    The velocity diagram for traveling waves by Al Haj, Mohammad, Monneau, Régis

    Published 2023-05-01
    “…In this Note, we consider traveling waves in a reaction-diffusion equation in dimension one. Motivated by the motion of dislocations in crystals, we introduce an additive parameter $\sigma $ in the reaction term, which may be interpreted as an exterior force applied on the crystal. …”

    Fairy circles and temporal periodic patterns in the delayed plant-sulfide feedback model by Xin Wei, Jianjun Paul Tian, Jiantao Zhao

    Published 2024-08-01
    “…Incorporating the self-regulatory mechanism with time delay to a plant-sulfide feedback system for intertidal salt marshes, we proposed and studied a functional reaction-diffusion model. We analyzed the stability of the positive steady state of the system, and derived the sufficient conditions for the occurrence of Hopf bifurcations. …”

    Voice Quality in British English. Its Nature, Functions and Applications by Stephan Wilhelm

    Published 2019-11-01
    “…We suggest that, like segmental elements or intonation features, the use of voice quality settings can spread through processes of social or geographical diffusion. Lastly, we point out that the study of voice quality may prove useful in a wide variety of domains such as forensic linguistics, voice recognition, speech synthesis and crucially EFL teaching.…”

    Le « modèle américain » de la consommation de masse by Emily S. Rosenberg

    Published 2009-04-01
    “…Ce modèle auquel adhère, non sans critiques, la société américaine de l’entre-deux guerres via l’essor de la publicité, devient un enjeu de l’affrontement idéologique entre les États-Unis et l’URSS durant la guerre froide. La diffusion de l’« American Way of Life », qui accompagne la reconstruction de l’Europe et sert de contrepoint au communisme, démontre sa remarquable flexibilité et lui permet de se traduire moins par une « américanisation » des modes de vie que par un déploiement d’un consumérisme multi-local s’adaptant à tous les contextes nationaux. …”

    A Case Report on Chikungunya Virus-Associated Encephalomyelitis by Harsh Khatri, Heli Shah, Dhara Roy, Kaushalendra Mani Tripathi

    Published 2018-01-01
    “…The neurological manifestations are uncommon and incorporate meningoencephalitis, myelitis, Guillain–Barre syndrome, cranial nerve palsies, myelopathy, and neuropathy; MRI abnormalities in patients with encephalopathy from India have been reported in the form of multiple punctuate white matter lesions that are more prominent on diffusion-weighted MRI than on T2 or T1. Here, we present an intriguing case of chikungunya encephalomyelitis who presented to our tertiary care hospital with quadriparesis and urinary retention. …”
