# s-gst: periodic stripes: spacing and orientation

<< Patterning of periodic stripes during development requires mechanisms to control both stripe spacing and orientation. A number of models can explain how stripe spacing is controlled, including molecular mechanisms, such as Turing’s reaction-diffusion model, as well as cell-based and mechanical mechanisms >>

The Hiscock and Megason's  master model << predicts three main perturbations that can affect how stripes orient: one is a change in "production gradient," which would be a substance that amplifies stripe pattern density; second is a change in "parameter gradient," a substance that changes one of the parameters involved in forming the stripe; and the last is a physical change in the direction of the molecular, cellular, or mechanical origin of the stripe >>

# n-trade: the gross national product does not allow for

<< Yet the gross national product does not allow for the health of our children, the quality of their education or the joy of their play.  It does not include the beauty of our poetry or the strength of our marriages, the intelligence of our public debate or the integrity of our public officials.  It measures neither our wit nor our courage, neither our wisdom nor our learning, neither our compassion nor our devotion to our country, it measures everything in short, except that which makes life worthwhile.  And it can tell us everything about America except why we are proud that we are Americans. >>

# e-sec: Sun Tzu style: unpredictable (chaotic) environment to defending cpu from cyber-attacks

<< We want our computers to perform the way we expect. But what if the key to defeating malware is introducing a bit of chaos? >>

<< Programs you know and trust could be approved to run in a standard environment where they'll function normally, while detected malware are sequestered in a third environment, called deceptive. Instead of squashing them immediately, Chameleon would let the malicious processes continue to work in a façade environment while collecting information that can be used to understand and defeat them >>
