text: AbstractThe use of heterogeneous materials,
such as composites with Prandtl‐Reuss‐type material laws, has increased in industrial
praxis, making finite element modeling with homogenization techniques a well‐accepted
tool. These methods are particularly advantageous to account for microstructural
mechanisms which can be related to nonlinearities and time‐dependency due to elasto‐plasticity
behavior. However, their advantages are diminished by increasing computational
demand. The present contribution deals with the balance of accuracy and numerical
efficiency of nonlinear homogenization associated with a framework of goal‐oriented
adaptivity, which takes into account error accumulation over time. To this end,
model adaptivity of homogenization methods is coupled to mesh adaptivity on the
macro scale. Our new proposed adaptive procedure is driven by a goal‐oriented
a posteriori error estimator based on duality techniques using downwind and upwind
approximations. Due to nonlinearities and time‐dependency of the plasticity, the
estimation of error transport and error generation is obtained with a backward‐in‐time
dual method despite a high demand on memory capacity. In this contribution, the
dual problem is solved with a forward‐in‐time dual method that allows estimating
the full error during the resolution of the primal problem without the need for
extra memory capacity. Finally, a numerical example illustrates the effectiveness
of the proposed adaptive approach.

text: AbstractThe constantly increasing challenges
of production technology for the economic and resource-saving production of metallic
workpieces require, among other things, the optimisation of existing processes.
Forming technology, which is confronted with new challenges regarding the quality
of the workpieces, must also organise the individual processes more efficiently
and at the same time more reliably in order to be able to guarantee good workpiece
quality and at the same time to be able to produce economically. One way to meet
these challenges is to carry out the forming processes in closed-loop control
systems using softsensors. Despite the many potential applications of softsensors
in the field of forming technology, there is still no definition of the term softsensor.
This publication therefore proposes a definition of the softsensor based on the
definition of a sensor and the distinction from the observer, which on the one
hand is intended to stimulate scientific discourse and on the other hand is also
intended to form the basis for further scientific work. Based on this definition,
a wide variety of highly topical application examples of various softsensors in
the field of forming technology are given.

text: Covalent peptidomimetic protease inhibitors have gained a lot of attention
in drug development in recent years. They are designed to covalently bind the
catalytically active amino acids through electrophilic groups called warheads.
Covalent inhibition has an advantage in terms of pharmacodynamic properties but
can also bear toxicity risks due to non-selective off-target protein binding.
Therefore, the right combination of a reactive warhead with a well-suited peptidomimetic
sequence is of great importance. Herein, the selectivities of well-known warheads
combined with peptidomimetic sequences suited for five different proteases were
investigated, highlighting the impact of both structure parts (warhead and peptidomimetic
sequence) for affinity and selectivity. Molecular docking gave insights into the
predicted binding modes of the inhibitors inside the binding pockets of the different
enzymes. Moreover, the warheads were investigated by NMR and LC-MS reactivity
assays against serine/threonine and cysteine nucleophile models, as well as by
quantum mechanics simulations.

text: In the last decade, conductive domain walls (CDWs) in single crystals of the
uniaxial model ferroelectric lithium niobate (LiNbO3; LNO) have been shown to
reach resistances more than 10 orders of magnitude lower than the resistance of
the surrounding bulk, with charge carriers being firmly confined to sheets with
a width of a few nanometers. LNO is thus currently witnessing increased attention
because of its potential in the design of room-temperature nanoelectronic circuits
and devices based on such CDWs. In this context, the reliable determination of
the fundamental transport parameters of LNO CDWs, in particular the 2D charge
carrier density n2D and the Hall mobility μH of the majority carriers, is of great
interest. In this contribution, we present and apply a robust and easy-to-prepare
Hall-effect measurement setup by adapting the standard four-probe van der Pauw
method to contact a single, hexagonally shaped domain wall that fully penetrates
the 200-μm-thick LNO bulk single crystal. We then determine n2D and μH for a set
of external magnetic fields B and prove the expected cosinelike angular dependence
of the Hall voltage. Lastly, we present photoinduced-Hall-effect measurements
of one and the same DW, by determining the impact of super-band-gap illumination
on n2D.

text: Clinical depression is a serious mental disorder that poses challenges for
both personal and public health. Millions of people struggle with depression each
year, but for many, the disorder goes undiagnosed or untreated. Over the last
decade, early depression detection on social media emerged as an interdisciplinary
research field. However, there is still a gap in detecting hesitant, depression-susceptible
individuals with minimal direct depressive signals at an early stage. We, therefore,
take up this open point and leverage posts from Reddit to fill the addressed gap.
Our results demonstrate the potential of contemporary Transformer architectures
in yielding promising predictive capabilities for mental health research. Furthermore,
we investigate the model’s interpretability using a surrogate and a topic modeling
approach. Based on our findings, we consider this work as a further step towards
developing a better understanding of mental eHealth and hope that our results
can support the development of future technologies.

text: This article presents the potential-dependent adsorption of two proteins,
bovine serum albumin (BSA) and lysozyme (LYZ), on Ti6Al4V alloy at pH 7.4 and
37 °C. The adsorption process was studied on an electropolished alloy under cathodic
and anodic overpotentials, compared to the open circuit potential (OCP). To analyze
the adsorption process, various complementary interface analytical techniques
were employed, including PM-IRRAS (polarization-modulation infrared reflection-absorption
spectroscopy), AFM (atomic force microscopy), XPS (X-ray photoelectron spectroscopy),
and E-QCM (electrochemical quartz crystal microbalance) measurements. The polarization
experiments were conducted within a potential range where charging of the electric
double layer dominates, and Faradaic currents can be disregarded. The findings
highlight the significant influence of the interfacial charge distribution on
the adsorption of BSA and LYZ onto the alloy surface. Furthermore, electrochemical
analysis of the protein layers formed under applied overpotentials demonstrated
improved corrosion protection properties. These studies provide valuable insights
into protein adsorption on titanium alloys under physiological conditions, characterized
by varying potentials of the passive alloy.

text: AbstractCurrently, the fused deposition modeling
(FDM) process is the most common additive manufacturing technology. The principle
of the FDM process is the strand wise deposition of molten thermoplastic polymers,
by feeding a filament trough a heated nozzle. Due to the strand and layer wise
deposition the cooling of the manufactured component is not uniform. This leads
to dimensional deviations which may cause the component to be unusable for the
desired application. In this paper, a method is described which is based on the
shrinkage compensation through the adaption of every single raster line in components
manufactured with the FDM process. The shrinkage compensation is based on a model
resulting from a DOE which considers the main influencing factors on the shrinkage
behavior of raster lines in the FDM process. An in‐house developed software analyzes
the component and locally applies the shrinkage compensation with consideration
of the boundary conditions, e.g., the position of the raster line in the component
and the process parameters. Following, a validation using a simple geometry is
conducted to show the effect of the presented adaptive scaling method.

text: The algorithmic imaginary as a theoretical concept has received increasing
attention in recent years as it aims at users’ appropriation of algorithmic processes
operating in opacity. But the concept originally only starts from the users’ point
of view, while the processes on the platforms’ side are largely left out. In contrast,
this paper argues that what is true for users is also valid for algorithmic processes
and the designers behind. On the one hand, the algorithm imagines users’ future
behavior via machine learning, which is supposed to predict all their future actions.
On the other hand, the designers anticipate different actions that could potentially
performed by users with every new implementation of features such as social media
feeds. In order to bring into view this permanently reciprocal interplay coupled
to the imaginary, in which not only the users are involved, I will argue for a
more comprehensive and theoretically precise algorithmic imaginary referring to
the theory of Cornelius Castoriadis. In such a perspective, an important contribution
can be formulated for a theory of social media platforms that goes beyond praxeocentrism
or structural determinism.

text: In this paper, we investigate the effect of distractions and hesitations
as a scaffolding strategy. Recent research points to the potential beneficial
effects of a speaker’s hesitations on the listeners’ comprehension of utterances,
although results from studies on this issue indicate that humans do not make strategic
use of them. The role of hesitations and their communicative function in human-human
interaction is a much-discussed topic in current research. To better understand
the underlying cognitive processes, we developed a human–robot interaction (HRI)
setup that allows the measurement of the electroencephalogram (EEG) signals of
a human participant while interacting with a robot. We thereby address the research
question of whether we find effects on single-trial EEG based on the distraction
and the corresponding robot’s hesitation scaffolding strategy. To carry out the
experiments, we leverage our LabLinking method, which enables interdisciplinary
joint research between remote labs. This study could not have been conducted without
LabLinking, as the two involved labs needed to combine their individual expertise
and equipment to achieve the goal together. The results of our study indicate
that the EEG correlates in the distracted condition are different from the baseline
condition without distractions. Furthermore, we could differentiate the EEG correlates
of distraction with and without a hesitation scaffolding strategy. This proof-of-concept
study shows that LabLinking makes it possible to conduct collaborative HRI studies
in remote laboratories and lays the first foundation for more in-depth research
into robotic scaffolding strategies.

text: AbstractWorkarounds are goal‐driven deviations
from the standard operating procedures performed to overcome obstacles constraining
day‐to‐day work. Despite starting as temporary fixes, they can become established
across an organisation and trigger the innovation of processes and IT artefacts
that can resolve misfits permanently. Although prior research has elicited antecedents
and types of workarounds, it is not known how workarounds diffuse in an organisation
and, thereby, innovating co‐workers' activities, IT artefacts, and organisational
structures. The results of our multiple two‐year case study provide unique empirical
insights into the diffusion of workarounds and how they can act as generative
mechanisms for bottom‐up process innovation.

text: AbstractCold‐box sand (CBS) belongs to the
granular materials and consists of sand and a binder. The behavior of CBS is simulated
with a micropolar model, whereby the additional degree of freedom of the model
describes the rotation of the sand grains. The model is used to generate a shear
band under pressure for three different meshes, where the force‐displacement curves
of the three meshes converge so that no mesh dependence occurs. Another requirement
of the model is the consideration of asymmetric behavior for compression and tension.
Due to the additional degree of freedom the implicit implementation of the micropolar
continuum is very time‐consuming. Therefore, an explicit implementation is considered
as an alternative possibility. This paper compares the advantages and disadvantages
of both methods and the results for both calculations.

text: Photoactive chromium(III) complexes saw a conceptual breakthrough with the
discovery of the prototypical molecular ruby mer-[Cr(ddpd)2]3+ (ddpd = N,N′-dimethyl-N,N′-dipyridin-2-ylpyridine-2,6-diamine),
which shows intense long-lived near-infrared (NIR) phosphorescence from metal-centered
spin-flip states. In contrast to the numerous studies on chromium(III) photophysics,
only 10 luminescent molybdenum(III) complexes have been reported so far. Here,
we present the synthesis and characterization of mer-MoX3(ddpd) (1, X = Cl; 2,
X = Br) and cisfac-[Mo(ddpd)2]3+ (cisfac-[3]3+), an isomeric heavy homologue of
the prototypical molecular ruby. For cisfac-[3]3+, we found strong zero-field
splitting using magnetic susceptibility measurements and electron paramagnetic
resonance spectroscopy. Electronic spectra covering the spin-forbidden transitions
show that the spin-flip states in mer-1, mer-2, and cisfac-[3]3+ are much lower
in energy than those in comparable chromium(III) compounds. While all three complexes
show weak spin-flip phosphorescence in NIR-II, the emission of cisfac-[3]3+ peaking
at 1550 nm is particularly low in energy. Femtosecond transient absorption spectroscopy
reveals a short excited-state lifetime of 1.4 ns, 6 orders of magnitude shorter
than that of mer-[Cr(ddpd)2]3+. Using density functional theory and ab initio
multireference calculations, we break down the reasons for this disparity and
derive principles for the design of future stable photoactive molybdenum(III)
complexes.

text: AbstractThe time‐dependent adjustment of
a system's power demand simultaneously with current power generation is commonly
referred to as demand side management (DSM). DSM strategies are based on the flexibility
to purchase electricity at times when prices are low, which can result in monetary
benefits. One option to increase the flexibility of continuously operated processes
is to oversize them. From an economic point of view, this leads to an increased
investment. DSM only serves an economic purpose if the monetary benefits exceed
this increase in capital costs. The main goal of this contribution is to develop
a decision support tool to help evaluate unit operations regarding their feasibility
for DSM implementation. In a case study, the decision support tool was applied
to show its functionality on a biomethane production plant. The results show that
with the help of the decision support tool, evaluating unit operations concerning
their economic DSM potential is possible.

text: AbstractIn Konstruktionen des Landmaschinenbaus
aus dickeren Blechen (ca. 3–10 mm) findet die Klebtechnik bislang nur wenig Anwendung,
obwohl sie in anderen Einsatzgebieten bereits ein etabliertes Fügeverfahren darstellt
und viele Vorteile gegenüber anderen Fügeverfahren bietet, da es bisher an Regelwerken
bei der Auslegung derartiger Verbindungen fehlt. Ein wesentliches Kriterium bei
der Auslegung von Verbindungen im Landmaschinenbau ist die Ermüdungsfestigkeit
aufgrund der langen Nutzungsphase der Produkte und der in der Landtechnik vorherrschenden
Belastungscharakteristika. Geklebte Verbindungen weisen ein hervorragendes Verhalten
bei zyklischer Belastung auf. Die steigenden Anforderungen im Hinblick auf Ressourceneffizienz
und Leichtbau führen zu einem Umdenken, da durch den vermehrten Einsatz höherfester
Stahlwerkstoffe in Kombination mit der Klebtechnik dieses als umsetzbar erscheint.
Ziel ist die Entwicklung einer Methode zur Auslegung geklebter Verbindungen in
Konstruktionen mit höherfesten Stahlwerkstoffen in Anlehnung an die FKM‐Richtlinie.
Die betriebsrelevanten Beanspruchungen der Landtechnik werden analysiert und an
speziellen Probekörpern untersucht. Dabei werden sowohl die mechanischen, thermischen
und medialen Einflussfaktoren als auch der Einfluss der Klebfugengeometrie und
von Betriebslastenkollektiven untersucht. Die Erkenntnisse werden in einer KMU‐relevanten
Vorgehensweise zur Ermittlung von Abminderungsfaktoren zusammengefasst, wodurch
die Auslegung der Bauteilfestigkeit sowohl statisch als auch dynamisch möglich
ist.

text: Lubricants play a central role in many technical applications, e.g.
in bearings and gears as well as in machining processes. In such applications,
lubricants are exposed to extreme conditions in the contact area. In lubrication
gaps, the pressure can reach values up to 5 GPa. The thermophysical properties
of lubricants, and in particular the viscosity, at such extreme conditions have
an important influence on the friction and wear behavior of a tribosystem. Accordingly,
reliable lubricant property models are a prerequisite for accurate tribological
simulations, e.g. elastohydrodynamic lubrication (EHL) simulations. Presently,
the vast majority of experimental thermophysical property data are only available
up to 1 GPa. Thus, reliable and robust models with strong extrapolation capabilities
to higher pressure are required. In this work, viscosity measurements of squalane
in a temperature range be tween 20 °C and 100 °C and pressures up to 1 GPa were
carried out. Based on that data, a physical model for the viscosity was developed.
The model is built by combining a molecular-based equation of state with the so-called
entropy scaling approach. Finally, we demonstrate how this fluid property model
can be favorably integrated in an EHL simulation by an application programming
interface (API). The novel hybrid modeling approach is promising for future applications.
