This paper presents the design and analysis of a liquid refractive index sensor that utilizes a unique physical mechanism of resonant optical tunneling effect (ROTE). The sensor consists of two hemicylindrical prisms, two air gaps, and a microfluidic channel. All parts can be microfabricated using an optical resin NOA81. Theoretical study shows that this ROTE sensor has extremely sharp transmis...

We describe two acalculic patients, one with a left subcortical lesion and the other with a right inferior parietal lesion and Gerstmann’s syndrome. Both suffered from “pure anarithmetia”: they could read arabic numerals and write them to dictation, but experienced a pronounced calculation deficit. On closer analysis, however, distinct deficits were found. The subcortical case suffered from a s...

Ninety-two subjects solved a series of problems without enough time to finish and worked either at a pace and in an order determined by the experimenter (experimenter-paced) or at their own pace and order under self-administered time deadlines (self-paced). Self-pacing resulted in superior performance on rote and poorer performance on cognitive problems relative to experimenter-paced groups. Se...
