Self-amplified spontaneous emission in a free-electron laser has been proposed for the
generation of very high brightness coherent x-rays. This process involves passing a high-energy…

This study reviews 21 microvascular free flaps to the diabetic foot in 19 patients over a 65-month
period. All flaps were either to the plantar surface of the foot or to cover exposed …

… a band matrix t7 the solution of the system/~x = y may be computed at the cost O(N) arithmetic
… In the case of well posed boundary conditions the output y is uniquely determAned by the …

… It is useful to note that [x] = [y] if and only if x − y e E1. Now we introduce a linear structure
on … For two points x and y we introduce the set {Ax+(1-A)y) for 0 < A s 1, which is the line …

… The product y = Ax of the matrix A by the vector x is a vector y = col(y(i))N i=1 with column
coordinates y(i) of sizes mi. We consider various procedures to compute the components y(i). …

A high precision measurement of the Ψ- and Ψ′-resonance masses has been performed at
the new storage ring VEPP-4. The resonance depolarization method has been used for the …

The MARS15(2012) is the latest version of a multi-purpose Monte-Carlo code developed
since 1974 for detailed simulation of hadronic and electromagnetic cascades in an arbitrary 3-…

We study a class of block structured matrices R={R ij } i,j=1 N with a property that the solution
of the corresponding system Rx=y of linear algebraic equations may be performed for O(N) …
