Parlando di citazioni e di altre cose
No full textSi anticipano qui alcuni interventi del IV Seminario di Bertinoro svoltosi il 17 ottobre 2008
sul tema Tecnica e politica delle citazioni: l’Introduzione di Franco Carinci, nonchè la
relazione della Prof.ssa Fiorella Lunardon e l’intervento della Prof.ssa Marina Brollo. La
relazione e l’intervento evidenziano i due aspetti rilevanti delle citazioni, quali supporto e
rispettivamente quali elementi di valutazione della ricerca ai fini della ripartizione dei Fondi.
Gli atti sono in corso di pubblicazione su Quaderni di Argomenti di Diritto del Lavoro, con
premessa di Mattia Persiani e Franco Carinci, e, oltre alla relazione di Fiorella Lunardon e
all’intervento di Marina Brollo, con contributi di Alessandro Bellavista, Laura Castelvetri, Vito
Leccese, Marco Marazza, Antonio Viscomi, Roberto Pessi, Mariella Magnan
Translation dual of a semifield
No full textIn this paper we obtain a new description of the translation dual of a semifield introduced in [G. Lunardon,
Translation ovoids, J. Geom. 76 (2003) 200–215]. Using such a description we are able to prove that
a semifield and its translation dual have nuclei of the same order. Combining the Knuth cubical array and
the translation dual, we give an alternate description of the chain of twelve semifields in the table of [S. Ball,
G.L. Ebert, M. Lavrauw, A geometric construction of finite semifields, J. Algebra 311 (2007) 117–129]
Open Heavy Flavour Detection in ALICE
No full textThe start of the operation of the Large Hadron Collider (LHC), scheduled for next year, will open a new chapter
for heavy-ion physics. An important new aspect at the LHC, with respect to the existing accelerators, will be the
abundant production of heavy quarks, that are expected to be a key probe of the strongly interacting medium
produced in the collision. We present results on the expected experimental capability for the measurement of
heavy
avour production in the central barrel of ALICE, the dedicated heavy-ion experiment at the LHC
Study of the ALICE performance for the measurement of beauty via the electron decay channel
No full textWe present a strategy for the detection of electrons coming from the semi-electronic decay of
beauty particles generated in Pb–Pb and p–p collisions at LHC using the ALICE detector. The
experiment’s performance for this measurement is evaluated in terms of accessible pt range and
expected uncertainties
Empirical bias-reducing adjustments to estimating functions
No full textWe develop a novel and general framework for reduced-bias -estimation from
asymptotically unbiased estimating functions. The framework relies on an
empirical approximation of the bias by a function of derivatives of estimating
function contributions. Reduced-bias -estimation operates either implicitly,
by solving empirically-adjusted estimating equations, or explicitly, by
subtracting the estimated bias from the original -estimates, and applies to
models that are partially- or fully-specified, with either likelihoods or other
surrogate objectives. Automatic differentiation can be used to abstract away
the only algebra required to implement reduced-bias -estimation. As a
result, the bias reduction methods we introduce have markedly broader
applicability with more straightforward implementation and less algebraic or
computational effort than other established bias-reduction methods that require
resampling or evaluation of expectations of products of log-likelihood
derivatives. If -estimation is by maximizing an objective, then there always
exists a bias-reducing penalized objective. That penalized objective relates
closely to information criteria for model selection, and can be further
enhanced with plug-in penalties to deliver reduced-bias -estimates with
extra properties, like finiteness in models for categorical data. The
reduced-bias -estimators have the same asymptotic distribution as the
original -estimators, and, hence, standard procedures for inference and
model selection apply unaltered with the improved estimates. We demonstrate and
assess the properties of reduced-bias -estimation in well-used, prominent
modelling settings of varying complexity
Good eggs and Veronese varieties
No full textWe give a new proof of the main theorem of \cite{THAS1997} concerning
the connection between good eggs in \PG(4n-1,q), odd, and
Veronese varieties,
using the model for good eggs in \PG(4n-1,q), odd, from \cite{LAVRAUWPENTTILA2001}
