Numerical Solution of Fuzzy Arbitrary Order Predator-Prey Equations

This paper seeks to investigate the numerical solution of fuzzy arbitrary order predator-prey equations using the Homotopy Perturbation Method (HPM). Fuzziness in the initial conditions is taken to mean convex normalised fuzzy sets viz. triangular fuzzy number. Comparisons are made between crisp solution given by others and fuzzy solution in special cases. The results obtained are depicted in plots and tables to demonstrate the efficacy and powerfulness of the methodology

Childhood Pseudoxanthomatousmastocytosis; Report of two cases

Cutaneous mastocytosis (CM) is a mast cell proliferative disorder that commonly affects pediatric population. It has various clinical forms such as urticaria pigmentosa, solitary mastocytoma, telangiectasia macularis eruptiva perstans, diffuse CM, and erythrodermic mastocytosis. Pseudoxanthomatous mastocytosis is a type of diffuse CM, which is relatively rare. It can mimic xanthoma disseminatum, juvenile xanthogranuloma, and benign cephalic histiocytosis which are also seen commonly in children but have different prognostic behavior. Hence, high degree of clinical suspicion along with histopathology is required for the diagnosis. Herein, we report two cases of childhood pseudoxanthomatous mastocytosis
