“All five nucleobases used to construct both DNA and RNA,
along with phosphates,
have already been found in the Bennu samples
brought to Earth by OSIRIS-REx,”
said Yoshihiro Furukawa.
“The new discovery of ribose means that all of the components to form the molecule RNA are present in Bennu.”

Oracle-based Uniform Sampling from Convex Bodies
We propose new Markov chain Monte Carlo algorithms to sample a uniform distribution on a convex body $K$. Our algorithms are based on the Alternating Sampling Framework/proximal sampler, which uses Gibbs sampling on an augmented distribution and assumes access to the so-called restricted Gaussian oracle (RGO). The key contribution of this work is the efficient implementation of RGO for uniform sampling on $K$ via rejection sampling and access to either a projection oracle or a separation oracle…

Simplicial Perspectives on (Pseudo) Effect Algebras
The study of Frobenius algebras in the category $\mathbf{Rel}$ via their nerve functor into simplicial sets has been introduced recently. In this article, we focus on the particular case of effect algebras and pseudo effect algebras and investigate these using tools from combinatorial topology. To each (pseudo) effect algebra $E$, we associate a simplicial set with edge marking $N(E)$, called an $ε$-simplicial set, and analyze its structural properties. In particular, we provide certain charac…

(Injective) facet-complexity between simplicial complexes
We present the notion of facet-complexity, $\text{C}(\mathsf{L};\mathsf{K})$, for two simplicial complexes $\mathsf{L}$ and $\mathsf{K}$, along with basic results for this numerical invariant. This invariant $\text{C}(\mathsf{L};\mathsf{K})$ quantifies the \aspas{complexity} of the following question: When does there exist a facet simplicial map $\mathsf{L}\to \mathsf{K}$? A facet simplicial map is a simplicial map that preserves non-unitary facets. Likewise, we introduce the notion of injectiv…
