Blends of Semiflexible Polymers: Interplay of Nematic Order and Phase Separation
2021
Mixtures of semiflexible polymers with a mismatch in either their persistence lengths or their contour lengths are studied by Density Functional Theory and Molecular Dynamics simulation. Considering lyotropic solutions under good solvent conditions, the mole fraction and pressure is systematically varied for several cases of bending stiffness κ (the normalized persistence length) and chain length N. For binary mixtures with different chain length (i.e., NA=16, NB=32 or 64) but the same stiffness, isotropic-nematic phase coexistence is studied. For mixtures with the same chain length (N=32) and large stiffness disparity (κB/κA=4.9 to 8), both isotropic-nematic and nematic-nematic unmixing oc…

Between Self-Organizing and Accelerating Networks: Untangling the multilevel of strategic networks
2010
This paper aims to detect the crucial determinants and processes that shape the emergence and evolution of interfirm network cognitive morphology. We pinpoint three relatively distinct but coexistent levels which define the fundamental structure of the network: the microsystemic (or the single firm) level; the mesosystemic (or the groups of firms within the network) level; and the macrosystemic (or the overarching network) level. Then, we integrate the complex system perspective (Morin, 1977; Prigogine and Stengers, 1984; Anderson, 1999) applied to networks with studies regarding theoretical models that elucidate network structuring and dynamics cultivated in the new “science of networks” (…
Exploring cell biodiversity - Neutron scattering investigation of water diffusion in complex system
2015
Scientists from biophysics, biology and medicine fields are interested in exploring and characterizing topologically cerebral tissue in order to diagnostic different diseases which affect brain in many patients [1-3]. One of the most diffuse diagnostic techniques is dMRI (diffusion magnetic resonance imaging) which extracts information about heterogeneity and asymmetries in brain tissue studying water diffusion dynamics (~80% mass constituent of tissues). The experimental limit of this technique is related to the acquisition time, TA, of the order of milliseconds. Water molecules diffuse within micrometre distance using TA as diffuse time (Eistein equation D~2TA). Cells have micrometric siz…

ENABLING LOCAL GOVERNMENTS TO DESIGN AND IMPLEMENT ANTI-CORRUPTION STRATEGIES THROUGH DYNAMIC PERFORMANCE MANAGEMENT AND GOVERNANCE. A CASE-STUDY OF …
2021
Lo scopo principale di questa ricerca è quello di inquadrare le possibili relazioni causali fra corruzione negli approvvigionamenti pubblici e performance delle amministrazioni locali. A tal fine, viene adottato un disegno di ricerca che integra dinamicamente metodi quantitativi e qualitativi in ogni fase del processo di studio. Gli approcci Dynamic Performance Management (DPM) e Governance (DPG), supportati da interviste approfondite non-strutturate, modellazioni formali e simulazioni quantitative, sono qui adottati per analizzare un caso di studio rappresentativo di un piccolo comune italiano in cui si sono verificati alcuni episodi di corruzione nelle attività di approvvigionamento nei p…
