â â â â â â â â â â â  â  abstract â  the foreign exchange market (fx market) accounts for 40% of the total volume of the world’s e-commerce by its own. based on statistics, sometimes up to 90 per cent of the traders lose their total capital in this market just within six months to one year and leave this market. the probability of loss in the fx market can be estimated by probability theory....

In this article we consider three versions of the spreading activation model for retrieval of information from memory. Predictions are derived for activation spreading down a linear network structure as a function of time. To test these predictions, two experiments were performed in which facilitation as a function of time was measured for target words in a linearly structured paragraph. A targ...

The recognition of needle entry into an epidural space is a pivotal moment in cervical, thoracic, or lumbar epidural injections. Its significance cannot be overestimated. Regardless of how experienced you are, realizing that you are approaching an epidural space makes your heart beat faster. The safety of the procedure and its success rate depends upon proper and reliable identification of the ...

Translation planes of order q and kernel containing KGGFðqÞ admitting fixedpoint-free collineation groups GK , each of whose point orbits is the set of nonzero vectors of a 2-dimensional K-subspace, are shown to permit spread-retraction and produce either Baer subgeometry or mixed partitions of a corresponding projective space. When the same translation plane or spread produces a number of part...

JCB • VOLUME 180 • NUMBER 3 • 2008 446 DNA spring in your spindle D NA is a mechanical piece of the spindle, if results from Elaine Yeh, Kerry Bloom, and colleagues (University of North Carolina, Chapel Hill, NC) are any indication. The inherent springiness of DNA may be part of the spindle’s tension-sensing mechanism. During mitosis, tension between chromosomes indicates that each of two siste...

Plasmodesmata (PDs) are microscopic channels that connect virtually every plant cell to its neighbors. They also provide a route for molecules to access the phloem for systemic movement throughout the plant. In this report, I review recent findings that broaden the potential impact of these channels, by revealing their contribution to auxin movement and as potential sites of receptor signaling....

This paper is concerned with a dynamic trading strategy, which involves multiple synthetic spreads each of which involves long positions in a basket of underlying securities and short positions in another basket. We assume that the spreads can be modeled as mean-reverting Ornstein-Uhlenbeck (OU) processes. The dynamic trading strategy is implemented as the solution to a stochastic optimal contr...

How does information behave? A recent controversial approach is to use ideas in evolutionary biology to study the spread of information. However, in order for the information to ‘evolve’, there has to be some mechanism for variation. This paper would explore the ideas of memes which use the evolutionary biology approach as well as the pitfalls in using this picture. Finally, we will focus our a...
