ELDAR, a new method to identify AGN in multi-filter surveys: the ALHAMBRA test case

2017

We present ELDAR, a new method that exploits the potential of medium- and narrow-band filter surveys to securely identify active galactic nuclei (AGN) and determine their redshifts. Our methodology improves on traditional approaches by looking for AGN emission lines expected to be identified against the continuum, thanks to the width of the filters. To assess its performance, we apply ELDAR to the data of the ALHAMBRA (Advance Large Homogeneous Area Medium Band Redshift Astronomical) survey, which covered an effective area of 2.38 deg2 with 20 contiguous medium-band optical filters down to F814W ≃ 24.5. Using two different configurations of  ELDAR in which we require the detection of at lea…

Forearc carbon sink reduces long-term volatile recycling into the mantle

2019

Carbon and other volatiles in the form of gases, fluids or mineral phases are transported from Earth's surface into the mantle at convergent margins, where the oceanic crust subducts beneath the continental crust. The efficiency of this transfer has profound implications for the nature and scale of geochemical heterogeneities in Earth's deep mantle and shallow crustal reservoirs, as well as Earth's oxidation state. However, the proportions of volatiles released from the forearc and backarc are not well constrained compared to fluxes from the volcanic arc front. Here we use helium and carbon isotope data from deeply sourced springs along two cross-arc transects to show that about 91 per cent…

Place-based policy in southern Italy: evidence from a dose-response approach

2021

This paper evaluates the effectiveness at a territorial level of a place-based policy for southern Italy, that is, territorial integrated projects (TIPs). We combine classical counterfactual designs and the construction of a dose–response function to assess the impact of the infrastructural interventions on the municipalities involved in a target region (Sicily). The results are robust enough to show policy effectiveness on both the number of workers and the number of plants. In the latter case, we also identify a significant and increasing dose–response function highlighting the positive relationship between funding intensity and the growth of plants.

A simple scheme for the direct calculation of ionization potentials with coupled-cluster theory that exploits established excitation energy methods

1999

Vertical ionization potentials can be obtained from existing computer programs for the high-level treatment of excited states by simply including a continuum orbital in the basis set. Exploiting this feature easily allows final state energies for ionized states to be calculated at several previously untested levels of theory that go beyond the equation-of-motion coupled-cluster singles and doubles model. Values obtained for N2, CO, and F2 with the most theoretically complete approximations studied here (those based on the CCSDT-3 and CC3 parametrizations of the neutral ground state) are in excellent agreement with experiment when a large basis set is used.

Discrete Time Versus Continuous Time Approach to the Autoimmune Response

1989

A discrete time model for the immune regulation recently proposed by Weisbuch and Atlan is extended to continuous coupling coefficients as well as to continuous concentration rates in continuous time. It is shown that depending on the choice of the network parameters typical immune responses can be observed.

Autonomie e controlli della Corte dei conti nel quadro dei principi costituzionali e dei vincoli sovranazionali in materia economico-finanziaria

2022

Una riflessione dei controlli sulle autonomie territoriali intestati alla Corte dei conti non può prescindere dal loro inquadramento costituzionale. L’A. prospetta una ricostruzione del controllo come espressione di una funzione neutra e imparziale che deve riposare su precisi parametri costituzionali che ne legittimano l’adozione e di cui va resa una stretta interpretazione: il controllo sulle Autonomie territoriali deve così essere necessariamente una attività tale da avvicinarla a quella giurisdizionale piuttosto che amministrativa. È in tale chiave che deve essere inteso il rapporto fra ausiliarietà di cui all’art. 100 Cost. e controlli sui bilanci ed i rendiconti. L’evoluzione del quad…

Female–female attraction influences nest establishment in the digger wasp Stizus continuus (Hymenoptera: Crabronidae)

2008

Although digger wasps are good models for the study of nest site selection, the behaviour of females in relation to time of nest establishment has rarely been considered despite this being the key to discrimination between substrate availability-based and a female attraction-based selection. We carried out a study on nest establishment by the digger wasp Stizus continuus (Klug), giving to all nests dug by the wasps both spatial (nearest neighbour distance to nests, proximity of vegetation, soil hardness) and temporal (day of excavation) attributes. Stizus continuus females dug more nests under bush edges, where the soil was much softer. There was no tendency for females to maximize distance…

Age and tectonic setting of Late Archean greenstone-gneiss terrain in Henan Province, China, as revealed by single-grain zircon dating

1988

The authors report precise U-Pb zircon ages for single grains of a metarhyodacite from the Late Archean Dengfeng greenstone belt in Henan Province, China, near the southern margin of the North China craton. Most grains belong to an igneous population whose U-Pb isotopic systematics define a straight line intersecting concordia at 2512 +/- 12 Ma, and this is interpreted as the time of crystallization of the original greenstone volcanics. Several grains are distinctly older, between 2576 +/- 9 and 2945 +/- 44 Ma, and the authors interpret the older grains as xenocrysts of pre-greenstone continental crust that provide evidence for crustal derivation or crustal contamination of the original rhy…
