verbal broadsides. Two chapters are devoted to differential diagnosis. rhe wvork is based on the author's experience of 1,000 operations for lumbar disc lesions, but he omits to state how nany cases this represents altogether. However, he mentions that operation is carried out in somewhere between 10 and 20 per cent of cases, so that he must have seen a veiy large rnulmber o,f patients with low...

Retrieving photography ideas corresponding to a given location facilitates the usage of smart cameras, where there is a high interest among amateurs and enthusiasts to take astonishing photos at anytime and in any location. Existing research captures some aesthetic techniques and retrieves useful feedbacks based on one technique. However, they are restricted to a particular technique and the re...

This paper presents a convenient graphical tool for encoding visual patterns (such as image patches and image atoms) as point constellations in a space spanned by perceptual features and with a clear geometrical interpretation. General theory and a practical pattern encoding scheme are presented, inspired by encoding polarization states of a light wave on the Poincaré sphere. This new pattern e...

Anders Björner characterized which finite graded partially ordered sets arise as the closure relation on cells of a finite regular CW complex. His characterization of these “CW posets” required each open interval (0̂, u) to have order complex homeomorphic to a sphere of dimension rk(u)− 2. Work of Danaraj and Klee showed that sufficient conditions were for the poset to be thin and shellable. The...

In the pattern matching approach to imaging science, the process of “metamorphosis” is template matching with dynamical templates (Trouvé and Younes, Found. Comp. Math., 2005). Here, we recast the metamorphosis equations of that paper into the Euler-Poincaré variational framework of Holm, Marsden, and Ratiu, Adv. in Math., 1998 and show that the metamorphosis equations contain the equations for...

Existence of periodic solutions for non-linear third order autonomous differential equation (O.D.E.) has not been investigated to as large an extent as non-linear second order. The popular Poincare-Bendixon theorem applicable to second order equation is not valid for third order equation (see [3]). This conclusion opens a way for further investigation.

As to the relationship between extraverted disposition and preference for social communication on Internet community, there have been two hypotheses: “Social Enhancement” (“Rich Get Richer”) and “Social Compensation” (“Poor Get Richer”). In this paper, we examined the role of using real-life portrait as facial picture in determining whether an extraverted user would be sociable on Internet comm...
