Nelo Risi analyzed closely
No full textNella prima sezione di questo testo si analizzano le “esperienze” che stanno all’origine del lavoro di Nelo Risi. La trama dei punti di vista che s’irradiano nelle opere successive è il tema delle altre sezioni, dove sono messe in evidenza le occasioni pubbliche e private che forgiano la particolare forma espressiva e la magnetica memorabilità dello stile di Risi. La novità di questo percorso, in parte già noto, sta nel presentare l’autore seguendo il filo di un’inedita documentazione epistolare e iconografica, una “corrispondenza” d’intrecci e motivi che talvolta diventano ravvicinati, perché sarà la parola di Risi a irrompere dai fogli di un carteggio, mostrando come in uno specchio il suo profilo di uomo e di poeta.The first section of this text analyzes the “experiences” that give rise to Nelo Risi’s work. The remaining sections first examine the weaving of perspectives in his subsequent works, and secondly underscore the public and private occasions which shape the particular expressiveness and magnetic memorability of Risi’s style. This study is original in that it introduces the author by following the thread of an unpublished epistolary and iconographical documentation, a “correspondence” of intertwined strands and motifs that sometimes converge to each other. Risi’s word will definitively break out from the papers of such correspondence by showing his profile of both man and poet as if they were reflections from a mirror

Isotope-enabled large-eddy simulation outputs
No full textThis dataset includes the outputs from 11 isotope-enabled large-eddy simulations.
Simulations are done with the System for Atmospheric Modeling (SAM) non-hydrostatic model.
The control simulation ("ctrl") is three-dimensional, with a doubly-periodic domain of 96 km x 96 km. The horizontal resolution is 750 m. There are 96 vertical levels. The simulation is run in radiative-convective equilibrium over an ocean surface with a sea surface temperature (SST) of 30°C.
In two other simulations, the imposed SST is varied (26°C, 33°C): "26C" and "33C".
In five other simulations, a large-scale vertical velocity forcing is imposed:
- large-scale vertical velocity of -60hPa/d peaking at 500hPa: "omegaLSm60"
- large-scale vertical velocity of -20hPa/d peaking at 500hPa: "omegaLSm20"
- large-scale vertical velocity of +20hPa/d peaking at 500hPa: "omegaLS20"
- large-scale vertical velocity of -60hPa/d peaking at 400hPa: "p400"
- large-scale vertical velocity of -60hPa/d peaking at 600hPa: "p600"
A simulation similar to "ctrl" is run with a horizontal resolution of 200m over a domain of 25.6 x 25.6km: "200m".
Two simulations are similar to "ctrl" and "omegaLSm60" but without isotopic fractionation during rain evaporation: "ctrl_nofracrev" and "omegaLSm60_nofracrev".
Outputs for simulations used in Risi et al 2020 include 1D variables and 3 variables in the lower troposphere. Outputs for simulations in Risi et al 2021 include 3D variables covering the full troposphere
Studying abbreviated vs. full-word identifier names when dealing with faults: An external replication
No full textContext: abbreviated and full-word identifier names in dealing with faults in source code. Goal: investigating whether the use of abbreviated identifier names affects the ability of novice professional software developers in identifying and fixing faults in Java code. Method: external replication. Results: the results of the original experiment (conducted on C code) were confirmed. Conclusions: the difference in using abbreviated and full-word identifiers is not statistically significant with respect to the time to complete a task and the number of faults identified and fixed
Description of the final instar larva of Cephalaeschna risi Asahina, 1981 with notes on its semi-terrestrial lifestyle (Odonata: Aeshnidae)
No full textThe final instar larva of Cephalaeschna risi Asahina, 1981 is described for the first time based on material from Taiwan. In Taiwan, the larva of C. risi can be separated from other aeshnid larvae by its relatively short antennae and presence of small protuberances on the legs. Diagnostic characters to distinguish it from other known larvae of Cephalaeschna are also discussed. A com prehensive description, detailed illustrations, bionomics and observations of the semi-terrestrial life style of C. risi are presented. Finally, a key to the genera of Aeshnidae in Taiwan is proposed
Using the normalized levenshtein distance to analyze relationship between faults and local variables with confusing names: A further investigation
No full textThis paper exploits further uses of NLD (Normalized Levenshtein Distance), proposed in a recent study, to quantify the level of confusion of variables with the aim of verifying if they can provide indications about the presence of faults. We provide further evidence that fault prediction models based on the considered NLD measures can provide accurate estimations

No full textA graph-based approach to detect unreachable methods in Java software
No full textIn this paper, we have defined a static approach named DUM (Detecting Unreachable Methods) that works on Java byte-code and detects unreachable methods by traversing a graph-based representation of the software to be analyzed. To assess the validity of our approach, we have implemented it in a prototype software system. Both our approach and prototype have been validated on four open-source software. Results have shown the correctness, the completeness, and the accuracy of the methods that our solution detected as unreachable. We have also compared our solution with: JTombstone and Google CodePro AnalytiX. This comparison suggested that DUM outperforms baselines
Studies on organic synthesis through sustainable catalysis
No full textToday the development of sustainable processes in the chemical industry is critical, and Green Chemistry represents an evolution from the conventional concepts of process efficiency. Twenty years ago, Paul Anastas and John Warner introduced this concept within the twelve principles. In this work, many aspects the twelve principles are applied, developing sustainable methods involving the use of metal catalysis and biocatalysis through one pot and cascade reactions.In the first part of the PhD period, the use of the micellar catalysis was investigated, to perform reactions in water avoiding (or limiting) the use of the traditional organic solvents. The possibility to apply the micellar conditions for the hydrogen borrowing (HB) reaction to prepare amines was explored. Different Ru catalysts were screened using water as medium, under Microwave (MW) dielectric heating. Once optimized, the scope of the reaction was investigated using differently substituted amines and alcohols. Besides, the use of a biomass-derived solvent (GVL) was explored in Pd/C catalysed transformations to avoid the arching phenomena frequently observed using conventional solvents (e.g. toluene). A sustainable protocol for the synthesis of benzimidazoles employed different aliphatic and aromatic amines through a hydrogen transfer Pd/C. A heating profile and various studies of stability have been reported. A biocatalytic approach to pyridine and furans is also reported. These heterocycles are fundamental building blocks for the synthesis of pharmaceuticals, agrochemicals and organic material. Furthermore, these compounds are also employed in flavour and fragrance industry owing to their peculiar olfactory properties. Classical methodologies for their synthesis are based on low-yielding multistep methods, which involve the use of harsh conditions. Therefore, novel mild and greener methodologies for the preparation of heterocycles compounds are highly desirable. Aromatization of substituted 1,2,3,6-tetrahydropyridines (THPs) was performed using whole-cell monoamine oxidase MAO-N (variants from Aspergillus niger) catalyst. The aromatization of the tetrahydropyridine starting materials into the pyridine products was monitored through 1H NMR spectroscopy. During the optimization, different pyridine compounds are prepared to screen the best co-solvents and MAO-N variants. The kinetic profile of the biocatalytic transformation by MAO-N was also monitored via in situ 19F NMR experiments. Aromatization of different 2,5-dihydrofurans into corresponding furans was also performed using the Laccase/TEMPO catalytic system using mild conditions. A chemo- enzymatic cascade reaction starting directly from acyclic aliphatic precursor has been developed
showing that metathesis Grubb's catalyst and the Laccase/TEMPO system can be used in combination for an efficient protocol
