text: We demonstrate a large-scale two dimensional silicon-based optical phased
array (OPA) composed of nanoantennas with circular gratings that are balanced
in power and aligned in phase, required for producing desired radiation patterns
in the far-field. The OPAs are numerically optimized to have an upward efficiency
of up to 90%, targeting radiation concentration mainly in the field of view. We
envision that our OPAs have the ability of generating complex holographic images,
rendering them an attractive candidate for a wide range of applications like LiDAR
sensors, optical trapping, optogenetic stimulation and augmented-reality displays.

text: A key challenge in designing efficient optical phased arrays is the lack of
a well-designed radiator. This work explores horn antennas numerically optimized
to target high upward radiation efficiency to be employed in silicon-based phased
arrays capable of producing elegant radiation patterns in the far-field.

abstract:
- lang: eng
text: Metaphorical language, such as {“}spending time together{”}, projects meaning
from a source domain (here, $money$) to a target domain ($time$). Thereby, it
highlights certain aspects of the target domain, such as the $effort$ behind the
time investment. Highlighting aspects with metaphors (while hiding others) bridges
the two domains and is the core of metaphorical meaning construction. For metaphor
interpretation, linguistic theories stress that identifying the highlighted aspects
is important for a better understanding of metaphors. However, metaphor research
in NLP has not yet dealt with the phenomenon of highlighting. In this paper, we
introduce the task of identifying the main aspect highlighted in a metaphorical
sentence. Given the inherent interaction of source domains and highlighted aspects,
we propose two multitask approaches - a joint learning approach and a continual
learning approach - based on a finetuned contrastive learning model to jointly
predict highlighted aspects and source domains. We further investigate whether
(predicted) information about a source domain leads to better performance in predicting
the highlighted aspects, and vice versa. Our experiments on an existing corpus
suggest that, with the corresponding information, the performance to predict the
other improves in terms of model accuracy in predicting highlighted aspects and
source domains notably compared to the single-task baselines.

text: Globalisierung, Digitalisierung, Klimawandel, Migrationsbewegungen
und Pandemie gestalten nicht nur unseren Alltag, sondern auch die Wissenschaft
neu. Angesichts dieser gesellschaftlich tiefgreifenden Veränderungen werden Grenzen
und ihre Überwindung zu immer zentraleren Herausforderungen, auch für die pädagogischen
Forschungsfelder. Der Band versammelt vielfältige Beitrage zum Thema Entgrenzungen
und richtet dabei den Blick auf Ent- und Begrenzung in ihrer Bedeutung für Bildung,
Erziehung und Sozialisation.

text: 'The article shows how to learn models of dynamical systems from data which
are governed by an unknown variational PDE. Rather than employing reduction techniques,
we learn a discrete field theory governed by a discrete Lagrangian density $L_d$
that is modelled as a neural network. Careful regularisation of the loss function
for training $L_d$ is necessary to obtain a field theory that is suitable for
numerical computations: we derive a regularisation term which optimises the solvability
of the discrete Euler--Lagrange equations. Secondly, we develop a method to find
solutions to machine learned discrete field theories which constitute travelling
waves of the underlying continuous PDE.'

The article shows how to learn models of dynamical systems
from data which are governed by an unknown variational PDE. Rather
than employing reduction techniques, we learn a discrete field theory
governed by a discrete Lagrangian density Ld that is modelled as a neural network. Careful regularisation of the loss function for training Ld is
necessary to obtain a field theory that is suitable for numerical computations: we derive a regularisation term which optimises the solvability of
the discrete Euler–Lagrange equations. Secondly, we develop a method to
find solutions to machine learned discrete field theories which constitute
travelling waves of the underlying continuous PDE.
