To mitigate these constraints, a two-phase hybrid lattice structure with modular assembly capability has been developed. This design allows for reconfiguration based on load conditions and functional requirements. We conduct experimental investigations to characterize the mechanical properties of three novel configurations: the asymmetric re-entrant lattice, the bionic lattice, and their hybrid structure. The results indicate that the hybrid lattice demonstrates improved specific energy absorption and exhibits more diversified and flexible properties compared to the conventional single lattice structure. The specific energy absorption and effective Young's modulus of the double asymmetric re-entrant lattice are improved by 32.8 % and 128.36 %, respectively, when compared to benchmark re-entrant lattice.

However, existing greenhouse systems, often designed for temperate climates, struggle to cope with the thermal and hydric stresses that characterize dryland environments, including arid, semi-arid, and Mediterranean zones. This prospective review presents a systems-level framework for climate-resilient greenhouse design, emphasizing the integration of structural optimization, passive and hybrid cooling strategies, advanced glazing materials, desalination-enabled water reuse, and aquaponics-based biological cycling. Key leverage points include orientation-driven thermal mitigation, membrane-based desalination powered by renewable energy, and decoupled aquaponics systems enabling a precise and climate-smart approach to environmental control. Emerging innovations in evaporative and desiccant hybrid cooling, spectral selective and radiative films, and nutrient-selective electrodialysis further enhance the potential of integrated solutions. The paper highlights how materials science, thermofluid dynamics, and engineering can be harmonized to improve crop productivity, resource efficiency, and climate adaptability in greenhouse production for dryland settings. Rather than viewing cooling, irrigation, and biological production as discrete challenges, the review advocates for interdependent subsystem designs that close thermal, hydric, and nutrient loops within a unified bioclimatic envelope. A circular conceptual framework illustrates these synergies and guides future greenhouse development in water and energy-stressed drylands. By reframing the greenhouse as a regenerative infrastructure, this study outlines a blueprint for an integrated food–water–energy nexus able to operate efficiently and sustainably in the world's most vulnerable agricultural zones.</div></div>","PeriodicalId":36919,"journal":{"name":"Results in Engineering","volume":"28 ","pages":"Article 107035"},"PeriodicalIF":7.9,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145119433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this ongoing threat, we present AndroMD, an intelligent and scalable Android malware detection framework that combines automated dataset construction, optimal feature selection, and ensemble-based classification. The proposed framework is built on three core components. First, an automated pipeline processes over 600,000 APKs to extract static features from more than 140 million Java files and 600,000 manifest files, resulting in three distinct datasets: KeyCount, ZeroOne, and MNF. These datasets are constructed using keys and patterns derived from a detailed analysis of real decompiled malware code, ensuring semantic relevance. Second, we introduce the AndroMD Optimal Feature Selection (AOFS) method, which selects compact, high-performing feature subsets using iterative evaluation based on ensemble feedback. Third, an ensemble detection model combines Random Forest, Decision Tree, and Bagging classifiers, with a threshold-based aggregation mechanism that allows fine-grained control over detection sensitivity. Extensive evaluation demonstrates AndroMD's strong performance, achieving up to 99.88% accuracy on internal datasets and 91.66% accuracy in live testing, including detection of custom and zero-day malware samples. AndroMD also identifies threats overlooked by VirusTotal, showcasing its real-world applicability.
