A plain radiograph showed discrete areas of calcification around the cuboid and bases of his 4th and 5th metatarsals, with scalloping of the cuboid in keeping with a long standing pressure effect (fig. 1); these features were reported as being consistent with synovial chondromatosis. Magnetic resonance imaging (MRI) confirmed the diagnosis by revealing multiple foci of low signal intensity surr...

We report eight cases of fracture of the cuboid in seven children under four years of age, collected during a two-year period. There was no history of trauma in five of the patients. This fracture is rarely diagnosed and has probably been under-reported. Small children are poor historians and difficult to examine, and early radiographs may be normal or have only subtle abnormalities. Cuboid fra...

Spatial perspective-taking is an ability to understand in which direction an object is located relative to an agent (e.g., another person or a chair). Previous studies showed that left/right judgments prompted an egocentric transformation strategy (i.e., mental rotation of the self) whereas front/behind judgments prompted other strategies (e.g., tracing a line of sight). To examine whether the ...

The Lambrinudi arthrodesis for drop foot is a popular operation not only because it yields good results but also because fusion occurs more easily than in other methods. The Lambrinudi operation is usually indicated in the correction of talipes equinus or equinovarus. The chief features of the operation are : excision of a wedge of bone from the talus and calcaneum, including the subtalar joint...

  This report presents a 3.5-year-old boy who was hospitalized for limping. Medical history and physical exams were not suggestive for any definitive diagnosis. Laboratory and radiographic exams did not support any specific diagnosis either. Subsequently bone scan was performed and increased activity in the ankle due to cuboid fracture was incidentally observed.

We describe a method for reconstructing indoor scenes from image mosaics using prior knowledge of the cuboid structure of the environment. The method is inspired by traditional approaches to the camera pose estimation problems known as the PnL and PnA problems. We show that a cuboid can be reconstructed from the images of three of its corners. The necessary camera intrinsic parameters are obtai...

A 3D T-mesh is basically a partition of a cuboid such that every part is a smaller cuboid. In this paper we define the spline spaces over 3D T-meshes, which would play an important role in adaptive and dynamic implicit surface reconstruction from unorganized point clouds, and present a dimension formula about the spline space over a special kind of T-mesh, i.e., 3D hierarchical T-mesh. The form...

The level-spacing distribution of consecutive energy eigenvalues is calculated numerically at the metal insulator transition for 3d systems with different cuboid shapes. It is found that the scale independent critical P c (s) changes as a function of the aspect ratio of the samples while the critical disorder W c /V = 16.4 remains the same. We use our data to test whether an expression for the ...

Three-dimensional information of the burden surface in high temperature and excessive dust industrial conditions has been previously hard to obtain. This paper presents a novel microstrip-fed dielectric-filled waveguide antenna element which is resistant to dust and high temperatures. A novel microstrip-to-dielectric-loaded waveguide transition was developed. A cylinder and cuboid composite str...

Particle shape was one of the most important factors which affects the gravel aggregate’s properties. It was also one of the important factors that directly affects the performance of asphalt pavements. In this paper, the gravel aggregate of quartzite was studied by using the industrial CT instrument. MATLAB was used to capture the aggregate slice properties including reverse color, median filt...
