We prove that a pushing-block puzzle called PUSHPUSH-k is PSPACE-complete for any fixed k ≥ 1. In this puzzle, a robot moves on a finite grid. Each grid position is either empty or occupied by a single obstacle block. While moving, the robot may push obstacle blocks in direction of its movement, subject to certain constraints. In particular, once an obstacle block starts moving, it continues to...

PRELIMINARY AND INCOMPLETE: PLEASE DO NOT CITE Big Push models suggest that local product demand can create multiple labor market equilibria: one featuring high wages, formalization, and high demand and one with low wages, informality, and low demand. I demonstrate that minimum wages may coordinate development at the high wage equilibrium. Using data from 1990s Indonesia, where minimum wages in...

abstract background: pressure ulcer is one of the main concerns of nurses in medical centers around the world, which, if untreated, causes irreparable problems for patients. in recent years, nitric oxide (no) has been proposed as an effective method for wound healing. this study was conducted to determine the effect of nitric oxide on pressure ulcer healing. materials and methods: in this clini...

This paper addresses an experimental investigation in the hydrodynamic behavior of a modified slotted sieve tray. Slotted sieve tray (Push valve sieve tray) is a sieve tray that the push valves have been utilized on the tray deck to eliminate liquid gradients and non-uniformity of liquid distribution on the tray. The air-water system was used in an industrial scale experimental rig with an inte...

The focus of user behavior in the Internet has changed over the recent years towards being driven by exchanging and accessing information. Many advances in networking technologies have utilized this change by focusing on the content of an exchange rather than the endpoints exchanging the content. Network coding and informationcentric networking are two examples of these technology trends, each ...

In this paper we present TROvE (Tool for Rapid OWL Reasoner Evaluation), a tool aimed to offer to a non-expert user the possibility to evaluate OWL reasoners on several reasoning tasks by means of a simple “push-button” solution.

We are now rethinking the idea of electronic democracy. Today nobody is looking at e-democracy from the perspective of a living room, push button, instant referenda democracy, hi the electronic age it is more and more evident that we are facing a complex evolution of the functioning of political systems that democracy is becoming not direct, but continuous; that we can look at an extreme democr...
