text: We study the statistics of the number of real eigenvalues in the elliptic
deformation of the real Ginibre ensemble. As the matrix dimension grows, the law
of large numbers and the central limit theorem for the number of real eigenvalues
are well understood, but the probabilities of rare events remain largely unexplored.
Large deviation type results have been obtained only in extreme cases, when either
a vanishingly small proportion of eigenvalues are real or almost all eigenvalues
are real. Here, in both the strong and weak asymmetry regimes, we derive the probabilities
of rare events in the moderate-to-large deviation regime, thereby providing a
natural connection between the previously known regime of Gaussian fluctuations
and the large deviation regime. Our results are new even for the classical real
Ginibre ensemble.

text: 'We study the evolution of zeros of high polynomial powers under the heat
flow. For any fixed polynomial $P(z)$, we prove that the empirical zero distribution
of its heat-evolved $n$-th power converges to a distribution on the complex plane
as $n$ tends to infinity. We describe this limit distribution $μ_t$ as a function
of the time parameter $t$ of the heat evolution: For small time, zeros start to
spread out in approximately semicircular distributions, then intricate curves
start to form and merge, until for large time, the zero distribution approaches
a widespread semicircle law through the initial center of mass. The Stieltjes
transform of the limit distribution $μ_t$ satisfies a self-consistent equation
and a Burgers'' equation. The present paper deals with general complex-rooted
polynomials for which, in contrast to the real-rooted case, no free-probabilistic
representation for $μ_t$ is available.'

text: "\r\n Lateral ankle sprain (LAS) is the most common
traumatic injury, with a high recurrence rate and chronic ankle instability (CAI)
developing in ∼40% of cases. LAS leads to patho-mechanical, sensory-perceptual
and motor-behavioral deficits. Poor management of the return-to-sport (RTS) is
now considered a major cause of re-injury and development of CAI, particularly
due to the lack of validated tests and the failure of existing ones to account
for those central deficits. The first part of this topic aimed to clarify concepts
of cognitive constructs and sensory reweighting and their association with CAI.
We also aimed to identify objective RTS criteria and discuss their limits regarding
their ability to encompass central impairments. Motor-cognitive deficits have
been identified using computerized cognitive tasks and dual-task paradigms. More
specifically, deficits in visual memory, processing speed or inhibitory control
and attentional resource allocation have demonstrated reduced performance in CAI
populations. In addition, altered sensory reweighting process towards visual input
has also been observed. While objective criteria are crucial to prevent re-injury,
current evaluations remain largely subjective and central impairments are unaccounted
for in conventional RTS testing. The Ankle-GO\r\n TM\r\n
\ score was recently developed to guide clinicians in decision
making process. To date, it is the first validated score that could help to identify
patients who will RTS at the same level, those at risk of recurrence and those
who are more likely to become copers. Unfortunately, it does not target cognitive
or sensory reweighting alterations, that are both relevant in sport to manage
gameplay demands.\r\n "

text: "Stateful signatures like the NIST standardized signature schemes LMS and
XMSS provide an efficient and mature realization of post-quantum secure signature
schemes. They are recommended for long-term use cases like e.g. firmware signing.
However, stateful signature schemes require to properly manage a so-called state.
In stateful signature schemes like LMS and XMSS, signing keys consist of a set
of keys of a one-time signature scheme and it has to be guaranteed that each one-time
key is used only once. This is done by updating a state in each signature computation,
basically recording which one-time keys have already been used. While this is
straightforward in centralized systems, in distributed systems like secure enclaves
consisting of e.g. multiple hardware security modules (HSMs) with limited communication
keeping a distributed state that at any point in time is consistent among all
parties involved presents a challenge. This challenge is not addressed by the
current standardization processes. \r\nIn this paper we present a security model
for the distributed key management of post-quantum secure stateful signatures
like XMSS and LMS. We also present a simple, efficient, and easy to implement
protocol proven secure in this security model, i.e. the protocol guarantees at
any point in time a consistent state among the parties in a distributed system,
like a distributed security enclave. The security model is defined in the universal
composabilty (UC) framework by Ran Canetti by providing an ideal functionality
for the distributed key management for stateful signatures. Hence our protocol
remains secure even if arbitrarily composed with other instances of the same or
other protocols, a necessity for the security of distributed key management protocols.
Our main application are security enclaves consisting of HSMs, but the model and
the protocol can easily be adapted to other scenarios of distributed key management
of stateful signature schemes."

text: Abstract. Liquid Metal Embrittlement (LME) cracking is a well-documented
issue encountered during resistance spot welding (RSW) of zinc-coated advanced
high-strength steels (AHSS) in automotive manufacturing. Given that existing research
has predominantly focused on laboratory-scale samples and lacks investigation
into the load-bearing capacity of joints under crash conditions, this study aims
to fill these gaps by analyzing third-generation zinc-coated AHSS. S-Rail components
were produced through stamping to replicate real-world manufacturing conditions
and geometries of automotive parts. To account for the disturbances typically
encountered in production, samples with LME cracks were intentionally fabricated.
Subsequently, a modified three-point bending test, assisted by numerical simulations,
was developed to effectively apply loads to the weld spots of the S-Rail components.
Results from crash tests demonstrated that observed light crack severity does
not significantly compromise the joint's load-bearing capacity or lead to earlier
joint failure.

text: Abstract. In the field of online condition monitoring, non-destructive
testing methods using active acoustic testing [1] emerged as innovative tools.
These techniques are particularly effective because damage in joined structures
leads to significant changes in their vibrational characteristics. However, the
consistent use of online condition monitoring through active acoustic testing
combined with complex pattern recognition for early crack detection in joined
components has not yet been fully established. This research aims to develop an
online crack detection system employing pattern recognition techniques under cyclic
loading during fatigue tests, utilizing non-contact active acoustic testing with
laser vibrometry. Due to the wide range of materials that can be joined, mechanical
joining processes can be used in many different industry branches. Self-pierce
riveting (SPR), in particular, is a well-established joining process. Therefore,
the investigations for online crack detection initially focus on SPR joints. To
achieve this, the fatigue behavior of SPR joints in a lap-shear configuration
was characterized. Experimental fatigue testing demonstrated that SPR joint failure
occurs either through cracks propagating in the sheet material away from the rivet
or in the rivet foot, depending on the material combination. Laser vibrometry
has been successfully used as a crack detection system and has proven to be effective
in detecting crack initiation in SPR joints. Cracks can be detected without contact
regardless of the material combination, the damage location, the size of the damage,
or the type of damage. The optimization of the crack detection system involved
several key enhancements, including adjusting data acquisition to improve crack
detection, incorporating principal component analysis (PCA) to reduce dimensionality,
and implementing a classification model based on a global training dataset. An
intuitive, problem-specific software demonstrator for analyzing the crack initiation
behavior of SPR joints under cyclic loading was developed and iteratively optimized.
Future work will focus on the implementation of an autoencoder network to further
enhance crack detection capabilities.

text: The generation of optically broadband Nyquist pulse sequences using an integrated
Mach-Zehnder modulator (MZM) in a thin-film lithium-niobate (TFLN) platform with
repetition rates of 5 to 32 GHz and optical bandwidths of up to 160 GHz is demonstrated.
Nyquist pulse sequences with high optical bandwidth can be used as synchronization
and control signals in quantum sources based on photon pair generation.
