We evaluated the specific pattern of pre- and postoperative neurological signs and symptoms of cervical spondylotic myelopathy (CSM) to determine [mdings which had a predictive value for surgical outcome. Consecutive patients with CSM caused by osteophytic ridge or intervertebral disc herniation who underwent anterior cervical decompression and fusion in Loghman Hakim Hospital from 1999-200...

Neuroblastoma is an uncommon malignant neoplasm that derives from neural crest progenitor cells that normally give rise to the sympathetic nervous system. It represents 8 to 10% of all extracranial tumors in childhood. The purpose of this paper is to report a case in which a mandibular soft tissue mass was the initial presenting sign of disseminated neuroblastoma in a 2-year-old child, and to d...

We consider the following general optimization problem min x2≤1 −x ⊤ y + γx 1. (15) Before we proceed, we need the following lemma. Lemma 6. The solution to the optimization problem min x 1 2 (x − y) 2 + γ|x| is given by P γ (y) = 0, if |y| ≤ γ; sign(y)(|y| − γ), otherwise. where P γ (·) is the soft-thresholding operator defined in (7) (Donoho, 1995).

Multifocal fibrosis is a rare condition occurring at any age and characterized by chronic inflammation, soft tissue proliferation and subsequent fibrosis of various vascular connective tissues. Following diagnosis in a 43-year accountant with multiple vascular lesions, the patients was treated successfully with azathioprine and steroids over a period of 3 years. Fatigue and sweating, serologic ...

Joint deformity secondary to extensive haemangiomatous involvement of the soft tissues has been well described and is easy to diagnose. If the haemangioma is small, localised and within the belly of a muscle the diagnosis is more difficult. In equinus deformity of obscure aetiology localised calf tenderness may be the only diagnostic sign. Three children with equinus deformity caused by a small...

Frequency-dependent third and fourth moments of the Barkhausen signal from a soft amorphous ferromagnet are measured. The data indicate strong coupling between the power in different frequency bands. The sign of the time asymmetry of a third-order voltage correlation indicates that the high-frequency Barkhausen events, on average, systematically precede the low-frequency Barkhausen events. The ...

in this work, we define fuzzy soft ($fs$) matrices and theiroperations which are more functional to make theoretical studies inthe $fs$-set theory. we then define products of $fs$-matrices andstudy their properties. we finally construct a $fs$-$max$-$min$decision making method which can be successfully applied to theproblems that contain uncertainties.
