TO THE EDITOR: Cell membrane capacitance Cm is a fundamental property of excitable cells. It scales with the cell surface area and is therefore used for cell size estimation and most important for normalizing currents and conductances. Consequently, proper knowledge of Cm is also crucial for accurate cell modeling (7). Whole cell patch-clamp technique has led to the development of elaborate met...

This paper investigates the performance of a seven-level Packed U Cell (PUC7) inverter-based transformerless Dynamic Voltage Restorer (DVR) topology under short-time voltage variations (voltage sags and swells). Unlike existing multilevel inverter (MLI)-based DVR solutions, proposed structure requires only one DC source (suitable for PV-based systems), capacitor, six switching devices to genera...

The proton exchange membrane (PEMFC) fuel cell represents the energy of the future, in parallel with hydrogen. However, this technology must meet many technical challenges related to performance and durability before being sold on a large scale. It is well known that these challenges are closely linked to water management. This paper develops and implements a model of PEM fuel for simulation to...

tellurium (te) nanostructures have been successfully synthesized via a simple hydrothermal methodfrom the reaction of a tecl4 aqueous solution with thioglycolic acid (tga) as a reductant. tga can be easily oxidized to the corresponding disulfide [sch2co2h]2, which in turn can reduce tecl4 to te. the obtained te was characterized by xrd, sem, eds, and drs. the effect of reducing agent on morphol...

Properties of the whole-cell K+ currents and voltage-dependent activation and inactivation properties of single K+ channels in clonal pheochromocytoma (PC-12) cells were studied using the patch-clamp recording technique. Depolarizing pulses elicited slowly inactivating whole-cell K+ currents, which were blocked by external application of tetraethylammonium+, 4-aminopyridine, and quinidine. The ...

This paper proposes a bias detection method in the voltage measurement of lithium-ion (Li-ion) battery cells to identify faulty sensor(s). The proposed is based on Bayesian probabilistic approach that detects possible any cell real-time. A hypothesis bank constructed for magnitudes each cell. Subsequently, fault algorithm computes probability associated with all hypotheses. Once certain converg...

Abstract: Due to the low cost, small size, and ease of control, the switched-capacitor (SC) battery equalizers are promising among active balancing methods. However, it is difficult to achieve the full cell equalization for the SC equalizers due to the inevitable voltage drops across Metal-Oxide-Semiconductor Field Effect Transistor (MOSFET) switches. Moreover, when the voltage gap among cells ...
