Summary: The study found that extreme PM2.5 events in Mesa Verde were influenced by different sources, with spring and summer events mainly driven by dust and smoke, and winter events influenced by other sources. Over the past decade, there has been an increase in the proportion of dust and smoke events compared to other events.

Summary: Many Mesa Verde cliff dwellings were occupied before depopulation, providing unique research opportunities. Bioarchaeological data from Wetherill Mesa burials were collected and analyzed, revealing increased physiological stress and worsening health among Pueblo III cliff dwellers. The findings suggest that resource availability, living conditions, and violence might have motivated migration.

Summary: In 1954, archaeologists and dendrochronologists claimed to have found evidence of ancient stone-axe-cut tree limbs in a small grove of Douglas-fir trees in Mesa Verde National Park. However, subsequent research could not confirm this assertion.

Summary: Gold carbenes are highly active in homogeneous gold catalysis, facilitating various transformations including C-H/X-H insertions, cyclopropanations, and 1,2-migrations. While 1,2-migrations onto gold carbene centers have received less attention compared to other reactions, they have the potential to be a powerful tool for constructing molecular complexity rapidly and simply.

Summary: Two magnetic braking models are implemented in MESA for use in the MIST stellar model grids, but the detailed physics behind magnetic braking are uncertain. While each model tested can reproduce aspects of the data, neither fully accounts for the observations, suggesting the need for further improvement. The study also indicates a missing mass dependency in these braking models to better match the rotation periods observed in clusters older than 1 Gyr.

Summary: Pinon-juniper woodlands in the southwestern United States are facing threats from changing climate and more frequent fires. A study in Mesa Verde National Park found that two types of woodlands, sprouting woodlands and obligate seeding woodlands, showed different levels of resilience and vulnerability to invasion by nonnative plant species after recent fires.

Summary: MESA is a prospective study aimed at studying subclinical cardiovascular disease, providing new tools for public health policy, population screening, and clinical decision-making. The concepts developed in MESA have informed international patient care guidelines, making it a beacon for collaborative science.

Summary: The Atlantic hurricane activity is influenced by multiple climate modes at seasonal-to-interannual scales. Among them, the Atlantic Nino/Nina is the dominant mode of sea surface temperature variability during the hurricane season. The Atlantic Nino enhances African easterly wave activity and increases the likelihood of powerful hurricanes developing near the Cape Verde islands.

Summary: Supermassive stars formed at z similar to 15-20 are strong contenders for the origin of the first quasars, with over 200 of them discovered at z > 6. These stars are likely to form in pristine, atomically cooled haloes interacting with strong Lyman-Werner ultraviolet backgrounds or high supersonic baryon streaming flows. This study explores the evolution of supermassive stars with a larger and finer grid of accretion rates, revealing their final masses and divergent evolutionary paths at different accretion rates.

Summary: This research focuses on mathematical modeling in complex biological systems with multiple types of individuals coexisting in different populations, with migratory phenomena allowed. A class of mathematical models is proposed to describe the demographic dynamics of these systems, using a probability model defined by a sequence of random matrices. The study shows that the stochastic sequence can be analyzed within the framework of multitype branching process theory, with probabilistic properties and limiting results established. An illustrative example on the population dynamics of biological systems formed by long-lived raptor colonies is presented as an application.

Summary: Transition-metal-catalyzed tandem reactions have become important in organic chemistry due to their high efficiency. Metal-migration-based tandem reactions allow the incorporation of functional groups into specific positions and the construction of complex structures, providing a complementary approach to traditional methods. This review summarizes the progress of 1,4-Pd migration reaction in the past two decades and categorizes the migration process, highlighting different migration mechanisms and strategies for improving selectivity.

Summary: Derived from structurally similar precursors, two different azidodiboranes underwent distinct aryl migration reactions triggered by different boron-boron separation distances. A shorter boron-boron distance led to heterolateral aryl migration and the formation of a seven-membered azadiborepin, while a longer boron-boron distance resulted in a stable bis-azidoborane scaffold. The pyrolysis of the bis-azidoborane led to the formation of an eight-membered oxazadiborocine through homolateral aryl migration and subsequent [3+2] cycloaddition. Density functional theory (DFT) calculations revealed that the boron-boron separation distances were the intrinsic factors driving the distinct migrations.

Summary: Edge computing capabilities in 5G wireless networks can reduce latency for mobile users by offloading computing tasks from user devices to nearby edge servers. This paper introduces MoDEMS, a system model and architecture that addresses the challenges of handling long-term user mobility in offloading, aiming to minimize service provider cost and user latency. The authors propose alternative heuristic algorithms for solving the cost minimization problem and validate the results through various experiments, showing a 33% reduction in latency compared to previous migration approaches.

Summary: Several migrations have turned the Carpathian Basin into a melting pot in Europe. Recent studies using ancient genomes provide evidence that European Huns, Avars, and Magyars have Asian origins, and also reveal significant within-group variability associated with social structure.
