As an important component of Negative ion based Neutral Beam Injector (NNBI), the cryopump mainly provides a suitable vacuum environment for beam generation and transmission.In the paper, Liquid nitrogen (LN2) pipe structure models of two cryopumps were established for simulation and experimental studies.Thermal analysis of the thermal radiation sh
Direction of arrival (DOA) estimation is an important topic in array signal processing.Currently, most research activities are focused on the single signal transmission (SST) type of signals, i.e.only one physical signal is used to carry the information from a transmitter to a receiver with a given polarisation setting.However, to make full use of
We have previously shown that spontaneous release of glutamate in the entorhinal cortex (EC) is tonically facilitated via activation of presynaptic NMDA sassy spheres candy receptors (NMDAr) containing the NR2B subunit.Here we show that the same receptors mediate short-term plasticity manifested by frequency-dependent facilitation of evoked glutama
Adobe bricks, formed from raw clay, are used hybrid racing shifter rsx as construction materials since ancient times.Their main drawback is a low flexural and compressive strength.Agave bagasse is a waste material from the Mezcal production process.Angustifolia haw agave bagasse fiber was added to improve the properties of adobes.Adobe modbiv brick
