Search for neutral MSSM Higgs bosons at LEP

2006

The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for the neutral Higgs bosons which are predicted by the Minimal Supersymmetric Standard Model (MSSM). The data of the four collaborations are statistically combined and examined for their consistency with the background hypothesis and with a possible Higgs boson signal. The combined LEP data show no significant excess of events which would indicate the production of Higgs bosons. The search results are used to set upper bounds on the cross-sections of various Higgs-like event topologies. The results are interpreted within the MSSM in a number of "benchmark" models, including CP-conserving and CP-violating scenarios. Thes…

Acacia cyclops A. Cunn. ex G. Don (Leguminosae) in Italy: first cases of naturalization

2012

The first two cases of naturalization of Acacia cyclops are reported for Italy. Young trees were observed growing in the wild some 15 years ago on Linosa (Pelagie Islands, Strait of Sicily). A decade later, this alien plant should no longer be considered as a casual, since a very intensive process of self-sown regeneration has been observed in some plantations on Lampedusa, the major island of the same Archipelago. The available literature suggests the need for careful monitoring of the ongoing invasion process, as A. cyclops has already shown a very invasive behaviour elsewhere within Mediterranean-type biomes due to its ability to withstand high environmental stresses. As migrating birds …

El registro material del colmenar ibérico de la Fonteta Ràquia (Riba-Roja, València)

2016

La excavación arqueológica en 2008 del yacimiento de la Fonteta Ràquia (Riba-Roja del Túria, València) permitió documentar un pequeño asentamiento rural de la Edetania, territorio de la antigua ciudad ibérica de Edeta / Tossal de Sant Miquel (Llíria, València). El núcleo estuvo ocupado entre finales del s. V a.C. y finales del III / comienzos del II a.C. Destaca, por encima de todo, por una gran especialización en apicultura, tal y como demuestra el hallazgo de miles de fragmentos de aproximadamente 200 colmenas cerámicas, superando con creces los registros precedentes de este tipo de actividad en Iberia y el Mediterráneo en general. The archaeological excavation of the site in Fonteta Ràqu…

Emporion: un exceptionnel gros module postarchaïque à la tête de Silène / chouette dans carré creux

2017

espanolEntre las monedas «pesadas» atribuidas a la fase arcaica de Emporion, que publicamos en el ano 2013, se encontraba una pieza con cabeza de Sileno de frente en anverso y cuadrado incuso en el reverso. Este ejemplar fue atribuido al grupo de emisiones de la fase arcaica debido a que su elevado peso se correspondia con los nominales de la fase A. No obstante, como consecuencia del estudio de un grupo inedito de obolos post-arcaicos emporitanos, que muestra un mochuelo rodeado de letras griegas dentro de un cuadrado incuso, ahora proponemos relacionar ambos tipos monetarios. Para ello nos basamos en la identificacion de un mochuelo en el interior del cuadrado incuso de nuestra moneda, co…

Marks and Epigraphs on Iberian Amphorae. II

2015

Se presenta la segunda parte del repertorio de marcas y epígrafes sobre ánforas ibéricas, con la intención de completar un fenómeno heredero del mundo púnico. Se pretende ir acotando el/los posible/s significado/s de tales marcas, su distribución territorial y su marco cronológico. Las marcas incisas son, en esta ocasión, más numerosas que las impresas y se ha detectado una nueva técnica postcocción (con pintura y carbón) restringida al noreste peninsular. This paper is the second part of the repertoire of marks and epigraphs on Iberian amphorae. The goal is to complete this work, which is related to the Punic world, and know the possible meanings of such marks, their geographical distribut…

Design at the root of biophilia. Imitation. Nature

2021

According to the current state of research on the phenomenon of biophilia, the positive influence of nature's elements on humans has long been widely understood. Since the negative impact of urbanised areas on quality of life was noticed, human-friendly architecture has been redefined, where the physical and mental well-being of people using buildings, remains highly dependent on their contact with the environment. Selected examples of existing buildings analyzed two different approaches to contemporary biophilic architecture; one where nature is the pedestal of the whole building and one where the interpretation of nature translates into technological, engineering or structural solutions. …

Feasibility of hyperspectral vegetation indices for the detection of chlorophyll concentration in three high Arctic plants: Salix polaris, Bistorta v…

2018

Remote sensing, which is based on a reflected electromagnetic spectrum, offers a wide range of research methods. It allows for the identification of plant properties, e.g., chlorophyll, but a registered signal not only comes from green parts but also from dry shoots, soil, and other objects located next to the plants. It is, thus, important to identify the most applicable remote-acquired indices for chlorophyll detection in polar regions, which play a primary role in global monitoring systems but consist of areas with high and low accessibility. This study focuses on an analysis of in situ-acquired hyperspectral properties, which was verified by simultaneously measuring the chlorophyll conc…

Morphological and molecular characterization of three new parastenocarididae (Copepoda: Harpacticoida) from caves in Southern Italy

2020

We describe three new parastenocaridid: Cottarellicaris sanctiangeli Bruno & Cottarelli sp. nov., Stammericaris vincentimariae Bruno & Cottarelli sp. nov. and Proserpinicars specincola Bruno & Cottarelli sp. nov., collected in the pools of five different caves located in Calabria (Southern Italy). We conducted a phylogenetic analysis based on the mitochondrial COI and ribosomal 18S sequences of C. sanctiangeli sp. nov. and S. vincentimariae sp. nov., and of four more species of Stammericaris and one Proserpinicaris available from literature. Based on the molecular study, the specimens of C. sanctiangeli sp. nov. are clearly separated from the species belonging to the closely-rel…

DeepEva: A deep neural network architecture for assessing sentence complexity in Italian and English languages

2021

Abstract Automatic Text Complexity Evaluation (ATE) is a research field that aims at creating new methodologies to make autonomous the process of the text complexity evaluation, that is the study of the text-linguistic features (e.g., lexical, syntactical, morphological) to measure the grade of comprehensibility of a text. ATE can affect positively several different contexts such as Finance, Health, and Education. Moreover, it can support the research on Automatic Text Simplification (ATS), a research area that deals with the study of new methods for transforming a text by changing its lexicon and structure to meet specific reader needs. In this paper, we illustrate an ATE approach named De…
