Beyond Language

The authors of this paper invite you to imagine you are holding a kaleidoscope. As you put it against the light, an orderly pattern of pieces of glass creates a design pleasing to the eye; but when you give it a shake, the design changes completely. The colours are still the same but the design has reconfigured itself into a different pattern. In the same way, at strategic points in time, history shakes up the world and our perceptions of it. The evolution of globalisation and the rapid growth of computer technology have created precisely one of those strategic points and the world of education is no less shaken-up than any other aspect of our lives(Thurlow, Lengel and Tomic, 2004). Perhaps there is a need to remind ourselves, every now and then, that the world our students inhabit is very different to the one lived in by previous generations

Influence of Quantum Hall Effect on Linear and Nonlinear Conductivity in the FISDW States of the Organic Conductor (TMTSF)_2PF_6

We report a detailed characterization of quantum Hall effect (QHE) influence on the linear and non-linear resistivity tensor in FISDW phases of the organic conductor (TMTSF)2PF6. We show that the behavior at low electric fields, observed for nominally pure single crystals with different values of the resistivity ratio, is fully consistent with a theoretical model, which takes QHE nature of FISDW and residual quasi-particle density associated with different crystal imperfection levels into account. The non-linearity in longitudinal and diagonal resistivity tensor components observed at large electric fields reconciles preceding contradictory results. Our theoretical model offers a qualitatively good explanation of the observed features if a sliding of the density wave with the concomitant destruction of QHE, switched on above a finite electric field, is taken into account.Comment: 8 pages, 6 figures, submitted to EPJ

Safety profile od allergen specific imunotherapy of allergic rhinitis

Background: The aim of the presentation is to determine the safety profile of allergen specific immunotherapy, the frequency of local and/or systemic reactions, including subcutaneous (SCIT) and sublingual (SLIT) administrations. Methods: Our research was carried out in the diagnostic polyclinic section of the Allergology and Immunology Clinic of the Clinical Center of Serbia in Belgrade. We looked at retrospective insights into medical documentation, and all statistics was processed in the SPSS software. Results: Allergen specific immunotherapy (ASIT) is an effective treatment in IgE mediated allergic diseases: a) allergic rhinitis, with or without conjunctivitis, b) allergic asthma and c) hypersensitivity to venomas, with a range of patients from very good tolerance of AIT (no local, no systemic reactions 67.5 % ) to patients with very poor tolerance of AIT (there was not one case with anaphylactic shock, 0 % ). Conclusion: Its advantage as immunomodulatory treatment versus conventional pharmacological is that it alleviates the clinical picture, prevents the development of new symptoms, sensitizations and progression of rhinitis in asthma or a more severe disease. The quality of life is remarkably improved and also exhibits long term effects after the discontinuation of therapy

Coexistence of Superconductivity and Spin Density Wave orderings in the organic superconductor (TMTSF)_2PF_6

The phase diagram of the organic superconductor (TMTSF)_2PF_6 has been revisited using transport measurements with an improved control of the applied pressure. We have found a 0.8 kbar wide pressure domain below the critical point (9.43 kbar, 1.2 K) for the stabilisation of the superconducting ground state featuring a coexistence regime between spin density wave (SDW) and superconductivity (SC). The inhomogeneous character of the said pressure domain is supported by the analysis of the resistivity between T_SDW and T_SC and the superconducting critical current. The onset temperature T_SC is practically constant (1.20+-0.01 K) in this region where only the SC/SDW domain proportion below T_SC is increasing under pressure. An homogeneous superconducting state is recovered above the critical pressure with T_SC falling at increasing pressure. We propose a model comparing the free energy of a phase exhibiting a segregation between SDW and SC domains and the free energy of homogeneous phases which explains fairly well our experimental findings.Comment: 13 pages, 10 figures, revised v: fig.9 added, section 4.2 rewritten, accepted v: sections 4&5 improve

Resonant inelastic x-ray scattering probes the electron-phonon coupling in the spin-liquid kappa-(BEDT-TTF)2Cu2(CN)3

Resonant inelastic x-ray scattering at the N K edge reveals clearly resolved harmonics of the anion plane vibrations in the kappa-(BEDT-TTF)2Cu2(CN)3 spin-liquid insulator. Tuning the incoming light energy at the K edge of two distinct N sites permits to excite different sets of phonon modes. Cyanide CN stretching mode is selected at the edge of the ordered N sites which are more strongly connected to the BEDT-TTF molecules, while positionally disordered N sites show multi-mode excitation. Combining measurements with calculations on an anion plane cluster permits to estimate the sitedependent electron-phonon coupling of the modes related to nitrogen excitation

Anisotropic charge dynamics in the quantum spin-liquid candidate κ\kappa-(BEDT-TTF)2_2Cu2_2(CN)3_3

We have in detail characterized the anisotropic charge response of the dimer Mott insulator $\kappa$-(BEDT-TTF)$_2$\-Cu$_2$(CN)$_3$ by dc conductivity, Hall effect and dielectric spectroscopy. At room temperature the Hall coefficient is positive and close to the value expected from stoichiometry; the temperature behavior follows the dc resistivity $\rho(T)$. Within the planes the dc conductivity is well described by variable-range hopping in two dimensions; this model, however, fails for the out-of-plane direction. An unusually broad in-plane dielectric relaxation is detected below about 60 K; it slows down much faster than the dc conductivity following an Arrhenius law. At around 17 K we can identify a pronounced dielectric anomaly concomitantly with anomalous features in the mean relaxation time and spectral broadening. The out-of-plane relaxation, on the other hand, shows a much weaker dielectric anomaly; it closely follows the temperature behavior of the respective dc resistivity. At lower temperatures, the dielectric constant becomes smaller both within and perpendicular to the planes; also the relaxation levels off. The observed behavior bears features of relaxor-like ferroelectricity. Because heterogeneities impede its long-range development, only a weak tunneling-like dynamics persists at low temperatures. We suggest that the random potential and domain structure gradually emerge due to the coupling to the anion network.Comment: 14 pages, 13 figure

Managing institutional open access publishing deals: experiences of KAUST, Saudi Arabia

KAUST is a research-intensive graduate STEM institution with extensive research publishing output. Our commitment to open access is well-established through the first open access policy in the Middle East and continues with efforts to align with global Open Access initiatives, in addition to our research repository services, 17 Read and Publish contracts for hybrid journals were signed in 2019 and 2020 and aiming to increase doubling this number. We will explain the whole journey from making decisions to negotiate the deal, through promoting and managing the deal, and to assessing annual progress
