Fig. 1: The robot, shown here scratching one of the 20 surfaces used in the experiments. This study investigates the use of a vibrotactile sense for surface texture recognition by a humanoid robot. The sensor is an artificial fingernail with an attached 3-axis accelerometer, which the robot uses to scratch different surfaces. Our method combines frequency-domain analysis of the acceleration mea...

Because nail psoriasis is difficult to treat, therapy with many biological drugs has been attempted. Ustekinumab is approved for chronic plaque psoriasis and psoriatic arthritis (PsA), with some trials reporting nail improvement using this agent. A 51-year-old man with severe chronic plaque psoriasis had severe involvement of all fingernails and toenails, with accompanying nail fold psoriasis. ...

We report on a newborn male patient with a terminal deletion in the long arm of the chromosome 4 with a congenital heart defect unreported before in association with this syndrome. The patient had multiple congenital anomalies including a pointed duplicated fingernail, low set posteriorly rotated ears, large anterior fontanel, micrognathia, glabellar capillary vascular malformation, and Interru...

Onychopapilloma is a benign tumor of the nail bed and distal matrix and is the most common cause of localized longitudinal erythronychia. Here, we describe a case of onychopapilloma presenting as longitudinal leukonychia of the left 4th fingernail in a 71-year-old female. To date, this is only the ninth described case of onychopapilloma presenting as longitudinal leukonychia. We review the lite...

In this paper we report on new developments in the automatic meeting transcription task. Unlike other types of speech (such as those found in Broadcast News and Switchboard), meetings are unique in their richer dynamics of human-to-human interaction. An intuitive “fingernail” plot is proposed to visualize such turntaking behavior. We will also show how recognition of short turns can be improved...

Acute and chronic infections and inflammation adjacent to the fingernail, or paronychia, are common. Paronychia typically develops following a breakdown in the barrier between the nail plate and the adjacent nail fold and is often caused by bacterial or fungal pathogens; however, noninfectious etiologies, such as chemical irritants, excessive moisture, systemic conditions, and medications, can ...
