conclusions the use of variable-angle locking plates in treating unstable distal end radius fractures is associated with excellent to good functional outcomes with minimal complications. objectives this study aimed to evaluate the functional and radiological outcomes in unstable distal end radius fractures treated with variable-angle locking plates. patients and methods we reviewed 23 unstable ...

Let T and S be two bounded linear operators from Banach spaces X into Y and suppose that T is Fredholm and the stability number k(T ;S) is 0. Let d(T ;S) be the supremum of all r > 0 such that dimN(T − λS) and codim R(T − λS) are constant for all λ with |λ| < r. It was proved in 1980 by H. Bart and D.C. Lay that d(T ;S) = limn→∞ γn(T ;S) , where γn(T ;S) are some non-negative (extended) real nu...

background: there is inconsistent information about the role of psychological factors in the incidence of reflex sympathetic dystrophy (rsd) in patients with distal radius fractures. the present study was thus undertaken to evaluate the relationship between some of these factors and the occurrence of reflex sympathetic dystrophy in patients with distal radius fracture.   methods: one hundred an...

 We present an exceedingly rare case of left Monteggia-Galeazzi fracture-dislocation and right Monteggiadistal radius fracture occurring simultaneously in a 20-year old male patient who had fallen 13 meters from a building. The combination of Monteggia and Galeazzi fracture-dislocation in the same forearm is very rare and, to the best of our knowledge, simultaneous bilateral Monteggia and Galea...

in this paper, we study wsn design, as a multi-objective optimization problem using ga technique. we study the effects of ga parameters including population size, selection and crossover method and mutation probability on the design. choosing suitable parameters is a trade-off between different network criteria and characteristics. type of deployment, effect of network size, radio communication...

We show that binary microlensing events with three well-measured peaks (two caustic crossings plus a cusp approach) can yield determinations of both the projected Einstein radius r̃E and the angular Einstein radius θE, and so the lens mass M = c2(4G)−1r̃EθE. To a certain extent, rotation of the binary can mimic the effects of parallax, but should often be possible to disentangle parallax from rot...

We show that the joint spectral radius of a set of matrices is strictly increasing as a function of the data in the sense that if a set of matrices is contained in the relative interior of the convex hull of an irreducible set of matrices, then the joint spectral radius of the smaller set is strictly smaller than that of the larger set. This observation has some consequences in the theory of ti...

A precision aspheric artefact is measured in 3D by a commercially available nano-measuring machine (NMM) integrated with a contact inductive sensor as the probe. The mathematics of 3D compensation of the error caused by the probe radius is derived. The influence of the probe radius measurement uncertainty on the compensation errors for the 3D measurements is discussed. If the calibration uncert...
