A drifting wave-ice buoy, which was configured by mounting the OpenMetBuoy on
an ad hoc floating platform that we named Medusa, was deployed at the
L\"utzow-Holm Bay (LHB) marginal ice zone in Antarctica on 4 Feb 2022 during
the 63rd Japanese Antarctica research expedition. The wave-ice buoy,
Medusa-766, survived the A... | http://arxiv.org/abs/2309.13714v1 |
What knowledge can be obtained from the record of a continuous measurement
about the quantum state the measured system was in at the beginning of the
measurement? The task of quantum state retrodiction, the inverse of the more
common state prediction, is rigorously and elegantly addressed in quantum
measurement theory ... | http://arxiv.org/abs/2309.03507v1 |
Whole-plane SLE$_\kappa$ is a random fractal curve between two points on the
Riemann sphere. Zhan established for $\kappa \leq 4$ that whole-plane
SLE$_\kappa$ is reversible, meaning invariant in law under conformal
automorphisms swapping its endpoints. Miller and Sheffield extended this to
$\kappa \leq 8$. We prove wh... | http://arxiv.org/abs/2309.05176v3 |
We present MBAPPE, a novel approach to motion planning for autonomous driving
combining tree search with a partially-learned model of the environment.
Leveraging the inherent explainable exploration and optimization capabilities
of the Monte-Carlo Search Tree (MCTS), our method addresses complex
decision-making in a dy... | http://arxiv.org/abs/2309.08452v1 |
We discuss a continuous family of non-supersymmetric AdS$_3\times
S^3\times{\rm T^4}$ vacua in heterotic and type II supergravities whose
complete Kaluza-Klein spectrum is computed and found to be free from
instabilities. This family is protected as well against some non-perturbative
decay channels, and as such it prov... | http://arxiv.org/abs/2309.03261v2 |
Traditionally, training neural networks to perform semantic segmentation
required expensive human-made annotations. But more recently, advances in the
field of unsupervised learning have made significant progress on this issue and
towards closing the gap to supervised algorithms. To achieve this, semantic
knowledge is ... | http://arxiv.org/abs/2309.12378v2 |
While being decentralized, secure, and reliable, Bitcoin and many other
blockchain-based cryptocurrencies suffer from scalability issues. One of the
promising proposals to address this problem is off-chain payment channels.
Since, not all nodes are connected directly to each other, they can use a
payment network to rou... | http://arxiv.org/abs/2301.01240v1 |
The paper focuses on identifying the causes of student performance to provide
personalized recommendations for improving pass rates. We introduce the need to
move beyond predictive models and instead identify causal relationships. We
propose using causal discovery techniques to achieve this. The study's main
contributi... | http://arxiv.org/abs/2309.13066v1 |
Object detection and segmentation are two core modules of an autonomous
vehicle perception system. They should have high efficiency and low latency
while reducing computational complexity. Currently, the most commonly used
algorithms are based on deep neural networks, which guarantee high efficiency
but require high-pe... | http://arxiv.org/abs/2306.17485v1 |
Pairs of similar compounds that only differ by a small structural
modification but exhibit a large difference in their binding affinity for a
given target are known as activity cliffs (ACs). It has been hypothesised that
quantitative structure-activity relationship (QSAR) models struggle to predict
ACs and that ACs thu... | http://arxiv.org/abs/2301.13644v1 |
This article conducts an extensive examination of the persisting challenges
related to smart contract attacks within blockchain networks, with a particular
focus on the reentrancy attack. It emphasizes the inherent vulnerabilities
embedded in the programming languages commonly employed for smart contract
development, p... | http://arxiv.org/abs/2309.17200v2 |
