Traveling Mermaids, Traveling Materials

Journal for the History of Knowledge
This article—which is mostly based on secondary literature following the questions suggested by a visit to the Victoria & Albert Museum—proposes how a decentering of the history of knowledge can be achieved by thinking with museum objects.

Symmetry‐Guided Multifunctional Acoustic System Based on Mechanically Actuated Sonic Crystals

Advanced Engineering Materials, EarlyView.
This study presents the design, simulation, and experimental validation of amultifunctional acoustic metamaterial based on rotationally engineered sonic crystals.By tuning cylinder orientations, controllable band gaps and six distinct functionalities—including switching, topological insulation, beam splitting, and logic operations—areachieved ...

Iterative Patching and the Asymmetric Traveling Salesman Problem [PDF]

Although Branch and Bound (BnB) methods are among the most widely used techniques for solving hard problems, it is still a challenge to make these methods smarter.

Travel to Work, Travel to Play: On Russian Tourism, Travel, and Leisure [PDF]

Slavic Review, 2003
In the introduction to this special issue, Diane P. Koenker discusses the interrelated categories of travel, tourism, and leisure, looking at contrasting definitions of the traveler and the tourist and situating Russian and Soviet experience in a broader literature. Among the themes raised in the issue's articles, she enumerates the quest for knowledge

Model‐Guided Design of Paper Membrane Architectures for Controlled Flow and Enhanced Diagnostic Sensitivity

Advanced Engineering Materials, EarlyView.
Geometrical modifications on nitrocellulose membranes can result in observable differences in signal intensity relative to a reference membrane (top and bottom left). Using two reference experiments, we have developed a theoretical model that can reproduce the experimentally observed flow changes and provide information on membrane parameters, e.g ...

An empirical investigation into randomly generated Euclidean symmetric traveling salesman problems [PDF]

The traveling salesman problem is one of the most well-solved hard combinatorial optimization problems. Any new algorithm or heuristic for the traveling salesman problem is empirically evaluated based on its performance on standard test instances, as ...

Enhanced Ultrasound Transmission Through Aberration Layers Using Space‐Coiling Acoustic Metamaterials

Advanced Engineering Materials, EarlyView.
Enhancing ultrasound transmission through an aberration layer exhibiting mismatched impedance with the surrounding medium possesses great implications in imaging and treatment. In this study, we show that a space‐coiling acoustic metamaterial with judiciously tailored structural profile can help improve impedance matching.
