description: Envolto em polémica e controvérsia, o Novo Acordo Ortográfico ainda não reúne consenso entre os membros da Comunidade de Países de Língua Portuguesa (CPLP). Tendo em conta este cenário, apresentamos um estudo de caso de natureza qualitativa, que partiu da análise de 12 entrevistas (vídeos do site Youtube e notícias do jornal online “O País”),a falantes de Língua Portuguesa de Portugal, Brasil e Moçambique, a fim de identificar quais os tópicos do documento oficial do Acordo Ortográfico que suscitam mais preocupação, bem como compreender quais os motivos para a resistência ao Acordo de 1990. Inspirado num paradigma interpretativo, o estudo revelou-nos que a posição dos Sujeitos brasileiros, relativamente aos pontos do documento oficial, divergem em relação aos pontos defendidos por portugueses e moçambicanos. Adicionalmente, a análise comparativa ajudou-nos a organizar os argumentos dos falantes em várias dimensões, permitindo assim compreender que as razões de cada país para a resistência ao Acordo têm motivos muito variados.

description: We show how the flat spacetime Galileon field theories (FSGFT) in arbitrary dimensions can be obtained through a Born-Infeld type structure. This construction involves a brane metric and non-linear combinations of derivatives of a scalar field. Our setup gives rise to some Galileon tensors and vectors useful for the variational analysis which are related to the momentum density of the probe Lovelock branes floating in a $N$-dimensional flat bulk. We find further that the Noether currents associated to these Galileon theories may be written in terms of such tensors.

description: Ken Robinson ganhou visibilidade junto do público com as suas ideias sobre educação e criatividade, sendo amplamente conhecido o seu livro “O Elemento”, traduzido em 21 países, assim como a sua participação em 2006 e 2010 nas conferências TED. Destaca-se a discordância com o atual sistema educativo, por considerar que este não potencia, antes destrói, a criatividade e os talentos naturais das crianças. Contextualizámos este estudo na literatura sobre as teorias contemporâneas da educação, referindo ainda dois exemplos de aplicação de ideias próximas do autor: a escola Summerhill (de Neill) e as escolas de Reggio Emilia. Aplicando uma metodologia qualitativa e enquadrando-se no paradigma interpretativo de um estudo de caso, tentámos identificar algumas teorias da educação implícitas no discurso de Ken Robinson no livro e na conferência “O Elemento” e relacioná-las com os comentários do público que assistiu à conferência no YouTube™. Os resultados obtidos mostram que a maioria dos comentários são positivos e concordantes com as ideias sustentadas pelo orador, evidenciando igualmente admiração pelas suas competências de comunicador. Embora o seu discurso aponte críticas ao sistema educativo, defendendo, na senda de outros autores, que deveria ser mais “personalista”, não torna claro que modelo de sistema educativo e que mecanismos viabilizariam uma educação mais personalizada.

description: We generalize the results for Banach algebras of pseudodifferential operators obtained by Gröchenig and Rzeszotnik in [24] to quasi-algebras of Fourier integral operators. Namely, we introduce quasi-Banach algebras of symbol classes for Fourier integral operators that we call generalized metaplectic operators, including pseudodifferential operators. This terminology stems from the pioneering work on Wiener algebras of Fourier integral operators [11], which we generalize to our framework. This theory finds applications in the study of evolution equations such as the Cauchy problem for the Schrödinger equation with bounded perturbations, cf. [7].

description: Com base nas potencialidades da comunicação interativa e descentralizada na Internet, a disponibilização crescente de espaços destinados aos comentários dos “leitores” na imprensa online tem suscitado o debate em torno do seu contributo para a inversão da tendência descendente, evidenciada pela atual sociedade, no exercício de uma cidadania ativa. Atendendo a este fenómeno, o presente artigo pretende analisar e discutir, adotando como referencia a teoria deliberativa, as evidencias desta possibilidade nos comentários feitos na secção de Educação pelos “leitores” do jornal Publico.pt. Suportados em técnicas de análise de conteúdo a um corpus de 294 comentários referentes a 9 notícias da secção e jornal referidos, os resultados sugerem que embora os comentadores não tenham a intenção de alcançarem consenso no debate com os demais, estão interessados em expressar e partilhar as suas opiniões, argumentos e pontos de vista, mesmo que o façam sob anonimato. A analise aos comentários permitiu concluir que a deliberação que se verificou neste espaço do Publico.pt assumiu um carater essencialmente publico e coletivo, na medida em que os comentadores debatem na esfera públicos problemas comuns, embora não se verifique a transformação das opiniões dos participantes no debate por forca dos argumentos de outros que a deliberação pressupõe.

description: The interaction between cells of the epidermis and the basal lamina is important for the integrity of the skin. Several hereditary and acquired diseases show changes at the dermal-epidermal interface due to loss of adhesion between basal cells and the basement membrane. The structures mediating this interaction are hemidesmosomes, which have been extensively characterized by biochemical, molecular biologic, and morphologic techniques. Recently, however, a group of adhesion molecules that are distinct from hemidesmosomes and that mediate cell-matrix interactions was described in cultured fibroblasts, keratinocytes, and skin. These adhesion molecules, β1 integrins, have been shown to be present in the focal adhesion, a cell-matrix contact associated with microfilaments rather than intermediate filaments characteristic of hemidesmosomes. In cultured cells, integrins of the β1 family have been shown to be linked by a protein complex to actin filaments. In this study we describe the localization of talin, the binding protein for β1 integrins, and vinculin at the dermal-epidermal interface in skin with immunofluorescence and immunoblotting techniques. These data suggest the presence of a link between the cytoplasmic actin filament system in basal keratinocytes and the extracellular matrix.

description: We compute the non-factorisable ${\cal O}(α_s^2)$ corrections to $t$-channel single-top quark production at the LHC. These peculiar corrections arise because of interactions between the heavy- and the light-quark lines and appear for the very first time at next-to-next-to-leading order in perturbative QCD. We find that the non-factorisable corrections change the single-top production cross section and the relevant kinematic distributions in this process by about half a percent.

description: Anti-52- and anti-60-kDa Ro/SS-A (Ro) autoantibodies are produced by most patients with subacute cutaneous lupus erythematosus and neonatal lupus erythematosus and are thought to be pathogenic in these two disorders. To learn more about the epidermal antigens targeted by Ro autoantibodies, a panel of anti-52 and anti-60-kDa Ro antibodies was purified from human autoimmune sera and rabbit antisera and then used to: (i) determine the expression and location of the Ro antigens in human keratinocytes; (ii) clarify discrepancies in previous localization studies; and (iii) verify the existence of Ro autoantibodies that cross-react with the 52- and 60-kDa Ro antigens, as previously reported. By immunoblot analysis these antibodies demonstrate that 52- and 60-kDa Ro proteins are expressed in normal human skin and cultured keratinocytes. By indirect immunofluorescence studies with cultured human cells, the anti-52-kDa Ro antibodies produce fine granular cytoplasmic fluorescence and less intense nuclear fluorescence, with apparent nucleolar sparing. The anti-60-kDa Ro autoantibodies produce weak cytoplasmic fluorescence and intense coarse granular nuclear fluorescence with apparent nucleolar sparing. We found distinct differences in the intracellular localization of the 52- and 60-kDa Ro autoantigens. This difference suggests that the 52-and 60-kDa Ro antigens may have independent cellular functions. Finding 60-kDa Ro antigen predominantly in the nucleus challenges the notion that the majority of the intracellular 60-kDa Ro antigen is complexed with the cytoplasmic hY RNA. Additionally, our failure to find a cross-reactive epitope on these two proteins indicates that the 52-kDa Ro antigen is probably a true immunogen and not merely a protein that cross-reacts with anti-60-kDa Ro autoantibodies, as others have suggested.

description: In this work, Na isotopes with mass varying from $A=$ 20 to 31 have been studied using DJ16A, JISP16 and N3LO microscopic effective interactions in the $sd$-shell. These effective interactions are derived for $sd$-shell using no-core shell model wavefunctions and a unitary transformation method. We have also performed calculation with IMSRG effective interactions targeted for a particular nucleus. The studies include a detailed analysis of ground state binding energy, low-lying spectra, and electromagnetic properties such as reduced electric quadrupole transition strengths, quadrupole and magnetic dipole moments of the Na chain. The results obtained from these microscopic effective interactions were compared with the experimental data as well as with the results of phenomenological interaction USDB. The charge radii of Na isotopes are evaluated using shell model harmonic oscillator wave functions. In addition to charge radii, matter radii and neutron skin thickness in the Na chain are discussed with a focus on neutron-deficient Na isotopes.

description: Spectroscopic techniques are very essential tools in studying electronic structures, spectroscopic constants and energetic properties of diatomic molecules. These techniques are also required for parametrization of new method based on theoretical analysis and computational calculations. In this research, we apply the proper quantization rule in spectroscopic study of some diatomic molecules by solving the Schrödinger equation with two solvable quantum molecular systems-Tietz-Wei and shifted Deng-Fan potential models for their approximate nonrelativistic energy states via an appropriate approximation to the centrifugal term. We show that the energy levels can be determined from its ground state energy. The beauty and simplicity of the method applied in this study is that, it can be applied to any exactly as well as approximately solvable models. The validity and accuracy of the method is tested with previous techniques via numerical computation for H$_2$ and CO diatomic molecules. The result also include energy spectrum of 5 different electronic states of NO and 2 different electronic state of ICl.

description: Understanding how proteins fold into their native structure is a fundamental problem in biophysics, crucial for protein design. It has been hypothesized that the formation of a molten globule intermediate precedes folding to the native conformation of globular proteins; however, its thermodynamic properties are poorly known. We perform single-molecule pulling experiments of protein barnase in the range of 7$^\circ$C to 37$^\circ$C using a temperature-jump optical trap. We derive the folding free energy, entropy and enthalpy, and heat capacity change ($ΔC_p = 1050\pm50$ cal/mol$\cdot$K) at low ionic strength conditions. From the measured unfolding and folding kinetic rates, we also determine the thermodynamic properties of the transition state, finding a significant change in $ΔC_p$ ($\sim$ 90$\%$) between the unfolded and the transition states. In contrast, the major change in enthalpy ($\sim$ 80$\%$) occurs between the transition and native states. These results highlight a transition state of high energy and low configurational entropy structurally similar to the native state, in agreement with the molten globule hypothesis.

description: High-throughput density functional theory (DFT) calculations allow for a systematic search for conventional superconductors. With the recent interest in two-dimensional (2D) superconductors, we used a high-throughput workflow to screen over 1,000 2D materials in the JARVIS-DFT database and performed electron-phonon coupling calculations, using the McMillan-Allen-Dynes formula to calculate the superconducting transition temperature ($T_c$) for 165 of them. Of these 165 materials, we identify 34 dynamically stable structures with transition temperatures above 5 K, including materials such as W$_2$N$_3$, NbO$_2$, ZrBrO, TiClO, NaSn$_2$S$_4$, Mg$_2$B$_4$C$_2$ and the previously unreported Mg$_2$B$_4$N$_2$ ($T_c$ = 21.8 K). Finally, we performed experiments to determine the $T_c$ of selected layered superconductors (2H-NbSe$_2$, 2H-NbS$_2$, ZrSiS, FeSe) and discuss the measured results within the context of our DFT results. We aim that the outcome of this workflow can guide future computational and experimental studies of new and emerging 2D superconductors by providing a roadmap of high-throughput DFT data.

description: The temperature dependence of the latency of an optical signal transmitted over an optical fiber was investigated by means of a correlation OTDR. While the bare fiber showed a linear latency increase over temperature, the jumper cable inside a jacket with tight buffer as inner jacket showed an increased elongation effect, especially in the range of lower tempera-tures. This could be attributed to the tight buffer. For future latency sensitive applications in the area of 5G networks these effects have to be taken into account.

description: We compute scaling solutions of functional flow equations for quantum gravity in a general truncation with up to four derivatives of the metric. They connect the asymptotically free ultraviolet fixed point, which is accessible to perturbation theory, to the non-perturbative infrared region. The existence of such scaling solutions is necessary for a renormalizable quantum field theory of gravity. If the proposed scaling solution is confirmed beyond our approximations asymptotic freedom is a viable alternative to asymptotic safety for quantum gravity.

description: This is the third (and the last) code in a collection of three programs [Sokolovski et al (2011), Akhmatskaya et al (2014)] dedicated to the analysis of numerical data, obtained in an accurate simulation of an atom-diatom chemical reaction. Our purpose is to provide a detailed description of a FORTRAN code for complex angular momentum (CAM) analysis of the resonance effects in reactive angular scattering [for CAM analysis of integral reactive cross sections see [Akhmatskaya et al (2014)]. The code evaluates the contributions of a Regge trajectory (or trajectories) to a differential cross section in a specified range of energies. The contribution is computed with the help of the methods described in [Dobbyn et al (2007), Sokolovski and Msezane (2004), Sokolovski et al (2007)]. Regge pole positions and residues are obtained by analytically continuing S-matrix element, calculated numerically for the physical integer values of the total angular momentum, into the complex angular momentum plane using the PADE II program [Sokolovski et al (2011)]. The code represents a reactive scattering amplitude as a sum of the components corresponding to a rapid "direct" exchange of the atom, and the various scenarios in which the reactants form long-lived intermediate complexes, able to complete several rotations before breaking up into products. The package has been successfully tested on the representative models, as well as the F + H2->HF+H benchmark reaction. Several detailed examples are given in the text. PACS:34.50.Lf,34.50.Pi

description: Combining optical gain in direct-bandgap III-V materials with tunable optical feedback offered by advanced photonic integrated circuits is key to chip-scale external-cavity lasers (ECL), offering wideband tunability along with low optical linewidths. External feedback circuits can be efficiently implemented using low-loss silicon nitride (Si$_{3}$N$_{4}$) waveguides, which do not suffer from two-photon absorption and can thus handle much higher power levels than conventional silicon photonics. However, co-integrating III-V-based gain elements with tunable external feedback circuits in chip-scale modules still represents a challenge, requiring either technologically demanding heterogeneous integration techniques or costly high-precision multi-chip assembly. In this work, we demonstrate Si$_{3}$N$_{4}$-based hybrid integrated ECL that exploit 3D-printed structures such as intra-cavity photonic wire bonds and facet-attached microlenses for low-loss optical coupling with relaxed alignment tolerances, thereby overcoming the need for active alignment while maintaining the full flexibility of multi-chip integration techniques. In a proof-of-concept experiment, we demonstrate an ECL offering a 90 nm tuning range (1480 nm - 1570 nm) with on-chip output powers above 12 dBm and side-mode suppression ratios of up to 59 dB. We achieve an intrinsic linewidth of 979 Hz, which is among the lowest values reported for comparable feedback architectures. The optical loss of the intra-cavity photonic wire bond between the III-V gain element and the Si$_{3}$N$_{4}$-based tunable feedback circuit amounts to approximately (1.6 $\pm$ 0.2) dB. We use the ECL as a tunable pump laser to generate a dissipative Kerr soliton frequency comb. To the best of our knowledge, our experiments represent the first demonstration of a single-soliton Kerr comb generated with a pump that is derived from a hybrid ECL.

description: Transient bullous dermolysis of the newborn (TBDN) is a blistering disease evident at birth or shortly thereafter, but the blistering tendency decreases with advancing age. The tissue separation in TBDN is below the lamina densa, and electron microscopy has revealed abnormalities in anchoring fibrils. Immunofluorescence staining demonstrates intracellular accumulation of type VII collagen. In this study, we report a G-to-C transversion mutation in the last nucleotide of intron 35 of the type VII collagen gene (COL7A1) in a family with autosomal dominant TBDN in three generations. This nucleotide substitution abolishes the obligatory consensus 3'-acceptor splice site, predicting in-frame skipping of exon 36. Thus, TBDN in this family is caused by a mutation in COL7A1, and is therefore allelic with other variants of dominant dystrophic epidermolysis bullosa.

description: We study the impact of an additional $U(1)'$ gauge symmetry with flavour-dependent charges for quarks and leptons on the LHC flavour anomalies observed in $B \to K^* μ^+μ^-$, $R(K) = B \to K μ^+μ^-/B \to K e^+e^-$, and $h \to μτ$. In its minimal version with two scalar doublets, the resulting model naturally explains the deviations from the Standard Model observed in $B \to K^* μ^+μ^-$ and $R(K)$. The CMS access in $h \to μτ$ can be explained by introducing a third scalar doublet, which gives rise to a prediction for $τ\to 3μ$. We investigate constraints from flavour observables and direct LHC searches for $pp \to Z' \to μ^+μ^-$. Our model successfully generates the measured fermion-mixing matrices and does not require vector-like fermions, unlike previous attempts to explain these anomalies.

description: Optimization of Josephson oscillators requires a quantitative understanding of their microwave properties. A Josephson junction has a geometry similar to a microstrip patch antenna. However, it is biased by a dc-current, distributed over the whole area of the junction. The oscillating electric field is generated internally via the ac-Josephson effect. In this work I present a distributed, active patch antenna model of a Josephson oscillator. It takes into account the internal Josephson electrodynamics and allows determination of the effective input resistance, which couples Josephson current to cavity modes in the transmission line formed by the junction. The model provides full characterization of Josephson oscillators and explains the origin of low radiative power efficiency. Finally, I discuss the design of an optimized Josephson patch oscillator, capable of reaching high efficiency and radiation power for emission into free space.

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: A chegada de refugiados exige da sociedade formas de acolhimento e integração, porém percebe-se que o Estado ainda não está preparado para acolhê-los, fazendo com que a sociedade civil tenha que suprir algumas demandas. Deve-se partir pela identificação das dificuldades enfrentadas pelos mesmos para assim conseguir intervir. Considerando tal contexto, a partir de um estudo de natureza qualitativa, esse artigo centra-se na análise de um diagnóstico participativo com refugiados, realizado pelo Instituto Migrações e Direitos Humanos, em Brasília, em 2014. Percebe-se que a maioria das necessidades dos refugiados e solicitantes de refúgio são justamente aquelas relacionadas aos processos de solicitação de refúgio, por serem muito morosos. Foi possível concluir que conhecer as demandas dos refugiados é essencial para propor encaminhamentos futuros voltados para as reais necessidades de tais sujeitos, nomeadamente aquelas voltadas para o acesso à saúde, educação, trabalho e, ainda, para algumas especificidades em função do gênero dos sujeitos.

description: The high-mass star-forming site G009.62+00.20E hosts the 6.7 GHz methanol maser source with the greatest flux density in the Galaxy which has been flaring periodically over the last ten years. We performed high-resolution astrometric measurements of the CH3OH, H2O, and OH maser emission and 7 mm continuum in the region. The radio continuum emission was resolved in two sources separated by 1300 AU. The CH3OH maser cloudlets are distributed along two north-south ridges of emission to the east and west of the strongest radio continuum component. This component likely pinpoints a massive young stellar object which heats up its dusty envelope, providing a constant IR pumping for the Class II CH3OH maser transitions. We suggest that the periodic maser activity may be accounted for by an independent, pulsating, IR radiation field provided by a bloated protostar in the vicinity of the brightest masers. We also report about the discovery of an elliptical distribution of CH3OH maser emission in the region of periodic variability.

Techniques for obtaining qualitative data in written online inquiries

Year: 2016

description: In this paper we discuss the possible benefits of written asynchronous online inquiries for qualitative social research and digital inquiry techniques. Although qualitative interviews and group discussions have been conducted online since the mid-1990s, we know very little about their methodological benefits, their concrete execution techniques of digital questioning, active listening and relationship building. We show the methodological potential of written research exchanges which enable the articulation (and thus the empirical reconstruction) of statements which are not yet socially ratified. Furthermore, we discuss the importance of face-to-face contact before the actual inquiry, which can increase the mutual commitment between researchers and respondents. Finally, we argue that signals of permanent ‘listening’ and recognition of the respondents’ expressions are constitutive in obtaining qualitative data, which means a personal and trustful communication style and a high frequency of contact with probably a non-directive questioning technique.

description: Heavy-quark spin symmetry (HQSS) implies that in the direct decay of a heavy quarkonium with spin $S$, only lower lying heavy quarkonia with the same spin $S$ can be produced. However, this selection rule, expected to work very well in the $b$-quark sector, can be overcome if multiquark intermediate states are involved in the decay chain, allowing for transitions to the final-state heavy quarkonia with a different spin $S^{\prime}$. In particular, the measured decays $Υ(10860)\to πZ_b^{(\prime)} \to ππΥ(nS)$ $(n=1,2,3)$ and $Υ(10860)\to πZ_b^{(\prime)} \to ππh_b(mP)$ ($m=1,2$) appear to have nearly equal strengths which is conventionally explained by a simultaneous presence of both $S_{b\bar{b}}=0$ and $S_{b\bar{b}}=1$ components in the wave functions of the $Z_b$'s in equal shares. Meanwhile, the destructive interference between the contributions of the $Z_b$ and $Z_b'$ to the decay amplitude for a $ππh_b$ final state kills the signal to zero in the strict HQSS limit. In this paper, we discuss how the HQSS violation needs to be balanced by the narrowness of the $Z_b^{(\prime)}$ states in the physical case, to allow for equal transition strengths into final states with different total heavy quark spins, and how spin symmetry is restored as a result of a subtle interplay of the scales involved, when the mass of a heavy quark becomes infinite. Moreover, we demonstrate how similar branching fractions of the decays into $ππh_b$ and $ππΥ$ can be obtained and how the mentioned HQSS breaking can be reconciled with the dispersive approach to the $ππ/ K\bar K$ interaction in the final state and matched with the low-energy chiral dynamics in both final states.

description: The oloid is the convex hull of two circles with equal radius in perpendicular planes so that the center of each circle lies on the other circle. It is part of a developable surface which we call extended oloid. We determine the tangential system of all inscribed quadrics $\mathcal{Q}_λ$ of the extended oloid $\mathcal{O}$ where $λ$ is the system parameter. From this result we conclude parameter equations of the touching curve $\mathcal{C}_λ$ between $\mathcal{O}$ and $\mathcal{Q}_λ$, the edge of regression $\mathcal{R}$ of $\mathcal{O}$, and the asymptotes of $\mathcal{R}$. Properties of the touching curves $\mathcal{C}_λ$ are investigated, including the case that $λ\rightarrow\pm\infty$. The self-polar tetrahedron of the tangential system $\mathcal{Q}_λ$ is obtained. The common generating lines of $\mathcal{O}$ and any ruled surface $\mathcal{Q}_λ$ are determined. Furthermore, we derive the curves which are the images of $\mathcal{C}_λ$ and $\mathcal{R}$ when $\mathcal{O}$ is developed onto the plane.

Mode pumping in photonic lattices using a single tailored auxiliary waveguide

description: In this work, we propose a completely general method to pump the gapped topological modes of a lattice of optical waveguides by controlling the propagation constant of an auxiliary waveguide and its coupling to the main lattice. In this way, we can transform a single-waveguide excitation on the auxiliary waveguide into a specific mode of the lattice. We also demonstrate the possibility of transferring supermodes between two waveguide lattices using the same method. We illustrate the results by pumping and transferring the topological modes of Su-Schrieffer-Heeger lattices. For both scenarios, we show that purities above 99\% can be achieved with parameter values within experimental reach. Additionally, we demonstrate how the technique can be used to pump the bulk modes of the lattice for low number of waveguides or enable mode conversion between waveguide lattices.

description: We present a new 2 Ms Chandra observation of the cluster merger Abell 2146, which hosts two huge M~2 shock fronts each ~500 kpc across. For the first time, we resolve and measure the width of cluster merger shocks. The best-fit width for the bow shock is 17+/-1 kpc and for the upstream shock is 10.7+/-0.3 kpc. A narrow collisionless shock will appear broader in projection if its smooth shape is warped by local gas motions. We show that both shock widths are consistent with collisionless shocks blurred by local gas motions of 290+/-30 km/s. The upstream shock forms later on in the merger than the bow shock and is therefore expected to be significantly narrower. From the electron temperature profile behind the bow shock, we measure the timescale for the electrons and ions to come back into thermal equilibrium. We rule out rapid thermal equilibration of the electrons with the shock-heated ions at the 6 sigma level. The observed temperature profile instead favours collisional equilibration. For these cluster merger shocks, which have low sonic Mach numbers and propagate through a high $β$ plasma, we find no evidence for electron heating over that produced by adiabatic compression. Our findings are expected to be valid for collisionless shocks with similar parameters in other environments and support the existing picture from the solar wind and supernova remnants. The upstream shock is consistent with this result but has a more complex structure, including a ~2 keV increase in temperature ~50 kpc ahead of the shock.

description: Quantum networks have been shown to connect users with full-mesh topologies without trusted nodes. We present advancements on our scalable polarisation entanglement-based quantum network testbed, which has the ability to perform protocols beyond simple quantum key distribution. Our approach utilises wavelength multiplexing, which is ideal for quantum networks across local metropolitan areas due to the ease of connecting additional users to the network without increasing the resource requirements per user. We show a 10 user fully connected quantum network with metropolitan scale deployed fibre links, demonstrating polarisation stability and the ability to generate secret keys over a period of 10.8 days with a network wide average-effective secret key rate of 3.38 bps.
