Recent VLBI monitoring has found transverse motions of the M87 jet. However,
due to the limited cadence of previous observations, details of the transverse
motion have not been fully revealed yet. We have regularly monitored the M87
jet at KVN and VERA Array (KaVA) 22 GHz from December 2013 to June 2016. The
average ti... | http://arxiv.org/abs/2303.01106v1 |
Many molecular systems and physical phenomena are controlled by local
fluctuations and microscopic dynamical rearrangements of the constitutive
interacting units that are often difficult to detect. This is the case, for
example, of phase transitions, phase equilibria, nucleation events, and defect
propagation, to menti... | http://arxiv.org/abs/2302.09673v2 |
Any system of bisectors (in the sense of abstract Voronoi diagrams) defines
an arrangement of simple curves in the plane. We define Voronoi-like graphs on
such an arrangement, which are graphs whose vertices are locally Voronoi. A
vertex $v$ is called locally Voronoi, if $v$ and its incident edges appear in
the Voronoi... | http://arxiv.org/abs/2303.06669v1 |
Robust watermarking tries to conceal information within a cover image/video
imperceptibly that is resistant to various distortions. Recently, deep
learning-based approaches for image watermarking have made significant
advancements in robustness and invisibility. However, few studies focused on
video watermarking using ... | http://arxiv.org/abs/2305.02781v1 |
We present an approach for mobile robots to recognize scenes in object
arrangements distributed across cluttered environments. Recognition is enabled
by intertwining the robot's search for objects and the assignment of found
objects to scenes. Our scene model called "Implicit Shape Model (ISM) trees"
allows these two t... | http://arxiv.org/abs/2301.10672v3 |
Imitation from observation (IfO) is a learning paradigm that consists of
training autonomous agents in a Markov Decision Process (MDP) by observing
expert demonstrations without access to its actions. These demonstrations could
be sequences of environment states or raw visual observations of the
environment. Recent wor... | http://arxiv.org/abs/2302.06540v1 |
We provide a quantitative evaluation of non-Markovianity (NM) for an XX chain
of interacting qubits with one end coupled to a reservoir. The NM of several
non-Markovian spectral densities is assessed in terms of various quantum state
distance (QSD) measures. Our approach is based on the construction of the
density matr... | http://arxiv.org/abs/2301.09323v2 |
Skip connections and normalisation layers form two standard architectural
components that are ubiquitous for the training of Deep Neural Networks (DNNs),
but whose precise roles are poorly understood. Recent approaches such as Deep
Kernel Shaping have made progress towards reducing our reliance on them, using
insights ... | http://arxiv.org/abs/2302.10322v1 |
Self-supervised learning is gaining considerable attention as a solution to
avoid the requirement of extensive annotations in representation learning on
graphs. Current algorithms are based on contrastive learning, which is
computation an memory expensive, and the assumption of invariance under certain
graph augmentati... | http://arxiv.org/abs/2303.08644v2 |
Decentralized optimization is typically studied under the assumption of
noise-free transmission. However, real-world scenarios often involve the
presence of noise due to factors such as additive white Gaussian noise channels
or probabilistic quantization of transmitted data. These sources of noise have
the potential to... | http://arxiv.org/abs/2307.14942v1 |
We report high-quality H${\alpha}$/CO, imaging spectroscopy of nine massive
(log median stellar mass = 10.65 $M_{\odot}$), disk galaxies on the
star-forming, main sequence (henceforth `SFGs'), near the peak of cosmic galaxy
evolution ($z\sim$1.1-2.5), taken with the ESO-Very Large Telescope, IRAM-NOEMA
and Atacama Larg... | http://arxiv.org/abs/2305.02959v2 |
Given a system of triangles in the plane $\mathbb{R}^2$ along with given data
of function and gradient values at the vertices, we describe the general
pattern of local linear methods invoving only four smooth standard shape
functions which results in a spline function fitting the given value and
gradient data value wit... | http://arxiv.org/abs/2308.15201v1 |
