A trending novelty toy that is spun between the fingers induces a striking depth illusion from specular reflections. Further examination of the phenomenon suggests that when surface features are obscured by spinning, depth from disparity of reflections is enhanced.

Some challenges for econometric research on trending time series are discussed in relation to some perceived needs of macroeconomics and macroeconomic policy making. JEL Classi...cation: C32, C53, E10

Twitter1, the microblog site started in 2006, has become a social phenomenon. More than 340 million Tweets are sent out every day2. While a majority of posts are conversational or not particularly meaningful, about 3.6% of the posts concern topics of mainstream news3. Twitter has been credited with providing the most current news about many important events before traditional media, such as the...

This paper presents a method for constructing a specific type of language resources that are conveniently applicable to analysis of trending topics in time-annotated textual data. More specifically, the method consists of building a co-occurrence network from the on-line content (such as New York Times articles) that conform to key words selected by users (e.g., ’Arab Spring’). Within the netwo...

In this paper, a new indicator WARS (Weighted Accumulated Reconstruction Series) at classifying the state of financial market, either trending state or mean-reverting state, was presented. Originated from the computation of Entropy, this new indicator was found to be able to reflect the market behavior accurately and easily. The algorithm of generating WARS and its meaning related to Entropy we...

Feedback and demonstrable local usefulness are critical determinants for adopting event reporting by an organization. The classification schemes used by an organization determine whether an event is recognized or ignored. Near miss events, by their frequency and information content concerning recovery, merit recognition. "Just" cultures are learning cultures that provide a safe haven in which e...

Paleoseismic trenching and fault surface trace mapping indicate that the Olinghouse fault zone, a northeast trending, left-lateral strike-slip fault located in the northern Walker Lane, Nevada, has been the source of multiple latest Pleistocene and Holocene surface-rupturing earthquakes. A trench exposure near the eastern end of the fault records two, and possibly three, earthquakes after 3360 ...

We study a binary classification problem with infinite time series having more than two labels (”event” and ”nonevent” or ”trending” and ”non-trending”). We want to predict the label of the time series given some training data set. Intuitively, the longer we wait, the longer the time series we can observe so that the prediction is more accurate. However, in many applications, such as predicting...

Currently available trend watchers, such as the trends-list on Twitter, are capable of supplying a user of a list of frequently used terms. Such trend watchers are limited because the relationship between trending terms and related terms are not presented, resulting in a minimal understanding why a term is trending. Elvers et al. [2011] proposed a trend watcher that is capable of creating netwo...
