'94 , but the numerical results has not been fully provided with varying decision threshold. In this paper, the performance of the PIC receiver using null zone hard decision is shown in a Rayleigh fading channel. Also, a new PIC receiver with an adaptive decision threshold is proposed. In the proposed new PIC receiver, the decision threshold for partial cancellation is adjusted according to the...

We designate lectotypes and propose nomenclatural changes in Xylographus Mellié (Coleoptera, Ciidae) based on type specimens deposited in the Museum of Comparative Zoology (USA), Museum für Naturkunde Berlin (Germany), the Natural History Museum (UK), Muséum d'Histoire Naturelle de la Ville de Genève (Switzerland), Muséum National d'Histoire Naturelle (France), Naturhistoriska Riksmuseet (Swede...

Direct Sequence Code Division Multiple Access (DS-CDMA) system is well known wireless technology. This system suffers from MAI (Multiple Access Interference) caused by Direct Sequence users. Multi-User Detection schemes were introduced to detect the users’ data in presence of MAI. In Multi stage Partial parallel interference cancellation (MP-PIC) method complexity is more than multi stage conve...

Cryo-electron microscopy has enabled unprecedented progress in the quest to reveal structure of whole transcription preinitiation complex. Four recent studies pave way for a complete description how is initiated at near-atomic level.

A parallel, three-dimensional electrostatic PIC code is developed for largescale electric propulsion simulations using parallel supercomputers. Two algorithms are implemented in the code, a standard finite-difference (FD) PIC and a newly developed immersed-finite-element (IFE) PIC. The IFE-PIC is designed to handle complex boundary conditions accurately while maintaining the computational speed...
