The histone chaperone FACT is an essential and abundant heterodimer found in all eukaryotes. Here we report a crystal structure of the middle domain of the large subunit of FACT (Spt16-M) to reveal a double pleckstrin homology architecture. This structure was found previously in the Pob3-M domain of the small subunit of FACT and in the related histone chaperone Rtt106, although Spt16-M is disti...

In this paper we characterize the radical of an arbitrary‎ ‎submodule $N$ of a finitely generated free module $F$ over a‎ ‎commutatitve ring $R$ with identity‎. ‎Also we study submodules of‎ ‎$F$ which satisfy the radical formula‎. ‎Finally we derive‎ ‎necessary and sufficient conditions for $R$ to be a‎ ‎Pr$ddot{mbox{u}}$fer domain‎, ‎in terms of the radical of a‎ ‎cyclic submodule in $Rbigopl...

We prove existence of global weak L solutions of the inviscid SQG equation in bounded domains.

We construct an abundance of Hilbertian domains: Let O be a countable separably Hilbertian domain with a qoutient eld K and let e 2 be an integer. Let L be an abelian extension of K such that ford(a) j a 2 G(L=K)g is unbounded, and let O L be the integral closure of O in L. Then, for almost all 2 G(K) e , each ring between O L and L K s () is separably Hilbertian.

In this paper, we consider Hankel operators on domains with bounded intrinsic geometry. For these characterize the $$L^2$$ -symbols where associated operator is compact (respectively bounded) space of square integrable holomorphic functions.

We study the Bergman kernel and projection on the worm domains Dβ = { ζ ∈ C : Re ( ζ1e −i log |ζ2| 2) > 0, ∣∣ log |ζ2| ∣∣ < β − π 2 } and D β = { z ∈ C : ∣Im z1 − log |z2| ∣∣ < π 2 , | log |z2| | < β − π 2 } for β > π. These two domains are biholomorphically equivalent via the mapping D β ∋ (z1, z2) 7→ (e z1 , z2) ∋ Dβ . We calculate the kernels explicitly, up to an error term that can be contr...
