Linear Strain Tensors on Hyperbolic Surfaces and Asymptotic Theories for Thin Shells
We perform a detailed analysis of the solvability of linear strain equations
on hyperbolic surfaces. We prove that if the surface is a smooth
noncharacteristic region, any first order infinitesimal isometry can be matched
to an infinitesimal isometry of an arbitrarily high order. The implications of
this result for the elasticity of thin hyperbolic shells are discussed
Summary statistics of student reactions and self-reported learning following the activity.
<p>Student affective and self-reported learning data were collected and pooled from five courses at three schools.

Changes in student perceptions about biology.
<p>Student survey data were collected in five independent sections of Introduction to Biology over two years (<i>n</i> = 195). Students were given a nine-question survey (upper panel) immediately before and following the activity. Questions 1–7 were selected for relevance from the CLASS-Bio survey [<a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.1002351#pbio.1002351.ref008" target="_blank">8</a>], while questions 8 and 9 were added to address issues that are specifically relevant to the activity but not present in CLASS-Bio. Expert responses are affirmative for questions 1–5 and 9, and negative for questions 6–8. Shifts in student responses were analyzed using a Wilcoxon signed-rank test. Individual test results with <i>p</i>-values less than 0.005 are indicated.

Rapid calculation of the risk to undergo a first APS event in the next 5 years of a previously symptomatic patient.
<p>The risk is based on the values of the three main risk factors. Moderate risk is marked in orange. high risk in red and very high risk in violet. The values in yellow are close to the cut-off point (10.6).</p
