Immunohistochemical expression of Ki-67, Cyclin D1, p16INK4a, and Survivin as a predictive tool for recurrence and progression-free survival in papil…
2019
Objectives: To investigate the expression of several immunohistochemical (IHC) markers and their predictive ability for the recurrence-free and progression-free survival of papillary urothelial bladder cancer (UBC) pTa/pT1 G2 (WHO 1973) compared to classical anatomo-clinical variables using a multidimensional analysis. Materials and Methods: A population-based cohort of 213 primary stage UBC (pTa/pT1) G2 (WHO 1973) was evaluated by classic anatomopathological variables and characterized by immunohistochemistry (23 IHC markers, representative of different oncogenic pathways). The most important variables as a predictor of recurrence-free and progression-free survival were selected using mult…
Changes in the flow and quality of water in the dam reservoir of the Mała Panew catchment (South Poland) characterized by multidimensional data analys…
2023
Multidimensional exploratory techniques, such as the Principal Component Analysis (PCA), have been used to analyze long-term changes in the fl ow regime and quality of water of the lowland dam reservoir Turawa (south-west Poland) in the catchment of the Mała Panew river (a tributary of the Odra). The paper proves that during the period of 1998–2016 the Turawa reservoir was equalizing the river’s water fl ow. Moreover, various physicochemical water quality indicators were analyzed at three measurement points (at the tributary’s mouth into the reservoir, in the reservoir itself and at the outfl ow from the reservoir). The water quality assessment was performed by analyzing physicochemical ind…
Standardizing the analysis of conditioned fear in rodents: a multidimensional software approach
2013
Data comparability between different laboratories strongly depends on the individually applied analysis method. This factor is often a critical source of variation in rodent phenotyping and has never been systematically investigated in Pavlovian fear conditioning paradigms. In rodents, fear is typically quantified in terms of freezing duration via manual observation or automated systems. While manual analysis includes biases such as tiredness or inter-personal scoring variability, computer-assisted systems are unable to distinguish between freezing and immobility. Consequently, the novel software called MOVE follows a semi-automatized approach that prefilters video sequences of interest for…
Multidimensional Analysis of the Distribution of Galaxies with Different Luminosity
1989
We have used the multidimensional or multifractal formalism to study the large scale luminosity segregation of the CfA catalogue. In every sample we have analyzed, it has been found that the spectrum of scaling indices is scale invariant and that bright galaxies are more clustered than faint galaxies.
Weak and Strong Compensation for the Prioritization of Public Investments: Multidimensional Analysis for Pools
2015
Despite the economic crisis still heavily affecting most of Europe, a possible resumption can be found in the revitalization of public and private investments. These investments should be directed not only towards the strategic areas of infrastructures and production, but also to those which allow for a higher level of the quality of life (sports facilities, parks, etc.). In such cases, the need to balance the reasons of financial sustainability with environmental and social profiles is even more evident. Thus, multicriteria techniques, supporting complex assessments, should be implemented together with a monetary feasibility study (cost-benefit analysis). Multidimensional methods allow for…
Study of Wine Producers’ Marketing Communication in Extreme Territories–Application of the AGIL Scheme to Wineries’ Website Features
2020
This study measures the communication ability of wineries in two extreme territories of Southern Italy, Mount Etna and the island of Pantelleria. The evaluation of four dimensions of web communication was carried out by the AGIL Scheme (i.e., adaptation, goal-attainment, integration, latent pattern maintenance). The study provides a generalizable model to be applied in other similar studies. Additionally, focus groups of experts were carried out. The method proved to be suitable to measure the communication effectiveness of wineries through websites. Extreme territories may add value to the wine, regardless of the brand. The heroic wines may become the symbol of these territories, helping e…

The communicative power of an extreme territory – the Italian island of Pantelleria and its passito wine
2018
Purpose This paper aims to examine how Pantelleria’s wineries communicate the extreme territory of Pantelleria through its passito wine and whether this may be a value added for consumers. Specifically examines which dimensions of communication are effectively used by wineries to stimulate, in wine consumers, emotions that link passito wine with the territory of Pantelleria. Design/methodology/approach All websites of wineries producing passito wine in Pantelleria were analyzed using the adaptation, goal-attainment, integration and latent pattern maintenance (AGIL) scheme for measuring communication dimensions. Findings Results suggest that wineries and stakeholders should apply territory-…
Application of Electronic Nose for Evaluation of Wastewater Treatment Process Effects at Full-Scale WWTP
2019
This paper presents the results of studies aiming at the assessment and classification of wastewater using an electronic nose. During the experiment, an attempt was made to classify the medium based on an analysis of signals from a gas sensor array, the intensity of which depended on the levels of volatile compounds in the headspace gas mixture above the wastewater table. The research involved samples collected from the mechanical and biological treatment devices of a full-scale wastewater treatment plant (WWTP), as well as wastewater analysis. The measurements were carried out with a metal-oxide-semiconductor (MOS) gas sensor array, when coupled with a computing unit (e.g., a computer with…
