Synchronization sensitivity of block-IFDMA systems
IEEE Transactions on Wireless Communications, 2010In this paper, we present a comprehensive study of the performance of a new model of DFT-precoded OFDMA with block-interleaved subcarrier allocation: B-IFDMA. The impact of the phase and timing jitter on the performance degradation for the two variants of B-IFDMA, namely joint-DFT and added-signal B-IFDMA is studied.

Sensitivity analysis for the block Cholesky downdating problem
International Journal of Computer Mathematics, 2019Some improved rigorous perturbation bounds with normwise perturbation for the block Cholesky downdating problem are first derived by combining the modified matrix-vector equation approach with the ...

Contingent alpha blocking: Conditioning or sensitization?
Electroencephalography and Clinical Neurophysiology, 1965Abstract 1. 1. To determine whether pairing of two signals was necessary to produce a “conditioned” alpha blocking response, the EEG responses in fourteen subjects were first habituated to tone. Following repeated, independent exposure to a flickered light stimulus, 57% of the subjects showed 79% alpha blocking responses to three test tones. This

Sensitivity and specificity of different conduction block criteria
Clinical Neurophysiology, 2000To resolve the discrepancy between conduction block criteria derived from healthy controls and stricter criteria suggested by computer simulation of interphase cancellation through altered motor units.An EMG database provided control nerves from patients with amyotrophic lateral sclerosis (ALS) or neural muscular atrophy (CMT1) (disease controls) and ...

Sensitization and association in alpha blocking “conditioning”
Electroencephalography and Clinical Neurophysiology, 1968Abstract 1. 1. The main purpose of this investigation was to determine whether the typical alpha blocking “conditioned” response is a response which requires pairing of stimuli in a precise relationship or a form of sensitization. This was accomplished by combining a delayed “conditioning” with a simple discrimination design, and measuring ...

Ion and Temperature Sensitive Polypeptide Block Copolymer
Biomacromolecules, 2014A poly(ethylene glycol)/poly(L-alanine) multiblock copolymer incorporating ethylene diamine tetraacetic acid ([PA-PEG-PA-EDTA(m)) was synthesized as an ion/temperature dual stimuli-sensitive polymer, where the effect of different metal ions (Cu(2+), Zn(2+), and Ca(2+)) on the thermogelation of the polymer aqueous solution was investigated.

Memantine blocks sensitization to the rewarding effects of morphine
Brain Research, 2009Knowledge regarding the specific brain changes and neural plasticity processes produced by repeated drug exposure may be used to advance the understanding of the neurobiology of addiction in order to design appropriate medications. In the present study, the influence of N-methyl-d-aspartate (NMDA) glutamatergic receptors on sensitization to the motor ...
