Efficient Evaluation of Matrix Polynomials beyond the Paterson–Stockmeyer Method
Mathematics, 2021 Recently, two general methods for evaluating matrix polynomials requiring one matrix product less than the Paterson–Stockmeyer method were proposed, where the cost of evaluating a matrix polynomial is given asymptotically by the total number of matrix ...

MFCosface: A Masked-Face Recognition Algorithm Based on Large Margin Cosine Loss
Applied Sciences, 2021 The world today is being hit by COVID-19. As opposed to fingerprints and ID cards, facial recognition technology can effectively prevent the spread of viruses in public places because it does not require contact with specific sensors.

On the quasi-Fredholm and Saphar spectrum of strongly continuous Cosine operator function
Moroccan Journal of Pure and Applied Analysis, 2021 Let (C(t))t∈ be a strongly continuous cosine family and A be its infinitesimal generator. In this work, we prove that, if C(t) – coshλt is Saphar (resp. quasi-Fredholm) operator and λt /∉iπ, then A – λ2 is also Saphar (resp.

Analysis of ultradian rest-activity rhythms using locomotor activity in mice [PDF]
Kosin Medical Journal, 2022 Background Locomotor activity in mice may have an ultradian rest-activity rhythm. However, to date, no study has shown how locomotor activity can be explained statistically using fitted cosine curves.

Composite Cosine Transforms [PDF]
Mathematika, 2005 The cosine transforms of functions on the unit sphere play an important role in convex geometry, the Banach space theory, stochastic geometry and other areas. Their higher-rank generalization to Grassmann manifolds represents an interesting mathematical object useful for applications.

An Intriguing Interpretation of 1D and 2D Non-Diffracting Modes in Cosine Profile
Photonics, 2023 We provide a simple analysis based on ray optics and Dirac notation for 1D (one-dimensional) and 2D (two-dimensional) non-diffracting modes in the cosine profile, which are often called Cosine beams. We explore various kinds of structured modes formed by

Spectral Theory For Strongly Continuous Cosine
Concrete Operators, 2021 Let (C(t))t∈ℝ be a strongly continuous cosine family and A be its infinitesimal generator. In this work, we prove that, if C(t) – cosh λt is semi-Fredholm (resp.
