    Study on tunnel ventilation and pollutant diffusion mechanism during construction period. by Xiaoke Chang, Jianxi Ren, Rong Yang, Yan Tong

    Published 2025-01-01
    “…Ventilation technology is an important means to ensure effective control of pollutant concentration and safe production during tunnel drilling and blasting construction. This study combines theoretical derivation, numerical simulation, and mathematical statistics to explore the extraction of flow field distribution characteristics and pollutant transport and diffusion mechanisms in tunnels. …”

    Dynamically Adapted Mesh Construction for the Efficient Numerical Solution of a Singular Perturbed Reaction-diffusion-advection Equation by Dmitry V. Lukyanenko, Vladimir T. Volkov, Nikolay N. Nefedov

    Published 2017-06-01
    “…This  work develops  a theory  of the  asymptotic-numerical investigation of the  moving fronts  in reaction-diffusion-advection models.  By considering  the  numerical  solution  of the  singularly perturbed Burgers’s  equation  we discuss a method  of dynamically  adapted mesh  construction that is able to significantly  improve  the  numerical  solution  of this  type of equations.  …”

    Various Cultivars of Citrus Fruits: Effects of Construction on Gas Diffusion Resistance and Internal Gas Concentration of Oxygen and Carbon Dioxide by Kazuya Morimatsu, Keiji Konagaya

    Published 2024-11-01
    “…Various cultivars of citrus fruits have unique constructions, such as thick outer skin. These constructions generate gas diffusion resistance between the atmosphere and the fruit, which can limit the gas exchange of O<sub>2</sub> and CO<sub>2</sub>.This has not been sufficiently investigated. …”

    Probabilistic reduction and constructionalization: a usage-based diachronic account of the diffusion and conventionalization of the Spanish la de  <noun> que construction by Marttinen Larsson Matti

    Published 2024-11-01
    “…It is argued that the initial omission of cantidad can be accounted for by appealing to the notion of probabilistic reduction, whereby omission is feasible in contexts involving a high degree of constructional predictability. In the mapping out of change, conventionalization of the innovative la de <noun> que is most observable in contexts involving high constructional predictability and is least prominent in contexts of low constructional predictability. …”

    Diffusion Chaos in Reaction – Diffusion Boundary Problem in the Dumbbell Domain by S. D. Glyzin, P. L. Shokin

    Published 2013-06-01
    “…The conditions on chaotic oscillations emergence were studied and the dependence of invariant characteristics of the attractor on the bridge width was constructed. The diffusion parameter was chosen such that in the case of widest possible bridge (corresponding to a rectangular domain) the spatially homogeneous cycle of the problem is orbitally asymptotically stable. …”

    Comparison of lesion segmentation performance in diffusion-weighted imaging and apparent diffusion coefficient images of stroke by artificial neural networks. by Seok Jin Bang, Yong-Tae Kim, Young Jae Kim, Kwang Gi Kim

    Published 2025-01-01
    “…Stroke is the second leading cause of death, accounting for 11% of deaths worldwide. Comparing diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) images is important for stroke diagnosis, but most studies have focused on lesion segmentation using DWI. …”
