conclusion dt-sfp can improve the detection of relatively early bone abnormalities in acetabular and proximal femur compared with conventional radiography. dt-sfp can also observe the abnormal impact between acetabular and proximal femur. patients and methods ninety-four consecutive patients with discomfort around the hip joint underwent dt-sfp and conventional radiography. the imaging features...

to find if some indices have predictive value for renal complications. we conducted a cross sectional and included 80 patients with the age ranged 5-17 years, all with the proven diagnosis of β-thalassemia major. a urine and 5 ml of blood sample were obtained from all of the cases. biochemical indices such as serum levels of creatinine, na, mg, hb, and ferritin and also urine levels of na, mg, ...

the distally based sural fasciocutaneous flap has become a main part of the reconstruction of the lower leg, heel and foot. however, perfusion problems and venous congestion have been reported. over the past decade, several flap modifications have been reported to improve flap viability and to solve a myriad of reconstructive needs. the purpose of this paper is to describe our experience in har...

We consider the problem of minimizing a convex objective which is the sum of a smooth part, with Lipschitz continuous gradient, and a nonsmooth part. Inspired by various applications, we focus on the case when the nonsmooth part is a composition of a proper closed convex function P and a nonzero affine map, with the proximal mappings of τP , τ > 0, easy to compute. In this case, a direct applic...

Proximal and semi-proximal spaces are defined with the help of a game played on uniform spaces. Proximal spaces are where the entourage-picker has a winning strategy, and semi-proximal spaces are where the opponent, the point-picker, does not have a winning strategy. The class of proximal spaces is closed under Σ-products and closed subspaces. In this paper it is shown that product of two semi-...

‎In this paper‎, ‎we generalize the proximal point algorithm to complete CAT(0) spaces and show‎ ‎that the sequence generated by the proximal point algorithm‎ $w$-converges to a zero of the maximal‎ ‎monotone operator‎. ‎Also‎, ‎we prove that if $f‎: ‎Xrightarrow‎ ‎]-infty‎, +‎infty]$ is a proper‎, ‎convex and lower semicontinuous‎ ‎function on the complete CAT(0) space $X$‎, ‎then the proximal...
