solution. We a... | http://arxiv.org/abs/2308.04095v1 |
Macroscopic superconducting components are an important building block of
various quantum circuits. Since several of the envisioned applications require
exposure to magnetic fields, it is of utmost importance to explore the impact
of magnetic fields on their performance. Here we explore the complex pattern of
magnetic ... | http://arxiv.org/abs/2305.02418v2 |
In latest years, deep learning has gained a leading role in the pansharpening
of multiresolution images. Given the lack of ground truth data, most deep
learning-based methods carry out supervised training in a reduced-resolution
domain. However, models trained on downsized images tend to perform poorly on
high-resoluti... | http://arxiv.org/abs/2307.14403v1 |
Code-mixing and script-mixing are prevalent across online social networks and
multilingual societies. However, a user's preference toward code-mixing depends
on the socioeconomic status, demographics of the user, and the local context,
which existing generative models mostly ignore while generating code-mixed
texts. In... | http://arxiv.org/abs/2309.02915v1 |
TlBiSSe is a rare realization of a 3D semimetal with a conically dispersing
band that has an optical response which is well isolated from other
contributions in a broad range of photon eneries. We report optical and
magneto-optical spectroscopy on this material. When the compound is chemically
tuned into a state of the... | http://arxiv.org/abs/2301.06389v1 |
Nowadays, systematic security risk analysis plays a vital role in the
automotive domain. The demand for advanced driver assistance systems and
connectivity of vehicles to the internet makes cyber-security a crucial
requirement for vehicle manufacturers. This paper summarizes the risk analysis
method stated in the recen... | http://arxiv.org/abs/2307.02261v1 |
In this work, we tentatively assign the $Y(4500)$ as the
$[uc]_{\tilde{A}}[\overline{uc}]_{V}+[uc]_{V}[\overline{uc}]_{\tilde{A}}+[dc]_{\tilde{A}}[\overline{dc}]_{V}
+[dc]_{V}[\overline{dc}]_{\tilde{A}}$ tetraquark state with the quantum numbers
$J^{PC}=1^{--}$, and study the three-body strong decay $Y(4500)\to
D^{*-}D... | http://arxiv.org/abs/2304.14153v2 |
Vehicle trajectories can offer the most precise and detailed depiction of
traffic flow and serve as a critical component in traffic management and
control applications. Various technologies have been applied to reconstruct
vehicle trajectories from sparse fixed and mobile detection data. However,
existing methods predo... | http://arxiv.org/abs/2306.05627v1 |
Skyrmions in an antiferromagnet can travel as solitary waves in stark
contrast to the situation in ferromagnets. Traveling skyrmion solutions have
been found numerically in chiral antiferromagnets. We study head-on collision
events between two skyrmions. We find that the result of the collision depends
on the initial v... | http://arxiv.org/abs/2305.13515v2 |
Can social power endow social robots with the capacity to persuade? This
paper represents our recent endeavor to design persuasive social robots. We
have designed and run three different user studies to investigate the
effectiveness of different bases of social power (inspired by French and
Raven's theory) on peoples' ... | http://arxiv.org/abs/2307.06007v2 |
Efforts to model viral cascades provide a vital view into how they form and
spread. A range of methods, such as Multivariate Hawkes Processes or network
inference algorithms, attempt to decompose cascades into constituent components
via inference -- by constructing an underlying network of influence, or by
generating d... | http://arxiv.org/abs/2302.12874v1 |
The solar magnetic fields emerging from the photosphere into the chromosphere
and corona are comprised of a combination of "closed" and "open" fields. The
closed magnetic field lines are defined as those having both ends rooted in the
solar surface, while the open field lines are those having one end extending
out into... | http://arxiv.org/abs/2304.07649v1 |
Continual learning has recently attracted attention from the research
community, as it aims to solve long-standing limitations of classic
supervisedly-trained models. However, most research on this subject has tackled
continual learning in simple image classification scenarios. In this paper, we
present a benchmark of ... | http://arxiv.org/abs/2304.10335v2 |
