    A function f(x)from the finite field GF(pn)to itself is said to be differentially δ-uniform when the maximum number of solutions x ∈GF(pn)of f(x +a) −f(x) =bfor any a ∈GF(pn)∗and b ∈GF(pn)is equal to δ. Let p =3and d =3n−3. ...

Ellen; Astle, William J.; Watkins, Nicholas A.; Lane, William J. (Journal article; Peer reviewed, 2020)
    Each year, blood transfusions save millions of lives. However, under current blood-matching practices, sensitization to non–self-antigens is an unavoidable adverse side effect of transfusion. We describe a universal donor ...
  • Approximation in (poly-) logarithmic space 

    Biswas, Arindam; Raman, Venkatesh; Saurabh, Saket (Journal article; Peer reviewed, 2020)
