Significant decline in the slope of short-term oil supply and demand curves, along with the meaningful change in the degree of risk aversion in arbitrageurs encouraged us to test the time-varying effects of speculative demand on crude oil price dynamics over the period 1985-2016. Using a time-varying parameter vector autoregressive (TVP-VAR) model – with structural shocks identified by Killian ...

China is considered to be the main carbon producer in the world. The per-capita carbon emissions indicator is an important measure of the regional carbon emissions situation. This study used the LMDI factor decomposition model-panel co-integration test two-step method to analyze the factors that affect per-capita carbon emissions. The main results are as follows. (1) During 1997, Eastern China,...

The theory of factor demand has important implications for the study of the impact of immigration on wages in both sending and receiving countries. This paper examines the implications of the theory in the context of a general equilibrium model where the wage impact of immigration is influenced by such factors as the elasticity of product demand, the rate at which the consumer base expands as i...

The proliferation of R&D tax incentives among U.S. states in recent decades raises two important questions: (1) Are these tax incentives e¤ective in achieving their stated objective, to increase R&D spending within the state? (2) To the extent the incentives do increase R&D within the state, how much of this increase is due to drawing R&D away from other states? In short, this paper answers (1)...

Transplantation of microencapsulated cells has been proposed as a cure for many types of endocrine disorders. Alginate-based microcapsules have been used in many of the feasibility studied addressing cure of the endocrine disorders, and different cancer types. Despite years of intensive research it is still not completely understood which factors have to be controlled and documented for achievi...

Radiation force-based elasticity imaging is currently being investigated as a possible diagnostic modality for a number of clinical tasks, including liver fibrosis staging and the characterization of cardiovascular tissue. In this study, we evaluate the relationship between peak displacement magnitude and image quality and propose using a Bayesian estimator to overcome the challenge of obtainin...

The I-band region of the giant muscle protein titin contains a large domain enriched for the amino acids proline, glutamate, valine, and lysine and is denoted the PEVK domain. The PEVK domain of titin encodes a random coil shown to be an important factor in the passive elasticity of titin. Muscle-specific splicing of 116 PEVK exons encodes this domain. It has been proposed that proline contents...

The phenomenon of fiscal illusion has always been an intriguing topic in the public finance literature. Fiscal illusion is a concept in which misinterpretation of fiscal parameters and tax expenses and liabilities lead to bias in budgetary decision making at all levels of the government. The current research presents an empirical analysis of the fiscal illusion in the Iranian economy, using fiv...

Material property has great importance in deformable body simulation and medical robotics. The elasticity parameters, such as Young's modulus of the deformable bodies, are important to make realistic animations. Further in medical applications the (recovered) elasticity parameters can assist surgeons to perform better pre-op surgical planning and enable medical robots to carry out personalized ...

Magnetic resonance elastography (MRE) is a promising method for health evaluation and disease diagnosis. It makes use of elastic waves as a virtual probe to quantify soft tissue elasticity. The wave actuator, imaging modality and elasticity interpreter are all essential components for an MRE system. Efforts have been made to develop more effective actuating mechanisms, imaging protocols and rec...
