In this paper, we introduce techniques for animating explosions and their
effects. The primary effect of an explosion is a disturbance that causes a
shock wave to propagate through the surrounding medium. This disturbance
determines the behavior of nearly all other secondary effects seen in
explosions. We simulate the ... | http://arxiv.org/abs/2303.10541v1 |
Reconstructing the 3D shape of an object from a single RGB image is a
long-standing and highly challenging problem in computer vision. In this paper,
we propose a novel method for single-image 3D reconstruction which generates a
sparse point cloud via a conditional denoising diffusion process. Our method
takes as input... | http://arxiv.org/abs/2302.10668v2 |
Secure software engineering is crucial but can be time-consuming; therefore,
methods that could expedite the identification of software weaknesses without
reducing the process efficacy would benefit the software engineering industry
and thus benefit modern life. This research focuses on finding an efficient
machine lea... | http://arxiv.org/abs/2308.05558v1 |
Accurate quasar classifications and redshift measurements are increasingly
important to precision cosmology experiments. Broad absorption line (BAL)
features are present in 15-20\% of all quasars, and these features can
introduce systematic redshift errors, and in extreme cases produce
misclassifications. We quantitati... | http://arxiv.org/abs/2304.05855v1 |
The exact renormalization group (ERG) is a powerful tool for understanding
the formal properties of field theories. By adapting generalized ERG schemes to
the flow of wavefunctionals, we obtain a large class of continuous unitary
networks, a special case of which includes a class of Gaussian continuous
Multi-scale Reno... | http://arxiv.org/abs/2301.09669v2 |
A kind of combinatorial map, called arrow presentation, is proposed to encode
the data of the oriented closed polyhedral complexes $\Sigma$ on which the Hopf
algebraic Kitaev model lives. We develop a theory of arrow presentations which
underlines the role of the dual of the double $\mathcal{D}(\Sigma)^*$ of
$\Sigma$ a... | http://arxiv.org/abs/2302.08027v6 |
Electromagnetic waves possessing orbital angular momentum (OAM) are powerful
tools for applications in optical communications, new quantum technologies and
optical tweezers. Recently, they have attracted growing interest since they can
be harnessed to detect peculiar helical dichroic effects in chiral molecular
media a... | http://arxiv.org/abs/2310.11773v1 |
Recent advancements in GANs and diffusion models have enabled the creation of
high-resolution, hyper-realistic images. However, these models may misrepresent
certain social groups and present bias. Understanding bias in these models
remains an important research question, especially for tasks that support
critical deci... | http://arxiv.org/abs/2302.11562v1 |
In scholarly documents, figures provide a straightforward way of
communicating scientific findings to readers. Automating figure caption
generation helps move model understandings of scientific documents beyond text
and will help authors write informative captions that facilitate communicating
scientific findings. Unli... | http://arxiv.org/abs/2306.03491v1 |
Lithium-rich giant stars are rare and their existence challenges our
understanding of stellar structure and evolution. We profit from the
high-quality sample gathered with HARPS and UVES, in order to search for
Li-rich giants and to identify the Li enrichment mechanisms responsible. We
derive stellar parameters for 247... | http://arxiv.org/abs/2303.16124v1 |
We address the need to generate faithful explanations of "black box" Deep
Learning models. Several tests have been proposed to determine aspects of
faithfulness of explanation methods, but they lack cross-domain applicability
and a rigorous methodology. Hence, we select an existing test that is model
agnostic and is we... | http://arxiv.org/abs/2306.13682v1 |
