Volume of trades and order book volume imbalances have long been established as important criteria in evaluating portfolios and long term investment strategies. The hypothesis being evaluated in this project is that it is an essential component of intraday trading strategies – important enough to be effectively used exclusively as an indicator of the market behavior. The design of a trading str...

Finite type invariants of knots or links can be defined combinatorially using only link projections in S. In this setting it can be seen that every Jones-type polynomial invariant (quantum invariants) is equivalent to a sequence of finite type invariants. See [B2, BN] and references therein. Although Vassiliev’s original approach to finite type knot invariants ([V]) rests on topological foundat...

The tool described in this paper aims at evaluating the effectiveness of software-implemented faulttolerant techniques used in safety-critical systems. The target application is stressed with the injection of transient or permanent faults. The user can therefore observe the real behaviour of the application in presence of a fault, and, if necessary, take the appropriate countermeasures. The acc...

We give a new definition of the knot invariant associated to the Lie algebra suNC1 . Knowing these for all N is equivalent to knowing the HOMFLY polynomial. Our definition requires that the knot or link be presented as the plat closure of a braid. The invariant is then a homological intersection pairing between two immersed manifolds in a configuration space of points in a disk. This generalize...

Südhof TC: α α-Latrotoxin receptor CIRL/latrophilin 1 (CL1) defines an unusual family of ubiquitous G-protein-linked receptors. requirements for α α-latrotoxin binding and α α-latrotoxin-stimulated secretion. α α-Latrotoxin stimulates exocytosis by the interaction with a neuronal G-protein-coupled receptor. AG: A novel ubiquitously expressed α α-latrotoxin receptor is a member of the CIRL famil...

In this paper we present a mechanism for determining nearoptimal prices for tasks in online labor markets, often used for crowdsourcing. In particular, the mechanisms are designed to handle the intricacies of markets like Mechanical Turk where workers arrive online and requesters have budget constraints. The mechanism is incentive compatible, budget feasible, and has competitive ratio performan...
