Eukaryotic snoRNAs: a paradigm for gene expression flexibility.
2009
AbstractSmall nucleolar RNAs (snoRNAs) are one of the most ancient and numerous families of non-protein-coding RNAs (ncRNAs). The main function of snoRNAs – to guide site-specific rRNA modification – is the same in Archaea and all eukaryotic lineages. In contrast, as revealed by recent genomic and RNomic studies, their genomic organization and expression strategies are the most varied. Seemingly snoRNA coding units have adopted, in the course of evolution, all the possible ways of being transcribed, thus providing a unique paradigm of gene expression flexibility. By focusing on representative fungal, plant and animal genomes, we review here all the documented types of snoRNA gene organizati…
Minimal star-varieties of polynomial growth and bounded colength
2018
Abstract Let V be a variety of associative algebras with involution ⁎ over a field F of characteristic zero. Giambruno and Mishchenko proved in [6] that the ⁎-codimension sequence of V is polynomially bounded if and only if V does not contain the commutative algebra D = F ⊕ F , endowed with the exchange involution, and M , a suitable 4-dimensional subalgebra of the algebra of 4 × 4 upper triangular matrices , endowed with the reflection involution. As a consequence the algebras D and M generate the only varieties of almost polynomial growth. In [20] the authors completely classify all subvarieties and all minimal subvarieties of the varieties var ⁎ ( D ) and var ⁎ ( M ) . In this paper we e…
Polynomial growth and star-varieties
2016
Abstract Let V be a variety of associative algebras with involution over a field F of characteristic zero and let c n ⁎ ( V ) , n = 1 , 2 , … , be its ⁎-codimension sequence. Such a sequence is polynomially bounded if and only if V does not contain the commutative algebra F ⊕ F , endowed with the exchange involution, and M, a suitable 4-dimensional subalgebra of the algebra of 4 × 4 upper triangular matrices. Such algebras generate the only varieties of ⁎-algebras of almost polynomial growth, i.e., varieties of exponential growth such that any proper subvariety is polynomially bounded. In this paper we completely classify all subvarieties of the ⁎-varieties of almost polynomial growth by gi…
Der kontaminierte Hippokrates: Textkritischer Wert und Vorlagen der Handschrift Parisinus gr. 2142.
2014
Il manoscritto Parisinus Graecus 2142 è uno dei più antichi ed importanti tra i cosiddetti codici recenziori della tradizione manoscritta del corpus ippocratico, e si presta particolarmente per la sua natura bipartita e contaminata ad essere riesaminato dal punto di vista del suo valore per l'editore di testi ippocratici. Una tale analisi critica non può prescindere dal problema delle origini delle contaminazioni cui le diverse mani che hanno vergato il Parisinus avrebbero avuto accesso. L'analisi dettagliata delle diverse mani correttrici e del loro apporto alla constitutio del testo di un campione significativo di scritti ippocratici mostra il particolare rilievo del Parisinus, specie del…
Art. 133 (convenzioni internazionali)
2006
Si tratta di un commento all'art. 133 del Codice dei beni culturali e del paesaggio, dedicato al rilievo nel diritto italiano delle convenzioni internazionali in materia. This is a Commentary to Article 133 of the Italian Heritage and Landscape Code.

Who turns to entrepreneurship later in life? - Push and pull in Finnish rural and urban areas
2014
Age is an important factor in entrepreneurship. The paths into entrepreneurship at a later age may be varied. Self-employment in later life may be either a form of partial retirement or a career option. Older individuals may also be pushed into self-employment. The focus of this paper is on the career choices of older individuals and their background motivations in Finland. The purpose is to analyse the factors and motives in terms of the push and pull dichotomy that lead individuals to enter self-employment at older ages in different types of labour markets in Finland, viz., rural and urban areas. Although some studies have focused on transitions to self-employment among older workers, que…
ETAT: Expository Text Analysis Tool.
2002
Qualitative methods that analyze the coherence of expository texts not only are time consuming, but also present challenges in collecting data on coding reliability. We describe software that analyzes expository texts more rapidly and produces a notable level of objectivity. ETAT (Expository Text Analysis Tool) analyzes the coherence of expository texts. ETAT adopts a symbolic representational system, known as conceptual graph structures. ETAT follows three steps: segmentation of a text into nodes, classification of the unidentified nodes, and linking the nodes with relational arcs. ETAT automatically constructs a graph in the form of nodes and their interrelationships, along with various a…
Lua Code: Security Overview and Practical Approaches to Static Analysis
2017
Lua is an interpreted, cross-platform, embeddable, performant and low-footprint language. Lua's popularity is on the rise in the last couple of years. Simple design and efficient usage of resources combined with its performance make it attractive for production web applications even to big organizations such as Wikipedia, CloudFlare and GitHub. In addition to this, Lua is one of the preferred choices for programming embedded and IoT devices. This context allows to assume a large and growing Lua codebase yet to be assessed. This growing Lua codebase could be potentially driving production servers and extremely large number of devices, some perhaps with mission-critical function for example i…
SAP UI5 lietotņu pirmkoda automatizētas pārstrādes rīka izstrāde
2018
Kvalifikācijas darbā tika izstrādāts rīks SAP UI5 lietotņu pirmkoda automatizētai pārveidei, kas veic SAP UI5 JavaScript koda analīzi un aizvieto novecojušās un mazāk efektīvās sinhronās moduļu ielādes metodes ar aktuālajām un tīmekļa kontekstā efektīvākām asinhronajām moduļu ielādes metodēm, kā arī veic koda izmaiņas, kuru nepieciešamība izriet no iepriekšminētās metožu aizvietošanas. Izstrādātā rīka mērķis ir padarīt automātisku, ātru un pabeigtu, bez cilvēciskām kļūdām, šādas pārstrādes procesu tām lietotnēm un projektiem, kuru izstrāde ir aizsākusies pietiekami sen, lai kodu būtu nepieciešams šādi aktualizēt. Rīks tika izstrādāts izmantojot SAP UI5 ietvaru lietotāja saskarnes pusē, Node…
