Large language models (LLMs) make it possible to build knowledge graphs from professional literature at scale, but how such graphs fail at that scale is rarely measured. We built \sys{}, a cross-media knowledge graph of swine, aquaculture, tomato, maize and rice production, and analysed its 199,418...

This paper presents a genetic algorithm (GA)-tuned sliding mode controller for a quadcopter (QuCo) in which the sliding surface is built from a proportional-fractional-order-integral-derivative (PFOID) error function (PFOID-SMC). The aim is to achieve accurate trajectory tracking in the presence of...

Fine-grained plant disease classification requires separating classes of the same crop that often differ only in small, sparse lesion patterns. Looped Vision Transformers (LoopViTs) obtain depth by applying a small stack of weight-tied blocks repeatedly, yet each block rebuilds its attention graph f...

Modern precision agriculture is undermined by data scarcity, privacy concerns, and high latency in remote areas, and centralized AI models struggle to forecast rare, climate-induced crop stresses given insufficiently diverse datasets and stakeholders' reluctance to share sensitive data. To address t...

Expert advice on crop management is often written informally, and in such text a number can easily be assigned the wrong role or attached to the wrong operation, material, or measurement basis. We propose QS-IE, a knowledge extraction method constrained by quantity and operation scope. Its unit of e...

Comparative studies of machine learning classifiers for Land Use Land Cover (LULC) mapping often recommend one algorithm, yet their validation pixels are usually drawn from a few hand-digitised polygons and are far from independent. This study tested whether such differences survive that dependence....

Plant electrical signals are fast electrophysiological responses to environmental stimuli, physiological regulation and stress. Because they often change before visible symptoms appear, they are attractive indicators for early plant-health monitoring and for sensing in precision agriculture. Researc...

Slope stability prediction is a critical challenge in geotechnical engineering. This challenge arises from the complex nonlinear interactions among multiple influencing factors such as soil properties, slope geometry, and hydraulic conditions. Traditional analytical methods rely on simplified assump...

The Abel differential equation of the first kind has no general closed-form solution, and most recent results on its rational solutions give upper bounds on their number or describe qualitative properties. This paper describes a direct algebraic procedure for finding rational solutions when the coef...

Odyssey 15.69-71 has Menelaus advise Telemachus that a host who loves or hates a guest to excess is worse than one who observes αἴσιμα (aisima; `due measure'), a word usually rendered as measure, balance or moderation. Read against the vocabulary of modern optimisation, the passage can look like an...
