In this work, we present a discrete time modeling framework, in which the shape and dynamics of a Limit Order Book (LOB) arise endogenously from an equilibrium between multiple market participants (agents). We use the proposed modeling framework to analyze the effects of trading frequency on market liquidity in a very general setting. In particular, we demonstrate the dual effect of high tradin...

There are many results on the possibilities of privacy leak in location-based services, and many remedies have also been suggested. In this paper, we look at this problem from an altogether different perspective claiming that privacy leaks are most likely inevitable for a lot of remedial mechanisms, and therefore it is necessary to provide means to a user to detect such leaks in advance. We spe...

This paper presents the results of using a novel Artificial Intelligence (AI) model for long-term investing. The AI model takes various financial data as input signals and tries to determine an optimal portfolio allocation. In these experiments, the AI model considers the stocks of 40 US companies, as well as the S&P 500 index and US government bonds with one-year maturity. The portfolio is reb...

One hundred years after the original formulation by Petrus J.W. Debije (aka Peter Debye), the Debye Scattering Equation (DSE) is still the most accurate expression to model the diffraction pattern from nanoparticle systems. A major limitation in the original form of the DSE is that it refers to a static domain, so that including thermal disorder usually requires rescaling the equation by a Deby...

OBJECTIVES To introduce a unique system of alias assignment for patients whose identity is initially unknown at time of admission to the emergency unit; to prevent confusion and cases of mistaken identity. METHODS At the triage area the "unknown" patient is given a "forename" using the phonetic alphabet according to the stage of the current name cycle. The sex of the patient is included as we...

OBJECTIVE This is the fourth edition of diagnostic and treatment guidelines for complex regional pain syndrome (CRPS; aka reflex sympathetic dystrophy). METHODS Expert practitioners in each discipline traditionally utilized in the treatment of CRPS systematically reviewed the available and relevant literature; due to the paucity of levels 1 and 2 studies, less rigorous, preliminary research r...

Protocol and technology convergence, the core of near future communication, will soon be forming the interoperating heterogeneous networks. Attaining a strict secure authentication without risking the QoS performance and call success rates is a major concern when it comes to wireless heterogeneous networks. In order to achieve this, a generic, fast and secure, Authentication and Key Agreement p...

Just because you pitch a tent doesn't mean you're ready to go camping. In other words, yes ? men can have erections without feeling sexually excited or horny. These erections, aka spontaneous erections, are perfectly normal and common, popping up when guys are eating dinner, are called on in class, riding a bike, watching a movie, reading, sleeping, talking with grandma, or doing just about any...

We have observed that antidextran hybridomas with potential N-linked glycosylation sites in VH have higher affinity for polymeric dextran and for isomaltoheptaose than those lacking potential glycosylation sites. In these studies we have used gene transfection and expression techniques to verify that the carbohydrate addition sites in VH were used. The carbohydrate of the VH region was accessib...
