Pricing of Forwards and Options in a Multivariate Non-Gaussian Stochastic Volatility Model for Energy Markets
2013
In Benth and Vos (2013) we introduced a multivariate spot price model with stochastic volatility for energy markets which captures characteristic features, such as price spikes, mean reversion, stochastic volatility, and inverse leverage effect as well as dependencies between commodities. In this paper we derive the forward price dynamics based on our multivariate spot price model, providing a very flexible structure for the forward curves, including contango, backwardation, and hump shape. Moreover, a Fourier transform-based method to price options on the forward is described.
Stress response in Drosophila subobscura
1988
The pattern of puffing and protein synthesis was determined in individuals of Drosophila subobscura subjected to heat shock. Depending on the extent of the heat treatment, the response at the puffing level varied. Some puffs were expressed at 31°–34°C, and others at 37° C. Considering the response as a whole the depression of gene activity after shock at 31°–34° C in individuals raised at 19° C was greater than with the other treatments. Six major heat shock proteins (Hsps) were found in this species. The properties of the high molecular weight proteins are conserved their electrophoretic characteristics and the range of temperatures over which they are synthesized are close to those in oth…
Il lavoro etero-organizzato prima e dopo il caso Foodora Italia.
2019
l contributo ripropone la discussione sull’esegesi della fattispecie disciplinata dall’art. 1 comma 2 del d. lgs. n. 81 del 2015 (nel testo anteriore alla riforma del 2019) trattata dall’autore nei Colloqui Giuridici sul Lavoro del 2015 (a cura) di Antonio Vallebona per il Massimario di Giurisprudenza del Lavoro. Lo studio rigettava la tesi che il lavoro organizzato dal committente fosse la terza fattispecie e anzi con riferimento delle condizioni di applicazione dimostrava la necessità di una lettura includente. La conclusione era che la nuova disciplina aveva natura antifraudolenta e determinava un allargamento (relativo) dell’area della subordinazione conseguente alla riduzione del cam…
Apical thrombus in a patient with takotsubo cardiomyopathy
2008
We report a case of apical thrombus formation among a group of 15 patients with takotsubo cardiomyopathy who were referred for a suspected acute coronary syndrome over a 2.5-year period. To the best of our knowledge, no data are available regarding the treatment of this syndrome. According to current literature and our reported experience, the use of anticoagulant therapy administered until complete resolution of wall motion abnormalities appears to be appropriate to treat apical thrombus formation and any possible subsequent embolism. © 2008 Italian Federation of Cardiology.
Structure and expression of clustered P element homologues in Drosophila subobscura and Drosophila guanche
1995
Abstract Sequence relationships and functional aspects were analysed in the P element homologues of Drosophila subobscura (Ds) and D. guanche (Dg) . In both species, the P homologues are clustered at a single genomic position. They lack the characteristic terminal structures of actively transposing P elements, but they have the coding capacity for a 66-kDa ‘repressor-like’ protein. Two different types of cluster units (G-type and A-type) can be distinguished. The A-type unit, which is present in multiple copies, is transcribed in adult flies. In contrast, the G-type unit has a much lower copy number and is apparently not expressed. In Dg , the isolated G-type sequence carries a 420-bp inser…
P sequences ofDrosophilla Subobscuralack exon 3 and may encode a 66 kd repressor-like protein
1991
Abstract Several P homologous sequences have been cloned and sequenced from Drosophila subobscura. These sequences are located at the 85DE region of the O chromosome and at least three of them are organized in tandem. We have identified four copies which exhibit strong similarity between them. All of the isolated elements are truncated at the 5' and 3' ends. They have lost the inverted terminal repeats and exon 3, but maintain exons 0, 1 and 2. They are transcribed producing a polyadenylated RNA. The structure of these transcripts suggests that they are able to encode a 66 kd repressor-like protein, but not a functional transposase. We ask about the biological role of a potential repressor …
bilbo, a non-LTR retrotransposon of Drosophila subobscura: a clue to the evolution of LINE-like elements in Drosophila
1997
We used the repetitive character of transposable elements to isolate a non-LTR retrotransposon in Drosophila subobscura. bilbo, as we have called it, has homology to TRIM and LOA elements. Sequence analysis showed a 5' untranslated region (UTR), an open reading frame (ORF) with no RNA-binding domains, a downstream ORF that had structural homology to that of the I factor, and, finally, a 3' UTR which ended in several 5-nt repeats. The results of our phylogenetic and structural analyses shed light on the evolution of Drosophila non-LTR retrotransposons and support the hypothesis that an ancestor of these elements was structurally complex.
Alkaloids Isolated from Somatic Hybrid Cell Cultures of the Species CombinationRauwolfia serpentinaxrhazya stricta
1995
Abstract The phytochemical analyses of a somatic hybrid cell suspension culture of the genus and species combination Rauwolfia serpentina x Rhazya stricta revealed a number of monoterpenoid indole alkaloids. The alkaloids were identified as tubotaiwine, an isomeric mixture of vallesiachotamine, stemmadenine and vomilenine and were all produced in small amounts < 2mg/litre cell suspension. The hybrid cells showed a greater diversity of alkaloid biosynthesis when compared with the parental cultures.
El Teatro Principal de Valencia durante la temporada teatral 1875-1876
2021
El presente artículo revisa toda la actuación operística que hubo en Valencia durante la temporada de 1875 a 1876, la primera que coincide con la restauración de la monarquía de Alfonso XII. A través de la actividad que se produjo en el Teatro Principal de Valencia, examinamos toda la labor operística que hubo en esta ciudad, ya que fue el único lugar donde se representó ópera en Valencia. Una temporada marcada, sin duda alguna, por el estreno de la obra de Verdi, Aida. Un debut que fue posible gracias a la participación del tenor asturiano Lorenzo Abruñedo. Señalamos, asimismo, la importante presencia de la soprano Anna Romilda Pantaleoni, una de las cantantes más sobresalientes en aquel m…
