geometric phase acquired by the state. Specifically, we derive and examine
three tight lo... | http://arxiv.org/abs/2305.12156v3 |
For a given function $F$ from $\mathbb F_{p^n}$ to itself, determining
whether there exists a function which is CCZ-equivalent but EA-inequivalent to
$F$ is a very important and interesting problem. For example, K\"olsch
\cite{KOL21} showed that there is no function which is CCZ-equivalent but
EA-inequivalent to the in... | http://arxiv.org/abs/2306.13718v2 |
Finding an efficient way to adapt robot trajectory is a priority to improve
overall performance of robots. One approach for trajectory planning is through
transferring human-like skills to robots by Learning from Demonstrations (LfD).
The human demonstration is considered the target motion to mimic. However,
human moti... | http://arxiv.org/abs/2304.05703v1 |
Van der Waals heterostructures of two-dimensional materials have opened up
new frontiers in condensed matter physics, unlocking unexplored possibilities
in electronic and photonic device applications. However, the investigation of
wide-gap high-$\kappa$ layered dielectrics for devices based on van der Waals
structures ... | http://arxiv.org/abs/2307.13431v1 |
Ehrenfeucht-Fra\"iss\'e games provide a fundamental method for proving
elementary equivalence (and equivalence up to a certain quantifier rank) of
relational structures. We investigate the soundness and completeness of this
method in the more general context of semiring semantics. Motivated originally
by provenance ana... | http://arxiv.org/abs/2308.04910v1 |
In this paper, we deal with the notions of naturality from category theory
and definablity from model theory and their interactions. In this regard, we
present three results. First, we show, under some mild conditions, that
naturality implies definablity. Second, by using the reverse Easton iteration
of Cohen forcing n... | http://arxiv.org/abs/2309.02090v1 |
The Quantum Angle Generator (QAG) is a new full Quantum Machine Learning
model designed to generate accurate images on current Noise Intermediate Scale
(NISQ) Quantum devices. Variational quantum circuits form the core of the QAG
model, and various circuit architectures are evaluated. In combination with the
so-called ... | http://arxiv.org/abs/2307.05253v4 |
We present a novel implementation of a genuinely $4^{\rm th}$-order accurate
finite volume scheme for multidimensional classical and special relativistic
magnetohydrodynamics (MHD) based on the constrained transport (CT) formalism.
The scheme introduces several novel aspects when compared to its predecessors
yielding a... | http://arxiv.org/abs/2310.11831v4 |
Surface meshes are a favoured domain for representing structural and
functional information on the human cortex, but their complex topology and
geometry pose significant challenges for deep learning analysis. While
Transformers have excelled as domain-agnostic architectures for
sequence-to-sequence learning, the quadra... | http://arxiv.org/abs/2303.11909v3 |
One of the main challenges of the sign language recognition task is the
difficulty of collecting a suitable dataset due to the gap between
hard-of-hearing and hearing societies. In addition, the sign language in each
country differs significantly, which obliges the creation of new data for each
of them. This paper pres... | http://arxiv.org/abs/2305.14527v3 |
A pair of interferometers can be coupled by allowing one path from each to
overlap such that if the particles meet in this overlap region, they
annihilate. It was shown by one of us over thirty years ago that such
annihilation-coupled interferometers can exhibit apparently paradoxical
behaviour. More recently, Bose et ... | http://arxiv.org/abs/2305.14241v2 |
News sources undergo the process of selecting newsworthy information when
covering a certain topic. The process inevitably exhibits selection biases,
i.e. news sources' typical patterns of choosing what information to include in
news coverage, due to their agenda differences. To understand the magnitude and
implication... | http://arxiv.org/abs/2304.03414v1 |
We resolve difficulties in training and sampling from a discrete generative
model by learning a smoothed energy function, sampling from the smoothed data
manifold with Langevin Markov chain Monte Carlo (MCMC), and projecting back to
the true data manifold with one-step denoising. Our Discrete Walk-Jump Sampling
formali... | http://arxiv.org/abs/2306.12360v2 |
As an alternative solution for quick disaster recovery of backhaul/fronthaul
links, in this paper, a dynamic unmanned aerial vehicles (UAV)-assisted
heterogeneous (HetNet) network equipped with directional terahertz (THz)
antennas is studied to solve the problem of transferring traffic of distributed
small cells. To th... | http://arxiv.org/abs/2307.05535v2 |
