Studying the spatiotemporal distribution pattern of carbon storage, balancing land development and utilization with ecological protection, promoting urban low-carbon sustainable are important topics under China’s “dual strategy” (Carbon emissions stabilize harmonize natural absorption). However, existing research has paid little attention to impact use changes different spatial policies on provincial-scale ecosystem storage. In this study, we established a density database for Liaoning...

The quantitative assessment of ecosystem health is important for interpreting the ecological effects land use changes and formulating effective measures sustainable development by policymakers. This study investigated response to landscape patterns in karst mountainous regions southwest China taking Guiyang City as a case area assessing spatial temporal from 2008 2017 using vigor–organization–resilience model; it analyzed influence on overlay analysis, Dunnett’s T3 test, Spearman correlation...

Keystone taxa are drivers of microbiome structure and functioning, which may play critical roles in microbiome-level responses to recalcitrant pollution a key bioremediation. However, the characterization manipulation such is major challenge due complexity microbial communities rapid turnover both time space. Here, microcosms were set up with benzo[a]-pyrene (BaP) and/or nitrate based on C-rich, S-rich, N-limited mangrove sediments as reductive experimental models trigger track keystone...

We have developed a new type of ultrasound (US) contrast agent, consisting gas core, layer superparamagnetic iron oxide Fe3O4 nanoparticles (SPIO) and an oil in water outermost layer. The newly US agent microbubbles mean diameter 760 nm with polydisperity index (PI) 0.699. Our vitro vivo experiments shown that they the following advantages compared to gas-encapsulated microbbubbles without SPIO inclusion: (1) provide better for images; (2) SPIO-inclusion generate higher backscattering...

The conflicts between nature reserves and surrounding communities are attracting growing attention. These conflicts, through complexities of resource, socio-economic, governance conditions, produced interactive processes. We report a case study Taibai Mountain National Nature Reserve in Shaanxi, China, where we employ Ostrom's Social Ecological System framework conflict theory, context high motivation investment rural China. results reveal that social ecological systems each the three...

Plant-based biochar was demonstrated promising capability in adsorbing microplastic particles (MPs) within soil porous mediums. However, biochar's function mitigating MPs' vertical penetration during wetting-drying cycles, typical of seasonal precipitation and evaporation, remains uncertain. Furthermore, few studies have investigated the structures how combines with soil. This study conducted column tests to assess MPs retention capabilities soil-biochar media under saturated conditions. The...

With urbanization accelerating, the demand for rapid commuting has spurred development in suburban railway systems and heightened focus on ride comfort, particularly regarding interior noise. This study used Statistical Energy Analysis to create validate a noise prediction model trains. The model, tested against real data, showed high accuracy. Findings revealed overall levels of 68-76 dB, with mid-carriages slightly noisier than end cabins. Noise mainly comes from bottom bogie area, while...

Shanxi Province is the northernmost distribution range of Chinese forest musk deer (Moschus berezovskii), with wild populations scattered across Zhongtiao (ZT), Lüliang (LL), and Taiyue (TY) mountain ranges. Using line transect surveys local guide assistance, coupled infrared camera data, this study systematically collected fecal samples from five nature reserves three Genetic diversity was analyzed using mtDNA control region, which yielded 129 effective sequences 656 bp 20 distinct...

A force-finding analysis is crucial for a single-layer cable net glass curtain structure. In engineering applications, the boundary such structure exhibits limited rigidity, which frequently causes prestress loss and differential changes in reaction force of supports at both ends during construction process. Here, we propose nonlinear method based on inherent symmetry structural stiffness these large-scale wall structures. Our utilizes undirected subgraphs to preprocess analyze The their...

Microbial electrosynthesis (MES) offers a sustainable and low-carbon approach for CO2 valorization, with Shewanella oneidensis (S. oneidensis) MR-1 identified as an ideal microbe MES. However, no prior research has demonstrated that S. can directly metabolize into multicarbon (C2+) products due to its inability perform the intracellular formate assimilation pathway. Here, we provide initial proof-of-concept evidence of direct bioelectrochemical reduction C4 product malate. Specifically,...

Designing and optimizing target structures is one of the most critical steps in high‐intensity laser experiments, like laser‐driven neutron sources, which are increasingly recognized for their compactness portability. Herein, an artificial intelligence (AI)‐assisted design approach that leverages AI algorithms combination with particle‐in‐cell simulations proposed. This newly AI‐optimized structure addresses limitations conventional approaches, such as foam targets or wire‐array structures....

ABSTRACT Urban remnant habitats, which are crucial biodiversity hotspots, facing severe threats from urban expansion and infrastructure development. However, the impact of park utilization on plant diversity in these habitats remains underexplored. This study focused eight mountain parks (URMP) Guiyang City, China, a karst region, comprehensive evaluation system for disturbances was established using 11 indicators across four dimensions. We analyzed responses to different disturbance types...

Abstract Colonies are the basic geometric building blocks of coral reefs. However, forming regulations both colonies and reefs still not understood adequately. Therefore, in this study, we reconstructed 25 samples using high‐resolution micro‐computed tomography to investigate growth patterns parameters. Our skeleton canal reconstructions revealed characteristics different species, further visualized axes rings understand directions. We drew a grayscale map calculated void ratios ascertain...
