Finger vein recognition has been considered one of the most promising biometrics for personal authentication. However, the capacities and percentages of finger tissues (e.g., bone, muscle, ligament, water, fat, etc.) vary person by person. This usually causes poor quality of finger vein images, therefore degrading the performance of finger vein recognition systems (FVRSs). In this paper, the in...

Thermal feedback has been proven to enhance user experience in human-machine interactions. Yet state-of-the-art thermal technology focused on the single finger or palm static contact, overlooking dynamic and multi-finger The underlying challenges include incompatible designs of conventional interfaces for providing salient stimuli such interactions and, thereby, a lack knowledge human perceptio...

abstract   background: the pathophysiology of carpal tunnel syndrome is associated with increased intracarpal canal pressure. recently, palmaris longus has been introduced as an independent risk factor for the development of carpal tunnel syndrome. the purpose of this study was to assess the association of carpal tunnel syndrome with the presence of palmaris longus tendon and functional superfi...

background : vaginismus is an involuntary spasm of the muscles of the outer third of the vagina caused by real or anticipated attempt of vaginal penetration.  it could lead to marital disharmony, guilt feeling and depression.  cognitive behavioral models for therapy of this disorder have gained considerable attention during last three decades.   objective: to determine the efficacy of self-fing...

background:  giant cell tumor of tendon sheath (gctts) is often thought of as a volar finger mass. we hypothesized that gctts are equally common on the dorsal and volar aspects of the hand. in addition, we hypothesized that there are no factors associated with the location (volar versus dorsal) and largest measured dimension of a gctts.  methods:  a total of 126 patients with a pathological dia...

The influence of the cerebellum on independent finger control has rarely been investigated. We examined multidigit control in 22 patients with cerebellar degeneration, 20 patients with cerebellar stroke, and 21 patients with surgical lesions after cerebellar tumor removal. In the first task, either the index finger or the middle finger was actively lifted from an object during static holding. B...

The finger-vein biometric offers a higher degree of security, personal privacy and strong antispoofing capabilities than most other biometric modalities employed today. Emerging privacy concerns with the database acquisition and lack of availability of large scale finger-vein databases have posed challenges in exploring this technology for large scale applications. This technical report details...

Problem statement: Underactuated finger mechanism is beneficial in the anthropomorphic applications in which it reduces the finger size, weight and power consumption due to the less number of actuators compared to its number of Degree Of Freedom (DOF). However, the currently existing underactuated finger is limited to grasping operations only and unable to pinch with the finger tip. Moreover, t...

Although acrometastases are rare but clinically they are considered important. Their etiology is quite different from the metastases to other sites; bronchogenic carcinoma is by far the most frequent case. The prognosis is always similar to metastatic bronchial cancer with an average survival of three mo...

BACKGROUND AND AIM: Thumb sucking has been reported as one of the etiologic factors for malocclusion. The aim of this study was to determine the prevalence of thumb sucking and use of different kinds of habit breaker (HB) appliances in children attending private kindergartens in Kerman, Iran.METHODS: The census method was used in the present cross-sectional study, and the study population consi...
