Abstract

A novel analytical Gaussian approximation is developed for the evaluation of the distortion spectrum introduced by a nonlinear amplifier. This method allows to consider high-order distortion contributions when the device is driven by a broadband signal with Gaussian amplitude distribution. The results are applied to a ninth-order power series model based on well known single-tone and two-tone analysis parameters. The cascade of two or more amplifiers is investigated as weli providing a complete set of tools for the early system specification of broadband transceivers. Simulations shows excellent agreement even for high input power levels, when former third-order and fifth-order approximations fail to yield accurate predictions. Index Terms--Amplifier nonlinear characteristics, gain compression, nonlinear distortion, spectral analysis.

26. Distribution range and ecological niche of Primula marginata Curtis (Primulaceae)

Abstract

The distribution range of Primula marginata Curtis (Primulaceae) has never been fully characterized. In the present study, authors did a revision of the distribution range using herbaria material, database records and in situ populations' check-up. P. marginata was confirmed extending from Cottian to Maritime and Ligurian Alps, with few outlier occurrences in the northern Apennines. The localities previously reported from northern Piedmont (Val d'Ossola) were not confirmed. Maximum entropy model (Maxent) was used to simulate the potential distribution of P. marginata under current climate conditions. According to the distribution modelling performed, the species prefers rocky calcareous habitats mainly at high elevations, with abundant precipitation, but low moisture retention at soil level and marked temperature range between winter and summer seasons. The potential distribution area drawn by Maxent seemed to describe P. marginata at its maximum extension, and any future climate changes might cause limitations for the survival of the species.

Abstract

Sub-harmonic injection locking is employed to generate the fast-hopping carriers required in UWB systems for WiMedia . A very small area 90-nm CMOS prototype synthesizes the frequencies of band group #6 with a hop time shorter than 4 ns . It occupies 0.074 mm2 and draws 30 mA from a 1.2 V supply. Phase noise at 8.71 GHz is - 112 dBc/Hz at 1 MHz offset. The design is supported by a thorough analysis that emphasizes the tradeoffs in the parameters of the proposed system. [ABSTRACT FROM AUTHOR]

45. The Silky Shark, Carcharhinus falciformis BIBRON, 1841), in the Pliocene of Cava Serredi (Fine Basin, Italy)

Author

Carnevale, Giorgio, Marsili, Stefano, Caputo, and Egisti, Lorenzo

Abstract

An isolated tooth of the Silky Shark, Carcharhinus falciformis, is described from the Early Pliocene of Cava Serredi in the Fine Basin, Tuscany. The specimen is interpreted as an upper lateral-posterior tooth and is characterized by a straight mesial cutting edge with a marked gap in the serrations at the level of the angular notch. The thermophilous character of this shark species provides new evidence of the warm climatic affinities that the Mediterranean had during the lower Zanclean. From a paleoenvironmental point of view the occurrence of Carcharhinus falciformis is consistent with the data derived from microfossil assemblage analyses, and appears to be indicative of a depositional setting close to the edge of the continental shelf.

Abstract

We conducted a GIS spatial analysis with the aim of providing the first quantitative large-scale overview of the distribution patterns of 1536 type localities ( loci classici ) of 1216 Italian endemic vascular plants and their relationship with a set of descriptive variables. Whereas some variables were used to model the presence-absence distribution patterns of the type localities for the whole set of endemics as well as for the subset of narrow endemics, others (e.g., presence inside or outside protected areas and Italian Important Plant Areas) were considered with the purpose of assessing potential assets or risks for conservation. The largest number of type localities was found within the Mediterranean biogeographic region (1134), followed by the Alpine region (306) and Continental region (96). A total of 670 locations are located on islands, whereas 866 are located on the Italian mainland (139 and 124 in the case of narrow endemics, respectively). A large number of type localities are located in mountainous areas and along the coastline, which can be seen as a potential risk for conservation. On the contrary, we detected a positive correlation with the distance from roads, which might be considered to be an asset. Importantly, 1030 type localities fall inside protected areas, whereas 506 localities fall outside protected areas, with 259 of these unprotected localities on islands. We propose considering the results of the analysis of the distribution of type localities of Italian endemics to be a strategic tool for conservation planning and resource management. Application of plant micro-reserves and integration of diverse legislation tools are suggested to strengthen efforts and increase conservation success.
