background: the classical supportive therapy for î² -thalassemia major consists of regular blood transfusion, iron-chelation therapy and specific treatment of the related complications. a balance between the maintenance of the highest possible level of haemoglobin and lowest possible level of iron accumulation in heart and liver give the best chance of survival and the best quality of life. met...

We show that some singular maximal functions and singular Radon transforms satisfy a weak type L log logL inequality. Examples include the maximal function and Hilbert transform associated to averages along a parabola. The weak type inequality yields pointwise convergence results for functions which are locally in L log logL. 1.Introduction Let Σ be a compact smooth hypersurface of R, and let μ...

Abstract In order to study integral points of bounded log-anticanonical height on weak del Pezzo surfaces, we classify pairs. As a representative example, consider quartic surface singularity type $\mathbf {A}_1+\mathbf {A}_3$ and prove an analogue Manin’s conjecture for with respect its singularities lines.
