description: We discuss soft-gluon resummation for the associated production of a single top quark and a Higgs boson ($tqH$ production) in single-particle-inclusive (1PI) kinematics. We present analytical results for the higher-order corrections and numerical results for the cross sections at LHC energies. We calculate approximate NNLO total rates, including scale dependence and uncertainties from parton distributions, as well as top-quark transverse-momentum and rapidity distributions. In all cases we find that the soft-gluon corrections are dominant and provide important contributions to the total and differential cross sections.

description:

The current essay deals with the proposal to use the song for literary education. Considering the crisis that literary education has been going through in the last decades, the song represents a possible resource which could act as a ‘bridge’ between literary education and juvenile culture. Therefore, our research aims to present the didactic validity of the song as a potential instrument for literary education, demonstrating it through an exemplification. In order to reach our goal, we must firstly define literary education and its principal aims, secondly, we should consider the song’s potentialities and thirdly, we should point out the main interactions between poetry and song and finally we can present some didactical suggestions for the analysis of the poem A las Brigadas Internacionales by Rafael Alberti that we propose in its musical version by Juan & José. The exemplification represents the students’ arrival point, as they are introduced to the poem through the song and at the end they could be able to critically analyse both the forms (written and sung) in which the poem is represented.

description:

In this article, we will explore the work of several scholars who, albeit operating in different contexts, have adopted Vygotsky’s Sociocultural Theory as a starting point for their research. First of all, Vygotsky’s work will be briefly presented; second, Barnes and Mercer’s research on L1 and cognition will be commented; third, Swain’s research in immersion contexts will be shortly outlined; finally, the CLIL environment will be explored. The fil rouge which bonds all these contributions is the belief according to which language does not just ‘carry’ information but shapes thought.

description: We investigate the quark-lepton symmetric gauge group in five dimensions, with the gauge symmetry broken by a combination of orbifold compactification of the extra dimension and the Higgs mechanism. The gauge sector of the model is investigated and contrasted with the four dimensional case. We obtain lower bounds on the mass of the exotic gauge bosons, the inverse compactification scale and the exotic leptons. Light neutrinos are obtained without requiring any scale larger than a TeV. However an ultra-violet cut-off of order $10^{11}$ GeV is required to suppress proton decay inducing non-renormalizable operators.

description: «The Greens and the Reds» is the title of a picture book which has been written and illustrated with the aim to bring students in touch with the Emotional Freedom Techniques (EFT) basic recipe. Both the story and the basic EFT recipe were presented to 88, 1st grade to 5th grade primary school students, during the spring time of 2019. Based on this particular application the story was considered to be/as an appropriate tool to be used in the Primary School, suggestions for the educational process were recorded and so were possible difficulties that had to do with the use of the basic EFT recipe in a classroom setting. The results also showed that students responded positively both to the story and to EFT and reported a reduction of the negative feelings that troubled them. Some of the students made use of the basic EFT recipe out of the school setting
Dynamical density functional theory with hydrodynamic interactions and colloids in unstable traps

Year: 2008
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: A density functional theory for colloidal dynamics is presented which includes hydrodynamic interactions between the colloidal particles. The theory is applied to the dynamics of colloidal particles in an optical trap which switches periodically in time from a stable to unstable confining potential. In the absence of hydrodynamic interactions, the resulting density breathing mode, exhibits huge oscillations in the trap center which are almost completely damped by hydrodynamic interactions. The predicted dynamical density fields are in good agreement with Brownian dynamics computer simulations.
Inference of the optical depth to reionization from low multipole temperature and polarisation Planck data

description: This paper explores methods for constructing low multipole temperature and polarisation likelihoods from maps of the cosmic microwave background anisotropies that have complex noise properties and partial sky coverage. We use Planck 2018 High Frequency Instrument (HFI) and updated SRoll2 temperature and polarisation maps to test our methods. We present three likelihood approximations based on quadratic cross spectrum estimators: (i) a variant of the simulation-based likelihood (SimBaL) techniques used in the Planck legacy papers to produce a low multipole EE likelihood; (ii) a semi-analytical likelihood approximation (momento) based on the principle of maximum entropy; (iii) a density-estimation `likelihood-free' scheme (DELFI). Approaches (ii) and (iii) can be generalised to produce low multipole joint temperature-polarisation (TTTEEE) likelihoods. We present extensive tests of these methods on simulations with realistic correlated noise. We then analyse the Planck data and confirm the robustness of our method and likelihoods on multiple inter- and intra-frequency detector set combinations of SRoll2 maps. The three likelihood techniques give consistent results and support a low value of the optical depth to reoinization, tau, from the HFI. Our best estimate of tau comes from combining the low multipole SRoll2 momento (TTTEEE) likelihood with the CamSpec high multipole likelihood and is tau = 0.0627+0.0050-0.0058. This is consistent with the SRoll2 team's determination of tau, though slightly higher by 0.5 sigma, mainly because of our joint treatment of temperature and polarisation.

The Mechanisms of Codon Reassignments in Mitochondrial Genetic Codes

description: Many cases of non-standard genetic codes are known in mitochondrial genomes. We carry out analysis of phylogeny and codon usage of organisms for which the complete mitochondrial genome is available, and we determine the most likely mechanism for codon reassignment in each case. Reassignment events can be classified according to the gain-loss framework. The gain represents the appearance of a new tRNA for the reassigned codon or the change of an existing tRNA such that it gains the ability to pair with the codon. The loss represents the deletion of a tRNA or the change in a tRNA so that it no longer translates the codon. One possible mechanism is Codon Disappearance, where the codon disappears from the genome prior to the gain and loss events. In the alternative mechanisms the codon does not disappear. In the Unassigned Codon mechanism, the loss occurs first, whereas in the Ambiguous Intermediate mechanism, the gain occurs first. Codon usage analysis gives clear evidence of cases where the codon disappeared at the point of the reassignment and also cases where it did not disappear. Codon disappearance is the probable explanation for stop to sense reassignments and a small number of reassignments of sense codons. However, the majority of sense to sense reassignments cannot be explained by codon disappearance. In the latter cases, by analysis of the presence or absence of tRNAs in the genome and of the changes in tRNA sequences, it is sometimes possible to distinguish between the Unassigned Codon and Ambiguous Intermediate mechanisms. We emphasize that not all reassignments follow the same scenario and that it is necessary to consider the details of each case carefully.

description: The 2008-2018 decade was a difficult time for Greece because of the economic crisis that directly affected its social and political context. Inevitably, the consequences of the crisis did not leave the culture sector unaffected. Through the developments in the economic and socio-political sphere, in the cultural field some trends have been emerged, which dominate the artistic creation and curatorial practice in the recent years. Art and cultural professionals share their stories, their cultural projects and their views on the trends and the course of events in Greek cultural scene. How do political and economic developments affect cultural action in Greece? Could culture be a tool for a positive impact in society? Is it possible to influence and shape the political and social consciousness of the crowd through culture?

Understanding the meaning of students’ practical experiences

Publisher: name: University of British Columbia
Year: 2008

description: This study explored the meaning of practical experiences in home economics for year seven students. The research sought to gain insight into, and a deeper, richer understanding of the meaning of practical by investigating students' perspectives and the meanings that they attribute to the practical through their actions and experiences in home economics. The research involved the students and the teacher of two classes of year seven home economics students in a small town in. British Columbia. The study was conducted over a twelve week period in the Spring of 1992. Students from both classes participated in the study by way of response journals. In addition, nine students selected from one class participated in semi-structured interviews and conversations on four occasions. The study used a phenomenological approach in order to elaborate on practical experiences as gleaned from conversations, stories told in conversation and response journal writings provided by year seven home economics students. Data was collected through guided response journal entries, audiotapes of conversations, and entries in the teacher's journal. The collected data was analysed and loosely collated into two categories; shared or similar themes, and variations or unique themes. It was through both the common and the unique themes that a sense of students’ meanings of practical experiences developed. The students' conversations, journals and stories presented a colourful collage of varied experiences and meanings of the practical which could not be reduced into a simple statement of definition. The themes did, however, speak of practical experiences as valuable and relevant assisting students in a process of "becoming." The practical from the perspective of the student is that which mediates between themselves and the adult world in their process of "becoming adult".

description: Aims: Chemical compositions and other properties of planetary nebulae around central stars of spectral types [WC], [WO], and wels are compared with those of `normal' central stars, in order to clarify the evolutionary status of each type and their interrelation. Methods: We use plasma diagnostics to derive from optical spectra the plasma parameters and chemical compositions of 48 planetary nebulae. We also reanalyze the published spectra of a sample of 167 non-WR PN. The results as well as the observational data are compared in detail with those from other studies of the objects in common. Results: The central star's spectral type is clearly correlated with electron density, temperature and excitation class of the nebula, [WC] nebulae tend to be smaller than the other types. All this corroborates the view of an evolutionary sequence from cool [WC 11] central stars inside dense, low excitation nebulae towards hot [WO 1] stars with low density, high excitation nebulae. The wels PN, however, appear to be a separate class of objects, not linked to WRPN by evolution, --abridged--

description: This study investigates the usage of various types of anchoring devices for fiber reinforced polymers (FRPs) on retrofitting of reinforced concrete structural elements. The advantages and disadvantages of fiber reinforced polymer reinforcement are initially outlined. In addition, the advantages of various anchoring devices are highlighted and it is concluded that anchoring fiber reinforced polymers onto reinforced concrete elements is a method that can delay or even prevent premature debonding of composite materials from the existing reinforced concrete surface. Various anchoring systems and devices are studied, as well as different anchor failure mechanisms are outlined. Additionally, the effectiveness of each anchoring method is checked separately and the provisions of the literature are compared with the anchoring device developed by the Laboratory for Strength of Materials and Structures of Aristotle University of Thessaloniki. The relevant regulations of three International codes (Greek Code for Structural Interventions and Retrofitting, Eurocode 8 - Part 3, ACI) are commented in order to highlight cases where the provisions of a regulation are either uncertain or conservative.

description: We investigated the prompt light curves (LCs) of long gamma-ray bursts (GRBs) from the Swift/BAT catalog. We aimed to characterize their power spectral densities (PSDs), search for quasiperiodic oscillations (QPOs), and conduct novel analyses directly in the time domain. We analyzed the PSDs using Lomb-Scargle periodograms, and searched for QPOs using wavelet scalograms. We also attempted to classify the GRBs using the Hurst exponent, $H$, and the $\mathcal{A}-\mathcal{T}$ plane. The PSDs fall into three categories: power law (PL; $P(f)\propto 1/f^β$) with index $β\in(0,2)$, PL with a non-negligible Poisson noise level (PLC) with $β\in(1,3)$, and a smoothly broken PL (SBPL; with Poisson noise level) yielding high-frequency index $β_2\in(2,6)$. The latter yields break time scales on the order of 1--100\,seconds. The PL and PLC models are broadly consistent with a fully developed turbulence, $β=5/3$. For an overwhelming majority of GRBs (93\%), $H>0.5$, implying ubiquity of the long-term memory. We find no convincing substructure in the $\mathcal{A}-\mathcal{T}$ plane. Finally, we report on 34 new QPOs: with one or more constant leading periods, as well as several chirping signals. The presence of breaks and QPOs suggests the existence of characteristic time scales that in at least some GRBs might be related to the dynamical properties of plasma trajectories in the accretion disks powering the relativistic jets.

Supermassive screwed cosmic string in dilaton gravity

description: The early Universe might have undergone phase transitions at energy scales much higher than the one corresponding to the Grand Unified Theories (GUT) scales. At these higher energy scales, the transition at which gravity separated from all other interactions; the so-called Planck era, more massive strings called supermassive cosmic strings, could have been produced, with energy of about 10^{19}GeV. The dynamics of strings formed with this energy scale cannot be described by means of the weak-field approximation, as in the standard procedure for ordinary GUT cosmic strings. As suggested by string theories, at this extreme energies, gravity may be transmitted by some kind of scalar field (usually called the {\it dilaton}) in addition to the tensor field of Einstein's theory of gravity. It is then permissible to tackle the issue regarding the dynamics of supermassive cosmic strings within this framework. With this aim we obtain the gravitational field of a supermassive screwed cosmic string in a scalar-tensor theory of gravity. We show that for the supermassive configuration exact solutions of scalar-tensor screwed cosmic strings can be found in connection with the Bogomol'nyi limit. We show that the generalization of Bogomol'nyi arguments to the Brans-Dicke theory is possible when torsion is present and we obtain an exact solution in this supermassive regime, with the dilaton solution obtained by consistency with internal constraints.

description: The optical properties of single crystal Pr_{1.85}Ce_{0.15}CuO_4 have been measured over a wide frequency range above and below the critical temperature (T_c \simeq 20 K). In the normal state the coherent part of the conductivity is described by the Drude model, from which the scattering rate just above T_c is determined to be 1/τ\simeq 80 cm^{-1}. The condition that \hbar/τ\approx 2k_B T near T_c appears to be a general result in many of the cuprate superconductors. Below T_c the formation of a superconducting energy gap is clearly visible in the reflectance, from which the gap maximum is estimated to be Δ_0 \simeq 35 cm^{-1} (4.3 meV). The ability to observe the superconducting energy gap in the optical properties favors the nonmonotonic over the monotonic description of the d-wave gap. The penetration depth for T\ll T_c is λ\simeq 2000 Å, which when taken with the estimated value for the dc conductivity just above T_c of σ_{dc} \simeq 35 \times 10^3 Ω^{-1}cm^{-1} places this material on the general scaling line for the cuprates defined by 1/λ^2 \propto σ_{dc}(T\simeq T_c) \times T_c. This result is consistent with the observation that 1/τ\approx 2Δ_0, which implies that the material is not in the clean limit.

description: In this review article we present the calculation of the splitting rate in flat space of a macroscopic fundamental string either intersecting at a generic angle a Dp-brane or lying on it. The result is then applied, in the context of the string/gauge theory correspondence, to the study of exclusive decay rates of large spin mesons into mesons. As examples, we discuss the cases of N=4 SYM with a small number of flavors, and of QCD-like theories in the quenched approximation. In the latter context, explicit analytic formulas are given for decay rates of mesons formed either by heavy quarks or by massless quarks.

This paper analyzes the data of a survey conducted by means of a student questionnaire which was aimed at opening a window onto the expectations and concerns of the real actors of CLIL on the eve of its real implementation. The questionnaire was circulated amongst numerous schools in the province of Naples but only produced 226 responses. Some of the students surveyed do not seem to be very optimistic about the possible trickle down effects of CLIL on the school system: some are aware that what actually makes a reform worth carrying out is, on the one hand, the individual teacher 's ability to impact his/her students’ learning, on the other the student's own effort to progress. Several students have expressed serious concern about the possibility that poor communicative competence can affect the assimilation of contents, ie. they are putting their finger on the sore spot of the reform: assessment of progress is still a relatively unexplored area of CLIL ​​research.

description: We analyze a discrimination problem of a single-qubit unitary gate with two candidates, where the candidates are not provided with their classical description, but their quantum sample is. More precisely, there are three unitary quantum gates -- one target and one sample for each of the two candidates -- whose classical description is unknown except for their dimension. The target gate is chosen equally among the candidates. We obtain the optimal protocol that maximizes the expected success probability, assuming the Haar distribution for the candidates. This problem is originally introduced in Hillery et al. (J. Mod. Opt. 2010), which provides a protocol achieving 7/8 in the expected success probability based on the ``unitary comparison" protocol of Andersson et al. (J. Phys. A 2003). The optimality of the protocol has been an open question since then. We prove the optimality of the comparison protocol, implying that only one of the two samples (one for each candidate) is needed to achieve an optimal discrimination. The optimization includes protocols outside the scope of quantum testers due to the dynamic ordering of the sample and target gates within a given protocol.

description: Consider the braid group $B_3=< a,b| aba=bab>$ and the nearest neighbor random walk defined by a probability $ν$ with support $\{a,a^{-1},b,b^{-1}\}$. The rate of escape of the walk is explicitly expressed in function of the unique solution of a set of eight polynomial equations of degree three over eight indeterminates. We also explicitly describe the harmonic measure of the induced random walk on $B_3$ quotiented by its center. The method and results apply, mutatis mutandis, to nearest neighbor random walks on dihedral Artin groups.

description:

t It has often been claimed that methodologies integrating the study of a foreign language with that of another non-linguistic subject (i.e. CLIL or CBI) lead to considerable advantages in both language and content learning. In order to investigate this claim in relation to postsecondary education, this paper reports an experiment in which the progress made by a group of university students who attended a CLIL-type English course was compared to that of a control group attending a traditional EFL course. The results obtained mostly confirmed the initial hypothesis that the CLIL group would outperform the control group, at least as far as more communicative skills were concerned.

Didattica dell’italiano e Sistema Italia in Camerun
Creators: name: Mazoua Megni Tchio, Vicky
Publisher: name: Università Ca’ Foscari Venezia, Italia
Year: 2015

description: Sistema Italia is the interaction between the economic, productive, political, social and cultural dimensions. It refers to the image and the values that language and culture can represent abroad. The Italian language has been taught in Cameroon for almost twenty years and has recently been introduced in local schools. This research is intended to determine whether the increase in demand for Italian in Cameroon depends on the possible values that this language can convey. The discussion of the didactic aspects and of the social marketability of Italian in view of the socio-economic situation of the country shows that the motivations that lead to the study of this language have changed over time, based on the image of Italy and consequently of its language/culture.

Electromagnetic Signatures from the Tidal Tail of a Black Hole - Neutron Star Merger

description: Black hole - neutron star (BH-NS) mergers are a major target for ground-based gravitational wave (GW) observatories. A merger can also produce an electromagnetic counterpart (a kilonova) if it ejects neutron-rich matter that assembles into heavy elements through r-process nucleosynthesis. We study the kilonova signatures of the unbound dynamical ejecta of a BH-NS merger. We take as our initial state the results from a numerical relativity simulation, and then use a general relativistic hydrodynamics code to study the evolution of the ejecta with parameterized r-process heating models. The unbound dynamical ejecta is initially a flattened, directed tidal tail largely confined to a plane. Heating from the r-process inflates the ejecta into a more spherical shape and smooths its small-scale structure, though the ejecta retains its bulk directed motion. We calculate the electromagnetic signatures using a 3D radiative transfer code and a parameterized opacity model for lanthanide-rich matter. The light curve varies with viewing angle due to two effects: asphericity results in brighter emission for orientations with larger projected areas, while Doppler boosting results in brighter emission for viewing angles more aligned with the direction of bulk motion. For typical r-process heating rates, the peak bolometric luminosity varies by a factor of $\sim 3$ with orientation while the peak in the optical bands varies by $\sim 3$ magnitudes. The spectrum is blue-shifted at viewing angles along the bulk motion, which increases the $V$-band peak magnitude to $\sim -14$ despite the lanthanide-rich composition.

Impossibility of Increasing N$\acute{\textrm{e}}$el Temperature in Zigzag Graphene Nanoribbon by Electric Field and Carrier Doping
Creators: name: Prayitno, Teguh Budi
Publisher: name: arXiv
Year: 2021
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

subject: FOS: Physical sciences

description: We investigated the dependence of N$\acute{\textrm{e}}$el temperature as a critical temperature on the electric field and hole-electron doping in the antiferromagnetically ordered zigzag graphene nanoribbon. The temperature was calculated by averaging the magnon energy in the Brillouin zone within the mean-field approximation. We employed the generalized Bloch theorem instead of the supercell approach to reduce the computational cost significantly to obtain the magnon spectrum. We showed that the N$\acute{\textrm{e}}$el temperature reduces when increasing both the electric field and the hole-electron doping, thus these treatments will never enhance the N$\acute{\textrm{e}}$el temperature.

description: In this work, we study the collapse dynamics of an inhomogeneous spherically symmetric star made of dark matter (DM) and dark energy (DE). The dark matter is taken in the form of a dust cloud while anisotropic fluid is chosen as the candidate for dark energy. It is investigated how dark energy modifies the collapsing process and is examined whether dark energy has any effect on the Cosmic Censorship Conjecture. The collapsing star is assumed to be of finite radius and the space time is divided into three distinct regions $Σ$ and $V^{\pm}$, where $Σ$ represents the boundary of the star and $V^{-}(V^{+})$ denotes the interior (exterior) of the star. The junction conditions for matching $V^{\pm}$ over $Σ$ are specified. Role of Dark energy in the formation of apparent horizon is studied and central singularity is analyzed.

description: We discuss and calculate parity conserving (PC) and parity violating (PV) geometric phases for the metastable 2S states of hydrogen and deuterium. The atoms are supposed to be subjected to slowly varying electric and magnetic fields which act as external parameters for the atoms. Geometric flux density fields are introduced which allow for an easy overview how to choose the paths in parameter space in order to obtain only PC or only PV geometric phases. The PV phases are calculated in the Standard Model of particle physics. Even if numerically they come out small they have interest of principle as a new manifestation of parity violation in atomic physics.

description: A classical double oscillator model, that includes in certain parameter limits, the standard harmonic oscillator and the inverse oscillator, is interpreted as a dynamical system. We study its essential features and make a qualitative analysis of orbits around the equilibrium points, period-doubling bifurcation, time series curves, surfaces of section and Poincare maps. An interesting outcome of our findings is the emergence of chaotic behavior when the system is confronted with a periodic force term like fcosωt.
