Fungus is one of the causes of chronic rhinosinusitis. If the fungus occupies the sinus but does not invade the sinonasal mucosa, this is called sinus fungus ball. Any association between anatomical variations and fungus ball remains unclear. Sinus fungus ball is defined as non-invasive chronic fungal rhinosinusitis occurring in immunocompetent patients, and the maxillary sinus is the most comm...

Newly hatched chicks will spontaneously peck at conspicuous objects in their field of view, and soon learn to distinguish between edible food particles and unpleasant tasting objects. To examine whether the selective pecking is based on the ability to memorize shapes, we analyzed pecking behavior of 1- to 2-days-old quail chicks (Coturnix japonica) by using ball- and triangle-shaped beads both ...

Three experiments were conducted to examine the mediating process involved in the low-ball procedure for increasing compliance. In Experiment 1, subjects who agreed to but were not allowed to perform an initial request complied with a more costly version of the same request to a greater extent than did controls only when the second request came from the same person as did the first request and ...

Due to the growth of media services in football broadcasting, a Swedish company called TRACAB is modelling the reconstruction of football matches in 3-D. TRACAB has developed a system to track players’ positions for the whole match using cameras installed in each stadium. However, this system is less reliable when applied to tracking the football. Therefore this Master Thesis focuses on estimat...

In this paper we present ongoing work on how to incorporate human motion models into the design of a high performance teleoperation platform. A short description of human motion models used for ball-catching is followed by a more detailed study of a teleoperation platform on which to conduct experiments. Also, a pilot study using minimum jerk theory to explain user input behavior in teleoperate...

A refined form of the ‘Folk Theorem’ that a smooth action by a compact Lie group can be (canonically) resolved, by iterated blow up, to have unique isotropy type is proved in the context of manifolds with corners. This procedure is shown to capture the simultaneous resolution of all isotropy types in a ‘resolution structure’ consisting of equivariant iterated fibrations of the boundary faces. T...

Let f ∈ Lloc(R) ∩ S ′, S ′ is the Schwartz class of distributions, and ∫ σ(D) f(x)dx = 0 ∀σ ∈ G, (∗) whereD ⊂ Rn, n ≥ 2, is a bounded domain, the closure D̄ of which is C1−diffeomorphic to a closed ball. Then the complement of D̄ is connected and path connected. Here G denotes the group of all rigid motions in Rn. This group consists of all translations and rotations. It is conjectured that if f ...

Because of the hairy ball theorem, the only closed 2-manifold that supports a lattice in its tangent space is T . But, if singular points (i.e. points whose tangent space is not endowed with 2 distinct coordinate directions) are allowed, then it becomes possible to give the tangent space a lattice. Because the lattice is well defined everywhere around the points, the effect of moving around the...

Denote by B the n-dimensional unit ball centred at o. It is known that in every lattice packing of B there is a cylindrical hole of infinite length whenever n ≥ 3. As a counterpart, this note mainly proves the following result: For any fixed , > 0, there exist a periodic point set P (n, ) and a constant c(n, ) such that B + P (n, ) is a packing in R, and the length of the longest segment contai...
