text: PurposeThe
purpose of this paper is to revisit the disastrous DaimlerChrysler AG takeover
episode from 1998 to 2007 in order to arrive at a more comprehensive explanation
of this and other merger and takeover failures based on institutional theory.Design/methodology/approachThe
case study is based on various secondary sources of information and on the insights
that one of the authors gained from working for 14 years in various positions
for Daimler-Benz and DaimlerChrysler.FindingsDaimlerChrysler
failed because top management made mistakes in trying to globalize the company.
They were unable to realize possible synergies between the two companies, which
brought complementary resources into the merger. Furthermore, they did not account
for the institutional embeddedness of strategies when they adopted lean production
globally, diffused the production system developed in Germany to other parts of
the world and tried to implement a global stock enlisted in New York and Frankfurt.
The underlying theoretical framework is relevant for other merger and acquisition
cases. It features institutional embeddedness, path dependency and institutional
arbitrage.Originality/valueThe
paper develops an institutional perspective on DaimlerChrysler and on cross-border
merger and acquisition failure more generally. The perspective is organized around
the varieties-of-capitalism approach. This contribution is important because there
is increasing dissatisfaction with the dominant explanation of cross-border merger
and acquisition failure, which is based on the allegedly failed management of
culture “clashes.”

text: "The Quantum Singular Value Transformation (QSVT) is a recent technique that\r\ngives
a unified framework to describe most quantum algorithms discovered so\r\nfar,
and may lead to the development of novel quantum algorithms. In this paper\r\nwe
investigate the hardness of classically simulating the QSVT. A recent result\r\nby
Chia, Gily\\'en, Li, Lin, Tang and Wang (STOC 2020) showed that the QSVT can\r\nbe
efficiently \"dequantized\" for low-rank matrices, and discussed its\r\nimplication
to quantum machine learning. In this work, motivated by\r\nestablishing the superiority
of quantum algorithms for quantum chemistry and\r\nmaking progress on the quantum
PCP conjecture, we focus on the other main class\r\nof matrices considered in
applications of the QSVT, sparse matrices.\r\n We first show how to efficiently
\"dequantize\", with arbitrarily small\r\nconstant precision, the QSVT associated
with a low-degree polynomial. We apply\r\nthis technique to design classical algorithms
that estimate, with constant\r\nprecision, the singular values of a sparse matrix.
We show in particular that a\r\ncentral computational problem considered by quantum
algorithms for quantum\r\nchemistry (estimating the ground state energy of a local
Hamiltonian when\r\ngiven, as an additional input, a state sufficiently close
to the ground state)\r\ncan be solved efficiently with constant precision on a
classical computer. As a\r\ncomplementary result, we prove that with inverse-polynomial
precision, the same\r\nproblem becomes BQP-complete. This gives theoretical evidence
for the\r\nsuperiority of quantum algorithms for chemistry, and strongly suggests
that\r\nsaid superiority stems from the improved precision achievable in the quantum\r\nsetting.
We also discuss how this dequantization technique may help make\r\nprogress on
the central quantum PCP conjecture."

text: Recent analyses by polarization resolved second-harmonic (SH) microscopy have
demonstrated that ferroelectric (FE) domain walls (DWs) can possess non-Ising
wall characteristics and topological nature. These analyses rely on locally analyzing
the properties, directionality, and magnitude of the second-order nonlinear tensor.
However, when inspecting FE DWs with SH microscopy, a manifold of different effects
may contribute to the observed signal difference between domains and DWs, i.e.,
far-field interference, Čerenkov-type phase-matching (CSHG), and changes in the
aforementioned local nonlinear optical properties. They all might be present at
the same time and, therefore, require careful interpretation and separation. In
this work, we demonstrate how the particularly strong Čerenkov-type contrast can
selectively be blocked using dark- and bright-field SH microscopy. Based on this
approach, we show that other contrast mechanisms emerge that were previously overlayed
by CSHG but can now be readily selected through the appropriate experimental geometry.
Using the methods presented, we show that the strength of the CSHG contrast compared
to the other mechanisms is approximately 22 times higher. This work lays the foundation
for the in-depth analysis of FE DW topologies by SH microscopy.

text: Spontaneous Raman spectroscopy (SR) is a versatile method for analysis and
visualization of ferroelectric crystal structures, including domain walls. Nevertheless,
the necessary acquisition time makes SR impractical for in situ analysis and large
scale imaging. In this work, we introduce broadband coherent anti-Stokes Raman
spectroscopy (B-CARS) as a high-speed alternative to conventional Raman techniques
and demonstrate its benefits for ferroelectric domain wall analysis. Using the
example of poled lithium niobate, we compare the spectral output of both techniques
in terms of domain wall signatures and imaging capabilities. We extract the Raman-like
resonant part of the coherent anti-Stokes signal via a Kramers–Kronig-based phase
retrieval algorithm and compare the raw and phase-retrieved signals to SR characteristics.
Finally, we propose a mechanism for the observed domain wall signal strength that
resembles a Čerenkov-like behavior, in close analogy to domain wall signatures
obtained by second-harmonic generation imaging. We, thus, lay here the foundations
for future investigations on other poled ferroelectric crystals using B-CARS.

text: Conductive domain walls (DWs) in insulating ferroelectrics have recently attracted
considerable attention due to their unique topological, optical, and electronic
properties, and offer potential applications such as in memory devices or rewritable
circuitry. The electronic properties of DWs can be tuned by the application of
strain, hence controlling the charge carrier density at DWs. In this paper, we
study the influence of uniaxial stress on the conductivity of DWs in the bulk
single crystal lithium niobate (LiNbO3). Using conductive atomic force microscopy,
we observe a large asymmetry in the conductivity of DWs, where only negatively
screened walls, so called head-to-head DWs, are becoming increasingly conductive,
while positively screened, tail-to-tails DWs, show a decrease in conductivity.
This asymmetry of DW conductivity agrees with our theoretical model based on the
piezoelectric effect. In addition, we observed that the current in the DW increases
up to an order of magnitude for smaller compressive stresses of 100 MPa. This
response of DWs remained intact for multiple stress cycles over two months, opening
a path for future applications.

text: Strongly charged head-to-head domain walls that are purposely engineered along
the [110] crystallographic orientation into ferroelectric BaTiO3 single crystals
have been proposed as intrinsically nanoscaled two-dimensional electron gases
(2DEGs) because of their significant conductivity. Here, we quantify these 2DEG
properties through dedicated Hall transport measurements in van der Pauw 4-point
geometry, finding the electron mobility to reach around 400 cm2 (V s)^{−1}, while
the two-dimensional charge density amounts to 7 × 103 cm^{–2}. We underline the
necessity to take into account the thermal and geometrical misalignment offset
voltages by evaluating the Hall resistance under magnetic field sweeps; otherwise,
errors of several hundred percent in the derived transport parameters can occur.

text: Thin-film materials from μm thickness down to single-atomic-layered 2D materials
play a central role in many novel electronic and optical applications. Coherent,
nonlinear optical (NLO) μ-spectroscopy offers insight into the local thickness,
stacking order, symmetry, or electronic and vibrational properties. Thin films
and 2D materials are usually supported on multi-layered substrates leading to
(multi-)reflections, interference, or phase jumps at interfaces during μ-spectroscopy,
which all can make the interpretation of experiments particularly challenging.
The disentanglement of the influence parameters can be achieved via rigorous theoretical
analysis. In this work, we compare two self-developed modeling approaches, a semi-analytical
and a fully vectorial model, to experiments carried out in thin-film geometry
for two archetypal NLO processes, second-harmonic and third-harmonic generation.
In particular, we demonstrate that thin-film interference and phase matching do
heavily influence the signal strength. Furthermore, we work out key differences
between three and four photon processes, such as the role of the Gouy-phase shift
and the focal position. Last, we can show that a relatively simple semi-analytical
model, despite its limitations, is able to accurately describe experiments at
a significantly lower computational cost as compared to a full vectorial modeling.
This study lays the groundwork for performing quantitative NLO μ-spectroscopy
on thin films and 2D materials, as it identifies and quantifies the impact of
the corresponding sample and setup parameters on the NLO signal, in order to distinguish
them from genuine material properties.<

text: AbstractPure samples of colorless, air‐stable
Ba(BO2OH) crystals were obtained from Ba(NO3)2
and H3BO3 under the ultra‐alkaline conditions
of a KOH hydroflux at about 250 °C. The product formation depends on the water‐base
molar ratio and the molar ratio of the starting materials. B(OH)3
acts as a proton donor (Brønsted acid) rather than a hydroxide acceptor (Lewis
acid). Ba(BO2OH) crystallizes in the non‐centrosymmetric
orthorhombic space group P212121.
Hydrogen bonds connect the almost planar (BO2OH)2−
anions, which are isostructural to HCO3−,
into a syndiotactic chain. IR and Raman spectroscopy confirm the presence of hydroxide
groups, which are involved in weak hydrogen bonds. Upon heating in air to about
450 °C, Ba(BO2OH) dehydrates to Ba2B2O5.
Moreover, the non‐centrosymmetric structure of Ba(BO2OH)
crystals was verified with power‐dependent confocal Second Harmonic Generation
(SHG) microscopy indicating large conversion efficiencies in ambient atmosphere.

text: Second harmonic (SH) microscopy represents a powerful tool for the investigation
of crystalline systems, such as ferroelectrics and their domain walls (DWs). Under
the condition of normal dispersion, i.e., the refractive index at the SH wavelength
is larger as compared to the refractive index at the fundamental wavelength, n(2ω)>n(ω),
bulk crystals will generate no SH signal. Should the bulk, however, contain DWs,
an appreciable SH signal will still be detectable at the location of DWs stemming
from the Čerenkov mechanism. In this work, we demonstrate both how SH signals
are generated in bulk media and how the Čerenkov mechanism can be inhibited by
using anomalous dispersion, i.e., n(ω)Journal of Applied
