The influence of two canopy orientations (Upright and Tilted) in combination with two arm (branch) architectures (Shortened or Overlapped) on tree growth, yield components, fruit quality, and leaf mineral nutrients in an “Aztec Fuji” apple (Malus domestica Bork.) high-density orchard was studied over five years. Tilted trees with shortened arm configuration (TilShArm) always had significantly larger trunk cross-sectional area (TCSA) than Upright trees with an Overlapped arm configuration (UpOverArm) every year from 2012 to 2016. Trees with a TilShArm system had more cumulative fruit per tree than those with an Upright orientation. Trees with a tilted canopy (TilShArm and TilOverArm) tended to have higher yield per tree and yield per hectare than those with an upright system. Trees with a TilShArm system were more precocious and had more yield per tree than those with an upright canopy orientation in 2012. When values were polled over five years, trees with an upright canopy-shortened arm system (UpShArm) treatment had a lower biennial bearing index (BBI) than those with an upright canopy-overlapped system (UpOverArm). Trees receiving an arm shortening (UpShArm or TilShArm) configuration often had larger fruits than those with overlapped arms (UpOverArm and TilOverArm). Fruit from trees receiving an UpOverArm had higher fruit firmness than those from trees with other canopy-branch arrangements at harvest due to their smaller size. Fruit from trees with a TilShArm and TilOverArm had significantly higher water core and bitter pit but lower sunburn than trees with an upright canopy (UpShArm and UpOverArm). Leaves from trees with an UpOverArm canopy-branch configuration had the lowest leaf Ca but the highest leaf K and Fe concentrations among all treatments.展开更多

The ISERA f...This paper introduces the Integrated Security Embedded Resilience Architecture (ISERA) as an advanced resilience mechanism for Industrial Control Systems (ICS) and Operational Technology (OT) environments. The ISERA framework integrates security by design principles, micro-segmentation, and Island Mode Operation (IMO) to enhance cyber resilience and ensure continuous, secure operations. The methodology deploys a Forward-Thinking Architecture Strategy (FTAS) algorithm, which utilises an industrial Intrusion Detection System (IDS) implemented with Python’s Network Intrusion Detection System (NIDS) library. The FTAS algorithm successfully identified and responded to cyber-attacks, ensuring minimal system disruption. ISERA has been validated through comprehensive testing scenarios simulating Denial of Service (DoS) attacks and malware intrusions, at both the IT and OT layers where it successfully mitigates the impact of malicious activity. Results demonstrate ISERA’s efficacy in real-time threat detection, containment, and incident response, thus ensuring the integrity and reliability of critical infrastructure systems. ISERA’s decentralised approach contributes to global net zero goals by optimising resource use and minimising environmental impact. By adopting a decentralised control architecture and leveraging virtualisation, ISERA significantly enhances the cyber resilience and sustainability of critical infrastructure systems. This approach not only strengthens defences against evolving cyber threats but also optimises resource allocation, reducing the system’s carbon footprint. As a result, ISERA ensures the uninterrupted operation of essential services while contributing to broader net zero goals.展开更多

文摘While climate change impacts on ancient societies are well-documented,their adaptation mechanisms remain poorly understood.This study examines ancient Chinese architecture,specifically focusing on the abrupt decline in the use of projecting arms in bracket sets during the cold period from the 3rd to 6th centuries—a phenomenon known as the“Six Dynasties Bracket Mystery”—to explore how architectural forms responded to climatic shifts.Based on an analysis of approximately 250 cases of quasi-architectural evidence,we identify a five-stage variation in the presence ratio of projecting arms over approximately 700 years,beginning in the early 1st century.By integrating this quantitative variation with high-resolution paleoclimate reconstructions and experimental analysis,this study demonstrates that climate change,particularly the abrupt cooling events during the 3rd–6th centuries,altered the functional requirements of building eaves,leading to the decline of projecting arms.Our study provides a reasonable explanation for the longstanding puzzle concerning bracket sets in ancient Chinese architectural research,emphasizing environmental adaptation rather than aesthetic or technological considerations.It also highlights architectural adaptation as a material expression of human responses to climate change,offering insights into the interplay between climate,socio-historical context,and architecture in ancient China.

文摘This paper introduces the Integrated Security Embedded Resilience Architecture (ISERA) as an advanced resilience mechanism for Industrial Control Systems (ICS) and Operational Technology (OT) environments. The ISERA framework integrates security by design principles, micro-segmentation, and Island Mode Operation (IMO) to enhance cyber resilience and ensure continuous, secure operations. The methodology deploys a Forward-Thinking Architecture Strategy (FTAS) algorithm, which utilises an industrial Intrusion Detection System (IDS) implemented with Python’s Network Intrusion Detection System (NIDS) library. The FTAS algorithm successfully identified and responded to cyber-attacks, ensuring minimal system disruption. ISERA has been validated through comprehensive testing scenarios simulating Denial of Service (DoS) attacks and malware intrusions, at both the IT and OT layers where it successfully mitigates the impact of malicious activity. Results demonstrate ISERA’s efficacy in real-time threat detection, containment, and incident response, thus ensuring the integrity and reliability of critical infrastructure systems. ISERA’s decentralised approach contributes to global net zero goals by optimising resource use and minimising environmental impact. By adopting a decentralised control architecture and leveraging virtualisation, ISERA significantly enhances the cyber resilience and sustainability of critical infrastructure systems. This approach not only strengthens defences against evolving cyber threats but also optimises resource allocation, reducing the system’s carbon footprint. As a result, ISERA ensures the uninterrupted operation of essential services while contributing to broader net zero goals.

文摘This paper adopts the Global Workspace Theory as a neuro-scientifically plausible theory for developing conscious cognitive architecture.The Global Workspace Theory’s compatibility with the working mechanisms underneath human brains is enhanced by the implementation of different cognitive features based on this framework.Amongst the topics in the literature for intelligent systems,we start with attention,memory and learning mechanisms,and corresponding experiments are summarized here.We also discuss how other topics of cognitive robotics could be developed based on these three basic components,and their correlations.This provides a foundation for future long-term development of cognitive architectures of cognitive robots.The research in this paper follows the incremental research pathway for the architecture implementation,which is consistent with the Biologically Inspired Cognitive Architecture roadmap.
文摘The aim of this article is to present my interpretation of the holistic-phenomenological worldview in practice.This study demonstrates how this approach,as well as the planning process that I followed(a process fundamentally different from conventional ones)was implemented in a residential neighborhood I designed and built in the social,economic,and physical structure of the collective known in Israel as a‘kibbutz’.The intention is to raise a broad public discussion and pose a challenge to 21st-century architecture regarding how to intervene in a moral and human way within an existing environment,urban or natural,which must be respected and preserved,when integrating within it a new contemporary architecture.
文摘Overview of root system architecture.The plant root system is a highly dynamic and multifunctional organ system composed of primary roots,lateral roots,adventitious roots,and root hairs.Based on topological morphology,root systems can be classified as taproot systems or fibrous root systems.Root system architecture(RSA)refers to the spatial distribution and extension patterns of roots within soil,encompassing characteristics such as root length,branching angle,density,and spatial arrangement.RSA not only determines the plant’s capacity to acquire water and nutrients but also influences other root functions,playing a decisive role in overall plant health.
文摘Traditional architecture,as a crucial component of human cultural heritage,conveys significant historical context and cultural significance while reflecting regional traits and national identity.Nevertheless,in the face of rapid modernization,traditional architecture is encountering challenges on an unprecedented scale.This study focuses on examining the strategies for preserving and transforming traditional architecture.By evaluating the importance,issues,and obstacles associated with safeguarding traditional architecture,this paper seeks to propose effective and rational conservation approaches and transformation techniques,ultimately aiming to ensure the sustainable development and cultural continuity of traditional architecture.
