Anomaly Cancellation in Six Dimensions [PDF]

, 1993
I show that anomaly cancellation conditions are sufficient to determine the two most important topological numbers relevant for Calabi-Yau compactification to six dimensions.

Testing phenomenological and theoretical models of dark matter density profiles with galaxy clusters [PDF]

, 2013
We use the stacked gravitational lensing mass profile of four high-mass (M& 10 15 M⊙) galaxy clusters around z ≈ 0.3 from Umetsu et al. (2011) to fit density profiles of phenomeno logical (NFW, Einasto, Sersic, Stadel and Hernquist) and theoretical (non ...

A computational framework to establish data-driven constitutive models for time- or path-dependent heterogeneous solids

Scientific Reports, 2021
We propose and implement a computational procedure to establish data-driven surrogate constitutive models for heterogeneous materials. We study the multiaxial response of non-linear n-phase composites via Finite Element (FE) simulations and computational

Phenomenological Implications of Supersymmetric Family Non-universal U(1)-prime Models

, 2009
We construct a class of anomaly-free supersymmetric U(1)' models that are characterized by family non-universal U(1)' charges motivated from E_6 embeddings.

PNNARMA model: an alternative to phenomenological models in chemical reactors [PDF]

, 2001
This paper is focused on the development of non-linear neural models able to provide appropriate predictions when acting as process simulators. Parallel identification models can be used for this purpose.

String Loop Threshold Corrections for N=1 Generalized Coxeter Orbifolds [PDF]

, 2000
We discuss the calculation of threshold corrections to gauge coupling constants for the, only, non-decomposable class of abelian (2, 2) symmetric N=1 four dimensional heterotic orbifold models, where the internal twist is realized as a generalized ...

Non-abelian gauge extensions for B-decay anomalies

Physics Letters B, 2016
We study the generic features of minimal gauge extensions of the Standard Model in view of recent hints of lepton-flavor non-universality in semi-leptonic b→sℓ+ℓ− and b→cℓν decays.

Two Loop R-Symmetry Breaking

, 2008
We analyze two loop quantum corrections for pseudomoduli in O'Raifeartaigh like models. We argue that R-symmetry can be spontaneously broken at two loop in non supersymmetric vacua. We provide a basic example with this property.

Non-perturbative Vacuum Destabilization and D-brane Dynamics [PDF]

, 2010
We analyze the process of string vacuum destabilization due to instanton induced superpotential couplings which depend linearly on charged fields. These non-perturbative instabilities result in potentials for the D-brane moduli and lead to processes of D-

From Minimal Self to Self as Hyper-generalized Sign: Notes for an Integrated Model of Subjectivity

Rivista Internazionale di Filosofia e Psicologia, 2013
This paper proposes a phenomenologically oriented theoretical perspective and it aims at showing that intersubjectivity and its dynamics of sense-making are consistent with an emergentist view of the personal Self.
