Purpose Conjunctival adherence of a tick is an uncommon event with few reports previously cited in the literature. We report a unique case of tick penetration, specifically a black-legged deer tick (Ixodes scapularis), into the conjunctiva. Observations This patient experienced a 3-week history of unilateral mild ocular pain, decreased vision, and pigmented lesion of her right eye. Slit lamp ...

Abstract Purpose – This paper seeks to develop a novel legged robot. Design/methodology/approach – First, the paper models the legged robot using 3D computer model by intelligent inspiration of biological principles. Then, based on this model, it develops the prototype of the legged robot. Findings – A novel motion mechanism is used and only two actuators are used for driving the system. Origin...

A unified architecture for fast and efficient computation of the set of two-dimensional (2-D) transforms adopted by the most recent state-of-the-art digital video standards is presented in this paper. Contrasting to other designs with similar functionality, the presented architecture is supported on a scalable, modular and completely configurable processing structure. This flexible structure no...

This Paper is about landing control of legged robot. Body stiffness and damping is used as landing strategy of a legged robot. First, we only used stiffness control method to control legged robot landing. Second control method,sliding mode controller and feedback linearization controller is applied to enhance position control performance. Through these control algorithm, body center of gravity ...

It is well known that legged locomotion is more efficient,speedy, and versatile than the one by track and wheeled vehicles when it operates in a rough terrain or in unconstructed environment. The potential advantages of legged locomotion can be indicated such as better mobility, obstacles overcoming ability, active suspension, energy efficiency, and achievable speed (Song & Waldron, 1989). Legg...

OBJECTIVES To determine age- and sex-specific reference values for six physical performance measures, i.e. hand-grip strength, one-legged stance, and gait speed and step length at both usual and maximum paces, and to investigate age and sex differences in these measures among community-dwelling older Japanese adults. METHODS We conducted a pooled analysis of data from six cohort studies colle...
