Balancing natural killer cell activation through paired receptors
Nature Reviews Immunology, 2015Natural killer (NK) cells are innate lymphocytes that are crucial for the control of infections and malignancies. NK cells express a variety of inhibitory and activating receptors that facilitate fine discrimination between damaged and healthy cells. Among them, a family of molecules that bind nectin and nectin-like proteins has recently emerged and ...

GROWTH ACTIVATION OF RESTING CELLS: INDUCTION OF BALANCED AND IMBALANCED GROWTH*
Annals of the New York Academy of Sciences, 1982Little is known about how mitogenic factors generate growth regulatory signals and how these are mediated within the cell. We have developed three different types of mitogenic stimuli in order to identify the possible existence of common denominators in a complex and perhaps pleiotypic signal-response system.

Wear Leveling-Aware Active Battery Cell Balancing
2024 37th International Conference on VLSI Design and 2024 23rd International Conference on Embedded Systems (VLSID)Due to manufacturing variabilities and temperature gradients within an electric vehicle's battery pack, the capacities of cells in it decrease differently over time. This reduces the usable capacity of the battery - the charge levels of one or more cells might be at the minimum threshold while most of the other cells have residual charge.

Efficient decentralized active balancing strategy for smart battery cells
Design, Automation & Test in Europe Conference & Exhibition (DATE), 2017, 2017Among series-connected cells in large battery packs, such as those found in electric vehicles, a charge imbalance develops over time due to manufacturing and temperature variations. Therefore, active balancing strategies can be employed in Battery Management Systems (BMSs) to attain a charge balance among cells by transferring charge between them ...

T cells activation and cytokines balance in active and cured tuberculosis (40.7)
The Journal of Immunology, 2010Abstract Tuberculosis is still a major health problem around the world and the understand of immune response against Mycobacterim tuberculosis is necessary for the development of new strategies for control disease progression. Activation of CD4+ and CD8+ T-cells by flow cytometry and the levels of cytokines in culture supernatants of ...

Sensor minimal cell monitoring with integrated direct active cell balancing
2017 Twelfth International Conference on Ecological Vehicles and Renewable Energies (EVER), 2017The presented paper introduces a sensor minimal battery observer, which allows the equipping of each stack with only one voltage and one current sensor, without losing the required individual cell measurement. The individual cell measurement is required not only for many Li-Ion applications with cell chemistry that can result in exothermic reactions ...

Battery Cell Balancer with Active Power Decoupling Function
2019 10th International Conference on Power Electronics and ECCE Asia (ICPE 2019 - ECCE Asia), 2019Nickel metal hybrid (NiMH) batteries are the most widely used batteries in hybrid electric vehicles (HEVs). Due to an imbalance among the individual cells caused by long-term use in HEV, a large number of NiMH batteries end up as toxic waste. Although the retired batteries cannot be employed as energy storage devices (ESDs) in electric vehicles (EVs ...

The Research of the Active Cells Balancing by the Inductive Charge Transfer
Applied Mechanics and Materials, 2010With the development of the electric vehicles, serial connected cells have a broad prospect in the future. But the difference of the serial connected cells especially for Li-ion cells is prone to cause a lot of problems, such as overcharge and overdischarge. For these reasons, various cells balancing methods are applied.
