Degenerate Riemann theta functions, Fredholm and wronskian representations of the solutions to the KdV equation and the degenerate rational case
2021
International audience; We degenerate the finite gap solutions of the KdV equation from the general formulation given in terms of abelian functions when the gaps tend to points, to get solutions to the KdV equation given in terms of Fredholm determinants and wronskians. For this we establish a link between Riemann theta functions, Fredholm determinants and wronskians. This gives the bridge between the algebro-geometric approach and the Darboux dressing method.We construct also multi-parametric degenerate rational solutions of this equation.

Virtual and augmented reality: Advancing research in consumer marketing
2020
Abstract Virtual reality (VR) and augmented reality (AR) technologies are having a profound impact on a variety of marketing practices and are attracting increasing attention from marketing researchers. In this article, we review developments in VR/AR applications and research in the area of consumer marketing. We propose a conceptual framework for VR/AR research in consumer marketing that centers around consumer experiences provided by VR/AR applications along the customer journey and the effectiveness of such applications, and delve into the key concepts and components of the framework. Next, we provide a comprehensive overview of VR/AR applications in current practices and extant researc…
Evaluating Dance Consumption through the Experiential Value Approach
2018
Purpose – The experiential paradigm has been confirmed as a valuable means to explore and understand people’s consumption of cultural services, thus drawing an increasing interest in the marketing and consumer behavior literature. In this context, consumers’ behavioral decisions are considered not as merely functional but also strongly influenced by emotional dimensions and intrinsic aspects. As consumption of arts is strongly associated with feelings, the experiential approach is a valuable lens for exploring and understanding individuals who consume cultural services. This paper therefore adopts the experiential approach to assess dance as a consumption experience, which is meant to be in…
Numerical study of shock formation in the dispersionless Kadomtsev-Petviashvili equation and dispersive regularizations
2013
The formation of singularities in solutions to the dispersionless Kadomtsev-Petviashvili (dKP) equation is studied numerically for different classes of initial data. The asymptotic behavior of the Fourier coefficients is used to quantitatively identify the critical time and location and the type of the singularity. The approach is first tested in detail in 1+1 dimensions for the known case of the Hopf equation, where it is shown that the break-up of the solution can be identified with prescribed accuracy. For dissipative regularizations of this shock formation as the Burgers' equation and for dispersive regularizations as the Korteweg-de Vries equation, the Fourier coefficients indicate as …
Development of a modified DNA extraction method for pulsed-field gel electrophoresis analysis of Staphylococcus aureus and enterococci without using …
2010
A modified pulsed-field gel electrophoresis (PFGE) protocol was developed and applied to clinical isolates of Staphylococcus aureus and enterococci to reduce the cost of using lysostaphin. This protocol reduces the expenses of PFGE typing of S. aureus and enterococci as it removes the use of lysostaphin during the spheroplast formation from these bacteria.

Test di lunga durata dalla rete di stazioni permanenti UNIPA della Sicilia
2010
La sperimentazione riportata in questo lavoro è volta ad analizzare le influenze che hanno i test di lunga durata sulla precisione e sulla ripetibilità delle misure. Vengono valutati differenti schemi di rete per il calcolo delle correzioni differenziali partendo dall’applicativo software in uso al Dipartimento di Rappresentazione dell’Università di Palermo, GNSMART Geo++, con particolare riferimento alla interdistanza e alla presenza di stazioni all’interno della rete. Complessivamente sono stati condotti rilievi statici per un arco temporale di 40 ore, su un punto di coordinate note posto sul terrazzo del Dipartimento e per ogni schema di calcolo proposto si sono effettuate quattro sessio…
The effects of cors network geometry and differential nrtk corrections on gnss solutions
2021
The widespread availability of Continuosly Operating Reference Station (CORS) all over the world, allows to improve more scientific and technical studies on the use of satellite positioning techniques. The aim of this paper is to understand the effects of a GNSS CORS network geometry and differential corrections on the solutions. The analysis is carried out using ten different network configurations, with different inter-distances between the stations within GNSMART Geo++ software. The coordinates of one control point placed on the top of the Department of Engineering (University of Palermo, Italy) have been used to perform several static positioning mode test within fourthy hours. Differen…
