P.03 Local Pulse Wave Velocity Estimation using a Double Gaussian Propagation Model

open access: yesArtery Research, 2020
Background: Pulse wave velocity (PWV) is an established marker of arterial stiffness [1]. Local PWV estimates, however, are affected by confluence of incident and reflected waves, biasing the spatiotemporal propagation of the systolic foot (SF) in the ...

Is $$d^*(2380)$$ d ∗ ( 2380 ) a compact hexaquark state?

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
The most fascinating dibaryon in the non-strange quark sector is $$d^*(2380)$$ d ∗ ( 2380 ) , which was reported by WASA-at-COSY Collaboration and confirmed by A2@MAMI Collaboration. The reported mass and decay width are $$M\approx 2.37$$ M ≈ 2.37 GeV, $$

A Novel Phase Noise Suppression Scheme Utilizing Gaussian Wavelet Basis Expansion for PDM CO-OFDM Superchannel

open access: yesIEEE Photonics Journal, 2020
In this paper, we propose a novel Gaussian wavelet basis expansion-based phase noise suppression scheme for polarization-division-multiplexing (PDM) coherent optical orthogonal frequency division multiplexing (CO-OFDM) superchannel.

A simple mathematical model of gradual Darwinian evolution: Emergence of a Gaussian trait distribution in adaptation along a fitness gradient [PDF]

open access: yes, 2013
We consider a simple mathematical model of gradual Darwinian evolution in continuous time and continuous trait space, due to intraspecific competition for common resource in an asexually reproducing population in constant environment, while far from ...
