Open-domain question answering (QA) systems are often built with retrieval
modules. However, retrieving passages from a given source is known to suffer
from insufficient knowledge coverage. Alternatively, prompting large language
models (LLMs) to generate contextual passages based on their parametric
knowledge has been... | http://arxiv.org/abs/2310.14393v1 |
We prove that there exists a constant $C$ so that, for all $s,k \in
\mathbb{N}$, if $G$ has average degree at least $k^{Cs^3}$ and does not contain
$K_{s,s}$ as a subgraph then it contains an induced subgraph which is
$C_4$-free and has average degree at least $k$. It was known that some function
of $s$ and $k$ suffice... | http://arxiv.org/abs/2307.08361v2 |
In this paper, the numerical solution of the singular-perturbation Cauchy
problem by Runge-Kutta methods on the Shishkin grid is discussed. Numerical
solutions of the observed problem were obtained using two explicit and one
implicit Runge-Kutta method on the simplest layer-adaptive network. Finally,
the obtained resul... | http://arxiv.org/abs/2306.10607v1 |
We present preliminary results from our spectroscopic survey of
low-luminosity early-type galaxies in the Coma cluster conducted with the
Binospec spectrograph at the 6.5~m MMT. From spatially-resolved profiles of
internal kinematics and stellar population properties complemented with
high-resolution images, we placed ... | http://arxiv.org/abs/2306.08048v1 |
We take a sample of 94 ultraluminous, optical quasars from the search of over
14,486 deg^2 by Onken et al. 2022 in the range 4.4<redshift<5.2 and match them
against the Rapid ASKAP Continuum Survey (RACS) observed on the Australian
Square Kilometre Array Pathfinder (ASKAP). From this most complete sample of
the bright ... | http://arxiv.org/abs/2309.00291v1 |
In this paper we address the problem of path planning in an unknown
environment with an aerial robot. The main goal is to safely follow the planned
trajectory by avoiding obstacles. The proposed approach is suitable for aerial
vehicles equipped with 3D sensors, such as LiDARs. It performs obstacle
avoidance in real tim... | http://arxiv.org/abs/2306.16276v1 |
We demonstrate a novel approach to the structural and electronic property
modification of perovskites, focusing on Pr$_2$CuO$_4$, an undoped parent
compound of a class of electron-doped copper-oxide superconductors. Currents
were passed parallel or perpendicular to the copper-oxygen layers with the
voltage ramped up un... | http://arxiv.org/abs/2302.04385v2 |
Due to the global water crisis there is a strong need for real-time water
quality monitoring with high temporal and spatial resolution. This paper
presents an economical multiparameter water quality monitoring system for
continuous monitoring of fresh waters. It is based on a sensor node that
integrates turbidity, temp... | http://arxiv.org/abs/2307.11630v2 |
Robots "in-the-wild" encounter and must traverse widely varying terrain,
ranging from solid ground to granular materials like sand to full liquids.
Numerous approaches exist, including wheeled and legged robots, each excelling
in specific domains. Screw-based locomotion is a promising approach for
multi-domain mobility... | http://arxiv.org/abs/2301.10878v2 |
Some form of approximately exponential inflation is generally assumed to be
the origin of our present universe. The inflation is thought to be driven by a
scalar field potential where the field first slowly slides along the potential
and then comes to a steep slope where the field rapidly falls and then
oscillates arou... | http://arxiv.org/abs/2304.13577v1 |
Learning involves relations, interactions and connections between learners,
teachers and the world at large. Such interactions are essentially temporal and
unfold in time. Yet, researchers have rarely combined the two aspects (the
temporal and relational aspects) in an analytics framework. Temporal networks
allow model... | http://arxiv.org/abs/2307.12339v1 |
