Purpose: A new method for magnetic resonance (MR) imaging water-fat separation using a convolutional neural network (ConvNet) and deep learning (DL) is presented. Feasibility of the method with complex and magnitude images is demonstrated with a series of patient studies and accuracy of predicted quantitative values is analyzed. Methods: Water-fat separation of 1200 gradient-echo acquisitions f...

In volleyball, blocking is highly correlated with team success. The identification of specific techniques that produce a more successful block would be helpful knowledge for coaches and players. This study compared the traditional, swing, and "chicken wing" blocking techniques in combination with the running step footwork pattern in order to determine which technique enabled athletes to perform...

Precise measurements were conducted in continuous flow seawater mesocosms located in full sunlight that compared metabolic response of coral, coral-macroalgae and macroalgae systems over a diurnal cycle. Irradiance controlled net photosynthesis (P net), which in turn drove net calcification (G net), and altered pH. P net exerted the dominant control on [CO3 (2-)] and aragonite saturation state ...

This paper examines the possible impact of climate change on Malaysian rice production. Using the Ricardian Method and farm household data, we have examined the effects on rice producers focusing on sharecropper adaptations and ecological causes. The principle goal of this research paper is to investigate the impact of climate variables such as temperature, rainfall and precipitation on rice pr...

Net annual soil carbon change, fossil fuel emissions from cropland production, and cropland net primary production were estimated and spatially distributed using land cover defined by NASA's moderate resolution imaging spectroradiometer (MODIS) and by the USDA National Agricultural Statistics Service (NASS) cropland data layer (CDL). Spatially resolved estimates of net ecosystem exchange (NEE) ...

Dynamics of resonant energy transfer of a single excitation in a molecular dimer system are studied in the simultaneous presence of diagonal and off-diagonal exciton-phonon coupling. It is found that, at given temperatures, the off-diagonal coupling can enhance both the coherence of the resonant energy transfer and the net quantity of energy transferred from an initially excited monomer to the ...

In corporate networks, idle desktop machines hardly ever sleep, mainly for the reason that turning off the hosts will affect the internet connection. There are number of systems have been proposed, few of them have mutually considered energy consumption and performance. In this article, we consider the case of file downloading, which is one of the most common internet applications. A system cal...

Does the social safety net improve welfare? Conventional wisdom says that means-tested social safety net programs improve welfare because they provide partial insurance against large negative shocks by guaranteeing a minimum consumption floor, but some economists have argued that they may also discourage labor supply and reduce capital accumulation. Furthermore, recent research suggests that th...

3. In practice, yearto-year changes i n the federal debt do not precisely equal the corresponding annual federal budget deficits. The inequality results because Congress borrows to finance net spending on certain off-budget programs, and because the Treasury finances a small portion of the deficit through changes i n various assets such as its cash balances. Here we use the term deficit to refe...

Overseas migration of the small brown planthopper, Laodelphax striatellus (Fallén), occurs during the winter wheat harvest season in East Asia. Knowing the take-off time of emigrating L. striatellus is crucial for predicting such migrations with a simulation technique because winds, carriers of migratory insects, change continuously. Several methods were used in China and Japan from late May to...
