1. The transmural electrical potential difference (PD) of the intact human small intestine was recorded with close attention to electrical symmetry, shielding from electro-magnetic waves and correction for junction potentials. 2. The PD is -12 mV (mucosa-negative) in the fasting jejunum and ileum and does not change during perfusion with isotonic NaCl. 3.(More)
We will discuss several recent advances in agent-based modeling, with applications to mass egress and wide-area evacuations following disasters. These advances include: efficiency improvements in specifying people's identification and selection of exit routes, making it possible to handle up to 70,000 people-agents; incorporation of new crowd movement(More)
