The Botanical Record of Archaeobotany Italian Network - BRAIN: a cooperative network, database and website

The BRAIN (Botanical Records of Archaeobotany Italian Network) database and network was developed by the cooperation of archaeobotanists working on Italian archaeological sites. Examples of recent research including pollen or other plant remains in analytical and synthetic papers are reported as an exemplar reference list. This paper retraces the main steps of the creation of BRAIN, from the scientific need for the first research cooperation to the website which has a free online access since 2015

A study of multi-jet events at the CERN I3p collider and a search for double patton scattering UA2 Collaboration Bern-Cambridge-CERN-Dortmund-Heidelberg-Melbourne-Milano-Orsay (LAL)-Pavia- Perugia-Pisa-Saclay (CEN)

A study of events containing at least four high transverse momentum jets and a search for double parton scattering (DPS) have been performed using data collected with the UA2 detector at the CERN lbp Collider (x/s= 630 GeV). The results are in good agreement with leading order QCD calculations. A value of at~Ps < 0.82 nb at 95% confidence level (CL) is obtained for the DPS cross section

40GHz Frequency Tripler with High Fundamental and Harmonics Rejection in 55nm SiGe-BiCMOS

This paper presents a novel frequency tripler circuit topology which yields a remarkable improvement on the suppression of the driving signal frequency at the output,compared to conventional designs exploiting transistors in class-C. The active core of the circuit approximates the transfer characteristic of a third-order polynomial that ideally produces only a third-harmonic of the input signal. Implemented in a 55nm SiGe-BiCMOS technology and consuming 13.6mA from 1.7V,the tripler demonstrates ~40dB suppression of the input signal and its 5th harmonic over 16% factional bandwidth and robustness to power variation of the driving signal over a 15dB range

Accounting and the Papal States: The influence of the Pro commissa

The aim of this article is to explore the role played by accounting in the building of the early modern Papal States. In particular, the study shows how the control and accountability system set up by the Pro commissa Bull (15 August 1592) allowed the Pope to concentrate and centralize political power, fostering the shift of the Papal States towards the configuration of an absolute state which can be considered the first major institutional embodiment of the modern state in the early modern period. Besides contributing to the literature on accounting and state building, this research also provides insights into the role of accounting in religious institutions. The analysis, in fact, is carried out in one of the most important religious institutions in history. Moreover, the fact that the Pope was both the political and the religious head of the Papal States allows the inference that this peculiar “dual role” could have affected the setting up of the abovementioned control and accountability system

Performance of a liquid argon preshower detector integrated with an accordion calorimeter

A prototype liquid argon preshower detector with a strip granularity of 2.5 mm has been tested at the CERN SPS in front of a liquid argon Accordion calorimeter. For charged tracks a signal-to-noise ratio of 9.4 and a space resolution of 340 mum were measured; the rejection power against overlapping photons produced in the decay of 50 GeV pi0's is larger than 3; the precision on the electromagnetic shower direction, determined together with the calorimeter, is better than 7 mrad above 40 GeV; the calorimeter performance behind the preshower (approximately 4X0) is fully preserved. These results make such a detector attractive for future operation at the CERN Large Hadron Collider
