Induction of premature (stress induced) cellular senescence of normal cells provides the mechanism eliminating proliferative capability of potentially carcinogenic cells and thereby is considered to be a barrier preventing neoplastic tranformation [1]. On the other hand, induction of senescence in tumor cells provides a therapeutic opportunity to treat cancers that may be potentially susceptibl...

While subsidised populations of feral cats are known to impact their prey populations, little is known about the ecological impact of inside/outside hunting cats (IOHC). We studied IOHC around a suburban nature preserve. Mail surveys indicated an average of 0.275 IOHC/house, leading to a regional density estimate of 0.32 IOHC/ha. A geographical model of cat density was created based on local ho...

Feral cats (Felis catus) have spread throughout anthropogenic and insular environments of the world. They now threaten many species of native wildlife with chronic depredation. Knowledge of feral cat population dynamics is necessary to understand their ecological effects and to develop effective control strategies. However, there are few studies worldwide regarding annual or lifetime survival r...

In this paper we model the multicointegration relation, allowing for one structural break. Since multicointegration is a particular case of polynomial or I(2) cointegration, our proposal can also be applied in these cases. The paper proposes the use of a residualbased Dickey-Fuller class of statistic that accounts for one known or unknown structural break. Finite sample performance of the propo...

We have prototyped a multimedia tool to visualize the readiness of US Army War Reserve equipment. In contrast to previous efforts, our system allows the readiness to be visualized across several dimensions and to mediate existing heterogeneous data sources. Our front end Java applet enables multimedia and multidimensional visualization and allows a small client to access the mediation server fr...

Moderne Tablet PCs erscheinen aufgrund kurzer Ladezeiten, hoher Benutzerfreundlichkeit und ihrer natürlichen Integration in den Vorlesungssaal als ideale Werkzeuge im Mobile Learning. Es existieren jedoch nur wenige Studien, welche die Auswirkungen des Einsatzes von Tablet PCs im Hinblick auf Zufriedenheit und Aktivierung der Lernenden direkt mit klassischen Laptops vergleichen. Um diese Forsch...

Fast hundert Jahre nach der Vorhersage von Neutrinos sind wir heute in Lage, diese faszinierenden Elementarteilchen als Boten aus dem All zu nutzen. Sie helfen uns, die extremsten Phänomene im Universum verstehen. IceCube ist das erste Neutrinoteleskop, kritische Größe erreicht hat, um Neutrinosignale messen. Damit lassen sich Schlüsse über ihre Herkunft und Eigenschaften ihrer Quellen ziehen. ...

Robotic exploration of remote areas to assist or replace human exploration reduces the cost, hazard and tedium of such exploration. For remote explorers, power is the most critical resource, and the most common source of that power is solar energy. Information about the robot configuration, the planned path, the terrain and the position of the sun can be processed by a solar power expert softwa...

With the notable exception of his paleolithic feminism,1 Stanisław Lem (1921–2006) was a twenty-first-century writer writing in twentieth century. As early as 1960s, he anticipated much twenty-first century's information technology and biotechnology—tablets, personal computers, smart phones, eBooks, virtual reality, artificial intelligence, robotics, holograms, advanced prosthetics, human-machi...
