text: Modified action demonstration—dubbed motionese—has
been proposed as a way to help children recognize the structure and meaning of
actions. However, until now, it has been investigated only in young infants. This
brief research report presents findings from a cross-sectional study of parental
action demonstrations to three groups of 8–11, 12–23, and 24–30-month-old children
that applied seven motionese parameters; a second study investigated the youngest
group of participants longitudinally to corroborate the cross-sectional results.
Results of both studies suggested that four motionese parameters (Motion Pauses,
Pace, Velocity, Acceleration) seem to structure the action by organizing it in
motion pauses. Whereas these parameters persist over different ages, three other
parameters (Demonstration Length, Roundness, and Range) occur predominantly in
the younger group and seem to serve to organize infants' attention on the basis
of movement. Results are discussed in terms of facilitative vs. pedagogical learning.

text: Metadata are a very broad and extremely differentiated subject and ranges
from rudimentary catalog data to deeply indexed scientific catalogs (e.g., catalogs
of works). In this paper, the concept of metadata in the context of MEI is first
examined, before two examples are used to show that metadata are more than just
rudimentary descriptions. These examples are also intended to illustrate the extent
to which metadata are encoded in the field of music philology and thus represent
an attempt to create a little more awareness for the work of the Metadata and
Cataloging Interest Group of MEI. The examples deal on the one hand with the encoding
of performance resources and on the other hand with watermarks. In both cases,
the possibilities of metadata encoding with MEI version 4 are exhausted and it
is discussed which steps are useful and necessary to create an even deeper, machine-readable
structure so that these sub-fields of the MEI metadata can also be used for larger
scientific purposes such as analyses.

text: In many manufacturing areas, multi-material designs are implemented
in which individual components are joined together to form complex structures
with numerous joints. For example, in the automotive sector, cast components are
used at the junctions of the body and joined with different types of sheet metal
and extruded profiles. To be able to join structures consisting of different materials,
alternative joining technologies have emerged in recent years. This includes clinching,
which allows assembling of two or more thin sheet metal and casting parts by solely
cold forming the material. Clinching the brittle and usually less ductile cast
aluminium alloys remains a challenge because the brittle character of the cast
aluminium alloys can cause cracks during the forming of the clinched joint. In
this study, the influence of the heat treatment time of an aluminium casting alloy
AlSi9 on the joinability in the clinching process is investigated. Specific heat
treatment of the naturally hard AlSi9 leads to a modification of the eutectic
microstructure, which can increase ductility. Based on this, it will be examined
if specific clinching die geometries can be used, which achieve an optimized geometrical
formation of the clinched joint. The load-bearing capacities of the clinched joints
are determined and compared by shear tensile and head tensile tests. Furthermore,
the joints are examined microscopically to investigate the influence of the heat
treatment on the failure behaviour during the load-bearing tests as well as crack
initiation within the joining process.

text: In modern vehicle chassis, multi-material design is implemented to apply the
appropriate material for each functionality. In spaceframe technology, both sheet
metal and continuous cast are joined to castings at the nodal points of the chassis.
Since resistance spot welding is not an option when different materials are joined,
research is focusing on mechanical joining methods for multi-material designs.
To reduce weight and achieve the required strength, hardenable cast aluminium
alloys of the AlSi-system are widely used. Thus, 85–90% of aluminium castings
in the automotive industry are comprised of the AlSi-system. Due to the limited
weldability, mechanical joining is a suitable process. For this application, various
optimisation strategies are required to produce a crack-free joint, as the brittle
character of the AlSi alloy poses a challenge. Thus, adapted castings with appropriate
ductility are needed. Hence, in this study, the age-hardenable cast aluminium
alloy AlSi10Mg is investigated regarding the correlation of the different thicknesses,
the microstructural characteristics as well as the resulting mechanical properties.
A variation of the thicknesses leads to different solidification rates, which
in turn affect the microstructure formation and are decisive for the mechanical
properties of the casting as well as the joinability. For the investigation, plates
with thicknesses from 2.0 to 4.0 mm, each differing by 0.5 mm, are produced via
sand casting. Hence, the overall aim is to evaluate the joinability of AlSi10Mg
and derive conclusions concerning the microstructure and mechanical properties.

text: 'Clinching as a mechanical joining technique allows a fast and reliable joining
of metal sheets in large-scale production. An efficient design and dimensioning
of clinched joints requires a holistic understanding of the material, the joining
process and the resulting properties of the joint. In this paper, the process
chain for clinching metal sheets is described and experimental techniques are
proposed to analyze the process-microstructure-property relationships from the
sheet metal to the joined structure. At the example of clinching aluminum EN AW
6014, characterization methods are applied and discussed for the following characteristics:
the mechanical properties of the sheet materials, the tribological behavior in
the joining system, the joining process and the resulting material structure,
the load-bearing behavior of the joint, the damage and degradation as well as
the service life and crack growth behavior. The compilation of the characterization
methods gives an overview on the advantages and weaknesses of the methods and
the multiple interactions of material, process and properties during clinching.
In addition, the results of the analyses on EN AW 6014 can be applied for parameterization
and validation of simulations.'

text: The third‐order susceptibility of lithium
niobate (LiNbO3) is calculated within a Berry‐phase formulation
of the dynamical polarization based on the electronic structure obtained within
density‐functional theory (DFT). Maximum values of the order of m V are calculated
for photon energies between 1.2 and 2 eV, i.e., in the lower half of the optical
bandgap of lithium niobate. Both free and bound electron (bi)polarons are found
to lead to a remarkable enhancement of the third‐order susceptibility for photon
energies below 1 eV.

text: Optical traveling wave antennas offer unique opportunities to control and
selectively guide light into a specific direction, which renders them excellent
candidates for optical communication and sensing. These applications require state-of-the-art
engineering to reach optimized functionalities such as high directivity and radiation
efficiency, low sidelobe levels, broadband and tunable capabilities, and compact
design. In this work, we report on the numerical optimization of the directivity
of optical traveling wave antennas made from low-loss dielectric materials using
full-wave numerical simulations in conjunction with the particle swarm optimization
algorithm. The antennas are composed of a reflector and a director deposited on
a glass substrate, and an emitter placed in the feed gap between them serves as
an internal source of excitation. In particular, we analyze antennas with rectangular-
and horn-shaped directors made of either hafnium dioxide or silicon. The optimized
antennas produce highly directional emissions due to the presence of two dominant
guided TE modes in the director in addition to leaky modes. These guided modes
dominate the far-field emission pattern and govern the direction of the main lobe
emission, which predominately originates from the end facet of the director. Our
work also provides a comprehensive analysis of the modes, radiation patterns,
parametric influences, and bandwidths of the antennas, which highlights their
robust nature.

text: We study a double-scattering coherent mechanism of negative polarization (NP)
near opposition that is observed for powder-like surfaces. The problem is solved
numerically for absorbing structures with irregular constituents, cubes, spheres,
and ellipsoids larger than the wavelength of incident light. Our simulations show
that double scattering between two random irregular particles shows weak NP. Adding
one more particle significantly increases the relative contribution of double
scattering which enhances NP. Simulations with regular shapes and controlled geometric
parameters show that the interference mechanism is sensitive to the geometry of
the scattering system and can also result in no polarization or even strong enhancement
of positive polarization at backscattering.

text: Highly directive antennas with the ability of shaping radiation patterns in
desired directions are essential for efficient on-chip optical communication with
reduced cross talk. In this paper, we design and optimize three distinct broadband
traveling-wave tantalum pentoxide antennas exhibiting highly directional characteristics.
Our antennas contain a director and reflector deposited on a glass substrate,
which are excited by a dipole emitter placed in the feed gap between the two elements.
Full-wave simulations in conjunction with global optimization provide structures
with an enhanced linear directivity as high as 119 radiating in the substrate.
The high directivity is a result of the interplay between two dominant TE modes
and the leaky modes present in the antenna director. Furthermore, these low-loss
dielectric antennas exhibit a near-unity radiation efficiency at the operational
wavelength of 780 nm and maintain a broad bandwidth. Our numerical results are
in good agreement with experimental measurements from the optimized antennas fabricated
using a two-step electron-beam lithography, revealing the highly directive nature
of our structures. We envision that our antenna designs can be conveniently adapted
to other dielectric materials and prove instrumental for inter-chip optical communications
and other on-chip applications.

text: As AI is more and more pervasive in everyday life, humans have an increasing
demand to understand its behavior and decisions. Most research on explainable
AI builds on the premise that there is one ideal explanation to be found. In fact,
however, everyday explanations are co-constructed in a dialogue between the person
explaining (the explainer) and the specific person being explained to (the explainee).
In this paper, we introduce a first corpus of dialogical explanations to enable
NLP research on how humans explain as well as on how AI can learn to imitate this
process. The corpus consists of 65 transcribed English dialogues from the Wired
video series 5 Levels, explaining 13 topics to five explainees of different proficiency.
All 1550 dialogue turns have been manually labeled by five independent professionals
for the topic discussed as well as for the dialogue act and the explanation move
performed. We analyze linguistic patterns of explainers and explainees, and we
explore differences across proficiency levels. BERT-based baseline results indicate
that sequence information helps predicting topics, acts, and moves effectively.

text: In industrial x-ray computed tomography (CT), the application of more complex
scan paths in comparison to the typical circular trajectory (${360}^{\circ}$ rotation
of the measurement object) can extend the potential of CT. One way to enable such
3D scan trajectories is to use a 6-degrees-of-freedom (DOF) object manipulator
system. In our case, a hexapod is mounted on top of the rotary table of a commercial
CT scanner. This allows for adaptive tilting of the measurement object during
the scan. For high accuracy, the geometry calibration of such setups is typically
done using the x-ray projections of a calibrated multi-sphere object. Contrary
to this, here, we demonstrate a procedure that is based on only a single sphere
and can therefore experimentally be implemented with low effort. Using the intrinsic
geometry parameters of the CT device as prior information, the hexapod coordinate
system with respect to the CT machine coordinate system is determined by means
of a one-step optimization approach. The resulting parameters are used to calculate
projection matrices that enable the volume reconstruction for 3D scan trajectories.
The method is validated using simulated x-ray images and experimental investigations
including dimensional measurements. For the used setup, geometric measurement
results for 3D scan trajectories that are calibrated with the presented method
show in sum increased errors compared to the circular scans. A limited pose accuracy
of the manipulator system is discussed as a potential cause. The results nevertheless
indicate that the presented method is generally feasible for dimensional CT measurements
provided that the pose accuracy is sufficient. The calibration procedure can therefore
be a low-cost and easier to implement alternative compared to trajectory calibration
methods based on multi-sphere objects, but with a tendency towards lower measurement
accuracy. The methodology can in principle be transferred to different setups
with 6-DOF manipulator systems, e.g. C-arm CT devices with a robot arm.

text: Many mechanical material properties show a dependence on the strain
rate, e.g. yield stress or elongation at fracture. The quantitative description
of the material behavior under dynamic loading is of major importance for the
evaluation of crash safety. This is carried out using numerical methods and requires
characteristic values for the materials used. For the standardized determination
of dynamic characteristic values in sheet metal materials, tensile tests performed
according to the guideline from [1]. A particular challenge in dynamic tensile
tests is the force measurement during the test. For this purpose, strain gauges
are attached on each specimen, wired to the measuring equipment and calibrated.
This is a common way to determine a force signal that is as low in vibration and
as free of bending moments as possible. The preparation effort for the used strain
gauges are enormous. For these reasons, an optical method to determine the force
by strain measurement using DIC is presented. The experiments are carried out
on a high speed tensile testing system. In combioantion with a 3D DIC high speed
system for optical strain measurement. The elastic deformation of the specimen
in the dynamometric section is measured using strain gauges and the optical method.
The measured signals are then compared to validate the presented method. The investigations
are conducted using the dual phase steel material HCT590X and the aluminum material
EN AW-6014 T4. Strain rates of up to 240 s-1 are investigated.

text: Companies show an increasing interest in low-code development platforms to
facilitate application development by domain experts without sophisticated software
development knowledge. Thus, companies aim for a more efficient development of
more effective applications since domain experts as so-called citizen developers
are no longer limited by the availability and domain knowledge of trained software
developers. Nevertheless, efficiency and effectiveness of application development
is traditionally also largely influenced by the use of a suitable software development
method. Domain experts are, however, not trained in software development methods.
This introduces a risk of domain experts creating unusable applications or exceeding
the designated time frame of a project (or both). In this paper, we therefore
propose an initial version of a situational software development method which
supports domain experts in manufacturing companies during the low-code development
of applications. The method can be tailored based on situational factors, considering
application requirements, features of the used low-code development platform,
and characteristics of the development team. We also present feedback corroborating
the usefulness of our method and future extension points based on expert interviews.
