We examined how hippocamal CA1 neurons process complex time-varying inputs that dendrites are likely to receive in vivo. We propose a functional model of the dendrite-to-soma input/output relationship that combines temporal integration and static-gain control mechanisms. Using simultaneous dual whole-cell recordings, we injected fifty seconds of subthreshold and suprathreshold zero-mean white-n...

Population genetic theory predicts that in small populations, random genetic drift will fix and accumulate slightly deleterious mutations, resulting in reduced reproductive output. This genetic load due to random drift (i.e., drift load) can increase the extinction risk of small populations. We studied the relationship between genetic variability (indicator of past population size) and reproduc...

This study aimed to clarify the relationship between media, learners’ perception of social presence, and output in communicative learning using synchronous computer-mediated communication (SCMC). In this study, we developed four types of SCMC: videoconferencing (image and voice), audioconferencing (voice but no image), text chat with image (image but no voice), and plain text chat (no image and...

This paper undertakes a cross-country study on the price-output gap relationship for selected industrial countries (Japan, the U.S., Germany, the U.K. and Canada). The estimation results show that the price-output gap relationship in these countries can be classified into two categories: (1) a Phillips Curve-type (in which the output gap fluctuation affects the inflation rate); and (2) a NAIRU ...

The literature on the relationship between real output growth and the growth rate in the price of oil, including an allowance for asymmetry in the impact of oil prices on output, continues to evolve. Here we show that a new technique, which allows us to control for both this asymmetry and also for the persistence of oil price changes, yields results implying that such control is necessary for a...

Alessandro Mecocci University of Siena Department of Information Engineering Via Roma, 56 53100-Siena Si , Italy Abstract. The problem of input noise affecting the subpixel classification is examined in order to assess its relationship with the output noise. The approach followed in this study was to investigate the output noise level obtained with a least-squares subpixel classification algori...

We analyse the output-unemployment relationship using an approach based on cross-recurrence plots and quantitative recurrence analysis. We use post-war period quarterly U.S. data. The results obtained show the emergence of a complex and interesting relationship.

PURPOSE Based on the resistance-rpm relationship for cycling, which is not unlike the force-velocity relationship of muscle, it is hypothesized that the cadence which requires the minimal muscle activation will be progressively higher as power output increases. METHODS To test this hypothesis, subjects were instrumented with surface electrodes placed over seven muscles that were considered to...

The relationship between research productivity and economic growth is the subject of information science which deals in this study to examine the impact of number of publications, research & development (R&D) expenditures and researchers involved in R&D activities on economic growth in the World’s largest regions for the period of 1980–2011. The study further expanded the research-growth nexus ...
