Summary: The study investigates the microstructure evolution of uranium dioxide (UO2) due to xenon (Xe) accumulation through the growth of highly pressurized Xe bubbles using molecular dynamics simulations. Two stages characterized by bubble pressure are identified, with the evolution depending on the interatomic potentials and causing dislocations, phase transitions, and interfaces in UO2.

Summary: This study examines the issue of assessing damage due to explosions of cylindrical pressure vessels, specifically focusing on predicting the arrangement of cracks in the vessel wall before the explosion, known as the failure pattern. It finds that Bayesian statistics can be used to estimate the probabilities of these failure patterns, and that the Dirichlet-multinomial model can handle the uncertainty in these probabilities. The study suggests that probabilistic prediction of failure patterns based on past accident data is the most practical way to assess potential vessel fragmentation.

Summary: The evolution of two-phase flow, internal pressure, and thermodynamics responses during a BLEVE process with water were evaluated. It was found that increasing initial pressure initially leads to a higher rate of pressure rise, although this rate slightly decreases due to competitive effects between expansion flow and countercurrent flow. Countercurrent flow inhibits expansion flow, reducing boiling intensity, while pressure relief actions can intensify boiling explosions after crack formation.

Summary: This study characterized the pressure and temperature of LCO2-PB during a controlled BLEVE experiment, identifying that the cracking radius and distance can be controlled by adjusting parameters such as fill pressure, blasting pressure, and release orifice. Results showed that the action form of cracked coal can be controlled by adjusting initial parameters, reducing methane and greenhouse gas emissions.

Summary: This study investigates the pre-breakdown processes in water under ultra-long pulses and clarifies the intrinsic differences between bubbles and streamers, as well as the transition process from bubble to streamer. The research results indicate that the conductivity disparity between bubble and streamer leads to their diverse dynamic behaviors, with the development of bubble being driven by bottom-up growth and the development of streamer guided by top-down propagation. The final breakdown only occurs if the bubble expands to a critical size, triggering the bubble-streamer transition through a competitive process of growth and detachment.

Summary: In this study, we built a precisely characterized quantum simulator using cQED tools and successfully measured the finite frequency linear response of a non-trivial bosonic impurity problem. The experimental results quantitatively matched a perturbative calculation based on a microscopically calibrated model and revealed another many-body broadening phenomenon. Furthermore, we extended the usage range of the device and called for more advanced theoretical tools to model many-body quantum circuits. This work opens exciting perspectives for quantifying quantum entanglement near quantum critical points or accessing the dynamical properties of non-trivial many-body problems.

Summary: This study discusses the interaction between the nonlinear fluid motion induced by the collapse of a vapor microbubble and the elastic dynamics of the underlying solid. The collapse of the bubble creates an intense jet that pierces the bubble and impinges the solid, resulting in localized load and the excitation of elastic solid waves. It is speculated that the intense deformation of the solid induced by the liquid jet may lead to plastic deformation and surface damage.

Summary: Trapped atomic ion crystals serve as a leading platform in quantum simulations of spin systems, where programmable and long-range spin-spin interactions are achieved through excitations of phonons. In this study, we propose a complementary approach using phonons in trapped-ion crystals to simulate bosonic systems, mediated by excitations of trapped-ion spins. This scheme allows for high programmability across a dense graph of bosonic couplings, utilizing long-lived collective phonon modes in a trapped-ion chain. It is well-suited for tackling challenging problems such as boson sampling and simulations of long-range bosonic and spin-boson Hamiltonians.

Summary: This study develops a machine-learning-based multiscale simulation framework to investigate the mechanical controllability of topological defects in ferroelectric materials. The results reveal that the symmetry of mechanical loading plays a crucial role in determining the polar topological switching pathways. These findings provide insights into the rational control of ferroelectric topologies, which can be useful for the design of ferroelectric topotronics.

Summary: The cavitation characteristics during the spreading of a pure Sn liquid droplet subjected to ultrasonication were studied. Ultrasonic vibration realized the spreading of Sn droplet on the nonwetting pure Al substrate, but the oxide layer at the spreading front is difficult to remove. The high-speed photography result showed the presence of a noncavitation region consistently at the spreading front, and the width of the noncavitation region increased with the size of the spreading area. The bubble density decreased during spreading due to the decreased acoustic pressure.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Summary: Ocean depth affects microbial diversity, composition, and co-occurrence patterns of microplastic microbial communities. Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
