New Ways of Thinking about Freight Data

ITE JOURNAL / DECEMBER 2004 INTRODUCTION The incorporation of intelligent transportation systems (ITS) into goods transport promises to increase productivity, security and efficiency. This feature reviews emerging examples of “passive” data collection efforts in several states. Work remains to transform these opportunities into needs identified by freight planners and researchers. Freight movem...

Some Ways of Thinking Algorithmically About Impossibility1

I argue that some progress can be made by (very deliberately) thinking algorithmically about lower bounds. Slightly more precisely, to prove a lower bound against some class C of programs, we can start by treating C as a set of inputs to another (larger) process, which is intended to perform some basic analysis of programs in C. By carefully studying the algorithmic “meta-analysis” of programs ...

New Ways of Thinking About Senescent Bioprosthetic Heart Valve Therapy.

SEE PAGE 1735 I n patients requiring heart valve replacement, biologic valve substitutes have been implanted with increasing frequency over the past decade. According to the Society of Thoracic Surgeons (STS) database, bioprosthetic valve implants in the aortic position have increased from 43.6% in 1997 to 78.4% in 2006 (1). A similar trend has been seen for mitral valve replacement (2). The tr...

Potential “ways of thinking” about the shear-banding phenomenon

Shear-banding is a curious but ubiquitous phenomenon occurring in soft matter. The phenomenological similarities between the shear-banding transition and phase transitions has pushed some researchers to adopt a ‘thermodynamical’ approach, in opposition to the more classical ‘mechanical’ approach to fluid flows. In this heuristic review, we describe why the apparent dichotomy between those appro...
