Reproducción social y reproducción biológica en la Italia del fin de milenio

En el contexto de crisis económica, debilitamiento del consenso, la preocupación por el cuerpo femenino y nuevas formas de reproducción toma una especial relevancia en Italia en términos éticos y políticos.In the context of the actual economic crisis and lack of consensus, great concern exist in woman's body and new forms of reproduction in ethical and political terms

The hippo signaling pathway: implications for heart regeneration and disease

Control of cell number and organ size is critical for appropriate development and tissue homeostasis. Studies in both Drosophila and mammals have established the Hippo signaling pathway as an important modulator of organ size and tumorigenesis. Upon activation, this kinase cascade modulates gene expression through the phosphorylation and inhibition of transcription co-activators that are involved in cell proliferation, differentiation, growth and apoptosis. Hippo signaling serves to limit organ size and suppress malignancies, and has been implicated in tissue regeneration following injury. These outcomes highlight the important role that Hippo signaling plays in regulating both physiologic and pathologic processes. In this review, an overview of the signaling pathway will be discussed as well as recent work that has investigated its role in cardiac development, regeneration and disease.

Narcisistici patologici e pericolosità socio-economica

Il saggio intende fornire una personale rilettura degli studi sul narcisismo patologico in chiave socio-economica, ovvero avanzare l’ipotesi per cui i soggetti affetti dal suddetto disturbo di personalità (disturbo narcisistico della personalità “DNP”), possano poi essere più portati/tendenti a compiere atti di criminalità economica. L’analisi si basa sull’assunto empirico che il criminale economico gioca lo stesso ruolo nei confronti dell’organizzazione sociale che il narcisista assume nei confronti della vittima all’interno di una relazione. In entrambi i casi, tanto la societas che la persona sono “vittime invisibili” ed inconsapevoli del gioco al massacro che il disturbato sta intentando loro, impostato sulle loro debolezze. A tratti, paradossalmente, ne diventano anche complici, osannandone ed esaltandone le caratteristiche, e contribuendo inconsapevolmente a creare un “grande bluff” attorno alla loro figura. D’altra parte l’organizzazione socio-economica pubblica ha bisogno ed incoraggia la creazione di realtà imprenditoriali spregiudicate, dedite solo agli introiti, non capendo che però poi, alla fine, se fomenta questi valori all’eccesso, i danni che ne derivano sono incalcolabili, non sono per le singole persone ma per l’intera struttura socio-economica di base

Smart Specialisation Strategies for Supporting Europe 2020 Vision. Looking at the American Experience: the Case of the Boston Area

These reflections aim to highlight the crucial challenge that European Regions are called to face applying the ‘Research and Innovation Strategies for Smart Specialization’ policy for pursuing the virtuous implementation of EU Cohesion Policy and ‘Europe 2020’ Agenda. The original cultural style of the ‘US Smart Specialization model’, supported by the ‘cluster theory’ and the ‘innovation paradigm’, represents a significant lesson in Boston area

Collision and fusion of counterpropagating micron-sized optical beams in non-uniformly biased photorefractive crystals

We theoretically investigate collision of optical beams travelling in opposite directions through a centrosymmetric photorefractive crystal biased by a spatially non-uniform voltage. We analytically predict the fusion of counterpropagating solitons in conditions in which the applied voltage is rapidly modulated along the propagation axis, so that self-bending is suppressed by the "restoring symmetry" mechanism. Moreover, when the applied voltage is slowly modulated, we predict that the modified self-bending allows conditions in which the two beams fuse together, forming a curved light-channel splice.Comment: 12 page

Photonic polarization gears for ultra-sensitive angular measurements

Quantum metrology bears a great promise in enhancing measurement precision, but is unlikely to become practical in the near future. Its concepts can nevertheless inspire classical or hybrid methods of immediate value. Here, we demonstrate NOON-like photonic states of m quanta of angular momentum up to m=100, in a setup that acts as a "photonic gear", converting, for each photon, a mechanical rotation of an angle {\theta} into an amplified rotation of the optical polarization by m{\theta}, corresponding to a "super-resolving" Malus' law. We show that this effect leads to single-photon angular measurements with the same precision of polarization-only quantum strategies with m photons, but robust to photon losses. Moreover, we combine the gear effect with the quantum enhancement due to entanglement, thus exploiting the advantages of both approaches. The high "gear ratio" m boosts the current state-of-the-art of optical non-contact angular measurements by almost two orders of magnitude.Comment: 10 pages, 4 figures, + supplementary information (10 pages, 3 figures

Secure information transport by transverse localization of light

A single-photon beating with itself can produce even the most elaborate optical fringe pattern. However, the large amount of information enclosed in such a pattern is typically inaccessible, since the complete distribution can be visualized only after many detections. In fact this limitation is only true for delocalized patterns. Here we demonstrate how reconfigurable localized optical patterns allow to encode up to 6 bits of information in disorder-induced high transmission channels, even using a small number of photon counts. We developed a quantum key distribution scheme for fiber communication in which high information capacity is achieved through position and momentum complementarity
