Summary: This research compares the water footprint of vernacular structures (such as adobe, brick, stone, and wood) with modern structures (steel and concrete) in residential buildings. The study finds that the grey water footprint of vernacular buildings is significantly smaller than that of modern buildings, while the blue water footprint is mainly related to construction personnel. The study evaluates the water footprint of both vernacular and contemporary building practices, considering their potential for sustainable building practices.

Summary: The continuous rise in global beverage consumption leads to significant energy consumption and carbon emissions across the entire life cycle of beverage products. A new product carbon footprint model is developed to evaluate the carbon emissions of carbonated drinks at different stages, with a focus on retail and distribution stages. Optimization models for retail distribution routing and analysis of vending equipment are explored to reduce energy consumption and carbon footprint. Future studies could focus on comparing beverage products from different countries and implementing measures like dynamic routing distribution for sustainable development.

Summary: Sustainable production planning involves reducing carbon emissions and energy consumption. A fuzzy multi-objective model is proposed to minimize carbon emissions and energy consumption, offering a better compromise solution for production planning. Linear and non-linear membership functions are used to characterize fuzziness, and two approaches are proposed for dealing with empirical data points in nonlinear cases.

Summary: This paper analyzes the influence of the Froude number on the flow field interference and trajectory characteristics of successively launched underwater multiple projectiles. The results show that the trajectory of the projectiles is significantly influenced by the Froude number, with greater interference occurring under a downwind launch sequence and less interference during an upwind launch sequence. Therefore, it is recommended to use the upwind launch sequence to increase the success rate of the successively launched underwater projectiles.

Summary: We have designed and demonstrated a reconfigurable channel add-drop filter based on an antisymmetric multimode photonic crystal nanobeam cavity in a silicon waveguide. The proposed device can selectively filter and reflect specific modes in the waveguide to achieve channel add-drop filtering. The device has shown high performance with a high extinction ratio and low insertion loss. Reconfigurable add-drop functionality is achieved by heating the nanobeam cavity to tune the filtering wavelength.

Summary: Resonance fluorescence is a promising method for generating indistinguishable single photons and manipulating quantum states in quantum information processing. However, integrating quantum systems on one chip faces challenges such as randomness and scattering background. This study presents an organic-inorganic hybrid integrated quantum photonic platform that enables background-free resonance fluorescence of single molecules with ultrastable lifetime. The platform allows collective alignment of many isolated molecules with the photonic waveguide, enabling on-chip generation and routing of high-quality single photons.

Summary: In this study, we present a detailed evaluation of the seismic connectivity between the Kunlun Pass-Jiangcuo fault and other active faults in the Bayan Har Block (BHB) in northeastern Tibet over the past 300 years. We found that the 2021 Mw 7.3 Maduo earthquake was delayed for more than 150 years due to the stress shadow resulting from fault interaction in the BHB. Moreover, the Maduo earthquake inhibited future seismic activity in certain segments of the surrounding strike-slip faults. This suggests that earthquakes on a fault might suppress earthquakes on neighboring faults in parallel strike-slip fault systems by creating a shadow zone in northeastern Tibet. This finding is significant for understanding earthquake generation and migration in northeastern Tibet and for comprehending fault interactions in similar fault systems globally.

Summary: Historically, the idea that ecosystems have geographical boundaries has been considered naive and impractical. However, advancements in remote sensing have allowed us to reliably detect spatial patterns and provide early warnings of potential critical transitions. This invites a reexamination of the role geographical boundaries play in explaining the concept of resilience, leading to a better understanding of the causal dynamics that lead to emergent self-organization.
