In this paper, we deal with a classical object, namely, a nonhyperbolic limit
cycle in a system of smooth autonomous ordinary differential equations. While

Lightshift of a state due to the applied laser in an atomic system vanishes

Widely-used LiDAR-based 3D object detectors often neglect fundamental

As the most energetic explosions in the Universe, gamma-ray bursts (GRBs) are
commonly believed to be generated by relativistic jets. Recent observational
evidence suggests that the jets producing GRBs are likely to have a structured
nature. Some studies have suggested that non-axisymmetric structured jets may
be forme... | http://arxiv.org/abs/2310.20442v1 |
Information technology and telecommunications have rapidly permeated various
domains, resulting in a significant influx of data traversing the networks
between computers. Consequently, research of cyberattacks in computer systems
has become crucial for many organizations. Accordingly, recent cybersecurity
incidents hav... | http://arxiv.org/abs/2306.17508v1 |
In this work a new generalization of the theory of coupled modes for
non-periodic structured waveguide is presented. Based on a set of eigen waves
of a homogeneous periodic waveguide, a new basis of vector functions is
introduced that takes into account the non-periodicity of the waveguide.
Representing the total field... | http://arxiv.org/abs/2309.06280v1 |
The prevalence and strong capability of large language models (LLMs) present
significant safety and ethical risks if exploited by malicious users. To
prevent the potentially deceptive usage of LLMs, recent works have proposed
algorithms to detect LLM-generated text and protect LLMs. In this paper, we
investigate the ro... | http://arxiv.org/abs/2305.19713v2 |
Recently, there has been a growing focus and interest in applying machine
learning (ML) to the field of cybersecurity, particularly in malware detection
and prevention. Several research works on malware analysis have been proposed,
offering promising results for both academic and practical applications. In
these works,... | http://arxiv.org/abs/2309.13841v1 |
In the real world, data tends to follow long-tailed distributions w.r.t.
class or attribution, motivating the challenging Long-Tailed Recognition (LTR)
problem. In this paper, we revisit recent LTR methods with promising Vision
Transformers (ViT). We figure out that 1) ViT is hard to train with long-tailed
data. 2) ViT... | http://arxiv.org/abs/2302.14284v2 |
This work reports an efficient density-fitting implementation of the
density-based basis-set correction (DBBSC) method in the MOLPRO software. This
method consists in correcting the energy calculated by a wave-function method
with a given basis set by an adapted basis-set correction density functional
incorporating the... | http://arxiv.org/abs/2309.10390v2 |
Anomalously high nitrogen-to-oxygen abundance ratios [N/O] are observed in
globular clusters (GCs), among the field stars of the Milky Way (MW), and even
in the gas in a $z\approx 11$ galaxy. Using data from the APOGEE Data Release
17 and the Gaia Data Release 3, we present several independent lines of
evidence that mo... | http://arxiv.org/abs/2306.00060v1 |
We obtain a time-evolution operator for a forced optomechanical quantum
system using Lie algebraic methods when the normalized coupling between the
electromagnetic field and a mechanical oscillator, $G/\omega_m$, is not
negligible compared to one. Due to the forcing term, the interaction picture
Hamiltonian contains th... | http://arxiv.org/abs/2309.16087v2 |
In this article, we consider a class of the contact discontinuity for the
full compressible Euler equations, namely the entropy wave, where the velocity
is continuous across the interface while the density and the entropy can have
jumps. The nonlinear stability of entropy waves is a longstanding open problem
in multi-d... | http://arxiv.org/abs/2310.00209v2 |
Obtaining in-depth understanding of the relationships between the additive
manufacturing (AM) process, microstructure and mechanical properties is crucial
to overcome barriers in AM. In this study, database of metal AM was created
thanks to many literature studies. Subsequently meta-analyses on the data was
undertaken ... | http://arxiv.org/abs/2308.16621v1 |
Explicit results are derived using simple and exact methods for the joint and
marginal queue-length distributions for the M/M/c queue with two non-preemptive
priority levels. Equal service rates are assumed. Two approaches are
considered. One is based on numerically robust quadratic recurrence relations.
The other is b... | http://arxiv.org/abs/2309.09428v1 |
We show that each cluster seed in the augmentation variety is inhabited by an
embedded exact Lagrangian filling. This resolves the matter of surjectivity of
the map from Lagrangian fillings to cluster seeds. The main new technique to
produce these Lagrangian fillings is the construction and study of a quiver
with poten... | http://arxiv.org/abs/2308.00043v3 |
Currently, truss tomato weighing and packaging require significant manual
work. The main obstacle to automation lies in the difficulty of developing a
reliable robotic grasping system for already harvested trusses. We propose a
method to grasp trusses that are stacked in a crate with considerable clutter,
which is how ... | http://arxiv.org/abs/2309.17170v1 |
