With the growth of online news over the past decade, empirical studies on
political discourse and news consumption have focused on the phenomenon of
filter bubbles and echo chambers. Yet recently, scholars have revealed limited
evidence around the impact of such phenomenon, leading some to argue that
partisan segregati... | http://arxiv.org/abs/2301.08832v2 |
The orbits in $\Gamma_{\infty}(3) \backslash \Gamma(3)$ are in bijection with
sets of invariants satisfying certain relations. We explain how wedge product
matrices give an alternative definition of the invariants of matrix orbits.
This new method provides the possibility of performing similar computations
with other c... | http://arxiv.org/abs/2306.12615v2 |
The advent of Quantum Computing has influenced researchers around the world
to solve multitudes of computational problems with the promising technology.
Feasibility of solutions for computational problems, and representation of
various information, may allow quantum computing to replace classical computer
in near futur... | http://arxiv.org/abs/2302.07089v1 |
Several natural and industrial processes involve the extraction or retention
of a solute by a fluid invading a network of channels. Examples include aquifer
contamination, chemical filtration, and coffee extraction. We propose a
continuum equation to model these processes, parametrized by the P\'eclet
number and the ra... | http://arxiv.org/abs/2304.03161v2 |
It is a classic result of Selberg in the 1950's that $\theta_2 = 2/3$, where
$\theta_2$ is the level of distribution of the divisor function in arithmetic
progressions (defined more precisely below). Selberg applies this estimate,
together with his $\Lambda^2$ sieve, to prove weak forms of the binary Goldbach
and twin ... | http://arxiv.org/abs/2303.08093v2 |
Informal natural language that describes code functionality, such as code
comments or function documentation, may contain substantial information about a
programs intent. However, there is typically no guarantee that a programs
implementation and natural language documentation are aligned. In the case of a
conflict, le... | http://arxiv.org/abs/2310.01831v2 |
Aims. A realistic model of magnetic linkage between a central object and its
accretion disk is a prerequisite for understanding the spin history of stars
and stellar remnants. To this end, we aim to provide an analytic model in
agreement with magnetohydrodynamic (MHD) simulations.
Methods. For the first time, we wrot... | http://arxiv.org/abs/2308.14910v1 |
Current privacy research on large language models (LLMs) primarily focuses on
the issue of extracting memorized training data. At the same time, models'
inference capabilities have increased drastically. This raises the key question
of whether current LLMs could violate individuals' privacy by inferring
personal attrib... | http://arxiv.org/abs/2310.07298v2 |
In this research, we deal with the problem of visual question answering (VQA)
in remote sensing. While remotely sensed images contain information significant
for the task of identification and object detection, they pose a great
challenge in their processing because of high dimensionality, volume and
redundancy. Furthe... | http://arxiv.org/abs/2306.14264v1 |
We investigate deformations of the Kerr-(A)dS near horizon geometry and
derive partial infinitesimal rigidity results for it. The proof comprises two
parts. First, we follow the analysis of Jezierski and Kami\'nski [Gen Rel Grav
45 (2013) 987--1004] to eliminate all but a finite number of Fourier modes of
linear pertur... | http://arxiv.org/abs/2310.06186v1 |
Existing melody harmonization models have made great progress in improving
the quality of generated harmonies, but most of them ignored the emotions
beneath the music. Meanwhile, the variability of harmonies generated by
previous methods is insufficient. To solve these problems, we propose a novel
LSTM-based Hierarchic... | http://arxiv.org/abs/2306.03718v4 |
