OBJECTIVE To investigate the relationship between several physiological variables that can be easily obtained during cycle ergometer gradual testing (for example, peak power output (W(peak)), Vo(2max), or ventilatory threshold (VT)) and actual (>50 km) time trials (TT) time performance during the Tour de France. METHODS We collected data in professional cyclists from the first TT of the 1998 ...

In this Letter, we show that the explosive percolation is a novel continuous phase transition. The order-parameter-distribution histogram at the percolation threshold is studied in Erd˝ os-Rényi networks, scale-free networks, and square lattice. In finite system, two well-defined Gaussian-like peaks coexist, and the valley between the two peaks is suppressed with the system size increasing. Thi...

In social movements, the decision of individuals to participate depends both on their own preferences as well as the behavior of others. Three examples of this type of interaction are the Arab Spring protests, Kickstarter campaigns, and internet memes. One way of modeling this is Granovetter’s threshold model of collective action, in which each agent needs to see a “threshold” level of particip...

Taste thresholds for sucrose, NaCl, QHCl and citric acid were examined over the lifetime of seven rats. Significant yet subtle decreases in taste sensitivity were observed in the oldest subjects only.

To evaluate the possible contribution of high-frequency hearing to frequency discrimination at lower frequencies, pure-tone frequency discrimination tasks at 1200 Hz, with and without high-frequency masking noise, were performed by two highly practiced normal-hearing listeners. Signal levels ranged from 10 to 80 dB SPL. Spectra of the three high-frequency masking noises ranged from 1.8 to 2.1 k...

Frequency discrimination was measured for a wide range of center frequencies (0.25-8 kHz) using three different tasks. In the first (difference limens for frequency, DLFs) subjects were required to indicate which of two successive tone pulses was higher in frequency. In the second (difference limens for change, DLCs), two successive pairs of tone pulses were presented; one pair had the same fre...

This paper presents a novel secret voting scheme which fully conforms to the requirements of large scale elections. The participants in the scheme are voters, candidates, an administrator, and a counter. The scheme uses threshold encryption to preserve the privacy and accuracy of the votes against dishonesty of voters, candidates, the administrator , and the counter. It also ensures veriiabilit...

This report covers work of the Optics Division at Lincoln Laboratory for the period 1 January through 30 June 1974. The topics covered are laser technology and propagation and optical measuremerts and inst r urn ent ati on. Additional information on the optics program may be found in the semiannual technical summary reports to the Advanced Research Projects Agency.

We consider the problem of updating beliefs for binary random variables, when probability assessments are elicited for them based on information of varying quality. We propose the threshold model, a Bayesian updating procedure where only measures of location and correlation have to be speciied before any updating is possible. The main aspect of this model is the use of Jeerey's conditionalizati...

Two mature elite Sambo wrestlers were studied during a 22-day pre-European Championship period, during which they were to lose weight and maintain their top physical performance characteristics. During this time the athletes underwent intensive training coupled with a hypocaloric diet. Both lost approximately 8% of their initial body weight, while maintaining their pre-weight loss maximum oxyge...
