We present an efficient variation of the Local Ensemble Kalman Filter (Ott et al. 2002, 2004) and the results of perfect model tests with the Lorenz-96 model. This scheme is locally analogous to performing the Ensemble Transform Kalman Filter (Bishop et al. 2001). We also include a four-dimensional extension of the scheme to allow for asynchronous observations.

The Web is everywhere in daily life. Business is not possible any more without the fast communication through the web. The knowledge of the humans is reflected in the information accessible in the web. New challenges occur with the flood of information and electronic possibilities for the human being. The current World Wide Web enables an easy, instant access to a vast amount of online informat...

Most previous studies in computerized deception detection have relied only on shallow lexico-syntactic patterns. This paper investigates syntactic stylometry for deception detection, adding a somewhat unconventional angle to prior literature. Over four different datasets spanning from the product review to the essay domain, we demonstrate that features driven from Context Free Grammar (CFG) par...

A number of researchers claim that the derivation of the Right Dislocation Construction (RDC) involves movement (e.g., Chung, 2012, for Korean; Ott & de Vries, 2012, 2015, for Dutch and German; Tanaka, 2001 and Abe, 2004, for Japanese; Whitman, 2000, for English, Japanese, and Korean). However, the RDC in English does not obey movement constraints such as the Coordinate Structure Constraint and...

Social media that allow users to share, create, discuss, and exchange user-generated contents have opened up the potential for co-creation. However, because of social media's the nature of ubiquitous connectivity, customers are involved in a short-term relationship in which customers can choose to interact with multiple firms and switch one firm to another with relatively little effort and cost...

Several authors have treated kinetic effects associated with the ion-acoustic soliton; e.g., Ott and Sudan investigated linear electron Landau damping and Karpman and Lotko have looked at damping due to ion reflection. Here an O'Neil-type frozen wave calculation that includes effects associated with electron orbits in a soliton is presented. This calculation differs from previous ones in that t...

More and more user-generated content is complementing conventional journalism. While we don't think that CNN or New York Times and its professional journalists will disappear anytime soon, formidable competition is emerging through humble Wikipedia editors. In earlier work (Becker 2012), we found that entertainment and sports news appeared on average about two hours earlier on Wikipedia than on...

S ott A. Walla e and John E.

The de nition implies a very stri t orrelation between the agent's knowledge, its mind, and its behavior. Based on this orrelation we argue that a on ise and well{formed re...
