Compressed Sensing over the Grassmann Manifold: A Unified Analytical Framework [PDF]
, 2009 It is well known that compressed sensing problems reduce to finding the sparse solutions for large under-determined systems of equations. Although finding the sparse solutions in general may be computationally difficult, starting with the seminal work of

Unsupervised fault diagnosis method based on iterative multi‐manifold spectral clustering
IET Collaborative Intelligent Manufacturing, Volume 1, Issue 2, Page 48-55, June 2019., 2019 Fault diagnosis is very important to the modern manufacturing system. As a powerful data‐driven method, machine learning (ML) has been widely used for fault diagnosis. However, a certain amount of labelled data is essential to most of the ML methods, which is not always available. In this study, an unsupervised fault diagnosis method based on iterative

Spaces of boundary values related to a multipoint version of the KP-hierarchy [PDF]
, 2004 In this paper one considers a finite number of points in the complex plane and various spaces of boundary values on circles surrounding these points. To this geometric configuration one associates a Grassmann manifolds that is shown to yield solutions ...

Ecological Research, Volume 40, Issue 5, September 2025.Industrial oil palm plantations threaten biodiversity in Southeast Asia, yet some native species are highly adaptable within these environments. Our study tracked four male leopard cats (Prionailurus javanensis) with GPS collars in the Kinabatangan floodplain, Sabah, revealing average home ranges of 8.60 km² (95% MCP) and 5.39 km² (95% a‐LoCoH), with ...

Integral Estimates for the Potential Operator on Differential Forms
International Journal of Analysis, Volume 2013, Issue 1, 2013., 2013 We develop the local inequalities with new weights for the potential operator applied to differential forms. We also prove the global weighted norm inequalities for the potential operator in averaging domains and explore applications of our new results.

Non-abelian gauge antisymmetric tensor fields
, 1992 We construct the theory of non-abelian gauge antisymmetric tensor fields, which generalize the standard Yang-MIlls fields and abelian gauge p-forms. The corresponding gauge group acts on the space of inhomogeneous differential forms and it is shown to be

African Journal of Ecology, Volume 63, Issue 3, April 2025.ABSTRACT Mammalian communities living in tropical forests, particularly those in ecological transition zones, are under constant threat from human activities. In many regions, baseline data on mammal richness, occupancy, detection probability and the environmental factors that influence these metrics are lacking.

Variable Exponent Spaces of Differential Forms on Riemannian Manifold
Journal of Function Spaces, Volume 2012, Issue 1, 2012., 2012 We introduce the Lebesgue space and the exterior Sobolev space for differential forms on Riemannian manifold M which are the Lebesgue space and the Sobolev space of functions on M, respectively, when the degree of differential forms to be zero. After discussing the properties of these spaces, we obtain the existence and uniqueness of weak solution for ...

Path Integral for the Dirac Equation [PDF]
, 1998 A c-number path integral representation is constructed for the solution of the Dirac equation. The integration is over the real trajectories in the continuous three-space and other two canonical pairs of compact variables controlling the spin and the ...
