Development of frame finite element model for truss structures with semi-rigid connections
Engineering and Applied Science Research, 2018 The problem of connecting truss structures is one of the major concerns in structural analysis and design. The behavior of truss structures is usually analyzed using a common finite element model, which considers each member as a two-force member.

Cycle and flow trusses in directed networks [PDF]
Royal Society Open Science, 2016 When we represent real-world systems as networks, the directions of links often convey valuable information. Finding module structures that respect link directions is one of the most important tasks for analysing directed networks.

, 2023 A ring is one of the most essential structures in abstract algebra. There exist rings in the evolution of abstract algebra that contain "abnormal" members, particularly nilpotent elements. The existence of radicals of rings was inspired by this.

Load Distributing Metamaterials Via Discrete Optimization
Advanced Functional Materials, EarlyView.Mechanical metamaterials are computationally optimized to homogenize transmitted forces by minimizing the spread of reaction forces. The resulting architectures transform localized loading into broader, more uniform force distributions and experimentally demonstrate robust load spreading under quasi‐static and impact loading.

Embedded Direct Ink Writing of Thermoset and Elastomeric Polymers via Frontal Polymerization
Advanced Functional Materials, EarlyView.Embedded frontal polymerization direct ink writing (FP‐DIW) combines frontal ring‐opening metathesis polymerization with embedded 3D printing to decouple deposition from curing. A yield‐stress support bath stabilizes low‐viscosity inks, while on‐demand thermal initiation enables controlled front propagation. This approach expands the accessible feature

Truss structure optimization of heavy-duty escalators via finite element analysis.
PLoS ONETo adapt to the characteristics of high load and long-term operation of heavy-duty escalators, traditional trusses often adopt redundant structural designs to meet higher safety and reliability requirements, resulting in increased self-weight and higher ...

Advanced Science, EarlyView.A DLN dataset was built to analyze MABS composition versus in vitro/in vivo osteogenesis and angiogenesis. An MLP neural network, taking BG morphological parameters as input, extracts bioactive features from these datasets. A rabbit tibial defect model then validates 4D‐printed MABS for adaptability and bone regeneration in critical defects.
