A comment on pulsatile pipe flow
This article is concerned with analytic solutions of flows in cylindrical and annular pipes subject to an arbitrary time dependent pressure gradient and arbitrary initial flow
Independent Sector Regulators and their Relationship with Competition Authorities
Independent sector regulators and competition authorities share many objectives and common interests, particularly because they both can play key roles in promoting effective and beneficial competition. In this note, the criteria and rationale for the independence of sector regulators and competition authorities are explained, along with a suggestion that independence may sometimes be especially critical for institutions with broad economic oversight and quasi-judicial responsibilities or, alternately, for institutions most subject to influence of special interests. The note suggests that sector regulators may benefit, in times of high technological change and uncertainty, from principle-based laws that allow regulators the flexibility to adjust their precise rules in light of evolving circumstances. Moreover, the note suggests that in some respects, the sectors subject to independent regulation may usefully include other sectors beyond those most traditionally associated with independent regulation. Ultimately, ensuring consistency and convergence between sector regulator and competition authority objectives and actions is important; ironically, independence can make ensuring such consistency through direct co-operation a challenge. Based on international experience, multiple mechanisms exist for achieving or encouraging such consistency; some combination of these merits consideration by designers of competition policy regimes
Soft Collinear Effective Theory
In this talk I review soft collinear effective theory. After a discussion of
the formalism and properties of the effective field theory, I turn to
phenomenology. I present results on color-suppressed B to D decays, and on the
Upsilon radiative decay spectrum.Comment: 6 Pages, 3 figures. Parallel session overview talk presented at

Widening the Nexus: From T-R to T-T-R
Higher education institutions are operating with scarce resources in a complex environment, and subject to various, often competing or changing demands. The integration of teaching, research and third stream activities within a coherent academic framework provides an opportunity to manage and exploit the positive relationships between these activities. This approach may also help to ease some of the tensions and 'fault lines' that currently beset academic life
