text: We investigate homogeneous coupled cell systems with high-dimensional internal
dynamics. In many studies on network dynamics, the analysis is restricted to networks
with one-dimensional internal dynamics. Here, we show how symmetry explains the
relation between dynamical behavior of systems with one-dimensional internal dynamics
and with higher dimensional internal dynamics, when the underlying network topology
is the same. Fundamental networks of homogeneous coupled cell systems (B. Rink,
J. Sanders. Coupled Cell Networks and Their Hidden Symmetries. SIAM J. Math. Anal.
46.2 (2014)) can be expressed in terms of monoid representations, which uniquely
decompose into indecomposable subrepresentations. In the high-dimensional internal
dynamics case, these subrepresentations are isomorphic to multiple copies of those
one computes in the one-dimensional internal dynamics case. This has interesting
implications for possible center subspaces in bifurcation analysis. We describe
the effect on steady state and Hopf bifurcations in l-parameter families of network
vector fields. The main results in that regard are that (1) generic one-parameter
steady state bifurcations are qualitatively independent of the dimension of the
internal dynamics and that, (2) in order to observe all generic l-parameter bifurcations
that may occur for internal dynamics of any dimension, the internal dynamics has
to be at least l-dimensional for steady state bifurcations and 2l-dimensional
for Hopf bifurcations. Furthermore, we illustrate how additional structure in
the network can be exploited to obtain even greater understanding of bifurcation
scenarios in the high-dimensional case beyond qualitative statements about the
collective dynamics. One-parameter steady state bifurcations in feedforward networks
exhibit an unusual amplification in the asymptotic growth rates of individual
cells, when these are one-dimensional (S. von der Gracht, E. Nijholt, B. Rink.
Amplified steady state bifurcations in feedforward networks. Nonlinearity 35.4
(2022)). As another main result, we prove that (3) the same cells exhibit this
amplifying effect with the same growth rates when the internal dynamics is high-dimensional.

text: In this article, we investigate symmetry properties of distributed systems
of mobile robots. We consider a swarm of n robots in the OBLOT model and analyze
their collective Fsync dynamics using of equivariant dynamical systems theory.
To this end, we show that the corresponding evolution function commutes with rotational
and reflective transformations of R^2. These form a group that is isomorphic to
O(2) x S_n, the product group of the orthogonal group and the permutation on n
elements. The theory of equivariant dynamical systems is used to deduce a hierarchy
along which symmetries of a robot swarm can potentially increase following an
arbitrary protocol. By decoupling the Look phase from the Compute and Move phases
in the mathematical description of an LCM cycle, this hierarchy can be characterized
in terms of automorphisms of connectivity graphs. In particular, we find all possible
types of symmetry increase, if the decoupled Compute and Move phase is invertible.
Finally, we apply our results to protocols which induce state-dependent linear
dynamics, where the reduced system consisting of only the Compute and Move phase
is linear.

text: In this paper we introduce, in a Hilbert space setting, a second order dynamical
system with asymptotically vanishing damping and vanishing Tikhonov regularization
that approaches a multiobjective optimization problem with convex and differentiable
components of the objective function. Trajectory solutions are shown to exist
in finite dimensions. We prove fast convergence of the function values, quantified
in terms of a merit function. Based on the regime considered, we establish both
weak and, in some cases, strong convergence of trajectory solutions toward a weak
Pareto optimal solution. To achieve this, we apply Tikhonov regularization individually
to each component of the objective function. This work extends results from single
objective convex optimization into the multiobjective setting.

text: 'We present a new gradient-like dynamical system related to unconstrained
convex smooth multiobjective optimization which involves inertial effects and
asymptotic vanishing damping. To the best of our knowledge, this system is the
first inertial gradient-like system for multiobjective optimization problems including
asymptotic vanishing damping, expanding the ideas previously laid out in [H. Attouch
and G. Garrigos, Multiobjective Optimization: An Inertial Dynamical Approach to
Pareto Optima, preprint, arXiv:1506.02823, 2015]. We prove existence of solutions
to this system in finite dimensions and further prove that its bounded solutions
converge weakly to weakly Pareto optimal points. In addition, we obtain a convergence
rate of order \(\mathcal{O}(t^{-2})\) for the function values measured with a
merit function. This approach presents a good basis for the development of fast
gradient methods for multiobjective optimization.'

text: To model dynamical systems on networks with higher-order (non-pairwise) interactions,
we recently introduced a new class of ordinary differential equations (ODEs) on
hypernetworks. Here, we consider one-parameter synchrony breaking bifurcations
in such ODEs. We call a synchrony breaking steady-state branch ‘reluctant’ if
it is tangent to a synchrony space, but does not lie inside it. We prove that
reluctant synchrony breaking is ubiquitous in hypernetwork systems, by constructing
a large class of examples that support it. We also give an explicit formula for
the order of tangency to the synchrony space of a reluctant steady-state branch.

text: Tire and road wear are a major source of emissions of nonexhaust particulate
matter (PM) and make up the largest share of microplastics in the environment.
To reduce tire wear through numerical optimization of a vehicle's suspension system,
fast simulations of the representative usage of a vehicle are needed. Therefore,
this contribution evaluates if instead of a full simulation of a representative
test drive, only specific driving maneuvers resulting from a clustering of the
driving data can be used to predict tire wear. As a measure for tire wear, the
friction work between tire and road is calculated. It is shown that enough clusters
result in negligible deviations between the total friction work of the full simulation
and the cluster simulations as well as between the distributions of the friction
work over the tire width. The calculation time can be reduced to about 1% of the
full simulation.

text: The conduction of structure-borne sound through joints causes energy dissipation.
The sound reduction index describes this energy loss as a level decrease in the
particle velocity across series-connected damping elements for which the superposition
principle applies. This simple model can help to develop a testing method for
joints based on this characteristic energy loss. In this paper, this model is
experimentally evaluated for multiple in-series clinched aluminium sheets. Samples
connected by several clinch points arranged in parallel are investigated experimentally,
and the results are discussed.

text: In this work, the behavior of four different commercially available polarizing
agents is investigated employing the non-ionic model surfactant 1-octanol as analyte.
A relative method for the comparison of the proportion of the direct and indirect
polarization transfer pathways is established, allowing a direct comparison of
the polarization efficacy for different radicals and different parts of the 1-octanol
molecule despite differences in radical concentration or sample amount. With this
approach, it could be demonstrated that the hydrophilicity is a key factor in
the way polarization is transferred from the polarizing agent to the analyte.
These findings are confirmed by the determination of buildup times Tb, illustrating
that the choice of polarizing agent plays an essential role in ensuring an optimal
polarization transfer and therefore the maximum amount of enhancement possible
for DNP enhanced NMR measurements.

text: Of the many outstanding female philosophers of the European Enlightenment,
Emilie Du Châtelet excelled as a physicist, a philosopher, and a mathematician,
as well as a Bible critic. She was famous in her lifetime and was not completely
forgotten thereafter. Among her admirers, correspondents and friends were the
most acknowledged scholars of her time, including Voltaire, Clairault, Maupertuis,
Diderot, Helvetius, La Mettrie, Buffon, Christian Wolff, Leonard Euler, and Johann
II Bernoulli. Her philosophical work enjoyed high reputation and her opus magnum,
the Institutions physiques, was translated into Italian and German and proved
her to be an intellectual of European stature. Its defense of living forces and
its implied forecast into dynamics as well as her methodological grounding of
scientific knowledge as hypothetical, impacted philosophy and science. Reality
must by nature escape us. What we perceive are phenomena. Du Châtelet explains
the function of space and time to trace us back to the origin of phenomena. Her
influence on Kant is evident. Next to her writings in physics, mathematics, philosophy,
language, and logic, she contributed to morality and ethics. Du Châtelet left
an opus of quite systematic breadth. This impressive publishing activity excels
in the amount of its scientific and philosophical production to which a vast collection
of manuscripts must be added.She argued against prejudice and idolatry in philosophy
and science. Science is a cooperative undertaking over history and beyond nations.
Her moral writings align with ideas of the French materialists. Du Châtelet translated
and commented on Newton’s Principia, preparing thus the fertile soil of the generation
of physicists to come in France.

text: Transient changes of the optical response of WS2 monolayers are studied by
femtosecond broadband pump–probe spectroscopy. Time-dependent absorption spectra
are analyzed by tracking the line width broadening, bleaching, and energy shift
of the main exciton resonance as a function of time delay after the excitation.
Two main sources for the pump-induced changes of the optical response are identified.
Specifically, we find an interplay between modifications induced by many-body
interactions from photoexcited carriers and by the subsequent transfer of the
excitation to the phonon system followed by cooling of the material through the
heat transfer to the substrate.

text: The accuracy of water models derived from ab initio molecular dynamics simulations
by means on an improved force-matching scheme is assessed for various thermodynamic,
transport, and structural properties. It is found that although the resulting
force-matched water models are typically less accurate than fully empirical force
fields in predicting thermodynamic properties, they are nevertheless much more
accurate than generally appreciated in reproducing the structure of liquid water
and in fact superseding most of the commonly used empirical water models. This
development demonstrates the feasibility to routinely parametrize computationally
efficient yet predictive potential energy functions based on accurate ab initio
molecular dynamics simulations for a large variety of different systems. © 2016

text: An attended stimulus reduces the perceptual latency of a later stimulus at
the same location, leading to the intriguing finding that the perceived order
between the two is often reversed. This prior-entry effect has been well established
in a number of different cueing paradigms, mostly involving spatial attentional
shifts. Here we assess the time-course of prior entry when all stimuli appear
in rapid serial presentation at one location. Our findings indicate that the size
of the attentional enhancement is strongly affected by the stimulus onset asynchrony
between cue and target, with a rapid early peak, followed by decay. When task-irrelevant
cues are used, the cueing effect on prior entry is short-lived and peaks as early
as 50 ms. The benefit extends to about 100 ms when task-relevant cues are employed.
These results fit with a straightforward computational model of transient attentional
enhancement, peaking about 80 100 ms after stimulus detection. (PsycINFO Database

text: In this paper a switching linear dynamical model (SLDM) approach for speech
feature enhancement is improved by employing more accurate models for the dynamics
of speech and noise. The model of the clean speech feature trajectory is improved
by augmenting the state vector to capture information derived from the delta features.
Further a hidden noise state variable is introduced to obtain a more elaborated
model for the noise dynamics. Approximate Bayesian inference in the SLDM is carried
out by a bank of extended Kalman filters, whose outputs are combined according
to the a posteriori probability of the individual state models. Experimental results
on the AURORA2 database show improved recognition accuracy.

text: The Unified Modeling Language (UML) has received wide acceptance as a standard
language in the field of software specification by means of different diagram
types. In a recent version of UML, the textual Object Constraint Language (OCL)
was introduced to support specification of constraints for UML models. But OCL
currently does not provide sufficient means to specify constraints over the dynamic
behavior of a model. This article presents an OCL extension that is consistent
with current OCL and enables modelers to specify state-related time-bounded constraints.
We consider the case study of a flexible manufacturing system and identify typical
real-time constraints. The constraints are presented in our temporal OCL extension
as well as in temporal logic formulae. For general application, we define a semantics
of our OCL extension by means of a time-bounded temporal logic based on Computational
Tree Logic (CTL).
