4-th International Conference on Unsolved Problems of Noise and Fluctuations in Physics, Biology anf High Technology, (UPoN - 2005)
No full textThe previous editions of this conference were taken in Szeged (Hungary), Adelaide (Australia) and Washington, DC (USA). The 4-th edition with chairman L. Reggiani, Co-chairman C. Pennetta and local organizing committe C. Pennetta, E. Alfinito, M. Leuzzi,
V. Akimov, M. Rosini, was taken in Gallipoli (Lecce), the 6-10 June 2005 and it had 110 partecipants coming from 4 continents and 27 countries.
Since its first edition held in 1996 in Szeged, the aim of the UPoN conference is to provide a forum for researchers working on noise and fluctuations, where they can present and discuss their scientific problems which do resist solutions. These unsolved problems needs a more thorough, more open-minded, and less
biased refereeing process than the presentation of solved problems typical in the publications of the standard literature. The conference tradition dictates that to be accepted each proposal (invited, contributed oral and poster papers) has to be reviewed using double-blind refereeing process by appropriate members
of the Scientific Committee. The conference will focus on noise and fluctuations at the nanometric scale-length in electron-devices, biomaterials and mesoscopic systems

Fluctuations of complex networks: electrical properties of single protein nanodevices
No full textWe present for the first time a complex network approach to the study of the electrical properties of single protein devices. In particular, we consider an electronic nanobiosensor based on a G-protein coupled receptor. By adopting a coarse grain description, the protein is modeled as a complex network of elementary impedances. The positions of the alpha-carbon atoms of each amino acid are taken as the nodes of the network. The amino
acids are assumed to interact electrically among them. Consequently, a link is drawn between any pair of nodes
neighboring in space within a given distance and an elementary impedance is associated with each link. The value of this impedance can be related to the physical and chemical properties of the amino acid pair and to their relative distance. Accordingly, the conformational changes of the receptor induced by the capture of the ligand, are translated into a variation of its electrical properties. Stochastic fluctuations in the value of the elementary impedances of the network, which mimic different physical effects, have also been considered. Preliminary results
concerning the impedance spectrum of the network and its fluctuations are presented and discussed for different values of the model parameters
Ceramic PPC technology and performance
No full textMass production technology for PPCs (Parallel Plate Chambers) is described. This technology provides a precise manufacture of chamber components and a high uniformity of chamber properties. Only radiation hard materials were used. Results on the chamber uniformity, the detection efficiency and the timing properties of PPCs are presented. © 1994

A complex network model for the study of electrical properties of G-coupled protein receptors

Ultrafast control of light emission from a quantum-well semiconductor microcavity using picosecond strain pulses
No full textA picosecond strain wave packet of subterahertz acoustic phonons is generated in a metal film by optical excitation with a femtosecond laser pulse and injected into a quantum well containing a GaAs-based planar microcavity in the strong-coupling regime. The strain pulse induces a dynamical energy shift of the quantum-well exciton resonance. This results in an ultrafast modulation of the photoluminescence spectrum from the lower polariton branch
