Covariant four dimensional differential calculus in κ-Minkowski

It is generally believed that it is not possible to have a four dimensional differential calculus in κ-Minkowski spacetime, with κ-Poincaré relativistic symmetries, covariant under (κ-deformed) Lorentz transformations.Thus, one usually introduces a fifth differential form, whose physical interpretation is still challenging, and defines berness

Coracoid Abnormalities and Their Relationship with Glenohumeral Deformities in Children with Obstetric Brachial Plexus Injury

Abstract Background Patients with incomplete recovery from obstetric brachial plexus injury (OBPI) usually develop secondary muscle imbalances and bone deformities at the shoulder joint.Considerable efforts have been made read more to characterize and correct the glenohumeral deformities, and relatively less emphasis has been placed on the more sub
