description: Novel quantum technologies and devices place unprecedented demands on the performance of experimental components, while their widespread deployment beyond the laboratory necessitates increased robustness and fast, affordable production. We show how the use of additive manufacturing, together with mathematical optimization techniques and innovative designs, allows the production of compact, lightweight components with greatly enhanced performance. We use such components to produce a magneto-optical trap that captures $\sim 2 \times 10^8$ rubidium atoms, employing for this purpose a compact and highly stable device for spectroscopy and optical power distribution, optimized neodymium magnet arrays for magnetic field generation, and a lightweight, additively manufactured ultra-high vacuum chamber. We show how the use of additive manufacturing enables substantial weight reduction and stability enhancement, while also illustrating the transferability of our approach to experiments and devices across the quantum technology sector and beyond.

description: We employ neural networks for classification of data of the TUS fluorescence telescope, the world's first orbital detector of ultra-high energy cosmic rays. We focus on two particular types of signals in the TUS data: track-like flashes produced by cosmic ray hits of the photodetector and flashes that originated from distant lightnings. We demonstrate that even simple neural networks combined with certain conventional methods of data analysis can be highly effective in tasks of classification of data of fluorescence telescopes.

description: By means of two-dimensional contact dynamics simulations, we analyze the vibrational dynamics of a confined granular layer in response to harmonic forcing. We use irregular polygonal grains allowing for strong variability of solid fraction. The system involves a jammed state separating passive (loading) and active (unloading) states. We show that an approximate expression of the packing resistance force as a function of the displacement of the free retaining wall from the jamming position provides a good description of the dynamics. We study in detail the scaling of displacements and velocities with loading parameters. In particular, we find that, for a wide range of frequencies, the data collapse by scaling the displacements with the inverse square of frequency, the inverse of the force amplitude and the square of gravity. Interestingly, compaction occurs during the extension of the packing, followed by decompaction in the contraction phase. We show that the mean compaction rate increases linearly with frequency up to a characteristic frequency and then it declines in inverse proportion to frequency. The characteristic frequency is interpreted in terms of the time required for the relaxation of the packing through collective grain rearrangements between two equilibrium states.

description: In this paper we describe the implementation of the processes f_1 bar-f_1 H A --> 0 into the framework of SANC system. Here A stands for a photon and f_1 -- for a massless fermion whose mass is neglected everywhere besides arguments of logarithmic functions. The symbol --> 0 means that all 4-momenta flow inwards. The derived one-loop scalar form factors can be used for any cross channel after an appropriate permutation of their arguments s,t,u. We present the covariant and helicity amplitudes for all three possible cross channels. For checking of the correctness of the results first of all we observe the independence on the gauge parameters and the validity of Ward identity (external photon transversality), and, secondly, we make an extensive comparison with the other independent calculations.

description: For a $(2+1)$-dimensional reformulated SU(2) Yang-Mills theory, we compute the interaction potential within the framework of the gauge-invariant but path-dependent variables formalism. This reformulation is due to the presence of a constant gauge field condensate. Our results show that the interaction energy contains a linear term leading to the confinement of static probe charges. This result is equivalent to that of the massive Schwinger model.

On the continuation of the dual amplitude with Mandelstam analyticity off mass shell
Creators: name: Magas, V. K.
Publisher: name: arXiv
Year: 2006
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: A model for the Q^2-dependent modified dual amplitude with Mandelstam analyticity (M-DAMA) is proposed. M-DAMA preserves all the attractive properties of DAMA, such as its pole structure and Regge asymptotics, and leads to a generalized dual amplitude A(s,t,Q^2). This amplitude can be checked in the known kinematical limits, i.e. it should reduce to onshell hadronic scattering amplitude for Q^2=0 and can be related to the nuclear structure function for t=0. In such a way we complete a unified "two-dimensionally dual" picture of strong interaction. By comparing the structure function F_2, resulting from M-DAMA, with phenomenological parameterizations, we fix the Q^2-dependence in M-DAMA. In all studied regions, i.e. large and low x limits as well as for the resonance region, the results of M-DAMA are in qualitative agreement with the experiment. The new feature of the M-DAMA is the possible existence, according to vector meson dominance, of Q^2 poles in negative Q^2 region, accessible in e^+ e^- annihilation.

description: We discuss renormalization of propagator of interacting Rarita--Schwinger field. Spin-3/2 contribution after renormalization takes usual resonance form. For non-leading spin-1/2 terms we found procedure, which guarantees absence of poles in energy plane. The obtained renormalized propagator has one free parameter and is a straight generalization of the famous free propagator of Moldauer and Case. Application of this propagator for production of $Δ^{++}(1232)$ in $π^{+}\particle{p}\to π^{+}\particle{p}$ leads to good description of total cross-section and to reasonable agreement with results of partial wave analysis.

description: Proptosis is characterized by a protrusion of the eyeball due to an increase of the orbital tissue volume. To recover a normal eyeball positioning, the most frequent surgical technique (BROD technique) consists in the osteotomy of orbital walls combined with a loading on the eyeball to initiate tissue decompression. This paper proposed an experimental method to quantify the intra-operative clinical gesture in proptosis reduction, and the pilot study concerned one clinical case. The eyeball's backward displacement was measured by an optical 3D localizer and the load applied by the surgeon was simultaneously measured by a custom-made force gauge. Quasi-static stiffness of the intra-orbital content was evaluated. The average values for the whole experiment was 16 N (SD: 3 N) for the force exerted by the surgeon and 9 mm (SD: 4 mm) for the eyeball backward displacement. The averaged quasi-static stiffness of the orbital content was evaluated to 2.4 N/mm (SD: 1.2) and showed a global decrease of 45% post-operatively.

description: We consider the Gibbs representation over space-time of non-equilibrium dynamics of Hamiltonian systems defined on a lattice with local interactions. We first write the corresponding action functional as a sum of local terms, defining a local action functional. We replace the local system by a translation-invariant system whose dynamics has an identical space-time characterization. We study in details the irreversible properties of the new dynamics, define the local conductivity and show its equivalence with the Green-Kubo formula. Given the definition of the local heat conductivity and using conservation of energy, we derive the shape of the temperature profile. Next, we find an explicit formula for the non-equilibrium stationary measure of harmonic systems. Finally, we apply our scheme to various approximations of anharmonic Hamiltonian models, show how to compute their thermal conductivity and recover results confirmed in numerical simulations.

Axisymmetric magneto-plastic evolution of neutron-star crusts

Year: 2021

description: Magnetic field evolution in neutron-star crusts is driven by the Hall effect and Ohmic dissipation, for as long as the crust is sufficiently strong to absorb Maxwell stresses exerted by the field and thus make the momentum equation redundant. For the strongest neutron-star fields, however, stresses build to the point of crustal failure, at which point the standard evolution equations are no longer valid. Here, we study the evolution of the magnetic field of the crust up to and beyond crustal failure, whence the crust begins to flow plastically. We perform global axisymmetric evolutions, exploring different types of failure affecting a limited region of the crust. We find that a plastic flow does not simply suppress the Hall effect even in the regime of a low plastic viscosity, but it rather leads to non-trivial evolution -- in some cases even overreacting and enhancing the impact of the Hall effect. Its impact is more pronouced in the toroidal field, with the differences on the poloidal field being less substantial. We argue that both the nature of magnetar bursts and their spindown evolution will be affected by plastic flow, so that observations of these phenomena may help to constrain the way the crust fails.

It defines technology law as law regulating technology, outlines the goals of technology law on the basis of the opportunities and risks of technologies and outlines the legal means by which these are pursued. The dynamics of technology and the associated uncertainty about the opportunities and risks of new technologies are identified as special challenges. The various areas of law covered are arranged according to the objectives and presented in an overview, in order to finally ask the question of whether technology law can be understood as a coherent area of law.

We find that the autocorrelation function displays additive aging $C(t,t_w)=C_{st}(t)+C_{ag}(t,t_w)$, where the stationary part $C_{st}$ decays algebraically. The aging part shows anomalous scaling $C_{ag}(t,t_w)={\cal C}(h(t)/h(t_w))$, where $h(u)$ is a non-homogeneous function excluding a $t/t_w$ scaling.

Elasto-plastic deformation and flow analysis in oil sand masses
Creators: name: Srithar, Thillaikanagasabai
Publisher: name: University of British Columbia
Year: 2009

description: Prediction of stresses, deformations and fluid flow in oil sand layers are important in the design of an oil recovery process. In this study, an analytical formulation is developed to predict these responses, and implemented in both 2-dimensional and 3-dimensional finite element programs. Modelling of the deformation behaviour of the oil sand skeleton and modelling of the three-phase pore fluid behaviour are the key issues in developing the analytical procedure. The dilative nature of the dense oil sand matrix, stress paths that involve decrease in mean normal stress under constant shear stress, and loading-unloading sequences are some of the important aspects to be considered in modelling the stress-strain behaviour of the sand skeleton. Linear and nonlinear elastic models have been found incapable of handling these aspects, and an elasto-plastic model is postulated to capture the above aspects realistically. The elasto-plastic model is a double-hardening type and consists of cone and cap-type yield surfaces. The model has been verified by comparison with laboratory test results on oil sand samples under various stress paths and found to be in very good agreement. The pore fluid in oil sand comprises three phases namely, water, bitumen and gas. The effects of the individual phase components are considered and modelled through an equivalent fluid that has compressibility and hydraulic conductivity characteristics representative of the components. Compressibility of the gas phase is obtained using gas laws and the equivalent compressibility is derived by considering the individual contributions of the phase components. Equivalent hydraulic conductivity is derived from the knowledge of relative permeabilities and viscosities of the phase components. Effects of temperature changes due to steam injection are also included directly in the stress-strain relation and in the flow continuity equations. The analytical equations for the coupled stress, deformation and flow problem are solved by a finite element procedure. The finite element programs have been verified by comparing the program results with closed form solutions and laboratory test results. The finite element program has been applied to predict the responses of a hor izontal well pair in the underground test facility of Alberta Oil Sand Technology and Research Authority (AOSTRA). The results are discussed and compared with the measured responses wherever possible, and indicate the analysis gives insights into the likely behaviour in terms of stresses, deformations and flow and would be important in the successful design and operation of an oil recovery scheme.

description: This study was focused on the evaluation of the relationship of learning strategies of intermediate pupils with their acquisition of grammatical skills during the online learning modality. The research design used in this study was the descriptive correlation method of research. The respondents were the ninety (90) Grade 5 students. Further, the research findings, revealed that the high or low level of grammatical skills is just as likely to occur with the high frequency of use of learning strategies as it is with low frequency of use of learning strategies. Moreover, the findings proved the frequency of utilizing the learning strategies does not relate significantly with the grammatical skills of the pupils and that there was a significant relationship that exists between memory strategy and the grammatical skills, thus it was recommended that frequent utilization of learning strategies may be considered to improve students’ grammatical skills.

description: Coleman-de Luccia processes for AdS to AdS decays in Einstein-scalar theories are studied. Such tunnelling processes are interpreted as vev-driven holographic RG flows of a quantum field theory on de Sitter space-time. These flows do not exist for generic scalar potentials, which is the holographic formulation of the fact that gravity can act to stabilise false AdS vacua. The existence of Coleman-de Luccia tunnelling solutions in a potential with a false AdS vacuum is found to be tied to the existence of exotic RG flows in the same potential. Such flows are solutions where the flow skips possible fixed points or reverses direction in the coupling. This connection is employed to construct explicit potentials that admit Coleman-de Luccia instantons in AdS and to study the associated tunnelling solutions. Thin-walled instantons are observed to correspond to dual field theories with a parametrically large value of the dimension $Δ$ for the operator dual to the scalar field, casting doubt on the attainability of this regime in holography. From the boundary perspective, maximally symmetric instantons describe the probability of symmetry breaking of the dual QFT in de Sitter. It is argued that, even when such instantons exist, they do not imply an instability of the same theory on flat space or on $R\times S^3$.

description: The progenitors of Type Ia supernovae (SNe Ia) are debated, particularly the evolutionary state of the binary companion that donates mass to the exploding carbon-oxygen white dwarf. In previous work, we presented hydrodynamic models and optically thin radio synchrotron light-curves of SNe Ia interacting with detached, confined shells of CSM, representing CSM shaped by novae. In this work, we extend these light-curves to the optically thick regime, considering both synchrotron self-absorption and free-free absorption. We obtain simple formulae to describe the evolution of optical depth seen in the simulations, allowing optically thick light-curves to be approximated for arbitrary shell properties. We then demonstrate the use of this tool by interpreting published radio data. First, we consider the non-detection of PTF11kx - an SN Ia known to have a detached, confined shell - and find that the non-detection is consistent with current models for its CSM, and that observations at a later time would have been useful for this event. Secondly, we statistically analyze an ensemble of radio non-detections for SNe Ia with no signatures of interaction, and find that shells with masses $(10^{-4}-0.3)~M_\odot$ located $(10^{15}-10^{16})$ cm from the progenitor are currently not well constrained by radio datasets, due to their dim, rapidly-evolving light-curves.

description: The study of charge-density wave (CDW) distortions in Weyl semimetals has recently returned to the forefront, inspired by experimental interest in materials such as (TaSe4)2I. However, the interplay between collective phonon excitations and charge transport in Weyl-CDW systems has not been systematically studied. In this paper, we examine the longitudinal electromagnetic response due to collective modes in a Weyl semimetal gapped by a quasi one-dimensional charge-density wave order, using both continuum and lattice regularized models. We systematically compute the contributions of the collective modes to the linear and nonlinear optical conductivity of our models, both with and without tilting of the Weyl cones. We discover that, unlike in a single-band CDW, the gapless CDW collective mode does not contribute to the conductivity unless the Weyl cones are tilted. Going further, we show that the lowest nontrivial collective mode contribution to charge transport with untilted Weyl cones comes in the third-order conductivity, and is mediated by the gapped amplitude mode. We show that this leads to a sharply peaked third harmonic response at frequencies below the single-particle energy gap. We discuss the implications of our findings for transport experiments in Weyl-CDW systems.

Os resultados obtidos neste estudo demonstram que o contacto com o quadro interativo multimédia, conhecido pelas suas potencialidades educativas, possibilitou nas crianças o desenvolvimento da sua consciência linguística das crianças, da literacia, assim como de competências tecnológicas. Palavras-chave: Sensibilização à diversidade linguística; quadro interativo multimédia; narrativa digital; educação pré-escolar. Abstract: In our days, the linguistic and cultural diversity is reflected in every school and as an opportunity for other forms of learning, by sharing ways of living and communicating. In a society where digital technologies are a facilitator of ways of learning, we present an educational research intervention project with the aim of sensitize a pre-school children’s group to linguistic diversity, using the interactive whiteboard. The results of this study show that the contact with the interactive multimedia whiteboard, known for its educational potential, enabled children to develop linguistic awareness, literacy and technological skills.

description: Economists offer what is arguably the most internally consistent framework for sustainable development assessment, the so-called “capital approach”. To operationalise the capital approach measures of the changes in comprehensive national wealth (Genuine Savings) are required. In this paper, we present estimates of Ireland’s Genuine Savings using the updated public spending code for direction and compare our results with existing estimates in the literature. For practical sustainability assessment, no single indicator is capable of providing an all-encompassing answer, but as we demonstrate, the current monitoring of sustainable development in Ireland and across the EU lacks coherence. We suggest potential paths forward for sustainability policy and assessment that preserve the link with economic theory. We show that regardless of the viewpoint taken on sustainability the capital approach can provide guidance for a coherent assessment framework.

description: A narrativa que aqui reportamos procura descrever os processos de incorporação das TIC na educação e respetivas implicações na prática pedagógica e ambientes de aprendizagem, de uma turma de 5º ano de escolaridade com proposta de Percurso Curricular Alternativo (PCA). A investigação empírica suporte desta reflexão foi desenvolvida durante dois anos letivos, numa escola de 2º e 3º Ciclos do Funchal, em que a opção por uma metodologia qualitativa de cariz etnográfico nos levou para o terreno no papel de investigadora. Foi possível verificar que o acesso dos alunos a diferentes fontes de informação e comunicação, proporcionou o surgimento de novos cenários de aprendizagem e a otimização da construção partilhada do conhecimento a partir de processos de autonomia e colaboração. ICT and learning for a proposed Alternative Curriculum Track (ACT) Abstract The narrative that we report here tries to describe the processes of incorporation of ICT in education and its implications in the pedagogical practice and learning environments of a class in the 5th year of school with a proposed Alternative Curriculum Track (ACT). The empirical research support of this reflection was developed during two academic years, in a school of 2º and 3º Ciclos of Funchal, in which the option for an ethnographic methodology took us to the field in the role of researcher. It was possible to verify that the students' access to different sources of information and communication, provided the emergence of new learning scenarios and the optimization of knowledge construction based on autonomy and collaboration processes. Key words:ICT, Alternative Curriculum Track, Ethnography, Learning, Collaboration.

Modeling the Large Scale Structures of Astrophysical Jets in the Magnetically Dominated Limit

Subjects: subject: Astrophysics (astro-ph)

description: We suggest a new approach that could be used for modeling both the large scale behavior of astrophysical jets and the magnetically dominated explosions in astrophysics. We describe a method for modeling the injection of magnetic fields and their subsequent evolution in a regime where the free energy is magnetically dominated. The injected magnetic fields, along with their associated currents, have both poloidal and toroidal components, and they are not force free. The dynamic expansion driven by the Lorentz force of the injected fields is studied using 3-dimensional ideal magnetohydrodynamic simulations. The generic behavior of magnetic field expansion, the interactions with the background medium, and the dependence on various parameters are investigated.

Renormalized Effective Actions in Radially Symmetric Backgrounds I: Partial Wave Cutoff Method

description: The computation of the one-loop effective action in a radially symmetric background can be reduced to a sum over partial-wave contributions, each of which is the logarithm of an appropriate one-dimensional radial determinant. While these individual radial determinants can be evaluated simply and efficiently using the Gel'fand-Yaglom method, the sum over all partial-wave contributions diverges. A renormalization procedure is needed to unambiguously define the finite renormalized effective action. Here we use a combination of the Schwinger proper-time method, and a resummed uniform DeWitt expansion. This provides a more elegant technique for extracting the large partial-wave contribution, compared to the higher order radial WKB approach which had been used in previous work. We illustrate the general method with a complete analysis of the scalar one-loop effective action in a class of radially separable SU(2) Yang-Mills background fields. We also show that this method can be applied to the case where the background gauge fields have asymptotic limits appropriate to uniform field strengths, such as for example in the Minkowski solution, which describes an instanton immersed in a constant background. Detailed numerical results will be presented in a sequel.

description: We will generalize the projective model structure in the category of unbounded complexes of modules over a commutative ring to the category of unbounded complexes of quasi-coherent sheaves over the projective line. Concretely we will define a locally projective model structure in the category of complexes of quasi-coherent sheaves on the projective line. In this model structure the cofibrant objects are the dg-locally projective complexes. We also describe the fibrations of this model structure and show that the model structure is monoidal. We point out that this model structure is necessarily different from other known model structures such as the injective model structure and the locally free model structure.

description: We study the localization-delocalization transition of Floquet eigenstates in a driven fermionic chain with an incommensurate Aubry-André potential and a hopping amplitude which is varied periodically in time. Our analysis shows the presence of a mobility edge separating single-particle delocalized states from localized and multifractal states in the Floquet spectrum. Such a mobility edge does not have any counterpart in the static Aubry-André model and exists for a range of drive frequencies near the critical frequency at which the transition occurs. The presence of the mobility edge is shown to leave a distinct imprint on fermion transport in the driven chain; it also influences the Shannon entropy and the survival probability of the fermions at long times. In addition, we find the presence of CAT states in the Floquet spectrum with weights centered around a few nearby sites of the chain. This is shown to be tied to the flattening of Floquet bands over a range of quasienergies. We support our numerical studies with a semi-analytic expression for the Floquet Hamiltonian ($H_F$) computed within a Floquet perturbation theory. The eigenspectra of the perturbative $H_F$ so obtained exhibit qualitatively identical properties to the exact eigenstates of $H_F$ obtained numerically. Our results thus constitute an analytic expression of a $H_F$ whose spectrum supports multifractal and CAT states. We suggest experiments which can test our theory.
