Two-point discrimination (2PD) is the ability to discern that two nearby objects touching the skin are truly two distinct points, not one. It is often tested with two sharp points during a neurological examination [ 1 ] : 632 [ 2 ] : 71 and is assumed to reflect how finely innervated an area of skin is.
The average silhouette of the data is another useful criterion for assessing the natural number of clusters. The silhouette of a data instance is a measure of how closely it is matched to data within its cluster and how loosely it is matched to data of the neighboring cluster, i.e., the cluster whose average distance from the datum is lowest.

Acute or chronic disruption and/or attenuation of the ulnar collateral ligament often result in medial elbow pain, valgus instability, and impaired throwing performance. There are both non-surgical and surgical treatment options. [5]
The ulnar nerve is trapped between the bone and the overlying skin at this point. This is commonly referred to as bumping one's " funny bone ". [ 2 ] This name is thought to be a pun , based on the sound resemblance between the name of the bone of the upper arm, the humerus , and the word " humorous ". [ 3 ]
For the purpose of DBSCAN clustering, the points are classified as core points, (directly-) reachable points and outliers, as follows: A point p is a core point if at least minPts points are within distance ε of it (including p). A point q is directly reachable from p if point q is within distance ε from core point p. Points are only said to ...
Ulnar neuropathy at the cubital tunnel is diagnosed based on characteristic symptoms and signs. Intermittent or static numbness in the small finger and ulnar half of the ring finger, weakness or atrophy of the first dorsal interosseous, positive Tinel sign over the ulnar nerve proximal to the cubital tunnel, and positive elbow flexion test (elicitation of paresthesia in the small and ring ...
