Orbital dynamics and characterization of space debris via optical observations [PDF]

open access: yesINCAS Bulletin, 2023
Studying the long-term dynamical evolution of space debris and the development of optical measurements help us to avoid collision risks caused by these objects.

PERTURBING CONFORMAL TURBULENCE [PDF]

open access: yesModern Physics Letters A, 1995
We consider perturbations of the nonunitary minimal model solutions of two-dimensional conformal turbulence proposed by Polyakov. Demanding the absence of nonintegrable singularities in the resulting theories leads to constraints on the dimension of the perturbing operator.

An Exploration and Exploitation-Based Metaheuristic Approach for University Course Timetabling Problems

open access: yesAxioms, 2023
The university course timetable problem (UCTP) is known to be NP-hard, with solution complexity growing exponentially with the problem size. This paper introduces an algorithm that effectively tackles UCTPs by employing a combination of exploration and ...

PARP3 is a promoter of chromosomal rearrangements and limits G4 DNA

open access: yesNature Communications, 2017
Chromosomal rearrangements are key events in the pathogenesis of a range of disorders. Here the authors utilize a zinc finger nuclease translocation reporter to identify PARP3 as a regulator of these events at sites enriched for G quadruplex DNA.

Privacy-Preserving Schemes for Safeguarding Heterogeneous Data Sources in Cyber-Physical Systems

open access: yesIEEE Access, 2021
Cyber-Physical Systems (CPS) underpin global critical infrastructure, including power, water, gas systems and smart grids. CPS, as a technology platform, is unique as a target for Advanced Persistent Threats (APTs), given the potentially high impact of a

Frame perturbations [PDF]

open access: yesProceedings of the American Mathematical Society, 1995
A frame in a Hilbert space \(X\) is a set of functions \(\{f_i\), \(i\in I\}\) such that \[ \sum_{i\in I}|\langle f,f_i \rangle |^2\sim |f|_X \] defines an equivalent norm on \(X\), i.e., every function \(f\in X\) has a (not necessarily unique) expansion \(f= \sum_{i\in I} c_i f_i\).

A Perturbation Approach for Lateral Excited Vibrations of a Beam-like Viscoelastic Microstructure Using the Nonlocal Theory

open access: yesApplied Sciences, 2021
In this paper, we investigate the lateral vibration of fully clamped beam-like microstructures subjected to an external transverse harmonic excitation. Eringen’s nonlocal theory is applied, and the viscoelasticity of materials is considered.

“Verde di migrazione”. L’estetica perturbante dello straniamento ne La mano che non mordi di Ornela Vorpsi

open access: yesItalies, 2010
Questo articolo analizza la rappresentazione degli effetti dell’alienazione provocati dalla migrazione ne La mano che non mordi di Ornela Vorpsi tramite il legame che essa crea tra frammentazione dell’io e l’incontro con l’estetica.
