text: In this paper we present a new system architecture for software-defined radio
/ radar with optical signal distribution. The proposed architecture allows to
transmit the optical carrier and an arbitrary IQ signal on the same fiber from
a base station to wireless transmitters using a single laser. Furthermore, we
can reuse parts, and under special conditions, also the complete optical output
of the base station for the IQ return path from the wireless receiver frontends
to the base station. Avoiding multiple lasers and fibers for the distribution
of the carrier and arbitrary signal from the base station to the frontend, and
avoiding the laser diode for the IQ return path from receiver frontends to the
base station reduces the hardware effort significantly. Finally, the system architecture
allows to integrate all components of the optoelectronic wireless frontend in
a single chip using silicon photonics technology.

text: "This paper presents a method to model monolithically integrated photonic
radar transceiver (TRX) with optical local oscillator (LO) distribution in silicon
germanium (SiGe) electronic photonic integrated circuits (EPICs). The model proposed
approximates the behavior of the nonlinear scattering (S)-parameters and noise
figure of each building block of the TRX chipset by Laplace polynomials and hyperbolic
tangent functions. The modular approach of the model allows to optimize hardware
components with respect to the entire TRX system, and fault identification with
reduced computational effort.\r\nThe proposed method is validated using the first
monolithically integrated photonic radar transceiver chipset and shows excellent
agreement with the post layout simulation results and, including the photodiode
(PD) bandwidth (BW) degradation, also with the measurements.\r\n"

text: We present a method for the generation of higher-order tetrahedral
meshes. In contrast to previous methods, the curved tetrahedral elements are guaranteed
to be free of degeneracies and inversions while conforming exactly to prescribed
piecewise polynomial surfaces, such as domain boundaries or material interfaces.
Arbitrary polynomial order is supported. Algorithmically, the polynomial input
surfaces are first covered by a single layer of carefully constructed curved elements
using a recursive refinement procedure that provably avoids degeneracies and inversions.
These tetrahedral elements are designed such that the remaining space is bounded
piecewise linearly. In this way, our method effectively reduces the curved meshing
problem to the classical problem of linear mesh generation (for the remaining
space).

text: "\r\n Volumetric mapping is a ubiquitous and difficult
problem in Geometry Processing and has been the subject of research in numerous
and various directions. While several methods show encouraging results, the field
still lacks a general approach with guarantees regarding map bijectivity. Through
this work, we aim at opening the door to a new family of methods by providing
a novel framework based on the concept of\r\n progressive
expansion.\r\n Starting from an initial map of a tetrahedral
mesh whose image may contain degeneracies but no inversions, we incrementally
adjust vertex images to expand degenerate elements. By restricting movement to
so-called\r\n expansion cones\r\n ,
it is done in such a way that the number of degenerate elements decreases in a
strictly monotonic manner, without ever introducing any inversion. Adaptive local
refinement of the mesh is performed to facilitate this process. We describe a
prototype algorithm in the realm of this framework for the computation of maps
from ball-topology tetrahedral meshes to convex or star-shaped domains. This algorithm
is evaluated and compared to state-of-the-art methods, demonstrating its benefits
in terms of bijectivity. We also discuss the associated cost in terms of sometimes
significant mesh refinement to obtain the necessary degrees of freedom required
for establishing a valid mapping. Our conclusions include that while this algorithm
is only of limited immediate practical utility due to efficiency concerns, the
general framework has the potential to inspire a range of novel methods improving
on the efficiency aspect.\r\n "

text: We present a set of operators to perform modifications, in particular
collapses and splits, in volumetric cell complexes which are discretely embedded
in a background mesh. Topological integrity and geometric embedding validity are
carefully maintained. We apply these operators strategically to volumetric block
decompositions, so-called T-meshes or base complexes, in the context of hexahedral
mesh generation. This allows circumventing the expensive and unreliable global
volumetric remapping step in the versatile meshing pipeline based on 3D integer-grid
maps. In essence, we reduce this step to simpler local cube mapping problems,
for which reliable solutions are available. As a consequence, the robustness of
the mesh generation process is increased, especially when targeting coarse or
block-structured hexahedral meshes. We furthermore extend this pipeline to support
feature alignment constraints, and systematically respect these throughout, enabling
the generation of meshes that align to points, curves, and surfaces of special
interest, whether on the boundary or in the interior of the domain.

text: A method is presented to compute volumetric maps and parametrizations
of objects over 3D domains. As a key feature, continuity and bijectivity are ensured
by construction. Arbitrary objects of ball topology, represented as tetrahedral
meshes, are supported. Arbitrary convex as well as star-shaped domains are supported.
Full control over the boundary mapping is provided. The method is based on the
technique of simplicial foliations, generalized to a broader class of domain shapes
and applied adaptively in a novel localized manner. This increases flexibility
as well as efficiency over the state of the art, while maintaining reliability
in guaranteeing map bijectivity.

text: AbstractWe describe HalfedgeCNN, a collection
of modules to build neural networks that operate on triangle meshes. Taking inspiration
from the (edge‐based) MeshCNN, convolution, pooling, and unpooling layers are
consistently defined on the basis of halfedges of the mesh, pairs of oppositely
oriented virtual instances of each edge. This provides benefits over alternative
definitions on the basis of vertices, edges, or faces. Additional interface layers
enable support for feature data associated with such mesh entities in input and
output as well. Due to being defined natively on mesh entities and their neighborhoods,
lossy resampling or interpolation techniques (to enable the application of operators
adopted from image domains) do not need to be employed. The operators have various
degrees of freedom that can be exploited to adapt to application‐specific needs.

text: The security of Industrial Control Systems is relevant both for reliable production
system operations and for high-quality throughput in terms of manufactured products.
Security measures are designed, operated and maintained by different roles along
product and production system lifecycles. Defense-in-Depth as a paradigm builds
upon the assumption that breaches are unavoidable. The paper at hand provides
an analysis of roles, corresponding Human Factors and their relevance for data
theft and sabotage attacks. The resulting taxonomy is reflected by an example
related to Additive Manufacturing. The results assist in both designing and redesigning
Industrial Control System as part of an entire production system so that Defense-in-Depth
with regard to Human Factors is built in by design.

text: '3D printing is a well-established technology with rapidly increasing usage
scenarios both in the industry and consumer context. The growing popularity of
3D printing has also attracted security researchers, who have analyzed possibilities
for weakening 3D models or stealing intellectual property from 3D models. We extend
these important aspects and provide the first comprehensive security analysis
of 3D printing data formats. We performed our systematic study on the example
of the 3D Manufacturing Format (3MF), which offers a large variety of features
that could lead to critical attacks. Based on 3MF’s features, we systematized
three attack goals: Data Exfiltration (dex), Denial of Service, and UI Spoofing
(uis). We achieve these goals by exploiting the complexity of 3MF, which is based
on the Open Packaging Conventions (OPC) format and uses XML to define 3D models.
In total, our analysis led to 352 tests. To create and run these tests automatically,
we implemented an open-source tool named 3MF Analyzer (tool), which helped us
evaluate 20 applications.'

text: 'In XAI it is important to consider that, in contrast to explanations for
professional audiences, one cannot assume common expertise when explaining for
laypeople. But such explanations between humans vary greatly, making it difficult
to research commonalities across explanations. We used the dual nature theory,
a techno-philosophical approach, to cope with these challenges. According to it,
one can explain, for example, an XAI''s decision by addressing its dual nature:
by focusing on the Architecture (e.g., the logic of its algorithms) or the Relevance
(e.g., the severity of a decision, the implications of a recommendation). We investigated
20 game explanations using the theory as an analytical framework. We elaborate
how we used the theory to quickly structure and compare explanations of technological
artifacts. We supplemented results from analyzing the explanation contents with
results from a video recall to explore how explainers justified their explanation.
We found that explainers were focusing on the physical aspects of the game first
(Architecture) and only later on aspects of the Relevance. Reasoning in the video
recalls indicated that EX regarded the focus on the Architecture as important
for structuring the explanation initially by explaining the basic components before
focusing on more complex, intangible aspects. Shifting between addressing the
two sides was justified by explanation goals, emerging misunderstandings, and
the knowledge needs of the explainee. We discovered several commonalities that
inspire future research questions which, if further generalizable, provide first
ideas for the construction of synthetic explanations.'

- lang: eng
text: "AbstractThis note is concerned with two
families of operators related to the fractional Laplacian, the first arising from
the Caffarelli-Silvestre extension problem and the second from the fractional
heat equation. They both include the Poisson semigroup. We show that on a complete,
connected, and non-compact Riemannian manifold of non-negative Ricci curvature,
in both cases, the solution with $$L^1$$\r\n \r\n
\ L\r\n 1\r\n
\ \r\n
initial data behaves asymptotically as the mass times the fundamental solution.
Similar long-time convergence results remain valid on more general manifolds satisfying
the Li-Yau two-sided estimate of the heat kernel. The situation changes drastically
on hyperbolic space, and more generally on rank one non-compact symmetric spaces:
we show that for the Poisson semigroup, the convergence to the Poisson kernel
fails -but remains true under the additional assumption of radial initial data."
