Human sleep-wake cycles are entrained by both natural and artificial light-dark cycles. However, little is known regarding when and how the photoperiod changes entrain the biological clock after conception. To investigate the dependence of sleep patterns in young infants on the natural and artificial light-dark cycles, 1,302 pairs of one-month-old infants and their mothers were asked to answer ...

the aim of this research is investigating the relations between climatic large scale signals and spring rainfall of khorasan-e razavi province. in this research, we have analyzed 38 years of rainfall data in khorasan-e razavi province, located in northeastern iran. we attempted to train artificial neural network based upon climatic large scale signals with 38 years of rainfall data. for perform...

The artificial gene D6D encoding the enzyme ∆⁶desaturase was designed and synthesized using the sequence of the same gene from the fungus Thamnidium elegans. The original start codon was replaced by the signal sequence derived from the wheat gene for high-molecular-weight glutenin subunit and the codon usage was completely changed for optimal expression in wheat. Synthesized artificial D6D gene...

The interaction and hierarchy of celestial and magnetic compass cues used by migratory songbirds for orientation has long been the topic of an intense debate. We have previously shown that migratory Savannah sparrows, Passerculus sandwichensis, use polarized light cues near the horizon at sunrise and sunset to recalibrate their magnetic compass. Birds exposed to a +/-90 deg. shifted artificial ...

Proper use of daylighting cannot only improve the visual comfort in indoor environment, but also reduce building energy consumption effectively. Studies on this topic have been mostly conducted for office buildings, but were limited for industrial buildings, where lighting is a major electricity consumer. This paper presents a study of daylighting performance in a large space industrial buildin...

Abstract Due to the multi-scale nature and complexity of flow field, it has always been difficult for hydrogeologists accurately grasp water cycle characteristics karst system. The inverse statistical model IsoSource were employed calculate spring age mixing ratio recharge sources four large groups in Jinan. hierarchical groundwater system was identified based on multiple factors. We found that...

Passive acoustic monitoring (PAM) in a variety of marine habitats has revealed distinct spatial and temporal variation fish sounds that are predicted to vary association with species composition abundance, as well diel seasonal influences. Reefs the Alabama Artificial Reef Zone (AARZ) northern Gulf Mexico (nGOM) have an associated fauna composed warm-temperate tropical reef species. AARZ reefs ...
