New Constraints on variations of the fine structure constant from CMB anisotropies (2009)
Menegoni, Eloisa, Galli, Silvia, Bartlett, James, Melchiorri, Alessandro
We demonstrate that recent measurements of Cosmic Microwave Background temperature and polarization anisotropy made by the ACBAR, QUAD and BICEP experiments substantially improve the cosmological...
Galli, Silvia, Melchiorri, Alessandro, Smoot, George F., Zahn, Oliver
We present new constraints on cosmic variations of Newton's gravitational constant by making use of the latest CMB data from WMAP, BOOMERANG, CBI and ACBAR experiments and independent constraints...
A demonstrator for bolometric interferometry (2009)
Ghribi, Adnan, Tartari, Andrea, Galli, Silvia, Piat, Michel, Breelle, Eric, Hamilton, Jean-Christophe, ...
Bolometric Interferometry (BI) is one of the most promising techniques for precise measurements of the Cosmic Microwave Background polarization. In this paper, we present the results of DIBO...
Delayed Recombination and Standard Rulers (2008)
De Bernardis, Francesco, Bean, Rachel, Galli, Silvia, Melchiorri, Alessandro, Silk, Joseph, Verde, Licia
Measurements of Baryonic Acoustic Oscillations in galaxy surveys have been recognized as a powerful tool for constraining dark energy. However, this method relies on the knowledge of the size of the...
Delayed Recombination and Cosmic Parameters (2008)
Galli, Silvia, Bean, Rachel, Melchiorri, Alessandro, Silk, Joseph
Current cosmological constraints from Cosmic Microwave Background (CMB) anisotropies are typically derived assuming a standard recombination scheme, however additional resonance and ionizing...
Il lavoro svolto riguarda lanalisi delle rotte di migrazione post-riproduttiva di 9 femmine di tartaruga liuto (Dermochelys coriacea) nidificanti sulla costa nord-orientale del Sudafrica. Tali rotte...
Changing the Research Patenting Regime: Schumpeterian Explanation (2007)
Starting in the early 1980s, the U.S. patent regime experienced major changes that allowed the patenting of numerous scientific findings lacking in current commercial applications. We assess the...
Privatization of Knowledge: Did the U.S. Get It Right?
Brilliant ideas are key to economic growth. They often emerge from scientific discoveries with no immediate commercial value - so rewards may not be aligned to effort. Should basic research be...
Narrowing the US twin deficits: simulations with a world macroeconometric model
Alberto Bagnai, Silvia Galli, Eleonora Pierucci, Simone Raimondi
In this paper we extend the macroeconometric model developed in Bagnai (2004) by linking it to a submodel for the Japanese economy, and we utilize this extended model to investigate several...
Science-Based R&D in Schumpeterian Growth
Firm success is often associated with the development of better products. Private firms undertake applied R&D seeking market advantage, by capitalizing on the freely accessible results of basic...
Upstream Innovation Protection: Common Law Evolution and the Dynamics of Wage Inequality
What is the most innovation-enhancing level of patent protection for the new ideas generated within the framework of multi-stage sequential innovation? How does increasing early innovation...
Changing the Research Patenting Regime: Schumpeterian Explanation
Starting in the early 1980s, the U.S. patent regime experienced major changes that allowed the patenting of numerous scientific findings lacking in current commercial applications. We assess the...
Patents and Research Tools in a Schumpeterian Growth Model with Sequential Innovation
In the standard quality-ladder growth models, R&D firms undertake independent innovation processes to discover ideas whose value immediately transfers into tradeable applications. Here the standard...
