text: "In the Bogoliubov-Fr\\\"ohlich model, we prove that an impurity immersed
in a\r\nBose-Einstein condensate forms a stable quasi-particle when the total
momentum\r\nis less than its mass times the speed of sound. The system thus exhibits\r\nsuperfluid
behavior, as this quasi-particle does not experience friction. We do\r\nnot assume
any infrared or ultraviolet regularization of the model, which\r\ncontains massless
excitations and point-like interactions."

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: I study the effect of heterogeneous beliefs about asset prices on the long-term
behavior of financial markets. Starting from the ideas of Abreu and Brunnermeier
(Citation2003), a two-dimensional system of differential equations is developed.
The first dynamic variable is the asset price growth rate. The second dynamic
variable is the number of investors who believe that asset prices are abnormally
high. In a phase plane analysis, I find both stable and unstable equilibria, depending
on the spread of information and the response to other agents’ beliefs. If individuals
try to increase their returns while perceiving more overpricing, these equilibria
can be spirals or even approach limit cycles. Although I intend to study general
price patterns, abnormally high asset prices can be caused by financial bubbles.
In this model, bubbles can emerge and deflate both in cycles or directly, or they
can grow until they burst. Further, I analyze market behavior after a central
bank increases the interest rate. This can lead to new stable equilibria, but
the emergence and bursting of bubbles cannot be prevented.

text: We present strong enhancement of third harmonic generation in an amorphous
silicon metasurface consisting of elliptical nano resonators. We show that this
enhancement originates from a new type of multi-mode Fano mechanism. These ‘Super-Fano’
resonances are investigated numerically in great detail using full-wave simulations.
The theoretically predicted behavior of the metasurface is experimentally verified
by linear and nonlinear transmission spectroscopy. Moreover, quantitative nonlinear
measurements are performed, in which an absolute conversion efficiency as high
as ηmax ≈ 2.8 × 10−7 a peak power intensity of 1.2 GW cm−2 is found. Compared
to an unpatterned silicon film of the same thickness amplification factors of
up to ~900 are demonstrated. Our results pave the way to exploiting a strong Fano-type
multi-mode coupling in metasurfaces for high THG in potential applications.

text: Sparsity is a highly desired feature in deep neural networks (DNNs) since
it ensures numerical efficiency, improves the interpretability of models (due
to the smaller number of relevant features), and robustness. In machine learning
approaches based on linear models, it is well known that there exists a connecting
path between the sparsest solution in terms of the $\ell^1$ norm,i.e., zero weights
and the non-regularized solution, which is called the regularization path. Very
recently, there was a first attempt to extend the concept of regularization paths
to DNNs by means of treating the empirical loss and sparsity ($\ell^1$ norm) as
two conflicting criteria and solving the resulting multiobjective optimization
problem. However, due to the non-smoothness of the $\ell^1$ norm and the high
number of parameters, this approach is not very efficient from a computational
perspective. To overcome this limitation, we present an algorithm that allows
for the approximation of the entire Pareto front for the above-mentioned objectives
in a very efficient manner. We present numerical examples using both deterministic
and stochastic gradients. We furthermore demonstrate that knowledge of the regularization
path allows for a well-generalizing network parametrization.
