Brassica tardarae (Brassicaceae), a New Species from a Noteworthy Biotope of South-Western Sicily (Italy)

A new species of Brassica sect. Brassica is described here from Sicily (Italy), which is known to be one of the centers of the diversification of wild taxa of this group. The new species (named Brassica tardarae) is restricted to the carbonate cliffs in the Tardara Gorges between Menfi and Sambuca di Sicilia (Agrigento province), an area with a peculiar geological history and where another strictly endemic species was recently described. The morphological relationships between the new species and other similar taxa are discussed, and an analytical key to the Sicilian taxa belonging to the genus Brassica sect. Brassica is also provided

LHCb Particle Identification Upgrade: Technical Design Report

The LHCb upgrade will take place in the second long shutdown of the LHC, currently scheduled to begin in 2018. The upgrade will enable the experiment to run at luminosities of 2 x 10^33 cm^-2 s^-1 and will read out data at a rate of 40MHz into a exible software-based trigger. All sub-detectors of LHCb will be re-designed to comply with these new operating conditions. This Technical Design Report presents the upgrade plans of the Ring Imaging Cherenkov (RICH) system, the calorimeter system and the muon system, which together provide the particle identication capabilities of the experiment

A contribution to the characterization of Ruppia drepanensis (Ruppiaceae), a key species of threatened Mediterranean wetlands

To elucidate the taxonomic status of Ruppia drepanensis Tineo ex Guss. (Alismatales, Ruppiaceae), we performed morphological analysis and DNA barcoding of historical materials (including the lectotype) and fresh samples (including those from a recently discovered population near the locus classicus in Sicily, Italy). We conclude that R. drepanensis is a separate species, closely related to R. spiralis L. ex Dumort., that occurs in temporary inland waters from the western to central sectors of the Mediterranean region. We also highlight the importance of vouchers and the need to link molecular investigations to field, ecological, and morphological investigations

The artificial retina processor for track reconstruction at the LHC crossing rate

We present results of an R&D study for a specialized processor capable of precisely reconstructing, in pixel detectors, hundreds of charged-particle tracks from high-energy collisions at 40 MHz rate. We apply a highly parallel pattern-recognition algorithm, inspired by studies of the processing of visual images by the brain as it happens in nature, and describe in detail an efficient hardware implementation in high-speed, high-bandwidth FPGA devices. This is the first detailed demonstration of reconstruction of offline-quality tracks at 40 MHz and makes the device suitable for processing Large Hadron Collider events at the full crossing frequency.Comment: 4th draft of WIT proceedings modified according to JINST referee's comments. 10 pages, 6 figures, 2 table

Photon counting with photon number resolution through superconducting nanowires coupled to a multi-channel TDC in FPGA

The paper presents a system for measuring photon statistics and photon timing in the few-photon regime down to the single-photon level. The measurement system is based on superconducting nanowire single photon detectors and a time-to-digital converter implemented into a programmable device. The combination of these devices gives high performance to the system in terms of resolution and adaptability to the actual experimental conditions. As a case of application, we present the measurement of photon statistics for coherent light states. In this measurement, we make use of 8th order single photon correlations to reconstruct with high fidelity the statistics of a coherent state with average photon number up to 4. The processing is performed by means of a tapped-delay-line time-to-digital converter architecture that also hosts an asynchronous-correlated-digital-counter implemented in a field programmable gate array device and specifically designed for performance optimization in multi-channel usage

Behavioral aspects in children's brothers affected by Autism Spectrum Disorders

Introduction: Autistic Spectrum Disorder (ASD) is a permanent and complex disability arising within the first three years of life characterized by a socio-communicative disorder and by fixed interests and repetitive behaviors. The present pilot study aims to evaluate behavioral aspects in a small population of siblings of ASD children. Material and methods: Population: 5 school-aged children (2 males, 3 females) (mean age 9.235 ± 2.041) were enrolled, as siblings of ASD children, and for comparison, 12 healthy (7 males, 5 females) children (average age 9,528 ± 3,351). All subjects underwent evaluation of the behavioral with Child Behavior Checklist (CBCL) scale. Results: The two groups were statistically comparable by age (p = 0.86) and gender distribution (p = 0.87). From the behavioral point of view evaluated with the CBCL scale, siblings of ASD have a higher degree of overall problem (Total problems) compared to control children (p=0.003), in addition they have significantly higher scores in the subscales of behavior examined (Anxious/Depressed, Withdrawn, Somatic Complaints, Social, Thought, Attention, Delinquent, Aggressive) as well as a greater share of disturbances both internalizing (p=0.004) and externalizing (p = 0.007) (Table 1). Conclusions: The present preliminary data confirm the need for a global management of the entire family structure for the correct management of Autistic Disorders
