multi-input-conditioned image composition model that incorporates a sketch as a
novel modal, al... | http://arxiv.org/abs/2304.09748v1 |
When reflected from an interface, a laser beam generally drifts and tilts
away from the path predicted by ray optics, an intriguing consequence of its
finite transverse extent. Such beam shifts manifest more dramatically for
structured light fields, and in particular for optical vortices. Upon
reflection, a field conta... | http://arxiv.org/abs/2309.14083v1 |
Like speech, signs are composed of discrete, recombinable features called
phonemes. Prior work shows that models which can recognize phonemes are better
at sign recognition, motivating deeper exploration into strategies for modeling
sign language phonemes. In this work, we learn graph convolution networks to
recognize ... | http://arxiv.org/abs/2310.00195v1 |
The problem of finding a maximum $2$-matching without short cycles has
received significant attention due to its relevance to the Hamilton cycle
problem. This problem is generalized to finding a maximum $t$-matching which
excludes specified complete $t$-partite subgraphs, where $t$ is a fixed
positive integer. The poly... | http://arxiv.org/abs/2310.20245v1 |
We present the analysis of the full MaNGA DR17 sample to characterize its
population of compact galaxies. We focus on galaxies that fill the stellar mass
(M$_{\star}$) gap between compact elliptical galaxies (cEs; $8 \lesssim \log
\left(M_{\star} / M_{\odot} \right) \lesssim 10$) and compact massive galaxies
(CMGs; $10... | http://arxiv.org/abs/2309.12394v1 |
In this preprint I propose that the non local discrete-state-in-continuum
model previously successfully used to describe the inelastic electron molecule
collisions can also be used to model the electron photo-detachment from the
molecular anions. The basic theory is sketched and the approach is tested on
the model of e... | http://arxiv.org/abs/2309.05830v1 |
Quantum Darwinism explains the emergence of classical objectivity within a
quantum universe. However, to date most research in quantum Darwinism has
focused on specific models and their stationary properties. To further our
understanding of the quantum-to-classical transition it appears desirable to
identify the genera... | http://arxiv.org/abs/2309.03299v1 |
This is the first of two companion papers where we prove that the recently
discovered non perturbative mechanism capable of giving mass to elementary
fermions, in the presence of weak interactions can also generate a mass for the
$W$, and can thus be used as a viable alternative to the Higgs scenario. The
non perturbat... | http://arxiv.org/abs/2306.00115v2 |
The expanding market for e-comics has spurred interest in the development of
automated methods to analyze comics. For further understanding of comics, an
automated approach is needed to link text in comics to characters speaking the
words. Comics speaker detection research has practical applications, such as
automatic ... | http://arxiv.org/abs/2306.17469v2 |
The Internet is used by billions of users every day because it offers fast
and free communication tools and platforms. Nevertheless, with this significant
increase in usage, huge amounts of spam are generated every second, which
wastes internet resources and, more importantly, users' time. This study
investigates the u... | http://arxiv.org/abs/2310.05953v2 |
Lattice symmetries are central to the characterization of electronic
topology. Recently, it was shown that Green's function eigenvectors form a
representation of the space group. This formulation has allowed the
identification of gapless topological states even when quasiparticles are
absent. Here we demonstrate the pr... | http://arxiv.org/abs/2301.13870v2 |
In this paper we present an efficient active-set method for the solution of
convex quadratic programming problems with general piecewise-linear terms in
the objective, with applications to sparse approximations and
risk-minimization. The method exploits the structure of the piecewise-linear
terms appearing in the objec... | http://arxiv.org/abs/2302.14497v1 |
A divisibility relation on ultrafilters is defined as follows: ${\cal
F}\hspace{1mm}\widetilde{\mid}\hspace{1mm}{\cal G}$ if and only if every set in
$\cal F$ upward closed for divisibility also belongs to $\cal G$. After
describing the first $\omega$ levels of this quasiorder, in this paper we
generalize the process o... | http://arxiv.org/abs/2306.00101v4 |
