Don't forget the electrons: extending moderately-sized nuclear networks for multidimensional hydrodynamic codes
We present here an extended nuclear network, with 90 species, designed for being coupled with hydrodynamic simulations, which includes neutrons, protons, electrons, positrons, and the corresponding neutrino and anti-neutrino emission. This network is also coupled with temperature, making it extremely robust and, together with its size, unique of its kind. The inclusion of electron captures on free protons makes the network very appropriate for multidimensional studies of Type Ia supernova explo…

Bayesian Nonparametric Inference for "Species-sampling" Problems
Given an observed sample from a population of individuals belonging to species, "species-sampling" problems (SSPs) call for estimating some features of the unknown species composition of additional unobservable samples from the same population. Within SSPs, the problems of estimating coverage probabilities, the number of unseen species and coverages of prevalences have emerged in the past three decades for being the subject of numerous methodological and applied works, mostly in biological scie…

Freakin' NASA can maintain their Voyagers for decades and ship firmware updates to them despite being VEEEEEERY far away, yet I'll 100% have to upgrade at least one computer / mobile device of mine within next 10 years due to lack of software support.
Where did we make a mistake as a species.

A Comparison of Joint Species Distribution Models for Percent Cover Data
1. Joint species distribution models (JSDMs) have gained considerable traction among ecologists over the past decade, due to their capacity to answer a wide range of questions at both the species- and the community-level. The family of generalized linear latent variable models in particular has proven popular for building JSDMs, being able to handle many response types including presence-absence data, biomass, overdispersed and/or zero-inflated counts. 2. We extend latent variable models to h…

All Thresholds Barred: Direct Estimation of Call Density in Bioacoustic Data
Passive acoustic monitoring (PAM) studies generate thousands of hours of audio, which may be used to monitor specific animal populations, conduct broad biodiversity surveys, detect threats such as poachers, and more. Machine learning classifiers for species identification are increasingly being used to process the vast amount of audio generated by bioacoustic surveys, expediting analysis and increasing the utility of PAM as a management tool. In common practice, a threshold is applied to classi…

The inhomogeneous $t$-PushTASEP and Macdonald polynomials
We study a multispecies $t$-PushTASEP system on a finite ring of $n$ sites with site-dependent rates $x_1,\dots,x_n$. Let $λ=(λ_1,\dots,λ_n)$ be a partition whose parts represent the species of the $n$ particles on the ring. We show that for each composition $η$ obtained by permuting the parts of $λ$, the stationary probability of being in state $η$ is proportional to the ASEP polynomial $F_η(x_1,\dots,x_n; q,t)$ at $q=1$; the normalizing constant (or partition function) is the Macdonald…

Coupling in situ and remote sensing data to assess $α$- and $β$-diversity over biogeographic gradients
The challenges presented by climate change are escalating and pose significant threats to global biodiversity, which in turn increases the risk of species extinctions. Therefore, meticulous monitoring efforts are necessary to mitigate the consequential impacts on both human well-being and environmental equilibrium. Biodiversity mapping is pivotal for establishing conservation priorities, often accomplished by assessing alpha, beta, and gamma diversity levels. Two main data sources, in situ and …

Preparation of tautomer-pure molecular beams by electrostatic deflection
Tautomers are ubiquitous throughout chemistry, and typically considered inseparable in solution. Yet (bio)chemical activity is highly tautomer specific, with common examples being the amino and nucleic acids. While tautomers exist in an equilibrium in solution, in the cold environment of a molecular beam the barrier to tautomerization is typically much too high for interconversion, and tautomers can be considered separate species. Here we demonstrate the separation of tautomers and production o…

Allowing Growing Dimensional Binary Outcomes via the Multivariate Probit Indian Buffet Process
There is a rich literature on infinite latent feature models, with much of the focus being on the Indian Buffet Process (IBP). The current literature focuses on the case in which latent features are generated independently, so that there is no within-sample dependence in which features are selected. Motivated by ecology applications in which latent features correspond to which species are discovered in a sample, we propose a new class of dependent infinite latent feature models. Our constructio…
