This paper presents a glove designed to assess the viability of communication between a deaf-blind user and his/her interlocutor through a vibrotactile device. This glove is part of the TactileCom system, where communication is bidirectional through a wireless link, so no contact is required between the interlocutors. Responsiveness is higher than with letter by letter wording. The learning of ...

In this paper we propose an easy algorithm for real time hand finger counting involving one or more than one hand. Hand finger counting is a simple medium for Human-Computer Interface which can prove to be a convenient input method for driving interactive menus, small applications and interactive games. Here, we also calculate the orientation of the hand which can be used to provide inputs for ...

We present a photoacoustic computed tomography investigation on a healthy human finger, to image blood vessels with a focus on vascularity across the interphalangeal joints. The cross-sectional images were acquired using an imager specifically developed for this purpose. The images show rich detail of the digital blood vessels with diameters between 100 μm and 1.5 mm in various orientations and...

Zinc-finger proteins (ZFPs) are the largest transcription factor family in human genome. They have recently become an area of intense study because of their broad range of biological functions, including development, differentiation, metabolism, autophagy, cancer progression and more recently because they are attractive targets for antiviral therapy [1]. The zinc fingers was first recognized as...

What precursor abilities form the building blocks of numerical representations? Two abilities were investigated: the ability to mentally represent small numerosities, indexed by subitizing speed (Butterworth, 1999), and the ability to mentally represent one’s fingers, indexed by finger gnosis (Butterworth, 1999; Penner-Wilger & Anderson, 2008). We examined the longitudinal relation between thes...

The Pygo-BCL9 complex is a chromatin reader, facilitating β-catenin-mediated oncogenesis, and is thus emerging as a potential therapeutic target for cancer. Its function relies on two ligand-binding surfaces of Pygo's PHD finger that anchor the histone H3 tail methylated at lysine 4 (H3K4me) with assistance from the BCL9 HD1 domain. Here, we report the first use of fragment-based screening by N...

The extensor indicis is a narrow, elongated skeletal muscle in the deep layer of the dorsal forearm that originates from the one third of the distal posterior surface of the shaft of ulna below the origin of the extensor pollicis longos and interosseous membrane. It runs through the fourth tendon compartment with the extensor digitorum under the extensor retinaculum. The extensor indicis joins ...

This paper presents a methodology to perform a fine manipulation task with an anthropomorphic hand. We focus here on a three-finger precision grasp. The robotic hand used is the latest four finger fully actuated hand developed by the RoBioSS team of PPRIME institute. Different steps ranging from the generation of the contact points of the hand with the object to the experimental realization of ...

Local Anesthesia is performed via drugs administrated subcutaneously for narcotizing small areas (finger, small skin cuts etc.). With this method, patient relaxation is provided through intravenous relaxing drugs. It is simple, easy to apply and less risky method. It is the best method for managing the pain in small surgical procedures. The patient may be discharged just after the operation. Th...
