The secular equation for elastic surface waves under non standard boundary conditions of impedance type: A perspective from linear algebra
The study of elastic surface waves under impedance boundary conditions has become an intensive field of research due to their potential to model a wide range of problems. However, even when the secular equation, which provides the speed of the surface wave, can be explicitly derived, the analysis is limited to specific cases due to its cumbersome final expression. In this work, we present an alternative method based on linear algebra tools, to deal with the secular equation for surface waves in…

Modeling the secular evolution of embedded protoplanetary discs
Context: Protoplanetary discs are known to form around nascent stars from their parent molecular cloud as a result of angular momentum conservation. As they progressively evolve and dissipate, they also form planets. While a lot of modeling efforts have been dedicated to their formation, the question of their secular evolution, from the so-called class 0 embedded phase to the class II phase where discs are believed to be isolated, remains poorly understood. Aims: We aim to explore the evolution…

How allowing abortion for secular reasons means allowing it for religious reasons
(RNS) — States’ abortion laws may not be ‘underinclusive.’

Why changing U.S. demographics aren’t affecting the political balance of power
Yes, the number of secular Americans grew, and those #secular voters began to identify more strongly with the #Democrats.
But at the same time, #religious

Why changing U.S. demographics aren't affecting the political balance of power
Even as the country has become more racially and ethnically diverse and religious attendance has declined, the relative size of the two big political-party coalitions has stayed almost identical.

Cylindrical Gravitational Waves in Einstein-Aether Theory
Along the lines of the Einstein-Rosen wave equation of General Relativity (GR), we derive a gravitational wave equation with cylindrical symmetry in the Einstein-aether (EA) theory. We show that the gravitational wave in the EA is periodic in time for both the metric functions $Ψ(r,t)$ and $H(r,t)$. However, in GR, $Ψ(r,t)$ is periodic in time, but $H(r,t)$ is semi-periodic in time, having a secular drifting in the wave frequency. The evolution of wave pulses of a given width is entirely diff…

Non-evolutionary effects on Period change in Magellanic Cepheids I. New binary systems revealed from Light Travel Time Effect
Period change studies give a window to probe into the evolution and dynamics of Cepheids. While evolutionary period changes have been well studied both observationally and theoretically, non-evolutionary period changes lack a systematic and quantitative description. The overall objective is to have a quantitative understanding of the full picture of non-evolutionary period changes in Cepheids, to develop a formalism to disentangle it from the secular evolutionary period change. In the first par…
