Using a normalized CES function with factor-augmenting technical progress, we estimate a supply-side system of the US economy from 1953 to 1998. Avoiding potential biases that have occurred in earlier estimations and putting a high emphasis on the consistency of the data set, required by the estimated system, we obtain robust results not only for the aggregate elasticity of substitution but als...

We determine the equilibrium morphology of a strained solid lm for the case where it wets the substrate (Stranski-Krastanow growth). Using a continuum elasticity model with isotropic surface energy and equal elastic constants in the lm and substrate, we calculate an asymptotic solution for the axisymmetric three-dimensional equilibrium shape of a small island, where the height is much less than...

In the bone marrow, hematopoietic stem cells (HSCs) reside in endosteal and vascular niches. The interactions with the niches are essential for the maintenance of HSC number and properties. Although the molecular nature of these interactions is well understood, little is known about the role of physical parameters such as matrix elasticity. Osteoblasts, the major cellular component of the endos...

Energy awareness of database systems has emerged as a critical research topic, because energy consumption is becoming a major factor. Recent energy-related hardware developments tend towards offering more and more configuration opportunities for the software to control its own energy-based behavior. Existing research within the DB community so far mainly focused on leveraging this configuration...

This paper studies the role of land as a factor of production in a simple monopolistic competition model of trade and geography. Overall we find that land for production is a powerful dispersion force. More specifically, we show that, in contrast to the new trade literature, a larger country will have lower wages, in general. Moreover, allowing for labor mobility, we show that agglomeration is ...

Human behavior has the positive and negative impact on ecosystem. To study the interaction between ecosystem and behavior system, per-capita energy ecological footprint (EEF) is selected as the ecosystem threshold. Elasticity coefficient of environmental investment (ECEI) and elasticity coefficient of energy consumption (ECEC) represent the positive and negative human impact on ecosystem, respe...

The components of the mechanical systems like machines and/or technological equipment have a certain elasticity or rigidity. Knowing the rigidity of each component is very important for the studies whose goal is to establish the dynamic efforts and the stresses in each shaft, gear wheel, steel structure, aso. The rigidity can be an important factor for the dynamic load estimation process. The c...

When making judgments, one may encounter not the appearance of a candidate into consideration, even only justifiable factors, i.e., attributes which the judge though she may want to hire the better-looking candithinks that he/she should take into consideration, but date. In this article, we distinguish between two types also unjustifiable factors, i.e., attributes which the of factors: (a) fact...

This study tests the importance of Ricardian technology di¤erences for international trade. Panel regressions …nd technology growth increases manufacturing exports. To establish a causal relationship between technology and trade, instrumental-variables speci…cations exploit uneven technology di¤usion from the US through ethnic scienti…c networks. The instrumented elasticity of export growth to ...

Elasticity is the ability of a software system to dynamically scale the amount of the resources it provides to clients as their workloads increase or decrease. Elasticity is praised as a key advantage of cloud computing, where computing resources are dynamically added and released. However, there exists no concise or formal definition of elasticity, and thus no approaches to quantify it have be...
