U Equ is an unusual maser-hosting IR source discovered in the 1990s. It was
tentatively classified as a post-AGB star with a unique optical spectrum
displaying rare emission and absorption features from molecular gas. In 2022,
we discovered that its optical spectrum has drastically changed. Methods:
Optical high-resolu... | http://arxiv.org/abs/2308.10747v1 |
The shape of atomic nuclei is often interpreted to possess a quadrupole
deformation that fluctuates around some average profile. We investigate the
impact of nuclear shape fluctuations on the initial state geometry in heavy ion
collisions, particularly its eccentricity $\varepsilon_2$ and inverse size
$d_{\perp}$, whic... | http://arxiv.org/abs/2301.03556v2 |
Subword tokenization is a key part of many NLP pipelines. However, little is
known about why some tokenizer and hyperparameter combinations lead to better
downstream model performance than others. We propose that good tokenizers lead
to \emph{efficient} channel usage, where the channel is the means by which some
input ... | http://arxiv.org/abs/2306.16842v1 |
A numbering $f$ of a graph $G$ of order $n$ is a labeling that assigns
distinct elements of the set $\left\{ 1,2,\ldots ,n\right\} $ to the vertices
of $G$. The strength $\textrm{str}_{f}\left( G\right)$ of a numbering
$f:V\left( G\right) \rightarrow \left\{ 1,2,\ldots ,n\right\} $ of $G$ is
defined by% \begin{equation... | http://arxiv.org/abs/2304.00859v1 |
Non-radiating protons in the radio lobes have an essential role to form the
jet morphology which is shown by recent radio and X-ray observations. However,
since protons and electrons are not always in energy equilibrium due to weak
Coulomb coupling, it is difficult to estimate the energy contribution of
protons for inf... | http://arxiv.org/abs/2310.02109v1 |
An electromagnetic wave propagating through a waveguide with a strongly
coupled superconducting artificial two-level atom exhibits an evolving
superposition with the atom. The Rabi oscillations in the atom result from a
single excitation-relaxation, corresponding to photon absorption and stimulated
emission from/to the... | http://arxiv.org/abs/2309.01563v2 |
Over the past decade, machine learning has demonstrated impressive results,
often surpassing human capabilities in sensing tasks relevant to autonomous
flight. Unlike traditional aerospace software, the parameters of machine
learning models are not hand-coded nor derived from physics but learned from
data. They are aut... | http://arxiv.org/abs/2310.03217v1 |
Real-world grasp detection is challenging due to the stochasticity in grasp
dynamics and the noise in hardware. Ideally, the system would adapt to the real
world by training directly on physical systems. However, this is generally
difficult due to the large amount of training data required by most grasp
learning models... | http://arxiv.org/abs/2306.06489v1 |
A time lens allows one to stretch or compress optical waveforms in time,
similar to the conventional lens in space. However, a single-time-lens imaging
system always imparts a residual temporal chirp on the image, which may be
detrimental for quantum networks, where the temporal image interacts with other
fields. We sh... | http://arxiv.org/abs/2307.09493v1 |
The last year has seen astonishing progress in text-prompted image generation
premised on the idea of a cross-modal representation space in which the text
and image domains are represented jointly. In ASR, this idea has found
application as joint speech-text encoders that can scale to the capacities of
very large param... | http://arxiv.org/abs/2308.06125v1 |
Vision Transformers have enabled recent attention-based Deep Learning (DL)
architectures to achieve remarkable results in Computer Vision (CV) tasks.
However, due to the extensive computational resources required, these
architectures are rarely implemented on resource-constrained platforms. Current
research investigate... | http://arxiv.org/abs/2303.04440v2 |
IoT device identification is the process of recognizing and verifying
connected IoT devices to the network. This is an essential process for ensuring
that only authorized devices can access the network, and it is necessary for
network management and maintenance. In recent years, machine learning models
have been used w... | http://arxiv.org/abs/2307.08955v1 |
The VEGA-3 laser system at the Centro de L\'{a}seres Pulsados (CLPU) delivers
laser pulses up to 1PW at 1Hz repetition rate, focused to intensities up to
