Perceptual multistability, alternative perceptions of an unchanging stimulus, gives important clues to neural dynamics. The present study examined 56 perceptual dominance time series for a Necker cube stimulus, for ambiguous motion, and for binocular rivalry. We made histograms of the perceptual dominance times, based on from 307 to 2478 responses per time(More)
We investigated the role of 24-epibrassinolide (EBR) in the amelioration of phenanthrene (PHE) stress in tomato (Solanum lycopersicum L.). Exposure to PHE (300 μM) significantly decreased shoot and root length (19 and 16 %, respectively), fresh mass (35 and 43 %, respectively), contents of chlorophyll a (26 %), chlorophyll b (27 %) and carotenoids (18 %) in(More)
Human U251 and D54 glioma cells were tested for expression of 25 glioma-associated tumor antigen precursor proteins (TAPP) under hypoxic (1% O(2)) or normoxic (21% O(2)) conditions. Hypoxic glioma cell lines increased their mRNA expression for nine TAPP (Aim2, Art-4, EphA2, EZH2, Fosl1, PTH-rP, Sox 11, Whsc2 and YKL-40), as assessed by quantitative reverse(More)
This paper analyzes the impact of narrow-band interference (NBI) on the performance of multi-band (MB) OFDM ultra wideband communication systems. A comprehensive study of the effects of NBI on the analog-to-digital converter (ADC) and carrier synchronization algorithm is presented. The overall impact of NBI is demonstrated by quantifying the MB-OFDM(More)
To avoid significant losses that might be induced by a narrowband interference (NBI) on the performance of a multi-band (MB) OFDM ultra wideband (UWB) receiver, efficient NBI mitigation schemes are required. This paper proposes a novel mixed-mode NBI suppression scheme that relies on the cooperation between a digital NBI detector and an adaptive analog(More)
Patrick Suppes is one of the most influential pioneers in the field of computers and education. In this article, the authors make a brief biography for him and introduce his outstanding achievements in terms of both research and practice in learning with technology, ending with concluding remarks.
