A personal selection is made of some of the hot topics debated at this conference, including examples of using our knowledge of QCD to make electroweak measurements, structure functions at low x in the light of the corrections to the leading BFKL behaviour recently calculated, diffraction, the existence of one or more Pomerons and whether it/they may have a well-defined structure function, some...
We introduce intermediation frictions into a Lucas (1978) asset pricing model in order to study the effects of low capital in the intermediary sector on asset prices. Our model shows that low intermediary capital can increase risk premia, Sharpe ratios, volatility and comovement among intermediated assets. Reductions in intermediary capital also lead to a flight-to-quality in which intermediari...
BACKGROUND Transverse nasal crease is an uncommonly reported entity. It likely represents an embryologic fault line. Transverse nasal milia have also been reported in the same location, both as an isolated finding and in a transverse nasal crease. This observation suggests they are variants of the same entity. OBSERVATIONS Two cases, one of transverse nasal crease with milia and one of transv...
During the development of peripheral nerves, pioneer axons often navigate over mesodermal tissues. In this paper, we examine the role of the mesodermal cell determination gene tinman on cells that provide pathfinding cues in Drosophila. We focus on a subset of peripheral nerves, the transverse nerves, that innervate abdominal segments. During wildtype embryonic development, the transverse nerve...
Mechanisms proposed to explain the jet-related correlation of long range in rapidity (the ridge) observed in high-energy heavy-ion collisions are reviewed. Limitations of a model using the combined effect of transverse flow and a direction bias of partons suffering energy loss are discussed. The influence of the time scale of the correlation mechanism on the rapidity range is investigated.
We calculate the self-energy of two-dimensional fermions that are coupled to transverse gauge fields, taking two-loop corrections into account. Given a bare gauge field propagator that diverges for small momentum transfers q as 1/q , 1 < η ≤ 2, the fermionic self-energy without vertex corrections vanishes for small frequencies ω as Σ(ω) ∝ ω with γ = 2 1+η < 1. We show that inclusion of the lead...

We give a combinatorial treatment of transverse homology, a new invariant of transverse knots that is an extension of knot contact homology. The theory comes in several flavors, including one that is an invariant of topological knots and produces a three-variable knot polynomial related to the A-polynomial. We provide a number of computations of transverse homology that demonstrate its effectiv...
The typical transverse momentum of a quark in the proton is basic property any QCD based model nucleon structure. However, calculations phenomenological models typically give rather small values momenta, which are difficult to reconcile with larger observed high energy experiments such as Drell-Yan reactions and Semi-inclusive deep inelastic scattering. In this letter we calculate leading twist...
