Retroattività della riforma Brunetta in materia di incentivi?
2013
The author tackles one of the most controversial aspects of the "Brunetta Reform": the knot of effectiveness in the light of the problems of interpretation and application of the novel discipline. This means an examination of the most famous judicial decisions on the application of Article. 65 of the decree in question. In the paper we analyse also the rules and principles laid down in clarification of the reform: the decree n. 141/2011 and the ministerial circulars of 2011.

Efficient extraction and preparative separation of four main isoflavonoids from Dalbergia odorifera T. Chen leaves by deep eutectic solvents-based ne…
2016
In this study, green and efficient deep eutectic solvent-based negative pressure cavitation-assisted extraction (DES-NPCE) followed by macroporous resin column chromatography was developed to extract and separate four main isoflavonoids, i.e. prunetin, tectorigenin, genistein and biochanin A from Dalbergia odorifera T. Chen leaves. The extraction procedure was optimized systematically by single-factor experiments and a Box-Behnken experimental design combined with response surface methodology. The maximum extraction yields of prunetin, tectorigenin, genistein and biochanin A reached 1.204, 1.057, 0.911 and 2.448mg/g dry weight, respectively. Moreover, the direct enrichment and separation of…
ChemInform Abstract: Two New Sesquiterpene Derivatives from the Tunisian Endemic Ferula tunetana Pom.
2010
A new sesquiterpene ester, tunetanin A (1), a new sesquiterpene coumarin, tunetacoumarin A (2), together with eight known compounds, i.e., coladin (3), coladonin (4), isosmarcandin (5), 13-hydroxyfeselol (6), umbelliprenin (7) propiophenone (8), beta-sitosterol (9), and stigmasterol (10), were isolated from the roots of Ferula tunetana. Their structures were elucidated on the basis of extensive spectroscopic methods, including 1D- and 2D-NMR experiments and MS analysis, as well as by comparison with published data. The cytotoxicity of compounds 1-7 towards two human colon cancer cell lines, HT-29 and HCT 116, was evaluated. Compounds 3, 4, and 6 showed weak cytotoxic activities.
Trolling as a Digital Literary Practice in the Russian Language Internet
2020
This article explores trolling as a form of literary activity. It presents a number of specific types of trolling on the Russian-language Internet in connection with digital literature and the literary practices of various groups of Internet users. Techniques for writing provocative “troll-texts” were created and developed within subcultural groups in the 1990s. Later, from being a subversive practice known only to a few insiders, it became a mass technique described in meta-texts that identified rules for trolling and shared facts about its culture with all interested users. In the 2010s, the now popularised techniques of trolling came to be seen as effective strategies to deploy in online…
Can SegFormer be a True Competitor to U-Net for Medical Image Segmentation?
2023
The U-Net model, introduced in 2015, is established as the state-of-the-art architecture for medical image segmentation, along with its variants UNet++, nnU-Net, V-Net, etc. Vision transformers made a breakthrough in the computer vision world in 2021. Since then, many transformer based architectures or hybrid architectures (combining convolutional blocks and transformer blocks) have been proposed for image segmentation, that are challenging the predominance of U-Net. In this paper, we ask the question whether transformers could overtake U-Net for medical image segmentation. We compare SegFormer, one of the most popular transformer architectures for segmentation, to U-Net using three publicl…
