Assessing the Feasibility of Internet-Sourced Video for Automatic Cattle Lameness Detection [PDF]

arXiv
Cattle lameness is often caused by hoof injuries or interdigital dermatitis, leads to pain and significantly impacts essential physiological activities such as walking, feeding, and drinking. This study presents a deep learning-based model for detecting cattle lameness, sickness, or gait abnormalities using publicly available video data.

Generic jet evaluation transversality of contact instantons against contact distribution [PDF]

arXiv
For a given coorientable contact manifold $(M,\Xi)$ with contact distribution $\Xi$, we consider its contact forms $\lambda$ with $\ker \lambda = \Xi$, and the associated contact triads $(M,\lambda, J)$. For a generic choice of contact form $\lambda$, we prove the (0-jet) the interior and boundary evaluation maps, and the 1-jet transversality of ...

An improved point-to-surface contact algorithm with penalty method for peridynamics [PDF]

arXiv
It is significantly challenging to obtain accurate contact forces in peridynamics (PD) simulations due to the difficulty of surface particles identification, particularly for complex geometries. Here, an improved point-to-surface contact model is proposed for PD with high accuracy.

Connected sums of Brieskorn contact $5$-spheres [PDF]

arXiv
In dimension $5$, the contact connected sum of Brieskorn contact spheres is, in general, not a Brieskorn contact sphere.

Contact embeddings of 3-dimensional contact groups [PDF]

arXiv
A 3-dimensional contact group is a 3-dimensional Lie group endowed with a left-invariant contact structure. Making use of techniques from Riemannian geometry, we prove that any simply connected 3-dimensional contact group not isomorphic to SU(2) satisfies a unique factorization property. As an application, we develop a method to construct embeddings of
