Estimation of growth parameters for the exploited sea cucumber Holothuria arguinensis from South Portugal [PDF]
, 2018 Understanding how species grow is critical for choosing appropriate fisheries management strategies. Sea cucumbers shrink during periods of aestivation and have naturally flaccid bodies that make measuring growth difficult.

Pulsational frequency and amplitude modulation in the δ Sct star KIC 7106205 [PDF]
, 2014 Analysis of the Kepler δ Sct star KIC 7106205 showed amplitude modulation in a single pressure mode, whilst all other pressure and gravity modes remained stable in amplitude and phase over the 1470 d length of the data set.

Analysis of vocal communication in the genus Falco
Scientific Reports, 2023 Vocal learning occurs in three clades of birds: hummingbirds, parrots, and songbirds. Examining vocal communication within the Falconiformes (sister taxon to the parrot/songbird clade) may offer information in understanding the evolution of vocal ...

Mixture of Time-Dependent Growth Models with an Application to Blue Swimmer Crab Length-Frequency Data [PDF]
Biometrics, 2016 Summary Understanding how aquatic species grow is fundamental in fisheries because stock assessment often relies on growth dependent statistical models. Length-frequency-based methods become important when more applicable data for growth model estimation are either not available or very expensive.

Numerical simulation of bubble generation in a T-junction [PDF]
, 2012 We present a numerical study of the formation of mini-bubbles in a 2D T-junction by means of the fluid dynamics numerical code JADIM. Numerical simulations were carried out for different flow conditions, giving rise to results on the behavior of bubble ...

On the Existence and Uniqueness of Global Solutions for the KdV Equation with Quasi-Periodic Initial Data [PDF]
, 2015 We consider the KdV equation $$ \partial_t u +\partial^3_x u +u\partial_x u=0 $$ with quasi-periodic initial data whose Fourier coefficients decay exponentially and prove existence and uniqueness, in the class of functions which have an expansion with ...
