Generalized Riesz systems and quasi bases in Hilbert space
2019
The purpose of this article is twofold. First of all, the notion of $(D, E)$-quasi basis is introduced for a pair $(D, E)$ of dense subspaces of Hilbert spaces. This consists of two biorthogonal sequences $\{ \varphi_n \}$ and $\{ \psi_n \}$ such that $\sum_{n=0}^\infty \ip{x}{\varphi_n}\ip{\psi_n}{y}=\ip{x}{y}$ for all $x \in D$ and $y \in E$. Secondly, it is shown that if biorthogonal sequences $\{ \varphi_n \}$ and $\{ \psi_n \}$ form a $(D ,E)$-quasi basis, then they are generalized Riesz systems. The latter play an interesting role for the construction of non-self-adjoint Hamiltonians and other physically relevant operators.
The Study of Dynamic Objects Identification Algorithms Based on Anisotropic Properties of Generalized Amplitude-Phase Images
2018
The article presents some results of dynamical objects identification technology based on coincidence matrixes of templates and tested objects’ amplitude-phase images (APIm) calculated with discrete Hilbert transforms (DHT). DHT algorithms are modeled on basis of isotropic (HTI), anisotropic (HTA), generalized transforms – AP-analysis (APA) and the difference (residual) relative shifted phase (DRSP-) images to calculate the APIm. The identified objects are recognized as members of classes modeled with 3D templates – images of different types airplanes rotated in space. The dynamic anisotropic properties of APIm causes the increasing of sensitivity to circular angle rotation and make possibl…
An Innovative Structural Dynamic Identification Procedure Combining Time Domain OMA Technique and GA
2022
In this paper an innovative and simple Operational Modal Analysis (OMA) method for structural dynamic identification is proposed. It combines the recently introduced Time Domain–Analytical Signal Method (TD–ASM) with the Genetic Algorithm (GA). Specifically, TD–ASM is firstly employed to estimate a subspace of candidate modal parameters, and then the GA is used to identify the structural parameters minimizing the fitness value returned by an appropriately introduced objective function. Notably, this method can be used to estimate structural parameters even for high damping ratios, and it also allows one to identify the Power Spectral Density (PSD) of the structural excitat…

Joubert syndrome (JBTS) and related disorders are defined by cerebellar malformation (molar tooth sign), together with neurological symptoms of variable expressivity. The ciliary basis of Joubert syndrome related disorders frequently extends the phenotype to tissues such as the eye, kidney, skeleton and craniofacial structures. Using autozygome and exome analyses, we identified a null mutation in KIAA0556 in a multiplex consanguineous family with hallmark features of mild Joubert syndrome. Patient-derived fibroblasts displayed reduced ciliogenesis potential and abnormally elongated cilia. Investigation of disease pathophysiology revealed that Kiaa0556 -/- null mice possess a Joubert syndrom…
Novel mutations including deletions of the entire OFD1 gene in 30 families with type 1 orofaciodigital syndrome : a study of the extensive clinical v…
2012
OFD1, now recognized as a ciliopathy, is characterized by malformations of the face, oral cavity and digits, and is transmitted as an X-linked condition with lethality in males. Mutations in OFD1 also cause X-linked Joubert syndrome (JBTS10) and Simpson-Golabi-Behmel syndrome type 2 (SGBS2). We have studied 55 sporadic and six familial cases of suspected OFD1. Comprehensive mutation analysis in OFD1 revealed mutations in 37 female patients from 30 families; 22 mutations have not been previously described including two heterozygous deletions spanning OFD1 and neighbouring genes. Analysis of clinical findings in patients with mutations revealed that oral features are the most reliable diagnos…
Kybertekstien narratologia : digitaalisen kerronnan alkeet
2002
Uudet teknologiat ovat avanneet kertomuksille uudenlaisia tiloja ja mahdollisuuksia. Digitaaliset ohjelmoidut tekstit ovat dynaamisia ja vuorovaikutteisia ja luovat tilanteita, joissa tekstin ja lukijan suhde pysyy jatkuvasti epävakaana. Tällaiset kertomukset haastavat itse kertomuksen käsitteen ja pakottavat ymmärtämään sen uusilla tavoilla. Kybertekstien narratologia selvittää miten ja millaiseksi kerronta ja sitä koskeva teoria muuttuu, voi muuttua ja millaiseksi sen ehkä pitäisi muuttua digitaalisessa mediassa. Tämän vuoksi tutkimuksessa risteytetään toisiinsa kaksi heuristista mallia, Espen Aarsethin kybertekstiteoria ja klassinen narratologia. Näin sijoitetaan niin uudet kuin vanhatki…
"Der Rosenkavalier" (Il Cavaliere della rosa)
2014
Programma di sala della prima proiezione a Palermo del film muto di Robert Wiene "Der Rosenkavalier" (1926), con l'esecuzione delle musiche composte da Richard Strauss. L'autore del contributo ha realizzato anche la traduzione italiana delle didascalie originali del film in lingua tedesca: tale circostanza è segnalata nella locandina dello spettacolo, ma le didascalie non sono state ovviamente pubblicate sul programma di sala.
Molecular and morphological diversity of on-farm hazelnut (Corylus avellana L.) landraces from southern Europe and their role in the origin and diffu…
2013
Hazelnut (Corylus avellana L.) is a traditional nut crop in southern Europe. Germplasm exploration conducted on-farm in five countries (Portugal, Spain, Italy, Slovenia, and Greece) identified 77 landraces. The present work describes phenotypic variation in nut and husk traits and investigates genetic relationships using ten simple sequence repeat (SSR) markers among these landraces, 57 well-known references cultivars, and 19 wild accessions. Among the 77 landraces, 42 had unique fingerprints while 35 showed a SSR profile identical to a known cultivar. Among the 42 unique landraces, morphological observations revealed high phenotypic diversity, and some had characteristics appreciated by th…
