In 1956, Alder conjectured that the number of partitions of n into parts differing by at least d is greater than or equal to that of partitions of n into parts identical with +/-1 (mod d+3) for d > or = 4. In 1971, Andrews proved that the conjecture holds for d = 2r-1, r > or = 4. We sketch a proof of the conjecture for all d > or = 32.

Antibiotics are extensively used to manage human, animal and plant ailments caused by microbial infections. However, rampant use of antibiotics has led to the development of antibiotic resistance, which is a public health concern. The development of antibiotic resistance is significantly influenced by agro-ecosystems.

Graph Neural Networks (GNNs) have achieved remarkable success in various graph mining tasks by aggregating information from neighborhoods for representation learning. The success relies on the homophily assumption that nearby nodes exhibit similar behaviors, while it may be violated in many real-world graphs. Recently, heterophilous graph neural networks (HeterGNNs) have attracted increasing attention by modifying the neural message passing schema for heterophilous neighborhoods.

Objectives: To evaluate the antifungal activity of extracts and compounds from against clinically relevant species, notably , and investigate possible mechanisms of action using electron microscopy and techniques.
Methods: Extracts and fractions of were obtained through turboextraction and partitioning, while the isolated compounds were previously purified. The ethyl acetate fraction (EAF) was characterized by HPLC.

Although separation is entropically unfavourable, it is often essential for our life. The separation of very similar macromolecules such as deoxyribonucleic acids (DNAs) and their single nucleotide variants is difficult but holds great advantage for the progress of life science. Here we report that a particular liquid-liquid phase separation (LLPS) at a solid-liquid interface led to the partitioning of DNAs with nearly identical structures.
