Because of its use in on-board hydrogen portable hydrogen-air fuel cell, hydrogen generation based on the reaction between aluminum and water was evaluated. In the present work, the effect of CoCl2 and NiCl2 on aluminum–water reaction was studied. The amount of hydrogen generated linearly...

A large, by a factor of ≈103−104, enhancement of Hall effect in cosputtered magnetic granular metals such as (NiFe)x-(SiO2)1−x near the metal-insulator transition has been termed giant Hall effect (GHE). It is associated with a high resistivity which increases slowly with decreasing...

Facebook’s Gross National Happiness (FGNH) indexes the positive and negative words used in the millions of status updates submitted daily by Facebook users. FGNH has face validity: it shows a weekly cycle and increases on national holidays. Also, happier individuals use more positive words and...

The YinNan Irrigation District in NingXia, China diverts each year about 1.6 - 109 m3 water from the Yellow River for irrigation use. More than half of that water is discharged back to the downstream channel or some low-lying depressions as a result of agricultural drainage. Several studies...

Corporations in many countries are run by controlling shareholders whose cash flow rights in the firm are substantially smaller than their control rights. This separation of ownership and control allows the controlling shareholders to pursue private benefits at the cost of minority investors by...

Many economic decisions can be described as an option exercise or optimal stopping problem under uncertainty. Motivated by experimental evidence such as the Ellsberg Paradox, we follow Knight (1921) and distinguish risk from uncertainty. To afford this distinction, we adopt the multiple-priors...
