text: "Dispersion is present in every optical setup and is often an undesired effect,
especially in nonlinear-optical experiments where ultrashort laser pulses are
needed. Typically, bulky pulse compressors consisting of gratings or prisms are
used\r\nto address this issue by precompensating the dispersion of the optical
components. However, these devices are only able to compensate for a part of the
dispersion (second-order dispersion). Here, we present a compact pulse-shaping
device that uses plasmonic metasurfaces to apply an arbitrarily designed spectral
phase delay allowing for a full dispersion control. Furthermore, with specific
phase encodings, this device can be used to temporally reshape the incident laser
pulses into more complex pulse forms such as a double pulse. We verify the performance
of our device by using an SHG-FROG measurement setup together with a retrieval
algorithm to extract the dispersion that our device applies to an incident laser
pulse."

text: Hydrothermal carbonization (HTC) is an efficient thermochemical method for
the conversion of organic feedstock to carbonaceous solids. HTC of different saccharides
is known to produce microspheres (MS) with mostly Gaussian size distribution,
which are utilized as functional materials in various applications, both as pristine
MS and as a precursor for hard carbon MS. Although the average size of the MS
can be influenced by adjusting the process parameters, there is no reliable mechanism
to affect their size distribution. Our results demonstrate that HTC of trehalose,
in contrast to other saccharides, results in a distinctly bimodal sphere diameter
distribution consisting of small spheres with diameters of (2.1 ± 0.2) μm and
of large spheres with diameters of (10.4 ± 2.6) μm. Remarkably, after pyrolytic
post-carbonization at 1000 °C the MS develop a multimodal pore size distribution
with abundant macropores > 100 nm, mesopores > 10 nm and micropores < 2 nm, which
were examined by small-angle X-ray scattering and visualized by charge-compensated
helium ion microscopy. The bimodal size distribution and hierarchical porosity
provide an extraordinary set of properties and potential variables for the tailored
synthesis of hierarchical porous carbons, making trehalose-derived hard carbon
MS a highly promising material for applications in catalysis, filtration, and
energy storage devices.

text: Dielectric metasurfaces provide a unique platform for efficient harmonic generation
and optical wavefront manipulation at the nanoscale. Tailoring phase and amplitude
of a nonlinearly generated wave with a high emission efficiency using resonance-based
metasurfaces is a challenging task that often requires state-of-the-art numerical
methods. Here, we propose a simple yet effective approach combining a sampling
method with a Monte Carlo approach to design the third-harmonic wavefront generated
by all-dielectric metasurfaces composed of elliptical silicon nanodisks. Using
this approach, we theoretically demonstrate the full nonlinear 2π phase control
with a uniform and highest possible amplitude in the considered parameter space,
allowing us to design metasurfaces operating as third harmonic beam deflectors
capable of steering light into a desired direction with high emission efficiency.
The TH beam deflection with a record calculated average conversion efficiency
of 1.2 × 10–1 W–2 is achieved. We anticipate that the proposed approach will be
widely applied as alternative to commonly used optimization algorithms with higher
complexity and implementation effort for the design of metasurfaces with other
holographic functionalities.

abstract:
- lang: eng
text: Faradaic reactions including charge transfer are often accompanied with diffusion
limitation inside the bulk. Conductive two-dimensional frameworks (2D MOFs) with
a fast ion transport can combine both - charge transfer and fast diffusion inside
their porous structure. To study remaining diffusion limitations caused by particle
morphology, different synthesis routes of Cu-2,3,6,7,10,11-hexahydroxytriphenylene
(Cu3(HHTP)2), a copper-based 2D MOF, are used to obtain flake- and rod-like MOF
particles. Both morphologies are systematically characterized and evaluated for
redox-active Li+ ion storage. The redox mechanism is investigated by means of
X-ray absorption spectroscopy, FTIR spectroscopy and in situ XRD. Both types are
compared regarding kinetic properties for Li+ ion storage via cyclic voltammetry
and impedance spectroscopy. A significant influence of particle morphology for
2D MOFs on kinetic aspects of electrochemical Li+ ion storage can be observed.
This study opens the path for optimization of redox active porous structures to
overcome diffusion limitations of Faradaic processes.

text: A series of new organic donor–π–acceptor dyes incorporating a diquat moiety
as a novel electron-acceptor unit have been synthesized and characterized. The
analytical data were supported by DFT calculations. These dyes were explored in
the aerobic thiocyanation of indoles and pyrroles. Here they showed a high photocatalytic
activity under visible light, giving isolated yields of up to 97 %. In addition,
the photocatalytic activity of standalone diquat and methyl viologen through formation
of an electron donor acceptor complex is presented.

text: As a benchmark, the structural, electronic and optical properties of the three
main phases of TiO$\rm{_2}$ crystals have been calculated using Hubbard U correction
and hybrid functional methods in density-functional theory. These calculations
are compared concerning the available experimental observations on pristine TiO$\rm{_2}$
crystals. Modified hybrid functionals, particularly the PBE0 functional with 11.4%
fraction of exact exchange, are shown to provide highly accurate atomic structures
and also accurate electronic structure data, including optical excitation energies.
With $\rm{DFT+U}$, accurate optical spectra are also possible, but only if the
Hubbard U is applied on the O $\rm2p$ electrons exclusively. Furthermore, both
methods, the 11.4%-PBE0 hybrid functional and the $\rm{DFT+U_p}$ scheme have been
used to study TiO$\rm{_2}$ amorphous ultra-thin films, confirming the agreement
of the two methods even with respect to small details of the optical spectra.
Our results show that the proposed $\rm{DFT+U_p}$ methodology is computationally
efficient, but still accurate. It can be applied to well-ordered TiO$\rm{_2}$
polymorphs as well as to amorphous TiO$\rm{_2}$ and will allow for the calculations
of complex titania-based structures.

text: The development of automotive components with reduced greenhouse gas
(GHG) emissions is needed to reduce overall vehicle emissions. Life Cycle Engineering
(LCE) based on Life Cycle Assessment (LCA) supports this by providing holistic
information and improvement potentials regarding eco-efficient products. Key factors
influencing LCAs of automotive components, such as material production, will change
in the future. First approaches for integrating future scenarios for these key
factors into LCE already exist, but they only consider a limited number of parameters
and scenarios. This work aims to develop a method that can be practically applied
in the industry for integrating prospective LCAs (pLCA) into the LCE of automotive
components, considering relevant parameters and consistent scenarios. Therefore,
pLCA methods are further developed to investigate the influence of future scenarios
on the GHG emissions of automotive components. The practical application is demonstrated
for a vehicle component with different design options. This paper shows that different
development paths of the foreground and background system can shift the ecological
optimum of design alternatives. Therefore, future pathways of relevant parameters
must be considered comprehensively to reduce GHG emissions of future vehicles.
This work contributes to the methodological and practical integration of pLCA
into automotive development processes and provides quantitative results.

text: The notion of neural collapse refers to several emergent phenomena that have
been empirically observed across various canonical classification problems. During
the terminal phase of training a deep neural network, the feature embedding of
all examples of the same class tend to collapse to a single representation, and
the features of different classes tend to separate as much as possible. Neural
collapse is often studied through a simplified model, called the unconstrained
feature representation, in which the model is assumed to have "infinite expressivity"
and can map each data point to any arbitrary representation. In this work, we
propose a more realistic variant of the unconstrained feature representation that
takes the limited expressivity of the network into account. Empirical evidence
suggests that the memorization of noisy data points leads to a degradation (dilation)
of the neural collapse. Using a model of the memorization-dilation (M-D) phenomenon,
we show one mechanism by which different losses lead to different performances
of the trained network on noisy data. Our proofs reveal why label smoothing, a
modification of cross-entropy empirically observed to produce a regularization
effect, leads to improved generalization in classification tasks.

text: "Label noise poses an important challenge in machine learning, especially
in\r\ndeep learning, in which large models with high expressive power dominate
the\r\nfield. Models of that kind are prone to memorizing incorrect labels, thereby\r\nharming
generalization performance. Many methods have been proposed to address\r\nthis
problem, including robust loss functions and more complex label correction\r\napproaches.
Robust loss functions are appealing due to their simplicity, but\r\ntypically
lack flexibility, while label correction usually adds substantial\r\ncomplexity
to the training setup. In this paper, we suggest to address the\r\nshortcomings
of both methodologies by \"ambiguating\" the target information,\r\nadding additional,
complementary candidate labels in case the learner is not\r\nsufficiently convinced
of the observed training label. More precisely, we\r\nleverage the framework of
so-called superset learning to construct set-valued\r\ntargets based on a confidence
threshold, which deliver imprecise yet more\r\nreliable beliefs about the ground-truth,
effectively helping the learner to\r\nsuppress the memorization effect. In an
extensive empirical evaluation, our\r\nmethod demonstrates favorable learning
behavior on synthetic and real-world\r\nnoise, confirming the effectiveness in
detecting and correcting erroneous\r\ntraining labels."

text: 'Many applications require explainable node classification in knowledge graphs.
Towards this end, a popular ``white-box'''' approach is class expression learning:
Given sets of positive and negative nodes, class expressions in description logics
are learned that separate positive from negative nodes. Most existing approaches
are search-based approaches generating many candidate class expressions and selecting
the best one. However, they often take a long time to find suitable class expressions.
In this paper, we cast class expression learning as a translation problem and
propose a new family of class expression learning approaches which we dub neural
class expression synthesizers. Training examples are ``translated'''' into class
expressions in a fashion akin to machine translation. Consequently, our synthesizers
are not subject to the runtime limitations of search-based approaches. We study
three instances of this novel family of approaches based on LSTMs, GRUs, and set
transformers, respectively. An evaluation of our approach on four benchmark datasets
suggests that it can effectively synthesize high-quality class expressions with
respect to the input examples in approximately one second on average. Moreover,
a comparison to state-of-the-art approaches suggests that we achieve better F-measures
on large datasets. For reproducibility purposes, we provide our implementation
as well as pretrained models in our public GitHub repository at https://github.com/dice-group/NeuralClassExpressionSynthesis'
