calcifying fibrous tumor (cft) is a rare mesenchymal tumor, affecting children and young adults with a predilection for the soft tissue and the abdominal cavity. cft of the tubular gastrointestinal tract is very rare with less than 20 cases of gastric cfts reported in english literature. this benign hypocellular fibrosclerotic calcifying lesion can resemble other spindle cell tumors particularl...

It has been conjectured that the (weakly coupled) Randall-Sundrum (RS) model with gauge fields in the bulk is dual to a (strongly coupled) 4D conformal field theory (CFT) with an UV cut-off and in which global symmetries of the CFT are gauged. We elucidate features of this dual CFT which are crucial for a complete understanding of the proposed duality. We argue that the limit of no (or small) b...

The number of asymptotically de Sitter (non-singular) solutions of 5d dilatonic gravity with positive cosmological constant is found. These solutions are similar to the previously known asymptotically AdS spaces where dilaton may generate the singularity. Using these solutions the consistent c-function is proposed in the same way as in AdS/CFT. The consistency of RG flow gives further support f...

The Yale art historian George Hersey showed us the columns in Figure 1 and asked us whether the ideas of symmetry breaking could be used to help classify architectural columns. Provoked by this question and the intriguing columns in that figure, we attempted to answer Hersey in the following way. We view a column as a deformed cylinder and column symmetries as the subgroup of the symmetries of ...

Recently several generalizations to higher dimension of the classical Fourier transform (FT) using Clifford geometric algebra have been introduced, including the two-dimensional (2D) Clifford Fourier transform (CFT). Based on the 2D CFT, we establish the two-dimensional Clifford windowed Fourier transform (CWFT). Using the spectral representation of the CFT, we derive several important properti...

In the context of the AdS/CFT correspondence it is well-known that correlation functions of local operators in the CFT are dual to boundary correlators computed in anti-de Sitter space. But from the point of view of AdS supergravity one of the most interesting questions is how quasi-local bulk gravitational physics emerges from the CFT. The most direct way to address this question is to study c...

We have shown previously that inhalation anaesthetics inhibit dopamine transport in rat synaptosomes. In order to determine if this inhibition is associated with occupancy of the cocaine site, we examined binding of [3H] (2 beta-carbomethoxy-3 beta-(4-fluorophenyl)-tropane) (3H-CFT) in the presence of halothane or isoflurane 0.01-5 mmol litre-1 in rat brain synaptosomes. Both anaesthetics inhib...
