This article describes modal analysis of acoustic waves in the human vocal tract while the subject is pronouncing [o]. The model used is the wave equation in three dimensions, together with physically relevant boundary conditions. The geometry is reconstructed from anatomical MRI data obtained by other researchers. The computations are carried out using the finite element method. The model is validated by comparing the computed modes with measured data.

Article Synopsis
  • The study reveals that laser-assisted dynamic interference in electron spectra can be experimentally observed using attosecond pulse trains, demonstrating fine interference patterns smaller than the energy of individual laser photons.
  • Theoretical simulations align with experimental findings, utilizing methods like the time-dependent Schrödinger equation and strong-field approximation to support the results.
  • Further analysis emphasizes the significance of phase variations in electron wave packets, showing that the manipulation of electron behavior in the continuum is achievable through advanced multicolor laser techniques controlled at attosecond timescales.

The Lie group method is a powerful technique for obtaining analytical solutions for various nonlinear differential equations. This study aimed to explore the behavior of nonlinear elastic wave equations and their underlying physical properties using Lie group invariants. We derived eight-dimensional symmetry algebra for the (3+1)-dimensional nonlinear elastic wave equation, which was used to obtain the optimal system.

We consider turbulence of waves interacting weakly via four-wave scattering (sea waves, plasma waves, spin waves, etc.). In the first order in the interaction, a closed kinetic equation has stationary solutions describing turbulent cascades.

Individuals' health literacy (HL) is positively associated with healthy behaviors and global cognitive functioning. Current evidence also suggests that physical activity may prevent or delay cognitive decline and dementia. This study examines the potential mediating role of physical activity in the association between HL and cognition in a population-based sample of adults aged 58+ in Switzerland.

Photonic design is a process of mathematical optimization of a desired objective (beam formation, mode conversion, etc.) subject to the constraint of Maxwell's equations. Finding the optimal design is challenging: Generically, these problems are highly nonconvex and finding global optima is NP hard.
