Dataset for Narrowing the parameter space of collapse models with ultracold layered force sensors
<p>PSD - Original power spectral densities at different temperatures (in mK). For accounting the spectral leakage due to the FFT resolution, one has to remove the central 6 points. The columns are: frequency (Hz), value of PSD (Phi_0^2/Hz), PSD error (same units)</p> <p>Final data - Excel reporting the results of the PSD fits and that of the linear fit of B for the high temperatures. Final upper bound for the value of S_{F0}</p>
On The Development of Multidimensional Progenitor Models For Core-collapse Supernovae
<p>Eight multi-dimensional core-collapse supernova progenitor models from work, 'On The Development of Multidimensional Progenitor Models For Core-collapse Supernovae'. Works that utilize these progenitor models are required to cite article. All models are given at 424 seconds, less than a second before iron core-collapse. The 3D 4pi models were evolved to 424.31 seconds, the collapse time according to the 1D MESA model. All data are in FLASH4 format using the HDF5 data structure. </p>
Evolutionary rate and genetic load in an emblematic Mediterranean tree following an ancient and prolonged population collapse
Severe bottlenecks significantly diminish the amount of genetic diversity and the speed at which it accumulates (i.e. evolutionary rate). They further compromise the efficiency of natural selection to eliminate deleterious variants, which may reach fixation in the surviving populations. Consequently, expanding and adapting to new environments may pose a significant challenge when strong bottlenecks result in genetic pauperization. Herein, we surveyed the patterns of nucleotide diversity, molecular adaptation and genetic load across hundreds of loci in a circum-Mediterranean conifer (<i>Pinus pinea</i> L.) that represents one of the most extreme cases of genetic pauperization in widespread outbreeding taxa. We found very little genetic variation in both hypervariable non-coding (nuSSRs) and gene-coding loci, which translated into genetic diversity estimates one order of magnitude lower than those previously reported for pines. Such values were consistent with a strong population decline that began some ~1Ma. Comparisons with the related and partially parapatric maritime pine revealed reduced rates of adaptive evolution (<i>α</i> and <i>ω</i><sub>a</sub>) and a significant accumulation of genetic load. These did not appear to result from differences in mutation rates or linkage disequilibrium between the two species; instead they are the likely outcome of contrasting demographic histories affecting both the speed at which these taxa accumulate genetic diversity, and the global efficacy of selection. Future studies, and programs for conservation and management, should thus start testing for the effects of genetic load on fitness and integrating such effects into predictive models.
