The two-mass contribution to the three-loop pure singlet operator matrix element [PDF]
, 2017 We present the two-mass QCD contributions to the pure singlet operator matrix element at three loop order in x-space. These terms are relevant for calculating the structure function $F_2(x,Q^2)$ at $O(\alpha_s^3)$ as well as for the matching relations in

Growth of β-LiNaSO4 and Li2SO4 . H20: epitaxy and intergrowth phenomena [PDF]
, 1995 Isothermal crystallization in the system Na2SO4-Li2SO4-H20 was carried out at 50°C by "salting out" in a tetrametoxysilane (TMS) gel medium. Under these conditions the solid phases that can crystallize are Na2SO4, Li2SO4 . H20 and β-LiNaSO4, depending on

Invariant subspaces with no generator and a problem of H. Helson [PDF]
, 2015 In the almost periodic context, any $H_0^2-$space cannot be generated by one of its elements. Together with cocycle argument, this derives that there exist all kinds of invariant subspaces without single generator, from which we can answer some questions

Advanced Healthcare Materials, EarlyView.Commercial vascular grafts are made from ePTFE, a highly hydrophobic, foreign material that fails at a high rate in small‐diameter applications. Plasma polymer nanoparticles (PPN) are a versatile material functionalisation tool, used here to present fibrillin‐1 fragment PF8 on the graft surface.

Advanced Healthcare Materials, EarlyView.Polymer‐based drug delivery systems can effectively overcome the limitations of free drugs in terms of solubility, stability, and plasma half‐life, yet their development has traditionally relied on time‐consuming trial‐and‐error approaches. This review highlights recent advances in applying molecular simulation to the design of polymer‐based drug ...
