TL;DR: In this paper, a 3D finite difference time domain model is used to simulate the lightning electromagnetic pulse (EMP) and its interaction with the lower ionosphere, showing that the structure exhibits asymmetry due to the presence of Earth's ambient magnetic field.
Abstract: [1] A 3-D finite difference time domain model is used to simulate the lightning electromagnetic pulse (EMP) and its interaction with the lower ionosphere. Results agree with the frequently observed, doughnut-shaped optical signature of elves but show that the structure exhibits asymmetry due to the presence of Earth's ambient magnetic field. Furthermore, in-cloud (horizontal) lightning channels produce observable optical emissions without the doughnut shape and, in fact, produce a much stronger optical output for the same channel current. Electron density perturbations associated with elves are also calculated, with contributions from attachment and ionization. Results presented as a function of parameters such as magnetic field direction, dipole current orientation, altitude and amplitude, and ambient ionospheric density profile demonstrate the highly nonlinear nature of the EMP-ionosphere interaction. Ionospheric effects of a sequence of in-cloud discharges are calculated, simulating a burst of in-cloud lightning activity and resulting in large density changes in the overlying ionosphere.

10 Jun 2010TL;DR: In this paper, an electronic trading marketplace (ETM) communicates with interfacing modules interfacing directly with order management systems (OMS's) at trading institutions, which automatically transmit orders from the OMS databases to the ETM and update the order management system in response to orders executed at the EMT.
Abstract: An electronic trading marketplace (ETM) communicates with interfacing modules interfacing directly with order management systems (OMS's) at trading institutions. The interfacing modules automatically transmit orders from the OMS databases to the ETM and update the OMS databases in response to orders executed at the ETM. Traders can communicate with the ETM to anonymously negotiate trades of securities.

28 Oct 2011TL;DR: In this paper, the authors present a computer implemented trade execution method, comprising: sending from an execution venue to each of a plurality of smart order routers a notification message; receiving at each of the smart order router the notification message sent to the execution venue, wherein the message notifies each smart order receiver about the presence of a non-displayed priced order.
Abstract: One embodiment of the present invention relates to securities trading using electronic systems. Another embodiment of the present invention relates to a computer implemented trade execution method, comprising: sending from an execution venue to each of a plurality of smart order routers a notification message; receiving at each of the smart order routers the notification message sent thereto, wherein the notification message notifies each of the smart order routers about the presence of a non-displayed priced order at the execution venue; sending from at least one of the smart order routers to the execution venue at least one order to execute against the non-displayed priced order; receiving at the execution venue each order sent from each of the smart order routers; and executing at least one order received from at least one of the smart order routers against the non-displayed priced order.
