Thousands of transiting exoplanets have already been detected orbiting a wide range host stars, including the first planets that could potentially be similar to Earth. The upcoming Extremely Large Telescopes and James Webb Space Telescope will enable searches for signatures life in exoplanet atmospheres. Here, we quantify strength spectral features transit indicate biosphere modern Earth on gri...

It is known that multicast is an efficient method of supporting group communication as it allows the transmission of the packets to multiple destinations using fewer network resources. Along with the widespread deployment of the third generation cellular networks and the fast-improving capabilities of the mobile devices, content and service providers are increasingly interested in supporting mu...

Recently Ott, Tomforde and Willis introduced a notion of one-sided shifts over infinite alphabets and proposed a definition for sliding block codes between such shift spaces. In this work we propose a more general definition for sliding block codes between Ott-Tomforde-Willis shift spaces and then we prove Curtis-Hedlund-Lyndon type theorems for them, finding sufficient and necessary conditions...

This paper presents the first results of an empirical study of how players interpret the role of the player and the relationship between the player and playable figures in gameworlds. In the following, we will see examples of four genres that situate the player in different positions with respect to the gameworld. Command & Conquer 3: Tiberium Wars illustrates a game where the player does not h...

This study explores the role of issuance expenses in explaining the fall in stock value for OTC stock offerings that raise cash for debt reduction purposes. It estimates that over half of the sample's −2.79% two-day fall in stock value can be accounted for by issuance expenses when using a lower bound measure of issuance expenses. This estimate contrasts with the one-fifth estimate suggested by...

We present a search-based model of the interbank money market and monetary policy implementation. Banks are subject to reserve requirements and the central bank tenders reserves. Interbank payments redistribute holdings and banks trade with each other in a decentralized (over-the-counter) market. The central bank provides standing facilities where banks can either deposit surpluses or borrow to...
