Article Synopsis
- Stochastic analytic continuation (SAC) enhances the ability to relate quantum Monte Carlo data to measurable dynamic response functions by resolving spectral features like narrow peaks effectively.
- Recent advancements in SAC have improved the accuracy of identifying sharp spectral features, but the challenge remains due to the complexity and ambiguity of the analytic continuation problem, where multiple outcomes may seem valid.
- This study introduces a machine learning-based cross-validation technique to objectively select the most probable spectral representation from different parametrizations, showcasing its applicability to both quantum Monte Carlo and broader analytic continuation contexts.
Article Synopsis
- * Our findings show that the EE has critical corner contributions that scale logarithmically with system size, aligning well with predictions from a large-N conformal field theory that has SO(5) symmetry.
- * We emphasize the importance of how we partition the lattice, as improper choices can lead to misleading logarithmic contributions; using a 45° tilted cut reveals crucial microscopic aspects of EE that conformal field theory does not fully capture.
Background: The incidence of inflammatory bowel disease (IBD) is increasing. The prevalence of overweight and obesity is increasing in parallel with IBD and could contribute to IBD development. The aim of this study was to assess the relationship between weight change and the risk for IBD.

Background: There is growing evidence of the role of the mycobiome in inflammatory bowel disease (IBD). Variations within phenotypes and activity and with prognosis have been poorly studied.
Methods: A total of 111 individuals were prospectively enrolled: 89 IBD patients (52 ulcerative colitis and 37 Crohn's disease [CD]) and 22 healthy individuals.
Background: Previous studies have shown that the rapid transition to emergency remote teaching due to the COVID-19 pandemic was challenging for healthcare teachers in many ways. This sudden change made them face ethical dilemmas that challenged their values and ethical competence.
Research Aim: This study aimed to explore and gain a deeper understanding of the ethical dilemmas healthcare teachers faced during the COVID-19 pandemic.
