Open AccessC-reactive protein levels, the prognostic nutritional index, and the lactate dehydrogenase-to-lymphocyte ratio are important prognostic factors in primary central nervous system lymphoma: a single-center study of 223 patients
Primary central nervous system lymphoma (PCNSL) is a rare and highly aggressive type of extranodal non-Hodgkin lymphoma (NHL), and the prognosis is poor. Currently, the most used prognostic models are the Memo...

Solution methodologies for minimizing a sum of pointwise minima of two functions
In this paper, an NP-hard problem of minimizing a sum of pointwise minima of two functions is considered. Using a new equivalent formula, we propose a smooth approximation and an ADMM algorithm for solving the...
