＜正＞Nonclassical light beams generated by degenerate and non-degenerate optical parametric oscillators （ OPO） have played a significant role in studies of squeezing, entanglement and other nonclassical properties of light. Fluctuation properties of these nonclassical light beams have been studied by using various coherent state representations of the field density matrix. Here we discuss the use of positive-P representation of the density matrix

＜正＞Fluctuations of light provide a window on the underlying quantum dynamical evolution of the source emitting light. Emission of a photon by a source signals quantum fluctuations in progress. Hence a measurement that is conditioned upon a photodetection allows us to follow the time evolution of the fluctuations and the framework of conditioned measurements provides a powerful conceptual tool for understanding nonclassical features of quantum dynamics. We discuss the connection between quantum dynamics and photon fluctuations in terms of conditional

Characterization of soil hydraulic properties is important to environment management; however, it is well recognized that it is laborious, time-consuming and expensive to directly measure soil hydraulic properties. This paper reviews the development of pedotransfer functions （PTFs） used as an alternative tool to estimate soil hydraulic properties during the last two decades. Modern soil survey techniques like satellite imagery/remote sensing has been used in developing PTFs. Compared to mechanistic approaches, empirical relationships between physical properties and hydraulic properties have received wide preference for predicting soil hydraulic properties. Many PTFs based on different parametric functions can be found in the literature. A number of researchers have pursued a universal function that can describe water retention characteristics of all types of soils, but no single function can be termed generic though van Cenuchten （VG） function has been the most widely adopted. Most of the reported parametric PTFs focus on estimation of VG parameters to obtain water retention curve （WRC）. A number of physical, morphological and chemical properties have been used as predictor variables in PTFs. Conventionally, regression algorithms/techniques （statistical/neurM regression） have been used for calibrating PTFs. However, there are reports of utilizing data mining techniques, e.g., pattern recognition and genetic algorithm. It is inferred that it is critical to refine the data used for calibration to improve the accuracy and reliability of the PTFs. Many statistical indices, including root mean square error （RMSE）, index of agreement （d）, maximum absolute error （ME）, mean absolute error （MAE）, coefficient of determination （r2） and correlation coefficient （r）, have been used by different researchers to evaluate and validate PTFs. It is argued that being location specific, research interest in PTFs will continue till generic PTFs are developed and validated. In future studi

A number of herbs belonging to the genus Jatropha of Euphorbiaceae family are noted for their medicinal benefits. The genus Jatropha is one of the prospective biodiesel yielding crops. The plants which have been so far explored include J. curcas, J. gossypifolia, J. glandu/ifera, J. multifida and J. podagrica. Although, the plants of this genus are widely distributed, there is an exiguity of scientific literature proclaiming the medicinal benefits of the plants belonging to genus Jatropha. The present paper is a pragmatic approach to accrue the findings on this very significant genus.

The expected rise in temperature and decreased precipitation owing to climate change and unabated anthropogenic activities add complexity and uncertainty to agro-industry. The impact of soil nutrient imbalance, mismanaged use of chemicals, high temperature, flood or drought, soil salinity, and heavy metal pollutions, with regard to food security, is increasingly being explored worldwide. This review describes the role of soil-plant-microbe interactions along with organic manure in solving stressed agriculture problems. Beneficial microbes associated with plants are known to stimulate plant growth and enhance plant resistance to biotic （diseases） and abiotic （salinity, drought, pollutions, etc.） stresses. The plant growth-promoting rhizobemteria （PGPR） and mycorrhizae, a key component of soil microbiota, could play vital roles in the maintenance of plant fitness and soil health under stressed environments. The application of organic manure as a soil conditioner to stressed soils along with suitable microbial strains could further enhance the plant-microbe associations and increase the crop yield. A combination of plant, stress-tolerant microbe, and organic amendment represents the tripartite association to offer a favourable environment to the proliferation of beneficial rhizosphere microbes that in turn enhance the plant growth performance in disturbed agro-ecosystem. Agriculture land use patterns with the proper exploitation of plant-microbe associations, with compatible beneficial microbial agents, could be one of the most effective strategies in the management of the concerned agriculture lands owing to climate change resilience. However, the association of such microbes with plants for stressed agriculture management still needs to be explored in greater depth.
