description: Peer-to-Peer protocols currently form the most heavily used protocol class in the Internet, with BitTorrent, the most popular protocol for content distribution, as its flagship. A high number of studies and investigations have been undertaken to measure, analyse and improve the inner workings of the BitTorrent protocol. Approaches such as tracker message analysis, network probing and packet sniffing have been deployed to understand and enhance BitTorrent's internal behaviour. In this paper we present a novel approach that aims to collect, process and analyse large amounts of local peer information in BitTorrent swarms. We classify the information as periodic status information able to be monitored in real time and as verbose logging information to be used for subsequent analysis. We have designed and implemented a retrieval, storage and presentation infrastructure that enables easy analysis of BitTorrent protocol internals. Our approach can be employed both as a comparison tool, as well as a measurement system of how network characteristics and protocol implementation influence the overall BitTorrent swarm performance. We base our approach on a framework that allows easy swarm creation and control for different BitTorrent clients. With the help of a virtualized infrastructure and a client-server software layer we are able to create, command and manage large sized BitTorrent swarms. The framework allows a user to run, schedule, start, stop clients within a swarm and collect information regarding their behavior.

description: The accretion of matter onto intermediate polar White Dwarfs (IPWDs) seems to provide attractive conditions for acceleration of particles to high energies in a strongly magnetized turbulent region at the accretion disk inner radius. We consider possible acceleration of electrons and hadrons in such region and investigate their high energy radiation processes. It is concluded that accelerated electrons loose energy mainly on synchrotron process producing non-thermal X-ray emission. On the other hand, accelerated hadrons are convected onto the WD surface and interact with dense matter. As a result, high energy $γ$-rays from decay of neutral pions and secondary leptons from decay of charged pions appear. We show that GeV-TeV $γ$-rays can escape from the vicinity of the WD. Secondary leptons produce synchrotron radiation in the hard X-rays and soft $γ$-rays. As an example, we predict the X-ray and $γ$-ray emission from IPWD V1223 Sgr. Depending on the spectral index of injected particles, this high energy emission may be detected by the ${\it Fermi}$-LAT telescope and/or the future Cherenkov Telescope Array (CTA) observatory.

description: In quantum information processing, it is vital to protect the coherence of qubits in noisy environments. Dynamical decoupling (DD), which applies a sequence of flips on qubits and averages the qubit-environment coupling to zero, is a promising strategy compatible with other desired functionalities such as quantum gates. Here we review the recent progresses in theories of dynamical decoupling and experimental demonstrations. We give both semiclassical and quantum descriptions of the qubit decoherence due to coupling to noisy environments. Based on the quantum picture, a geometrical interpretation of DD is presented. The periodic Carr-Purcell-Meiboom-Gill DD and the concatenated DD are reviewed, followed by a detailed exploration of the recently developed Uhrig DD, which employs the least number of pulses in an unequally spaced sequence to suppress the qubit-environment coupling to a given order of the evolution time. Some new developments and perspectives are also discussed.

description: By using an improved approximation scheme to deal with the centrifugal (pseudo-centrifugal) term, we solve the Dirac equation for the generalized Morse potential with arbitrary spin-orbit quantum number κ. In the presence of spin and pseudospin symmetry, the analytic bound state energy eigenvalues and the associated upper- and lower-spinor components of two Dirac particles are found by using the basic concepts of the Nikiforov-Uvarov method. We study the special cases when κ=\pm1 (l=l=0, s-wave), the non-relativistic limit and the limit when α becomes zero (Kratzer potential model). The present solutions are compared with those obtained by other methods. Keywords: Dirac equation, spin symmetry, pseudospin symmetry, generalized Morse potential,

Enhanced response of current-driven coupled quantum wells

description: We have investigated the conditions necessary to achieve stronger Cherenkov-like instability of plasma waves leading to emission in the terahertz (THz) regime for semiconductor quantum wells (QWs). The surface response function is calculated for a bilayer two-dimensional electron gas (2DEG) system in the presence of a periodic spatial modulation of the equilibrium electron density. The 2DEG layers are coupled to surface plasmons arising from excitations of free carriers in the bulk region between the layers. A current is passed through one of the layers and is characterized by a drift velocity for the driven electric charge. By means of a surface response function formalism, the plasmon dispersion equation is obtained as a function of angular frequency, the in-plane wave vector and reciprocal lattice vector of the density modulation. The dispersion equation,is solved numerically in the complex frequency plane for real wave vector. It is ascertained that the imaginary part of the angular frequency is enhanced with decreasing period of modulation, and with increasing the doping density of the free carriers in the bulk medium for fixed period of the spatial modulation.
Local-scale assessment of regional conservation plans : strategies for the conservation of animals and plants in a tropical rainforest and surrounding mixed-farmland
Creators: name: Contasti, Adrienne Louise
Publisher: name: University of British Columbia
Year: 2020

description: There is an urgent need to conserve biodiversity in human-modified landscapes throughout the tropics. Animal conservation has traditionally focused on single species, but it remains unclear whether these strategies will also protect other taxa that co-occur within the ecosystem. These uncertainties can also affect plant conservation if management interventions change plant-animal interactions. I identified steps to mitigate the effects of hunting, forest product extraction, and farming on rainforest animals and plants in Suaka Margasatwa Buton Utara (SMBU) and the surrounding mixed-farmland on Buton Island, Southeast Sulawesi, Indonesia. First, I used Bayesian Network inference to assess whether protecting anoa (Bubalus spp.) habitat might also benefit other animals by modelling species co-occurrences in relation to habitat and human activities. Next, I completed a pantropical Network Meta-Analysis (NMA) to identify where controlling the foraging of granivorous mammals might reduce mortality of management-sowed seeds in human-modified forests. Finally, I used the NMA to guide an experimental assessment of how seed predation might affect the regeneration of nine plant species in the reserve and mixed-farmland. Buton macaques (Macaca ochreata) did not co-occur with anoa and were the only species to avoid human-dominated areas. The government might consider concentrating patrols in easy-to-access areas to increase the distribution of macaques throughout SMBU and the mixed-farmland. The NMA identified that granivore control could help reduce seed mortality, but which seeds to protect depended on the type of human activity that modified the forest. At SMBU, granivore control was not required in the mixed-farmland because seed predation was very low for 78% of the studied plants. Low seed losses in the mixed-farmland suggested that forest regeneration might be enhanced by increasing macaque distribution and natural seed rain throughout those areas. My approach could be used to design projects that conserve animals and plants in human-modified ecosystems. Local co-occurrence analyses can identify species that remain vulnerable to humans under conservation projects focused on other species. In data deficient situations, wide-scale evidence synthesis using NMA can help guide decision making, such as when to use granivore control, in human-modified ecosystems.

Year: 2019

description: L’intento di questo lavoro di diploma è stato quello di verificare se è possibile attivare negli allievi di seconda media una riflessione sulla motivazione e, in particolare, analizzare se è possibile trasformare la motivazione degli allievi da esterna ad interna. Per trovare una risposta a questa domanda, ho messo in atto una ricerca-azione nelle mie classi di seconda durante le lezioni di arti plastiche. Il primo passo è stato quello di discutere con gli allievi sulle loro rappresentazioni riguardo al concetto di motivazione e successivamente di definire con loro un progetto per cercare di promuovere la motivazione intrinseca. I dati raccolti e analizzati lungo il percorso svolto con gli allievi testimoniano che essi sono consapevoli delle ragioni che li motivano all’impegno nell’attività scolastica e che sono in grado di discriminare i fattori interni da quelli esterni. È possibile affermare anche che la mediazione del docente e la creazione di relazioni positive e costruttive all’interno del gruppo classe favoriscono l’attivazione della motivazione intrinseca. Questo è avvenuto coinvolgendo gli allievi in un progetto comune che ha permesso loro di assumere un ruolo significativo nel processo di apprendimento, all’interno di una comunità di pari con i quali confrontarsi in un clima costruttivo.

description: AMS-dated archaeobotanical assemblages from hearth deposits of Middle Yayoi (fourth century bce–first century ce) cultural layers of the Maenakanishi site (36°09′N, 139°24′E) in northern Saitama Prefecture demonstrate that besides rice, foxtail and broomcorn millet were the most important staple crops during the second and first centuries bce. The reliance on less demanding dry-field crops at Maenakanishi and other Early to Middle Yayoi settlements in north-western Kanto and the Central Highlands in eastern central Japan contrasts with concurrent agricultural production in western and north-eastern (Tohoku) Japan, where rice cultivation generally dominated and millets apparently played a minor role. Two factors, which likely influenced this pattern, are the uneven density distribution and the cultural heterogeneity of indigenous non-agricultural Jomon populations during the formation and spread of the Yayoi culture (tenth/fourth century bce–250 ce) brought to the Japanese islands by farmers from the Asian mainland. In western Japan the spread of rice cultivation was likely promoted by low Jomon population densities. The higher importance of foxtail and broomcorn millet at Maenakanishi may be explained by cultural influence from the northern Central Highlands. Early agricultural communities in this region appear to have preferred these newcomer crops that required less labour and organisational efforts.

description: By neglecting the relative quark momenta in the propagator term, the two-photon and two-gluon decay amplitude of heavy quarkonia states can be written as a local heavy quark field operator matrix element which could be obtained from other processes or computed with QCD sum rules technique or lattice simulation, as shown in a recent work on $η_{c,b}$ two-photon decays. In this talk, I would like to discuss a similar calculation on $P$-wave $χ_{c0,2}$ and $χ_{b0,2}$ two-photon decays. We show that the effective Lagrangian for the two-photon decays of the $P$-wave $χ_{c0,2}$ and $χ_{b0,2}$ is given by the heavy quark energy-momentum tensor local operator and its trace, the $\bar{Q}Q$ scalar density. A simple expression for $χ_{c0}$ two-photon and two-gluon decay rate in terms of the $f_{χ_{c0}}$ decay constant, similar to that of $η_{c}$ is obtained. From the existing QCD sum rules value for $f_{χ_{c0}}$, we get $5\rm\,keV$ for the $χ_{c0}$ two-photon width, somewhat larger than measurement.

description: In this paper, I review the results of 3-D evolution of the inner heliosphere over the solar cycle #23, based on observations of interplanetary scintillation (IPS) made at 327 MHz using the Ooty Radio Telescope. The large-scale features of solar wind speed and density turbulence of the current minimum are remarkably different from that of the previous cycle. The results on the solar wind density turbulence show that (1) the current solar minimum is experiencing a low level of coronal density turbulence, to a present value of ~50% lower than the previous similar phase, and (2) the scattering diameter of the corona has decreased steadily after the year 2003. The results on solar wind speed are consistent with the magnetic-field strength at the poles and the warping of heliospheric current sheet.

Year: 2019

description: Il presente Lavoro di Diploma ha l’intenzione di verificare se esiste una relazione tra il praticare una attività sportiva agonistica extrascolastica ed il benessere scolastico dell’adolescente. Più precisamente, questa ricerca mira ad investigare se gli studenti di prima, seconda e terza media che svolgono un’attività sportiva agonistica, grazie ad un transfer di situazioni vissute in questo contesto, godano di un benessere scolastico maggiore rispetto a coloro che invece praticano uno sport senza competizione o non svolgono nessuna attività nel loro tempo libero. Le loro risposte sono state raccolte attraverso un questionario, il Middle Years Development Instrument (MDI), che monitora su larga scala il benessere degli studenti in questa fascia di età, implementato da tre domande specifiche sul benessere scolastico. Si è potuto verificare che esiste una forte relazione tra lo svolgere uno sport a livello agonistico ed una miglior organizzazione dello studio, una miglior gestione dell’ansia prima di una verifica e una miglior autovalutazione. Inoltre, la ricerca a livello di benessere scolastico, inteso anche a livello di maggior empatia, felicità, autostima e benessere psichico, ha fatto emergere l’enorme importanza dello sport, indipendentemente se praticato a livello agonistico o meno, di squadra o individuale, per il benessere dello studente. Infatti, coloro che praticano uno sport hanno dimostrato di godere di un più alto livello di benessere rispetto ai compagni sedentari. Relatori: Alberto Crescentini, Luca Sciaroni.

Making home in Little Syria : gendered geographies of refugee placemaking
Creators: name: Bragg, Bronwyn
Publisher: name: University of British Columbia
Year: 2020

description: Refugee resettlement is described by the UNHCR as a ‘durable solution’ to the problem of human displacement. Resettlement is also preferred by refugee-receiving states, such as Canada, who prefer resettlement to unwanted migrant/refugee arrivals at the border. Yet, while often framed as a solution, critical scholarship increasingly recognizes the complexity of resettlement as it is experienced by refugees. This dissertation picks up on this theme to understand how one group of refugee women make sense of being resettled. The central question guiding this work is: How have refugee mothers created their worlds and made meaning for themselves? This dissertation draws on 18 months of ethnographic fieldwork with Syrian refugee families living in a spatially concentrated community in an economically marginalized and socially stigmatized neighbourhood in one Canadian city. In taking an ethnographically informed, geographically specific approach to understanding refugee resettlement, this dissertation makes the following three arguments: First, processes of refugee resettlement and ‘integration’ need to be geographically informed and take seriously the relations that exist between migrants and non-migrants. I argue that in attending to what Miraftab (2016) calls a “relational sense of place,” we deepen our conceptual understandings of integration to include relations and encounters that are not visible through other methods. This includes understanding the decision-making processes, priorities and agency that refugees bring to where they choose to live. Second, by centering the experiences of refugee women, this research explores the powerful ways migrants make meaning and build lives for themselves and their families even in the wake of violence and dislocation. Syrian refugee mothers find comfort and continuity in their role as mothers and caregivers, while also struggling under the double burden of providing care to relatives overseas and learning how to navigate the work of mothering, as racialized minorities, in Canada. Finally, from the perspective of refugee mothers, resettlement is best understood as a strategy, rather than a solution (Hyndman & Giles, 2017). While human security is largely assured through resettlement, the radical disjunctures caused by ongoing restrictions on mobility and the dramatic reorganization of family life opens up new forms of precarity and displacement.

description: We use quasi-simultaneous near-infrared (near-IR) and optical spectroscopy from four observing runs to study the continuum around 1 micron in 23 well-known broad-emission line active galactic nuclei (AGN). We show that, after correcting the optical spectra for host galaxy light, the AGN continuum around this wavelength can be approximated by the sum of mainly two emission components, a hot dust blackbody and an accretion disc. The accretion disc spectrum appears to dominate the flux at ~1 micron, which allows us to derive a relation for estimating AGN black hole masses based on the near-IR virial product. This result also means that a near-IR reverberation programme can determine the AGN state independent of simultaneous optical spectroscopy. On average we derive hot dust blackbody temperatures of ~1400 K, a value close to the sublimation temperature of silicate dust grains, and relatively low hot dust covering factors of ~7%. Our preliminary variability studies indicate that in most sources the hot dust emission responds to changes in the accretion disc flux with the expected time lag, however, a few sources show a behaviour that can be attributed to dust destruction.

The psychological impact of early pregnancy events: its extent and determinants
Creators: name: Farren, Jessica Alice
Publisher: name: Imperial College London

description: Early pregnancy losses (EPLs) are ubiquitous, and a major part of healthcare provision in both primary and secondary care. However, their potential to precipitate psychological sequelae is not routinely acknowledged as part of the narrative of clinical care. This thesis summarises historical evidence that consistently demonstrates an association with anxiety, depression and posttraumatic stress disorder (PTSD). That such evidence has not significantly changed practice to date may reflect the small size of the studies, their methodological limitations, and their publication in lower impact journals targeted at a diverse range of specialists (psychologists, gynaecologists and GPs). There is a clear gap in the literature regarding the impact on women with ectopic pregnancy, and evidence needs updating to reflect modern society and clinical practice. Novel research, performed for the purposes of this PhD, involving web-based screening questionnaires, confirms a significant association with anxiety, depression and PTSD in a large group of women following EPL. The adjusted odds ratio of meeting criteria for anxiety and depression one month after loss compared to women in a healthy pregnancy was 2.14 and 3.88 respectively. Of particular note is the very high proportion of women with symptoms suggestive of PTSD (29% at 1 month, 21% at 3 months, and 18% at 9 months). Partners demonstrate significantly lower prevalence of all three disorders. Novel research also suggests that psychological morbidity in women after EPL cannot reliably be predicted by pre-existing or pregnancy-related factors, though appears more likely in women with a history of previous losses or psychiatric illness. In conclusion, in view of the potential for EPL to precipitate severe psychological sequelae, known to be associated with huge personal and societal costs, an urgent priority must be to increase awareness and recognition of these conditions, and to facilitate prompt and efficiacious treatment.

description: We have analyzed the $D\rightarrow πK, KK$ decay with the naive factorization (NF), QCD factorization (QCDF)and QCD factorization including soft-gluon exchanges (QCDF+SGE). In these decay channels, the soft-gluon effects are firstly calculated with light cone QCD sum rules. Comparing the three kind approaches, we can find the calculation results have made much more improved QCD factorization (QCDF) than the naive factorization (NF), and the calculation results have also made improved QCD factorization including soft-gluon exchanges (QCDF+SGE) than the QCD factorization (QCDF) in the color-suppressed decay channels. In addition, we find the soft-gluon effects are larger than the leading order contributions, and the calculation results are close to the experimental data for the color-suppressed decay channels. In color-allowed decay channel $D^{0}\rightarrow π^{+} K^{-}$, the soft-gluon effects are small and we should consider other power terms, such as final state interaction and annihilation effects.

description: Introduction: There is a need to continue primary healthcare services through digital communication for disadvantaged women living in underdeveloped areas of Pakistan, especially in the age of the coronavirus pandemic, social distancing and lockdown of communities. This project will be the first of its kind in aiming to implement a digital health literacy intervention, using smartphone and internet, to disadvantaged women through female community healthcare workers. Improved health literacy in women of reproductive years is known to promote maternal, child and family health overall. Methods and analysis: The study will include a baseline survey, a pre- and post-test survey and a 3-month lasting intervention on (1) hygiene and prevention and (2) coronavirus awareness and prevention. Women of reproductive years will be sampled from disadvantaged areas across the four provinces of Pakistan (Baluchistan, Khyber Pakhtunkhwa, Punjab and Sindh), and the selection criteria will be poor, semiliterate or illiterate, belonging to underdeveloped neighbourhoods devoid of universal healthcare coverage and dependent on free primary health services. A target of 1000 women will comprise the sample, with 500 women each assigned randomly to the intervention and control groups. Analysis of variance and multivariate analysis will be used for analysing the intervention's effects compared with the control group. Ethics and dissemination: Ethics approval for this study has been received from the Internal Review Board of the Forman Christian College University (reference number: IRB-252/06-2020). Results will be published in academic journals of repute and dissemination to the international scientific community and stakeholders will also be planned through workshops.

description: A subtracted dispersive representation of the $Kπ$ vector form factor, $F_+^{Kπ}$, is used to fit the Belle spectrum of $\tauKpi$ decays incorporating constraints from results on $K_{l3}$ decays. Through the use of three subtractions, the slope and curvature of $F_+^{Kπ}$ are obtained directly from the data yielding $λ_+'=(25.49 \pm 0.31) \times 10^{-3}$ and $λ_+"= (12.22 \pm 0.14) \times 10^{-4}$. The phase-space integrals relevant for $K_{l3}$ analyses are calculated. Additionally, from the pole position on the second Riemann sheet the mass and width of the $K^*(892)^\pm$ are found to be $m_{K^*(892)^\pm}= 892.0\pm 0.5$ MeV and $Γ_{K^*(892)^\pm}= 46.5 \pm 1.1$ MeV. Finally, we study the $P$-wave isospin-1/2 $Kπ$ phase-shift and its threshold parameters.

description: We describe deep, new, wide-field radio continuum observations of the Great Observatories Origins Deep Survey -- North (GOODS-N) field. The resulting map has a synthesized beamsize of ~1.7" and an r.m.s. noise level of ~3.9uJy/bm near its center and ~8uJy/bm at 15', from phase center. We have cataloged 1,230 discrete radio emitters, within a 40' x 40' region, above a 5-sigma detection threshold of ~20uJy at the field center. New techniques, pioneered by Owen & Morrison (2008), have enabled us to achieve a dynamic range of 6800:1 in a field that has significantly strong confusing sources. We compare the 1.4-GHz (20-cm) source counts with those from other published radio surveys. Our differential counts are nearly Euclidean below 100uJy with a median source diameter of ~1.2". This adds to the evidence presented by Owen & Morrison (2008) that the natural confusion limit may lie near ~1uJy. If the Euclidean slope of the counts continues down to the natural confusion limit as an extrapolation of our log N - log S, this indicates that the cutoff must be fairly sharp below 1uJy else the cosmic microwave background temperature would increase above 2.7K at 1.4 GHz.

Aiutare a vedere per capire e rappresentare: come aiutare gli allievi di prima media nel disegno realistico

description: L’intento della ricerca è trovare strategie didattiche per portare l’allievo di prima media a utilizzare l’osservazione come strumento per il disegno figurativo realistico. Cosa potrebbe aiutarlo a capire meglio ciò che sta guardando? È questa la domanda cui questa ricerca vuole trovare risposta. Come prima cosa si cerca di capire con quale tipo di supporto l’allievo riuscirà ad osservare e guardare con maggiore facilità ciò che deve copiare. Questo progetto si configura come una ricerca descrittiva, basata su dati qualitativi: come modalità di ricerca è prevista una ricerca-azione. Intendo proporre tre interventi strutturati nella forma di brevi itinerari. Le proposte didattiche punteranno sul potenziamento di un comportamento analitico generato dall’atteggiamento attivo dell’allievo che utilizza l’esperienza percettiva dell’osservazione copiando una realtà presentata su tre diversi supporti: una fotografia, un disegno scientifico e un modellino in tre dimensioni. Osservando i risultati ottenuti dagli allievi e analizzando i dati raccolti grazie ai questionari, il supporto più idoneo sul quale presentare l’immagine da copiare è la fotografia. La ricerca ha anche confermato che copiare non è un’operazione naturale. Bisogna saper mettere in atto un processo osservativo e prendere tempo per esplorare l’oggetto: esigenza raramente richiesta dalla vita quotidiana della società odierna. Oggigiorno vedere è una procedura che va appresa e soprattutto insegnata. Relatore: Dario Bianchi. Materia: Visiva

description: Objectives: In coronavirus disease 2019 (COVID-19), the adaptive immune response is of considerable importance, and detailed cellular immune reactions in the hematological system of patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection are yet to be clarified. Methods: This study reports the morphological characterization of both bone marrow and spleen in 11 COVID-19 decedents with respect to findings in the peripheral blood and pulmonary SARS-CoV-2 burden. Results: In the bone marrow, activation and left shift were found in at least 55% of patients, which was mirrored by peripheral anaemia, granulocytic immaturity and multiple thromboembolic events. Signs of sepsis-acquired immunodeficiency were found in the setting of an abscess-forming superinfection of viral COVID-19 pneumonia. Furthermore, a severe B cell loss was observed in the bone marrow and/or spleen in 64% of COVID-19 patients. This was reflected by lymphocytopenia in the peripheral blood. As compared to B cell preservation, B cell loss was associated with a higher pulmonary SARS-CoV-2 burden and only a marginal decrease of of T cell counts. Conclusions: The results of this study suggest the presence of sepsis-related immunodeficiency in severe COVID-19 pneumonia with superinfection. Furthermore, our findings indicate that lymphocytopenia in COVID-19 is accompanied by B cell depletion in hematopoietic tissue, which might impede the durability of the humoral immune response to SARS-CoV-2.
