text: 'In order to reduce the fuel consumption and consequently the greenhouse emissions,
the automotive industry is implementing lightweight constructions in the body
in white production. As a result, the use of aluminum alloys is continuously increasing.
Due to poor weldability of aluminum in combination with other materials, mechanical
joining technologies like clinching are increasingly used. In order to predict
relevant characteristics of clinched joints and to ensure the reliability of the
process, it is simulated numerically during product development processes. In
this regard the predictive accuracy of the simulated process highly depends on
the implemented friction model. In particular, the frictional behavior between
the sheet metals affects the geometrical formation of the clinched joint significantly.
This paper presents a testing method, which enables to determine the frictional
coefficients between sheet metal materials for the simulation of clinching processes.
For this purpose, the correlation of interface pressure and the relative velocity
between aluminum sheets in clinching processes is investigated using numerical
simulation. Furthermore, the developed testing method focuses on the specimen
geometry as well as the reproduction of the occurring friction conditions between
two sheet metal materials in clinching processes. Based on a methodical approach
the test setup is explained and the functionality of the method is proven by experimental
tests using sheet metal material EN AW6014. '

text: To analyze the influence of suspension kinematics on tire wear, detailed
simulation models are required. In this study, a non-linear, flexible multibody
model of a rear axle system is built up in the simulation software MSC Adams/View.
The physical model comprises the suspension kinematics, compliance, and dynamics
as well as the non-linear behavior of the tire using the FTire model. FTire is
chosen because it has a separate tire tread model to compute the contact pressure
and friction force distribution in the tire contact patch. To build up the simulation
model, a large amount of data is needed. Bushings, spring, and damper characteristics
are modeled based on measurements. For the structural components (e.g., control
arms), reverse engineering techniques are used. The components are 3D-scanned,
reworked, and included as a modal reduced finite element (FE)-model using component
mode synthesis by Craig–Bampton. Finally, the suspension model is validated by
comparing the simulated kinematic and compliance characteristics to experimental
results. To investigate the interaction of suspension kinematics and tire wear,
straight line driving events, such as acceleration, driving with constant velocity,
and deceleration, are simulated with different setups of wheel suspension kinematics.
The influence of the setups on the resulting friction work between tire and road
is examined, and an exemplarily calculation of tire wear based on a validated
FTire tire model is carried out. The results demonstrate, on the one hand, that
the chosen concept of elasto-kinematic axle leads to a relatively good match with
experimental results and, on the other hand, that there are significant possibilities
to reduce tire wear by adjusting the suspension kinematics.

text: "Abstract\r\n Abductive reasoning
is a non-monotonic formalism stemming from the work of Peirce. It describes the
process of deriving the most plausible explanations of known facts. Considering
the positive version, asking for sets of variables as explanations, we study,
besides the problem of wether there exists a set of explanations, two explanation
size limited variants of this reasoning problem (less than or equal to, and equal
to a given size bound). In this paper, we present a thorough two-dimensional classification
of these problems: the first dimension is regarding the parameterized complexity
under a wealth of different parameterizations, and the second dimension spans
through all possible Boolean fragments of these problems in Schaefer’s constraint
satisfaction framework with co-clones (T. J. Schaefer. The complexity of satisfiability
problems. In Proceedings of the 10th Annual ACM Symposium on Theory of Computing,
May 1–3, 1978, San Diego, California, USA, R.J. Lipton, W.A. Burkhard, W.J. Savitch,
E.P. Friedman, A.V. Aho eds, pp. 216–226. ACM, 1978). Thereby, we almost complete
the parameterized complexity classification program initiated by Fellows et al.
(The parameterized complexity of abduction. In Proceedings of the Twenty-Sixth
AAAI Conference on Articial Intelligence, July 22–26, 2012, Toronto, Ontario,
Canada, J. Homann, B. Selman eds. AAAI Press, 2012), partially building on the
results by Nordh and Zanuttini (What makes propositional abduction tractable.
Artificial Intelligence, 172, 1245–1284, 2008). In this process, we outline a
fine-grained analysis of the inherent parameterized intractability of these problems
and pinpoint their FPT parts. As the standard algebraic approach is not applicable
to our problems, we develop an alternative method that makes the algebraic tools
partially available again."

text: AbstractIn order to reduce fuel consumption
and thus pollutant emissions, the automotive industry is increasingly developing
lightweight construction concepts that are accompanied by an increasing usage
of aluminum materials. Due to poor weldability of aluminum in combination with
other materials, mechanical joining methods such as clinching were developed and
established in series production. In order to predict the relevant characteristics
of clinched joints and to ensure the reliability of the process, it is simulated
numerically during product development processes. In this regard, the predictive
accuracy of the simulated process highly depends on the implemented friction model.
In particular, the frictional behavior between the sheet metals as well as between
the sheet metal and clinching tools has a significant impact on the geometrical
formation of the clinched joint. No testing methods exist that can sufficiently
investigate the frictional behavior in sheet materials, especially under high
interface pressures, different relative velocities, and long friction paths, while
allowing a decoupled consideration of the test parameters. This paper describes
the development of further testing concepts based on a proven tribo-torsion test
method for determining friction coefficients between sheet metal materials for
the simulation of clinching processes. For this purpose, the correlation of interface
pressure and the relative velocity between aluminum and steel sheet material in
clinching processes is investigated using numerical simulation. Based on these
findings, the developed concepts focus on determining friction coefficients at
interface pressures of the above materials, yield stress, as well as the reproduction
of the occurring friction conditions between sheet metal materials and tool surfaces
in clinching processes using tool substitutes. Furthermore, wear investigations
between sheet metal material and tool surface were carried out in the friction
tests with subsequent EDX analyses of the frictioned tool surfaces. The developed
method also allows an optical deformation measurement of the sheet metal material
specimen by means of digital image correlation (DIC). Based on a methodological
approach, the test setups and the test systems used are explained, and the functionality
of the concepts is proven by experimental tests using different sheet metal materials.

text: The controlled assembly of well-defined planar nanoclusters from molecular
precursors is synthetically challenging and often plagued by the predominant formation
of 3D-structures and nanoparticles. Herein, we report planar iron hydride nanoclusters
from reactions of main group element hydrides with iron(II) bis(hexamethyldisilazide).
The structures and properties of isolated Fe4, Fe6, and Fe7 nanoplatelets and
calculated intermediates enable an unprecedented insight into the underlying building
principle and growth mechanism of iron clusters, metal monolayers, and nanoparticles.

text: "Abstract\r\n Background\r\n
\ Subjective Memory Complaints (SMC) in elderly people due
to preclinical Alzheimer’s Disease may be associated with dysregulation of the
Kynurenine Pathway (KP), with an increase in neurotoxic metabolites that affect
cognition. Golf is a challenging sport with high demands on motor, sensory, and
cognitive abilities, which might bear the potential to attenuate the pathological
changes of preclinical AD. This trial investigated the feasibility of learning
to play golf for elderly with cognitive problems and its effects on cognitive
functions and the KP.\r\n \r\n Methods\r\n
\ In a 22-week single-blinded randomized controlled trial,
elderly people with SMC were allocated to the golf (n = 25,
180 min training/week) or control group (n = 21). Primary
outcomes were feasibility (golf exam, adherence, adverse events) and general cognitive
function (Alzheimer’s Disease Assessment Scale). Secondary outcomes include specific
cognitive functions (Response Inhibition, Corsi Block Tapping Test, Trail Making
Test), KP metabolites and physical performance (6-Minute-Walk-Test). Baseline-adjusted
Analysis-of-Covariance was conducted for each outcome.\r\n \r\n
\ Results\r\n 42
participants were analyzed. All participants that underwent the golf exam after
the intervention passed it (20/23). Attendance rate of the golf intervention was
75 %. No adverse events or drop-outs related to the intervention occurred. A significant
time*group interaction (p = 0.012, F = 7.050, Cohen’s
d = 0.89) was found for correct responses on the Response Inhibition task, but
not for ADAS-Cog. Moreover, a significant time*group interaction for Quinolinic
acid to Tryptophan ratios (p = 0.022, F = 5.769, Cohen’s
d = 0.84) in favor of the golf group was observed. An uncorrected negative correlation
between attendance rate and delta Quinolinic acid to Kynurenic acid ratios in
the golf group (p = 0.039, r=-0.443)
was found as well.\r\n \r\n Conclusions\r\n
\ The findings indicate that learning golf is feasible and
safe for elderly people with cognitive problems. Preliminary results suggest positive
effects on attention and the KP. To explore the whole potential of golfing and
its effect on cognitive decline, a larger cohort should be studied over a longer
period with higher cardiovascular demands.\r\n \r\n
\ Trial registration\r\n The
trial was retrospectively registered (2nd July 2018) at the German Clinical Trials
Register (DRKS00014921).\r\n

text: The continuous development of medical methods in recent decades has
achieved measurable improvement. The interdisciplinary cooperation of engineers
and physicians is a forward-looking component of this development. However, this
cooperation also results in new interfaces on the communication and software level,
which must be defined by implementing a systematic workflow. In this paper, the
step-by-step implementation of engineering methods into the surgical workflow
is shown. The focus is on the basic requirements and the necessary exchange of
information. Additively manufactured models for preoperative elucidation of the
patient are used as a psychological added value to increase the transparency of
the surgical procedure. In addition, the models serve to train young surgeons
and provide the opportunity to plan advanced surgical techniques.
