We consider the general problem of a Parker-type non-relativistic isothermal
wind from a rotating and magnetic star. Using the magnetohydrodynamics (MHD)
code athena++, we construct an array of simulations in the stellar rotation
rate $\Omega_\ast$ and the isothermal sound speed $c_T$, and calculate the
mass, angular m... | http://arxiv.org/abs/2302.05462v2 |
The tradeoff between precision and performance in molecular simulations can
nowadays be addressed by machine-learned force fields (MLFF), which combine
\textit{ab initio} accuracy with force field numerical efficiency. Different
from conventional force fields however, incorporating relevant electronic
degrees of freedo... | http://arxiv.org/abs/2308.10752v2 |
The research on complex networks has achieved significant progress in
revealing the mesoscopic features of networks. Community detection is an
important aspect of understanding real-world complex systems. We present in
this paper a High-order node proximity Spectral Clustering on
Ratios-of-Eigenvectors (SCOREH+) algori... | http://arxiv.org/abs/2301.02885v2 |
Despite extensive search efforts, direct observations of the first (Pop III)
stars have not yet succeeded. Theoretical studies have suggested that late Pop
III star formation is still possible in pristine clouds of high-mass galaxies,
coexisting with Pop II stars, down to the Epoch of Reionization (EoR). Here we
reasse... | http://arxiv.org/abs/2301.10259v2 |
Heat pumps are a key technology for reducing fossil fuel use in the heating
sector. However, the transition to heat pumps implies an increase in
electricity demand, especially in the cold winter months. Therefore, the
flexible operation of heat pumps will be of high importance to the power
sector. Using an open-source ... | http://arxiv.org/abs/2307.12918v2 |
The Vlasov-Poisson system describes the time evolution of a plasma in the
so-called collisionless regime. The investigation of a high-temperature plasma
that is influenced by an exterior magnetic field is one of the most significant
aspects of thermonuclear fusion research. In this paper, we formulate and
analyze a kin... | http://arxiv.org/abs/2304.02083v2 |
We consider stabilities for the weighted length or energy functional of a
discrete map from a finite weighted graph $(X,m_{E})$ into a smooth Riemannian
manifold $(M,g)$. We prove the non-existence of a stable discrete minimal
immersion or a non-constant stable discrete harmonic map from a finite weighted
graph into ce... | http://arxiv.org/abs/2306.14098v1 |
The topological properties of the Su-Schrieffer-Heeger (SSH) model in the
presence of nearest-neighbor interaction are investigated by means of a
topological marker, generalized from a noninteracting one by utilizing the
single-particle Green's function of the many-body ground state. We find that
despite the marker not... | http://arxiv.org/abs/2308.14534v2 |
We present a simple yet effective approach that can transform the OpenAI
GPT-3.5 model into a reliable motion planner for autonomous vehicles. Motion
planning is a core challenge in autonomous driving, aiming to plan a driving
trajectory that is safe and comfortable. Existing motion planners predominantly
leverage heur... | http://arxiv.org/abs/2310.01415v3 |
Variance-Invariance-Covariance Regularization (VICReg) is a self-supervised
learning (SSL) method that has shown promising results on a variety of tasks.
However, the fundamental mechanisms underlying VICReg remain unexplored. In
this paper, we present an information-theoretic perspective on the VICReg
objective. We be... | http://arxiv.org/abs/2303.00633v4 |
The dynamics by iteration of a function on a compact metric space, sometimes
called a cascade, can be extended to the dynamics of a closed relation on such
a space. Here we apply this relation dynamics to study semiflows (and their
relation extension) as well as hybrid dynamical systems which combine both
continuous ti... | http://arxiv.org/abs/2307.03815v1 |
Exploration bonuses in reinforcement learning guide long-horizon exploration
by defining custom intrinsic objectives. Several exploration objectives like
count-based bonuses, pseudo-counts, and state-entropy maximization are
non-stationary and hence are difficult to optimize for the agent. While this
issue is generally... | http://arxiv.org/abs/2310.18144v4 |
Purpose of review: We review recent advances in algorithmic development and
validation for modeling and control of soft robots leveraging the Koopman
operator theory. Recent findings: We identify the following trends in recent
research efforts in this area. (1) The design of lifting functions used in the
data-driven ap... | http://arxiv.org/abs/2301.09708v2 |
