Ecological and environmental heterogeneity can produce genetic differentiation in highly mobile species. Accordingly, local adaptation may be expected across comparatively short distances in the presence of marked environmental gradients. Within the European continent, wolves (Canis lupus) exhibit distinct north-south population differentiation. We investigated more than 67-K single nucleotide ...
Natural human faces with abnormal visual features produce uncomfortable impressions, but artificial faces (e.g., robotic faces) do not necessarily do so. This is an example of the phenomenon called the uncanny valley. We hypothesized that this phenomenon indicates that natural and artificial faces are processed by different perceptual mechanisms, or they are processed differently by common mech...
Recent studies reveal that a deep neural network can learn transferable features which generalize well to novel tasks for domain adaptation. However, as deep features eventually transition from general to specific along the network, the feature transferability drops significantly in higher layers with increasing domain discrepancy. Hence, it is critical to formally reduce the dataset bias and e...
Adaptive divergence at the microgeographic scale has been generally disregarded because high gene flow is expected to disrupt local adaptation. Yet, growing number of studies reporting adaptive divergence at a small spatial scale highlight the importance of this process in evolutionary biology. To investigate the genetic basis of microgeographic local adaptation, we conducted a genome-wide scan...
BACKGROUND The adaptive maintenance of flower color variation is frequently attributed to pollinators partly because they preferentially visit certain flower phenotypes. We tested whether Gentiana lutea-which shows a flower color variation (from orange to yellow) in the Cantabrian Mountains range (north of Spain)-is locally adapted to the pollinator community. METHODS We transplanted orange-f...
nowadays,tourism industry considered as one of the main sources of income of a country.unfortunately and despite of owning plenty of cultural historical and natural attractions, iran has not reached to a proper position in this field. besides, the historical cities of a country are considered as the income resource and national wealth of it. qazvin with a rich cultural precedent, have suitable ...
This paper describes a process for extracting hybrid color features for natural scene images. There are different approaches to color feature analysis are tested on the classification of image from Oliva, Antonio Torralba database. For this purpose three set of image categories are taken viz coast, river, and mountains. The first method employs multispectral approach, in which image features ar...
background:poisoning with ethylene glycol (eg) can be fatal even if appropriate treatments are delivered. eg poisoning usually causes central nervous system depression, cardiovascular dysfunction, metabolic acidosis and acute renal failure (arf). case report:a 33-year-old man was referred to the emergency department with reduced consciousness and dyspnea of four-hour duration due to unknown rea...
