The Dirichlet--Neumann operator is introduced to accomplish this dimensional
reduction and is expressed via a Taylor series expansion. A recursion formula
is derived t... | http://arxiv.org/abs/2310.17102v1 |
We show that at $N=\infty$ and below its upper critical dimension, $d<d_{\rm
up}$, the critical and tetracritical behaviors of the O($N$) models are
associated with the same renormalization group fixed point (FP) potential. Only
their derivatives make them different with the subtleties that taking their
$N\to\infty$ li... | http://arxiv.org/abs/2301.01021v1 |
There has been a great deal of research on graphs defined on algebraic
structures in the last two decades. In this paper we begin an exploration of
hypergraphs defined on algebraic structures, especially groups, to investigate
whether this can add a new perspective. | http://arxiv.org/abs/2303.00546v1 |
We show that if $X$ is a normal complex quasi-projective variety, the
quasi-Albanese map of which is proper, then the torsionfree nilpotent quotients
of $\pi_1(X)$ are, up to a controlled finite index, the same ones as those of
the normalisation of its quasi-Albanese image. When $X$ is quasi-K\"ahler
smooth, we get the... | http://arxiv.org/abs/2301.11232v4 |
In the present paper, we study the composition operators acting on weighted
Hardy spaces of polynomial growth, which are concerned with norms, spectra and
(semi-)Fredholmness. Firstly, we estimate the norms of the composition
operators with symbols of disk automorphisms. Secondly, we discuss the spectra
of the composit... | http://arxiv.org/abs/2302.08233v1 |
Object-centric representation learning offers the potential to overcome
limitations of image-level representations by explicitly parsing image scenes
into their constituent components. While image-level representations typically
lack robustness to natural image corruptions, the robustness of object-centric
methods rema... | http://arxiv.org/abs/2308.14899v1 |
The advent of computed tomography significantly improves patient health
regarding diagnosis, prognosis, and treatment planning and verification.
However, tomographic imaging escalates concomitant radiation doses to patients,
inducing potential secondary cancer. We demonstrate the feasibility of a
data-driven approach t... | http://arxiv.org/abs/2304.14594v2 |
Representation forgetting refers to the drift of contextualized
representations during continual training. Intuitively, the representation
forgetting can influence the general knowledge stored in pre-trained language
models (LMs), but the concrete effect is still unclear. In this paper, we study
the effect of represent... | http://arxiv.org/abs/2305.05968v1 |
We show that weighted path orders are special instances of a variant of
semantic path orders. Exploiting this fact, we introduce a generalization of
weighted path orders that goes beyond the realm of simple termination.
Experimental data show that generalized weighted path orders are viable. | http://arxiv.org/abs/2307.13973v1 |
Retaining diverse, underrepresented students in computer science and software
engineering programs is a significant concern for universities. In this
chapter, we describe the INSPIRE: STEM for Social Impact program at the
University of Victoria, Canada, which leverages the three principles of
self-determination theory ... | http://arxiv.org/abs/2302.07100v2 |
The graphene-like two-dimensional (2D) silicon carbide or siligraphene has
attracted remarkable attentions, owing to its fascinating physical properties.
Nevertheless, the first high-quality siligraphene, i.e., monolayer Si9C15 was
synthesised very recently, which exhibits an excellent semiconducting
behaviour. In this... | http://arxiv.org/abs/2302.04409v1 |
In this article we provide a three step algorithm to obtain the Closest
Separable State to the given state in Hilbert space dimensions $2\times 2$ and
$2\times 3$, or in the higher dimensional Hilbert spaces, 'Closest Positive
Partial Transpose (PPT) state' for the chosen bipartition. In the process, a
tight lower boun... | http://arxiv.org/abs/2308.06245v1 |
Medical waste, i.e. waste produced during medical activities in hospitals,
clinics and laboratories, represents hazardous waste whose management involves
special care and high costs. However, this kind of waste contains a significant
fraction of highly valued materials that can enter a circular economy process.
To this... | http://arxiv.org/abs/2303.04720v2 |
We compute the $E_2$ pages of the momentum-space and real-space
Atiyah-Hirzebruch spectral sequence (AHSS) for topological crystalline
insulators and superconductors up to three spatial dimensions, considering the
cell decomposition in which if a group action fixes a cell setwise then its
group action fixes the same ce... | http://arxiv.org/abs/2304.01827v1 |
We here report a probable detection of a stellar coronal mass ejection (CME)
in active M dwarf KIC 8093473 by performing an analysis on its time resolved
X-ray spectra observed by XMM-Newton satellite. Compared to the value at
quiescent state and the interstellar one, our spectral modeling returns a
marginal (and proba... | http://arxiv.org/abs/2305.08294v1 |
