We consider a model of liquidity demand arising from a possible maturity mismatch between asset revenues and consumption. This liquidity demand can be met with either cash reserves (inside liquidity) or via asset sales for cash (outside liquidity). The question we address is, what determines the mix of inside and outside liquidity in equilibrium? An important source of inefficiency in our model...

Connexin protein can form single-membrane spanning channels (called hemichannels or connexons) that can dock with each other to span two closely apposed plasma membranes and thereby create gap junction channels. What keeps unapposed connexin hemichannels closed, and how do they open when part of junctional channels? The report from Tang et al. (2009) in this issue (see p. 555), along with a rec...

Health care education is developing at a high pace, all around the world. New ideas are needed, new ideas that work and help us meet the goals we set for improving health care education. PME wants to contribute to seeing with new eyes by offering its readers articles that are inspirational by nature. Articles with new ideas or with research based on new ideas that work. This inspiration combine...

The accurate estimation of flood risk depends on, among other factors, a correct delineation the floodable area and its associated hydrodynamic parameters. This characterization becomes fundamental in hazard analyses that are carried out urban areas. To achieve this objective, it is necessary to have topography, both inside riverbed (bathymetry) outside it. Outside riverbed, LiDAR data led an i...
