The Ways to Russia of Alfredo Casella

The relationship of Alfredo Casella with the Russian musical culture took place on several levels, ranging from artistic interest in the production of \u2018the Five\u2019 to interpersonal relationships that the composer maintained at different times of his life. During his early years in Paris he became passionate about such composers as Musorgsky and Balakirev, which would have much impact on the renewal of the European musical language. In line with the recovery of folklore are the Chansons he arranged in 1912 for a competition organized by the Maison du Lied, an association founded in 1908 in Paris and Moscow that proposed to perpetuate and enrich the tradition of Lied and of popular song. Casella visited St Petersburg with Henri Casadesus\u2019s Soci\ue9t\ue9 des instruments anciens, invited to give concerts of ancient music in 1907-08 and 1909, by Aleksandr Ziloti and Sergey Kusevitsky respectively. Subsequently, in 1926 the composer went to the USSR in order to promote the contemporary music. This trip originated from the relationships he had established with some exponents of Russian musical modernism: Boris Asaf\u2019yev, Viktor Belyayev, and more generally the Association for Contemporary Music\u2019 \u2013 Moscow branch of the International Society for Contemporary Music. The production of the composer was publicized by the group in several issues of their magazine, Contemporary music, and the musician was invited to contribute some writings for the journal. Evidence of these initiatives can be found in some documents preserved at the Casella Archive at the Fondazione Cini in Venice. My contribution will consider these materials, putting them in connection with the existing literature on the Russian musical life in the early years of the 20th century (e. g. Frolova-Walker) and on the activity of Casella in Russia (Lebed\u2019, Kirillina). More importantly, attention will be paid to the critical debate emerging on the mentioned periodical, in reference to the coeval situation within the USSR and in Western Europe. As well as the debate that developed in the 1920s among music theoreticians within the divided community of Soviet musicians, the international contacts upheld among different communities were to be interrupted by the subsequent course of events in the cultural life of the Soviet Union. Still, they represent an element of continuity in the long-standing tradition of Russian \u2013 Italian Musical Connections that are at the centre of the 2018 Conference of the Institute for Russian Music Studies

Positive Impact of Peer Mentorships in the Project Panther LIFE Program

FIU’s Project Panther LIFE is a program that allows students with Intellectual Disabilities to have a full college experience. Project Panther LIFE students receive support from their Academic Mentors and Peer Coaches during the academic year. This study examines the positive impacts of peer relationships between Panther LIFE students and their mentor support system

Замечания о рецепции итальянской оперы seria в период от царствования Анны Иоанновны до царствования Екатерины II

Indagine sulla prima ricezione dell'opera metastasiana in Russia, dal primo contatto con gli spettacoli scenico-musicali italiani (anni Trenta del Settecento) fino all'emergenza di precoci istanze di ordine nazionale (P. Plavil'ščikov) alla vigilia del torno di secolo

Sending femtosecond pulses in circles: highly non-paraxial accelerating beams

We use caustic beam shaping on 100 fs pulses to experimentally generate non-paraxial accelerating beams along a 60 degree circular arc, moving laterally by 14 \mum over a 28 \mum propagation length. This is the highest degree of transverse acceleration reported to our knowledge. Using diffraction integral theory and numerical beam propagation simulations, we show that circular acceleration trajectories represent a unique class of non-paraxial diffraction-free beam profile which also preserves the femtosecond temporal structure in the vicinity of the caustic

Arbitrary non-paraxial accelerating periodic beams and spherical shaping of light

We report the observation of arbitrary accelerating beams designed using a non-paraxial description of optical caustics. We use a spatial light modulator-based setup and techniques of Fourier optics to generate circular and Weber beams subtending over 95 degrees of arc. Applying a complementary binary mask also allows the generation of periodic accelerating beams taking the forms of snake-like trajectories, and the application of a rotation to the caustic allows the first experimental synthesis of optical accelerating beams upon the surface of a sphere in three dimensions.Comment: 4 pages, 4 figures articl

Characterization of seed proanthocyanidins of thirty-two red and white hybrid grape varieties

Grape seed extracts are known for their beneficial effects on health and on cardiovascular diseases due to antioxidant activity and the free radical-scavenging properties of proanthocyanidins (PAs). Moreover, grape seed tannins are used in oenology as additives to improve the organoleptic characteristics of wines, and for the clarification of must and wines. PAs in seed extract of 32 hybrid and three V. vinifera grape varieties were characterized by MALDI-TOF mass spectrometry. Signals of 148 compounds were identified as [M+H]+, [M+Na]+ and [M+K]+ adducts of B-type and A-type PAs formed from catechin/epicatechin subunits up to undecamers and with galloylation degree 0-7. The number-average molecular weight (Mn) of the samples, a parameter correlated with the molecular weight of polymers, and the polyphenolic content of extract, were also determined. Profiles of the hybrid grape varieties were compared with those of three V. vinifera samples studied as references. 'Terzi 108-6' showed high content of antioxidant polyphenols and 'Seyve Villard 12-390' higher content of higher oligomers. These two grape varieties are therefore potentially very interesting as sources of antioxidants and tannins for nutraceutical and oenological uses

Security challenges of small cell as a service in virtualized mobile edge computing environments

Research on next-generation 5G wireless networks is currently attracting a lot of attention in both academia and industry. While 5G development and standardization activities are still at their early stage, it is widely acknowledged that 5G systems are going to extensively rely on dense small cell deployments, which would exploit infrastructure and network functions virtualization (NFV), and push the network intelligence towards network edges by embracing the concept of mobile edge computing (MEC). As security will be a fundamental enabling factor of small cell as a service (SCaaS) in 5G networks, we present the most prominent threats and vulnerabilities against a broad range of targets. As far as the related work is concerned, to the best of our knowledge, this paper is the first to investigate security challenges at the intersection of SCaaS, NFV, and MEC. It is also the first paper that proposes a set of criteria to facilitate a clear and effective taxonomy of security challenges of main elements of 5G networks. Our analysis can serve as a staring point towards the development of appropriate 5G security solutions. These will have crucial effect on legal and regulatory frameworks as well as on decisions of businesses, governments, and end-users
