text: "The state of the art shows that PBF-LB/M offers great potential for pressure-loaded
parts, with significant weight reductions and simultaneous optimization of flow
resistance. This study is aimed at applying existing calculation methods for pressure-loaded
parts to additively manufactured pipe structures, considering the two materials
EN AC-43000 (3.2381, AlSi10Mg) and AISI 316L (1.4404, X2CrNiMo17-12-2). For this
purpose, systematic tensile tests are carried out for both materials. In addition,
a statistical evaluation is performed to determine the design-relevant strength
characteristics with a survival probability Ps of 97.5 % for both materials in
the as-built and heat-treated condition.\r\nPipe specimens are manufactured, half
of which are heat treated, geometrically measured and then subjected to a burst
pressure test to experimentally determine the failure-critical internal pressure.
These results are compared with calculated burst pressures. The calculations are
based on the application-relevant methods identified in this study, considering
the strength values determined for the respective material condition. This comparison
is used to assess the suitability of the calculation methods for additively manufactured
pipe structures, based on the materials investigated."

text: Cobalt spinel (Co3O4) catalysts are widely studied in scope of the electrocatalytic
oxygen evolution reaction (OER), yet the role of interfacial structural transformation
under anodic bias remains under debate. Here, we employ an operando approach,
combining a fast electrochemical quartz crystal microbalance with dissipation
monitoring (EQCM-D), electrochemical impedance spectroscopy (EIS), and Raman spectroscopy
to investigate interfacial transformations of Co3O4 nanoparticle electrodes in
alkaline electrolyte. We identify two distinct regimes during the anodic sweep
prior to the macroscopic OER onset. At lower potentials, the catalyst interface
remains mechanically rigid while reversibly associating several OH−/H2O species
per oxidized cobalt site. At higher potentials, pronounced softening of the interface
occurs alongside further uptake of electrolyte species. This indicates amorphization
and a ‘swelling process’ beyond simple adsorption. Notably, an electrochemical
conditioning treatment can suppress mass and compliance hysteresis without affecting
OER activity, suggesting that most incorporated electrolyte species do not participate
in the OER. EIS further reveals that OER intermediates form well below the apparent
OER onset potential. These results advance our mechanistic understanding of interfacial
transformations in cobalt-based OER catalysts and establish EQCM-D as a sensitive
operando technique for probing electrocatalyst transformations.

text: "Translated from German, The Handbook of Qualitative and Quantitative Content
Analysis is a comprehensive handbook which offers an application-orientated introduction
to qualitative and quantitative content analysis methods.\r\n\r\nThe book provides
explanations for beginners from bachelor level onwards on how to select an appropriate
qualitative or quantitative content analysis method and how to use the chosen
method(s) depending on research interest and amount of data. Part 1 defines the
basics of qualitative and quantitative content analysis and empirical research,
including research quality conventions and how to do interpretation; Part 2 is
a practical guide to classical qualitative content analysis and semi-automated
quantitative content analysis; and Part 3 introduces Python alongside automated
techniques such as correspondence analysis, semantic network analysis, sentiment
analysis, and topic modelling using generative and deep learning algorithms. Each
of these sections are enriched with extensive examples and cover a range of software
applications, including AntConc, MAXQDA, Python, and VosViewer.\r\n\r\nThis is
the ideal resource for anyone interested in content analysis research methods
across the social sciences, humanities, and data sciences."

text: The Banzhaf power index can be used to quantify the explanatory power of single
conditions in a configurational analysis that aims at identifying whether combinations
of conditions are sufficient for an outcome. The latter method is an integral
part of the Qualitative Comparative Analysis (QCA) approach. It is widely used
in the literature, e.g., in the field of International Management. Haake and Schneider
(2023) give a rigorous description of the connection between the empirical and
game theoretic modeling. To justify that the Banzhaf index is an appropriate tool
to measure the influence of a condition, this paper discusses a novel axiomatization
of the Banzhaf index that uses axioms that are directly linked to the QCA methodology.
As a side result, we demonstrate that in our model the Banzhaf index can be reinterpreted
as an average of Shapley-Shubik indices.

text: Proton exchange membranes (PEMs) are essential for fuel cells, yet conventional
materials like Nafion suffer from humidity dependence and limited thermal stability.
This study introduces sulfonated phenylene-bridged periodic mesoporous organosilicas
(PMOs) as promising inorganic–organic hybrid PEMs, synthesized via surfactant-templating
with varying alkyl chain lengths for different mesopore sizes. Post-synthetic
functionalization involves nitration of phenylene moieties, reduction to amines,
and ring-opening of propane or butane sultones to graft sulfonic acid groups via
flexible spacers, achieving homogeneous distribution along pore walls. Post-functionalization
is confirmed by powder X-ray diffraction (PXRD), revealing preserved 2D hexagonal
p6mm ordering and phenylene stacking. N2 physisorption shows type IV isotherms
with reduced pore volumes and pore sizes. 1H NMR is used to quantify functionalization
degrees. Impedance spectroscopy on pressed pellets demonstrates proton conductivities
up to 2 × 10−3 S cm−1 at 30 °C and 90% RH, depending on the functionalization
degree, confirming sulfonic acid-mediated conduction.

text: "When do two irreducible polynomials with integer coefficients\r\n define
the same number field? One can define an action of\r\n $\\mathrm{GL}_2 \\times
\\mathrm{GL}_1$ on the space of polynomials of degree $n$ so that for any two\r\n
\ polynomials $f$ and $g$ in the same orbit, the roots of $f$ may be expressed\r\n
\ as rational linear transformations of the roots of $g$; thus, they generate\r\n
\ the same field. In this article, we show that almost all polynomials of\r\n
\ degree $n$ with size at most $X$ can only define the same number field as\r\n
\ another polynomial of degree $n$ with size at most $X$ if they lie in the\r\n
\ same orbit for this group action. (Here we measure the size of polynomials by\r\n
\ the greatest absolute value of their coefficients.)\r\n This improves on work

text: This article examines the liquidity effects of a wealth tax on residential
rental real estate. Using data from a real estate corporation, we simulate the
effects of a wealth tax on cash flows from the rental operations. The level of
detail of the data enables us to conduct analyses at the annual, regional and
year of construction level. A comparison with real estate data from other sources
supports external validity. The results of the simulation show that the introduction
of a wealth tax can significantly reduce the cash flow from rental operations
and lead to liquidity problems. On average over all observations, a wealth tax
rate of 2% leads to a negative cash flow after all costs. In general, this finding
implies that growth-oriented real estate is more affected by a wealth tax in terms
of liquidity than rental yield-oriented real estate. Particularly in large cities
with high market values but relatively low rents, the liquidity effects can be
more than three times as high as in rural or industrial regions – potentially
leading to a relative loss of investment attractiveness. As a wealth tax is decoupled
from rental income, the tax burden is very sensitive to market developments, including
the interest rate environment. As a result, investments in residential rental
real estate are exposed to additional uncertainty. This additional tax uncertainty
might impair the willingness to invest and should therefore be taken into account
in political discussions on the reintroduction of a wealth tax.

text: "Abstract\r\n We study the
effect of education on health (hospital stays, number of diagnosed conditions,
poor or bad self-rated health, and body mass index) over the life cycle, using
German compulsory schooling reforms as a source of exogenous variation. Our results
show clear correlations between educational attainment and better health across
all age groups (30 to 74). However, we do not find causal relationships between
additional schooling and health or health care utilization, neither earlier nor
later in life. A simulated ex-post power analysis shows that this is not due to
a lack of statistical power. One reason for the absence of effects may be that
the studied compulsory schooling reforms succeeded in raising the educational
attainment of the target group - individuals at the lowest educational margin
- but did not lead to healthier employment opportunities."

integration such as mechanical vapor recompression (MVR) can replace fossil‐based

when assessing integration potential. This work discusses the effect of feed preheating
and column pressure drop on MVR integration potential. The two binary separation
tasks, methanol–water and benzene–toluene, are analyzed to identify energetically
optimal preheater and MVR design. In addition, MVR integration in a bioethanol

text: Overcoming the slow kinetics of the oxygen evolution reaction at the anode
is a key challenge for the production of hydrogen via electrolysis. This reaction
operates at very positive potentials, where the electrocatalyst is exposed to
highly oxidative conditions and prone to potential-dependent transformation of
the near-surface region. While substantial evidence for such surface restructuring
exists, its extent and relevance for the catalyst’s activity are unclear. We address
this topic for the case of Co3O4, one of the best-known electrocatalysts exhibiting
surface restructuring, by studies of epitaxial (111)-ordered electrodeposited
films with combined operando X-ray surface diffraction and absorption spectroscopy,
electrochemical impedance spectroscopy, and electrochemical measurements on rotating
disk electrodes. Comparison of the as-prepared and annealed state of the same
samples, which both are stable even under long-term oxygen evolution conditions,
provides clear insight into the role of surface defects. Our results show that
defect-free annealed Co3O4(111) surfaces are structurally stable over a wide potential
range and hydroxylate via adsorption at surface oxygen and Co sites. Potential-induced
surface restructuring of the Co3O4 lattice occurs only in the presence of surface
defects, leading to the formation of the well-known nanometer-thick oxyhydroxide
skin layer. The presence of this skin layer promotes oxygen evolution at low overpotentials
but results in higher Tafel slopes. As a result, highly ordered Co3O4(111) surfaces
are more active at high current densities than defective Co3O4 surfaces that undergo
surface restructuring. These results highlight that strategies for catalyst surface
defect engineering need to be application-oriented.

text: "We study a block mean-field Ising model with $N$ spins split into $s_N$ blocks,
with Curie-Weiss interaction within blocks and nearest-neighbor coupling between
blocks. While previous models deal with the block magnetization for a fixed number
of blocks, we study the the simultaneous limit $N\\to\\infty$ and $s_N\\to\\infty$.
The model interpolates between Curie-Weiss model for $s_N=1$, multi-species mean
field for fixed $s_N=s$, and the 1D Ising model for each spin in its own block
at $s_N=N$.\r\n Under mild growth conditions on $s_N$, we prove a law of large
numbers and a multivariate CLT with covariance given by the lattice Green's function.
For instance, the high temperature CLT essentially covers the optimal range up
to $s_N=o(N/(\\log N)^c)$ and the low temperature regime is new even for fixed
number of blocks $s > 2$. In addition to the standard competition between entropy
and energy, a new obstacle in the proofs is a curse of dimensionality as $s_N
\\to \\infty$."

text: "Durch eine stabile Wirtschaftslage, routinierte Strukturen in der Ernährungswirtschaft
und\r\ndurch ein vergleichsweise geringes Preisniveau ist es für Verbraucher*innen
selbstverständ-\r\nlich, dass Lebensmittel nahezu jederzeit verfügbar sind und
gekauft werden können [1].\r\nEreignisse in jüngerer Vergangenheit, z. B. Krieg
in der Ukraine (2022), Naturkatastrophen\r\nwie das Hochwasser an der Ahr (2022)
oder die Corona-Pandemie (2020), haben jedoch\r\ngezeigt, dass diese Infrastruktur
unserer Gesellschaft anfällig ist [2] und die Versorgungs-\r\nketten aus dem Gleichgewicht
bringen können [3]. Zwar zeigen Untersuchungen, dass sich\r\ndie Bevölkerung seit
der Corona-Pandemie verstärkt mit der Bevorratung von Lebensmitteln\r\nauseinandersetzt,
allerdings gibt es immer noch eine deutliche Diskrepanz zwischen den\r\nstaatlichen
Empfehlungen und der tatsächlichen Umsetzung durch die Bevölkerung [1, 3, 4].\r\nVor
diesem Hintergrund zielt der Artikel darauf ab, den Unterschied zwischen staatlicher
und\r\nprivater Ernährungsvorsorge zu erklären, Anforderungen ausgewählter Lebensmittelgruppen\r\nzur
optimalen Lagerung zu beschreiben sowie eine praktische Anleitung zur sinnvollen\r\nVorratshaltung
von Lebensmitteln für den Notfall zu geben."

text: Continuous flow catalysis utilizing gel-bound organocatalysts within a microfluidic
reactor represents a compelling strategy in the realm of organic synthesis. In
this study, a quinuclidine-based catalytic monomer (QMA) was synthesized to create
polymer gel dots through the process of photopolymerization that serve as a support
for the catalyst. The resulting gel-bound organocatalysts were assembled within
a continuous microfluidic reactor to facilitate the Baylis–Hillman reaction between
various aldehydes and acrylonitrile at a temperature of 50 °C. The conversion
of the product was assessed using 1H NMR spectroscopy as an offline analytical
method over a duration of 8 h. The findings indicated that highly reactive aldehydes
achieved conversion rates exceeding 90%, in contrast to their less reactive counterparts.
Furthermore, these results were juxtaposed with previously published data derived
from alternative synthetic methodologies, revealing that the continuous microfluidic
reactions employing integrated organocatalysts within polymer networks exhibited
significantly higher conversions with reduced reaction times (8 h) at the same
temperature (50 °C). Additionally, the influence of different geometries (round,
triangular, and square) of the gel dots on catalytic activity was investigated,
with round and square gel dots demonstrating slightly superior performance compared
with triangular gel dots, attributed to their increased surface area. Moreover,
an extended reaction period of 6 days was conducted using 4-bromobenzaldehyde
and acrylonitrile, resulting in a conversion rate exceeding 70%, which remained
stable for 5 days before experiencing a slight decline due to product accumulation
on the gel dots.
