The multiple-look notion holds that the difference limen (DL) decreases with multiple observations. We investigated this notion for temporal discrimination in isochronous sound sequences. In Experiment 1, we established a multiple-look effect when sequences comprised nine standard time intervals (S) followed by an increasing number of comparison time intervals (C), but no multiple-look effect w...

Period Jitter Period jitter (JPER) is the time difference between a measured cycle period and the ideal cycle period. Due to its random nature, this jitter can be measured peak-to-peak or by Root of Mean Square (RMS). We begin by defining the clock rising-edge crossing point at the threshold VTH as TPER(n), where n is the time domain index, as shown in Figure 1. Mathematically, we can describe ...

It is frequently assumed that the accuracy with which luminance gratings can be detected depends solely on the signal-to-noise ratio at the output of a single linear channel. Proportionality between threshold elevation and power spectral density is implicit in this assumption. I demonstrate that this proportionality does not hold for 1-cycle/degree gratings masked by low-pass noise with a 0.5-c...

Synchronized human lymphoma cells treated with bleomycin exhibited the greatest sensitivity in G2. Doseresponse curves presented biphasic characteristics indicating the presence of sensitive and less sensitive cells in all stages of the cell cycle. Synchronized cells incubated with 1,3bis(2-chloroethyl)-l-nitrosourea also showed the greatest sensitivity in G2A threshold-type dose-response survi...

We show for an arbitrary lp norm that the property that a random geometric graph G(n, r) contains a Hamiltonian cycle exhibits a sharp threshold at r = r(n) = √ log n αpn , where αp is the area of the unit disk in the lp norm. The proof is constructive and yields a linear time algorithm for finding a Hamiltonian cycle of G(n, r) a.a.s., provided r = r(n) ≥

in this paper, a new combined power and refrigeration cycle is proposed, which combines the rankin power cycle and the ejector refrigeration cycle. this combined cycle produces both power output and refrigeration output simultaneously. this cycle is driven by the flue gas of gas turbines, industrial waste heats, solar energy and geothermal energy. an exergy analysis is performed to guide the th...

The famous Pósa conjecture states that every graph of minimum degree at least 2n/3 contains the square of a Hamilton cycle. This has been proved for large n by Komlós, Sarközy and Szemerédi. Here we prove that if p ≥ n−1/2+ε, then asymptotically almost surely, the binomial random graph Gn,p contains the square of a Hamilton cycle. This provides an ‘approximate threshold’ for the property in the...

Experiments 1 and 2 compared, with a single-stimulus procedure, the discrimination of filled and empty intervals in both auditory and visual modalities. In Experiment 1, in which intervals were about 250 msec, the discrimination was superior with empty intervals in both modalities. In Experiment 2, with intervals lasting about 50 msec, empty intervals showed superior performance with visual sig...
