This study evaluates the mechanical performance and life cycle sustainability of post-consumer recycled polylactic acid (rPLA) for use in the fused filament fabrication of 3D-printed gear components. Five material compositions ranging from 0 % to 100 % rPLA blended with virgin PLA (vPLA) were assessed through tensile testing and gear function trials. To balance the technical evaluation, a comprehensive life-cycle sustainability assessment was conducted, incorporating environmental (ELCA), economic (LCC), and social (SLCA) indicators using a triple bottom line sustainability framework. Mechanical testing showed a slight reduction in tensile strength with increased rPLA content, with the 50:50 blend (V50:R50) achieving 52.83 MPa compared to 61.12 MPa for 100 % vPLA. All the blends maintained functional gear performance with no slippage. Environmentally, rPLA-rich blends significantly lowered global warming potential, cumulative energy demand, and abiotic resource depletion. Economically, although rPLA reduces raw material and energy costs, filament quality variability introduces preprocessing challenges, slightly increasing the overall production costs. Socially, rPLA-inclusive systems have demonstrated strong potential for improving local employment, training, and worker safety, particularly within decentralised recycling networks. The V50:R50 blend achieved the highest overall sustainability score (−1.35), offering the most balanced trade-off between mechanical performance and triple bottom line sustainability, outperforming both pure vPLA (−1.96) and pure rPLA (−1.75). These findings support the viability of rPLA in noncritical gear applications and underscore the importance of future research on quality assurance systems and cost-effective preprocessing technologies.

Differences in growth rates among broiler chickens within a single commercial genetic line have important economic implications; however, their molecular basis remains incompletely understood. This study analyzed male Ross 308 broilers classified into early- and late-growth lines based on weight gain from 1 to 5 days of age. We integrated RNA sequencing, metabolomics based on gas chromatography–mass spectrometry, and exploratory SNP analysis of pectoralis major muscle tissue collected at 35 days of age. Our integrative analysis revealed contrasting energy utilization programs. Slow early-growth phenotype chickens showed a Warburg-like metabolic profile characterized by glycolytic reliance, lactate fermentation, ketone metabolism, and enhanced proteolysis, accompanied by a bottleneck in mitochondrial oxidative phosphorylation. In contrast, fast early-growth phenotype chickens displayed enhanced oxidative phosphorylation, elevated glycerol-3-phosphate levels, and coordinated activation of pathways related to mitochondrial function and immune responses. Notably, reduced CARNS1 expression in the fast early-growth group suggested a potential trade-off with muscle quality, consistent with the role of carnosine in pH buffering and maintaining redox balance. Multi-omics integrated analysis revealed coordinated changes in metabolites and gene expression within glycolysis, lipid metabolism, and mitochondrial pathways. These findings indicate that the weight gain phenotype during early growth is associated with specific transcriptional and metabolic states during later development.

Understanding the synergies and trade-offs of cultivated land in quantity, quality, and ecology under the Land Requisition-Compensation Balance (LR-CB) policy is crucial for territorial spatial governance. Focusing on Neijiang, a representative hilly agricultural area in the southern Sichuan Basin, this study develops a multidimensional assessment framework integrating data from 1,718 village-level units, including land use surveys (2019–2023), remote sensing imagery. Methods such as dynamic change rate, landscape pattern indices, and ecosystem service value (ESV) evaluation are employed to analyze the spatial synergy and differentiation of cultivated land under the LR-CB policy. Results show that: (1) Quantity dimension: Cultivated land shows a clear spatial pattern of ‘large-scale occupation and small-scale compensation.’ Large patches of occupied cultivated land are concentrated in western Neijiang, whereas compensated patches are mainly clustered in the central and southwestern areas, forming a ‘high-density, small-area’ configuration. In total, 63.62% of administrative villages experience net losses of cultivated land. (2) Quality dimension: A distinct spatial mismatch between occupation and compensation is observed. Cultivated land is shifting toward lower elevations and gentler slopes, and 58.85% of villages have a contiguity occupation-compensation ratio below 1, suggesting that contiguous compensation has partially alleviated fragmentation. (3) Ecological dimension: The ESV of cultivated land in Neijiang shows an overall upward trend, with a cumulative increase of about 347 million yuan. A total of 88.42% of villages exhibit ESV enhancement, 71.20% of which is attributable to dryland, indicating strengthened ecological functions. However, most compensated land falls within ESV classes with only modest gains and has a weaker ecological foundation than the occupied land, implying that ecological equivalence under the LR-CB policy has yet to be achieved. This study offers a new perspective on how the LR-CB policy shapes cultivated land systems at the village scale, supporting the sustainable optimization of cultivated land resources in hilly regions.

Balconies are widely recognized for enhancing urban livability, making them attractive elements to incorporate in building renovation projects. However, their impact on energy performance remains insufficiently studied, particularly in temperate climates, like the Mediterranean, where both heating and cooling demands must be considered. This article evaluates the energy impacts of integrating open balconies into housing retrofits on the space conditioning demand of dwellings through spatialized analysis at the urban block scale. Focusing on Barcelona’s Eixample district, a parametric Urban Building Energy Modeling (UBEM) was employed to assess how balcony design interacts with urban morphology (orientation, obstructions), building features (window-to-wall ratio, WWR), and balcony length. Results reveal a seasonal trade-off at the block scale: balconies increase heating demand (0.1–1.6 kWh/m²·yr) by reducing winter solar gain but decrease cooling demand (0.1–3.8 kWh/m²·yr) through summer shading. Net effects vary by unit position, with south-facing and moderately glazed dwellings benefiting the most. Deeper balconies (1.5–2 m) amplify both effects, while optimal depth depends on the window-to-wall ratio. Under future climates, retrofits combining insulation and balconies mitigate rising cooling demands more effectively than insulation alone, reducing block-level demand by up to 16%. Although balconies alone show modest energy savings at the block scale, they enhance localized thermal resilience. The study highlights the need for integrated retrofit strategies that balance thermal insulation with solar protection to address both current and future energy challenges while enhancing occupant well-being.

Blockchain-based data storage methods offer strong data integrity, decentralized security, and transparent access control but also face scalability challenges, high computational costs, and complex data management. This study provides a comprehensive review of on-chain, off-chain, and hybrid storage architectures, analyzing their security vulnerabilities, performance trade-offs, and industry-specific applications. On-chain data storage ensures immutability, data integrity, and high security by storing data directly on the blockchain; however, it is associated with high transaction costs and scalability limitations. In contrast, off-chain solutions reduce costs and enhance performance by storing data outside the blockchain but introduce risks related to data integrity and access security in decentralized environments. Hybrid approaches aim to balance security, cost, and scalability by integrating the strengths of both on-chain and off-chain solutions. This study examines the fundamental components of blockchain-based data storage systems, their sector-specific applications, and the technical challenges they present. Additionally, it explores the trade-offs between security, cost, and decentralization, offering insights into blockchain storage optimization strategies. As a result, this study evaluates the optimization of security protocols, the efficiency of hybrid systems, and the sustainability of distributed storage solutions, contributing to future research in this field.

The analysis of travel behavior constitutes a fundamental component in urban transportation studies. This study examines Bandung, Indonesia, and Kuantan, Malaysia, as representative medium-sized cities with distinct road network typologies: radial-concentric in Bandung and corridor-based in Kuantan. A systematic literature review was employed to identify ten parameters of travel behavior, which were further evaluated using descriptive comparison, SWOT analysis, and radar chart visualization. The findings indicate that Bandung’s transport system is primarily dominated by paratransit and ride-sourcing services, which provide substantial flexibility and local accessibility. However, the system is constrained by weaknesses in reliability, comfort, safety, and integration with formal modes. In contrast, Kuantan demonstrates relative strengths through its formalized bus system (Rapid Kuantan), which ensures standardized fares, higher comfort levels, and improved safety, although challenges remain in terms of flexibility, last-mile connectivity, and schedule adherence. SWOT analysis underscores complementary opportunities, with Bandung requiring formalization and digital integration of paratransit, while Kuantan could enhance adaptability through feeder and microtransit services. The radar chart highlights a trade-off between flexibility and service quality, confirming that medium-sized cities must balance these dimensions. Overall, the study develops a transferable ten- parameter framework for comparative assessment of travel behavior, contributing to transport planning strategies in rapidly urbanizing contexts.

Objective The world is still in a phase of rapid industrialization and urbanization. Excessive carbon emissions has become the primary root cause of various urban or even global environmental problems, further impacting human physiological and psychological health. Cities are the largest sources of carbon emissions and are crucial regions for achieving carbon neutrality goals. Urban blue-green infrastructure (UBGI), comprising natural, semi-natural, or artificial green and blue spaces within cities, is considered as the most important carbon sink space in urban areas and has increasingly attracted widespread attention from researchers. However, there are still many unresolved issues regarding the effectiveness of UBGI in carbon sink enhancement and emission reduction: 1) How is the energy efficiency of carbon sink enhancement and emission reduction measured, and what factors influence it? 2) What are the mechanisms and pathways through which UBGI enhances carbon sink and reduces carbon emission? 3) How can UBGI be regulated to better enhance its effectiveness in carbon sink enhancement and emission reduction? 4) What are the limitations and potential directions for future research? This research aims to address these issues and propose scientifically sound planning strategies for UBGI construction to achieve urban carbon neutrality goals.Methods Through literature synthesis and deduction, this research organizes and analyzes the multi-scale measurement methods for UBGI’s efficiency in carbon sink enhancement and emission reduction, identifies corresponding influencing factors at each scale, and constructs multi-scale planning strategies for UBGI based on the logical framework of “measurement methods–influencing factors – planning strategies”.ResultsThe research proposes UBGI planning strategies across three spatial scales (site, community and urban area), covering three key aspects: Carbon sequestration and sink enhancement, carbon reduction based on temperature reduction (or preservation), and travel-related carbon reduction. Based on current research gaps and planning needs, five major research topics are further identified. This research provides a detailed analysis of the measurement methods and influencing factors of UBGI’s efficiency in carbon sink enhancement and emission reduction from three perspectives: Carbon sequestration and sink enhancement, carbon reduction based on temperature reduction (or preservation), and travel-related carbon reduction. The research finds significant differences in the measurement methods for UBGI’s efficiency in carbon sink enhancement and emission reduction efficiency across different scales. Contradictory results may occur at different scales, and large-scale research often lacks characterization of internal features, leading to unclear mechanisms of influencing factors and obstructing practical planning. Based on the interpretation of UBGI’s mechanisms for carbon sink enhancement and emission reduction at different scales, this research formulates UBGI planning strategies across three spatial scales (site, community, and urban area). These strategies include: 1) At the site scale, for carbon sequestration and sink enhancement – carbon sink at the source, land balance, and ecological design; for emission reduction – symbiosis with buildings and integration into daily life. 2) At the community scale, for carbon sequestration – overall balance of revenue and expenditure, precise positioning, and proper interconnection of the carbon chain; for emission reduction – incorporation of cool islands and co-construction. 3) At the urban area scale, for carbon sequestration – enhancement of ecological space management and establishment of a carbon-safe pattern; for emission reduction – demand-based layout and organic dispersion. Finally, the research proposes five major research topics for the planning of UBGI’s carbon sink enhancement and emission reduction: How to construct unified measurement methods for UBGI’s efficiency in carbon sink enhancement and emission reduction across scales? How to measure UBGI’s efficiency in carbon reduction based on temperature reduction (or preservation) at the site scale? How to integrate the pathways of carbon sink enhancement and emission reduction for a life cycle assessment of UBGI? How to balance UBGI’s carbon sink enhancement and emission reduction with other functions to achieve the optimal layout for comprehensive benefits? How to achieve urban “carbon justice” through UBGI? Conclusion The carbon sink pathway of the strategy framework requires “carbon sink at the source – precise positioning – safe pattern”, and the emission reduction pathway requires “symbiotic integration – co-construction and sharing – organic dispersion”. The key trade-offs between these two pathways at three spatial scales may provide theoretical support and practical guidance for UBGI construction and management. The five major research topics mentioned above may offer valuable assistance for UBGI construction and future research.

Effective natural resource management is essential for promoting economic stability, environmental sustainability, and long-term global resilience. As the world’s two largest economies, China and the United States play a pivotal role in shaping global resource extraction policies, making it critical to understand the economic and regulatory factors driving their strategies. This study investigates the effects of trade openness, environmental tax, financial depth, and renewable energy consumption on natural resource extraction in both countries. After confirming data stationarity using unit root tests, the analysis employs the bounds testing approach and the Nonlinear Autoregressive Distributed Lag (NARDL) model to ensure robust empirical estimation. The results reveal that financial depth and trade openness are significant drivers of natural resource extraction in both economies, with stronger long-term effects evident in China. Environmental taxes emerge as an effective regulatory mechanism, particularly in the United States, while renewable energy consumption shows a negative but statistically insignificant impact on resource extraction in both contexts. In the short run, trade openness and financial depth consistently promote resource extraction, whereas the effects of environmental taxes and renewable energy consumption vary over different time horizons. These findings highlight the need for integrated, country-specific policy frameworks that balance economic growth with sustainable resource management. The study offers valuable insights for policymakers seeking to align national strategies with global sustainability goals and to strengthen resource governance practices.

Abstract Cellular chromatin displays heterogeneous structure and dynamics, properties that control diverse nuclear processes. Models invoke phase separation of conformational ensembles of chromatin fibers as a mechanism regulating chromatin organization in vivo. Here we combine biochemistry and molecular dynamics simulations to examine, at single base-pair resolution, how nucleosome spacing controls chromatin phase separation. We show that as DNA linkers extend from 25 bp to 30 bp, as exemplars of 10 N + 5 and 10 N (integer N) bp lengths, chromatin condensates become less thermodynamically stable and nucleosome mobility increases. Simulations reveal that this is due to trade-offs between inter- and intramolecular nucleosome stacking, favored by rigid 10 N + 5 and 10 N bp linkers, respectively. A remodeler can induce or inhibit phase separation by moving nucleosomes, changing the balance between intra- and intermolecular stacking. The intrinsic phase separation capacity of chromatin enables fine tuning of compaction and dynamics, likely contributing to heterogeneous chromatin organization in vivo.

In the global agroecosystem, plant diseases, as important factors affecting crop yield, quality and ecological balance, have long been the focus of agricultural scientific research and practice. With climate change, the increase in international trade and the transformation of agricultural production methods, the frequency and distribution of plant diseases and the extent of their damage have shown a trend of increasing complexity and intensification. This not only poses a serious challenge to food security, but also poses a potential threat to sustainable agricultural development and biodiversity conservation. The aim of this paper is to provide an overview of current research advances and methods that can be applied to computer- based recognition of plant diseases and pests, as well as an outlook on future developments. The paper focuses on the recognition of plant diseases, categorizes the problem scenarios for recognition (single and multi-class) and in this way summarizes some informative methods (detection and tracking) and learning approaches for recognition.

Balancing scientific exposition and narrative engagement is a central challenge in science communication. To examine how to achieve balance, we conducted a formative study with four science communicators and a literature review of science communication practices, focusing on their workflows and strategies. These insights revealed how creators iteratively shift between exposition and engagement but often lack structured support. Building on this, we developed SpatialBalancing, a co-writing system that connects human spatial reasoning with the linguistic intelligence of large language models. The system visualizes revision trade-offs in a dual-axis space, where users select strategy-based labels to generate, compare, and refine versions during the revision process. This spatial externalization transforms revision into spatial navigation, enabling intentional iterations that balance scientific rigor with narrative appeal. In a within-subjects study (N=16), SpatialBalancing enhanced metacognitive reflection, flexibility, and creative exploration, demonstrating how coupling spatial reasoning with linguistic generation fosters monitoring in iterative science communication writing.

As an extended and more complete version of the primary QCD nucleation model presented in Ref. [1], the new model introduces explicitly the transition balance and formulates it in both macroscopic and microscopic descriptions. The microscopic description of the transition balance in QCD nucleation is implemented in a kinetic parton cascade model and tested for a first-order phase transition from gluons to pions in a one-dimensional expansion with Bjorken boost invariance.

Decentralized exchange platforms such as Uniswap and Balancer operate on several pools where each pool contains two or more cryptocurrencies and constitutes direct trading pairs. The drawbacks here are that liquidity providing requires contribution of tokens in a specific proportion, and trading may require hopping between pools, hence increasing transaction fee and gas fee. We propose an automated market maker (AMM) protocol where liquidity providers can deposit any amount of tokens into the pool. The protocol will preserve the proportion of tokens by total value at the time of deposit and can be seen as a personalized self-balancing portfolio manager. In addition, since the invariant function is dynamic, all exchange pairs are executed from a single composite pool. Nevertheless, the scheme is vulnerable to flash loan attacks and must be used in conjunction with preventive measures.

The objective of this study is to examine the relationship between macroeconomic variables and the financial liquidity of companies. In this context, two main research questions were formulated. Firstly, which macroeconomic variables impact the financial liquidity of companies? Secondly, what is the direction and strength of the influence of these macroeconomic variables on the financial liquidity of companies? This study employed panel data analysis conducted on an unbalanced panel of 5327 Polish enterprises over the period 2003–2021. The primary research method employed was linear regression (pooled OLS) with robust standard errors clustered at the firm level. The main results of this study indicate that (1) the majority of macroeconomic variables, which illustrate the overall efficiency of the economic system (GDP per capita, ratio of foreign trade goods balance to GDP, CPI, and money supply), demonstrate a positive relationship with corporate liquidity; only the consumption-to-GDP ratio exhibits a negative relationship; (2) a positive relationship was observed between the number of building permits for housing and financial liquidity; (3) variables from the informal institutional environment indicate a positive relationship for the employment rate and a negative relationship for the share of the pre-working age population in the overall population; (4) the relationship between the ratio of internal expenditures on research and development to GDP and corporate liquidity is positive. This study addresses limitations of previous research by examining the impact of macroeconomic factors, particularly those from the institutional and technical environment, on corporate financial liquidity.

Since the beginning of the 21st century, Africa has once again become a space of competition between the great powers in the context of a new geopolitical configuration of the world. Despite the formal independence of the continent’s countries in the 1960s, Africa is still de facto dependent on the major actors of world politics, which calls into question its subjectivity in international politics. The search for a change in relations with the countries of the continent is reflected, inter alia, through the organization of “African” summits by major world powers. The organization of Russia-Africa summits in 2019 and 2023 confirms the thesis that Africa is a strategically important platform in the search for a balance of power between the great powers. However, in all these diplomatic initiatives, Africa has the right and the opportunity to determine for itself the key issues that will help it to effectively embed itself in the new geopolitical system while strengtheni ng its economic, social, and political importance. Even if the socio-economic context remains dependent on numerous endogenous and exogenous factors, the new formula that Africa is facing today can now be achieved not necessarily through multilateral meetings alone. Africa’s role as a systemically important component of the international system has been limited by its relatively low level of participation in world trade and GDP. It therefore seems appropriate for the various Russia-Africa summits to move beyond the traditional framework in which the continent is underrepresented and redefine the boundaries of the partnership towards mutual dynamics, both politically and economically, which are the main thrusts of the Russia-Africa summits.

Large language models (LLMs) continue to exhibit noteworthy capabilities across a spectrum of areas, including emerging proficiencies across the health care continuum. Successful LLM implementation and adoption depend on digital readiness, modern infrastructure, a trained workforce, privacy, and an ethical regulatory landscape. These factors can vary significantly across health care ecosystems, dictating the choice of a particular LLM implementation pathway. This perspective discusses 3 LLM implementation pathways—training from scratch pathway (TSP), fine-tuned pathway (FTP), and out-of-the-box pathway (OBP)—as potential onboarding points for health systems while facilitating equitable adoption. The choice of a particular pathway is governed by needs as well as affordability. Therefore, the risks, benefits, and economics of these pathways across 4 major cloud service providers (Amazon, Microsoft, Google, and Oracle) are presented. While cost comparisons, such as on-demand and spot pricing across the cloud service providers for the 3 pathways, are presented for completeness, the usefulness of managed services and cloud enterprise tools is elucidated. Managed services can complement the traditional workforce and expertise, while enterprise tools, such as federated learning, can overcome sample size challenges when implementing LLMs using health care data. Of the 3 pathways, TSP is expected to be the most resource-intensive regarding infrastructure and workforce while providing maximum customization, enhanced transparency, and performance. Because TSP trains the LLM using enterprise health care data, it is expected to harness the digital signatures of the population served by the health care system with the potential to impact outcomes. The use of pretrained models in FTP is a limitation. It may impact its performance because the training data used in the pretrained model may have hidden bias and may not necessarily be health care–related. However, FTP provides a balance between customization, cost, and performance. While OBP can be rapidly deployed, it provides minimal customization and transparency without guaranteeing long-term availability. OBP may also present challenges in interfacing seamlessly with downstream applications in health care settings with variations in pricing and use over time. Lack of customization in OBP can significantly limit its ability to impact outcomes. Finally, potential applications of LLMs in health care, including conversational artificial intelligence, chatbots, summarization, and machine translation, are highlighted. While the 3 implementation pathways discussed in this perspective have the potential to facilitate equitable adoption and democratization of LLMs, transitions between them may be necessary as the needs of health systems evolve. Understanding the economics and trade-offs of these onboarding pathways can guide their strategic adoption and demonstrate value while impacting health care outcomes favorably.

This paper proposes a two blocks and three regions economic geography model that can account for the most salient stylized facts experienced by Eastern European transition economies during the period 1990 2005. In contrast to the existing literature, which has favored technological explanations, trade liberalization is the only driving force. The model correctly predicts that in the first half of the period, trade liberalization led to divergence in GDP per capita, both between the West and the East and within the East. Consistent with the data, in the second half of the period, this process was reversed and convergence became the dominant force.

Structural balance theory predicts that triads in networks gravitate towards stable configurations. The theory has been verified for undirected graphs. Since real-world networks are often directed, we introduce a novel method for considering both transitivity and sign consistency for evaluating partial balance in signed digraphs. We test our approach on graphs constructed by using different methods for identifying edge signs: natural language processing to infer signs from underlying text data, and self-reported survey data. Our results show that for various social contexts and edge sign detection methods, partial balance of these digraphs are moderately high, ranging from 61% to 96%. Our approach not only enhances the theoretical framework of structural balance but also provides practical insights into the stability of social networks, enabling a deeper understanding of interpersonal and group dynamics across different communication platforms.

Abstract Complex life histories are frequently associated with biological trade‐offs, as the use of one trait can decrease the performance of a second trait due to the need to balance competing demands to maximize fitness. Here, we examine growth patterns in invasive adult male northern crayfish (Faxonius virilis) that are indicative of a potential trade‐off between energy allocation for body size versus chelae size growth. Northern crayfish undergo cyclic dimorphism, a process characterized by seasonal morphological changes associated with reproductive status. We measured carapace length and chelae length before and after molting and compared these growth increments between the four morphological transitions of the northern crayfish. Consistent with our predictions, reproductive crayfish molting to the non‐reproductive form and non‐reproductive crayfish molting within the non‐reproductive form experienced a larger carapace length growth increment. Reproductive crayfish molting within the reproductive form and non‐reproductive crayfish molting to the reproductive form, on the other hand, experienced a larger growth increment in chelae length. The results of this study support that cyclic dimorphism evolved as a strategy for optimizing energy allocation for body and chelae size growth during discrete periods of reproduction in crayfish with complex life histories.

Gravitational waveforms play a crucial role in comparing observed signals to theoretical predictions. However, obtaining accurate analytical waveforms directly from general relativity remains challenging. Existing methods involve a complex blend of post-Newtonian theory, effective-one-body formalism, numerical relativity, and interpolation, introducing systematic errors. As gravitational wave astronomy advances with new detectors, these errors gain significance, particularly when testing general relativity in the non-linear regime. A recent development proposes a novel approach to address this issue. By deriving precise constraints - or balance laws - directly from full non-linear GR, this method offers a means to evaluate waveform quality, detect template weaknesses, and ensure internal consistency. Before delving into the intricacies of balance laws in full non-linear general relativity, we illustrate the concept using a detailed mechanical analogy. We'll examine a dissipative mechanical system as an example, demonstrating how mechanical balance laws can gauge the accuracy of approximate solutions in capturing the complete physical scenario. While mechanical balance laws are straightforward, deriving balance laws in electromagnetism and general relativity demands a rigorous foundation rooted in mathematically precise concepts of radiation. Following the analogy with electromagnetism, we derive balance laws in general relativity. As a proof of concept, we employ an analytical approximate waveform model, showcasing how these balance laws serve as a litmus test for the model's validity.
