Domain walls are quasi-one-dimensional topological defects in ferroic materials, which can harbor emergent functionalities. In the case of ferroelectric domain wall (FEDW) devices, an exciting frontier has emerged: memristor-based information storage and processing approaches. Memristor solid-state FEDW devices presented thus far, however predominantly utilize a complex network of domain walls to achieve the desired regulation of density and charge state.

MixtureFinder: Estimating DNA mixture models for phylogenetic analyses.

Mol Biol Evol

December 2024

Ecology and Evolution, Research School of Biology, College of Science, Australian National University, Canberra, ACT 2600, Australia.

In phylogenetic studies, both partitioned models and mixture models are used to account for heterogeneity in molecular evolution among the sites of DNA sequence alignments. Partitioned models require the user to specify the grouping of sites into subsets, and then assume that each subset of sites can be modelled by a single common process. Mixture models do not require users to pre-specify subsets of sites, and instead calculate the likelihood of every site under every model, while co-estimating the model weights and parameters.

Abstract: Despite the increasing utilization of total ankle replacement (TAR) for end-stage ankle arthritis, there remains a paucity of long-term follow-up data comparing arthroplasty to arthrodesis. The aim of the current paper was to provide the long-term clinical outcomes of TAR and ankle arthrodesis (AA), measured with use of validated scoring instruments, in a prospective multicenter cohort of patients with ankle arthritis. This cohort from the Canadian Orthopaedic Foot and Ankle Society (COFAS) Prospective Ankle Reconstruction Database comprised patients who underwent TAR or AA between 2001 and 2007.

Little is known about the epidemiology of leptospirosis in the Dominican Republic, the second most populous country in the Caribbean. We report on findings from a multi-stage household survey across two regions in the country that reveals a previously under-estimated burden of human Leptospira infection. Our findings, based on the reference-standard microscopic agglutination test, indicate a complex picture of serogroup diversity, spatial heterogeneity in infection and risk, and a marked discrepancy between reported cases and serologically estimated infections.

The brain's complex distributed dynamics are typically quantified using a limited set of manually selected statistical properties, leaving the possibility that alternative dynamical properties may outperform those reported for a given application. Here, we address this limitation by systematically comparing diverse, interpretable features of both intra-regional activity and inter-regional functional coupling from resting-state functional magnetic resonance imaging (rs-fMRI) data, demonstrating our method using case-control comparisons of four neuropsychiatric disorders. Our findings generally support the use of linear time-series analysis techniques for rs-fMRI case-control analyses, while also identifying new ways to quantify informative dynamical fMRI structures.

There is increasing awareness that marine invertebrates such as abalones are at risk from the combined stressors of fishing and climate change. Abalones are an important marine fishery resource and of cultural importance to Indigenous and non-Indigenous people. A highly priced marine delicacy, they are inherently vulnerable: individuals are slow-growing and long-lived and successful reproduction requires dense assemblages.

Athletes in collision sports frequently sustain repetitive head impacts (RHI), which, while not individually severe enough for a clinical mild traumatic brain injury (mTBI) diagnosis, can compromise neuronal organization by transferring mechanical energy to the brain. Although numerous studies target athletes with mTBI, there is a lack of longitudinal research on young collision sport participants, highlighting an unaddressed concern regarding cumulative RHI effects on brain microstructures. Therefore, this study aimed to investigate the microstructural changes in the brains' of high school rugby players due to repeated head impacts and to establish a correlation between clinical symptoms, cumulative effects of RHI exposure, and changes in the brain's microstructure.

Highly Efficient Transpeptidase-Catalyzed Isopeptide Ligation.

J Am Chem Soc

December 2024

Institute for Molecular Bioscience, Australian Research Council Centre of Excellence for Innovations in Peptide and Protein Science, The University of Queensland, Brisbane, Queensland 4072, Australia.

Transpeptidases are specialized enzymes that have evolved for site-selective modification of peptides and proteins at their backbone termini. Approaches for adapting transpeptidases to catalyze side chain modifications are substantially more restricted, and typically rely on large recognition tags or require specific reaction conditions that are not easily compatible with broader applications. Here we show that the engineered asparaginyl ligase AEP1 catalyzes direct isopeptide ligation by accepting an internal 2,3-diaminopropionic acid (Dap) residue adjacent to Leu, a motif that mimics the canonical N-terminal Gly-Leu substrate.
