Transputer-based parallel system for acquisition and on-line analysis of single-fiber electromyographic signals.
1992
Abstract We describe a transputer-based system suitable for accurate measurements of single-fiber electromyographic jitter. It consists of a conventional electromyograph, a home-made interface and a commercially available transputer-based board installed within a PC/AT compatible. Taking advantage of the concurrent operation of two transputer modules, the system features simultaneous data acquisition and statistical signal processing: while data are acquired and analyzed, a real-time visualization of the signal latency and its variability is provided. In the present configuration, the system can acquire and analyze up to 40,000 consecutive action potentials, which can be grouped into up to …
Objective evaluation of the width of source ensemble in virtual halls
2012
[EN] In this work, we study the effects of the width of the sound source in several acoustical virtual room models with different topologies, sizes and uses, calibrated with commercial software. To achieve this aim, a square distribution of sound sources with variable side length has been considered. We have auralized four channels of speech signal and musical signal in three different locations in each room. By using signal processing techniques, a comparison of multisource auralizations with the ones obtained from a single source in the middle of the stage is made. Also, the variations between the usual room parameters obtained from these simulations are analyzed, in order to show the eff…
Synthesis and Biological Evaluation of Organometallic Complexes Bearing Bis‐1,8‐naphthalimide Ligands
2018
Organometallic N-heterocyclic carbene (NHC) complexes with intercalating bis-naphthalimide ligands were prepared and evaluated biologically. Cytotoxic effects against tumor cells or bacteria were strongly ligand dependent with minor influence of the metal (Ag, Ru, Rh, Au) centers. Complex 8b with a rhodium(I) NHC moiety was studied in more detail for its DNA interacting properties in comparison to the metal free ligand. These studies showed a good DNA binding pattern with some preference for the telomeric quadruplex structure hTelo. Complex 8b was also shown to trigger additional coordinative binding to the DNA and therefore represents an useful tool compound with a mixed intercalative/coor…
A new decision model for economic evaluation of novel therapies for HCV
2014
In 2014, the European Medicines Agency (EMA) has given the license to two new direct-acting antiviral: sofosbuvir and simeprevir. The evidence provided by the studies, reported a high rate of SVR even in patients with decompensated cirrhosis. This and other innovative elements are potentially adept at changing the entire natural course of HCV. However, the dramatic prevalence rates of HCV observed in Italy, and the high prices that are expected to be required by the pharmaceutical industry, raises some critical issues about how to regulate access to such drugs. The objective of this article is to present a new decision model for the evaluation of novel therapies for HCV. This model is inten…
'Apparently, women don't know how to operate doors': a corpus-based analysis of women stereotypes in the tv series 3rd Rock from the Sun
2017
This paper explores how women stereotypes are discursively evaluated in the TV sitcom 3 rd Rock from the Sun by paying attention to the societal, cultural and ideological values they convey. Following recent trends for the study of television series (Bednarek, 2010), the analysis is both qualitative and quantitative, adopting a Corpus- Assisted Discourse Analysis approach (Baker, 2006; Partington, 2004). The contextualised analysis of words that refer to women confirms that the sitcom writers of 3 rd Rock from the Sun purposefully resort to stereotyping as a verbal strategy to create humour while conveying negative attitudes towards women.
Contrasting Norway spruce disturbance dynamics in managed forests and strict forest reserves in Slovakia
2022
Abstract Forest disturbances are intensifying globally, yet regional drivers of these dynamics remain poorly understood. We investigated recent disturbance intensities in Norway spruce (Picea abies L.) forests in Slovakia (Central Europe) with different management objectives in 2000–2017 based on Landsat imagery. We focused on 122 strict reserves without any management, their actively managed surroundings (500 m and 2000 m buffers), and managed production forests beyond the buffer areas. We used generalized additive mixed models to test for differences in temporal trends of disturbance intensity among these management categories. We found that disturbance intensity was increasing in all man…
Radiation Hardness Assurance Through System-Level Testing: Risk Acceptance, Facility Requirements, Test Methodology, and Data Exploitation
2021
International audience; Functional verification schemes at a level different from component-level testing are emerging as a cost-effective tool for those space systems for which the risk associated with a lower level of assurance can be accepted. Despite the promising potential, system-level radiation testing can be applied to the functional verification of systems under restricted intrinsic boundaries. Most of them are related to the use of hadrons as opposed to heavy ions. Hadrons are preferred for the irradiation of any bulky system, in general, because of their deeper penetration capabilities. General guidelines about the test preparation and procedure for a high-level radiation test ar…
Ex-Ante Business Model Evaluation Methods: A Proposal of Improvement and Applicability
2019
[EN] Purpose: The purpose of this paper is to choose the best method for ex ante business model evaluation, improve it and provide a framework to put it into practice. Design/Methodology/Approach: After an in-depth review, we chose the best method for ex ante business model evaluation, improved this method, and applied it to a real case study in which business models had been proposed for a Sustainable Smart District project. Findings: We analysed existing ex ante business model evaluation methods, justifying our choice of the best one. We improved this key question-based method by combining classic management tools and a new, promising procedure. We finally found a strong tool to improve b…

Assimilation and Contrast in Spontaneous Comparisons: Heterogeneous Effects of Standard Extremity in Facial Evaluations
2020
Judgments we make about others often depend on the standards we use as comparisons. Investigations into the outcomes of these comparisons and potential moderators have often been limited to single dimensions and preselected standards. The current work instead uses multiple evaluative facial dimensions and a multitude of comparisons. A series of 4 experiments ('N' = 665) attempted to detect contrast from extreme (Study 1) and assimilation to moderate standards in within (Studies 2 and 3) and between-subjects designs (Study 4). Results showed inconsistent evidence for both comparison effects and significant heterogeneity across the evaluative dimensions that were sampled. An additional 5 stud…
