In many vertebrate species visible melanin-based pigmentation patterns correlate with high stress- and disease-resistance, but proximate mechanisms for this trait association remain enigmatic. Here we show that a missense mutation in a classical pigmentation gene, melanocyte stimulating hormone receptor ...
The ocean sunfish (Mola mola) is the world’s heaviest bony fish reaching a body mass of up to 2.3 tonnes. However, the prey M. mola consumes to fuel this prodigious growth remains poorly known. Sunfish were thought to be obligate gelatinous plankton feeders, but recent studies suggest a more generalist ...
Background Recently, the pharmaceutical manufacturing industry has been growing rapidly in many countries in the world, including in Arab countries. Pharmaceuticals reach aquatic environments and are prevalent at small concentrations in wastewater from the drug manufacturing industry and hospitals. ...
Life cycle assessment (LCA) is a powerful methodology for the study of health impacts and public policies. We performed this study to quantitatively explain the potential health impacts on disability-adjusted life years (DALYs) of corn produced in Mexico and imported from the United States of America ...
Technology for marine vessel monitoring and analysis combining Synthetic Aperture Radar (SAR) and Automatic Identification System (AIS) is presented in this paper. Detection results in SAR image are validated and analyzed with corresponding AIS information. In order to evaluate the performance of the ...
Monitoring the formation, development, melting, concentration, thickness, movement and other parameters of ice in the Okhotsk and Japan Seas is vital importance to physical oceanographers to study regional climate changes, air/sea/ice interaction, and formation of ocean water properties. Information ...
This study researched the estimation methods of nitrogen concentration of water hyacinth by hyperspectral remote sensing data. The spectral reflectance characteristics were analyzed based on field experiments consisting of different nitrogen levels in three growing seasons. This study investigated the ...
Based on Logistic model, the corresponding management model of fishery with two impulsive effects is proposed. Using the principles of optimization impulsive control and optimal theory, the controllers are designed to get the harvest moments and the corresponding levels. It not only can make the fishermen ...
Today's rapidly increasing environment satellite observations brought unprecedented opportunities for monitoring the earth environments with remote sensing measurement. The Joint Polar Satellite System (JPSS) is the National Oceanic and Atmospheric Administration's (NOAA) next generation polar satellite ...
Every day, ships of different type, size and origin cross the world seas. Not only for commerce and transport, but also for illegal activities. In addition to conventional positioning and tracking systems, detection with Earth observation satellites is an effective means to monitor human movements across ...
The discovery of anomalies and, more in general, of events of interest at sea is one of the main challenges of Maritime Situational Awareness. This paper introduces an event-based methodology for knowledge discovery without querying directly a large volume of raw data. The proposed architecture analyses ...
Abstract Understanding how speciation can occur without geographic isolation remains a central objective in evolutionary biology. Generally, some form of disruptive selection and assortative mating are necessary for sympatric speciation to occur. Disruptive selection can arise from intraspecific competition ...
In this article, three topics are being studied in order to understand the present state of cancer in Japan. First, the statistics on cancer mortality indicates that the mortality from cancer in young individuals has been decreasing during the last 50 years, although the total mortality from cancer ...
Circulating levels of chylomicron remnants (CMRs) increase postprandially and their composition directly reflects dietary lipid intake. These TG-rich lipoproteins likely contribute to the development of endothelial dysfunction, albeit via unknown mechanisms. Here, we investigated how the FA composition ...
Efficient scheduling strategy is crucial to a manufacturing system in flexible job shop environments. The flexible job shop scheduling problem (FJSP) is a complex combinatorial optimization problem due to the consideration of both machine assignment and operation sequence. In this paper, an efficient ...
Water is one of the main resources of nature, being the element directly related with maintenance of life in any ecosystem. For mankind, beside the biologic needs, water is used in many sectors of society, and one of them is electricity generation. For the full operation of hydroelectric power plants ...
When the aborigine community be hit by the natural disaster, the residents only can choose to leave their house or stay to restart. Tongmen village, in Hualien County, chose to initiate the River Restoration project. However, it is hard to resist the foreign merchants to get involved in free market ...
By using the data of city function of Shandong Peninsula Urban Agglomeration (SDPUA) in 2004, 2009 and 2014, Location quotient, K-means clustering algorithm and ARCGIS10.0 were applied to analyze the functional structure evolution of SDPUA. The results show that the cities functions and their evolution ...
Abstract Snails of the genus Stramonita are commonly found in the rocky intertidal habitat of the western Atlantic Ocean coast. They belong to a monophyletic taxon that occurs along the tropical and warm-temperate Atlantic and eastern Pacific rocky shores. This genus comprises different valid species ...
Estimating and detecting red tide is particularly challenging when using remotely sensed observations. Aqua-Terra MODIS provides a high resolution spatio-temporal coverage to detect red tide blooms. Both in-situ and satellite data were analyzed for red tide period and non-red tide period in this study. ...
