified
using two different examples from autonomous driving."

text: There is a distinct increase in the prevalence of depression with
the onset of puberty. The role of peripubertal testosterone levels in boys in
this context is insufficiently understood and may be modulated by a functional
polymorphism of the androgen receptor gene (AR), a variable number of CAG repeats.
Moreover, there is preliminary evidence that the relationship between testosterone,
CAG repeat length, and the severity of depressive symptoms may differ between
subclinical and overt depression, but this has neither been studied in a clinical
sample of adolescents with depression nor compared between subclinical and overt
depression in an adequately powered study. To investigate the relationship between
free testosterone, CAG repeat length of the AR, depression status (subclinical
vs. overt), and the severity of depressive symptoms, 118 boys treated as in- or
daycare patients at a single psychiatric hospital were studied. Of these, 73 boys
had at least mild depressive symptoms according to the Beck Depression Inventory-II
(BDI-II > 13). Higher-order moderation analysis in the multiple regression
framework revealed a constant relationship between free testosterone and depression
severity irrespective of the number of CAG repeats in adolescents with a BDI-II
score ≤ 13. In adolescents with a BDI-II score > 13, however, there was
a significant negative relationship between free testosterone and BDI-II score
in patients with <19 CAG repeats and a significant positive relationship
regarding free testosterone and BDI-II score in those with more than 28 CAG repeats,
even when considering important covariates. These results suggest that the effects
of testosterone on mood in male adolescents with depression depend on the genetic
make-up of the AR as well as on depression status. This complex relationship should
be considered by future studies addressing mental health issues against an endocrine
background and may, moreover, contribute to tailored treatment concepts in psychiatric
medicine, especially in adults.

text: '(1) Background: Evidence has accumulated that patients with anorexia
nervosa (AN) are at higher risk for vitamin D deficiency than healthy controls.
In epidemiologic studies, low 25(OH) vitamin D (25(OH)D) levels were associated
with depression. This study analyzed the relationship between 25(OH)D serum levels
in adolescent patients and AN and depressive symptoms over the course of treatment.
(2) Methods: 25(OH)D levels and depressive symptoms were analyzed in 93 adolescent
(in-)patients with AN from the Anorexia Nervosa Day patient versus Inpatient (ANDI)
multicenter trial at clinic admission, discharge, and 1 year follow up. Mixed
regression models were used to analyze the relationship between 25(OH)D levels
and depressive symptoms assessed by the Beck Depression Inventory (BDI-II). (3)
Results: Although mean 25(OH)D levels constantly remained in recommended ranges
(≥50 nmol/L) during AN treatment, levels decreased from (in)patient admission
to 1 year follow up. Levels of 25(OH)D were neither cross-sectionally, prospectively,
nor longitudinally associated with the BDI-II score. (4) Conclusions: This study
did not confirm that 25(OH)D levels are associated with depressive symptoms in
patients with AN. However, increasing risks of vitamin D deficiency over the course
of AN treatment indicate that clinicians should monitor 25(OH)D levels.'

text: AbstractAnorexia nervosa (AN) is a severe
eating disorder and often associated with altered humoral immune responses. However,
distinct B cell maturation stages in peripheral blood in adolescents with AN have
not been characterized. Treatment effects and the relationship between clinical
and B cell parameters are also not fully understood. Here we investigated the
phenotype of circulating B cell subsets and the relationship with body composition
in adolescents with AN before (T0, n = 24) and after 6 weeks (T1, n = 20) of treatment.
Using multi-parameter flow cytometry, we found increased percentages of antigen-experienced
B cells and plasmablasts in patients with AN compared to healthy controls (n = 20).
In contrast, percentages of CD1d+CD5+
B cells and transitional B cells with immunoregulatory roles were reduced at T0
and T1. These B cell frequencies correlated positively with fat mass, fat mass
index (FMI), free fat mass index, and body mass index standard deviation score.
In addition, scavenger-like receptor CD5 expression levels were downregulated
on transitional B cells and correlated with fat mass and FMI in AN. Our findings
that regulatory B cell subgroups were reduced in AN and their strong relationship
with body composition parameters point toward an impact of immunoregulatory B
cells in the pathogenesis of AN.

text: 'When joining lightweight parts of various materials, clinching is a cost
efficient solution. In a production line, the quality of a clinch point is primarily
controlled by measurement of dimensions, which are accessible from outside. However,
methods such as visual testing and measuring the bottom thickness as well as the
outer diameter are not able to deliver any information about the most significant
geometrical characteristic of the clinch point, neck thickness and undercut. Furthermore,
ex-situ destructive methods such as microsectioning cannot detect elastic deformations
and cracks that close after unloading. In order to exceed the current limits,
a new non-destructive in-situ testing method for the clinching process is necessary.
This work proposes a concept to characterize clinch points in-situ by combining
two complementary non-destructive methods, namely, computed tomography (CT) and
ultrasonic testing. Firstly, clinch points with different geometrical characteristics
are analysed experimentally using ex-situ CT to get a highly spatially resolved
3D-image of the object. In this context, highly X-ray attenuating materials enhancing
the visibility of the sheet-sheet interface are investigated. Secondly, the test
specimens are modelled using finite element method (FEM) and a transient dynamic
analysis (TDA) is conducted to study the effect of the geometrical differences
on the deformation energy and to qualify the TDA as a fast in-situ non-destructive
method for characterizing clinch points at high temporal resolution. '

text: "Abstract\r\n Purpose\r\n
\ Studies about effects of lunch dietary Glycemic Index
(GI) on cognition of schoolchildren are scarce. Our previous CogniDo GI study
found no changes of cognition in the early postprandial phase after consumption
of two rice types with medium vs. high dietary GI for lunch (i.e., 45 min after
starting lunch). This study investigated whether the dietary GI of lunch has an
impact on cognition of schoolchildren in the late postprandial phase, 90 min after
lunch.\r\n \r\n Methods\r\n
\ A randomized, 2 × 2 crossover intervention study was conducted
at a comprehensive school with 5th and 6th grade students. Participants (n = 212)
were randomly assigned to either sequence 1 or 2. In the first period, participants
of sequence 1 received a dish with high GI rice (GI: 79), those of sequence 2
with medium GI rice (GI: 64)—in the second period, 1 week later, vice versa. Computer-based
cognitive testing was performed 90 min after lunch examining tonic alertness,
visual search and task switching, and working memory. Treatment effects and treatment
effects adjusted for estimated lunch glycemic load (GL) were analyzed using a
linear mixed model.\r\n \r\n Results\r\n
\ The selected cognitive parameters were not affected by
the GI of lunch 90 min after lunch, neither after intention-to-treat nor in the
per-protocol analysis. Adjustment for GL also did not change results.\r\n
\ \r\n Conclusion\r\n
\ The present study revealed no notable differences after
the consumption of two rice types with medium vs. high dietary GI for lunch in
children’s cognitive function in the late postprandial phase, 90 min after lunch.\r\n

text: 'Multi-objective (MO) optimization, i.e., the simultaneous optimization of
multiple conflicting objectives, is gaining more and more attention in various
research areas, such as evolutionary computation, machine learning (e.g., (hyper-)parameter
optimization), or logistics (e.g., vehicle routing). Many works in this domain
mention the structural problem property of multimodality as a challenge from two
classical perspectives: (1) finding all globally optimal solution sets, and (2)
avoiding to get trapped in local optima. Interestingly, these streams seem to
transfer many traditional concepts of single-objective (SO) optimization into
claims, assumptions, or even terminology regarding the MO domain, but mostly neglect
the understanding of the structural properties as well as the algorithmic search
behavior on a problem’s landscape. However, some recent works counteract this
trend, by investigating the fundamentals and characteristics of MO problems using
new visualization techniques and gaining surprising insights. Using these visual
insights, this work proposes a step towards a unified terminology to capture multimodality
and locality in a broader way than it is usually done. This enables us to investigate
current research activities in multimodal continuous MO optimization and to highlight
new implications and promising research directions for the design of benchmark
suites, the discovery of MO landscape features, the development of new MO (or
even SO) optimization algorithms, and performance indicators. For all these topics,
we provide a review of ideas and methods but also an outlook on future challenges,
research potential and perspectives that result from recent developments.'

text: "In this work we examine the inner mechanisms of the recently developed sophisticated
local search procedure SOMOGSA. This method solves multimodal single-objective
continuous optimization problems by first expanding the problem with an additional
objective (e.g., a sphere function) to the bi-objective space, and subsequently
exploiting local structures and ridges of the resulting landscapes. Our study
particularly focusses on the sensitivity of this multiobjectivization approach
w.r.t. (i) the parametrization of the artificial second objective, as well as
(ii) the position of the initial starting points in the search space.\r\n\r\nAs
SOMOGSA is a modular framework for encapsulating local search, we integrate Gradient
and Nelder-Mead local search (as optimizers in the respective module) and compare
the performance of the resulting hybrid local search to their original single-objective
counterparts. We show that the SOMOGSA framework can significantly boost local
search by multiobjectivization. Combined with more sophisticated local search
and metaheuristics this may help in solving highly multimodal optimization problems
in future."

text: We propose a reachability approach for infinite and finite horizon multi-objective
optimization problems for low-thrust spacecraft trajectory design. The main advantage
of the proposed method is that the Pareto front can be efficiently constructed
from the zero level set of the solution to a Hamilton-Jacobi-Bellman equation.
We demonstrate the proposed method by applying it to a low-thrust spacecraft trajectory
design problem. By deriving the analytic expression for the Hamiltonian and the
optimal control policy, we are able to efficiently compute the backward reachable
set and reconstruct the optimal trajectories. Furthermore, we show that any reconstructed
trajectory will be guaranteed to be weakly Pareto optimal. The proposed method
can be used as a benchmark for future research of applying reachability analysis
to low-thrust spacecraft trajectory design.

text: Orange-colored crystals of the oxoferrate tellurate K12+6xFe6Te4−xO27 [x=0.222(4)]
were synthesized in a potassium hydroxide hydroflux with a molar water–base ratio
n(H2O)/n(KOH) of 1.5 starting from Fe(NO3)3 ⋅ 9H2O, TeO2 and H2O2 at about 200 °C.
By using (NH4)2TeO4 instead of TeO2, a fine powder consisting of microcrystalline
spheres of K12+6xFe6Te4−xO27 was obtained. K12+6xFe6Te4−xO27 crystallizes in the
acentric cubic space group Iurn:x-wiley:09476539:media:chem202102464:chem202102464-math-0001
3d. [FeIIIO5] pyramids share their apical atoms in [Fe2O9] groups and two of their
edges with [TeVIO6] octahedra to form an open framework that consists of two loosely
connected, but not interpenetrating, chiral networks. The flexibility of the hinged
oxometalate network manifests in a piezoelectric response similar to that of LiNbO3.The
potassium cations are mobile in channels that run along the <111> directions and
cross in cavities acting as nodes. The ion conductivity of cold-pressed pellets
of ball-milled K12+6xFe6Te4−xO27 is 2.3×10^(−4) S ⋅ cm^(−1) at room temperature.
Magnetization measurements and neutron diffraction indicate antiferromagnetic
coupling in the [Fe2O9] groups.

text: In practise, it is often desirable to provide the decision-maker with a rich
set of diverse solutions of decent quality instead of just a single solution.
In this paper we study evolutionary diversity optimization for the knapsack problem
(KP). Our goal is to evolve a population of solutions that all have a profit of
at least (1 - {$ϵ$}) {$\cdot$} OPT, where OPT is the value of an optimal solution.
Furthermore, they should differ in structure with respect to an entropy-based
diversity measure. To this end we propose a simple ({$\mu$} + 1)-EA with initial
approximate solutions calculated by a well-known FPTAS for the KP. We investigate
the effect of different standard mutation operators and introduce biased mutation
and crossover which puts strong probability on flipping bits of low and/or high
frequency within the population. An experimental study on different instances
and settings shows that the proposed mutation operators in most cases perform
slightly inferior in the long term, but show strong benefits if the number of
function evaluations is severely limited.

text: Computing sets of high quality solutions has gained increasing interest in
recent years. In this paper, we investigate how to obtain sets of optimal solutions
for the classical knapsack problem. We present an algorithm to count exactly the
number of optima to a zero-one knapsack problem instance. In addition, we show
how to efficiently sample uniformly at random from the set of all global optima.
In our experimental study, we investigate how the number of optima develops for
classical random benchmark instances dependent on their generator parameters.
We find that the number of global optima can increase exponentially for practically
relevant classes of instances with correlated weights and profits which poses
a justification for the considered exact counting problem.

text: In the area of evolutionary computation the calculation of diverse sets of
high-quality solutions to a given optimization problem has gained momentum in
recent years under the term evolutionary diversity optimization. Theoretical insights
into the working principles of baseline evolutionary algorithms for diversity
optimization are still rare. In this paper we study the well-known Minimum Spanning
Tree problem (MST) in the context of diversity optimization where population diversity
is measured by the sum of pairwise edge overlaps. Theoretical results provide
insights into the fitness landscape of the MST diversity optimization problem
pointing out that even for a population of {$\mu$} = 2 fitness plateaus (of constant
length) can be reached, but nevertheless diverse sets can be calculated in polynomial
time. We supplement our theoretical results with a series of experiments for the
unconstrained and constraint case where all solutions need to fulfill a minimal
quality threshold. Our results show that a simple ({$\mu$} + 1)-EA can effectively
compute a diversified population of spanning trees of high quality.
