Temporal Variation of Carboxyhemoglobin Concentrations

Archives of Environmental Health: An International Journal, 1969
Carboxyhemoglobin concentrations ([COHb]) were measured in 15 subjects by analysis of alveolar air samples collected at two-hour intervals during waking hours on seven consecutive days. Overall mean values were 3.80% COHb for five cigarette smokers and 1.64% COHb for ten nonsmokers. Analysis of the results indicates that long-term average [COHb] can be

Temporal Variations in Testicular Microcirculation

Journal of Andrology, 1999
ABSTRACT: Temporal variations in microcirculatory blood flow in the testis and blood pressure were examined in intact, pentobarbital‐anesthetized rats with a two‐channel laser Doppler flowmeter. The laser Doppler probes that measure local blood flow in a tissue volume of about 2 mm3 were placed either over the mid portion of the left and right testes ...

Variational Connectionist Temporal Classification

2020
Connectionist Temporal Classification (CTC) is a training criterion designed for sequence labelling problems where the alignment between the inputs and the target labels is unknown. One of the key steps is to add a blank symbol to the target vocabulary. However, CTC tends to output spiky distributions since it prefers to output blank symbol most of the

Hydroclimate temporal variations

2008
Temporal scale The history of the Earth's hydroclimate is very complex and efforts to understand hydroclimatic processes through time are hindered by the relatively short existence of humans on the planet. The ability to quantify climate variability is fundamental to understanding past and future hydroclimates and to developing a comprehensive ...
