same way, can become boring for the robot's user(s), therefore, assistive
robots must find creative ways to perform tasks in the household. In this
paper, we present... | http://arxiv.org/abs/2307.00114v1 |
$p$-form electrodynamics in $d\geq 2$ dimensions is shown to emerge as the
edge modes of a topological field theory with a precise set of boundary
conditions, through the Hamiltonian reduction of its action. Electric and
magnetic charges correspond to Noether ones in the topological field theory.
For chiral $p$-forms, ... | http://arxiv.org/abs/2309.15923v2 |
Detection of radar signals without assistance from the radar transmitter is a
crucial requirement for emerging and future shared-spectrum wireless networks
like Citizens Broadband Radio Service (CBRS). In this paper, we propose a
supervised deep learning-based spectrum sensing approach called RadYOLOLet that
can detect... | http://arxiv.org/abs/2309.12094v1 |
A recent trend in deep learning algorithms has been towards training large
scale models, having high parameter count and trained on big dataset. However,
robustness of such large scale models towards real-world settings is still a
less-explored topic. In this work, we first benchmark the performance of these
models und... | http://arxiv.org/abs/2309.07499v1 |
We study the trigonometric quantum spin-Calogero-Sutherland model, and the
Haldane-Shastry spin chain as a special case, using a Bethe-ansatz analysis. We
harness the model's Yangian symmetry to import the standard tools of
integrability for Heisenberg spin chains into the world of integrable
long-range models with spi... | http://arxiv.org/abs/2308.16865v2 |
We consider the effect of finite time extinction mechanisms (FTEM) such as
(1) semi-linear harvesting terms, and (2) quasi-linear fast diffusion terms on
two species Lokta-Volterra competition models. We show that these mechanisms
can alter classical dynamics of competitive exclusion, and weak and strong
competition by... | http://arxiv.org/abs/2305.19572v1 |
Since quantum computing is currently in the NISQ-Era, compilation strategies
to reduce the number of gates executed on specific hardware are required. In
this work, we utilize the concept of synthesis of a data structure called
Clifford tableaus, focusing on applying CNOTs within the respective
connectivity graph of th... | http://arxiv.org/abs/2309.08972v2 |
The solar ultraviolet intensities of spectral lines originating from Li- and
Na-like ions have been observed to surpass the expectations derived from
plasmas with coronal approximation. The violation of the coronal approximation
can be partially attributed to non-equilibrium ionization (NEI) due to dynamic
processes oc... | http://arxiv.org/abs/2310.00295v2 |
The variety of complex algorithmic approaches for tackling time-series
classification problems has grown considerably over the past decades, including
the development of sophisticated but challenging-to-interpret
deep-learning-based methods. But without comparison to simpler methods it can
be difficult to determine whe... | http://arxiv.org/abs/2303.17809v1 |
Organoids are self-organized 3D cell clusters that closely mimic the
architecture and function of in vivo tissues and organs. Quantification of
organoid morphology helps in studying organ development, drug discovery, and
toxicity assessment. Recent microscopy techniques provide a potent tool to
acquire organoid morphol... | http://arxiv.org/abs/2309.04190v4 |
We study the behavior of the smallest possible constants $d(a,b)$ and $d_n$
in Hardy inequalities $$
\int_a^b\left(\frac{1}{x}\int_a^xf(t)dt\right)^p\,dx\leq d(a,b)\,\int_a^b
[f(x)]^p dx $$ and $$
\sum_{k=1}^{n}\Big(\frac{1}{k}\sum_{j=1}^{k}a_j\Big)^p\leq
d_n\,\sum_{k=1}^{n}a_k^p. $$ The exact rate of convergence of $d... | http://arxiv.org/abs/2310.00281v1 |
The biggest Breast cancer is increasingly a major factor in female
fatalities, overtaking heart disease. While genetic factors are important in
the growth of breast cancer, new research indicates that environmental factors
also play a substantial role in its occurrence and progression. The literature

Gender biases in language generation systems are challenging to mitigate. One
possible source for these biases is gender representation disparities in the
training and evaluation data. Despite recent progress in documenting this
problem and many attempts at mitigating it, we still lack shared methodology
and tooling to... | http://arxiv.org/abs/2308.16871v1 |
