description: In this paper, we present a domain ontology that is suitable for adaptive e-learning environments. The ontology describes the learning objects that compose a course as well as the learners and their learning styles. We also present a multi-agent e-learning system that supports predefining and re-estimating students learning styles during the course for a better personalization. In the system, learning style of each learner can be identified automatically and dynamically. We used a new literature-based method that uses learners behaviours on learning objects as indicators for this task. The evaluation showed a high precision in detecting learning styles and in delivering learning materials. Together with the mentioned benefits, this result indicates that our e-learning system is capable for wide use.

description: We present an investigation of coherent backscattering of light that is multiple scattered by a photonic crystal by using a broad-band technique. The results significantly extend on previous backscattering measurements on photonic crystals by simultaneously accessing a large frequency and angular range. Backscatter cones around the stop gap are successfully modelled with diffusion theory for a random medium. Strong variations of the apparent mean free path and the cone enhancement are observed around the stop band. The variations of the mean free path are described by a semi-empirical three-gap model including band structure effects on the internal reflection and penetration depth. A good match between theory and experiment is obtained without the need of additional contributions of group velocity or density of states. We argue that the cone enhancement reveals additional information on directional transport properties that are otherwise averaged out in diffuse multiple scattering.

description: Sono qui edite le lettere relative a uno scambio di ambasciatori fra la Firenze di Lorenzo de’ Medici e l’Egitto mamelucco per la stipula di un trattato commerciale fra i due paesi. Sullo sfondo, vi sono anche le vicende che portarono a Roma il principe ottomano Djem, visto come prezioso ostaggio da contrapporre al sultano turco Bajazed II, in guerra con quello egiziano. In particolare, sono interessanti le sei lettere scritte dal Della Stufa al Magnifico nel corso della sua missione, quasi un’eccezione nella norma fiorentina che vede la totale assenza o quasi di dispacci diplomatici provenienti dal mondo musulmano. Le due missioni diplomatiche, che conobbero anche una lunga sosta a Napoli, furono anche l’occasione per il confronto fra le due diverse civiltà. Tutto ciò è analizzato sulla base dei dispacci diplomatici del tempo e della relazione compilata dal sacerdote che accompagnò in Egitto l’oratore fiorentino Luigi Della Stufa.

description: An active interior cloak is composed of a conformal array of radiating sources surrounding a target object. With proper configuration, this array radiates a field discontinuity which cancels out any scattering which occurs when the object is illuminated by an impinging electromagnetic wave. Unlike many other cloaking methods, an interior cloak can be completely constructed using conventional components while its active nature allows it to circumvent passivity-based constraints. This enables an interior cloak to hide an object of virtually any size, shape, and material composition as well as accommodate multiple frequencies and polarizations. Despite its potential, this approach has only been demonstrated on 2D and quasi-2D targets to date. As such, this paper presents the first 3D implementation of an interior cloak. Here, the design of a cloak array capable of hiding a conductive, circular cylinder in free-space is first presented. Cloaking performance is then validated via full-wave simulations and an experimental demonstration in which the device successfully suppresses scattering when the target is illuminated by a ridged horn antenna at 1.2 GHz.

The protection of AI-generated works under European copyright law : toward adoption of a neighbouring rights approach
Creators: name: Kucukali, Berna Tugce
Publisher: name: University of British Columbia
Year: 2022

description: Individuals today create works that outperform their qualitative and quantitative capacities, thanks to generative models such as DALL-E and Midjourney, and sometimes even win awards with these works. These intelligent technologies – incorporated by many into their creative endeavours – throw into question the boundaries of copyright law, built as it is upon human creativity. The unpredictability and autonomous behaviour of AI technologies challenge many of the traditional paradigms of legal systems. The European Union has reacted to these fractures by publishing two Proposals for the AI Act and the AI Liability Directive. The Proposals sketch out a proportionate and future-proof framework for the legal protection of these technologies; but also leave many questions with respect to copyright law unaddressed. This thesis helps to fill this legal gap by analyzing the position of AI-generated works in the EU copyright system, and in so doing, contributes to the European policy-making process. This research comprises five chapters. Chapter One begins with the introduction to the research question. Chapters Two and Three outline the relevant aspects of AI technologies and Union law, respectively. Chapter Four assesses the compatibility of a number of protection models for AI-generated works within the EU copyright system, analyzing whether these technologies can dethrone the human creator, who is at the center of this system, and discard her from the creative process. Under the European copyright system, the author stamps the works with her personal touch, the protection period is based on her life duration, and moral rights are extensions of her personality. This chapter interrogates how the ‘author’, the protagonist of copyright law, can disappear in the creative process, as well as how the concepts of ownership and neighbouring rights could correspondingly evolve. Chapter Five, finally, highlights the need for reform in the legal framework for AI-generated works. It suggests that a sui generis neighbouring right regime would provide much needed transparency and proportionality for AI-generated works, which are, in fact, already a part of copyright systems without explicit acknowledgment of the AI contribution.

description: Using low-temperature scanning tunneling spectroscopy, we map the local density of states (LDOS) of graphene quantum dots supported on Ir(111). Due to a band gap in the projected Ir band structure around the graphene K point, the electronic properties of the QDs are dominantly graphene-like. Indeed, we compare the results favorably with tight binding calculations on the honeycomb lattice based on parameters derived from density functional theory. We find that the interaction with the substrate near the edge of the island gradually opens a gap in the Dirac cone, which implies soft-wall confinement. Interestingly, this confinement results in highly symmetric wave functions. Further influences of the substrate are given by the known moir{é} potential and a 10% penetration of an Ir surface resonance

Development of mass spectrometry-based untargeted metabolomics for precision health
Creators: name: Wang, Chenjingyi
Publisher: name: University of British Columbia
Year: 2022

description: As the most recently emerged “omics”, metabolomics grabbed attention in human health studies by measuring thousands of small-molecule metabolites in a wide range of biological samples. As the downstream products in the biological pathway, metabolites are regarded as the closest link to the phenotypes. Small stimuli in the human body will cause relatively huge changes in the level of metabolites. Liquid chromatography-mass spectrometry (LC-MS) is the mainstay in metabolomics research due to its high throughput, sensitivity, and reliable analysis of metabolites. Nevertheless, two of the main challenges in LC-MS based metabolomics are 1) how to apply metabolomics in studying human health and 2) apart from commonly used biological samples, including serum, plasma, and urine, how to develop a methodology of new biological samples that can be adapted to specific human health research. To address those challenges, in Chapter 2, I integrated metabolomics with metagenomics to examine human gut health. 13-species metagenomic signature was selected by random forest machine learning and achieved high diagnostic accuracy in differentiating hepatic decompensation in NAFLD-related cirrhosis. The signature was cross-validated by metabolomics. 32 metabolites and 15 metabolites from serum and feces, respectively, were found to be significantly linked to 13-discriminatory species, suggesting that the identified discriminatory species may play important roles in the progression from compensated to decompensated cirrhosis. This multi-omics study yields new avenues for identifying novel targets for therapy and microbial biomarkers of hepatic decompensation, a worldwide human disease. In Chapter 3, I integrated plasma metabolomics and proteomics to examine the health conditions of highly trained females and males following acute, severe-intensity exercise. Metabolomic and proteomic homeostasis were substantially perturbed. Through statistical analysis, some metabolites and proteins were found to be closely linked to high-intensity exercise. This multi-omics study was a powerful tool to study molecular responses to acute exercise and provided a new insight to exercise-bolstered human health. In Chapter 4, I developed a new methodology to track skin secretion. Our high-performance workflow was readily applied to a wide range of skin metabolomics research to gain a better understanding of the molecular signatures on skin that link to human health and disease.

description: Abstract: Background: Dairy cattle movement could be a major risk factor for the spread of bovine tuberculosis (BTB) in emerging dairy belts of Ethiopia. Dairy cattle may be moved between farms over long distances, and hence understanding the route and frequency of the movements is essential to establish the pattern of spread of BTB between farms, which could ultimately help to inform policy makers to design cost effective control strategies. The objective of this study was, therefore, to investigate the network structure of dairy cattle movement and its influence on the transmission and prevalence of BTB in three emerging areas among the Ethiopian dairy belts, namely the cities of Hawassa, Gondar and Mekelle. Methods: A questionnaire survey was conducted in 278 farms to collect data on the pattern of dairy cattle movement for the last 5 years (September 2013 to August 2018). Visualization of the network structure and analysis of the relationship between the network patterns and the prevalence of BTB in these regions were made using social network analysis. Results: The cattle movement network structure display both scale free and small world properties implying local clustering with fewer farms being highly connected, at higher risk of infection, with the potential to act as super spreaders of BTB if infected. Farms having a history of cattle movements onto the herds were more likely to be affected by BTB (OR: 2.2) compared to farms not having a link history. Euclidean distance between farms and the batch size of animals moved on were positively correlated with prevalence of BTB. On the other hand, farms having one or more outgoing cattle showed a decrease on the likelihood of BTB infection (OR = 0.57) compared to farms which maintained their cattle. Conclusion: This study showed that the patterns of cattle movement and size of animal moved between farms contributed to the potential for BTB transmission. The few farms with the bulk of transmission potential could be efficiently targeted by control measures aimed at reducing the spread of BTB. The network structure described can also provide the starting point to build and estimate dynamic transmission models for BTB, and other infectious diseases.

description: In statistical physics, the conservation of particle number results in the equalization of the chemical potential throughout a system at equilibrium. In contrast, the homogeneity of utility in socio-economic models is usually thought to rely on the competition between individuals, leading to Nash equilibrium. We show that both views can be reconciled by introducing a notion of chemical potential in a wide class of socio-economic models, and by relating it in a direct way to the equilibrium value of the utility. This approach also allows the dependence of utility across the system to be determined when agents take decisions in a probabilistic way. Numerical simulations of a urban economic model also suggest that our result is valid beyond the initially considered class of solvable models.

description: Le vicende dello Studio fiorentino nel Quattrocento sono piene di luci e di ombre: periodi di grande fioritura si alternano a profonde crisi, che si riflettono invevitabilmente sulla storia della fabbrica della Sapienza, grande cantiere promosso dagli Ufficiali dello Studio nel 1429 e finanziato da Niccolò da Uzzano. La scelta del sito per edificare la Casa di Sapienza fiorentina cade in un vasto lotto, ancora inedificato, fra S. Marco e la SS. Annunziata. Lo studio analizza le vicende costruttive della fabbrica - rimasta incompiuta - e ne segue l’uso e le trasformazioni fra Quattrocento e Cinquento, portando numerosi elementi di novità su un tema che contava una scarissima letteratura; si riflette su una possibile attribuzione, presentando dei grafici che ricostruiscono l’estensione e la morfologia di massima del vastissimo complesso. Viene analizzata anche la funzione precipua dell’edificio, di cui si precisa la natura di collegio universitario e non di sede degli insegnamenti universitari, dislocatati invece nelle chiese o nella sede di via dello Studio, dietro la Cattedrale.

Gli affari di messer Palla Strozzi (e di suo padre Nofri). Imprenditoria e mecenatismo nella Firenze del primo Rinascimento

Year: 2011

description: Il saggio si propone di far luce sulle vicende economico-patrimoniali di messer Palla di Nofri Strozzi (Firenze 1372-Padova 1462), personaggio di spicco della Firenze del primo Rinascimento, sia come uomo politico ingiustamente travolto dalla purga medicea scatenata nel 1434 contro gli oppositori di Cosimo il Vecchio, sia come letterato, collezionista di codici librari, promotore degli studia humanitatis e committente di opere d’arte. Al centro di una frammentata serie di indagini da parte di storici dell’arte, della cultura e della politica, Palla Strozzi ha suscitato invece scarsa attenzione da parte degli storici dell’economia, nonostante un particolare non secondario: al catasto fiorentino del 1427 risultava essere il cittadino più ricco, ma dopo nemmeno cinque anni era già così oberato dai debiti da non riuscire più a pagare le tasse al fisco fiorentino. La vicenda di messer Palla, messa a confronto con quella del padre Nofri, infaticabile uomo d’affari capace di ammassare una gigantesca fortuna (poi parzialmente dissipata dal figlio), è analizzata nei dettagli grazie alla ricchissima serie archivistica delle carte strozziane: in particolare tramite lo spoglio di numerosi libri di conti intestati ad aziende e patrimoni di famiglia. Il confronto tra le differenti attitudini dei due personaggi fa emergere in tutta la sua originalità la figura di messer Palla: uomo coltissimo ma anche elitario, eppure dotato di un alto senso dello stato, capace di mostrare verso il denaro un’inclinazione che lo avvicina più all’aristocratico rentier dell’ancien régime e/o al raffinato signore padano del pieno rinascimento, piuttosto che al mondo dei grandi «mercatanti» che lo aveva generato.

description: We revisit the process $e^+e^- \to γZ$ at the ILC with transverse beam polarization in the presence of anomalous CP-violating $γZ Z$ coupling $λ_1$ and $γγZ$ coupling $λ_2$. We point out that if the final-state spins are resolved, then it becomes possible to fingerprint the anomalous coupling {\rm Re}$λ_1$.90% confidence level limit on {\rm Re}$λ_1$ achievable at ILC with center-of-mass energy of 500 GeV or 800 GeV with realistic initial beam polarization and integrated luminosity is of the order of few times of $10^{-2}$ when the helicity of $Z$ is used and $10^{-3}$ when the helicity of $γ$ is used. The resulting corrections at quadratic order to the cross section and its influence on these limits are also evaluated and are shown to be small. The benefits of such polarization programmes at the ILC are compared and contrasted for the process at hand. We also discuss possible methods by which one can isolate events with a definite helicity for one of the final-state particles.

description: Abstract: Background: Participants in clinical research studies often do not reflect the populations for which healthcare interventions are needed or will be used. Enhancing representation of under-served groups in clinical research is important to ensure that research findings are widely applicable. We describe a multicomponent workstream project to improve representation of under-served groups in clinical trials. Methods: The project comprised three main strands: (1) a targeted scoping review of literature to identify previous work characterising under-served groups and barriers to inclusion, (2) surveys of professional stakeholders and participant representative groups involved in research delivery to refine these initial findings and identify examples of innovation and good practice and (3) a series of workshops bringing together key stakeholders from funding, design, delivery and participant groups to reach consensus on definitions, barriers and a strategic roadmap for future work. The work was commissioned by the UK National Institute for Health Research Clinical Research Network. Output from these strands was integrated by a steering committee to generate a series of goals, workstream plans and a strategic roadmap for future development work in this area. Results: ‘Under-served groups’ was identified and agreed by the stakeholder group as the preferred term. Three-quarters of stakeholders felt that a clear definition of under-served groups did not currently exist; definition was challenging and context-specific, but exemplar groups (e.g. those with language barriers or mental illness) were identified as under-served. Barriers to successful inclusion of under-served groups could be clustered into communication between research teams and participant groups; how trials are designed and delivered, differing agendas of research teams and participant groups; and lack of trust in the research process. Four key goals for future work were identified: building long-term relationships with under-served groups, developing training resources to improve design and delivery of trials for under-served groups, developing infrastructure and systems to support this work and working with funders, regulators and other stakeholders to remove barriers to inclusion. Conclusions: The work of the INCLUDE group over the next 12 months will build on these findings by generating resources customised for different under-served groups to improve the representativeness of trial populations.
Probing boundary-corrections to Nambu-Goto open string energy levels in 3d SU(2) gauge theory

description: We measure the energy levels of the excitations of the flux tube between static quark and antiquark in three-dimensional SU(2) gauge theory. Combining exponential error reduction techniques and a variational method we are able to reduce the errors for the excited states significantly and to extract excited states in distinct parity and charge conjugation channels. It is conjectured that the infrared behavior (at large q\bar{q} separation R) of the flux tube is governed by an effective string theory. Indeed previous simulations show good agreement between lattice data and predictions from Nambu-Goto string theory. Recently, new results on the effective string theory obtained corrections to the Nambu-Goto predictions and showed that for the open string in three dimensions first corrections should appears at order 1/R^4. They correspond to boundary terms in the worldsheet field theory. These corrections are presumably small for the ground state, but significantly larger for the excited states and lift the degeneracies of the free theory. Assuming this functional form of the correction, we obtain for the coefficient b_2=-0.5(2)(2).

description: LiCu2O2 is the first multiferroic cuprate to be reported and its ferroelectricity is induced by complex magnetic ordering in ground state, which is still in controversy today. Herein, we have grown nearly untwinned LiCu2O2 single crystals of high quality and systematically investigated their dielectric and ferroelectric behaviours in external magnetic fields. The highly anisotropic response observed in different magnetic fields apparently contradicts the prevalent bc- or ab- plane cycloidal spin model. Our observations give strong evidence supporting a new helimagnetic picture in which the normal of the spin helix plane is along the diagonal of CuO4 squares which form the quasi-1D spin chains by edge-sharing. Further analysis suggests that the spin helix in the ground state is elliptical and in the intermediate state the present c-axis collinear SDW model is applicable with some appropriate modifications. In addition, our studies show that the dielectric and ferroelectric measurements could be used as probes for the characterization of the complex spin structures in multiferroic materials due to the close tie between their magnetic and electric orderings.

description: Persistent mental illness, bipolar disorder affects more than 1% of people worldwide. It causes a person's mood and energy to shift abruptly, and it also impairs their capacity to think rationally. Neurotransmitter imbalance, along with genetic and environmental factors, are the main causes of bipolar disorder. Diabetes, cardiovascular disease, and metabolic syndrome are more likely in people with bipolar disorder. In the medical world, early diagnosis is uncommon since bipolar disorder lacks biomarkers and is characterized by nonspecific symptoms or a rapid shift in mood. Suicide risk is heightened by depression, which is the major factor.
 Approximately 20 times more people commit suicide owing to bipolar disorder than the overall population, according to an SMR survey. Both nonpsychiatric and psychiatric medical specialists should be present at the same time. Lithium is reportedly frequently prescribed to lower the risk of suicide. A patient with bipolar disorder may have a wide range of symptoms, including stress, hypomania, and mania. Additionally, it has been observed that patients and their families are reluctant and unable to comprehend the significance of symptoms, particularly those of hypomania or mania. The main issue is that no study or research on bipolar disorder has been able to live. The severe to find the exact or correct treatment for bipolar disorder, leading to a treatment that is lifelong and involves a combination of medications and psychotherapy. There is also an urgent need for the right and perfect medication to treat this problem. Early diagnosis and treatment.
KEYWORDS: Stress, Suicide, Mania, Depression, Disability, and Hypomania are all symptoms of bipolar illness.

description: Abstract
Usually Composites are manufactured using synthetic Fibers; in recent times natural fibers are deployed in the manufacture of composites since they are economical, locally accessible and bio-degradable. Water absorption by these fibers and weaker bondage between matrix phase and natural fibers results in the reduction of the strength of the composites. Therefore, alkali treatment for these fibers makes modifications on its surface which improve their mechanical properties. In the present study, fabrication of 3 mm and 5 mm thick banana polyester composites is done using compression moulding process to analyse their the tensile strength parameters. Tensile strength characteristics of 5%,10% and 15% NaOH treated banana fiber polyester composites are studied. In the present study of composites, the soaking period of NaOH treatment was adapted from 3 to 15 hours. A decrease in tensile strength was observed as the soaking period was increased. The composites fabricated with 25% Fiber volume fractions with 5% of NaOH treatment for 3 hours of soaking period exhibited peak Tensile Strength. These composites are very much suitable to use as alternative Building Materials, passengers seats in railway coaches and automobile doors. ANN approach provides an alternate solution for prediction of properties by utilizing minimum of experimental data. Hence in the present study, ANN weighted matrix adopted has given good results with low error as compared to experimental results.

description: The Cherenkov effect is a well known phenomenon in the electrodynamics of fast charged particles passing through transparent media. If the particle is faster than the light in a given medium, the medium emits a forward light cone. This beautiful phenomenon has an acoustic counterpart where the role of photons is played by phonons and the role of the speed of light is played by the sound velocity. In this case the medium emits a forward sound cone. Here, we show that in a system with spin-orbit interactions in addition to this {\it normal} Cherenkov sound there appears an {\it anomalous} Cherenkov sound with forward and {\it backward} sound propagation. Furthermore, we demonstrate that the transition from the normal to anomalous Cherenkov sound happens in a {\it singular} way at the Cherenkov cone angle. The detection of this acoustic singularities therefore represents an alternative experimental tool for the measurement of the spin-orbit coupling strength.

description: We revise fundamental concepts in the dynamics of open quantum systems in the light of modern developments in the field. Our aim is to present a unified approach to the quantum evolution of open systems that incorporates the concepts and methods traditionally employed by different communities. We present in some detail the mathematical structure and the general properties of the dynamical maps underlying open system dynamics. We also discuss the microscopic derivation of dynamical equations, including both Markovian and non-Markovian evolutions.

description: Polymeric materials play a key role in modern industry. Owing to outstanding and very versatile properties of polymers, they have rather quickly occupied the great niche of commodities. World plastic production is continuously growing from 1.7 Mton/year in 1950 to 288 Mton/year in 2012. Fossil sources are still required for production of the major part of polymers, as only 5% of chemicals are currently produced from renewable feedstocks. Nevertheless, the application of natural chemicals as feedstocks for the manufacture of polymers is steadily increasing. Different motivations induce such a high interest toward new biobased materials. First of all, the global depletion of petroleum resources and their uneven spread over the world stimulate the rational use of biomass as a renewable and ubiquitous resource. Additionally, overwhelming of dumps with nondegradable plastics causes serious ecological problems, stimulating the developments toward new biodegradable materials. Here we have to point at the distinction between the terms “biobased” and “biodegradable”. Biobased products are manufactured from renewable sources, but several examples of biobased and nonbiodegradable products, e.g., biopolyethylene, biopolyamide 11, exist. It should be noted that each new material has to be tested for biodegradability before it can be claimed to be so. For example, linear polymers produced from itaconic acid are biodegradable, but cross-linking of the polymer chains slows down the biodegradation

description: Le persecuzioni antiebraiche a Firenze dopo l’8 settembre 1943 furono par- ticolarmente cruente. Malgrado l’efficacia e l’estensione di una rete protettiva di aiuti, la convinta collaborazione delle istituzioni locali della Repubblica Sociale Italiana con gli occupanti tedeschi impresse alle persecuzioni un’impronta particolare di violenza ed accanimento, che portò all’arresto, seguito da deportazione ad Auschwitz, di più di trecento ebrei, italiani e stranieri, presenti in città. Nel periodo immediatamente successivo alla liberazione, con la guerra ancora in corso, a Firenze gli ebrei scampati, frastornati, spogliati dei loro beni, ancora inconsapevoli della catastrofe ebraica europea e della fine toccata ai loro cari deportati, furono invitati dal Comitato Toscano di Liberazione Nazionale e dalla Comunità ebraica a compilare memoriali sulle sofferenze subite. Oggi quegli scritti costituiscono un significativo corpus documentario che testimonia di una memoria collettiva ebraica in fase di formazione ancora al di qua della frattura della Shoah, capace di raccontare vicende e afflizioni percepite poi come ‘minori’, una volta realizzata l’entità del disastro. Emergono anche da queste precoci testimonianze, da cui sono tratti i due documenti che qui si pubblicano, speranze concrete di ottenere giustizia e di vedere puniti i colpevoli, che con l’avanzare del difficile dopoguerra italiano andranno poi invece deluse.
