description: Many solar filaments and prominences show short-lived horizontal threads lying parallel to the photosphere. In this work the possible link between Rayleigh-Taylor instabilities and thread lifetimes is investigated. This is done by calculating the eigenmodes of a thread modelled as a Cartesian slab under the presence of gravity. An analytical dispersion relation is derived using the incompressible assumption for the magnetohydrodynamic (MHD) perturbations. The system allows a mode that is always stable, independently of the value of the Alfvén speed in the thread. The character of this mode varies from being localised at the upper interface of the slab when the magnetic field is weak, to having a global nature and resembling the transverse kink mode when the magnetic field is strong. On the contrary, the slab model permits another mode that is unstable and localised at the lower interface when the magnetic field is weak. The growth rates of this mode can be very short, of the order of minutes for typical thread conditions. This Rayleigh-Taylor unstable mode becomes stable when the magnetic field is increased, and in the limit of strong magnetic field it is essentially a sausage magnetic mode. The gravity force might have a strong effect on the modes of oscillation of threads, depending on the value of the Alfvén speed. In the case of threads in quiescent filaments, where the Alfvén speed is presumably low, very short lifetimes are expected according to the slab model. In active region prominences, the stabilising effect of the magnetic tension might be enough to suppress the Rayleigh-Taylor instability for a wide range of wavelengths.

description: In the PANDA experiment at the FAIR facility at GSI two DIRC (Detection of Internally Reflected Cherenkov light) detectors will be used for $π$/K separation up to 4 GeV/c. Due to their location in a high magnetic field and other stringent requirements like high detection efficiency, low dark count rate, radiation hardness, long lifetime and good timing, MCP-PMTs (microchannel-plate photomultiplier) were the best choice of photon sensors for the DIRC detectors in the PANDA experiment. This paper will present the performance of some of the latest 2$\times$2 inch$^2$ MCP-PMTs from Photek and Photonis, including the first mass production tubes for the PANDA Barrel DIRC from Photonis. Performance parameters like the collection efficiency (CE), quantum efficiency (QE), and gain homogeneity were determined. The effect of magnetic fields on some properties like gain and charge cloud width was investigated as well. Apart from that the spatial distribution of many internal parameters like time resolution, dark count rate, afterpulse ratio, charge sharing crosstalk and recoil electrons were measured simultaneously with a multihit capable DAQ system. The latest generation of Photonis MCP-PMTs shows an unexpected "escalation" effect where the MCP-PMT itself produces photons.

description: Un’infrastruttura verde nel contesto regionale della Sardegna Molti studi recenti sono incentrati sulle infrastrutture verdi come generatrici dell’offerta di una vasta gamma di servizi ecosistemici, soprattutto con riferimento agli ambienti urbani, e sui corridoi ecologici quali strutture di connessione che limitano la frammentazione del paesaggio. Tuttavia, non sono molti i lavori di ricerca che hanno preso in esame l’integrazione delle due categorie concettuali nella prospettiva della definizione e dell’attuazione di politiche ed operazioni di piano su di esse fondate. Utilizzando il territorio della Sardegna come caso di studio, si propone un approccio metodologico che combina le due categorie concettuali, basato sul riconoscimento di un’infrastruttura verde regionale legata all’offerta di molteplici servizi ecosistemici e su una rete di corridoi ecologici, identificata in relazione alla mappatura della resistenza al movimento delle specie. La stima di una regressione multipla dà modo di identificare queste correlazioni, che si evidenziano, in particolare, con riferimento a tre servizi ecosistemici su cui devono focalizzarsi le politiche e le operazioni della pianificazione spaziale: la regolazione del microclima nei contesti locali, i benefici offerti da foreste ed aree boscate ed i servizi legati all’identità culturale ed al patrimonio storico e naturalistico.

description: In this paper we study the macroscopic conduction properties of large but finite binary networks with conducting bonds. By taking a combination of a spectral and an averaging based approach we derive asymptotic formulae for the conduction in terms of the component proportions p and the total number of components N. These formulae correctly identify both the percolation limits and also the emergent power law behaviour between the percolation limits and show the interplay between the size of the network and the deviation of the proportion from the critical value of p = 1/2. The results compare excellently with a large number of numerical simulations.

description: Applicando alla città di Napoli forme di didattica sperimentale sugli effetti del cambiamento climatico, il contributo guarda agli “esperimenti climatici urbani” a partire da un laboratorio universitario di ricerca-azione che, ponendosi all’interfaccia fra istituzioni e società civile, facilita la connessione fra politiche e pratiche climatiche. Esplicitando come la collaborazione con il Laboratorio Azione Clima (LAC) di UniNa abbia dato origine a reti temporanee per l’azione climatica dal basso, il paper mette in luce le potenzialità della ricerca e della didattica universitaria sul fronte del public engagement. Si tratta di un impegno che, tenendo conto dei ritardi e delle difficoltà delle amministrazioni locali, è volto a configurare domande situate di adattamento e mitigazione, trattando la governance climatica come trama per azioni collaborative che incidano sulle decisioni pubbliche. La sfida del LAC, entro questo orizzonte, è territorializzare il contrasto al CC mettendo in primo piano i diritti connessi alla giustizia climatica.

Climate adaptation and Water Sensitive Urban Design: the case study of a university campus in the city of L’Aquila
Creators: name: Sette, Camilla
Publisher: name: Bulletin of the Calza Bini Center
Year: 2023

description: Climate change will drive global temperatures to unprecedented temperature peaks by 2050 and, at the same time, it will increase the frequency and intensity of extreme precipitation events worldwide, with estimated return times of as much as 100 or 200 years for recorded precipitation amounts. Urban and peri-urban areas are the most affected by the effects of climate change, due to their highly sealed surfaces that make it impossible for water to filter into the ground. The issue has been further worsened since land consumption has exceeded certain limits. Therefore, in order to achieve climate adaptation of urban and peri-urban areas, resilient and adaptive retrofit interventions will have to made, placed within the broader framework of Water Sensitive Urban Design (WSUD) and Nature Based Solutions. The study area for the urban regeneration project is located in Italy, in the immediate western suburbs of the city of L’Aquila, the capital of Abruzzo. Keywords: climate adaptation, urban regeneration, urban planning, sustainability, design

description: Quantum networks will support long-distance quantum key distribution (QKD) and distributed quantum computation, and are an active area of both experimental and theoretical research. Here, we present an analysis of topologically complex networks of quantum repeaters composed of heterogeneous links. Quantum networks have fundamental behavioral differences from classical networks; the delicacy of quantum states makes a practical path selection algorithm imperative, but classical notions of resource utilization are not directly applicable, rendering known path selection mechanisms inadequate. To adapt Dijkstra's algorithm for quantum repeater networks that generate entangled Bell pairs, we quantify the key differences and define a link cost metric, seconds per Bell pair of a particular fidelity, where a single Bell pair is the resource consumed to perform one quantum teleportation. Simulations that include both the physical interactions and the extensive classical messaging confirm that Dijkstra's algorithm works well in a quantum context. Simulating about three hundred heterogeneous paths, comparing our path cost and the total work along the path gives a coefficient of determination of 0.88 or better.

description: In Mozambique there is no evidence of a bankruptcy prediction model developed in the national economic context, yet, back in 2016, the national banking sector suffered a financial shock that resulted in Mozambique Central Bank intervention in two banks (Moza Banco, S.A. and Nosso Banco, S.A.). This was a result of the deterioration of their financial and prudential indicators, although Mozambique had been adhering to the Basel Accords since 1994. The Basel Accords provides recommendations on banking sector supervision worldwide with the aim to enhance financial system stability. While it does not predict bankruptcy, the prediction model can be used as an auxiliary tool to manage that risk, but this has to be built in the national economic context. This paper develops for Mozambique banking sector a bankruptcy prediction model in the Mozambican context through the linear discriminant analyses method, following two assumptions: (i) composition of the sample and (ii) robustness of the financial prediction indicators (the capital structure, profitability asset concentration and asset quality) from 2012 to 2020. The developed model attained an accuracy level of 84% one year before Central Bank intervention (2015) with the entire population of 19 banks of the sector, which makes it recommendable as a risk management tool for this sector.

Respiratory mechanics and diaphragmatic fatigue during exercise in men and women
Creators: name: Guenette, Jordan Ali
Publisher: name: University of British Columbia
Year: 2010

description: Purpose: The purpose of this thesis was to determine the underlying mechanisms associated with a higher total WOB in women (Study 1) and to determine if women experience greater levels of diaphragmatic fatigue relative to men (Study 2). Methods: Study 1: Sixteen endurance-trained subjects (8M:8F) underwent a progressive cycling test to exhaustion while esophageal pressure and lung volumes were measured. Modified Campbell diagrams were used to calculate the inspiratory and expiratory resistive and elastic components at 50, 75, 100 l·min⁻¹ and maximal ventilations and also at standardized mass-corrected work-rates. Study 2: Thirty-eight endurance-trained subjects (19M:19F) underwent a constant-load cycling test at 90% of peak work-rate until exhaustion. Pressure-time product of the diaphragm (PTPdi) was calculated during exercise. Trans-diaphragmatic pressure twitches (Pdi,tw) were assessed using cervical magnetic stimulation before and 10, 30 and 60 minutes after exercise. Diaphragm fatigue was defined as a ≥ 15% reduction in Pdi,tw post-exercise. Results: Study 1: The inspiratory resistive WOB was higher in women at all absolute ventilations (P<0.05). The expiratory resistive WOB was higher in women at 75 l·min⁻¹ (P<0.05). There were no sex-differences in the elastic WOB. However, the total WOB was significantly higher in men at relative percentages of maximal ventilation (P<0.05) but this sex-difference was reversed when the WOB was standardized for a given work-rate to body mass ratio. Study 2: Diaphragm fatigue was present in 11 males and 8 females. The reduction in Pdi,tw at 10 and 30 min following exercise was significantly greater in men relative to women (P<0.05). Men consistently had higher absolute values for PTPdi during exercise but this sex-difference was reversed when body mass was taken into account. Over time, men continued to have a reduced contribution of the diaphragm to total inspiratory force output whereas diaphragmatic contribution in women remained relatively constant over time. Conclusions: The higher total WOB in women is due to an increased resistive WOB which is likely attributable to their smaller airways. Despite a respiratory system that may have a higher mechanical cost of breathing, women appear to be more resistant to exercise-induced diaphragmatic fatigue.

description: The present research aims to provide a practical numerical tool for the mechanical analysis of nanoscale trusses with similar accuracy to molecular dynamics (MD). As a first step, MD simulations of uniaxial tensile and compression tests of all possible chiralities of single-walled carbon nanotubes up to 4 nm in diameter were performed using the AIREBO potential. The results represent a dataset consisting of stress/strain curves that were then used to develop a neural network that serves as a surrogate for a constitutive model for all nanotubes considered. The cornerstone of the new framework is a partially input convex integrable neural network. It turns out that convexity enables favorable convergence properties required for implementation in the classical nonlinear truss finite element available in Abaqus. This completes a molecular dynamics-machine learning-finite element framework suitable for the static analysis of large, nanoscale, truss-like structures. The performance is verified through a comprehensive set of examples that demonstrate ease of use, accuracy, and robustness.

description: Lo studio progettuale per la Nuova Stazione Marittima di Levante aggiunge un importante tassello metodologico alle sperimentazioni sul ruolo rifondativo dell’Architettura delle infrastrutture in alcuni Porti del Sud. Dimostra che la riconfigurazione dei “campi relazionali” del paesaggio urbano può coinvolgere il tracciato delle linee ferroviarie, da sempre considerate barriere non modificabili. Grazie al coinvolgimento di RFI, si delinea una soluzione che concilia due scenari in conflitto: l’ampliamento del porto commerciale di Napoli, la restituzione di un rapporto con il mare al quartiere orientale della città. Le esigenze tecniche di sviluppo del nodo intermodale, la “domanda urbana” di un lungomare capace di essere rappresentativo di un quartiere a scala geografica insieme alla valorizzazione delle attrezzature esistenti e alla ricostruzione della memoria insediativa, trovano sintesi in un’architettura dell’infrastruttura capace di modulare spazi e bisogni apparentemente antitetici, conferendo rinnovato carattere e identità all’area. Ne deriva la rifondazione di un rapporto di fiducia tra progetto di architettura e città contemporanea che trova nel suo farsi le radici e le ragioni di un codice genetico da interpretare e proiettare nel futuro.

Tangible and intangible multiple risks: achieving resilience by enhancing cultural heritage
Creators: name: Sepe, Marichela
Publisher: name: Bulletin of the Calza Bini Center
Year: 2023

description: Multiple kinds of crisis more and more occur simultaneously, making difficult to resolve challenging urban conditions as different risks are overlapped and involve social, economic, environmental, health and liveable topics. Furthermore, any place is different and has its peculiarities with respect to material and immaterial characteristics and, for this reason, has different times and modalities to face crisis. To achieve a sustainable adaptation and regeneration of the places affected by multiple risks it is important to study the questions by many points of view and using suitable urban methods. Starting from these premises, aims of this study (carried out in the framework of the ‘PRIN2020 20209F3A37’ research project, within the ISMed-CNR Unit with the author’s responsibility and the relative agreement between Sapienza Università di Roma and ISMed-CNR) include: to define and identify what are the kinds of risk and the main kinds of overlapping among them in sites; to identify what are the main places which are subjected at multiples risks; to propose an original and ad hoc method to comprehend what are the better and sustainable solutions in terms of adaptation and regeneration of different kinds of places interested by multiple crisis and by enhancing cultural heritage. Finally, principles for multiple risk areas design will be reported. Keywords: multiple risks, cultural heritage, urban regeneration, public spaces

The contributions of spirituality and religious practices to children's happiness
Creators: name: Wallace, Judith Maureen
Publisher: name: University of British Columbia
Year: 2010

description: The relations between happiness and spirituality and religious practices in children aged 8-12 years were examined. Participants included 320 students in Grades 4-6 in both public and private (faith based) schools in Western Canada and their parents. Children rated their happiness using the Subjective Happiness Scale and the Oxford Happiness Questionnaire, Short Form, their spirituality using the Spiritual Well-Being Questionnaire, and their religiousness using the Religious Practice Scale adapted from the Brief Multidimensional Measurement of Religiousness/Spirituality. In addition, parents rated their children’s happiness using the Faces Scale, a single-item measure. Bivariate correlations indicated religious practices were not related to children’s happiness. Multiple regression analyses indicated that spirituality accounted for between 5-25% of the variance in children’s happiness, depending on the person rating happiness (i.e., parents vs. children), and the happiness measure utilized. The Personal domain of spirituality accounted for a unique amount of the variance in children’s happiness over and above the combined effect of all spirituality variables, again depending on the person rating happiness (i.e., parents vs. children), and the happiness measure utilized. Children who reported higher levels of meaning, purpose, and values in their own life reported higher levels of happiness as rated by themselves and their parents. Hierarchical regression analyses indicated that spirituality accounted for between 6-28% of the variance in children’s happiness, depending on the person rating happiness (i.e., parents vs. children), and the happiness measure utilized when gender and school were controlled for. Gender did not explain any of the happiness variance but school (public vs. private) did. The results of the current study parallel research investigating the relation between happiness and spirituality and religion in adolescents and adults. Limitations of the current study and future direction for research in spirituality and happiness are discussed.

description: Si riporta nel contributo a seguire il racconto di un’esperienza articolata tra ricerca, didattica e terza missione elaborata da ricercatori del Dipartimento di Architettura di Napoli a partire dal primo lockdown nella primavera 2020 sino all’anno successivo, in riferimento a un caso studio nel Meridione d’Italia. La riflessione è nata a partire dalla occasione di redazione del Programma Integrato Città Sostenibili (PICS) del Comune di Casoria. La condizione emergenziale, in Italia largamente gestita attraverso la negazione all’uso di spazi aperti e aree di naturalità, in politiche basate su un paradigma di controllo, ha condotto a misurare le scelte progettuali con le rinnovate esigenze di consentire l’uso collettivo degli spazi di prossimità, senza trascurare le connessioni con un processo di transizione strutturale e di lungo termine. Il lavoro svolto definisce, quindi, prefigurazioni progettuali, ma inserendole in articolate strategie multiscalari per riabitare “luoghi comuni” della città di Casoria in totale o parziale dismissione. Architetti e urbanisti “co-costruttori dello spazio” fisico, hanno contribuito ad attivare un processo di transizione verso una città più aperta inclusiva e sostenibile.

description: In the standard model of neutrino oscillations, the neutrino flavor states are mixtures of mass-eigenstates, and the phenomena are well described by the neutrino mixing matrix, i.e., the PMNS matrix. I review the recent progress on parametrization of the neutrino mixing matrix. Besides that I also discuss on the possibility to describe the neutrino oscillations by a non-standard model in which the neutrino mixing is caused by the Lorentz violation (LV) contribution in the effective field theory for LV. We assume that neutrinos are massless and that neutrino flavor states are mixing states of energy eigenstates. In our calculation the neutrino mixing parts depend on LV parameters and neutrino energy. The oscillation amplitude varies with the neutrino energy, thus neutrino experiments with energy dependence may test and constrain the Lorentz violation scenario for neutrino oscillation.

description: L’articolo intende esplicitare gli esiti di una ricerca progettuale che prova a sistematizzare alcune questioni che interessano i processi di trasformazione e rigenerazione di aree ai margini della città consolidata. Questo studio, svolto nell’ambito di una più ampia ricerca scientifica, si interroga sulla determinazione di possibili metodologie di intervento in aree periferiche e abbandonate. L’area a sud della stazione centrale di Napoli è stata indagata e approfondita per aprire una riflessione critica verso un’idea di città che si fonda sulla definizione di nuove sequenze urbane pensate per accogliere e includere, dove il sistema dello spazio pubblico, articolato e differenziato, diviene sostanziale matrice formale della proposta progettuale. Il progetto si pone così come un processo aperto che propone specifiche soluzioni esito di attente letture e analisi dell’ambiente nella sua totalità. Parole chiave: trasformazione urbana, rigenerazione urbana, spazio pubblico, aree periferiche e abbandonate, Napoli Est

description: In the context of regeneration and maintenance processes of the built environment, the paper identifies the values of material and immaterial culture as requirements to be respected to guide interventions for the reuse of urban voids as spaces of collective use for the community. Considering the recreational-artistic use as a driver of the transformation of the built environment, the need-performance methodological approach allows to analyze the outcomes of desk research on best practices playground to build, according to a systemic vision of reality, community engagement tools for the regeneration process stages. From the elaboration of the surveys, diversified concerning the tools tracked and international regulation goals, the paper returns a system of requirements to support the transformation processes of the built environment. These outcomes were tested and transferred in the research project ‘Playgrounds and Art for Communities in Transition: a pact of care for cities’, funded by the University of Naples Federico II. Keywords: reuse, need-performance approach, collective space infrastructure, urban voids, transgible value

description: Il tema degli spazi pubblici è uno dei più dibattuti e coinvolgenti della progettazione urbanistica. Tra gli spazi pubblici quelli sul mare rivestono un particolare fascino perché consentono anche la fruizione di una delle risorse naturali di maggior pregio che una città possa godere. Questa consapevolezza induce a riflettere con maggior attenzione e intensità al loro ruolo, in quanto costituiscono una “saldatura” tra la città consolidata e il mare (Carta, 2008), e alle modalità con cui realizzare l'incremento quantitativo e qualitativo di questi spazi pubblici, ponendo attenzione alla tutela e alla valorizzazione del patrimonio identitario e paesaggistico, allo sviluppo della mobilità sostenibile e al miglioramento delle componenti ambientali. In questo ambito il contributo propone un’analisi dello stato dell’arte nella letteratura scientifica sull’argomento mediante lo studio di due progetti (uno realizzato e l’altro in corso di realizzazione) nel Comune di Bari, una delle 14 città metropolitane italiane che attraverso i fondi europei di coesione sta investendo maggiormente sugli spazi pubblici e sul proprio fronte mare. Individuati criteri flessibili e qualitativi maggiormente pertinenti ai casi da esaminare, si propongono alcune conclusioni sugli esiti: nel primo caso, di un progetto già realizzato e, nel secondo, di un progetto in corso di realizzazione. Parole chiave: rigenerazione urbana, frontemare, pianificazione urbanistica, progetto urbano

description: La maggiore consapevolezza del ruolo delle risorse naturali nel raggiungimento della resilienza urbana richiede nuove politiche tecniche e di pianificazione, per l’applicazione di approcci efficaci per la rigenerazione del patrimonio edilizio esistente. In questo contesto, la ricerca applica i concetti di Urban Metabolism e di Urban Mining (UM) per definire una proposta di strategie di pianificazione per la gestione dei flussi di rifiuti da costruzione e demolizione (CDW) che attraversano il territorio. La ricerca si colloca nell’ambito del contesto tecnico-giuridico nazionale e in particolare porta attenzione alle aree del peri-urbano, individuate quali ambito di studio dalla ricerca Eco Regen1. Il contributo indaga, nello specifico, gli aspetti legati al ciclo di vita dell’ambiente costruito, implementando il progetto di rigenerazione urbana con processi per la gestione dei flussi di CDW, con l’obiettivo di sviluppare filiere alla scala locale attraverso la designazione di eco-distretti. Parole chiave: economia circolare, urban mining, metabolismo urbano, rifiuti da costruzione e demolizione, wastescapes

description: The city, and especially the metropolitan city, has expelled nature: planted areas have been gradually shrinking over time. Biodiversity has been greatly reduced, the air is increasingly polluted, heat islands are multiplying, causing costs especially for the older and marginalised and young people. Soil has been systematically sealed, having been regarded as a resource to be used in building/residential production, ignoring its regenerative potential: it has been seen as a factor capable of developing high property rents. More than for its bio-ecological characteristics, it has been considered as passive physical matter. Sometime, as a source of value capture and/or land equalisation processes. Little attention has been paid to the soil as a complex ecosystem that has formed over the centuries through the disintegration of rocks under the pressure of atmospheric events (rain, wind, various volcanic phenomena, temperature variations, etc.). Lichens, fungi, bacteria, worms and various insects have combined with the various particles thus formed. Plants growing on the soil were gradually added to the plants that had already decomposed over time. The plants, consumed as food by animals (which in turn fertilise the soil itself with their production of biological waste) gradually enriched the soil with new minerals. Especially in large/metropolitan cities, empty/open soils have been subjected to instrumental use: they have been asphalted and cemented/built over. At other times they have been abandoned to progressive decay. The result is an absolute inadequacy in their management in relation to the needs connected with the ecological crisis and climate change. In practice, traditional urban planning has contributed to using nature in an entirely instrumental sense, having been characterised for the most part by a rationality grounded on economic matrix: reductive of multidimensionality, complexity, heterogeneity. The urban planning of negotiations, of bargaining, of territorial marketing, is one recent example. Attention has ended up focusing on volume density, form, possible real estate trends, possibilities for equalisation between market values, rather than on analysing the health condition of the natural ecosystems on which the very health of the inhabitants depends.

description: We demonstrate that the covariance of the algebra of quantum NC fields under quantum-deformed Poincare symmetries implies the appearence of braided algebra of fields and the notion of braided locality in NC QFT. We briefly recall the historical development of NC QFT which was firstly formulated in the framework using classical relativistic symmetries but further it was described as generated by the quantum-deformed symmetries. We argue that consistent covariant quantum-deformed formalism requires "braiding all the way", in particular braided commutator of deformed field oscillators as well as the braid between the field oscillators and noncommutative Fourier exponentials. As example of braided quantum-deformed NC QFT we describe the NC scalar free fields on noncommutative canonical (Moyal-Weyl) space-time with braided c-number field commutator which implies braided locality.
