    SWI/SNF chromatin remodeling complex is required for initiation of sex-dependent differentiation in mouse germline

    Sexual reproduction involves the creation of sex-dependent gametes, oocytes and sperm. In mammals, sexually dimorphic differentiation commences in the primordial germ cells (PGCs) in embryonic gonads; PGCs in ...

    Ordinary p-adic étale Cohomology Groups Attached to Towers of Elliptic Modular Curves

    Fix a prime number p ≥ 5 and a positive integer N prime to p. We consider the projective limits of p-adic étale cohomology groups of the modular curves X1(Npr) and Y1(Npr) (r ≥ 1), which are denoted by ESp(N) Z p
