Objective
 The aim of this study was to compare four commonly
 used cytotoxicity assays (XTT, neutral red uptake, crys-
 tal violet assay, and propidium iodide staining) which
 analyzed the antiproliferative effects vitamin K2.
 Material Method
 Saos-2 cells, an osteosarcoma cell line, were
 exposed K2 at different concentrations (10
 μM, 20 30 40 50 100 ...

The published works of scientists often conceal the cognitive processes that led to their results. Scholars of mathematical practice must therefore seek out less obvious sources. This paper analyzes a widely circulated mathematical joke, comprising a list of spurious proof types. An account is proposed in terms of argumentation schemes: stereotypical patterns of reasoning, which may be accompan...

This paper analyzes two joint inference approaches for semantic role labeling: re-ranking of candidate semantic frames generated by one local model and combination of two distinct models at argument-level using meta learning. We perform an empirical analysis on two recently released corpora of annotated semantic roles in Spanish and Catalan. This work yields several novel conclusions: (a) the p...

PURPOSE Prophylactic antibiotics have been used in acute necrotizing pancreatitis with mixed results. This meta-analysis analyzes the effects of prophylactic antibiotics in necrotizing pancreatitis. METHODS Multiple databases and abstracts were searched for randomized trials comparing treatment with prophylactic antibiotics to treatment without prophylactic antibiotics in necrotizing pancreat...

Fully-automated, high-quality MT systems can be developed only if a realistic way to treat meaning in natural languages is found. This paper analyzes a set of positions on the treatment of meaning in machine translation, which we consider the crucial point of difference among MT approaches. We present and criticize a chain of claims that is skeptical with respect to the prospects for meaning-ba...

The need for supporting CSCW applications with heterogeneous and varying user requirements call for adaptive and reconfigurable schedulers accommodating a mixture of real-time, proportional share, fixed priority and other policies, thus overcoming frustrating processor bottlenecks. In this paper we try to overcome this anomaly by proposing an evolutionary strategy for a Meta Hierarchical Schedu...

In this paper we propose a stochastic non-cooperative meta-game approach to assess the role of uncertain CCS deployment on climate agreements among 28 European countries. The game model is identified through statistical emulation of a large set of numerical simulations performed with the computable general equilibrium model GEMINI-E3. In this game the players are the 28 European countries, the ...

Much of the work in today’s organizations is accomplished by distributed, or “virtual” project teams, rather than by work groups meeting in traditional faceto-face meetings. This paper investigates to what extent results from earlier GSS research are being applied to distributed environments, and to what extent more recent research in distributed GSS (DGSS) acknowledges and supports the evoluti...

For a few years and since the release of the expression on Medline in 1992 by Gordon Guyatt et al., interest in the Evidence Based Medicine (EBM) had skyrocketed and had induced a kind of globalization of its teaching. Undoubtedly, we live in the era of EBM in which scientific knowledge and research works are classified in a pyramid hierarchy according to their levels of evidence. At the top of...
