Comparative Demography of Five Holocentridae Species from American Samoa

Fishes
This study provides the first insights into the age-based life histories of five Holocentridae species (soldierfish and squirrelfish) from American Samoa: Myripristis amaena, M. berndti, M. murdjan, Sargocentron spiniferum, and S. tiere.

Propagation reversal on trees in the large diffusion regime

Results in Applied Mathematics
In this work we study travelling wave solutions to bistable reaction–diffusion equations on bi-infinite k-ary trees in the continuum regime where the diffusion parameter is large.

Dynamics of large-amplitude geostrophic flows over bottom topography [PDF]

Nonlinear Processes in Geophysics, 1997
We examine the interaction of near-surface and near- bottom flows over bottom topography. A set of asymptotic equations for geostrophic currents in a three-layer fluid is derived.

The Centrifugal Instability of a Slender Rotating Cone

Journal of Algorithms & Computational Technology, 2012
In this study, we provide a mathematical description of the onset of counter-rotating circular vortices observed for a family of slender rotating cones (of half-angles 15° or less) in quiescent fluid. In particular, we apply appropriate scalings in order

Optimization of Schwinger pair production in colliding laser pulses

Physics Letters B, 2014
Recent studies of Schwinger pair production have demonstrated that the asymptotic particle spectrum is extremely sensitive to the applied field profile.

A study on the geometric configuration and stability of wormholes in symmetric teleparallel gravity influenced by dark energy and rotational velocity profiles

European Physical Journal C: Particles and Fields
This study explores the characteristics of wormhole geometries within the framework of symmetric teleparallel gravity, specifically $$\mathcal {F}(\mathcal {Q})$$ F ( Q ) gravity.

Finite element analysis of lateral pressure variations in square steel silos considering parametric impacts

Scientific Reports
This study develops and validates a 3-D finite-element model for lateral pressures in square, flat-bottomed steel silos, challenging the applicability of conventional design methods. The model, using Mohr–Coulomb for wheat and surface-to-surface contact,

Long-lived quasinormal modes in the Euler-Heisenberg electrodynamics

Physics Letters B
Using the precise Leaver method and time-domain integration, we analyze the quasinormal modes and late-time behavior of massive neutral and charged scalar fields in the background of a charged, asymptotically flat black hole in the presence of Euler ...

Spectral stability of undercompressive shock profile solutions of a modified KdV-Burgers equation

Electronic Journal of Differential Equations, 2007
It is shown that certain undercompressive shock profile solutions of the modified Korteweg-de Vries-Burgers equation $$ partial_t u + partial_x(u^3) = partial_x^3 u + alpha partial_x^2 u, quad alpha geq 0 $$ are spectrally stable when $alpha$ is ...
