craniotabes, circumscribed craniomalacia
A disease marked by the presence of areas of thinning and softening in the bones of the skull and widening of the sutures and fontanelles (soft membranous gaps between the incompletely formed cranial bones of a fetus or an infant). Usually of syphilitic (syphilis) or rachitic (rickets or bending of the bones) origin.
extenuating circumstances, extrordinary circumstances, mitigating circumstances
To render a crime less aggravated, heinous, or reprehensible than it would otherwise be, or to tend to palliate or to lessen its guilt.

Such circumstances may ordinarily be shown in order to reduce a punishment or damages. In contract law, unusual or extraordinary events that prevent performance within a specified time; for example, a delay resulting from a strike by workers or suppliers.

morphea, morphoea; Addison's keloid, circumscribed scleroderma, localized scleroderma
A skin disease consisting of patches of yellowish or ivory-colored hard, dry, smooth skin.
nanocircuit, nanocircuitry
A computer circuit built on a single and assembled on a single carbon nanotube.

The circuit is one-fifth the width of a human hair and can only be viewed under an electron microscope.

The circuit is not designed to be used in a computer chip; instead, it is a proof of the principle that allowed the research team to test the switching speed of its design.

Using this setup, researchers have claimed that they could achieve a speed of 50 megahertz, hundreds of times slower than the gigahertz speeds of silicon processors seen in most personal computers. Even so, the researchers say the circuit is 100,000 times faster than any previously recorded for a device made with a carbon nanotube, and with continued refinement they hope to push speeds beyond those possible today.

Recently reported results indicate that across the main radiation environments, including heavy ion, total dose and proton irradiation, different types of nanoscale materials and circuits may outperform their conventional counterparts.

In each case, the improvement was traced to the use of a nanoscale functional entity and its apparent radiation resiliency. These results indicate that the research direction of fundamental radiation interactions in nanoscale materials is well worth pursuing.
