Automatic detection of anatomical features on 3D ear impressions for canonical representation.

We propose a shape descriptor for 3D ear impressions, derived from a comprehensive set of anatomical features. Motivated by hearing aid (HA) manufacturing, the selection of the anatomical features is carried out according to their uniqueness and importance in HA design. This leads to a canonical ear signature that is highly distinctive and potentially well suited for classification.

Layout consistent segmentation of 3-D meshes via conditional random fields and spatial ordering constraints.

We address the problem of 3-D Mesh segmentation for categories of objects with known part structure. Part labels are derived from a semantic interpretation of non-overlapping subsurfaces. Our approach models the label distribution using a Conditional Random Field (CRF) that imposes constraints on the relative spatial arrangement of neighboring labels, thereby ensuring semantic consistency.

Motor and electrocorticographic epileptic activity induced by 3-mercaptopropionic acid in immature rats.

The convulsant action of 3-mercaptopropionic acid (3-MPA), a known inhibitor of glutamate decarboxylase activity, was studied in 7-, 12-, 18- and 25-day-old rats and in adult animals. 3-MPA elicited predominantly clonic, minimal seizures as well as generalized tonic-clonic (major) seizures at all developmental stages studied. The CD50 for major seizures did not change during development; CD50 for minimal seizures was significantly lower in 18-day-old rats than in older animals.

[Differential diagnosis in early muscular hypotonia: spinal atrophy].

Changes in type, size and structure of muscle fibres were analyzed in 68 biopsies with clinical and morphological signs of spinal atrophy. Reliability of clinical prebioptic diagnosis was evaluated in comparison with bioptic finding and final diagnosis. Muscle biopsy is often to be performed in spite of apparently unambiguous clinical and electromyographical finding.

[Computer tomography in the diagnosis of neuromuscular diseases in children].

Recently in the literature occasional reports were published on the use of computed tomography (CT) in the diagnosis of neuromuscular diseases. The authors compared in a group of 23 children aged 3 to 15 years the results of clinical, laboratory, electromyographic, bioptic and CT findings on muscles. Only in four children the result of CT did not correlate with the clinical finding because of the incipient stage of the disease with structural changes which were yet only slightly expressed.
