temporal bone chondroblastoma is an extremely rare benign bone tumor. we encountered two cases showing similar imaging findings on computed tomography (ct), magnetic resonance imaging (mri), and dual-time-point 18f-fluorodeoxyglucose (18f-fdg) positron emission tomography (pet)/ct. in both cases, ct images revealed temporal bone defects and sclerotic changes around the tumor. most parts of the ...

Let £ be a closed, bounded, convex subset of a Banach space X, /: E —»E. Consider the iteration scheme defined by x"« = xQ e E, x , = ñx ), x = 2" na ,x., nal, where A is a regular weighted mean n + l ' n n * = 0 nk k o er matrix. For particular spaces X and functions /we show that this iterative scheme converges to a fixed point of /. Let X be a normed linear space, E a nonempty closed bounded...

We prove existence and uniqueness of global in time weak solutions for the Stokes system compressible fluids with a general, non-monotone pressure. construct solution at level Lagrangian formulation then define transformation to original Eulerian coordinates. For nonnegative bounded initial density, is all t>0 as well belongs L∞([0,∞)×Td). A key point our considerations such transformation. Sin...
