text: Many real-world datasets, such as citation networks, social networks, and
molecular structures, are naturally represented as heterogeneous graphs, where
nodes belong to different types and have additional features. For example, in
a citation network, nodes representing "Paper" or "Author" may include attributes
like keywords or affiliations. A critical machine learning task on these graphs
is node classification, which is useful for applications such as fake news detection,
corporate risk assessment, and molecular property prediction. Although Heterogeneous
Graph Neural Networks (HGNNs) perform well in these contexts, their predictions
remain opaque. Existing post-hoc explanation methods lack support for actual node
features beyond one-hot encoding of node type and often fail to generate realistic,
faithful explanations. To address these gaps, we propose DiGNNExplainer, a model-level
explanation approach that synthesizes heterogeneous graphs with realistic node
features via discrete denoising diffusion. In particular, we generate realistic
discrete features (e.g., bag-of-words features) using diffusion models within
a discrete space, whereas previous approaches are limited to continuous spaces.
We evaluate our approach on multiple datasets and show that DiGNNExplainer produces
explanations that are realistic and faithful to the model's decision-making, outperforming
state-of-the-art methods.

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: "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: "Given a real semisimple connected Lie group $G$ and a discrete torsion-free\r\nsubgroup
$\\Gamma < G$ we prove a precise connection between growth rates of the\r\ngroup
$\\Gamma$, polyhedral bounds on the joint spectrum of the ring of\r\ninvariant
differential operators, and the decay of matrix coefficients. In\r\nparticular,
this allows us to completely characterize temperedness of\r\n$L^2(\\Gamma\\backslash
G)$ in this general setting."

text: The complexity and interconnectivity of modern automotive systems
are rapidly increasing, particularly with the rise of distributed and cooperative
driving functions. These developments increase exposure to a range of disruptions,
from technical failures to cyberattacks, and demand a shift towards resilience-by-design.
This study addresses the early integration of resilience into the automotive design
process by proposing a structured method for identifying gaps and eliciting resilience
requirements. Building upon the concept of resilience scenarios, the approach
extends traditional hazard and threat analyses as defined in ISO 26262, ISO 21448
and ISO/SAE 21434. Using a structured, graph-based modeling method, these scenarios
enable the anticipation of functional degradation and its impact on driving scenarios.
The methodology helps developers to specify resilience requirements at an early
stage, enabling the integration of resilience properties throughout the system
lifecycle. Its practical applicability is demonstrated through an example in the
field of automotive cybersecurity. This study advances the field of resilience
engineering by providing a concrete approach for operationalizing resilience within
automotive systems engineering.

text: "Abstract\r\n We show how
the Fourier transform for distributional sections of vector bundles over symmetric
spaces of non‐compact type can be used for questions of solvability of systems
of invariant differential equations in analogy to Hörmander's proof of the Ehrenpreis–Malgrange
theorem. We get complete solvability for the hyperbolic plane and partial results
for products and the hyperbolic 3‐space ."
