description: Is it possible to abstract a formal mechanism originating schisms and governing the size evolution of social conversations? In this work a constructive solution to such problem is proposed: an abstract model of a generic N-party turn-taking conversation. The model develops from simple yet realistic assumptions derived from experimental evidence, abstracts from conversation content and semantics while including topological information, and is driven by stochastic dynamics. We find that a single mechanism - namely the dynamics of conversational party's individual fitness, as related to conversation size - controls the development of the self-organized schisming phenomenon. Potential generalizations of the model - including individual traits and preferences, memory effects and more elaborated conversational topologies - may find important applications also in other fields of research, where dynamically-interacting and networked agents play a fundamental role.

description: Dynamical Chern-Simons (dCS) gravity has been attracting plenty of attentions due to the fact that it is a parity-violating modified theory of gravity that corresponds to a well-posed effective field theory in weak coupling approximation. In particular, a rotating black hole in dCS gravity is in contrast to the general relativistic counterparts. In this paper, we revisit the shadow of analytical rotating black hole spacetime in dCS modified gravity, based on which we study the shadow observables, discuss the constraint on the model parameters from the Event Horizon Telescope (EHT) observations, and analyze the real part of quasi-normal modes (QNMs) in the eikonal limit. In addition, we explore the deflection angle in weak gravitational field limit with the use of Gauss-Bonnet theorem. We find that the shadow related physics and the weak gravitational lensing effect are significantly influenced by the CS coupling, which could provide theoretical predictions for a future test of the dCS theory with EHT observations.

description: In this paper we refine our method for the abundance analysis of high resolution spectroscopy of the integrated light of unresolved globular clusters (GCs). This method was previously demonstrated for the analysis of old ($>$10 Gyr) Milky Way GCs. Here we extend the technique to young clusters using a training set of 9 GCs in the Large Magellanic Cloud (LMC). Depending on the signal-to-noise ratio of the data, we use 20-100 Fe lines per cluster to successfully constrain the ages of old clusters to within a $\sim$5 Gyr range, the ages of $\sim$2 Gyr clusters to a 1-2 Gyr range, and the ages of the youngest clusters (0.05-1 Gyr) to a $\sim$200 Myr range. We also demonstrate that we can measure [Fe/H] in clusters with any age less than 12 Gyrs with similar or only slightly larger uncertainties (0.1-0.25 dex) than those obtained for old Milky Way GCs (0.1 dex); the slightly larger uncertainties are due to the rapid evolution in stellar populations at these ages. In this paper, we present only Fe abundances and ages. In the next paper in this series, we present our complete analysis of the $\sim 20$ elements for which we are able to measure abundances. For several of the clusters in this sample, there are no high resolution abundances in the literature from individual member stars; our results are the first detailed chemical abundances available. The spectra used in this paper were obtained at Las Campanas with the echelle on the du Pont Telescope and with the MIKE spectrograph on the Magellan Clay Telescope.

description: Data mining focuses on discovering interesting, non-trivial and meaningful information from large datasets. Data clustering is one of the unsupervised and descriptive data mining task which group data based on similarity features and physically stored together. As a partitioning clustering method, K-means is widely used due to its simplicity and easiness of implementation. But this method has limitations such as local optimal convergence and initial point sensibility. Due to these impediments, nature inspired Swarm based algorithms such as Artificial Bee Colony Algorithm, Ant Colony Optimization, Firefly Algorithm, Bat Algorithm and etc. are used for data clustering to cope with larger datasets with lack and inconsistency of data. In some cases, those algorithms are used with traditional approaches such as K-means as hybrid approaches to produce better results. This paper reviews the performances of these new approaches and compares which is best for certain problematic situation.

Shielding efficiency and E(J) characteristics measured on large melt cast Bi-2212 hollow cylinders in axial magnetic fields

description: We show that tubes of melt cast Bi-2212 used as current leads for LTS magnets can also act as efficient magnetic shields. The magnetic screening properties under an axial DC magnetic field are characterized at several temperatures below the liquid nitrogen temperature (77 K). Two main shielding properties are studied and compared with those of Bi-2223, a material that has been considered in the past for bulk magnetic shields. The first property is related to the maximum magnetic flux density that can be screened, Blim; it is defined as the applied magnetic flux density below which the field attenuation measured at the centre of the shield exceeds 1000. For a cylinder of Bi-2212 with a wall thickness of 5 mm and a large ratio of length over radius, Blim is evaluated to 1 T at T = 10 K. This value largely exceeds the Blim value measured at the same temperature on similar tubes of Bi-2223. The second shielding property that is characterized is the dependence of Blim with respect to variations of the sweep rate of the applied field, dBapp/dt. This dependence is interpreted in terms of the power law E = Ec(J/Jc)^n and allows us to determine the exponent n of this E(J) characteristics for Bi-2212. The characterization of the magnetic field relaxation involves very small values of the electric field. This gives us the opportunity to experimentally determine the E(J) law in an unexplored region of small electric fields. Combining these results with transport and AC shielding measurements, we construct a piecewise E(J) law that spans over 8 orders of magnitude of the electric field.

Mobile energy hub planning for urban communities : a life cycle thinking based framework
Creators: name: Khardenavis, Amaiya Niranjan
Publisher: name: University of British Columbia
Year: 2021

description: The current climate change targets have augmented the transition towards carbon-neutral transportation systems. Hence, electric vehicles (EVs) are viewed as the most desirable instruments to reduce the automobile industry’s dependence on fossil fuels as they can integrate energy from clean sources for transportation. The electricity grid with a high penetration of renewable energy can enable emission-free travel using state-of-the-art EVs. The extensive EV demands at peak times and increased household/workplace electricity use due to population growth have led to higher utility infrastructure investments. Further, the adoption of the smart power grid concept has seen EVs being explored as energy hubs since they can be connected to the power grid with the implementation of the vehicle to grid (V2G) concept. EVs interacting with the power grid based on scheduled demand requirements can have a significant impact on society. Cars are parked 95 percent of the time; thus, with proper design and the correct infrastructure, parked and plugged-in EVs might become mass power banks, stabilizing future electric grids. They can also power households and integrate renewable energy with storage systems. However, the successful implementation and widespread adoption of V2G presents a multi-faceted problem. Through life cycle thinking, this study explores the potential opportunities and challenges of the V2G technology and examines its technological, economic, and policy-based impacts. Accordingly, this study proposes a comprehensive framework to plan and develop mobile energy hubs considering the temporal variation of EV recharging demands. Using recharging characteristics, life cycle costs travel behaviors, and geographic data as inputs to the model, the proposed framework was applied to a city in British Columbia, Canada. The outcomes of this research would be beneficial to governments, municipalities, electric utilities, and developers to understand the dynamically changing scenario in transport electrification and make decisions on climate change mitigation programs.

description: The paper deals with Bianchi type V Universe, which has dynamical energy density. We consider Bianchi type V space-time, introducing three different skewness parameters along spatial directions to quantify the deviation of pressure from isotropy. To study the anisotropic nature of the dynamical dark energy, we assume that the skewness parameters are time dependent. It is found that the Universe achieves flatness in quintessence model. The physical behavior of the Universe has been discussed in detail.

description: Scalar, vector and tensor conserved quantities are essential tools in solving different problems in physics and complex, nonlinear differential equations in mathematics. In many guises they enter our understanding of nature: charge, lepton, baryon numbers conservation accompanied with constant energy, linear or angular total momenta and the conservation of energy-momentum/angular momentum tensors in field theories due to Noether theorem which is based on the translational and Lorentz symmetry of the Lagrangians. One of the oldest discovered conserved quantities is the Laplace-Runge-Lenz vector for the $1/r$-potential. Its different aspects have been discussed many times in the literature. But explicit generalisations to other spherically symmetric potentials are still rare. Here, we attempt to fill this gap by constructing explicit examples of a conserved vector perpendicular to the angular momentum for a class of phenomenologically relevant potentials. Hereby, we maintain the nomenclature and keep calling these constant vectors Laplace-Runge-Lenz vectors.

Chromospheric activity among fast rotating M-dwarfs in the open cluster NGC 2516
Creators: name: Jackson, R. J.

Year: 2010
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We report radial velocities (RVs), projected equatorial velocities (v sin i) and CaII triplet (CaT) chromospheric activity indices for 237 late-K to mid-M candidate members of the young open cluster NGC 2516. These stars have rotation periods between 0.1 and 15 days. Intermediate resolution spectra were obtained using the Giraffe spectrograph at the Very Large Telescope. Membership was confirmed on the basis of RVs for 210 targets. We see a marked increase in the fraction of rapidly rotators as we move to cooler spectral types. About 20 per cent of M0-M1 stars have v sin i >15km/s, increasing to 90 per cent of M4 stars. Activity indices derived from the first two lines of the CaT (8498A and 8542A) show differing dependencies on rotation period and mass for stars lying above and below the fully convective boundary. Higher mass stars, of spectral type K3-M2.5, show chromospheric activity which increases with decreasing Rossby number (the ratio of period to convective turnover time), saturating for Rossby numbers <0.1. For cooler stars, which are probably fully convective and almost all of which have Rossby numbers <0.1, there is a clear decrease in chromospheric activity as (V-I)_0 increases, amounting to a fall of about a factor of 2-3 between spectral types M2.5 and M4. This decrease in activity levels at low Rossby numbers is not seen in X-ray observations of the coronae of cluster M-dwarfs or of active field M-dwarfs. There is no evidence for supersaturation of chromospheric activity for stars of any spectral type at Rossby numbers <0.01. We suggest that the fall in the limiting level of chromospheric emission beyond spectral type M3 in NGC~2516 is, like the simultaneous increase in rotation rates in field stars, associated with a change in the global magnetic topology as stars approach the fully convective boundary and not due to any decrease in dynamo-generated magnetic flux.

description: Important information about the infrared dynamics of QCD is encoded in the behavior of its (of-shell) Green's functions, most notably the gluon and the ghost propagators. Due to recent improvements in the quality of lattice data and the truncation schemes employed for the Schwinger-Dyson equations we have now reached a point where the interplay between these two non-perturbative tools can be most fruitful. In this talk several of the above points will be reviewed, with particular emphasis on the implications for the ghost sector, the non-perturbative effective charge of QCD, and the Kugo-Ojima function.

description: We present the systematic QED treatment of the electron correlation effects on the $g$ factor of lithiumlike ions for the wide range of nuclear charge number $Z= 14$ -- $82$. The one- and two-photon exchange corrections are evaluated rigorously within the QED formalism. The electron-correlation contributions of the third and higher orders are accounted for within the Breit approximation employing the recursive perturbation theory. The calculations are performed in the framework of the extended Furry picture, i.e., with inclusion of the effective local screening potential in the zeroth-order approximation. In comparison to the previous theoretical calculations, the accuracy of the interelectronic-interaction contributions to the bound electron $g$ factor in lithiumlike ions is substantially improved.

title: Characterisation of molecular mechanisms involved in nevirapine- induced hypersensitivity
Creators: name: Cornejo Castro, Elena Maria
Publisher: name: University of Liverpool Repository
Year: 2014

description: The non-nucleoside reverse transcriptase inhibitor nevirapine (NVP) is widely used in the treatment of human immunodeficiency virus infection in many sub- Saharan countries. However, NVP-treated individuals have a 5% risk of developing hypersensitivity reactions (HSRs), ranging from maculopapular exanthema to life-threatening severe cutaneous eruptions and hepatotoxicity. A number of clinical (gender and CD4+ T cell count) as well as immunogenetic factors (MHC class I and class II alleles) have been associated with NVP hypersensitivity, but the predictive value is poor.
Gene expression analyses provide an unbiased method for determining which immune-related mechanisms are involved in the pathogenesis of NVP hypersensitivity. mRNA microarray analysis demonstrated that expression of CD177, a neutrophil specific antigen, was significantly increased in our cohort of NVP-treated patients from Malawi (p ≤ 0.001), but also after in vitro treatment of NVP-hypersensitive patients from Liverpool (p

Creation of a mathematical model to describe the dynamics of the ascent of a ball in a viscous fluid. 3. Implementation of the mathematical model in the MATLAB environment. 4. Solving problems using the developed algorithm. As a result, mathematical models of the ascent of a ball in a viscous fluid were investigated. An algorithm has been developed in the MATLAB software package for finding the coordinates of the ascent of a body. Based on the algorithm, two problems were solved.
IceCube: Neutrino Messages from GRBs

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: The mystery of where and how Nature accelerates the cosmic rays is still unresolved a century after their discovery. Gamma ray bursts (GRBs) have been proposed as one of the more plausible sources of extragalactic cosmic rays. A positive observation of neutrinos in coincidence with a GRB would identify these objects as sources of the highest-energy cosmic rays and provide invaluable information about the processes occurring inside these phenomena. Calculations show that a kilometer-scale neutrino telescope is necessary for this task. The idea of such a detector is now becoming reality as IceCube at the South Pole nears completion. The contribution reviews the status of the construction and operation of IceCube and summarize the results from searches for neutrinos from GRBs and similar phenomena with IceCube and its predecessor, AMANDA. At the end, an outline of future plans and perspectives for IceCube is given.

description: Con il seguente progetto di tesi ci si pone l’obiettivo di trovare una soluzione vantaggiosa per la gestione del magazzino di manutenzione di Helsinn, azienda leader nel settore farmaceutico. Inizialmente viene analizzato lo stato AS IS del magazzino, eseguendo analisi sulla gestione di esso, sulle aree di stoccaggio presenti e sui tools utilizzati. È così possibile determinare, tramite dei flowchart, il flusso del lavoro. Inoltre, viene eseguita una classificazione di tutti i materiali stoccati a magazzino ed un’analisi sulle diverse tipologie di intervento di manutenzione. In seguito vengono individuate tutte le criticità riscontrate durante lo studio iniziale, eseguendo così un’analisi per mettere in evidenza gli interventi più urgenti. Per eseguire ciò è stato creato un flusso di priorità basandosi sull’interazione tra di esse con i relativi KPIs. Nella fase successiva vengono riportate tutte le proposte per ridurre al minimo le criticità e per ogni soluzione vengono identificati i relativi costi che l’azienda dovrà sostenere. In conclusione è stata eseguita un’analisi sui benefici a livello economico dovuti dalle soluzioni proposte, dimostrando così, oltre ad un’ottimizzazione gestionale, anche un risparmio economico per l’azienda stessa.

description: In this work we propose a channel backscattering model in which increased carrier temperature at the top of the potential energy barrier in the channel is taken into account. This model represents an extension of a previous model by the same authors which highlighted the importance of considering the partially ballistic transport between the source contact and the top of the potential energy barrier in the channel. The increase of carrier temperature is precisely due to energy dissipation between the source contact and the top of the barrier caused by the high saturation current. To support our discussion, accurate 2D full band Monte Carlo device simulations with quantum correction have been performed in double gate nMOSFETs for different geometries (gate length down to 10 nm), biases and lattice temperatures. Including the effective carrier temperature is especially important to properly treat the high inversion regime, where previous backscattering models usually fail.

Solution of the problem of uniqueness and hermiticity of hamiltonians for Dirac particles in gravitational fields

description: The authors prove that the dynamics of spin 1/2 particles in stationary gravitational fields can be described using an approach, which builds upon the formalism of pseudo-Hermitian Hamiltonians. The proof consists in the analysis of three expressions for Hamiltonians, which are derived from the Dirac equation and describe the dynamics of spin 1/2 particles in the gravitational field of the Kerr solution. The Hamiltonians correspond to different choices of tetrad vectors and differ from each other. The differences between the Hamiltonians confirm the conclusion known from many studies that the Hamiltonians derived from the Dirac equation are non-unique. Application of standard pseudo-Hermitian quantum mechanics rules to each of these Hamiltonians produces the same Hermitian Hamiltonian. The eigenvalue spectrum of the resulting Hamiltonian is the same as that of the Hamiltonians derived from the Dirac equation with any chosen system of tetrad vectors. For description of the dynamics of spin 1/2 particles in stationary gravitational fields can be used not only the formalism of pseudo-Hermitian Hamiltonians, but also an alternative approach, which employs the Parker scalar product. The authors show that the alternative approach is equivalent to the formalism of pseudo-Hermitian Hamiltonians.

description: The evolutionary sequence for high-mass star formation starts with massive starless clumps that go on to form protostellar, young stellar objects and then compact HII regions. While there are many examples of the three later stages, the very early stages have proved to be elusive. We follow-up a sample of 110 mid-infrared dark clumps selected from the ATLASGAL catalogue with the IRAM telescope in an effort to identify a robust sample of massive starless clumps. We have used the HCO+ (1-0) and HNC (1-0) transitions to identify clumps associated with infall motion and the SiO (2-1) transition to identity outflow candidates. We have found blue asymmetric line profile in 65% of the sample, and have measured the infall velocities and mass infall rates (0.6-$36 \times 10^{-3}$ Msun/yr) for 33 of these clumps. We find a trend for the mass infall rate decreasing with an increase of bolometric luminosity to clump mass i.e. star formation within the clumps evolves. Using the SiO 2-1 line, we have identified good outflow candidates. Combining the infall and outflow tracers reveals that 67% of quiescent clumps are already undergoing gravitational collapse or are associated with star formation; these clumps provide us with our best opportunity to determined the initial conditions and study the earliest stages of massive star formation. Finally, we provide an overview of a systematic high-resolution ALMA study of quiescent clumps selected that allows us to develop a detailed understanding of earliest stages and their subsequent evolution.

description: La letteratura scientifica evidenzia la correlazione tra il costrutto del capitale psicologico e numerosi aspetti di benessere e di performance scolastica negli adolescenti. Lo scopo di questo lavoro è quello di fare una revisione sistematica della letteratura, al fine di individuare gli interventi di sviluppo del capitale psicologico che sono stati adottati finora con gli studenti di scuola secondaria. Gli studi sono stati estratti da banche dati internazionali e tra le tesi prodotte al DFA/ASP e selezionati in base a determinati criteri di inclusione e di esclusione. Questo ha portato all’individuazione di un totale di 11 lavori di ricerca. Gli studi hanno mostrato che è possibile sviluppare il capitale psicologico, in un periodo di tempo di poche settimane, sia con interventi diretti di psicologia positiva sia inserendo alcuni accorgimenti pedagogico-didattici in itinerari didattici di materia. Non si può concludere che un approccio sia da preferire rispetto agli altri. Sono stati investigati aspetti di dettaglio sul tipo di attività integrate nell’intervento che potrebbero favorire l’efficacia degli interventi. Infine, tra gli interventi analizzati, sono stati individuati alcuni esempi che è possibile introdurre in aula, con semplici adattamenti, sia durante l’insegnamento della matematica sia durante le ore di classe.

Anomalous scaling of passive scalars in rotating flows

Year: 2011
Subjects: subject: Fluid Dynamics (physics.flu-dyn)

description: We present results of direct numerical simulations of passive scalar advection and diffusion in turbulent rotating flows. Scaling laws and the development of anisotropy are studied in spectral space, and in real space using an axisymmetric decomposition of velocity and passive scalar structure functions. The passive scalar is more anisotropic than the velocity field, and its power spectrum follows a spectral law consistent with $\sim k_\perp^{-3/2}$. This scaling is explained with phenomenological arguments that consider the effect of rotation. Intermittency is characterized using scaling exponents and probability density functions of velocity and passive scalar increments. In the presence of rotation, intermittency in the velocity field decreases more noticeably than in the passive scalar. The scaling exponents show good agreement with Kraichnan's prediction for passive scalar intermittency in two-dimensions, after correcting for the observed scaling of the second order exponent.

Transnational long-term learners of Chinese as peer mentors: language socialization, online learning, and identity
Creators: name: Doherty, Liam
Publisher: name: University of British Columbia
Year: 2021

description: The “mentor/mentee” relationship in mentoring research has traditionally been constructed as hierarchical (Kroll, 2016), similar to that of “expert/novice” in the field of language socialization (Howard, 2012). Although this binary understanding has been challenged by recent work in both peer mentoring and peer language socialization, peer language mentoring in the context of foreign language learning has received less attention. At the same time, there has been as yet very little research on the L2 (additional language) peer socialization of Chinese language learners (Duff, 2014b), and of learners in digital contexts in general (Reinhardt & Thorne, 2017). To address this gap, this study takes a multiple case study approach to create a portrait of four long-term learners of Chinese, their histories and learning trajectories, and the ways in which these factors came together to shape their participation in an online peer language mentoring program with 11 other non-heritage post-secondary learners of Chinese as an Additional Language (CAL) from a variety of geolinguistic and educational backgrounds. Data include participant interviews, artifacts generated by mentors in the process of preparing activities for mentees, text-based interactions of participants on the platform itself, and a variety of multimodal materials (images and video) shared therein. A process of iterative grounded analysis was used to identify the focal cases; further analysis using customized Computer-Assisted Qualitative Data Analysis Software (CAQDAS) tools developed for the study found that they shared unique characteristics and perspectives in the mentoring context, and took on roles as mentors with the explicit intention of critically addressing structural issues they perceived as existing in formal language education generally (and CAL specifically). The results of the study show how experienced language learners who are not positioned as experts by themselves or others can nevertheless provide rich peer mentoring support for newer learners in an asynchronous online setting. The insights shared by these participants offer an opportunity for language educators to engage with the unique perspectives of an under-studied group within CAL: those non-native learners who have successfully acquired their languages as adults and used them in a variety of contexts over an extended period of time.

description: LASSO regularization is a popular regression tool to enhance the prediction accuracy of statistical models by performing variable selection through the $\ell_1$ penalty, initially formulated for the linear model and its variants. In this paper, the territory of LASSO is extended to two-layer ReLU neural networks, a fashionable and powerful nonlinear regression model. Specifically, given a neural network whose output $y$ depends only on a small subset of input $\boldsymbol{x}$, denoted by $\mathcal{S}^{\star}$, we prove that the LASSO estimator can stably reconstruct the neural network and identify $\mathcal{S}^{\star}$ when the number of samples scales logarithmically with the input dimension. This challenging regime has been well understood for linear models while barely studied for neural networks. Our theory lies in an extended Restricted Isometry Property (RIP)-based analysis framework for two-layer ReLU neural networks, which may be of independent interest to other LASSO or neural network settings. Based on the result, we advocate a neural network-based variable selection method. Experiments on simulated and real-world datasets show promising performance of the variable selection approach compared with existing techniques.
