Fuzzy functional dependency (FFD) is a kind of semantic knowledge and can be discovered from a large volume of business data. Sectional FFD and Attribute FFD are discussed so as to reflect semantics of the business world and express useful information that is natural for people to comprehend. The experimental results on an insurance data set show that the proposed method can extract knowledge e...

Orbital fat is the soft tissue inside the eye socket, or orbit, that surrounds the eye muscles, eyeball, optic nerve and blood vessels. It plays an important role in the mechanical operation of the eye during eyeball rotation. Knowledge of how this orbital fat behaves is limited. It is important for surgeons to improve this knowledge to make better informed decisions before and during eye surge...

Background: Hallux valgus the most common forefoot deformity stretches the medial cutaneous nerve. There is a paucity of information regarding neuropathy associated with this often-progressive deformation. Methods: The current study involves two groups: 30 patients examined prior to hallux valgus surgery and 30 foot surgery candidates without hallux valgus that were scheduled for a different op...

Nerve root deformation magnitude affects behavioral sensitivity and spinal cytokine expression in a lumbar radiculopathy model. Despite evidence suggesting spinal glia play a role in persistent pain, no study has examined the relationship between injury severity in painful radiculopathy and spinal glial activation. This study quantified local in vivo biomechanics for nerve root injury, describi...

PURPOSE Visual impairment and intracranial pressure (VIIP) syndrome is a health concern for long-duration spaceflight, and a proposed risk factor is elevation of intracranial pressure (ICP). Our goal was to use finite element modeling to simulate how elevated ICP and interindividual differences affect tissue deformation within the optic nerve head (ONH). METHODS We considered three ICP condit...

background: two main muscles studied in the hand for evaluation of median nerve injuries are opponens pollicis (op) and abductor pollicis brevis (apb). however, riché-cannieu communicating branch (rccb) may limit the use of these muscles in electrodiagnosis. this condition is confusing in the case of median nerve injuries. this study was conducted to evaluate the prevalence of rccb.   methods: ...
