Accurate forecasting of zero coupon bond yields for a continuum of maturities is paramount to bond portfolio management and derivative security pricing. Yet a universal model for yield curve forecasting has been elusive, and prior attempts often resulted in a trade-off between goodness of fit and consistency with economic theory. To address this, herein we propose a novel formulation which conn...

technique of remote sensing and its satellite products has many implementations in agricultural science and national resources. in this study, wheat yield in esfahan province, iran, were derived from modis satellite data over periods of 2000-2001(dry year) and 2004-2005 (wet year). for this purposes, 68 modis products of surface reflectance (mod09ga) and land surface temperature lst (mod11a2) o...

Phase sensitive Surface Plasmon Resonance (SPR) techniques are a popular means of characterizing biomolecular interactions. However, limitations due to the narrow dynamic range and difficulty in adapting the method for multi-point sensing have restricted its range of applications. This paper presents a compact phase sensitive SPR technology using a custom CMOS camera. The system is exceptionall...

Vertisols occur extensively in centralIndiaand have high production potentials. Because of the high clay content (40-60% or more), high bulk density (1.5-1.8 Mg m-3) and related properties, these soils have high moisture storage capacity. Conversely, these soils become very hard when dry and very sticky when wet. Since last two decades, scientists, farmers and also the policy makers have be...

The paper studies the quasistatic evolution for elastoplastic materials when the yield surface depends on the position in the reference configuration. The main results are obtained when the yield surface is continuous with respect to the space variable. The case of piecewise constant dependence is also considered. The evolution is studied in the framework of the variational formulation for rate...

The spatial variation of crop yield was mainly caused by the complicated factors, such as soil and land factors. Based on sound theoretical reasoning, the paper performed an exploratory investigation of the relationship between the spatial distribution of yield measurement about 849 samplings on Thiessen polygon. Reasonable sample size or sampling density is an assurance of yield estimation sur...

Nuclear magnetic resonance, surface plasmon resonance and fluorescence spectroscopy (particularly fluorescence anisotropy and fluorescence lifetime) are techniques often applied to fragment screening. These methodologies are analyzed on the basis of their performance, strengths, limitations and pitfalls. NMR-based screening, despite its low intrinsic sensitivity, offers the largest dynamic rang...

This paper proposes a model to better capture persistent regime changes in the interest rates of the US term structure. While the previous literature on this matter proposes that regime changes in the term structure are due to persistent changes in the conditional mean and volatility of interest rates we find that changes in a single parameter of the model we use better models regime changes. F...
