The topographical features of fractured tensile, flexural, K1C, and impact specimens of monolithic epoxy have been studied and correlated with mechanical properties and surface features of samples before fracture. The topographical features studied include waviness (Wa), roughness average (Ra), root mean square value (Rq), and maximum roughness height (Rmax or Rz). As surface notches generate t...

handsome contribution. In Ireland's time the subject was still emerging from the anecdotal and even mythological stage. It is largely due to the efforts of Dr. Tredgold that the topographical outlines of mental deficiency have been filled in. I say topographical advisedly for, despite much revision and the addition of new and valuable material, the book still bears the imprint of having been wr...

Analysis of categorical data is a challenging task. In this paper, we propose to compute topographical features of high-dimensional categorical data. We propose an efficient algorithm to extract modes of the underlying distribution and their attractive basins. These topographical features provide a geometric view of the data and can be applied to visualization and clustering of real world chall...

The Topographical Collection of King George III—known as the “K. Top. collection”—includes maps, views, architectural drawings, atlases, sea charts, and counts one world’s most significan...

Topographical representation of the visual field within striate cortex of primates has been demonstrated by a number of methods. In man, visual field deficits have ~ been related to cortical lesions1o,27 and the perceived positions of evoked sensations have been related to sites of electrical stimulation2. In monkeys anterograde or retro~ grade degeneration techniques have been used to determin...

Neurons in layer IV of the rodent whisker somatosensory cortex are tangentially organized in periodic clusters called barrels, each of which is innervated by thalamocortical axons transmitting sensory information from a single principal whisker, together forming a somatotopic map of the whisker pad. Proper thalamocortical innervation is critical for barrel formation during development, but the ...

When preparing to perform a task, the brain settles into task-set states which are relevant for the selection of the appropriate task-rules and stimulus-response mappings. The way this selection takes place within the Language domain is not well understood. We used high-density electrophysiological recordings while participants were engaged in a task in which cues directed their attention to th...
