Black-capped chickadee (Poecile atricapillus) vocalisations remain plastic throughout their lifespans. Although fledglings employ vocal plasticity to refine their vocalisations through the use of tutor mimicry, adults employ vocal plasticity to create unique population dialects. Vocal convergence is one mechanism by which flockmates' vocalisations become increasingly similar to each other and distinct from the calls of other flocks.

Observation of Ɛ-AlKeggin-Oligonucleotide Complexes in Analytical Sample Solutions.

J Pharm Sci

January 2025

Ionis Pharmaceuticals, Inc., 2855 Gazelle Ct., Carlsbad, CA 92010. Electronic address:

Complexes formed between aluminum cluster molecules that adopt a Ɛ-Al-Keggin structure and antisense oligonucleotides were observed as new impurity peaks during drug product stability testing. The Ɛ-Al-Keggin molecules were determined to be artifacts of the analysis, originating from contact between antisense oligonucleotide drug product solution and aluminum weigh boats used to prepare the analytical sample solutions The presence of the Ɛ-Al-Keggin molecules was confirmed through synthesis of the Keggin molecule through an established route and subsequent spiking studies. Binding affinity studies revealed that the Ɛ-Al-Keggin bound to oligonucleotide sequences of various lengths (10 to 20 bases) and base compositions, though there is some evidence for preferential binding to 5-methylcytosine-containing sequences.

Division of Nephrology, Department of Medicine, Vagelos College of Physicians & Surgeons, Columbia University, New York, NY; Department of Epidemiology, Mailman School of Public Health, Columbia University, New York, NY.

There is substantial variation in access to transplantation across the United States that is not entirely explained by the availability of donor organs. Barriers to transplantation and variation in care among patients with end-stage organ disease exist prior to patients' placement on a transplant waiting list as well as following waitlist placement. However, there are currently no national data available to examine rates and variations in key care processes related to pre-listing, including transplant referral, evaluation, or candidate selection.

There are powerful tools for modelling swarms that have strong spatial structures like flocks of birds, schools of fish and formations of drones, but relatively little work on developing formalisms for other swarm structures like hub-based colonies doing foraging, maintaining a nest or selecting a new nest site. We present a method for finding low-dimensional representations of swarm state for simulated homogeneous hub-based colonies solving the best-of-N problem. The embeddings are obtained from latent representations of convolution-based graph neural network architectures and have the property that swarm states which have similar performance have very similar embeddings.
