text: The computation of highly contracted electron repulsion integrals (ERIs) is
essential to achieve quantum accuracy in atomistic simulations based on quantum
mechanics. Its growing computational demands make energy efficiency a critical
concern. Recent studies demonstrate FPGAs’ superior performance and energy efficiency
for computing primitive ERIs, but the computation of highly contracted ERIs introduces
significant algorithmic complexity and new design challenges for FPGA acceleration.In
this work, we present SORCERI, the first streaming overlay acceleration for highly
contracted ERI computations on FPGAs. SORCERI introduces a novel streaming Rys
computing unit to calculate roots and weights of Rys polynomials on-chip, and
a streaming contraction unit for the contraction of primitive ERIs. This shifts
the design bottleneck from limited CPU-FPGA communication bandwidth to available
FPGA computation resources. To address practical deployment challenges for a large
number of quartet classes, we design three streaming overlays, together with an
efficient memory transpose optimization, to cover the 21 most commonly used quartet
classes in realistic atomistic simulations. To address the new computation constraints,
we use flexible calculation stages with a free-running streaming architecture
to achieve high DSP utilization and good timing closure.Experiments demonstrate
that SORCERI achieves an average 5.96x, 1.99x, and 1.16x better performance per
watt than libint on a 64-core AMD EPYC 7713 CPU, libintx on an Nvidia A40 GPU,
and SERI, the prior best-performing FPGA design for primitive ERIs. Furthermore,
SORCERI reaches a peak throughput of 44.11 GERIS (109 ERIs per second) that is
1.52x, 1.13x, and 1.93x greater than libint, libintx and SERI, respectively. SORCERI
will be released soon at https://github.com/SFU-HiAccel/SORCERI.

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."

text: "Abstract\r\n We study how
gene-environment interactions between education and genetic endowments affect
cognition in old age and use this setting to show that – even with a valid instrument
– two-stage least squares (2SLS) estimates of interaction effects can be far away
from the true effect. This is the case when treatment effects are heterogeneous
and compliance to the instrument depends on the interaction variable. We suggest
estimating marginal treatment effects to address this problem. Our estimation
results show complementarities between education and genetic predisposition in
determining later-life memory. The marginal treatment effect estimates suggest
substantially larger gene-environment interactions than the 2SLS estimates."

text: "Abstract\r\n \r\n Many
Android apps collect data from users, and the European Union’s General Data Protection
Regulation (GDPR) mandates clear disclosures of such data collection. However,
apps often use third-party code, complicating accurate disclosures. This paper
investigates how accurately current Android apps fulfill these requirements. In
this work, we present a multi-layered definition of privacy-related data to correctly
report data collection in Android apps. We further create a dataset of privacy-sensitive
data classes that may be used as input by an Android app. This dataset takes into
account data collected both through the user interface and system APIs. Based
on this, we implement a semi-automated prototype that detects and labels privacy-related
data collected by a given Android app. We manually examine the data safety sections
of 70 Android apps to observe how data collection is reported, identifying instances
of over- and under-reporting. We compare our prototype’s results with the data
safety sections of 20 apps revealing reporting discrepancies. Using the results
from two Messaging and Social Media apps (Signal and Instagram), we discuss how
app developers under-report and over-report data collection, respectively, and
identify inaccurately reported data categories. A broader study of 7,500 Android
apps reveals that apps most frequently collect data that can\r\n partially
identify\r\n users. Although system APIs consistently
collect large amounts of privacy-related data, user interfaces exhibit some more
diverse data collection patterns. A more focused study on various domains of apps
reveals that the largest fraction of apps collecting personal data belong to the
domain of\r\n Messaging and Social Media\r\n
\ . Our findings show that location is collected frequently
by apps, specially from the\r\n E-commerce and
Shopping\r\n domain. However, it is often under-reported
in app data safety sections. Our results highlight the need for greater consistency
in privacy-aware app development and reporting practices.\r\n "

text: "ABSTRACT\r\n \r\n Electrification
offers a promising route to reduce CO\r\n 2\r\n
\ emissions in the chemical sector. In distillation, heat pump
integration such as mechanical vapor recompression (MVR) can replace fossil‐based
utilities, but column parameters like pressure drop should be accurately considered
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
vacuum distillation sequence is evaluated for utility demand, CO\r\n 2\r\n
\ emissions, and economic feasibility under varying pressure
drops, preheating configurations, and cost and emission scenarios.\r\n "

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: Carbon fiber-reinforced plastics (CFRPs) have become increasingly
significant in recent decades due to their remarkable mechanical properties and
lightweight nature. This study aims to advance the understanding and simulation
of CFRP behavior through the development of a hyperelastic-plastic-damage homogenization
method combined with mean-field theory. The material responses of both the fiber
and matrix are modeled using strain energy functions that account for damage evolution,
while a complete linearization of the homogenization process is derived to ensure
the consistent implementation of the Newton–Raphson iteration scheme in large
deformation simulations. The innovative aspect of this work lies in the constitutive
linearization for the hyperelastic-plastic-damage formulation within a mean-field
homogenization framework, providing an efficient Newton algorithm for modeling
the nonlinear behavior of CFRP. A failure criterion for the hyperelastic model
of fibers is introduced, along with a damage saturation variable in rate form
for the matrix, effectively capturing damage evolution. Through discrete formulations
for the homogenization, the proposed model’s capability is demonstrated via three
numerical examples and validated against experimental investigations, proving
its effectiveness and reliability in simulating CFRP damage.
