A cosmological scenario in which the onset of neutrino free streaming in the
early Universe is delayed until close to the epoch of matter-radiation equality
has been shown to provide a good fit to some cosmic microwave background (CMB)
data, while being somewhat disfavored by Planck CMB polarization data. To
clarify th... | http://arxiv.org/abs/2309.03941v2 |
A major challenge with off-road autonomous navigation is the lack of maps or
road markings that can be used to plan a path for autonomous robots. Classical
path planning methods mostly assume a perfectly known environment without
accounting for the inherent perception and sensing uncertainty from detecting
terrain and ... | http://arxiv.org/abs/2309.08814v1 |
In this study, we investigate a recent finding based on strong lensing
observations, which suggests that the sub-halos observed in clusters exhibit
greater compactness compared to those predicted by $\Lambda$CDM simulations. To
address this discrepancy, we performed a comparative analysis by comparing the
cumulative ma... | http://arxiv.org/abs/2309.06187v1 |
Hydrogenated amorphous silicon (a-Si:H) is a material having an intrinsically
high radiation hardness that can be deposited on flexible substrates like
Polyimide. For these properties a-Si:H can be used for the production of
flexible sensors. a-Si:H sensors can be successfully utilized in dosimetry,
beam monitoring for... | http://arxiv.org/abs/2310.00495v1 |
We study a susceptible-infected-recovered (SIR) epidemic model on a network
of $n$ interacting subpopulations. We analyze the transient and asymptotic
behavior of the infection dynamics in each node of the network. In contrast to
the classical scalar epidemic SIR model, where the infection curve is known to
be unimodal... | http://arxiv.org/abs/2309.14583v2 |
Navigating robots through unstructured terrains is challenging, primarily due
to the dynamic environmental changes. While humans adeptly navigate such
terrains by using context from their observations, creating a similar
context-aware navigation system for robots is difficult. The essence of the
issue lies in the acqui... | http://arxiv.org/abs/2310.00481v3 |
The conditional generative adversarial rainfall model "cGAN" developed for
the UK \cite{Harris22} was trained to post-process into an ensemble and
downscale ERA5 rainfall to 1km resolution over three regions of the USA and the
UK. Relative to radar data (stage IV and NIMROD), the quality of the forecast
rainfall distri... | http://arxiv.org/abs/2309.15689v1 |
Deep reinforcement learning agents for continuous control are known to
exhibit significant instability in their performance over time. In this work,
we provide a fresh perspective on these behaviors by studying the return
landscape: the mapping between a policy and a return. We find that popular
algorithms traverse noi... | http://arxiv.org/abs/2309.14597v3 |
Electrostatic waves play a critical role in nearly every branch of plasma
physics from fusion to advanced accelerators, to astro, solar, and ionospheric
physics. The properties of planar electrostatic waves are fully determined by
the plasma conditions, such as density, temperature, ionization state, or
details of the ... | http://arxiv.org/abs/2309.06193v2 |
In this work, we introduce the concept of complex text style transfer tasks,
and constructed complex text datasets based on two widely applicable scenarios.
Our dataset is the first large-scale data set of its kind, with 700 rephrased
sentences and 1,000 sentences from the game Genshin Impact. While large
language mode... | http://arxiv.org/abs/2309.10929v1 |
We estabish rigorous estimates for the Hausdorff dimension of the spectra of
Laplacians associated to Sierpi\'nski lattices and infinite Sierpi\'nski
gaskets and other post-critically finite self-similar sets. | http://arxiv.org/abs/2308.00185v1 |
Federated Learning (FL) has been successfully adopted for distributed
training and inference of large-scale Deep Neural Networks (DNNs). However,
DNNs are characterized by an extremely large number of parameters, thus,
yielding significant challenges in exchanging these parameters among
distributed nodes and managing t... | http://arxiv.org/abs/2309.06805v1 |
