Two new apricot varieties

2010

Nella and Dora are apricot seedlings recently selected by R. Chiappetta in Sicily. Their vegetative, floreal, agronomic and fruit-quality characteristics were checked for three years (2003 - 2005) in Partinico (Palermo coast area), under mild winter and spring temperatures, in comparison with Tyrinthos variety. Nella and Dora have an upright tree habit and are self-compatible. Blooming started a week earlier in Nella and Tyrinthos (end of February) and concluded in the second part of March in all varieties. Fruit set was satisfactory in all cultivars. Crop was harvested from May 25th to 30th in Dora, May 24th to 30th in Nella and May 24th to 28th in Tyrinthos. Fruit weight, as a three years…

Systematic review and critical appraisal of Childhood Trauma Questionnaire - Short Form (CTQ-SF).

2021

Abstract Background Child maltreatment is a complex and multidimensional construct that encompasses a great number of risk factors. The Childhood Trauma Questionnaire — Short Form, one of the most widely used and validated instruments to assess childhood maltreatment in the past ten years, is a retrospective instrument that assesses several types of childhood abuse and maltreatment which is divided into five dimensions. Objective The objectives of this systematic review are to critically appraise, compare, and summarize the methodological quality and psychometric properties of published research articles validating the Childhood Trauma Questionnaire — Short Form utilizing the COSMIN checkli…

Dyadic Norm Besov-Type Spaces as Trace Spaces on Regular Trees

2019

In this paper, we study function spaces defined via dyadic energies on the boundaries of regular trees. We show that correct choices of dyadic energies result in Besov-type spaces that are trace spaces of (weighted) first order Sobolev spaces.

[Clinical guidelines for the management of gastrointestinal stromal tumors]

2006

Treatment of gastrointestinal stromal tumors (GIST) has been revolutioned by the recently discovered molecular mechanism responsible for the oncogenesis of this disease. In addition, due to the rapid progress at molecular and clinical level observed in the last few years, there is a need to review the current state of the art in order to delineate appropriate guidelines for the optimal management of these tumors. A panel of experts from several specialities, including medical oncology, surgery, pathology, molecular biology and imaging, were invited to participate in a meeting to present and discuss a number of pre-selected questions, and to achieve a consensus according to the categories of…

Trace Operators on Regular Trees

2020

Abstract We consider different notions of boundary traces for functions in Sobolev spaces defined on regular trees and show that the almost everywhere existence of these traces is independent of the chosen definition of a trace.

Admissibility versus Ap-Conditions on Regular Trees

2020

We show that the combination of doubling and (1, p)-Poincaré inequality is equivalent to a version of the Ap-condition on rooted K-ary trees. peerReviewed

Gray coding cubic planar maps

2016

International audience; The idea of (combinatorial) Gray codes is to list objects in question in such a way that two successive objects differ in some pre-specified small way. In this paper, we utilize beta-description trees to cyclicly Gray code three classes of cubic planar maps, namely, bicubic planar maps, 3-connected cubic planar maps, and cubic non-separable planar maps.

QSAR models for tyrosinase inhibitory activity description applying modern statistical classification techniques: A comparative study

2010

Abstract Cluster analysis (CA), Linear and Quadratic Discriminant Analysis (L(Q)DA), Binary Logistic Regression (BLR) and Classification Tree (CT) are applied on two datasets for description of tyrosinase inhibitory activity from molecular structures. The first set included 701 tyrosinase inhibitors (TI) that are used for performance of inhibitory and non-inhibitory activity and the second one is for potency estimation of active compounds. 2D TOMOCOMD-CARDD atom-based quadratic indices are computed as molecular descriptors. CA is used to “rational” design of training (TS) and prediction set (PS) but it shows of not being adequate as classification technique. On the first data, the overall a…
