On the quasi-Fredholm and Saphar spectrum of strongly continuous Cosine operator function
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]
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.

Digital shaping methods for nuclear pulse signal based on cosine function
BackgroundCosine function shaping (or cos shaping) is used to digitally shape nuclear pulse signals, as the shaping method is simple and has high operability and flexibility.PurposeThis study aims to explore different cosine shaping methods of nuclear ...

ON COSINE FAMILIES CLOSE TO SCALAR COSINE FAMILIES [PDF]
We prove that if two normed-algebra-valued cosine families indexed by a single Abelian group, of which one is bounded and comprised solely of scalar elements of the underlying algebra, differ in norm by less than$1$uniformly in the parametrising index, then these families coincide.

Spectral Theory For Strongly Continuous Cosine
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.

An Intriguing Interpretation of 1D and 2D Non-Diffracting Modes in Cosine Profile
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

Is Cosine-Similarity of Embeddings Really About Similarity? [PDF]
Cosine-similarity is the cosine of the angle between two vectors, or equivalently the dot product between their normalizations. A popular application is to quantify semantic similarity between high-dimensional objects by applying cosine-similarity to a ...

A comprehensive survey of sine cosine algorithm: variants and applications
Sine Cosine Algorithm (SCA) is a recent meta-heuristic algorithm inspired by the proprieties of trigonometric sine and cosine functions. Since its introduction by Mirjalili in 2016, SCA has attracted great attention from researchers and has been widely ...
