A 45-year-old woman presented to the emergency department with left wrist pain following a fall. Physical exam was remarkable for soft tissue swelling of the palmar and dorsal hand, point tenderness at the base of the second metacarpal, and limited active range of motion. Three-view wrist radiographs showed significant soft tissue swelling without evidence of fracture or dislocation. Computed t...

In this paper, we provide several bounds for the modulus of complex Čebyšev functional. Applications to trapezoid and mid-point inequalities, that are symmetric also provided.

A new generalization of weighted companion for the Ostrowski and the generalized trapezoid inequalities for mappings of bounded variation are established.

We present a 5-year follow-up of a patient with bilateral necrosis of the trapezoid that improved clinically and radiographically with nonoperative treatment.

A generalized trapezoid rule is derived. Various error bounds for this rule are established. © 2005 Elsevier Ltd. All rights reserved. MSC: 26D15; 65D30

Tolerance graphs model interval relations in such a way that intervals can tolerate a certain degree of overlap without being in conflict. This subclass of perfect graphs has been extensively studied, due to both its interesting structure and its numerous applications. Several efficient algorithms for optimization problems that are NP-hard on general graphs have been designed for tolerance grap...
