The radio properties of 4C21.53 have been an enigma for many years. First, the object displays interplanetary scintillations (IPS) at 81 MHz, indicating structure smaller than 1 are s, despite its low galactic latitude (−0.3°)1. IPS modulation is rare at low latitudes because of interstellar angular broadening. Second, the source has an extremely steep

This paper opens with a discussion of various methods of measuring short time intervals and then proceeds to describe a condenser chronoscope suitable for the measurement of intervals initiated and terminated by momentary or sustained makes or breaks in electrical circuits. The range is from 2 millisec to 1 000 millisec. The voltage on the condenser is

Stippling is a popular and fascinating sketching art in stylized illustrations. Various digital stippling techniques have been proposed to reduce tedious manual work. In this paper, we present a novel method to create high-quality color stippling from an input image in milliseconds.

Measuring sub-millisecond delays in spiking activity with millisecond time-bins
Neuroscience Letters, 2009Recent evidence indicates that sub-millisecond delays in neuronal spiking activity may be relevant for neural coding. Estimates of these delays are usually made from cross-correlation histograms (CCH) binned to 1ms. We investigated the degree to which it is possible to measure delays with sub-millisecond precision when one computes CCHs with bin sizes >

Review of Scientific Instruments, 1951
A device giving a time delay up to 10-sec duration and having a precision of 1 millisec is described. A simplified form of the device can be employed as a trigger-operated stop clock for timing periods of any length.

CHI '01 extended abstracts on Human factors in computer systems - CHI '01, 2001
For years, software engineers have been told that applications must respond to user events within 100 milliseconds to seem instantaneous, yet this assumption has never been systematically tested. In this research, we attempt to establish thresholds of detection for changes in a graphical user interface using adaptive tracking. For keyboard interactions,

Calibrating Prejudice in Milliseconds
Social Psychology Quarterly, 2008Psychological social psychologists have devoted great effort to measuring the elusive construct of unconscious prejudice. However, recent work underscores both the psychometric flaws of these measures and the weaknesses in claims that they predict behavior in realistic organizational settings.

A study of the flux density and component emission of four millisecond radio pulsars shows that on average millisecond radio pulsars have steeper spectra than slow period pulsars. The results of flux density measurements of four millisecond pulsars, PSRs 1620-26, 1821-24, 1855+09, and 1937+21, have been made to determine their spectral indices in the ...
