Isotopic fractionation occurs in the metabolic processes that transform dietary amino acids, and those already found in the body, into new proteinaceous tissues, such as keratin (Macko et al., 1987). Diet-fur discrimination factors of +2 to +2.6‰ for δ13C and +3.4‰ for δ15N were ...
Birds are among the best-studied animal groups, but their prehistoric diversity is poorly known due to low fossilization potential. Hence, while many human-driven bird extinctions (i.e., extinctions caused directly by human activities such as hunting, as well as indirectly through human-associated ...
From rabies to monkeypox, animal-to-human disease transmission are common. But why? Scientists are now partially linking it to climate change and deforestation.
The New Hunter-Gatherers: On the Productivization of Human Interaction in the Network Society 来自 Semantic Scholar 喜欢 0 阅读量: 26 作者: O Schwarz 摘要: The article discusses a set of emerging techno-social practices that transform interpersonal interactions into acts of production of ...
Previously, the temporal coding of periodic fluctuations has been shown to gradually transform into rate coding as the signals travel from the midbrain to the auditory cortex (Gao and Wehr 2015; Langner 1992; Wang et al., 2008). However, electrophysiological studies in humans and macaque monkeys...
data types68. In our case, it enabled a visual interpretation of the relative number of incidences of effect traits linked to different types of well-being in two-dimensional space. We did not transform the data before analysis (recommended for non-ecological data)69, but calculated a matrix...
The sperm cell can be any animal sperm cell, preferably non-human animal. In one preferred embodiment of this invention, the one or more polynucleotide molecules encode for a gene product that confers desired characteristics in the cells or the animals. In another preferred embodiment of this ...
By applying a recently validated transform to the interspike interval histogram, the mean voltage versus time trajectory of the motoneurone AHP was determined. Spike-triggered averaging was used to extract the muscle unit twitch from the whole muscle force with strict control over force variability ...
The mean and standard deviation of this baseline distribution was used to transform each correlation between the template and the resting-state patterns into a Z- score (Zi = (ri - μi)/σ). Correlations with a Z-score exceeding a value of 2 (Z > 2 ≈ p < 0.05) were...
All experiments were approved by the University of Groningen Committee for Animal Experimentation. Primary microglia culture Microglia cultures were prepared as previously described20. Briefly, brains were removed from 0- to 3-day-old C57Bl/6 pups, minced, dissociated for 25 min in 0.25% Trypsin...
