Article Synopsis
- Polarons, resulting from strong electron-phonon interactions, and spin-orbit coupling, which occurs in materials with heavy atoms, both significantly affect how charge and spin behave in certain materials, especially in transition metal oxides.
- The study introduces a new compound, BaNaCaOsO, where these two effects, usually considered separate, are found to interact and create "spin-orbital bipolarons."
- As more electrons are added to BaNaCaOsO, it maintains its insulating properties with a stable Mott gap, preventing it from transitioning to a metallic state, even at high levels of electron doping.
Article Synopsis
- - The study aimed to evaluate algorithms for detecting features of Systemic Lupus Erythematosus (SLE) using electronic health record data from the Chicago Area Patient-Centered Outcomes Research Network (CAPriCORN).
- - It found that patients with more SLE-related clinical encounters had significantly more positively identified SLE criteria domains, especially when data from multiple healthcare sites were analyzed.
- - The results indicate that these algorithms are effective in identifying SLE characteristics and highlight the advantages of using aggregated data from various institutions for enhanced detection.
Article Synopsis
- Researchers have discovered a new type of quantum coherence involving muons and quadrupolar nuclei, highlighting its potential as a quantum sensor for local charge environments.
- This phenomenon was observed in vanadium intermetallic compounds, which are important for superconductivity.
- The study shows that muons can effectively sense structural and charge-related properties in materials, even in scenarios where magnetic interactions are not present.*
Objective: Our objective was to develop algorithms to identify lupus clinical classification criteria attributes using structured data found in the electronic health record (EHR) and determine whether they could be used to describe a cohort of people with lupus and discriminate them from a defined healthy control cohort.
Methods: We created gold standard lupus and healthy patient cohorts that were fully adjudicated for the American College of Rheumatology (ACR), Systemic Lupus International Collaborating Clinics (SLICC) and European League Against Rheumatism/ACR (EULAR/ACR) classification criteria and had matched EHR data. We implemented rule-based algorithms using structured data within the EHR system for each attribute of the three classification criteria.
Doping Evolution of the Local Electronic and Structural Properties of the Double Perovskite BaNa Ca OsO.

We present a combined experimental and computational study of the effect of charge doping in the osmium based double perovskite BaNa Ca OsO for 0 ≤ ≤ 1 in order to provide a structural and electronic basis for understanding this complex Dirac-Mott insulator material. Specifically, we investigate the effects of the substitution of monovalent Na with divalent Ca, a form of charge doping or alloying that nominally tunes the system from Os with a 5d configuration to Os with 5d configuration. After an X-ray diffraction characterization, the local atomic and electronic structure has been experimentally probed by X-ray absorption fine structure at all the cation absorption edges at room temperature; the simulations have been performed using ab initio density functional methods.
