Anisotropic flows $i.e.$ azimuthal anisotropies in particle production are
one of the important probes in characterizing the properties of the strongly
interacting matter created in the relativistic heavy-ion collisions. These
observables are sensitive to both the transport properties as well as the
equation of state (... | http://arxiv.org/abs/2309.06128v3 |
Understanding how local environments influence individual behaviors, such as
voting patterns or suicidal tendencies, is crucial in social science to reveal
and reduce spatial disparities and promote social well-being. With the
increasing availability of large-scale individual-level census data, new
analytical opportuni... | http://arxiv.org/abs/2309.11454v1 |
In this paper, we introduce Libriheavy, a large-scale ASR corpus consisting
of 50,000 hours of read English speech derived from LibriVox. To the best of
our knowledge, Libriheavy is the largest freely-available corpus of speech with
supervisions. Different from other open-sourced datasets that only provide
normalized t... | http://arxiv.org/abs/2309.08105v2 |
Over the past years, one witnesses a growing interest in flat band (FB)
physics which has become a playground for exotic phenomena. In this study, we
address the FB superconductivity in onedimensional stub chain. In contrast to
the sawtooth chain or the creutz ladder, for a given strength of the attractive
electron-ele... | http://arxiv.org/abs/2309.11440v1 |
This study numerically investigated the friction of viscoelastic objects with
grooves. A 3D viscoelastic block with grooves on a rigid substrate is slowly
pushed from the lateral side under uniform pressure on the top surface. The
local friction force at the interface between the block and the substrate obeys
Amontons'... | http://arxiv.org/abs/2309.08111v2 |
In this paper we will study both the finite and infinite-dimensional
representations of the symplectic Lie algebra $\mathfrak{sp}(2n)$ and develop a
polynomial model for these representations. This means that we will associate a
certain space of homogeneous polynomials in a matrix variable, intersected with
the kernel ... | http://arxiv.org/abs/2309.15626v1 |
E-mobility, or electric mobility, has emerged as a pivotal solution to
address pressing environmental and sustainability concerns in the
transportation sector. The depletion of fossil fuels, escalating greenhouse gas
emissions, and the imperative to combat climate change underscore the
significance of transitioning to ... | http://arxiv.org/abs/2309.15140v1 |
In the course of developing digital and future aviation cabin concepts at the
German Aerospace Center, the exploration of user-centered and
acceptance-enhancing methods plays a central role. The challenge here is to
identify the flexible range of requirements of different user groups for a
previously non-existent trans... | http://arxiv.org/abs/2309.05353v1 |
Principal component analysis (PCA) is a widely employed statistical tool used
primarily for dimensionality reduction. However, it is known to be adversely
affected by the presence of outlying observations in the sample, which is quite
common. Robust PCA methods using M-estimators have theoretical benefits, but
their ro... | http://arxiv.org/abs/2309.13531v1 |
An open research question has been whether a single human can supervise a
true heterogeneous swarm of robots completing tasks in real world environments.
A general concern is whether or not the human's workload will be taxed to the
breaking point. The Defense Advanced Research Projects Agency's OFFsensive
Swarm-Enabled... | http://arxiv.org/abs/2308.00102v1 |
