    Efficacy of Different Irrigant Activation Systems on Debris and Smear Layer Removal: A Scanning Electron Microscopy Evaluation by Ronald Wigler, Moran Herteanu, Yuval Wilchfort, Anda Kfir

    Published 2023-01-01
    “…When the syringe and needle were used without activation, more debris and smear layer were found in the apical third of the canals. Activation of the final irrigant with each of the three devices significantly reduced the presence of debris in the apical third, compared to the syringe and needle final irrigation, with no difference among the three activation devices. …”

    Investigation of Theoretical Models, Pumping-Recharge Well Arrangements and System Performance of Abandoned Mine Water Source Heat Pump by Zhiqiang Zhang, Wenchao Zu, Wenke Zhang, Kexun Wang, Xueqing Ma, Ping Cui

    Published 2025-06-01
    “…The influences of different recharge temperatures, pumping and recharging flow rates, well spacings, hydraulic gradients, aquifer thicknesses, porosities and other factors on the pumping temperature are studied according to the selected pumping and recharging well arrangement scheme. Finally, by choosing a residential building as the analysis object, a simulation model of the abandoned mine water source heat pump heating system is constructed, which is compared with a gas boiler heating system, revealing the energy savings and environmental protection benefits of the abandoned mine water source heat pump system. …”

    Tribbles 3 Regulates the Fibrosis Cytokine TGF-β1 through ERK1/2-MAPK Signaling Pathway in Diabetic Nephropathy by Luwei Zhang, Jinhang Zhang, Xinnong Liu, Shengli Liu, Jun Tian

    Published 2014-01-01
    “…To reveal the expression and possible role of tribbles homolog 3 (TRB3) in the incidence of type 2 diabetic nephropathy, we used immunohistochemistry, real-time quantitative PCR, western blot analysis, and enzyme-linked immunosorbent assay (ELISA) to study the expression of TRB3, extracellular signal-regulated kinase 1/2 mitogen-activated protein kinase (ERK1/2 MAPK), transforming growth factor β1 (TGF-β1), and collagen type IV in kidneys of db/db diabetic mice and in murine renal mesangial cells stimulated with high glucose. …”

    H∞ Estimation for a Class of Lipschitz Nonlinear Discrete-Time Systems with Time Delay by Huihong Zhao, Chenghui Zhang, Guangchen Wang, Guojing Xing

    Published 2011-01-01
    “…Then, by introducing the Krein space model and applying innovation analysis approach, the minimum of the indefinite quadratic form is obtained in terms of innovation sequence. Finally, through guaranteeing the positivity of the minimum, a sufficient condition for the existence of the H∞ estimator is proposed and the estimator is derived in terms of Riccati-like difference equations. …”

    Observers of Fuzzy Descriptor Systems with Time-Delays by Hongbiao Fan, Min Meng, Jun-e Feng

    Published 2014-01-01
    “…Then, via linear matrix inequality (LMI) approach, both delay-dependent and delay-independent conditions for the existence of fuzzy state observers are obtained. Finally, two numerical examples are provided to illustrate the proposed method.…”
