When the compressed profile is extracted from a land impression by averaging multiple surface profiles measured perpendicular to the striation direction, invalid areas may be encountered that are weakly striated and do not contain valid striation information.
Striving for a more cost-efficient laser cutting by accelerating the cutting speed increases the waviness of the laser cut surface and even causes deterioration in striation pattern, mainly at the lower cut edge.
When viewed from one perspective, the magic circle appears as a series of striations, a device designed to ensure successful completion of the game; when viewed from another, it appears as a smooth, multifaceted space which can develop and accommodate highly differentiated flows of desire in a positive, productive way.

Following Deleuze and Guattari, one might argue that not only are the Atonist efforts to striate all space unable to contain Jes Grew, but, ultimately, the effort at striation in this case has the reverse effect and actually "emits new smooth spaces" (500), or at least those spaces at the crossroads that defy the one-way logic the Atonists wish to impose on all peoples and places.
With oblique striation, the sarcomere compression zones overlap, the attachment sites are spread apart, and a more even loading pattern is generated within the basal lamina.
