diffusion weighted imaging uses the signal loss associated with the random thermal motion of water molecules in the presence of magnetic field gradients to derive a number of parameters that reflect the translational mobility of the water molecules in tissues. with a suitable experimental set-up, it is possible to calculate all the elements of the local diffusion tensor (dt) and derived paramet...

agricultural activities are risky activities. in these activities, various natural, social and economic risks have created fragile and vulnerable situation for producers. price risk in agricultural products has caused financial problems for many producers and farmers. to deal with these price risks and price fluctuations, there are varieties of tools. this paper focused on futures markets instr...

We consider the problem of decomposing an observed input matrix (or vector sequence) into the product of a mixing matrix with a component matrix , i.e. , where (a) the elements of the mixing matrix and the component matrix are non-negative, and (b) the underlying components are considered to be observations from an independent source. This is therefore a problem of non-negative independent comp...

Microbial electrosynthesis (MES) has been highlighted as a means to valorize inorganic gaseous carbon, such CO2, into value-added chemicals using electricity the reducing power. Electrode-based electron transfer delivers respiratory electrons live-cell biocatalyst through biofilm matrix or via shuttle molecules. The addition of artificial mediators, neutral red (NR) and 2-hydroxy-1,4-naphthoqui...
