Explaining distance deterrence variation in urban mobility with spatiotemporal features
Distance deterrence, often quantified through the gravity model, has been used to characterize urban mobility, yet which urban and contextual features are linked with its within-city variation remains unclear. Using large-scale origin–destination mobility data comprising about 4....

Polycythemia vera with unusual complications in a cat
Abstract Background Polycythemia vera (PV) is an uncommon hematologic disorder in cats that typically manifests as erythrocytosis. Cases with concurrent increases in other cell lines such as leukocytes are rarely reported, and vascular complications other than neurologic abnormal...

Autoimmune Gastritis: An Evolving Entity
Autoimmune gastritis (AIG) has long occupied an awkward place in clinical practice.For most of the 21th century, it was viewed mainly through its hematologic endpoint-pernicious anemia-and seen as a rare, late diagnosis of limited relevance to the endoscopist.That perception has...

Pair correlation conjecture for the zeros of the Riemann zeta‐function I: Simple and critical zeros
Abstract Montgomery in 1973 introduced the pair correlation conjecture (PCC) for zeros of the Riemann zeta‐function. He also conjectured that asymptotically 100% of the zeros are simple. His reasoning to support these two conjectures used the Riemann hypothesis (RH). Building on...

Age- and sex-adjusted genomic differences between Korean and Beat AML cohorts
Genomic profiling plays a central role in risk stratification and therapeutic decision-making in acute myeloid leukemia (AML), yet the clinical implications of population-specific genomic architectures remain incompletely defined. We conducted a prospective, multicenter study of...

Environmental Analysis and Prospect of Rare Earth Recovery Technology from Electronic Waste
Rare earth elements (REEs) are essential resources for high-tech industries including semiconductors, batteries, electric vehicles, and wind power generation; however, the current global supply chain is overwhelmingly concentrated in specific countries. As environmental pollution...
