The measurement data from the boundary layer measurement masts in
Hamburg-Billwerder (Germany) and Hyytiala (Finland) make thermals visible. For
this, the temperature and humidity data must first be transformed to be
independent of altitude. The subsequent visualisation of this data shows an
impressive cross-section of... | http://arxiv.org/abs/2307.03753v1 |
Many sequential decision-making tasks require satisfaction of multiple,
partially contradictory objectives. Existing approaches are monolithic, namely
all objectives are fulfilled using a single policy, which is a function that
selects a sequence of actions. We present auction-based scheduling, a modular
framework for ... | http://arxiv.org/abs/2310.11798v2 |
Entity linking methods based on dense retrieval are an efficient and widely
used solution in large-scale applications, but they fall short of the
performance of generative models, as they are sensitive to the structure of the
embedding space. In order to address this issue, this paper introduces DUCK, an
approach to in... | http://arxiv.org/abs/2305.12027v2 |
We numerically and experimentally demonstrated a higher-order topological
state in a three-dimensional (3D) photonic crystal (PhC) with a complete
photonic bandgap. Two types of cubic lattices were designed with different
topological invariants, which were theoretically and numerically confirmed by
the finite differenc... | http://arxiv.org/abs/2307.05336v1 |
We present 12CO (J=2-1) sensitive molecular line and 1.3 mm continuum
observations made with the Submillimeter Array (SMA) of the bipolar outflow
associated with the young star located in the Bok globule known as CB 26. The
SMA observations were carried out in its extended configuration allowing us to
study the kinemat... | http://arxiv.org/abs/2301.07877v1 |
As the size of accessible compound libraries expands to over 10 billion, the
need for more efficient structure-based virtual screening methods is emerging.
Different pre-screening methods have been developed for rapid screening, but
there is still a lack of structure-based methods applicable to various proteins
that pe... | http://arxiv.org/abs/2310.00681v3 |
Multi-agent Reinforcement learning (MARL) studies the behaviour of multiple
learning agents that coexist in a shared environment. MARL is more challenging
than single-agent RL because it involves more complex learning dynamics: the
observations and rewards of each agent are functions of all other agents. In
the context... | http://arxiv.org/abs/2304.13004v1 |
Oscillations are abundant in the solar corona. Coronal loop oscillations are
typically studied using highly idealised models of magnetic flux tubes. In
order to improve our understanding of coronal oscillations, it is necessary to
consider the effect of realistic magnetic field topology and density
structuring. We anal... | http://arxiv.org/abs/2306.02770v1 |
This paper describes our submission to the MEDIQA-Chat 2023 shared task for
automatic clinical note generation from doctor-patient conversations. We report
results for two approaches: the first fine-tunes a pre-trained language model
(PLM) on the shared task data, and the second uses few-shot in-context learning
(ICL) ... | http://arxiv.org/abs/2305.02220v2 |
The outdoor navigation capabilities of ground robots have improved
significantly in recent years, opening up new potential applications in a
variety of settings. Cost-based representations of the environment are
frequently used in the path planning domain to obtain an optimized path based
on various objectives, such as... | http://arxiv.org/abs/2308.15978v1 |
It is well known that there are several long-standing problems implying the
discordance of the $\Lambda$CDM model. Although most of the models proposed to
resolve these problems assume that dark matter is pressureless, it is still
possible that dark matter is not cold, as current observations have not ruled
out this po... | http://arxiv.org/abs/2303.00961v2 |
In this paper, we found new classes of solutions to the Einstein-Maxwell
field equations with matter anisotropic distribution incorporating a particular
form of electric field intensity within the framework of general relativity. We
use a metric potential or ansatz that depends on an adjustable parameter in
order to ge... | http://arxiv.org/abs/2310.00859v1 |
We examine the backreaction effect of the enhanced small-scale scalar
perturbations from the sound speed resonance (SSR) mechanism for primordial
black hole formation in Dirac-Born-Infeld (DBI) inflation on background as well
as curvature perturbation, which can generate a considerable amount of
primordial black holes ... | http://arxiv.org/abs/2307.03747v2 |
