Children playing music by Francesco Pollini (April 2016)
Radovan Škrjanc, member of the Slovenian partner group of the MusMig project and author of the critical music edition of three sonatas by a migrant musician Francesco Pollini (* Ljubljana 1762 , † Milan 1846) published in the series of Monumenta artis musicae Sloveniae in 2014, has been involved also in promoting Pollini’s music within larger musical circles, especially music schools. In April 2016 two events with children playing Pollini is to take place in Ljubljana. On April 6th there was ..
Persistent Coverage Control for Teams of Heterogeneous Agents - Extended Version
A distributed cooperative control law for persistent coverage tasks is
proposed, capable of coordinating a team of heterogeneous agents in a
structured environment. Team heterogeneity is considered both at vehicles'
dynamics and at coverage capabilities levels. More specifically, the general
dynamics of nonholonomic vehicles are considered. Agent heterogeneous sensing
capabilities are addressed by means of the descriptor function framework, a set
of analytical tools for controlling agents involved in generic coverage tasks.
By means of formal arguments, we prove that the team performs the task and no
collision occurs between agents nor with obstacles. A numerical simulation
validates the proposed strategy

Vision-based relative navigation system for autonomous proximity orbital operations
The paper presents the research project of the author, focused on developing, implementing and testing a vision based relative navigation system for spacecraft. A temporal organization of the project is presented, with tasks assigned to each year of the PhD programme, while at the same time two main technical stages, “final” and “far” rendezvous are introduced together with their scientific objectives. Being an experimental work, the envisioned implementation of the system on COTS computing platforms is introduced as well as the experiments planned to gather real imagery to validate the algorithms. Finally, possible fields of application of the project are discussed
Characterization of plasmid pAX22, encoding VIM-1 metallo-β-lactamase, reveals a new putative mechanism of In70 integron mobilization
Objectives: VIM-type enzymes are among the most widespread acquired metallo-β-lactamases among Gramnegative pathogens. Integron In70 is a class 1 integron that has emerged as a successful genetic support for blaVIM-1 (one of themostprevalent blaVIM allelic variants) in Gram-negativenon-fermenters, andis usually chromosome borne. The objective of this study was to characterize plasmid pAX22 from Achromobacter xylosoxidans AX22, which represents the only In70-harbouring plasmid known so far, to gather insights into the mechanisms of evolution and dissemination of In70-like elements. Methods: The complete sequence of pAX22was obtained by pyrosequencing and assembled with Roche Newbler software. The draft sequence, completed using a PCR-based strategy, was annotated via the BASys tool and compared with known sequences using BLAST algorithms. Results: The backbone of pAX22 showed significant similarity with that of pNOR-2000, a blaVIM-2-harbouring plasmid from Pseudomonas aeruginosa, and with the TnCP23 transposon. The three elements differed from each other mainly by the class 1 integron cassette arrays and by some integron-associated structures. In pAX22, In70was associated with a novel putative transposon, Tn7017, composed of a defective Tn402-like transposon carrying In70 and the ISPa17 insertion sequence. Conclusion: Plasmid pAX22 belongs to a lineage of plasmids circulating among Gram-negative non-fermenters. In70 was probably acquired by pAX22 by transposition of Tn7017, revealing a novel putative mechanism of In70 mobilization. Our results highlight the potential role that ISPa17couldhave in mobilizing defective Tn402-like transposons carrying class 1 integrons. © The Author 2013.

An efficient approach to chiral nonracemic trans- and cis-decalin scaffolds for drimane and labdane synthesis
Optically active trans - and cis -ring junction decalinic intermediates, which represent useful precursors for the synthesis of more complex natural targets, have been conveniently prepared starting from the β-ketoester obtained by standard chemistry from β-ionone and dimethyl carbonate. The chiral auxiliary (−)-menthol, easily attached to the β-ketoester through DMAP-catalyzed transesterification, allowed a clean separation of the diastereomers obtained in the key electrocyclization step, which were further elaborated to chiral intermediates already taken to drimane and labdane sesquiterpenes
A New Approach to Kainoids through Tandem Michael Reaction Methodology: Application to the Enantioselective Synthesis of (+)- and (−)-α-Allokainic Acid and to the Formal Synthesis of (−)-α-Kainic Acid
A convergent, one-pot construction of functionalized pyrrolidine ring systems has been developed. The method is based on a tandem Michael reaction initiated by an intermolecular conjugate addition of a nitrogen nucleophile to an electrophilic olefin followed by trapping of the generated enolate by a built-in α,β-unsaturated acceptor. After model studies verified the feasibility of the process and gave information about its stereochemical outcome, the strategy was successfully applied to kainoid synthesis. The construction of the basic pyrrolidine skeleton of all the members of the family requires coupling of a suitable electrophilic subunit with a common donor‒acceptor fragment containing the nitrogen nucleophile. Thus, the enantioselective synthesis of (+)-α-allokainic acid (2) and the formal synthesis of its C-4 epimer (-)-α-kainic acid (1), have been accomplished using methyl vinyl ketone and 2-nitro-3-methyl-1,3-butadiene, respectively, as electrophilic partners of (S)-4-(benzylami..
