Abstract The balance of pseudomomentum is discussed and applied to simple elasticity, ideal fluids, the mechanics inextensible rods sheets. A general framework presented in which simultaneous variation an action with respect position, time, material labels yields bulk laws jump conditions for momentum, energy, pseudomomentum. example elasticity space-filling solids treated at length. fluids sho...

Abstract. The surface mass balance scheme dEBM (diurnal Energy Balance Model) provides a novel interface between the atmosphere and land ice for Earth system modeling, which is based on energy of glaciated surfaces. In contrast to empirical schemes, accounts changes in Earth’s orbit atmospheric composition. only requires monthly forcing (precipitation, temperature, shortwave longwave radiation,...

Many morphogenetic processes are accomplished by coordinated cell rearrangements. These rearrangements are accompanied by substantial shifts in the neighbor relationships between cells. Here we propose a model for studying morphogenesis in epithelial sheets by directed cell neighbor change. Our model describes cell rearrangements by accounting for the balance of forces between neighboring cells...

Do securitized loans differ from loans held on lenders’ balance sheets? If so, why? We assemble a unique dataset of commercial mortgages with information on loan characteristics at origination and subsequent performance. The most significant difference between securitized (CMBS) and balance sheet loans is the loan size. The largest loans are 42 percentage points more likely to be securitized th...

Abstract. Ice losses from the Greenland and Antarctic ice sheets have accelerated since 1990s, accounting for a significant increase in global mean sea level. Here, we present new 29-year record of sheet mass balance 1992 to 2020 Sheet Mass Balance Inter-comparison Exercise (IMBIE). We compare combine 50 independent estimates derived satellite observations temporal changes flow, volume, Earth's...
