Background: Endodontic treatment aims in the preservation of extremely carious primary teeth. For root canal therapy to be successful, root canals must be properly prepared and effectively irrigated .Therefore, it is necessary to select the proper root canal disinfection method to preserve the primary tooth.

Using angle-resolved photoemission spectroscopy (ARPES) and density functional theory (DFT), an experimental and theoretical study of changes in the electronic structure (dispersion dependencies) and corresponding modification of the energy band gap at the Dirac point (DP) for topological insulator (TI) [Formula: see text] have been carried out with gradual replacement of magnetic Mn atoms by non-magnetic Ge atoms when concentration of the latter was varied from 10% to 75%. It was shown that when Ge concentration increases, the bulk band gap decreases and reaches zero plateau in the concentration range of 45-60% while trivial surface states (TrSS) are present and exhibit an energy splitting of 100 and 70 meV in different types of measurements. It was also shown that TSS disappear from the measured band dispersions at a Ge concentration of about 40%.

Article Synopsis
- Lithium-ion batteries are crucial for the electric vehicle (EV) industry due to their high energy density, low discharge rate, and long lifespan, making accurate State of Charge (SOC) estimation important for performance improvement.
- The proposed method combines the Thevenin 2RC battery model to capture the battery's non-linear dynamics with the Unscented Kalman Bucy Filter (UKBF) to enhance SOC estimation by dealing with measurement noise and nonlinearities.
- A simulation in Matlab Simulink reveals that the UKBF outperforms other estimation methods like EKF and UKF, achieving a notably lower Root Mean Square Error (RMSE) of 0.003276 for SOC estimation.
Overrated energy storage performances of dielectrics seriously affected by fringing effect and parasitic capacitance.

Dielectric capacitors are vital for modern power and electronic systems, and accurate assessment of their dielectric properties is paramount. However, in many prevailing reports, the fringing effect near electrodes and parasitic capacitance in the test circuit were often neglected, leading to overrated dielectric performances. Here, the serious impacts of the fringing effect and parasitic capacitance are investigated both experimentally and theoretically on different dielectrics including AlO, SrTiO, etc.
