Effects of ISI and flash duration on the identification of briefly flashed stimuli

Spatial Vision, 2005
The identification accuracy of briefly flashed stimuli followed by an interstimulus interval (ISI) of variable length was compared to that obtained with longer flashes that prolonged the exposure of the stimulus throughout the ISI. The interval between the onset of the stimulus and the onset of the mask (stimulus onset asynchrony (SOA)) was the same in

Visual masking and the contrast-flash effect

Vision Research, 1981
Abstract We have compared the effect of disk-shaped masking flashes, 2° or 8° dia, to the effect of an annular contrast-flash, 2–8° dia, on the threshold for a 2° test flash. At all stimulus onset asynchronies and stimulus intensities studied, the threshold curves for the annulus are similar to those for the masking disks.

Object Updating and the Flash-Lag Effect

Psychological Science, 2004
Flash lag is a misperception of spatial relations between a moving object and a briefly flashed stationary one. This study began with the observation that the illusion occurs when the moving object continues following the flash, but is eliminated if the object's motion path ends with the flash.

Effect of fever on menopausal hot flashes

Maturitas, 1992
Some women report that they have fewer hot flashes when they have a fever. This is the first case of physiological monitoring of hot flashes during fever in a subject with a well documented pattern of frequent hot flashes when afebrile. During fever, there were fewer hot flashes than during afebrile periods, and these hot flashes also tended to be less

The effect of background luminance on the brightness of flashes

Vision Research, 1969
Interocular brightness matches were made between flashes of light, one to each eye. added to large steady uniform backgrounds of different luminances. The backgrounds were binocularly superimposed. Under these conditions, constant-brightness curves (Log ΔI vs. Log I) were of approximately the same shape as the increment threshold curve.

Gabapentin’s effects on hot flashes and hypothermia

Neurology, 2000
The author describes six cases in which gabapentin treatment reduced the frequency of hot flashes. In addition, gabapentin treatment enhanced the frequency of hypothermic episodes in a separate patient with known hypothalamic dysfunction. Gabapentin may act directly upon temperature regulatory centers.

Radiation effects on NAND Flash memories

2010
Electronic chips operating at sea level are constantly bombarded by a shower of high-energy neutrons, which originate from the interactions of cosmic rays with the outer layers of the atmosphere. The neutron flux changes with altitude, reaching a peak very close to the cruise altitude of airplanes, posing an even more serious threat to avionics.

FLASH radiotherapy: technical advances, evidence of the FLASH effect and mechanistic insights

Biomedical Physics & Engineering Express
Abstract Cancer is one of the leading causes of death worldwide, responsible for nearly 10 million deaths in 2020, with approximately 50% of patients receiving radiation therapy as part of their treatment (Baskar et al 2012). Preclinical investigations studies have shown that FLASH radiotherapy (FLASH-RT), delivering radiation in ultra ...

The Effect of Flash Frequency on the Apparent Intensity of Flashing Lights Having Constant Flash Duration

Transactions of the Illuminating Engineering Society, 1940
Observations were made in the laboratory, on the effect of varying the flash frequency on the apparent intensity of flashing lights having durations of 1/40th second and 1/10th second. The majority of the readings were taken at an illumination level of 0.5 mile-candle on the eye. This is the desirable lower limit of illumination on the eye for adequate
