Year: 2010

description: La tesi si inscrive nel filone delle ricerche che indagano il ruolo del’involucro edilizio nell’efficienza energetica incentrando il campo di studio sul serramento. In particolare, essa investiga su nuove connessioni interdisciplinari tra gli obiettivi di innovazione tecnologica, guidata dalla spinta del rendimento energetico che ha recentemente investito il componente infisso, ed i problemi derivanti dal suo uso quotidiano che incidono notevolmente, come dimostrato dalla letteratura, sul rendimento finale dell’edificio. Il lavoro si è a tal fine, incentrato su un’indagine empirica in un contesto residenziale dei reali modelli di uso dei serramenti. A partire dai risultati provenienti dalla suddetta analisi degli usi, si sono proposte modalità innovative per includere gli usi tra i fattori che condizionano le scelte tecniche, da compiere in fase iniziale, verso quelle più appropriate. Inoltre, si danno alcune indicazioni per lo sviluppo di “nuovi” prodotti orientati ad ottimizzare le risorse in fase d’uso.

description: TURKEYCan and Genç, adult oncology nurses from Istanbul reflect on the situation lived by their colleagues and cancer patients. They point out, “Due to the high number of cases of COVID-19 admitted to the emergency room, most patients with cancer were afraid of going to the hospital and did not know where to seek support and how to act. This situation increased their fear of catching the virus in the emergency room and caused anxiety not only in patients, but also in their relatives. It was observed that many patients worried that they could not receive comprehensive healthcare during this pandemic time.”

description: X-ray scattering by multiferroic LuFe2O4 is reported. Below 320 K, superstructure reflections indicate an incommensurate charge order with propagation close to (1/3,1/3,3/2). The corresponding charge configuration, also found by electronic structure calculations as most stable, contains polar Fe/O double-layers with antiferroelectric stacking. Diffuse scattering at 360 K, with (1/3,1/3,0) propagation, indicates ferroelectric short-range correlations between neighboring double-layers. The temperature dependence of the incommensuration indicates that charge order and magnetism are coupled.

Utility of a carbon-14 bioassay for detecting selenium limitation in marine phytoplankton
Creators: name: Clifford, Peter John
Publisher: name: University of British Columbia
Year: 2010

description: A ¹⁴C primary productivity bioassay was developed to detect selenium limitation in marine phytoplankton. Addition of Na₂Se0₃ to Se-deplete cultures of Thalassiosira pseudonana stimulated carbon uptake rates by up to 40%, when uptake was expressed on a per cell volume or relative basis. Recovery from Se-starvation was verified by changes in the growth rate and morphology of T. pseudonana. Carbon uptake rates of Katodinium rotundatum, grown in nutrient enriched artificial seawater supplemented with 10⁻¹⁰ M or 10⁻⁶ M Se, were unaffected by Na₂SeO₃ additions. Since Katodinium rotundatum did not exhibit growth responses to Se additions, it was concluded that 10⁻¹⁰ M Se was sufficient for the growth of this alga, which has not displayed an obligate Se requirement. Natural phytoplankton assemblages in the Strait of Georgia were examined for Se limitation with this ¹⁴C bioassay. Relative carbon uptake rates did not change following Na₂SeO₃ addition, indicating that these assemblages were not Se-limited at the time of the study.

description: Chiral effective theory of scalar and vector diquarks is formulated according to the linear sigma model. The main application is to describe the ground and excited states of singly heavy baryons with a charm or bottom quark. Applying the potential quark model between the diquark and the heavy quark ($Q=c, b$), we construct a heavy-quark--diquark model. The spectra of the positive- and negative-parity states of $Λ_Q$, $Σ_Q$, $Ξ^{(')}_Q$ and $Ω_Q$ are obtained. The masses and interaction parameters of the effective theory are fixed partly from the lattice QCD data and also from fitting low-lying heavy baryon masses. We find that the negative parity excited states of $Ξ_Q$ (flavor $\bar{\bf 3}$) are different from those of $Λ_Q$, because of the inverse hierarchy of the pseudoscalar diquark. On the other hand, $Σ_Q, Ξ'_Q$ and $Ω_Q$ (flavor ${\bf 6}$) baryons have similar spectra. We compare our results of the heavy-quark--diquark model with experimental data as well as the quark model.

description: Hot streaks dominate the main impact of creative careers. Despite their ubiquitous nature across a wide range of creative domains, it remains unclear if there is any regularity underlying the beginning of hot streaks. Here, we develop computational methods using deep learning and network science and apply them to novel, large-scale datasets tracing the career outputs of artists, film directors, and scientists, allowing us to build high-dimensional representations of the artworks, films, and scientific publications they produce. By examining individuals' career trajectories within the underlying creative space, we find that across all three domains, individuals tend to explore diverse styles or topics before their hot streak, but become notably more focused in what they work on after the hot streak begins. Crucially, we find that hot streaks are associated with neither exploration nor exploitation behavior in isolation, but a particular sequence of exploration followed by exploitation, where the transition from exploration to exploitation closely traces the onset of a hot streak. Overall, these results unveil among the first identifiable regularity underlying the onset of hot streaks, which appears universal across diverse creative domains, suggesting that a sequential view of creative strategies that balances experimentation and implementation may be particularly powerful for producing long-lasting contributions, which may have broad implications for identifying and nurturing creative talents.
Ein Ansatz zur dynamischen Charakterisierung und Bewertung von nichtlinearen Schwingungssystemen anhand des Beispiels Fliehkraftpendel = An approach for dynamic characterization and evaluation of nonlinear vibration systems using the example of a centrifugal pendulum absorber

description: Fliehkraftpendelsysteme zählen aufgrund ihrer kompakten Bauweise und effizienten Schwingungsreduzierung zu den bewährten Komponenten für die Reduzierung von Schwingungen in modernen Kraftfahrzeugen (Kfz). Sowohl für konventionelle, verbrennungsmotorische Systeme als auch für teil-elektrifizierte Hybridantriebe haben die schwingungsreduzierenden Maßnahmen in der Antriebsstrangentwicklung eine zunehmende Bedeutung zur Erfüllung von Komfortzielen bezüglich der Geräusche und Vibrationen im Fahrzeuginnenraum. Besonders der immer kleiner werdende Bauraum für die Systeme zur Schwingungsreduzierung erfordert eine stetige Weiterentwicklung des vielseitig einsetzbaren Fliehkraftpendels (FKP). Für die zielgerechte Optimierung von FKP-Systemen hinsichtlich ihrer schwingungsreduzierenden Eigenschaften bedarf es neben der Abstimmung der FKP-Ordnung an das jeweilige Gesamtsystem sowie der Gestaltung von wesentlichen Funktionsparametern zur Speicherung der Schwingungsenergie aus dem Antriebsstrang, insbesondere das Wissen über das dynamische Systemverhalten. Nichtlineare Effekte im FKP-Rückstellmoment reduzieren mit steigender Pendelauslenkung maßgeblich das Tilgungspotential des FKP durch eine selbstinduzierte Einleitung von Schwingungen in höheren Frequenzen in das Gesamtsystem. Mit den vorhandenen Validierungswerkzeugen konnten in der Vergangenheit keine oder nur unzureichende Erkenntnisse über die gezielte Beeinflussung dieser Effekte im FKP erlangt werden. Um die bisher bekannten Validierungsansätze in der FKP-Entwicklung effizient zu unterstützen, wird in dieser Arbeit eine Methode zur dynamischen Charakterisierung und Bewertung von FKP-Systemen hinsichtlich ihres nichtlinearen Systemverhaltens entwickelt. Aufbauend auf einer umfassenden Analyse der Gestalt-Funktions-Zusammenhänge eines FKP-Systems, die Aufschluss über die Entstehungsmechanismen des nichtlinearen Systemverhaltens und deren mögliche Beeinflussung gibt, wird eine Bewertungssystematik abgeleitet. Um zusätzlich bislang nicht zugängliche FKP-Größen wie Rückstellmoment und Pendelauslenkung zu erfassen, wird eine bewährte Validierungsumgebung für FKP-Systeme modifiziert und eine Testprozedur festgelegt, um das dynamische Systemverhalten des FKP experimentell zu ermitteln. Der experimentelle Einsatz beweist schließlich die Anwendbarkeit der Methode zur Quantifizierung des nichtlinearen Wirkzusammenhangs zwischen Rückstellmoment und Pendelauslenkung. Die Forschungsergebnisse belegen, dass durch den Einsatz der erarbeiteten Bewertungsmethode schnell und effizient Erkenntnisse für zukünftige Produktgenerationen gewonnen werden können.

description: By correctly identifying the role of central extension in the centrally extended Heisenberg algebra h, we show that it is indeed possible to construct a Hopf algebraic structure on the corresponding enveloping algebra U(h) and eventually deform it through Drinfeld twist. This Hopf algebraic structure and its deformed version U^F(h) are shown to be induced from a more fundamental Hopf algebra obtained from the Schroedinger field/oscillator algebra and its deformed version, provided that the fields/oscillators are regarded as odd-elements of the super-algebra osp(1|2n). We also discuss the possible implications in the context of quantum statistics.

Metodi di verifica della Biocompatibilità nel progetto di Architettura. Un approccio integrale al Comfort
Creators: name: Buoninconti, Luca
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2010

description: La ricerca è mirata a sviluppare un metodo per eseguire la valutazione olistica del comfort, che sia atto a prendere in considerazione i numerosi agenti - stressori, fisici e psicologici - che agiscono sulle persone. Il metodo è basato su due principi innovativi: il primo scaturisce dall'osservazione che, com'è noto, il comfort è uno stato mentale, ed è quindi frutto di un complesso equilibrio che si evolve nel tempo e nello spazio a causa delle varie sensazioni, sia di carattere fisico che psicologico. In questo lavoro vengono perciò analizzati i tre tipi di comfort a mediatore energetico (visivo, uditivo e igrotermico), che vengono poi interfacciati con le caratteristiche demografiche e psicologiche dell'utenza, allo scopo di ottenere una stima del benessere che consideri il maggior numero di fattori.
Il secondo principio parte dalla considerazione che spesso i metodi e i programmi per la valutazione del comfort necessitano di grandi quantità di parametri in ingresso, il cui prelievo è complicato, tanto per la capacità tecnica e di settore che il valutatore deve possedere, quanto per l'inaccessibilità del dato stesso, e che tale prelievo dilata notevolmente i tempi di implementazione, rendendo a volte inefficace l'intero protocollo; ciò appare soprattutto controproducente quando il metodo viene usato durante la fase di progettazione preliminare, in cui non sono a disposizione tempi e risorse economiche sufficienti ad intraprendere analisi specialistiche. Eseguendo una stima olistica, è invece possibile ridurre il numero delle variabili, in quanto si può sfruttare la spiccata ridondanza dei parametri. Un approccio integrale consente così di sviluppare metodi e strumenti in grado di ridurre quantità e qualità dei dati richiesti, semplificando ed abbreviando notevolmente le procedure di valutazione.
Viene dunque in questa tesi sviluppato il metodo di verifica della bio-compatibilità quale agile sussidio al lavoro dell'Architetto: le condizioni ambientali al contorno che influenzano gli utenti nella percezione del comfort sono infatti strettamente dipendenti dagli elementi tecnici che definiscono lo spazio costruito, e quindi dai materiali che li compongono, dai loro sistemi di assemblaggio, dalla loro forma e posizione relativa. La scelta tra le diverse soluzioni progettuali deve quindi essere supportata da strumenti in grado di eseguire valutazioni complesse, che consentano da un lato di ottenere stime relative ai livelli prestazionali afferenti alla bio compatibilità, ma che dall'altro sappiano orientare la progettazione verso scelte eco-sostenibili, non solo attraverso l'impiego di sistemi passivi, ma anche e soprattutto grazie all'uso di strategie generali di pianificazione (forma, orientamento, distribuzione delle funzioni).

description: The frequency distribution f(a) of semi-major axis of double and multiple systems, as well as their eccentricities and mass ratios, contain valuable fossil information about the process of star formation and the dynamical history of the systems. In order to advance in the understanding of these questions, we have made an extensive analysis of the frequency distribution f (a) for wide binaries (a>25 AU) in the various published catalogues, as well as in our own (Poveda et al., 1994; Allen et al., 2000; Poveda & Hernandez, 2003). Based upon all these studies we have established that the frequency f(a) is function of the age of the system and follows Oepik's distribution f(a) ~ 1/a in the range of 100 AU < a < a[c](t), where a[c](t) is a critical semi-major axis beyond which binaries have dissociated by encounters with massive objects. We argue that the physics behind the distribution f(a) ~ 1/a is a process of energy relaxation, analogous to that present in stellar clusters (secular relaxation) or in spherical galaxies (violent relaxation). The frequency distribution of mass ratios in triple systems as well as the existence of runaway stars, indicate that both types of relaxation are important in the process of binary and multiple star formation.

description: We present the time evolution of the stellar metallicity for SDSS galaxies, a sample that spans five orders of magnitude in stellar mass (10^7 - 10^{12} Msun). Assuming the BC03 stellar population models, we find that more massive galaxies are more metal-rich than less massive ones at all redshifts; the mass-metallicity relation is imprinted in galaxies from the epoch of formation. For galaxies with present stellar masses > 10^{10} Msun, the time evolution of stellar metallicity is very weak, with at most 0.2-0.3 dex over a Hubble time- for this reason the mass-metallicity relation evolves little with redshift. However, for galaxies with present stellar masses < 10^{10} Msun, the evolution is significant, with metallicity increasing by more than a decade from redshift 3 to the present. By being able to recover the metallicity history, we have managed to identify the origin of a recent discrepancy between the metallicity recovered from nebular lines and absorption lines. As expected, we show that the young population dominates the former while the old population the latter. We have investigated the dependence on the stellar models used and find that older stellar population synthesis codes do not produce a clear result. Finally, we have explored the relationship between cluster environment and metallicity, and find a strong correlation in the sense that galaxies in high density regions have high metallicity.

A PID such as a Digital Object Identifier (DOI) helps researchers to increase the visibility and impact of their publications, research data, and other research outputs. This webinar, organized by AfLIA and DataCite, gives an overview of the value that PIDs provide, how researchers can start using PIDs and how organizations can register DOIs for different research outputs. In addition to speakers from DataCite, representatives from the UbuntuNet Alliance and the International Institute of Tropical Agriculture (IITA) will share their experiences of being a DataCite member.
A cooling system for s.m.a. (shape memory alloy)based on the use of peltier cells

Publisher: name: Università degli Studi di Napoli Federico II
Year: 2010

description: The aim of this thesis has been the study and the implementation of an innovative cooling system for S.M.A. (Shape Memory Alloy) material by using a Peltier cell. This system has demonstrated a consistent cooling time reduction during the application and so that the solution adopted has confirmed that it can be used for a better operability of the S.M.A. material during the cooling phase. After an accurate selection of possible cooling system to be adopted on these materials the better choice in terms of efficiency and energy consumption reduction has converged on Peltier cell design development. In this context for our research three investigation have been conducted. The first one has concerned an analytic investigation in order to understand the phenomenology and the terms involved during the heat exchange. After this study a numerical investigation through a Finite Element approach by commercial software has been carried out. Also an experimental investigation has been conducted, at the CIRA Smart Structure Laboratory, in order to verify the results obtained by the numerical prediction. The set-up with the Peltier cell used as heater and cooler of the S.M.A. has confirmed the soundness of the solution adopted. Finally, a correlation between numerical and experimental results have been presented demonstrating the validity of the obtained results through the developed investigations. This system, composed of Peltier cell has confirmed also an energy consumption reduction because the cell has been used for heating and cooling phase without additional system as resistive system (Joule effect). This project shall be also industrial involvement in a new cost cut down point of view

description: We provide a well-posedness analysis of a kinetic model for grain growth introduced by Fradkov which is based on the von Neumann-Mullins law. The model consists of an infinite number of transport equations with a tri-diagonal coupling modelling topological changes in the grain configuration. Self-consistency of this kinetic model is achieved by introducing a coupling weight which leads to a nonlinear and nonlocal system of equations. We prove existence of solutions by approximation with finite dimensional systems. Key ingredients in passing to the limit are suitable super-solutions, a bound from below on the total mass, and a tightness estimate which ensures that no mass is transported to infinity in finite time.

description: A model of the mean-field interacting boson gas trapped by a weak harmonic potential is considered by the \textit{boson random point fields} methods. We prove that in the Weak Harmonic Trap (WHT) limit there are two phases distinguished by the boson condensation and by a different behaviour of the local particle density. For chemical potentials less than a certain critical value, the resulting Random Point Field (RPF) coincides with the usual boson RPF, which corresponds to a non-interacting (ideal) boson gas. For the chemical potentials greater than the critical value, the boson RPF describes a divergent (local) density, which is due to \textit{localization} of the macroscopic number of condensed particles. Notice that it is this kind of transition that observed in experiments producing the Bose-Einstein Condensation in traps.
Trattamento chirurgico mininvasivo robot-assistito degli aneurismi viscerali: una nuova prospettiva di cura?
Creators: name: Annecchiarico, Mario
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2010

description: Introduzione:Gli aneurismi delle arterie viscerali (AAV) non sono frequenti, ma clinicamente con una notevole incidenza riportata fino al 2% (1-2). Essi sono spesso asintomatici. Il rischio di rottura, rispetto agli aneurismi aortici è molto basso, tuttavia, in regime d'urgenza il rischio di mortalità è uguale (2). Con il miglioramento della qualità e l'uso degli ultrasuoni e della tomografia computerizzata (TC), questi aneurismi sono stati  rilevati, incidentalmente, più frequentemente in corso di indagini per  altre patologie addominali (75-94%) (3). Mentre il trattamento chirurgico di aneurismi viscerali rotti o sintomatici è ben definito, il trattamento degli aneurismi asintomatici è ancora in discussione. La terapia tradizionale per questi aneurismi può essere la resezione chirurgica, la legatura, l’embolizzazione endovascolare o lo stenting (1-3).
Materiali e Metodi:Tra settembre 2007 e giugno 2010, dodici pazienti affetti da Aneurismi Arteriosi  Viscerali (VAA) sono stati sottoposti  ad una procedura mini-invasiva presso il Dipartimento di Chirurgia Generale, dell’ Ospedale Misericordia di Grosseto. Tra questi 9 pazienti erano affetti da aneurisma dell'arteria splenica (ASA) e tre pazienti da aneurisma dell'arteria renale (RAA). Tutti gli interventi sono stati eseguiti utilizzando un approccio mininvasivo robot-assistito. La possibilità di un trattamento laparoscopico robot-assistito è stato discusso con ciascun paziente prima dell’intervento ed eseguito solo dopo opportuno consenso informato. Lo strumento utilizzato è il  sistema chirurgico robotico 'da Vinci' (Intuitive Surgical Inc., Sunnyvale, Stati Uniti).
Risultati:Tutti i pazienti sottoposti ad intervento chirurgico  non hanno avuto bisogno di ricovero in terapia intensiva e dopo l’intervento hanno avuto il decorso nel reparto di degenza.Il tempo medio operatorio di tutti i pazienti è stata 224,16 ± 65,42 minuti (range 90-310). La perdita media di sangue stimata è stata di 173 ± 180,1 ml (range 000-500). Non sono state registrate  complicanze intra-operatorie. La degenza media è stata di 7,1 ± 3,9 giorni (range 3-14) e il tempo medio di ritorno ad assumere una normale alimentazione è stato di 1,66 ± 0,65 giorni (range1-3).
Discussione:La mia tesi vuole essere uno studio di fattibilità e vuole dimostrare che un trattamento laparoscopico robot-assistito di pazienti asintomatici con questa rare patologia è un'alternativa molto attraente alle strategie di trattamento classico.La tecnologia robotica permette una dissezione estremamente accurata e raffinata così come la facile esecuzione di anastomosi microvascolari. La chirurgia robotica supera  i limiti della laparoscopia e permette l'estensione di un approccio chirugico mini-invasivo in chirurgia vascolare.

 Yılmaz and collaborators describe the changes paediatric oncology nurses in Ankara, Turkey put in place to manage during early days of COVID-19. The Chief nurse mentions, “… I am still living with my sisters, and I have to be very careful when I communicate with them. At the hospital, as a team, we are taking important cautions about using PPE. I have been applying those rules at home too and when I arrive home from hospital, I act very carefully. Keeping a healthy nutrition plan in mind, we have been eating our meals separately, as I already do in the hospital, and we are spending our time separately in our personal rooms. I have had to put limitations on my social relationships because I need to protect myself, my patients, and my family.

description: Metatanais cylindricus Shiino, 1952 Figs 1, 2 Metatanais cylindricus Shiino, 1952: 24–27, figs 6–7; Larsen and Shimomura, 2007: 2. Material examined: Lectotype female (dissected on slides) (NSMT-Cr 14507), among algae and on surface of sponges and compound ascidiae, coll. Sakata and Toshima, Seto, 9–12 May, 1948. Diagnosis: Body three times as long as wide. Carapace shorter than wide. Antennule article 1 more than twice as long as wide. Pereopod 4–6 propodus slim (about five times as long as wide), with small setae ventrally. Remarks: Metatanais cylindricus was described from 23 specimens found in shallow water off Seto (north-western coast of Japan) among aggregation of sponges and ascidiae, and catalogued as syntypes at the National Museum of Nature and Science in Tokyo. From this collection we have been loaned only one specimen which we have here designated the lectotype. It was partially dissected and drawn. In the original species description Shiino stated that specimens studied by him were females as “Neither rudimental oostegites nor mare genital papillae …” were discovered. Based on the present knowledge about the tanaid life history we can assume that Shiino has deal with both sexes, where males had the rudimental pleopods (Shiino, 1952: 26, fig 7M), and females lacked them, as loaned lectotype. M. cylindricus is morphologically almost identical to M. bipunctatus sp. n. It can be distinguished from the new species by most compact body, with cephalothorax clearly shorter than its length (Fig 1). The antennule article 1 in M. cylindricus is almost three times as long as wide and ‘columnar’ according to Shiino (1952), while it seems to be more robust and just less than twice as long as wide in the new species (Fig 2A). The species also has much slimmer propodus in pereopod of the last three pairs (over four times as long as wide).

description: The staid subject of exact static spherically symmetric perfect fluid solutions of Einstein's equations has been reinvigorated in the last decade. We now have several solution generating techniques which give rise to new exact solutions. Here the Einstein static Universe is transformed into a physically acceptable solution the properties of which are examined in detail. The emphasis here is on the importance of the integration constants that these generating techniques introduce.

POLITICHE AMBIENTALI EUROPEE E PERMESSI TRASFERIBILI DI INQUINAMENTO

description: Il presente lavoro di ricerca bibliografica, è suddiviso in quattro capitoli che analizzano, progressivamente, l’evoluzione della politica ambientale sia in ambito internazionale (dalla Conferenza di Stoccolma del 1972, alla più recente Conferenza di Copenagen del 2009 il cui obiettivo è stato quello di istituire un trattato vincolante sul clima, auspicando la sua entrata in vigore entro il 2012, quando il Protocollo di Kyoto scadrà.), che in ambito europeo. L’Unione Europea,infatti, è in prima linea nella lotta ai cambiamenti climatici ponendosi la stessa obiettivi rigorosi per la riduzione del consumo energetico e delle emissioni a livello europeo.
Essa, ha posto come obiettivo prioritario del “Sesto Programma di azione per l'ambiente” il conseguimento degli obiettivi di Kyoto ed ha istituito, nel 2003, l'European Emission Trading System (EU ETS) per facilitare gli Stati membri nel raggiungere l'obiettivo di una riduzione delle emissioni pari all'8% rispetto ai livelli del 1990 nel periodo 2008-2012.
A tale meccanismo, introdotto con la Direttiva 2003/87/CE, sarà, appunto, dedicata la parte centrale della presente ricerca. Di particolare interesse è apparsa, infatti, la creazione di un mercato di scambio delle quote di emissione dei gas serra a cui partecipano i soggetti interessati, secondo regole simili a quelle vigenti nelle borse azionarie. Il concetto di base del sistema ETS è quello di implementare un mercato di quote tale da poter invogliare le aziende a migliorare le performance ambientali non solo per evitare le sanzioni relative all’eventuale sorpasso di determinate soglie di emissioni annue, ma anche per cercare di trarre un guadagno dal sistema stesso.  Dunque, a questa tematica si rivolgerà maggiormente l’attenzione, con l’obiettivo di pervenire ad un’analisi di questo sistema, di comprenderne i meccanismi di funzionamento teorico, le sue applicazioni effettive da parte delle industrie dei settori interessati, la validità di questo metodo nell’ottica della diminuzione di emissione in atmosfera dei gas serra valutandone, infine, l’efficacia e l’andamento nel tempo.

description: TURKEY
 Yılmaz and collaborators describe the changes paediatric oncology nurses in Ankara, Turkey put in place to manage during early days of COVID-19. The Chief nurse mentions, “… I am still living with my sisters, and I have to be very careful when I communicate with them. At the hospital, as a team, we are taking important cautions about using PPE. I have been applying those rules at home too and when I arrive home from hospital, I act very carefully. Keeping a healthy nutrition plan in mind, we have been eating our meals separately, as I already do in the hospital, and we are spending our time separately in our personal rooms. I have had to put limitations on my social relationships because I need to protect myself, my patients, and my family.

description: IRAQ
 An anonymous nurse from Iraq (translated by O. Abdullah) explained the situation in Mosul, a city that has seen its share of conflict and tragedy in recent years. He states, “As an oncology nurse, the COVID-19 pandemic has put me under pressure and caused worries, especially that the patients with cancer receiving chemotherapy will suffer from symptoms that mimic COVID-19 symptoms, such as fatigue, body ache, fever, and disturbance of vital signs. The COVID-19 pandemic has affected medical and non-medical staff at our hospital mainly psychologically and physically. The dread of the disease and precautions in managing patients has increased the stress of work.”

Origins of the Combinatorial Basis of Entropy

Publisher: name: arXiv
Year: 2007
Subjects: subject: Classical Physics (physics.class-ph)
subject: FOS: Physical sciences

description: The combinatorial basis of entropy, given by Boltzmann, can be written $H = N^{-1} \ln \mathbb{W}$, where $H$ is the dimensionless entropy, $N$ is the number of entities and $\mathbb{W}$ is number of ways in which a given realization of a system can occur (its statistical weight). This can be broadened to give generalized combinatorial (or probabilistic) definitions of entropy and cross-entropy: $H=κ(ϕ(\mathbb{W}) +C)$ and $D=-κ(ϕ(\mathbb{P}) +C)$, where $\mathbb{P}$ is the probability of a given realization, $ϕ$ is a convenient transformation function, $κ$ is a scaling parameter and $C$ an arbitrary constant. If $\mathbb{W}$ or $\mathbb{P}$ satisfy the multinomial weight or distribution, then using $ϕ(\cdot)=\ln(\cdot)$ and $κ=N^{-1}$, $H$ and $D$ asymptotically converge to the Shannon and Kullback-Leibler functions. In general, however, $\mathbb{W}$ or $\mathbb{P}$ need not be multinomial, nor may they approach an asymptotic limit. In such cases, the entropy or cross-entropy function can be {\it defined} so that its extremization ("MaxEnt'' or "MinXEnt"), subject to the constraints, gives the ``most probable'' (``MaxProb'') realization of the system. This gives a probabilistic basis for MaxEnt and MinXEnt, independent of any information-theoretic justification. This work examines the origins of the governing distribution $\mathbb{P}$....

Models and Algorithms for Fairness and Priority in Scheduling
Creators: name: Bianco, Alessandro
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2010

description: In this thesis we address the problem of fair and priority scheduling. We focus our attention on systems characterized by an infinite computation, a discrete decomposition of tasks into atomic operation and a known-a-priori set of precedence-constraints among the activities to be performed. We analyze two fairness and two priority specifications related to the frequency of occurrence of activities. We solve the scheduling problem both when the scheduler has complete control upon the system's execution and when the environment can influence the outcome of a scheduling plan.
Mathematical modelling and non-linear analysis of Synthetic Gene Regulatory Networks

description: The emerging discipline of Synthetic biology can be defined as the engineering of biology. The usefulness of a model in Synthetic biology lies in its ability to formalise the knowledge about the biological process at hand, to
identify inconsistencies between hypotheses and observations, and to predict the behaviour of the biological process in yet untested conditions. The aim
must be to develop holistic models which capture the essence of various interactions within the system and are able to analyse and give predictions of the system as a whole. From this perspective, the theory of dynamical
systems and control can have a fundamental role in the analysis, modelling and design of synthetic biological circuits.

Helical and topological phase detection based on nonlocal conductance measurements in a three terminal junction

description: The helical state is a fundamental prerequisite for many spintronics applications and Majorana zero mode engineering in nanoscopic semiconductors. Its existence in quasi-one-dimensional nanowires was predicted to be detectable as a characteristic reentrant behavior in the conductance, which in a typical two-terminal architecture may be difficult to distinguish from other possible phenomena such as Fabry-Perot oscillations. Here we present an alternative method of helical gap detection free of the mentioned ambiguity, and based on the nonlocal conductance measurements in a three-terminal junction. We find that the interplay between the spin-orbit coupling and the perpendicular magnetic field leads to a spin-dependent trajectory of electrons and as a consequence a preferential injection of electrons in one of the arms. This causes a remarkable enhancement of nonlocal conductance in the helical gap regime. We show that this phenomenon can be also used to detect the topological superconducting phase when the junction is partially proximitized by an s-wave superconductor.

description: We study magnetoresistivity oscillations in a high-mobility two-dimensional electron system subject to both microwave and dc electric fields. First, we observe that the oscillation amplitude is a periodic function of the inverse magnetic field and is strongly suppressed at microwave frequencies near half-integers of the cyclotron frequency. Second, we obtain a complete set of conditions for the differential resistivity extrema and saddle points. These findings indicate the importance of scattering without microwave absorption and a special role played by microwave-induced scattering events antiparallel to the electric field.

description: We investigate how in complex systems the eigenpairs of the matrices derived from the correlations of multichannel observations reflect the cluster structure of the underlying networks. For this we use daily return data from the NYSE and focus specifically on the spectral properties of weight W_{ij} = |C|_{ij} - δ_{ij} and diffusion matrices D_{ij} = W_{ij}/s_j- δ_{ij}, where C_{ij} is the correlation matrix and s_i = \sum_j W_{ij} the strength of node j. The eigenvalues (and corresponding eigenvectors) of the weight matrix are ranked in descending order. In accord with the earlier observations the first eigenvector stands for a measure of the market correlations. Its components are to first approximation equal to the strengths of the nodes and there is a second order, roughly linear, correction. The high ranking eigenvectors, excluding the highest ranking one, are usually assigned to market sectors and industrial branches. Our study shows that both for weight and diffusion matrices the eigenpair analysis is not capable of easily deducing the cluster structure of the network without a priori knowledge. In addition we have studied the clustering of stocks using the asset graph approach with and without spectrum based noise filtering. It turns out that asset graphs are quite insensitive to noise and there is no sharp percolation transition as a function of the ratio of bonds included, thus no natural threshold value for that ratio seems to exist. We suggest that these observations can be of use for other correlation based networks as well.

description: Using the approach of coupled wave equations, we consider spontaneous parametric down-conversion (SPDC) in the narrow-band regime and its relationship to classical nonlinear processes such as sum-frequency generation. We find simple expressions in terms of mode overlap integrals for the absolute pair production rate into single spatial modes, and simple relationships between the efficiencies of the classical and quantum processes. The results, obtained with Green function techniques, are not specific to any geometry or nonlinear crystal. The theory is applied to both degenerate and non-degenerate SPDC. We also find a time-domain expression for the correlation function between filtered signal and idler fields.
