description: Soglie del linguaggio. Corpo, mondi, Società, compie una ricognizione e una messa in comunicazione delle molteplici anime che nel Dipartimento di Filosofia, Comunicazione e Spettacolo lavorano, da prospettive diverse e da più anni, sulla tematica del linguaggio. Si è voluta creare così l’opportunità di un dialogo tra l’area di studiosi che guardano più al rapporto tra linguaggio e versante scientifico (biologia, etologia, neuroscienze, psicologia) e l’area volta più allo studio della dimensione sociologico-storico-politica, o fenomenologico-estetica, o psichiatrico-psicoanalitica, o, infine, di pensiero della differenza, con cui guardare all’esperienza linguistica. Partecipano al volume anche studiosi esterni, secondo lo spirito della collana Colloquia Philosophica, il cui intento è quello di facilitare un dialogo non solo all’interno del Dipartimento FILCOSPE, ma anche con altri esponenti della comunità scientifica che vogliano contribuire al confronto su temi e problemi comuni.

description: The purpose of this study was to assess the frequency of optineurin (OPTN) mutation in amyotrophic lateral sclerosis (ALS) patients from mainland China, as well as to characterize the relationship between OPTN mutation and clinical phenotypes. We examined the coding region of OPTN in 511 unrelated Chinese sporadic ALS (SALS) subjects and 204 healthy controls using a PCR direct sequencing strategy. Nine OPTN variants were identified, of which four were novel missense mutations: c.407C > T (p.A136V), c.1184A > G (p.K395R), c.1352T > C (p.I451T), and c.1546G > C (p.E516Q) (all heterozygous). The remaining five variants were already present in single nucleotide polymorphism databases. Patients with OPTN mutations were characterized by spinal onset, although they showed differences in disease progression. In conclusion, this study provides a genetic epidemiological characterization of OPTN mutations in Chinese patients, and our results are consistent with the proposition that such mutations are common in Asian populations.

description: Bilinear systems offer a promising approach for nonlinear control because a broad class of nonlinear problems can be reformulated and approximated in bilinear form. System identification is a technique to obtain such a bilinear approximation for a nonlinear system from input-output data. Recent discrete-time bilinear model identification methods rely on Input-Output-to-State Representations (IOSRs) derived via the interaction matrix technique. A new formulation of these methods is given by establishing a correspondence between interaction matrices and the gains of full-order bilinear state observers. The new interpretation of the identification methods highlights the possibility of utilizing minimal-order bilinear state observers to derive new IOSRs. The existence of such observers is discussed and shown to be guaranteed for special classes of bilinear systems. New bilinear system identification algorithms are developed and the corresponding computational advantages are illustrated via numerical examples.

description: Plasma etching is an important tool in nano-device fabrication. We report a study on argon plasma etching of topological insulator materials Bi2Se3, Bi2Te3, Sb2Te3 and Bi2Te2Se using exfoliated flakes (with starting thicknesses of ~100 nm) derived from bulk crystals. We present data mainly from atomic force microscopy (AFM) and Raman spectroscopy. Through AFM measurements, plasma exposure is observed to decrease the thickness of our samples and increase surface roughness (with height fluctuations reaching as large as ~20 nm). We extract an etching rate for each type of material. Plasma exposure also causes a widening (especially Eg2) of the characteristic Raman peaks, with no significant change in peak position. The overall Raman intensity is observed to initially increase, then decrease sharply after the samples are etched below ~20 nm in thickness. Our findings are valuable for understanding the effects of argon plasma etching on topological insulator materials.

description: Questo volume è il primo risultato di un programma di studio e valorizzazione del complesso delle Mura Aureliane, promosso dalla Sovrintendenza Capitolina ai Beni Culturali e dalle tre Università romane Sapienza, Tor Vergata e Roma Tre. La collaborazione è in atto in diversi ambiti tra i quali l’organizzazione di almeno tre convegni sulle Mura, cui affidare il compito di fare il punto sulle conoscenze acquisite e sui temi di ricerca ancora aperti, nonché di monitorare nel tempo e nei luoghi lo stato di salute del complesso palinsesto murario. Il primo Convegno, di cui oggi pubblichiamo gli Atti, si è svolto il 25 marzo 2015 nella sede del Dipartimento di Architettura di Roma Tre all’ex Mattatoio di Testaccio. Intitolato Le Mura Aureliane nella storia di Roma. 1. Da Aureliano a Onorio e dedicato in particolare al progetto di Aureliano, ha affrontato i temi relativi alla storia della prima costruzione delle Mura fino al V secolo d.C., esaminandola non soltanto dal punto di vista tecnico, nell’analisi delle stratificazioni antiche e delle tipologie murarie originarie ma anche dal punto di vista storico e urbanistico, negli elementi che hanno condizionato il tracciato difensivo. Nella seconda parte della Giornata e nei numerosi poster, inclusi negli Atti, sono stati inoltre presentati i risultati di indagini recenti e di lavori di restauro curati dalla Sovrintendenza, nonché le ricerche, i rilievi e i progetti promossi presso le tre Università coinvolte.

description: Il volume affronta il tema rilevante della finanza della cultura: finanziamento, spesa ed agevolazioni tributarie, in un contesto teorico, oltre che nell’esame della realtà italiane e europea.
Vengono, pertanto, analizzate le fonti di finanziamento delle attività culturali sia da parte del settore pubblico che del settore privato con un’attenzione specifica al no profit. Alcuni dati riguardano l’evoluzione in Italia.
Sempre per l’Italia importa esaminare i flussi finanziari pubblici nel settore della cultura a livello regionale. Nonostante un interesse proclamato, si rileva che in presenza di un patrimonio artistico rilevante, la spesa per la attività culturali, in percentuale del PIL, è tra le più basse dei Paesi europei.
Significativo il lavoro nel quale, sulla base di una indagine sulle elargizioni volontarie alla cultura in Italia e sull’analisi degli incentivi tributari per i contribuenti Irpef, si giunge alla conclusione dell’inconsistenza quantitativa delle donazioni. Importanti le riflessioni sul significato del dono.
Il tema delle sponsorizzazioni culturali viene esaminato da un punto di vista giuridico. Interessante l’analisi di due casi noti quali le sponsorizzazioni aziendali del Colosseo e degli scavi archeologici di Ercolano. Il partenariato tra imprese e pubbliche amministrazioni, nonostante alcune carenze, costituisce uno strumento idoneo alla valorizzazione culturale.
Il settore del contemporaneo rappresenta un campo di interesse specifico che richiede una promozione particolare. Il Piano per l’arte contemporanea del Ministero per i beni e le attività culturali e il turismo vuole incentivare la conoscenza di questo ambito artistico, le esposizioni mirate e le acquisizioni. Le risorse del Piano sono state utilizzate in prevalenza per la realizzazione del Museo MAXXI di Roma.
Il finanziamento delle attività culturali viene visto nei legami tra sfera giuridico-politica, economica e culturale. Per la loro frequente impossibilità a stare sul mercato, tenuto conto delle loro caratteristiche strutturali, le attività culturali hanno bisogno di finanziamenti esterni, pubblici e privati.
L’ultima parte del volume si occupa di temi di natura europea. Si tratta dell’esame della politica culturale dell’Unione europea attraverso i Fondi strutturali e i programmi specifici quali Europa creativa che ha rivisto gli strumenti precedenti.
Viene esaminato anche l’utilizzo dei fondi europei per la cultura in Italia per i programmi a gestione indiretta in alcune Regioni significative: Lazio, Sicilia e Toscana. Nelle prime due Regioni si rilevano lacune in termini di efficienza. Per i finanziamenti a gestione diretta la situazione è certamente migliore.
Attente e approfondite sono le analisi sulla finanza della cultura in Gran Bretagna e Francia, Paesi che presentano caratteristiche specifiche ed originali.

description: La presenza millenaria degli ebrei in Marocco è una verità attestata da tutti i documenti storici. La loro partenza alla volta di Europa, America e Israele a cominciare dalla seconda metà del ventesimo secolo diviene sempre più preoccupante per il patrimonio culturale marocchino. La sopravvivenza di questa eredità plurisecolare risultante dalla convivenza di ebrei, arabi e amazigh musulmani in Marocco dipende ormai dalla buona volontà di un’élite intellettuale, poiché la volontà politica c’è ed è chiaramente espressa nella Nuova Costituzione del 2011. Quali sono dunque i mezzi di cui dispongono gli intellettuali marocchini, gli insegnanti ricercatori in particolare, per far vivere la cultura plurisecolare giudeo-marocchina nella memoria delle giovani generazioni? In questo articolo illustreremo le circostanze infelici che hanno favorito la confusione identitaria degli ebrei marocchini. Spiegheremo la natura della missione degli intellettuali marocchini chiamati ad affrontare questa sfida etica. Analizzeremo infine un esempio di supporto didattico con cui superare questa sfida.

description: The uranium mononitride (UN) is a material considered as a promising candidate for Generation-IV nuclear reactor fuels. Unfortunately, oxygen in air affects UN fuel performance and stability. Therefore, it is necessary to understand the mechanism of oxygen adsorption and further UN oxidation in the bulk and at surface. Recently, we performed a detailed study on oxygen interaction with UN surface using density functional theory (DFT) calculations. We were able to identify an atomistic mechanism of UN surface oxidation consisting of several important steps, starting with the oxygen molecule dissociation and finishing with oxygen atom incorporation into vacancies on the surface. However, in reality most of processes occur at the interfaces and on UN grain boundaries. In this study, we present the results of first DFT calculations on O behaviour inside UN grain boundaries performed using GGA exchange-correlation functional PW91 as implemented into the VASP computer code. We consider a simple interface (310)[001](36.8°) tilt grain boundary. The N vacancy formation energies and energies of O incorporation into pre-existing vacancies in the grain boundaries as well as O solution energies were compared with those obtained for the UN (001) and (110) surfaces.

description: When excited by an input consisting of a number of discrete levels, a bilinear system becomes a linear time-varying system whose dynamics switches from one linear subsystem to another depending on the input level. This paper describes an identification method that uses the concept of a superstate of a linear switching system as a superstate of the bilinear system. In a superspace method, these superstates are used directly to identify a bilinear system model. In a subspace method, two or more superstate representations are intersected to find a reduced dimension subspace prior to identification of a bilinear model.

description: The structure and magnetic properties in doped Heusler alloys of Mn2CoGa and Mn2CoAl have been investigated by experiments and calculations. The main group elements of Ga and Al are substituted by the magnetic or non-magnetic transition metals, Co, Cu, V, and Ti in the alloy systems. Three kinds of local ferromagnetic structures, Co-Mn-Co, Mn-Co-Mn and Mn-Co-V, have been found. They embed in the native ferrimagnetic matrix and increase the magnetization with different increments. The Co-Mn-Co ferromagnetic structure shows the largest increment of 6.18μB /atom. In addition, interesting results for non-magnetic Cu increasing the magnetization and the V atom having a large ferromagnetic moment of about 1.0μB have been obtained. The exchange interaction energy can be increased by the newly added Co and depleted by supporting a ferromagnetic coupling in other substitution cases, and showing the variation of the TC. Our calculation of electronic structure verifies the strong d-d hybridization when the three ferromagnetic structures are achieved. It has also been found that the covalent effect from the Ga and Al determines the generation of the local ferromagnetic structure and the tolerance for dopant content.

title:  The Effects of Hackberry Psyllids on Refueling Migratory Songbirds and Autumnal Seed Rain
Creators: name: Hines, Chance H.
Publisher: name: Old Dominion University Libraries
Year: 2020

description: Hackberry psyllids (Pachypsylla sp) are a galling insect native to North America’s hackberry trees (Celtis sp). Hackberry leaf-galling psyllids are ephemerally abundant during autumn, a period of time when migratory songbirds are traveling from their breeding areas in temperate North America south to their winter ranges. These migrations are energetically taxing and many songbirds fuel their journey with resources like insects and fruits. I captured birds with mist nets, observed foraging behaviors, and captured avian-dispersed fleshy fruit seeds (hereafter, seed rain) rain during the autumn of 2016 and 2017 to determine how hackberry psyllids, an ephemerally abundant insect, affect migrating songbird refueling indices estimated from blood samples, foraging activity, and subsequent bird-dispersed seed rain patterns. I used end-point assays to measure bird metabolites to find that hackberry presence and hackberry psyllid were associated with increased protein metabolism and fat accumulation for insectivores and omnivores. I also found that hackberry seeds were most dispersed when hackberry psyllids were present. Allospecific seed rain was greater when eastern bacchharis (Baccharis hamifolia) shrubs were treated with hackberry leaves and hackberry psyllids, and allospecific seed rain was greater near hackberry trees and when hackberry psyllids were present within mixed-hardwood forests. This study adds to the growing support that insects play a crucial role for refueling migratory songbird stopover sites and that hackberry psyllids can increase the likelihood that hackberry seeds are dispersed away from the host tree and allospecific fruiting seeds are dispersed nearer the host tree.

description: In recent decades, the pervasive integration of Information and Communications Technology (ICT) has catalyzed substantial transformations, positioning ICT as a pivotal subject within economic analysis and as a catalyst for growth. Nonetheless, it is imperative to acknowledge that the adoption of ICT exhibits a pronounced discrepancy between developed and developing regions. This study delves into the landscape of ICT adoption, particularly focusing on the substantial variance in utilization levels across different global regions. Drawing on data from Internet World Stats (2017), which reveals a strikingly low internet penetration rate in Africa—merely 353 million internet users out of a total global population of 3 billion—the study elucidates the considerable digital divide between Africa and other developed regions such as Europe, where internet penetration rates soar as high as 77%. The discourse unfolds by contextualizing the critical importance of ICT adoption within the broader framework of economic analysis and growth dynamics. Through an examination of pertinent literature and empirical evidence, the study underscores the pivotal role that ICT plays as a driver of economic development, innovation, and productivity enhancement. Furthermore, it probes into the various factors contributing to the stark contrast in ICT adoption rates between developed and developing nations, ranging from infrastructural constraints and socioeconomic disparities to policy frameworks and institutional environments.

The findings of this study hold significant implications for policymakers, practitioners, and scholars alike. By shedding light on the multifaceted dynamics underpinning ICT adoption, the study offers valuable insights into devising strategies aimed at bridging the digital divide and fostering inclusive growth trajectories. Moreover, it underscores the urgent need for concerted efforts to address the underlying barriers hindering widespread ICT adoption in developing regions, thereby unlocking the transformative potential of technology to drive socioeconomic progress and mitigate global disparities

description: Bilinear systems are important per se since several phenomena in engineering and other fields are inherently bilinear. Even more interestingly, bilinear systems can approximate more general nonlinear systems, providing a promising approach to handle various nonlinear identification and control problems, such as satellite attitude control. This paper develops and demonstrates via numerical examples a method for discrete-time state-space model identification for bilinear systems in the presence of noise in the process and in the measurements. The formulation relies on a bilinear observer which is proven to have properties similar to the linear Kalman filter under the sole additional assumption of stationary white excitation input, and on a novel approach to system identification based on the estimation of the observer residuals. The latter are used to construct a new, noise-free identification problem, in which the observer is identified and the matrices of the system state-space model are recovered. The resulting method represents the bilinear counterpart of the Observer/Kalman filter Identification (OKID) approach for linear systems, originally developed for the identification of lightly-damped structures and distributed by NASA.

description: We present deep surface photometry of a volume--limited sample of 21 UM emission line galaxies in broadband optical UBVRI and near infra-red (NIR) HKs filters. The sample comprises 19 blue compact galaxies (BCGs) and two spirals. For some targets the exposure times are the deepest to date. For the BCG UM462 we observe a previously undetected second disk component beyond a surface brightness level of mu_B=26 mag arcsec^{-2}. This is a true low surface brightness component with central surface brightness mu_0=24.1 mag arcsec^{-2} and scale length h_r=1.5 kpc. All BCGs are dwarfs, with M_B>=-18, and very compact, with an average scale length of h_r~1 kpc. We separate the burst and host populations for each galaxy and compare them to stellar evolutionary models with and without nebular emission contribution. We also measure the A_{180} asymmetry in all filters and detect a shift from optical to NIR in the average asymmetry of the sample. This shift seems to be correlated with the morphological class of the BCGs. Using the color-asymmetry relation, we identify five BCGs in the sample as mergers, which is confirmed by their morphological class. Though clearly separated from normal galaxies in the concentration-asymmetry parameter space, we find that it is not possible to distinguish luminous starbursting BCGs from the merely star forming low luminosity BCGs.

description: The results of DFT supercell calculations of oxygen behavior upon the UN (001) and (110) surfaces as well as at the tilt grain boundary are presented. Oxygen adsorption, migration, incorporation into the surface N vacancies on (001) and (110) surfaces have been modeled using 2D slabs of different thicknesses and supercell sizes. The temperature dependences of the N vacancy formation energies and oxygen incorporation energies are calculated. We demonstrate that O atoms easily penetrate into UN surfaces and grain boundaries containing N vacancies, due to negative incorporation energies and a small energy barrier. The Gibbs free energies of N vacancy formation and O atom incorporation therein at the two densely-packed surfaces and tilt grain boundaries are compared. It has been also shown that the adsorbed oxygen atoms are highly mobile which, combined with easy incorporation into surface N vacancies, explains efficient (but unwanted) oxidation of UN surfaces. The atomistic mechanism of UN oxidation via possible formation of oxynitrides is discussed.

A spatially resolved SSC Shock-in-Jet model

Publisher: name: arXiv
Year: 2012
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: In this paper a spatially resolved, fully self-consistent SSC model is presented. The observable spectral energy distribution (SED) evolves entirely from a low energetic delta distribution of injected electrons by means of the implemented microphysics of the jet. These are in particular the properties of the shock and the ambient plasma, which can be varied along the jet axis. Hence a large variety of scenarios can be computed, e.g. the acceleration of particles via multiple shocks. Two acceleration processes, shock acceleration and stochastic acceleration, are taken into account. From the resulting electron distribution the SED is calculated taking into account synchrotron radiation, inverse Compton scattering (full cross section) and synchrotron self absorption. The model can explain SEDs where cooling processes are crucial. It can verify high variability results from acausal simulations and produce variability not only via injection of particles, but due to the presence of multiple shocks. Furthermore a fit of the data, obtained in the 2010 multi-frequency campaign of Mrk501, is presented.

description: This paper presents a unified approach for the identification of linear state-space models from input-output measurements in the presence of noise. It is based on the established Observer/Kalman filter IDentification (OKID) method of which it proposes a new formulation capable of transforming a stochastic identification problem into a (simpler) deterministic problem, where the Kalman filter corresponding to the unknown system and the unknown noise covariances is identified. The system matrices are then recovered from the identified Kalman filter. The Kalman filter can be identified with any deterministic identification method for linear state-space models, giving rise to numerous new algorithms and establishing the Kalman filter as the unifying bridge from stochastic to deterministic problems in system identification.
Star-formation laws in extreme starbursts

description: The observational study of star-formation laws is paramount to disentangling the physical processes at work on local and global scales in galaxies. To this aim we have expanded the sample of extreme starbursts, represented by local LIRGs and ULIRGs, with high-quality data obtained in the 1-0 line of HCN. The analysis of the new data shows that the star-formation efficiency of the dense molecular gas, derived from the FIR/HCN luminosity ratio, is a factor 3-4 higher in extreme starbursts compared to normal galaxies. We find a duality in the Kennicutt-Schmidt laws that is enhanced if we account for the different conversion factor for HCN (alpha_HCN) in extreme starbursts and correct for the unobscured star-formation rate in normal galaxies. We find that it is possible to fit the observed differences in the FIR/HCN ratios between normal galaxies and LIRGs/ULIRGs with a common constant star-formation rate per free-fall time (SFR_ff) if we assume that HCN densities are ~1-2 orders of magnitude higher in LIRGs/ULIRGs, and provided that SFR_ ff~0.005-0.01 and/or if alpha_HCN is a factor of a few lower than our favored values.

description: Purpose/aim of the study: To conduct a survey spectrum of the PITX2, FOXC1, and PRDM5 genes to reveal genotype–phenotype correlations in a cohort of Southeastern Chinese patients with Axenfeld–Rieger syndrome (ARS). Materials and methods: A total of 20 probands with ARS were recruited in Southeast China. All patients underwent full ocular and systemic examinations. Sanger sequencing was used to analyze all coding regions of and regions adjacent to PITX2, FOXC1, and PRDM5 and 13 upstream regulatory elements of PITX2. Multiplex ligation-dependent probe amplification was performed to detect gross insertions and deletions in PITX2 and FOXC1. Quantitative polymerase chain reaction was used to detect copy number variations in regulatory elements of PITX2. A bioinformatics analysis was conducted to evaluate the pathogenicity of variants. Results: Eleven mutations, including eight novel mutations, were identified in PITX2. Seven of the mutations were truncations. A genotype–phenotype correlation analysis showed that 81.8% (9/11) of patients with mutations in PITX2 developed glaucoma before reaching 10 years old. The proportion of patients without detected mutations was only 33.3% (3/9, P = 0.0399). In patient G1399, ultrasound biomicroscopy revealed that the left eye exhibited a phenotype similar to aniridia with complete angle closure and a remaining stub of iris tissue. Conclusion: This is the first genetic study of a cohort of Southeastern Chinese patients with ARS. Eight novel mutations were detected, expanding the mutation spectrum of PITX2. PITX2 may be a major candidate gene for ARS in Southeastern Chinese patients. Truncations may be the primary mutation type in PITX2. Glaucoma onset may be earlier in patients with mutations in PITX2 than in those without mutations in PITX2 and FOXC1. A block of the anterior chamber angle by the end of the iris might represent the main factor influencing the development of glaucoma in ARS patients with an asymmetric aniridia phenotype.
