Soil evaporation can signifi cantly infl uence energy fl ux partitioning of partially vegetated surfaces, ultimately affecting plant transpiration. While important, quantifi cation of soil evaporation, separately from canopy transpiration, is challenging. Techniques for measuring soil evaporation exist and continually improve. The large variability in soil water content requires that there be c...

This paper investigates forecasts of US in#ation at the 12-month horizon. The starting point is the conventional unemployment rate Phillips curve, which is examined in a simulated out-of-sample forecasting framework. In#ation forecasts produced by the Phillips curve generally have been more accurate than forecasts based on other macroeconomic variables, including interest rates, money and commo...

In supersymmetric theories a eld can develop a vacuum expectation value M 10GeV, even though its mass m is of order 10 to 10GeV. The nite temperature in the early Universe can hold such a eld at zero, corresponding to a false vacuum with energy density V0 m 2 M . When the temperature falls below V 1=4 0 , the thermal energy density becomes negligible and an era of thermal in ation begins. It en...

The so-called Fed model postulates that the dividend or earnings yield on stocks should equal the yield on nominal Treasury bonds, or at least that the two should be highly correlated. In US data there is indeed a strikingly high time series correlation between the yield on nominal bonds and the dividend yield on equities. This positive correlation is often attributed to the fact that both bond...

The union of high-energy particle theories and gravitation often gives rise to an evolving strength of gravity. The standard picture of the earliest universe would certainly deserve revision if the Planck mass, which de nes the strength of gravity, varied. A notable consequence is a gravity-driven, kinetic in ation. Unlike standard in ation, there is no potential nor cosmological constant. The ...

In the Local Computation Algorithms (LCA) model, the algorithm is asked to compute a part of the output by reading as little as possible from the input. For example, an LCA for coloring a graph is given a vertex name (as a “query”), and it should output the color assigned to that vertex after inquiring about some part of the graph topology using “probes”; all outputs must be consistent with the...

It’s easy to check that any specific string of length n has probability at most (1 − δ), hence SV-sources are n log 1 1−δ -sources. Also recall that SV-sources are (k, l) block sources where k = l log 1 1−δ . Suppose δ = log 1 1−δ , then k = δl. Take a hash-based extractor E : {0, 1} × {0, 1} → {0, 1}. Here, our weak-source is a SVsource over the strings of length n and suppose k = n log 1 1−δ ...

a study published in the previous issue of Critical Care, Gonçalves and colleagues [1] observed a 33% reduction in re-intubation rate in the study group, due to eff ective management of bronchial secretions. Current evidence favors early implementation of noninvasive mechanical ventilation (NIV) in the post-extubation period to reduce re-intubation, especially in patients with hypercapnic respi...
