A Thoma, I Alexopoulou. Circumferential little finger nailplate. Can J Plast Surg 1995;3(3):161-162. This is a case report of a seven-year-old female who presented with a congenital anomaly of the little finger in which the nailplate was circumferentially covering the tip of the distal phalanx. There was a well-developed eponychial fold on the palmar aspect of the digit. This rare congenital `c...

In touch as in vision, perceptual acuity improves with training to an extent that differs greatly across people; even individuals with similar initial acuity may undergo markedly different improvement with training. What accounts for this variability in perceptual learning? We hypothesized that a simple physical characteristic, fingertip surface area, might constrain tactile learning, because p...

The focus of this research is to analyse both human hand motion and force, during eating, with respect to differing food characteristics and cutlery (including a fork and a spoon). A glove consisting of bend and force sensors has been used to capture the motion and contact force exerted by fingers during different eating activities. The Pearson correlation coefficient has been used to show that...

A two years old male child was referred from the child health department with a two month history of recurrent bleeding per rectum. The child was seen in multiple consultations elsewhere and extensively investigated to rule out gastrointestinal as well as bleeding disorders. During psychiatric interview, mother reported that she induced the rectal bleeding by injuring the rectal mucosa using he...

We examine the evolution of an Ising ferromagnet endowed with zero-temperature single spin-flip dynamics. A large droplet of one phase in the sea of the opposite phase eventually disappears. An interesting behavior occurs in the intermediate regime when the droplet is still very large compared to the lattice spacing, but already very small compared to the initial size. In this regime the shape ...

Nonionized media subject to strong fields can become locally ionized by penetration of finger-shaped streamers. We study negative streamers between planar electrodes in a simple deterministic continuum approximation. We observe that, for sufficiently large fields, the streamer tip can split. This happens close to the limit of "ideal conductivity." Qualitatively, the tip splitting is due to a La...

A new method to extract vein patterns from an unclear finger image is proposed. Finger vein pattern can be used for personal identification technology. The finger vein image that is captured with infrared light contains not only the vein patterns but also irregular shades and noises. They result from the different thickness between finger bones and muscles and, light intensity fluctuations also...

A 61-year-old female suffered from disseminated joint pain (both hands, elbows, knees, ankles) with a prominent Raynaud phenomenon in both hands for 4 months before admission due to nausea. Acute kidney failure of unknown origin was diagnosed and acral cyanosis of fingers II–IV of the left hand with beginning finger tip necrosis became Fig. 1. Left hand at admission.
