Seismic Assessment of Typical 1970s Tall Steel Moment Frame Buildings in Downtown San Francisco [PDF]

open access: yes, 2012
An inventory of the existing tall building stock in San Francisco revealed that most tall buildings in the city were built in the 1970s and 1980s and adopted a steel Special Moment Resisting Frame (SMRF) structural system.

Symbols and the bifurcation between procedural and conceptual thinking [PDF]

open access: yes, 2001
Symbols occupy a pivotal position between processes to be carried out and concepts to be thought about. They allow us both to d o mathematical problems and to think about mathematical relationships.

A Systematic Study of GelMA‐Carbopol Bioinks for High‐Fidelity Extrusion 3D Bioprinting at Physiological Temperatures

open access: yesAdvanced Healthcare Materials, EarlyView.
Gonzalez Martinez and collaborators develop a strategy to formulate high performance GelMA‐based bioinks with low solids contents. The resulting bioinks enable 3D bioprinting at 37 °C of high‐fidelity structures with tunable mechanical properties that support high cell viability and function.

Monolith formation and ring-stain suppression in low-pressure evaporation of poly(ethylene oxide) droplets [PDF]

open access: yes, 2012
When droplets of dilute suspensions are left to evaporate the final dry residue is typically the familiar coffee-ring stain, with nearly all material deposited at the initial triple line (Deegan et al, Nature, vol. 389, 1997, pp. 827-829).
