Ligand binding represses bacterial histidine kinase activity by inhibiting its dimerization
The FEBS Journal, EarlyView.PdtaS is a kinase in the pathogen Mycobacterium tuberculosis that senses copper and nitric oxide and controls virulence gene expression, but how the kinase senses these compounds was unclear. We show that PdtaS is active as a dimer with each monomer phosphorylating the other in trans.

Local SGD Converges Fast and Communicates Little [PDF]
Mini-batch stochastic gradient descent (SGD) is state of the art in large scale distributed training. The scheme can reach a linear speedup with respect to the number of workers, but this is rarely seen in practice as the scheme often suffers from large ...

Comparing deep learning models for butterfly and moth (Lepidoptera) species identification
Insect Conservation and Diversity, EarlyView.Deep learning models open new possibilities for the processing of image‐based species records. We used high‐performance computing to compare 40 models for butterfly and moth species identification based on a citizen science dataset with over 500,000 images of 162 species.

Spectral Transforms as a Tool to Optimize Digital Phenotyping in Biological Images
Journal of Animal Breeding and Genetics, EarlyView.ABSTRACT Modern livestock breeding has mastered genotyping. Genome‐wide association studies, genomic selection, and SNP arrays enable genetic merit prediction at lower cost. However, phenotyping remains the bottleneck, as manual measurement is slow, expensive, subjective, and unable to capture spatial or temporal trait organization. Digital phenotyping

Marine migration influences mercury accumulation in anadromous Arctic char (Salvelinus alpinus)
Journal of Fish Biology, EarlyView.Abstract Mercury (Hg) is a globally distributed toxic metal present in northern natural environments that biomagnifies in food webs and bioaccumulates in apex predator fish, such as Arctic char (Salvelinus alpinus)—an iteroparous species with a circumpolar distribution. Arctic char exhibit a variety of life history types, with the migrating, anadromous

Heavy-Tail Phenomenon in Decentralized SGD
International audienceRecent theoretical studies have shown that heavy-tails can emerge in stochastic optimization due to `multiplicative noise', even under surprisingly simple settings, such as linear regression with Gaussian data.
