A Century of Understanding and Harnessing Heterosis

Plant Breeding, EarlyView.
ABSTRACT Heterosis has shaped modern plant breeding since Darwin's 19th century observations that outcrossing restores vigour lost through selfing. While 100 years old, its mechanistic basis and deployability remain actively debated. Classical models of dominance, overdominance and epistasis provided the foundation for hybrid breeding and converted ...

Simulated Annealing for the Optimization of Trusses

, 2008
The Simulated Annealing (SA) Technique belongs to a Stochastic Optimization class of algorithms. This technique has been used as a soft computing technique in hard optimization tasks, such as, electronic components allocation, spatial representation of chemical compounds and Traveling Salesman type problems, for a long period.

Maximum‐Entropy‐Based Meshless Modeling of Surface‐Tension‐Driven Large Deformation

International Journal for Numerical Methods in Engineering, Volume 127, Issue 17, 15 September 2026.
ABSTRACT Soft material modeling is challenging due, among others, to the substantial structural changes these materials undergo. In this context, meshless methods offer a promising alternative to overcome the limitations of established mesh‐based approximations such as finite elements. However, they introduce new challenges.

Development of Hamiltonian for Structural Applications by Quantum Annealing Assuming Finite Element Method

International Journal for Numerical Methods in Engineering, Volume 127, Issue 17, 15 September 2026.
ABSTRACT Quantum annealing is emerging as a practical tool for large‐scale combinatorial optimization. We map continuum displacements and element densities to binary variables, turning both deformation analysis and topology optimization into quadratic unconstrained binary optimization (QUBO) problems that run on today's annealers.

A Structured Virtual Reality Laboratory Methodology for Teaching Structural Mechanics to Undergraduate Engineers

Computer Applications in Engineering Education, Volume 34, Issue 5, September 2026.
ABSTRACT Developing spatial and physical intuition for structural behaviour is a central challenge in undergraduate engineering education, and virtual reality (VR) offers a compelling medium for addressing it through immersive, interactive exploration. However, most published research focuses on the design of VR platforms, with limited attention to how

World's First Hybrid WAAM Steel 3D Truss – An Imperial‐MX3D Demonstrator

ce/papers, Volume 9, Issue 2-3, Page 555-560, September 2026.
Abstract Traditional steel construction is limited in its ability to deliver optimised structural forms and remains labour‐intensive in the fabrication of intricate components. Wire arc additive manufacturing (WAAM) offers high geometric freedom and construction automation; however, fully additively manufactured steel structures remain constrained by ...
