We consider a one-dimensional, transient random walk in a random i.i.d. environment. The asymptotic behaviour of such random walk depends to a large extent on a crucial parameter κ > 0 that determines the fluctuations of the process. When 0 < κ < 2, the averaged distributions of the hitting times of the random walk converge to a κ-stable distribution. However, it was shown recently that in this...

BACKGROUND Esophageal impedance monitoring records changes in conductivity. During esophageal rest, impedance baseline values may represent mucosal integrity. The aim of this study was to assess the influence of acid suppression on impedance baselines in a placebo-controlled setting. METHODS Impedance recordings from 40 infants (0-6 months) enrolled in randomized placebo-controlled trials of ...

cold stress is one of the limiting factors in production of greenhouse vegetables. chemicals offer useful approach to reduce low temperature-induced damages. this study was conducted to evaluate the effect of foliar application of methyl jasmonate (meja) at concentrations of 0 (control), 50, 100, 200 µm) on electrolyte leakage (el), relative water content (rwc), soluble carbohydrates, proline, ...

This paper describes the conceptualization and development of an open source tool for controlling the sound of a saxophone via the gestures of its performer. The motivation behind this work is the need for easy access tools to explore, compose and perform electroacoustic music in Colombian music schools and conservatories. This work led to the adaptation of common hardware to be used as a senso...

We study the multi-frame structure from motion problem when the camera translates on a plane with small baselines and arbitrary rotations. This case shows up in many practical applications, for example, in ground robot navigation. We consider the framework for small baselines presented in [8], in which a factorization method is used to compute the structure and motion parameters accurately, eff...

Results in unsupervised dependency parsing are typically compared to branching baselines and the DMV-EM parser of Klein and Manning (2004). State-of-the-art results are now well beyond these baselines. This paper describes two simple, heuristic baselines that are much harder to beat: a simple, heuristic algorithm recently presented in Søgaard (2012) and a heuristic application of the universal ...
