Why morphology matters in birds and UAV's: How scale affects attitude wind sensitivity

Why and How Technology Matters

Technology matters. Bicycles were instrumental in the political and social emancipation of women (Bijker 1995); photo and film technology induced a subtle form of apartheid (Wajcman 2005); nuclear arms and energy shaped, for example through the non-proliferation treaty, international relations since the 1950s (Smit 2005); the low-hanging overpasses on Long Island discourage since the 1920s the ...

Reflection in Nursing Education: Why and How?

Introduction: Nursing education should develop autonomy, critical thinking, open-mindedness and sensitivity to others. Reflection seems to be an effective strategy for developing such capabilities in nursing. Therefore, this narrative review study was carried out to explore reflection in nursing education. Methods: Using keywords like reflecting, reflection and nursing reflection, FarsiandEngl...

How It Works and Why It Matters

This paper provides simulation practitioners and consumers with a grounding in how discrete-event simulation software works. Topics include discrete-event systems; entities, resources, control elements and operations; simulation runs; entity states; entity lists; and entity-list management. The implementation of these generic ideas in AutoMod, SLX, and Extend is described. The paper concludes w...

Why Learning How to Chase Butterflies Matters: A Response to Recent Commentaries

Morphology matters in immune cell chemotaxis: membrane asymmetry affects amplification.

A key mediator of eukaryotic chemotaxis is the asymmetric accumulation of phosphatidylinositol-3,4,5-triphosphate (PIP3) on the cell membrane. Recent work has focused on understanding how a shallow external gradient of chemoattractant leads to an amplified internal gradient of PIP3. In this paper we dissect what fraction of this amplification is derived biochemically by the signal transduction ...
