Predictive simulations of the shock-to-detonation transition (SDT) in heterogeneous energetic materials (EM) are vital to design and control their energy release sensitivity. Due complexity thermo-mechanics EM during SDT, both macro-scale response sub-grid mesoscale localization must be captured accurately. This work proposes an efficient accurate multiscale framework for SDT EM. We introduce a...

The propagation of macroeconomic shocks through input-output and geographic networks can be a powerful driver of macroeconomic fluctuations. We first exposit that in the presence of Cobb-Douglas production functions and consumer preferences, there is a specific pattern of economic transmission whereby demand-side shocks propagate upstream (to input-supplying industries) and supply-side shocks p...

The average unemployment rate for 1997 was 4.9 percent, well below most estimates of the nonaccelerating inflation rate of unemployment (NAIRU).1 One would therefore have expected to see an increase in inflation in 1997; yet, as measured by the CPI, inflation fell from 3.3 percent to 1.7 percent (December to December). This phenomenon of low unemployment accompanied by falling inflation has pro...

Input-output tables describe the flows of goods and services between the sectors of an economy. These tables can be interpreted as weighted directed networks. At the usual level of aggregation, they contain nodes with strong self-loops and are almost completely connected. We derive two measures of node centrality that are well suited for such networks. Both are based on random walks and have in...

We analyze price adjustments in the housing market after an exogenous shock. Exploring continuous-time records of prices around a major European airport (ZRH, Switzerland), and an unexpected change in flight regulations induced by the neighboring country Germany, we find that apartment rents take about two years to stabilize to a new equilibrium value. After this period we find a constant marku...

Ischemia-reperfusion (IR) liver injury is associated with temporary clamping of hepatoduodenal ligament during liver surgery, hypoperfusion shock and graft failure after liver transplantation. Mechanisms of IR liver injury include: i) loss of calcium homeostasis, ii) reactive oxygen and nitrogen species generation, iii) changes in microcirculation, iv) Kupffer cell activation, and (v) complemen...

The porcelain crab Petrolisthes cinctipes lives under rocks and in mussel beds in the mid-intertidal zone where it experiences immersion during high tide and saturating humid conditions in air during low tide, which can increase habitat temperature by up to 20°C. To identify the biochemical changes affected by increasing temperature fluctuations and subsequent heat shock, we acclimated P. cinct...

In the standard New Keynesian model, monetary policy is often described by an interest rate rule (e.g. a Taylor rule) that moves the interest rate in response to deviations of inflation and some measure of economic activity from target. Nominal interest rates are bound from below by 0 – since money is storable, one would never accept a negative nominal return. How does the behavior of the NK mo...
