A short survey on Lie theory and Finsler geometry
2017
The aim of this chapter is to provide readers with a common thread to the many topics dealt with in this book, which is intermediate and which aims at postgraduate students and young researchers, wishing to intrigue those who are not experts in some of the topics. We also hope that this book will contribute in encouraging new collaborations among disciplines which have stemmed from related problems. In this context, we take the opportunity to recommend the book by Hawkins [18]. A basic bibliography is outlined between the lines.

Seroprevalence of Norovirus Genogroup IV Antibodies among Humans, Italy, 2010–2011
2014
Antibodies specific to genogroup IV identified in human specimens suggest zoonotic exposure.
Role of SH-Groups and S-S Bridges in the Main Subunit (1/12 Molecule) of Spirographis Spallanzanii Chlorocruorin
1986
In all species of annelids described, the extracellular hemoglobins show (by electron microscopy) the same quaternary structure constituted by twelve identical subunits. The fine structure of the 1/12 subunit is not well resolved and several models have been proposed for it (2).
Potentialgesteuerte SS-Bindungsspaltung und Fluoreszenzmarkierungsstudien am Beispiel des Rinderinsulins
1985
Die drei SS-Brucken im Insulin konnen galvanostatisch unter Bildung der SH-A-Kette und der SH-B-Kette (Produktgemisch I) aufgespalten werden. Potentiostatisch gelingt bei -1.3 V (vs. SCE) die selektive Offnung der zwei interchenaren Disulfidbrucken (Produktgemisch II). Die vier SH-Gruppen im Produktgemisch II werden mit dem Vinylsulfon 1 blockiert (Produktgemisch III). Im Produktgemisch III wird die intrachenare Disulfidbrucke in der teilblockierten A-Kette bei -1.8 V (vs. SCE) potentiostatisch reduktiv geoffnet und mit dem fluoreszierenden Arylvinylsulfon 2 geschutzt (Produktgemisch IV). Auch die SH-Gruppen in den Produktgemischen I und II werden durch die fluoreszierenden Vinylsulfone 2 u…
Gezielte und reversible Fluoreszenzmarkierung von SH-Lysozym mit Vinylsulfonen
1985
Am Beispiel von SH-Lysozym wird gezeigt, wie man SH-Gruppen reversibel mit den Vinylsulfonen 1–4 nach Gl. (a) selektiv blockieren und nach Gl. (b) selektiv deblockieren kann. Das wasserlosliche Vinylsulfon 2 macht das blockierte SH-Lysozym wasserloslich. Durch Einwirkung von NaOH-Losung wird nach Gl. (b) das wasserunlosliche SH-Lysozym regeneriert. Die fluoreszierenden Vinylsulfone 3 und 4 konnen als Fluoreszenzmarker nach verschiedenen Arbeitsweisen zum qualitativen Nachweis und zur quantitativen Bestimmung von SH-Gruppen herangezogen werden. Selective and Reversible Fluorescence Marking of SH-Lysozyme with Vinyl Sulfones The SH groups of SH-lysozyme as a model substance are selectively bl…
Interazioni tra migranti e popolazioni locali nella Sicilia centrale del IV sec. a.C.
2017
The contribution concern the hinterland of Sicily in the 4th century BC, particularly the part delimited by the rivers Halykos and Himeras, inhabited by the Sicans since prehistoric times. The few testimonies of the historical sources about this population of anellenic origin for the given period are compared to the news derived from the analysis of numismatic documents found in the territory in the contest of 4th century BC. The analysis will allow to take account of the prevailing conservatism of these communities, despite interactions with the peninsular groups established in this part of the island in the second half of the 4th century a.C.
LA COMPLESSA STRADA VERSO L’INNOVAZIONE NEI TERRITORI
2015
This paper provides a framework on regional research systems, through which, different regions are preparing to engage in program- ming period 2014 – 2020. It will also cover the regions’ investments in the co-financed programs between 2000 and 2013. Particular attention is dedicated to those projects that, in the specific objectives or specific actions have referred to high-tech districts, techno- logical platforms, clusters, innovation centers, science or technology parks and networks. It then carries out two verifications: firstly, of the degree of consistency between policies and implementation and ongoing design (S3) and secondly of their connection with the existing territorial specia…

In this article we apply the S(M, g)–calculus of L. Hormander and, in particular, results concerning the spectral invariance of the algebra of operators of order zero in ℒ(L2(ℝn)) to study generators of Feller semigroups. The core of the article is the proof of the invertibility of λ Id + P for a strongly elliptic operator P in Ψ(M, g) and suitable weight functions M and metrics g. The proof depends highly on precise estimates of the remainder term in asymptotic expansions of the product symbol in Weyl and Kohn–Nirenberg quantization. Due to the Hille–Yosida–Ray theorem and a theorem of Courrege, the result concerning the invertibility of λ Id + P is applicable to obtain sufficient conditio…
