Charge radii of neon isotopes across the sd neutron shell
2011
We report on the changes in mean square charge radii of unstable neon nuclei relative to the stable Ne-20, based on the measurement of optical isotope shifts. The studies were carried out using collinear laser spectroscopy on a fast beam of neutral neon atoms. High sensitivity on short-lived isotopes was achieved thanks to nonoptical detection based on optical pumping and state-selective collisional ionization, which was complemented by an accurate determination of the beam kinetic energy. The new results provide information on the structural changes in the sequence of neon isotopes all across the neutron sd shell, ranging from the proton drip line nucleus and halo candidate Ne-17 up to the…
Lower Rydberg series of methane: a combined coupled cluster linear response and molecular quantum defect orbital calculation.
2006
Vertical excitation energies as well as related absolute photoabsorption oscillator strength data are very scarce in the literature for methane. In this study, we have characterized the three existing series of low-lying Rydberg states of CH4 by computing coupled cluster linear response (CCLR) vertical excitation energies together with oscillator strengths in the molecular-adapted quantum defect orbital formalism from a distorted Cs geometry selected on the basis of outer valence green function calculations. The present work provides a wide range of data of excitation energies and absolute oscillator strengths which correspond to the Rydberg series converging to the three lower ionization p…
Causal complexity of new product development processes : a mechanism-based approach
2018
The outcomes of new product development (NPD) processes are dependent on the interplay of several interdependent activities. One product development activity can be dependent on the presence or absence of other activities, different kinds of NDP processes may lead to the same outcome, and specific kinds of activities may have a positive effect in one process but no effect in other processes. However, we currently lack means to examine and explain this causal complexity inherent in NPD processes. To address this issue, we introduce mechanism-based approach as a way to capture conjunctural and equifinal causal relations. We build this approach on the philosophical literature on mechanism-base…

Configurations of the Interactive Use of Environmental Management Control
2013
This paper explores the use of interactive environmental management control. In order to do this, a theoretical model is designed drawing on the framework of Simons (1995) and instrumental stakeholder theory. This model defines three dimensions of interactive control: forms of interactivity (vertical, horizontal, external), frequencies of interactivity (high, medium, low) and decision levels (strategic, tactical, operational). Four typical configurations emerge from application of the model to empirical data from ten case studies: eco-designers, eco-institutionals, eco-managers and eco-educators. These configurations show the diverse roles of interactive environmental management control in …
Autobiografie interrotte. Plasticità distruttrice, riconfigurazioni estetiche e identità accidentali
2023
Che relazione esiste tra il corpo di ciascun individuo e la sua identità individuale? La nostra identità rimane immutata nel tempo, permettendoci di narrare un’autobiografia lineare, o possono sopraggiungere eventi accidentali che contribuiscono a modificarla radicalmente, dando vita a una nuova versione di noi stessi, a una nuova storia? In questo articolo ci proponiamo di rispondere a tali domande partendo dalle riflessioni della pensatrice francese Catherine Malabou. Affronteremo il problema della costruzione e della decostruzione dell'identità individuale alla luce dell'ontologia dell'incidente, analizzando il concetto di plasticità negativa e cercando di delineare come un evento accide…
Changes in the Intra-Metropolitan Location of Producer Services in Ile-de-France (1978-1997) : do information technologies promote a more dispersed s…
2003
Because of their intensive need for face-to-face contacts, producer services have, historically, been found at the core o f CBDs. However, it has been suggested that advances in information technologies could lead to the erosion o f the CBD’s economic base, rendering face-to-face contacts obsolete and enabling producer services to suburbanize. Although a considerable amount o f empirical work has been done on the suburbanization o f these activities in North-America, the same is not true of France. In this paper, we adopt an original methodology to study the role played by face-to-face contacts in the spatial distribution of producer services in the Ile-de-France region between 1978 and 199…
On a Continuous Sárközy-Type Problem
2022
Abstract We prove that there exists a constant $\epsilon> 0$ with the following property: if $K \subset {\mathbb {R}}^2$ is a compact set that contains no pair of the form $\{x, x + (z, z^{2})\}$ for $z \neq 0$, then $\dim _{\textrm {H}} K \leq 2 - \epsilon $.
Efficient Design of Waveguide Manifold Multiplexers Based on Low-Order EM Distributed Models
2015
In this paper, a new systematic technique to design manifold-coupled multiplexers in waveguide technology is proposed. The new technique uses generalized low-order electromagnetic (EM) distributed models, which constitute a half-way point between the fast, but imprecise, analytical models, and the more accurate, but costly, full-wave EM models. The method can be applied to contiguous and noncontiguous channel multiplexers, in both E-plane or H-plane configurations. This paper covers the complete design procedure for manifold multiplexers, starting from the required specifications and finishing with the physical dimensions. After explaining the general design technique for multiplexers with …
Structure of longitudinal chromomagnetic fields in high energy collisions
2014
We compute expectation values of spatial Wilson loops in the forward light cone of high-energy collisions. We consider ensembles of gauge field configurations generated from a classical Gaussian effective action as well as solutions of high-energy renormalization group evolution with fixed and running coupling. The initial fields correspond to a color field condensate exhibiting domain-like structure over distance scales of order the saturation scale. At later times universal scaling emerges at large distances for all ensembles, with a nontrivial critical exponent. Finally, we compare the results for the Wilson loop to the two-point correlator of magnetic fields.
