x being the unknown. Assume that, given an instance (A, b), we wish to solve it to a given accuracy E on the basis of “matrix-vector mu ltiplications.” More precisely, assume that we are given b… (More)

We recently revealed a unique glycan on the Fc domain of IgG antibodies in ALS patients that mediates antibody-dependent cell cytotoxicity (ADCC). This glycan has a bi-antennary structure that lacks… (More)

Assume that, solving a problem (A, b), we are given the vector b beforehand and at each step can multiply any vector from H on our choice by A; this is the only information available during the… (More)
