We describe the deformed Poincare-conformal symmetries implying the covariance of the noncommutative space obeying Snyder’s algebra. Relativistic particle models invariant under these deformed symmetries are presented. A gauge (reparametrisation) independent derivation of Snyder’s algebra from such models is given. The algebraic transformations relating the deformed symmetries with the usual (u...

The dust ball collapse is studied in the context of "rainbow metric" approach (where matter content supplemented with a scalar field perturbation) to Oppenheimer-Snyder scenario within framework loop quantum cosmology. global spacetime structure determined for this and subsequently used evaluate entanglement entropy via slight adaptation existing formulas. resulting model shown qualitatively re...

Objective: Dysfunctional beliefs of tuberculosis patients have pivotal role in treatment and development of their serious psychiatric problems. Cognitive group psychotherapy has been utilized to manage the dysfunctional beliefs. Methods: In a quasi-experimental study and a pretest and posttest design, 24 male tubercular patients were selected by convenient sampling and then randomly assigned...
