Lightweight Metal–Polymer Interpenetrating Phase Composites for Mechanical Reinforcement and Absorption‐Dominant Electromagnetic Interference Shielding

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT The pursuit of multifunctional lightweight materials with electromagnetic interference (EMI) shielding of low reflection, programmable architecture, and robust mechanical performance presents both significant opportunities and challenges. In this work, aluminum (Al)‐alloy lattice with 90% porosity was designed and fabricated using additive ...

Non‐Physical Barrier Design and Environmental Conditions Alter Routing and Survival of Juvenile Chinook Salmon (Oncorhynchus tshawytscha) in the Sacramento‐San Joaquin River Delta

open access: yesRiver Research and Applications, Volume 42, Issue 7, Page 1551-1561, September 2026.
ABSTRACT Pacific salmon face substantial challenges when migrating through anthropogenically modified river systems, such as the Sacramento‐San Joaquin River Delta (the Delta). Non‐physical behavioral barriers, such as the bioacoustic fish fence (BAFF), are one potential solution for guiding fish away from hazards without obstructing water flow ...

Portable Radar for Noncontact Heart Rate Monitoring and Estrus Detection in Dairy Cows

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, Volume 21, Issue 9, Page 1390-1403, September 2026.
This study introduces a portable radar system for real‐time monitoring of respiratory and heart rates in dairy cows. It uses millimeter‐wave Frequency Modulated Continuous Wave (FMCW) radar to perform noncontact physiological sensing, reducing behavioral disturbance. The radar system's design prioritizes portability, cost‐effectiveness, and robustness,

Preemptive Entry and Technology Diffusion: The Market for Drive‐In Theaters

open access: yesThe RAND Journal of Economics, Volume 57, Issue 3, Page 471-494, Autumn (Fall) 2026.
ABSTRACT This article studies entry preemption in new industries. We first test a key prediction of dynamic entry games: Entry preemption is most relevant in intermediate‐sized markets, where firms face highest uncertainty about future entry. Using US drive‐in theater market (1945–1957) data, we find robust evidence for this non‐monotonic relationship ...

A QUBO Formulation for Multi‐Material Topology Optimization With Quantum Annealing

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 16, 30 August 2026.
ABSTRACT Multi‐material topology optimization (MMTO) seeks the optimal distribution of multiple materials within a given design domain to maximize structural performance. However, due to the high complexity of the solution space, MMTO problems are often trapped in local optima. To address this issue, a quantum annealing‐based MMTO framework is proposed.

Multi-objective design optimization of geometrically nonlinear truss structures

open access: yes, 2012
The design optimization of geometrically nonlinear truss structures has been carried out generally by utilizing a single objective function (weight of truss structure and etc.) and an optimality criterion (uniform strain density distribution among truss ...

Cross_section and reinforcement optimization of roof truss

open access: yes
The thesis is focused on optimization of cross-section shape of reinforced concrete truss. An optimization algorithm was created in Microsoft Office Excel which optimizes the shape and reinforcement of the reinforced concrete truss. The truss is as cheap
