A mixed sine cosine butterfly optimization algorithm for global optimization and its application
This paper proposes a hybrid sine cosine butterfly optimization algorithm (m-SCBOA), in which a modified butterfly optimization algorithm is combined with sine cosine algorithm to achieve superior exploratory and exploitative search capabilities.

The New Advanced Telescope for High ENergy Astrophysics (NewAthena) will be the largest space-based X-ray observatory ever built. It will have an effective area above 1.1 m2 at 1 keV, which corresponds to a polished mirror surface of about 300 m2 due to ...

Dynamical Analysis of Two-Dimensional Memristor Cosine Map
Research on discrete memristor models applied to discrete maps deserves more in-depth discussion. In this paper, a continuous memristor is introduced and the discrete memristor model is obtained by the forward Eulerian difference algorithmic ...

Status of the COSINE Experiment
The COSINE collaboration is preparing to test an annual modulation signal of the DAMA/LIBRA experiment unambiguously, with a 4$\times$2 array of low-background NaI(Tl) crystals at the Yangyang Underground Laboratory, South Korea.

COSINE-100 and DAMA/LIBRA-phase2 in WIMP effective models [PDF]
Assuming a standard Maxwellian for the WIMP velocity distribution, we obtain the bounds from null WIMP search results of 59.5 days of COSINE-100 data on the DAMA/LIBRA-phase2 modulation effect within the context of the non-relativistic effective theory ...

The Discrete Cosine Transform on Triangles [PDF]
The discrete cosine transform is a valuable tool in analysis of data on undirected rectangular grids, like images. In this paper it is shown how one can define an analogue of the discrete cosine transform on triangles. This is done by combining algebraic signal processing theory with a specific kind of multivariate Chebyshev polynomials.

Status of the COSINE-100 Experiment
Presently a number of experiments are operating to search for the WIMP, a dark matter candidate. Among these experiments, DAMA/LIBRA claims to observe an annually modulated WIMP signal, while other experiments, using different technologies and target ...

ABSTRACT Background Emerging evidence suggests that low‐frequency neural oscillations are dynamically regulated by consciousness levels, with the recovery of low cortical activity potentially serving as a neurophysiological substrate for conscious emergence. Targeted enhancement of these low‐frequency rhythms in patients with disorders of consciousness
