text: Due to their devastating consequences, so-called century floods attract significant
public attention and are therefore covered in nationwide media. In journalistic
reporting, numerous conceptual metaphors are used to conceptualise such extreme
weather events. This linguistic study investigates how the century flood that
occurred in southern Germany in late May and early June 2024 was metaphorically
conceptualised in nationwide online journalism by identifying patterns of metaphorical
conceptualisation. The analysis draws on the foundations of Conceptual Metaphor
Theory as proposed by Lakoff and Johnson (1980), refined through the graded distinction
of schematicity levels in conceptual structure proposed in Kövecses (2017, 2020,
2022) Extended Conceptual Metaphor Theory. Accordingly, metaphors are understood
as schematically distinguishable mappings of conceptual aspects from source to
target areas, through which particular actions are constituted. Adopting a mixed-methods
approach that integrates manual with (semi-)automatic analytical procedures, the
study reveals that the century flood is predominantly conceptualised through the
highly schematic metaphor ZEIT IST SUBSTANZ (›time is substance‹), the less schematic
metaphor NATURKATASTROPHEN SIND PERSONEN (›natural disasters are persons‹), and
a set of least schematic, elaborating metaphors, namely HOCHWASSER IST GEGNER
(›flood is an opponent‹), HOCHWASSER IST ZERSTÖRER (›flood is a destroyer‹) and
HOCHWASSER IST MÖRDER (›flood is a murderer‹). From an ecolinguistic perspective,
the study critically reflects on how these metaphorical conceptualisations obscure
human co-responsibility for the intensity of extreme flood events.

text: 'Modern software development reuses code by importing libraries as dependencies.
Software projects typically include an average of 36 dependencies, with 80% being
transitive, meaning they are dependencies of dependencies. Recent research indicates
that only 24.9% of these dependencies are required at runtime, and even within
those, many program constructs remain unused, adding unnecessary code to the project.
This has led to the development of debloating tools that remove unnecessary dependencies
and program constructs while balancing precision by eliminating unused constructs
and soundness by preserving all required constructs. To systematically evaluate
this trade-off, we developed Deblometer, a micro-benchmark consisting of 59 test
cases designed to assess support for various Java language features in debloating
tools. Each test case includes a manually curated ground truth specifying necessary
and bloated classes, methods, and fields, enabling precise measurement of soundness
and precision. Using Deblometer, we evaluated three popular Java debloating tools:
Deptrim, JShrink, and ProGuard. Our evaluation reveals that all tools remove required
program constructs, which results in changed semantics or execution crashes. In
particular, the dynamic class loading feature introduces unsoundness in all evaluated
tools. Our comparison shows that Deptrim retains more bloated constructs, while
ProGuard removes more required constructs. JShrink’s soundness is significantly
affected by limited support for annotations, which leads to corrupted debloated
artifacts. These soundness issues highlight the need to improve debloating tools
to ensure stable and reliable debloated software.'

text: "Abstract\r\n The increasing
use of thin-walled profiles in automotive battery housing construction is leading
to a growing demand for one-sided access mechanical fasteners. Currently, the
installation of blind rivet nuts still requires pre-drilling using chip-forming
operations. In Meschut and Meyer (Vorlochfreies Setzen von Funktionselementen
mittels Fließformen, Europäische Forschungsgesellschaft für Blechverarbeitung
e.V. (EFB), Hannover, 2021), a chipless, two-step method for installing blind
rivet nuts was developed, in which flow-drilling is the initial step. To eliminate
the pre-drilling operation and optimise the joining process of blind rivet nuts,
a pilot-hole-free joining method using a flow-drilling process is being pursued.
The use of these blind rivet nuts can significantly simplify the joining process
by eliminating chip-forming pre-drilling operations. Additionally, the screw-through
capability reduces screw variance in automated fastening, optimising the feeding
process by minimising the risk of incorrect screw selection. This work aims to
develop a single-step process for the installation of a blind rivet nut. To achieve
this, it is necessary to design the geometries of both the blind rivet nut and
the flow-drill former, which also serves as the mandrel for the blind rivet nut.
In addition to the geometries of the tools and functional elements, the flow-drilling
process itself has been developed. Special attention is given to the pull-through
and the formation of the closing head. To optimise the closing head formation,
an iterative optimization process was used. The quality of the pull-through is
improved by varying the tip geometries and adjusting the process parameters during
flow-drilling."

text: "\r\n We develop a framework for identifying nonclassical
speedups in systems with polarization, likewise spin degrees of freedom. By confining
the dynamics to the manifold of angular momentum coherent states, which act as
the classical reference in this case, we compute the speed limit that bounds the
rate of change of the state achievable without generating quantum coherence. A
comparison with the unrestricted quantum speed limit enables the quantitative
identification of speedups arising from polarization nonclassicality. We apply
this framework to the cross-Kerr interaction, demonstrating a persistent speedup
scaling as\r\n \r\n
\ \r\n O\r\n
\ (\r\n \r\n
\ N\r\n \r\n
\ )\r\n \r\n
\ \r\n with the photon number\r\n
\ \r\n
\ N\r\n \r\n ,
with a parity effect in favor of even photon numbers. The results establish polarization
nonclassicality as a genuine dynamical resource, linking quantum coherence to
quantum-enhanced evolution speeds in nonlinear photonic systems.\r\n "

text: "In this work, we build a bridge between the Pólya--Schur program and Voiculescu's
free probability theory. A cornerstone of the former is the Pólya--Benz Theorem,
classifying a central family of real-root preserving operators on the space of
polynomials, as those given by $f(\\partial_z)$ for a Laguerre--Pólya function
$f$ and the derivative operator $\\partial_{z}$. We prove that any free (additive)
infinitely divisible distribution can be attained as the weak limit of root distributions
of Appell polynomials $f_n(\\partial_z)z^n$ as $n\\to\\infty$, for a suitably
chosen sequence $f_n$ of Laguerre--Pólya functions.\r\n Such questions on the
(global) limiting distributions of real rooted polynomials belong to the active
research area of finite free probability. In contrast to its standard tools, our
approach allows for non-compactly supported limiting distributions, (barely) complex
rooted polynomials and even provides the full microscopic description of the roots.
Moreover, we extend our results to differential operators generating free multiplicative
infinitely divisible distributions, to the rectangular free convolution, and to
$f_n(\\partial_z)p_n$ for real rooted polynomials $p_n$, implying a generalization
of the recent connections between the heat flow and free Brownian motion to any
free Lévy process.\r\n As corollaries, we identify free stable distributions
by choosing $f_n$ to be a fixed rescaled Laguerre--Pólya function, and we prove
various convergence results on the zero distributions of Jensen polynomials, e.g.
the limiting root distribution of Jensen polynomial of the Riemann $Ξ$-function
is given by the Cauchy distribution."

text: Efficient detection of near-infrared light at telecommunication wavelengths
remains a central challenge for GaAs-based photonic and optoelectronic devices
due to the absence of linear absorption below the bandgap. Here, we demonstrate
a hybrid nonlinear optoelectronic device that enhances the detection efficiency
of a (001)-oriented GaAs PIN photodiode under telecommunication-wavelength illumination,
where absorption is intrinsically limited to two-photon absorption (2PA). Our
approach relies on the integration of a transferred, nanopatterned 385 nm-thick
(111)-oriented GaAs nanofilm acting as an on-chip nonlinear frequency-conversion
layer. Elliptical GaAs nanoresonators are employed to enhance second-harmonic
generation (SHG) resonantly, converting incident 1550 nm radiation into above-bandgap
photons efficiently absorbed by the underlying diode. Spatially resolved current–voltage
measurements reveal a pronounced enhancement of the detector response in regions
covered by the nanoantennas. The device exhibits a low dark current, while the
metasurface-covered regions show the largest current response under 1560 nm excitation
compared to the bare GaAs(100) diode and the unstructured GaAs(111) film. These
results establish a direct functional link between dielectric metasurface–based
nonlinear frequency conversion and electrical photodetection, providing a viable
route toward integrated sub-bandgap detection schemes.
